Abstract

The invention relates to an epsilon-type lifting hook device for crane, in particular to a lifting tool used for catching pieces and general cargo weights on a crane, which belongs to the technical field of crane machinery. The invention is characterized in that the lifting hook is arranged in a beam. A lifting hook nut is screwed up so as to fix a first bearing at the upper part of the lifting hook onto the beam. A lifting beam is arranged at the two sides of the beam and is combined with a spindle plate and fixed by bolts. A second bearing is arranged in a pulley and is covered by a bearing cover. A pulley shaft is arranged in a pulley bearing and the middle of the pulley shaft is provided with a support ring. The pulley block entirety assembled by the pulley, the second bearing, the bearing cover, the pulley shaft and the support ring is arranged in a lifting frame and the two ends thereof are blocked by catch plates. The assembly entirety assembled by the pulley block, the lifting frame and the catch plates is arranged in the lifting beam and fixed by a shaft, and the two ends thereof are blocked by catch plates and fixed by bolts. The invention is simple, compact and reasonable in structure, and safe and reliable in operation. The device effectively ensures the operating angle of a steel wire rope and well controls the sliding angle of the steel wire rope.

Description

technical field [0001] The invention relates to a mountain-shaped hook device of a crane, in particular to a spreader used on the crane for grabbing heavy objects such as cargo and miscellaneous goods, and belongs to the technical field of hoisting machinery. Background technique [0002] At present, in view of the purpose of crane operation, some of them are used in wharfs and freight yards to lift goods through wire ropes or special spreaders. The sheep eye hook used before can also lift small objects. Once it encounters larger objects such as steel plates, there will be certain hidden dangers in the fixing of the wire rope when it is lifted. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a crane hook device that is safe and reliable, can effectively ensure the working angle of the wire rope, and can well control the sliding angle of the wire rope. [0004] According to the technical solu...
