The invention relates to a lifting device based on a locking sleeve hydraulic cylinder and a control system and method.The lifting device comprises a lifting tower, the lifting tower comprises a plurality of tower bodies which are sequentially arranged in a sleeved mode and are in sliding fit, the tower body on the lowest side is a first-stage tower body, and the stages of the other tower bodies are sequentially increased from bottom to top; a locking sleeve hydraulic cylinder is arranged between the first-stage tower body and the second-stage tower body, transmission mechanisms distributed in the circumferential direction are arranged among the three adjacent tower bodies respectively, the three adjacent tower bodies correspond to an n-stage tower body, an (n + 1)-stage tower body and an (n + 2)-stage tower body, n is larger than or equal to 1, each transmission mechanism comprises a pulley and a steel wire rope, the pulleys are installed at the tops of the (n + 1)-stage tower bodies through wheel carriers, and the steel wire ropes are connected with the pulleys through steel wire ropes. One end of the steel wire rope is fixed to the bottom of the n-stage tower body, the other end of the steel wire rope bypasses the pulley and is fixed to the bottom of the n + 2-stage tower body, and the device has the advantages of being simple in structure, convenient to control, reliable in locking, good in stability and high in practicability; the control system and method have the advantages of being convenient to control, safe and reliable.
