Description

Technical Field

[0001] The utility model relates to the technical field of shielding beams, in particular to a shielding beam for a joint protection type mining hydraulic support. Background Art

[0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. The mine pressure of the mining face acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the resultant force of the various supporting parts of the hydraulic support and the resultant force of the external load acting on the hydraulic support by the top plate are exactly in the same straight line, then the hydraulic support is very adaptable to the surrounding rock of this mining face. Among them, the protective beam is a kind of supporting part, which is rotatably arranged on both sides of the top seat of the hydraulic support and is transmitted to the top seat through the cylinder, rotating and unfolding along both sides of the top seat.

[0003] The shield beam has a simple structure and is mostly a rectangular plate. When the shield beam is deployed with the cylinder on the top seat, the plate is used to support the surrounding rock of the mining face. However, the two sides of the bracket are exposed, and the cylinder parts and transmission pipeline parts on the bracket are exposed. At this time, when the gravel on the surrounding rock of the mining face falls or the seeping water drips, it will cause damage to the cylinder parts. Utility Model Content
