Embodiment Construction

[0014] Hereinafter, the escalator 1 which concerns on embodiment is demonstrated, referring drawings. Such as figure 1 As shown, the escalator 1 is, for example, installed obliquely between the upper and lower floors of a building, so that a plurality of steps 3 and handrails 5 are driven synchronously with each other.

[0015] The plurality of steps 3 are connected to each other by an endless chain 7 and circulated by a driving sprocket 9 and a driven sprocket 11 .

[0016] Such as image 3 As shown, the handrail belt 5 is configured to circulate along the outer circumference of the inner panel 6, and to circulate on the circulation path 13, and the circulation path 13 includes an upper movement path 13a, a lower movement path 13b, and an upper movement path 13a. Between the lower moving path 13b and the lower side inversion part 13c which inverts from the upper side to the lower side, and the upper side inversion part 13d which inverts from the lower side to the upper side...

Abstract

The invention relates to an escalator capable of detecting abnormal omen of a hand strap. The escalator is provided with: a hand strap that circulates over an upper movement path and a lower movementpath; a dust measuring device which is provided in the lower movement path and measures the amount of dust in the space; and an abnormality omen detection unit that receives the dust amount signal measured by the dust measurement device. The abnormality omen detection unit transmits an abnormality warning detection signal when the received dust amount signal is greater than a predetermined threshold value.

Description

[0001] This application is based on Japanese patent application 2019-099612 (filing date: May 28, 2019) and enjoys the priority of this application. This application incorporates the entire content of this application by referring to this application. technical field [0002] Embodiments of the present invention relate to an escalator. Background technique [0003] For handrails of escalators, it is known that abnormalities such as the circulation speed are detected. [0004] However, when an abnormality occurs in the driving state of the handrail, when the abnormality is detected, damage or failure due to the abnormality that has occurred may be unavoidable. [0005] On the other hand, it is desired to avoid damage and failure due to abnormality by detecting a sign of the abnormality before it occurs. Contents of the invention [0006] Therefore, the object of this embodiment is to provide the escalator which can detect the sign of abnormality of a handrail. [0007] T...
