The invention belongs to the technical field of deicing equipment, and discloses an overbridge deicing device which comprises a
machine shell, a six-wheel rocker
chassis structure is fixedly connected to the bottom of the
machine shell, rocker arms are movably connected to the two sides of the
machine shell, a motor base is fixedly connected to the interior of the machine shell, a motor is fixedly connected to the interior of the motor base, and the motor is fixedly connected to the interior of the motor base. One side of the motor is fixedly connected with a
gear transmission mechanism, and one end of the
gear transmission mechanism is fixedly connected with a chain wheel transmission mechanism. By arranging the six-wheel rocker
chassis structure, the
gear transmission mechanism, the cleat roller, the melting mechanism, the ice sweeping mechanism and other structures, the cleat roller is rotated, the ice surface is stripped through surface protrusions of the cleat roller, after the ice surface is removed, stripped and crushed through the cleat roller, microwaves are emitted through a
microwave tube of the melting mechanism, the step surface is heated, and the step surface is cleaned. Therefore, an overhard ice layer can be thoroughly removed, and
physical exhaustion and injury risks of deicing personnel are reduced.
