Detecting device and method of train wheel set

Abstract

The application of the invention provides a detecting device and a detecting method of a train wheel set. Four image acquisition modules which are symmetrically distributed are arranged on two sides of a steel rail, and each image acquisition module comprises at least four image acquisition parts which have the same acquisition direction to detect an entire circumferential tread of the train wheel set to avoid missing detection so as to improve the detection accuracy; furthermore, the two image acquisition modules on the same side of the steel rail are different in the acquisition directions to ensure that at least one image acquisition module can obtain tread image information of a wheel when an obstruction is arranged on one side of the wheel to detect the train wheel set so as to expand the application scope of the wheel set detection, wherein corresponding image acquisition modules are automatically triggered to acquire images through two sensing modules located on two sides of the steel rail, and preset alarm information is output after the images are processed by a processor without observing in a trench artificially to simplify checking of wheel set tread defects so as to lower the workload and improve the detection efficiency of the train wheel set.

Description

technical field [0001] The present application mainly relates to the technical field of detection of wheel tread defects, and more specifically relates to a detection device and method for train wheel tread defects. Background technique [0002] In today's railway system, the wheel set, which is the main part of the running part of the vehicle, is an important link that affects the safe operation of the train. In the actual operation process, the wheel set not only bears the full weight of the train and its own weight, but also transmits The driving force and braking force between the train and the rail. In addition, the wheel set needs to bear a large static load and action force, assembly stress, thermal stress generated when the brake shoe brakes, and the frame force, guiding force, and wheel force when the curve passes. Centrifugal force on its own rotation, etc. Therefore, it is required that the wheel set must be kept in good technical condition, otherwise it will ser...

Problems solved by technology

[0005] At present, contact measurement method, acceleration detection method or optical measurement method are mainly used at home and abroad to detect wheel tread defects, which requires special safety personnel to check the wheel tread conditions one by one in the bullet train station and depot. The workload is relatively large and the accuracy is relatively high. Low, it is impossible to detect the part in contact with the rail, or even missed detection, which will leave a lot of safety hazards for the running of the train
