The invention discloses a lifting hook pulley block with 1 and 2 multiplying power conversion, which comprises a side plate assembly for mounting a fixed pulley and a cargo boom end section for mounting a displacement pulley, and a steel wire rope is sequentially wound on the displacement pulley and the fixed pulley and then is fixed on an adapter. And the adapter is detachably mounted on the side plate assembly and the end section of the cargo boom so as to realize switching between 1 multiplying power and 2 multiplying power. By changing the connection position of the adapter and the position of the displacement pulley of the end section of the cargo boom, the one-multiplying-power and two-multiplying-power conversion of the movable arm type tower crane can be realized.

    本申请公开了一种1、2倍率变换的吊钩滑轮组,包括安装固定滑轮的侧板组件以及安装变位滑轮的起重臂端部节,钢丝绳依次绕设于所述变位滑轮与所述固定滑轮后固定于适配器,所述适配器可拆卸安装于所述侧板组件以及所述起重臂端部节以实现1、2倍率切换。本发明通过更改适配器的连接位置和起重臂端部节的变位滑轮的位置即可实现动臂式塔机的1、2倍率变换。
