| description | The utility model relates to the technical field of hydraulic supports, in particular to a thin coal seam large dip angle light end hydraulic support which comprises a base and a top beam, one side of the top beam is provided with at least one top anti-falling assembly, and one side of the base is provided with at least one bottom anti-skid assembly. Wherein the top anti-falling assembly is configured to swing up and down in the vertical direction; the bottom anti-skid assembly is configured to swing up and down in the vertical direction. A working face top plate is extruded through the top anti-falling assembly and the first casting with the V-shaped nails, passive anti-falling of the top beam is achieved, a working face bottom plate is extruded through the bottom anti-sliding assembly and the second casting with the V-shaped nails, and passive anti-sliding of the base is achieved. The mining device is large in ventilation section, light in weight, high in supporting efficiency, high in passive anti-falling |
