Description

Technical Field

[0001] This application relates to the field of container securing devices, and in particular to a marine container lashing device. Background Technology

[0002] Marine container lashing devices are connection and tensioning securing equipment used in the field of marine container transportation. They are typically used to secure containers stacked on the deck or in the hold of a ship. By connecting the lashing device between the container's lashing point and the ship's anchoring point, and by adjusting and locking the length of the lashing device, the container can remain stable during navigation. This reduces the risk of containers shifting, tilting, or even falling off their stacking position due to the ship's rolling, vibration, turbulence, and the impact of wind and waves, playing a vital role in ensuring the safety of marine transportation.

[0003] Existing marine container lashing devices typically include a basket body and pull rods at both ends of the basket body. Each end of the basket body has threaded holes, and the pull rods, being threaded rods, pass through the corresponding threaded holes to achieve a threaded connection between the basket body and the pull rods. In actual use, the operator rotates the basket body or the pull rods to extend or retract the pull rods relative to the basket body, thereby adjusting the overall length of the lashing device and placing it in a tensioned state to secure the container.

[0004] While the aforementioned structure can meet the basic connection and tensioning requirements of marine container lashing devices, under marine transportation conditions, the lashing devices not only require frequent installation, disassembly, and length adjustment, but also endure significant axial tensile forces, alternating loads, and vibration loads from hull rolling and wave impacts over extended periods. Because the threaded connection between the tie rod and the basket body is directly located at the end of the basket body, the tie rod continuously rubs and compresses against the threaded hole at the end of the basket body during repeated screwing in and out, and during prolonged stress. This can easily lead to wear, stripping, or even failure of the threaded hole at the end of the basket body.

[0005] Furthermore, the basket body is typically a primary load-bearing component in marine container lashing devices. In existing technologies, the threaded holes are directly formed within the basket body itself, meaning the basket body simultaneously bears both overall load-bearing capacity and threaded connection functions. If the threaded holes at the end of the basket body are damaged, the entire basket body often needs repair or replacement. This is not only inconvenient to repair but also increases usage and maintenance costs, hindering the long-term reusability of the marine lashing device.

[0006] Therefore, how to improve the convenience of maintenance and reduce the use and maintenance costs of marine container lashing devices while ensuring reliable connection and length adjustment, thereby facilitating their long-term reuse, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] To improve the convenience of maintenance, reduce the cost of using and maintaining marine lashing devices, and thus facilitate the long-term reuse of marine lashing devices, this application provides a marine container lashing device.

[0008] The technical solution for a marine container lashing device provided in this application is as follows: A marine container lashing device includes a basket body, a first connecting mechanism, and a second connecting mechanism, wherein the first connecting mechanism and the second connecting mechanism are respectively disposed at both ends of the basket body; The flower basket body includes a pole, and a first end and a second end that are respectively connected to the two ends of the pole; The first connecting mechanism includes a first pull rod and a fork head, wherein the first pull rod is a screw rod and the fork head is fixedly disposed at one end of the first pull rod; A threaded seat is detachably installed on the flower basket body, and the threaded seat is slidably connected to the flower basket body. The threaded seat is provided with a threaded through hole that cooperates with the first pull rod. The first pull rod is threadedly connected to the threaded seat so as to realize the connection and length adjustment between the first pull rod and the flower basket body through the threaded seat. The second connecting mechanism is connected to the rod part through the second end.

[0009] By adopting the above technical solution, the threaded connection structure, which was originally directly supported by the end of the basket body, is replaced by a threaded seat that is detachable and slidably mounted on the basket body. This separates the threaded connection structure from the load-bearing structure of the basket body, reducing thread wear and extending the service life of the basket body. At the same time, when the threaded connection wears out, it can be repaired by replacing the threaded seat, thereby reducing maintenance costs and improving the stress state of the connection, connection stability, and assembly adaptability.

[0010] Preferably, a mounting through hole is provided on the first end, and the first pull rod passes through the mounting through hole.

[0011] By adopting the above technical solution, by setting an installation through hole on the first end for the first pull rod to pass through, a guiding fit is formed between the first pull rod and the basket body, which helps to ensure the movement stability of the first pull rod when it is extended and retracted relative to the basket body, and provides a fit basis for the threaded fit between the threaded seat and the first pull rod.

[0012] Preferably, there are two rods, and the threaded seat is provided with a groove that matches the rod. The groove is a semi-open groove so that the threaded seat can slide along the length of the rod and can restrict the rotation of the threaded seat relative to the basket body.

[0013] By adopting the above technical solution, and by setting two rods and a semi-open groove that matches the rods, the threaded seat can slide along the length of the rods and be limited by the circumferential direction of the rods, thus preventing the threaded seat from rotating during the adjustment process. This helps to improve the smoothness and reliability of the thread adjustment between the first pull rod and the threaded seat.

[0014] Preferably, a limiting member is fitted on both of the rods. The end of the first pull rod is provided with a limiting block. The limiting member is provided with a limiting hole that matches the cross-sectional shape of the limiting block. When the first pull rod is adjusted to a predetermined position, the limiting block is inserted into the limiting hole to restrict the relative rotation between the first pull rod and the flower basket body.

[0015] By adopting the above technical solution, and by setting a limiting component, a limiting block, and a limiting hole, after the first pull rod is adjusted to the predetermined position, the relative rotation between the first pull rod and the basket body can be limited by inserting the limiting block into the limiting hole, thereby achieving the anti-loosening function and improving the locking reliability of the lashing device under ship vibration and swaying conditions.

[0016] Preferably, the second connecting mechanism includes a second pull rod and a hook, the second pull rod is disposed at the second end and is tunably connected to the flower basket body, and the pull rod is connected to the container through the hook.

[0017] By adopting the above technical solution, the second connecting mechanism is configured to include a second pull rod and a hook, and the second pull rod is located at the second end and is adjustablely connected to the flower basket body, so that the other end of the tie-down can be easily connected to the container, and the overall length adjustment and tensioning can be achieved in conjunction with the first connecting mechanism.

[0018] Preferably, the second pull rod is provided with a plurality of connecting blocks spaced apart along its length, and the second end is provided with a blocking groove. The connecting blocks can be selectively inserted into the blocking groove to adjust the extension length of the second pull rod relative to the flower basket body.

[0019] By adopting the above technical solution, by setting multiple connecting blocks on the second tie rod and setting a blocking groove on the second end, the second tie rod can achieve segmented length adjustment, which facilitates the quick selection of the appropriate extension length according to different binding conditions and improves the convenience of on-site adjustment.

[0020] Preferably, a connecting seat is fixedly provided at the end of the second pull rod, and a connecting hole is provided on the connecting seat. One end of the hook is a hook-shaped structure, and the other end passes through the connecting hole. The hook is rotatably connected to the connecting seat so that the angle of the hook can be adjusted. A blocking part is provided at the end of the hook that passes through the connecting hole to prevent the hook from detaching from the connecting seat.

[0021] By adopting the above technical solution, and by setting a connecting seat, a connecting hole, and a rotatable hook, the angle of the hook can be automatically or actively adjusted, thereby improving its attitude adaptability with external connection points; at the same time, by using a blocking part to prevent the hook from detaching from the connecting seat, it is beneficial to improve the connection reliability.

[0022] Preferably, the limiting member includes a limiting base, an adjusting body, and a fixing member. The limiting base is connected to the rod portion, the limiting hole is disposed on the adjusting body, the adjusting body is rotatably connected to the limiting base, so that the limiting hole can cooperate with the limiting block, and the fixing member can fix the adjusting body and the limiting base in a fixed connection.

[0023] By adopting the above technical solution, the limiting component is specifically set as a combination structure of a limiting base, an adjusting body, and a fixing component. This allows the limiting hole to be adjusted to a position that matches the limiting block by rotating the adjusting body, and then fixed by the fixing component after adjustment. This balances the adjustability and locking reliability of the limiting structure.

[0024] Preferably, the cross-section of the limiting block is a regular hexagon, and the limiting base is provided with two arc-shaped limiting surfaces that are arranged opposite to each other along the circumferential rotation of the adjusting body. The center of the two arc-shaped limiting surfaces is the rotation axis of the adjusting body. Each arc-shaped limiting surface is spirally arranged along the rotation axis of the adjusting body, and the spiral directions of the two arc-shaped limiting surfaces are opposite. The fixing component includes two fixing bolts, each of which corresponds to one of the arc-shaped limiting surfaces. Each fixing bolt is threaded onto the adjusting body and can abut against the arc-shaped limiting surface to fix the adjusting body in both directions around the circumference.

[0025] By adopting the above technical solution, by setting the limiting block as a regular hexagon, and cooperating with two arc-shaped limiting surfaces that are set oppositely and have opposite spiral directions, as well as two fixing bolts, a two-way locking can be formed in the circumference of the adjusting body, which is beneficial to improving the anti-loosening ability and limiting reliability of the adjusting body after it is fixed.

[0026] Preferably, the central angle α corresponding to the two ends of each of the arc-shaped limiting surfaces is ≥60°.

[0027] By adopting the above technical solution, and by limiting the central angle α corresponding to the two ends of each arc-shaped limiting surface to ≥60°, sufficient circumferential adjustment and limiting range can be provided for the adjusting body, thereby improving the adaptability of the limiting structure and the regular hexagonal limiting block.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a detachable threaded seat that slides on the flower basket body and forms a threaded engagement with the first pull rod, thereby separating the threaded connection structure from the load-bearing structure of the flower basket body. This avoids the severe wear caused by the flower basket body end being directly used as the threaded engagement part. After the threaded engagement part wears out, it can be repaired by replacing the threaded seat, thereby improving the service life of the flower basket body and reducing maintenance costs. 2. This application sets up a threaded seat structure that slides with the basket body and is restricted to prevent rotation, and sets up a locking structure with limiting parts, limiting blocks and limiting holes between the first pull rod and the basket body to achieve the length adjustment of the lashing device, while improving the stability of the first pull rod adjustment process and the locking reliability after the adjustment is in place, thereby improving the connection stability of the lashing device under ship vibration and swaying conditions. 3. This application, by setting a second tie rod structure with adjustable length in the second connecting mechanism, and a hook structure rotatably connected to the connecting seat, can not only adapt to different binding length requirements and facilitate quick on-site adjustment, but also allow the hook to adjust the angle according to the posture of the external connection point, thereby improving the assembly convenience, working condition adaptability and overall reliability of the binding device.

[0042] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0043] This application discloses a marine container lashing device. Example 1

[0044] Reference Figure 1 A marine container lashing device includes a basket body 1, a first connecting mechanism 2 disposed at one end of the basket body 1, and a second connecting mechanism 3 disposed at the other end of the basket body 1. The basket body 1 serves as the main load-bearing part of the entire lashing device. The first connecting mechanism 2 and the second connecting mechanism 3 are respectively used to connect to the hull fixing point and the container lashing point, and the overall length of the lashing device can be adjusted and tensioned through cooperation with the basket body 1.

[0045] The flower basket body 1 includes a rod 11 and a first end 12 and a second end 13 connecting the two ends of the rod 11. In a preferred embodiment, there are two rods 11 arranged parallel to each other, with their ends fixedly connected to the first end 12 and the second end 13, respectively, thus forming a frame structure with a central accommodating space. This arrangement of two rods 11 provides a stable mounting and sliding support position for the threaded seat 4, and also improves the overall stress stability of the flower basket body 1.

[0046] Reference Figure 2 The first connecting mechanism 2 includes a first pull rod 21 and a fork head 22. The first pull rod 21 is a screw, and the fork head 22 is fixedly disposed at one end of the first pull rod 21. The fork head 22 can be used to connect with a fixed connection part on the hull, such as a connecting lug, a fixing ring, or other pluggable fixed part on the hull. The other end of the first pull rod 21 extends toward the interior of the basket body 1.

[0047] Specifically, the fork head 22 has a U-shaped structure, with a through-hole pin at its end for connection to a seat on the hull. The pin passes through both the fork head 22 and the seat, thus connecting the fork head 22 to the seat. To improve the connection strength between the fork head 22 and the first pull rod 21, the fork head 22 has a insertion hole for the first pull rod 21. When the first pull rod 21 is inserted into the insertion hole, the pin hole on the fork head 22 aligns with the pin hole on the first pull rod 21. The pin shaft 23 is then inserted into the two pin holes in sequence, and the fork head 22 and the first pull rod 21 are welded and fixed together to improve the strength of the fixed connection between the fork head 22 and the first pull rod 21.

[0048] To ensure stable guidance of the first pull rod 21 during adjustment, in this embodiment, a mounting through hole 24 is provided on the first end 12, and the first pull rod 21 passes through the mounting through hole 24. The mounting through hole 24 guides and supports the first pull rod 21, enabling it to move stably along a predetermined axis during rotational adjustment, and helps ensure a stable and reliable threaded fit between the first pull rod 21 and the threaded seat 4. Preferably, the mounting through hole 24 can be configured as a closed through hole, making it less prone to significant wobble after the first pull rod 21 passes through, thereby improving the smoothness of adjustment.

[0049] A threaded seat 4 is detachably installed on the flower basket body 1, and the threaded seat 4 is slidably connected to the flower basket body 1. Specifically, the threaded seat 4 has two protrusions 41 at both ends, forming a semi-open groove 42 between the two protrusions 41. Each groove 42 corresponds to a rod 11. When installing the threaded seat 4 on the flower basket body 1, the threaded seat 4 is placed at an angle between the two rods 11, and the groove 42 is aligned with the rod 11. Then, the threaded seat 4 is rotated so that the rod 11 passes through the groove 42. Through this structure, the threaded seat 4 can be installed between the two rods 11 and slide along the length of the rod 11. At the same time, the two rods 11 can also restrict the circumferential posture of the threaded seat 4, preventing the threaded seat 4 from rotating synchronously when the first pull rod 21 rotates.

[0050] The threaded seat 4 is provided with a threaded through hole 43 that mates with the first pull rod 21, and a threaded connection is formed between the first pull rod 21 and the threaded through hole 43. In this way, the operator can rotate the basket body 1 during use to move the first pull rod 21 axially relative to the threaded seat 4, thereby adjusting the position of the first connecting mechanism 2 relative to the basket body 1, and thus adjusting the length of the entire binding device.

[0051] To improve the anti-loosening ability between the first pull rod 21 and the basket body 1, limiting members 5 are sleeved on the two rod parts 11. In this embodiment, the limiting member 5 includes a limiting sleeve 51, and a limiting hole 52 is formed inside the limiting sleeve 51. A limiting block 53 is fixedly provided at the end of the first pull rod 21 away from the fork head 22. In this embodiment, the cross-section of the limiting block 53 is square. The limiting hole 52 is adapted to the limiting block 53. Specifically, the distance between the two parallel sides of the limiting hole 52 is equal to the distance between the opposite sidewalls of the limiting block 53, so that when the limiting block 53 is inserted into the limiting hole 52, the limiting sleeve 51 fits against the opposite sidewall of the limiting block 53, thereby restricting the rotation of the limiting block 53. With this setting, after the lashing device is tightened to the position, the first tie rod 21 can be circumferentially locked by the cooperation between the limiting block 53 and the limiting hole 52, preventing the first tie rod 21 from loosening on its own under the action of ship vibration, swaying and alternating loads, thereby improving the locking reliability of the lashing device.

[0052] The second connecting mechanism 3 is located at the other end of the flower basket body 1 and is connected to the flower basket body 1 via a second end 13. The second connecting mechanism 3 includes a second pull rod 31 and a hook 32. The second pull rod 31 is located at the second end 13 and is adjustablely connected to the flower basket body 1. The second pull rod 31 is connected to the container via the hook 32. With this configuration, the second connecting mechanism 3 can be length-adjusted with the flower basket body 1 and can also be reliably connected to the lashing points on the container via the hook 32.

[0053] Reference Figure 1 , Figure 3and Figure 4 The second end 13 has a semi-open mounting hole 33, into which the second pull rod 31 can be placed. Multiple connecting blocks 34 are spaced apart along the length of the second pull rod 31. The circumferential dimension of each connecting block 34 is larger than that of the mounting hole 33, allowing the second end 13 to form a snap-fit ​​structure with the connecting blocks 34. Two blocking portions 35 are provided on the inner side of the second end 13, forming a blocking groove 36 between the two blocking portions 35 and the second end 13 for the connecting blocks 34 to be inserted. The connecting blocks 34 can be selectively inserted into the blocking groove 36 to adjust the extension length of the second pull rod 31 relative to the basket body 1. Simultaneously, the blocking groove 36 prevents the connecting blocks 34 from detaching from the basket body 1 when the second pull rod 31 is tightened, improving the stability of the connection between the second pull rod 31 and the second end 13.

[0054] The second connecting mechanism 3 adopts a stepped adjustment structure on one side. The operator can pre-select different positions of the connecting block 34 and the blocking groove 36 according to the actual binding distance required, thereby quickly adjusting the extension length of the second pull rod 31 and achieving coarse adjustment of the total length of the binding device. This reduces the rotational stroke required by relying solely on the threaded adjustment of the first pull rod 21, improving on-site installation efficiency.

[0055] Reference Figure 1 , Figure 5 The second pull rod 31 has a connecting seat 37 fixedly attached to its end. The connecting seat 37 has a connecting hole 38. One end of the hook-and-loop fastener 32 has a hook-like structure, and the other end passes through the connecting hole 38. The hook-and-loop fastener 32 is rotatably connected to the connecting seat 37, allowing the angle of the hook-and-loop fastener 32 to be adjusted. A blocking part 39 is provided at the end of the hook-and-loop fastener 32 passing through the connecting hole 38 to prevent the hook-and-loop fastener 32 from detaching from the connecting seat 37. With this configuration, when connecting the second pull rod 31 to the container, the hook-and-loop fastener 32 is first adjusted to an inclined state by rotating it in the connecting hole 38. Then, the hook-and-loop fastener 32 is passed through the hole structure on the container. Finally, the hook-and-loop fastener 32 is rotated to a position perpendicular to the second pull rod 31, so that the hook-and-loop fastener 32 is placed horizontally on the hole structure on the container, thus achieving the connection between the hook-and-loop fastener 32 and the container. The blocking part 39 is used to prevent the hook-and-loop fastener 32 from accidentally detaching from the connecting hole 38, ensuring reliable connection.

[0056] The implementation principle of Example 1 is as follows: In the process of fixing the container with the lashing device, the fork head 22 is first connected to the seat on the hull, and then the second tie rod 31 is connected to the container through the hook 32. Then, one end of the first tie rod 21 is inserted into the mounting through hole 24, and the corresponding connecting block 34 on the second tie rod 31 is inserted into the blocking groove 36 as needed. Then, the threaded seat 4 is placed between the two rods 11. Then, by rotating the basket body 1, the first tie rod 21 is inserted into the threaded through hole 43. By continuously rotating the basket body 1, the lashing device is gradually made to reach the required tension state. Then, the limiting sleeve 51 is slid so that the limiting sleeve 51 is fitted on the limiting block 53, thereby preventing the first tie rod 21 from loosening due to vibration or impact during long-term use.

[0057] During disassembly or maintenance, if the threaded parts wear due to long-term use, the first pull rod 21 can be removed, and the threaded seat 4 can be removed from the basket body 1. After replacing the threaded seat 4, the parts can be reassembled. Since there is no need to replace the main structure of the basket body 1, this helps to reduce maintenance costs and extend the overall service life of the device. Example 2

[0058] Reference Figure 6 , Figure 7 The difference between this embodiment and Embodiment 1 is that the limiting member 5 in this embodiment includes a limiting base 54, an adjusting body 55, and a fixing member 56. The limiting base 54 includes an annular portion 541 and ear plate portions 542 located on both sides of the annular portion 541. Each ear plate portion 542 has a through hole for the rod portion 11 to pass through. The rod portion 11 passes through the through hole, realizing a sliding connection between the limiting base 54 and the rod portion 11. A circular through hole is formed in the middle of the annular portion 541. The diameter of the circular through hole is larger than the diameter of the circumcircle of the limiting block 53, so that the limiting block 53 can pass smoothly through the circular through hole. The cross-section of the limiting block 53 in this embodiment is a regular hexagon.

[0059] Reference Figure 7 , Figure 8 An adjusting body 55 is disposed on one side of the annular portion 541. The adjusting body 55 protrudes outward to form two rotating support portions 551. Part of the annular portion 541 is slidably embedded in the rotating support portions 551, realizing a rotatable connection of the adjusting body 55 on the annular portion 541 with a rotation angle greater than 60°. A limiting hole 52 is disposed on the adjusting body 55 and is concentrically disposed with the circular through hole on the annular portion 541. The limiting hole 52 is a regular hexagonal structure adapted to the limiting block 53.

[0060] Reference Figure 8 , Figure 9 and Figure 10Two arc-shaped grooves 543 are provided on the side of the annular portion 541 facing the adjusting body 55, which are arranged opposite each other along the circumference of the annular portion 541. The bottom wall of the two arc-shaped grooves 543 is an arc-shaped limiting surface 544. The center of the two arc-shaped limiting surfaces 544 is the rotation axis of the adjusting body 55, and the central angle α corresponding to the two ends of the two arc-shaped limiting surfaces 544 is ≥60°. In this embodiment, α=60° is preferred. The distance between each arc-shaped limiting surface 544 and the opening of the arc-shaped groove 543 gradually changes from one end of the arc-shaped groove 543 to the other end, so that the arc-shaped limiting surface 544 is spirally arranged along the axial direction of the annular portion 541, and the spiral arrangement directions of the two arc-shaped limiting surfaces 544 are opposite.

[0061] Reference Figure 11 , Figure 12 In this embodiment, the fixing member 56 includes two fixing bolts 561, each with a hemispherical end. Each arc-shaped limiting surface 544 corresponds to one fixing bolt 561. The fixing bolts 561 are threaded onto the adjusting body 55, and their ends are inserted into the arc-shaped groove 543 and abut against the arc-shaped limiting surface 544. When the two fixing bolts 561 are pressed against their respective arc-shaped limiting surfaces 544, since the spiral directions of the two arc-shaped limiting surfaces 544 are opposite, the two fixing bolts 561 can constrain the adjusting body 55 from opposite force trends, thereby achieving bidirectional circumferential fixing of the adjusting body 55 and improving the stability and anti-loosening ability of the adjusting body 55 after locking.

[0062] The implementation principle of Example 2 is as follows: When the first pull rod 21 is loosened, the adjusting body 55 is rotated according to the final position of the limiting block 53 so that the limiting hole 52 matches the shape of the limiting block 53. Then, the two fixing bolts 561 are screwed on so that the fixing bolts 561 simultaneously press against the arc-shaped limiting surface 544, thereby achieving a fixed connection between the adjusting body 55 and the limiting base 54. Then, the first pull rod 21 is prevented from loosening by relying on the sliding connection between the limiting base 54 and the rod 11.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
