Infrared probe temperature measuring device

Abstract

Provided is an infrared probe temperature measuring device including a casing, a lens arranged on the casing, an infrared probe arranged in the casing, a cleaning device arranged in the casing, and two position sensors, the casing includes a body and a mount arranged outside the body, the position sensors are respectively and fixedly arranged at the upper part and the lower part of the mount, the cleaning device includes a rotary electromagnet, a rotating blade connected to the rotary electromagnet, and a hairbrush arranged on the rotating blade, the emitting directions of the position sensors face the rotary electromagnet, one end of the rotating blade is connected with the rotating shaft of the rotary electromagnet, the other end of the rotating blade is provided with a block, the rotary electromagnet drives the rotating blade to rotate around the rotating shaft to make the block of the rotating blade move ahead of the two position sensors successively, the hairbrush is arranged at the inner side of the rotating blade, and the hairbrush performs synchronous rotation along the rotating blade to clean the lens during the swing process of the rotating blade driven by the rotary electromagnet. The infrared probe temperature measuring device is high in automation and practicality, greatly prevents dust from falling to the surface of the lens, and greatly prolongs the maintenance period.

Description

technical field [0001] The invention relates to a shaft temperature detecting device, in particular to an infrared probe temperature measuring device. Background technique [0002] When the train is running, the axles and bearings rub against each other to generate heat. When there is a fault between the axle and the bearing, the friction force increases, the heat energy generated increases accordingly, and the temperature of the axle box also increases accordingly. Therefore, during the running of the train, by measuring the temperature change of the axle box, it can be determined whether the working state of the axle box is normal. In the prior art, in order to know the temperature change of the train axle box in time, it is often necessary to install a temperature measuring device on the track to detect the temperature of the axle box. [0003] However, the existing temperature measuring devices are often installed below the axle box to detect the train axle temperature...

AI Technical Summary

Problems solved by technology

[0003] However, the existing temperature measuring devices are often installed below the axle box to detect the train axle temperature from bottom to top, and the protective lens of the probe is perpendicular to the detection path of the probe, which is also inclined upward; in this way, the upper end of the protective lens is prone to dust, which seriously affects the safety of the probe. Detection precision and accuracy; and manual regular inspection and cleaning are required, the level of intelligence is not high, the workload is heavy, and human resources are wasted
