Problems solved by technology

However, in the design of Shenzhen Line 8, the line spacing of the entire line is 4.6m. If a 6.23m spacing single-crossing turnout is used, the line spacing in the turnout area will increase, so a transitional curve needs to be designed near the turnout. The area occupied by the turnout area Relatively large, it will affect the design of the station
The existing turnout with a line spacing of 6.23m is composed of two sets of single-opening turnouts and intermediate pile beams. Its structure is as follows: Picture 1-1 , 1-2 , 1-3: the double-dotted line in the figure is the vehicle, and the safety distance when the vehicle passes through the turnout is S. In order to ensure that the vehicle passes through the turnout, the minimum distance between the lines should be 6.23m, that is, L 车宽 +L 轨道宽 +2S=3.36+2.2+2X0.335=6.23m, this kind of turnout cannot be used on the line with a line spacing of 4.6m, and the versatility is poor

Embodiment approach

[0038] Overall structure plan:

[0039] 1. Beam structure

[0040] Two single turnouts are used for docking, and the middle stacking beam is removed. In order to allow vehicles to pass safely at the position of the side line, an avoidance beam is added. Vehicles pass through the line, and the straight line position fully meets the vehicle limit requirements. In order to ensure that vehicles pass laterally from the turnout to meet the limit requirements, as shown in the figure: L 车宽 +L 轨道宽 +2S=3.36+2.2+2X0.335=6.23m. In order to allow vehicles to pass safely, the fixed beams in the past are designed as avoidance beams and moved a certain distance to allow vehicles to pass smoothly.

[0041] 2. Beam follower mechanism

[0042] In order to move the avoidance beam, a set of beam follower device is designed. The main beam is driven by a motor to drive the crank to drive the turnout beam to move. The avoidance beam does not design an independent drive system, but a set of followe...

Abstract

A medium and low speed magnetic levitation small linear interval single-crossover turnout is characterized by comprising two lateral turnouts in butt joint, an avoiding beam is arranged on one side of each lateral turnout and provided with a beam body servo device enabling the avoiding beam to move away, and meanwhile a fixed end stack beam is connected with the tail end of each avoiding beam. The linear interval of the crossover turnout is reduced from 6.23 m to 4.6 m and can meet the requirement of a 4.6m-interval road, the occupied space and difficulty of overall design of the road are reduced, and the overall manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of railway turnouts, in particular to the improvement of maglev railway turnouts. Background technique [0002] The "S1 line" of the Beijing medium and low speed maglev demonstration line is China's first medium and low speed maglev commercial operation demonstration line. In 2010, a single crossover turnout was used on this line. The turnout is composed of two sets of single turnouts with stacking in the middle The combined form of the beams, the line spacing is 6.23m. However, in the design of Shenzhen Line 8, the line spacing of the entire line is 4.6m. If a 6.23m spacing single-crossing turnout is used, the line spacing in the turnout area will increase, so a transitional curve needs to be designed near the turnout. The area occupied by the turnout area It is relatively large and has an impact on the design of the station. The existing turnout with a line spacing of 6.23m is composed of two sets of sin...
