At present in the world in the middle of shield mainstream model, the kind of design of centre revolving joint mainly has two types: As shown in figure 4, driving central partition plate to serve as a part for native storehouse dividing plate wherein based on left figure, it is fixed structure, center steering connects Head passes through this dividing plate, realizes sediment improvement agent and the conveying of hydraulic oil with cutterhead pipeline support after being connected;Main driving nothing in right figure Central partition plate, cutterhead flange is solid construction, and centre revolving joint is arranged on cutterhead flange center position, sediment improvement pipeline and Fluid pressure line extends to cutter head panel specified location by bracket root.The substantially phase of shield swivel coupling design both at home and abroad at present With using two section designs, one saves the big swivel coupling for trandfer fluid to the overwhelming majority, and a little revolution saving as delivery hydraulic pressure oil connects Header structure, this structural volume is huge, not compact, and swivel coupling positioning accuracy request is higher, center no agitating function and in The heart sprays water with high pressure function, the easy mud lining of cutter head center, costly;Also small part is had to adopt integral structure, but this knot Structure design defect itself, does not adopt the high very high rolling bearing of essence, and center is no stirred and central high pressure spraying function, and center holds Cutterhead mud cake problem easily occurs, costly.
Therefore it provides a kind of centre revolving joint adopts integral design structure, make more compact structure, and can be good at Solve cutter head center easily incrusted problem, and manufacturing cost can be reduced and the new earth pressure shield tunneling machine of maintenance cost returns Adapter, has been a good problem to study.
Content of the invention
In order to overcome above-mentioned deficiency of the prior art, the invention provides a kind of adopt integral design structure, fluid Passage and hydraulic channel, in one, make more compact structure, reduce manufacturing cost and maintenance cost, also solve well simultaneously The native shield machine centre revolving joint of the easily incrusted problem of cutter head center.
The object of the present invention is achieved like this:
A kind of balancing earth-pressure shielding machine centre revolving joint, including central stator 1, central stator 1 passes through bearing with rotor 4 Connect;Central stator 1 is coupled by spline respectively with passive stirring rod 9 and block 11;Central stator 1 afterbody is provided with water connector Device 10, rotor 4 is connected by bearing with periphery stator 5, and the cutterhead flange that rotor 4 is directly fixedly connected with cutterhead couples;
Described includes sliding bearing 2 and self-aligning roller bearing 6 for connecting central stator 1 and rotor 4 bearing;
It is provided with spout 13 in described passive stirring rod 9;
Described central stator 1 end directly couples fluid pressure line 12, is transported in cutterhead by rotor 2;
Described periphery stator 5 directly couples fluid medium delivery pipe 7, is transported in cutterhead by rotor 2;
The outer ring of described rotor 4 is coupled with periphery stator 5 by spring bearing 8;Pass through between rotor 4 and fluid circuit Lip packing 3 seals each fluid circuit.
Positive beneficial effect: the present invention adopts integral design structure, fluid passage and hydraulic channel, in one, make structure More compact, have stronger can processing type, reduce manufacturing cost and maintenance cost;The present invention is set using bimorph transducer, single rotor Meter, fluid media (medium), hydraulic medium easily convey, and rotation support adopts bearing, high precision, Center stirring and central high pressure to wash away System, solves the problems, such as cutter head center mud lining, and saves ep2 grease 0.24l/ ring, hbw0.5l/ ring.
