Modular platform door

Abstract

The invention provides a modular platform door and belongs to the technical field of rail transit. The modular platform door comprises a top box module; a connecting part is mounted at one end of thetop box module; through the connecting part, the top box module is connected with an air duct beam constructed through civil engineering; the other end of the top box module is connected with a portalcrane beam module, wherein a door body module is connected to the portal crane beam module; and one end of the door body module is connected with a bottom base on a civil engineering structure platform. According to the modular platform door, a standardized and modular unit individual is formed, and the two adjacent unit individuals are flexibly connected with each other, and therefore, the problem of a curve station is solved; in addition, as the modular platform door is formed by splicing each module, the workload of field operation is furthest reduced, the mounting quality and the actual effect are improved, the mounting operation management cost is reduced, the problems that materials are supplemented and the construction period is prolonged are solved, and the budget controllabilityof the whole project is enhanced.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a platform door, in particular to a modular platform door. Background technique [0002] On the platforms of high-speed railway stations, intercity train stations, and subway stations, passengers are in danger of falling into the tracks while waiting for the train. In order to prevent this danger, many platforms are now equipped with platform doors. , isolate passengers from the platform door, and ensure the safety of passengers. [0003] However, the existing platform doors are assembled and installed on the spot by distributing their assembled parts and parts body to the scene, and there are several problems in this assembly method: one, due to the parts, parts The number of parts is large, which is prone to loss or missing installation, which is not convenient for system management, and when parts are lost and need to be replenished, it is easy to prolong the assembly peri...

AI Technical Summary

Problems solved by technology

[0003] However, the existing platform doors are assembled and installed on the spot by distributing their assembled parts and parts body to the scene, and there are the following problems in such an assembly method: one, due to the parts, parts There are a large number of parts, which are prone to loss or missing installation, which is not convenient for system management, and when parts are lost and need to be replenished, it is easy to prolong the assembly period; secondly, due to the number of spare parts and parts Many, the installation steps are relatively complicated, and the skill requirements for installation workers are relatively high. If the number of reworks is increased, the corresponding labor cost will be increased, exceeding the expected cost; third, due to the large area of ​​the fixed door in the platform door, thus The deformation of the platform door at the fixed door is correspondingly larger
