Problems solved by technology

[0003] At present, the jacking device of the top-coal caving hydraulic support mostly adopts a vertical structure, which makes the lateral support capacity of the top-coal caving hydraulic support limited and the stability is poor, and when the top-coal caving hydraulic support is loaded, the window coal material lacks corresponding Coal breaking mechanism, which makes the coal port prone to clogging

Abstract

The invention relates to the technical field of top coal caving, in particular to a light top coal caving hydraulic support. The light top coal caving hydraulic support comprises a base, an adjustingframe, a crushing mechanism and a driving mechanism; the adjusting frame is arranged on the upper side of the base, the crushing mechanism and the driving mechanism are arranged on the adjusting frame, and the crushing mechanism is driven by the driving mechanism; and four front hinged supports and two rear hinged supports are arranged on the base, each front hinged support is hinged to a main jack, and a cross-shaped sliding rail is arranged above the base. According to the light top coal caving hydraulic support, the four inclined main jacks are arranged below the cross-shaped sliding rail,the main jacks are connected with the cross-shaped sliding rail in a sliding mode through first sliding blocks, two inclined auxiliary jacks are arranged below a transverse sliding rail, the auxiliaryjacks are connected with the transverse sliding rail in a sliding mode through second sliding blocks, and when the main jacks and the auxiliary jacks stretch out and draw back, the sliding blocks canbe driven to move along the sliding rails, so that the cross-shaped sliding rail and the transverse sliding rail move.

Description

technical field [0001] The invention relates to the technical field of top-coal caving, in particular to a light-duty hydraulic support for top-coal caving. Background technique [0002] The top-coal caving hydraulic support is developed on the basis of the common long-arm working face hydraulic support. It has the same functions in controlling basic items, maintaining direct jacking, self-moving and pushing conveyors, but the top-coal caving mechanism and support are affected by The functions of power, head support, dust reduction and other aspects are different. The basic requirements for the selection of the top-coal caving hydraulic support: the top-coal caving support has a hydraulically controlled coal discharge mechanism, and the hydraulic control performance of the coal discharge mechanism is required. Open and close Rapid, reliable, large coal discharge port, not easy to block, and has a good spray dust suppression device; the coal discharge mechanism must have stro...
