Crane and superlift winch rope coiling control system thereof

Abstract

The invention discloses a crane and a superlift winch rope coiling control system thereof. The control system comprises a rope stopper which is arranged on a superlift winch, wherein the rope stopper is movably connected to the rope stopper; and the control system also comprises a driving part which drives the rope stopper to move from the outer side to the inner side of the winch. According to the superlift winch rope coiling control system, the rope stopper can move from the outer side to the inner side of the winch, and when the working conditions of the superlift device are changed, the driving part can be controlled to drive the rope stopper to slide; and moreover, the driving force of the driving part is controlled to change the acting force of the rope stopper on the steel wire rope, so that the rope stopper can apply the acting force through which the steel wire rope can smoothly enter a rope groove to the steel wire rope at any proper position, and the rope is neatly coiled. Therefore, the control system can adjust the position and acting force of the rope stopper along with the working conditions of the superlift device, so that the phenomenon that the rope is climbed and disordered when the rope is coiled through the superlift winch is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a crane and a control system for super-lifting winch and rope collection thereof. Background technique [0002] Cranes, especially super-large tonnage all-terrain cranes, are generally equipped with super-lifting devices, which can effectively increase the lifting weight of the crane. The reason is that the superlift device can reduce the deflection of the boom, and to a certain extent reduce the side bending of the boom. [0003] Such as figure 1 as shown, figure 1 It is a schematic diagram of the structure of the super-lifting device arranged on the main arm. [0004] The super-lifting device mainly includes a super-lifting bracket, two super-lifting arms 12, a super-lifting winch 14, a super-lifting locking device and the like. Super hoisting 14 is also equipped with a super hoisting motor, and when the hoisting oil port of the super hoisting motor is oiled, ...

AI Technical Summary

Problems solved by technology

[0011] The rope gear 15 is arranged on the outside of the super-lift winch 14, and has a single adjustment function. The above-mentioned aspects a, b, c, and d are constantly changing with the working conditions. The fixed rope gear 15 cannot adapt to this change, so adjust The effect of coiling rope is not ideal;
