Description

Technical Field

[0001] The invention relates to the technical field of hydraulic supports, in particular to a hydraulic support support structure for mining. Background Art

[0002] A mining hydraulic support is a support device specially used for mining working faces in mines. It is mainly used to control the pressure of coal mining working faces, support the roof of the mine, maintain a safe working space, and push the mining and transportation equipment on the working face. In the prior art, when moving the hydraulic support, it is necessary to first retract the support rod of the hydraulic cylinder so that the top beam is a certain distance away from the roof of the mine, and then stop lowering the column and use the "rubbing top moving frame" or "pressurized moving frame" method. The hydraulic support is lifted by a jack and then pushed horizontally onto the translation rail car. The rail car is used to drive the hydraulic support to move horizontally. After it is moved into place, it is unloaded from the translation rail car, and the hydraulic cylinder is driven to drive the support rod to lift the top beam again to support the roof of the destination. However, the above operations are relatively complicated, especially the process of getting on and off the rail car, which requires precise coordination and is difficult to operate. In addition, since the top beam adopts the "rubbing top and moving frame" moving method, the distance between it and the mine roof is relatively close during the movement, and the falling distance of the broken rock is relatively small, the top beam is not easily affected by the severe impact of the falling rock. However, during the use of the protective beam, although the protective beam is supported by the bracket, the large distance of the rock on the collapsed top plate causes a large impact force, which can easily cause damage to the protective beam.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a moving mechanism and a supporting mechanism, the operation of the second hydraulic cylinder drives the displacement plate to slide in the displacement groove, the displacement of the displacement plate drives the supporting column to move, the displacement of the supporting column lifts the base, so as to facilitate the lifting operation of the hydraulic support; the rotation of the rotating block drives the rotation of the first threaded rod, the rotation of the first threaded rod drives the cross plate to move, the displacement of the cross plate drives the fixed block to move through the connecting column, the fixed block moves out of the fixed groove, and the fixation of the movable seat is cancelled during the lifting operation, and the movable seat is pushed to slide in the movable groove, and the movable seat displacement drives the roller to move through the mounting rod, so as to facilitate the roller to match the height of the rail car or the preset movable rail, and the hydraulic support is moved by the roller, and the roller can be stored during the operation of the device.

[0017] 2. By setting up a protective mechanism, the protective plate is placed on the outer wall of the protective beam, and then the rotating plate is rotated, and the rotating plate rotates into the groove, and then the rotating column is rotated, and the rotation of the rotating column drives the second threaded rod to rotate, and the rotation of the second threaded rod drives the plug block to move, and the plug block moves into the groove and is inserted into the slot, so that the protective plate is fixed and installed, which is convenient for rapid installation and disassembly of the protective plate, and the outer wall of the protective beam is protected by the protective plate.

[0018] 3. By setting up an auxiliary support mechanism, when the device is in a supporting state, as the base is in a jacking state, the front beam and the top beam can be synchronously driven to be in a horizontal coplanar state. That is, when performing support operations, the front beam is driven to an expanded support state through the linkage action of the auxiliary support mechanism and the support mechanism, thereby supporting and protecting the top of the mine tunnel.

At the same time, the third hydraulic cylinder will return to the vertical state. At this time, the overall movement of the device is carried out, and the front beam is not easy to rub and collide with the top wall of the mine tunnel, which plays a good storage and protection role.

Fixed grooves 706 are symmetrically opened on both sides of the inner wall of the movable groove 702. The inside of the movable seat 703 is symmetrically slidably connected with a fixed block 707 extending from the movable seat 703. One end of the fixed block 707 located inside the movable seat 703 is rotatably connected to a connecting column 708, and one end of the connecting column 708 is rotatably connected to a cross plate 709. The inside of the movable seat 703 is rotatably connected to a first threaded rod 710 that passes through the cross plate 709. The top of the first threaded rod 710 is located at the top of the movable seat 703 and is fixedly connected to a rotating block 711. The position of the movable seat 703 is reinforced by a supporting mechanism 8, and the shielding beam 5 is protected by a protective mechanism 9.

[0032] In this embodiment: when adjusting the height of the roller 705, the rotating block 711 is rotated, and the rotating block 711 rotates to drive the first threaded rod 710 to rotate, and the first threaded rod 710 rotates to drive the cross plate 709 to move, and the displacement of the cross plate 709 drives the fixed block 707 to move through the connecting column 708, and the fixed block 707 moves out of the fixed groove 706, cancels the fixation of the movable seat 703, and pushes the movable seat 703 to slide in the movable groove 702, and the displacement of the movable seat 703 drives the roller 705 to move through the mounting rod 704.

[0033] Please refer to Figures 4 to 5 The supporting mechanism 8 includes a reinforcement groove 801, which is provided on the outer wall of the movable seat 703, and a displacement groove 805 is provided inside the base 1. The inner wall of the displacement groove 805 is slidably connected with a displacement plate 803, and the bottom end of the displacement plate 803 is fixedly connected with a support column 804 extending to the bottom end of the base 1. A second hydraulic cylinder 802 is installed on the top of the base 1, and the displacement plate 803 is connected to the output end of the second hydraulic cylinder 802.

The displacement of the pushing frame 808 drives the reinforcement block 810 to be inserted into the reinforcement groove 801, and the position of the movable seat 703 is reinforced to prevent the movable seat 703 from loosening during the use of the roller 705.

[0036] This design facilitates the movement of the hydraulic support via the rollers 705, and during the operation of the device, the rollers 705 can be stored.

[0049] Please refer to Figure 6 to Figure 7An auxiliary support mechanism 10 is arranged between the base 1 and the front beam 4. The auxiliary support mechanism 10 includes a rotating seat 1001 fixedly mounted on the upper surface of the base 1. The upper end of the rotating seat 1001 is rotatably connected to a third hydraulic cylinder 1004 through an axle. The axle is fixedly connected to a fixed end of the third hydraulic cylinder 1004, and the axle is rotatably connected to the rotating seat 1001. The outer end of the shaft is fixedly connected to a gear 1002, and a limiting member 1003 is arranged on one side of the gear 1002. The limiting member 1003 is a long strip structure, and a tooth stripe is arranged on the upper end of the limiting member 1003. The lower end of the limiting member 1003 passes through the outer wall of the base 1 and is fixedly connected to the top of the displacement plate 803. The output end of the third hydraulic cylinder 1004 is rotatably connected to a connecting rod 1005, and one end of the connecting rod 1005 is rotatably connected to the middle part of the rotating end of the front beam 4; a movable groove for the limiting member 1003 to move up and down is opened on the upper surface of the base 1. When the displacement plate 803 drives the limiting member 1003 to move downward, the tooth stripe on the upper end of the limiting member 1003 meshes with the gear 1002 for transmission.

[0050] In this embodiment, when support work is required, the second hydraulic cylinder 802 can also be used to drive the displacement plate 803 to slide in the displacement groove 805. The displacement of the displacement plate 803 drives the support column 804 to move. The displacement of the support column 804 lifts up the base 1. At the same time, the limiter 1003 will also be driven by the displacement plate 803 to move downward. The tooth stripes on the upper end of the limiter 1003 will contact the gear 1002 and drive the gear 1002 to rotate. The rotating gear 1002 will drive the driving end of the third hydraulic cylinder 1004 to tilt and move through the shaft (it should be noted that the third hydraulic cylinder 1004 is in a straight line with the base 1 in the initial stage). When the front beam 4 and the top beam 3 are in a relatively vertical state, and the front beam 4 and the top beam 3 are in a folded state, the driving end of the third hydraulic cylinder 1004 will push the connecting rod 1005 to move during the tilting process, and force the front beam 4 to rotate until the front beam 4 and the top beam 3 are in a horizontal coplanar state (at the same time, the support column 804 also completely lifts the base 1). At this time, it is only necessary to keep the third hydraulic cylinder 1004 and the limit member 1003 fixed, and the connecting rod 1005 and the front beam 4 will also be fixed by the restriction. Then, when performing support operations, the front beam 4 is driven to the unfolded support state through the linkage action of the auxiliary support mechanism 10 and the support mechanism 8, so as to support and protect the top of the mine tunnel.

[0051] When no support operation is performed, the displacement plate 803 is driven upward and returned to its original position by the second hydraulic cylinder 802. At this time, the limit member 1003 will also be lifted up, and the front beam 4 will also be pulled downward and flipped to be vertical with the top beam 3. The third hydraulic cylinder 1004 will return to the vertical state at the same time.

[0052] It should be noted that when it is necessary to lower the position height of the top beam 3, by driving the first hydraulic cylinder 2 to contract and at the same time driving the third hydraulic cylinder 1004 to contract, and then adjusting the position height of the top beam 3, the auxiliary support mechanism 10 will not cause any interference to its movement, and can ensure that the entire support structure can work normally.

[0053] What has been described above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the protection scope of the present invention.
