A winch control system for variable diameter cable and its control method

Abstract

The present invention relates to a winch control system for variable-diameter cables, which includes a screw mechanism and a reel mechanism that cooperate to complete the cable unwinding and cable take-up movement, and also includes a control mechanism for controlling the cable retraction process. The control mechanism Collect the rotation angle information and cable diameter information from the screw mechanism and the reel mechanism, obtain and store various parameters of the cable through calculation, and feed back the speed adjustment instructions to the screw mechanism and the reel mechanism at the same time. At the same time, the invention provides a set of Utilizing the control method of the control system, the synchronous control of the lead screw mechanism and the reel mechanism can be realized, and the rewinding and unwinding of the variable-diameter cable can be completed. The invention realizes the cable receiving and unwinding operation of the variable diameter cable through the cable discharge screw and the cable storage drum, and is equipped with an encoder and a control system to automatically measure, calculate and control, with convenient operation and precise control, and can be widely used in various On the winch equipment that needs to retract and release the variable-diameter cable, there will be no problem of cable arrangement confusion at the same time, and the cable can be arranged reasonably according to the change of the cable diameter, and the work is stable and efficient.

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
