SE509322C2 - Stackable race goods container - Google Patents

Abstract

The container is used for transporting dangerous bulk material by road or rail. It has a rectangular plan form with a foot (10') at each corner and these feet (10') are supported on two parallel beams (10). The lower part of the container is conical and converges towards the outlet which can be closed to form a gas tight joint by a sliding cover (14). When this cover is fully retracted the full cross-section of the outlet is completely free. The top of each container has four projections (18) which can engage holes (20) in the beams (10) of a second container to enable the containers to be stacked one upon another. USE - Transport of dangerous bulk material.

Description

509 322 10 15 20 25 30 35 were prone to mechanical damage during transport handling. To keep the container ready for use, constant repairs were required.

An object of the invention is therefore to provide a stackable baggage container which has as low a maintenance need as possible and is suitable for receiving baggage in quantities of the order of tons.

This object is achieved with a cargo container according to claim 1.

Embodiments of the container are specified in the appended dependent claims.

It was surprising that a completely smooth, frameless bulk cargo container could withstand the mechanical stresses during transport handling much better, a container equipped with stiffeners and a protective frame.

The invention will be described in the following in the form of an exemplary embodiment, with reference to the accompanying drawing.

Fig. 1 schematically shows a side view of a container according to the invention. Fig. 2 schematically shows a longitudinal section, cross section and an end view of the container outlet valve.

The container shown in Fig. 1 is self-supporting by removing all frames and can be gripped and transported from all sides by means of a forklift truck or the like thanks to two pairs of rectangularly arranged fixedly connected beam pairs (10, 10 ') in the form of rectangular hollow sections.

The actual container (6) which serves to receive cargo goods is carried by four feet which are attached to the beams.

A further feature of the bulk goods container according to the invention is that the container only has a filling valve which can be tightly closed by means of a suitable valve (12). drain opening (14). This opening is arranged on the conical end (8) of the container, ie in the middle between the feet so that the cargo can flow out of the container without leaving any residue. The only condition is that the cone angle for containers under the part corresponds to the race angle for a goods to be transported.

The cargo container is chamfered at its four upper corners. Above these chamfers, diagonally directed loops (16) are attached, which again give the outer dimensions of the container its cubic resp. parallelepipedic shape whereby the ears thus do not protrude past the edges and walls of the container.

In these ears, stacking pins (18) are integrated on the upper side for receiving a suspension chain (4) suspension, or some other lifting device. With the aid of these pins and corresponding recesses (20) in the lower pair of beams, cargo container containers can be stacked on top of each other without risk of slipping.

The filling of the bulk cargo container takes place by opening it at the end with a slide, by turning the container 180 ° so that the outlet opening becomes the filling opening. Since the opening is large enough in that, depending on the size of the container, it can have a free width of 150 to 450 mm, the container can also serve to receive fist-sized pieces.

For transport of particularly moisture-sensitive goods, outlet resp. the filling opening is hermetically closed. This can be done by means of closing means of different types. A so-called lifting slide (see Fig. 2) has proved to be particularly suitable due to its simple design, low weight and small space requirements. This lifting slide is constructed so that its closing plate (48) leaves the entire outlet resp. the filling opening, which enables unobstructed filling and emptying.

The slide housing is designed so that in the open position, the entire closing plate fits in the housing and is thus protected from mechanical damage. The closing plate is actuated with a drawbar (22) which is mounted in a bushing (23) included in the slide housing. By turning the drawbar in a clockwise direction, the closing plate is pressurized by one or more cams (26) seated on the drawbar against the seal (28) of the slide flange, whereby an absolutely tight closure is ensured; by an opposite rotational movement the closing plate is loosened and can be moved back and forth. The rotational movement of the drawbar is limited by pins (30) on the slide (32) attached to the drawbar and the stop (31) on the slide housing.

According to a further feature of the invention, the slide housing is gas-tight and only so large that in the open state it can barely and evenly receive the closing plate, whereby in closed condition, the drawbar including the closing lever (34) is below the conical part of the container. This ensures that the closing member cannot be damaged during transport because it is laterally protected by the feet and protected from below by the beams.

Finally, the lifting slide is secured against unintentional opening.

The drawbar (22) carries at the end a round disc (32) provided with a groove (33) which moves with the drawbar.

Only in the fully closed condition and is a nose (36) provided with a nose into this groove and secures the slide 102 20 25 30 35 509 322 against unintentional opening. For opening ends, you only need to lift the bracket, loosen the closing plate by turning it a quarter turn in the counterclockwise direction, pull the slide and thereby open the closure. A further rotation of the drawbar is prevented by pins on the disc and corresponding stops on the slide housing.

When the slide is opened, a further rotation of the cam (26) by a web (38) arranged in the lifting boom of the slide is prevented so that, for example, a locking of the plate is not possible when the container opening is only partially opened.

For transport of particularly dangerous goods, the container can be flushed with dry air or inert gas. For this purpose, there is a gas inlet connection (42) on the conical part of the container container and in the lower area of the conical part there is a gas outlet connection (44) equipped with a valve.

Containers meet special safety requirements when the gas inlet nozzle is located in the conical part, the gas is supplied via a line to the container side opposite the opening and where it flows out, for example via annular or rake-shaped nozzles (46), and is tangentially deducted at the conical part.

Cargo containers of the type described here are approved by the Bundesanstalt für Materialprüfung for transport both with the Bundesbahn and for road transport.

According to the approval certificate from the Bundesanstalt für Materialprüfung, these containers are suitable for the transport of red phosphorus, coal and lignite dust, solid aluminum alcoholates, magnesium in the form of dust, powder, fine chips, or magnesium alloys with more than 80% 509 322 magnesium, aluminum , zinc, zirconium or titanium dust, freshly extinguished charcoal, powdered or silica calcium silicide, chlorates, calcium carbide and other dangerous substances according to GGVE / GGVS in classes 4.1 to 3la.
