Positioning wire clamp device of high-speed railway catenary

Abstract

The invention relates to a positioning wire clamp device of a high-speed railway catenary. Semicircular slots are symmetrically formed in the middle parts of the top ends of a main clamping plate and a secondary clamping plate, and rectangular through holes are symmetrically formed in plate bodies of the main clamping plate and the secondary clamping plate below the two semicircular slots; a first annular boss is arranged on the end of a positioning pin, and a second annular boss is arranged in the middle of the positioning pin; the positioning pin is clamped between the main clamping plate and the secondary clamping plate, the first annular boss is positioned in the rectangular through holes, the second annular boss is positioned in the upper groove of the two semicircular slots, and the positioning pin is clamped on the main clamping plate and the secondary clamping plate, so as to be positioned; bosses and grooves are respectively arranged on and formed in both sides of the inner end surfaces of the upper parts of the main clamping and the secondary clamping plate, the bosses and the grooves are distributed on and in both sides of the slots, the boss arranged on one side of the inner end surface of the upper part of the main clamping plate is embedded into the groove formed in one side of the inner end surface of the upper part of the secondary clamping plate, and the boss arranged on the other side of the inner end surface of the upper part of the secondary clamping plate is embedded into the groove formed in the other side of the inner end surface of the upper part of the main clamping plate. The positioning wire clamp device of the high-speed railway catenary has the advantages of good structural symmetry of the clamping plates, small quantity of assemblies, high visibility in installation, convenience in installation, safety and reliability.

Description

technical field [0001] The invention belongs to equipment for erecting an electrified railway catenary, in particular to a high-speed railway catenary positioning line clamp device. Background technique [0002] The positioning clamp is one of the key components in the electrified railway catenary system, and it is usually used in conjunction with a positioner to connect and fix the catenary. [0003] At present, there are mainly two types of positioning clamps used in my country's high-speed railway catenary system: the first is the U-shaped pin type, and the second is the pinless type with U-shaped bosses on the clamp body. When the U-shaped pin type positioning clamp is installed on site, it is greatly affected by the operation level of the personnel. If the U-shaped pin is not installed in place, the U-shaped pin may be severely worn at the joint of the anchor section and the locator and the positioning clamp may be damaged. out of the way, causing a traffic accident. ...

AI Technical Summary

Problems solved by technology

These two positioning clamps have the same function and similar structure. The second positioning clamp is an improved version of the first one. Although the U-shaped pin is canceled, the visibility of the internal fit is also not high. The structure of the ring splint is quite different, the force of the two is uneven, and the installation is complicated. There is room for further improvement.
