Deck type bridge pier high-altitude construction anti-falling device capable of automatically ascending and descending

Abstract

The invention relates to the technical field of bridge pier safety devices, and provides a deck type automatic lifting bridge pier high-altitude construction anti-falling device which comprises an anti-falling mechanism, a driving mechanism and a locking mechanism and is characterized in that the anti-falling mechanism comprises a supporting ring arranged on a bridge pier in a sleeving mode and an anti-falling net arranged on the supporting ring; the driving mechanism comprises a plurality of driving wheels rotationally arranged on the supporting ring, and the driving wheels are attached to the side wall of the bridge pier; the locking mechanism comprises a brake rod and a first spring, the brake rod is hinged to the supporting ring, the end of the brake rod abuts against or breaks away from the pier, the free end of the brake rod inclines downwards, the two ends of the first spring are arranged on the brake rod and the supporting ring respectively, and the first spring provides force for the brake rod to get close to the pier. By means of the technical scheme, the problem that time and labor are wasted when an anti-falling net is installed on a pier in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of bridge pier safety devices, in particular to an upper-supporting type anti-falling device for high-altitude construction of bridge piers that can be lifted automatically. Background technique [0002] Any operation at a height above 2m (including 2m) of the datum plane of the drop height, which may fall, is called high-altitude operation. There are great safety hazards in high-altitude operations, and generally a variety of safety measures must be taken, such as safety helmets, safety ropes, safety fences, safety ladders, and anti-fall devices. Among them, the anti-fall device is the last line of defense for high-altitude safety measures. [0003] In the construction of bridge piers and columns, because the height of the working surface of the piers continues to rise, and the surface of the piers is generally free of attachments, the anti-falling net cannot be installed, and it is more difficult to chang...
