Embodiment Construction

[0045] specific implementation plan

[0046] In order to facilitate a better understanding of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Please refer to figure 1 , figure 2 and image 3 As shown, the coupling of this device is based on two technologies of industrial high-speed camera and eddy current thermal imaging for comprehensive damage detection of the steel strip 1 to be inspected. The steel strip is mainly divided into two parts: a polyurethane coating layer 13 on the surface of the steel strip and a steel wire rope 14 inside the steel strip. The device includes a steel strip guide wheel assembly, a position detection module 6 , an industrial high-speed camera 3 , infrared thermal imagers 11 and 13 and a high-frequency AC heating system 12 . The following is an introduction to each part:

[0048] The guide wheel assembly, including the front gu...

Abstract

The invention discloses an elevator steel belt damage dynamic quantitative evaluation device and method, the device comprises a guide wheel assembly, a guide wheel keeps moving synchronously with a steel belt, and the position of a detection device is kept unchanged; the machine vision damage detection module is used for quickly acquiring a steel strip surface picture; the eddy current thermal imaging detection module comprises an induction heating coil surrounding the steel belt, two front infrared thermal imagers arranged at the front end of the induction heating coil and two rear infrared thermal imagers arranged at the rear end of the induction heating coil, the front infrared thermal imagers shoot the unheated steel belt, and the rear infrared thermal imagers shoot the unheated steel belt; the rear infrared thermal imager is used for shooting the heated steel belt; the position detection module is used for detecting the movement position information of the steel belt; and the alarm module is used for graded alarm. According to the dynamic detection device and the quantitative evaluation method for the elevator steel belt damage, dynamic damage detection and quantitative evaluation of the damage degree can be carried out on a polyurethane coating layer on the surface of the steel belt and a steel wire rope in the steel belt, and the elevator health condition is monitored.

Description

technical field [0001] The invention provides a dynamic quantitative evaluation device and method for steel belt damage of an elevator, capable of detecting and locating the damage of the polyurethane coating layer on the surface of the steel belt and the steel wire rope inside the steel belt respectively, so as to realize the dynamic and quantitative evaluation of the damage degree of the steel belt. Background technique [0002] Elevator steel belt is a new type of transmission and load-bearing component developed from traditional steel wire ropes. The core of its heavy load is the steel wire ropes that are equally spaced and side by side inside the steel belt. Compared with the traditional elevator steel wire rope, the polyurethane coating on the outside of the steel belt wraps the steel wire rope completely, which not only has the property of insulation, but also protects the inner steel wire rope, reduces the occurrence of corrosion and wear of the inner side-by-side ste...
