Description
Technical field
The utility model relates to a kind of for the mining surface of low coal seam hydraulic support control device under mine, belongs to coal production auxiliary equipment field.
Background technology
Under coal mine in coal mining, along with the passing of recovery time, than be easier to exploitation in, there is not much left for the coal of high seam, and the coal reserves in the ultra-thin coal seam of coal seam thickness below 1m accounts for the significant proportion of residue coal reserves, it is one of major reason of restriction thin seam mining that existing hydraulic support takies larger space.The maximum feature of thin seam mining is exactly narrow space, especially when the girdle below a meter carries out mining operations, being obstructed in the locus, Hydraulic Elements place such as the sebific duct of hydraulic support, safety valve, reversible lock, control valve group, electrohydraulic control unit, will be squeezed, damage.Meanwhile, due to narrow space, operating personnel cannot enter the equipment damaging of changing, therefore, existing hydraulic support cannot meet in girdle produce, the requirement of maintenance, equipment replacement.
Summary of the invention
For solving this technical problem of the ultra-thin coal seam of effective exploitation, the utility model provides the hydraulic support control device of the mining surface of low coal seam of a kind of applicable working seam thickness below one meter, meet the requirement of thin seam mining to space, greatly improved mine coal carbon yield.
The technical solution of the utility model is as follows: the hydraulic support control device of mining surface of low coal seam, comprises telescopic type hydraulic support, telescopic control main valve, adjustable trestle framework, exposed reversible lock and multi-way feed flow sebific duct; Wherein telescopic control main valve is arranged on telescopic type hydraulic support below, and control main valve and move 200mm in support, controlling main valve fixed form is that slideway pin is fixed, slideway stroke is 500mm, the gear spacing of adjustable passing frame is 100mm, has four gears, and exposed reversible lock is arranged at Support frame front, multi-way feed flow sebific duct is the setting of multichannel level, and sebific duct is parallel to exploitation work plane and is hung on bracket base.
The utility model compared with prior art, uses the hydraulic support control device of the present utility model can be at work plane mining height during for 0.9m, and effective operation spatial area reaches 0.70m
2(upper wide 0.9m, lower wide 1.2m, height 0.77m), support and transporter spacing reach 200mm, hydraulic support inside and frame front space are greatly discharged, effectively reduce overall mining height, enough maintenance and the needs of production to space of ensureing, have realized the effective exploitation to one meter of following girdle.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the structural representation of mining surface of low coal seam hydraulic support control device described in the utility model.
In figure: 1-telescopic type hydraulic support, the exposed reversible lock of 2-, the telescopic control main valve of 3-, 4-multi-way feed flow sebific duct, 5-slideway.
Detailed description of the invention
As shown in Figure 1, the hydraulic support control device of mining surface of low coal seam, comprises telescopic type hydraulic support, telescopic control main valve, adjustable trestle framework, exposed reversible lock and multi-way feed flow sebific duct; Telescopic control main valve is arranged on telescopic type hydraulic support below, and control main valve and move 200mm in support, controlling main valve fixed form is that slideway pin is fixed, slideway stroke is 500mm, the gear spacing of adjustable passing frame is 100mm, has four gears, and exposed reversible lock is arranged at Support frame front, multi-way feed flow sebific duct is the setting of multichannel level, and sebific duct is parallel to exploitation work plane and is hung on bracket base.
Wherein telescopic type hydraulic support adopts ZY4800/06/16.5 type support, the maximum effectively bearing height 1650mm of this support, and minimum operational supporting height 800mm, magnification is larger, can adapt to the variation that girdle coal is thick.For adapting to thin seam mining technology requirement, support unit facility takes up room and can further reduce, and support unit facility is done to redesign layout, thereby further reduces the supporting height of working surface hydraulic support.
Wherein telescopic control main valve is arranged on set cap below, this valve group length 271.5mm, and width 340mm, height 140mm, takies the front usefull space of frame larger, and 200mm is moved in control valve group position in frame, and pedestrian's space width strengthens 200mm.Therefore, control valve group fixed form is designed to slideway pin and fixes, and slideway stroke is 500mm, and when maintenance, control valve group can pull out 500mm, pushes easy access and operation in frame when production.
Adjustable trestle framework is totally four gears, and gear spacing is 100mm.Steady pin is adjusted a gear backward, and the relative transporter distance of support widens 100mm, and before frame, effective operation space width strengthens 100mm, and the spatial altitude of top, transporter cable channel position increases 40mm, effectively avoids set cap to press transporter.
Exposed reversible lock is arranged at Support frame front, and the space in release frame ensures the normal lifting of support and maintenance repair.
Multi-way feed flow sebific duct connects establishes many logical piece horizontal arrangement, make into, return sol pipe multiple operation face and hang on main valve fore-stock base, simultaneously, use spring housing to concentrate sebific duct, increase effective operation space, avoid sebific duct to damage by pressure in frame, guarantee that walk is smooth and easy.
