Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic supports, in particular to a protective plate device on a hydraulic support. Background Art

[0002] Hydraulic supports are structures used to control mine pressure in coal mining faces. Mining pressure acts on the hydraulic supports in the form of external loads. In the mechanical system of the interaction between the hydraulic supports and the surrounding rock, if the combined force of the hydraulic support's supporting components and the combined external force of the roof acting on the hydraulic support are aligned, the hydraulic support is well adapted to the surrounding rock.

[0003] During the coal cutting process of the coal mining machine in the coal mine, the existing hydraulic support is not equipped with a protective device. When the front guard plate rotates, there will be a gap between the front guard plate and the top plate of the top beam. Coal blocks will fly, coal blocks will be chipped, and gravel will fall from the top plate. It is easy to enter the hydraulic support of the underground equipment, causing personal injury to the miners, and damage to the components such as the columns, control valves and hoses on the hydraulic support, affecting the mining efficiency of the coal mine.
