The Analysis of Security Wedge Lock-Rope Mechanism by ANSYS Finite Element Analysis
Abstract:
The performance of lock-rope mechanism affects the safe and efficient operation of mine hoisting system directly. The lock-rope mechanism with wedge angle 5° was designed by the mechanical analysis of wedge lock rope. Its entity model was established and the dynamic process of working is simulated by using the ANSYS/LS-DYNA. The results show that the wedge lock rope mechanism has the ability of self-locking. The strengthening institutions can largely eliminate the relative slip momentum between the lock-rope wedge-block and wire rope, which make the movement trend gentle, reduce the wear between the lock-rope wedge-block and wire rope and improve the security of wedge lock-rope mechanism effectively. The local equivalent stress of lock-rope wedge-block and wire rope are both present in the increasing distribution gradually from the upper to the lower.
