The invention provides a heavy-load multi-stage telescopic stand column structure. The heavy-load multi-stage telescopic stand column structure comprises a driving motor, a first transmission assembly, a first-stage stand column, a second-stage stand column and a third-stage stand column. The driving motor is fixedly installed on the fixing box, a first transmission assembly is connected into the fixing box and used for driving the lifting assembly, the lifting assembly is used for driving the second-stage stand column to ascend and descend, the second-stage stand column is movably arranged in the first-stage stand column in a sleeved mode, and the third-stage stand column is movably arranged in the second-stage stand column in a sleeved mode. The second-stage stand column lifts to drive the third-stage stand column to lift through a second transmission assembly; the extension and retraction of each stage of the multi-stage range-extending lifting column are realized by arranging a lead screw pair and a chain wheel and chain transmission structure, and the technical problems of complex processing, high mounting difficulty, high cost, long production period and weak bearing capacity of the existing traditional multi-stage upright column formed by mutually sleeving a plurality of lead screw pairs are solved.

    本发明提供了一种重载多级伸缩立柱结构,包括驱动电机、第一传动组件、第一级立柱、第二级立柱、第三级立柱;所述驱动电机固定安装在固定箱上,所述固定箱内连接有第一传动组件,所述传动组件用于驱动升降组件,所述升降组件用于驱动第二级立柱升降,所述第一级立柱内活动套设有第二级立柱,所述第二级立柱内活动套设有第三级立柱,第二级立柱升降通过第二传动组件带动第三级立柱升降;本发明通过设置一支丝杠副及链轮链条传动结构实现多级增程升降柱的每级伸出与缩回,解决了现有的传统的通过多根丝杠副相互套装在一起构成的多级立柱具有的加工复杂、安装难度大、成本高、生产周期长、承载力弱的技术问题。
