A kind of gooseneck groove, the manufacturing method of gooseneck groove, container underframe and container

Abstract

The invention discloses a gooseneck groove. The gooseneck groove comprises a top plate, bent side walls downwards extending from two sides of the top plate and wing plates outwards extending from the bent side walls, wherein the width of the wing plates is greater than or equal to 50 mm, and the specific value of the heights of the bent side walls and the widths of the wing plates is smaller than or equal to 3.4. The invention further discloses a container base frame. The container base frame comprises any gooseneck groove. One end of the gooseneck groove in the length direction is connected with a bottom end beam of the container base frame. The invention further discloses a container. The container comprises the container base frame. In addition, the invention further discloses a gooseneck groove manufacturing method. The gooseneck groove manufacturing method adopts plates to manufacture any gooseneck groove. The gooseneck groove, the container base frame and the container are large in strength, high in anti-residual deformation capacity, good in durability, low in production cost and long in service life.

Description

technical field [0001] The present invention relates to a support, in particular to a support for a container. Background technique [0002] As a large-scale freight equipment, the container has developed into a multimodal international transportation tool in the 1960s. At present, the container usually adopts a hollow box structure, which is mainly formed by a pair of side walls, a door end, a front end, a top plate and a bottom frame, and the goods to be transported are loaded in the box. The chassis is the main load-bearing part of the container. In order to match the gooseneck structure of the gooseneck chassis, larger containers (for example, containers above 40 feet) are usually provided with a gooseneck groove at the front end of the chassis. figure 1 The structure of the existing gooseneck is shown. Such as figure 1 As shown, the gooseneck groove 10 includes a top plate 101 and side walls 102 extending downward and outward along the two sides of the top plate 101...

AI Technical Summary

Problems solved by technology

[0003] However, the existing gooseneck grooves have the following problems: After long-term loading and unloading of goods by forklifts, the residual deformation of the gooseneck grooves is found to accumulate continuously and exceed the standard. Poor capacity and insufficient durability, which directly affects the service life of the container

However, the disadvantages of these two improvement methods are: 1) lead to a great increase in production cost, 2) can only slightly improve the residual deformation resistance of the gooseneck groove

The gooseneck groove obtained by the above improved method cannot meet the core demands of customers and is difficult to be accepted by customers
