Problems solved by technology

[0002] Alignment of escalator handrail pulleys can be a manually intensive and inaccurate process
Additionally, aligning the pulleys can adversely affect other escalator components that may have become affected by the misaligned pulleys
[0003] Additionally or as an alternative, an escalator handrail running off the drive pulley can be hazardous and this can also increase the noise and vibration of the escalator operation, damage the drive system and affect the safety of escalator passengers

Embodiment Construction

[0033] The systems disclosed herein include conveyor systems that move passengers between floors and / or along individual floors. Such conveyance systems may include escalators, people movers, and the like.

[0034] go to figure 1 , an escalator system 200 is disclosed. System 200 may include first member 210, which is a first fixation member. System 200 may further include a first belt 220 that is a handrail and a first assembly 230 that may be a handrail drive assembly. The first assembly 230 may be operatively connected to the first member 210 and the first belt 220 . The first assembly 230 may include a plurality of pulleys, generally referenced 240 , including a first pulley 240A. A plurality of pulleys 240 may be mounted near the first member 210 for driving the first belt 220 . Accompanying the plurality of pulleys 240 may be a corresponding plurality of sensors, generally referenced 250 , including a first sensor 250A.

[0035] go to figure 2 , the plurality of ...

Abstract

Disclosed is an escalator system wherein when a handrail belt is moving from rotation of a plurality of elevator sheaves: a controller receives data from a plurality of sensors, identifies from the data a first sheave of the plurality of sheaves as comprising reference alignment value for the system, determines for the plurality of sheaves a respective plurality of alignment values, compares the plurality of alignment values with the reference alignment value, and provides a predetermined response when any of the plurality of alignment values diverges from the reference alignment value by morethan a predetermined amount.

Description

Background technique [0001] Embodiments herein relate to escalator maintenance, and more specifically, to escalators with Hall effect sensors and magnets configured to detect pulley misalignment. [0002] Alignment of escalator handrail pulleys can be a manually intensive and inaccurate process. Additionally, aligning the pulleys can adversely affect other escalator components that may have become affected by the misaligned pulleys. [0003] Additionally or alternatively, an escalator handrail running off the drive pulley can be hazardous, and this can also increase the noise and vibration of the escalator operation, damage the drive system and affect the safety of escalator passengers. Contents of the invention [0004] According to a first set of embodiments, an escalator system is disclosed comprising: a first member, a first belt, a first assembly operatively connected to said first member and said first belt, said The first assembly includes a plurality of pulleys mou...
