Railway overhead line system bird repellent fixing equipment for preventing rotation or dissociation

Abstract

The invention provides railway overhead line system bird repellent fixing equipment for preventing rotation or dissociation. The equipment comprises a base, wherein limiting blocks are arranged on theouter sides of rotating shafts and are positioned on sides close to bolts in a rotational sleeving manner; vertical grooves corresponding to the limiting blocks are formed in the outer sides of the bolts; rotating rings are rotationally connected with the outer sides of four limiting blocks of each group in the base; driving plates extending to the left sides of limiting blocks on left sides aremoveably connected with the left sides of the rotating rings in the base in an insertion manner; and driven plates corresponding to the other three limiting blocks are moveably connected in the rotating rings in the base in an insertion manner. According to the railway overhead line system bird repellent fixing equipment for preventing rotation or dissociation, the device is fixedly mounted on angle steel of an overhead line system through the bolts, the vertical grooves are formed in threads of the bolts, after being screwed, the bolts are tightly clamped through the limiting blocks, then thebolts cannot be rotated, bolt loosening can be avoided, and a bird repellent can be safely and solidly mounted.

Description

technical field [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a bird repelling device fixing device for a railway catenary to prevent rotation and shedding. Background technique [0002] There are often birds nesting on the catenary framework of electrified railways such as high-speed railways and turtle trams. The branches and iron wires and other sundries when birds nest, as well as bird excrement, can easily cause short circuits in power supply lines. The bird repellent is installed on the catenary to drive the bird. In order to ensure that the distance between the bird repellent and all the live parts of the catenary maintains a sufficient safe insulation distance, the bird repellent is mostly installed on the angle steel of the catenary frame, which makes the bird repellent The installation structure of the bird repellent is limited to a semi-closed structure. The general bird repellent mainly uses bolts and ...
