A Coal Mine Scraper Conveyor Chain Drive Speed ​​Limiting Positioning Device

Abstract

The invention discloses a speed-limiting positioning device for chain drive of scraper conveyor for coal mines, comprising a motor, a fixing seat, a chain main body and a fixing cylinder. A reserved groove is arranged through the middle of the fixing seat, and the middle of the reserved groove A fixed cylinder is installed in a snap fit, and there are two fixed cylinders. The top of the fixed cylinder on the left is connected with a motor, and the top of the motor is connected with the rotating shaft. The baffle is on the left and right sides of the rotating gear. There is provided, and the outer part of the rotating gear and the chain main body are meshed and connected with each other, and the chain main body is arranged on the outer surface of the fixed seat. When the scraper conveyor chain drive speed-limiting positioning device for coal mine is in use, it can well control the moving speed of the chain, so as to ensure that the entire chain can be well controlled when the whole chain moves at overspeed. Therefore, the phenomenon of breakage caused by the overspeed movement of the chain will not occur.

Description

technical field [0001] The invention relates to the technical field related to coal mining, in particular to a speed-limiting positioning device for chain transmission of a scraper conveyor used in coal mines. Background technique [0002] In the existing market, when people mine coal mines underground, they generally need to use scraper conveyors. The scraper conveyors can achieve the effect of equal transportation of the mined coal mines, so as to reduce the work of the staff. The phenomenon of quantity occurs, and when the coal mine is transported through the scraper conveyor, because the auxiliary work of the chain is needed, the following problems still exist when the chain is used on the scraper conveyor; [0003] When the traditional chain moves to drive the scraper to move, the chain often moves too fast, and when the chain moves fast, the chain often breaks, which affects the normal operation of the entire conveyor. And when the chain is moving between the gears, t...

Problems solved by technology

[0005] The purpose of the present invention is to provide a speed-limiting positioning device for chain transmission of a scraper conveyor used in coal mines to solve the problem that the chain movement speed often occurs when the scraper conveyors on the market currently on the market are carrying out coal transportation. The phenomenon of breaking occurs too quickly, the movement speed of the chain cannot be well controlled, and when the chain is in use, the problem of slippage often occurs
