Abstract

The invention discloses a suspension type rail transit telescopic device. The device comprises two steel beams which are symmetrically arranged; a gap is formed between the two steel beam bottom plates; joints of the two steel beams form telescopic connection through telescopic devices respectively; the telescopic devices at the joints of the two steel beams are symmetrically arranged and fixed toa steel beam bottom plate; each telescopic device comprises a first tooth-shaped plate and a second tooth-shaped plate which are meshed with each other; comb-shaped teeth on the first tooth-shaped plates are of an oblique tooth structure; and comb-shaped teeth on the second tooth-shaped plates are of an oblique tooth and straight tooth mixed structure. The suspension type rail transit telescopicdevice is simple in structure; the telescopic devices can be detached and replaced; excessive vibration generated when a train passes through the steel beam joints can be effectively avoided, so thatnoise is reduced.

Description

technical field

[0001] The invention relates to the technical field of suspended rail traffic, in particular to a telescopic device for suspended rail traffic. Background technique

[0002] The telescopic device of the bridge is an important part of the bridge structure, which plays an important role in ensuring the safety of the bridge structure and the smooth operation of the train. In recent years, with the rapid development of the country's rail transit industry, many new rail transit systems have emerged. The suspended rail transit system is also called the sky track, or empty track for short. Its characteristic is that the vehicle is suspended under the box-shaped track beam, and the track beam is supported in the air by steel columns or reinforced concrete columns. The running wheels and guide wheels of the vehicle are located in the box-shaped beam, and run along the track inside the beam body. During the trial operation of the suspended monorail traffic track, a p...
