On the basis of any scheme, as shown in fig. 2, the falling protector 1 comprises a shell 2, and the first buffer is arranged inside the shell 2; the second buffer 3 is disposed outside the housing 2 and detachably connected to the housing 2. The arrangement enables a worker using the anti-falling device to start working at the first time once falling, and when the second buffer reaches the buffering limit, the first buffer starts working. This arrangement reduces the workload of the first damper in the fall arrester. And after the falling occurs, if only the second buffer is damaged, the second buffer can be replaced, and the service life of the product can be effectively prolonged.

As shown in fig. 4, this embodiment further provides a specific implementation manner of the first connector 4, where the first connector 4 is a safety rope connecting hook, and one end of the first buffer, which extends out of the housing 2 of the safety catcher, is connected to the safety rope connecting hook.

Wherein, the safety rope connecting hook can be a rotary safety hook with a self-locking function.

On the basis of any of the above solutions, as shown in fig. 6, this embodiment also provides a specific embodiment of the second buffer 3, and the second buffer 3 includes a safety belt 314 and a tear-away buffer webbing 311; one end of the safety belt 314 is detachably connected with the shell 2 of the falling protector, and the other end of the safety belt is detachably connected with the second connector 5; the tearing type buffer woven belt 311 is provided with a first tearing end 312 and a second tearing end 313, and the first tearing end 312 and the second tearing end 313 are respectively fixedly connected with two ends of a safety belt. When falling from high altitude, the two ends of the tearing type buffer mesh belt are torn simultaneously to absorb impact energy together, so that the buffer effect is good; the safety belt is used for preventing people from continuously falling when the tearing type buffering woven belt is completely torn. The tearing type buffer woven belt can be formed by tightly attaching two woven belts together in sewing, bonding and other modes, and has a certain working starting force value when being torn.

The two ends of the safety belt 314 are respectively provided with a first annular hanging part 315 and a second annular hanging part 316; the shell 2 of the falling protector is provided with a connecting seat 6 which is detachably connected with a first hanging part 315, and the first hanging part 315 is detachably connected to the connecting seat 6; the second hanging portion 316 is detachably connected to the second connector 5. The first tearing end 312 is fixedly connected with the first hanging part 315, and the second tearing end 313 is fixedly connected with the second hanging part 316.

As shown in fig. 3, the connection seat 6 may be configured to include two lugs 611, the first hanging portion 315 is detachably connected between the two lugs 611 through a bolt 612 and a nut 613, and the first hanging portion 315 is sleeved on the bolt 612.

when the anti-falling device is used, the second buffer 3 is arranged at the upper end of the shell 2 of the anti-falling device, the first buffer is arranged in the shell, and the second buffer 3 and the first buffer form a series connection relation. When falling from high altitude, the second buffer starts to work at first, and when the buffering effect of the second buffer reaches the limit, the first buffer can also continue to exert the buffering effect, so that the falling impact force of the personnel falling from high altitude can be effectively reduced, and the falling protector of the single buffer is prevented from causing the falling personnel to be injured by impact when reaching the buffering limit.

Because the working starting power value of the first buffer is larger than that of the second buffer 3, when the quality is detected, the second buffer 3 firstly reaches the limit value of the second buffer to damage or lose the buffering effect, and the limit value is smaller than the working starting power value of the first buffer, so that the damage to the first buffer is small, the quality of the first buffer can be ensured after the detection, and the first buffer can be continuously used. And the second buffer 3 can be disassembled to be replaced by a new second buffer 3 after being detected, so that the anti-falling device can be continuously used, and the service life of the product is effectively prolonged.

The utility model is not limited to the above optional embodiments, and all the schemes can be combined arbitrarily on the premise of no conflict; any person can get other various products according to the teaching of the present invention, and any change in the shape or structure will fall within the scope of the present invention.
