[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-6 The utility model provides a technical solution: a mine slope protection and anti-slip device, comprising two slope protection frame plates 1 and limit blocks 2 located on the two slope protection frame plates 1. Limit grooves 3 that are compatible with the limit blocks 2 are opened on the four sides of the top of the slope protection frame plate 1, and reinforcement grooves 4 are opened on both sides of the inner cavity of the limit groove 3. Both sides of the front and rear parts of the limit block 2 are fixedly connected with reinforcement plates 5 that are compatible with the reinforcement groove 4. The top of the slope protection frame plate 1 is provided with mounting grooves 10 that communicate with the limit groove 3. One side of the inner cavity of the mounting groove 10 is fixedly connected to the limit cylinder 6. The inner sliding connection of the limit cylinder 6 is connected to the limit rod 7. One end of the limit rod 7 is fixedly connected to the limit plate 8. A spring 9 is sleeved between the surface of the limit cylinder 6 and the surface of the limit rod 7. A card slot 11 that is compatible with the limit plate 8 is opened on both sides of the limit block 2.

[0023] Furthermore, in order to protect the slope protection, support blocks 12 are fixedly connected to the bottom of the inner cavity of the slope protection frame 1 on all sides, and an installation frame 13 is slidably connected to the inside of the slope protection frame 1 and above the support blocks 12, and a protective net 14 is fixedly installed inside the installation frame 13.

[0024] Furthermore, in order to facilitate the replacement of the protective net 14 , the top of the support block 12 is threadedly connected to a threaded rod 15 through an opening, and threaded holes 16 matching the threaded rod 15 are provided around the top of the installation frame 13 .

[0025] Furthermore, in order to fix the slope protection frame 1 on the ground, a sliding hole 18 is opened on the top of the limiting block 2, and the interior of the sliding hole 18 is slidably connected to the limiting nail 17.

[0026] Furthermore, in order to facilitate pulling the limiting plate 8 , a pulling plate 19 is fixedly connected to the top of the limiting plate 8 .

[0028] When the limit block 2 is inserted downward into the two limit grooves 3, the limit block 2 will squeeze the inclined surfaces of the limit plates 8 in the two installation grooves 10 downward, so that the limit plate 8 is squeezed and retracted into the installation groove 10 through the limit cylinder 6 and the limit rod 7. When the limit plate 8 encounters the slot 11, the limit rod 7 is pushed by the force of the spring 9 to drive the limit plate 8 to move, and the limit plate 8 is inserted into the slot 11 on the limit block 2, so that the limit plate 8 limits the limit block 2, and the two slope protection frame plates 1 are spliced and fixed together through the limit block 2, and then the limit nails 17 are inserted into the sliding holes 18 underground of the slope protection, so that the limit nails 17 fix the two slope protection frame plates 1 on the slope protection through the sliding holes 18, and the slope protection is covered with the protective net 14 in the slope protection frame plate 1 to prevent the slope protection from landslide;

[0029] When the protective net 14 is damaged, the plurality of threaded rods 15 are rotated out of the threaded holes 16 , thereby disassembling the mounting frame 13 and the protective net 14 for replacement.
