Device and method for measuring frictional resistance of horizontal swivel spherical hinge interface

Abstract

The invention discloses a device for measuring the frictional resistance of a horizontal swivel spherical hinge interface. The device comprises a spherical hinge structure, a load system and a traction system, wherein the spherical hinge structure comprises an upper spherical hinge structure, a lower spherical hinge structure, a positioning pin shaft and a spherical hinge positioning bracket; theload system comprises a loading plate, a plurality of supporting legs, a gradienter, a self-weight block and a self-weight block placing frame; the traction system is integrally installed on the outerside of the spherical hinge structure and comprises an angle position adjusting fixed pulley, a traction pulley, an electronic digital display tension meter, a steel strand, a traction machine and asliding way. The invention also discloses a method for testing the frictional resistance of the spherical hinge interface of the horizontal rotating body. Accurate measurement of spherical hinge interface frictional resistance of spherical hinge materials with different tonnages and spherical hinge sizes can be achieved, the method is used for guiding engineering construction, and theoretical basis and data reference are provided for actual engineering construction; the method can also be used for measuring the friction coefficients of different spherical hinge interface lubricating materials,and is used for research and development of swivel spherical hinge interface lubricating materials.

Description

technical field [0001] The invention relates to the technical field of traffic civil engineering, and more specifically relates to a measuring device and a testing method for the interface friction resistance of a horizontal swivel spherical hinge. Background technique [0002] With the accelerated development of highway and railway infrastructure in recent years, the density of my country's road network has increased significantly, and the problem of three-dimensional intersections between new bridges and existing highways and railways has become increasingly common. In order to reduce the impact of uplink bridge construction on downlink traffic (especially railway operation), more and more bridges will be constructed with horizontal rotation. In the construction process of the swivel bridge, the swivel spherical joint is the core component of the bridge swivel, which mainly plays the role of bearing the quality of the upper structure, and can also be used as a balance syst...
