Single crossover turnout

Abstract

The invention provides a single crossover turnout. The single crossover turnout comprises a first beam; a first auxiliary beam positioned at one end of the first beam; a second beam positioned in oneside of the first auxiliary beam; a second auxiliary beam positioned at one end of the second beam; a first rail lifting assembly arranged at one end, close to the first beam, of the first auxiliary beam; a second rail lifting assembly arranged at one end, close to the second auxiliary beam, of the second beam; and a driving assembly connected to the first beam and the second beam. According to the single crossover turnout, when the driving assembly drives the first beam to rotate, the first rail lifting assembly rotates in the direction away from the first beam, and avoidance between the first beam and the first auxiliary beam is realized; when the driving assembly drives the second beam to rotate, the second rail lifting assembly rotates in the direction away from the second auxiliary beam, receding of the second auxiliary beam or the first beam is achieved, a stacked beam does not need to be arranged, the distance between the first beam and the second beam can be reduced, and the switching speed of the straight line position and the side line position is increased.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a single crossover turnout. Background technique [0002] In the field of rail transit, especially the low-speed maglev single-crossing turnout is usually composed of two standard single-opening turnouts plus an intermediate pile beam. The turnout is rotated and docked with the middle stacking beam; on the one hand, because there is a stacking beam in the middle, in order to ensure that the train passes through the safety limit of the straight line position of the turnout and the side line position of the turnout, the line spacing of the turnout area usually needs to be more than 6m, and the line spacing of the main line is generally at It is about 4.4m, so it is necessary to set a relaxation curve between the main line and the turnout, which will affect the passing speed of the train. At the same time, the too wide line spacing will increase the construction cost of the line; The bu...

[0002] In the field of rail transit, especially the low-speed maglev single-crossing turnout is usually composed of two standard single-opening turnouts plus an intermediate pile beam. The turnout is rotated and docked with the middle stacking beam; on the one hand, because there is a stacking beam in the middle, in order to ensure that the train passes through the safety limit of the straight line position of the turnout and the side line position of the turnout, the line spacing of the turnout area usually needs to be more than 6m, and the line spacing of the main line is generally at It is about 4.4m, so it is necessary to set a relaxation curve between the main line and the turnout, which will affect the passing speed of the train. At the same time, the too wide line spacing will increase the construction cost of the line; The butt end of the track beam is processed into a hypotenuse or arc shape, which leads to high production cost of the track beam, and the setting of the hypotenuse or arc shape will lead to a large joint gap of the track beam, which will affect the smooth operation of rail vehicles
