[0024] A Pure Car and Truck Carrier (PCTC) is a vessel designed specifically for transporting cars and trucks. These vessels are typically equipped with a lifting deck (a characteristic of Ro-Ro vessels) to facilitate loading and unloading of vehicles.
[0025] The lifting deck of a PCTC vessel is a thin plate structure, generally 6mm thick, and the individual decks are relatively large. Existing technology typically involves welding hoists to the deck for lifting. External lifting equipment connects to the deck's lifting hooks, which then lift the deck along with it. This process can easily cause deck deformation, and the welded lifting hooks must be removed after the lifting is complete.
[0026] In order to reduce the damage to the parent material caused by welding the lifting horse and subsequent cutting in the traditional lifting method, the present application provides a lifting device for the lifting deck of a PCTC ship.
[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.
[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.
[0029] The following is combined with Figure 1-6 This application is described in further detail.
[0030] The embodiment of the present application discloses a PCTC ship lifting deck hoisting device. Figure 1 、 Figure 2A PCTC ship deck hoisting device includes a horizontally arranged hoisting frame 1. A hoisting assembly 2 is fixedly connected to the upper surface of the hoisting frame 1. The hoisting assembly 2 is used to hoist the hoisting frame 1 using external hoisting equipment. Multiple hoisting connectors 3 are located below the hoisting frame 1. The hoisting connectors 3 are used to connect to lashing holes on the deck, thereby connecting the deck to the hoisting frame 1. A leveling assembly 4 is located between the hoisting frame 1 and the hoisting connectors 3. The leveling assembly 4 can adjust the height of the multiple hoisting connectors 3, thereby adjusting the level of the deck hoisted below.
[0031] The hanging frame 1 includes two horizontally arranged crossbeams 11, two crossbeams 11 are arranged in parallel with each other, and the ends of the two crossbeams 11 are fixedly connected to longitudinal beams 12, which are arranged horizontally and perpendicular to the crossbeams 11. The oppositely arranged crossbeams 11 and longitudinal beams 12 form a rectangular frame structure.
[0032] An auxiliary crossbeam 13 is provided between the two opposing crossbeams 11. The auxiliary crossbeam 13 is arranged parallel to the crossbeam 11, and both ends of the auxiliary crossbeam 13 are fixedly connected to the longitudinal beam 12. An auxiliary longitudinal beam 14 is provided between the two opposing longitudinal beams 12. The auxiliary longitudinal beam 14 is arranged parallel to the longitudinal beam 12, and both ends of the auxiliary longitudinal beam 14 are fixedly connected to the crossbeam 11.
