Abstract

The invention belongs to the technical field of auxiliary devices of underground coal mine scraper conveyors, and provides a broken chain dragging device which aims to achieve the technical purposes that the dragging device used for dragging a broken chain is convenient to use and efficient, and work efficiency is improved. According to the technical scheme, a first oil cylinder and a second oil cylinder are symmetrically mounted at the front end of a machine frame and are horizontally arranged, a front end chain guiding plate and a rear end chain guiding plate are perpendicularly mounted at the front end and the rear end of the machine frame respectively, a middle chain guiding plate is perpendicularly mounted in the middle of the machine frame, a rear end chain guiding block is arranged on the side, close to the middle chain guiding plate, of the rear end chain guiding plate, a middle chain guiding block is mounted on the side, close to the front end chain guiding plate, of the middle chain guiding plate, a chain pushing frame and a chain pushing block are sequentially mounted on the side, close to the rear end chain guiding plate, of the middle chain guiding plate, and the two ends of the chain pushing frame are connected with one end of a piston rod of the first oil cylinder and one end of a piston rod of the second oil cylinder respectively. The broken chain dragging device is mainly used for underground coal mine scraper conveyors.

Description

technical field [0001] A broken chain dragging device belongs to the technical field of auxiliary equipment for scraper conveyors in coal mines. Background technique [0002] In the process of conveying underground in coal mines, the chain of the scraper conveyor often breaks. When the chain is connected later, the dragging of the broken chain becomes an extremely heavy physical labor, which affects the working efficiency of the coal mine. . Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and the technical problem to be solved is to provide a convenient and efficient device for dragging broken chains and improving work efficiency. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is a broken chain dragging device, including a frame, a rear end chain guide plate, a rear end chain guide block, a middle chain guide plate, a middle chain guide block, a push c...
