The invention discloses an anti-unhooking device for a crane hook. When the lifting hook lifts goods, the handle is located at the top end of the sliding groove, and the buckle below the handle is in contact with the sliding groove, so that the position of the handle is fixed, and even if the handle is collided by an obstacle, the handle cannot slide, and the lifting rope cannot fall off. The square hole at the front end of the baffle is perfectly attached to the hook tip, so that the lifting hook is in a closed state and is safer and more reliable. After the goods are hoisted, the rotating sleeve at the rear end of the handle is twisted, and the torsion spring drives the pulley block to move, so that the buckle contracts inwards, the handle can freely move along the sliding groove, the baffle is lifted up immediately, and the hoisting rope is picked. The anti-unhooking device is easy to operate and has higher safety and reliability.
本发明公布了一种起重机吊钩防脱钩装置。当吊钩吊运货物过程中,手柄处于滑槽的顶端,其下方的卡扣与滑槽接触,使得手柄位置固定,即使受到障碍物的碰撞,也不会使得手柄滑动,不会造成吊绳的脱落。挡板前端方孔与钩尖完美贴合,使得吊钩处于封闭状态,更加的安全可靠。吊运货物结束之后,通过扭动手柄后端的旋转套,扭簧带动滑轮组的运动,使得卡扣向里收缩,从而使得手柄可以沿着滑槽自由移动,挡板随即被抬起,实现吊绳的摘取。所述防脱钩装置操作简单,具有更高的安全性与可靠性。
