Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The novel chain tensioner is divided into three parts, which are formed by combining three pin shafts 2 and a pressing plate 3 with a 20mm thick triangular iron plate. During use, the three parts are combined into a whole, inserted into the limiting hole in the chute 7, and the motor is used to reverse the direction to pinch off the remaining chain of the chain, thereby achieving the purpose of pinching the chain tightly. The device has the characteristics of simple structure, convenient operation, firm fixing and safe use. The specific structure is as follows.

[0027] The novel chain tensioner mainly includes a cover plate 1 and a pressing plate 3, the pressing plate 3 is used to prevent the chain stopper from disengaging the chute 7, and the pressing plate is installed in the middle of the cover plate. At least three pin shafts 2 are installed on the surfac...

Abstract

The invention discloses a novel chain tensioner, and the invention relates to a chain stop device for a scraper conveyor. It includes a cover plate and a pressure plate. The pressure plate is installed in the middle of the cover plate. At least three pin shafts are installed on the surface of the cover plate. The bottom of the chute of the scraper conveyor is provided with a pin hole matching the pin shaft. The two ends of the pressure plate are installed on the Inside the chute. The present invention has the following advantages. 1. When using, combine the three parts of the cover plate, the pressure plate and the pin shaft into a whole, insert them into the limit hole in the chute, use the motor to reverse the direction, and pinch off the remaining chain, so as to achieve the purpose of tightening the chain ; This device has been used on site for more than half a year. The maintenance workers generally report that it is safe and convenient to operate, which reduces the complicated work procedures of the operators, reduces the labor intensity of the workers, and protects the personal safety of the workers. 2. The device is easy to operate, which can help maintenance personnel reduce the time for troubleshooting and improve work efficiency.

Description

technical field [0001] The invention relates to a chain stop device of a scraper conveyor. Background technique [0002] The conveyor that is pulled by a scraper chain and uses a scraper to transport materials in a chute is called a scraper conveyor. The main structure and components of various types of scraper conveyors are basically the same, and it consists of three parts: the nose, the middle and the tail. [0003] In the current coal mining face, the role of the scraper conveyor is not only to transport coal and materials, but also the running track of the coal mining machine, so it has become an indispensable main equipment in the modern coal mining process. The scraper conveyor can keep running continuously, and the production can go on normally. Otherwise, the entire coal mining face will show a shutdown state, so that the entire production is interrupted. [0004] But the existing scraper conveyor chain tensioner is easy to wear and has a short service life, and ...
