Movable road and bridge construction safety protection device

Abstract

The invention belongs to the technical field of road and bridge construction, and particularly relates to a movable road and bridge construction safety protection device which comprises a landing frame. The lifting mechanism is fixedly connected to the top of the landing frame, and the lifting mechanism is used for lifting a top structure; the connecting assembly is fixedly connected to the outer sides of the lifting mechanisms, and the connecting assembly is used for fixing the position between the two lifting mechanisms; the vertical rod is movably connected to the inner wall of the lifting mechanism, the arranged connecting assembly facilitates combination of the two landing frames, the weight of the structure on the bridge floor is increased, the toppling condition is avoided, after the arranged storage assembly is opened, construction tools and the like can be conveniently placed, and operation is convenient; during working, a constructor can stand on the treading bottom plate and construct or maintain the side edge of a constructed road and bridge.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a mobile road and bridge construction safety protection device. Background technique [0002] Although water conservancy projects improve traffic conditions, they cannot replace land traffic. Therefore, roads and bridges have become the basic conditions for land traffic. Bridge construction is the process of building bridges according to the design content; mainly refers to bridge construction technology and construction organization. , construction management, construction quality, etc., among which, engineering construction refers to the construction of bridgehead approach roads and diversion buildings. The river beach embankment part of the bridgehead approach road should be filled with highly permeable soil, and masonry should be used to protect the slope to prevent erosion. , The diversion buildings are mostly in the dry season, and they are built on sit...

AI Technical Summary

Problems solved by technology

[0003] Safety protection devices can be used during bridge maintenance or construction. The existing maintenance and construction of the side of the bridge and the bottom of the side generally use vehicles to lift people to the working position through ladders, but bridges on rivers and When the bridge body is too high, it is difficult to operate, and the construction vehicles occupy a large area, and parking on the bridge surface will also affect the traffic, and it is inconvenient to use
