Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This embodiment provides a vertical salvage device based on a catamaran, such as... Figure 1 and Figure 2 As shown, the system is located in the moon pool position of the catamaran 1, including a support assembly 2 and a multi-directional adjustable lifting and salvage assembly 3; the multi-directional adjustable lifting and salvage assembly 3 is located below the support assembly 2 and is connected to the catamaran 1 through the support assembly 2.

[0026] Specifically, the multi-directional adjustable lifting and salvage assembly 3 includes a lifting component 31, a salvage platform 32, and a multi-directional adjustment component 33 for multi-directional adjustment of the position of the salvage platform; one end of the lifting component 31 is connected to the support assembly 2, and the other end is connected to the multi-directional adjustment component 33 of the salvage platform.

[0027] The salvage platform 32 is mounted on the multi-directional adjustment component 33 of the salvage platform and can move in multiple directions under the control of the multi-directional adjustment component 33. The end face of the salvage platform 32 away from the multi-directional adjustment component 33 is provided with a target position adjustment component 34.

[0028] Specifically, a heavy-load target salvage device is installed on the large moon pool created on the catamaran. The moon pool is located between the bridge and the aft deck. Since the moon pool is close to the catamaran's center of gravity, placing the salvage device in the moon pool reduces the impact of the heavy-load target on the catamaran's balance. During the salvage process, the position of the salvage platform 32 is flexibly adjusted in real time by the multi-directional adjustment component 33, reducing the impact of ship movement on the salvage operation, ensuring the salvage platform vertically retrieves the object, and improving the comfort, stability, and safety of the salvage operation.

[0029] Specifically, in this embodiment, the salvage platform 32 is a square structure, and the panel of the salvage platform that contacts the target object is a mesh structure (not shown in the figure), ensuring flexible contact between the salvage platform and the target object during salvage and avoiding damage to the target object. Meanwhile, reinforcing ribs are provided at the bottom of the salvage platform to enhance its load-bearing strength and meet the requirements for salvaging heavy objects.

[0030] In a specific embodiment, the multi-directional adjustment component 33 of the salvage platform includes a base 331 and a plurality of adjustment units 332; one end of the plurality of adjustment units is disposed at the edge of the base 331, and the other end is connected to the salvage platform 32.

[0031] Specifically, in this embodiment, preferably, three adjustment units 332 are provided, which are respectively arranged on the outer frame. The position of the salvage platform 32 is adjusted by the cooperation of the three adjustment units 332 to ensure that the object or person is always salvaged vertically.

[0032] In a specific embodiment, the adjustment unit 332 includes a mounting base and a hydraulic rod, one end of which is movably connected to the mounting base and the other end is fixedly connected to the salvage platform 32.

[0033] Specifically, the target position adjustment component 34 includes several target adjustment units, which are evenly arranged at the edge of the salvage platform 32 and all inclined towards the center of the salvage platform 32. Specifically, in this embodiment, preferably, four target adjustment units are provided to ensure smooth adjustment of the target position and fixation of the target after adjustment.

[0034] Specifically, each target adjustment unit includes an adjustment boom, an adjustment arm, and a hydraulic cylinder, and is fixedly installed at the edge of the salvage platform 32 via the adjustment boom. The adjustment boom, adjustment arm, and hydraulic cylinder are movably connected in pairs via rotating shafts. When the position of the target needs to be adjusted, each hydraulic cylinder performs a corresponding extension and retraction movement, thereby driving the adjustment arm to move closer to or away from the target to adjust the position of the target on the salvage platform.

[0035] Specifically, in this embodiment, preferably, the end of the adjusting forearm that contacts the salvaged object is designed with an arc shape, thereby increasing the contact area with the salvaged object and facilitating the adjustment and fixation of the salvaged object. In practice, the end of the adjusting forearm that contacts the salvaged object can also be adapted to the shape of the salvaged object for ease of operation. Furthermore, a flexible material structure, such as rubber, can be provided at the end of the adjusting forearm that contacts the salvaged object to prevent damage to the salvaged object.

[0036] In a specific embodiment, the base 331 includes an outer frame and an inner fixing frame for supporting the outer frame; the inner fixing frame is disposed inside the outer frame, and one end of a plurality of the adjustment units 332 is disposed on the outer frame.

[0037] Specifically, in this embodiment, both the outer frame and the inner fixing frame used to support the outer frame are square structures, and the end corners of the inner fixing frame are respectively set at the four sides of the outer frame, thereby playing a supporting role for the outer frame, ensuring the structural stability of the outer frame, and ensuring the smooth progress of the salvage process.

[0038] In a specific embodiment, a vertical salvage device based on a catamaran also includes a limiting component 4, one end of which is connected to the catamaran 1 and the other end is connected to the multi-directional adjustment component 33 of the salvage platform.

[0039] The limiting component 4 includes a sliding column 41 and a slide rail 42. One end of the sliding column 41 is slidably connected to the slide rail 42, and the other end is connected to the multi-directional adjustment component 33 of the salvage platform. The slide rail 42 is close to the outer wall of the catamaran and connected to the catamaran 1.

[0040] Specifically, the setting of the limiting component 4 can prevent the salvage device from swaying in the horizontal direction, improve the salvage device's resistance to wind and waves, and at the same time limit the movement of the lifting component 31, ensuring the smooth progress of the salvage process.

[0041] In a specific embodiment, the edge of the salvage platform 32 is also provided with a guide plate and several protective plates (not shown in the figure); the guide plate includes a first guide plate and a second guide plate, one end of the first guide plate and one end of the second guide plate are both located at the edge of the salvage platform 32, and the other end of both point towards the bow of the catamaran; the several protective plates are all inclined towards the center of the salvage platform 32.

[0042] Specifically, in this embodiment, guide plates and protective plates are respectively set at different edge positions of the salvage platform. The guide plates guide the target object to smoothly enter the salvage platform 32. The protective plates set near the sides of the hull prevent the target object from swaying and hitting the hull. The protective plates set opposite the guide plates prevent the salvaged object from deviating from the salvage platform. At the same time, a flexible material structure, such as rubber, is set at the end of the protective plate that contacts the salvaged object to avoid scratching the target object.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
