Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of intelligent monitoring of idler rollers, and in particular to a monitoring assembly, an idler roller working state monitoring device and an intelligent idler roller equipment. BACKGROUND

[0002] The belt idler roller is a core component of the belt conveyor, and is used for bearing and guiding the conveyor belt. Since the belt conveyor is often used in harsh environments such as high dust and high humidity, the belt idler roller is prone to wear and failure, which seriously affects the reliability of the belt equipment and the safety of the production work. At present, the working state of the belt idler roller still mainly depends on manual inspection, and it is difficult to timely and accurately find the idler roller failure. Therefore, it is particularly important to monitor the working condition of the idler roller in real time during the operation of the belt conveyor. The introduction of the belt idler roller that can indicate the rotating state will improve the safety and stability of the belt conveyor, and at the same time reduce the labor burden.

[0003] At present, the patents about the idler roller working state detection device, such as the authorized number CN220392376U "Idler with wireless transmission and intelligent monitoring function" proposes an idler that uses piezoelectric material to generate electricity for the sensor and data transmission, and does not mention the structure and measurement method of the idler speed sensor; the authorized number CN112678465B "Idler type intelligent detection equipment and method with environmental monitoring and self-checking function" proposes a device that uses a vane type piezoelectric array generator to provide power for the sensor inside the idler, and analyzes the working state of the idler through the sensor data, but this patent only describes the specific structure and working mode of the vane type piezoelectric array generator, and does not explain the speed measurement device and method; the application number 202410419355.8 "Belt conveyor self-driven intelligent monitoring integrated idler and monitoring method" uses the rotation of the idler shell to repeatedly roll and press the piezoelectric element to generate electricity, but the structure and detection method of the idler working rotation state detection part are relatively general.
