320t torpedo car axle box temperature measurement system

Abstract

The invention relates to the field of detection technology and particularly to a 320t Torpedo car axle box temperature measurement system. The system comprises a detection station and a repeat station. The detection station comprises a rail edge detector, arranged on a running line of a 320t Torpedo car, and a device arranged in a machine room. The rail edge detector is connected to the device arranged in the machine room. The repeat station is used to receive the temperature of each axle box of the 320t Torpedo car detected and sent by the rail edge detector through the device arranged in themachine room, determine whether a bearing in the axle box is a hot shaft according to the temperature of each axle box, and output a prompt message when the bearing in the axle box is a hot shaft.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a temperature measuring system for a 320t mixed iron axle box. Background technique [0002] If the internal damage of the railway vehicle bearing or the uneven external force, it will cause excessive wear or damage of structural components of the bearing, jamming and other failures, which may lead to train safety accidents. The abnormal temperature rise of the railway vehicle axle box is an important symptom of the failure of the vehicle bearing. [0003] At present, on-site manual inspection and judgment are mainly used to check whether the axle box is damaged, whether the temperature of the axle box rises abnormally, and observe whether the axle box emits smoke or fire. However, when it was found that the axle box was smoking and flaming, the bearings of the axle box had been damaged due to high temperature. Especially for 320t mixed iron cars, each mixed iron car has 32 a...

AI Technical Summary

Problems solved by technology

However, when it was found that the axle box was smoking and burning, the bearings of the axle box had been damaged due to high temperature

Especially for the 320t mixed iron car, each mixed iron car has 32 axle box devices, and the number of inspection vehicles per shift is about 30. The manual inspection method has technical problems such as long detection time and untimely inspection

[0004] Therefore, there is a technical problem of how to timely and efficiently detect the temperature of the axle box of the 320t mixed iron car in the prior art
