An anti-drop device for bridge construction

Abstract

The invention discloses a bridge construction anti-falling device. The bridge construction anti-falling device structurally includes an acting force compensation rope positioning device, a fixing bolt, a connecting fixing block, an anti-falling device rack, an installation embedded groove, a sealing installation plate, a central rotating shaft, a rope output column and a moving rope, the acting force compensation rope positioning device is arranged and connected to the upper end of the connecting fixing block by welding, the fixing bolt is arranged and connected to the front end face of the connecting fixing block by thread installation, and the connecting fixing block is arranged and connected to the upper end of the anti-falling device rack by fixed installation. According to the bridgeconstruction anti-falling device, a structure automatically compensating for the balance of the acting force applied to the rope in the process of bridge construction by construction personnel is provided, the rope is prevented from overloading, and the service life of the rope is affected; and meanwhile, a structure automatically maintaining the anti-falling device is provided, maintenance forgetting due to the negligence is effectively avoided, and thus impact on working of the anti-falling device is caused.

Description

technical field [0001] The invention relates to the technical field of bridge construction, more precisely, it relates to a bridge construction anti-falling device. Background technique [0002] In the process of bridge construction, due to the high construction position, the construction personnel need to use the anti-fall device to prevent falling during the construction process, and the anti-fall device has higher safety. But there is following shortcoming in this anti-drop device at present: [0003] 1. During the construction of the bridge, the construction personnel do not stay in the same position and remain still, but need to move frequently. During the movement, the rope at the upper end of the anti-fall device will be subjected to an inclined force, and the surrounding area of ​​the rope will be tilted. The unbalanced force will easily cause the rope to be temporarily overloaded, and as time changes, it will affect the service life of the rope. [0004] 2. At the...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a bridge construction anti-falling device to solve the problem in the prior art that during the construction of the bridge, the construction personnel do not stay in the same position to keep still, but need to Frequent movement. During the movement, the rope at the upper end of the anti-fall device will be subjected to an inclined force, and the force on the surroundings of the rope will be out of balance, which will easily cause a short-term overload of the rope. Over time, it will affect the rope. At the same time, the maintenance of the anti-drop device is manually maintained. When the maintenance is forgotten due to negligence, it is easy to cause the friction force to increase when the internal ratchet of the anti-drop device moves, which will affect the work of the anti-drop device.
