The invention provides a lifting device capable of adjusting the height. The lifting device comprises two guide rails arranged in parallel and a lifting mechanism. The lifting mechanism comprises a lifting base, a sliding guiding track groove, lifting gallows and a left-handed and right-handed screw rod. The lifting base is arranged on the guide rails through four guiding wheels. The lifting base is of a frame structure with no cover. The sliding guiding track groove is formed in the bottom end of the lifting base. The lifting gallows are installed on the sliding guiding track groove through two sliding shaft blocks. Threaded holes are formed in the sliding shaft blocks. The left-handed and right-handed screw rod penetrates through the two sliding shaft blocks and is fixed to the lifting base through two bearings. The inner lifting gallows and the outer lifting gallows are driven through the left-handed and right-handed screw rod, so that the height of the inner lifting gallows and the height of the outer lifting gallows are adjusted, the problem that lifting and deflection operation cannot be achieved in the steel pipe conveying process in the prior art is effectively solved, and the lifting device is conveniently connected with other devices.
