提升尾绳运行状态及导向方案研究

Research on operation state of hoist tail rope and guidance scheme

在多绳摩擦提升系统中,尾绳处于自然下垂状态,横向刚度较弱,在井筒风速较大、容器运行速度较快的情况下,极易产生大幅度的横向偏移,影响提升容器的平稳运行,严重时甚至导致尾绳扭结或与井筒内其他部位发生碰撞。为了准确评估提升系统运行过程中尾绳的运行特性及其对系统的影响,利用ADAMS软件建立摩擦式提升系统的虚拟样机模型,对尾绳的运行状态进行研究,并提出有效的尾绳导向方案。

In the multi-rope friction hoisting system,the tail rope is in natural drooping state,thus its lateral stiffness is weak,and great lateral deviation easily happens to it at the time of large wind speed in shaft and fast operating speed of the container,which affects the stable operation of the container hoisting,even results in kinking of tail rope or collision with other parts in shaft.In order to accurately evaluate the operation characteristics of the tail rope during operation of the hoisting system and its influence on the system,ADAMS was applied to establish the virtual prototype model of the friction hoisting system and research the operation status of the tail rope.Moreover,effective tail rope guidance scheme was put forward.
