Abstract

The invention discloses a coupling contact type magnetic flux and temperature detection probe wheel, which comprises a mounting bracket, a wheel frame, a wheel shaft, a coupling tire, probes, an angle sensor, an environment temperature sensor and a data acquisition and processing module, the coupling tire is mounted on the wheel shaft and used for abutting against an external moving part and being driven by the external moving part to rotate; the plurality of probes are uniformly arranged on the inner circular surface of the coupling tire in the circumferential direction; each probe comprises a wireless transmission module and a magnetic flux and temperature sensor module, and the magnetic flux and temperature sensor module is used for collecting magnetic flux and temperature of an external moving part; the angle sensor is connected with the wheel shaft; and the data acquisition and processing module obtains the temperature state and the stress state of the external moving part based on the detected temperature and magnetic flux. Temperature and magnetic flux data are collected and can be used for fault analysis, positioning and prediction, and reliable data support is provided for timely maintenance of external moving parts.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, and more specifically relates to a coupled contact magnetic flux and temperature detection probe wheel and a detection method. Background technique [0002] The mechanical transmission mechanism is composed of a transmission device and moving parts driven by the transmission device. When the moving parts are in circular motion, such as a conveyor belt with a metal insert inside to convey materials, a vertical elevator wire rope reciprocating up and down, an escalator handrail or an automatic When the escalator step chain circulates, if the adjustment of the moving parts is too tight, it will cause excessive friction and overheating, and this will cause the outer layer material (if any) of the moving parts to accelerate aging, cracking, wear and other consequences, reducing the use of Life, and over-tightening will also cause the brake to overheat and be more harmful, which may cau...

[0002] The mechanical transmission mechanism is composed of a transmission device and moving parts driven by the transmission device. When the moving parts are in circular motion, such as a conveyor belt with a metal insert inside to convey materials, a vertical elevator wire rope reciprocating up and down, an escalator handrail or an automatic When the escalator step chain circulates, if the adjustment of the moving parts is too tight, it will cause excessive friction and overheating, and this will cause the outer layer material (if any) of the moving parts to accelerate aging, cracking, wear and other consequences, reducing the use of Life, and too tight will also cause the brake to overheat and cause higher hazards, which may cause the temperature of the brake to rise sharply and burn out the internal components, causing brake failure and shortening the service life

[0003] At present, the maintenance of the mechanical transmission mechanism mainly adopts manual periodic repair and fault repair, that is, the staff conducts periodic inspection when there is no fault, and repairs when there is a fault. This method is an after-the-fact behavior and cannot effectively prevent the occurrence of faults. It is beneficial to avoid the occurrence of major accidents; at the same time, periodic maintenance may cause over-repair or untimely repair, resulting in a lot of time, manpower and material resources, poor effect, and high difficulty and cost of operation

In addition, since the main components of the mechanical transmission mechanism are mostly in motion during operation, it is difficult to accurately obtain their status and position
