The through shaft type combined lifting hook for the crane comprises a main pulley yoke, auxiliary pulley yokes are detachably installed on the two sides of the main pulley yoke, and each auxiliary pulley yoke comprises an inner side plate, an outer side plate and a pulley; the main pulley yoke and the auxiliary pulley yoke are connected and fixed through a clamping structure and a connecting shaft. The clamping structure comprises a clamping groove formed in the outer face of a side plate of the main pulley yoke and a buckle arranged on the outer face of an inner side plate of the auxiliary pulley yoke, and the clamping groove horizontally limits the buckle. The connecting shaft penetrates through the main pulley yoke and the auxiliary pulley yoke, and a fastener is arranged at the end of the connecting shaft and horizontally limits the auxiliary pulley yoke. The clamping structure is used for positioning, the device can be prevented from shaking, the structure is more compact, and the mounting and dismounting processes are convenient and rapid; the connecting shaft penetrates through the main pulley yoke and the auxiliary pulley yoke, the overall stress of the structure is more stable and reasonable, and the large-interval hoisting requirement can be met; according to the invention, while the hoisting requirement is met, the equipment purchase and use cost can be effectively reduced.
本发明公开了一种起重机用通轴式组合吊钩,包括主滑轮架,主滑轮架两侧可拆卸地安装有副滑轮架,副滑轮架包括内侧板、外侧板和滑轮;所述主滑轮架和副滑轮架通过卡接结构和连接轴连接固定;所述卡接结构包括设置在主滑轮架侧板外面的卡槽和设置于副滑轮架内侧板外面的卡扣,卡槽对卡扣水平限位;所述连接轴贯穿主滑轮架和副滑轮架,端部设置紧固件并对副滑轮架水平限位。本发明使用卡接结构定位,可以避免装置晃动,结构更加紧凑,且安装、拆卸过程方便快捷;使用连接轴贯穿主滑轮架和副滑轮架,结构整体受力更加稳定合理,能够适应大区间吊重需求;本发明在满足吊重要求之余,可以有效降低设备购置、使用成本。
