Beam-changing type turnout structure for suspension type rail transit and switching method

Abstract

The invention discloses a beam-changing type turnout structure for suspension type rail transit and a switching method. The beam-changing type turnout structure comprises a front door frame beam, a front driving device, a front sliding block device, a first turnout curved beam, a turnout straight beam, a second turnout curved beam, a rear door frame beam, a locking device, a rear driving device and a rear sliding block device, wherein the first turnout curved beam and the second turnout curved beam are arranged on the two sides of the turnout straight beam respectively and are of a symmetricalstructure; the upper portions of the front ends of the first turnout curved beam, the turnout straight beam and the second turnout curved beam are connected to a front sliding block device through front pin shafts; the upper portion of the rear end of the front sliding block device is connected to a rear sliding block device through a rear pin shaft; and the front sliding block device and the rear sliding block device are located in sliding grooves of the front door frame beam and the rear door frame beam respectively and connected with a front driving device and a rear driving device throughinstallation bases respectively. Therefore, the beam-changing type turnout structure for suspension type rail transit is high in linear motion positioning precision, reliable in performance, high inrigidity, small in stress deformation, capable of improving the alignment precision of the turnout beam and low in manufacturing and machining cost.

Description

technical field [0001] The invention relates to the technical field of suspended rail traffic, in particular to a beam-changing turnout structure and switch method for suspended rail traffic. Background technique [0002] With the rapid development of urban rail transit, operating vehicles have high loads and frequent stops to transport a large number of passengers. Suspended vehicle line change equipment is used for line change equipment when entering and exiting stations and parking lots during the operation of vehicles suspended in the air. When the suspended monorail vehicle is in operation, when it enters and exits the station and enters and exits the parking lot, it needs to perform line switching, and when it reaches each station, maintenance point, and garage, it can realize line switching that requires line changing equipment. The prior art has defects such as complex structure and cumbersome actions. [0003] There are two types of suspended monorail traffic swit...

AI Technical Summary

Problems solved by technology

The turnout is an integral type with a total length of about 20 meters. It is bulky and difficult to manufacture, process, and transport. The translational turnout is currently driven by a rack and pinion with external leakage, and the operating accuracy is not enough. reduce
