Description

Technical Field

[0001] This invention relates to the field of container technology, specifically to a bulkhead support mechanism and its container. Background Technology

[0002] As the core carrier in the modern logistics and transportation system, containers are vertically stacked to make full use of the space resources of transportation vehicles and storage sites. This has become the mainstream method for container storage and transportation. By stacking multiple containers vertically, the container carrying capacity per unit space can be significantly increased, and transportation and storage costs can be reduced.

[0003] Currently, container stacking structures still suffer from stability defects in practical applications, especially during maritime transport. At present, when containers are stacked vertically, they are typically positioned by simple interlocking of their bottom corner brackets with the top corner brackets of the container below, sometimes supplemented by temporary securing straps or locks. However, this method of fixing has limited load-bearing capacity and resistance to displacement, failing to create a stable support structure.

[0004] Specifically, during maritime transport, the ship inevitably sways due to natural factors such as sea winds, waves, and ocean currents. This swaying motion is directly transmitted to the containers stacked on the deck or in the cargo hold. Containers located at higher elevations, due to their higher center of gravity, are more prone to swaying and even lateral displacement under inertia. This can lead to loosening and wear of the interlocking structures between containers, and in severe cases, even tilting or collapsing the entire stack of containers. Therefore, this invention proposes a bulkhead support mechanism and its container to effectively address these drawbacks. Summary of the Invention

[0005] The purpose of this invention is to provide a bulkhead support mechanism and its container to solve the problems mentioned in the background art.

[0006] This invention is achieved through the following technical solution: a bulkhead support mechanism, comprising: The support frame is a rectangular frame structure formed by two longitudinal support beams, a front crossbeam, and a rear crossbeam.

The support frame has surfaces A, B, and C. When the support frame is rotated to a horizontal position around the hinge and the front crossbeam is located in front of the top crossbeam of the end frame, surfaces A, B, and C respectively contact the two side walls and the top wall of the top crossbeam of the end frame.

[0007] Optionally, the hinge portion has two parts, each of which includes a bushing, a pin, and a hinge seat; The two hinged parts correspond to the two supporting longitudinal beams respectively.

[0010] Optionally, a walkway slab is fixedly laid on one side of the support frame, and the walkway slab covers the rectangular space enclosed by the two support longitudinal beams, the front crossbeam, and the rear crossbeam.

[0011] Optionally, the top crossbeam of the end frame is provided with a spring pin on the side facing the hinge, and the support frame has a pin hole for the spring pin to be inserted. When the support frame is rotated around the hinge to a horizontal position and the front crossbeam is located in front of the top crossbeam of the end frame, the spring pin is facing the pin hole.

Detailed Implementation

[0019] 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.

[0020] Example 1: Please refer to Figure 1 - Figure 4 This application proposes a bulkhead support mechanism, including a support frame 100, a hinge portion 200, and an end frame top crossbeam 300. The support frame 100 is a rectangular frame structure formed by two longitudinal support beams 101, a front crossbeam 102, and a rear crossbeam 103. A walkway 104 is fixedly laid on one side of the support frame 100, covering the rectangular space enclosed by the two longitudinal support beams 101, the front crossbeam 102, and the rear crossbeam 103. Specifically, the walkway 104 is mesh-like, and the walkway 104 is bolted or welded to the support frame 1.

[0021] The hinge portion 200 is located on one side of the rear crossbeam 103 of the support frame 100 and is connected to the support frame 100. The support frame 100 can rotate around the hinge portion 200. There are two hinge portions 200, each of which includes a bushing 201, a pin 202, and a hinge seat 203. The two hinge portions 200 correspond to two support longitudinal beams 101 respectively. The rear end of the support longitudinal beam 101 extends beyond the rear crossbeam 103. The bushing 201 is fixedly connected to the lower surface of the support longitudinal beam 101. The pin 202 is fixed on the hinge seat 203 and movably inserted into the bushing 201. Therefore, the support frame 100 can rotate around the bushing 201.

[0022] It should be added that the bushing 201 is welded and fixed to the support longitudinal beam 101, while the pin 202 is fixed to the hinge seat 203 by bolt connection.

[0023] The top crossbeam 300 of the end frame is parallel to the front crossbeam 102 and the rear crossbeam 103 and is located on the front side of the hinge part 200. The side of the top crossbeam 300 of the end frame facing the hinge part 200 is provided with a spring pin 301. The support frame 100 has a pin hole for the spring pin 301 to be inserted. When the support frame 100 is rotated around the hinge part 200 to a horizontal position and the front crossbeam 102 is located on the front side of the top crossbeam 300 of the end frame, the spring pin 301 is facing the pin hole. At this time, one end of the spring pin 301 can be automatically inserted into the pin hole, which can fix the support frame 100 to maintain a horizontal position.

[0024] Furthermore, the support frame 100 has surfaces A, B, and C. When the support frame 100 is rotated to a horizontal position around the hinge 200 and the front crossbeam 102 is located in front of the top crossbeam 300 of the end frame, surfaces A, B, and C contact the side walls and top wall of the top crossbeam 300 of the end frame, respectively. Specifically, a support leg 400 is provided at the rear end of the support longitudinal beam 101 near the bushing 201; surface A is the side of the support leg 400 facing away from the hinge 200, surface B is the lower surface of the support longitudinal beam 101, and surface C is the side of the rear crossbeam 103 facing the hinge 200.

[0025] It is worth mentioning that one of the legs 400 near the spring pin 301 has a pin hole for the spring pin 301 to be inserted, and the leg 400 is welded and fixed to the support beam 101.

[0026] In addition, a traction triangle plate 105 is welded to one end of the two supporting longitudinal beams 101 away from the hinge part 200. The traction triangle plate 105 has a rope hole, and a traction rope can be attached to the rope hole. Its function is to control the support frame 100 to flip backward.

[0027] Example 2: Please refer to Figure 6 and Figure 7 This application proposes a bulkhead support mechanism. The difference between this embodiment and Embodiment 1 is that there are two hinge portions 200, each including a movable ring 204 and a carabiner 205. Each hinge portion 200 corresponds to one of two supporting longitudinal beams 101, with the rear end of the supporting longitudinal beam 101 extending beyond the rear crossbeam 103. The movable ring 204 is fixedly connected to the rear end of the supporting longitudinal beam 101, and the carabiner 205 is fastened to the movable ring 204. Therefore, when the position of the carabiner 205 is fixed, the support frame 100 can also rotate around the carabiner 205.

[0028] On the other hand, a support leg 400 is welded to the lower rear surface of the supporting longitudinal beam 101, and the inner surface of the support leg 400 near the spring pin 301 forms a pin hole; and surface A is the side of the support leg 400 facing away from the hinge part 200, surface B is the lower surface of the supporting longitudinal beam 101, and surface C is the side of the rear crossbeam 103 facing the hinge part 200. Since surfaces A, B, and C on the support frame 100 are all in contact with the top crossbeam 300 of the end frame, the support frame 100 can maintain stability and a certain rigidity when it is in a horizontal position.

[0029] Example 3: Please refer to Figure 10 - Figure 13 This application proposes a bulkhead support mechanism. The difference between this embodiment and Embodiment 1 is that there are two hinge portions 200, each including a flip portion 206, a hinge shaft 207, and a hinge seat 203. The two hinge portions 200 correspond to two supporting longitudinal beams 101 respectively. The flip portion 206 is fixedly connected to the rear end of the supporting longitudinal beam 101 and extends beyond the rear side of the support frame 100. The flip portion 206 has a shaft hole, and the hinge shaft 207 is fixedly connected to the hinge seat 203 and movably inserted into the shaft hole. Specifically, a support leg 400 is provided on the upper surface of the rear end of the supporting longitudinal beam 101, with one end of the support leg 400 extending to the rear side of the rear crossbeam 103. The flip portion 206 is located at the rear end of the support leg 400. Therefore, in this embodiment, the support frame 100 can also flip around the hinge shaft 207.

[0030] Furthermore, a support leg groove 401 is provided on the lower surface of the support leg 400; surface A, surface B and surface C are the three internal surfaces of the support leg groove 401; as shown in the figure, when surfaces A, B and C are in contact with the top crossbeam 300 of the end frame, the stability and rigidity of the support frame 100 can be maintained.

[0031] Example 4: Please refer to Figure 3 - Figure 5 This application provides a container, including a top platform 500 and four end frame corner posts 600, and also includes a bulkhead support mechanism as described in Embodiment 1. Specifically, the bulkhead support mechanism is located on one side of the top of the top platform 500, with a hinge 200 fixedly connected to the top surface of the top platform 500, and an end frame top crossbeam 300 installed between the tops of two end frame corner posts 600 near the bulkhead support mechanism. The hinge seat 203 of the hinge 200 is fixedly connected to the top surface of the top platform 500.

[0032] It is worth mentioning that, in practical applications of this embodiment, when several containers are stacked vertically, the support frame 100 can be flipped outwards to improve the stability of the containers, such as... Figure 3As shown in the diagram, wooden blocks or other pads are then placed between the support frame 100 and the bulkhead to ensure that the support frame 100 and the bulkhead are pressed together, thereby improving the stability of the container.

[0033] At the same time, for containers that are not adjacent to the bulkhead, the support frame 100 can be deployed and used to abut against the adjacent container, which can also improve stability.

[0034] Furthermore, the top platform 500 and the end frame corner post 600 are slidably fitted together, and the top platform 500 can be fixed to the top and bottom positions of the end frame corner post 600 respectively by locking mechanisms; and the end frame corner post 600 is composed of two sections, the top section and the bottom section are hinged together. When storage is required, the top platform 500 is moved to the bottom position of the end frame corner post 600, and then the top of the end frame corner post 600 is bent, as shown. Figure 5 The state shown is to reduce storage space.

[0035] In this embodiment, the container, under actual working conditions, such as Figure 3 As shown in the diagram, the top platform 500 is fixed at the top of the end frame corner post 600, and several containers are stacked vertically on top of each other. The space between the top platforms 500 of two vertically adjacent containers forms a storage space for placing items. Simultaneously, the top space of the topmost top platform 500 can also hold other items, further improving the space utilization of this embodiment.

[0036] Example 5: Please refer to Figure 8 and Figure 9 This application provides a container comprising a top platform 500 and four end frame corner posts 600, and also includes a bulkhead support mechanism as described in Embodiment 2. Specifically, the bulkhead support mechanism is located on one side of the top of the top platform 500, with a hinged portion 200 fixedly connected to the top surface of the top platform 500, and an end frame top crossbeam 300 installed between the tops of two end frame corner posts 600 near the side of the bulkhead support mechanism. Furthermore, a carabiner 205 is fixedly connected to the top surface of the top platform 500.

[0037] Example 6: Please refer to Figure 12 and Figure 13 This application provides a container, including a top platform 500 and four end frame corner posts 600, and also includes a bulkhead support mechanism as described in Embodiment 3. Specifically, the bulkhead support mechanism is located on one side of the top of the top platform 500, with a hinge 200 fixedly connected to the top surface of the top platform 500, and an end frame top crossbeam 300 installed between the tops of two end frame corner posts 600 near the bulkhead support mechanism. The hinge seat 203 of the hinge 200 is fixedly connected to the top surface of the top platform 500.

[0038] It should be noted that, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
