Abstract: In actual situation, the force of scraper and scraper chain of scraper conveyor is the pulse force, and there is severe pressure fluctuation during the working process. Key solution to the safe and stable operation of scraper conveyor is to ensure the accurate adjustment of tail chain tension and the safe locking of the scraper conveyor under the above conditions. The automatic adjustment and safety locking technology of scraper conveyor chain tension are studied.A chain tension automatic adjustment system for tail of scraper conveyor has been studied, which can automatically adjust scraper chain tension of scraper conveyor and can also be locked automatically. The system is applied in the coal mining process and the results show that the system can not only automatically adjust the tension of the chain and make it adapt to the load of scraper conveyor, but also accurately realize the automatic locking after the tension is completed. This system can help to improve the operational reliability of scraper conveyor obviously.
