[0030] The supporting component 5 includes a hydraulic rod 13, the bottom of the hydraulic rod 13 is fixedly connected to the top of the base plate 1, the top of the hydraulic rod 13 is fixedly connected to a mounting plate 12, the end of the mounting plate 12 is fixedly connected to a protective frame 10, the protective frame 10 is an arc-shaped structure, the top of the protective frame 10 is provided with a groove 11, the end of the protective frame 10 is provided with a semicircular groove 16, the end of the base plate 1 is provided with a slide groove 15, the top of the base plate 1 is provided with a slide hole 14, the end of the protective frame 10 is provided with an extension component 6 connected to the semicircular groove 16, and the surface of the base plate 1 is provided with a stabilizing component 7.

[0031] In the present invention, there are two circular hole plates 2, and the two circular hole plates 2 are symmetrically arranged with the base plate 1 as the center. The circular hole plates 2 arranged at the bottom of the base plate 1 of the present invention limit the positioning ring 3, and the positioning ring 3 limits the roller 4. The base plate 1 is adjusted in position by the roller 4, which improves the convenience of the base plate 1 during adjustment and avoids the operator from carrying it. The bottom of the roller 4 extends to the bottom outer end of the circular hole plate 2. There are four rollers 4, and the four rollers 4 are arranged in two groups, and the number of each group is two; when the base plate 1 moves to the inside of the tunnel, the hydraulic rod 13 is started to move upward. When the hydraulic rod 13 moves upward, the protective frame 10 is pushed to contact the inner wall of the tunnel through the mounting plate 12, and the inner wall of the tunnel is squeezed by the protective frame 10 to avoid the rock inside the tunnel from falling off due to loosening.

[0032] In the present invention, there are two slide grooves 15 symmetrically arranged around the bottom plate 1 , the slide hole 14 is connected to the slide groove 15 , and there are two semicircular grooves 16 symmetrically arranged around the groove 11 .

[0033] In the present invention, the extension component 6 includes a force-bearing plate 22, the bottom of the force-bearing plate 22 is fixedly connected to a spring 25, the bottom of the spring 25 is fixedly connected to the bottom of the inner wall of the groove 11, the bottom of the force-bearing plate 22 is hinged to a triangular plate 23, the bottom of the triangular plate 23 is hinged to a moving rod 24, the end of the moving rod 24 is fixedly connected to a semicircular plate 20, and the end of the semicircular plate 20 away from the moving rod 24 is fixedly connected to an extension frame 21.

[0034] In the present invention, the surface of the semicircular plate 20 contacts the inner wall of the semicircular groove 16, that is, the semicircular plate 20 is inserted into the semicircular groove 16. When the protective frame 10 of the present invention moves upward, it pushes the force-bearing plate 22 to contact the inner wall of the tunnel. At this time, the force-bearing plate 22 will enter the interior of the groove 11 as the protective frame 10 moves. When moving, the force-bearing plate 22 will push the bottom of the triangular plate 23 to expand. When expanding, the triangular plate 23 pushes the moving rod 24 to move toward the inside of the semicircular groove 16. When moving, the moving rod 24 pushes the extension frame 21 toward the outer end of the protective frame 10 through the semicircular plate 20, thereby increasing the protection area of ​​the protective frame 10. The semicircular plate 20 is located at the end of the moving rod 24 away from the triangular plate 23, and the force-bearing plate 22 is located above the protective frame 10.

[0035] In the present invention, one end of the moving rod 24 away from the triangular plate 23 passes through the protection frame 10 and extends to the inside of the semicircular groove 16 , and one end of the extension frame 21 close to the semicircular plate 20 contacts the end of the protection frame 10 .

[0036] In the present invention, the stabilizing component 7 includes an elastic rod 30, the top of the elastic rod 30 is fixedly connected to the top of the inner wall of the protective frame 10, the bottom of the elastic rod 30 is fixedly connected to a connecting rod 33, the end of the connecting rod 33 is hinged to a tripod 31, the end of the tripod 31 is hinged to a right-angle plate 32, the right-angle plate 32 is slidably connected in the sliding hole 14, the end of the right-angle plate 32 away from the tripod 31 is fixedly connected to a slide plate 34, one end of the slide plate 34 extends out of the bottom plate 1 from the slide groove 15, the bottom of the slide plate 34 away from the right-angle plate 32 is fixedly connected to a telescopic plate 35, the bottom of the telescopic plate 35 is fixedly connected to the bottom of the tripod 31, and the bottom of the telescopic plate 35 is fixedly connected to the bottom of the tripod 31. The bottom of the slide plate 34 is fixedly connected with an inclined plate 36, the inclined surface section of which is inclined downward from the telescopic plate 35 toward the bottom plate 1, and the end of the inclined plate 36 corresponding to the bottom plate 1 is a pointed end. The bottom of the slide plate 34 is fixedly connected with an elastic rod 37, and the bottom of the elastic rod 37 is fixedly connected to the top of the inclined plate 36; when the hydraulic rod 13 is in a fully retracted state, the right-angle plate 32 abuts against the side wall of the sliding hole 14 near the edge of the bottom plate 1. At this time, the end of the slide plate 34 completely extends out of the bottom plate 1 through the sliding groove 15, and the inclined plate 36 is located on the outside of the circular hole plate 2, and the lower side of the inclined plate 36 abuts against the ground.

[0037] In the present invention, there are two tripods 31, and the two tripods 31 are symmetrically arranged with the connecting rod 33 as the center. When the protective frame 10 of the present invention moves upward, the elastic rod 30 pulls the connecting rod 33 to move. When the connecting rod 33 moves, the end of the tripod 31 is pulled to shrink. When the tripod 31 shrinks, the slide plate 34 is pulled to move toward the inside of the slide groove 15 through the right-angle plate 32. When the slide plate 34 moves, it pushes the inclined plate 36 to move at the bottom of the circular hole plate 2 through the telescopic plate 35. When the inclined plate 36 is aligned with the roller, the inclined plate 36 is pulled to move. When the surface of the wheel 4 contacts, the inclined plate 36 uses the pulling force of the upward movement of the hydraulic rod 13 to squeeze the surface of the roller 4. The inclined plate 36 squeezes the roller 4 to prevent the roller 4 from rolling when the protective frame 10 moves upward, thereby improving the stability of the protective frame 10 in protecting the tunnel. The surface of the right-angle plate 32 contacts the inner wall of the sliding hole 14 and extends to the inside of the slide groove 15. The surface of the slide plate 34 is slidably connected to the inner wall of the slide groove 15, and the top of the inclined plate 36 contacts the bottom of the circular hole plate 2.

[0038] When in use, the circular hole plate 2 arranged at the bottom of the bottom plate 1 limits the positioning ring 3, and the positioning ring 3 limits the roller 4. The bottom plate 1 is adjusted in position by the roller 4, which improves the convenience of the bottom plate 1 during adjustment and avoids the operator from carrying it. When the bottom plate 1 moves to the inside of the tunnel, the hydraulic rod 13 is started to move upward. When the hydraulic rod 13 moves upward, it pushes the protective frame 10 to contact the inner wall of the tunnel through the mounting plate 12. The protective frame 10 is used to squeeze the inner wall of the tunnel to prevent the rock inside the tunnel from falling off due to loosening. When the protective frame 10 moves upward, it pushes the force-bearing plate 22 to contact the inner wall of the tunnel. At this time, the force-bearing plate 22 will enter the inside of the groove 11 with the movement of the protective frame 10. When moving, the force-bearing plate 22 will push the bottom of the triangular plate 23 to expand. When the triangular plate 23 expands, it pushes the moving rod 24 to the semi-circular groove 11. The circular groove 16 moves inside, and the moving rod 24 pushes the extension frame 21 to move toward the outer end of the protective frame 10 through the semicircular plate 20 when moving, so as to increase the protection area of ​​the protective frame 10. When the protective frame 10 moves upward, the elastic rod 30 pulls the connecting rod 33 to move. When the connecting rod 33 moves, the end of the tripod 31 is pulled to shrink. When the tripod 31 shrinks, the slide plate 34 is pulled to move toward the inside of the slide groove 15 through the right-angle plate 32. When the slide plate 34 moves, it pushes the inclined plate 36 to move at the bottom of the circular hole plate 2 through the telescopic plate 35. When the inclined plate 36 contacts the surface of the roller 4, the inclined plate 36 uses the pulling force of the hydraulic rod 13 moving upward to squeeze the surface of the roller 4. The inclined plate 36 squeezes the roller 4 to avoid the rolling of the roller 4 when the protective frame 10 moves upward, thereby improving the stability of the protective frame 10 in protecting the lane.
