Abstract
The utility model relates to a rotary stripping-roadway support for a coal seam with soft coal, roof and floor. The rotary stripping-roadway support comprises a fixed frame, the fixed frame is composed of a plurality of U-shaped frames connected through fixed beams, a plurality of rotary stripping rods are uniformly arranged between the two adjacent U-shaped frames and are parallelly arranged, and gaps are reserved among the rotary stripping rods. Two ends of the rotary stripping rods are respectively penetratingly arranged on the two adjacent U-shaped frames, and the rotary stripping rods are hydraulically driven to rotate. During rotating of the rotary stripping rods, glass cutter lines on the surfaces of the rotary stripping rods keep stripping deforming coals so as to unload stress of the coals around the support, and accordingly, stress of the coals is kept released ongoing and step by step, original sections of coal roads are always kept, and requirements for safety and quality of the coals are truly met.
Description
Technical field
The utility model relates to coal mine support field of mechanical technique, is specifically related to a kind of rotating stripping excavation support of three-soft seam.
Background technology
" three is soft " coal seam refers to that coal seam is soft, the coal seam of the soft base plate industry software of top board, and the roadway support in " three is soft " coal seam is one of bottleneck of restriction mine safety production, high-yield and high-efficiency.For solving this difficult problem, by improving support material, increase supporting intensity, abolishing pseudo-end minimizing brill end amount, the release of pine side, the series of measures such as release of holing, that coal roadway support effect has obtained certain improvement, but, up to the present, fast, the support well damage of tunnel sex change speed, repair rate is high, labour intensity is heavy, coal dust flies upward the phenomenons such as work under bad environment that cause and the tunnel of therefore bringing arranged, digging is taken over the series of problems such as contradiction and still existed.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, a kind of rotating stripping excavation support of three-soft seam is provided, its rotating stripping bar is in rotary course, by surperficial glass knife mark, constantly peel off distortion coal body, with a unloading frame peripheral stress in coal bed, make stress in coal bed constantly, discharged by easy stages, remain the original section of coal road, thoroughly reach Mining Security Quality requirement.
The utility model is the deficiency solving the problems of the technologies described above, the technical scheme adopting is: a kind of rotating stripping excavation support of three-soft seam, comprise fixedly skeleton, fixedly skeleton is comprised of a plurality of U-shaped support bodys, between U-shaped support body, by clamped beam, connect, between adjacent two U-shaped support bodys, be evenly provided with a plurality of rotating stripping bars, a plurality of stripping rods are arranged in parallel, and have gap between stripping rod.
Described rotating stripping bar two ends are located in respectively on two adjacent U-shaped support bodys, and rotating stripping bar all rotates by hydraulic-driven.
Described U-shaped support body comprises two root posts, crossbeam and two cant beams, and crossbeam connects two root posts, and relative one end of two cant beams is fixedly connected with, and the other end of two cant beams is fixedly connected with the top of two root posts respectively.
Described U-shaped support body comprises two root posts and a Curved beam, and the two ends of Curved beam are fixedly connected with the top of two root posts respectively.
Gap between described adjacent two rotating stripping bars is 5～10cm.
The direction of rotation of the described rotating stripping bar that is positioned at the same side is identical, and the direction of rotation of the rotating stripping bar on the sidewall of both sides is contrary.
The surface of described rotating stripping bar has the knife mark of peeling off.
beneficial effect
Rotating stripping excavation support of the present utility model, its rotating stripping bar is in rotary course, by surperficial glass knife mark, constantly peel off distortion coal body, with a unloading frame peripheral stress in coal bed, make stress in coal bed constantly, discharged by easy stages, remain the original section of coal road, thoroughly reach Mining Security Quality requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, U-shaped support body, 2, clamped beam, 3, rotating stripping bar.
The specific embodiment
As shown in the figure: a kind of rotating stripping excavation support of three-soft seam, comprise fixedly skeleton, fixedly skeleton is comprised of a plurality of U-shaped support bodys 1, between U-shaped support body 1, by clamped beam 2, connect, between adjacent two U-shaped support bodys 1, be evenly provided with a plurality of rotating stripping bars 3, a plurality of rotating stripping bars 3 are arranged in parallel, and have gap between rotating stripping bar 3.Described rotating stripping bar 3 two ends are located in respectively on two adjacent U-shaped support bodys 1, and rotating stripping bar 3 all rotates by hydraulic-driven.The concrete shape of U-shaped support body 1 is unrestricted, can make following structure, U-shaped support body 1 comprises two root posts, crossbeam and two cant beams, crossbeam connects two root posts, relative one end of two cant beams is fixedly connected with, and the other end of two cant beams is fixedly connected with the top of two root posts respectively, also can make following structure, U-shaped support body comprises two root posts and a Curved beam, and the two ends of Curved beam are fixedly connected with the top of two root posts respectively.Gap between described adjacent two rotating stripping bars 3 is 5～10cm.The direction of rotation of the described rotating stripping bar 3 that is positioned at the same side is identical, and the direction of rotation of the rotating stripping bar 3 on the sidewall of both sides is contrary.The surface of described rotating stripping bar 3 has the knife mark of peeling off.Rotating stripping excavation support of the present utility model, its rotating stripping bar is in rotary course, by surperficial glass knife mark, constantly peel off distortion coal body, with a unloading frame peripheral stress in coal bed, make stress in coal bed constantly, discharged by easy stages, remain the original section of coal road, thoroughly reach Mining Security Quality requirement.Rotating stripping coal road support, during rotating stripping bar rotation, is peeled off coal (rock) body that knife mark peels off and can be transported processing by the drag conveyor in coal road or rubber conveyer; Finally make roadway maintenance reach dynamic equilibrium, increase work efficiency, reduce worker's labour intensity, guarantee full production.
