A bridge alignment multi-dimensional adjustment device

Abstract

A bridge alignment multi-dimensional adjustment device, which is arranged under the bridge girder body, including a position locking mechanism, an inclination adjustment mechanism, a horizontal level adjustment mechanism and a height adjustment mechanism; , the inclination adjustment mechanism includes the upper swing, the lower swing arranged below the upper swing, the super-elevation cylinder of the slope, and the inclination adjustment locking bolt fixed after the upper swing and the lower swing are adjusted. The horizontal level adjustment mechanism includes Place the hem and fix the seat plate where it is located, and the horizontal actuators arranged on both lateral sides of the hem. The horizontal actuator pushes the hem to move left and right in the horizontal direction, and the height adjustment mechanism is arranged under the hem to push the hem vertically. direction to move up and down. The invention satisfies the requirement of the alignment adjustment of the bridge girder body, especially the bridge line erection and the convenience of alignment adjustment, such as straddle-type monorail traffic track girders, which have strict requirements on the bridge alignment.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge alignment multi-dimensional adjustment device. Background technique [0002] Bridge alignment adjustment is an important process in bridge erection construction. The quality of bridge alignment directly affects the safety of bridge structures and the comfort of operating vehicles. Especially for track beams that are used as vehicle running tracks, the adjustment of bridge alignment is even more important. [0003] Straddle-type monorail traffic is a new form of modern urban rapid rail three-dimensional traffic, with low noise, strong climbing ability, small turning radius, fast and convenient, less land occupation, low cost, not restricted by terrain, and conducive to environmental protection, etc. Many advantages are a new trend in the development of urban rail transit in the future. [0004] As a two-way flexural member, the straddle-type monorail traffic track beam n...

AI Technical Summary

Problems solved by technology

[0006] Although the existing track beam alignment adjustment technology can meet the requirements for the use of straddle-type monorail traffic track beams, there are still some shortcomings in practical applications, such as complex alignment adjustment procedures, high labor intensity, and low adjustment efficiency.
