Multifunctional shipborne excavating loading/unloading machine

The invention provides a multifunctional shipborne excavating loading/unloading machine which comprises a walking mechanism, a rotating mechanism, a loading/unloading mechanism and a control system. The walking mechanism is composed of a large-vehicle walking mechanism body and a small-vehicle walking mechanism body arranged on the large-vehicle walking mechanism body. The large-vehicle walking mechanism body is composed of large-vehicle beams and a connection rotating shaft arranged on the large-vehicle beam. The two ends of the connection rotating shaft are provided with connection rotating shaft bodies and large-vehicle walking speed reducers respectively. The small-vehicle walking mechanism body is composed of a small-vehicle frame, small-vehicle walking wheels and small-vehicle walking rails. The small-vehicle walking rails are arranged on the large-vehicle beams. The small-vehicle walking wheels are arranged below the small-vehicle frame. One side of the small-vehicle frame is provided with a cab. The rotating mechanism is arranged above the small-vehicle frame, and the loading/unloading mechanism and the control system are arranged on the rotating mechanism. The multifunctional shipborne excavating loading/unloading machine is flexible and changeable in function and capable of meeting requirements of different works and increasing the equipment utilization rate to the maximum degree.
