Description

A seismic-resistant connection and fastening structure for marine lashing bridges

Technical Field

This invention relates to the technical field of marine lashing bridges, specifically to a seismic-resistant connection and fastening structure for marine lashing bridges.

Background Technology

In maritime shipping, most containers are stacked on the deck and on the cargo hold covers. These containers will move laterally and longitudinally as the ship rolls and pitches. Laplock bridges effectively prevent cargo from falling into the water and being lost, and reduce the damage and danger to the ship and its crew caused by containers throughout the voyage. When lashing bridges are installed on container ships, they are connected to the fixed components on the container ship through the bottom of the lashing bridge.

Existing marine lashing bridges still have many inconveniences in use. When shipping containers are stacked, the containers on top may experience problems such as broken connectors, large gaps, or lack of connection.

To address the aforementioned shortcomings, a lightweight container ship lashing bridge disclosed in the prior art (application number CN202321286577.4, publication number 2023-12-01, Chinese Patent) can be referenced. This lashing bridge uses a clamping mechanism with grooves formed between every two square side bars to hold the container in place, allowing the gap between the square side bars to be larger. When the container is lowered by a crane, the larger gap reduces the difficulty of lowering it and also reduces friction between the container and the square side bars, improving the efficiency of container placement. This eliminates the need for fine-tuning the container's position during the lowering process, thus improving work efficiency.

Alternatively, reference can be made to the prior art (application number CN201380077728.8, publication date 2018-06-19) for a lashing bridge for cargo ships, in which each lashing bar is fixed at one end to a corner of a container and at the other end to a turnbuckle, the turnbuckle being sequentially fixed at its other end to the lashing bridge. This fixing is tightened by rotating the turnbuckle;

And refer to the prior art (application number CN201480077344.0, publication date Chinese patent 2019-11-05) for a lashing bridge for cargo ships, the vibration damper provided in the lashing bridge, depending on the characteristics of the mass element, the flexible element and the damping element, the operation of the vibration damper is linear or nonlinear, which can reduce the vibration tendency of the lashing bridge, and at the same time, make the lashing bridge lighter than before.

Although the aforementioned existing technologies can overcome the current shortcomings, there are still other shortcomings in the operation process. During the operation of the container, the limiting parts of the container are prone to loosening due to the movement of the ship and the force of the waves. It is necessary for the staff to check the limiting parts in time. Therefore, there are still shortcomings in the use.

Therefore, we propose a seismic-resistant connection and fastening structure for marine lashing bridges to address the problems mentioned above.

Detailed Implementation

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

Please refer to Figures 1-9. The present invention provides the following technical solutions:

Example 1: To address the issue that current marine lashing bridges on the market, during container transport at sea, are prone to loosening of their locking mechanisms due to ship movement and wave forces, requiring timely inspection by personnel, the following solution is provided (see Figures 1-7). This solution includes a docking base 5 fixed to the bottom of the ship, secured to the ship at its bottom by several sets of locking bolts 6. Several sets of uprights 1 and several sets of fixing seats 2 are fixed to the top of the docking base 5, connected to the uprights 1 and fixing seats 2 by welding connecting rods 3. Several sets of horizontal plates 4 are welded between the two sets of uprights 1. The solution also includes a sealing box 8 fixed to the bottom of the horizontal plates 4, with a servo motor 9 fixedly installed on the outer bottom of the sealing box 8. The output end of the servo motor 9 is connected to the bottom end of a threaded rod 10, and the outer side of the threaded rod 10 is threadedly connected to the outer side of a push plate 11. The upper and lower ends of the push plate 11 are fixed with seals 12. An oil cavity 13 is formed at the upper end of the push plate 11. The inner side of the seal 12 is attached to the outer side of the threaded rod 10. Several sets of first oil supply pipes 14 and several sets of second oil supply pipes 15 are connected to the upper end of the seal 12. A valve 16 is connected to the outer side of the middle of the first oil supply pipes 14 and the second oil supply pipes 15. A drive mechanism 17 is connected to the end of the first oil supply pipe 14 away from the sealing box 8. The outer side of the drive mechanism 17 is set on the fastening mechanism side. The drive mechanism 17 drives the fastening mechanism to prevent the container's limiting parts from falling off. The end of the second oil supply pipe 15 away from the sealing box 8 is connected to the side of the fixing plate 24. The fixing plate 24 is fixed to the inner side of the upright 1 and the fixing seat 2. Several mating parts 7 are set on the surface of the upright 1 and the fixing seat 2. The limiting parts achieve the mating and limiting treatment of the container through the setting of the mating parts 7. The drive mechanism 17 includes a piston block 1701 slidably disposed inside the first oil supply pipe 14. A connecting rod 1702 is fixed to the left side of the piston block 1701. The outer side of the connecting rod 1702 is fixed to the head end of a return spring 1703. The tail end of the return spring 1703 is fixed inside the first oil supply pipe 14. The outer side of the connecting rod 1702 is disposed inside a worm gear 1704. A set of spiral grooves 1705 are formed inside the worm gear 1704. The rear end of the worm gear 1704 is rotatably disposed inside a fixing block 23. The fixing block 23 is fixed to the surface of the upright 1 and the fixing seat 2 by bolts. The outer side of the piston block 1701 is attached to the inner side of the first oil supply pipe 14. The piston block 1701 and the connecting rod 1702 are integrally formed, and the connecting rod 1702 forms an elastic sliding structure with the interior of the first oil supply pipe 14 through the return spring 1703. The connecting rod 1702 consists of a sliding rod and a helical rod. The outer side of the helical rod is helically connected to the helical groove 1705 inside the worm 1704. The helical groove 1705 and the worm 1704 form a rotating structure through the helical rod and the interior of the fixing block 23. The fastening mechanism includes a worm wheel 18 meshing with the bottom of the worm 1704. The center of the worm wheel 18 is fixed to the outer side of the middle of the threaded sleeve 19. The outer sides of the left and right ends of the threaded sleeve 19 are rotatably set inside the support block 20. The bottom of the support block 20 is fixed inside the fixing block 23. The outer sides of the left and right ends of the threaded sleeve 19 are threadedly connected to the outer side of the screw 21. The outer end of the screw 21 is fixed to one side of the fastening block 22. The outer side of the fastening block 22 extends out of the outside of the fixing block 23. The end of the fastening block 22 extending out of the fixing block 23 is arc-shaped, and the thread directions of the two sets of screws 21 are opposite. The inner sides of the two sets of fastening blocks 22 are attached to the outer side of the container limiting component, and the threaded sleeve 19 forms a rotating structure between the worm gear 18 and the interior of the support block 20.

When in use, firstly, the limiting component is tied to the outside of the container, and the other end of the limiting component is positioned inside the two sets of fastening blocks 22, with the opposite faces of the fastening blocks 22 being arc-shaped. When fastening is required, first close the valve 16 on the outer side of the middle of the second oil supply pipe 15. At this time, by starting the servo motor 9, the output end of the servo motor 9 drives the fixedly connected threaded rod 10 to rotate. At this time, the pusher plate 11 threaded to the outer side of the threaded rod 10 will slide in the oil cavity 13 opened inside the sealed box 8. Since a seal 12 is provided at the connection between the pusher plate 11 and the threaded rod 10, the hydraulic oil at the top of the pusher plate 11 is prevented from leaking. At this time, the hydraulic oil will be transported through the first oil supply pipe 14. Since a drive mechanism 17 is provided inside the first oil supply pipe 14, the piston block 1701 attached inside the first oil supply pipe 14 will move by the compression of the hydraulic oil. The connecting rod 1702 fixed on one side of 1701 moves, and the movement of the connecting rod 1702 can drive the sliding rod and the screw rod to move. Since the screw rod is set inside the worm 1704, and the spiral groove 1705 opened inside the worm 1704 is spirally connected to the screw rod, and the screw rod has a large pitch, it is convenient for the movement of the screw rod to drive the spiral groove 1705 and the worm 1704 to rotate. Thus, the worm 1704 can rotate stably inside the fixed block 23. When the worm 1704 rotates, it can drive the meshing worm wheel 18 to drive the threaded sleeve 19 to rotate inside the fixed block 23, causing the screw 21 threaded inside the threaded sleeve 19 to move. The screw 21 is also fixed on one side of the fastening block 22, which can realize the relative movement of the two sets of oppositely set fastening blocks 22 to achieve the fastening treatment of the limiting part. Through the threaded connection and the self-locking property of the worm 1704 and the worm wheel 18, the purpose of preventing detachment can be achieved.

Example 2: Due to the high humidity of the ocean air during ship transportation, the surface of the ties is prone to rusting. Workers need to vibrate and loosen the rusted areas, as shown in Figures 1, 2, 8, and 9. Fixing frames 25 are fixed to both the upper and lower ends of the fixing plate 24. An extension block 26 is slidably installed inside the fixing frame 25. The extension block 26 extends into one side of the upright 1 and is connected by several sets of connecting springs 27. The outer end of the extension block 26 is rotatably positioned at the bottom of the striking element 28. The middle part of the striking element 28 is rotatably positioned inside the connecting shaft 29. The back of the connecting shaft 29 is fixed to the inner side of the upright 1 and the fixing seat 2. The striking element 28 is Z-shaped, and the middle part of the threaded rod 10 is rotatably connected to the connecting shaft 29. There is a gap between the top of the striking element 28 and the upright 1 and the fixing seat 2. The outer side of the extension block 26 is sealed and fitted to the inner side of the fixing frame 25, and there is a hole between the fixing frame 25 and the fixing plate 24 to facilitate the flow of hydraulic oil.

When needed, by closing valve 16 on one side of the first oil supply pipe 14 and opening valve 16 on one side of the second oil supply pipe 15, the rotation of the threaded rod 10 can be achieved by the forward and reverse rotation of the servo motor 9, which can drive the threaded push plate 11 to move. At this time, hydraulic oil can be delivered to the interior of the fixed plate 24 through the second oil supply pipe 15. The hydraulic oil inside the fixed plate 24 will be delivered to the interior of the fixed frame 25 through the hole, which can extend the position of the extension block 26 slidably set inside the fixed frame 25. This allows the extension block 26 to drive the connecting spring 27 to deform, and the position of the striking part 28 will also change. The middle position of the striking part 28 will rotate through the connecting shaft 29, and the end position of the striking part 28 away from the extension block 26 will also strike the inner side of the upright 1 and the fixed seat 2. At this time, the rust on the surface of the upright 1 and the fixed seat 2 can be vibrated off, which is convenient for subsequent painting.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
