Abstract
A high-strength terminal anchor line clamp for a contact line and a carrier cable comprises a line clamp body (1) and a tapered wedge (2). The line clamp body (1) is integrally formed by adopting the precision die forging process to ensure that the upper part of the line clamp body (1) is double sleeve lugs (4); the lower part of the line clamp body (1) is a tapered column body (5); a rectangular window (6) is arranged on a sleeve (8) at the lower part of the double sleeve lugs (4); a tapered hole (7) is formed in the center of the tapered column body (5); and the tapered wedge (2) is inserted in the tapered hole (7). Compared with the prior art, as the line clamp body is integrally formed by adopting the precision die forging process, the production quality and the safety quality of products can be guaranteed, the manufacture efficiency is improved, the integral strained condition of the wire clamp can be best, and the mounting and the use are convenient. The high-strength terminal anchor line clamp can meet the use requirements of high-tension and heavy-loaded lines.
Description
Technical field
The utility model belongs to contact nets in electrified railways Parts manufacturing technology field, is specifically related to a kind of contact wire and catenary high strength terminal anchoring clamp.
Background technology
With the immediate prior art of the utility model be utility model patent " novel terminal-anchoring wire clamp for contact wires " (CN200920032816.7), constitute by ears bolt, sleeve, cover of wedge and chock; The ears bolt is connected with bush whorl, and cover of wedge is positioned at sleeve, and chock is inserted in the cover of wedge, passes through cone match between the two.Main guarantee because this wire clamp is stressed, under extreme case, be prone to generation running phenomenon, and cover of wedge and sleeve be separate type, cause the wire clamp overall construction intensity lower, be not suitable for the clue operating needs of high speed railway hightension, heavy lift through threaded engagement.
The utility model content
The technical matters that the utility model solves: design a kind of contact wire and catenary high strength terminal anchoring clamp; Its wire clip body adopts the precision die forging process global formation; The quality of production and the safe mass of product have been guaranteed; Improve manufacturing efficient simultaneously, and made the whole strained condition of wire clamp reach best, be applicable to the clue operating needs of high speed railway hightension, heavy lift.
The technical scheme that the utility model adopts: a kind of contact wire and termination fitting for catenary comprise wire clip body and taper chock.Said wire clip body adopts the precision die forging process global formation; Make the top of wire clip body be shaped to the sleeve ears, the bottom is shaped to the taper cylinder, and has rectangular window on the sleeve of sleeve ears bottom; The central authorities of taper cylinder are shaped on taper hole, and the taper chock is inserted in the taper hole.
Have two symmetrical rectangular windows on the sleeve of said sleeve ears bottom, the ears on said sleeve ears top are " U " type ears, and rectangular window is positioned at the below of " U " type ears.
Said wire clip body adopts Cu alloy material to process.
Be fitted with pin on the connecting bore of said " U " type ears upper end.
The utility model compared with prior art wire clip body adopts the precision die forging process global formation, has guaranteed the quality of production and the safe mass of product, has improved manufacturing efficient simultaneously, and makes the whole strained condition of wire clamp reach best, and easy to install.Be applicable to the clue operating needs of high speed railway hightension, heavy lift.
