High-speed train wheel set dynamic detection system

Abstract

The application provides a high-speed train wheel set dynamic detection system. A detection signal of the situation of a wheel set tread is acquired through an on-rail detection device which is installed on two opposite steel rail inner sides, the detection signal is transmitted by a rail side transferring device which is connected with the on-rail detection device to an on-site processing device, the detection signal is processed by a PC in the on-site processing device so as to determine a current detection result of a train wheel set, the current detection result is displayed, the running situation of a train can be adjusted by the working personnel in time according to the display content, and the running safety of the train can be guaranteed; the on-rail detection device is arranged on the inner sides of two opposite steel rails, when the on-rail detection device is installed, the steel rail does not need to be destructively modified; moreover, the shock resistance of relevant parts inside the on-rail detection device is good, and relevant information of the train can be acquired when the train runs at a high speed; in addition, the entire online detection process of the detection system for the train wheel set is automatically realized, so that the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of train wheel set detection, in particular to a high-speed train wheel set dynamic detection system. Background technique [0002] In recent years. With the rapid development of my country's economy, the requirements for train running speed and heavy load are getting higher and higher, which requires the wheelset of the train to be able to withstand a large dynamic load to ensure the safety of the train. [0003] It has been found through research that during the high-speed and heavy-load operation of the train, it is easy to cause scratches, peeling, and out-of-round phenomena on the tread of the train wheel, which will lead to a decrease in the running quality of the train, and then rapid wear and tear, and even cause the axle to break and the wheel to collapse. , causing major accidents, it can be seen that the real-time detection of the operation of the wheelset of the train, so as to deal with it in t...

Problems solved by technology

However, this detection method is only suitable for low-speed train detection, and when installing strain gauges, the original rail needs to be destroyed. Obviously, this is not allowed in high-speed railways, that is to say, the existing detection method Not suitable for online detection of wheelsets for high-speed trains

In addition, the detection system that realizes this detection method has a long debugging cycle after installation, and it is inconvenient to maintain. It is very cumbersome to replace the rail when necessary
