Problems solved by technology

[0002] In the related art, the transition between the flexible plates at the fixed end and the movable end of the turnout and the guiding surface and stable surface of the connected track beam, and the finger joint plate between adjacent flexible plates is poor, resulting in the poor transition of the vehicle through the turnout. When there is a hard impact, on the one hand, the vehicle swings and shakes obviously, which reduces the comfort of passengers; on the other hand, due to the large impact, the life of the vehicle bogie and turnout equipment is seriously reduced
[0003] In addition, some turnout beams improve the smoothness of joints by setting relaxation curves at both ends of the fitting circular curve, so as to reduce the impact and improve the comfort of passengers. It requires a combination of complex deflection drive system and control system to achieve such a linear shape, which is difficult to debug and expensive

Abstract

The invention discloses a joint flexible turnout flexure plate device and a turnout structure. The joint flexible turnout flexure plate device comprises: a plurality of sections of flexural plates arranged in a track shape and spaced apart in sequence, and two ends of each section of the flexural plates are respectively provided with a fixed mounting support and a movable mounting support, whereinthe ends of the adjacent two flexural plates adjacent to each other are provided with a fixed mounting support or both are provided with a movable mounting support. The joint flexible turnout flexureplate device according to the invention is compact in structure and reasonable in layout, is favorable for forming a stable and reasonable flexure curve shape, reduces impact and improves vehicle ride comfort.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a joint-flexible turnout flex plate device and a turnout structure. Background technique [0002] In the related art, the transition between the flexible plates at the fixed end and the movable end of the turnout and the guiding surface and stable surface of the connected track beam, and between the adjacent flexible plates is poor, resulting in poor transition of the vehicle through the turnout. When there is a hard impact, on the one hand, the vehicle swings and shakes obviously, which reduces the comfort of passengers; on the other hand, due to the large impact, the life of the vehicle bogie and turnout equipment is seriously reduced. [0003] In addition, some turnout beams improve the smoothness of the joints by setting relaxation curve sections at both ends of the fitting circle curve, so as to reduce the impact and improve the comfort of passengers. It is necessary t...
