Bending device of joint flexible turnout

Abstract

The invention relates to a bending device of a special rail transfer joint flexible turnout for straddle type monorail traffic line. The bending device comprises guide panels, stabilization panels, mount supports, cam support shafts, axial cams, double-plug connecting rods, roller assemblies, a connecting rod pair and an electric push rod, and adopts a cam and pull rod series connection driving form to realize synchronous bending of a guide surface and a stabilization surface; the guide panels and the stabilization panels are connected with the two ends of the double-fork-head pull rods by reamed holes; the double-fork-head pull rods are connected with driven components; the driven components are contacted and connected with cylindrical cam mechanisms; the above two adjacent cylindrical cam mechanisms and the two vertically corresponding cylindrical cam mechanisms are connected by connecting rods; when the electric push rod starts to push and pull, the pull rod drives the guide panels to move transversely and synchronously, and therefore, the transverse bending of the guide panels is accomplished.

Description

technical field [0001] The invention relates to a joint-flexible turnout flexure device used in a straddle-type monorail traffic line, which 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 vehicle is 15Km / h, which can...

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
