At present, many high-rise buildings can use an attached lifting scaffold as auxiliary construction equipment for transferring workers to high places for construction operation, and in order to prevent the attached lifting scaffold from accidentally falling, safety accidents occur, so that the gravity centrifugal falling protector can be installed on a scaffold body.
The prior publication No. CN206279751U discloses a falling protector for an attached lifting scaffold, which comprises a falling protector comprising a falling protector swinging block and a linkage swinging block, wherein the falling protector swinging block and the linkage swinging block are fixedly connected to an attached wall support through a fixed shaft, and the falling protector swinging block and the linkage swinging block can rotate around the fixed shaft.
The working principle of the device is as follows: the rear part of the anti-falling swing block is provided with a return spring, the upper end of the return spring is hinged with the rear part of the anti-falling swing block, and the lower end of the return spring is hinged with a transverse partition plate on the wall-attached support. The reset spring has the advantages that when the guide rail of the scaffold normally descends, the linkage swing block is subjected to downward thrust of the positioning rod to rotate clockwise, so that the anti-falling swing block is driven to rotate clockwise, the reset spring is stretched to form downward tension on the tail of the anti-falling swing block, when the positioning rod continuously descends and leaves the linkage swing block, the thrust received by the linkage swing block disappears, the reset spring downwards pulls the tail of the anti-falling swing block to enable the anti-falling swing block to recover to the original position, the situation that after the pushing action of the current positioning rod disappears, the next positioning rod arrives before, the reset spring pulls the anti-falling swing block to recover to the head upwarping state under the normal working condition is achieved, and the scaffold can normally descend.
When the guide rail abnormally descends, the wall-attached guide rail is accelerated to fall, the convex strip structure of the linkage swing block is impacted by the outward inclining force of the positioning rod at the moment and far exceeds the pulling force of the reset spring, and the deflection angle of the linkage swing block relative to the anti-falling swing block is limited, so that the anti-falling swing block is triggered to deflect greatly in the clockwise direction, the head on the right side of the anti-falling swing block slides into the space between the two adjacent positioning rods, the left side of the anti-falling swing block is limited through the first limiting plate on the wall-attached support, and equivalently, a row of brake rods are inserted between the two adjacent positioning rods, and the purpose of stabilizing and.
The above prior art solutions have the following drawbacks: whether the device normally descends or abnormally descends, a return spring is required to be used, and repeated stretching of the return spring can lead to the elasticity of the return spring to be weakened, so that the return spring cannot normally function, and the normal use of the whole device is influenced.
