Description

Gear-rack driven staggered high-speed railway platform door

Technical Field

The utility model belongs to the technical field of high-speed railway platform doors, and particularly relates to a gear-rack driven staggered high-speed railway platform door.

Background

The platform door system is installed on the edge of the station platform to separate the track area of the train from the waiting area of the platform completely, and has continuous barrier corresponding to the train door and capable of being opened and closed in multistage control, and the continuous barrier is generally divided into full height and half height, and is called the platform door for short. When the train arrives at the station or starts from the station, the platform door can be automatically opened and closed according to the running state of the train, so that the running space and the waiting space of the passengers are mechanically isolated, and a safe and comfortable waiting environment is created for the passengers. Because the high-speed railway running train has a plurality of models, and different models correspond to the influences of factors such as different door positions, the platform door of the existing fixed door opening position is difficult to adapt to the door opening requirements of different models of the high-speed railway.

In the prior art, for example, the Chinese patent document with publication number of CN213109309U, named as a staggered high-speed rail platform door, discloses a platform door structure which is integrally arranged in a staggered arrangement of two layers of adjacent movable doors. The platform door structure takes four movable doors as a unit, the movable doors at two ends in the unit are configured to move more than 1 width of the movable doors towards the center direction of the unit, and the movable doors at the non-two ends are configured to move more than 1 width of the movable doors towards two sides of the movable doors. Although the platform door can meet the requirement of one door opening at any position in the movable door unit, as the train doors of the high-speed railway are generally positioned at two ends of the train carriages, two doors at the joint of two carriages of part of the train are relatively close to each other, the situation that the same movable door unit faces the requirement of two doors can occur (for example, a first area needing to be opened is between a first movable door and a second movable door, a second area needing to be opened is between a third movable door and a fourth movable door, and the clearance between the two door opening areas is larger than the width of 1 movable door and smaller than the width of 2 movable doors); the patent can only meet the requirement of opening the door at any position with the clearance between two adjacent train doors being larger than the width of 2 movable doors, so the patent still has certain limitation. In addition, the movable door mainly relies on the guide block and the guide rail to slide mutually to realize the guide in the movement process, and the guide block and the guide rail are easy to wear in the movement process and possibly cause the phenomenon of jamming in the movement process.
