Description

Technical Field

[0001] This invention belongs to the technical field of high-speed railway / intercity railway platform doors, specifically relating to a nested high-speed railway platform door and its installation method. Background Technology

[0002] Platform screen doors are devices installed on platforms in railway stations, subways, and other transportation hubs to separate passengers from trains and ensure passenger safety. Platform screen doors include full-height and half-height doors. For high-speed railways and intercity railways, where various train types need to stop, existing platform screen doors generally use conventional designs. These doors are often too large and long, resulting in excessive load, easy damage, and an inability to meet the requirements for opening time and kinetic energy for large opening distances. To improve the compatibility between platform screen doors and train types, the length of the movable door is usually increased, thereby increasing the opening distance. This solution typically uses large-opening platform screen doors.

[0003] However, existing wide-opening platform screen doors increase the length of the sliding doors, thus increasing the opening width and consequently the length of space obstructed by the sliding doors when open. This necessitates the design of fixed doors to match the opening width, and also makes wide-opening platform screen doors unsuitable for train models with shorter door spacing. To address these issues, double-layered stacked platform screen doors utilize a spatial stacking principle, transforming the original wide-opening sliding doors into smaller, foldable door panels. When the main door is open, the smaller panels stack together, maintaining the overall opening width while occupying only half the obstruction space of the large-opening platform screen door, significantly reducing the width of the fixed doors. This allows stacked platform screen doors to accommodate more sliding doors in a shorter space when used with high-speed trains, enabling them to support a wider range of high-speed train models compared to wide-opening platform screen doors.

[0004] Currently, the stacked high-speed railway platform doors are mostly arranged evenly. This arrangement can only accommodate one or two types of high-speed trains and cannot adapt to more types of trains. At present, it is the norm for multiple types of trains to stop at the same platform in my country. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a nested high-speed railway platform door and its installation method, which is applicable to various train models and meets the condition of opening the door at any position.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A method for installing nested high-speed railway platform doors, characterized by the following steps:

[0008] S1: Obtain platform data and train data;

[0009] S2: Based on the acquired platform and train data, construct 3D models of the train and platform through 3D modeling;

[0010] S3: Based on the constructed 3D models of the train and platform, the train doors are projected onto the platform through projection calculations, generating a door-platform projection model and automatically outputting a list of door projections Td0~Td n ;

[0011] S4: Merge the door projections in the door projection list to obtain a new door projection list Td0~Td m (m≤n);

[0012] S5: Based on the new door projection list Td0~Td m (m≤n), formulate a nested platform screen door layout strategy.

[0013] Furthermore, the platform data includes the total length of the platform, the location of the parking sign installation, the opening degree of the platform door, and the type of platform door layout;

[0014] Train data includes the total length of the train, the position of each door from the front of the train, the width of each door, and the train's stopping alignment.

[0015] Furthermore, S3 specifically refers to:

[0016] Assuming the train is stopped at the station facing the track area with its front end on the left side of the platform, calculate the distance d from the left side of the i-th door of the train to the front end. i L, and arrange them in ascending order to obtain the list of car door projections, including the following steps:

[0017] S31: The distance between the i-th door and the front of the train is determined by calculation. The specific calculation formula is as follows:

[0018] d i R = d i L+d i W;

[0019] Where, d i L is the distance from the left side of the i-th door of the train to the front of the train, and d i W is the width of the i-th door of the train, d i R is the distance from the right side of the i-th door of the train to the front of the train;

[0020] S32: By calculation, the train door is projected onto the platform. The specific calculation formula is as follows:

[0021] d t L′=B0+d i L-DB0

[0022] d i R′=d i L′+d i W

[0023] Where, d i L′ is the distance from the left side of the i-th train door to the end of the platform, d i R′ is the distance from the right side of the i-th train door to the end of the platform, B0 is the distance from the stop marker to the end of the platform, and DB0 is the train's stop marker position.

[0024] Similarly, all doors of each vehicle type are projected onto the platform using door projection calculations.

[0025] S33: Project all car doors according to d i Arrange L in ascending order to obtain the projected train doors Td0~Td for each train model. n .

[0026] Furthermore, S4 specifically includes the following steps:

[0027] S41: Based on the preset threshold corresponding to the platform screen door layout type, Td i With Td i+1 Combined into one door (Td) i );Td i With Td i+1 spacing dw i The specific calculation formula is as follows:

[0028] dw i =Td i+1 L-Td i R(0<i≤n)

[0029] kd = 4 × BDW

[0030] Where kd is the door opening width; when the door opening strategy is a nested double door, the corresponding preset threshold is dw. i <BDW; dw i For Td i With Td i+1 The spacing, BDW is the width of a standard movable door;

[0031] S42: Keeping the distance between the left side of the projected car door i and the end of the platform unchanged, calculate the width of the projected car door i to obtain the merged new car door projection list Td0~Td m (m≤n).

[0032] Furthermore, S42 specifically includes the following steps:

[0033] S421: By comparing the distance from the right side of the i-th door to the end of the platform with the distance from the right side of the (i+1)-th door to the end of the platform, the projections of the i-th and (i+1)-th doors are merged using the largest distance. The specific formula is as follows:

[0034]

[0035] Among them, Td i L′ is the distance from the left side of the projection door i to the end of the platform, and Td i R′ is the distance from the right side of the projection door i to the end of the platform;

[0036] S422: Calculate the width of the projected door i after merging, and obtain the new list of door projections Td0~Td after merging. m (m≤n), the specific calculation formula is as follows:

[0037] Td i W′=Td i R′-Td i L′

[0038] Among them, Td i W′ represents the width of the projected car door i.

[0039] Furthermore, S5 specifically includes:

[0040] FIX i LL = ASD i L-BDW

[0041] FIX i LR=ASD i L+4×BDW

[0042]

[0043] Among them, ASD i L represents the installation position of the i-th segment of the movable door. Each segment consists of 4 movable doors, and the width of each movable door is BDW, FIG. i LL represents the installation position of the left-side fixed door corresponding to the i-th segment of the movable door, and FIX represents the position of the fixed door. i LR represents the installation position of the right-side fixed door corresponding to the i-th segment of the movable door, and Td i R′ represents the distance from the right side of the projected car door i to the end of the platform.

[0044] Obtain the installation position of each movable door segment. When i = 0, the installation position is the right side of the current door projection minus 4 times the standard door width. When i is greater than 0, the installation position is the maximum value of the end position of the previous fixed door segment plus the standard door width and the right side of the current door projection minus 4 times the standard door width.

[0046] The beneficial effects of this invention are:

[0047] 1) This invention divides the platform into segments and sets platform doors based on the segmented structure of the platform. This transforms the uncertainty of the corresponding position between the train door and the platform door into the certainty of the relative position between the train door and the platform. This lays a good foundation for the initial determination of the platform door layout. Based on the door stopping position of various train types, the layout planning of the movable doors in the platform doors is further carried out. While ensuring that the doors can be opened for various train types, the number of movable doors is reduced as much as possible. This lays a good foundation for reducing the construction cost of platform doors and standardizing the opening and closing control process of platform doors.

[0048] 2) For the same platform door opening, the width of each movable door in this invention is half that of the large opening method, and the width of the fixed door is halved, which can accommodate more vehicle types. Attached Figure Description
