Problems solved by technology

However, due to the wear of the guide wheel, measurement error and positioning error, this method sometimes still cannot meet the high precision requirements.
Although there are some automatic measurement devices for wheel sets in China, they are basically contact measurement or non-contact measurement with complex mechanical movement mechanism. The main problems of the measurement method are: large measurement errors, reliability and measurement Accuracy needs to be further improved
However, the equipment imported from abroad is not only expensive, but also mostly uses trad

Embodiment Construction

[0034] The present invention will be further specifically described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0035] figure 1 It is a schematic diagram of the profile of the wheel set and the parameters to be measured. The geometric parameters of the wheel set that can be measured in the present invention include: wheel set tread wear (T1-27), axle center diameter d, wheel seat diameter d1, wheel rim thickness T, wheel diameter D, wheel rim width H, rim inner diameter D1, maximum wheel diameter difference of the same wheel set, wheel set inner distance L, three largest differences of wheel set inner distances, wheel set tread abrasion peeling, wheel rim thickness (D-D1) / 2. Except for the parameters of axle central diameter d, the largest wheel diameter difference of the same wheel set, the inner distance L of the wheel set, and the three largest differences in the inner distance of the wheel s...

Abstract

A method for automatically detecting the geometric sizes of the wheel pair for rolling stock and the scratch and stripping on the running surface of said wheel features that the step drive system is used to control the rotation of wheel pair and the structural light and visional sensor are used for said detection. Its apparatus is composed of a base, a gantry structure, vertical arm supporter, the step motor driver system installed to base, and the structural-light visional sensor installed to gantry structure.

Description

technical field [0001] The invention relates to a measurement method and a measurement device for a railway vehicle wheel set; in particular, it relates to a measurement method and a measurement device for a step-driven wheel set using structured light vision sensing Background technique [0002] The wheel set of a vehicle is an important interchangeable part on a railway locomotive, and its technical status directly affects the running safety and speed of the vehicle. In the process of overhauling wheel sets, a large number of wheel sets are removed from the locomotive every day, and there are as many as a dozen wheel set parameters to be tested, such as rim thickness, rim width, wheel diameter, and tread wear. The measurement accuracy is high, and some parameter conditions need to be diagnosed in time. These are important parameters that directly affect the operation of the vehicle, and must be detected and diagnosed in a timely and accurate manner. These measurement para...
