Abstract

The invention discloses an online health prediction method of an elevator composite steel strip. The method comprises the following steps of collecting running parameters of the elevator composite steel strip and constructing a running parameter set; sectioning the composite steel strip according to installation parameters and service building parameters of an elevator; determining loading frequency and the loading type corresponding to each section of the composite steel strip according to the running parameter set; predicting damage condition of each section of the composite steel strip andresistance change condition of embedded steel wire ropes in the composite steel strip by utilizing a fretting wear model; determining an optimal health prediction result compared with the running parameter set by utilizing an error minimum principle; and outputting the health prediction result of the composite steel strip. According to the technical scheme, online automatic health monitoring and safety early warning of the composite steel strip are realized through the method, the hardware cost is low, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of elevator systems, in particular to an online health prediction method for an elevator composite steel belt and an online health prediction device for an elevator composite steel belt. Background technique [0002] An elevator is a fixed lifting device that serves a specific floor in a building. The straight elevator is usually used on a higher floor. The straight elevator system usually includes a car, a counterweight, a driving device, a control system and a load-bearing component. The safety strength of the bearing part is an important indicator to ensure the safety of the elevator system. Traditionally, steel wire ropes are used as the bearing part. An other type of load-bearing component has recently been introduced, an example being a composite steel belt consisting of multiple steel wire ropes enclosed in a polyurethane sheath. The use of composite steel belt has the advantages of energy saving, we...
