The invention relates to the technical field of cranes, in particular to a suspension type electric double-hoisting crane. The suspension type electric double-hoisting crane comprises an electric trolley; a hoisting device is connected to the electric trolley; a base is fixedly mounted on the hoisting device; a side groove and a center groove are formed in the base; a driving rod is rotationally mounted in the side groove and the center groove; the driving rod is provided with a first lead screw pair and a second lead screw pair; the first lead screw pair is in threaded connection with a first nut; the second lead screw pair is in threaded connection with a second nut; the first nut and the second nut are both connected with lifting hooks; the lifting hooks are slidably connected between a reinforcing rod and a through groove; and a driven bevel gear is fixedly mounted on the driving rod. Rib films are connected to the surfaces of the lifting hooks as safety state early warning mechanisms, and can directly reflect the stress condition of the lifting hooks, the rib films are connected to emergency protection mechanisms arranged on the surfaces of the lifting hooks, and the emergency protection mechanisms are triggered when the lifting hooks crack and stress changes.

    本发明涉及起重机技术领域,具体为一种悬挂式电动双吊起重机,包括电动小车,所述电动小车上连接有吊装器,且吊装器上固定安装有底座,所述底座上设置有侧槽和中心槽,且侧槽和中心槽中转动安装有驱动杆,所述驱动杆上设置有第一丝杆副和第二丝杆副,且第一丝杆副上螺纹连接有第一螺母,且第二丝杆副上螺纹连接有第二螺母,所述第一螺母和第二螺母上均连接有吊钩,且吊钩滑动连接在增强杆和通槽之间,所述驱动杆上固定安装有从动锥齿轮;在吊钩表面连接有筋膜作为安全状态预警机构,能够直接的反应吊钩的受力情况,并且筋膜连接在吊钩表面设置的应急防护机构上,在吊钩出现裂隙、应力变化时,触发应急防护机构。
