Description

Technical Field

[0001] The utility model relates to the technical field of railway platform screen doors, in particular to a telescopic half-height high-speed railway platform door. Background Art

[0002] my country's high-speed rail industry is developing rapidly, and passenger flow is growing day by day, but the sudden increase in passenger flow also brings some safety hazards. Because passengers need to get off the train through the high-speed rail platform, but unlike the safety facilities of subway, sky rail and other urban rail transportation platforms, most of the high-speed rail platforms in China currently do not have a platform door system between the platform area and the track area. Especially during holidays, the passenger flow and train number increase sharply, which greatly increases the difficulty of the station staff's work. It is difficult to ensure the personal safety of passengers (especially children) while waiting for the train on the platform through manual management and prevention during special periods such as the Spring Festival travel rush. There is a risk of accidents such as passengers accidentally falling into the track area. At the same time, when encountering strong winds and bad weather, small luggage items on the platform may also be blown into the track, seriously affecting driving safety and causing property losses to passengers. Therefore, the demand for high-speed rail platform doors came into being, which can effectively isolate the track area from the passenger platform area to avoid accidents.

[0003] At present, most high-speed railway platforms in China ensure the safety of passengers waiting for the train through manual management and prevention by station attendants, and a small number of high-speed railway platforms have also added platform door systems. Futian Station uses a fully enclosed full-height platform door to completely isolate the track area from the platform area, greatly ensuring the safety of passengers waiting for the train, but the construction and subsequent maintenance costs of the full-height platform door are relatively high; Zhengzhou East Station uses ropes to replace large areas of special glass and supporting steel facilities such as door frames, effectively saving construction costs, but there are large gaps between ropes and ropes, and between ropes and platform floors, especially for children and small luggage. There is still a possibility of falling into the track area; Xiaogan East Station uses a semi-height platform door similar to the subway ground station. The limitation of this type of platform door is that it can only be used for one or several types of vehicles with close door opening positions.

[0004] There are many types of high-speed rail vehicles in operation in China, usually CRH1, CRH2, CRH3C, CRH380BL, CRH380A and other models. Since the door spacings of different models of vehicles are inconsistent, the platform doors of a single specification similar to that of the subway cannot meet the needs of high-speed rail platform doors. There will be a problem of mismatch between the opening position and opening degree of the platform doors and the platform positions of different high-speed rail models. Summary of the invention

[0031] like Figure 1 As shown, the bottom of the first telescopic gantry 2 and the second telescopic gantry 4 are both provided with gantry running wheels 7, and the gantry running wheels 7 are slidably installed in the running guide groove 6. By arranging a plurality of gantry running wheels 7 at the bottom of the gantry running wheels 7, the telescopic door can be kept stable and smooth during operation, and the gantry running wheels 7 and the door head running wheels 5 share the running guide groove 6, thereby reducing costs.

[0032] In one embodiment, the length of the running guide groove 6 for guiding the first driving door head 1 and the first telescopic door frame 2 and the running guide groove 6 for guiding the second driving door head 3 and the second telescopic door frame 4 is 2.9m, the width is 0.1m, and the depth is 0.016m, and the running guide grooves 6 on both sides can be arranged independently or connected as a whole.

[0038] like Figure 2 As shown, bolts 12 are embedded in the positions corresponding to the columns 11 on the platform, and the bottom of the columns 11 is connected to the bolts 12. Multiple bolts 12 and an embedded steel plate are embedded in the positions corresponding to each column 11 on the platform, and the tops of the multiple bolts 12 pass through the embedded steel plate and are welded and fixed to the embedded steel plate; a connecting steel plate is fixed to the bottom of the column 11, and holes are provided on the connecting steel plate at the positions corresponding to the bolts 12; when the column 11 is installed, the connecting steel plate is placed on the embedded steel plate, and the tops of the bolts 12 pass through the corresponding holes on the connecting steel plate and are fixed by nuts to ensure the stability of the column 11.

[0039] Most of the current high-speed rail vehicles in my country are 24.5-27m long, and the door spacing of each vehicle is 23.3-25.8m, the door width is 1.5-1.8m, and the maximum difference in door spacing of different models is 2.5m. In this embodiment, the total length of the telescopic door is 6m, the minimum basic opening is 2m, and the maximum opening is 5m. The opening can be adjusted by 0.5m unit opening increments based on the minimum opening of 2m, which solves the problem of deviation between the center line of the door and the center line of the platform door caused by the door spacing of different models, and meets the requirements of various high-speed rail models with a length of 24.5-27m in China.

[0040] In this embodiment, the height of the safety door and the telescopic door is 1.5m, which saves investment and facilitates later maintenance.

[0041] The telescopic half-height high-speed railway platform door of this embodiment can adjust the opening according to the door spacing of different models of vehicles. The specific operation process is as follows:

[0042] 1) Confirm safety

[0043] Confirm through the monitoring system or station attendants that there are no passengers or luggage or other foreign objects invading the track area in the platform area, and that there are no waiting passengers or obstacles interfering with the telescopic door's telescopic deformation and running range. The operation process can only be started after safety is confirmed;

[0044] 2) Door opening preparation

[0045] ① The telescopic door control system obtains the platform location, vehicle type and vehicle formation of the arriving vehicle;

[0046] ②Confirm the distance between the doors of the arriving vehicles;

[0047] ③ Determine the distance deviation between the center line of the vehicle door and the center line of the telescopic door;

[0048] ④Determine the increment of telescopic door opening;

[0049] 3) Parking and opening the door

[0050] After the vehicle has stopped and is ready to open the door, the telescopic door control system issues a command based on the distance deviation between the center line of the vehicle door and the center line of the telescopic door to open the telescopic door, ensuring that the door width is within the opening range to meet the needs of passengers for convenient and safe boarding and alighting. At the same time, consider adding on-site real-time monitoring, alarm and emergency stop devices to ensure emergency stop processing in case of any accident during the door opening process;

[0051] 4) Close the door and start the train

[0052] Based on on-site monitoring and station attendants' joint confirmation that passengers have completed boarding and alighting, the control system receives the door closing command. Once the telescopic door has completed closing and is confirmed to be safe, the train can depart.

[0053] The retractable half-height high-speed rail platform door of this embodiment solves the problem of deviation in the distance between the center line of the door and the center line of the platform door caused by the distance between the doors of different models. It can adapt to the platform door requirements of the main high-speed rail models currently in use in China, and better ensure the safety of passengers and driving during periods of sudden increase in passenger flow such as the Spring Festival.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
