The invention discloses a shield type end hydraulic bracket. A lateral protection assembly is positioned at one side, away from a tail beam, of a top beam; one end of a first lateral protecting plate is hinged to the top beam through a second rotary shaft; a second lateral protecting plate is hinged to the first lateral protecting plate through a connecting part; a telescopic cylinder is positioned under the top beam, one end of the telescopic cylinder is hinged to the top beam, and the other end of the telescopic cylinder is hinged to one end, away from a fifth rotary shaft, of the second lateral protecting plate; a lateral protecting assembly is additionally arranged at one side, away from the tail beam, of a transverse beam, is of a folding structure, and consists of the first lateral protecting plate and the second lateral protecting plate; the lateral protecting assembly is driven by the telescopic cylinder to extend, retract and fold. By adopting the optimized design, the shield type end hydraulic bracket has the advantages that the structure design is optimized and reasonable; by arranging the lateral protecting assembly with the foldable telescopic structure, the lateral protection on a mine is formed, so as to reach the attaching support on the inner wall of the well.
Description
technical field [0001] The invention relates to the technical field of mine equipment, in particular to a shielded end hydraulic support. Background technique [0002] In order to better transport, mine and protect the safety of underground workers, the end hydraulic support is a must-have support equipment for underground work. In the prior art, the side guard plate is directly hinged to the top beam in the design of the end hydraulic support, and the hydraulic cylinder is connected to the side guard plate. Driven by the hydraulic cylinder, the side guard plate rotates around the hinge point with the top beam. In the above structure, the side guard mainly protects the top, but cannot protect the side, causing potential safety hazards to the bracket components and personnel, and needs to be improved. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a shielded end hydraulic support. ...
