Abstract

The utility model relates to an unhooking prevention device which comprises a fixed plate assembly, a U-shaped rod assembly and a locking screw. The fixed plate assembly comprises a fixed plate. The upper end face of the fixed plate is provided with an arc surface groove. Lifting hook clamp plates are respectively on the upper end face of the fixed plate and at both sides of the arc surface groove. The lower end faces of the two lifting hook clamp plates are respectively welded and fixed on the fixed plate. After a positioning bolt passes through bolt holes on the two lifting hook clamp plates, a nut is screwed down to carry out positioning. The U-shaped rod assembly comprises a U-shaped rod and a connecting steel plate. After both left and right side bars of the U-shaped rod respectively pass through corresponding shaft holes on the fixed plate, screw thread sections at the upper ends of the left and the right side bars respectively pass through corresponding shaft rod through holes on the connecting steel plate. Nuts are respectively screwed down on the screw thread sections at the upper ends of the left and the right side bars of the U-shaped rod so as to carry out positioning. A screw thread section of the locking screw is screwed down in a threaded hole on the lateral surface at one end of the fixed plate. The device is a detachable unhooking prevention device. The device is arranged on a lifting hook, is convenient to install and is safe and reliable. Casualties and equipment loss which are caused by unhooking can be avoided.
