Description

Technical Field

[0001] This utility model relates to the field of ship tie rod technology, specifically a container tie rod structure for ship transportation. Background Technology

[0002] Ship lashing rods, also known as container lashing rods, are key load-bearing components on container ships used to secure containers on the deck and inside the hold. Their core function is to resist the lateral, longitudinal, and vertical forces generated by wind, waves, rolling, and vibration during ship navigation, preventing containers from shifting, tilting, or falling.

[0003] Existing ship tie rods are generally assembled manually on containers. During assembly, two tie rods are needed to form an X-shape to fix one side of the container. The two intersecting tie rods cannot be on the same plane and must be located on one side of the container. When installing tie rods located at high positions, it is inconvenient to observe from the high position, so the position needs to be repeatedly calibrated. Moreover, the slender rods and their own weight make the installation time-consuming and labor-intensive.

[0004] Therefore, the existing technical solutions have the following drawbacks:

[0005] 1. The calibration of the installation position of the tie rod at a high location is difficult, time-consuming and labor-intensive;

[0006] 2. It is inconvenient to observe the ear from a high position, and misalignment is easy to occur.

[0007] Therefore, we propose a container tie rod structure for ship transportation. Utility Model Content

[0008] This utility model provides a container tie rod structure for ship transportation, which has the beneficial effects of automatic centering and separate installation positions, eliminating laborious calibration and simplifying the installation difficulty of the tie rod, thus solving the problems mentioned in the background art.

[0009] This utility model provides the following technical solution: a container tie rod structure for ship transportation, including an ear and a rod. A movable head is provided on one side of the ear, and a hanging ring is provided at the end of the rod. The rod is fitted onto the movable head through the hanging ring. A partition step is provided on the movable head, and the end face of the partition step has an arc-shaped structure. The partition step divides the top of the movable head into two concave suspension grooves for placing the hanging ring. A fixing rivet is pinned to the movable head, and the fixing rivet is fixed to the movable head by bolts to prevent the hanging ring from falling off. The interior of the movable head is also provided with a co-assembly structure to prevent the hanging ring from being installed off-center.

[0010] Specifically, the ear is provided with a fixing head for connecting the container on the side away from the movable head. The ear is installed on the movable head container through the fixing head and the movable head extends out of the container, thereby locking the stacked containers.

[0011] More specifically, the ring body has a circular cross-sectional structure, and the end face of the concave suspension groove separated by the aforementioned partition steps on the movable head has an arc-shaped structure. The ring slides to the center of the arc-shaped end face of the concave suspension groove, thereby automatically centering the ring and making it fit firmly against the concave suspension groove.

[0012] Specifically, a flower basket is connected to the bottom of the pole, and another pole is connected to the flower basket. The two poles are locked to the two centrally symmetrical ears of the container through the flower basket.

[0013] More specifically, threaded assembly portions are provided at both ends of the rod, and the hanging ring is threadedly engaged with the threaded assembly portions.

[0014] More specifically, the rod is connected to an extension section via the threaded assembly, which can lengthen the rod.

[0015] Specifically, the assembly structure includes a cavity disposed inside the movable head, a movable block is slidably installed in the cavity, the top horizontal plane of the movable block coincides with the top horizontal plane of the partition step, and the movable block slides along the cavity on any side of the partition step.

[0016] More specifically, the front end of the movable head is provided with a limiting groove, and the movable block is provided with a pull handle that passes through the limiting groove. The pull handle moves left and right along the limiting groove on the movable head.

[0017] Specifically, the bottom of the movable head is provided with a reinforcing rib, and the sum of the height of the movable head and the height of the reinforcing rib is less than the inner diameter of the hanging ring.

[0018] More specifically, the end face structure of the reinforcing rib is tooth-like, and several reinforcing ribs are provided along the bottom of the movable head.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this type of container tie rod structure for ship transportation, the partition step and the outer wall of the movable head cooperate to form an arc-shaped end face of the concave suspension groove, thereby enabling the hanging ring to automatically center.

[0021] 2. In this type of container tie rod structure for ship transportation, the movable head is divided into two concave suspension grooves by a partition step, so that the hanging ring at the top of the rod can be fitted, allowing the rod to be installed at different positions of the ear, so that the tie rod can cross without overlapping during assembly.

[0022] 3. In this type of container tie rod structure for ship transportation, the load-bearing capacity of the movable head is improved by reinforcing ribs to prevent deformation of the ear after being subjected to force, thereby improving the service life of the ear.

[0023] 4. In this type of container tie rod structure for ship transportation, threaded assembly parts are opened at both ends of the rod to allow for the combination of extension sections for extension, and the hanging ring is also set as a detachable structure with threaded assembly, so that the hanging ring can be replaced.

[0024] 5. In this type of container tie rod structure for ship transportation, the two concave suspension grooves on the ear can be closed by the set movable block, so as to avoid the problem of the position of the hanging ring being difficult to calibrate and the adjustment being laborious when the hanging ring is installed at the height.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] like Figures 1 to 8 As shown, the present invention provides a container tie rod structure for ship transportation, including an ear part 1 and a rod part 2. A basket is connected to the bottom of the rod part 2, and the basket is connected to another rod part 2. The two rod parts 2 lock the two centrally symmetrically arranged ears 1 of the container through the basket. The spacing between the two rod parts 2 is adjusted by the basket to lock the two ears 1 located diagonally opposite each other in the container, thereby fixing the container. A movable head 10 is provided on one side of the ear part 1, and a hanging ring 20 is provided at the end of the rod part 2. The rod part 2 is fitted onto the movable head 10 through the hanging ring 20. A fixed head 14 for connecting the container is provided on the side of the ear part 1 away from the movable head 10. The ear part 1 is installed on the movable head 10 of the container through the fixed head 14 and the movable head 10 extends out of the container. The two ends of the ear part 1 are respectively used to connect the hanging ring 20 of the rod part 2 and to fix itself to the container.

[0036] refer to Figure 3 The movable head 10 is provided with a dividing step 11. The end face of the dividing step 11 is arc-shaped. The dividing step 11 divides the top of the movable head 10 into two concave suspension grooves 12 for placing the hanging ring 20. A fixing rivet 13 is pinned to the movable head 10 and fixed to the movable head 10 by bolts to prevent the hanging ring 20 from falling out. The ring body of the hanging ring 20 has a circular cross-sectional structure. The end face structure of the concave suspension groove 12 on the movable head 10 divided by the dividing step 11 is arc-shaped. The hanging ring 20 slides to the center of the arc-shaped end face of the concave suspension groove 12. The rod 2 is fitted onto the movable head 10 via a hanging ring 20. Since the top of the movable head 10 is divided into two concave suspension grooves 12 by the partition step 11, the installation position of the rod 2 can be adjusted so that the two rods 2 can be fixed in a cross but not overlapping manner on one side of the container. Moreover, when the hanging ring 20 is fitted onto the top of the rod 2, the hanging ring 20 will slide along the outer wall of the movable head 10 and the partition step 11 to the center of the concave suspension groove 12, thereby automatically centering it and firmly fitting it with the movable head 10, ensuring that it is stable and secure when fixed.

[0037] refer to Figures 6-8The movable head 10 also has an internal assembly structure to prevent the hanging ring 20 from being misaligned. The assembly structure includes a cavity 30 inside the movable head 10, in which a movable block 3 is slidably installed. The top horizontal plane of the movable block 3 coincides with the top horizontal plane of the partition step 11. The movable block 3 slides along the cavity 30 on either side of the partition step 11. The front end of the movable head 10 has a limiting groove 31, and the movable block 3 has a pull handle 32 that passes through the limiting groove 31. The pull handle 32 moves left and right along the limiting groove 31 on the movable head 10. The movable block 3 closes the concave suspension groove 12 by sliding to prevent the hanging ring 20 on the rod 2 from being misaligned. By closing the concave suspension groove 12, the rod 2 can be accurately fitted into the concave suspension groove 12 in the appropriate position through the hanging ring 20, thus eliminating the need to repeatedly calibrate the fitting position of the hanging ring 20 and solving the problem of difficult calibration when installing the hanging ring 20 at a high position.

[0038] refer to Figure 2 , Figure 4 and Figure 5 Both ends of the rod 2 are provided with threaded assembly parts 21. The hanging ring 20 is threadedly engaged with the threaded assembly parts 21. The rod 2 is connected to the extension section 4 through the threaded assembly parts 21. The rod 2 is connected to the hanging ring 20 and the extension section 4 through the threaded assembly parts 21, which makes it convenient for users to replace the hanging ring 20 and adjust the length of the rod 2 so that it can be used to fix containers of different stacking heights.

[0039] refer to Figure 3 The bottom of the movable head 10 is provided with a reinforcing rib 15. The end face structure of the reinforcing rib 15 is tooth-like. Several reinforcing ribs 15 are provided along the bottom of the movable head 10. The sum of the height of the movable head 10 and the height of the reinforcing rib 15 is less than the inner diameter of the hanging ring 20. The reinforcing rib 15 can improve the load-bearing capacity of the movable head 10 and effectively prevent the ear 1 from deforming after being subjected to force, thereby improving its service life.

[0040] When securing containers stacked on a ship, after installing the lug 1 onto the container, the rod 2 is assembled via the threaded assembly part 21. After threading the hanging ring 20 onto one end of the rod 2, an extension section 4 is optionally installed according to the length requirements, so that the two rods 2 connected by the basket can contact the lug 1 at the corresponding positions. Then, according to the installation requirements, the rod 2 is installed in the recessed suspension groove 12 at the appropriate position of the front and rear rods via the hanging ring 20, so that two non-overlapping tie rods can be installed on the same side of the container, thus firmly securing the stacked containers.

[0041] Furthermore, in this embodiment, the assembly process of the mounting rod 2 has been further optimized. By pre-adjusting the movable block 3, the movable block 3 is pushed in the cavity 30 by the pull handle 32 so that it can close one of the concave suspension grooves 12. When the rod 2 is fitted with the hanging ring 20, only one concave suspension groove 12 is left on the ear 1 to avoid the hanging ring 20 being installed in the wrong position. This avoids the rod 2 from easily crossing on the same plane during assembly, which would cause the need to recalibrate the position.

[0042] In summary, in this type of container tie rod structure for ship transportation, the movable head 10 of the ear 1 is divided into two concave suspension grooves 12 by the partition step 11, so that the hanging ring 20 at the top of the rod 2 can be fitted. This allows the rod 2 to be installed at different positions on the ear 1, so that the tie rod can cross without overlapping during assembly. Moreover, the movable block 3 can close the two concave suspension grooves 12 on the ear 1, avoiding the problem of difficulty in calibrating the position of the hanging ring 20 and the difficulty in adjusting it when it is fitted at the height.
