Problems solved by technology

However, after further research, the inventor found that the implementation of this method has higher requirements on the elastic deformation of the integrated track beam, and the deformation of the entire integrated track beam and the track above it is relatively large during bending and reversing. Significantly reduced service life of integrated track beams

Embodiment

[0057] Embodiments of the invention are achieved through the following technical solutions:

[0058] First of all, it should be noted that the X direction mentioned in this embodiment is the running direction of the first running rail 101; the Y direction is perpendicular to the running direction of the first running rail 101, and is in the The direction in the same horizontal plane; the Z direction is the direction perpendicular to the earth; and the first running rail 101 laid on the fixed beam 1 includes two first running rails 101 arranged in parallel, and the first running rail 101 laid on the same bifurcated beam 2 The second running rail 201 includes two second running rails 201 arranged in parallel.

[0059] Please refer to 1 to Figure 7 , a track beam turnout mechanism for rail transit, comprising a fixed beam 1 laid with a first running rail 101, the first running rail 101 and the fixed beam 1 form a main track part, and at least two of which are laid with a second...

Abstract

The invention relates to the technical field of rail transit, and discloses a rail transit track beam turnout mechanism, the rail transit track beam turnout mechanism comprises a fixed beam paved witha first traveling rail, at least two forked beams paved with a second traveling rail, a swinging beam arranged between the fixed beam and the forked beams, and a plurality of limiting devices arranged on the fixed beam and/or the swinging beam, wherein one end of each forked beam is an alignment end, and the limiting devices are used for limiting the movement of the first traveling rail at the turning position in the Y direction. The turnout mechanism provided by the invention realizes the line switching by independently arranging the swinging beams capable of swinging on the basis of simplifying the integral structure of the turnout mechanism and improving the line switching efficiency, and reduces the deformation of a variable track to the first traveling rail during the line switching,and the service life of the swinging beam and the integral stability of the turnout mechanism are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a track beam turnout mechanism of rail transit. Background technique [0002] The air rail transportation system is a special rail transportation system. In such a rail transportation system, the track is laid on a track beam supported in the air by support columns, and the corresponding rail vehicles run under the track. Based on the advantages of small footprint, low cost, and short construction period of the aerial rail transit system, the aerial rail transit system is also more and more used in urban transportation construction. [0003] Due to the complex and diverse characteristics of traffic lines, correspondingly, in the air rail transit system, there is also a situation where one main track corresponds to multiple branch tracks. In order to ensure the accurate running direction of rail vehicles, it is necessary to set up switch mechanisms in these areas. , to adju...
