A method for forming a catenary support device

Abstract

Disclosed is a molding method of an overhead contact system supporting device. The molding method comprises the following steps that (1) a core tube is processed, wherein the core tube is processed to form a flat cantilever, an inclined cantilever, an arc-shaped arm and a connecting arm; (2) after glass fibers are wound around the core tube, splicing adhesion is conducted; or after splicing adhesion of the core tube is accomplished, the glass fibers are wound around the core tube; and (3) mold combination, RTM resin transfer molding injection and heating solidification molding are conducted, wherein adhesive injection channels of a mold are formed in the portions below the flat cantilever and the inclined cantilever, the inner side of the arc-shaped arm, the portion above the connecting arm and the portion above the part, located between the flat cantilever and the connecting arm, of the inclined cantilever, air pumping channels are formed in the portion above the flat cantilever, the portion above the part, far away from the connecting arm, of the inclined cantilever, the outer side of the arc-shaped arm and the portion below the connecting arm, and air pumping openings are formed in the portion, located between the flat cantilever and the connecting arm, of the inclined cantilever. By the adoption of the molding method of the overhead contact system supporting device, the supporting device is easily and efficiently manufactured, and the manufactured overhead contact system supporting device is light in weight, 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...

AI Technical Summary

Problems solved by technology

These two kinds of supporting devices are composed of more than a dozen or even dozens of parts connected by hinges and bolts. The installation and maintenance workload is heavy and the construction quality is difficult to guarantee. At the same time, the price of insulators is also relatively high.
