[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a coal mine filling mining surrounding rock support reinforcement frame includes a base plate 1, and the upper surface of the base plate 1 is connected to a hydraulic cylinder 2. The hydraulic cylinder 2 in this application is a common electrical device in the prior art. This application will not go into too much detail about its model or internal structure. It can also be replaced by other power sources. The bottom surface of the base plate 1 is connected to an embankment column 3. There are several embankment columns 3, which are evenly distributed on the bottom surface of the base plate 1. The embankment columns 3 are inserted into the rock layer or the ground. The device can be installed in a suitable position and is also convenient for disassembly.

[0024] One end of the hydraulic cylinder 2 is connected to a tooth plate 4, and the upper surface of the base plate 1 is connected to a fixed plate 14. A limiting groove 15 is provided on the upper surface of the fixed plate 14. The bottom surface of the tooth plate 4 is connected to a limiting plate 16. The outer surface of the limiting plate 16 is slidably connected to the inner wall of the limiting groove 15. The shape of the limiting groove 15 is consistent with the outer shape of the limiting plate 16. The limiting plate 16 can be just stuck in the limiting groove 15 to limit the movement of the tooth plate 4.

[0025] The outer surface of the tooth plate 4 is engaged with gear 1 5, and the outer surface of gear 1 5 is connected to a transmission rod 6, one end of the transmission rod 6 is connected to gear 2 7, and the transmission rod 6 is connected to the base plate 1 through a bracket. Gear 1 5 and gear 2 7 have the same shape and size and are gears of the same model. The outer surface of gear 2 7 is engaged with a gear column 8, and the outer surface of the gear column 8 is connected to a limit bar 17. The upper surface of the base plate 1 is connected to a semicircular arc 18, and the outer surface of the limit bar 17 is slidably connected to the outer surface of the semicircular arc 18. There are three limit bars 17, and the angle between the two limit bars 17 is 120 degrees. When the gear column 8 moves up and down, the limit bar 17 will slide on the outer surface of the semicircular arc 18. The presence of the limit bar 17 can prevent the gear column 8 from rotating.

[0026] The upper surface of the gear column 8 is connected to the workbench 9, and the outer surface of the workbench 9 is provided with a hollow fence, which improves the safety of the device. The hollow setting can reduce the weight of the workbench 9, making the device lighter. The upper surface of the base plate 1 is connected to the telescopic rod 19, and the top of the telescopic rod 19 is connected to the bottom surface of the workbench 9. The hydraulic cylinder 2 is the power source for the up and down movement of the workbench 9. The telescopic rod 19 is not the power source for the up and down movement of the workbench 9. When the workbench 9 moves up and down, the telescopic rod 19 is extended or shortened. When the workbench 9 is fixed at a certain height, the telescopic rod 19 is also at a certain height. Then the telescopic rod 19 is adjusted to a non-retractable state to prevent the workbench 9 from falling suddenly, thereby improving the safety of the device.

[0027] The bottom surface of the workbench 9 is connected to a motor 10. The motor 10 in this application is a common electrical device in the prior art. This application will no longer go into too much detail about its model or internal structure. It can also be replaced by other power sources. The output shaft end of the motor 10 is connected to a rotating rod 11. The output shaft end of the motor 10 drives the rotating rod 11 to rotate, providing power for the rotating rod 11. The rotating rod 11 rotates through the bottom surface of the workbench 9. The top of the rotating rod 11 is connected to a bent rod 12. An extension platform 13 is provided on one side of the bent rod 12. One end of the bent rod 12 is connected to a telescopic column 20. One end of the telescopic column 20 is connected to the outer surface of the extension platform 13. When the worker jumps onto the extension platform 13, the telescopic column 20 is extended or shortened. The length of the extension platform 13 can be adjusted for easy use. The bent rod 12 and the telescopic column 20 are made of ultra-high carbon steel, which can meet high strength requirements. The worker can be completely located above the extension platform 13.

[0028] The outer surface of the bent rod 12 is connected to an auxiliary rod 21, and the upper surface of the extension platform 13 is connected to a circular ring 22. The outer surface of the auxiliary rod 21 is slidably connected to the outer surface of the circular ring 22. The telescopic column 20 drives the extension platform 13 to rotate. At this time, the outer surface of the auxiliary rod 21 will slide on the outer surface of the circular ring 22. The auxiliary rod 21 can support the bent rod 12, thereby achieving the purpose of sharing the weight of the extension platform 13.

[0029] It should be noted that in actual use of the device, the embedded column 3 is inserted into the rock layer or the ground. When the height of the work platform 9 needs to be adjusted, the hydraulic cylinder 2 is started, and one end of the hydraulic cylinder 2 drives the tooth plate 4 to move. At this time, the outer surface of the limit plate 16 will slide on the inner wall of the limit groove 15 to limit the movement of the tooth plate 4. The movement of the tooth plate 4 drives the gear 1 5 to rotate, and the gear 1 5 drives the gear 2 7 to rotate through the transmission rod 6, and the gear 2 7 drives the tooth column 8 to move upward, thereby increasing the height of the work platform 9. At this time, the telescopic rod 19 also increases with the increase of the work platform 9. When the angle of the extension platform 13 needs to be rotated, the worker jumps onto the extension platform 13, and the motor 10 is started. The output shaft end of the motor 10 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the telescopic column 20 to rotate through the bent rod 12, and the telescopic column 20 drives the extension platform 13 to rotate. At this time, the outer surface of the auxiliary rod 21 will slide on the outer surface of the ring 22, so that the worker on the extension platform 13 can be moved to a certain angle, which is convenient for the worker to mine coal.
