Description
Technical field:
The utility model relates to coal mine machinery, and particularly hydraulic support is a kind of equidistant spacing mechanism that waits that is used for hydraulic support of its maintenance that can make when support moves frame specifically.
Background technology:
The coal in China reserves are abundant, distributed coal beds type and mining conditions difference are huge, along with expanding economy, the demand of the energy are constantly increased, the less easy mining coal seam in inclination angle reduces gradually, in recent years large-inclination-angle coal bed yield was increased gradually, but broadwall is carried out in this class coal seam, the stope overlying strata are movable violent, top board is manageability not, exploiting field equipment also takes place to glide and topple over easily, and wherein, the stability of support system (hydraulic support) is to the stable decisive role that plays of entire working surface.The hydraulic support of existing large inclination working surface departs from mutually when moving frame easily, thereby influences the stability of support system.
The utility model content:
The purpose of this utility model is to provide a kind of spacing mechanism that waits that is used for hydraulic support, described this be used for hydraulic support wait spacing mechanism will solve that the prior art hydraulic support departs from mutually easily when moving frame and the technical problem that influences the stability of support system.
The purpose of this utility model is achieved through the following technical solutions: these spacing mechanisms are located between adjacent two hydraulic supports, wherein, these spacing mechanisms comprise the crank slide bar of being located between adjacent two hydraulic support back timbers and are located at the chute structure of adjacent two hydraulic support foundations, hydraulic support back timber one side is provided with hinged seat, opposite side is provided with the gathering sill with its center line parallel, in the hinged seat of a hydraulic support back timber, be hinged with a crank, the crank other end is fixed with a slide bar, slide bar is located in the gathering sill of another adjacent hydraulic support back timber, and and this gathering sill between constitute movable along the gathering sill direction, perpendicular to the fixing sliding pair of gathering sill direction, be fixed with along the upper hopper chute of back timber center line in hydraulic support foundation one side, opposite side is fixed with the gliding groove along center line, Open Side Down for upper hopper chute, the gliding groove opening upwards, the upper hopper chute of a hydraulic support and the gliding groove of adjacent hydraulic support snap together, and this left-hand thread upper hopper chute and gliding groove together is being provided with the gap perpendicular to centerline direction.
Upper hopper chute and gliding groove all are members that cross section is rectangular in shape, the inboard, right angle of upper hopper chute and gliding groove is provided with rounding, the lower end of upper hopper chute is provided with rounding, and the upper end of gliding groove is provided with rounding, and the radius of upper hopper chute and gliding groove termination fillet is less than the radius of its inboard fillet.
The end that slide bar is positioned at gathering sill is a multidiameter, and slide bar is positioned at the height of the diameter of gathering sill one end greater than the gathering sill lateral openings.
Crank and slide bar weld together, gathering sill welding and back timber downside, upper hopper chute and gliding groove welding and base both sides.
Operating principle of the present utility model is: the back timber side at adjacent two hydraulic supports is installed the slide crank linkage, slide bar slides in gathering sill when moving frame, rotation by crank during crane compensates, but it is constant to remain adjacent stent back timber center to center distance on (perpendicular to centerline direction) in the horizontal direction.Adopt left-hand thread upper hopper chute and gliding groove acting in conjunction together between the base of adjacent two stands, the spacing base of realizing keeps center to center distance constant substantially in moving the frame process mutually, and the gap by two gathering sills compensates and move the frame deviation, prevents holding.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with the slide crank linkage at the spacing mechanism that waits that is used for hydraulic support between the back timber of adjacent hydraulic support, the back timber of a crank and a support is hinged, crank can be around its rotational, but not removable along its axis direction direction of back timber center line (just perpendicular to), the slide bar of the crank other end can slide in gathering sill, because the diameter of the end of this slide bar is greater than the height of gathering sill side openings, therefore slide bar is not removable in the direction that falls in gathering sill, therefore in moving the frame process back timber of adjacent two hydraulic supports in the horizontal direction (perpendicular to the direction of back timber center line) keep at a distance constant; Simultaneously, because the upper hopper chute of adjacent two hydraulic support foundations and the snapping effect of gliding groove, make support to move along chute direction (back timber centerline direction), and can only do trace adjustment by the gap of upper hopper chute and gliding groove perpendicular to the carriage center direction, the base of adjacent like this two stands keeps center to center distance constant substantially in moving the frame process, can also prevent the base holding.Can guarantee that by slide crank linkage and chute structure adjacent hydraulic support can not depart from mutually, has improved the stability of support system when moving frame.If be provided with rounding at the upper hopper chute of upper hopper chute and the inboard, right angle of gliding groove, the radius of upper hopper chute and gliding groove termination fillet is less than the radius of its inboard fillet, and adjacent pans adjusted when this can conveniently move frame, can holding, improve flexibility.Slide bar is positioned at the height of the diameter of gathering sill one end greater than the gathering sill lateral openings, constitutes the sliding pair along gathering sill between slide bar and the gathering sill, can not relatively move perpendicular to the gathering sill direction, and the center to center distance of adjacent two back timbers is constant when guaranteeing to move frame.
