Description
Technical field
The utility model relates to coal mine machinery field, the forestope that particularly a kind of mining excavation is used.
Background technology
In the time of the headwork of colliery, forestope is for strengthening roof control, prevent roof fall accident play a part very important, popularize large section support technology from group company in 2000 in an all-round way at each subordinate's mine, section clear height 4150mm, clear span 5700mm, adopts anchor rete cord spray+36U steel bracket+large column supporting.When large section driving back open-assembly time long, tunnel is high, and roof fall casualty accident easily occurs.Therefore, must divide and carry out temporary lining leading empty top.Traditional forestope is all the problem of focusing on having solved " protecting " substantially, and the problem of " propping up " is but never resolved, and its use is unsatisfactory, and therefore, the improvement of forestope is the technical problem of needing at present solution badly.
Summary of the invention
For above-mentioned situation, for solving the defect of prior art, the object of the utility model is just to provide the forestope that a kind of mining excavation is used, and can effectively solve the technical problem that forestope can protect and can prop up.
The technical scheme that the utility model solves is, comprise steel pipe, steel bushing and card cable, steel bushing has individual being sleeved on steel pipe, form beam body, on each steel bushing, be welded with 36U card cable, form passing and the fixed structure of beam body, beam body front end 400mm place and 600mm place are respectively equipped with boring, in boring, be welded with the cylinder nut of interior rib-loop, rib-loop leading screw perpendicular to beam body is housed in each nut, the lifting structure that forms rib-loop leading screw, rib-loop leading screw top is provided with anchor cable pallet, and what formation rib-loop leading screw pushed up with sky contacts supporting and protection structure.
The utility model is made simple, and cost is low, practical, applicable to steel I-beam and U-shaped girder steel, is the innovation on forestope.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1, the utility model comprises steel pipe, steel bushing and card cable, steel bushing 4 has 2 to be sleeved on steel pipe 1, form beam body, on each steel bushing 4, be welded with 36U card cable 6, form passing and the fixed structure of beam body, beam body front end (left end) 400mm place and 600mm place are respectively equipped with boring, in boring, be welded with the cylinder nut 5 of interior rib-loop, rib-loop leading screw (support bar) 3 perpendicular to beam body is housed in each nut 5, the lifting structure that forms rib-loop leading screw, rib-loop leading screw 3 tops are provided with anchor cable pallet 2, and what formation rib-loop leading screw pushed up with sky contacts supporting and protection structure.
In order to ensure result of use, described steel pipe 1 is long 4000mm, the circle that diameter is 3 inches.
Described steel bushing 4 is long 150mm, the circle that diameter is 4 inches.
Described anchor cable pallet 2 face sizes are 200mm × 200mm.
Described beam body forms side by side by 3 groups, array pitch 600mm, distance of stretch out and draw back 2.4m.
Can be found out by said structure, the main body of beam is fitted together by 3 inches of long steel pipes of 4000mm and two sections of 150mm, 4 inches of steel pipe sockets, on the steel pipe of two sections 4 inches, weld 36U card cable, realize the passing of beam and fix, the total quality that steel pipe has been realized beam is little, simple to operate light; Because the spacing of canopy is 600mm, bolt interval 600mm × 600mm, therefore the cylinder nut (length is identical with tube outer diameter) of rib-loop in welding in hole with the boring of 600mm place at the front end 400mm place of beam, be mated with two trapezoidal rib-loop leading screws with handle, realize the lifting of support bar, leading screw top is installed anchor cable pallet (face size 200mm × 200mm) and is realized support bar and empty direct contact of pushing up, and can regulate the intensity of roof supporting by elevating screw.A set of forestope is made up of 3 groups of single-beams, array pitch 600mm, and 2.4 meters of distance of stretch out and draw backs, can be leading screw in the steel pipe as for body pillar after dismounting, is convenient to dismounting and carrying, is convenient to dismounting and carrying.
The utility model is made simple, and cost is low, practical, applicable to steel I-beam and U-shaped girder steel, makes the little passing of forestope total quality and dismantle lightly with hollow steel pipe as main body, has alleviated workman's labour intensity; Be connected with U-shaped canopy with 36U card cable make to be connected and fixed firm, intensity is large, good stability; 36U card cable movable sleeve can be according to canopy apart from arbitrarily adjusting, and collapsing length is flexible; There is good popularization and practical value for work planes such as down-hole anchor cable net spray supportings, there is good economic and social benefit.
