The invention discloses a semitrailer steering device with steerable wheels. The semitrailer steering device comprises wheel axles, steerable wheel assemblies and a driving system, wherein a mounting base is arranged in the middle of each wheel axle; each mounting base comprises a mounting bottom plate through which a vertical pin shaft penetrates and a mounting top plate through which the vertical pin shaft penetrates; each vertical pin shaft is hinged to a steering base; each steering base comprises a transverse plate and a longitudinal plate, which are integrated into a whole; the middle of each transverse plate and the front part of the corresponding longitudinal plate are hinged to the corresponding vertical pin shaft; two ends of the transverse plate which is close to one side of the driving system are respectively hinged to output ends of steering driving oil cylinders; every two adjacent transverse plates are connected together through a longitudinal pull rod; the longitudinal pull rods are in staggered arrangement; two connecting parts are arranged at the rear edge of each longitudinal plate; each connecting part is connected with the corresponding steerable wheel assembly through a transverse pull rod and a steering arm. When the wheel axles deviate while the semitrailer runs, only the steering driving oil cylinders are controlled so as to align the foremost wheel axle, so that the wheel axles behind the foremost wheel axle can be aligned through the longitudinal pull rods; the semitrailer steering device is suitable for semitrailers which transport wind turbine tower cylinders and run on curved mountain roads.
