Method and device for detecting abrasion of guide shoe of sliding door

Abstract

The invention relates to a method for detecting abrasion of a guide shoe of a sliding door. The method comprises the following steps that S1, an inclination angle sensor installed on the sliding door is adopted to detect the inclination angle of the sliding door relative to the vertical axis; S2, the abrasion thickness of the guide shoe is calculated based on the inclination angle and the height of the sliding door; and S3, the abrasion state of the guide shoe is judged based on the abrasion thickness and the abrasion threshold value. The invention further relates to a device for detecting abrasion of the guide shoe of the sliding door. According to the sliding door guide shoe abrasion detection method and device, the inclination angle sensor is ingeniously arranged to automatically collect the inclination angle of the sliding door relative to the vertical axis, so that the abrasion thickness of the guide shoe is calculated, the abrasion thickness is compared with the abrasion threshold value, and the abrasion state of the sliding door guide shoe is automatically and indirectly measured; the device has the characteristics of high automation degree, high detection efficiency, good quality and strong reliability, and is very ingenious in conception, simple and convenient in operation process and easy to implement.

Description

technical field [0001] The invention relates to the field of sliding doors, in particular to a method and device for detecting wear of guide shoes of sliding doors. Background technique [0002] Due to the rapid growth of urbanization, the demand for rail transportation is also increasing, and the application of platform screen doors is becoming more and more extensive. Screen doors usually use sliding doors, and the most severely worn parts in the specific process are sliding door guide shoes. When the sliding door guide shoe is worn to a certain extent, it must be replaced, otherwise it is easy to cause failures such as poor operation of the sliding door or even jamming. However, since the sliding door guide shoe is located under the sill, it is easy to block the line of sight, which is not conducive to the detection of conventional vision and detection tools, so there are certain potential safety hazards. [0003] In the prior art, there is no special detection scheme f...

AI Technical Summary

Problems solved by technology

Therefore, the above-mentioned solution will have the following problems in practical application: 1. The blindness is high, and the wear degree of the guide shoe cannot be accurately predicted; 2. It needs to stop the machine and disassemble the threshold for detection, which is time-consuming and laborious; 3. It cannot be tested in batches and maintained. High cost and low efficiency
