Abstract

The invention discloses a preparation method of an overhead line supporting device. The preparation method comprises the following steps of (1) core material processing, (2) core material splicing and (3) integral forming, wherein in the core material processing, core materials are processed into a flat cantilever (1), an oblique cantilever (2), an arc arm (3) and a connecting arm (4); and in the core material splicing, the core materials are spliced and fixed with connecting parts. The integral forming method of the overhead line supporting device realizes simple and efficient preparation of the supporting device, and meanwhile, the prepared overhead line supporting device is light, high in strength and good in insulating property.

Description

technical field [0001] The present application relates to the technical field of electrified rail transit, in particular to a method for forming a catenary support device. Background technique [0002] The catenary is a transmission line erected along the rail transit line to supply power to electric locomotives. It operates in an outdoor complex environment, and its stability and safety are directly related to the operation safety of rail transit. The catenary support device is installed on the support column to support the suspension of the catenary and play the role of load transfer. In actual use, the suspension device is required to have sufficient mechanical strength, and the structure is as simple as possible, light and handy, and easy to install, maintain and replace. [0003] And the existing catenary supporting device is mainly a steel arm supporting device and an aluminum alloy arm supporting device. These two support devices are composed of more than a dozen or...
