A tower type multi-stage linkage electric lifting device aims at solving the problems that hydraulic lifting is low in system efficiency, large in energy loss, low in running speed, low in positioning precision and poor in hydraulic system environment applicability, and is composed of five liftable structures, a servo motor is fixed to the input end of a speed reducer, the speed reducer is installed on a first-stage transmission box body, and a second-stage transmission box body is installed on a second-stage transmission box body. The reducer output shaft is connected with the driving gear; the transmission hexagonal tubes are sleeved end to end and penetrate through each stage of transmission box body, and a transmission gear is arranged at one end of each transmission hexagonal tube; a multi-stage transmission gear set is arranged in each stage of transmission box body, ball nuts are respectively arranged on two sides of each stage of transmission box body, and a transmission gear is respectively arranged on one side of each stage of transmission box body; the ball screws and the ball nuts are supported and installed in the transmission box bodies of all stages through bearings, the connecting base can be installed on a lifted material, tower type layered arrangement is adopted, the structure is simple, the cost performance is high, the response is fast, and the precision is high; a pressure-free sealing structure is adopted, so that use and maintenance are convenient and fast.
