Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] like Figure 1 to Figure 5 As shown, the present invention is a welded box structure surrounded by three sides and floating on the water surface in a C shape, including longitudinal floating bodies 1 on both sides and horizontal floating bodies 2 that are vertically fixedly connected to the longitudinal floating body 1 at both ends, the vertical floating body 1 and the horizontal floating body. The lower part of the buoyant body 2 is provided with multiple groups of empty chambers 11, which provide sufficient buoyancy for the present invention. Diesel generator set compartment 21 and fuel tank 22 are adjacently arranged in the bottom of transverse buoyancy body 2, which can save fuel delivery pipelines and also reduce the center of gravity of the present invention. The main deck 23 of the transverse buoyant body 2 of the present embodiment is provided with 2 lay...

Abstract

The invention discloses a ship floating maintenance platform which comprises longitudinal floating bodies on the two sides and a transverse floating body vertically and fixedly connected with the longitudinal floating bodies. A ship tail lifting device stretches across the middles of the two longitudinal floating bodies, and comprises a pair of vertical gantries, a ship tail lifting beam and a ship tail lifting beam lifting mechanism, and the ship tail lifting beam stretches across the inner sides of the two longitudinal floating bodies and comprises a lower cross beam and a pair of stand columns. The lower ends of the vertical segments of the stand columns are fixedly connected with the two ends of the lower cross beam respectively, and the ship tail lifting beam lifting mechanism comprises a fixed pulley set, a movable pulley set and a loading winch. A stand column lifting guide mechanism is arranged between concave openings in the inner sides of the longitudinal floating bodies and the vertical segments of the stand columns, and stand column locking mechanisms are symmetrically arranged on the two sides of the stand columns. The ship floating maintenance platform is reasonable in arrangement and fast and convenient to use, the tail of a ship can be lifted fast, a rudder blade and a propeller are made to be out of water for maintenance, and maintenance cost is lowered. Use time is short, and work efficiency is high. The ship repairing cost is greatly lowered.

Description

[0001] Technical field: [0002] The invention relates to a special platform for repairing the stern of an inland river transport ship, in particular to a floating platform capable of lifting the stern of the ship out of the water for maintenance, and belongs to the technical field of ship engineering. [0003] Background technique: [0004] The propeller, rudder, rudder stock and shafting at the tail of the ship are prone to damage after long-term operation. How to quickly complete the repair will directly affect the economic benefits of the ship's operation. Usually choose to go to the berth or enter the dock for maintenance. The inclined berth on the ship is more difficult, and the occupancy rate of the dock is high. Affect ship operating costs. The research and development of a special platform specially used for water discharge at the stern of the ship for rapid maintenance can greatly reduce the cost of ship maintenance, and has become a major problem that the ship repai...
