Construction safety anti-falling system

The invention belongs to the technical field of protective devices, and particularly relates to a construction safety anti-falling system which comprises a box body, and a guardrail is fixedly installed above the box body; the shaking-off mechanism is used for shaking off the disintegrating slag; the collecting mechanism is used for concentrating and collecting the disintegrating slag; and an amplification mechanism. According to the invention, disintegrating slag can be shaken off through the shake-off mechanism along with the movement of an operator, so that accidents such as stumbling, slipping and even falling from a high altitude when the operator moves on the suspension platform are reduced, and the collecting mechanism can be driven to rotate at a relatively large angle through the amplifying mechanism when the shake-off mechanism rotates at a relatively small angle, so that the collecting effect is improved. According to the anti-falling device, the disintegrating slag can be conveniently concentrated
