Description

Technical Field

[0001] The utility model belongs to the technical field of logistics transportation, and particularly relates to a bending-resistant corner post structure and a container. Background Technique

[0002] With the rapid development of the container market, the usage of containers has further expanded, which has led to an increasing variety of container types and usage conditions. At the same time, the requirements for the container structure and load-bearing capacity are also constantly changing. In practical applications, as the main load-bearing component of the container, the design of the corner post plays a decisive role in the load-bearing upper limit of the entire container. However, the existing corner post design is too simple, and when the container is fully loaded and lifted, the corner post often bends and deforms greatly due to poor bending resistance, failing to meet the load requirements of the usage conditions. Therefore, a new technical solution is urgently needed to solve the above problems. Summary of the Utility Model

[0003] One of the purposes of the utility model is to provide a bending-resistant corner post structure aiming at the deficiencies of the existing technology, so as to effectively improve the structural strength, bending resistance and structural stability of the product.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A bending-resistant corner post structure, the outer wall of the corner post structure includes a first bending-resistant part and a second bending-resistant part that are mutually enclosed and connected, the inner wall of the corner post structure includes first reinforcing rib plates connected to the opposite sides of the first bending-resistant part and second reinforcing rib plates connected to the opposite sides of the second bending-resistant part, and the first bending-resistant part, the first reinforcing rib plates, the second bending-resistant part and the second reinforcing rib plates all vertically extend along the height direction of the corner post structure.

[0006] As an improvement of the corner post structure of the utility model, the first reinforcing rib plates and the second reinforcing rib plates are arranged in parallel.

[0007] As an improvement of the corner post structure of the utility model, the mutually overlapping first reinforcing rib plates and second reinforcing rib plates are both opposite to the connection part of the first bending-resistant part and the second bending-resistant part. The mutually overlapping first reinforcing rib plates and second reinforcing rib plates can provide extremely strong bending resistance and improve the load-bearing performance of the corner post structure.

[0008] As an improvement of the corner post structure of the utility model, the first reinforcing rib plates and the second reinforcing rib plates are symmetrically spaced apart along the connection part of the first bending-resistant part and the second bending-resistant part. The symmetrically spaced-apart first reinforcing rib plates and second reinforcing rib plates can more flexibly adjust the bending resistance of the corner post structure.

[0009] As an improvement of the corner post structure of the present utility model, the first reinforcing rib plate and the second reinforcing rib plate sequentially divide the interior of the corner post structure into a first inner chamber, a second inner chamber and a third inner chamber, and the width of at least one of the first inner chamber and the third inner chamber is not less than the width of the second inner chamber, so as to ensure that the flexural strength of each inner chamber of the corner post structure can be adaptively adjusted within a reasonable range.

[0010] As an improvement of the corner post structure of the present utility model, the first reinforcing rib plate is perpendicular to the opposite sides of the first flexural resistance portion, and the second reinforcing rib plate is perpendicular to the opposite sides of the second flexural resistance portion, so as to effectively enhance the flexural strength and load-bearing performance of the corner post structure.

[0011] As an improvement of the corner post structure of the present utility model, the thickness of the first reinforcing rib plate is not less than the thickness of the first flexural resistance portion, and the thickness of the second reinforcing rib plate is not less than the thickness of the second flexural resistance portion, so as to effectively enhance the flexural strength and load-bearing performance of the corner post structure.

[0012] As an improvement of the corner post structure of the present utility model, the first flexural resistance portion, the first reinforcing rib plate, the second reinforcing rib plate and the second flexural resistance portion are all connected to a corner fitting. The corner fitting is provided with a connecting through groove perpendicular to the height direction of the corner post structure, and the connecting through groove is used for a lifting rope to pass through and tie the corner fitting tightly.

[0013] As an improvement of the corner post structure of the present utility model, both the first flexural resistance portion and the second flexural resistance portion have three sequentially connected continuous planes, and one of the three continuous planes is vertically and transitionally connected to the other two parallel continuous planes. The surfaces of the corner fitting located on both sides in the height direction of the corner post structure are both continuous planes. The corner fitting is connected to the first flexural resistance portion, the first reinforcing rib plate, the second reinforcing rib plate and the second flexural resistance portion through the continuous planes close to the first flexural resistance portion, the first reinforcing rib plate, the second reinforcing rib plate and the second flexural resistance portion, so as to ensure that the mutual connection has a sufficient contact area and ensure that the corner post structure has sufficient load-bearing performance.

[0014] The second object of the present utility model is to provide a container, which includes a box body and a plurality of corner post structures as described above, and each of the corner post structures is respectively arranged on the outer side wall of the box body.

[0015] The beneficial effects of the present utility model are as follows: The outer wall of the corner post structure of the present utility model includes a first bending-resistant portion and a second bending-resistant portion that are enclosed and connected to each other. The inner wall of the corner post structure includes a first reinforcing rib plate connected to opposite sides of the first bending-resistant portion and a second reinforcing rib plate connected to opposite sides of the second bending-resistant portion. The first bending-resistant portion, the first reinforcing rib plate, the second bending-resistant portion, and the second reinforcing rib plate all extend vertically along the height direction of the corner post structure. By the first reinforcing rib plate, the load-bearing capacity and bending-resistant capacity on both sides of the first bending-resistant portion are enhanced, and by the second reinforcing rib plate, the load-bearing capacity and bending-resistant capacity on both sides of the second bending-resistant portion are enhanced, so that the overall bending-resistant ability of the corner post structure is stronger and the structural strength is higher, enabling the corner post to meet the safety lifting requirements of the container.

[0025] The following combines the attached Figures 1 to 5 and specific embodiments to further elaborate on the present utility model in detail, but it is not a limitation on the present utility model.

[0026] Embodiment 1

[0027] An anti-bending corner post structure, see Figures 1 to 2, the outer wall of the corner column structure includes a first bending-resistant portion 1 and a second bending-resistant portion 2 that are enclosed and connected to each other. The two semi-frame-shaped first bending-resistant portion 1 and second bending-resistant portion 2 are buckled together to form an integral body. The inner wall of the corner column structure includes a first reinforcing rib plate 11 connected to the opposite sides of the first bending-resistant portion 1 and a second reinforcing rib plate 21 connected to the opposite sides of the second bending-resistant portion 2. The first reinforcing rib plate 11 and the second reinforcing rib plate 21 are respectively welded to the first bending-resistant portion 1 and the second bending-resistant portion 2. The first bending-resistant portion 1, the first reinforcing rib plate 11, the second bending-resistant portion 2, and the second reinforcing rib plate 21 all extend vertically along the height direction T1 of the corner column structure. By the first reinforcing rib plate 11, the load-bearing capacity and bending resistance of both sides of the first bending-resistant portion 1 are enhanced, and by the second reinforcing rib plate 21, the load-bearing capacity and bending resistance of both sides of the second bending-resistant portion 2 are enhanced, enabling the overall bending resistance of the corner column structure to be stronger and the structural strength to be higher.

[0028] Preferably, the first reinforcing rib plate 11 and the second reinforcing rib plate 21 are arranged in parallel, and the first reinforcing rib plate 11 and the second reinforcing rib plate 21 are symmetrically spaced apart along the connection of the first bending-resistant portion 1 and the second bending-resistant portion 2. Both the first bending-resistant portion 1 and the second bending-resistant portion 2 have a bending-resistant surface extending along the height direction T1 of the corner column structure.

[0029] Preferably, the first reinforcing rib plate 11 and the second reinforcing rib plate 21 sequentially divide the interior of the corner column structure into a first inner chamber 31, a second inner chamber 32, and a third inner chamber 33. The second inner chamber 32 is between the first inner chamber 31 and the third inner chamber 33. The first inner chamber 31 and the second inner chamber 32 are separated by the first reinforcing rib plate 11, and the second inner chamber 32 and the third inner chamber 33 are separated by the second reinforcing rib plate 21. The lengths of the first inner chamber 31, the second inner chamber 32, and the third inner chamber 33 are equal, and the width of at least one of the first inner chamber 31 and the third inner chamber 33 is not less than the width of the second inner chamber 32.

[0030] Specifically, the first reinforcing rib plate 11 is welded and fixed at 1 / 3 of the wide side of the side surface of the first bending-resistant portion 1. The long side of the side surface is the height side of the first bending-resistant portion 1. The first reinforcing rib plate 11 is at a distance of 1 / 3 of the length value of the wide side of the side surface of the first bending-resistant portion 1 from the connection of the first bending-resistant portion 1 and the second bending-resistant portion 2. This makes the stiffness of the corner column optimal and also facilitates processing and design.

[0031] Specifically, the second reinforcing rib plate 21 is welded and fixed at 1 / 3 of the wide side of the side surface of the second bending-resistant portion 2. The long side of the side surface is the height side of the second bending-resistant portion 2. The second reinforcing rib plate 21 is at a distance of 1 / 3 of the length value of the wide side of the side surface of the second bending-resistant portion 2 from the connection of the first bending-resistant portion 1 and the second bending-resistant portion 2. This makes the stiffness of the corner column optimal and also facilitates processing and design.

[0032] Specifically, in order to optimize the stiffness of the corner column, along the width direction T2 of the corner column structure, the width W1 of the first inner chamber 31 ≥ the width W2 of the second inner chamber 32, and the width W3 of the third inner chamber 33 ≥ the width W2 of the second inner chamber 32.

[0033] Preferably, the first reinforcing rib plate 11 is perpendicular to the opposite sides of the first bending-resistant part 1, the second reinforcing rib plate 21 is perpendicular to the opposite sides of the second bending-resistant part 2. Both the first bending-resistant part 1 and the second bending-resistant part 2 have three consecutive planes connected in sequence. One of the three consecutive planes is vertically transitionally connected to the other two parallel consecutive planes. Both the first bending-resistant part 1 and the second bending-resistant part 2 can be C-shaped sheet metal parts.

[0034] Preferably, the thickness of the first reinforcing rib plate 11 is not less than the thickness of the first bending-resistant part 1, the thickness of the second reinforcing rib plate 21 is not less than the thickness of the second bending-resistant part 2. The thicknesses of both the first reinforcing rib plate 11 and the second reinforcing rib plate 21 are at least greater than 40 mm - 80 mm.

[0035] Preferably, referring to Figure 3 , the first bending-resistant part 1, the first reinforcing rib plate 11, the second reinforcing rib plate 21, and the second bending-resistant part 2 are all connected to the corner fitting 4. The corner fitting 4 is provided with a connecting through groove 40 perpendicular to the height direction T1 of the corner column structure. The connecting through groove 40 is used for the lifting rope to pass through and tie the corner fitting 4 tightly. By lifting the corner fitting 4, the entire corner column structure can be stably lifted.

[0036] Preferably, the surfaces of both sides of the corner fitting 4 in the height direction of the corner column structure are continuous planes. The corner fitting 4 is connected to the first bending-resistant part 1, the first reinforcing rib plate 11, the second reinforcing rib plate 21, and the second bending-resistant part 2 through the continuous plane close to the first bending-resistant part 1, the first reinforcing rib plate 11, the second reinforcing rib plate 21, and the second bending-resistant part 2, so as to ensure that there is enough contact area at the connection position with each other, and ensure that the corner column structure has enough load-bearing performance.

[0037] Under the condition of full-load ceiling lifting of the container, referring to Figure 5 , the lifting rope is vertically lifted through at least four corner fittings 4. The center of gravity of the container is generally near its centroid. The four corner columns generate corresponding bending moments respectively due to the tensile force. The corner columns will undergo a certain amount of bending deformation under the action of the bending moment to offset the bending moment generated by the tensile force, and then corresponding concentrated stresses are generated on the corner columns. The first reinforcing rib plate 11 and the second reinforcing rib plate 21 added in this corner column can increase the stiffness of this corner column in the left-right direction, thereby reducing the bending deformation, and at the same time can disperse the force and reduce the stress concentration.

[0038] Embodiment 2

[0039] Referring to Figure 4, different from the separated arrangement of the first reinforcing rib plate 11 and the second reinforcing rib plate 21 in Embodiment 1, the inner wall of the corner post structure in this embodiment has a reinforcing support plate facing the connection between the first bending resistance portion 1 and the second bending resistance portion 2. The reinforcing support plate is at least formed by overlapping the first reinforcing rib plate 11 and the second reinforcing rib plate 21, and the overlapped first reinforcing rib plate 11 and second reinforcing rib plate 21 are both facing the connection between the first bending resistance portion 1 and the second bending resistance portion 2. In this way, although there are only two inner chambers inside the corner post structure, the overlapped first reinforcing rib plate 11 and second reinforcing rib plate 21 can provide extremely strong bending resistance for the corner post, effectively improving the load-bearing performance of the corner post structure.

[0040] Under the full-load ceiling condition of the container, refer to Figure 5 , the lifting ropes vertically lift through at least four corner fittings 4. The center of gravity of the container is generally near its centroid. The four corner posts generate corresponding bending moments due to the tensile force. Under the action of the bending moment, the corner posts will undergo a certain amount of bending deformation to offset the bending moment generated by the tensile force, and then corresponding concentrated stresses are generated on the corner posts. The additionally provided first reinforcing rib plate 11 and second reinforcing rib plate 21 inside this corner post can increase the stiffness of this corner post in the left-right direction, thereby reducing the bending deformation. At the same time, it can disperse the force and reduce the stress concentration.

[0041] Other structures of this embodiment are the same as those in Embodiment 1 and will not be elaborated here.

[0042] Embodiment 3

[0043] A container includes a box body and a plurality of corner post structures of Embodiment 1 or 2, and each corner post structure is respectively arranged on the outer side wall of the box body.

[0044] Compared with the existing cylindrical tube-shaped corner post structure, under the load lifting condition of the container, adopting the corner post structure of this solution, because the stiffness of the corner post increases, the bending resistance performance is better, the deflection deformation of the bottom cross beam is smaller, and the concentrated stress of the corner post is effectively improved, thereby improving the overall load-bearing capacity of the container.

[0045] According to the disclosure and teachings of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the above specific embodiments. Any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present invention all belong to the protection scope of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
