Example Embodiment

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] figure 1 It is a preferred embodiment of the automatic adjustment device for the chain tension of the scraper conveyor of the present invention.

[0026] The automatic adjustment device for the chain tension of the scraper conveyor includes an adjustment hydraulic cylinder 1, a hydraulic stabilization mechanism 2, a liquid inlet pipe interface 3 and a liquid return pipe interface 4.

[0027] The adjusting hydraulic cylinder 1 includes a right cavity 101, a telescopic rod 102, and a left cavity 103. The telescopic rod 102 is connected to the sprocket 10 of the scraper conveyor, and the scraper conveying is controlled by the telescopic rod 102. The sprocket 10 moves around the movable tailstock 11 to realize the tension or slack of the scrap...

Abstract

A chain tension automatic adjusting device of a scraper conveyer comprises an adjusting hydraulic cylinder, a hydraulic stabilizing mechanism, a liquid inlet pipe connector, a liquid return pipe connector and a shutdown locking button. The adjusting hydraulic cylinder comprises a right cavity, a telescopic rod and a left cavity. The telescopic rod is connected with a chain wheel of the scraper conveyer. The chain wheel of the scraper conveyer is controlled to move leftwards and rightwards through stretching and retracting of the telescopic rod, so that a chain of the scraper conveyer is tensioned or loosened, and the tension of the chain is adjusted. The hydraulic stabilizing mechanism is connected with the right cavity of the adjusting hydraulic cylinder, the liquid inlet pipe connector and the liquid return pipe connector. Liquid is injected into or discharged from the right cavity through the liquid inlet pipe connector or the liquid return pipe connector, so that liquid pressure in the right cavity is kept in a set range, and accordingly the telescopic rod is controlled to stretch and retract. The chain tension automatic adjusting device can guarantee that the chain of the scraper conveyer always runs at optimal tension, the service life of the chain of the scraper conveyer is effectively prolonged, maintenance frequency is reduced, and maintenance strength is reduced. Besides, production efficiency of a fully-mechanized mining face is effectively improved.

Description

technical field [0001] The invention relates to a chain tension adjustment device, in particular to an automatic chain tension adjustment device for a scraper conveyor. Background technique [0002] In the normal production process of the fully mechanized mining face in the coal mine, due to the change of the geological conditions of the coal seam, the coal cutting technology of the driver of the coal mining machine, the operation technology of the operator of the moving conveyor, and the change of the bending position of the scraper conveyor, etc. The impact, the up and down angle of the scraper conveyor and the angle of front and rear bending have been changing, and the tension of the scraper conveyor chain has also been changing. The tension of the scraper conveyor chain is constantly changing, which leads to fatigue and aging of the steel of the scraper conveyor chain, which greatly shortens the service life of the chain. Moreover, due to the continuous change of the te...
