CN201089606Y - Hoisting and stowage structure of container - Google Patents

Abstract

The utility model relates to a hoisting and stacking structure for containers, comprising a corner post, as well as a top corner part and a bottom corner part which are respectively positioned on the top and the bottom of the corner post, wherein, a first ear extending downwards is arranged on the top corner part; a second ear extending upwards is arranged on the bottom corner part; the first ear and the second ear both stretch into the corner post and are welded together with the inner surface of the corner post. The hoisting and stacking structure for containers increases the welding seam length between the corner post and the top corner part as well as the bottom corner part, thereby strengthening the connection among the three. As the fit of the first ear and the second ear with the corner post is just the simple fit of one plane with the other plane, the problem of incomplete assembly cannot occur, and even if the precision of the top corner part and the bottom corner part with the ears is reduced, the assembly with the corner post cannot be affected. Therefore, the assembly technology problems caused by corner part errors are avoided, ensuring that the assembly of the corner parts with ears and the corner post is simpler and more convenient.

Description

Container lifting and stacking structure

technical field

The utility model relates to the field of containers, in particular to a container lifting and stacking structure.

Background technique

Traditional containers are manufactured according to the size requirements of the ISO standard. The width of the box body is 2438mm. When lifting with the corner fittings on the top of the box, the center distance of the lifting and stacking holes is 2260mm. However, in recent years, some ultra-wide boxes that have appeared in North America or Europe have a box width of 2591mm or even 2600mm. In order to use the existing ISO lifting equipment, the lifting and stacking center distance of the supporting corner parts is still required to be 2260mm. As a result, the bending moment M suffered by the corner fittings under the action of the lifting force F and the weight G of the box increases, which puts forward higher requirements for the strength of the weld at the joint between the corner fittings and the corner columns. As shown in Figures 1 and 2, comparing the connection methods of corner fittings and corner posts of traditional ISO containers and ultra-wide boxes, under the condition of a certain lifting hole center distance W, the wider the box width, the distance between the lifting force F and the gravity G The larger it is, that is, d2>d1, the greater the bending moment on the top corner piece, that is, M2>M1, and the weld between the corner piece and the corner post is more likely to be damaged.

In order to ensure the safety of transportation, the method of increasing the length of the weld between the corner post and the corner fitting can be adopted, so as to improve the reliability of the connection between the corner fitting and the corner post in the ultra-wide box. As shown in Figures 3-8, in the prior art, corner fittings 1 and 2 with ears 21 are welded to corner posts 3, and small bosses 22 are integrally provided on the ears 21. When assembling, not only the corner fitting ear 21 is inserted into the corner post 3, but also the gap 23 on the corner post 3 is welded by the small boss 22, which prolongs the length of the weld between the corner fittings 1, 2 and the corner post 3, greatly improving the The connection strength between the corner fittings 1, 2 and the corner post 3 also reduces the influence of the bending moment, thereby effectively ensuring the reliability of the connection between the two.

In the prior art, the connection method between the corner fittings 1, 2 and the corner post 3 is widely used because of its high reliability, but in the actual production process of the container, the assembly method of the corner fittings 1, 2 and the corner post 3 is difficult in the process. There are often some problems. Because the corner pieces 1 and 2 are all castings, the precision is not high, and due to the technical requirements of the casting itself, a larger process fillet will appear at the intersection 24 of the corner piece ear 21 and the small boss 22 . Due to the presence of rounded corners, when the corner fittings 1 and 2 are assembled with the corner post 3, the inner surface 25 of the corner post 3 cannot be well attached to the outer surface of the ear 21, and the end 26 of the corner post 3 cannot reach the corner fitting surface 27. However, it cannot meet the requirements of the assembly process. If the notch 23 of the corner post is enlarged so as to avoid rounded corners during assembly, the weld seam 28 will be very thick, the welding appearance will be ugly, and the welding quality cannot be guaranteed. Sometimes, due to the casting, the corner fitting ear 21 is not centered, and even the corner fitting ear 21 cannot be matched with the corner post gap 23 at all.
