Embodiment Construction

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

[0055] The structure of the anti-positioning integral wrist arm of the present invention, as figure 1 , 2, 3, 4 shown. Including the horizontal arm 1, the right end of the horizontal arm 1 is curved into an arc, the radius of the arc in the center of the arc is 1000mm, and the right end of the arc is welded with an oval end plate and a U-shaped double ear connecting plate. U-shaped double ears 1-3, a pair of connecting plates on the U-shaped double ears 1-3 are arranged symmetrically with respect to the central axis of the cylindrical channel of the horizontal wrist arm, and constitute the overall U-shaped double ears 1-3, U-shaped The two ears 1-3 are located on one side of the front of the horizontal wrist arm and have a square through hole. The circular through-holes are arranged coaxially, and the square through-holes of the U-shaped e...

Abstract

The invention discloses a reversely-positioning integral cantilever of an electrified railway contact network comprising a horizontal cantilever. One end of the horizontal cantilever is thermally bent into an arc shape; U-shaped double lugs are welded at the end part of the arc; a double-hole connecting plate is fixedly connected with the lower surface of the end part; a force-bearing cable seat is fixedly connected with the upper surface of the end part; the double-hole connecting plate is connected with one end of an inclined cantilever; the inclined cantilever and the horizontal cantileverare arranged along the same direction to form an included angle; a hinge type positioning ring is fixedly connected with the inclined cantilever; the positioning ring is connected with one end of a horizontal positioning pipe; the other end of the horizontal positioning pipe is connected with the horizontal cantilever; a positioner supporting seat is fixedly connected with the horizontal positioning pipe and is fixedly connected with one end of an elastic limiting positioner; and a positioning wire clamp is fixedly connected with the other end of the elastic limiting positioner. The reversely-positioning integral cantilever is used at a reversely-positioning part of the electrified railway catenary so as to fixedly support a contact wire and a force-bearing rope, stabilize the contact network and prevent the off-line 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 reverse positioning integrated 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. ...
