Abstract
The invention discloses a crane hook device, relating to a crane hanger and aiming at solving the problem that the traditional hook device is easy to incline so that a hook side plate and the hook cannot maintain vertical to result in that the hook device is bent or broken. The crane hook device comprises two pulley supports, an upper connecting rod is arranged between the upper ends of the two pulley supports, and the two pulley supports are hinged with the upper connecting rod respectively by using two upper hinged shafts; and two side plates are arranged between two side faces of inner ports at the lower ends of the two pulley supports, the two pulley supports are hinged with the two side plates respectively by using two lower hinged shafts, and a hook cross beam is arranged between the two side plates. Because the height difference between two pulley shafts can be regulated by means of two pulleys through a parallelogram connecting-rod structure, wherein the parallelogram connecting-rod structure is formed by the two pulley supports, the upper connecting rod, the side plates as well as the lower hinged shafts and the upper hinged shafts, the hook device cannot incline to result in bending and fracturing accidents. The crane hook device can be applied to a four-suspension-point hoisting mechanism of a crane with large hoisting height.
