Description

Technical Field

[0001] This utility model relates to the field of marine crane technology, specifically to a marine crane base structure. Background Technology

[0002] With the development of the shipping industry, major shipping companies are paying increasing attention to the vessel's operational cycle, which consists of time spent at sea and time spent in port. To shorten dwell time, accelerate transportation cycles, and reduce operating costs, installing ship cranes for loading and unloading cargo can significantly improve lifting efficiency. However, existing ship crane bases are cumbersome to install and dismantle, and inconvenient to maintain; moreover, existing ship crane bases cannot be multi-purpose, requiring different bases for different specifications of ship cranes, a time-consuming and labor-intensive process that reduces work efficiency. Therefore, these problems urgently need to be solved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a marine crane base structure that facilitates the installation and disassembly of the marine crane base and makes maintenance convenient, thereby improving efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The innovative feature of this invention is that it includes a fixed base, a rotating mechanism, and a mounting base. The fixed base is a horizontally arranged circular structure, installed on the ship's deck via the rotating mechanism, and rotates horizontally around its own axis. Several rings of mounting holes with different outer diameters are vertically embedded in the lower surface of the fixed base along its circumference, and each mounting hole vertically penetrates the upper surface of the fixed base. The mounting base is a circular structure matching the marine crane, horizontally arranged, and ensures that the side connecting to the marine crane faces upwards. Internal threaded holes matching the mounting holes are vertically embedded in the lower surface of the mounting base along its circumference, and the position of each internal threaded hole corresponds to the position of the corresponding mounting hole. Driven by the rotating mechanism, the fixed base rotates horizontally to ensure that each internal threaded hole is coaxially aligned with the corresponding mounting hole, and then the mounting base is bolted to the fixed base.

[0005] Preferably, each of the internal threaded holes does not penetrate perpendicularly through the upper surface of the mounting base, and none of them interfere with the docking and installation of the marine crane and the mounting base.

[0006] Preferably, the upper surface of the mounting base is provided with symmetrical vertical lifting lugs near its edge, and each of the lifting lugs does not interfere with the docking and installation of the marine crane and the mounting base, thereby lifting the mounting base through the lifting lugs.

[0007] Preferably, the diameter of the mounting base matches the fixed end of the marine crane, and the diameter of the fixed base corresponds to the diameter of the mounting base that matches the largest marine crane, thereby ensuring that the fixed base meets the requirements of multiple uses.

[0008] Preferably, the rotating mechanism includes an upper top plate, a lower bottom plate, a cylinder, a rotating assembly, and a support column. Both the upper top plate and the lower bottom plate are horizontally arranged circular structures, parallel to each other vertically, with a rotating assembly between them. The rotating assembly drives the upper top plate to rotate horizontally around its own axis. A cylinder is also vertically and coaxially mounted on the lower surface of the lower bottom plate. The cylinder does not interfere with the installation of the lower bottom plate and the rotating assembly, and the lower bottom plate is fixedly mounted on the ship's deck via the cylinder. A cylindrical support column is also vertically and coaxially fixed on the upper surface of the upper top plate. The support column does not interfere with the installation of the upper top plate and the rotating assembly. The upper end face of the support column is coaxially and fixedly connected to the lower surface of the fixed base, and does not interfere with the screw connection between the mounting base and the fixed base. The support column also supports and fixes the fixed base.

[0009] Preferably, the rotary assembly includes a rotary ring, a rotary gear box, a motor, and a main gear. A rotary ring is horizontally parallel to the upper top plate and the lower bottom plate, and the rotary ring is coaxial with the lower bottom plate. The upper surface of the inner ring of the rotary ring is screwed to the upper top plate, and the lower surface of its outer ring is screwed to the lower bottom plate. A motor and a rotary gear box are vertically arranged on the upper surface of the upper top plate away from the rotary ring. The motor is linked to the rotary gear box and is screwed to the upper surface of the upper top plate via the rotary gear box. The output end of the rotary gear box extends vertically downwards from the lower surface of the upper top plate and meshes with the outer ring of the rotary ring via the main gear. Driven by the motor, the upper top plate rotates horizontally through the meshing of the main gear and the rotary ring, causing the fixed base to rotate around its own axis.

[0010] Preferably, the diameter of the lower base plate is greater than the outer diameter of the swivel ring and less than the diameter of the upper top plate; the diameter of the upper top plate is greater than the outer diameter of the swivel ring and corresponds to the diameter of the fixed base.

[0011] Preferably, the motor and the rotary gearbox are both spaced apart on the outside of the support column, and the height of the support column must ensure that the fixed base is spaced above the motor.

[0012] Preferably, several protective plates are evenly distributed and sleeved along the circumferential direction on the outer circumferential surface of the fixed base, and each of the protective plates is an arc-shaped structure that matches the fixed base; the upper end of each protective plate is flush with the upper surface of the fixed base and is screwed to the corresponding position of the outer circumferential surface of the fixed base, thereby splicing them into a circular structure and being sleeved and fixed to the fixed base coaxially; the lower end of each protective plate extends vertically downward to the position near the lower bottom plate and is screwed to the corresponding position of the outer circumferential surface of the upper top plate, and is set without interfering with the rotating assembly, thereby protecting the rotating assembly through the protective plates.

[0022] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0023] This utility model discloses a marine crane base structure, including a fixed base 9, a rotating mechanism, and a mounting base 10; the specific structure is as follows: Figure 1 , Figure 2 As shown, the fixed base 9 is a horizontally arranged circular structure, installed on the ship's deck via a rotating mechanism, and rotates horizontally around its own axis. Several rings of mounting holes 11 with different outer diameters are vertically embedded in the lower surface of the fixed base 9 along its circumference, and each mounting hole 11 vertically penetrates the upper surface of the fixed base 9. The mounting seat 10 is a circular structure matching the marine crane, horizontally arranged, ensuring that the side connecting to the marine crane faces upwards. Internal threaded holes matching the mounting holes 11 are vertically embedded in the lower surface of the mounting seat 10 along its circumference, and the position of each internal threaded hole corresponds to the position of the corresponding mounting hole 11. Each internal threaded hole does not vertically penetrate the upper surface of the mounting seat 10 and does not interfere with the docking installation of the marine crane and the mounting seat 10. Driven by the rotating mechanism, the fixed base 9 rotates horizontally to ensure that each internal threaded hole is coaxially aligned with the corresponding mounting hole 11, and then the mounting seat 10 is bolted to the fixed base 9.

[0024] like Figure 1 As shown, the diameter of the mounting base 10 matches the fixed end of the marine crane, and the diameter of the fixed base 9 corresponds to the diameter of the mounting base 10 that matches the largest marine crane, thus ensuring that the fixed base 9 meets the requirements of one type for multiple uses; on the upper surface of the mounting base 10, there are also symmetrical vertical lifting lugs 12 near its edge, and each lifting lug 12 does not interfere with the docking and installation of the marine crane and the mounting base 10, so that the mounting base 10 can be lifted by the lifting lug 12.

[0025] The rotating mechanism of this utility model includes an upper top plate 4, a lower bottom plate 2, a cylinder 1, a rotating assembly, and a support column 8; as shown... Figure 1As shown, both the upper top plate 4 and the lower bottom plate 2 are horizontally arranged circular structures, and they are arranged parallel to each other vertically. A rotating assembly is provided between them, which drives the upper top plate 4 to rotate horizontally around its own axis. A cylindrical body 1 is also vertically and coaxially arranged on the lower surface of the lower bottom plate 2. The cylindrical body 1 does not interfere with the installation of the lower bottom plate 2 and the rotating assembly, and the lower bottom plate 2 is fixedly installed on the ship deck through the cylindrical body 1. A cylindrical support column 8 is also vertically and coaxially fixed on the upper surface of the upper top plate 4, and the support column 8 does not interfere with the installation of the upper top plate 4 and the rotating assembly. The upper end face of the support column 8 is coaxially and fixedly connected to the lower surface of the fixed base 9, and does not interfere with the screw connection between the mounting base 10 and the fixed base 9. The support column 8 supports and fixes the fixed base 9.

[0026] The rotary assembly of this utility model includes a rotary ring 3, a rotary gearbox 5, a motor 7, and a main gear 6; as shown... Figure 1 As shown, a rotating ring 3 is horizontally parallel to the upper top plate 4 and the lower bottom plate 2, and the rotating ring 3 is coaxial with the lower bottom plate 2. The upper surface of the inner ring of the rotating ring 3 is screwed to the upper top plate 4, and the lower surface of its outer ring is screwed to the lower bottom plate 2. A motor 7 and a rotary gear box 5 are vertically installed on the upper surface of the upper top plate 4 away from the rotating ring 3. The motor 7 and the rotary gear box 5 are linked and connected, and the rotary gear box 5 is screwed to the upper surface of the upper top plate 4. The output end of the rotary gear box 5 extends vertically downward from the lower surface of the upper top plate 4 and is meshed with the outer ring of the rotating ring 3 through the main gear 6. The diameter of the lower bottom plate 2 is larger than the outer diameter of the rotating ring 3 and smaller than the diameter of the upper top plate 4; the diameter of the upper top plate 4 is larger than the outer diameter of the rotating ring 3 and corresponds to the diameter of the fixed base 9. Driven by the motor 7, the upper top plate 4 rotates horizontally through the meshing of the main gear 6 and the rotary ring 3, which in turn drives the fixed base 9 to rotate around its own axis.

[0027] like Figure 1 As shown, the motor 7 and the rotary gear box 5 are both spaced apart on the outside of the support column 8, and the height of the support column 8 must ensure that the fixed base 9 is spaced apart above the motor 7.

[0028] This utility model also includes several protective plates 13 evenly distributed and sleeved along the circumferential direction on the outer circumferential surface of the fixed base 9, and each protective plate 13 is an arc-shaped structure that matches the fixed base 9; for example Figure 1 , Figure 2As shown, the upper end of each protective plate 13 is flush with the upper surface of the fixed base 9, and is screwed to the corresponding position of the outer circumference of the fixed base 9, thus forming a circular structure and being coaxially sleeved and fixed with the fixed base 9; the lower end of each protective plate 13 extends vertically downward to the position near the lower bottom plate 2, and is screwed to the corresponding position of the outer circumference of the upper top plate 4, and is set without interfering with the rotating assembly, thus protecting the rotating assembly through the protective plate 13.

[0029] The working principle of this utility model is as follows: First, each protective plate 13 is coaxially sleeved onto the fixed base 9 and screwed to the fixed base 9 and the upper top plate 4 respectively; then, a matching mounting base 10 is selected according to the specifications of the marine crane, and the corresponding mounting base 10 is horizontally lifted to the top of the fixed base 9 through the lifting lug 12, ensuring that the mounting base 10 and the fixed base 9 are coaxial vertically; then, driven by the rotating mechanism, the fixed base 9 rotates horizontally to ensure that each internal thread hole is coaxially aligned with the corresponding mounting hole 11, and then the mounting base 10 is screwed to the fixed base 9 with bolts; then, driven by the rotating mechanism, the mounting base 10 rotates horizontally to adjust its position, at which point the marine crane can be connected and installed with the mounting base 10.
