Embodiment Construction

[0024] The present invention will be further explained below in conjunction with the accompanying drawings.

[0025] Such as figure 1 , 2 , 3 and 4, a scraper conveyor sprocket tooth wear monitoring device of the present invention includes: a top reflective patch, a vertical photoelectric sensor module, a side reflective patch, a horizontal photoelectric sensor module and a data analysis module.

[0026] The top reflective patch is installed on the top surface of the sprocket wheel. The top reflective patch is consistent with the shape of the top surface of the sprocket wheel. The vertical photoelectric sensor module includes a vertical light source and a vertical photoelectric sensor element. The vertical light source is a point light source. The light source is used to emit light to the top reflective patch, the vertical photoelectric sensing element is arc-shaped, and the vertical photoelectric sensing element is used to sense the light reflected back from the top reflecti...

Abstract

The invention discloses a device and method for monitoring wear of sprocket teeth of a scraper conveyor. The device comprises a top reflective patch, a vertical photoelectric sensor module, a side reflective patch, a horizontal photoelectric sensor module and a data analysis module; the top reflective patch The reflective patch is installed on the top surface of the sprocket wheel. The vertical photoelectric sensor module includes the vertical light source and the vertical photoelectric sensor element. The side reflective patch is installed on the top surface of the sprocket wheel tooth. The horizontal photoelectric sensor module includes the horizontal light source and the horizontal photoelectric sensor element. The analysis module includes a lower computer and an industrial computer; this method obtains the thickness data reflecting the sprocket teeth in real time through the length of the high and low level signals, and obtains the real-time wear of the sprocket teeth by comparing with the original thickness value. The invention can realize the real-time measurement of the wear amount of the teeth of the sprocket, and avoid equipment abnormality, damage and economic loss caused by tooth jumping of the chain of the scraper conveyor due to severe wear of the teeth of the sprocket.

Description

technical field [0001] The invention relates to the technical field of monitoring and safety assurance of scraper conveyor equipment, in particular to a device and method for monitoring wear of sprocket teeth of a scraper conveyor. Background technique [0002] The scraper conveyor is the main production and transportation equipment in the fully mechanized mining face of the coal mine. It undertakes the important tasks of transporting coal, providing the fulcrum for the hydraulic support and providing the walking track for the shearer. Its reliability directly affects the safety of the modern coal mine. Efficient production. [0003] The scraper chain is the most prone to failure mechanism of the scraper conveyor, and its failure accounts for about 40% of the total number of scraper conveyor failures. Once the scraper chain breaks down, the required maintenance time is long, which seriously restricts the production efficiency of large coal mines in my country. In-depth ana...
