A Ground Track Changing Test Device for Gauge Changing Bogies

Abstract

The invention relates to a ground track change test device for a variable gauge bogie, comprising: a wide gauge, a narrow gauge, a ground gauge dynamic control device, a control cabinet, two power devices, two limit trigger devices, a strain gauge Acquisition device, dynamic image acquisition device, wheel set inner distance detection device and bottom image acquisition device; the control cabinet is connected with strain acquisition device, wheel set inner distance detection device, bottom image acquisition device, dynamic image acquisition device and limit trigger device. The limit trigger device sends the position detection signal to the control cabinet; during the track change process, the dynamic image acquisition device, the bottom image acquisition device, the strain acquisition device and the inner distance detection device of the wheel set respectively collect the overall image data of the variable gauge bogie , bottom image data, wheel set track changing force data and wheel set inner distance data are sent to the control cabinet.

Description

technical field [0001] The invention relates to the technical field of vehicle gauge change, in particular to a ground track change test device for a gauge change bogie. Background technique [0002] For a long time, railway transportation has become the first choice for international combined transportation and inter-regional transportation due to its characteristics of large transportation volume, low pollution, low cost, safety and speed. However, due to political, economic, technical and other reasons, countries all over the world have maintained the status quo of multiple gauges. However, with the increase in the demand for high-speed cross-regional and transnational economic exchanges, trains need to be cumbersomely changed at different gauge line switching points. Insufficiency is becoming more and more obvious. [0003] In order to solve the problem of through running in different gauge sections, variable gauge bogie technology emerged and developed rapidly. The va...

Problems solved by technology

[0005] 1) The degree of automation is low, the labor cost is high, and the test process requires the cooperation of multiple people, which is not conducive to mass testing; 2) It is not easy to move at a constant speed. If the wheelset is stuck during the gauge change process, it cannot be stopped in time, and it is easy to cause variable track The distance from the bogie or supporting ground equipment is damaged, and the risk of personal injury is increased; 3) The test process requires multiple stops, and manual recording of the change of the inner distance of the wheel set destroys the continuity of the test, and it is difficult to save the test data
