Definitions
- the invention relates to a method for estimating the tension of a chain, in particular to a method for estimating the tension of a chain of a scraper conveyor.
- the action of the scraper conveyor in the fully mechanized mining face mainly includes the sprocket chain drive and the middle slot push-slip.
- the scraper conveyor chain is subjected to various loads such as tension, self-gravity, coal-loading force and frictional resistance.
- the scraper conveyor chain is highly susceptible to the straightness of the scraper conveyor and the degree of undulation of the ground, causing failures such as chain scission, chain scission and chain scission.
- the running environment of the scraper conveyor is bad, the chain meshes with the sprocket and moves continuously in the middle slot.
- the tension of the chain is constantly affected by external factors.
- the excessive tension, too small and uneven distribution of the chain are the direct cause of the chain failure.
- the object of the present invention is to provide a simple, efficient and practical method for estimating the tension of a conveyor belt of a scraper conveyor, which solves the problem that the tension of the chain is affected by external factors, the tension of the chain is too large, too small and unevenly distributed. problem.
