    FIELD OF THE INVENTION The invention relates to a handling device for handling drill string components in a rock drilling rig. The handling device comprises a magazine for storing drill string components, which are to be inserted into or removed from a drilling rig for the rock drilling rig. The magazine comprises support means for support of a plurality of rollable drill string components, which support means are tiltable for inclination towards and from a loading layer, from which individual drill string components are intended to be transferred to the said drill string layer. The invention also relates to a rock drilling rig equipped with such a handling device.
    BACKGROUND OF THE INVENTION Core drilling for exploration purposes is usually performed with rock drilling rigs, in which the drill string components are placed in the active drilling rig, lifted out of each sink into the drill tail with the aid of a winch. The winch wire is fixed in the lowest drill string component by means of a lifting plug. Since core drilling aims to occupy a drilled core of rock to be investigated, it is a question of rudder-shaped drill string components. When picking up the pipe string, which takes place frequently when changing drill bits, the pipe string is lifted up in a unitary manner, whereby the individual pipes are pulled apart from each other by means of the rock drilling rig's rotator device in cooperation with a lower pipe holder.
    Final unloading of a pipe to be removed from the pipe string is currently done at least partly by hand by the operators, this bundling comprising final departure and lifting and steering of the pipe to the area of a pipe magazine. 2 When lowering the drill string, the work steps are performed in the reverse order so that new drill string components in the form of pipes are gradually lifted to a low point where they are aligned with the drill string and assembled by the operator. These operations are burdensome for the operator and entail a non-negligible risk of lifting and squeezing injuries for the operator.
    Core drilling often takes place at very great depths, such as for drilling lengths between 1,000 - 2,000 m. Due to the fact that the drill bit in operation is subject to wear, it needs to be replaced relatively often, which means that the entire drilling line must be picked up from the drill tail. disassembled into drill string components, the worn drill bit is removed and replaced with a new one, after which the drill string can be lowered into the tail. Then drill another line until the drill bit has to be replaced, etc. In the actual drilling, a rinsing fluid swivel is connected to the end of the drilling line to provide rinsing liquid for transporting away rock material loosened by the drilling.
    OBJECTS AND MOST IMPORTANT CHARACTERISTICS OF THE INVENTION It is an object of the invention to provide a device of the above-mentioned type, in which the handling of drilling rig components is at least partially improved. This is achieved in a handling device according to the above in that the magazine, in the area of the loading bed, comprises a transfer unit for separating a drilling component present on the said support member from an adjacent drilling component, for transferring the separated drilling component to the loading component to the loading device. the magazine that the transfer unit comprises movable stop elements for arranging said separation, that the transfer unit comprises a plurality of longitudinal axial directions of a rotating arm component distributed in the loading layer, engages rotating arms with a drill string component circumferentially axially circumferential axis ldge, in which the pivot arms abut against a drill string component present closest to the loading layer on the said support means, to a second layer, in which the pivot arms have agreed to lower the separated drill string component one to the loading team.
    This ensures things and the necessary separation of a drill string component intended for entry into the rig, as well as things positioning thereof in the loading layer. This loading ledge is arranged laterally in relation to the city members of the magazine. By providing the pivoting unit (pivotable) rotary arms, the possibility of simple maneuvering and with simple means a secure and precision manufacturable construction is achieved.
    Providing stop elements, ensures proper separation as well as prevents drill string components, which should continue to rest on. the support members, accidentally move in the area of the loading layer during the sawing phase when the drill string is removed from when it is inserted into the drill bit.
    The transfer unit according to the invention is also arranged to transfer a drilling line component from the loading layer to the magazine, the transfer process in principle being driven in the opposite direction.
    It is preferred that each pivot arm is connected to a set of stop elements, which allows for easy maneuvering. In particular, it is preferred that each set of stop elements is articulated with and supported by the respective pivot arm for limited inboard movement about an axis parallel to said pivot axis.
    Furthermore, it is preferred that the movement for a respective set of stop elements is adjustable for adaptation to 4 drill string components with different diameters, which per simple adaptation when changing dimensions. In particular, it is required that the movement of the respective set of stop elements is adjustable in that adjustable guide projections cooperating with stop elements are provided along the longitudinal path of movement of the said stop elements.
    It is advisable for each pivot arm to have a stop surface, which is designed to obsolete a drill string component in an upward movement during the movement of the pivot arm from the second joint to the first joint. An undamaged movement in the vertical direction is facilitated dd.
    The hopper has the magazine a support frame, on which said support members are hingedly mounted in the area of the loading bed to allow adjustment of the inclination.
    It is also preferred that the support frame comprises the fastening for the pivot arms in connection with the fastening for city units entering the support means, which facilitates the design of the construction in terms of stability.
    It is conceivable that each support unit in a domed opposite loading load is supported by an adjustable city leg for adaptation to hi. a. ojdmnt substrate.
    Preferably, each support unit in an enclosed space opposite the loading floor is provided with a power device for arranging for the adjustment of inclination of said abutment means. A normal position of the support members is preferably the inclination of the loading element and with the actuator activated the inclination towards the loading element.
    Preferably, in the handling device there is a swing arm, which has means for receiving a drill string component in the loading bed, and which is pivotable between the loading floor and a drainage floor for the rock drilling rig. The pivot arm of the handling device ensures that a supported drill string component is pivoted from the loading layer for drill string components, which typically carries a horizontal beam, to the said discharge beam, which is usually a sloping shaft for the supported drill string. The swing arm is suitably supported pivotably by the magazine, which is component-saving and provides good stability. The pivot arm Or is mounted laterally in relation to the firing unit and the rotary arms to allow its vertical movement without it interfering with them. It is possible, for example, to design the swing arm with its city elements forming a "gutter" for supporting a drill string component with lateral recesses to allow passage of the rotary arms. Other construction solutions Or of course also possible.
    The reverse procedure to what is stated above is current in which drill string components are taken out of the drill tail and taken out of the rig. The drill string components are laid in the loading layer and passed through the rotary arms up onto the support members, which are adjusted for inclination from the loading layer.
    In order to ensure in an efficient and safe manner an accurate alignment between the gripper unit and the drill string component supported by the pivot arm, a alignment beam is suitably provided, which is arranged to form a mechanical stop for both a pivotable gripper unit mounted on the rig and the pivot arm. For this purpose, the directional beam is suitably hingedly attached to its dome domains.
    The invention also relates to a rock drilling rig, including a rotating device intended for rotation and drive of a drilling rig, supported by a feed beam, and a handling device as above.
    The invention will now be described in more detail with reference to exemplary embodiments and with reference to the accompanying drawings.
    BRIEF DESCRIPTION OF THE DRAWINGS 6 Fig. 1 shows in a side view a rock drilling rig for core drilling provided with a handling device according to the invention and in connection with a magazine for drilling rig components, Fig. 2 shows in a perspective view a detail of the magazine according to the invention, and Fig. 3 and 4 shows side views of a detail of the magazine according to the invention in different layers.
    DESCRIPTION OF EMBODIMENT EXAMPLE 1 Fig. 1 shows a feed beam 2 which can be installed with varying inclination angle for a rock drilling rig for core drilling. The rig includes a rotator device 4 which is supported forwards and backwards on the feed beam 2. Below (in the picture) the rotator device 4 a pipe holder 5 is arranged for temporary holding of the drill string dl as necessary.
    Adjacent to the feed beam 2 is a power and drive unit (not shown) for supplying pressure fluid etc. to the rock drilling rig and a lifting winch (not shown). A magazine 6 is arranged to receive drill string components (indicated by a dotted line at 8), which are to be inserted into or picked up from the rock drilling rig in a manner which will be described below.
    The magazine 6 is shown in Fig. 1 in the form of a substantially horizontal structure, which is inclined so that drill string components 8 can be made to roll against a swing arm 7 arranged for receiving a drill string component 8. An experience unit provides experience of a separated drill string loading ledge, which is defined by the pivot arm 7. By 42, pivot arms are indicated by the entry into the transfer unit. The rotary arms and Other components in the magazine are described in more detail below.
    P1 Fig. 1 is further indicated by a dashed line at 8 "a drill string component in a bearing during a 7 lifting phase, which is a sloping bearing in relation to the feed beam 2.
    This line at 8 "in Fig. 1 is intended to illustrate an intermediate layer during the lifting phase, which ends with the drill string component occupying a layer which is coaxial with an active drill string bearing of the rock drilling rig. Lifting takes place by means of a lifting plug inserted at the top of the drill string component 8" (25 see below). During this process, the lifting plug is in turn connected to a lifting wire (not shown), which in turn also runs a wire pulley (not shown) at the top of the feed beam and with its other part farlaps substantially parallel to the feed beam 2 to the one in the area of force and the drive unit 3 aligned the lifting winch (not shown).
    Furthermore, Fig. 1 shows a lifting plug gripped by a gripper unit 11 and fastened to a duct portion of a drill string component 8 'present in a drill string type.
    Fig. 1 further shows that said end portion protrudes from the rotator device 4 so that this drill string component 8 'is in an active drill string type A. The drill string component 8' has a female thread for engagement with a corresponding male thread on the plug 25.
    Matching of a further, second, drill string component 8 "on the first drill string component 8 'in the event of a demand of the drill string is subsequently immersed in the drill tail, substantially in accordance with the procedure for packing a lifting plug. See below.
    The gripper unit 11 is shown in a first layer in Fig. 1, in which a gripping bearing defined by the gripper unit 11, which has a gripping bearing shaft G (see dashed line in Fig. 1), is coaxial with said active drill string bearing A.
    Furthermore, a guide beam 19 is shown in more detail in this figure, which is arranged to constitute a stop for the pivot arm 7 in a suspended lamination layer for a supported drill string component 8. In addition, the guide beam 198 constitutes a stop for the gripper unit 11 in the second member thereof. Support elements forming a "rudder" for supporting a drill string component are indicated by 7.
    The gripper unit 11 is not dangerous for the present invention and is therefore not described in more detail here.
    After mounting an additional drill string component to a hole on top of an existing one in hole A (in place of the lifting plug 25 in Fig. 1), the drill string components are pulled together by the rotating means, after which the joint is usually terminated by the rotator device 4. Then the drill string can be lifted. slacks. (Of course, fitting is done in the same way when the drill string is lowered by drilling.) Then the drill string is lowered down to the layer shown in Fig. 1, the next drill string component being the layer indicated by 8 'with a duct protruding from the rotator device 4 and with the lifting plug 25 sitting on top of this drill string component. This lifting plug must now be pulled off the drill string.
    The lifting plug 25 is formed by a swivel device and therefore has two inwardly rotatable parts, namely an engaging part, which at the bottom is fitted with a hanger on its free end, facing the drill string component and a lifting part, which is ultimately fitted with a lifting wire. described above.
    When the lifting plug 25 is pulled loose from the drill string component 8 '(Fig. 1), the gripper unit 11 is pivoted from the first layer in the direction of said second layer with the hall lifting plug 25 to the second layer where the gripping layer Or aligned for cooperation with a drill string component 8 supported by the link arm 7 is connected. to said magazine 6. This certain length of the gripper unit 11 is supplied by the alignment beam 19 forming a mechanical stop for the pivoting movement of the gripper unit 11 in said second layer. 9 Here, the engaging part is inserted into the drill string component 8 and then it is released to be lifted with the aid of the lifting wire so that it later ends up in the barrel, the second drill string component along the "grip shaft" is indicated by G in Fig. 1.
    Before the drilling rig component 8 is lifted, it has been gripped in the area of the second end, opposite the end which is joined by a lifting plug, by a guide gripper attached to a gripper carriage 40 at a joint, which is operated by a hydraulic cylinder. Then the swingarm 7 is lowered to the loading bed (in Fig. 1) when it is out of the way of the movement of the gripper carriage 40.
    The alignment beam 19 has a longitudinal guide for the drivably movable gripper carriage 40. The hinge has a hinge axis substantially parallel to the first and second pivot shafts A1 and A2 for allowing pivoting in the same plane which occupies the drilling strut floor and the drainage floor.
    The gripper is designed to, after gripping the said drill string component 8, control the free end drive shaft to control its movement during the lifting process and is allowed to steer this free end into alignment with the drill string lead A in the rig. When the guide gripper is activated, gripping a drilling rig component and the running gripper carriage, it is arranged so that the guide gripper follows the rotary movement without being rotationally controlled separately. so far the operative function of the handling device according to the invention in immersing a drill string after, for example, replacing a drill bit has been described. When picking up the drill string, in principle the opposite procedure takes place, namely fastening of the lifting plug to a drill string component located in the active drill string, pulling up the lifting plug with adhering drill string to a length when the rotator device is pulled in and out. the drilling rig component from the subsequent drilling rig component.
    Thereafter, the drill string Si is further lifted so that the next drill string component with its end portion ends up in the same as shown in Fig. 1, after which the gripper unit 11 enters and grips the lowest drill string component and also the second drill string component in the "first connection"). controlled loosening of the 5th top drill string component.
    Thereafter, the thus detached drill string component is gripped by said guide gripper and is driven by the movement of the gripper carriage 40 away from the feed beam 2 out from the ledge parallel to the active drill string layer with its lower end, while the lifting wire is slackened in a controlled manner so that the drill string component slams. Ear and the lifting plug di can be gripped by the grippers of the gripper unit 11 for discharging the latter. Lifting of the swing arm 7 for receiving the drilling string component now takes place, and when the exit is completed, the swing arm can be lowered to remove the supported drilling string component to the loading bed so that it can be transferred to the magazine 6 for storage by the transfer unit. Then the process can be repeated as many ginger as is necessary.
    The magazine according to the invention will now be described in more detail with reference to Figures 2, 3 and 4. As can be seen from these figures, the magazine 6 shows storage of drill string components 8, which are to be inserted into the respective tram drilling rig, city 44 and city means 44 'for standing of a plurality of rollable drill string components 8.
    These support members 44 'are inclined to be inclined towards the respective front of a loading ledge L, from which the drill string components are then moved to be transferred to the drill string stroke. The magazine comprises a transfer unit 41 in the area of the loading layer L, which transfer unit is arranged to separate the drill string component located closest to the loading layer from adjacent drill string components and arrange for the transfer of the separated drill string component to the loading layer L.
    For this purpose, the transfer unit has a plurality of rotary arms 42 distributed along a shaft direction R (see Fig. 1) of a drill string component 8 present in the loading layer L.
    These pivot arms are pivotable about an axis of rotation V, which is parallel to said axis direction, and driven by respective hydraulic cylinders 56.
    The pivot arms are pivotable from a first layer, as shown in Fig. 3, in which the pivot arms with a stop surface abut against a nearest drill layer L on said support member 44 existing drill string component 8. The pivot arms 42 are pivotable from this first layer to a second layer, as shown in Fig. 4, and in which the pivot arms 42 exposed the loading layer L and allowed the lowering of the separated drill string component 8 in this loading layer L.
    Furthermore, the pivot arms 42 carried a set of stop members 47 in articulated relationship for limited inboard movement relative to the respective pivot arm about an axis 43. It may be mentioned that by "set of stop members" is meant one or more stop members associated with the pivot arm. In the exemplary embodiment shown, the rotary arm is in principle formed by two parallel, spaced-apart plates with spacers between them and the number of stop elements 47 Or two.
    In order to adapt the magazine to drill string components with different diameters (different thicknesses), which can be handled by the rig, the movement of each set of stop elements 47 can be adjusted by adjusting guide projections cooperating with stop elements along the path of movement for each stop element. This can in practice be realized so that a guide projection, against which an edge of the stop element abuts, is adjustable for influencing the path of movement of the respective stop element. An example of such an adjustable guide projection is indicated by a broken line at 55 in Fig. 4.
    An example of the adjustability is through a handle 54 (Fig. 2), which is connected to the said guide projections via a rod, and through which the guide projection 55 thus has the respective stop element adjustable in a longitudinal direction S of the support member 44 '. Ideally, the stop element is spring-loaded in the direction of the loading layer L and controlled in a manner which counteracts this spring load.
    A city frame for the magazine is designated 46, and on it the said support means 44 are hingedly arranged in the area of the loading layer L to allow installation of the tiltability. The city frame 46 comprises the fasteners 49, 50 partly for the pivot arms 42, partly for support units 51 including a respective fixed stand 44, which slopes from the loading bed L, and the respective support member 44 ', which is hinged at the foot 50 and can be tilted towards the loading bed L. Fasteners 49 and 50 are arranged in connection with each other for, among other things, stability shields and also enhance the manufacturing ease of construction.
    Each support unit 51 is supported in a dunnage area opposite the loading layer L by an installable city leg 52, and in this domdom area the usual city unit is provided with a power device 53 in the form of, for example, a hydraulic cylinder for adjusting the inclination of the said city means 44 '. It can be mentioned that the slope can be installable so that a varying degree of slope can be obtained depending on, among other things, the type of drilling rig components that are handled. Feeding of a drill string component, which is in the loading layer L to the magazine, takes place through the supply unit from the layer shown in Fig. 4 by rotating the rotary arm, clockwise in Fig. 4, so that the drill string component 8 is lifted up by the impact surface 45 the city means 44 ', which are angled so as to be inclined from the loading ledge.
    The invention has been described in the light of a rock drilling rig for core drilling, but it is also applicable to other types of rigs such as those for oil drilling and the like.
    The invention can be modified within the scope of the claims. The magazine may be associated with a rock drilling rig in other ways than by a swing arm, as illustrated above. Thus, drill string components can be deposited between the rig and the loading bed by other means. The magazine can be adapted to drill string components of different lengths, and as an example a magazine with three rotary arms intended for drill string components with a length of 6 meters can also be used for drill string components with a length of 3 meters, in the latter case only two of the rotary arms are used.
    In its simplest form, the magazine is adapted for manual maneuvering, whereby an operator decides when different sequences are to be performed adapted to the needs of the rig. However, it is not excluded that the operation takes place automatically with the aid of a computerized control system or the like. This automation leads you to controlled collaboration between the magazine and the rig.
    The alignment beam can in a simplified form of the handling device according to the invention also be set up completely independent of the feed beam and the rig. Also in this form, it can be possible for the gripper carriage to fulfill its main tasks: to guide a lower end of a drill string component lifted in a lifting wire during the process of supplying a drill string component to the drill string and finally inserting it into a drill string type, to extend a drill string. one in a drill string type, of a drill string component raised in a lifting wire, from the drill string assembly and guiding the lower end during the process 14 of picking a drill string component from the drill string and finally placing the drill string component on a magazine or dill.
