Abstract

A device for detecting abnormality of a step includes a detection shaft member (21), detection sections (23, 24, 25), a cam (26), and a limit switch (27). The detection shaft member (21) has a bar-like shape located below a step (10) in a forward run inside a truss (1) and extending in the direction orthogonal to the advance direction of the step (10) and is rotatable about a rotation shaft extending in the longitudinal direction of the detection shaft member. The detection sections (23, 24, 25) are arranged on the outer surface of the detection shaft member (21) such that their head sectionsextend up to the vicinity of portions at which rollers (14, 15) that are portions of structural members (13) of the step and movably support the step (10) are installed. Further, a cam (26) is coaxially attached to the detection shaft member (21), and an operation section (27a) of the limit switch (27) is in contact with the cam (26).

Description

technical field [0001] The present invention relates to an abnormality detection device capable of detecting an abnormality in which a step of a passenger conveyor such as an escalator or a moving walkway sinks due to damage or falling off of a step roller, and a passenger conveyor having the same. . Background technique [0002] The passenger conveyor has a plurality of steps each having a step roller at both end portions. The steps are connected by an endless chain of steps and circulate within the truss from one landing to another. Guide rails are provided along the moving direction of the step chain, on which the step rollers of the individual steps rotate, thereby guiding the steps. [0003] Due to the life of the step rollers and other reasons, there are cases where the step rollers are damaged during the operation of the passenger conveyor. Such damage to the step rollers is undesirable in terms of safety. Therefore, it is desired that when the step roller is dam...
