The present invention relates to the field of passenger conveyor technologies, and provides a speed detection system of a passenger conveyor and a speed detection method thereof. In the speed detection system and the speed detection method of the present invention, an imaging sensor and/or a depth sensing sensor are/is used to sense at least one part of the passenger conveyor to acquire sequence frames, and the sequence frames are analyzed by a processing apparatus to obtain at least speed information about steps of the passenger conveyor.

Speed detection system of passenger conveyor and speed detection method thereof

The present invention relates to step roller monitoring and maintenance personnel monitoring of a passenger conveyor, and belongs to the field of passenger conveyor technologies. In the monitoring system and monitoring method of the present invention, an imaging sensor and/or a depth sensing sensor is used to sense the step roller/maintenance personnel of the passenger conveyor to acquire data frames, and the data frames are analyzed and processed to monitor whether the movement or position of the step roller/activity or position of the maintenance personnel is in a normal state.

Monitoring of step rollers and maintenance mechanics of passenger conveyors

A passenger conveyor includes a first stationary structure and a second stationary structure; a step positioned between the first stationary structure and the second stationary structure, the step has a tread with a tread surface; and a skirt secured to the step between the step and the first stationary structure, the skirt includes an upper tread edge; wherein the upper tread edge extends beyond the tread surface by at least about 10 mm.

Skirt for passenger conveyer

A roller bearing and newel guide assembly () for a newel () in an escalator () has a newel guide (), a roller chain (), and a spring () connected between the roller chain () and the newel guide () to provide tension to the roller chain (). The roller chain () comprises a series of interlinked chain units (). Each chain unit () includes a frame (), at least one roller bearing (), and a pin () for connecting the roller bearing () to the frame (). Each chain unit () has a female connector () and a male connector (), which allow each chain unit () to connect to an adjacent chain unit () to form the roller chain ().

A connection between step flange coversand passenger conveyor framesis adjustable to vary the position of a step flange cover relativeto moving tread platesor a moving skirtin at least two directions. The adjustable connectionpermits the step flange coverto be precisely positioned with respect to the tread platesor the skirtwithout the necessity of using crude adjustment techniques, such as, for example, using shims.

A balustrade assembly includes a decking panel and a skirt panel that are attached to one another and to a balustrade support structure without fasteners. A positioning device included in the balustrade assembly varies the position of the skirt panel relative to moving steps in two directions by pushing against stationary components that are a part of or otherwise connected to a frame of a passenger conveyor. A balustrade support employed in the assembly reduces material and manufacturing costs and is adjustable to vary the height of a balustrade panel and handrails in a passenger conveyor.

Balustrade and deck mounting assembly for a passenger conveyor

Comb plate () for a passenger conveyor () with a conveyor band and a moving flange a number of teeth () arranged on it essentially parallel to one another across the width of the conveyor band, which mesh in use with grooves () provided on the upper surface of the conveyor band characterised by a deflector guard () which is arranged at the lateral edge of the comb plate () and extends a certain height above the upper surface of the comb plate ().
