[0039] The present application also provides a method for buffering falling objects from high altitude, comprising the following steps:

[0040] Setting up the above-mentioned building safety passage with buffer function;

[0041] When objects falling from a high altitude fall onto the channel top cover 100, they impact the flip plate 130. When the flip plate 130 is impacted by the objects falling from a high altitude, it rotates to open the object drop opening 120 and twists the torsion spring 150. After the objects fall onto the foam block 180 through the object drop opening 120, the twisted torsion spring 150 pushes the flip plate 130 to rotate in the opposite direction to close the object drop opening 120, thereby completing the buffering and receiving of objects falling from a high altitude.

[0042] The control electric push rod 390 is used to drive the switch plate 340 to rise and open the discharge port 190 at one end of the channel top cover 100, and the control pushing component 300 drives the upper push plate 310 to move along the length direction of the channel top cover 100 to push the fallen objects on the foam block 180 out of the buffer chamber 110 through the discharge port 190. Then the control pushing component 300 drives the upper push plate 310 to move in the opposite direction along the length direction of the channel top cover 100 to reset, and the control electric push rod 390 drives the switch plate 340 to descend and close the discharge port 190, thereby completing the fallen object removal operation.

[0043] The end plate 103 is provided with a discharge port 190 connected to the buffer chamber 110 and a accommodating chamber 290 connected to the discharge port 190 at the bottom. A switch plate 340 that can be raised and lowered to open and close the discharge port 190 and an electric push rod 390 for driving the switch plate 340 to rise and fall are provided in the accommodating chamber 290. An upper push plate 310 and a pushing assembly 300 for driving the upper push plate 310 to move along the length direction of the channel top cover 100 are also provided in the buffer chamber 110. When the upper push plate 310 moves along the length direction of the channel top cover 100, it pushes the object on the impact-resistant steel plate 160 out of the buffer chamber 110 through the discharge port 190. The pushing assembly 300 includes a screw rod 320, one end of which is rotatably connected to the end plate 103 provided with the discharge port 190 after passing through the upper push plate 310 through a thread. A pushing motor 330 with an output shaft connected to the other end of the screw rod 320 is provided in the other end plate 103.

[0044] The embodiment of the present application provides a building safety passage with a buffering function and a method for buffering falling objects from a high altitude. Two rows of legs 400 are provided to support the passage top cover 100, a buffer chamber 110 and an impact-resistant steel plate 160 that can be lifted and lowered are provided in the passage top cover 100, and a drop port 120 and a flip plate 130 that can flip to open and close the drop port 120 are provided on the top of the passage top cover 100. When falling objects from a high altitude fall onto the flip plate 130, the impact force pushes the flip plate 130 to rotate around the corresponding rotating shaft 140 to open the drop port 120 and twist the torsion spring 150, so that the falling objects from a high altitude fall through the drop port 120 to the impact-resistant steel plate 160 for buffering and accommodation, and the twisted torsion spring 150 pushes the flip plate 130 to rotate and close the drop port 120, thereby preventing falling objects from hitting the passage top cover 100 and bouncing off and injuring workers, and also preventing collision damage to the passage top cover 100, and effectively buffering and accommodating falling objects from a high altitude.

[0045] By sequentially arranging a buffer pad 170 and a foam block 180 on the top of the impact-resistant steel plate 160, the impact force of falling objects from a high altitude can be effectively buffered. At the same time, by arranging a buffer assembly 200 connected to the bottom of the impact-resistant steel plate 160, the buffering capacity can be further improved. When the impact-resistant steel plate 160 is subjected to the impact force, it moves downward to push the bottom hinged rotating rod 240 to rotate. When the rotating rod 240 rotates, it pushes the hinged rolling seat 210 to move along the corresponding rolling groove 250, and when the rolling seat 210 moves, it pushes the connected moving rod 220 to move axially. When the moving rod 220 moves axially, it compresses the upper sleeve The two ends thereof press against the buffer springs 230 corresponding to the rolling seat 210 and the inner wall of the side plate 102, and after the impact force disappears, the compressed buffer spring 230 pushes the moving rod 220 and the rolling seat 210 to move in the opposite direction and reset, so that the rolling seat 210 pushes the rotating rod 240 to rotate in the opposite direction and pushes the impact-resistant steel plate 160 to rise and reset, thereby effectively accommodating sharp or irregular objects dropped from a high place during the construction process, and buffering the huge impact force caused by the free fall of steel pipes, fasteners or other irregular objects dropped during the dismantling stage of the outer frame, avoiding the safety hazard of the channel top cover 100 being cracked or bounced to other locations.

[0046] By arranging an upper push plate 310 that moves along the length direction of the channel top cover 100 and a pushing assembly 300 for driving the upper push plate 310 in the buffer chamber 110, and providing a discharge port 190 that is connected to the buffer chamber 110 and a switch plate 340 that can be lifted and opened to open and close the discharge port 190 on the end plate 103, it is convenient for a user to control the electric push rod 390 to drive the switch plate 340 to lift and open the discharge port 190, and control the pushing motor 330 of the pushing assembly 300 to rotate to drive the screw rod 320 to rotate, so that the upper push plate 310 that is threadedly sleeved on the screw rod 320 can be easily moved. 10 moves along the screw rod 320 to push the high-altitude fallen objects on the foam block 180 to be discharged through the discharge port 190, and then controls the pushing motor 330 to rotate in the opposite direction to drive the screw rod 320 to rotate in the opposite direction, so that the upper push plate 310 threadedly mounted on the screw rod 320 moves in the opposite direction and resets, and controls the electric push rod 390 to drive the switch plate 340 to descend and close the discharge port 190, thereby completing the discharge and cleaning operation of the high-altitude fallen objects, solving the problem of too many fallen objects accumulating in the buffer chamber 110 of the channel top cover 100, and avoiding the problem of unsafe manual cleaning of the buffer chamber 110.

[0047] A socket 105 corresponding to the leg 400 is provided at the bottom of the base plate 101 of the channel top cover 100, and a slot 106 for snapping into the top of the leg 400 is provided at the bottom of the socket 105. The socket 105 and the leg 400 are detachably connected by a bidirectional threaded rod 107 passing through the two and a fastening nut 108 respectively sleeved on both ends of the bidirectional threaded rod 107, which can facilitate users to assemble and disassemble the base plate 101 and the leg 400, thereby improving the loading and unloading convenience of the building safety passage with buffer function, and facilitating movement, transportation and use.
