A foot 41 is welded at the lower part of the leg 4, and the bottom of the foot 41 is provided with an anti-slip pattern. A chain 5 is hung between every two adjacent feet 41, and the chain 5 plays a role of limiting. A sleeve 6 is connected to the lower part of the arm 3, and the sleeve 6 is slidably connected to the leg 4. A trigger 7 is rotatably arranged on the sleeve 6, and the trigger 7 is inclined. A spring 8 is connected between the trigger 7 and the sleeve 6, and a limiting column 9 is connected to the lower part of the trigger 7, and the limiting column 9 clamps the adjacent leg 4. A first hook 10 is hung at the lower part of the connecting block 1, and the lower part of the first hook 10 is connected There is an assembly frame 11, and a small electric winch 12 is installed in the middle of the assembly frame 11. The electric winch 12 is an existing well-known technical product, which has a motor 13, a rope 14, a pulley 15, a second hook 101 and a remote control 16. The electric winch 12 is provided with a remote control 16, and the remote control 16 is electrically connected to the motor 13. A pulley 15 is provided at the lower part of the rope 14, and the lower part of the pulley 15 is connected to the second hook 101. A hoisting frame 18 is hung on the second hook 101, and a down-well vehicle 19 is connected to the hoisting frame 18. The down-well vehicle 19 moves downward to bring firefighters into the well for rescue. The down-well vehicle 19 is connected with a strap 202. A rotating bracket 201 is rotatably provided on the lower part of the well vehicle 19, and the rotating bracket 201 can fix personnel to enhance safety. A tool box 20 is slidably provided on the well vehicle 19. A square tilting rod 17 and an arc tilting rod 171 are also hung on the second hook 101. The square tilting rod 17 and the arc tilting rod 171 are used to open the manhole cover. A support frame 21 is hung on the lower part of the well vehicle 19. The front and rear parts of the support frame 21 are rotatably provided with a force-bearing wheel group 22. An upper folding plate 23 is connected to the support frame 21. A lower folding plate 23 is rotatably provided on the upper folding plate 23. After the folding plate 23 is removed and unfolded, it is convenient to transfer the wounded. A lifting rod 231 is welded on the lower folding plate 23.

[0031] When the device is needed, the firefighter first rotates the arm 3, the leg 4 and the foot 41 outward to unfold them, and the chain 5 plays a role of limiting. Then, the unfolded device is placed outside the manhole cover so that the chain 5 surrounds the manhole cover. Then, the assembly frame 11 and the electric winch 12 are hung on the connecting block 1 through the first hook 10. The firefighter can select the square tilting rod 17 or the arc tilting rod 171 on the second hook 101 according to the type of the manhole cover, and drive it to move downward and insert it into the air of the manhole cover through the electric winch 12. Then, the electric winch 12 is controlled to rotate in the opposite direction so that the second hook 101 drives the square tilting rod 17 or the arc tilting rod 171 to move upward, thereby opening the manhole cover.

[0032] After the manhole cover is opened, the electric winch 12 is controlled to drive the manhole vehicle 19 to move downward through the second hook 101, and the manhole vehicle 19 stops after moving to the side of the manhole. After the firefighter sits on the manhole vehicle 19, the rotating bracket 201 is used to fix the manhole vehicle 19, and the rescue tools are placed in the tool box 20. Then, the electric winch 12 is started again to make the manhole vehicle 19 continue to descend to the bottom of the manhole for rescue. After the person to be rescued is placed in the manhole vehicle 19 and fixed with the rotating bracket 201 and the strap 202, the electric winch 12 is controlled to drive the manhole vehicle 19 upward through the second hook 101 to rescue the person to be rescued. Finally, the firefighter can get out of the manhole through the manhole vehicle 19 or the fire safety sling.

[0033] After the rescue is completed, the support frame 21 is removed from the well vehicle 19, the folding plate 23 is unfolded to form a plane and placed on the ground, and the injured person is lifted onto the folding plate 23 to lie flat. The firefighters can then hold the lifting rod 231 tightly to push the injured person to the designated treatment position, thereby facilitating timely and rapid transfer and treatment of the injured person. The folding plate 23 together with the support frame 21 can also be used for rescue along with the well vehicle 19 when the rescued person is far away from the wellhead, so as to reduce the physical exertion of the firefighters and avoid unnecessary personal injuries. The rescued person referred to in this article is a person who is unconscious or seriously injured and unable to move.

[0034] When the device is not needed, all detachable objects are disassembled, and then the trigger 7 is pressed to drive the limit column 9 to rotate and no longer jam the leg 4, the spring 8 is compressed, and then the leg 4 is pushed upward to shorten, and then the trigger 7 is released, the spring 8 returns to its original state, driving the limit column 9 to rotate and reset, and finally the arm 3 and the leg 4 are rotated inward and folded, so as to facilitate carrying and transporting.
