Time-History Study on Tension of Steel Wire Rope in Multi-Rope Friction Hoisting System
Multi-rope friction hoist is the only hub connecting the underground and the ground,and it is very important to ensure its safety.However,there is little research on the tension of multi-rope friction wire rope.Taking the wire rope in the hoisting system as the research object,the tension formula of wire rope in the existing literature is improved.The experimental value of wire rope tension is obtained through field measurement,and the improved formula is numerically simulated and compared with the experimental value and the formula before improvement.Finally,the dynamic response of the derrick structure is analyzed when the container is fully loaded.The results show that the maximum tension difference between the theoretical value and the experimental value calculated by the improved wire rope tension formula in this paper is 7.637 6%,and the maximum tension difference between the improved formula and the original formula is 0.070 3%,which is in good agreement.The amplitude of the loading point in the horizontal X and vertical Y directions at the moment of operation of the hoisting system increases rapidly to the peak value and then drops sharply,and then gradually tends to be flat.
