Abstract

This utility model relates to the field of rail transit equipment technology, and in particular to a protective device for rail transit operation and maintenance. It includes two track rail guardrails, a platform screen door, a protective plate, a protective cover, a slider, and a linear drive component. The protective plate is located at one end of the track guardrail and is connected to the linear drive component inside the protective cover via the slider, allowing it to slide along the length of the track guardrail. The protective cover also includes a baffle and an elastic reset component to seal the clearance holes for the slider's movement. The protective plate stably isolates hazardous areas, the protective cover inside the drive component reduces corrosion, the baffle and elastic reset component enhance sealing, and the motor drive enables automatic opening and closing of the protective plate. The overall structure has strong adaptability, improving the safety and efficiency of operation and maintenance, and extending the service life of the equipment.
