Alignment of joint-flexible turnouts

Abstract

The invention relates to a turnout line shape of a joint flexible type turnout bending device. The turnout line shape is used for special track conversion in straddle type single track traffic. The turnout line shape comprises a turnout fixed end, a movable end lateral line position and a movable end straight line position. A buffer curve is arranged between the turnout fixed end and the circular curve, and a buffer curve is arranged between the circular curve and the movable end lateral line position. The turnout line shape has the advantages of adopting combination of a rotating line, a round curve and a rotation curve, ensures that impact changes slowly when cars passe through the line, cannot cause the existing product hard impact, is favorable for improving passenger comfort, and prolongs service life of a vehicle bogie and a turnout.

Description

technical field [0001] The invention relates to a turnout line shape of a joint-flexible turnout flexure device used in a straddle-type monorail traffic line, and belongs to the field of light rail line supporting equipment manufacturing. Background technique [0002] Joint-flexible turnout is a special track switching device used in straddle-type monorail transit lines. Currently, joint-flexible turnouts are produced by Hitachi Corporation in Japan and Chuandong Shipyard in China, and their products are used on the Chongqing Light Rail Line. The working principle of the turnout is: the articulated turnout is composed of multi-section beams. After the articulated turnout switches, the longitudinal direction of the turnout beam is in the shape of a broken line. The guiding surface and the stable surface of the articulated turnout are both planes. A large impact will occur when reaching the corner of the turnout beam joint, so the maximum allowable passing speed of the vehicl...

AI Technical Summary

Problems solved by technology

At present, the existing deflection device has the following characteristics: first, the deflection curve of the turnout adopts the form of a circular curve, but the impact is large when the vehicle enters and exits this part of the line; The length of the contact line is reduced, which is prone to early wear; the third is that the guide surface and the support of the stable surface need to be lubricated, which is not conducive to maintenance; the fourth is that the cam is manufactured as a whole, which is difficult to manufacture and the accuracy is not easy to guarantee; the swing arm uses Welded structure, difficult to install and adjust on site
