Aiming at the reason that the tension of wire rope of vertical hoist is unbalanced, the tension balance of each rope should be considered comprehensively in the diameter of rope groove and the displacement of each rope by tension determination method, in order to effectively solve the tension imbalance phenomenon.
Because of the intuitive fault handling of the automatic balance suspension device of the vertical hoist wire rope, only the adjustment description of the situation is carried out here. In the actual operation of the vertical hoist 6 wire Rope suspension length is inconsistent, friction wheel 6 rope groove diameter is not consistent, these two reasons are basically associated with the appearance. 6 Wire Rope length is inconsistent caused by wire rope creep, wire rope and friction gasket force deformation, in the friction arc occurred relative creep.
Vertical hoist wire rope creep accelerates the wear of friction wheel friction liner, so that the diameter of friction wheel becomes smaller, these two factors are complementary, so adjusting the suspension length of 6 wire rope is the key to solve the problem.
First, the determination of tension imbalance
In the course of cage operation, it is not possible to compensate the length of the wire rope to observe the expansion of the cylinder of the automatic balance suspension device.
Second, the consistency of the parameters of the wire rope
In the lifting device of the multi-rope friction vertical hoist, the wire rope should be selected to ensure the consistency of the corresponding parameters including mechanical properties (fatigue strength, tensile strength, flexural strength, elastic modulus) and geometric dimensions (section diameter, unit weight), so as to ensure that the same batch of steel wire rolled out by the same mill is twisted on the same machine. The replacement of the vertical hoist wire rope should be accompanied by the replacement of the same material made of the same performance, the same shape of the friction gasket.
