Description

Technical Field

[0002] With the continuous exploitation of coal resources, the occurrence of shallow coal seams has been greatly reduced, and coal mining has gradually moved deeper. The deepening of mining depth makes the geostress characteristics, surrounding rock stress state, coal body stress level, occurrence environment and other aspects of the coal seam particularly complex, and the frequency and intensity of rock bursts have also increased. When rock bursts occur, the elastic deformation energy accumulated in the rock mass is suddenly and violently released, and the rock bursts to produce a strong shock wave, often accompanied by instantaneous displacement, ejection, loud noise and air waves of the rock mass, which produces lateral and vertical impacts on the tunnel support equipment, which may cause damage and failure of the support. In severe cases, it may also cause the complete collapse of the tunnel and casualties of workers. Therefore, in order to ensure the safety of the hydraulic support, it is usually necessary to absorb the impact.

After the staff installs several energy absorbing rods 4 in turn, the staff inserts the energy absorbing plate 203 outside the energy absorbing plate 203. At this time, the staff presses the extrusion block 406, so that the locking block 405 The locking block 405 is lifted up and the locking shaft 404 is moved outward, so that the upper locking rod 402 is in close contact with the energy absorbing plate 203, and the energy absorbing rod 4 is in close contact with the energy absorbing plate 203.

Further, the adapter frame controller 201 can make the clamping reversing rod 905 move to the top of the replacement pin 804 through the cooperation of the vertical rod 8, the clamping motor 901, and the clamping reversing motor 904. At this time, the adapter frame controller 201 makes the clamping rod 907 close to the replacement pin 804 through the vertical rod 8. At this time, the adapter frame controller 201 controls the clamping rod 907 to work, thereby driving the feeding plate 909 to move, so that the The feeding plate 909 clamps the replacement pin 804.

At this time, the adapter frame controller 201 can monitor the position of the replacement pin 804 through the clamping camera 902 and the clamping camera 906. Due to the removal of the replacement pin 804, the pin moving rod 807 and the pin spring 808 cooperate to move the pin moving plate 805, thereby ensuring the stability of the replacement pin 804. Further, the adapter frame controller 20 1 controls the clamping rod 903 to extend, so that the replacement pin 804 is inserted into the through hole of the lower energy absorbing rod 403. When the replacement pin 804 moves to the end, the feeding plate 909 can be moved due to the action of the feeding rod 910 and the feeding spring 911, so as to ensure that the replacement pin 804 is flush with the outer surface of the lower energy absorbing rod 403, thereby ensuring the installation effect of the replacement pin 804. At this time, the adapter frame controller 201 controls the splash rod 410 to extend, so that the splash plate 411 rises, so that the splash head 412 is in close contact with the shaft pin 415. When the installation work of the entire device is completed, the controller 101 controls the right hydraulic rod 103, the The adapter buckle 104 and the left hydraulic rod 105 make the top beam 107 rise, so that the energy absorbing plate 203 is close to the coal mine tunnel, thereby ensuring the stability of the entire device. When the coal mine tunnel collapses, if the energy absorbing plate 203 is subjected to a large impact, the energy absorbing rod 4 drops so that the shaft pin 415 is cut off. At this time, the energy absorbing rod 4 drops. At this time, the energy absorbing spring 401 acts to absorb energy and buffer, thereby providing reaction time for the controller 101, thereby providing reaction time for the contraction of the right hydraulic rod 103 and the left hydraulic rod 105, thereby ensuring the service life of the entire device. At this time, the shaft pin 415 falls into the shaft pin storage box 206. At the same time, if the energy absorbing spring 401 breaks,Due to the function of the protective shaft 604, the energy absorbing spring 401 can be prevented from splashing. When the staff clears the fallen collapsed objects, the energy absorbing rod 4 rises due to the function of the energy absorbing spring 401. At this time, due to the function of the splash-proof shaft 414 and the splash-proof spring 413, the splash-proof head 412 moves, thereby transporting the broken end of the shaft pin 415 to the inside of the lower energy absorbing rod 403. The adapter frame controller 201 controls the entire device to reinstall the replacement pin shaft 804, thereby realizing automation, thereby increasing the service life of the entire device. After the replacement work is completed, the staff takes out the adapter frame 2. The adapter frame controller 201 controls the box door motor 205 to work, thereby driving the box door 204 to rotate, thereby opening the shaft pin storage box 206, thereby taking out the shaft pin 415 inside the shaft pin storage box 206, thereby facilitating the melting of the damaged shaft pin 415.
