Title:
ESCALATOR CHAIN DEFLECTION RANGE CONFIRMATION DEVICE AND DEFLECTION RANGE CONFIRMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/002895
Kind Code:
A1
Abstract:
This deflection range confirmation device for checking the deflection range of an escalator chain comprises a laser projection unit including a reference laser projector that irradiates the side of a chain located in a part to be measured with a reference laser beam from the horizontal direction, and at least one confirmation laser projector that emits a confirmation laser beam parallel to the reference laser beam. The at least one confirmation laser projector is disposed at a position where the irradiation interval between the reference laser beam and the confirmation laser beam becomes a deflection range setting value. A maintenance staff presses the part to be measured with a prescribed force in the pressing direction and checks whether the part to be measured is included in the range between the reference laser beam and the confirmation laser beam.
