Winch control system for variable diameter cables and control method thereof

Abstract

The invention relates to a winch control system for variable diameter cables. The winch control system comprises a lead screw mechanism and a winding drum mechanism which cooperate to complete cable unwinding and winding motions; and the winch control system further comprises a control mechanism for controlling the winding and unwinding process of the cables, wherein the control mechanism collectsrotation angle information and cable diameter information from the lead screw mechanism and the winding drum mechanism, and the control mechanism obtains and stores various parameters of the cables through calculation and meanwhile gives feedback on a rotating speed adjusting instruction to the lead screw mechanism and the winding drum mechanism. The invention further provides a control method using the control system, and according to the control method, synchronous control over the lead screw mechanism and the winding drum mechanism can be achieved, and winding and unwinding of the variablediameter cables are completed. According to the winch control system for the variable diameter cables and the control method thereof, winding and unwinding operation of the variable diameter cables can be realized through a cable arranging lead screw and a cable storing winding drum, and supported encoders and a control system are arranged to realize automatic measurement, calculation and control, so that operation is convenient, control is accurate, and therefore the control system and method can be widely applied to various winch devices requiring winding and unwinding of variable diametercables; and meanwhile, the problem of disordered cable arrangement is avoided, namely the cables can be reasonably arranged according to cable diameter changes, and accordingly stable and efficient operation can be realized.

Description

technical field [0001] The invention relates to the technical field of winch control, in particular to a winch control system and a control method for variable-diameter cables. Background technique [0002] The winch is widely used in industrial hoisting, ship towing, deep-sea salvage, deep-sea exploration and other occasions. Its main function is to realize cable laying and take-up. Especially in the process of take-up, the cables need to be neatly arranged on the cable storage drum through the screw. This just requires that the cable discharge screw maintains a certain synchronous relationship with the rollers and the cable storage reel. For winches used in the marine field for active cable discharge, the cable discharge screw and the cable storage drum are generally driven by independent motors, so the synchronous control between the lead screw motor and the drum motor is very critical during the winch cable winding process. At present, the common winches can only perfor...

AI Technical Summary

Problems solved by technology

At present, the common winches can only perform synchronous cable discharge control on cables with fixed diameters. This kind of winch has two key defects: first, when the winch replaces the cables, the operator needs to manually configure the diameter parameters of the cables to be replaced. In the winch control system, for some unmarked cables, the operator needs to accurately measure the diameter on site, resulting in a cumbersome process of replacing the cables and a low level of intelligence; The special cable (i.e. variable diameter cable), at this time, when the traditional winch is used to arrange such cables, there will be a problem of cable confusion
