    The drilling beam boom (500) of the drilling rig of the invention has a first end (512) and a second end (509), and the second end is, when using the drilling rig against the drilling direction, a guide (514) movable along the drilling beam boom, which guide has a rotary unit (508) and catch jaws and at least two drive means (502, 511) for moving the guide. The drive means are attached to the guide, either directly or by means of a transmission mechanism. A pipeline is determined by the drill pipe and straight lines determined by the drive means are substantially in the same plane. The pipeline is between the straight lines determined by the drive means and divides the level into a first part and a second part, and the actual values of the moment M1 caused by the drive means in the first part and the moment M2 caused by the drive means in the second part are essentially of the same order of magnitude. The plane is inclined in the direction of the drilling rig, where the drill pipe is handled. The straight lines defined by the drive means define a plane, and the pipeline is in this plane or is positioned relative to this plane so that the moments caused by the drive means behave in the manner described above. The drive means may be hydraulic cylinders, the parts being arranged to move so that the total length of the drive means changes.

    1015202530drill pipe segments. A drill pipe segment is provided at both ends with threads,by means of which several segments can be joined. The length of a segmentis usually 3 meters, but there are also, for example, drill pipe segments with onelength of 1.5 meters on the market. When drill pipe segments are joined underdrilling, long uniform drill pipes are provided during drilling, with whichthe rock can be drilled very deep in, even several kilometers.
    The lower end of the drill beam boom is the end ofthe drilling beam boom, which is in the direction of the drilling direction, and thethe upper end is the other end of the drill beam boom. It should be pointed outthat the lower end of the drilling beam boom may in some cases be higher thanthe upper end. This may be the case, for example, in mines, where drilling is possibleperformed upwards. At the upper end of the bore beam boom is ingenerally a separate extension beam beam, which is a few meters long, towhich e.g. a gutter or similar structure is attached which makes handlingof the drill pipe simpler, which structure supports the upper end ofthe drill pipe segment when threaded connections between the segments have not been screwed togethercompletely closed. In addition, for example, an unpowered wheel of a winch whichneeded to lift samples in test well be attachedextension beam bar.
    During drilling, the drilling rig is taken or traveled by own machinethe drilling site. There, the drilling beam boom is located exactly at the drilling point,directed in the right direction and set at the right angle of inclination. The drilling beam boom isthus positioned for drilling. In boreholes that occur at the ground surface canthe angle of inclination usually varies in the range of 10 ° - 90 °, i.e. from an almosthorizontal drilling to a vertical. In mines or the like, drilling canperformed in virtually all directions. When the drilling rig and drill pipe are aligneda first drill pipe segment is installed in the rotation unit in the beam boom, in itlower end of said segment is a blade and other components whichrequired when drilling, such as broachers, placed. Other devices such asneeded in the drilling, such as a core pipe, and a water tether pipe, are alsoinstalled in the drill pipe. In the drilling process, drilling water or other is used1015202530drilling aids that are led into the drill pipe through the water tether pipe as oneaids, such as drilling aids lubricate the drilling process as it passesthe blade and removes rock clay generated when drilling from the borehole whenit rises out of the tube.
    The drill pipe with its blades and other devices is inserted through a hole inthe center of the rotation unit. The rotation unit has catch jaws, which take onefirmly hold the drill pipe. When the drill pipe is pressed between the catch jaws andthe rotation unit rotates the catch jaws and the drill pipe is attached to them, and onat the same time the drive means, such as the hydraulic cylinders belonging to itstructure of the drilling beam boom, the drill pipe is pressed in the drilling direction andthe blade at its lower end against the rock with a suitable force, drill the drill pipe intothe mountain. Rotational force of the blade comes from a rotary motor inthe rotation unit, which motor is connected to the rotation jaws via aGear system. These all belong as bearing parts to the rotating unit, whichinstalled in the guide that slides in the drilling beam boom. Drilling beam boomalso has at least one lower jaw set, which jaws are always pressed againstthe tube before the catch jaws of the rotary unit are opened. This must be donewhen moving the rotation unit to the other end of the guideway. Toexample when drilling, the guide is moved to the upper end ofthe drilling beam boom when the stroke is completed, from where it is pressed againdownwards with drive means, when the catch jaws have gripped the pipe, and incorrespondingly, when lifting the drill pipe, the guide is moved to the lower end ofthe drilling beam boom when the stroke is complete before a new lifting movement. Ifthe line is already partially lifted and the lower catch is not used, canthe drill pipe fall back to the bottom of the hole, which in some cases can result in aloss of the drill pipe and even prevent continued drilling.
    Mains voltage during drilling, ie the effect with whichthe drill pipe is pushed into the hole, is generally not very large, but for example whenthe blade has worn out, all drill pipe segments in the borehole must be lifted out of the hole, tooto be able to replace the blade. When drilling is performed deep and it can evenbe thousands of meters of pipe in the borehole, the weight of the drill pipe and the water is it1015202530contains very large. The weight is also enhanced by a frictional effect betweenthe pipe and the borehole. Thus, an ability to provide a very large lift is requiredfrom the drilling beam boom at the beginning of the suspension of the pipes.
    For example, in a borehole approximately two kilometers deep, one is neededLifting force of approximately 150 kN at the beginning of the lifting of the drill pipe, which corresponds to oneweight of about 15,000 kg. This force is transmitted via the catch jaws rotation unitand the frame of the rotating unit to the structures of the guide and further viaa power transmission to the drive means of the guide. The effect needed tolifting the pipes is also a heavy load on the drill beam boom, so thatthe structure of the beam boom must be very strong.
    Figure 1 shows an example of a drilling machine 100 and its use.
    For the sake of clarity, certain parts have been omitted in the figure. The drilling rig andits apparatus is protected by a frame 101. The drilling rig has a drilling beam boom103, which has a guide having a rotating unit 104 for rotating the drill pipe105. During ground drilling, the pipe is protected by a ground wire 108, which preventsloose soil from falling into the borehole. To understand the operation ofthe drilling beam boom, it can be considered that the drilling beam boom has oneopposite upper surface and lower surface and side surfaces between them. The upper surface ofthe drill beam boom is the part of the drill beam boom whenthe drilling beam boom is in drilling readiness, which is upwards when you turndrilling beam boom in horizontal position. The lower surface ofthe bore beam boom, on the other hand, is the part of the bore beam boom,which is against the floor of the drilling rig, when the drilling beam boom is tilted as when itis in drilling readiness. It should be noted that the drilling beam boom, which hasthe upper surface defined above and the lower surface, can be rotated to bevertical, but the definition of the surfaces is valid even in this case.
    The drilling beam boom has an open surface 107 arranged for handlingthe drill pipe and for the distance of the drill pipe segments, which open surface in thisthe application for the sake of clarity is called a handling area. The handling surface forthe drill pipe enables manual handling of the drill pipe and drill pipe segments,since the frame or other parts of the drill beam boom do not prevent this.1015202530The handling surface for the drill pipe is on the upper surface of the drilling beam boom.
    The handling surface for the drill pipe is of such a size that the drill pipe andthe drill pipe segment can be handled, for example the drill pipe segment can be liftedthe drill beam boom and attached to the end of the drill pipe as a continuationon the drill pipe. To make the handling of the drill pipe easier, an extension canof the beam boom be connected to the drilling beam boom, for example tosupport the drill pipe as it lifts from the borehole.
    Usually a drilling rig has at least two workers. One of them is the driller102, which uses actuators on the rig. Among other things, he makes sure that rightratio is used between speed and feed rate of drilling and tothe lifting of the drill pipe from the borehole, which is done with machine power. Oneassistant drill 106 acts as a support for the drill, whichthe assistant driller usually works standing on the opposite side ofthe drilling beam boom opposite the drill. The tasks for itthe assistant drill consists of lifting drill pipe segments loaded intothe drill beam boom to the drill pipe handling surface 107 and assemblyof the threaded joints in drill pipe segments. When the assistant drill has screwedthe beginning of the threaded connection between the drill pipe segments by hand andensuring that the threads are in place, the drill in the threaded joints rotates to the endmechanically, whereby also the final tightening of the wires is performed. Duringlifting of the pipes, the opening of the threads takes place completely mechanically.
    Figure 2 shows a drilling rig 100 from the side. The drilling rig is on the bottom surface206 on the support legs. The length of the support legs can be adjusted to get the positionfor the drilling rig to be ideal. The drilling rig has a roof structure 201, which protectscrew and rig from weather and which also includes a pipe stand, onwhich drill pipe segment lifted from the hole may be stacked. Roof constructionthe tion is attached to the frame 101 of the drilling rig. Under the drilling beam boomthere is usually an arrangement that is based on screw motor technology and encounteredthe floor frame of the drilling rig, by means of which arrangementthe drilling beam boom is, in addition to being adjusted at the correct drilling angle, also lockedand supported in a desired tilt position, until the hole is drilled all the way. This1015202530arrangements are for the sake of clarity not shown in the figure. At the upper end ofthe bore beam boom is an extension beam boom 204. At the upper endof the extension beam bar is the intermediate wheel 205 of a winch, throughwhich wheel a winch wire runs, for example, for the purpose of lifting drill cores frominside of the drill pipe. At the lower end of the rotating unit 104, i.e. indirection towards the lower end of the drilling beam boom there are catch jaws202 to grip the drill pipe. Catch jaws transmit both the rotational movement andpulling and pushing movements to the drill pipe. The rotational movement is provided by arotary unit and the pulling and pushing movements of drive means. Line 203 ofthe drill pipe is marked with a dashed line in the figure. The drill pipe is onthe drill pipe.
    In Figure 1, the drill pipe is lifted. Here, the drilling rig has lifted the drill pipe over a length ofabout 6 meters. The guide and catch jaw that holds the pipe in place are in the upper onethe part of the drilling beam boom. The drilling rig has an open threaded connection betweenthe pipe segments. This part independent of the drill pipe is supported onextension beam bar, which extension beam bar is not shown in the figure.
    The assistant drill manually lifts the 6 meter long part of the drill pipe asconsists of two pipe segments from the drilling beam boom and sets it aside,so that the drilling rig can lift up new drill pipe segments. By doing soway, the drill pipe can be lifted from the entire depth of the borehole.
    Many assistance devices have been developed for pipe handling such asmanually performed by the assistant driller, but so far has the fastest, mostreliable and most efficient working method nevertheless proved to be that pipe handlingperformed with muscle strength of the assistant drill. Therefore, it is important thatthe construction of the drilling beam boom is open in such a way that itthe assistant driller has an unobstructed view of the drilling pipe that passesby rotary unit and that the positioning of drill pipe segments inthe rotating unit and lifting them from the rotating unit during liftingof the drill pipe is possible and easy. This has generally been solved by arranginga handling surface for the drill pipe on the upper surface of the drilling beam boom ofdrilling rigs intended for manual use.1015202530In some drilling beam barriers, the placement of drive means has been made so thatin the inner part of the baik boom structure below the rotation unit there isa rather large hydraulic cylinder that touches the guide. The power of the hydraulicthe cylinder is transferred in these models to the guide either with achain transmission and drive wheels or with a power arm mounted betweenthe cylinder and the guide. In this construction, a moment arm is quartz betweenthe center line of the hydraulic cylinder (cylinder power line) and the pipeline(lifting force caused by the weight of the pipes). This torque arm is approximately 200-400 mm, depending on the type of device. Although the distance between the cylinderthe center line and the pipeline are not very far, it causes, however, ondue to large lifting forces, a torque effect that greatly bends the structure ofthe beam boom. The problem is also somewhat repetitive, becausethe torque effect also causes increased frictional forces in the sliding guide groove betweenthe guide for the rotation unit and the frame of the beam bar. In small andmedium-sized chain transmission models, where the drilling depth is from a few hundredmeters to about one kilometer, this bending problem has been solved bydimension the construction of the beam boom to be strong enough. Thishowever, increases manufacturing costs and increases the weight of the structureswhich may cause use restrictions for the drilling rig. The structuresalso need parts belonging to the transmission mechanism, such as chains,intermediate wheels, axles and bearings. In the event of wear, these cause a need for service andfurther increases manufacturing costs. Especially in larger models, therethe drilling depth is about 1500-2000 meters, the power transmission between is realizedthe cylinder and the guide with a power arm instead of a chain transmission. Whendrilling depth increases, serious bending moment problems occur in these larger onesdrilling beam boom models, which problems are caused by, in addition to majorlifting forces, even the larger torque arm. The torque effect causes problemswith respect to rigidity in the bore beam boom. Bending is directed, in additionof the drilling beam boom, also of the hydraulic cylinder, which isvery harmful to the cylinders. When the cylinder bends, very small ones come loosemetal particles inside it, which can also destroy othershydraulic components. Replacing the cylinder itself also incurs a lotcosts, as it is always an expensive special cylinder. Since1015202530the expected life of the cylinder is shortened due to bending and ondue to a changed need for other hydraulic components and increasedservice due to bending, the costs of using the rig are high inrelation to drilling meters. In such drilling beam boom models is the pipelineopen upwards, i.e. when the drill beam boom tilts the hydraulic cylinder and theyparts needed for power transmission are in the part of the drilling beam boomwhich is closer to the ground. The assistant driller can thus be easily obtainedthe tubes in the rotary unit, but the assistant drill must bendthe drilling beam boom. Such a drilling rig is shown in Figures 1 and 2.
    Drilling beam barriers are also known, which otherwise correspond to itthe above-described drilling beam boom, but which instead of onehydraulic cylinder has two smaller cylinders and both cylinders have their ownarrangements for transmitting power to the guide. These cylinders andpower transmission arrangements are located on both sides of the pipelineand not on the underside of the pipeline. In the same way, the slides are forthe guide and the support beam structure of the drilling beam boom placed on bothsides of the pipeline. Thus, a torque effect caused bythe lifting force and load on the drilling beam boom is reduced. One problem remains inthat the pipeline remains hidden between the frame structure on its sides, andthe structure of the drilling beam boom becomes wide. Because of the largethe structure and that the pipeline is deep inside the beam boom can notthe assistant drill get a firm grip on the pipe segment or simply put them onright place. When it takes a lot of muscle strength to move manuallypipe segments due to their weight, need ergonomic lifting positionsbe used, in addition to getting fluency at work, also due to occupational safety.
    Since this is not possible with the described bore beam barriers,handling that arises from muscle strength is in practice completely prevented inthis model. Thus, the only option left in this type ofdrilling beam boom to handle and place pipe segments to use onepipe handlers working with machine power. In practice, the pipe handling righowever, a slow and cumbersome way of doing this work. An experiencedassistant drillers perform the handling of drill pipe segments with a multiple1015202530speed compared to commonly used pipe handling rigs suitable forterrain. In addition, when the assistant drill due to the widebeam beam structure and the location of the drill pipe deep inside the beam beam does notcan start the joint threading by hand when the drill pipe segments are joined,the threaded connection must be made entirely with machine power. Under field conditions ishowever, the success is uncertain for an automatic threaded joint made ofmachine power from the beginning, which the driller can in no way affect.
    Because it is in threaded joints made by the machine is very difficult toprovide monitoring of the correct point to start screwingand make sure the threads really start to run properly, there will be breakageon the threads often when making automatic threaded joints. This, in addition tofurther slow down for drilling work, the drill pipe segments also break,which increases the cost of drilling.

    In the following, the invention will be described in detail. INthe description is referred to the accompanying drawings, in whichFigure 1 shows a known drilling rig,Figure 2 shows a cross section of a second known drilling rig viewed from the side,Figure 3 shows an example of a drilling rig having a drilling beam boomaccording to the invention,Figure 4 shows an example of a drilling beam boom according to the invention indifferent positions of the drive member and slide,Figure 5 shows an example of a drilling beam boom according to the inventionfrom above,Fig. 6 shows the drilling beam boom according to Fig. 5 from the side,1015202514Figure 7 shows the drilling beam boom according to Fig. 5 was examined from boththe ends and as a cross section in two points,Figure 8 shows an example of a drilling beam boom according to the inventionexamined in the direction from its first end andFigure 9 shows an example of a drilling beam boom according to Figure 8 examinedfrom the direction in which the handling of the drill pipes takes place.
    Figures 1 and 2 have been described in connection with the description of knowntechnique.
    The embodiments in the following description are given only asexample and a professional in the field can carry out the basic ideaaccording to the invention also in a manner other than that described in the description.Although the description may refer to a particular embodiment or embodiments ofseveral places, does not mean that the reference would be directed to only onedescribed embodiment or that the described characteristics couldbe used only in a described embodiment. The individual characteristics of twoor several embodiments can be combined and new embodiments ofthe invention can thus be provided.
    Figure 3 shows an example of a drilling rig 300 in a lateral cross-section, whichhas a bore beam boom 303 in accordance with the invention. The drilling rig has oneframe 309, which protects parts and users of the drilling rig, and a roof 301 whichcan be opened and moved, which for example also comprises a pipe rack, theredrill pipe segments that are lifted from the borehole can be stacked. The drilling rig also has onepower source. This can be, for example, an engine or a battery or acombination of these. The position of the frame in relation to the ground surface 312can be adjusted, for example, with adjustable support members. In addition, the drilling rig hasmeans for moving the drilling beam boom. Generally movedthe drilling beam boom in a plane defining the tilting angle, whichat the same time the slope of the drill pipe is 306. The direction of101520253015the drilling beam boom and the direction of the drill pipe line are selected with the positionat the frame of the drilling rig. There are also drilling rigs, where the direction ofthe drilling beam boom can be selected with the position of the drilling beam boom, but inthe rigs according to the figures, the lateral rotation takes place by turning the frame.
    The drill beam boom has a first end 302 and a second end 310. Itthe other end is facing the drilling direction, i.e. lower than the firstthe end when drilling in terrain. The drill beam boom has a rotation unit304, which has catch jaws 305 to hold the drill pipe in place and forpower transmission to the drill pipe. The rotation unit is moved alongthe drilling beam boom with a guide. The drilling beam boom has onedrilling pipe handling area 311, which is open for the drill pipe route anddrill pipe segments in the drilling beam boom.
    Current is led to the guide with the drive means 308. In the example there are twodrive means, but in the figure one of them is in the other part of the cross section andthus remains invisible. In the case according to the example, the drive means are hydraulic cylinders.
    Such a cylinder has two or more parts. One part goes inside the otherpart or coming out from inside the other part. So changesthe total length of cylinder. These movements are implemented with hydraulics,which derives its driving force from the power source of the drilling rig 300. About the different partsof the cylinder are attached to different targets, the forces can be directed between these targets. ToFor example, one part of the hydraulic cylinder is attached to the guide and the otherthe part is attached to the drilling beam boom and more precisely to itframe structure. Thus, the guide can be moved by changing the length of the cylinder. INthe figure is the second part of the hydraulic cylinder attached in the direction ofthe drilling beam boom to the first end 302 of the drilling beam boom,so that the other parts are partly outside the drilling beam boom and the firstthe part of the cylinder is arranged to go inside the other part. The first partof the cylinder is attached to the guide. Because the other part of the cylinder remainsin its place, the first part touches the guide when moving relative to itthe second part. About the catch jaws 305 attached to the rotation unit 304holding the drill pipe, forces in the direction of the drilling beam boom can thusdirected at the drill pipe. Because the other parts of the hydraulic cylinders are101520253016outside the drilling beam boom and in the direction of the drilling beam boom anddo not move during the drilling process, they can be used to replacethe extension beam boom either completely or partially.
    The bore beam boom 303 is in such a position that the handling surface 311for the drill pipe is inclined in the direction where the drill pipe and drill pipe segments are handled indrilling rig 300. This slope can be considered realized by turningthe drilling beam boom from a position where the handling surface of the drill pipe is on itupper surface of the drilling beam boom, by holding drill pipe 306 asaxis of rotation. Thus, the frame of the drilling beam boom can lie in those partsof the drilling beam boom, where it does not cover the handling surface of the drill pipeor otherwise prevents handling of the drill pipe. This slope allowseasier access to the handling surface of the drill pipe and the pipe handler, such as thatassistant drill, does not need to extend onto the drill beam boom.
    It should be noted that the slope is fixed and it has been made during the manufacture ofthe drilling beam boom.
    Figure 4 shows in detail an example of a drilling beam boom 400 accordinglywith the invention. The figure has three points, where the hydraulic cylinderswhich act as drive means from the drilling beam boom and the guide are in differentpositions.
    Figure 4 shows a bore beam boom 400 having a first end 402and a second end 412. When drilling, the other end is againstdrilling direction. The drill beam boom has a frame 408 to supportthe drilling beam boom and to protect its structures. The frame according tothe example has two parallelogram-shaped plates, which are in the direction ofthe structures of the drilling beam boom. The plates are assembled at theirlong sides. The frame can also have a part, whereby it is bent, or it canbuilt, for example, from separate beams and slabs, which are welded to oneuniform structure. The important thing is that the frame leaves a part ofdrilling beam boom open, so that the stretching of the drill pipe anddrill pipe segments in the drilling beam boom are available. This open part is called101520253017handling surface. In the example, the frame covers the lower surfacethe bore beam boom, i.e. the surface, which when twisted as it is setthe drilling direction may end up against the floor of the drilling rig. Also stretchesthe frame to the side of the bore beam boom, which is opposite that side ofthe drilling beam boom, from the direction in which the drill pipe is intended to be handled.
    The frame may also have support components and support members, but they areplaced so that they do not obstruct the handling of the drill pipe inthe drilling beam boom.
    The frame 408 also has end structures located at the ends ofdrilling beam boom 400. End structures have shapes for the drill pipe.The end structure at the first end 402 of the bore beam boom has a firstend mold 401 and the end structure at the second end 412 has a second end mold413. The shapes are advantageously such that the drill pipe is not belowthe drilling process hits the frame and that service can be easily performed.
    Inside the frame 408 there is a rotating unit 410, catch jaws, as inthis example is inside the rotation unit and is not visible in the figure, a guide414 for moving the rotary unit, a lower reverse set (not shown in the figure),guide groove 406 for controlling movements in the guide and for holding the guide in placeposition, and drive means: a first drive means 404 and a second drive means 407.
    The rotation unit 401 uses the catch jaws to grip the drill pipeand holding the drill pipe in place relative to the rotating unit or rotating the drill pipe.
    The power for this is obtained from a rotary motor 409, which is a part ofthe rotary unit. The rotary motor is driven hydraulically, for example, but othersapplications are also possible. The driving force for the rotary motor is obtained fromthe drilling rig and its power source. The rotation unit has a hole 411, through whichthe drill pipe passes through the rotation unit. The rotation unit is attached to the guide414. The guides are moved in the direction of the longitudinal axis ofthe bore beam boom 400 along sliding grooves 406 on the inner surface of the frame 408.
    The figure shows three sliding tracks, but their number can also be something else.
    The guide has advantageous sliding cushions to reduce the friction between the guide and101520253018the sliding track. The guide is built to be so robust that its shape or position does notsubstantially changes, for example, when lifting the drill pipe. The guide has a lower oneposition, being at the other end 412 of the bore beam boom, andan upper position, being at the first end 402 ofthe drilling beam boom. It should be noted that the guide is in its lower position in some casesmay be higher than in its upper position, for example when drilling obliquely upwards in amine. The guide is moved by applying a force to it with the drive means, whichis attached to the end of the guide, which is towards the first end ofthe drilling beam boom.
    The first drive means 404 and the second drive means 407 arehydraulic cylinders, which are elongated pipe-like structures and withcomponents that go together. The drive means are in the direction ofthe drilling beam boom. The first drive means has a first cylinder part 416and a second cylinder portion 403 of the first drive means. The otherthe drive means has a first cylinder part 417 and a second cylinder part 405 ofthe second drive means. In this example, the first cylinder part ofthe drive means a shaft, at the end of which a piston is located, and the other cylinder part isa cylinder. The first cylinder parts of the drive means go inside the othersthe cylinder parts. The ends of the first cylinder parts that are closerthe other end 412 of the bore beam boom is attached to the guide 414. Ithe end of the second cylinder parts into which the first cylinder parts go,or near the end in question, there is a fastening device 415, with which the otherthe cylinder part can be attached to the first end 402 in the frame 408 ofthe drilling beam boom. This fastener can be opened and closed. Thethere are also hydraulic cylinders, which have a shaft attached to both ends,along which a cylinder moves back and forth.
    At point a in Figure 4, the guide 414 is in its lower position, i.e. it isat the other end 412 of the drill beam boom. Fastening arrangement 415detached from the frame 408. The first cylinder parts are inside the othersthe cylinder parts. Thus, the stroke of the hydraulic cylinder is asis used as a drive means at its minimum, and the other cylinder parts are1015202519substantially inside the frame of the drill beam boom. This allows the drilling rigeasier to carry in transport condition, when the construction ofthe bore beam boom is shortened.
    At point b in Figure 4, the guide 414 is in its lower position andthe mounting arrangement 415 is attached to the frame 408 at the first end 402 ofthe drilling beam boom. Now the first cylinder parts are outside the othersthe cylinder parts. Thus the stroke is of the hydraulic cylinder whichused as a driving means at its maximum.
    At point c in Figure 4, the guide 414 is in its upper position andthe mounting arrangement 415 is attached to the frame 408 at the first end 402 ofthe drilling beam boom. Now the first cylinder parts are inside the othersthe cylinder parts. Thus, the stroke of the hydraulic cylinder is asused as a driving force at its minimum.
    When the guide is moved between the upper and lower position withdrive means, forces can be directed towards the drill pipe in the direction of the drilling beam boom.
    The drill pipe can be pushed down or it can be lifted. Stroke length ofthe drill beam boom is the distance that the drill pipe can be moved without looseningthe grip on the catch jaws on the drill pipe. That is, if the catchers have onegrip on the drill pipe and the guide is moved from the lower position to the upper position,is the stroke the moving distance of the guide between said positions. lFigure 4, the stroke can be said to be from the end of the guide 414, as in point bis towards the first end of the drill beam boom to the present point, wheresaid end of the guide is in its upper position according to point c. This is the caseaccording to the example near the surface of the fastening arrangement 415.
    Figure 5 shows an example of a drilling beam boom 500 in accordance withthe invention shown from above. This direction means that the drilling beam boomviewed from the direction of the opposite side of the lower surface ofthe drilling beam boom. The drill beam boom has a first end 512 and aother end 509 and a handling surface 515.101520253020The bore beam boom 500 has a frame 506, which frame has onebottom portion 516, which covers the lower surface of the bore beam boom. Ramenshall also cover the side surface of the drill beam boom, which is on the oppositethe side of the direction from which the drill beam boom and drill pipe areintended to be handled. In the example, the frame is formed by two plates and end parts,which is at the ends of the drill beam boom. The frame can also have anyother shape, for example, its cross-section may have the shape of a half-cup.
    The frame leaves the handling surface 515 open so that drill pipes and drill pipe segments canhandled on the drilling beam boom, such as laying in place andremoved. The bore beam boom has a rotation unit 508, which has onerotary motor 507. The rotary unit is in the guide 514. On the inner surface ofthe frame there is one or fl your sliding grooves for controlling the movements of the guideand to reduce friction. The drilling beam boom has drive means for fl surfacethe guide and at the same time the drill pipe is held in place by the rotation unit. In the example isdrive means a first hydraulic cylinder 502 and a second hydraulic cylinder511. The first hydraulic cylinder has a first cylinder part 504 and asecond cylinder part 501. The second hydraulic cylinder has a first cylinder part513 and a second cylinder part 510. Hydraulic pressures working insidethe hydraulic cylinders on that side of the shaft pull the first cylinder parts inside themthe other cylinder parts or the hydraulic pressures acting on that side ofthe piston pushes them out of it. The force directed by the drive means upwardsthe guide is in the direction of the longitudinal axis of the drilling beam boom.
    The other cylinder parts are attached by fasteners 503 at their ends theretothe first end of the drill beam boom to be immobile relative toramen. The other cylinder parts are thus substantially outside the structuresfor the drilling beam boom. The guide is in its lower position, with the firstthe cylinder parts are outside the other cylinder parts. Because the othersthe cylinder parts remain in place during use ofdrilling beam beams, they can be used as extension beam beams oras parts of them, whereby a separate extension beam boom is not needed indrilling rig.1015202521Figure 6 shows the drilling beam boom 500 according to Figure 5 examined fromside. The lower surface of the drilling beam boom is on the right in the figure. Thethe lower part 516 of the frame 506 covers the lower surface. Points a, b, c and dare marked in the figure, which illustrate the location of the corresponding onesthe parts in Figure 7. Points a and d are directions, from whichthe drilling beam boom is considered, and points b and c are cross-sectional points.
    Figure 7 shows the drilling beam boom according to Figure 5 viewed from thereends and as a cross section in two points.
    In Figure 7a, the other end of the bore beam boom 500 is viewedfrom the direction a according to figure 6. The other end of the drilling beam boom isprotected by the end structure of the frame 506, which has a mold 701 for the drill pipeand for service measures. The drill beam boom has a handling area of 515.
    Bore beam boom has a rotating unit 508, which gets its driving force from arotary motor 507. A hole 702 for the drill pipe passes through the rotary unit. INin the middle of the hole there is a pipeline, which is straight, in the direction of which the drill piperuns in the drilling beam boom. The pipeline is also significantly onthe center line of the drill pipe.
    Figure 7b shows a cross section of the bore beam boom 500 in point b iFigure 6 viewed from direction a. The frame 506 has a lower part 516 and aside part 704. The bottom part covers the lower surface of the drilling beam boom andthe side part covers the side surface of the drilling beam boom, which is on the oppositeside of the side of the drilling beam boom, in the direction from which the drill pipe is intendedto be handled in the drilling beam boom. The frame thus leaves the handling surface 515open. The inner surface of the frame has the slides 703 in the direction ofthe drilling beam boom. In the example, there are three sliding grooves and they are at the edgeson the frame and in the connection point between the bottom part and the side part. The guide514 slides along sliding tracks.
    Figure 7c shows a cross section of the drilling beam boom500 in point c iFigure 6, the direction d is examined. The figure shows the end of the guide 514 towards the first101520253022the end of the drill beam boom. In addition, the first hydraulic cylinder502 attached and the second hydraulic cylinder 511 and the first parts ofthese: the first part 504 of the first hydraulic cylinder and thefirst part 513 of the second hydraulic cylinder. The cylinders are attached, sothat a straight line between its midpoints runs substantially through the pipelineor close to it. Thus, the pipeline and centerline ofthe hydraulic cylinders, i.e. straight lines in the direction of the cylinders and drawnthrough their midpoints, a plane in the drill beam boom. When boththe cylinders direct an equal force on the guide and at the same time the drill pipe, and they areplaced symmetrically in relation to the pipeline, the moments are as they arecauses on the drilling beam boom of equal size but in opposite directions,whereby they cancel each other out. It should be noted that moments of this kindcan also be provided with drive means, the forces from which are of different magnitudesbut whose distance from the pipeline is at the same time different. These forcesand distance can be selected so that the moments caused by drive means on differentsides if the pipeline reconnects or at least compensateseach other. An embodiment can also be made, if there are more than two drive means.
    Thus, drive means can be evenly distributed on different sides of the pipeline or canthere are different numbers of drive means on different sides of the pipeline. It canfor example, there are two drive means on one side and one on the other side. Also inIn these cases, the forces and positions of the drive means are dimensioned so thatthe moments cancel each other out. The level is determined by the cylinder center lines andthe pipeline is inclined substantially in the direction from whichthe drill beam boom and drill pipe are intended to be handled. The firstthe hydraulic cylinder 502 is thus higher than the other hydraulicthe cylinder 511 relative to the bottom part 516, i.e. the firstthe hydraulic cylinder is further away from the bottom part than the otherhydraulic cylinder.
    In Figure 7d the first end of the drilling beam boom500 is examinedfrom the direction D in accordance with Figure 6. The first end ofthe bore beam boom is protected by the end structure of the frame 506, whichhas a mold 705 for the drill pipe. The second part 501 of the first101520253023the hydraulic cylinder 502 and the second part 510 of the second hydraulicthe cylinder 511 is fastened with fastening parts 503 to the frame.
    Figure 8 shows an example of a drilling beam boom according to the inventionviewed in the direction from its first end. The lower surface 808 ofthe drilling beam boom is downwards in the figure. Drilling beam boom has onedrill pipe channel 807, which runs through the drilling beam boom, and the drill pipe runsalong this channel. In the middle of the canal is the pipeline 801.
    The bore beam boom has a first drive member 805 and a second drive member802. The drive means are in the direction of the pipeline and a drive means straightruns through the midpoints of the drive means. The first drive means sets onefirst drive straight 806 and the second drive sets a seconddrive straight 803. The directions of said straight lines andthe pipeline is perpendicular to the plane of the figure. In accordance with the invention inthe example shown in the figure is the pipeline and the propulsion drive racks indrilling beam boom on the same plane 804. Each drive means, whendirecting a force on the guide of the drill beam boom, a moment M onthe drilling beam boom. The direction and size of this step depends onthe magnitude of the force caused by the drive means and the distance betweendrive straight and pipeline. In the example, drive means are locatedsymmetrically and the moments caused by them are equal but in oppositedirections. Thus, the moments are directed towards the drilling beam boom and those thatcaused by the drive means is counteracted. This shredding of torque forces onthe drive means can also be made with a different configuration than whatdescribed in this example. The essential thing is that the level 804 which is determined bythe drive line distance and the pipeline are divided by the pipeline and thetorques caused by drive means on different sides of the pipeline are of equalsize and in the opposite direction, that is, their intrinsic values are offsame size or close together.
    Figure 9 shows the drilling beam boom according to figure 8 viewed fromthe direction of the plane e marked in Figure 8. Forces acting onthe drilling beam bar is marked as an example in the figure. The figure shows it10152024force F1 caused by the first drive means 805 and the force F2 causedof the second drive means 802. In addition, the drill pipe itself has caused a forceF3, which is opposite to the forces caused by the drive means. Moments M1 andM2 caused by the current means are also marked as examples inthe figure. The first drive means causes the torque M1 and the seconddrive means torque M2. Due to the fact that drive means are mounted on differentsides of the pipeline, M1 and M2 are in opposite directions. Thus takesmoments out each other or at least compensate for each other's effects. Ifonly one drilling beam boom affected by drive means would torque asthereby causing bending and some elongation in the frame 808 and othersstructures from the drilling beam boom. With the arrangement according toAccording to the invention, the effect caused by the moments being counteracted.
    The invention can be used in particular in sampling drilling, sinceit is quite ambulatory and the devices must be small and lightexample compared to oil drilling, whereby it is useful forhandle the drill pipe at least partially manually. To gain better insight intothe drilling beam boom of course also makes machine handling of the drill pipelighter.
    Certain advantageous embodiments of the invention have been describedabove. The invention is not limited to the solutions described above, butthe inventive idea can be applied in many different ways within the framework ofpatent claims.
