Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of marine structures, specifically a shock-absorbing component for marine lashing components. Background Technology
[0002] A ship is any means of transportation that uses the buoyancy of water and relies on human power, sails, engines (such as steam engines, gas turbines, diesel engines, and nuclear power units) to move on water by pulling, pushing, rowing, or driving propellers or high-pressure nozzles. Existing ships use containers, which are generally lashed together.
[0003] Typically, lashing is directly connected to the hull. After lashing, when the hull or cargo itself experiences severe vibration, it has a large external pulling force, which poses a risk of loosening or even breakage over the long term, resulting in poor reliability. Utility Model Content

[0022] Please see Figure 1-4 A shock absorber for marine lashing devices includes a damper 1, a connecting seat 2, a connecting piece 3, a connecting ring 4, a fixing bolt 5, a lock nut 6, a connecting seat 7, a connecting piece 8, a return spring 9, a connecting frame 10, and a perforated seat 11. The top of the damper 1 is connected to the middle of the bottom of the connecting seat 2. The middle of the top of the connecting seat 2 is connected to the bottom of the connecting ring 4. The upper left and right sides of the connecting seat 2 are respectively connected to the lower inner sides of a set of connecting pieces 3. The bottom of the damper 1 is connected to the middle of the top of the connecting seat 7. The lower bottom of the connecting seat 2 and the outer side of the top of the connecting seat 7 are connected to the return spring 9. The lower left and right sides of the connecting seat 7 are respectively connected to the upper inner sides of a set of connecting pieces 8. The front and rear sides of the connecting seat 7 are connected via a connecting... The frame 10 is connected to the front and rear sides of the top of the perforated seat 11. The fixing bolt 5 can pass through the connecting piece 1 3 or the connecting seat 2 7 and is screwed on the outside by the anti-loosening nut 6. The perforated seat 11 is also provided with a fixing structure. According to the actual shock absorption requirements, the corresponding number of this structure can be selected. The two adjacent sets of connecting pieces 1 3 and the two sets of connecting seats 2 7 are connected at the same time. The fixing bolt 5 passes through these two sets of connecting pieces 1 3 and is fixed on the protruding side by the anti-loosening nut 6. Multiple sets of this structure can be formed to jointly absorb shock. After one set of connecting ring 4 is connected to the external binding rope, the other side is connected to the perforated seat 11 through the fixing structure and fixed to the hull. When a violent vibration occurs, the energy can be dissipated by multiple sets of dampers 1 and the shock can be absorbed by the return spring 9.
[0023] The fixing structure includes a connecting rope 12, a fixing seat 13, and a through groove 14. One side of the connecting rope 12 can be movably passed through the perforated seat 11, and the other side of the connecting rope 12 is connected to the middle of the bottom side of the fixing seat 13. The fixing seat 13 is provided with multiple sets of through grooves 14 around its circumference. The connecting rope 12 can be passed through the perforated seat 11 and knotted to form an anti-detachment connection. The fixing seat 13 is placed on the corresponding surface of the ship and fixed inward by bolts passing through the through grooves 14, thus forming a fixed connection between the fixing seat 13 and the ship surface. The connecting rope 12 also prevents direct connection deformation and breakage, improving reliability.
[0024] It also includes anti-loosening washers 15. Anti-loosening washers 15 are provided on the inner side of the screw-in part of the fixing bolt 5 and anti-loosening nut 6. The anti-loosening washers 15 can push the fixing bolt 5 and anti-loosening nut 6 outward after screwing in, increase static friction to avoid slippage and improve stability.
[0025] It also includes a rounded corner 16, which is provided on the edge side of the connecting ring 4; the rounded corner 16 can blunt the edge corner of the connecting ring 4, reduce the risk of damage and breakage, and improve reliability.
[0026] It also includes an information board 17, with the outer side of a set of connecting brackets 10 connected to the inner side of the information board 17; the information board 17 can display the information of this structure, making it easier to read, distinguish and use, and improving convenience.
[0027] In summary, when using a shock absorber for marine lashing devices, depending on the actual damping requirements, a corresponding number of these structures can be selected. Two adjacent sets of connecting plates 3 and two sets of connecting seats 7 are simultaneously connected. The fixing bolts 5 pass through these two sets of connecting plates 3, and are secured with anti-loosening nuts 6 on the protruding side. Anti-loosening washers 15 provide outward support to the fixing bolts 5 and anti-loosening nuts 6 after screwing them in, increasing static friction and preventing slippage. This allows multiple sets of these structures to work together to dampen shocks. After one set of connecting rings 4 is connected to the external lashing rope, the other side connects to the connecting rope 12. By passing through the perforated seat 11, a knot can be tied to form an anti-detachment connection. The fixing seat 13 is placed on the corresponding surface of the ship, and the bolt is fixed inward by passing through the through groove 14, thus forming a fixed connection between the fixing seat 13 and the ship surface. The connecting rope 12 prevents direct deformation and breakage, and is fixed to the hull. In the event of severe vibration, the energy can be dissipated by multiple sets of dampers 1, and the shock can be damped by the reset spring 9. In addition, the rounded corner 16 can blunt the edge corner of the connecting ring 4, reducing the risk of damage and breakage. The information board 17 can display the structural information, which is convenient for reading, distinguishing and using, and improving convenience.
[0028] This damper 1 is a commercially available device known to those skilled in the art. We are simply using it here without making any structural or functional improvements, and we will not go into detail about it here.
