Abstract
The utility model provides a low-position coal blasting-caving hydraulic support, comprising a base which is respectively connected with the both ends of the column, a curved top beam, and a pushing beam which is positioned at the back part of the support. The front end of the top beam is in rigid hinged with a front beam which is provided with a telescopic beam. The back end of the top beam is sequentially hinged with a tail beam which is controlled by the jack of the back beam and is provided with a telescopic inserting plate. The top beam is connected with the base through a swing rod. The pushing beam is connected with the transport of the back part of the pushing beam. The support has small integral size, convenient transportation and installation, compact structure and light weight, and is an ideal support device for the coal mine blasting-caving mechanization mining face.
Description
Technical field
The utility model relates to a kind of colliery to be combined and to put the support apparatus that mechanization adopts face and particularly be applicable to the half-edge coal seams of inclination angle greater than 45 degree, and the top coal emits the low level shot firing and roof-coal hydraulic support of the working face mining of putting property.
Background technology
Hydraulic support is the support apparatus that is widely used in the colliery comprehensive mechanical coal mining, is used for the hydraulic rack structure complexity that medium and small colliery uses at present, especially is not suitable for high_dipping face and uses.
Summary of the invention
The purpose of this utility model provides a kind of solution at the hydraulic support that high_dipping face uses, and is specially adapted to the less a kind of low level shot firing and roof-coal hydraulic support that should not use the high-dipping top-coal caving face of the medium and small colliery that coal-winning machine, drift section size should not transport main equipment of coal seam thickness.
The technical solution of the utility model is: comprise the base and the curved back timber that are connected respectively by the column two ends, be positioned at the passing beam at support rear portion, its structural feature is, back timber front end rigidity is hinged with the front-axle beam that has extensible canopy, top beam rear end is hinged with the tail boom that telescopic plate is installed of tail boom jack control successively, back timber is connected by fork with base, passes beam and rear portion transporter and is flexible coupling.
Owing on front-axle beam, disposed extensible canopy, satisfy the anterior requirement of adopting blasting process of support, compare with existing general caving roof coal hydraulic support, this use is novel following advantage: 1, the anterior big gun that adopts of support is adopted coal winning technology, after blowing out, the empty top portion of extensible canopy immediate support can effectively be managed top board, satisfies the blasting process requirement; 2, supporting structure is simple, convenient transportation, and cost is low.3, caving coal coal winning technology is adopted at the rear portion, when putting coal, can adjust the size of coal discharge outlet by the motion of tail boom swing and plate, and drawing effectiveness is good.4, for making supporting structure compactness, in light weight, carriage center is apart from being designed to 1m, and the support overall dimensions is little, has made things convenient for transportation and installation.
For guaranteeing that anterior transporter normally advances, adopt push unit to pass beam, promote anterior transporter by passing beam.6, draw back slide jack for guaranteeing the stability of support, not using, and the use round-link chain will pass beam and the rear portion transporter is flexible coupling, and draws the rear portion transporter when passing anterior transporter.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 passes anterior transporter for support of the present utility model, draws rear portion transporter schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among Fig. 1, column 1, back timber 2, base 3, fork 4, tail boom 5, plate 6, front-axle beam 7, extensible canopy 8 is passed beam 9, push unit 10.Among Fig. 2, draw the soft connection device 11 of rear portion transporter.
As Fig. 1, the column two ends connect base 3 and curved back timber 2 respectively, pass the rear portion that beam 9 is positioned at support.The articulated front-axle beam 7 that has extensible canopy 8 of back timber 2 front end rigidity, front-axle beam 7 is hinged by bearing pin and back timber 2 to be integral top beam, the stroke of extensible canopy 8 is 800mm.In order to satisfy the requirement of adopting blasting process, the two ends of tail boom jack are hinged with back timber 2 and tail boom 5 respectively, hinged successively the tail boom that telescopic plate 6 is installed 5 in back timber 2 rear ends by the control of tail boom jack, plate 6 is installed in the gathering sill of tail boom 5, flexible with plate jack control plate 6, back timber 2 and base 3 are connected by fork.Push unit 10 is installed in the middle of the base, passes front and rear part transporter 12,13 by push unit.The center to center distance of support is 1m.As Fig. 2, pass beam 9 and be flexible coupling with rear portion transporter 13 usefulness round-link chains 11.
During work, pass beam 9, pass beam 9 and promote anterior transporter, be flexible coupling with rear portion transporter 13 because round-link chain 11 will be passed beam 9, so when passing anterior transporter 12, draw rear portion transporter 13 with push unit 10.Manipulate very convenient.
Claims (2)
1, a kind of low level shot firing and roof-coal hydraulic support, comprise the base and the curved back timber that connect respectively by the column two ends, be positioned at the passing beam at support rear portion, it is characterized in that, back timber front end rigidity is hinged with the front-axle beam that has extensible canopy, top beam rear end is hinged with the tail boom that telescopic plate is installed of tail boom jack control successively, and back timber is connected by fork with base, passes beam and rear portion transporter and is flexible coupling.
2, low level shot firing and roof-coal hydraulic support as claimed in claim 1 is characterized in that, the center to center distance of support is 1m.
