Abstract

The invention relates to the technical field of coal mine equipment, in particular to a face guard plate for a coal mine and a forming process of the face guard plate for the coal mine. One end of the prefabricated plate in the thickness direction is fixed in the skin, and the other end is a mounting surface; the middle hinge is fixed to the mounting face and located in the middle of one end of the mounting face, and at least part of the middle hinge is located outside the skin; the two side hinges are fixed to the mounting face and located at the two ends of the middle hinge respectively, and the two ends, in the length direction, of the side hinges are at least partially located outside the skin; the longitudinal bar is arranged between the two side hinges, the length direction of the longitudinal bar is perpendicular to the two side hinges, and the longitudinal bar supports the two side hinges; and the filling foam is used for filling the accommodating space. According to the invention, the longitudinal bars support the hinges on the two sides, the bending resistance of the face guard plate is improved, the skin integrally wraps the internal parts, the face guard plate is formed, the weight is light, the structural performance is excellent, the bending resistance is high, the service life is long, and the coal mine support requirement can be met.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a coal mine guard plate and a forming process thereof. Background technique [0002] Hydraulic support is an important supporting equipment for underground coal seam mining. Before mining the underground coal seam, a certain number of wells, roadways, etc. need to be excavated. The hydraulic support supports the roof of the stope to prevent the gravel from falling and obtain a safe working space. The guard plate is an important part of the hydraulic support, which plays the role of supporting the coal wall and preventing the coal wall from splicing. The traditional guard plates are all metal components. With the improvement of hydraulic efficiency and the increasing size of the hydraulic support, the guard plate is too heavy, easy to rust and corrode, the protection effect is reduced, the safety is reduced, and the operation is difficult and inconvenient. Move and in...
