Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation facilities, in particular to a subway safety door pedal structure. Background Art

[0002] The subway safety door pedal structure usually refers to a pedal or platform device installed between the subway train car and the platform, which is used to improve the safety of passengers getting on and off the train, especially when there is a gap between the platform and the train. By filling the gap between the platform and the train, passengers can be prevented from accidentally falling or getting stuck. For the entire subway system, this is conducive to the efficient operation of the subway, transporting more passengers per unit time, thereby improving the operating efficiency of the subway. At the same time, the stable pedal structure also provides safer and more comfortable passage conditions for passengers carrying luggage and those with limited mobility.

[0003] The existing subway safety door pedal structure is not convenient for enhancing the cushioning and shock absorption in actual use, and it is difficult to extend the service life of the pedal structure itself.

[0004] A search of existing patents revealed a subway safety door pedal structure (publication number: CN221914257U), comprising a platform and platform screen doors mounted on the platform. Two platform screen doors are hinged with linkage rods on opposite sides of the platform screen doors. A rectangular bar is hinged to the free ends of the two linkage rods. The top surface of the rectangular bar is parallel to the platform surface. A rubber pedal is fixed to the rectangular bar. The top surface of the rubber pedal gradually slopes upward from the end closest to the rectangular bar to the end farther away from the rectangular bar, forming a slope. The highest point of the slope is flush with the floor of the train car. This utility model hinges linkage rods on opposite sides of the two platform screen doors and arranges a rubber pedal between the two linkage rods. When the two platform screen doors are opened, the linkage rods, driven by the movement of the platform screen doors, raise the rubber pedal to compensate for the gap and height difference between the platform and the train car, effectively solving the problem of manually constructing a folding pedal.

[0005] Although the above patent achieves that when the two platform screen doors are opened, the linkage rod can drive the rubber pedal to rise through the movement of the platform screen doors to make up for the gap and height difference between the platform and the car, effectively solving the problem of manual operation to build the folding pedal, it is not convenient to adjust the height of the pedal body, and it is difficult to maintain excellent stability in various complex platform environments.

[0006] Therefore, it is necessary to invent a subway safety door pedal structure to solve the above problems. Utility Model Content

[0017] (3) Beneficial effects

[0018] The utility model provides a subway safety door pedal structure, which has the following beneficial effects:

[0019] 1. The subway safety door pedal structure is equipped with a support component and a lifting component. When in use, the hydraulic column is first started, so that the two ends of the hydraulic column rotate on the surfaces of the fixed bolt and the support bolt, and then the push plate is pushed to expand. At the same time, the drive motor is started to drive the threaded rod to rotate. The threaded rod rotates inside the movable block, driving the movable block to slide and rise on the slide groove in the fixed frame. The positioning blocks on both sides slide in the limit columns to remain stable, so that the height of the pedal body can be automatically adjusted during the opening and closing of the subway safety door, so that the pedal body can be accurately flush and seamlessly connected with the platform floor. This high adaptability enables the pedal body to maintain excellent stability in various complex platform environments.

[0020] 2. The subway safety door pedal structure, through the setting of buffer components and buffer shock-absorbing rubber blocks, when encountering external force impact, such as the collision that may occur when passengers get on and off the train, or the pressure generated when carrying heavy objects across the pedal, the pressure is applied to the buffer shock-absorbing rubber block through the pedal body for buffering and shock absorption. At the same time, the pressure will also squeeze the damping hydraulic rod, causing the damping hydraulic rod to contract under force, and the buffer spring to deform under force to generate elastic force, and push the pedal body in the opposite direction, thereby achieving the effect of enhanced buffering and shock absorption. This not only greatly ensures the safety of passengers and avoids accidents such as slips and falls caused by impact, but also significantly extends the service life of the pedal structure itself, reduces the frequency of maintenance and replacement, and thus reduces operating costs.
