Fig. 4 is that fully mechanized workface is taken a step from the hydraulic scheme that moves cantilever timbering.
Among the figure: 1-back timber, 2-column, 3-base, 4-two linkages, 5-pass jack, 6-base, 7-column, 8-back timber, the anti-down jack of 9-, 10-extensible canopy, 11-longeron, 12-crossbeam, 13-crossbeam, the flexible jack of 14-, 15-operation valve group, 16-control valve.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Fully mechanized workface of the present invention is shown in Fig. 1～3 takes a step from the structure of moving cantilever timbering.It mainly by flexible forestope support, passing and anti-down jack, take a step to form from moving the supporting bracket three parts.
1. flexible forestope holder part: form by the left and right sides and intermediate portion that structure is identical; Each side is made of back timber 1, base 3, front and back two columns 2 and two linkages 4 etc. of flexible forestope support.Support with forward and backward two root posts 2 between the back timber 1 of flexible forestope support and the base 3, column 2 adopts double-telescopic upright post.Also hinged between the back timber 1 of flexible forestope support and the base 3 by two linkages, the stability of increase support.Back timber 1, base 3 steel plate processing and fabricating.
The mid portion of flexible forestope support by be connected in two crossbeams 12 between the left and right back timber 1 of this support, be vertically fixed in three longerons 11 on the crossbeam 12, in the longeron 11 setting-ins extensible canopy 10 and be articulated in extensible canopy 10 and crossbeam 12 between flexible jack 14 etc. form.
Two crossbeams 12 are processed by channel-section steel.Three longerons 11 are also by channel-section steel processing, and the groove of three longerons 11 upwards is vertically fixed on two crossbeams 12.Three extensible canopies 10 are by the channel-section steel processing littler than longeron 11 cross sections, the groove of extensible canopy 10 downwards, be inlaid in the groove of longeron 11.The cylinder body end of flexible jack 14 is articulated on the hinged seat of crossbeam 12 bottom sides, the piston rod of flexible jack 14 and the hinged seat of extensible canopy 10 front end bottom sides are hinged, it is flexible that extensible canopy 10 longitudinally can be free to slide in the groove of longeron 11, reaches the purpose of front-probe support.
2. pass and anti-down jack: the two is in the left and right sides of flexible forestope support, that is takes a step each side there is one from moving supporting bracket, and bilateral symmetry.
Passing jack 5 two ends of each side connect with the base 6 of taking a step from moving supporting bracket with the base 3 of flexible forestope support respectively by fixed connector.Anti-down jack 9 two ends of each side connect with the back timber 8 of taking a step from moving supporting bracket with the back timber 1 of flexible forestope support respectively by rotatable connector.The fully-mechanized mining working that passing and anti-down jack use stroke to reach 900mm draws back slide jack.
3. take a step from moving the supporting bracket part: form by the left and right sides and intermediate portion that structure is identical.Each side is made of back timber 8, column 7 and the base 6 etc. of taking a step from moving supporting bracket.The intermediate portion is to be connected in the crossbeam 13 of taking a step between the left and right back timber 8 that moves supporting bracket; Take a step to have the anti-effect of skewing, process with channel-section steel from the crossbeam 13 that moves supporting bracket.Back timber 8 is short beams, mainly plays connection column 7, crossbeam 13, anti-down jack 9 connectors except playing a supportive role.Take a step to adopt double-telescopic upright post from the column 7 that moves supporting bracket; Its back timber 8 and base 6 adopt the steel plate processing and fabricating.
Fully mechanized workface shown in Figure 4 is taken a step from the hydraulic system of moving cantilever timbering.It is made up of each column of operation valve group 15, this cantilever timbering and hydraulic jack, high-pressure rubber pipe etc.Operation valve group 15 contains five 3-position 4-way operation valves.The liquid inlet and outlet of five operation valves is connected with feed flow pipeline P, the liquid back pipe road O of hydraulic power unit respectively; The working hole of five operation valves passes through high-pressure rubber pipe, respectively with the anti-down jack 9 of the passing jack 5 of the flexible jack 14 of the column 2 of the flexible forestope support of four parallel connections, three parallel connections, two parallel connections, two parallel connections, two parallel connections take a step be connected from the column 7 that moves supporting bracket, constitute five road hydraulic circuits.Wherein, the rodless cavity of four columns 2, two columns 7 also is connected to control valve 16.Control valve 16 contains unidirectional lock and safety valve.For the hydraulic power unit of this cantilever timbering feed flow is located in the tunnel, by feed flow pipeline P and liquid back pipe road O be arranged on the operation valve group 15 of taking a step and be connected from moving on the supporting bracket.
Using method:
1. in the intact circulation of fully-mechanized digging machine cut, this support at first rises roof supporting with this support after reaching boring head;
2. handle support operation valve group 15 corresponding operation valves,, three extensible canopies 10 are stretched out, play the effect of support front top board flexible jack 14 feed flows;
3. carry out the supporting such as anchor pole, anchor net, anchor cable of boring head top board;
4. after next one circulation driving finishes, move back fully-mechanized digging machine;
5. handle corresponding operation valve, fall the back timber 1 of flexible forestope holder part, take a step from move supporting bracket part roof supporting firmly after, stretch and pass jack 5 and anti-down jack 9, pass flexible forestope holder part;
6. after flexible forestope holder part puts in place, handle corresponding operation valve, rise back timber 1 roof supporting; After the firm supporting, take a step partly to fall back timber 8, contract and pass jack 5 and anti-down jack 9, draw and take a step from moving the supporting bracket part from moving supporting bracket;
7. take a step after moving supporting bracket and partly putting in place, the manipulation operations valve, it is firm to rise back timber 8 roof supportings;
8. according to 1. above-mentioned～3. the step supports to place this support and forestope thereof, and the roofbolt of meeting head on, anchor net, cable bolting; Again by 4. above-mentioned～7. the step finishes this support to move frame; And circulation according to this.
This fully mechanized workface takes a step to be with flexible forestope from moving the cantilever timbering supporting height at 1.6 meters～3.5 meters, and temporary lining length can reach 3.9 meters, 4 meters of overall widths, and 3.4 meters of inner widths cooperate fully-mechanized digging machine to use.Use at No. two collieries, Yanzhou Coal Industry Co., Ltd. Jining fully mechanized workface, obtained good effect.
