Description

Technical Field

[0001] The utility model relates to the technical field of high-speed railway platform doors, and in particular, to an anti-freezing platform door column structure. Background Art

[0002] With urban development, the demand for rail vehicles to provide transportation between cities and suburbs is increasing. With the diverse development trends in various regions, the actual demand for rail vehicles varies greatly. Within-city subways (including underground and above-ground rail transit) and intercity trains (including EMUs, high-speed trains, and conventional trains) are collectively referred to as rail transit vehicles.

[0003] However, the platforms of these rail transit vehicles have a large flow of people and the rail transit runs at a high speed. It is necessary to install a screen door at the platform to separate the platform personnel from the rail vehicles to prevent the platform personnel from accidentally falling onto the platform and causing danger. The current innovative design has a platform door structure with a pull rope setting. A large-opening door body is formed by a longer pull rope, which is suitable for situations where the door opening positions of high-speed rail carriages of various specifications are different. For example, the Chinese patent utility model patent CN219953058U provides an energy-saving rail transit platform door structure, which relates to the field of rail transit technology, including a number of columns and a pull rope set between two adjacent columns, a lifting column is set on the column, a slider for connecting to the pull rope is set on the lifting column, a balance block is set on the column, a drive motor and a drive chain connected to the drive motor are set at the top of the column, one end of the drive chain is connected to the lifting column, and the end of the drive chain away from the lifting column is connected to the balance block; a display screen is set on the column, and the display screen is an ink screen. The above-mentioned utility model utilizes the structure of the pull rope to increase the opening degree of the platform screen door, which can adapt to the opening of different trains while reducing the weight of the platform screen door. When the pull rope is raised or lowered, a balance block is provided to balance the lifting weight. The driving machine can be driven by a smaller power, and an ink screen electronic screen is used to further reduce the power consumption of the entire platform.

[0004] However, high-speed rail platforms are generally designed in open fields and are greatly affected by temperature fluctuations, especially in northern regions with long winters and extremely low temperatures. Once it rains or snows, the platform doors are easily frozen. High-speed rail platform doors are currently rarely used, and anti-freeze designs for high-speed rail platform door columns are completely blank in the market. The only reference is the anti-freeze structure of platform doors in subway rail transit. For example, Chinese patent invention CN105986742A discloses a rail transit anti-freeze platform door, whose fixed door is a semi-enclosed box, and the movable door is extended or retracted into the fixed door box by a parallel transmission mechanism to open and close the movable door; heating devices are provided on both the fixed door and the movable door. This effectively insulates the fixed door and the movable door, preventing frost / ice from forming on the movable door and the transmission mechanism, allowing them to operate normally in low-temperature environments. The guide rails are fixed in the fixed door box, and the sliders are fixed to the movable door. Since the guide rails are arranged inside the fixed door box, in a closed space, they have better thermal insulation, which can reduce energy loss while better protecting the guide rails. The guide rails inside the fixed door housing are retractable; when the movable door extends out of the fixed door housing, the guide rails retract. An emergency door can be installed in the blank area of ​​the fixed door housing where there are no guide rails, effectively solving the problem of an emergency door being unable to be installed on the fixed door housing.

[0005] However, the above-mentioned rail transit antifreeze platform door still has the following disadvantages: it can only be used on subway rail transit platforms and cannot be used on high-speed rail platforms, and it cannot effectively prevent freezing of the door columns of the high-speed rail platform door lifting structure, resulting in the high-speed rail door being unable to open and close normally when the high-speed rail enters the station.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient anti-freeze platform door column structure. Utility Model Content
