Real-time fault diagnosis and early warning device and method for wire rope of coal mine hoist

Abstract

The invention discloses a real-time fault diagnosis and early warning device and a real-time fault diagnosis and early warning method for a wire rope of a coal mine hoist, and belongs to a device and a method for fault diagnosis of the wire rope of the hoist based on on-line monitoring data. A core processing module of the device is simultaneously connected with a data storage module, a program storage module, a liquid crystal and touch screen control module, a data acquisition module, an Ethernet module and an alarm module; and a power module is connected with all the modules to provide power for all the modules. The method comprises the following steps of: calculating loss percentage of the sectional area of the wire rope; transmitting real-time data of the section area of the wire rope into the core processor module through an Ethernet interface; comparing with an initial value of the section area of the wire rope; and outputting in the form of loss percentage of the sectional area of the wire rope. The device and the method have the advantages that safety parameters are set aiming at application places of the wire rope; the application is flexible; the working state of the wire rope can be judged according to the on-line monitoring data; the real-time fault diagnosis and early warning function of the wire rope can be realized; and alarm information is given.

Description

technical field [0001] The invention relates to a hoist wire rope fault diagnosis device and method based on online monitoring data, in particular to a coal mine hoist wire rope real-time fault diagnosis and early warning device and method. Background technique [0002] The wire rope is an important part of the hoist. Once the wire rope breaks, it will lead to a major accident and cause serious personnel and property losses. The steel wire rope wound around the hoist drum, after using for a certain period of time, the surface steel wire rope will gradually break due to fatigue, the friction between the steel wire rope and the drum, pulley, sky wheel and the mutual friction of the steel wire rope itself will cause surface and internal wear, and the corrosion of the steel wire rope will also Weaken its load-bearing area and increase the tensile stress in the rope. In addition, the breaking force of the wire rope decreases with the increase of service time and bending times. ...
