Description

Bridge construction safety prevents device that falls

Technical Field

The utility model relates to a safety protection technical field specifically is a device is prevented falling by bridge construction safety.

Background

In recent years, with the vigorous development of bridge construction, the anti-falling device used in bridge construction gradually appears in the use site of each bridge construction, in the bridge construction and use process, the bridge construction anti-falling device provides better safety guarantee in the use process, the existing anti-falling device is an anti-falling net generally, connecting ropes are arranged at four corners of the anti-falling net, the ropes are bound on the connecting pieces to play a role in preventing constructors from falling accidentally, although the structure of the anti-falling device is simple, the protection area of the anti-falling device is fixed, the anti-falling net needs to be cut into different areas for use in different construction places, the workload of erecting the anti-falling net is increased, the tightness degree of the whole anti-falling net is not easy to adjust, the over-looseness affects the protection area of the anti-falling net, and the over-tightness causes secondary falling injury to constructors.

The patent application No. CN201821067775.0 discloses a bridge construction safety anti-falling device, which comprises a locking hoop, one side of the locking hoop is fixedly connected with a pair of clamping plates, the outer walls of the clamping plates are provided with clamping grooves, the outer wall of the clamping groove is in threaded connection with a fastening screw, a rope is inserted into the inner cavity of the clamping groove and is fastened through the fastening screw, one end of the rope far away from the clamping groove is inserted into the inner cavity of the joint and is fastened through a fastening screw, one end of the joint far away from the rope is fixedly connected with a connecting rope, the end part of the connecting rope is connected with the fixed seat, the installation is convenient, the use number of the anti-falling net can be increased or reduced according to the actual requirement, the anti-falling net does not need to be cut, the working hours are saved, meanwhile, the tightening degree of the anti-falling nets can be adjusted by rotating the adjusting threaded rod, so that the whole anti-falling device is safer and more reliable.

However, in the actual use process, we find that the anti-falling net is only sleeved outside the rope through the flexible sleeve, although the tightness of the anti-falling net can be adjusted by adjusting the tightness of the rope, the flexible sleeve does not have the capability of limiting and fixing at the transverse position, so that when a person falls on the anti-falling net, the flexible sleeve is moved towards the middle to shrink due to the gravity of the person, and the anti-falling net falls and shrinks around the person supported above the anti-falling net, so that the effective contact supporting area is reduced, and the person above the anti-falling net falls off from the anti-falling net due to the uncontrollable swinging of the person and then continuously falls, which has a very high potential safety hazard.
