Embodiment

[0041] Please refer to Figure 1 to Figure 3 , the present embodiment provides a crane winch anti-disorder rope control system (hereinafter referred to as the control system 100), the crane winch 30 includes a reel, a wire rope and a hook, and the control system 100 includes a boom detection unit 20 and a controller 10 .

[0042]Wherein, the boom detection unit 20 is used to be arranged on the boom to obtain the boom length information and the boom angle information, and according to the boom length information and the boom angle information, obtain the The wire rope length information and wire rope angle information satisfying the balance relationship between the head and the hook;

[0043] The controller 10 is electrically connected with the boom detection unit 20, and is used to obtain the weight of the wire rope and the tension (F) of the wire rope at the jib head of the crane according to the length information of the wire rope and the angle information of the wire rope;...

Abstract

The invention discloses a control system and method capable of preventing ropes of a winch of a crane from being cluttered and a crane, and relates to the technical field of winches of cranes. The control system capable of preventing the ropes of the winch of the crane from being cluttered comprises a cargo boom detection unit and a controller, and the cargo boom detection unit is used for being arranged on a cargo boom to obtain length information and angle information of the cargo boom, and obtain length information and angle information of steel wire ropes which meet the balance relation ofthe head of cargo boom and a lifting hook. The controller is electrically connected with the cargo boom detection unit and is used for obtaining weight of the steel wire ropes and tension force of the steel wire ropes at the head of the crane according to the length information and angle information of the steel wire ropes, calculating hoisting weight including hook weight according to a torque limiter algorithm, and outputting warning information when the hoisting weight is smaller than the tension force.

Description

technical field [0001] The invention relates to the technical field of crane hoisting, in particular to a crane hoisting anti-rope control system, a control method and a crane. Background technique [0002] The winch system is the hoisting mechanism of the crane. It transmits power by winding the steel wire rope, turning the rotary motion into a linear motion, and completes the lifting, stopping, and lowering of the lifting weight. Usually, during the retracting and unwinding process of the wire rope, the wire rope is required to be evenly wound on the hoisting drum. However, if the hoisting wire rope of the crane is at a large magnification, the empty hook or the hoisting weight may be light, which may cause the weight of the wire rope to be out of balance, and the wire rope cannot be tightened. If you continue to hoist at this time, the rope will appear disorderly Phenomenon. The occurrence of the above-mentioned disordered rope phenomenon may require rearranging the hoi...
