Double-centre swinging single-bow current-collector

Abstract

The invention discloses a double-centre swinging single-bow current-collector, which comprises a base and an inclined frame, wherein the lower end of the inclined frame is arranged on the base by a rotary pin shaft, and the upper end of the inclined frame is connected with the middle part of a vertical rack by a rotary shaft; the middle part of the top end of the base is connected with the bottom end of an inclined supporting rod by a middle rotary pin shaft; the top end of the inclined supporting rod is hinged with the middle part of the upper end of the vertical rack; a transverse rod is arranged at the middle part of the inclined frame; the left side of the transverse rod is connected with the top end of a left inclined tension spring; the bottom end of the left inclined tension spring is connected with the top end of a right connecting rod; the lower part of the left connecting rod is rotatably fixed on the left side of the top part of the base; the right side of the transverse rod is connected with the top end of a right inclined tension spring; the bottom end of the right inclined tension spring is connected with the top end of a right connecting rod; and the lower part of the right connecting rod is rotatably fixed on the right side of the top part of the base. The invention aims to provide the double-centre swinging single-bow current-collector, which is always in the state of forwardly operating along an overhead wire, is stable in working performance, long in service life, convenient in operation, maintenance and replacement, and can adapt to complicated and rough landforms.

Description

technical field [0001] The invention relates to a double-center swing single-bow receiver. Background technique [0002] The receivers used by electric locomotives are divided into two types: single-bow and double-bow, and the single-bow receiver is more suitable for adapting to complex and harsh landforms. The operation characteristic of the double-bow receiver is that when the electric locomotive moves forward and backward, it drags the bow and runs along the wire, but the driver needs to operate and change the receiver in time according to the change of the running direction of the electric locomotive, which brings great inconvenience to the driver's operation. It is a big inconvenience, and the double-bow receiver needs to work under better road conditions. Single-bow receivers usually require the driver to control the operating rope to lift and lower the receiver. The operating characteristics of single-bow receivers are that if the electric locomotive is dragging the ...

Problems solved by technology

The operation characteristic of the double-bow receiver is that when the electric locomotive moves forward and backward, it drags the bow and runs along the wire, but the driver needs to operate and change the receiver in time according to the change of the running direction of the electric locomotive, which brings great inconvenience to the driver's operation. Big inconvenience, and the double-bow receiver needs to work under better road conditions

Single-bow receivers usually require the driver to control the operating rope to lift and lower the receiver. The operating characteristics of single-bow receivers are that if the electric locomotive is dragging the bow in the forward direction and running along the wire, then when it is facing backward, the bow can only be reversed. The disadvantage of reverse overhead wire operation is that when passing through complex and bad roads or passing through overhead line forks, it is very easy to cause the receiver to touch the body or penetrate into the crossing point of the fork, causing the receiver to bow. Damaged, or hanging broken overhead lines
