Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the terminal anchoring structure of the existing high-iron-copper alloy contact wire in the prior art is in use, the contact wire is prone to thermal expansion and contraction under the influence of the external temperature. , the contact wire will shrink, which will easily cause a gap between the splint and the contact wire, resulting in loosening of the contact wire, thus affecting the fixation stability of the contact wire. A high-iron-copper alloy contact wire is proposed Terminal anchor clamp mechanism

Abstract

The invention discloses a terminal anchoring wire clamp mechanism for a high-iron copper alloy contact wire, which comprises a shell, a three-jaw chuck is fixedly mounted on the shell, a contact wire body penetrates through the middle part in the three-jaw chuck, a plurality of sliding blocks are mounted at the front end of the three-jaw chuck, and fixed clamping plates are fixedly mounted at ends, close to the contact wire body, of the sliding blocks; a movable clamping plate I is arranged in the middle of one side, close to the contact wire body, of each fixed clamping plate; and movable clamping plates II are symmetrically arranged on two sides of each movable clamping plate I. When the terminal anchoring wire clamp mechanism is used, the fixed clamping plates and springs I are matched with the fixed clamping plates, the movable clamping plates I and the movable clamping plates II, so that the fixed clamping plates, the movable clamping plates I and the movable clamping plates II can synchronously stretch out and draw back when the contact wire body expands with heat and contracts with cold, and the phenomenon that the contact wire body contracts with cold due to cold temperature in winter is avoided; therefore, the contact wire body is loosened from the fixed clamping plates, the movable clamping plates I and the movable clamping plates II, and the fixing stability of the contact wire body is improved.

Description

technical field [0001] The invention relates to the technical field of high-speed iron contact wires, in particular to a terminal anchoring clamp mechanism for high-iron copper alloy contact wires. Background technique [0002] The contact wire mainly refers to the contact wire used for the electrified railway catenary. Its structural characteristics are copper, copper-silver alloy, high-strength copper-silver alloy, copper-tin alloy, copper-magnesium alloy, high-strength copper-magnesium alloy, etc. Railway catenary needs. Various contact wires such as copper, copper-silver alloy, high-strength copper-silver alloy, copper-tin alloy, copper-magnesium alloy, and high-strength copper-magnesium alloy can be provided in accordance with the Ministry of Railways TB / T2809. [0003] When the terminal anchoring structure of the existing high-iron-copper alloy contact wire is in use, the contact wire is prone to thermal expansion and contraction under the influence of the external te...
