With the rapid development in city, skyscraper is more and more, and building power load sharply increases therewith, original
Electric wire because its capacity is small, branch is inconvenient, is not easy to the reasons such as boundling management, progressively by capacity is big, branch and
The convenient bus duct substitution of boundling management.Bus expansion joint is to be added for compensation bus duct caused by temperature difference and mechanical oscillation
Stress, and it is arranged on a kind of flexible structure on bus duct.Because it is as a kind of elastic compensation element that can freely stretch, tool
There is reliable operation, functional, compact-sized, existing generatrix groove expansion joint is all only capable of cold to bus duct thermal expansion mostly
The compensation of axial displacement is carried out during contracting can not carry out the compensation of radial displacement.
Utility model content
The purpose of this utility model is：A kind of generatrix groove expansion joint is provided, axial displacement and radial displacement can be carried out
Compensation, to extend the service life of bus duct, improves its security.
The technical solution adopted in the utility model is as follows：
A kind of generatrix groove expansion joint, including two sections of busbar bodies and every wire, it is characterised in that two sections of bus masters
First sleeve and the second sleeve pipe are arranged with body, the first fixed plate and the mother in first sleeve are provided with the first sleeve
The first radially movable plate at line main body top, the described one end of first fixed plate away from first sleeve are arranged with outside axially activity
Plate, outside axial direction portable plate close to the first radially movable plate and away from first sleeve side be provided with first radially it is spacing
Plate；Second that busbar body top in the second fixed plate and close second sleeve pipe is provided with second sleeve pipe is radially movable
Plate, the described one end of second fixed plate away from the second sleeve pipe are close to the axial portable plate inner sleeve in outside and are provided with inner side axially activity
Plate, inner side axial direction portable plate close to the second radially movable plate and away from the second sleeve pipe side be provided with second radially it is spacing
Plate.
The one end of outside axial direction portable plate away from the first fixed plate at the contact surface of inner side axial direction portable plate with setting
There is sealing ring.
Every wire in two sections of busbar bodies is attached using being flexible coupling.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. radial displacement that can be to bus duct rising-heat contracting-cold by the first radially movable plate and the second radially movable plate is carried out
Compensation, can be compensated by outside axial direction portable plate and inner side axial direction portable plate to the axial displacement of bus duct rising-heat contracting-cold,
The service life of bus duct can be extended, improve the security of bus duct.
2. being sealed between the axial portable plate in outside and inner side axial direction portable plate using sealing ring, meet bus duct water proof and dust proof
It is required that.
Brief description of the drawings
