The specific embodiment
A kind of pair of cantilever hard rock coal road pick anchor equipment, referring to Fig. 1-Fig. 3, include coal conveyer, hydraulic system, electrical control system, dust pelletizing system, dynamical system, headstock, be connected in the cantilever cutter sweep of headstock front end, the crawler unit 14 of headstock below and the supporting platform 10 that is articulated in the headstock rear end, be provided with temporary support device in the headstock upper end, be provided with roofbolt rig 6 and side wall jumbolter 9 at described supporting platform, also be provided with net sheet travelling bogie 7 on the supporting platform.
Cutting means is made of 2 pairs of cutterheads 1 of two cantilevers, two cantilever cutterheads distribute along center line, 1 parallel motion of two cutterheads, cutting half of rock (coal) layer separately respectively, they both can be synchronized with the movement, again independently moving separately, setting by control program, two cutterheads, 1 interference can not occur, cutting has improved whole driving speed simultaneously.Temporary support device includes the supporting leg 4 that four hoist cylinders that are fixed on the headstock consist of, be connected in double-deck interim ceiling 3 and the finger-type shield 5 that is connected in the temporary support device rear end on the supporting leg 4, the strip structure that described finger-type shield 5 is welded for plurality of steel plates, temporary support device is in tunneling process, can adjust the length that double-deck interim ceiling 3 stretches out according to the stroke of cantilever 2, shorten as much as possible unsupported back span, the oil cylinder on the protection cantilever 2; Interim ceiling 3 be double-decker, and the net sheet for supporting can be stored in interlayer inside, simultaneously temporarily ceiling 3 also for the protection of operating personnel and the dynamical system of headstock inside; In the linked network operating process, finger-type shield 5 is used for holding the net sheet that exposes, simultaneously the constructor under the protective mooring rod rig; Four hoist cylinder supporting legs 4 can make the double-deck interim certain distance of ceiling 3 liftings, avoid because the reach difficulty that the out-of-shape of excavation face causes.
But relative sliding between supporting platform 10 and the headstock, simultaneously, supporting platform 10 can swing certain angle along headstock in vertical plane, is used for compensation ground, tunnel out-of-flatness and causes supporting platform 10 to tilt.The movement of supporting platform 10 is by the oil cylinder pushing on the sidewall support boots 13, side wall support boots 13 can slide along supporting platform 10, the roofbolt rig 6 of distribution varying number and side wall jumbolter 9 on the supporting platform 10, rig quantity can be according to the demand coupling of driving speed.Supporting platform 10 is cavity, the inner drag conveyor 11 of placing.Liftable net sheet travelling bogie 7 both can be used as vehicle, and the net sheet is carried forward from the equipment rear portion, can be used as again the lifting appliance that the net sheet is installed, and the net sheet is risen certain altitude, and the convenient operation personnel place the net sheet in the cavity of temporary support device.
The new-type dust removal with machine of rotation brattice purifies equipment, adopt development machine spray dust-reducing system and rotation brattice to take out the combination of dirt cleaning system, utilize the rotary airflow generator to produce swirling eddy, form the rotation brattice with spiral air flow the dust that fully mechanized workface produces is locked in the place ahead, driver position, by deduster work plane can all not collected by all dust of spraying sedimentation, then be that it is purged again.Smoke the dirt purification and realize by wet scrubber, the air of dust-laden is sucked into deduster, by the water curtain of special nozzle generation, dust and water are mixed, pass the demist bed course, do further mixing, then pass through drop separator dust (sewage) is separated with air.The two cooperates to make development machine spray dust-reducing system and rotation brattice take out the dirt cleaning system, reaches the effect of high-effective dust-removing.
Cutterhead 1 stretches out the distance of 500mm during work along cantilever 2, cantilever about 2 swings up and down, cut whole section rock (coal) layer, owing to being the two cutterhead structures of two cantilevers, two cantilevers 2 can be set in control program can be synchronously or carry out alone the cut operation, and mutually noninterfere between two cantilever 2 operational periods; The earth-moving equipment 15 of bottom is sent into drag conveyor 11 to fallen rock (coal) material by starry wheel, and rock (coal) material is transported to the rear portion; After cantilever 2 reaches range (500mm), the headstock 500mm that under crawler unit 14 drives, moves forward, cutterhead 1 continues cutting rock (coal) layer; When carrying out tunneling process, jumbolter on the supporting platform matches with temporary support device on the headstock and implements the anchoring operation, in tunneling process, temporary support device scalable temporary supporting plate stretch out forward along with the elongation of cantilever, oil cylinder on the protection cantilever 2, the net sheet of storage also stretches out along with the driving progress in the double-deck interim ceiling 3, rests on the finger-type shield 5, is anchored on the top board by roofbolt rig 6 again; During this time net sheet transportation installation carriage 7 comes the transport network sheet as required, or assists the net sheet in interim ceiling 3 interior storage and the installations of bilayer; Side wall jumbolter 9 on the supporting platform 10 carries out the anchoring operation of sidewall simultaneously, and all jumbolters can carry out the anchoring operation neatly in certain distance and angle.Crawler belt moves forward the distance of 1m, and after the anchoring operation comes to an end, side wall support boots 13 stretching sidewalls, rear support boots 12 are regained, and propelling cylinder is pushed ahead 1m with supporting platform 10, then puts down supporting platform rear support boots, unclamp side wall support boots 13, reclaim propelling cylinder.Reciprocating working realizes that excavation operation and anchoring operation are in overall temporal coupling successively.
