Automatic escalator stair levelness online monitoring method

Abstract

The invention relates to the technical field of escalator safety detection, in particular to an automatic escalator step levelness online monitoring method. The left side and right side of the front end of a step are provided with a left groove and a right groove correspondingly, wherein the left groove is matched with a left extending section, and the right groove is matched with a right extending section. A plurality of photoelectric switches are arranged on one side, close to the step, of an apron board along a running track of the step, so that when the step is in a horizontal state, the photoelectric switches cannot reach a reflecting layer by means of irradiation, and then a reflecting signal is obtained; and when the step is in a left-right inclined state, the photoelectric switches can reach the reflecting layer by means of irradiation, and then a reflecting signal is obtained. By means of the automatic escalator step levelness online monitoring method, the inclination detection of the step of an escalator can be realized without depending on experience and skill levels of detection and maintenance personnel, detection can be carried out without shutdown, and much convenience is brought.

Description

technical field [0001] The invention relates to the technical field of escalator safety detection, in particular to an online monitoring method for the levelness of escalator steps. Background technique [0002] A step is a component that circulates on the escalator truss for passengers to stand on. Usually, the main wheel and the auxiliary wheel are installed on the front and back of the two sides of the step. Time contact and friction, and the need to bear the weight of passengers, so the surface of the main wheel and auxiliary wheels will be worn, and because the passengers do not stand on both sides of the steps in a balanced manner, resulting in the main wheels and auxiliary wheels on the left and right sides of the steps. The different forces on the auxiliary wheels lead to different degrees of wear, which causes the steps to tilt, posing safety hazards. However, the current cascade levelness detection is all realized by shutting down and manual inspection. The inspec...

[0002] A step is a component that circulates on the escalator truss for passengers to stand on. Usually, the main wheel and the auxiliary wheel are installed on the front and back of the two sides of the step. Time contact and friction, and the need to bear the weight of passengers, so the surface of the main wheel and auxiliary wheels will be worn, and because the passengers do not stand on both sides of the steps in a balanced manner, resulting in the main wheels and auxiliary wheels on the left and right sides of the steps. Different forces on the auxiliary wheels lead to different degrees of wear, resulting in step tilting and potential safety hazards

However, the current cascade levelness inspection is realized by manual inspection after shutdown. The inspection process depends on the experience level of the inspectors, and requires regular shutdown for security checks, which is relatively cumbersome.
