Description

Technical Field

[0001] This utility model relates to the technical field of ship cargo securing devices, and more specifically, to an adaptively adjustable ship cargo securing device. Background Technology

[0002] In the modern shipping system, short-haul maritime transport plays an important role in regional economic exchange and inter-port material allocation due to its flexibility, efficiency and rapid turnover. Compared with long-haul maritime transport, short-haul maritime transport has significant characteristics such as frequent voyages, intensive loading and unloading operations, and diverse types of goods in smaller batches. It undertakes the task of rapid transportation of fresh agricultural products, manufactured goods and building materials between cities, and is a key link in ensuring the stability of regional supply chains and promoting the coordinated development of coastal economies.

[0003] However, the cargo securing process in current short-haul maritime transport faces numerous challenges. Traditional cargo securing methods, such as using rope binding or simple metal clips, have drawbacks. For example, traditional securing components lack versatility for storage container structures of different sizes (e.g., 20-foot, 40-foot, 45-foot) and types (dry cargo containers, refrigerated containers, open-top containers, etc.). This necessitates frequent replacement of securing components, such as clips and ropes, depending on the container type and specifications. The entire process is cumbersome and inefficient, hindering adaptive adjustment for different sizes and types, and impacting ease of use. Therefore, we propose an adaptive adjustable ship cargo securing device. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution: an adaptive adjustable ship cargo fixing device, including multiple detachable columns 1 installed on the ship deck, with a fixing base 11 fixedly installed at the bottom of the column 1. The fixing base 11 is detachably installed on the ship deck by multiple fastening bolts, so that the fixing device can flexibly adjust the installation position according to the cargo layout to meet the fixing requirements of containers of different sizes and quantities.

[0034] In this embodiment, a protective cylinder 12 is fixedly installed at the top of the column 1. A top cover 13 is detachably installed on the top surface of the protective cylinder 12. A column shaft 2 is rotatably connected inside the protective cylinder 12. The column shaft 2 passes through the top cover 13 and is rotatably connected to the top cover 13. The column shaft 2 rotates through the meshing of a drive motor 21 and a gear. A support plate 22 is fixedly installed at the top of the column shaft 2. A driven gear 20 is fixedly installed on the shaft of the column shaft 2 located inside the protective cylinder 12. A drive gear 211 is fixedly installed at the end of the output shaft of the drive motor 21. The drive gear 211 and the driven gear 20 mesh with each other, enabling the column shaft 2 to rotate stably and accurately, driving the support plate 22 to adjust the angle. This achieves the function of adaptive adjustment according to the placement angle of the container, solving the problem that traditional fixing methods are difficult to adapt to goods at different angles, and achieving the effect of improving the stability and fit of the goods.

[0035] Specifically, a first hydraulic cylinder 24 is fixedly installed on the top surface of the support plate 22, which realizes the function of adjusting the support height according to the height of the container. A support base plate 25 is detachably installed at the end of the telescopic shaft of the first hydraulic cylinder 24. A second hydraulic cylinder 26 is fixedly installed on the upper surface of the support base plate 25. A clamping and fixing plate 261 for clamping and fixing the container is fixedly installed at the end of the telescopic shaft of the second hydraulic cylinder 26. It can effectively clamp and fix containers of different heights and sizes, solve the problem of poor universality of traditional fixing methods, and achieve the effect of meeting the diversified fixing needs of short-distance maritime transport.

[0036] like Figure 1 As shown, column 1 has a hollow structure, and a cable outlet hole 10 is provided on the bottom cylinder of column 1, which allows the wiring of the device to be arranged inside column 1, effectively protecting the wiring, and facilitating wiring operations. This achieves the convenience of wiring installation and protection, and improves the safety and reliability of the device's electrical system.

[0037] like Figure 1 As shown, the plane of the bottom wall of column 1 is inclined downward at 30 to 60 degrees toward the outlet hole 10, so that seawater can be quickly discharged along the inclined bottom wall and outlet hole 10, and is less likely to enter the outlet hole 10 and leave residue, thus protecting the internal circuit.

[0038] like Figure 2 As shown, a mechanical seal 14 is fixedly installed on the top surface of the top cover 13. The column shaft 2 passes through the mechanical seal 14 and is rotatably connected to the mechanical seal 14, so that the connection between the column shaft 2 and the top cover 13 is effectively sealed, preventing seawater, dust and other substances from entering the interior of the protective cylinder 12, protecting the internal transmission components, and realizing the function of enhancing the sealing and protection of the device, thereby ensuring the normal operation of the column shaft 2 and other components and extending the service life of the device.

[0039] like Figure 3 As shown, a crash barrier 23 is fixedly installed on the top surface of the support plate 22, which is fitted around the first hydraulic cylinder 24. The top of the crash barrier 23 is connected to the outside, which can effectively buffer the impact force of external collisions on the first hydraulic cylinder 24 and prevent it from being damaged by the collision. This realizes the crash protection function of the first hydraulic cylinder 24, and achieves the effect of ensuring the normal operation of the hydraulic cylinder and improving the reliability of the device.

[0040] like Figure 4 As shown, a steel plate 241 is fixedly installed at the end of the telescopic shaft of the first hydraulic cylinder 24. The support base plate 25 is fixedly installed on the steel plate 241 by multiple fastening bolts, which enhances the stability of the connection between the support base plate 25 and the first hydraulic cylinder 24, enabling the support base plate 25 to withstand greater loads. This achieves the effect of improving the structural strength and load-bearing capacity of the device, and ensures the reliability of cargo fixation.

[0041] like Figure 5 As shown, a protective shell 27 is detachably installed on the upper surface of the support base plate 25. The protective shell 27 protects the second hydraulic cylinder 26 inside, preventing damage to the second hydraulic cylinder 26 from seawater, cargo collisions, etc., while facilitating the inspection and maintenance of the second hydraulic cylinder 26.

[0042] like Figure 6 As shown, a drainage hole 251 is provided on the support base plate 25. The top opening of the drainage hole 251 is located on the top surface of the support base plate 25, and the bottom opening of the drainage hole 251 is located on the side of the support base plate 25. This allows water to be drained in time after entering the support base plate 25, preventing water accumulation from corroding the components. This effectively protects the second hydraulic cylinder 26 and provides drainage, thereby extending the service life of the hydraulic cylinder and ensuring the normal operation of the device.

[0043] It is worth noting that, in practical use, the position of the column 1 can be flexibly adjusted according to the size of the goods, and the height and extension length of the clamping and fixing plate 261 can also be adjusted, so that the clamping and fixing plate 261 can clamp and fix goods of various sizes, achieving an adaptive adjustment effect. It should also be noted that the drive motor 21, the first hydraulic cylinder 24, the second hydraulic cylinder 26, the corresponding control system, and the external power supply of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0044] In addition, a pressure sensor can be installed on one side of the cargo clamping plate 261. The ship has a built-in control unit that receives the data transmitted by the pressure sensor, analyzes and processes it using a built-in adaptive control algorithm, calculates the adjustment parameters required to maintain the stability of the container, and further controls the corresponding actions of the drive motor 21 and the hydraulic cylinder. This control system is a conventional technology and will not be described in detail here.

[0045] When using the adaptive adjustment ship cargo fixing device of this utility model, firstly, according to the cargo layout and ship deck structure, the fixing base 11 at the bottom of the column 1 is installed at the designated position on the ship deck using fastening bolts to complete the basic fixing of the device.

[0046] When loading the container, the drive motor 21 is started, and the drive gear 211 and the driven gear 20 mesh to drive the column shaft 2 to rotate, so that the support plate 22 is adjusted to a suitable angle. Then, according to the height of the container, the telescopic shaft of the first hydraulic cylinder 24 is adjusted to drive the support base plate 25 to rise or fall to the corresponding height. Subsequently, the second hydraulic cylinder 26 is started to extend the clamping and fixing plate 261 and clamp the container, so as to achieve a stable fixation of the container.

[0047] If the position or angle of the container changes due to wind and waves during the ship's navigation, the drive motor 21 and hydraulic cylinder can be restarted to adaptively adjust the angle of the column shaft 2, the support height and the clamping force to ensure that the cargo is fixed and stable.

[0048] When unloading cargo, first operate the second hydraulic cylinder 26 to release the clamping plate 261 from the container, then adjust the first hydraulic cylinder 24 to lower the height of the support base plate 25. After the container is lifted away, reset all components of the device.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
