The invention relates to a positioning device, in particular to an anti-rotation positioning device for a lifting hook. According to the anti-rotation positioning device for the lifting hook, the state of the lifting hook can be automatically adjusted when cargoes are lifted and put down, and the cargoes can be hooked conveniently. According to the technical scheme, the anti-rotation positioning device for the lifting hook comprises a connecting seat, a connecting plate, a bearing seat, a driving shaft, a first pressure plate, a second pressure plate and the like, two connecting plates are symmetrically and fixedly connected to the connecting base, a bearing base is fixedly connected to the two connecting plates jointly, a driving shaft is rotationally connected to the bearing base, a first pressing disc is fixedly connected to the driving shaft, a second pressing disc is connected to the driving shaft, and the driving shaft is sleeved with a reset spring used for pushing the first pressing disc and the second pressing disc to reset upwards. Through cooperation of the lifting hook, the connecting block, the limiting mechanism, the limiting groove and the hexagonal prism, the defects that in the prior art, the state of the lifting hook cannot be automatically adjusted when goods are lifted and put down, and the adjusting efficiency is low are overcome.
本发明涉及一种定位装置,尤其涉及一种吊钩防旋转定位装置。技术问题为:提供一种可以在吊起和放下货物时自动调节吊钩状态,并且便于勾住货物的吊钩防旋转定位装置。技术方案是:一种吊钩防旋转定位装置,包括有连接座、连接板、承载座、主动轴、第一压盘、第二压盘等;连接座上对称的固接有两个连接板,两个连接板上共同固接有承载座,承载座上转动连接有主动轴,主动轴上固接有第一压盘,主动轴上连接有第二压盘,主动轴上套有用于推动第一压盘和第二压盘向上复位的复位弹簧。通过吊钩、连接块、限位机构、限位槽和六棱柱的配合克服了现有技术中的吊钩不能在吊起和放下货物时自动调节吊钩的状态和调节的效率较低等缺点。
