The invention discloses a multi-motor large-load electric cylinder for a crane in the technical field of electric cylinders, and aims to solve the problems that in the prior art, an electric cylinder of a traditional single-motor driving gear speed reducing mechanism cannot meet the requirements for large load, long stroke and the like needed by the crane, and the multi-motor large-load electric cylinder comprises a plurality of sets of driving assemblies, a reduction gearbox shell and a cylinder barrel. The cylinder barrel is connected with one side of the reduction gearbox shell, and the multiple sets of driving assemblies are evenly arranged on the reduction gearbox shell around the rod barrel. The lead screw is arranged in the rod barrel, the rod barrel is arranged in the cylinder barrel in a sleeved mode, a lead screw nut is arranged at one end of the rod barrel, the other end of the rod barrel extends out of the cylinder barrel to be connected with the rod head, and the lead screw nut is in threaded connection with the lead screw. A multi-motor driving mechanism can be adopted, and the requirements for large load, long stroke and the like of the electric cylinder for the crane are met.

    本发明公开了一种电动缸技术领域的起重机用多电机大载荷电动缸,旨在解决现有技术中传统单电机驱动齿轮减速机构的电动缸无法满足起重机所需的大载荷、长行程等问题,其包括多组驱动组件、减速箱壳体和缸筒,所述缸筒与减速箱壳体一侧连接,多组所述驱动组件围绕杆筒均匀设于减速箱壳体上;所述丝杠设于杆筒内,所述杆筒套设于缸筒内部,其一端设有丝杠螺母,另一端延伸至缸筒外部与杆头连接,所述丝杠螺母与丝杠螺纹连接。本发明可采用多电机驱动机构,满足起重机用电动缸载荷较大,行程较长等要求。
