Abstract
A liftable pod-type inland ship bow side-pushing device mainly comprises a circular guide pipe, a pod-type motor-driven side-pusher and an oil hydraulic lifting mechanism, wherein the circular guide pipe is mounted below the designed waterline of a bow part and penetrates a ship body left and right; the pod-type motor-driven side-pusher is mounted in the circular guide pipe via a fixed sleeve and a fixed supporting rod; the oil hydraulic lifting mechanism is fixedly mounted on the wall of the circular guide pipe through an oil hydraulic rod base; two oil hydraulic lifting bars of the oil hydraulic lifting mechanism are connected and fixed with two ends of a fixed cross rod; and the middle of the fixed cross rod is connected with the fixed supporting rod. When the inland ship is loaded fully to sail, the ship body is soaked in water deeply, the distance between a ship bottom and a river bed bottom is smaller, and the oil hydraulic lifting mechanism lifts the pod-type motor-driven side-pusher into the circular guide pipe to form guide pipe-type side-pushing; and while the inland ship sails with no load, the bow part is soaked in the water shallowly and is easily exposed above the surface of water, and the oil hydraulic lifting mechanism lowers the pod-type motor-driven side-pusher to a part below the ship bottom to form bilge side-pushing. The side-pushing device eliminates the limitation of an inland waterway channel to the use of the bow side-pushing well.
