The column-type building construction machine lifting system according to claim 6, characterized in that: The intelligent control unit further includes: a dual closed-loop control module, with an inner loop as a flow control loop for detecting the volume and flow rate of hydraulic oil inside the hydraulic cylinder, and an outer loop as a position control loop for detecting the extension or retraction of the hydraulic cylinder; a data storage module that continuously collects and stores data on the initial position and actual position of the hydraulic cylinder after each use, as well as the calculated error data; and an adaptive correction module that calculates the extension and retraction error of the hydraulic cylinder based on the detection data from the distributed sensing unit, and automatically controls the movement of the hydraulic cylinder based on the error value until the error value is within the error range and less than one centimeter. The electro-hydraulic servo drive unit also includes a flow dynamic distribution module, which adjusts the displacement of the variable piston pump and the opening of the servo valve according to the extension and retraction direction of the hydraulic cylinder and the load size.
