In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] like Figure 1 and Figure 2As shown, the utility model provides a gantry crane type semi-submersible salvage crane vessel, which includes a hull 1, a connecting bridge 2 and a gantry crane 3. The hull 1 includes a first hull 11 and a second hull 12; the connecting bridge 2 is straddled between the first hull 11 and the second hull 12, and a maintenance platform is arranged on the connecting bridge 2, and the maintenance platform is used to inspect the salvaged object 100; a first stern door 111 is arranged on the first hull 11, and a second stern door 121 is arranged on the second hull 12, and the first stern door 111 and the second stern door 121 can move toward each other to enclose a salvage area 5 between the first hull 11, the second hull 12 and the connecting bridge 2; the gantry crane 3 is movably straddled between the first hull 11 and the second hull 12 along a first direction, and the gantry crane 3 is used to lift and carry the salvaged object 100 from the salvage area 5. In this embodiment, the hull 1 includes a first hull 11 and a second hull 12, and the connecting bridge 2 is arranged across the first hull 11 and the second hull 12, so the gantry crane type semi-submersible salvage crane ship is a catamaran structure, which greatly improves the stability of the gantry crane type semi-submersible salvage crane ship and reduces the impact of wind and waves on the salvage operation of the sunken ship; because the first hull 11 and the second hull 12 are respectively provided with a first stern door 111 and a second stern door 121, the first stern door 111 and the second stern door 121 can move toward each other so as to enclose the first hull 11, the second hull 12 and the connecting bridge 2 to form a The salvage area 5 is relatively isolated from the external water surface to form a still water area, which prevents water waves from impacting the salvaged object 100 and causing salvage difficulties, thereby ensuring the smooth progress of the internal salvage operation; since the gantry crane 3 is movably arranged on the first hull 11 and the second hull 12 along the first direction, the gantry crane 3 can lift the salvaged object 100 from above the salvage area 5 to the maintenance platform along the first direction. The maintenance platform is used for emergency maintenance of the salvaged object with binding and fixing agents. It is easy to operate and does not require manual use of other mechanical equipment to move it again, thereby improving the efficiency of the salvage operation. Specifically, the connecting bridge 2 is arranged at the bow of the hull 1, and the middle section and stern of the hull 1 are enclosed with the closed first stern door 111 and the second stern door 121 to form the salvage area 5, so that the gantry crane 3 can smoothly lift the salvaged object 100 without being affected by external water waves.

[0036] Furthermore, the hull 1 can move between a submerged position and a floating position in the water; in the submerged position, the first hull 11 and the second hull 12 are submerged below the water surface, and the connecting bridge 2 is submerged in the water; in the floating position, the first hull 11 and the second hull 12 are surfaced, and the connecting bridge 2 is located above the water surface. In this embodiment, the gantry crane type semi-submerged salvage crane is a semi-submerged ship, and the hull 1 can move between a submerged position and a floating position; when the gantry crane type semi-submerged salvage crane moves to the water area where the salvaged object 100 is located, the hull 1 first sinks to the submerged position, and the gantry crane 3 is used to connect with the salvaged object 100; then, when the gantry crane 3 is used to lift the salvaged object 100 upward, the hull 1 can be discharged from the submerged position and floated to the floating position, so that the salvaged object 100 can be salvaged from the water under the action of buoyancy, which greatly reduces the load of the gantry crane 3, thereby improving the salvage capacity of the gantry crane type semi-submerged crane. Specifically, a semi-submersible vessel is a type of ship commonly used in water transportation. It can adjust its own ballast water volume to achieve the sinking and floating of the cargo deck, thereby achieving the purpose of lifting and carrying. Its specific working principle will not be elaborated here.

[0037] Furthermore, the first hull 11 and the second hull 12 of the gantry crane 3 are both provided with running grooves along the first direction, and the gantry crane 3 has running wheels matching the running grooves, and the running wheels roll in cooperation with the running grooves. Specifically, the two side legs of the gantry crane 3 roll in the running grooves on the first hull 11 and the second hull 12 respectively through steerable tire-type running wheels, and the running wheels are controlled by motors, and the staff can control the rolling and braking of the running wheels according to the needs of salvage; the gantry crane 3 moves on the hull 1 through the running wheels, which improves the maneuverability and reduces the difficulty of movement.

[0038] Furthermore, if Figure 2 As shown, the first hull 11 and the second hull 12 are both provided with a limit device 4, and the limit device 4 includes a stopper assembly 41 arranged on both sides of the legs of the gantry crane 3 along the first direction, and the stopper assembly 41 is in contact with and slidably cooperates with the legs of the gantry crane 3. In this embodiment, the stopper assembly 41 is fixed on the first hull 11 and the second hull 12 respectively, and the stopper assembly 41 is arranged on both sides of the legs of the gantry crane 3, so as to form a lateral limit on the legs, and prevent the gantry crane 3 from capsizing when the hull 1 is shaken by the influence of wind and waves, thereby ensuring the safety of the salvage operation.

[0039] Specifically, Figure 2As shown, a limit block 42 is provided on the leg of the gantry crane 3, and a limit groove is provided on the stop assembly 41 corresponding to the limit block 42, and the limit block 42 slides and cooperates with the limit groove along the first direction. In this embodiment, limit blocks 42 are provided on both sides of the legs of the gantry crane 3, and limit grooves are provided on the stop assemblies 41 on both sides, and the limit blocks 42 can slide in the limit grooves along the first direction; through the cooperation between the limit blocks 42 and the limit grooves, the gantry crane 3 can be prevented from vertically separating from the travel groove, so that the gantry crane 3 can only move on the travel groove along the first direction, thereby further improving the stability of the gantry crane 3 in the process of lifting the salvaged object 100.

[0040] Specifically, Figure 2 As shown, there are multiple limit blocks 42 and limit grooves, and the limit grooves are slidably matched with the limit blocks 42. In this embodiment, the multiple limit blocks 42 are slidably matched with the multiple limit grooves in a one-to-one correspondence, which greatly improves the stability and safety of the gantry crane 3 during operation.

[0041] Specifically, the limit block 42 is covered with a flexible pad. In this embodiment, the flexible pad is made of a flexible material such as rubber or sponge, and the flexible pad can absorb extrusion and impact by deforming to avoid rigid extrusion between the limit block 42 and the limit groove to damage the stop assembly 41.

[0042] Specifically, the limit device 4 also includes a lubricating component, which is used to spray lubricant into the limit block 42 and the limit groove. In this embodiment, the lubricant can be water or lubricating oil according to the actual situation on site to reduce the sliding friction between the limit block 42 and the limit groove, thereby improving the smoothness of the operation of the gantry crane 3.

[0043] Specifically, Figure 2 As shown, the stop assembly 41 includes a retaining wall 411 and a retaining frame 412 stacked from low to high in the height direction. In this embodiment, the retaining wall 411 is welded from steel plates, the retaining wall 411 is fixed on the first hull 11 or the second hull 12, and the retaining wall 411 is welded with a retaining frame 412 along the vertical upper side. The retaining frame 412 is a truss structure welded from a steel frame. Compared with the retaining wall 411, the retaining frame 412 consumes less steel and is lighter in weight, thereby reducing the production cost of the stop assembly 41, and also reducing the weight of the stop assembly 41, which is convenient for disassembly, assembly and transportation; by stacking the retaining wall 411 and the retaining frame 412, the effective position limit of the gantry crane 3 is achieved, and the loss of steel is reduced and the overall weight is reduced.

[0044] Furthermore, if Figure 1 and Figure 2As shown, the first hull 11 and the second hull 12 are both provided with elastic buffer pads 112 on the side facing the salvage area 5. In this embodiment, the elastic buffer pads 112 are made of rubber, which can prevent the gantry crane 3 from colliding with the hull 1 when lifting the salvaged object 100 and damaging the salvaged object 100 or the hull 1, thereby effectively protecting the hull 1.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
