Description

A container corner

technical field

The invention relates to the field of containers, in particular to a container corner piece.

Background technique

As the main force-bearing parts of the container, the strength and performance of the corner parts of the container directly affect the service life of the container. For a long time, the corner parts of the container have been realized by casting, but the cast corner parts have the following disadvantages:

(1) The weight of the casted corner fittings is heavier: for the non-stressed surface of the corner fittings, the thickness is not optimal, resulting in the heavy weight of the casted corner fittings;

(2) The casting quality is uneven: the casting process is easy to cause defects, resulting in the substandard quality of the corner pieces, and it is difficult to check the casting defects;

(3) Energy saving and environmental protection issues: The energy consumption of casting is high, and a large amount of dust will be generated, which is not conducive to environmental protection and staff health.

Therefore, developing a container corner piece with high strength, light weight and low cost is a problem that needs to be solved.

Detailed ways

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other instances, some technical features known in the art have not been described in order to avoid obscuring the present invention.

FIG. 1 is a schematic structural diagram of a container corner fitting 10 according to Embodiment 1 of the present invention. As shown in FIG. 1 , the container corner piece 10 may include: a top plate 11 , a bottom plate 12 and a side wall 13 . The side wall 13 may be provided between the top plate 11 and the bottom plate 12 . The side wall 13 and the top plate 11 and the bottom plate 12 can be connected by welding. Said side wall 13 also comprises at least two parts welded together. Specifically, depending on the technological conditions, grooves for easy welding can be processed on each component. As a result, the use of welding methods (laser welding, machine welding and other technologies) avoids the common defects such as pores, sand inclusions, sand holes, and insufficient pouring of cast corner fittings, and improves the service life and safety of the corner fittings. At the same time, it also avoids a lot of dust and pollution generated by traditional casting methods, which is beneficial to the health of operators.

Correspondingly, the bottom plate 12 and the side wall 13 may be provided with through holes 14 . When the through hole 14 is formed on the side wall 13 , its strength will be reduced, so the inner side wall of the side wall 13 can be provided with a reinforcing plate 16 . The reinforcing plate 16 is also matched with a through hole 14 , which can pass through with the through hole 14 on the side wall 13 . The reinforcing plate 16 can be disposed on the inner side wall of the side wall 13 by welding or integral molding, so that the side wall 13 can have higher strength without having a thicker thickness, thereby reducing the overall weight of the container corner piece 10 , making it 10% - 40% lighter than traditional casting corner pieces. For example, the thickness of the top plate 11 and the side walls 13 may be 3-11 mm. The thickness of the bottom plate 12 is 12-28.5 mm, and the bottom plate 12 may also be provided with through holes 14 . The thickness of the side wall 13 (with the through hole 14 ) may be 3-11 mm, and the thickness of the reinforcing plate 16 may be 3-10 mm.

Further, in Example 1, the reinforcing plate 16 is provided in order to stably fix it. A notch 15 may be provided on the side of the top plate 11 corresponding to the reinforcing plate 16 . The shape of the notch 15 is adapted to the shape of the reinforcing plate 16 , so that the end of the reinforcing plate 16 can be clamped in the notch 15 , so that the reinforcing plate 16 can be stably arranged.

FIG. 2 is a schematic structural diagram of the container corner piece 10 provided in Embodiment 2. The difference from Embodiment 1 is that the top plate 11 in Embodiment 2 is not provided with a notch 15 . The top of the reinforcing plate 16 is flush with or lower than the top of the side wall 13 . The reinforcing plate 16 may be disposed on the side wall 13 by welding or integrally formed with the side wall 13 .

3 is a schematic structural diagram of the container corner fitting 10 provided in Embodiment 3. The difference from Embodiment 1 is that a plurality of notches 15 are formed on the side edges of the bottom plate 12 in Embodiment 3, thereby forming a stepped portion. The lower end of the side wall 13 can be disposed on and matched with the stepped portion, so as to be more stably welded to the bottom plate 12 .

FIG. 4 is a schematic structural diagram of the container corner piece 10 provided in Embodiment 4. The difference from Embodiment 1 is that the side wall 13 can be composed of two L-shaped metal pieces and two inner side walls that are respectively connected with the L-shaped metal pieces. Connected metal plates 132 are formed. For example, as shown in FIG. 4 , the L-shaped metal piece may include a bent piece 131 with a narrow width of the sidewall and an L-shaped metal piece disposed opposite to each other. More specifically, the structure of the L-shaped metal piece includes a first plate extending in the length direction of the container corner piece and a second plate extending in the width direction of the container. The thickness of the metal plate 132 is greater than the thicknesses of the L-shaped metal piece and the bending piece 131 with a narrow width. The metal plate 132 may be provided with a through hole 14 . Since the thickness of the metal plate 132 forming the side wall 13 is relatively thick, and the thickness may be 5-20.5 mm, the reinforcing plate 16 may not be provided. The side edges of the bottom plate 12 and the top plate 11 are provided with notches 15 which are adapted to this structure. Specifically, the thickness of the top plate 11 , the side walls 13 and the small side walls may be 3-11 mm, and the thickness of the bottom plate 12 may be 12-28.5 mm.

5 and 6 are schematic structural diagrams of the container corner piece 10 provided in Embodiment 5, which is different from Embodiment 1 in that the side wall 13 is formed by combining two L-shaped metal parts, one of which can be made of Two thick metal plates 132 are formed. The thickness of the metal plate 132 is relatively thick, so that the reinforcing plate 16 may not be provided. Wherein, the two metal plates 132 can be directly welded or connected by a connecting piece to form two side surfaces of the corner piece. Specifically, the thickness of the top plate 11 and the side wall 13 may be 3-11 mm. , the thickness of the metal plate 132 may be 5-20.5mm. The thickness of the base plate 12 may be 12-28.5mm.

In the above-mentioned embodiment, in order to ensure the strength of the container corner piece 10 . The material used for the container corner fittings 10 may have a yield strength >275 MPa, and may use high-strength steel or micro-alloy steel, or a combination of several steels with different yield strengths (such as SPA-H or a combination of high-strength steel).
