Description

Technical Field

[0001] This invention relates to an ultra-wide telescopic gate suitable for railway platforms, which is used to separate the public area of ​​the platform from the train area in railway, high-speed rail, and intercity platforms. Background Technology Currently, most railway platforms do not have platform screen doors, posing a risk of passengers accidentally falling onto the tracks while waiting for their trains, especially during peak hours or in emergencies. Furthermore, high-speed rail platforms experience high passenger volume, diverse train types, and complex train formations, and the accuracy requirements for train stopping are relatively lower than those for subways. These factors place higher demands on the design of platform screen doors.

[0002] Existing subway platform screen doors come in two types: one with a typical passage width of 2000mm, which is incompatible with the approximately 2000mm gap between the doors of large railway trains; and another type using stacked doors, which are bulky and difficult to maintain and install. Neither of these two types meets the usage requirements of railway platforms. A new design was developed based on these two existing types of railway platform screen doors.

[0003] Designing an ultra-wide telescopic gate that can be modularly installed, uses lightweight materials, and has two-stage telescopic capability to meet the harsh operating environment of the platform and the need for ultra-wide (4000mm) passage width has become an urgent technical problem to be solved. Summary of the Invention The technical problem this invention aims to solve is to provide an ultra-wide retractable gate suitable for railway platforms. It features a two-stage independently controlled telescopic system, allowing precise control of the gate's opening and closing dimensions, with a maximum opening distance of 4 meters. It integrates audible and visual alarms, auxiliary guidance, and an intelligent system into a comprehensive protective device, addressing the lack of safety protection in existing railway platforms. This retractable gate has a two-stage telescopic function, with a telescopic width of approximately 4000mm to meet the high passenger flow and diverse train type requirements of railway platforms. A modular design and a non-metallic aluminum profile frame achieve lightweight construction for easy installation. Intelligent system control ensures the platform gate can adapt to different train types, formations, and stopping errors, achieving seamless connection with railway trains. The design of the platform gate needs to fully consider the complex environment of railway platforms and be able to adapt to different climatic conditions (high temperature, low temperature, rain, snow). This design provides a safe and reliable platform gate system for railway platforms, improving operational efficiency and reducing maintenance costs.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: An ultra-wide telescopic gate suitable for railway platforms, namely an ultra-wide telescopic gate symmetrically distributed on the left and right sides of the platform; The extra-wide telescopic gate includes a fixed gate installed on the side of the platform edge and a side box installed on the side of the fixed gate; A sliding door is telescopically installed on the side of the side box; A primary door drive system is installed on the side box; The primary door drive system includes a motor bracket housed in the side box; a motor is mounted on the motor bracket. The motor drive is connected by a drive belt; A slide rail is provided on one side of the transmission belt; A slider that moves left and right is provided on the slide rail; A hanging component is provided on the slider, and the hanging component is connected to the horizontal end of the hanging component.

Partition 7 is made of non-metallic materials to prevent passengers from passing through the gaps in the secondary door.

[0034] Electromagnetic lock 8 ensures that the sliding door can automatically lock when it slides to the closed position; when it needs to be opened, the door controller DCU9 controls the automatic unlocking function, and it can also be unlocked manually from the track side or platform side. The door control unit (DCU9) receives external signals and controls the primary and secondary door drive systems, thereby controlling the primary and secondary doors and transmitting relevant status signals of the platform door to the signaling system. The primary gate drive system 10 includes a motor, motor bracket, etc., which controls the movement of the primary gate and outputs signals to the gate controller DCU9. The local control box LCB11, where LCB stands for local control box, can control the extension and retraction of a single door unit locally and is generally used during maintenance. The transmission belt 12 is preferably a toothed belt or chain; The secondary gate drive system 13 includes a motor, motor bracket, etc., which controls the movement of the secondary gate and outputs a gate controller DCU9 as the signal.

[0037] Anti-deviation guide wheel 19 prevents the door from moving to the left or right and keeps it within the designated guide rail.

[0038] Profile guide rail 20 is used for the guide wheel to reciprocate on the fixed guide rail.

[0039] Train 21 is preferably a high-speed train or an intercity train; The basic structure of this utility model consists of a fixed door 1, a side box 2, a primary sliding door body 5, and a secondary sliding door body 6.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, the side box 2 is equipped with three doors that can be opened. The upper door is equipped with a control system. The control system includes an electromagnetic lock 8, a door controller DCU9 and a local control box LCB1. The upper door is equipped with a primary door drive system 10, which includes a primary motor, a transmission belt 12 and a slider 14. The middle door is equipped with a PIS screen 3, and it is convenient to inspect and maintain the secondary door drive system when it is open; After the lower door is opened, the bottom guide rail assembly of the primary door can be inspected, which includes anti-tipping guide rollers 18, anti-deviation guide rollers 19, and profile guide rails 20. Indicator light 4 is located on the upper side of side box 2, protruding beyond the top edge of the side box. Figure 6 As shown, the indicator lights at the end of the platform are also visible from the front of the platform, mainly serving a warning function. The primary sliding door body 5 is embedded in the side box 2 and can be fully retracted into the side box 2. The secondary sliding door body 6 is located inside the primary sliding door body 5, with a non-metallic transparent partition 7 in the middle. Anti-collision rubber strips 17 are installed on the facade of the secondary sliding door body 6. Both the primary sliding door body 5 and the secondary sliding door body 6 are composed of an aluminum alloy frame and a non-metallic outer shell.

[0041] like Figure 3 As shown, the electromagnetic lock 8 is located inside the side box 2, with the lock head extending to maintain the closed state of the sliding door. The local control box LCB11 and the door controller DCU9 are installed inside the side box 2 inside the side box 4. The function of the local control box LCB11 is to control the opening and closing of a single sliding door, which is generally used during maintenance. The function of the door controller DCU9 is to receive external signals and control the motor to start and stop, thereby driving the opening and closing of the first-stage sliding door 5 through the transmission belt 12, slider 14 and hanging component 15, or driving the opening and closing of the second-stage sliding door 6 through the traction component 16. It can also transmit the relevant status signals of the platform door to the platform door monitoring system and then to the signal system.

Door controller (DCU); 10. Primary door drive system; 11. Local control box (LCB); 12. Drive belt; 13. Secondary door drive system; 14. Slider; 15. Hanging component; 16. Traction component; 17.

Working principle: The extra-wide retractable gate forms an effective physical barrier between waiting passengers and trains entering and leaving the station. Pedestrians can obtain information such as vehicle, time, and weather on the PIS screen on the side box.

[0043] Before the train arrives at the station, the platform screen doors are closed, and the electromagnetic locks are in the off position, locking the doors. After the train enters the station and comes to a complete stop, the platform screen door monitoring system receives the opening command from the signal system and sends the opening command to the door controller (DCU) in each control box. Upon receiving the opening command from the DCU, the electromagnetic locks open, the sliding doors open, and the indicator lights emit a warning sound and flash. When the sliding doors are fully open, the warning sound disappears, and the lights remain on. The door controller (DCU) controls the primary drive system to rotate, which in turn drives the suspension components via a transmission belt, thereby opening the primary sliding doors. Simultaneously, it controls the secondary drive system to drive the traction components, opening the secondary sliding doors. The primary and secondary sliding doors open synchronously. Once the doors are fully open, the DCU sends an opening completion electrical signal to the platform screen door monitoring system.

[0044] When the train needs to depart the station, the DCU in the side box also receives a door closing command. The motor drives the primary sliding door to close via the transmission belt, and simultaneously controls the secondary drive system to close the secondary sliding door. After all sliding doors are closed, the electromagnetic lock closes, locking the sliding doors, and the indicator lights emit a warning sound and flash. When the sliding doors are fully closed, the warning sound disappears and the lights go out. After all sliding doors are closed and locked, a signal is sent to the platform door monitoring system that all platform doors are closed and locked, and this signal is transmitted to the signaling system. The signaling system then issues a departure command to the train.

[0045] Indicator lights provide warnings during the opening / closing of platform screen doors and in case of door malfunction. The outer surface of the anti-collision strip is made of a soft material and integrates sensors. If a person is touched during the closing of the secondary sliding door, the sliding door will stop closing and open in the reverse direction (or retreat a certain distance and remain stationary) to prevent passenger injury. The sensor setup is innovative, while the sensor electrical connection method is conventional.

[0046] There is a certain distance between the platform doors and the train, firstly to ensure passenger safety (refer to the platform safety line), and secondly to allow passengers and staff to walk between the platform doors and the train when the train is stopped.

[0047] Platform doors are installed on the platform, and to ensure their service life, all metal materials used are treated with anti-rust and anti-corrosion measures.

[0048] The position of the sliding door can be flexibly set according to the type of train that stops at the platform; if there are multiple types of trains that stop at the platform and the corresponding positions of the trains are different, an extra-wide retractable door can be set along the entire length of the platform.

[0049] Its drive can be a motor that drives the sliding door through a transmission belt, or it can be designed to have a motor drive the sliding door through a screw.
