Description
Technical Field
The invention relates to the technical field of ships, in particular to a large-scale marine elevator structure.
Background
Marine elevators are used primarily for vertically moving cargo from a main deck to a cargo hold deck or for vertically moving cargo from a cargo hold deck to a main deck. At present, two types of large marine elevators are generally used, one type of large marine elevator is a steel wire rope type elevator; the other is a cross-type elevator with a hydraulic top cover installed on the main deck. Both types of elevators have certain drawbacks.
In a steel wire rope type elevator, a pit is required to be formed in a deck of a cargo hold, and in a large ship, the pit is generally used as a place for carrying large-scale activities due to a large space in the cargo hold, and occupies a part of the space, which causes inconvenience.
The cross type lifter with the main deck provided with the hydraulic top cover needs to open the top cover on the main deck before use. The connection between the roof and the main deck may be articulated or sideslip. For the hinged type, when the top cover is opened, a hydraulic cylinder is needed to jack the top cover to the hinged side. For the side slide type, a hydraulic cylinder is required to exert a force on the top cover to slide it toward one side. In either case, a large amount of space is reserved in the main deck for the placement of hydraulic cylinders and joints such as hinges. These take up a lot of space on the main deck, thus compressing the space available for the main deck and affecting the placement of other equipment.

Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
As shown in fig. 1, 2, 3, 4, 5, 6, and 7, the large marine elevator structure includes a jack-up type elevator 20 provided on a cargo compartment deck 10 and capable of moving cargo between the cargo compartment deck 10 and a main deck 11, and the main deck 11 is provided with a hatch 12 for cargo entry and exit.
A top cover 30 is provided inside the hatch 12 of the main deck 11. The retractable supporting component 40 is arranged on the hatch wall of the main deck, the supporting component 40 is inserted into the side wall of the top cover 30 after extending out, and the upper surface of the top cover 30 is flush with the upper surface of the main deck 11.
The side wall of the top cover 30 is provided with an accommodating space for accommodating the supporting part, and the supporting part 40 is separated from the top cover after being contracted; the support members 40 are in plurality, distributed circumferentially along the hatch wall of the main deck.
The supporting component can be a telescopic plate, and the accommodating space is an accommodating groove.
In this embodiment, the supporting member 40 is a retractable rod, and the accommodating space is the accommodating hole 31.
In this embodiment, the retractable rod is a pin shaft driven by hydraulic pressure, and a hydraulic driving part 41 is disposed at an end of the pin shaft and is fixedly disposed on the main deck.
