The invention relates to a transfer transition device. The transfer transition device comprises a base, a hydraulic device, a vertical column, supports and guide rollers. Multiple rollers are arrangedbelow the base. The hydraulic device comprises an oil tank, an oil pump, an oil cylinder and a throttle valve. A piston rod of the oil cylinder is fixedly connected with the lower end of the verticalcolumn. The guide rollers comprise the fixed guide roller and the movable guide rollers, inner rails and outer rails are arranged in the supports, the movable guide rollers are mounted in the inner rails through mounting seats, sliding blocks cooperating with the inner rails are arranged on the mounting seats, moving blocks are arranged at the positions of the outer rails, and magnetic parts withdifferent magnetic poles are arranged on the sliding blocks and the moving blocks separately. The hydraulic device is arranged in the transfer transition device for adjusting the height, the liftingefficiency is greatly improved, in addition, the moving blocks in the outer rails and the sliding blocks in the inner rails synchronously move based on the principle that the different magnetic polesattract each other, thus, the movable guide rollers are driven to move up and down, and different working condition requirements can be met.
