绳索取心绞车排绳器关键问题研究

Research on Key Problems in Rope-arranging Device for Wire-line Core Winch

摘要:

在绳索取心绞车机械式排绳器的设计过程中，存在着2个突出的问题：一是为了确保靠滚筒挡板的钢丝绳准确换层，需要在双螺旋轴端部设计合适长度的过渡圆弧槽；二是滚筒旋转一圈排绳器移动的距离能与不同绳径钢丝绳相匹配。为了解决以上问题，以这2个问题的共同影响因素螺距和传动比设立方程，通过解方程组进行了准确计算。根据该计算结果设计的排绳器经野外现场试验证明实用可靠。

Abstract:

In the process of designing mechanical rope-arranging device, there are two outstanding problems. First, in order to ensure the rope next to roller shutter to change layers accurately, the transition circular groove with appropriate length should be designed on the end of double helix axis; then the moving distances of a turning circle of the roller rope-arranging device should match with the ropes of different diameters. To solve these problems, equations were established based on the common influencing factors of pitch and transmission ratio for accurate calculation. It is proved by the field testing that the rope-arranging device designed on the basis of the calculation results is practical and reliable.
