Abstract

The invention discloses an orthogonal detection system for a rail vehicle shaft end ground connection device wear extent, and aims to solve the problem of the orthogonal detection of the rail vehicleshaft end ground connection device wear extent. The orthogonal detection system for the rail vehicle shaft end ground connection device wear extent mainly consists of a motor (1), a sliding rail driving shaft (2), a laser level (3), a gantry crane (4), line scan cameras (5), sliding rail fixing seats (6), a sliding block (7), a workbench (8), long synchronous belts (9), a sliding rail driven shaft(10), tooth-form belt wheels (11) and a short synchronous belt (12), wherein the laser level (3) is tightly pressed into a positioning hole on the top of the gantry crane (4); two line scan cameras (5) are independently sheathed into two C-shaped grooves on the top of the gantry crane (4); and the fields of view of two line scan cameras (5) coincide and are positioned on the laser plane of the laser level (3). The invention provides the orthogonal detection system, which has the advantages of simple structure and reliable performance, for the rail vehicle shaft end ground connection device wear extent.

Description

technical field [0001] The invention relates to an auxiliary device for detection equipment in the field of traffic detection, more specifically, it is an orthogonal detection system for the amount of wear of a grounding device at the axle end of a rail vehicle. Background technique [0002] In recent years, with the vigorous development of my country's high-speed rail industry, breakthroughs have been made in various related technologies of high-speed rail trains. As an important part of the EMU grounding system, the shaft end grounding device is responsible for the important role of high-voltage current drainage. The reliability of the grounding device has become an important factor affecting the safe operation of rail vehicles, and the related test technology has also become a difficult problem to be solved. The detection of the wear amount of the grounding device at the axle end of the rail vehicle is of great significance for evaluating the performance and life of the gr...
