Description
Technical field
The present invention relates to mining comprehensive mining machinery field, particularly a kind of beam structure and hydraulic support.
Background technology
The back timber of mining comprehensive mining hydraulic bracket mainly comprises integral top beam and two kinds of form of structure of articulated roof beam, and integral top beam is simple in structure, good reliability, back timber is stronger to bearing the balanced capacity of roof toad, support force is also larger, but flexibility is poor, can not adapt to the operating mode of top board injustice; Articulated roof beam is comparatively flexible, can adapt to multiple top board operating mode, and the size of articulated roof beam and take up room etc. adjustablely, can meet the requirement of transportation clearance, is the more beam structure form that adopts at present.
As shown in Figure 1, for a kind of existing beam structure schematic diagram, the front-axle beam 102 that it comprises back timber 101 and is articulated with back timber, general for the back timber that is hinged with front-axle beam, one end that this back timber of definable is hinged with front-axle beam is front end, contrary one end is rear end, for whole beam structure and each building block, the direction that is hinged with front-axle beam is front extreme direction, contrary direction is rear extreme direction, that is to say, front-axle beam 102 is articulated with the front end of back timber 101, the two is articulated with hinge 103, front-axle beam 102 is positioned at the place ahead of hinge 103, back timber 101 is positioned at the rear of hinge 103.For making front-axle beam 102 have certain support capacity, between front-axle beam 102 and back timber 101, be provided with support cylinder 104, the support capacity of 102 pairs of top boards of front-axle beam depends on support force and the arm of force size of support cylinder 104 substantially, restriction due to structure space and support cylinder performance, the supporting power at front-axle beam tip is generally no more than 150,000 Ns, with so little supporting power, support that the top board of top, coal-winning machine machine road is very difficult, particularly when top board is unstable or when broken, problem will be more serious, because causing the top board of top, machine road, the deficiency of supporting power sinks too early, absciss layer is broken, also can make the rib in the place ahead produce a large amount of wall cavings, the problems referred to above will further cause normally supporting of hydraulic support, top board is difficult to maintenance and affects coal production, even stop production, more serious, faceman's personal safety will be subject to larger threat.
As shown in Figure 2, for the existing beam structure schematic diagram of another kind, it mainly comprises back timber, be articulated with the front-axle beam of back timber front end, and by oil cylinder, voussoir, the governor motion that regulating block forms, be located in back timber, though the beam structure of this kind of structure can provide relatively large supporting power, but governor motion takes up room larger, particularly wherein make the oil cylinder of stretching motion, larger space will be taken in the horizontal direction, Chang Yu rear portion, its position is installed on the component such as thruster jack in back timber or spring and interferes, make the back timber internal construction can not reasonable Arrangement, so it is few that this type of beam structure adopts.
