Abstract
The invention discloses a position adjustment device for the operation valve group of a hydraulic support in a low-coal seam, which solves the problem of limited space of hydraulic supports in low-coal seams. The technical scheme adopted by the invention is as follows: the position adjustment device comprises a movable-type valve body seat, a slide rail, a square stop pin and a D-shaped pin, wherein the slide rail is arranged at the middle-rear part of the lower part of the top beam of the hydraulic support, a plurality of symmetrical location clamping grooves are opened in the slide rail, stop blocks are arranged on one surface corresponding to the location clamping grooves, of the slide rail, the movable-type valve body seat is installed at the positions of the location clamping grooves in the slide rail, location long holes are opened in the both sides of the movable-type valve body seat, and the location long holes are vertical to a plane where the slide rail is located; a pin hole is formed in one side of the square stop pin. The position adjustment device for the operation valve group of the hydraulic support in the low-coal seam disclosed by the invention has the following advantages that: the operation valve group at the original fixed position can move forwards and backwards along the slide rail, the reasonable fixed position of the operation valve group is selected on the different timbering heights of the support, thus the limited timbering space of the hydraulic support can be reasonably and effectively utilized.
Description
Technical field
The present invention relates to a kind of hydraulic support for low coal seam operating valve set fastening devices, relate in particular to a kind of hydraulic support for low coal seam operating valve set apparatus for adjusting position.
Technical background
Girdle thickness is between 0.8-1.3 rice, its mining height is low, work under hard conditions, equipment moving difficulty, particularly thin coal bed fully-mechanized mining face, when minimum mining height drops to 1. 0 m when following, operation and current all very difficult in workman's work plane, this just requires hydraulic support for low coal seam self structure 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 below, two columns of hydraulic support (arrange backward and affect support operation, arrange and affect pedestrian space forward).But because column tilts large (needing to obtain larger stroke in limited space), during whereabouts, can encounter below base or its appurtenance.
goal of the invention
Patent of the present invention belongs to hydraulic support control appliance, for solving the problem of hydraulic support for low coal seam limited space.The technical scheme that this patent adopts is that a kind of hydraulic support for low coal seam operating valve set apparatus for adjusting position, is characterized in that, comprises portable valve block, slide rail, square backing pin, D type pin; Described slide rail slide rail is located at rear in hydraulic support top beam bottom, on slide rail, have the locating groove of several symmetries and the block of the slide rail corresponding with locating groove one side, portable valve block is arranged on locating groove position on slide rail, portable valve block both sides have location slotted hole, and location slotted hole direction is perpendicular to slide rail place plane; Described side's backing pin one side is provided with pin-and-hole, and square backing pin passes the location slotted hole of portable valve block from the offside of the relative block of slide rail, and in the pin-and-hole of the described D type pin straight-bar side of being arranged on backing pin, D type pin fastens the block in slide rail locating groove outside.
Hydraulic support for low coal seam operating valve set apparatus for adjusting position according to described, is characterized in that, described portable valve block is slidably installed along slide rail.
Hydraulic support for low coal seam operating valve set apparatus for adjusting position according to described, is characterized in that, described portable valve block is installed application valve body.
The advantage of this patent is, hydraulic support for low coal seam operating valve set apparatus for adjusting position can move forward and backward along slide rail the operating valve set of original permanent position, on the different supporting height of support, select the permanent position of rational operating valve set, both can effectively dodge out workman's working space and walkway, can prevent again the location conflicts between other component of operating valve set and hydraulic support, simultaneously can be so that workman's operation can rationally effectively utilize the limited support space of hydraulic support.
