Problems solved by technology

The greater the tension of the chain, the greater the friction between the tensioning screw and the sliding frame. If it reaches more than 2 tons, the tensioning screw will be difficult to rotate due to excessive friction, and strong twisting will cause the screw to wear
Some use the worm gear structure to solve the problem, but the structure is too complicated and the processing cost is high

Abstract

A tensioning device for a buried scraper conveyor, comprising two symmetrically opened waist-shaped holes on two opposite outer walls of the casing, a rotating shaft arranged in the waist-shaped holes and capable of linearly moving along the axis of the waist-shaped holes, and a mounting The sprocket in the middle of the rotating shaft, two shaft seats respectively connected to the two ends of the rotating shaft, sliding frames fixed on each shaft seat, two sets of guide plates symmetrically fixed on the two opposite outer walls of the casing and The technical problem to be solved by the present invention is to provide a tensioning device for a buried scraper conveyor, which is not only easy to tension, but also beneficial to the long-term operation of the chain.

Description

technical field [0001] The invention relates to a tensioning device for a buried scraper conveyor. Background technique [0002] The main function of the tensioning device of the buried scraper conveyor is to tension the scraper chain to prevent the scraper chain from swinging and floating during operation. The tensioning device of the sealed buried scraper conveyor is used at the tail of the sealed type. Sometimes the sealed buried scraper conveyor involves a working condition with a particularly long conveying distance and a large conveying volume, so the calculated tension of the scraper chain is very Large, if it reaches more than 2 tons, the tensioning screw and the sliding plate hole will be severely worn, and the tensioning screw will not rotate. Generally, the tail tensioning device of the sealed buried scraper conveyor mainly relies on rotating the tensioning screw to drive the sliding. The frame moves backward to the tail wheel to achieve the purpose of tensioning...
