Problems solved by technology

[0003] The friction fit between the rubber layer of the handrail driving wheel and the handrail belt causes wear of the rubber layer on the outer peripheral surface of the handrail driving wheel, thereby reducing the diameter of the rubber layer on the outer peripheral surface of the handrail driving wheel This in turn reduces the speed at which the handrail belt runs

Example Embodiment

[0021] figure 2 A detection device 2 for a handrail driving wheel 1 of an escalator or moving walkway according to an embodiment of the present disclosure is shown, wherein the outer circumferential surface of the handrail driving wheel 1 is provided with a rubber layer 3, the rubber layer having A certain thickness, usually not less than 3 mm.

[0022] The detection device 2 includes a roller 4 arranged to maintain a rolling friction fit with the rubber layer 3 provided on the outer circumferential surface of the handrail driving wheel 1, so that the rotation of the handrail driving wheel 1 drives the roller 4 Rotation movement.

[0023] The roller 4 and the handrail driving wheel 1 have the same linear velocity at their contact.

[0024] The detection device 2 further includes a rotation speed sensor 5 for detecting the rotation speed of the roller.

[0025] When the rubber layer 3 is worn, the rotation speed sensor 5 can detect the change in the rotation speed of the roller.

Abstract

The invention discloses a detecting device for a handrail driving wheel of an escalator or a moving walk. Annular grooves or figures are formed in a rubber layer arranged on the outer circumferential surface of the handrail driving wheel.

Description

technical field [0001] The disclosure relates to a detection device, in particular to a detection device for a handrail driving wheel of an escalator or a moving walk. The detection device can realize the detection of the abrasion of the rubber layer of the driving wheel of the handrail, so that maintenance personnel can be notified in time to perform safe maintenance operations. Background technique [0002] In the field of escalators or moving walks, the handrail belt held by pedestrians is driven by the handrail drive wheel (see figure 1 ). Generally speaking, a rubber layer is provided on the outer peripheral surface of the handrail drive wheel to form a friction fit with the handrail belt made of rubber material. For safety reasons, the handrail belt should always run at the same speed as or faster than the running speed of the escalator steps. [0003] The friction fit between the rubber layer of the handrail driving wheel and the handrail belt causes wear of the ru...
