Electric control winch control system and control method thereof

Abstract

The invention relates to an electric control winch control system. The electric control winch control system comprises a PLC, a base, a motor, a speed reducer and a winding drum, wherein the motor, the speed reducer and the winding drum are arranged on the base, the winding drum comprises a winding drum body and two winding drum hubs arranged on the left side and the right side of the winding drumbody respectively, a steel wire rope is wound around the winding drum body, a main shaft of the motor is connected with an input shaft of the speed reducer, the PLC is electrically connected with themotor, an output shaft of the speed reducer is connected with the winding drum, the control system further comprises a limiting mechanism which is arranged above the winding drum and is used for limiting the steel wire rope, a shaft sleeve type rotary encoder which is arranged on the output shaft of the speed reducer in a sleeving manner, a travel switch device which is arranged below the windingdrum and a high-precision electric lifting platform which is used for controlling the travel switch device to ascend and descend, and the shaft sleeve type rotary encoder, the travel switch device and the high-precision electric lifting platform are electrically connected with the PLC. The electric control winch control system can intelligently detect overlapping and knotting of the steel wire rope on the winding drum of a winch, timely control the winch to stop and prevent the steel wire rope from going out of the winding drum.

Description

technical field [0001] The invention relates to the technical field of hoisting machines, in particular to an electronically controlled hoisting machine control system and a control method thereof. Background technique [0002] The hoist is a light and small lifting device that uses a drum to wind a wire rope to lift or pull heavy objects. At present, the most common is the electric control (electric) winch, such as figure 1 As shown, the hoist generally consists of a base 1, a PLC controller 6 (not shown) and a motor 2, a reducer 3, and a reel 4 arranged on the base 1, and the reel 4 includes a reel body 41 and is respectively arranged on The reel hub 42 and the reel hub 43 on the left and right sides of the reel body 41, the reel body 41 is wound with a steel wire rope 5, and the main shaft of the motor 2 is connected to the input shaft of the reducer 3 (not shown in the figure, the connection technical means It is a conventional technical means in the art), the input sh...

AI Technical Summary

Problems solved by technology

The wire ropes 5 on the reel 4 should be neatly arranged, and the wire rope 5 is wound on the reel 4 for one layer, and then the next layer; This will cause the steel wire rope 5 to overlap and knot, which is not conducive to the safe use of the steel wire rope 5

[0003] In the actual use process, when the steel wire rope is not stressed for a moment (the end of the steel wire rope pulling the heavy object is unloading the heavy object), it will loosen due to the elasticity of the steel wire rope, causing the steel wire rope to overlap, knot or go out of the drum. The continuous use of the wire rope in the case of overlapping, knotting or going out of the drum will easily lead to the accident of wire rope breaking
