Chain rail shield 22 safety that can completely protect fuselage the same as the shield shell of prior art shield machine, not by the impact that hole wall caves in, but the shield shell of prior art shield machine is rigidity, movement, it is shield machine advance resistance that hole wall and shield shell joint touch friction, hole wall is coarse or have the outstanding stone be scattered, shield machine shell will be stuck and can not advance, pending fault will be there is, and the chain rail shield of numerical control full-automatic full-section rock shield machine of the present invention is that relative flexibility is treated, roll, the friction of hole wall and shield plate is the support force advanced, coarse or the outstanding stone that is scattered of hole wall does not affect the machine and advances, can smoothly by not breaking down.Support piston bar 31 and cabin shell 27 are fastenedly connected, when support cylinder 29 large chamber charged pressure oil, supporting bridge 28 can make track (shoe) 9 be adjacent to hole wall, thus the moment of torsion of thrust needed for generation the machine and anti-cutter disc torque, track (shoe) 9 is close to hole wall, most of hole wall is close to supporting, remaining small part space is by the inner casing 23 installed on supporting bridge, outer casing 24, middle backplate 25 and apron plate 4 supporting, these backplates are not be close to hole wall, only block falling rocks slag, and this just reaches the comprehensive supporting of complete machine.
Track (shoe) 9 is driven by drive axle 47, by hydraulic motor 43, via worm screw 38 to worm gear 37, worm screw 39, worm gear 40, pinion 41, gear wheel 42, driving wheel 8 is to track (shoe) 9. because the speed of driving is very little when working, the speed of driving wheel 8 is very low, so adopt two-stage worm gear reducer, hydraulic motor 43 power can be very little, and driving wheel can produce large thrust, reach the thrust of cutterhead 2, but movement during inoperative, this speed is just too little, lose time very much, thus pinion 44 is designed with, gear wheel 45 and clutch 46, when clutch 46 to gear wheel 45 side in conjunction with time just realize more than 2,000 times quick, the machine realizes when off working state is movably walking the machine fast.
Cutterhead 2 works and produces moment, be close to hole wall by track (shoe) 9 and produce opposing torque balance, now track (shoe) 9 is stressed again after being first adjacent to, obvious displacement can not be produced, but the time has been grown and can produce drift, although this drift is very little, cabin can be made with the passage of time to turn to cutterhead and to change into the end in the opposite direction towards sky.Thus deflection guide frame is devised, the guide ring 35 that an axle around cabin 27 rotates, guide ring 35 is equipped with guide support piston rod 34, with guiding oil cylinder 33 and guide bridge 21, track (shoe) 9 is made only not to be close to hole wall close to hole wall after the large chamber of guide support oil cylinder 33 is oil-filled, therefore when cutter works clockwise, and it is oil-filled to deflect oil cylinder 36 clockwise, guide bridge 21 is dialled directive wheel 5 and is partial to clockwise laying with the track (shoe) 9 not being adjacent to hole wall, thus cabin is deflected partially clockwise, to keep balance, when cutter works and counterclockwise partially oil cylinder 32 is oil-filled counterclockwise, cabin is made to turn counterclockwise to keep balance with comprehending.This process automatically controls.
Accompanying drawing 6 is cutterhead 2 schematic diagrames of numerical control full-automatic full-section rock shield machine of the present invention, cutterhead 2 adopts and spoke structure, be made up of wheel hub, spoke and wheel rim, the radius of spoke and wheel rim accounts for 1/10 of cutter radius, leaves the space of the space between spoke as look ahead cutterhead prior fault.
The contact strength of rock is more weak, according to the contact maximum stress of theory of elastic mechanics spheroid and plane
be:
-----------------------------------1
In formula: P is pressure, E is modulus of elasticity,
