Description

[Detailed description of the invention] [Industrial application field] The present invention relates to containers for transporting liquid cargo, so-called tank containers, which have excellent strength, reduce weight and cost by reducing the number of parts used and manufacturing steps. Furthermore, the present invention relates to a tank container that can be easily used as a heat-insulating container by easily wrapping a heat insulating material or the like around the outer circumference of the tank.

[Conventional technology]

Conventionally, most of the tank containers provided are supported within a rectangular parallelepiped frame that surrounds the tank, and corner fittings are provided at the corners of the frame so that they can be stacked and handled in the same way as dry containers. There is.

The tank can be supported using a saddle method in which the lower part of the tank is supported within the frame, a method in which both ends of the tank (end plates) are fixed to the frame, a method in which a band is used together with the saddle, and a combination of the above methods. methods have been adopted.

[Problem that the invention attempts to solve]

In the above-mentioned saddle type, stress concentration tends to occur because the two parts at the bottom of the tank and the bottom of the frame are integrated, and various parts are required to avoid this, making it impossible to reduce weight and cost. ,
It was also difficult to wrap insulation materials, etc.

Further, the method of fixing both ends of the tank to the frame is not preferable because both ends of the tank are fixed by two-point support, which causes a large force to be applied to the tank body plate.

Other methods require a large number of members, and therefore have the disadvantage that it is time-consuming to wrap the heat insulating material, etc., after fixing the tank.

The present invention supports predetermined positions on both ends of the tank that are suitable for stabilizing the tank, and utilizes a vacuum-resistant reinforcing ring formed around the outer periphery of the tank.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a plurality of vacuum-resistant reinforcing rings at appropriate intervals around the outer circumference of the tank, and a plurality of vacuum-resistant reinforcing rings are provided at both ends of the tank. At least two support plates each extend to the reinforcing frame constituting the frame, and the outer peripheral ends of the supporting plates are welded to the reinforcing frame.

[Effect]

According to the present invention, the tank a is fixed and supported by the frame b using the vacuum-resistant reinforcing rings 1 and 1c provided at both ends as support plates 6.

Therefore, the force is applied evenly to the tank shell, the force is distributed, the durability is improved, and further parts can be saved.

Furthermore, since the support plate 6 does not resist deformation of the tank a in the longitudinal direction, the frame b will not be deformed even if the length of the tank a changes due to, for example, hot liquid. In addition, the above-mentioned vacuum-resistant reinforcing rings 1 and 1c
Since the fixation and support at the part are performed in the circumferential direction of the tank a, it becomes a brim shape, and does not get in the way even when wrapping a heat insulating material or the like.

〔Example〕

In the drawings, a is a tank and b is a frame, which constitute the main parts of the tank container.

A plurality of vacuum-resistant reinforcing rings 1, 1a, 1b, and 1c are provided on the outer periphery of the tank a at appropriate intervals.

In addition, frame b has front and rear corner posts 2,
The reinforcement is formed into a rectangular parallelepiped by the upper and lower longitudinal frames 3 and the end frame 4 of the end part, and the outer peripheral edge of a support plate 6 that also serves as vacuum-resistant reinforcing rings 1 and 1c, which will be described later, is welded at appropriate positions in the direction of both ends. A frame 5 is provided.

The reinforcing frame 5 is completely fixed by welding vertically and horizontally between the upper and lower longitudinal frames 3 constituting the frame b.

Next, at least two vacuum-resistant reinforcing rings 1 and 1c located at both ends of the tank a are extended to the reinforcing frame 5 constituting the frame b to form a supporting plate 6, and the outer peripheral ends of the rings are welded to the reinforcing frame 5. be done. In the figure, 7 is a corner fitting, and 8 is a hatch for injecting liquid cargo.

The tank container of the present invention with the above configuration has excellent stability against vertical loads and lateral loads;
Furthermore, when a tank container is loaded onto a freight car and transported by rail, it may receive severe longitudinal impact when the train is connected.In this case, it is recommended to use a structure with improved strength as shown in Figure 3 desirable.

That is, two support plates 6 are provided at both ends, and as a result, stable strength and rigidity can be obtained also in the longitudinal direction.

[Effect of idea]

As mentioned above, according to the present invention, the tank is supported at appropriate positions on both ends of the frame, resulting in extremely high stability.Furthermore, since the support plate is constructed using a vacuum-resistant reinforcing ring, the materials used and the manufacturing By reducing the number of steps, it is possible to reduce weight and cost.

Furthermore, since the support plate is constructed in the shape of a brim around the outer periphery of the tank, it is easy to wrap a heat insulating material, etc., and the support plate can be easily constructed into a heat-retaining container.
