Abstract
The utility model provides an underground hydraulic support device for a coal mine. According to the technical scheme, the device comprises a plurality of supports which are arranged in sequence, wherein a main valve area is arranged on one side of each support; an upright post on which a hydraulic control valve piece is fixed is arranged in the middle of each support; a main valve of the main valve area controls the hydraulic control valve piece on the upright post; a small hydraulic control valve area is arranged on the other side of each support; and a hydraulic control valve of the small hydraulic control valve area controls the main valve on adjacent support. Each support is controlled by adjacent support, the device has a simple structure and small external diameter and works reliably, and hydraulic control pipelines are concentrated and straightened out.
Description
Technical field
The utility model relates to a kind of underground hydraulic support frame device for the colliery.
Background technology
At present, in the underground mining of colliery, generally use hydraulic support, and mostly the maneuverability pattern of hydraulic support mainly is this manipulation, operating personnel stand in this and upper move forward along with the reach of support, fall frame at support, draw and move past in the journey, and the coal dust of inbreak, broken coal, broken cash not only affect sight line, also affect personal safety, have great potential safety hazard.This is the existing weak point of prior art.
Summary of the invention
The purpose of this utility model, be exactly for the existing deficiency of prior art, and provide a kind of technical scheme of the underground hydraulic support frame device for the colliery, the hydraulic support of this scheme belongs to adjacent frame and handles control, and is simple in structure, the hydraulic control pipeline concentrates and external diameter is less, pipeline is made in order, reliable operation.
This programme is achieved by the following technical measures: a kind of underground hydraulic support frame device for the colliery, comprise a plurality of supports that set gradually, the characteristics of this programme are: a side of described support is provided with the main valve district, middle part at support arranges the column that is fixed with the hydraulic control valve member, hydraulic control valve member on the main valve control column in described main valve district, opposite side at support is provided with small-sized control hydraulic valve district, and the control hydraulic valve in described small-sized control hydraulic valve district is controlled the main valve on the adjacent support.The small-sized control hydraulic valve district of a described support is communicated with by high-pressure rubber pipe with the main valve district of another adjacent support.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because the main valve district is arranged in this scheme, can effectively control the hydraulic control valve member, is beneficial to and finishes underground work; On support, also be provided with the main valve district that small-sized control hydraulic valve district can control adjacent next support, thereby realize adjacent frame manipulation control hydraulic support, realize the unlatching of the large flow main valve of Small Flow Control hydraulic control system or close, the support group that a plurality of like this supports form can be finished more workload.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is the small-sized control hydraulic valve of the second support district, and 2 is the second support main valve district, 3 is high-pressure rubber pipe, and 4 is the small-sized control hydraulic valve of the first support district, and 5 is the first support main valve district, 6 is the second bracket upright post, 7 is the first support hydraulic control valve member, and 8 is the second support hydraulic control valve member, and 9 is emulsion pump, 10 is emulsion box, 11 is the first bracket upright post, and 12 is the first support, and 13 is the second support.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing, this specific embodiment comprises two supports that set gradually, one side of the first support 12 is provided with the first support main valve district 5, middle part at the first support 12 arranges the first bracket upright post 11 that is fixed with the first support hydraulic control valve member 7, the main valve in described the first support main valve district 5 is controlled the first support hydraulic control valve member 7 on the first bracket upright post 11, opposite side at the first support 12 is provided with the small-sized control hydraulic valve of the first support district 4, the control hydraulic valve in the small-sized control hydraulic valve of described the first support district 4 is controlled the main valve on the second support 13, one side of the second support 13 is provided with the second support main valve district 2, middle part at the second support 13 arranges the second bracket upright post 6 that is fixed with the second support hydraulic control valve member 8, the main valve in described the second support main valve district 2 is controlled the second support hydraulic control valve member 8 on the second bracket upright post 6, is provided with the small-sized control hydraulic valve of the second support district 1 at the opposite side of the second support 13.The small-sized control hydraulic valve of the first support district 4 of described the first support 12 is communicated with by high-pressure rubber pipe 3 with the second support main valve district 2 of the second support 13, in addition, carry the used liquid of hydrodynamic pressure for main valve district and the small-sized control hydraulic valve district of each support with the emulsion box of emulsion pump in addition.
