Technical Field
[0001] The utility model relates to the technical field of safety doors, in particular to a safety door for subways and high-speed railways. Background Art
[0002] Safety doors, commonly known as "shield doors" or "platform screen doors", are devices installed at the edge of subway and high-speed rail platforms to isolate the platform waiting area from the track area where trains travel. The main function of safety doors is to improve waiting safety, prevent passengers from falling onto the track due to crowding or other reasons, avoid the potential danger of passengers being blown and sucked by the train piston wind, and prevent unrelated staff from entering the tunnel. Safety doors include sliding doors, fixed doors, emergency doors and end doors. Sliding doors are the most commonly used doors for passengers. They correspond to train doors one by one. After the train enters the station and stops, the safety doors will open at the same time as the train doors, and passengers will get on and off the train, and then close at the same time;
[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN218844102U discloses a subway safety door, including a frame, a through slot is provided on one side of the frame, a slide slot 1 is provided in the through slot, two safety doors are slidably sleeved in the slide slot 1, and a safety mechanism is provided on one side of the safety door. A slide slot 2 is provided at the upper end of the slide slot 1, and two sliders are slidably provided in the slide slot 2, and the slider is fixedly connected to the safety door. A double-axis motor is embedded in the frame, and the threaded rod is rotated by the operation of the double-axis motor, so that the slider moves and drives the safety door to open. The through slot is convenient for passengers to pass through, and the safety door and safety mechanism are provided to protect the passengers waiting for the subway, and the passengers' standing positions are dispersed on both sides of the safety door through the safety mechanism to avoid crowding on and off the train caused by the dispersed standing positions of the personnel, thereby improving the riding efficiency.
[0004] Since the safety door has a large area and the cleaning speed of the cleaning staff is slow, the cleaning staff needs to spend a lot of time cleaning, which increases the cleaning cost of the high-speed rail safety door. For this reason, we propose a safety door for subway and high-speed rail to solve the above problems. Utility Model Content
