The invention relates to the technical field of cranes, and discloses an emergency auxiliary supporting device for a crane. The emergency auxiliary supporting device comprises a vehicle body, whereina long rod is fixedly connected with the interior of the vehicle body, and a supporting plate is movably connected with the exterior of the long rod in a sleeving mode. A supporting rod is movably connected with the interior of the supporting plate in a sleeved mode, and a magnet is fixedly connected with the exterior of the supporting rod. A rack is fixedly connected with the exterior of the supporting rod, a gear meshes with the exterior of the rack, and a rotating rod is fixedly connected with the interior of the gear in a sleeved mode. By means of the interaction of a glass tube, a steel ball, contact pieces, a first spring, the supporting plate, the supporting rod, a first electromagnet, the first magnet, a ratchet wheel, the gear, the rack, a limiting assembly and the rotating rod, when the phenomenon that the crane is inclined due to the fact that the weight of an object hoisted by the crane is larger than the maximum limit value of the crane happens, the auxiliary supporting effect on the crane can be achieved, and the phenomena that due to the excessive inclination of the crane, the whole crane topples, and then the irreparable loss is caused are avoided.
本发明涉及起重机技术领域,且公开了一种用于起重机的应急辅助支撑装置,包括车体,所述车体的内部固定连接有长杆,所述长杆的外部活动套接有支撑板,所述支撑板的内部活动套接有支撑杆,所述支撑杆的外部固定连接有磁铁,所述支撑杆的外部固定连接有齿条,所述齿条的外部啮合有齿轮,所述齿轮的内部固定套接有转杆;通过玻璃管、钢珠、触片、弹簧一、支撑板、支撑杆、电磁铁一、磁铁一、棘轮、齿轮、齿条、限位组件以及转杆的相互作用,使得起重机在吊装的物品重量超过起重机最大限值导致起重机发生倾斜时,能够对起重机起到辅助支撑的作用,防止了起重机倾斜过度导致起重机整体发生倾倒,进而造成无法挽回的损失。
