Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The present invention is positioning the structure of the integral wrist arm, such as figure 1 shown. It includes a horizontal arm 1, one end of the horizontal arm 1 is sealed, and the other end is a free end. A rotatable and adjustable catenary cable seat 4 is fixed near the sealing end, and the catenary cable seat 4 is used to support the catenary cable. Bolt holes C 1-7 are set near the free end of the horizontal wrist arm 1. Through the bolt hole C 1-7 and bolt assemblies are connected with rod insulators. A double-hole connecting plate 1-4 is arranged at the bottom near the sealing end of the horizontal arm 1, and is connected with one end of the oblique arm 2 through the double-hole connecting plate 1-4, and the other end of the oblique arm 2 is a free end. The free end of the wrist arm 2 is set in the same direction as the fr...

Abstract

The invention discloses a pull-off mode integral type cantilever of overhead contact line equipment of an electrified railway, which comprises a horizontal cantilever, wherein at least two through holes are processed on one end of the horizontal cantilever side by side; the lower surface of the end of the horizontal cantilever is fixedly connected with a double-hole connecting plate; the upper surface of the end of the horizontal cantilever is fixedly connected with a catenary wire base; the double-hole connecting plate is connected with one end of an inclined cantilever; the inclined cantilever and the horizontal cantilever are arranged in the same direction; an included angle is formed between the inclined cantilever and the horizontal cantilever; the inclined cantilever is fixedly connected with two hinge-type positioning rings respectively; the positioning rings are connected with two ends of a horizontal positioning pipe respectively; 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 pull-off mode integral type cantilever is used at a pull-off mode position of the overhead contact line equipment of the electrified railway and isused for fixedly supporting a contact wire and a catenary wire, stabilizing the overhead contact line equipment and avoiding offline accidents.

Description

technical field [0001] The invention belongs to the technical field of electrified railway catenary, and relates to a wrist arm positioning device, in particular to a positive positioning integral 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 a positive positioning wrist arm device and a reverse positioning wrist arm device. The positive positioning wrist arm device is used to support contact suspensions such as catenary cables and contact lines at the positive positioning position, and to transfer lo...
