Crane hook anti-rotation locating device

Abstract

The invention discloses a crane hook anti-rotation locating device comprising a pulley assembly, a hook assembly and a locating assembly. The pulley assembly comprises a pair of parallel lifting yokeplates and a pulley block arranged between the lifting yoke plates. The upper sections of the lifting yoke plates are connected through a rotary shaft of the pulley block. The lower sections of the lifting yoke plates are connected through first and second crossbeams. The hook assembly comprises a hook and a sinking device arranged at the upper end of the hook. The locating assembly is arranged between the first crossbeam and the second crossbeam. According to the crane hook anti-rotation locating device, through combined action of the sinking device and the locating assembly, the hook can freely rotate under the no-load condition, in addition, when goods are hung, a sinking assembly of the hook can enable the hook to sink slightly, the locating assembly is driven to push a locating pin tobe inserted into a locating blind hole, and thus danger caused by rotation of the hook is eliminated when the goods are hung on the hook.

Description

technical field [0001] The invention specifically relates to a crane hook anti-rotation positioning device. Background technique [0002] There are two types of hook sets for cranes: the traditional type and the anchor hook type. When the traditional type of hook set lifts heavy objects, due to the deviation of the center of gravity of the heavy objects or the inclination of the steel wire rope, the hooks are often caused when the object is lifted off the ground. The hook head and the heavy object swing or rotate continuously for a long time, which is prone to bumping and causing unnecessary economic losses, especially when lifting special items such as high temperature and easy corrosion, there is still a relatively large safety hazard; and Although the anchor hook type hook group does not have the above problems, it has high requirements for the placement of lifting objects and is inconvenient to operate; at present, the positioning of the hook in the prior art depends on ...

[0002] There are two types of hook sets for cranes: the traditional type and the anchor hook type. When the traditional type of hook set lifts heavy objects, due to the deviation of the center of gravity of the heavy objects or the inclination of the steel wire rope, the hooks are often caused when the object is lifted off the ground. The hook head and the heavy object swing or rotate continuously for a long time, which is prone to bumping and causing unnecessary economic losses, especially when lifting special items such as high temperature and easy corrosion, there is still a relatively large safety hazard; and Although the anchor hook type hook group does not have the above problems, it has high requirements for the placement of lifting objects and is inconvenient to operate; at present, the positioning of the hook in the prior art depends on manual insertion and removal of the pin to realize the positioning of the hook. Anti-rotation positioning, this process is cumbersome and unsafe in hoisting operations. Once there is a hook omission, it is easy to rotate the hook, which will lead to swinging or even tipping accidents
