Description
Technical field
The utility model relates to mine hydraulic bracket, specifically is a kind of mine hydraulic bracket that can adjust the shipping height of going into the well.
Background technology
Hydraulic support is an equipment of forming, be used for supporting and control coal mining comprehensive mechanical coal mining face roof with highly pressurised liquid as power, by Hydraulic Elements and hardware.According to " combine and adopt technical manual ", the bearing height of hydraulic support is mined with work plane and is highly adapted, its minimum bearing height is generally by the minimum Thickness Design in coal seam, the shipping height of hydraulic support equals the minimum bearing height of hydraulic support and adds the height of upper bracket transport point with flat car, so the shipping height of hydraulic support is mainly determined by the minimum bearing height of hydraulic support; Thicker as the coal seam, the minimum bearing height of required hydraulic support higher (being big mining height hydraulic support), its shipping height is inevitable higher, hydraulic support to be gone into the well and be transported to that fully-mechanized mining working is general to adopt following two kinds of methods: 1, add the go into the well driving height of haulage drift of height hydraulic support, the driving height and the shipping height of hydraulic support are complementary, so that hydraulic support is transported to coal-face, but can increase tunnel exploitation workload, strengthen the coal mining cost; 2, back timber, the caving shield of hydraulic support being pulled down on the ground disintegration transports, after support is transported to coal-face, back timber, caving shield with support assembles again, not only increased support dismounting cost, and, make that the assembling of support is difficult more because the down-hole does not have hanging device.
Summary of the invention
The utility model provides a kind of mine hydraulic bracket that can adjust the shipping height of going into the well in order to solve the big mining height hydraulic support transportation method therefor cost high problem of going into the well.
The utility model is to adopt following technical scheme to realize: the mine hydraulic bracket that can adjust the shipping height of going into the well, comprise base, back timber, the caving shield hinged with the back timber tail end, be supported in the column between back timber and base, be supported in the connection rod set between caving shield and base, be arranged at the balance jack between caving shield and back timber, back timber is provided with and is used for fixing the column column cap, and with column cap one to one, before back timber is provided with and is positioned at cap, and with the auxiliary one to one cap of cap, auxiliary cap is arranged at the horizontal bar plate by back timber, main muscle, in the space that the inclination stiffener is separated out, and auxiliary cap is provided with over against the inclination stiffener, offer the through hole that passes for the column column cap on the inclination stiffener, through hole on the inclination stiffener and auxiliary cap over against; Be provided with between back timber and the column and the column jack that resets one to one, the outer shell tail end of the jack that resets is fixed by Connection Block and back timber tail end, the piston free end of the jack that resets directly or indirectly and column be connected and fixed.
Wherein, drawstring is arranged around the home on the column, the piston free end of the jack that resets is by drawstring on column and column are connected and fixed around the home.
Perhaps, the outer cylinder of column is provided with fixture, and the piston free end of the jack that resets is connected and fixed by the fixture on drawstring and the column outer cylinder.
With the hydraulic support that possesses left and right two columns is example, the operating process of hydraulic support described in the utility model is described in detail in detail: before hydraulic support is gone into the well, the column of hydraulic support, the jack that resets are connected with emulsion power pack through control valve respectively, by emulsion power pack to the column of hydraulic support and the jack feed flow that resets; Handle control valve and rise left and right pillar, make hydraulic support about 200～300mm that raises; Simultaneously the fixture between column column cap and back timber cap is dismantled; Handle control valve then post is fallen in left column, left column is regained fully, the left column column cap breaks away from the cap on the back timber, handling control valve stretches out the reset jack corresponding with left column, make left column under the deadweight effect, with the rotation of leaning forward of base needling center, until left column column cap and corresponding auxiliary cap over against (forward leaning angle that is column is by the jack control that resets), handle control valve and rise left column, make the left column column cap pass through hole on the inclination stiffener, insert in the auxiliary cap, realize that the transposition of hydraulic support left column is supported; Continue to finish the transposition support of hydraulic support right column by said process; Two columns about handling control valve at last and falling simultaneously, and adjustment balance jack, connection rod set is rotated down, with the minimum working depth of hydraulic support (as shown in Figure 1, minimum working depth is 2400mm, and column leans forward 15 °) further reduce, reach be fit to carry out the down-hole transportation shipping height (as shown in Figure 2, shipping height is 2000mm, and column leans forward 34 °).Can transport and go into the well, after arriving the down-hole coal excavation work plane, only need to operate by the anti-process of aforesaid operations, just hydraulic support can be replied is normal support work state.
Compared with prior art, the utility model is set up auxiliary cap, make hydraulic support column move forward to the supporting point position of back timber, strengthened the forward leaning angle of column, and then make that the hydraulic support whole height can be further lower with respect to minimum working depth, and reach the suitable shipping height of going into the well, needn't increase tunnel exploitation height, exempt the program of dismounting back timber caving shield, can effectively reduce the coal mining cost.
The utility model is rational in infrastructure, and is easy to operate, and result of use is good, and shipping height is adjustable, is beneficial to reduce the coal mining cost.
