Description
Technical field
The present invention relates to comprehensive mechanical coal mining face timbering equipment under the coal mine, particularly hydraulic support specifically is a kind of side arm of support integratedization of paste body filling hydraulic support.
Background technology
Along with the increase of mining depth, the raising of the increase of village migration cost and filling technique technological level, the filling mining technology has become flourish gesture.For improving coal mining efficient, extensively adopt filling and support one hydraulic support at present, the front end supporting is convenient to mine, and filling is convenient in the rear end supporting.China's utility model patent " filling mining hydraulic support " (February 6 in 2007 applying date order; Notice of authorization order on January 16th, 2008, notice of authorization CN 201007216Y) manual discloses a kind of hydraulic support, and this support is a monolithic; Front end is the coal mining supporting, and the rear end is the waste filling supporting.Because it is more more convenient than waste filling that lotion fills body, filling body is simpler, has therefore also occurred the paste body filling support at present.China utility model patent " formwork support with filling behind support " (February 24 2009 applying date; July 22 2009 notice of authorization day; Notice of authorization CN 101487395A) the disclosed hydraulic support of manual, its rear portion is provided with waste filling mechanism and filling template mechanism, can realize paste body filling; But this hydraulic support still adopts overall structure; Because need certain setting time behind the paste body filling, make the coal-winning machine of front end must wait for lotion solidify after just removable if moving frame then can destroy its filling structure this moment.And for the ease of moving frame, the filling support of frame form before and after having occurred, side arm and after-frame can move frame respectively like this, needn't move simultaneously, can improve the efficient of coal mining.Existing support adopts four post braced structures forms, if when the height of front and back two root posts is inconsistent, causes back timber unstable; And the filling and support support of front and back frame form when descending before and after it quadric chain of frame be folded between back timber and the base; The quadric chain of front and back support may interfere when shrinking; The quadric chain of frame is interfered for fear of front and back; Make support occupy bigger space usually, to such an extent as to can not reduce support as far as possible.
Summary of the invention
The object of the present invention is to provide a kind of side arm of support integratedization of paste body filling hydraulic support; The side arm of described this support integratedization of paste body filling hydraulic support will solve the filling support four post braced structuress that adopt in the prior art more, causes the unsettled technical problem of back timber easily.
The objective of the invention is to realize through following technical scheme: this support integratedization of paste body filling hydraulic support by side arm with after be configured to; Side arm comprises one-level wall supporting, secondary wall supporting, back timber, front column, rear column; Last connecting rod, front rod, back link and base, the hinged in twos formation four-bar mechanism of last connecting rod, front rod, back link and base, last small end and back timber middle part are hinged; Front column and rear column upper and lower side are hinged with back timber and base respectively; This side arm comprises two front columns and a rear column, and two front columns are positioned at base front end both sides, and rear column is positioned in the middle of the base rear end; Last connecting rod is the H type, and rear column is arranged between two branches of connecting rod bottom.
Front rod is the Y type, and the bottom of two branches of connecting rod is hinged respectively on two branches of Y type front rod and the H type, and Y type front rod lower end and base are hinged.
On base, be welded with along main muscle in its length direction, be provided with distance between the main muscle in two, base is standard-sized sheet crotch structure; Main muscle front end and Y type front rod lower end are provided with bearing pin in two, on base, also are provided with middle otic placode, and middle otic placode is fixedly connected with base; Offer groove in Y type front rod lower end; Middle otic placode is embedded in this groove, is provided with distance between middle otic placode both sides and this groove two medial surfaces, and the bearing pin of Y type front rod lower end is arranged in the earhole of middle otic placode.
Rear column is located on the base through needling, and needling passes through shim on base.
In top beam rear end, be arranged with extensible canopy and extensible canopy jack, extensible canopy jack two ends are hinged with back timber and extensible canopy respectively, are provided with the sliding pair along its length direction between extensible canopy and the back timber.
Be welded with a curved bent plate in two between the main muscle rear end.
The last seamed edge of two main gussets of chassis outer side is provided with chamfered transition.
Connecting rod two branch's lower end interior plates lean on last seamed edge to establish chamfered transition on the H type.
Main gusset thickness is 40mm. in the base
The present invention compares with prior art, and its effect is actively with tangible.The side arm of support integratedization of this paste body filling hydraulic support adopts three column supporting structurals of two front columns in front, a rear column; Constitute three-point support structure, the unsettled situation of back timber when former and later two column height are inconsistent when avoiding adopting four columns; Because shelf structure form before and after this hydraulic support adopts, side arm is used for the supporting bank, and therefore mine after-frame supporting filling area and filling can be carried out simultaneously incessantly, has improved coal mining efficient; Last connecting rod is the H type, and connecting rod can interlock on the after-frame when falling frame like this enters on the H type between two branches of connecting rod, avoids the four-bar mechanism of front and back support to interfere, and can reduce support height as far as possible, is convenient to regulate support height.Owing to only adopt one, between the needling of rear column and base, backing plate is set, it is even to make needling pass to the pressure of base, strengthens supporting capacity.Because this side arm rear portion also is connected with an after-frame, therefore extensible canopy is set at top beam rear end, this extensible canopy can stretch out backward, and supporting is carried out in the zone between the frame of front and back.Middle otic placode is set on base, is used to connect the front rod lower end, can strengthen the supporting capacity that goes up connecting rod lower end bearing pin.Arc bent plate of welding between the main muscle rear end in the base two, the intensity of main muscle in the enhancing is to strengthen the intensity of full easy opened base.The last seamed edge of two main gussets of chassis outer side is provided with chamfered transition, scratch lotion carrier pipe when preventing to move frame.
