Description

Half high-speed railway platform door release mechanism

Technical Field

The invention belongs to the technical field of high-speed railways/intercity railway platform screen doors, and particularly relates to a half-high type high-speed railway platform door unlocking mechanism.

Background

The platform screen door system is a continuous screen which is arranged at the edge of a platform, isolates a passenger waiting area from a train running area, corresponds to a train door, and can open and close a sliding door in a multi-stage control mode, and generally has the characteristics of full height, half height, sealing and non-sealing, and is called a screen door or a platform door for short. When the train arrives and departs, the shielding door can be automatically opened and closed, the driving space and the passenger waiting space are mechanically isolated, and a safe and comfortable waiting environment is created for the passengers.

In the operating environment of high-speed railways and inter-city railways, due to the fact that the train density is high, factors that trains passing through stations (without stopping stations) pass through the stations at high speed and the like can cause a series of aerodynamic problems, and therefore the safety of passengers and workers on the platforms is threatened, and particularly the situation of underground platforms is solved. In the design and construction of part of intercity railways, in order to embody the characteristic of fast forward and fast out of the intercity railways and save the engineering investment, the intercity railways also adopt a platform waiting mode similar to a subway, the potential safety hazard of platform waiting is increased, and a platform door device is necessary to be arranged on the edge of the platform to ensure the safety of passengers and the operation safety.

Traditional subway shield door adopts locking lever up-and-down motion's mode to realize unblanking and close the lock, like prior art, the chinese utility model document of publication number CN203361813U discloses an emergency door latch mechanism for on half high shield door, including fixing base, sliding block unit and swing piece unit, the sliding block unit includes sliding block, check lock lever, prerequisite lift plate and side lift plate, and swing piece unit is including swing piece, shutting trigger lever, location axle and torsional spring. The sliding block unit is controlled to slide up and down through the swinging of the swinging block unit, so that the defects of poor accuracy, high installation requirement and inconvenient maintenance caused by a long connecting rod mechanism in the prior art are avoided. However, the high-speed railway platform door needs more movable doors due to the requirement of adapting to the parking positions of different vehicle doors of various vehicle models, even each movable door arranged along the platform can slide leftwards and/or rightwards, when the movable door reaches a preset position, the movable door needs to be locked with the ground, the shielding door is fixed on the ground by the door lock mechanism, particularly, the front and back staggered half-high-speed railway platform door comprises sliding doors staggered in the front and back, and each sliding door can slide leftwards and rightwards. Because of the two-layer movable door structure, the thickness of the platform door is increased, and in order to better realize space utilization and avoid interference of the moving devices of the front and rear movable doors, the driving transmission devices of all layers of movable doors are required to be arranged below the ground. In summary, no unlocking mechanism suitable for the bottom-driven half-height high-speed rail platform door exists in the prior art.
