Positioning and connecting hook for electrical contact line in high speed railway

Abstract

The invention relates to the technical field of fittings for a contact line, and in particular to a positioning and connecting hook for an electrical contact line in a high speed railway. The positioning and connecting hook is provided with a hanger which is fixed in the middle part of a rectangular pipe; the root of the hanger is equipped with an integral compensation wire fixed structure; and a contact position between the hanger and the rectangular pipe is equipped with a chamfer angle with the radius of 2mm-5mm. The positioning and connecting hook has the beneficial effect that line contact between the positioning hook and the rectangular pipe becomes surface contact by setting the chamfer angle, thus enhancing the fatigue strength and prolonging the service life of the product.

Description

technical field [0001] The invention relates to the technical field of catenary components, in particular to a positioning connecting hook for a high-speed railway electrified catenary. Background technique [0002] In recent years, with the rapid development of social economy, higher requirements have been put forward for railway transportation. In order to adapt to the continuous speed increase of railways under the new situation, higher requirements have been put forward for the technical requirements of catenary components. The positioning hook in the catenary component is a part of the rectangular positioner device, which is used to fix the contact line in the electrified railway catenary system. The current positioning hooks are all fixed at the tail of the rectangular tube and are forged and trimmed. Because the positioning hook is forged and cut Behind the edge, there is residual flash. When the rectangular locator vibrates, the tail of the positioning hook contacts ...

Problems solved by technology

The positioning hook in the catenary component is a part of the rectangular positioner device, which is used to fix the contact line in the electrified railway catenary system. The current positioning hooks are all fixed at the tail of the rectangular tube and are forged and trimmed. Because the positioning hook is forged and cut Behind the edge, there is residual flash. When the rectangular locator vibrates, the tail of the positioning hook contacts the rectangular pipeline, which causes fatigue fracture of the rectangular tube, reduces the service life of the product, and brings safety hazards to the entire catenary system.
