Description
Technical field
The utility model relates to sublevel caving hydrau lic support field, in particular to a kind of Sub-Level Caving face end support.
Background technique
Top coal caving is the important mining method of one kind of coal resources in China mechanical mining, top-coal caving face liquid
Pressure bracket is typically arranged with middle bracket and face end support, and traditional double leval jib face end support is past due to being limited by package size
Toward there is a problem of that walkway and working space are narrow, this problem has perplexed many top-coal caving faces.
Utility model content
For above-mentioned deficiency in the prior art, the utility model provides a kind of Sub-Level Caving face end support, solves biography
It unites pedestrian existing for four-bar linkage structure Sub-Level Caving face end support and the narrow problem of working space, and reduces the weight of bracket,
Cost is saved, economic benefit is improved.
In order to reach above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
A kind of Sub-Level Caving face end support, comprising: pedestal, the pedestal are equipped with tube-in-tube structure, and the tube-in-tube structure is equipped with set
Cylinder, the sleeve are made of four fixinig plates, and the sleeve part closure, the fixinig plate of the upper cartridge is mutually not attached to, described
Telescopic rod is adapted in sleeve, the upper cartridge is fastened by fixed ring, and the tube-in-tube structure side is equipped with preformed groove, described to stretch
Contracting bar top connects top beam.
Further, the quantity of the sleeve is two.
The utility model has the following beneficial effects:
The tube-in-tube structure Sub-Level Caving face end support solves pedestrian existing for traditional four-bar linkage structure Sub-Level Caving face end support
And the problem that working space is narrow, which can suitably be adjusted according to the minimum and maximum height of bracket, and make the weight of bracket
Amount reduces, and saves cost, improves economic benefit.
