Embodiment Construction

[0027] The embodiment of backfilling hydraulic support in the present invention is such as Figure 1-7 shown. The backfill hydraulic support includes a hydraulic system 32, and the backfill hydraulic support also includes a top beam and a base 1. The top beam includes a front top beam 2 and a rear top beam that are separately arranged. The front top beam 2 and the rear top beam are hinged, and the rear top beam adopts Segmented structure, the rear top beam is composed of two segments, the two segments are the front beam section 3 and the rear beam section 25, and the front beam section 3 and the rear beam section 25 are fixed by a detachable fixing structure, which can be detachably fixed The structure includes a first detachable pin shaft 26 and a second detachable pin shaft 27 arranged at intervals. There are two ways to use the detachable fixing structure in this embodiment during transportation. The first is to remove the second detachable pin shaft 27. After the rear bea...

Abstract

The invention relates to a backfilling hydraulic support and a rock blocking component thereof.The backfilling hydraulic support comprises a base, the rock blocking component is arranged at the rear end of the base, comprises a fixed retaining plate and further comprises a movable retaining plate adjustable in up-down position relative to the fixed retaining plate and a height adjusting mechanism for adjusting height of the movable retaining plate in up-down direction, and each of the fixed retaining plate and the movable retaining plate is provided with a backward rock blocking face for blocking rock.The height of the movable retaining plate is adjusted to adjust overall height of the rock blocking component so as to adapt to different rock filling heights.

Description

technical field [0001] The invention belongs to support equipment for coal mining working faces in underground coal mines, in particular to a backfill hydraulic support and gangue retaining components. Background technique [0002] The hydraulic support is a device for supporting and covering the roof of the working face during the coal mining process. In the process of coal mining, waste such as gangue will be produced, and a large amount of gangue will occupy land and cause pollution to the land. The backfill hydraulic support is a new type of hydraulic support. A conveyor is suspended from the rear end of the top beam of the backfill hydraulic support. The conveyor transports the gangue to the goaf to fill the goaf. The backfilling hydraulic support not only has the basic functions required by the traditional hydraulic support to cover coal mining, but also has the function of using gangue to fill the goaf. The use of gangue to fill the goaf can not only reduce the accu...
