Description

Rotation device for lightering platform
Technical Field
The invention relates to the technical field of ships, in particular to a rotating device for a lightering platform.
Background
The lightering operation refers to the cargo loading and changing operation between a cargo ship and a barge at an anchor ground, a mooring buoy and a wharf. Organizing overwater refute operation is an effective measure for solving the problem of insufficient berth. The method is particularly beneficial to the overwater refuting operation of the reloading port organization, because the method does not need to fix buildings on land and can perform dispersed operation, thereby occupying less limited shore line and land resources and saving the loading and unloading cost. The refuting operation is also suitable for ports and water areas with insufficient water depth of port channels, and in order to enable a large ship to directly enter the port for operation, a part of cargos of a heavy-duty ship needs to be unloaded at an anchor land so as to reduce the draught of the ship and accelerate the operation. The overwater refuting operation needs to pay special attention to the connection of the transfer tool, safety measures are enhanced, and the loading and unloading conditions required by the overwater refuting operation, such as loading and unloading machinery, power, illumination, communication, overwater vehicles and the like, are guaranteed.
When the ship is refuted at sea, the roll-on ship tail springboard is carried on another ship, under the action of wind waves, the two ships shake violently, the relative movement of the two ships is large, the two ships need to be refuted in parallel, and the safety is improved. The roll-on springboard for passenger transport wharf automobiles with the bulletin number of CN 207029483U discloses a structural design of a springboard body adopting a multi-structure, wherein the height of the springboard body can be changed by fixing the springboard at the lower side of a support frame and rotating the springboard at the upper side. The retractable ship diving board device with the bulletin number of CN 208498738U discloses a structure for supporting a diving board and a tail board through a first rotating mechanism and a second rotating mechanism, which can complete the putting or retracting operation in a short time. A refuting platform with a publication number of CN 108482589A discloses a refuting platform with a main springboard and an auxiliary springboard adjusted in height through telescopic steel wire ropes, and the stability of the refuting platform is improved. "a diving board for ship", with a bulletin number of CN 204507189U, discloses a diving board for ship, which completes the setup login at sea by adjusting the height of the inner base pillar, rotating the base, extending the second diving board and adjusting the inclination angle of the diving board.
However, the conventional roll-on-roll-off ship for the automobile adopts the straight stern springboard as the stern springboard, and the conventional roll-on-roll-off ship can only be erected from front to back and cannot be erected obliquely, so that the conventional roll-on-roll-off ship is inconvenient for workers to operate.
In addition, the inclined springboard is folded and unfolded through the lifting device, the floor area of the springboard is too large, and the inclined springboard cannot be installed on a stern door frame of a ship as a stern sealing springboard.
