Problems solved by technology

The existing escalator step speed measuring device uses an encoder or a proximity sensor installed on the drive host (motor) to detect the rotation speed and direction of the host to indirectly judge the running speed and direction of the escalator steps, not to directly detect the steps of the escalator Running speed and direction, misjudgment may occur, and the safety level is low

Embodiment Construction

[0028] The present invention provides an escalator step speed measurement protection method and a speed measurement device. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] see Figure 1-5 , the present invention provides an escalator step speed measurement protection method, which mainly includes the following steps:

[0030] A. Signal acquisition: Two proximity sensors 1 for sensitive tooth passing are arranged on one side of the main drive sprocket 90 of the escalator, and the distance between the two proximity sensors in the circumferential direction is greater than the tooth spacing L of the main drive sprocket And less than 1.5 times o...

Abstract

The invention provides a cascade speed measurement protection method for an escalator. The cascade speed measurement protection method for the escalator mainly comprises the following steps: A. signalacquisition; B. overspeed detection; C. nonmanipulated reversal detection in a running direction; and D. starting and stopping for the escalator. A cascade speed measurement device for the escalatorcomprises a base plate fixedly connected with a fixed frame of the escalator, and two proximity sensors arranged on the base plate, wherein the two proximity sensors are aligned with wheel teeth of two main drive chain wheels which are arranged in parallel separately, and the interval between the two proximity sensors in the circumferential direction of the main drive chain wheels is 5 / 4 of the tooth distance of the main drive chain wheels. The cascade speed measurement protection method and speed measurement device for the escalator are capable of realizing direct detection for cascade running speed and direction, thereby increasing the safety level.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to an escalator step speed measurement protection method and a speed measurement device. Background technique [0002] In order to prevent the escalator steps from causing casualties due to overspeed and non-manipulative reversal of the running direction, the escalator generally uses a speed measuring device to monitor the speed and direction of the steps in real time, and stops once overspeed or non-manipulative reversal of the running direction occurs The escalator is running. The existing escalator step speed measuring device uses an encoder or a proximity sensor installed on the drive host (motor) to detect the rotation speed and direction of the host to indirectly judge the running speed and direction of the escalator steps, not to directly detect the steps of the escalator Misjudgment may occur due to the running speed and direction, and the safety level is low.
