Control system and control method for load cable cleaning and maintaining line

Abstract

The invention discloses a control system and control method for a load cable cleaning and maintaining line. The control system comprises a controller, wherein the input end of the controller is connected with a wire-fracturing detecting device and a tension detecting device, the output end of the controller is connected with a paying-off device, an oil blow-drying device, a water blow-drying device, a high-pressure water cleaning device, a rough brushing device and a taking-up device, and the controller is connected with a water heating device and a temperature control device of an oil heating device through an RS485 bus. Through writing of a macro-program of a touch screen and writing of interior programs of the PLC, temperature parameters and speed parameters of the system can be detected at any time, the touch screen can detect changing of the parameters at the first time, if an abnormal condition occurs, alarming information will be generated, and safety of the system is improved.

Description

technical field [0001] The invention specifically discloses a traction wire rope cleaning and maintenance line control system and control method. Background technique [0002] Steel wire rope is a kind of flexible member widely used in engineering. It is widely used in equipment such as electric power construction, hoisting and freight ropeway. In use, steel wire rope is often the key component of equipment. Therefore, the safety and importance are self-evident, but the traction wire rope passes through a complex environment along the way, and the turnover is frequent, and phenomena such as broken wires, wear, corrosion and even sudden breakage will inevitably occur, and its damage and bearing capacity will directly affect the workers. life safety and the normal order of production. In order to ensure safe production, foreign steel wire rope professional research institutions have formulated corresponding industry safety regulations and national testing standards for the us...

AI Technical Summary

Problems solved by technology

[0003] In China, Henan Power Transmission and Transformation Company, Ningxia Power Transmission and Transformation Company, Hunan Electric Power Company and Shanghai Electric Power EHV Transmission and Transformation Company have researched, developed and applied the wire rope maintenance machine. It has been developed on the Internet, and electric control and maintenance oil recovery devices have been added, which has achieved certain results, but the steel wire rope has not been decontaminated before oiling, and the maintenance effect is poor, and it does not have the functions of pulling force and broken wire detection.

Hunan Electric Power Company connected the wire rope broken wire detection device in series before the wire rope was immersed in oil, and conducted research on the quantitative detection of wire rope broken wire and wear, but the decontamination of the wire rope was not thorough, and it did not have the function of tension detection

Shanghai Electric Power EHV Power Transmission and Transformation Co., Ltd. proposed and developed the whole-process inspection of the steel wire rope maintenance process. The equipment uses a large power, and both the traction and tension parts use rollers, so that the steel wire rope maintenance process bears a large tension and cannot achieve the purpose of maintenance well. , does not have broken wire detection function

After investigation, it was found that most domestic electric power companies focus on the oil-immersed maintenance of steel wire ropes, but did not clean the steel wire ropes thoroughly before oil immersion, so the maintenance effect is not ideal
