  • Publication number: 20250051142
    Abstract: A passenger conveyor system and an anti-collision device for step and comb plate. The passenger conveyor system includes a step chain having a plurality of steps, a comb plate and an anti-collision device, the anti-collision device includes an actuating mechanism connected to the comb plate and configured to, when a moving distance of a step adjacent to comb teeth of the comb plate to be engaged in a vertical upward direction of the passenger conveyor system exceeds a preset value, actuate the comb plate to be lifted up from an initial first position to a second position to avoid collision with the step; and a reset mechanism configured to return the comb plate from the second position to the first position after the step travels through the comb plate.

  • Publication number: 20250033934
    Abstract: A brake system for a conveyor system. The brake system includes a brake, a distance detection device and a controller. The brake includes a brake arm and a brake lining connected to the brake arm. The distance detection device is arranged on the brake for detecting a first distance and a second distance between the brake arm and a brake drum, where the first distance is a distance between the brake arm and the brake drum when the brake is in an open state, and the second distance is a distance between the brake arm and the brake drum when the brake is in a closed state. The controller is used for determining a brake performance of the brake based on a difference between the first distance and the second distance detected sequentially, and for generating and sending warning signals when the difference is not within a preset range.

  • Patent number: 10703609
    Abstract: A passenger conveying device, including: an entrance, an exit, and a plurality of steps disposed between the entrance and the exit. A skirt guard panel is respectively disposed on two sides of the step, and the step is constructed to reciprocally move between the entrance and the exit along a path defined by the skirt guard panel. The step includes a tread, a tread guard panel is attached to each of two sides of tread, and the tread guard panel is located between the tread and the skirt guard panel. The tread guard panel includes two or more protrusions, each protrusion is constructed to protrude with respect to an upper surface of the tread, and a protrusion farther away from the tread has a larger protrusion height. The passenger conveying device of the present invention has the advantages of simple structure, reliable installation, and convenient maintenance.
