Auxiliary device for railway bridge eccentricity measurement

Abstract

The invention provides an auxiliary device for measuring an eccentric distance of a railroad bridge. The auxiliary device comprises a fixed support, a distance meter and a fixing component. The distance meter is arranged at a first position of the fixed support. The fixing component is used for fixing the fixed support on a handrail of the railroad bridge vertically. The first position fits with an outer position of a ballast stop groove of the railroad bridge, so that the distance meter at the first position is enabled to meter a horizontal distance between the outer side of the ballast stop groove and the first position. By the aid of the auxiliary device, the horizontal distance between the outer side of the ballast stop groove of the railroad bridge and the first position of the fixed support can be metered directly by fixing the fixed support on the handrail of the railroad bridge only, a stop plate beside the handrail of the railroad bridge needs not to be opened, and besides, the auxiliary device is less influenced by wind, the eccentric distance obtained from calculation is more accurate.

Description

technical field [0001] The invention relates to a track measuring device, in particular to an auxiliary device for measuring the eccentricity of a railway bridge. Background technique [0002] When building a railway, it often encounters rivers, valleys, highways or crosses with another railway. In order for the railway to cross these terrain obstacles, it is necessary to build various railway bridges. Multiple railway bridges together form a An elevated railway. Overhead railways require that the distance between the centerline of the line and the centerline of each bridge be less than a certain range, otherwise the two piers of the bridge will be unevenly stressed, and the uneven force on the piers for a long time will seriously affect the service life of the bridge piers. Based on the above reasons, it is necessary to regularly detect the distance between the center line of the line and the center line of the bridge, so as to grasp the situation of the railway bridge in ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem in the prior art that the distance between the outer sides of the ballast grooves on both sides of the bridge cannot be accurately measured by using the eccentricity ruler, so that there is a certain error in the final result of the eccentricity of the railway bridge, the invention provides an auxiliary device for measuring the eccentricity of the railway bridge ,include:
