The intelligent anti-unhooking device comprises a lifting hook body, the interior of the lifting hook body is arranged in a rectangular hook shape, a lower pressing plate is slidably connected to the inner bottom of the lifting hook body, a liquid storage cavity is formed in the bottom end of the lifting hook body, and the liquid storage cavity is filled with hydraulic oil; and a first sliding plate is slidably connected into the liquid storage cavity, two sliding rods are fixedly connected between the upper side of the first sliding plate and the lower pressing plate, the two sliding rods are each sleeved with a first spring, and the two ends of each first spring abut against the side wall of the lifting hook body and the side wall of the lower pressing plate correspondingly. When the crane hook body hangs a rope, under the gravity of the rope, the bumping post ascends to enable the hook body to form a sealing rectangular ring, the rope can be prevented from being separated from the inside of the hook body 6, and meanwhile, the rope can be actively and tightly clamped between the upper pressing plate and the lower pressing plate when the rope slides or shakes, so that the rope is prevented from falling off. The rope is prevented from being separated from the lifting hook main body.
本发明公开了一种起重机吊钩智能防脱钩装置,包括吊钩主体,所述吊钩主体内呈矩形勾状设置,所述吊钩主体的内底部滑动连接有下压板,所述吊钩主体的底端内部开设有储液腔,所述储液腔内填充有液压油,所述储液腔内滑动连接有第一滑动板,所述第一滑动板上侧与下压板之间固定连接有两个滑动杆,两个所述滑动杆上均套设有第一弹簧,每个所述第一弹簧的两端分别抵在吊钩主体和下压板的侧壁上。本发明当起重机吊钩主体挂起绳索时,在绳索的重力下,挡柱上升可将吊钩主体可形成一个密封矩形环,可防止绳索从吊钩主体6内脱离,同时还可主动在绳索发生滑动或晃动时,将绳索紧紧夹持在上压板和下压板之间,避免绳索脱离吊钩主体,安全性高。
