Station platform safety protection screen with integral sliding and multi-stage adjustment and control method thereof

Abstract

The invention relates to a station platform safety protection screen with integral sliding and multi-stage adjustment and a control method thereof. The safety protection screen comprises a limiting slide, a plurality of modular sliding screen units, towing connecting plates and a follow-up adjusting system; the multiple modular sliding screen units are disposed on the limiting slide and can be slid integrally along the limiting slide under the drive of sliding drive devices in the follow-up adjusting system while being subjected to the relative position adjustment, and every two adjacent modular sliding screen units are connected through the towing connecting plates; and the modular sliding screen units are each composed of one intermediate screen, two connecting screens and two end screens with doors. The station platform safety protection screen adopts a modular unit structure, adapts to the protection of different types of trains through integral sliding and multi-stage adjustment,and realizes accurate alignment with a door of a carriage through counting follow-up real-time adjustment, the safety protection screen has a simple structure, convenient production and high controllability, the protective effect is good, and a good riding experience is brought to passengers on the premise of ensuring safety.

Description

technical field [0001] The invention relates to the technical field of platform safety protection, in particular to an overall sliding multi-stage adjustable safety protection screen for a railway platform and a control method thereof. Background technique [0002] my country has a vast territory and a large population. Trains are the main means of transportation across provinces and cities. The time for trains to stop on platforms is generally relatively short. Therefore, the mode of "people waiting for trains" is generally implemented, that is, passengers enter the platform a few minutes in advance to wait for the arrival of the train; At present, there are basically no protective measures between the railway stations and the rails, which may easily lead to some personal accidents, such as crossing the rails forcibly due to the wrong platform, falling onto the rails due to crowding or physical reasons, or causing children to fall due to poor parental supervision. Falling fro...

Problems solved by technology

[0003] The current railway station platforms generally only have safety warning lines, and the platform staff will also blow whistles to remind passengers to pay attention to safety, but these measures can only serve as a warning, not a protective effect

At present, the subway station has basically realized fully enclosed protection, because the subway models are basically the same, and the positioning is accurate when parking, it is convenient to use fixed subway screen doors to isolate the track from the platform; in addition, the subway speed is low, and the atmospheric pressure difference between the car body and the platform Small, the lateral pressure on the subway screen door is small; and the subway line is simple, and the parking time requirement is not high; but for the train, the railway line is distributed in a criss-cross pattern, and many cars share a platform, so the parking time requirement is very accurate. Will affect the itinerary of subsequent trains

[0004] The main reason why the railway platform cannot achieve full shielding protection at present is that there are many types of trains in operation in my country, and the lengths of the carriages are not the same, so it is impossible to use fixed protective devices; at the same time, the train body is generally long and artificial The positioning and parking accuracy is very poor. Even if the positioning of the front of the car is accurate, due to the different lengths of the carriages, the parking position of the rear carriage is more different from the preset position of the platform, and passengers need to run to find the corresponding carriage.

[0005] The Chinese patent with the application number 201410470374.X discloses a "platform safety door suitable for all train models", which installs sliding door components along the entire platform along the length, so that any position on the platform can be a door opening area, so as to accommodate The door opening position of the train door of all models; although it can theoretically open the door at any position, but because the position of each door is fixed, it cannot be guaranteed that the door opening area is aligned with the position of the carriage door. If there is a deviation, the door frame will be in In the open area of ​​the carriage door, it will affect the flow of people getting on and off the train, and even lead to congestion, stampede accidents or the embarrassment of large portable boxes getting stuck and unable to be removed

In addition, the door opening position can only be determined after the train stops, and the corresponding sliding door must be opened through manual observation and operation, which will inevitably affect the speed of door opening and involve too much manpower and time

[0006] The Chinese patent with the application number 201710963957.X discloses "a kind of telescopic platform screen door". When two sets of telescopic doors are opened and combined, the net opening of the sliding door can be doubled, which solves the problem of the fixed door of the existing platform screen door. When the size is limited, it is impossible to arrange and multiply the problem of increasing the net opening of the sliding door

However, increasing the net opening of the sliding door also makes the areas on both sides of the compartment door lose protection, so it is not the best way to solve the problem

[0007] In addition, the current platform shielding device mostly adopts a double-rail structure with overlapping inner and outer doors. The double-rails are either installed on the ground in parallel, or installed one above the other. The structure is relatively complicated, which is not conducive to installation.

The platform shielding device generally adopts the structural form of fixed body and sliding door body, and most of them are equipped with fixed door frames. The adjustment range is small, and it is difficult to truly meet the protection needs of various types of trains.
