Abstract
The utility model discloses a coal face end hydraulic support. The coal face end hydraulic support comprises a scraper blade reversed loader tail, a scraper blade conveyor head, a base, a hinge head, a push jack, a stand column, a lifting base, a waste rock blocking plate and a top beam. The top beam is hinged to the lifting base, a whole is formed by the lifting base and the base, the hinge head is fixed on the base, the two ends of the stand column are hinged to the top beam and the base respectively, the scraper blade reversed loader tail is installed between the base and the scraper blade conveyor head, the waste rock blocking plate is fixedly connected with the top beam, and the waste rock blocking plate is located before the stand column. When the coal bed pitch changes within the ranges from 0 degree to 600 degrees, the top beam can be well attached to a top plate through the adjustment of the stand column, the waste rock blocking plate can protect flying waste rock of a coal face well, coal cut from the coal face directly falls to the scraper blade reversed loader tail from the scraper blade conveyor head. The coal face end hydraulic support has the advantages of being light, convenient to convey, install and maintain, small in occupied roadway space and beneficial to face ventilating, and the top beam adapts to the large range of the coal bed pitch change.
Description
Technical field
The utility model relates to support apparatus in coal mine, specially refers to a kind of coal-face end hydraulic support.
Background technology
Work on hand face end hydraulic support, a kind of is the parallel end hydraulic support in back timber Yu Ji lane, the deficiency that this face end support exists is, face end support back timber can only be along machine lane direction upwards or to lower swing, back timber is less to seam inclination excursion, suitable coals inclination layer uses below 150, and this face end support because of loader tail be on the base of face end support, device complexity easily causes mechanical breakdown many, and drop on the coal on face end support base, pile up many, can cause Lambton flight tail to upwarp, affect greatly Coal Transport, another shape base end hydraulic support, base is wider heavier, transportation is installed inconvenient, be unfavorable for dash, and the structure of door type base, volume is large, take tunnel area many, be unfavorable for the transportation of coal-face coal, inapplicablely under the less condition of seam inclination, use.
Summary of the invention
The purpose of this utility model is for existing deficiency, and a kind of coal-face end hydraulic support is provided, and is suitable for the termination roof timbering of 0-60o coal-face.
The technical solution of the utility model is achieved in that a kind of coal-face end hydraulic support, mainly comprise scraper blade elevating conveyor tail, scratch board conveyor head, base, articulated joint, advancing jack, column, elevating bracket, waste rock board, back timber, machine lane, back timber and elevating bracket are hinged, elevating bracket becomes entirety with base structure, articulated joint is fixed on base, column two ends respectively with back timber, base is hinged, scraper blade elevating conveyor tail is arranged between base and scratch board conveyor head, scraper blade elevating conveyor tail does not connect with base, waste rock board and back timber are affixed, waste rock board is positioned at before column, on base, be fixed with 2-4 articulated joint.
A kind of coal-face end hydraulic support that the utility model provides, 4 end hydraulic supports are installed in coal-face termination, the base Yu Ji lane of end hydraulic support is vertical, between the adjacent two hinged ears in you head hydraulic support foundations front and back, be connected with advancing jack, when end hydraulic support need to move forward, by falling frame, advancing jack pushes away frame, rise frame, advancing jack a whole set of continuous action of trying to stop people from fighting each other, can complete 4 end hydraulic supports moves forward, the back timber of end hydraulic support is vertical with coal face hydraulic support back timber, itself and elevating bracket are hinged, can swing up and down towards coal seam tendency, seam inclination changes in 0-600 scopes, back timber all can be by the adjusting of column, press close to preferably top board, the top board of coal-face is formed to good supporting, waste rock board on end hydraulic support, the cash that flies to coal-face has good protective action, ensure the safety of personnel in end hydraulic support, due between scraper blade elevating conveyor tail and scratch board conveyor head without any obstruction, the coal that coal-face is cut off, from scratch board conveyor head, directly fall on scraper blade elevating conveyor tail, efficiency of loading is greatly improved, coal passes through the reprinting of Lambton flight again, enter belt-conveying link.
The beneficial effects of the utility model are: a kind of coal-face end hydraulic support providing, and it is large, lightweight that back timber adapts to seam inclination excursion, and transportation, installation, maintenance conveniently, take lane space little, favourable face-airing.
