The invention discloses a crane hoisting safety protection device, and relates to the technical field of crane equipment. A supporting plate which is located on the lower portion of a movable rod and used for bearing the movable rod is arranged on the lower portion of an auxiliary trolley, a main lifting hook is arranged on the lower portion face of the supporting plate, and a steel wire rope of a portal crane sequentially penetrates through the auxiliary trolley and the supporting plate and is fixedly connected with the main lifting hook; a plurality of auxiliary lifting hooks which are uniformly distributed around the main lifting hook and are used for carrying out secondary suspension protection on the lifted object are also arranged on the lower part surface of the supporting plate; brake mechanisms which are used for carrying out emergency suspension protection on the lifted object under the condition that the steel wire rope is accidentally broken or the lifted object is accidentally unhooked are arranged at two ends of the movable rod; according to the invention, the swinging of the hoisted object and the steel wire rope can be effectively prevented in the hoisting process, and secondary suspension limiting protection can be carried out on the hoisted object under the condition that the steel wire rope is accidentally broken or the hoisted object is accidentally unhooked, so that the accidental falling of the hoisted object in the hoisting process is effectively avoided, and a powerful guarantee is provided for the hoisting safety of the crane.

    本发明公开了涉及起重机设备技术领域的一种起重机吊运安全保护装置,辅助小车下部设有位于活动杆下部、且用于承托活动杆的支撑板,支撑板下部面设有主吊钩,门式起重机的钢丝绳依次贯穿辅助小车和支撑板、并与主吊钩固定连接,支撑板下部面还设有多个围绕主吊钩均匀分布、且用于对吊物进行二次悬吊保护的副吊钩,活动杆两端均设有在钢丝绳意外崩断或吊物意外脱钩情况下对吊物进行紧急悬吊保护的制动机构;本发明不仅可在吊运过程中有效防止吊物及钢丝绳的摆动,而且还能在钢丝绳意外崩断或吊物意外脱钩情况下,对吊物进行二次悬吊限位保护,有效避免了吊运过程中吊物的意外坠落,为起重机的吊运安全提供了有力保障。
