Description

Technical Field

[0001] The invention belongs to the technical field of rail transit platform doors, and in particular relates to a fully adaptable platform door installed closely against the edge of a platform. Background Art

[0002] The high-speed railway platform door system is a comprehensive intelligent door control system that integrates disciplines such as architecture, materials, electronics, automatic control, and computer networks. The system is installed at the edge of the platform of a rail transit station, forming a continuous barrier between the platform area and the track area that can be opened and closed at multiple levels. When the train arrives and stops correctly at the station, the train door and the platform door open at the same time, making it convenient for passengers to get on and off the train, creating a safe and comfortable waiting environment for passengers.

[0003] Disadvantages of existing high-speed rail platform door technology:

[0004] Since there are many types of trains running on high-speed railways and many types of train combinations (such as single group, multiple group, ascending order, descending order, etc.), the position of the door on the platform after the train stops is uncertain (it may be anywhere within the effective range of the platform). In order to solve this problem, the high-speed railway platform door is currently installed 1.2 meters away from the edge of the platform, forming a passenger channel between the high-speed railway platform door and the train, and passengers get on and off the train through this channel. Since the high-speed railway platform door is installed 1.2 meters away from the edge of the platform, the effective waiting space for passengers on the platform is further compressed; passengers get on and off the train through the 1.2-meter channel between the high-speed railway platform door and the train, which will cause congestion for passengers to get on and off the train and reduce traffic efficiency; since there is a certain gap between the train and the edge of the platform, the congestion of passengers getting on and off the train in the 1.2-meter channel at the edge of the platform will increase the safety risk of passengers stepping on the gap.

[0005] Therefore, how to solve the defects of the above-mentioned prior art has become the direction of efforts of technicians in this field. Summary of the invention

[0006] The object of the present invention is to provide a fully adaptable platform door which is installed close to the edge of the platform and can completely solve the shortcomings of the above-mentioned prior art.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A fully adaptive platform door installed closely against the edge of a platform comprises a bottom beam, first to fourth front sliding doors and first to fourth rear sliding doors, wherein the first and second rear sliding doors are sequentially arranged between the first and second front sliding doors, and the third and fourth rear sliding doors are sequentially arranged between the third and fourth front sliding doors, a front linear guide rail is provided on the front side of the bottom beam, and a rear linear guide rail is provided on the rear side, the bottoms of the first to fourth front sliding doors are slidably matched with the front linear guide rail via a slider, the bottoms of the first to fourth rear sliding doors are slidably matched with the rear linear guide rail via a slider, and the first to fourth front sliding doors and the first to fourth rear sliding doors are individually driven by a bottom walking mechanism.

[0009] Furthermore, the bottom walking mechanism includes a front rack, a rear rack, a drive motor and a gear. The front rack is installed on the front side of the bottom beam, and the rear rack is installed on the rear side. The drive motors are installed correspondingly at the bottom of the first to fourth front sliding doors and the first to fourth rear sliding doors. The drive motor is connected to the gear through a reducer. The gears corresponding to the first to fourth front sliding doors are meshed with the front rack, and the gears corresponding to the first to fourth rear sliding doors are meshed with the rear rack.

[0010] Furthermore, the sliders corresponding to the first to fourth front sliding doors and the first to fourth rear sliding doors are connected to the drag chain via a connecting strip.

[0011] Furthermore, a limiting mechanism is provided on the top of each of the first to fourth front sliding doors.

[0012] Furthermore, the limiting mechanism includes a top cover, a left baffle, a right baffle, a connecting plate and a limiting roller. The left baffle and the right baffle are correspondingly installed on both sides of the top of the first to fourth front sliding doors, and the top cover is installed on the top of the left and right baffles, thereby forming a closed cavity on the top of the first to fourth front sliding doors. Connecting plates are symmetrically arranged on the top surfaces of the first to fourth front sliding doors, and two limiting rollers are installed on the connecting plates, and a space for the first to fourth rear sliding doors to pass through is formed between the two limiting rollers.

[0013] Furthermore, U-shaped side beams are provided at the front and rear sides of the bottom beam respectively, and the bottom of the bottom beam is connected to the U-shaped side beams through a mounting plate, and the mounting plate is fixedly connected to the platform structure beam through a chemical anchor bolt.

[0014] Furthermore, top plates are installed on the tops of the bottom beam and the U-shaped side beams, and there are gaps between adjacent tops.

[0015] Furthermore, each of the first to fourth front sliding doors and the first to fourth rear sliding doors is provided with an installation cavity, and a driving motor is installed in the installation cavity.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. It solves the problem that high-speed railway platform doors cannot be installed close to the edge of the platform. It can realize the opening and closing of platform doors at any position of the effective platform, meeting the opening and closing requirements of all train models and train combination types;

[0018] 2. Increase the efficiency of passengers getting on and off the bus and reduce safety risks;

[0019] 3. Installing this platform door on the existing high-speed railway platform does not require large-scale changes to the platform structure, and the installation is easy and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In this embodiment, a top plate 25 is installed on the top of the bottom beam 1 and the U-shaped side beam 21, and there is a gap between adjacent tops. The existence of the gap is to facilitate the installation of the slider 12 and the gear 16.

[0047] The present invention can open and close the platform door at any position of the effective platform, meeting the door opening and closing requirements of all train models and train combination types, thereby solving the problem that high-speed railway platform doors cannot be installed close to the edge of the platform. The close installation further increases the effective waiting area for passengers on the platform and the efficiency of boarding and alighting, reducing the safety risks of passengers.

[0048] The bottom walking mechanism of the present invention adopts modular components, which are convenient and quick to install and maintain; the existing high-speed railway station does not need to close the station for construction when installing the platform door, and the installation can be carried out at the night parking skylight point without affecting the normal operation of the high-speed railway platform during the day.
