Segmented in-dock sliding carrying device with irregular curved surface structure

Abstract

The invention discloses an irregular curved surface structure segmented in-dock sliding carrying device which comprises a track frame, a sliding lifting trolley, a bottom tire tool and an irregular curved surface structure bulbous bow, the track frame is installed on the ground, the sliding lifting trolley is installed on the track frame, and the bottom tire tool is installed on the bottom tire tool. According to the method, the bottom tire tool and the sliding lifting trolley are arranged, a new carrying method is adopted, the irregular curved surface section sits on the special bottom tire tool, the irregular curved surface structure is moved in, moved out, lifted and descended through the sliding lifting trolley to complete dismounting and mounting of the irregular curved surface structure, the dismounting and mounting speed is high, and the working efficiency is high. By the adoption of the carrying method, tool materials can be saved, the maintenance cost of an enterprise is reduced, time and labor are saved during operation, the workload of workers is reduced, regular curved surface sections are seated on the bottom tire tool, the regular curved surface sections cannot overturn when subjected to strong wind of 9 grades or above, and the safety risk in the operation process is reduced.

Description

technical field [0001] The invention relates to the technical field of ships and ocean engineering, in particular to a sliding loading method in a segmented dock with an irregular curved surface structure. Background technique [0002] Bulbous bow, also known as "bulb bow", is a spherical protruding part below the water surface of the bow, which is a structure used to overcome the resistance of the ship. Its size and shape match the hull to offset the pressure of the water, resulting in a ship The waves are smaller, and the water flow near the hull can be improved to reduce the resistance of the ship. [0003] The ship bulbous bow refitting project is to change the original ship's bulbous bow shape, shape, size, optimize the bulbous bow line shape, find the best matching point between fuel consumption and speed, and reduce the resistance of wave-making to achieve energy saving. For the purpose of reducing emissions and improving navigation economy, the bulbous bow segment w...

[0003] The ship bulbous bow refitting project is to change the original ship's bulbous bow shape, shape, size, optimize the bulbous bow line shape, find the best matching point between fuel consumption and speed, and reduce the resistance of wave-making to achieve energy saving. For the purpose of reducing emissions and improving navigation economy, the bulbous bow segment with irregular curved surface structure is refitted in the floating dock. The base surface of the segment itself is irregular, and the installation position of the segment is special under the forecastle structure, so the crane cannot be directly hoisted. In place, due to the limitation of the height of the pier wood of 1.4 meters, the minimum height of the large flatbed truck in the general shipyard is 1.6 meters, which cannot meet the requirement of the height of 1.4 meters of the pier wood, so it is usually pulled in place by the hoist and then lifted by the hoist to close up in sections

[0004] However, due to the particularity of the irregular surface structure and the limitation of the installation location, it takes time and effort to assemble the winch, and there are certain safety problems in lifting the irregular surface structure by the winch. In view of this, it is necessary to invent a new loading method to solve the above problems
