Push-off mode adjustable cantilever of overhead contact line equipment of electrified railway

Abstract

The invention relates to a push-off mode adjustable cantilever of overhead contact line equipment of an electrified railway, which comprises a horizontal cantilever, wherein six through holes are formed on the horizontal cantilever side by side; a catenary wire base is fixedly connected to the horizontal cantilever; the right end is bended into an arc shape; five through holes are formed on an arc section and are used for fixedly connecting an adjusting device; the horizontal cantilever is fixedly connected with two positioning rings, one of the positioning rings is connected with one end of an inclined cantilever, the inclined cantilever and the horizontal cantilever are arranged in the same direction to form an included angle, and the other positioning ring is connected with one end of a cantilever support; and the inclined cantilever is fixedly connected with two positioning rings, one of the positioning rings is connected with one end of a horizontal positioning pipe, the other end of the horizontal positioning pipe is connected with the adjusting device, the horizontal positioning pipe is fixedly connected with a positioner supporting base, the positioner supporting base is fixedly connected with one end of an elastic limiting positioner, and the other end of the elastic limiting positioner is fixedly connected with a positioning cable clamp. The push-off mode adjustable cantilever is used at a push-off mode position of the overhead contact line equipment of the electrified railway and is used for fixedly supporting a contact wire and a catenary wire, stabilizing the overhead contact line equipment, and preventing offline accidents.

Description

technical field [0001] The invention belongs to the technical field of electrified railway catenary, relates to a wrist arm positioning device, in particular to a reverse positioning adjustable wrist arm of electrified railway catenary. Background technique [0002] In the wrist-arm structure of the electrified railway catenary system, the contact wire and catenary wire sag under the action of its own weight, resulting in the unsteady contact of the pantograph and affecting the current flow. Therefore, the wrist-arm positioning device is used to support the contact wire and catenary cable Keep it in a horizontal state to ensure that the locomotive receives current. The wrist-arm positioning device is divided into positive positioning wrist-arm device and reverse positioning wrist-arm device, wherein the reverse positioning wrist-arm device is used to support contact suspensions such as catenary cables and contact lines at the reverse positioning, and to transfer loads.
