Abstract
The invention provides a fully-mechanized hydraulic bracket ore drawing ellipsoid control device, which belongs to the technical field of a fully-mechanized working surface hydraulic bracket, and mainly solves the problems that crushed coal filled in the back part of a rear scraper conveyer is remained in a goaf and a potential safety hazard of spontaneous combustion and ignition of the goaf exists. The fully-mechanized hydraulic bracket ore drawing ellipsoid control device comprises a hydraulic bracket and a rear scraper conveyer, and is characterized by further comprising an auxiliary hoisting platform which is located below the hydraulic bracket, is connected with the outer side of the rear scraper conveyer and is formed by a box-shaped base, an upper supporting plate and a jack, wherein one end of the upper supporting plate is hinged with the box-shaped base and a coal baffling edge is arranged on the lower side of a free end of the upper supporting plate; the coal baffling edge is engaged with the inner side of a corresponding side wall of the box-shaped base; a jack seat is hinged on the bottom of the box-shaped base; a piston head is hinged with the upper supporting plate. The fully-mechanized hydraulic bracket ore drawing ellipsoid control device disclosed by the invention adopts the auxiliary hoisting platform, so that top coal can be recycled at maximum, the recovery coefficient is effectively improved, and spontaneous combustion and ignition accidents of the goaf are reduced.
Description
Technical field
The invention belongs to the hydraulic support of top-coal saving face technical field, be specifically related to integrated caving hydraulic support ore drawing spheroid control device.
Background technology
There is at present following problem under the coal mine in the fully mechanized coal face operation process:
(1) in the Sub-Level Caving process, behind the hydraulic moving stand, the hydraulic support rear portion discharges adopts absolutely empty and can be filled with by the top coal of inbreak, wherein filling in the rear portion of rear drag conveyor and the part coal that highly is lower than the drag conveyor height in the process of bastard coal migration by gradually compacting, have no chance to flow on the drag conveyor, finally cause this part coal to be stranded in the goaf, both reduced recovery ratio, wasted resource, the potential safety hazard of Study on Protection of Spontaneous Combustion has been arranged again.
(2) when opening coal discharge outlet and put coal, broken top coal and spoil can one in the same way coal discharge outlet move, the principle of closing coal discharge outlet is namely closed for seeing cash.Larger in coal seam thickness, drawing interval is less, the dirt band layer arranged and the emitting under the conditions such as putting property is not good of top coal, the top coal easily occurring not yet all emits, rear, goaf spoil has arrived coal discharge outlet, part top coal every up, is caused Coal Loss by support, and the potential safety hazard of Study on Protection of Spontaneous Combustion is arranged equally.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, integrated caving hydraulic support ore drawing spheroid control device is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
Integrated caving hydraulic support ore drawing spheroid control device comprises hydraulic support and rear drag conveyor, is characterized in: also comprise the assistance for lifting platform, described assistance for lifting platform is positioned at the hydraulic support below, is connected with the outside of rear drag conveyor; Described assistance for lifting platform is made of box bed, mounting plate and jack, and described mounting plate one end and box bed are hinged, and gear coal limit is set below its free end; Described gear coal limit coincide with corresponding box bed inside sidewalls; Described jack base is hinged on the box bed bottom, and piston head and mounting plate are hinged.
The present invention compared with prior art has following beneficial effect:
The present invention has adopted the assistance for lifting platform, can reclaim to greatest extent the top coal, and the Effective Raise recovery ratio reduces the generation of Study on Protection of Spontaneous Combustion accident, has also increased to a certain extent the compliance of support to drawing interval.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is assistance for lifting platform structural representation of the present invention.
Among the figure: 1-spoil; 2-broken coal; 3-jack; 4-assistance for lifting platform; 5-rear drag conveyor; 6-hydraulic support; 7-mounting plate; 8-box bed; 9-gear coal limit.
The specific embodiment
As depicted in figs. 1 and 2, integrated caving hydraulic support ore drawing spheroid control device comprises hydraulic support 6 and rear drag conveyor 5, is characterized in: also comprise assistance for lifting platform 4, described assistance for lifting platform 4 is positioned at hydraulic support 6 belows, is connected with the outside of rear drag conveyor 5; Described assistance for lifting platform 4 is made of box bed 8, mounting plate 7 and jack 3, and described mounting plate 7 one ends and box bed 8 are hinged, and gear coal limit 9 is set below its free end; Described gear coal limit 9 coincide with corresponding box bed inside sidewalls; The base of described jack 3 is hinged on the box bed bottom, and piston head and mounting plate 7 are hinged.
The course of work and principle
When this invention is used, when opening coal discharge outlet and putting coal, broken coal and spoil meeting one in the same way coal discharge outlet are moved, the coal at rear drag conveyor 5 rears can drop down onto on the assistance for lifting platform 4, and final landing is to coal discharge outlet, can not be lost in the goaf, when drawing interval is less than normal, easily cause the top coal not yet all to emit, rear, goaf spoil has arrived the phenomenon of coal discharge outlet, the ore drawing spheroid has comprised the spoil of considerable part, need this moment to start jack 3, mounting plate 7 is upwards risen, the space configuration of ore drawing spheroid can be take coal discharge outlet as the center of circle, to top coal direction rotation, reduce the content of spoil in the ore drawing spheroid, improve top coal recovery rate, the gear coal limit 9 on the mounting plate keeps off spoil outside coal discharge outlet, thereby realize reclaiming to greatest extent the top coal, also increased to a certain extent the compliance of support to drawing interval.
