Expressway bridge engineering safety management anti-collision device

Abstract

The invention discloses an expressway bridge engineering safety management anti-collision device. The expressway bridge engineering safety management anti-collision device comprises two symmetrically-arranged vertical frames and a square frame fixed between the two vertical frames. A plurality of anti-collision plates are arranged in the square frame, one end of one anti-collision plate is rotationally connected to the lower portion of the square frame, the other end of the anti-collision plate is clamped in a clamping groove formed in the upper portion of the square frame, and a baffle is arranged at the position, close to the clamping groove, of the inner side face of the square frame. And the baffle is semicircular and is rotationally connected with the square frame through a rotating shaft. By arranging the multiple anti-collision plates, one end of one anti-collision plate is rotationally connected to the square frame, the other end of the anti-collision plate is subjected to rotation limitation of the anti-collision plate through the baffle, the anti-collision plate can be unfolded and folded by operating the baffle in the using process, and therefore the whole device does not need to be moved when passing is needed, and the problems in the prior art are solved.

Description

technical field [0001] The invention relates to the field of highway and bridge construction, in particular to an anti-collision device for highway and bridge engineering safety management. Background technique [0002] Highway and bridge engineering includes the bridge main body (namely the bridge superstructure and bridge substructure) engineering and the auxiliary engineering facilities in the overall bridge position. There are many affiliated engineering facilities, such as revetment, diversion embankment and other structures to regulate water flow in order to maintain the stability of the bridge at the river channel, approach bridges connecting the bridge head with the road, railings on the bridge surface to prevent wheel collisions, and sidewalks to ensure the safety of pedestrians Railings, as well as signs on the bridge, navigation signs under the bridge and bridge deck lighting equipment. [0003] Anti-collision devices are a kind of safety protection equipment in ...

AI Technical Summary

Problems solved by technology

[0003] The anti-collision device is a kind of safety protection equipment in the construction process of highway bridges. Most of the existing anti-collision devices are closed structures. When passing through, the anti-collision device needs to be removed as a whole, which is inconvenient to use.
