Embodiment Construction

[0019] refer to figure 2 , the self-tightening busbar elastic clamp used for the overhead rigid catenary of the electrified railway, including the hanging rod 1 used to connect with the steel beam, and the top connecting head 11 is made with a through hole for passing the insulator and the steel beam. rack suspension connection. The cylinder body 5 is made of stainless steel, and a cylindrical rubber elastic layer 3 with a shaft hole is installed inside. The thickness of the rubber elastic layer is selected within the range of 10-65mm under the premise of ensuring the elastic force. There is a gap between the cylinder wall 51 and the rubber elastic layer 3 for the rubber elastic layer to be compressed and deformed. The top and bottom surfaces of the rubber elastic layer are respectively provided with a top plate 2 and a bottom plate 4, and the top plate 2 is welded to the top of the cylinder body. , constitute the top cover of cylinder 5. The diameter of the bottom plate 4 ...

Abstract

The invention belongs to the field of electrified railway contact networks, and relates to a self-clinching chucking busbar elastic wire clip, which comprises a hang lever (1) used for being connected with a steel girder, and a cylinder body (5) in which a rubber elastic layer (3) is arranged, and is characterized in that: the top surface and the bottom surface of the rubber elastic layer (3) are provided with a top plate and a bottom plate respectively, wherein the top plate serving as a top cover is fixedly connected with the top of the cylinder body (5); the bottom plate moves relatively to an inner wall of the cylinder body (5); the hang lever is fixedly connected with the bottom plate after running through the top plate and the rubber elastic layer (3); and a snap-gauge part at the top of a wire clip (6) extends to an inner bottom surface of the cylinder body (5). Through the design of the wire clip, the deadweight loadings of a busbar and a contact line is borne by the bottom plate in the cylinder through the rubber elastic layer, and the bearing area is large, so that the wire clip effectively reduces the abrasion of an overhead rigid contact network and the impact of pantograph, ensures that the pantograph operate more smoothly, has good current collection effect, reduces the wear of the contact line, has high reliability, and prolongs the service life of the contact line; and meanwhile, the parts are particularly convenient to process and install so as to contribute to reducing the construction investment and running costs of the contact networks.

Description

Technical field: [0001] The invention relates to a bus bar elastic clamp, which belongs to the field of electrified railway catenary. Background technique: [0002] The elastic clamps for overhead rigid catenary are used to fix and support the rigid catenary busbar. With the rapid development of urban rail transit construction, it is the general trend for rigid overhead catenary to replace flexible overhead catenary due to its maintenance-free advantages. The rigid catenary is installed on the channel steel beams at the top of the tunnel using rigid support insulators. There is an existing busbar elastic clip, such as figure 1 As shown, the shaft center of the mandrel 4 filled with epoxy resin is embedded with a bolt 1 for fixing to the steel beam fixed on the inner roof of the tunnel, and a rubber elastic layer 3 is formed between the inner wall of the cylinder and the mandrel, and the rubber is elastic. Layer 3, bolt 1 and FRP mandrel 4 are made into a concave-convex cyl...
