Abstract

The invention discloses a tramcar contact line sliding type elastic suspension device. The tramcar contact line sliding type elastic suspension device comprises a rigid cantilever. The rigid cantilever is of a square tube structure, the inner end of the rigid cantilever is fixed to a supporting column, and a positioning supporting seat is fixed to the outer end of the rigid cantilever through U-shaped bolts. An insulation positioning tube is elastically hinged to the positioning supporting seat. A holder is fixed to the outer end of the insulation positioning tube. A sliding block is horizontally fixed to the lower portion of the holder. A horizontal sliding rail is installed on the sliding block. Groove clamping plates are arranged on the lower portion of the horizontal sliding rail. The problems that existing contact line suspension devices are complex in structure and large in occupied space are solved, and the tramcar contact line sliding type elastic suspension device has the characteristics of being simple in structure, light, handy, high in space utilization rate and the like.

Description

technical field [0001] The invention belongs to the technical field of a tram contact wire suspension device, and in particular relates to a sliding type elastic suspension device for a tram contact wire. Background technique [0002] Tram, as an important mode of urban rail transit, has become an important trend in the development of urban transportation in the future. At present, the flexible and simple suspended catenary power supply method is favored by major cities because of its low cost, convenient maintenance, and good operating efficiency. It can make full use of limited construction funds to solve potential traffic pressure. However, each suspension point includes structures such as flat wrist arms, cable-stayed wires, positioning supports, locators, and slings, which take up a lot of space, are not conducive to the overall planning of the line, are easy to increase design costs, and are not easy to meet in terms of landscaping. Require. Contents of the inventio...
