Description

Technical Field

[0001] The invention belongs to the field of lashing devices, and in particular relates to a fastening lashing device for a large-scale ship container. Background Art

[0002] With the booming development of global trade, maritime transport, as one of the most important modes of cargo transportation, undertakes a large number of cargo transportation tasks. In the process of sea transportation, large containers, as standardized cargo loading containers, are widely used in various types of ships. However, most of the existing container fastening and lashing devices can only be applied to containers of specific standard sizes, and cannot be applied to containers of different standard sizes, and have low applicability.

[0003] A Chinese patent with patent announcement number CN221499194U discloses a fastening device for ship containers. The device is provided with a plurality of rectangular grid-shaped positioning holes on a support seat. When containers of different specifications and sizes are placed on the support seat, limiting columns can be inserted into the limiting holes around the support seat to perform multi-point limiting. Supports and binding components are provided, and the spacing between the supports is adjustable. The connecting ropes are sequentially passed through the connecting rings on the limiting columns to limit the four sides of the container, thereby enhancing the fastening effect and being suitable for containers of different standard sizes. However, after the device fixes multiple containers, the device is subject to greater turbulence during the transportation of the ship, which inevitably causes friction and collision between adjacent containers, resulting in damage to the containers and even loosening of the fastening and binding device.

[0040] It should be noted that these attached drawings and text descriptions are not intended to limit the scope of the concept of the present invention in any way, but to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0041] Now, the present invention will be further described in detail with reference to the attached drawings.

[0042] Please refer to Figure 1-8As shown in the figure, in this embodiment, a fastening and lashing device for a large marine container is provided, including a base 1, on the top of which there is an installation frame 11. On the installation frame 11, a winding wheel 10 around which a lashing belt 5 is wound is rotatably connected through a first rotating shaft 16. An adjusting component 8 for limiting the winding wheel 10 is arranged on the installation frame 11. A buckle 6 is arranged on the lashing belt 5. A hook ring 3 is movably connected to the base 1. On the base 1, there are a first guard plate 12 and a second guard plate 13 arranged oppositely. A buffer component 7 is arranged between the first guard plate 12 and the second guard plate 13. The buffer component 7 includes a plurality of support rods 72, which are relatively fixedly connected to the first guard plate 12. A connecting rod 71 is rotatably connected to each of the plurality of support rods 72. The first ends of the plurality of connecting rods 71 are hinged to the second guard plate 13. A fixing rod 74 is fixedly connected to the second ends of the plurality of connecting rods 71. A plurality of first tension springs 73 are movably connected between the fixing rod 74 and the first guard plate 12.

[0043] Specifically, in this embodiment, mounting plates 4 are relatively fixedly connected to the base 1. Through the mounting plates 4, it is convenient to fix the base 1 on the ship. By installing the base 1 between adjacent containers, and making the two guard plates fit with the adjacent containers respectively, then the lashing belt 5 is pulled out along the winding wheel 10 through the buckle 6, and the lashing belt 5 is lashed on the container. After that, the buckle 6 is fixedly connected to the hook ring 3. The winding wheel 10 tightens the lashing belt 5, and then the adjusting component 8 limits the winding wheel 10 to ensure that the lashing belt 5 fixes the container. When the container shakes during the ship transportation process, the container drives the connecting rod 71 to rotate along the support rod 72 through the two guard plates, so that the connecting rod 71 pulls the first tension spring 73. Through the elastic deformation of the first tension spring 73, the impact force of the container is buffered, the shaking and damage risk of the container are reduced, the transportation safety is improved, and at the same time, the phenomenon that the containers collide with each other and cause damage is avoided, and the phenomenon that the fastening structure for lashing the containers is damaged is also avoided.

[0044] It should be noted that in order to improve the stability of the container during transportation, multiple groups of this device can be arranged oppositely along the container to achieve all-round lashing of the container, further improving the stability of the container during transportation. At the same time, the materials of the installation frame 11 and the winding wheel 10 should be selected as high-strength and corrosion-resistant materials to adapt to the humid and high-salt environment at sea.

[0045] In this embodiment, as Figure 1 、 Figure 2 and Figure 3As shown, shock absorbers 15 are oppositely provided on the first guard plate 12 and the second guard plate 13. The first end of the shock absorber 15 is fixedly connected to the first guard plate 12, and the second end of the shock absorber 15 is hinged to the second guard plate 13. Specifically, when relative displacement occurs between the first guard plate 12 and the second guard plate 13 due to the shaking or impact force of the container, the damping structure inside the shock absorber 15 will consume energy, slow down the displacement speed, play a role in shock absorption and buffering, further enhance the buffering effect, and work together with the buffer assembly 7 to better cope with the complex bumpy conditions during ship navigation, effectively reduce the possibility of the container being damaged due to vibration, and improve the reliability of the fastening and lashing device. It should be noted that the selection of the shock absorber 15 should be determined according to the type of the ship, the weight of the container, and the sea conditions of the expected voyage to ensure that it can provide appropriate damping force and stroke. When installing the shock absorber 15, it is necessary to ensure that its installation position is accurate and the connection is firm to give full play to its shock absorption function.

[0046] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, buffer pads 14 are fixedly connected to one end of the first guard plate 12 and the second guard plate 13 away from the shock absorber 15. The buffer pad 14 includes a protective layer 141, anti-slip particles 144, and an air cushion layer 142 and a sponge layer 143 arranged inside the protective layer 141. The air cushion layer 142 is fixedly connected inside the protective layer 141. The sponge layer 143 is in multiple groups and is arranged oppositely in a surrounding shape on the outer wall of the air cushion layer 142. The anti-slip particles 144 are fixedly connected to the side of the protective layer 141 in contact with the container. Specifically, the buffer pad 14 can directly protect the part of the container in contact with the guard plate, reduce wear and collision damage. The combined design of the air cushion layer 142 and the sponge layer 143 further optimizes the buffering performance. The synergistic effect of different materials and structures can better adapt to different degrees of impact force; the design of the anti-slip particles 144 enhances the fixing effect on the container. It should be noted that in this embodiment, the material of the buffer pad 14 should be selected to be wear-resistant, corrosion-resistant, and have good buffering performance. The protective layer 141 can be made of rubber material, the air cushion layer 142 can use a high-strength rubber airbag, and the sponge layer 143 can be selected from high-density sponge. The thickness, hardness and other parameters of the air cushion layer 142 and the sponge layer 143 should be optimized and adjusted according to the weight of the container and the actual use situation. The sealing performance of the protective layer 141 should be good to prevent seawater or other liquids from entering and affecting the performance of the air cushion layer 142 and the sponge layer 143.

[0047] In this embodiment, as Figure 1As shown, a lifting assembly 9 is provided between the guard plate 12 and the base 1, and the lifting assembly 9 includes a threaded sleeve 91 and two threaded rods 92 arranged at both ends of the threaded sleeve 91. The threaded sleeve 91 is sleeved and threadedly connected in the threaded sleeve 91, and the ends of the two threaded rods 92 away from the threaded sleeve 91 are respectively fixedly connected to the guard plate 12 and the base 1. Specifically, by rotating the threaded sleeve 91, since the threaded sleeve 91 is threadedly connected to the two threaded rods 92, and the two threaded rods 92 are respectively fixedly connected to the guard plate 12 and the base 1, according to the principle of thread transmission, the threaded sleeve 91 The rotation will cause the two threaded rods 92 to move relative to each other, thereby realizing the lifting and lowering of the guard plate 12 relative to the base 1. The height of the guard plate 12 can be flexibly adjusted according to the height of the container or different loading requirements, so that the fastening and binding device can better adapt to containers of various specifications, thereby improving the versatility of the device. It should be noted that the material of the threaded sleeve 91 and the threaded rod 92 should have sufficient strength and wear resistance to withstand the pressure and friction during the lifting process. During use, lubricating oil can be applied to the threaded part to reduce wear and improve the smoothness of the lifting operation.

[0048] In this embodiment, if Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the adjusting assembly 8 includes a third rotating shaft 85 which is rotatably arranged on the mounting frame 11. A ratchet wheel 86 is sleeved and fixedly connected to the third rotating shaft 85. A gear 83 which meshes with the ratchet wheel 86 is sleeved and fixedly connected to the first rotating shaft 16. A driving handle 81 is fixedly connected to the driving end of the third rotating shaft 85. A second rotating shaft 84 is rotatably connected to the mounting frame 11. A limiting mechanism 82 for limiting the ratchet wheel 86 is provided on the second rotating shaft 84. The limiting mechanism 82 includes a pawl 823 which is sleeved and fixedly connected to the second rotating shaft 84. The pawl 823 is configured to limit the ratchet wheel 86. A movable plate 821 is sleeved and movably connected to the second rotating shaft 84. A movable groove 824 which can be movably connected to the second rotating shaft 84 is provided through the movable plate 821. A clamping block 826 is fixedly connected to the first end of the movable plate 821. A clamping groove 18 which can be clamped with the clamping block 826 is embedded in the pawl 823. A fitting wheel 825 which abuts against the movable plate 821 is sleeved and fixedly connected to the third rotating shaft 85. A second tension spring 822 has its two ends respectively hinged to the mounting frame 11 and the second end of the movable plate 821. The pawl 823 has a handle end 19 for controlling its rotation and a clamping end 17 for limiting the ratchet wheel 86. Specifically, when tightening the binding band 5, by rotating the driving handle 81, the third rotating shaft 85 is driven to rotate. The ratchet wheel 86 on the third rotating shaft 85 rotates accordingly. Since the gear 83 meshes with the ratchet wheel 86 and the gear 83 is fixed on the first rotating shaft 16, the first rotating shaft 16 is driven to rotate, realizing the rotation of the winding wheel 10 to tighten the binding band 5. At this time, when the third rotating shaft 85 rotates (at this time, the rotation of the winding wheel 10 is for tightening the binding band 5), the ratchet wheel 86 rotates accordingly and abuts against the clamping end 17 of the pawl 823. Due to the special shape of the pawl 823, the ratchet wheel 86 pushes the pawl 823 to rotate around the second rotating shaft 84, thereby driving the tension spring to stretch through the movable plate 821. At this time, the pawl 823 loses the limiting effect on the ratchet wheel 86, and the ratchet wheel 86 can rotate freely to realize the tightening effect on the binding band 5. At the same time, since the movable plate 821 is clamped with the clamping groove 18 of the pawl 823 through the clamping block 826, the connection between the two is stable. At the same time, the fitting wheel 825 supports the movable plate 821 to achieve the balance between the ratchet wheel 86 and the pawl 823, so that the pawl 823 can always be in contact with the ratchet wheel 86. The advantage of this is that after the binding band 5 binds and secures the container, the slack of the binding band 5 can be prevented, improving the stability of the binding of the container;When it is necessary to pull out the binding strap 5, the winding wheel 10 is driven to reverse. Due to the special structures of the pawl 823 and the ratchet wheel 86, the pawl 823 limits the ratchet wheel 86 when pulling out the binding strap 5. Therefore, at this time, the handle end 19 of the pawl 823 can be held by hand, and the pawl 823 is driven by the handle to move away from the ratchet wheel 86 to release the limit on the ratchet wheel 86, that is, to release the limit on the gear 83 and the first rotating shaft 16. At this time, the binding strap 5 can be pulled out along the winding wheel 10. The overall structure is simple to operate and has high stability, ensuring that the binding strap 5 will not loosen after being tightened and improving the stability of the tightening effect; it should be noted that the movable plate 821 is installed inside the installation frame 11 and will not break away from the second rotating shaft 84. The setting of the movable groove 824 ensures that the movable plate 821 can move along the second rotating shaft 84 to facilitate the rotation of the pawl 823.;

[0049] In this embodiment, as Figure 1 shown, a chain 2 is movably connected between the base 1 and the hook ring 3.

[0050] Working principle:

[0051] First, the base 1 is fixed on the ship through the mounting plate 4. By installing the base 1 between adjacent containers, according to the height of the containers, by rotating the threaded sleeve 91, since the threaded sleeve 91 is threadedly connected to the two threaded rods 92, and the two threaded rods 92 are respectively fixed to the first guard plate 12 and the base 1, according to the principle of screw drive, the rotation of the threaded sleeve 91 will cause the two threaded rods 92 to move relatively, so as to realize the lifting of the first guard plate 12 relative to the base 1 to reach the specified height, and at the same time make the two guard plates fit with the adjacent containers respectively. Then, the binding strap 5 is pulled out along the winding wheel 10 through the buckle 6, and the binding strap 5 is tied to the container. After that, the buckle 6 is fixedly connected to the hook ring 3, and the winding wheel 10 tightens the binding strap 5. Then, the winding wheel 10 is limited by the adjusting component 8 to ensure that the binding strap 5 fixes the container. When the container shakes during the ship transportation process, the container drives the connecting rod 71 to rotate along the support rod 72 through the two guard plates, so that the connecting rod 71 pulls the first tension spring 73, and the elastic deformation of the first tension spring 73 is used to buffer the impact force of the container, reducing the risk of shaking and damage of the container. At the same time, the damping structure inside the shock absorber 15 will consume energy, slow down the displacement speed, and the buffer pad 14 can directly protect the contact part between the container and the guard plate, reducing wear and collision damage, improving the transportation safety, and at the same time avoiding the phenomenon of damage caused by collision between containers, and also avoiding the damage of the fastening structure for tying the containers.

[0052] The present invention is not limited to the above embodiments.
