Detailed description of the invention
The invention will be further described by reference to the accompanying drawings for embodiment below.
As Fig. 1, shown in Fig. 2 or Fig. 3, a kind of drum shearer that can two-wayly creep into of certainly walking, comprise frame assembly 1, running gear 2, Electronic Control Assembly 3, hydraulic pressure assembly 4, electronic cutterhead 5, ventilation installation 6, helicoidal gear 7, propulsion arms device 8, propulsion arms docking push unit 9, frame assembly 1 comprises running gear 2, propulsion arms propulsion plant 20, propulsion arms docking push unit 9, support cylinder 22 and vehicle frame lifting gear 27, running gear 2 comprises hydraulic motor 18 and crawler belt 19, frame assembly 1 is connected with the vehicle frame bracing frame 23 on running gear 2 by the device 24 that is connected and fixed, Electronic Control Assembly 3, hydraulic pressure assembly 4 is connected with frame assembly 1 respectively by bearing pin with armouring disk 21, described electronic cutterhead 5 comprises cylinder 10, crab claw scraper plate 11, scrapper conveyor 12, coal-winning machine motor 13, reducer 14 and conveying worm motor 15, crab claw scraper plate 11, reducer 14 and conveying worm motor 15 have two respectively, be positioned at the both sides of cylinder 10 inside strake machine 12.
Described electronic cutterhead 5 has two, lays respectively at car body both sides.
An electronic cutterhead 5 there are two crab claw scraper plates 11.
Described Electronic Control Assembly 3, hydraulic pressure assembly 4 and armouring disk 21 are provided with respectively by bearing pin and are wheeledly connected with frame assembly 1 from walking arrangement.
Described hydraulic motor 18 and crawler belt 19 are respectively two.
Described propulsion arms device 8 includes more piece propulsion arms, is detachable connection between propulsion arms.
As shown in Figure 4 and Figure 5, the propelling of electronic cutterhead 5 and propulsion arms device 8 and the propulsion arms propulsion plant 20 exited by being arranged on frame assembly 1 complete.Power cable, firedamp sensor signal cable, hydraulic pressure, water lines, gamma ray signal cable etc. are installed in the anti-hose reel assembly pounded respectively, in coal mining process, by hydraulically powered armouring garden dish 21, along with the propelling of propulsion arms device 8, along the groove of propulsion arms device 8 side, automatic deploying and retracting.
Ventilation installation 6 is made up of booster and air duct, and air duct is along the groove of propulsion arms device 8 side, and automatic deploying and retracting, dilutes the concentration of the pernicious gases such as the gas in work plane.
As shown in Fig. 6, Fig. 7 and Fig. 8, propulsion arms device 8 can be connected in sequence by more piece, is detachable connection, is used for electronic cutterhead 5 to push coal seam between two joint propulsion arms devices 8.Often linked by high-alloy steel button between joint and connect, make electronic cutterhead 5 and propulsion arms device 8 keep longitudinal rigid to fix.Therein, there is a double-stranded conveying scraper plate, on the left drag conveyor 25 coal being transported to the left and right sides, tunnel and right drag conveyor 26, the power of every root auger is provided by the water-cooled machine be arranged in electronic cutterhead 5, in coal mining process, propulsion arms device 8 only need be transported on the propulsion arms docking push unit 9 on frame assembly 1 by operating personnel, it just can be put into rail plate by propulsion arms docking push unit 9 voluntarily, complete tunnel exploitation, when withdrawing from electronic cutterhead 5, propulsion arms device 8 unloads from slide rail by propulsion arms docking push unit 9 on frame assembly 1 automatically, propulsion arms device 8 only need unload from propulsion arms docking push unit 9 by operating personnel, stacking place is transported to monorail crane.
When electronic cutterhead 5 cuts coal seam and gos deep into, what propulsion arms docking push unit 9 was cycled to repeat loads successively by propulsion arms device 8, makes electronic cutterhead 5 reach the maximum tunnel degree of depth of its design
.
Electronic cutterhead 5 is modular design, can change fast, and cutting drum diameter has two kinds of selections, is respectively 50cm, 80cm.
The wide 3.2m of cutting drum
Drum driven mode: (265kW) 660/1140/50Hz electric motor
Cut scope: 0.7-1.6m
The cutting speed of cutterhead can carry out control adjustment by the PLC computer being arranged on control room.
Gamma ray detection instrument: the top and the bottom that are arranged on cutterhead module, it can control cutterhead and avoid cut roof and base plate, thus avoids the situation that rock or other foreign material are mixed into clean coal.
Electrical control system: the electric switch of cutting motor is arranged in the cabinet of tunnel equipment, without the need to entering coal body inside.
Coal-winning machine of the present invention adopts the technique of only two-way drilling, main frame is arranged in crossheading, first the hand-operated valve duty of pumping plant hydraulic pump is converted to " location " position before exploitation, by handling banked direction control valves handle, the hydraulic motor 18 of running gear 2 drives crawler belt 19, the coal mining position needed in mobile host to tunnel.Secondly, (according to the concrete geological conditions in ore deposit side behind the coal mining position needed in mobile host to tunnel, 0.2-0.3m coal column is stayed in a general and upper drilling hole), operation hoist cylinder, oblique adjusting oil cylinder, the adjustment height of frame and gradient and the coal seam of adopting basically identical, then operate support cylinder 22 and stretch out the both sides being supported on tunnel, namely such main frame completes directed and fixing, and next step just can carry out the operation of brill coal.
Before coal mining activity, first all extracted by the steel anchor rod of the anchor in limit of mining in coal seam, other facilities such as cleaning protective screening are to the rotation and the propelling that do not affect coal-winning machine.Check the laying state of cable and dust-proof water pipe, the fine status of external spraying in checking, after all are normal, open external spraying in coal-winning machine machine, carry out drilling work.When electronic cutterhead 5 cuts coal seam and is deep into a certain degree, what utilize the propulsion arms docking push unit 9 be arranged on frame assembly 1 to be cycled to repeat loads successively by propulsion arms device 8, as above iterative cycles, constantly propulsion arms device 8 is accessed respectively, until move back brill by contrary order when creeping into desired depth in coal-winning machine both sides.
Move back the operation of brill in contrast.
Initial stage of production, electronic cutterhead 5 tail end extends to the middle position of frame assembly 1, promotes drill bit cut along coal seam by hydraulic means.In the two side portions near drilling head module, arrange that pair of parallel diameter is the two-screw conveyer of 50cm, coal is transported by two-screw conveyer by the coal that drill bit is cut off.On the left drag conveyor 25 that the coal that two-screw conveyer transports directly drops on the crossheading left and right sides and right drag conveyor 26, the drag conveyor of crossheading both sides is connected with the extensible belt conveyor in crossheading, and coal is transported.Realize work plane nobody-is-safe exploitation that is thin and ultra-thin coal seam.
