Further, the connecting shaft of the tail end lifting unit is connected with a high-power motor.
Furthermore, a connecting plate is arranged between the adjacent lifting platforms.
Furthermore, the roller groups are composed of four rollers.
Furthermore, the axes of the driving gear and the driven gear are all located at the same horizontal position.
Furthermore, the lifting platform extends outwards for a certain distance.
Has the advantages that: in the invention, a plurality of synchronous straight gear lifting mechanisms are adopted, and all lifting platforms can be lifted only by one high-power motor, and the lifting platforms are always lifted synchronously in the lifting process and are completely in a horizontal state, so that the equipment is prevented from inclining; meanwhile, the guide rail and the roller structure arranged in the lifting unit can improve the stability in operation, avoid shaking and improve the vertical precision of the lifting device.
