Problems solved by technology
[0002] At present, in the process of using the scraper conveyor in the coal mine for transportation, the scraper conveyor may break the chain, which not only affects the working efficiency of the underground mining work of the coal mine, but also endangers the safety of the underground workers. There are many problems in engineering practice. Disadvantages, if it is monitored manually, real-time performance cannot be achieved, and it can only be judged when the disconnection phenomenon occurs, and it cannot give early warning to the current work when the disconnection phenomenon does not occur. It lacks initiative. Once the disconnection occurs, Maintenance takes a lot of time, resulting in a large waste of time and reducing the safety and reliability of underground mining work in coal mines

Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0028] This embodiment provides a method for predicting the service life of a chain of a scraper conveyor and identifying a broken chain position. In this method, a magnetic block is installed on the scraper of the scraper conveyor, and a magnetic block is installed on the head and tail of the scraper conveyor Hall sensors are arranged on the left and right sides of the surface, and the chain break detection of the scraper conveyor is performed by using the time interval when the adjacent scrapers with magnetic blocks pass through the Hall sensors.
[0029] Such as figure 1 and figure 2 As shown, two Hall sensors are installed on each side of the outer surface of the pr...

The invention provides a method for predicting the service life of a chain of a scraper conveyor and judging a broken chain position, and relates to the technical field of detection. The method of the present invention utilizes the combined use of the scraper installed with the magnetic block and the Hall sensor to detect the broken chain of the scraper conveyor. The scraper passes through the pulse signal of the Hall sensor to judge the current time interval, and feeds back the time interval to the industrial computer. The internal processing program of the industrial computer further judges whether the scraper conveyor is broken, and further judges whether it is double-sided or single-sided. Side chain breakage, on which side the unilateral chain breakage phenomenon occurs, can predict whether there is a hidden danger of chain breakage and whether the scraper has deflection. The continuous operation of the scraper conveyor will cause chain breakage and cause danger, which solves the problem of lack of real-time performance in life prediction and chain breakage monitoring of scraper conveyors.
