When a heavier object or a constructor falls on the anti-falling safety net 103, the anti-falling safety net 103 is close to the middle by impact, so that ropes at two ends of the anti-falling safety net 103 pull the first fixing blocks 207 to move outwards, the first fixing blocks 207 move outwards to drive the T-shaped sliding rods 205 to move outwards, the T-shaped sliding rods 205 move outwards to squeeze the first springs 206, the T-shaped sliding rods 205 move outwards along with the outward movement of the T-shaped sliding rods 205, the n-shaped pushing rods 3 move outwards, the n-shaped pushing rods 3 drive the pistons 4 to move outwards, the pistons 4 push hydraulic oil in the first shell 301 to move, and through hole baffles 302 are arranged in the first shell 301 and block the flow of the hydraulic oil, so that the ropes at two ends of the anti-falling safety net 103 are blocked in the moving process, namely, the people or objects falling on the anti-falling safety net 103 are subjected to preliminary buffer protection.

When the piston 4 moves outwards to push the hydraulic oil in the first housing 301, under the action of the hydraulic oil in the first housing 301, the convex sliding block 405 moves inwards, the second spring 406 is compressed by the inward movement of the convex sliding block 405, meanwhile, the cylindrical hole 403 is communicated with the interior of the first housing 301 by the inward movement of the convex sliding block 405, the hydraulic oil in the first housing 301 enters the annular groove 401 through the concave limiting groove 402 and the cylindrical hole 403, the extrusion of the sealing ring 404 is completed, and the contact between the piston 4 and the first housing 301 is sealed.

With the friction between the sliding shell 315 and the friction plate of the T-shaped sliding rod 205, the sliding shell 315 will continue to move inwards to press the n-shaped sensing block 502 to move inwards, the n-shaped sensing block 502 moves inwards to drive the third limiting plate 501 to move inwards, the third limiting plate 501 moves inwards to press the two ratchet bars 504 to move towards each other, the two ratchet bars 504 move towards each other to press the third spring 505, when the third limiting plate 501 moves inwards to release the pressing of the two ratchet bars 504, the two ratchet bars 504 are relatively ejected under the action of the third spring 505, so that the ratchet bars 504 are always in contact with the wedge blocks of the third limiting plate 501, and when the ratchet bars 504 are in contact with the wedge blocks of the third limiting plate 501, the third limiting plate 501 cannot move outwards.

When constructor gets down from the anti-falling safety net 103, under the action of the first spring 206, the T-shaped slide bar 205 moves inwards, the T-shaped slide bar 205 drives the two pistons 4 to move inwards through the n-shaped push rod 3, when the pistons 4 move inwards, the convex slide block 405 moves outwards in the concave limit groove 402 under the action of the second spring 406 to restore to the original state, at this time, the convex slide block 405 shields the cylindrical hole 403, hydraulic oil in the cylindrical hole 403 continuously applies pressure to the sealing ring 404 to enable the adjacent pistons 4 and the first shell 301 to keep sealing, so that as the pistons 4 move inwards, the pistons 4 extract the hydraulic oil in the first shell 301, the hydraulic oil in the second shell 306 enters the first shell 301 through the first conveying pipe 303, the hydraulic oil flows out of the second shell 306, the first slide block 309 moves inwards, and the subsequent movement is opposite to the above movement, finally, the two sliding shells 315 are separated from each other by the relative movement, when the two sliding shells 315 move relatively, the second fixed plate 5 is in contact with the third limiting plate 501, the sliding shells 315 are limited, the distance between the sliding shells 315 and the friction plates of the T-shaped sliding rods 205 is always consistent, because the friction plates on the T-shaped sliding rods 205 are worn, the T-shaped sliding rods 205 are not restored to the initial state, the T-shaped sliding rods 205 continue to move inwards under the action of the first springs 206, the T-shaped sliding rods 205 drive the pistons 4 to move inwards through the n-shaped push rods 3, the pistons 4 always have extraction acting force on the liquid in the first shell 301, the sliding shells 315 are limited and can not move, then the check valves on the second conveying pipes 511 are opened, the hydraulic oil in the storage cylinders 509 enters the first shell 301 through the second conveying pipes 511, the two second sliding blocks 510 move towards each other along with the reduction of the hydraulic oil in the storage cylinders 509, finally, the T-shaped slide bar 205 is restored to the initial state, and the hydraulic oil in the first shell 301 is set, so that the device is not quickly reset under the action of the first spring 206 after buffering is completed, and the constructor on which the anti-falling safety net 103 is sprung is avoided.

After the construction is finished, after the device is disassembled to the ground, a constructor opens the first protective shell 2 to check the friction plate on the T-shaped sliding rod 205, if the friction plate needs to be replaced, the friction plate is directly replaced, then the constructor presses the long plate 506 downwards to tighten the ratchet bars 504 in opposite directions, the limitation on the third limiting plate 501 is removed, then the second conveying pipe 511 below the first shell 301 is pulled out, the constructor manually pulls the two sliding shells 315 to restore the initial state, then the long plate 506 is loosened, then the second conveying pipe 511 is communicated with the first shell 301 again, and then the storage cylinder 509 is filled with hydraulic oil.
