Abstract

The invention belongs to a current carrying type adjustable integral dropper used when a contact system in an electrified railway suspends a contact wire on a catenary wire, which is characterized inthat a catenary wire dropper cable clamp (1) adopts a primary and secondary leaf hinge structure and can rotate around a rotation axis, and a set of adjusting bolts is used for fastening the lengths of the catenary wire (17) and an adjusting dropper wire (4). The current carrying type adjustable integral dropper saves constructing maintenance time and can be used easily, has a high strength of a wire clamp body and a high ability of anti-plastic deformation, and overcomes the phenomenon of easy looseness resulted from diameter shortening because of the integration when the secant and the groove of the adjusting bolt are fastened.

Description

technical field [0001] The invention belongs to a device used when an electrified railway catenary is suspended on a catenary cable, in particular to a current-carrying adjustable body suspension string. Background technique [0002] At present, the hanging string clips used to fasten the catenary cables on the upper part of the catenary parts of electrified railways in my country have a two-piece symmetrical structure. Tighten the catenary cable, and adjust the length of the suspension string by loosening and tightening another set of adjustment bolts to adapt to the change in the height of the structure at the installation place. The overall suspension string of this structure clamps the catenary cable and adjusts The length of the hanging string is completed by fastening two sets of bolts, which brings trouble to the construction, prolongs the construction time, and does not meet the tight requirements of the busy railway trunk line construction and maintenance time. The o...
