[0030] Specifically, when using the support equipment, first fix the main body of the support device, fix the pillar 1 to the ground through the fixing assembly, fix the support frame 2 to the top of the pillar 1, and then fix the square frame 3 to the outside of the top of the support frame 2 through bolts 10, and fix the arc plate 5 and the arc frame 6 to the top of the square frame 3. A plurality of fixing blocks 11 are arranged on the top of the support frame 2 to be inserted into the square frame 3, and a plurality of card boxes 8 are arranged on the inside of the square frame 3. A latch 13 is slidably arranged inside the card box 8. Pull the handle 12 outward to compress the tension spring 14 using the fixing plate 15. After the fixing block 11 is inserted into the square frame 3, release the handle 12, and the latch 13 is inserted into the inside of the square frame 3 and the fixing block 11 using the pre-opened holes to fix the support frame 2 and the square frame 3.

[0031] Reference Figure 1 and Figure 3 The fixing component includes a shell 9, the outer side of the shell 9 is fixedly connected to the inside of the bottom plate 4, the inside of the shell 9 is rotatably connected to a screw rod 16, the outer side of the screw rod 16 is threadedly connected to a slider 18, the four corners of the outer side of the slider 18 are fixedly connected to a limit plate 22, the outer side of the slider 18 is fixedly connected to a base 17, the internal rotating ring of the base 17 is connected to a ground nail 20, a plurality of slots 19 are provided on the outer side of the shell 9, the outer side of the slider 18 is fixedly connected to a spring 21, one end of the spring 21 away from the slider 18 is fixedly connected to the outer side of the ground nail 20, and the outer side of the limit plate 22 is slidably connected to the inner wall of the shell 9.

[0032] Specifically, after roughly fixing the pillar 1, the shell 9 inside the base plate 4 is inserted into the ground, and then the screw 16 inside the shell 9 is rotated, and the slider 18 slides downward inside the shell 9 through the limit plate 22. There are bases 17 around the slider 18, and a ground nail 20 is also rotated on the inner side of the base 17, and a slot 19 is opened at a suitable position of the shell 9. In the process of the slider 18 sliding downward, under the elastic force of the inner spring 21, the ground nail 20 will slide out of the shell 9 and penetrate into the ground when passing through the slot 19, thereby completing the fixation. When it needs to be removed, just rotate the screw 16 in the opposite direction.

[0033] Working principle: When supporting the mine, first fix a plurality of pillars on the ground, then install the support frame 2 on the top of the pillar 1, connect the square frame 3 with bolts 10 on the four sides of the top of the support frame 2, and then set a plurality of arc frames 6 on the left and right sides of the top of the square frame 3.

In addition to the bolts 10 used to fix the support frame 2 and the square frame 3, a fixing block 11 is set on the top of the support frame 2. The fixing block 11 is inserted into the square frame 3. A plurality of card boxes 8 are set on the inside of the square frame 3. Pull the handle 12 inside the card box 8, and the fixing plate 15 compresses the tension spring 14 inward, and the tension spring 14 is loosened at this time. When the handle 12 is opened, the latch 13 is pushed into the square frame 3 and the fixed block 11 by the tension spring 14. After the structure above the supporting equipment is installed, the pillar 1 is fixed. A base plate 4 is installed at the bottom of the multiple pillars 1, and a shell 9 is fixed inside each base plate 4. A screw 16 and a slider 18 are arranged inside the shell 9. By manually turning the screw 16, the slider 18 slides downward, because the outer side of the slider 18 is surrounded by a base 17 and a ground nail 20, and the shell 9 is surrounded by slots 19. When the slider 18 slides downward, the ground nails 20 around the slider 18 are subjected to the outward elastic force of the spring 21. When the ground nails 20 pass through the slots 19, the ground nails 20 will be inserted into the soil around to firmly fix the pillar 1.
