The fix screw complete removal of catenary hanger ear must be overlapped catenary with wire clamp and then connected U type link when C type and D type structural entity dropper are installed at the scene, last tightening screw is held catenary tightly.
Number of patent application shown in Figure 5 is the structure that the catenary hanger ear changes hinge-type in 200820030195.4 the E type dropper, by two semicircles and the adjustable bolt that forms on the hinge, when holding catenary tightly, compress the dropper line, and can adjust the length of dropper line according to the distance between catenary and the contact wire.The hinge of this structure is difficult in processing and manufacturing.
Summary of the invention
The purpose of this utility model provides a kind of catenary hanger ear of easy to use, rational in infrastructure, service-strong current-carrying dropper device.
The purpose of this utility model is to realize like this, the catenary hanger ear of current-carrying dropper device, it is characterized in that: catenary hanger ear integral body is the left-right symmetric structure, at least comprise that an end opening makes the left and right sides form the semi-circular line clamping structure, the bolt hole of band " word " is opened in the lower end of opening.
The middle part, upper end that described opening is vertical has guide groove, turnup structure before and after two outsides.
Described catenary hanger ear lower ending opening.
Described opening have two beadings perpendicular to the middle part, upper end.
Described opening size is slightly less than the catenary cable diameter.
Characteristics of the present utility model are:
1, reduced U type link;
2, convenient on-the-spot installation and adjusting;
3, can exchange with the catenary hanger ear of present all dropper devices.
