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 chain life and judging the chain breaking position of a scraper conveyor, and relates to the technical field of detection. According to the method, scrapers provided with magnetic blocks and Hall sensors are combined for use to detect chain breaking of the scraper conveyor, the Hall sensors are arranged on a chain wheel shell of a machine head portion and a chain wheel shell of a machine tail portion, the current time interval is judged by using the scrapers with the magnetic blocks through pulse signals of the Hall sensors, the time interval is fed back to an industrial personal computer, a processing program in the industrial personal computer further judges whether the chain breaking of the scraper conveyor occurs or not, further judges whether the chain breaking occurs on two sides or one side, and determines the specific side on which the chain breaking occurs, whether the chain breaking hidden danger exists or not and whether the scrapers have a deflection phenomenon or not can be judged in advance, if the chain breaking hidden danger and the deflection phenomenon exist, shutdown maintenance can be carried out in time, the chain breaking caused by continuous operation of the scraper conveyor is prevented, danger is avoided, and the problem that the life prediction and chain breaking monitoring of the scraper conveyor lack real-time performance is solved.
