电动葫芦吊钩位置和钢丝绳偏角的计算

The calculation of the hook position and wire rope deviation angle of electric hoist

在电动葫芦的起升机构中,若钢丝绳的缠绕方式简单,吊钩的位置和钢丝绳偏角可根据几何关系用手算算出。但对于复杂的缠绕方式,因复杂的空间力系,计算便困难了。本文给出了用计算机计算吊钩的位置、转角及钢丝绳与卷筒、滑轮间偏角的方法。

For the lifting mechanism of electric hoist, the hook position and wire rope deviation angle may becalculated manually from the geometric relationship, when the rope reeving system is simple. A complexreeving system makes the calculation difficult due to complicated space force system. This paper presents thecalculation of the hook position, its rotation angle and the deviation angle of wire rope in relation to drumand pulley.
