AI Technical Summary

Problems solved by technology

However, when it comes to escalators with very high steps, the loads applied to the chains are high
Therefore, in some cases, it is impossible to transmit sufficient drive force by relying on only one end of the drive chain

Embodiment Construction

[0028] Embodiments of the present invention will be described with reference to the drawings.

[0029] FIG. 1 is a schematic diagram showing the structure of a passenger conveying system according to a first embodiment of the present invention. As shown in FIG. 1, a passenger conveying system 20 according to a first embodiment of the present invention constitutes an escalator. The passenger conveying system 20 includes a tread rail 4 which is supplied to the frame 120 in a circular manner and has a plurality of treads 2 which move along the tread rail 4 . The footboard guide 4 according to the present invention is constituted by a pair of members, each of which is a C-shaped portion (refer to FIG. 3 ) which opens inwardly.

[0030] A plurality of footboards 2 are connected to each other with a pair of chains 5 (from the plan view of FIG. 1 , the chain 5 on the front side and the chain 5 on the rear side) having Roller 5a. That is, located in the transverse direction of the ...

Abstract

A passenger conveyor device, comprising eccentric crankshafts (8) connected to drivingly rotating devices (6), swing bodies (10) connected to the eccentric crankshafts (8), and pin roller rolling teeth (11) having trochoid tooth profiles provided in the swing bodies (10), wherein, when the swing bodies (11) perform a swing motion according to the eccentric swing of the eccentric crankshafts (8), the trochoid tooth profiles of the pin roller rolling teeth (11) are meshed with pin rollers (5a), and provide a thrust to the pin rollers (5a) to drive steps (2).

Description

technical field [0001] The present invention relates to a passenger conveying system, such as an escalator, a moving sidewalk, etc., and in particular, the present invention relates to a passenger conveying system with a long moving distance. Background technique [0002] As an example of a passenger conveying system, an escalator includes a plurality of treads, and guide rollers are installed at the front and back of each tread. The plurality of treads are supported by means of a tread rail provided in the structure engaging each guide roller of the tread. The footboard moves in a horizontal direction near the beginning of entry and exit while remaining horizontal, and moves in a direction inclined up and down by about 30° between the entry and exit strokes. [0003] Generally, a plurality of treads are connected to each other by chains, and all the treads move synchronously and continuously by driving the chains. [0004] A device used by a drive unit that drives a chain...
