Description

Container side wall and container

Technical Field

The utility model belongs to the field of containers, and particularly relates to a container side wall and a container.

Background

The stress distribution of the different component parts of the bulk container is different during the transportation of the goods. Generally speaking, bulk cargo in the box generates larger concentrated load on the middle part of the side wall of the box, and larger stress is generated on the middle part of the side wall of the box, so that higher requirements are placed on the strength of the middle part of the side wall of the box.

The container in the prior art generally has side plates with the same thickness or a uniform side wall structure matched with reinforcing components which are uniformly distributed, and the structure has the following defects: the end parts of the side walls are connected with the corner posts, so that the end parts of the side walls are not easy to deform, the middle parts of the side walls are weak in strength, and the opposite end parts of the side walls often bear larger concentrated loads, so that the problem that the bulk container is expanded, and particularly the middle parts of the side walls are deformed in the process of transporting goods can be caused; the container meeting the strength requirement of the middle part of the side wall has the defects of large weight, large material consumption, high manufacturing cost and high operation cost because the side wall end parts of the uniform side wall structure are basically the same as the structure of the middle part of the side wall.

To this end, the present utility model provides a container sidewall and container to at least partially address the above-mentioned problems.

Disclosure of utility model

In the summary, a series of concepts in a simplified form are introduced, which will be further described in detail in the detailed description. The summary of the utility model is not intended to limit the critical and essential features of the claimed subject matter, nor is it intended to be used to determine the scope of the claimed subject matter.

To at least partially solve the above problems, a first aspect of the present utility model provides a container side wall for connecting to two corner posts on the same side of a container, the container side wall comprising:

According to the container side wall, as the two end side wall parts are respectively connected with the corner posts, the end side wall parts are not easy to deform, the strength of the middle part of the side wall (namely the middle side wall part) is weaker, and the middle part of the side wall is easy to deform relative to the end side wall parts to bear larger concentrated load, so that the container is kept stable and does not expand in the transportation process, the strength requirement of the middle side wall part is larger than that of the opposite end side wall part, namely the strength requirement of the middle side wall part is met, and meanwhile, the strength requirement of the opposite end side wall part is reduced, so that the concentrated load transportation requirement is met, the container expansion is prevented, the self weight of a container body is reduced, the load carrying weight is increased, the material is saved, the manufacturing process is simplified, the manufacturing cost is reduced, and the pain point in the industry is solved. Moreover, since the number of the end side wall portions is two, the effects of reducing the weight of the box body and increasing the weight of the load are more remarkable. And the distance between each of the two ends of the middle side wall part along the length direction and the central line of the container side wall is greater than 1/8 of the dimension of the container side wall along the length direction. Therefore, the middle side wall part is ensured to have enough length so as to ensure the overall strength of the middle side wall part, prolong the service life of the container side wall and reduce the operation cost on the whole.

Optionally, the container side wall further comprises two or more spaced apart reinforcing portions, the reinforcing portions being disposed at a greater density in the central side wall portion than in the end side wall portions.

Alternatively, the process may be carried out in a single-stage,

Fig. 1 to 11 show a container side wall according to the utility model.

Fig. 1, 2 and 3 show a first embodiment of a container side wall 100. A first aspect of the utility model provides a container side wall 100 for connection to two corner posts on the same side of a container, the container side wall 100 comprising an end side wall portion 110 and a middle side wall portion 130. The two end side wall portions 110 are respectively for connection to two corner posts. The middle side wall portion 130 is connected between the two end side wall portions 110 along the longitudinal direction D1 of the container. Wherein the strength of the middle side wall portion 130 is greater than the strength of the end side wall portion 110, and the distance between each of the two ends of the middle side wall portion 130 in the longitudinal direction D1 and the center line of the container side wall 100 is greater than 1/8 of the dimension of the container side wall 100 in the longitudinal direction D1.

According to the container side wall, as the two end side wall parts are respectively connected with the corner posts, the end side wall parts are not easy to deform, the strength of the middle part of the side wall (namely the middle side wall part) is weaker, and the middle part of the side wall is easy to deform relative to the end side wall parts to bear larger concentrated load, so that the container is kept stable and does not expand in the transportation process, the strength requirement of the middle side wall part is larger than that of the opposite end side wall part, the strength requirement of the middle side wall part is met, and meanwhile, the strength requirement of the opposite end side wall part is reduced, so that the concentrated load transportation requirement is met, the container expansion is prevented, the self weight of a container body is reduced, the load carrying weight is increased, the material is saved, the manufacturing process is simplified, the manufacturing cost is reduced, and the pain point in the industry is solved. Moreover, since the number of the end side wall portions is two, the effects of reducing the weight of the box body and increasing the weight of the load are more remarkable. And the distance between each of the two ends of the middle side wall part along the length direction and the central line of the container side wall is greater than 1/8 of the dimension of the container side wall along the length direction. Therefore, the middle side wall part is ensured to have enough length so as to ensure the overall strength of the middle side wall part, prolong the service life of the container side wall and reduce the operation cost on the whole.

The directional terms used for each component, portion, etc. of the container described in the present utility model are relative to the container in the horizontally placed and erected state, and "longitudinal direction", "width direction", and "height direction" each correspond to the "longitudinal direction", "width direction", and "height direction" of the container, and "inside" is the inside of the container, and "outside" is the outside relative to the inside of the container.

In this embodiment, both ends of the container side wall 100 in the longitudinal direction D1 are respectively for connection to two corner posts on the same side of the container, and the upper portion of the container side wall 100 is for connection to the top side member 11 of the container. The container sidewall 100 may include an end sidewall portion 110, a middle sidewall portion 130, and a reinforcement portion 140.

The strength of the middle side wall part 130 is greater than that of the end side wall part 110, namely, the strength requirement of the opposite end side wall part 110 can be reduced while the strength of the middle side wall part 130 is met, so that the container can be prevented from expanding, the self weight of the container body is reduced, the cargo weight is increased, materials are saved, the manufacturing process is simplified, the manufacturing cost is reduced, and the pain point of the industry is solved. Further, the rigidity of the middle side wall portion 130 may be greater than the rigidity of the end side wall portion 110, i.e., the rigidity requirement of the end side wall portion 110 may be reduced while the rigidity of the middle side wall portion 130 is satisfied.

In some preferred embodiments, each of the two ends of the middle sidewall portion 130 in the length direction D1 may be spaced from the center line of the container sidewall 100 by a distance greater than 1/6 of the dimension of the container sidewall 100 in the length direction D1. Further preferably, both ends of the middle side wall portion 130 in the length direction D1 may each be spaced apart from the center line of the container side wall 100 by a distance greater than 1/5 of the dimension of the container side wall 100 in the length direction D1. Therefore, the middle side wall part is ensured to have longer length, so that the overall strength of the middle side wall part is ensured, and the service life of the container side wall is prolonged.

In some embodiments, the distance between each of the two ends of the middle sidewall portion 130 along the length direction D1 and the center line of the container sidewall 100 may be less than 5/12 of the dimension of the container sidewall 100 along the length direction D1, so that the two end sidewall portions 110 have a certain size, which further improves the effects of reducing the self weight of the container body and increasing the weight of the cargo, and saves the cost.

In some preferred embodiments, the distance between each of the two ends of the middle sidewall portion 130 in the length direction D1 and the center line of the container sidewall 100 may preferably be greater than 1/8 of the dimension of the container sidewall 100 in the length direction D1 and less than 5/12 of the dimension of the container sidewall 100 in the length direction D1. The distance between each of the both ends of the middle side wall portion 130 in the longitudinal direction D1 and the center line of the container side wall 100 may further preferably be greater than 1/6 of the dimension of the container side wall 100 in the longitudinal direction D1 and less than 5/12 of the dimension of the container side wall 100 in the longitudinal direction D1.

It can be appreciated that the length of the middle sidewall portion 130 and the end sidewall portion 110 can be flexibly adjusted according to specific working conditions and actual requirements based on meeting strength requirements. For example, in some embodiments, one end of the middle sidewall portion 130 in the length direction D1 may be spaced from the centerline of the container sidewall 100 by a distance greater than 1/6 of the dimension of the container sidewall 100 in the length direction D1, while the other end of the middle sidewall portion 130 in the length direction D1 may be spaced from the centerline of the container sidewall 100 by a distance greater than 1/8 but less than or equal to 1/6 of the dimension of the container sidewall 100 in the length direction D1. For another example, in some embodiments, one end of the middle sidewall portion 130 in the length direction D1 may be spaced from the centerline of the container sidewall 100 by a distance greater than 1/5 of the dimension of the container sidewall 100 in the length direction D1, while the other end of the middle sidewall portion 130 in the length direction D1 may be spaced from the centerline of the container sidewall 100 by a distance greater than 1/8 but less than or equal to 1/5 of the dimension of the container sidewall 100 in the length direction D1, while the two ends of the middle sidewall portion 130 in the length direction D1 may each be spaced from the centerline of the container sidewall 100 by a distance less than 5/12 of the dimension of the container sidewall 100 in the length direction D1.

In some embodiments, the middle sidewall portion 130 may be connected between the two end sidewall portions 110 along the length direction D1 of the container by a weld. Specifically, one or both ends of the middle side wall portion 130 in the length direction D1 of the container are welded between the two end side wall portions 110 such that there is a weld between the middle side wall portion 130 and the end side wall portion 110 for welding the middle side wall portion 130 and the end side wall portion 110. Taking an example in which the two ends of the middle side wall portion 130 along the length direction D1 of the container are welded between the two end side wall portions 110, the two ends of the middle side wall portion 130 along the length direction D1 are each spaced from the center line of the container side wall 100 by a distance greater than 1/8 of the dimension of the container side wall 100 in the length direction D1, that is, the distance between the weld joint and the center line of the container side wall 100 is greater than 1/8 of the dimension of the container side wall 100 in the length direction D1. As can be appreciated, the weld seam used to weld the side wall portion 130 to the end side wall portion 110 is farther from the location on the container side wall 100 that is subject to the greater concentrated load (i.e., the centerline or vicinity of the centerline of the container side wall 100), thereby effectively reducing the risk of weld seam cracking, increasing the service life of the container side wall 100, and reducing the operating costs as a whole. If needed and/or desired, one end of the middle side wall portion 130 in the length direction D1 of the container is welded to the end side wall portion 110 corresponding to the one end, and the other end of the middle side wall portion 130 in the length direction D1 is integrally provided with the end side wall portion 110 corresponding to the other end, for example, constructed as a one-piece plate.

In other embodiments, the middle sidewall portion 130 and the two end sidewall portions 110 may be integrally provided, and may be specifically configured as a one-piece plate.

It will be appreciated that in the above embodiment in which the intermediate side wall portion 130 is connected between the two end side wall portions 110 by a weld along the longitudinal direction D1 of the container, the respective ends of the intermediate side wall portion 130 along the longitudinal direction D1 may each be spaced from the center line of the container side wall 100 by a distance greater than 1/6 of the dimension of the container side wall 100 in the longitudinal direction D1, i.e., the weld connecting the intermediate side wall portion 130 and the end side wall portion 110 may be spaced from the center line of the container side wall 100 by a distance greater than 1/6 of the dimension of the container side wall 100 in the longitudinal direction D1. Further preferably, each of both ends of the middle side wall portion 130 in the length direction D1 may be spaced apart from the center line of the container side wall 100 by a distance greater than 1/5 of the dimension of the container side wall 100 in the length direction D1, i.e., the weld joining the middle side wall portion 130 and the end side wall portion 110 may be spaced apart from the center line of the container side wall 100 by a distance greater than 1/5 of the dimension of the container side wall 100 in the length direction D1. That is, the weld is further from the location on the container sidewall 100 that is subject to the greater concentrated load (i.e., the centerline or vicinity of the centerline of the container sidewall 100), thereby further reducing the risk of weld cracking.

Referring to fig. 2 and 3, the thickness of the middle sidewall portion 130 is greater than the thickness of the end sidewall portion 110. For example, for the middle side wall portion 130 and the end side wall portion 110 made of the same material, the strength requirement of the opposite end side wall portion 110 can be reduced while the strength of the middle side wall portion 130 is satisfied, specifically, the thickness of the end side wall portion 110 can be reduced while the thickness of the middle side wall portion 130 is satisfied, so that the self weight of the box body is reduced, the cargo weight is increased, the material is saved, and the cost is reduced. In some embodiments, the middle sidewall portion 130 protrudes from the end sidewall portion 110 toward the interior of the container in the width direction D3. The thickness of the middle sidewall 130 and the thickness of the end sidewall 110, and the difference or ratio thereof can be adjusted according to the actual working conditions and the use requirements.

Generally, in a bulk container during loading and unloading, the end side wall portion 110 near the door end of the container is subjected to a concentrated load more than the end side wall portion 110 near the front end of the container, whereby the strength of the end side wall portion 110 near the door end of the container can be further made stronger than the strength of the end side wall portion 110 near the front end of the container, and in particular, the thickness of the end side wall portion 110 near the door end of the container can be made thicker than the thickness of the end side wall portion 110 near the front end of the container.

In the present embodiment, the end side wall portion 110 and the middle side wall portion 130 are each constructed as a flat plate, and the cost is low.

Optionally, two or more reinforcements 140 are provided on the container side wall 100 at intervals. The provision of the reinforcement 140 may further increase the robustness of the container sidewall 100, making it more durable and longer-lived. In some embodiments, two or more reinforcing portions 140 may be uniformly spaced on the middle sidewall portion 130 of the container sidewall 100. In some embodiments, two or more reinforcing portions 140 may be uniformly spaced on the end sidewall portion 110 of the container sidewall 100. In other embodiments, the distance between two adjacent reinforcing portions 140 is not particularly limited, and may be adjusted according to actual usage requirements.

The reinforcement 140 may extend in the height direction D2 of the container. The dimension of the reinforcement portion 140 in the height direction D2 may be the same as the dimension of the container side wall 100 in the height direction D2, or may be different from the dimension of the container side wall 100 in the height direction D2. The specific size can be flexibly set according to the actual working condition of the strength and the use requirement. The cross section of the reinforcement 140 may be corrugated, the cross section of the reinforcement 140 may be flat, and the reinforcement 140 may be shaped to fit the side walls of the container. The shape, size, material, etc. of the reinforcement portion 140 are not particularly limited. Specifically, in some embodiments, the reinforcement portion 140 may be an upright post or a C-shaped beam, so that the manufacturing process of the container sidewall 100 of the present utility model is simple, and has good market utility value.

In some embodiments, the reinforcement 140 may be disposed outside of the sidewall, thereby not occupying the interior space. In other embodiments, the reinforcement 140 may also be disposed within the interior of the side walls, whereby the reinforcement 140 may disperse, for example, partial impacts of the cargo carried by the bulk container, thereby reducing impacts on the side wall bodies of the container (i.e., the middle side wall portion 130 and the end side wall portion 110) during transportation, thereby reducing damage to the side wall bodies of the container, increasing the service life of the container side wall 100, and thereby increasing the service life of the container.

Fig. 4, 5 and 6 show a second embodiment of a container sidewall 300. In the second embodiment, unlike the first embodiment, the end side wall portion 210 and the middle side wall portion 230 are each constructed of a corrugated plate, and are sturdy and durable. In the present embodiment, the reinforcing portion 140 may be provided as in the first embodiment, or the reinforcing portion 140 may not be provided.

Referring to fig. 5 and 6, as in the first embodiment, the thickness of the middle side wall portion 230 is greater than the thickness of the end side wall portion 210. In some embodiments, the waveforms of the middle sidewall portion 230 and the end sidewall portion 210 may be substantially the same, and in other embodiments, the waveforms of the middle sidewall portion 230 and the end sidewall portion 210 may be different. The waveforms of the two end side wall portions 210 may be the same or different. As shown in fig. 6, at the junction of the intermediate side wall portion 230 and the end side wall portion 210, the intermediate side wall portion 230 protrudes from the end side wall portion 210 toward the inside of the container in the width direction D3.

The remaining non-illustrated portions of the second embodiment are referred to in the description of the first embodiment and the accompanying drawings, which will not be described and/or illustrated in detail for the sake of brevity.

Fig. 7 and 8 show a third embodiment of a container sidewall 300. Unlike the first embodiment, the container sidewall 300 further includes two or more reinforcement parts 340 disposed at intervals in the third embodiment, and the reinforcement parts 340 are disposed at a greater density in the middle sidewall part 330 than in the end sidewall part 310. Therefore, the strength requirement of the opposite end side wall part 310 can be reduced while the strength of the middle side wall part 330 is satisfied, and particularly, the setting density of the reinforcing part 340 of the end side wall part 310 can be reduced while the setting density of the reinforcing part 340 of the middle side wall part 330 is satisfied, thereby reducing the self weight of the box body, increasing the loading weight, saving materials and reducing the cost.

In some embodiments, the thickness of the middle sidewall portion 330 may be greater than the thickness of the end sidewall portion 310, further increasing the strength of the middle sidewall portion 330 to enable it to withstand greater loads. In other embodiments, the thickness of the middle sidewall portion 330 may be equal to the thickness of the end sidewall portion 310, and the manufacturing process is simple and practical.

The reinforcement 340 may include a first reinforcement provided at the middle sidewall part 330 and a second reinforcement provided at the end sidewall part. Specifically, in some embodiments, the first reinforcing portions are uniformly disposed at the middle sidewall portion 330 and the second reinforcing portions are uniformly disposed at the end sidewall portion 310, with the distance between two adjacent first reinforcing portions being less than the distance between two adjacent second reinforcing portions.

Similar to the first embodiment, since the end side wall portion 310 near the door end of the container out of the two end side wall portions 310 receives a larger concentrated load than the end side wall portion 310 near the front end of the container in the course of loading and unloading, the strength of the end side wall portion 310 near the door end of the container can be further made larger than the strength of the end side wall portion 310 near the front end of the container, and in the present embodiment, the arrangement density of the second reinforcement portion of the end side wall portion 310 near the door end of the container is made larger than the arrangement density of the second reinforcement portion of the end side wall portion 310 near the front end of the container.

Specifically, in some embodiments, the second reinforcement portions are uniformly disposed at the end side wall portion 310 near the door end, the second reinforcement portions are uniformly disposed at the end side wall portion 310 near the front end, and the distance between two adjacent second reinforcement portions on the end side wall portion 310 near the door end is smaller than the distance between two adjacent second reinforcement portions on the end side wall portion 310 near the front end.

The remaining non-illustrated portions of the third embodiment are referred to the descriptions and/or illustrations of the first and second embodiments, which will not be described and/or illustrated in detail for the sake of brevity.

Fig. 9, 10 and 11 show a fourth embodiment of a container side wall 400. Unlike the third embodiment, in the fourth embodiment, each of the end side wall portion 410 and the middle side wall portion 430 is constructed as a corrugated plate including a first flat plate 431, a second flat plate 432, and inclined connection plates 433 between the first flat plate 431 and the second flat plate 432, the first flat plate 431 being closer to the inside of the container than the second flat plate 432, and the reinforcing portion 440 being connected to two adjacent inclined connection plates 433.

As shown in fig. 10 and 11, the end side wall part 410 and the middle side wall part 430 may be constructed as corrugated plates including a first flat plate 431, a second flat plate 432, and inclined connection plates 433 between the first flat plate 431 and the second flat plate 432, the first flat plate 431 being closer to the inside of the container than the second flat plate 432, and the reinforcement 440 being connected to two adjacent inclined connection plates 433. Thereby, the reinforcement 440 is provided for connection (e.g., welding) thereto.

In some embodiments, the reinforcing portion 440 is connected to two adjacent inclined connection plates 433 connected to the same second plate 432, in other words, the reinforcing portion 440 is received in a receiving space formed by the second plate 432 and the two inclined connection plates 433 connected to both ends of the second plate 432, i.e., the reinforcing portion 440 is disposed inside the container, whereby the reinforcing portion 440 can disperse a partial impact of, for example, cargo carried by the bulk container, thereby reducing the impact of the container's sidewall body (i.e., the middle sidewall portion 430 and the end sidewall portion 410) during transportation, thereby reducing damage to the container's sidewall body, improving the service life of the container's sidewall 400, and thus improving the service life of the container. In some not shown embodiments, the reinforcement 440 is connected to two adjacent inclined connection plates 433 connected to the same first flat plate 431, in other words, the reinforcement 440 is received in a receiving space formed by the first flat plate 431 and the two inclined connection plates 433 connected to both ends of the first flat plate 431, i.e., the reinforcement 440 is disposed outside the container, thereby not occupying an inner space of the container.

The reinforcement 440 preferably does not exceed the range defined by the first plate 431 and the second plate 432 in the width direction D3 of the container, thereby occupying no additional space and being more beautiful.

In some embodiments, the cross section of the reinforcing portion 440 is flat plate-shaped, which is simple in structure and low in cost. In other embodiments, the cross-section of the stiffening portion 440 is corrugated, and may have a wave. The wave trough of the corrugated reinforcing portion 440 is disposed opposite to the first plane of the reinforcing portion 440, and the reinforcing effect of the corrugated reinforcing portion 440 is better.

Alternatively, when both the end side wall portion 410 and the middle side wall portion 430 are constructed as corrugated plates, the reinforcement portion is connected to two adjacent inclined connection plates 433 connected to the same second flat plate 432. The provision of the reinforcing portion 440 may further enhance the robustness of the corrugated plate used for the container sidewall 400, making it more durable and longer in service life.

In some embodiments, the reinforcing portion 440 may be provided only on the middle sidewall portion 430, that is, the end sidewall portion 410 may not be provided with the reinforcing portion 440 to satisfy the strength requirement. In other examples, the reinforcing portions 440 may be uniformly disposed at the middle sidewall portion 430, and the reinforcing portions 440 may be uniformly disposed at the end sidewall portion 410, and the reinforcing portions 440 may be disposed at a greater density at the middle sidewall portion 230 than at the end sidewall portion 410, similar to the third embodiment.

Similar to the third embodiment, in particular, in some examples, the first reinforcing portions are uniformly disposed at the middle side wall portion 430, the second reinforcing portions are uniformly disposed at the end side wall portion 410, and the distance between two adjacent first reinforcing portions is smaller than the distance between two adjacent second reinforcing portions.

Similar to the third embodiment, since the end side wall portions 410 near the door end of the container among the two end side wall portions 410 receive a larger concentrated load than the end side wall portions 410 near the front end of the container in the course of loading and unloading of the bulk cargo container, the strength of the end side wall portions 410 near the door end of the container can be further made larger than the strength of the end side wall portions 410 near the front end of the container, and in the present embodiment, the arrangement density of the second reinforcement portions of the end side wall portions 410 near the door end of the container is made larger than the arrangement density of the second reinforcement portions of the end side wall portions 410 near the front end of the container. It will be appreciated that the second reinforcement portion of the end side wall portion 410 near the front end of the container may be provided at a density of 0, i.e., no second reinforcement portion is provided.

The remaining non-illustrated portions of the fourth embodiment refer to the descriptions and illustrations of the first, second, and third embodiments, which are not described and/or illustrated in detail for the sake of brevity.

The middle side wall portion and the end side wall portion of the present utility model may be made of a metal material suitable for welding, such as stainless steel, stainless iron, aluminum alloy, or the like.

In some embodiments, not shown, the configuration of the end and middle sidewall portions may differ from the illustrated embodiments. In some implementations, the middle sidewall portion may have both a greater thickness and a greater placement density of reinforcement portions relative to the end sidewall portion. In some implementations, the end sidewall portions are flat plates and the middle sidewall portions are corrugated plates, with or without reinforcement. The specific embodiment can be adjusted according to the actual requirements.

A second aspect of the utility model provides a container. The container comprises a container side wall of any of the above aspects. Both ends of the container side wall in the length direction D1 are connected to two corner posts on the same side of the container, respectively, and the upper portion of the container side wall is connected to the top side sill 11 of the container.

It will be appreciated that the container according to the utility model includes all of the features and effects of the container side walls according to the utility model.
