The load-bearing plate 18 can be adjusted by adopting an adjustment assembly, thereby adjusting the supporting force of the load-bearing plate 18.
[0030] The support assembly includes a first support frame 12, which is arranged on the left and right sides of the base 1, and a first support plate 13 is movably connected to the upper surface of the first support frame 12, and a second support frame 14 is arranged on one side wall of the first support frame 12, and a second support plate 15 is movably connected to the upper surface of the second support frame 14, and a first connecting block 16 is fixedly connected to one side wall of the second support plate 15, and a first rotating shaft 17 is connected to the first rotating shaft 17 inside the first connecting block 16 for rotation, and the first rotating shaft 17 is connected to the first support plate 13 with each other, and a second fixing ring 24 is movably connected to one side wall of the first support frame 12 and the second support frame 14, and a connecting shaft 25 is connected to the inside of the first support frame 12 and the second support frame 14 for rotation. Since the first support frame 12 and the second support frame 14 can be used to adjust the first support plate 13 and the second support plate 15, the tail end of the coal mine can be fixed and reinforced.
[0031] The load-bearing component includes a first lifting rod 8, and the position of the first lifting rod 8 is set on the upper surface of the first sliding block 6.
