Abstract
Patent of the present invention discloses a kind of position adjustment device for operation valve group of hydraulic support in low-coal, solves the problems, such as that hydraulic support for low coal seam space is limited.The technical scheme that this patent is used is for including portable valve block, slide rail, square backing pin, D type pins；The slide rail slide rail is located at rear in hydraulic support top beam bottom, the block of several symmetrical locating grooves and the slide rail one side corresponding with locating groove is provided with slide rail, portable valve block is arranged on locating groove position on slide rail, portable valve block both sides are provided with positioning elongated hole, and positioning elongated hole direction is perpendicular to plane where slide rail；Side's backing pin side is provided with pin-and-hole.The advantage of this patent is that position adjustment device for operation valve group of hydraulic support in low-coal allows the operating valve set of original fixed position movable along slide rail, on the different supporting height of support, the fixed position of rational operating valve set is selected, can rationally effectively using the support space that hydraulic support is limited.
Description
Technical field
The present invention relates to a kind of hydraulic support for low coal seam operating valve set fixing device, more particularly to a kind of position adjustment device for operation valve group of hydraulic support in low-coal.
Technical background
Girdle thickness is between 0.8-1.3 meters, its mining height is low, work under hard conditions, equipment movement is difficult, particularly thin coal bed fully-mechanized mining face, when minimum mining height drops to 1. 0 below m, operation and current all extremely difficult in workman's working face, this requires that hydraulic support for low coal seam self structure is compact, and in the limited space of hydraulic support for low coal seam, the selection of the position of operating valve set is particularly important.Under normal circumstances, operating valve set is arranged between the back timber of hydraulic support lower section, two columns（Then influence support operation is arranged backward, and then influence pedestrian space is arranged forward）.But because column inclines larger (needing to obtain larger stroke in limited space), lower section base or its adjunct can be encountered during whereabouts.
Goal of the invention
Patent of the present invention belongs to hydraulic support control device, limited for solving the problems, such as hydraulic support for low coal seam space.The technical scheme that this patent is used for a kind of, position adjustment device for operation valve group of hydraulic support in low-coal, it is characterized in that, including portable valve block, slide rail, square backing pin, D type pins；The slide rail slide rail is located at rear in hydraulic support top beam bottom, the block of several symmetrical locating grooves and the slide rail one side corresponding with locating groove is provided with slide rail, portable valve block is arranged on locating groove position on slide rail, portable valve block both sides are provided with positioning elongated hole, and positioning elongated hole direction is perpendicular to plane where slide rail；Side's backing pin side is provided with pin-and-hole, and square backing pin passes through the positioning elongated hole of portable valve block, the D types pin straight-bar to be arranged in the pin-and-hole of square backing pin from the offside of the relative block of slide rail, the block that D type pin buckle is lived on the outside of slide rail locating groove.
According to described position adjustment device for operation valve group of hydraulic support in low-coal, it is characterized in that, the portable valve block is slidably installed along slide rail.
According to described position adjustment device for operation valve group of hydraulic support in low-coal, it is characterized in that, the portable valve block installs application valve body.
The advantage of this patent is, position adjustment device for operation valve group of hydraulic support in low-coal allows the operating valve set of original fixed position movable along slide rail, on the different supporting height of support, select the fixed position of rational operating valve set, both the working space and walkway of workman can effectively have been merged out, the location conflicts between operating valve set and hydraulic support other parts can be prevented again, simultaneously can be in order to operative, can rationally effectively using the support space that hydraulic support is limited.
