Description

[Detailed description of the invention] The present invention relates to a mounting device for a light metal tank in a tank lorry, which allows the light metal tank to be mounted to the subframe extremely easily and reduces the weight of the vehicle. This is what I did.

Recently, in tank trucks, tanks made of light metals, especially aluminum, have been increasingly used, as they have superior properties compared to tanks made of steel plates.

As a mounting device for this aluminum tank or the like onto a steel chassis frame, for example, a weldable aluminum sub-frame is welded to the tank over approximately the entire length of the bottom surface of the aluminum tank in the longitudinal direction. Conventionally, this subframe was fixed to the opposing chassis frame using U bolts or the like.

However, with this conventional device, large distortions occur in the sub-frame due to welding, and since it is fixed to the chassis frame (・), it has been pointed out that there is a problem in maintaining the strength of the tank (・Ta.

Therefore, as a mounting device, for example, a required number of aluminum receiving members are welded to the lower part of an aluminum tank, and correspondingly, bolsters provided on a steel plate subframe fixed on the chassis frame are mounted. Fixed ones were also used conventionally.

However, conventional devices using this bolster have a complicated structure and are complicated to install.
Furthermore, problems have been pointed out, such as an increase in vehicle weight and a corresponding decrease in payload.

Furthermore, with these conventional mounting devices, when it is desired to reuse the tank by replacing it with another chassis frame due to aging of the chassis frame, the width of the chassis frame varies slightly depending on the model (・It was also pointed out that the economical problem was that it would be difficult to replace and install the vehicle onto a different type of chassis frame.

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a light metal tank in a tank lorry, and the required symmetrical positions of the lower surface of the tank 1 in the longitudinal direction, for example, the symmetrical positions of the lower surface of the front and rear ends of the tank 10, and the partition wall 1a of the tank 1. The upper ends of light metal box-shaped support legs 2, each of which has a mounting flat plate 2a integrally provided at its lower end, are welded to symmetrical positions on the lower surface thereof.

Reference numeral 3 denotes a steel chassis frame, and a light metal sub-frame 4 is superimposed and fixed in the longitudinal direction on this chassis frame 3 by any means.

On the upper surface of this subframe 4, light metal mounting seats 5 are provided at positions corresponding to the mounting flat plates 2a of each of the support legs 2.
are each welded.

Then, hang the tank 1 with a crane, and install each mounting seat 5.
The flat mounting plate 2a is brought into contact with each support leg 2 above, and the flat mounting plate 2a and the mounting seat 5 are fixed with bolts 6. In view of the fact that the connection and fixation is done by overlapping the plates, as is clear from the illustrated example, we will also take measures to deal with it even when the tank 1 is later mounted on another type of chassis frame whose width is slightly different. It is also natural that the process is smooth.

In the above embodiment, the subframe 4 and the mounting seat 5 are made of light metal to further reduce the weight of the vehicle, but the present invention is not limited to this, and the subframe 4 and the mounting seat 5 are The material may be ordinary metal or other materials.

As described above, according to the present invention, a light metal tank can be attached to the subframe extremely easily.

Moreover, it is well known that the support legs occupy a large amount of weight in the mounting device and in the vehicle body in terms of volume, etc., but since the support legs are box-shaped and made of light metal, the weight of the vehicle can be reduced. Therefore, kerosene (specific gravity 0
For example, it is now possible to load 14Kt of light oil (specific gravity 0085) in a tank that can load 14KL of 08).

Furthermore, since there is no response blocking member in the longitudinal space between the tank and the chassis frame, piping work is extremely easy.

As described above, it is obvious that with the mounting device for a light metal tank in a tank lorry according to the present invention, the tank load can be distributed almost evenly on the chassis frame using the plurality of box-shaped support legs. Moreover, since the support legs are box-shaped, they have excellent strength, and combined with the fact that the chassis frame is reinforced by a subframe, the following effects are achieved without sacrificing strength.

In other words, since the tank made of light metal such as aluminum and the sub-frame made of light metal such as aluminum are not directly welded, it is clear that there will be no large welding distortion, and from this point of view the strength is improved. In addition, it has a simple structure without using bolsters, etc., and the installation work is easy because the mounting plate and the mounting seat are fixed in contact with each other.As mentioned above, the piping work is also easy. It is also excellent in terms of efficiency, and due to its simple configuration and the use of box-shaped support legs as mentioned above, it is also excellent in terms of loading, such as reducing the vehicle weight and increasing the loading weight. Furthermore, the problems that existed in conventional devices of this type have been completely eliminated, and the effects that have been achieved are remarkable.
