Abstract
The utility model relates to a double-column hydraulic prop with high working resistance, which belongs to special support equipment in a coal mine. The double-column hydraulic prop with high working resistance is particularly used for the mechanization support of the general gun stope and high-grade general stope working face under the hard top plate and cutting off the top plate. The utility model uses the hydraulic prop with high working resistance to support and cut off a top plate. The double-column hydraulic prop with high working resistance is fixed by an integral box-type structure and an inclined strut. The utility model has the advantages of high supporting strength and high stability. The double-column hydraulic prop with high working resistance is provided with a stone blocking plate and a tractive jack, which can realize the mechanized operation. The double-column hydraulic prop with high working resistance is characterized in that the prop is fixed by a box-type base, the connecting box and the base box are connected by the inclined strut to form a stable structure, the double-column hydraulic prop with high working resistance is provided with the movable stone blocking plate and the tractive jack, and the double-column hydraulic prop with high working resistance is operated by making use of the emulsion as the medium.
Description
This utility model is a colliery special-purpose machinery product, is used for generally adopting, big gun is adopted, high-grade common coal mining face mechanization supporting and caving.Be specially adapted to hard and tight roof in the supporting.
Mine at known general big gun, high-grade common coal mining face is along the break line place on the ancient pool, mine pressure is big, work is dangerous, the conventional fore-set of cutting that uses mainly contains intensive pin, metal column and hydraulic prop etc.But the operating personnel will be near the edge operation of roof fall district, and poor stability, labor strength is big, support process is complicated, efficiency is low, and has caused wide variety of materials consumption, can not mechanized, be unfavorable for carrying out scientific management.
The utility model overcomes above-mentioned prior art deficiency, makes a kind of Hydraulic Double pillar high workload resistance breaking-off timber, can be arranged in that general big gun is adopted, high-grade common coal mining face break line place, carries out the mechanization supporting and cuts tight roof.It is characterized in that two hydraulic props are combined with the monolithic box style substructure, and utilize liftable waste rock board, prevent that top board landslide rock from scurrying into work plane, the column cap setting can universal swing the ball pivot cap, guarantee reliable supporting under top board out-of-flatness condition, in rib one side connecting box is set, in establish the passing jack, be used for passing moving of face conveyor (scraper-trough conveyer) and breaking-off timber itself.Connecting box protects the passing jack injury-free simultaneously.For guaranteeing the stability of pillar, between connecting box and pillar seat-box, diagonal brace is set, during operation, can handle support lifting and mobile by the control valve that is arranged in the connecting box place.Hydraulic system adopts emulsion to carry out work as medium.
Because the hydraulic prop that uses has high constant-resistance characteristic, every working resistance that can reach 2400KN, directly bear the initial stage of tight roof presses and periodic weighting with it, improve supporting intensity and cut the top ability, guaranteed the safety in production of prop drawing and caving operation, security performance is superior, owing to can realize pushing and sliding, move frame, setting prop, fall operation mechanization such as post, has alleviated workman's physical labor intensity greatly.Reduced mine timber consumption, the production capacity that has improved coal-face reaches 30%-50%, and is convenient to dismounting transportation, easy to maintenance, for advantage has been created in the work plane high and stable yields.
The utility model will clearly explanation in the following example.
Fig. 1 is the breaking-off timber schematic diagram.Be fixed with hydraulic prop 1 on the base member case 9 of breaking-off timber, with the neck of two pillars hinged securement in addition, waste rock board 4 hangs on the crane span structure 3 with crane span structure 3, and connecting box 6 is hinged with base member case 9, the fixing jack 7 of passing in the connecting box, diagonal brace 5 and base member case, connecting box are hinged.Establish cap 2 at the column cap of column, utilize ball pivot to fix, can universal swing more than 10 °, according to the coal seam thickness needs, support height is the 1200--2500 millimeter, and working resistance of support can reach more than the 2400KN/ frame, the about 940--1260KN/ frame of setting load, cut top power and can reach 1600KN/, adapt to 0 °-15 ° of seam inclinations, carry out work as medium with emulsion along rice.
Claims (1)
1, a kind of breaking-off timber with the hydraulic prop roof supporting that makes up, feature of the present utility model be with two independently high workload resistance hydraulic prop 1 be fixed in the whole box style substructure 5, by crane span structure 3 that the neck of two column caps is hinged in addition, waste rock board 4 is fixed on the crane span structure 3, connecting box 6 links to each other with base member case, diagonal brace is fixed between connecting box and the base member case, is provided with in the connecting box 6 to pass jack 7, and control valve 8 is fixed on the top of connecting box.
