The invention discloses a cargo falling prevention device for an automatic crane and a using method thereof. The device comprises two parallel transverse hanging frames, a flat mounting plate, a leftprotecting plate and a right buckling plate, the flat mounting plate is arranged above the middle portion between the two transverse hanging frames, and a cuboid-shaped top buckling plate is arrangedabove the flat mounting plate in parallel. The device has the beneficial effects that two second push clamping blocks clamp and fix the two sides of the upper end of a lifting hook respectively, so that the device, a cable chain and the lifting hook on the crane are clamped and fixed, and the device can conveniently protect cargoes lifted by the crane; and a second hydraulic cylinder pushes firstpush clamping blocks to move to guarantee that the device can be fixedly clamped to cable chains and lifting hooks in different specifications and sizes for work, the four first push clamping blocks are clamped around the cable chain in the circumferential direction, the second push clamping blocks are clamped on the two sides of the lifting hook respectively, it is guaranteed that the device, thecable chain and the lifting hook on the crane are clamped and fixed more firmly, and the device is very convenient and fast to assemble, use or disassemble.
本发明公开了一种自动化起重机防货物掉落装置及其使用方法,包括两个呈平行设置的横挂框、平装板、左护盘和右扣板,两个横挂框之间中部上方设置有平装板,且平装板上方平行设置有长方体形结构的顶扣板。本发明的有益效果是:两个第二推夹块分别对吊钩上端两侧进行夹紧固定,从而将该装置与起重机上的索链和吊钩夹接固定,方便该装置对起重机起吊的货物进行防护工作,通过第二液压缸推动第一推夹块活动,保证该装置能够固定夹接在不同规格大小的索链和吊钩上工作,四个第一推夹块周向围绕在索链周围对其夹紧,第二推夹块分别在吊钩两侧对其夹紧,保证该装置与起重机上的索链和吊钩夹接固定更加紧固牢靠,且该装置安装使用或拆卸十分方便、快捷。
