Among the figure: 1-back timber, 2-column, 3-base, 4-two linkages, 5-advancing 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-operating valve group, 16-control valve.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
The structure of stepping self-moving type cantilever timbering on integrated drilling working surface of the present invention is shown in Fig. 1~3.It mainly by flexible front canopy support, passing and anti-down jack, take a step to form from moving the supporting bracket three parts.
1. flexible front canopy support part: the left and right sides and the intermediate portion identical by structure form; Each side is made of back timber 1, base 3, front and back two columns 2 and two linkages 4 etc. of flexible front canopy support.Support with forward and backward two root posts 2 between the back timber 1 of flexible front canopy support and the base 3, column 2 adopts double-telescopic upright post.Also hinged by two linkages between the back timber 1 of flexible front canopy support and the base 3, the stability of increase support.Back timber 1, base 3 steel plate processing and fabricating.
The mid portion of flexible front canopy 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, the extensible canopy 10 of longeron 11 interior setting-ins 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 less 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 front canopy support, that is takes a step each side there is one from moving supporting bracket, and bilateral symmetry.
Advancing 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 front canopy 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 front canopy support respectively by rotatable connector.The fully-mechanized mining working that passing and anti-down jack use stroke to reach 900mm draws rear slide jack.
3. take a step from moving the supporting bracket part: the left and right sides and the intermediate portion identical by structure form.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 from the crossbeam 13 that moves supporting bracket, process with channel-section steel.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.
The hydraulic system of stepping self-moving type cantilever timbering on integrated drilling working surface shown in Figure 4.It is comprised of each column of operating valve group 15, this cantilever timbering and hydraulic jack, high-pressure rubber pipe etc.Operating valve group 15 contains five 3-position 4-way operating valves.The liquid inlet and outlet of five operating valves is connected with liquid feeding pipeline P, the liquid back pipe road 0 of hydraulic power unit respectively; The working hole of five operating valves passes through high-pressure rubber pipe, respectively with the column 2 of the flexible front canopy support of four parallel connections, the flexible jack 14 of three parallel connections, the advancing jack 5 of two parallel connections, the anti-down jack 9 of two parallel connections, two parallel connections take a step be connected from the column 7 that moves supporting bracket, consist of 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 one-way lock and safety valve.For the hydraulic power unit of this cantilever timbering feed flow is located in the tunnel, by liquid feeding pipeline P and liquid back pipe road O be arranged on the operating valve group 15 of taking a step from moving on the supporting bracket and be connected.
Using method:
1. in the complete circulation of fully-mechanized digging machine cut, this support at first rises roof supporting with this support after reaching boring head;
2. handle support operating valve group 15 corresponding operating valves, to flexible jack 14 feed flows, three extensible canopies 10 are stretched out, play the effect of support front top board;
3. carry out the supporting such as anchor pole, anchor net, anchor cable of boring head top board;
4. after next one circulation driving is complete, move back fully-mechanized digging machine;
5. handle corresponding operating valve, fall the back timber 1 of flexible front canopy support part, take a step from move supporting bracket part roof supporting firmly after, stretch advancing jack 5 and anti-down jack 9, pass flexible front canopy support part;
6. after flexible front canopy support partly puts in place, handle corresponding operating valve, rise back timber 1 roof supporting; After the firm supporting, take a step partly to fall back timber 8 from moving supporting bracket, contracting advancing jack 5 and anti-down jack 9 draw and take a step from moving the supporting bracket part;
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 according to this circulation.
This stepping self-moving type cantilever timbering on integrated drilling working surface supporting height is with flexible forestope 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.No. two excavation face in coal mines use in Yanzhou Coal Industry Co., Ltd. Jining, have obtained good effect.
