Description

One kind, which is adopted, fills independent compound hydraulic support
Technical field
Adopt the present invention relates to a kind of hydraulic support, more particularly to one kind and fill independent compound hydraulic support, belong to coal mine equipment Technical field.
Background technology
The method of collecting coal by the means of filling is a kind of goaf CONTROL OF STRATA MOVEMENT method, be characterized in being derived from sand outside stope, stone, slag or The fillers such as ashes, fill up goaf and the supporting role by filler reduces and crushes and be caving.It is existing comprehensive on the market Mining hydraulic bracket only provides the rack space at coal-winning machine and coal-winning machine rear portion in filling mining, all, it is impossible to provide support The safety support space in rear side goaf direction.So also limit the mode of filling mining, now can only with pipeline or The mode of ground well-digging causes coal mining enterprise's investment larger to goaf filling;And filling and exploitation are interfered, and are caused back Efficiency decline is adopted, the economic benefit of coal mining enterprise is reduce further.
The content of the invention
In order to solve the weak point present in above-mentioned technology, adopted the invention provides one kind and fill independent compound hydraulic pressure branch Frame.
In order to solve the above technical problems, the technical solution adopted by the present invention is:One kind, which is adopted, fills independent compound hydraulic support, Including support beam, support base, sliding support beam, slip bottom girder;It is fixedly connected between support beam and support base by many root posts; Support beam includes front support beam, rear support beam;One or more midfoot support beams are provided between front support beam, rear support beam; It is connected between adjacent support beam by slidably supporting beam;
Support base includes front support seat, rear support seat;One or more middle parts are provided between front support seat, rear support seat Support base;Front support seat, midfoot support seat, rear support seat respectively with front support beam, midfoot support beam, a pair of rear support beam 1 Should;It is connected between adjacent support base by sliding bottom girder;It is respectively provided between relative slip bottom girder and sliding support beam There are one or two suspension-movable hydraulic props.
Front end, the rear end of rear support seat of front support seat are provided with hydraulic jack.
The hydraulic jack of front support seat front end is connected with the drag conveyor on front side of it;Drag conveyor it is upper End is provided with coal-winning machine.
The hydraulic jack of rear support base rear end is connected with the filler conveyer positioned at rear side.
The present invention provides the supporting of long range when can be for coal mining, support space be not only present in coal-winning machine and support it Between, and it is present in the goaf direction after support, the safety coefficient and production efficiency adopted during filling can be significantly improved, So as to reduce cost of winning;The present invention can also solve tradition and adopt the contradiction for filling and mining and being interfered with filling in technique, realize Adopt and fill independently working.

Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
As shown in Figures 1 to 3, the present invention includes support beam, support base, sliding support beam 7, slip bottom girder 8;Support beam and branch It is fixedly connected between support seat by many root posts;Support beam includes front support beam 1, rear support beam 3;Front support beam 1, rear support beam One or more midfoot support beams 2 are provided between 3;It is connected between adjacent support beam by slidably supporting beam 7;Slide Support beam 7 can be done in the horizontal direction to be stretched or contractile motion.
Support base includes front support seat 4, rear support seat 6;It is provided between front support seat 4, rear support seat 6 one or more Midfoot support seat 5;Front support seat 4, midfoot support seat 5, rear support seat 6 respectively with front support beam 1, midfoot support beam 2, rear support Beam 3 is corresponded;Be connected between adjacent support base by sliding bottom girder 8, slide bottom girder 8 can in the horizontal direction with slip Support beam 7 does synchronous extension or contractile motion;One or two are provided between relative slip bottom girder 8 and sliding support beam 7 Root suspension-movable hydraulic prop 9.
Front end, the rear end of rear support seat 6 of front support seat 4 are provided with hydraulic jack 10.Wherein, before front support seat 4 The hydraulic jack at end is connected with the drag conveyor 13 on front side of it, for pushing drag conveyor 13 forward and pulling The anterior reach of compound hydraulic support;The upper end of drag conveyor 13 is provided with coal-winning machine 12;The hydraulic pressure thousand of 6 rear ends of rear support seat Jin top is connected with the filler conveyer positioned at rear side, and the rear portion for promoting compound hydraulic support moves forward and drives filler defeated Machine is sent to move forward.
The present invention concrete operating principle be:When coal-winning machine is pushed ahead, compound hydraulic support front portion is adopted for offer The part of coal space supporting is moved forward, and sliding support beam 7 and slip bottom girder 8 stretch out in the horizontal direction, suspension-movable hydraulic pressure Pillar 9 is put down, until compound hydraulic support transforms to extended conformation (as shown in Figure 2) completely;While coal-winning machine is mined, support The packing job of rear end can also be carried out simultaneously, and realization, which is adopted, fills independence;
When the packing job of back-end support completes to promote further along, suspension-movable hydraulic prop 9 is packed up, and slides branch Support beam 7 and slip bottom girder 8 do contractile motion, and traction drives complex liquid pressure support rear portion to be used to provide packing job space Part is pushed ahead (as shown in Figure 3), is completed whole flow process, is so circulated in whole recovery process.
Coal-winning machine is while being mined, and packing job is also carried out at the same time.When coal-winning machine is pushed ahead, and rear end When packing job is not completed, stent does not influence packing job while the normal propulsion of coal-winning machine is ensured;Work as filling When operation part needs to push ahead, stent collapses are close to coal-winning machine direction.Therefore, mine and fill and carry out simultaneously, and The two is separate.During coal mining, according to coal-winning machine coal cutting operating speed and packing job speed, this support can be adaptive Adjustment supporting distance, adaptive supporting scope is four times of feed size.
The present invention can be not only provided in front of support, i.e. the rack space in coal-winning machine direction, can also provide support rear, That is the support space in goaf direction;Using midfoot support beam, sliding support beam, slide bottom girder, the support of suspension-movable hydraulic prop Central space, contradiction is filled so as to relax and adopt, and reaches the purpose adopted and fill independently working, while providing necessary bar for Intelligentized mining Part.
Above-mentioned embodiment is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck The variations, modifications, additions or substitutions that the technical staff in domain is made in the range of technical scheme, also belong to this hair Bright protection domain.
