Problems solved by technology

During the trial operation of the suspended monorail traffic track, a problem emerged: the telescopic device at the beam end expands and contracts with the heat and cold of the bridge, and the gap is small in summer and large in winter. When the train passes the telescopic device with a large gap, The train shook violently and made a lot of noise, causing great distress to passengers and nearby residents

Embodiment 1

[0023] Such as figure 1 with 2 Shown, a kind of suspension type rail transit telescopic device comprises two steel beams 9 mutually symmetrically arranged, forms gap between two steel beam bottom plates 10, and the seam place of two steel beams 9 forms telescopic connection respectively by telescopic device, two The telescopic devices at the joints of the steel beams are arranged symmetrically to each other. By fixing the telescopic devices at the joints of the steel beams 9, the steel beams 9 on both sides of the joint form a telescopic connection, and the telescopic devices adopt the first toothed plates that mesh with each other. 1 and the second toothed plate 2, the first toothed plate 1 and the second toothed plate 2 are fixed on the bottom plate of the steel beam 9 by bolts 3, when the steel beam 9 expands and contracts at the joint due to temperature changes, the two teeth The toothed plates move through the mutual meshing between the comb-shaped teeth, and then adapt ...

Embodiment 2

[0025] In this example, if figure 2 As shown, the bottom surface of the steel beam bottom plate 10 is fixedly connected with the base 5 located under the telescopic device by welding. The base 5 is used to enhance the vertical bearing capacity of the telescopic device, so that the comb-shaped teeth are not prone to the risk of broken teeth and warped teeth. Affecting the normal operation of the train, the base 5 includes a connecting plate 51, a side plate 52 and a limit block 54, the top surface of the connecting plate 51 is welded and fixed to the bottom surface of the steel beam bottom plate 10, and the side plate 52 and the limit block 54 are welded on the bottom surface of the connecting plate 51 and A U-shaped cavity is formed with the connecting plate 51, and a guide limiting plate 4 is arranged in the U-shaped cavity. The guiding limiting plate 4 straddles the seam and is fixedly connected with the connecting plate 51 through the anchor bolt 6. The side plate 52 and th...

Embodiment 3

[0027] In this example, if figure 2 As shown, on the side plate 52 and the limit block 54, the screws 7 for adjusting the lateral position of the guide limit block 4 are relatively provided, and the screws 7 pass through the side plate 52 and the limit block 54 respectively, and the screws 7 on the left and right sides Elasticity, the lateral position of the guide limit block 4 can be adjusted, so that the lateral misalignment of the two toothed plates can be adjusted. When the lateral position of the two toothed plates is adjusted to a suitable position, the tooth engagement of the comb teeth of the two toothed plates will be the best. Then tighten the screw 7 and the anchor bolt 6 to limit the lateral displacement of the two toothed plates.

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...
