Embodiment Construction

[0030] A turntable turnout, which is formed by crossing two sets of rails, is an X-shaped turnout with four side rails, including a turntable running beam, an arc-shaped connecting plate, a supporting beam, an outer guard welding plate, an edge guard plate, and a guide rail. The composition of the flat raceway, the central shaft, the lock pin device, the hydraulic control device, the electrical control device, the roller assembly, the stop raceway, the guide beam and related fasteners are characterized in that the middle of the turntable switch is The movable circular turnout track, the four side rails are fixed tracks, directly connected to the line track, and the line track is the track on the periphery of the turntable turnout. The turnout track and the fixed track are composed of guide beams in the middle, which play a guiding role, and the two sides are runways, which play a carrying role. The turnout track is divided into upper and lower parts: the upper part is equipped...

Abstract

The invention relates to the technical field of subway rails, in particular to a rotary disk turnout. The middle area of the rotary disk turnout is provided with a movable turnout rail, and four side rails are fixed rails. The upper part of the turnout rail comprises connecting rotary disk running beams formed by an upper framework and a support beam, a guide beam is arranged on the middle of the turnout rail, the rotary disk running beams are arranged on two sides, an outside protective welding plate is arranged outside the rotary disk running beams, and a roller assembly is arranged on the lower end of the support beam; the upper part of the turnout rail is connected with the lower part of the turnout rail through a transmission shaft and a pivotal bearing assembly, the lower part of the turnout rail is supported by a lower framework, a flat rail assembly and a stop raceway assembly are arranged on the ground around the lower framework; guide beams are respectively arranged on the middles of the four fixed rails, a locking pin device is arranged on the end part of each guide beam, and a hydraulic control device is arranged on a neutral gear between the two fixed rails, and is connected through a pipeline for centrally controlling the four locking pin devices and the rotary device on the center of the rotary disk turnout. The invention provides a matched rail changing technology for Guangzhou subway walking system, and can realize linear guide when the rails are crossed.

Description

technical field [0001] The invention relates to the technical field of urban subway turnouts, in particular to a running system for subway turnouts. Background technique [0002] Urban rail transit technology projects have been rapidly developed in my country in recent years. They are mainly used for large-capacity urban passenger transportation and are an effective means to improve traffic congestion in large cities. [0003] The problem of traffic congestion in my country's big cities is becoming more and more serious, and urban rail transit is being built one after another. Because each city independently raises funds, builds and manages independently, and lacks unified system research and development and management, some new systems and new equipment lack relevant supporting facilities. [0004] Guangzhou Zhujiang New Town Passenger Automatic Conveyor System is the world's first underground fully automatic driverless subway, and all trains have realized automatic contro...
