Abstract

The invention relates to a pressure detection device for a track inspection robot. The device comprises a first supporting arm, a second supporting arm and a first connecting rod, a detection wheel is installed at one end of the first supporting arm, an elastic compression assembly is arranged at the other end of the first supporting arm, the first supporting arm is rotationally connected with the elastic compression assembly, a pressure sensor is arranged in the elastic compression assembly, and the middle of the first supporting arm is rotationally connected with one end of the first connecting rod; the detection wheel can rotate and walk on the surface or the rail web of a steel rail on one side; one end of the second supporting arm is perpendicularly and fixedly connected with the other end of the connecting rod, the other end of the second supporting arm is fixedly connected with the track inspection robot, and the middle of the second supporting arm is fixedly connected with the elastic compression assembly. The pressure detection device provided by the invention can accurately detect the wheel pressure change caused by the local deformation of the steel rail due to rail defect damage, material degradation and corrosion, thereby realizing the fine detection of the local deformation of the steel rail.

Description

technical field [0001] The application belongs to the technical field of robots, and in particular relates to a pressure detection device for a track inspection robot and a track inspection robot. Background technique [0002] The rapid development of high-speed railways in my country has brought challenges to the state maintenance and safety assurance of railway infrastructure. Steel rails are the main components of railway tracks and directly bear the pressure from wheel sets. Defects, damage and material degradation during long-term use affect other components. Service performance and threats to traffic safety. Rail deformation and corrosion caused by rail stress, fatigue and defects will lead to major accidents such as train derailment and overturning, which will cause casualties and huge property losses. With the increase of high-speed rail traffic density and speed , the load of the rail and the degree of extrusion and impact, the probability of rail failure and damage i...
