The invention discloses a lifting mechanism based on clamping of different numbers. The lifting mechanism comprises a base; a motor is arranged in the base; a power output end of the motor is connected with a rotating shaft; the top end of the rotating shaft is hinged with a support arm; a cylinder is arranged between the rotating shaft and the support arm; a cross bar is arranged at a non-hinged end of the support arm; two fixed plates are symmetrically arranged on the cross bar; and two hanging hooks are at least arranged on the fixed plates in the vertical direction. The lifting mechanism solves the problems of labor waste and low working efficiency caused by a traditional pipe short-distance transportation mode, and can once clamp pipes with different numbers.
