Shaft journal type railroad turnout

Abstract

The invention relates to the technical field of railroad turnout of city subways, in particular to a shaft journal type railroad turnout which comprises three sections including a fixed track, a railroad turnout track and a tail end track; the fixed track is provided with a front support and a rear support, and a fixed guide beam is paved in the middle of the fixed track; hydraulic pipelines of locking devices are connected with a switching control system in the back of the railroad turnout track and is controlled by a set of hydraulic system in a centralized manner; a raceway cross beam assembly, a backstop raceway cross beam group and a railroad turnout cross beam assembly are arranged at the lower part of the railroad turnout track; a movable straight guide beam assembly and a movable bent guide beam assembly are fixed at the upper part of the railroad turnout track; steel structure framework assemblies are mounted on the two sides of the railroad turnout track; the switching control system is mounted in the middle of the guide beam assembly and beside the backstop raceway cross beam group; and running beams are arranged on the two sides of the tail end track, and a straight tail end guide beam and a bent tail end guide beam are arranged in the middle of the tail end track. The shaft journal type railroad turnout is controlled through an automatic control system and can also be operated by people remotely or shortly, can meet the requirements of automatic section guiding when subway vehicles pass by the joints of track branches smoothly, and can guarantee carrying quality and efficiency of railroad turnout.

Description

technical field [0001] The invention relates to the technical field of urban subway turnouts, in particular to a pivot-type turnout. 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 systematic research and development and unified management, some systems and equipment often lack supporting equipment. [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 control. The unmanned transpo...
