    专利说明:

    The mine shown in Figure 1 comprises a shaft taken up in the bottom of the mine. The shaft is occupied to a depth corresponding to the range of conventional mining equipment. Adjacent to the edge of the shaft is a shaft suspension rack according to the invention. It comprises a conventional mobile crane which has been modified to meet the requirements of a shaft suspension rack. The mobile crane 1 comprises a mobile motorized crane chassis 2, also called a mobile crane. the crane chassis in this example according to figure 1 is provided with moving means 3 in the form of wheels, but in another embodiment can be provided with caterpillar feet. The mobile crane is powered by an internal combustion engine 4, usually a diesel engine. The mobile crane is operated during transport from a cab 5 with conventional equipment such as control panel 6, steering wheel 7, pedals 8, switch 9 and changeover device 10. The crane chassis further comprises support legs 11, advantageously a support leg in each corner. The support legs are arranged with support leg guards (not shown) in the form of sensors which indicate whether the support legs are extended and / or lowered. The support legs are actuated by means of hydraulic cylinders 12.
    These hydraulic cylinders are fed in a known manner with a hydraulic flow from a hydraulic pump (not shown) driven by the internal combustion engine.
    The crane chassis further comprises a hydraulically maneuverable crane arm 13 or boom. The crane arm 13 is mounted on a pivot plate 14 and is pivotable in the plane 15 of the chassis. The crane arm 13 is furthermore telescopic in a known manner, i.e. comprises a main part 16 and a extendable part 17 accommodated in the main part. The crane arm 13 is hingedly mounted to the pivot plate 14. height by means of hydraulic cylinders 18. In the outermost free end 19 of the crane arm 13, the tip, a breaking wheel 20 is arranged for guiding a wire 21. In connection with the breaking wheel 20 at least one overplay switch 22 is placed. The function of the overplay switch 22 will be described below. The movements of the crane arm 13 such as swinging, raising, lowering and projecting are regulated in a known manner in order to avoid the crane arm colliding with any other part of the mobile crane 1. In connection with the crane chassis 2 and the crane arm 13 a frame 23 is arranged with a main clearance 24. comprises a hydraulic pump 25 driven by an electric motor 26 and a line drum 27 which is driven by a hydraulic motor 28. On the line drum 27 said line or wire 21 is wound. The game 24 is further provided with a counter 29 which counts the number of rope turns wound on the drum 27. Furthermore, a counter 30 is arranged which counts the number of rope layers present on the drum 27. Finally, a speedometer 31 is provided which measures the speed at which the rope is wound off. and on the rope drum 27. The purpose of this is to prevent the rope or wire from being unwound completely from the drum during the work thread. The counters and hupwdms.Zacco.com/sites/se/case/4o1s1o1osc/41 1 00396 / P41 100396SE00 / P41 100396SEOO_201 1-02- 10 15 20 25 30 35 the meters 29, 30 and 31 are of a common type, for example optical, electrical or mechanical devices.
    At the free end 32 of the wire 21, a fastening device 33 is arranged for, for example, a lifting hook or a work platform 33a. To prevent the fastener 33 from being pulled over the breaker wheel 20, i.e. the wire 21 being wound too far, the overplay switch 22 breaks the current to the winch 24 as the fastener 33 approaches the overplay switch by means of a sensor 34 arranged on the wire 21 adjacent the fastener 33.
    Between the frame 23 and the winch 24 is arranged a meter 35 which measures moment of force or load moment between the stand and winch, the purpose of which is to avoid overload in the construction.
    The meter 35 may be in the form of a strain gauge or load sensor, which indicates strain or strain between the frame 23 and the winch 24.
    Arranged between the crane chassis 2 and the crane arm 13 is an angle sensor 36. The angle sensor 36 measures the angle between the crane arm 13 and the crane chassis 2, which angle is used for calculating the force to which the crane arm is subjected during the work.
    Arranged to the chassis 2 is a power transmission system comprising a hydraulic system 37 for delivering a pressurized hydraulic flow to the hydraulic consumers and its operation when the mobile crane is at its intended workplace. The hydraulic consumers and their maneuvering here refer to raising and lowering of the crane arm, extension or retraction of the telescopic part and rotation of the crane arm on the turntable. The hydraulic system 37 is driven by an electric motor 38 which drives a hydraulic pump 39 and pressurizes a fluid, which is fed via hoses and valves (not shown) to the hydraulic consumers. The hydraulic system is thus disconnected from the motor 4 which drives the mobile crane 1 during the operation of the mobile crane 1 up to the workplace.
    To activate the hydraulic system 37 and the winch 24, an electrical cabinet 40 of the mobile crane 1 is connected to the mine's electrical network, for example 400 V. The connection is made with a multi-pole connector 41 or cable glove to the electrical cabinet 40, from where power is routed to designated parts. In this way, the parts and functions of the mobile crane can be controlled and operated at the workplace inside the mine without emitting exhaust fumes.
    Said control and operation takes place by means of a control panel 42 shown in figure 2. The control panel is separate from the control panel 6 which is located inside the driver's cab 5.
    The control panel 42 includes controls 43 for operating the game 24 and the crane arm 13. http://dms.zacco.com/sites/se/Casel40131010SC/fi-1 100396 / P41 10Û39ÖSEÛO / P41 100396SEOÜ_2Û1 1-02- 10 15 20 25 30 35 4 The control panel 42 is in signal connection with the mobile crane 1 via wireless signals 44, for example radio signals, sound or light signals. But it should be understood that the signal transmission can also take place via a cable. The advantage of wireless connection is that the control panel 42 can be placed in the work platform 33a or basket to be lowered into the shaft. In this way, personnel who are in the basket down in the shaft can maneuver the basket with good precision.
    Arranged for the crane arm 13 is a rescue game 45 with a rope drum 46. By rescue game is meant here a game similar to the main game 24 described above but which is dimensioned to only handle loads from a basket with space for one or more persons without equipment.
    The purpose of the rescue game 45 is to be able to quickly rescue personnel who are in a shaft without having to move the mobile crane 1. The rescue game 45 is placed on the crane arm 13 in front of the crane chassis 2 front, and equipped with gauges 47 for number of ropes, ropes and speed. From the rescue game 45 a rescue cable 48 runs over a break wheel 49 arranged in connection with the tip 19 of the crane arm 13.
    A control cable 50 runs from the rescue spindle 45 in the direction of the tip 19 of the crane arm, and has a throwing block 51. In connection with the throwing block 51 a play switch 52 is arranged. rescue basket 53 hanging down. By adjusting the length of the control cable 50, the rescue basket 53 can be moved in the direction of the crane arm 13, away from or in the direction of the chassis 2. In this way, the rescue basket 53 can be maneuvered into a shaft X and past obstacles that may be in the shaft to reach distressed staff.
    The rescue game includes a hydraulic motor 54 which drives a rope drum 55. The hydraulic motor can be driven by the same hydraulic system as the support legs 11. This gives the advantage that if a power failure occurs in the mine, personnel in a shaft can be easily retrieved. The rescue game is operated from a separate control panel 56 which can be seen in figure 2, or from the control panel 6 in the mobile crane's cab 5.
    It should be understood that the mobile shaft suspension stand or mobile crane 1 can be used with a number of different baskets or work platforms. before use, the mobile crane is inspected together with the baskets or platforms that may be used, for example of different sizes, and when this inspection is carried out, a certain period of time runs before the next inspection, usually one year. However, this time period may differ between the laws of different countries. When the inspection is complete and approved, the mobile shaft stand can be used. nupu / dms .: acw.com/sltes/se/case/4o131o1osc/41 100396 / P41 100396SEOO / P41 100396SEOO_201 1-02- 10 15 20 25 30 35 When the mobile shaft suspension stand or mobile crane 1 is moved to the shaft X, it is driven by means of its internal combustion engine 4. When it has been maneuvered to the intended place, the support legs 11 are folded out and maneuvered to a horizontal position, as shown in figure 3. In this case, a signal is given to the control panel 42 to indicate that the support legs 11 are extended. In this position the internal combustion engine 4 is switched off and a power cable (not shown) from the mine's electricity network is connected to the electrical cabinet's contact 41. When this happens, the mobile crane 1's ordinary hydraulic system is disconnected, ie the hydraulic system fed by a hydraulic flow from a hydraulic pump driven by the internal combustion engine 4. In its place, the electric hydraulic system 37 is engaged. An operator holds the control panel 42 with which the functions of the mobile shaft suspension stand 1 can be controlled. On the control panel 42 it is indicated whether the support legs 11 are extended. With the aid of the various control levers of a common type, for example joysticks and / or knobs, the crane arm 13 can be swung, pushed in or out and raised or lowered. Furthermore, the rotation of the game 24 can be regulated, ie at what speed the drum 27 is to be rotated and the amount of line or wire to be fed out or in.
    The operator maneuvers the work platform 33a or the basket to the floor F of the mine. Then the equipment (not shown) to be used is placed down in the shaft of the platform, after which the staff (not shown) and the operator (not shown) step up on the platform 33a. Then the operator lifts the platform 33a from the floor, pivots the crane arm 13 so that the platform ends up in a position over the shaft X. When the desired position is reached, the operator maneuvers the rotation of the game drum 27 via the control panel 42 whereby the platform 33a is lowered into the shaft X.
    Since the operator is on the platform, the platform can be operated with great precision. It should be understood that the operator may also remain on the floor of the mine during the operation. Once the platform is placed at the bottom of the shaft, work down the shaft can begin. Advantageously, the platform can be hoisted up while the work is going on down in the shaft, so as not to take up space.
    When the excavation work, which includes drilling and deployment of explosives but may also include scrapping, removal of loose rock or cleaning work, is completed, the platform is hoisted down and equipment and personnel are loaded on the platform, Platform 33a is hoisted up and staff disembark. Then the power cable (not shown) is disconnected, and the internal combustion engine 4 is started. The support legs 11 are folded in, after which the mobile shaft suspension stand 1 is driven away from the shaft X. When it is at a proper distance from the shaft together with personnel and equipment, the blasting is carried out.
    Since all equipment has been removed, the risk of damage to it has also been eliminated. Thereafter, the mobile shaft suspension stand is set up again according to the previously described method, and the shaft receiving work is carried out again. http: mims .: acw.com/sires/se/casemo131o1osc/41 100396 / P41 100396SE00 / P41 1 OO396SEO0_201 1-02-, _ _ | _ ll_L_J __! J __L_ | 4_u_ | __! ____ J, ___ 10 15 20 This method involves significant time savings and is economically efficient. It should be understood that a mobile shaft suspension rack of the type described above can be used for two or more shafts. This means that when personnel and equipment have been lowered into a first shaft, the shaft suspension rack can be moved to a second shaft and lower additional personnel and equipment into this shaft and thus alternate between different shafts. It should be understood here that considerable savings can be made, in that a single mobile shaft suspension stand can be used for several shafts simultaneously. In the event that the platform becomes unusable, for example due to a power outage in the mine's electricity network, or due to it getting stuck in the shaft, the rescue equipment can be used. Rescue equipment here refers to the rescue basket 53 described above, the control panel 59 and the rescue game 45. If the platform 33a is stuck, the mobile shaft suspension stand 1 cannot be moved. The operator changes the control panel to the rescue equipment control panel 59, and starts the internal combustion engine 4 if a power failure has occurred. Then, if necessary, he maneuvers the rescue basket 53 laterally by turning the crane arm 13, and adjusts the distance between the rescue basket 53 and the edge X of the shaft. This is done by lengthening or shortening the control wire 50. By such an adjustment, the throwing block 51 is moved over which the rescue cable 48 runs, whereby the rescue cable 48 and thus the rescue basket 53 can be adjusted in vertical direction. When the desired position is reached, the rescue basket 53 is lowered into the shaft X. During the downward movement of the basket, further position adjustments can be made. The rescue basket 53 is lowered to the level of the emergency personnel so that the personnel can step into the rescue basket 53, after which it is hoisted up. In this way, personnel can be picked up from shaft X in the event of an accident, for example if the platform is stuck or the game has crashed, or if a power failure has occurred.
    The present invention is not limited to the one described above and shown in the drawings, but can be changed and modified in a number of different ways within the scope of the inventive concept stated in the appended claims. mip: fl dms.zacwßom / sites / se / case / ßto131o1osc / 41 100396 / P41 100396SEO0 / P41 100396SE00_201 1-02- A fi LAÅI- HÅÅL-J ..l..l _._ l__l-. | -_L '_._ | -. ^!. ^ ~ .J - u
