The invention provides a lifting hook device with pulley blocks and an operation machine, and relates to the field of operation machinery. The lifting hook device with the pulley blocks comprises a lifting hook, at least two movable pulley blocks and at least two static pulley blocks; the movable pulley blocks are arranged on the lifting hook at intervals; each movable pulley block comprises two movable pulleys arranged at an interval, and the movable pulleys are in running fit with the lifting hook; the static pulley blocks are arranged on a suspension arm at intervals and are in one-to-one correspondence with the movable pulley blocks in position; and the static pulley blocks are connected with the movable pulley blocks through steel wire ropes and each comprise two static pulleys arranged at an interval, the static pulleys are in running fit with the suspension arm, and the axes of the static pulleys are perpendicular to the axes of the corresponding movable pulleys. The two movable pulley blocks and the two static pulley blocks are arranged at intervals, and the axes of the static pulleys are perpendicular to the axes of the corresponding movable pulleys, so that the distance between the two movable pulley blocks on the lifting hook is much larger than that of a traditional lifting hook, the lifting hook is prevented from rotating, and the safety of the lifting hook is improved.

    本发明提供一种带有滑轮组的吊钩装置及作业机械,涉及作业机械领域,带有滑轮组的吊钩装置包括吊钩、至少两组动滑轮组和至少两组静滑轮组,动滑轮组间隔设置于吊钩,动滑轮组包括两个间隔设置的动滑轮,动滑轮与吊钩转动配合;静滑轮组间隔设置于吊臂上,且与动滑轮组的位置一一对应;静滑轮组通过钢丝绳与动滑轮组连接,静滑轮组包括两个间隔设置的静滑轮,静滑轮与吊臂转动配合,静滑轮的轴线与对应的动滑轮的轴线垂直。通过将两组动滑轮组和两组静滑轮组分别间隔设置,并且静滑轮的轴线与对应的动滑轮的轴线垂直,使得吊钩上两组动滑轮组之间的距离比传统吊钩的间距大很多,避免吊钩发生打转,提高吊钩的安全性。
