Abstract

The invention discloses a gangue stopping device, which comprises a base, a first rotating oil cylinder, a rocker arm, a retractable sleeve, a retractable oil cylinder, a protection net, a face oil cylinder and a face guard, wherein one end of the first rotating oil cylinder is hinged with the base, the other end of the first rotating oil cylinder is hinged with the position of the rocker arm adjacent to the middle, one end of the rocker arm is hinged with the base and the first rotating oil cylinder is used for controlling the rocker arm to rotate within a horizontal plane; the retractable sleeve is sheathed on the rocker arm, one end of the retractable oil cylinder is connected with the rocker arm, the other end of the retractable oil cylinder is connected with the retractable sleeve and the retractable oil cylinder is used for controlling the retractable sleeve to extend and retract along the rocker arm; the face guard is hinged with the front end of the retractable sleeve, the upper side of the protection net is connected with the retractable sleeve and the lateral side of the protection net is connected with the face guard; and one end of the face oil cylinder is hinged with the position of the retractable sleeve adjacent to the front end and the other end of the face oil cylinder is hinged with the position of the face guard adjacent to the middle part. The gangue stopping device has the advantages that the automatic extension and the automatic retraction of the protection net can be realized, the protection strength is improved and the safety in mining operation is improved.

Description

technical field [0001] The invention relates to mining operation safety protection technology, in particular to a gangue blocking device. Background technique [0002] In mining operations, hydraulic supports are usually used to support and control the roof of the fully mechanized mining face, isolate the goaf, and prevent gangue from entering the mining face and the scraper conveyor. [0003] During coal mining, the gangue on the fully mechanized mining face with a large inclination angle will roll down, easily injuring operators or coal mining equipment. [0004] In order to solve the above problems, in the prior art, when working on a fully mechanized mining face with a large inclination angle, a metal mesh or a wire rope mesh is manually erected as a protective mesh to protect operators or coal mining equipment. [0005] However, the existing manually erected protective nets have low strength, are easily damaged, and are difficult to achieve full-section closure, result...
