Description

Rail transit elevated line evacuation platform terminal and station platform connection cab apron device

Technical Field

The utility model belongs to the evacuation equipment of track traffic personnel, specifically speaking, in particular to cab apron device is connected to sparse platform terminal of track traffic overhead line and station platform.

Background

As an important line laying mode, the overhead line of the urban rail transit has the advantages of flexible line selection, engineering economy, saving and the like, and meanwhile, the risk of difficult crowd evacuation under the condition of an accident on the viaduct exists. At present, the arrangement of an evacuation platform on a rail transit overhead line becomes a novel engineering practice for improving the safety of the line. For example, the magnetic levitation railway in China mostly adopts an elevated line, and the bottom of the magnetic levitation train of the electromagnetic levitation system surrounds the track, so that the elevated line track structure lacks a necessary running space for emergency evacuation of people, and the evacuation of people is difficult. For safety requirements, the design specifications of the existing medium-low speed magnetic levitation railway are stipulated, and special evacuation platforms are required to be arranged along the overhead line of the medium-low speed magnetic levitation railway for emergency evacuation of passengers.

However, the detailed design requirements of the current design specifications of urban rail transit on the elevated line evacuation platform are still at the early stage, and after passengers enter the elevated station area through the evacuation platform between the line sections, the connection mode between the terminal of the evacuation platform and the platform is not specified in detail, so whether the terminal in the evacuation platform and the platform can be connected quickly and reliably becomes an important influence factor for realizing safe evacuation of personnel. Taking the evacuation of personnel on an elevated line of a magnetic levitation railway as an example, when an evacuation platform is positioned in the middle position of a double-line, the existing evacuation platform terminal and platform connection modes mainly comprise two modes, namely, the evacuation platform terminal and the platform are connected by virtue of an in-station train, namely, passengers enter the train from the evacuation platform and then enter the platform by virtue of a magnetic levitation train stopped in the station during evacuation; the other is that the movable connection cab apron is arranged in the station, namely, two ends of the cab apron are respectively put on the station platform and the evacuation platform terminal for passengers to walk in emergency evacuation. Both of these connection methods have significant disadvantages, in particular: when the train in the station is connected, the train needs to stop in the station by the maglev train to assist the evacuation of passengers, and because the emergency evacuation accident is sudden, the difficulty of emergency train scheduling is large, the time is long, the cost is high, the reaction speed is slow, the train can not be just guaranteed to stop in the station for evacuation, and the emergency movement of the train has great influence on the operation of the whole train. If a severe power interruption accident of a maglev train power supply system occurs, the dispatching and the use of the maglev train for connection cannot be guaranteed; although the second mode of manually putting the cab apron can also realize the connection between an evacuation channel and a station platform, the connection mode has low automation degree and poor flexibility, personnel allocation is difficult to guarantee during an accident, the track structure of a magnetic suspension train needs to be spanned during manual erection, and if the cab apron accidentally falls, the fine track structure (such as the geometric shape and position of an induction plate) of the magnetic suspension railway is easily damaged. In addition, the two ends of the cab apron are not easy to fix, manual locking is difficult to achieve, and the cab apron is easy to shift under the action of dynamic load of people when a large number of passengers walk and pass through.
