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
[0004] In the prior art, the surface of the rubber layer on the driving wheel of the handrail used in the escalator can be smooth without any patterns. The method of identifying the amount of wear is to use a ruler to measure the thickness of the rubber layer on site. Due to the limitation of mechanical space, it is necessary to first It takes time and effort to remove the handrail drive wheel for measurement and then install it back

Embodiment Construction

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

[0022] The detection device 2 includes a roller 4, which is 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 has the same linear velocity as the handrail drive wheel 1 at their contact.

[0024] The detection device 2 also 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 of the rotation speed of the ro...

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...
