Problems solved by technology

[0005] This type of chain blocker has many parts and a relatively complex structure. At the same time, the rotating positioning part 34 needs to match the width of the chute 6. Therefore, the shape of the chain blocker needs to increase with the increase of the slot width. At the same time, in order to ensure the strength, The section of the chain blocker increases, resulting in a significant increase in weight, which makes it very difficult to use
[0006] Similar to the chain blockers provided by patents CN201721748987.0 and CN201320854695.0, although the structure is smart and easy to use, it has the defect of insufficient strength. The structure is significantly different from the traditional chain blocker and cannot be interchanged. Need to modify the existing equipment before use

Abstract

The invention relates to the technical field of coal mine machinery, in particular to a chain stopper for a scraper conveyor. The chain stopper is formed by combining and welding a front vertical plate, a left positioning pin, a right positioning pin, a rear positioning pin, a top plate, a supporting plate and a handle, grooves which are arranged in a bilateral symmetry mode are formed in the lower end of the front vertical plate of the chain stopper, limiting hooks are arranged at the bottoms of the grooves, and a slope boss is arranged on the outer vertical face of the front vertical plate. The chain stopper is compact in structure, high in strength, light in weight, convenient to disassemble and assemble, reliable to use and capable of being conveniently used for adjusting the tensioning force of the chain of the scraper conveyor, and normal operation of equipment is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of coal mine machinery, in particular to a chain stopper for scraper conveyor, which is used for adjusting the tension of the chain of the scraper conveyor to ensure the normal operation of the equipment. Background technique: [0002] The scraper conveyor is the main transportation equipment for the fully mechanized coal mining face. The scraper conveyor is driven by the chain to drive the scraper to circulate to realize the transportation of raw coal. The normal operation of the equipment requires the chain to be properly tensioned to avoid the chain being too loose or too tight. The chain device is used to anchor the chain and is an essential tool for daily maintenance such as chain tension adjustment. When in use, the chain blocker is required to be firmly and stably combined with the chute of the scraper conveyor, and it is not allowed to loosen, which can effectively brake the scraper chain.
