The upper end of the screw rod 25 is threaded into the bottom of the movable support block 23, and an adjusting head 26 is fixedly provided at the lower end of the screw rod 25. By rotating the screw rod 25, the position height of the movable support block 23 can be adjusted, so that the position height of the six movable support blocks 23 can be adjusted according to the top shape of the old cave to be supported, so that the top of the fixed support block 22 and the six movable support blocks 23 can effectively contact the top of the old cave, so as to better achieve effective support and reinforcement of the old cave, and then better ensure the safety of the cleaning personnel inside the old cave. The seat body 1 is internally movably provided with a U-shaped seat 5, and a U-shaped seat 5 is fixed on the seat body 1 below the U-shaped seat 5. A hydraulic cylinder 6 is installed, a battery pack 7 is fixedly connected to the seat body 1 on the front side of the hydraulic cylinder 6, a control switch 8 is fixedly installed on the front side of the battery pack 7, the hydraulic cylinder 6, the battery pack 7 and the control switch 8 are connected in series through a wire, the telescopic end of the hydraulic cylinder 6 is fixedly connected to the U-shaped seat 5, through grooves 51 are symmetrically provided on both sides of the U-shaped seat 5, and a connecting groove 52 is provided on the side wall of the through groove 51, side support plates 4 are symmetrically provided on both sides of the seat body 1, a connecting seat 41 is provided on the side of the side support plate 4 close to the seat body 1, the connecting seat 41 slides along the rectangular groove and the through groove 51 provided on the side wall of the seat body 1, and connecting slide columns 411 are symmetrically provided on the front and rear sides of the connecting seat 41, the connecting slide columns 411 slide along the connecting slide groove 52, and an anti-slip tooth 42 is provided on the side of the side support plate 4 away from the seat body 1 The hydraulic cylinder 6 pushes the U-shaped seat 5 to move upward, and the connecting slide column 411 and the connecting slide groove 52 cooperate to drive the connecting seat 41 and the side support plate 4 to move outward, so that the side support plate 4 contacts the side wall of the old cave and supports the side wall of the old cave. The setting of the anti-slip teeth 42 can also prevent the side support plate 4 from moving forward and backward, thereby making the seat body 1 more stable. When the old cave is safely supported and reinforced, the device can be moved to the position to be supported, and then the hydraulic cylinder 6 pushes the U-shaped seat 5 to move upward. At this time, the cooperation of the connecting slide column 411 and the connecting slide groove 52 can drive the two side support plates 4 to move toward the two sides of the old cave respectively and effectively contact the two sides of the old cave. Then, the adjusting disk 31 is manually turned clockwise to drive the screw rod 3 to rotate.The rotation of the screw rod 3 can drive the safety support seat 2 to move upward, so that the top of the fixed support block 22 can effectively abut against the top of the old cave. Then the six adjustment heads 26 can be rotated one by one to drive the screw rod 25 to rotate, and the position height of the six movable support blocks 23 can be adjusted, so that the tops of the six movable support blocks 23 can effectively abut against the top of the old cave, and the safety support reinforcement of the old cave can be completed.

[0022] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the bottom of the seat body 1 is symmetrically provided with a storage groove 11, and a wheel frame 9 is movably provided inside the storage groove 11. A moving wheel 91 is rotatably connected to the wheel frame 9 through a wheel axle. Limiting sliders are provided on both sides of the wheel frame 9, and the limiting sliders slide along the limiting slide grooves provided on the side walls of the storage groove 11 to limit the wheel frame 9. The top of the wheel frame 9 extends to the slide groove where the U-shaped seat 5 is located, and the U-shaped seat 5 slides along the slide groove. When the U-shaped seat 5 moves upward, the wheel frame 9 loses the squeezing of the U-shaped seat 5 and can be automatically stored in the storage groove 11, so that the bottom of the seat body 1 contacts the ground of the old cave, so that the seat body 1 can be parked stably. When the U-shaped seat 5 moves downward, it can squeeze the wheel frame 9 downward, so that the lower part of the wheel frame 9 moves out of the storage groove 11, and the moving wheel 91 contacts the ground. At the same time, the seat body 1 can be separated from the ground, so that it is convenient for personnel to move the device, which is more convenient and labor-saving.

[0023] Working principle: When in use, when the old cave is being safely reinforced, the device can be moved to the position to be supported, and then the U-shaped seat 5 is pushed upward by the hydraulic cylinder 6. At this time, through the cooperation of the connecting slide column 411 and the connecting slide groove 52, the two side support plates 4 can be driven to move toward the two sides of the old cave respectively, and effectively contact with the two sides of the old cave. Then, the adjusting disk 31 is manually rotated clockwise to drive the screw rod 3 to rotate. The rotation of the screw rod 3 can drive the safety support seat 2 to move upward, so that the top of the fixed support block 22 is effectively abutted against the top of the old cave. Then, the six adjusting heads 26 can be rotated one by one to drive the screw rod 25 to rotate, and the six movable support blocks 23 The position height can be adjusted so that the tops of the six movable support blocks 23 are effectively in contact with the top of the old cave, thereby completing the safety support and reinforcement of the old cave. When the U-shaped seat 5 moves upward, the wheel frame 9 can be automatically stored in the storage groove 11 after losing the squeezing of the U-shaped seat 5, so that the bottom of the seat body 1 is in contact with the ground of the old cave, so that the seat body 1 can be parked stably. When the U-shaped seat 5 moves downward, it can squeeze the wheel frame 9 downward, so that the lower part of the wheel frame 9 is moved out of the storage groove 11, and the moving wheel 91 is in contact with the ground. At the same time, the seat body 1 can be separated from the ground, so that it is convenient for personnel to move the device, which is more convenient.
