Utility model content
The cable line existed for solving prior art arranges irrational technical matters, and the utility model provides that a kind of structure is simple, cable favorably situated lorry-mounted crane integral type swivel coupling.
For achieving the above object, the technical scheme that the utility model adopts is a kind of lorry-mounted crane integral type swivel coupling, comprise: stator body and rotor block, described rotor block is sleeved on the outside of stator body, the lower circumference of described stator body is provided with flange, the top of described stator body is provided with the back-up ring for locating rotor block, the center of described stator body is provided with cable through hole, the top of described cable through hole is fixed with permanent seat, and the end of described stator body is also provided with O RunddichtringO.
Preferably, described stator body be circumferentially provided with multiple annular oil groove, multiple the first oil circuit be connected with annular oil groove is also provided with in stator body, multiple second oil circuit is provided with in described rotor block, described second oil circuit is corresponding with annular oil groove, and the both sides up and down of annular oil groove are provided with seal ring.
Preferably, the upper surface of described rotor block is fixed with baffle plate.
Compared with prior art, the utility model has following technique effect: the utility model structure is simple, easy to use, safe and reliable, installing/dismounting is convenient, adopt cable along stator body center arrangement, top is by rotating connectors junction circuit, cable arrangements is reasonable, not easy fracture; Stator body and rotor block all adopt one-piece construction simultaneously, decrease welding sequence, improve bulk strength and the withstand voltage properties of swivel coupling, greatly reduce the risk of leakage of swivel coupling; O shape circle is installed in stator body end, the both sides up and down of annular oil groove are provided with seal ring, adopt double-layer seal, can prevent dust and dirt from falling into swivel coupling internal galleries, avoid swivel coupling sealing member to damage, improve reliability and the service life of swivel coupling work.
