Example Embodiment

[0019] Example 1: Refer to the attached figure 1 . A switch line shape of a joint flexible switch flexure device includes a fixed end of a switch, a side line position of a movable end, and a straight line position of the movable end. A gentle curve is formed between the fixed end of the switch 501 and the arc curve. Between the curve and the position 502 of the side line of the movable end is a gentle curve. The reference number 503 is the linear position of the movable end. That is, the turnouts of Japan and Chuandong Shipyard adopt a single circular curve linear design. In use, there will be a hard point transition in the connection part in the line; at the same time, due to the influence of the beam width, there will be about 3mm wrong teeth on the guide surface and the stable surface of the open end. The turnout alignment designed in this application takes into account the influence of the concrete beams at both ends. The deflection curve adopts the combination method o...

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...
