Description

[Detailed description of the invention] The present invention is a container for use as an exchange container in a land transport aircraft, and has an end frame and corner fittings, a curved vertical wall, and an end part with dimensions and spacing according to the international standard (ISO). This concerns a possible tank container.

Although exchange containers and superstructures for charging goods with fine standard dimensions have been known and common in the cargo handling field for many years, it is still insufficient to transport liquids using exchange tanks. has not been developed. Known transport vehicles have the same connection dimensions, so they can be used not only for exchange containers but also for Series 10.
(6096mm = 20 feet), although the total weight of an ISO tank container of this dimension is more than 20000Kg (20 tons) and therefore the European permissible replacement container (13000Kg =
(13 tons) significantly exceeds the maximum weight.
Furthermore, ISO tank containers, unlike exchange containers, are generally not equipped with centering devices at their bases, and the center of gravity of known tank containers is unfavorably located.

This situation has not currently been improved in tank containers for combined sea and land transport aircraft for various reasons. However, for inland transport it has been suggested that tank containers of reduced height and oval or square cross-sections are preferred as stackable liquid tanks for replacement superstructures. These containers are up to
It has a small height of 1500 mm and when empty it can be placed above the vehicle without exceeding the maximum permissible height for road trucks.
Can be stacked to double the height. Besides the low height, the advantage is that the center of gravity is low when filled with liquid. Oval or square tank cross sections allow efficient use of space, but are not well suited for pressure resistance, which is often necessary for safety.

Pressure-resistant tank containers of small height are also known, the vertical walls of which consist of mutually transverse longitudinally parallel cylindrical cases (for example,
(See Publication No. 99708). However, when applying such prior art construction to a tank container having end frames and corner fittings with standardized spacing and dimensions such as ISO, the length of the tank container is
For example, the ISO container standard length is series 10, or 6096 mm. On the other hand, most vehicles transporting exchange containers have a length of about 7 m.

Corner fittings of ISO series 10 containers are thus spaced longitudinally of the tank at a distance significantly less than the useful length of the vehicle used to transport the exchange container, and therefore the above If a tank container of prior art construction were to be transported on such a typical vehicle, a large portion of the vehicle's length would remain unused.

One object of the invention is thus to provide a vehicle with additional capacity beyond the length specified by the corner fitting, even when having corner fittings at standardized spacings such as the ISO standard. An object of the present invention is to provide a tank container for land transportation that can effectively utilize the entire length of the container.

Another object of the present invention is to provide a tank container for land transportation that can add capacity and allow tank containers to be stacked on top of each other so that the entire length of the vehicle can be effectively utilized. be.

According to the tank container of the invention, at least one end of the tank container is formed as a projecting part, which is seated on the outer end surface of the frame and extends in the longitudinal direction of the tank beyond the corner fitting. In this way, the entire loading area of the transport vehicle can be utilized with a low center of gravity without exceeding the permissible total weight of the exchange container. It should be noted that the end frame may be made from hot-rolled T-section structural steel or extruded aluminum, in which case the inwardly extending web of the T-section may be surrounded by the material of the tank. made from this material. This design is possible because of the small stacking height and is preferred because it is more economical than hitherto used end frames of rectangular cross-section tubes made of alloy steel.

Some embodiments of the invention will be described in detail below with reference to the drawings. 1 and 2 show a tank container, the longitudinal wall 1 of which consists of mutually transverse partial cylindrical cases. These vertical walls are pressure-resistant due to the vertical members 2 and their clamping bars 18. The vertical wall 1 is mounted on a group of 3 bases resistant to distortion, and the ends of the vertical wall 1 are mounted on a frame 4, which is provided with corner fittings 5 for stacking and lifting purposes.

A projecting portion 6 is seated and fixed on the outer end face of the frame 4, and this projecting portion 6 acts as an end wall of the tank container. These projecting parts consist of two halves of a cylindrical pressure vessel 7 with a dish-shaped end plate 8 cut in two longitudinally. Each of these pressure vessel halves extends horizontally across the container axis, i.e. its longitudinal axis extends at right angles to the container longitudinal axis, and is positioned and welded to the outer end face of the frame 4.

If the protruding portion 6, which is a half of the cylindrical pressure tank, is seated and welded to the outer end surface of the frame 4 (the outer surface of the vertical web 14), the upper surface of the frame 4 may be interfered with by the protruding portion 6. Therefore, other containers can be stacked on the corner fixtures 5 of the frame 4.

The diameter of the protrusion mounted in this way need not correspond to the height of the frame, but may be larger or smaller than the height of the frame, depending on the required additional content, in which case the frame end faces are sufficient. Care must be taken to ensure a wide range of Depending on the height position, the protruding part is used to compensate for the air in the gas space above the liquid level or to connect the lower line of the vertical wall 1 of the container or both. For this purpose, only the frame parts 10 or 11 that project into the inside of the tank must be provided with openings 12 or 13 near the lower or upper line.

The protruding parts must be provided symmetrically on both end walls of the container, or they may be provided at only one end or at different heights. For example, when the projecting part of the container is positioned high at the front end and generally slightly higher above the vehicle and lower at the rear end, air compensation is ensured at the front end and complete emptying at the bottom.

The corner fittings of the end frames only need to hold double or triple the dead weight in contrast to ISO containers so the frame is economically made with hot rolled or extruded T-sections 10a ,11
a (Figures 3 and 4). Since only the web of the T-shaped part that projects inside the container comes into contact with the liquid, this web must be made of or coated with a corrosion-resistant material. The T-shaped section 10a according to FIG.
(e.g. alloy steel or aluminium). On the contrary, in the embodiment of FIG.
6 is made of a non-corrosion resistant material, and the central web 17 is made of a corrosion resistant material. The ends of the longitudinal walls 1 are welded to the surface of the central web 17 or the cladding 15, while the dish-shaped end plate 8 (shown in two different dimensions) is welded to the outer surface of the central web.

One example of a manufactured tank container has a width of 2348 mm, a height of 1500 mm and a total length of 7150 mm.
It was hot. The center spacing of the corner fittings had a standardized dimension of 5853 mm and the radius of the overhang was 541 mm. The container had a volume of 17.2 m ³ and was rated at 1.75 bar above atmospheric pressure. The dead weight was 3100Kg and the total weight was 20300Kg.

According to the invention, as mentioned above, the curved end of the tank container consists of a protruding part extending in the longitudinal direction of the tank container beyond the corner fittings, so that the tank container can meet standardized spacings such as ISO. This is economical because the entire length of the vehicle can be used effectively even when corner fittings are provided, and since this protruding part is seated on the outer end surface of the end frame, this protruding part increases the capacity. The addition of a 100mm dot allows tank containers to be stacked without interfering with stacking other containers on the corner fittings of the end frame.
