【摘要】 分离机构是油管机械化排放装置的组成部分，它能够自动地从整排油管中分离出单根油管，并运到指定位置。如设置一种动力机构来完成上述动作，则结构必然复杂和庞大。鉴于此，提出了一个不外设动力源，而仅靠油管和结构自身重力来实现分离油管的机构。分析了其工作原理，给出了有关运动学和动力学的解析式，进而进行了优化设计计算，得出了各部结构尺寸及重量分配的最佳关系。更多还原

【Abstract】 The Separation mechanism is a component of the mechanized tubing landling unit, which can automatically Separate a single tubing from the tubing layer and transfer it to the pointed position. If a mechanism with power source is used to accomplish the above-mentioned action, the mechanism must be complicated and large. In this article, a new mechanism, which has no additional power source and carries out tubing separation by the sole weight of the tubing and the mechanism, is presented. The working principle of the mechanism is analyzed, the relevant kinematic and dymamic analytical expressions are given, thereby optimization is completed, and the optimum relation between the dimensions and weight of each compoent part is obtrined.更多还原
