Description

FIELD OF THE INVENTION

The present invention relates to a tank container having a tank and a cuboidal framework which receives the tank via end frames, the framework comprising lateral lower side members and envelope runners extending therebetween.

BACKGROUND OF THE INVENTION

Tank containers are generally known which have a framework and a container. These are usually designed and coupled to withstand certain operating loads permanently. In this case, external loads that act on the container corner fittings are absorbed by the framework and the container itself. The load transmission between the frame and the container is usually via a saddle, in which an annular container element - e.g. an extended jacket shot - coupled to the frame. One speaks of a so-called ring tether, which is particularly robust and weight-saving executable when the operating loads attack only on the front frame and in particular in the corner fittings.

There are different operating loads. There are load cases in which the forces in the area between the front sides of the container attack. These are mainly vertical forces acting from below, which occur during transport on road vehicles. A load case in tank containers is that this is supported next to the crosspoints on the corner fittings in so-called intermediate load transfer areas on the main beams of the vehicle.

Another load case concerns the use of tank containers as roll-off containers. When loading and unloading the tank container via a hooklift system, the container rolls over as a rolling profiles or Umschlagkufen trained side members on roles of a special vehicle from. In this case, act on these profiles substantially vertically upward migratory point loads.

For such load cases, a conventional saddle alone may be insufficient. Known solutions are to perform extremely rigid and rigid frame structures, which reduce so much by Aufdoppelungen or reinforcements of the Abrollprofile their deflection that they absorb the forces occurring during winding and unrolling without the use of the capacity of the container. However, such solutions usually require a height of the overall container negatively influencing reinforcement of Umschlagkufen.

Another approach is to couple the tank in the sole area via suitable metallic saddle elements with the profiles in the sole area (cover profiles9 so that they support themselves on the tank and can take on some of the loads migratory point loads can lead to fatigue on the tank itself.

From the EP 0 733 511 A2 is a dump body with arcuate cross section is known, which is provided in the bottom region with a following the trough contour reinforcing shell which extends between two longitudinal frame parts which rest on the side rails of a vehicle. The reinforcing shell serves as an impact protection for in the trough to be transported bricks.

Out USP 1,848,191 is a vehicle body for a cylindrical tank is known in which the fully insulated tank is largely absorbed by two axially extending curved shell elements, which follow the tank outer contour and are connected to each other via the tank contour adapted transverse ribs.

In particular, in isolated tank containers, the known approaches may have particular disadvantages. Thus, the already reduced by the insulating layer thickness usable volume of the container is further limited by stiff and thus high soil profiles, if the soil profiles are to extend completely outside the insulation.

For floor profiles that are connected to the tank, the insulation must be interrupted in the connection areas. This creates additional thermal bridges. This severely impairs the insulating effect and considerably increases the manufacturing effort and the tare weight.

Another approach according to EP 1 382 548 B1 is to provide a folded or curved shell element which extends between the Umschlagkufen and these connects to each other and in particular welded to them. The shell element is part of the insulation and at the same time a supporting frame element, which should influence the bending properties of the Umschlagkufen low. However, this dynamic loads when transferring (loading and unloading) are introduced into the insulation or in the insulating cover and it can be due to deformation of the connecting joints to leaks in the insulating cover or fatigue problems in the zones come in which a between tank and Insulating cover extending insulating material is too deformed, thereby fatigued and possibly loses its insulating properties.

If the insulating material in addition to a support effect between the tank and frame (via the shell element) to deploy, so this support effect can also be relieved by the fatigue of the insulating material and the structural strength can decrease.

The object of the present invention is to provide a tank container with an improved bottom frame structure, in particular to realize a lightweight and production-friendly bottom frame assembly with Umschlagkufen that can accommodate appropriate operating loads without affecting the structural properties of the tank, and without a dynamic load transfer between tank and floor frame takes place.

SUMMARY OF THE INVENTION

The achievement of this object is specified in claim 1. According to a first aspect, the present invention is characterized in that the longitudinal members of the tank container and the Umschlagkufen on the Umschlagkufen traversing cross members are coupled together. Thus, it is possible to first receive a part of the migratory point load occurring during the envelope over the Umschlagkufen and then derive on the cross struts on the longitudinal beams. As a result of the load transfer to the outside, it is not necessary for the turn-up skids to be changed by a profile change in such a way that the overall height is lost. The available space for the tank and the transport volume remain constant and can be maximized.

Further aspects and features of the present invention will become apparent from the dependent claims, the accompanying drawings and the following description of preferred embodiments.

In an embodiment in which the transverse struts are designed as a square profile or square tube profile, particularly lightweight and rigid structures can be realized.

In an embodiment in which the end faces are fastened at the ends of the transverse struts to the inner flanks of the longitudinal struts, the coupling with the longitudinal struts over straight and low-production cuts is possible.

If the hauling runners are designed as unwinding profiles, they can be used as hauling runners for standardized unrolling systems without additional reworking steps.

In one embodiment, in which an end frame assembly is provided at each end of the tank, each having a lower cross member, whose undersides are each coupled to the tops of Umschlagkufen, and the ends of Umschlagkufen are firmly integrated into the frame structure, in particular in a bottom frame structure , and contribute to stabilization.

In an embodiment in which an insulation and an insulating cover is provided, and Umschlagkufen and cross struts are arranged to each other such that between a sole line of the insulating cover and a top of the transverse struts or the Umschlagkufen a distance ( D ), a deflection-related deflection of the envelope skids and the soil structure can be tolerated without there being any contact between cross struts or cover skids.

The same applies to an embodiment in which a tank is designed without insulation and the distance ( D ) is then formed between a sole line of the tank and the top of the transverse struts or the Umschlagkufen.

This makes it possible to ensure that no loads during the handling (loading and unloading of a hooklift vehicle) affect the insulation or the tank. It can therefore be avoided reinforcing elements or support elements.

In an embodiment in which a Umschlagöse is provided and an end face at the end of a jacket protection is arranged in a plane, and a tank facing end face of a lower cross member extends in this plane, and a side facing away from the tank end face of an upper cross member also in this plane runs, can create a connection between the back of the lower cross member and the front side of the upper cross member. And with a in the connection level (end face of the jacket protection) lying connection plate. At the same time, the upper transverse spar is set back behind the lower transverse spar (in the tank direction), so that an additional space can be formed for a hook lift system or another handling arrangement, and the two transverse bars can nevertheless be coupled to one another in the connection plane of the tank.

In one embodiment, support profiles are provided between which a Umschlagöse is arranged and arranged between the support profiles a flat closure plate which in the Plane is arranged so that between the support profiles and closure plate, a space for receiving a hook lift arrangement is arranged.

In another arrangement, the closure plate is designed such that it extends with an upper region in the tank connection plane and with a lower region in a connection plane offset from this plane in the direction of the tank end, so that an enlarged free space is formed in the upper region of the Umschlagöse. The closure plate is designed cranked.

There are embodiments in which a folding railing arrangement is provided, which can be raised and / or unlocked via an operating arrangement which can be operated by a ladder. This ensures that the folding railing can be actuated from a safe position on the ladder and that the tank only has to be climbed when the folding railing is upright.

The operating instructions, which can serve at the same time for erecting and unlocking the folding railing, it is possible with a simple intuitive control device to perform the functions of the folding railing.

There are embodiments in which the folding railing is provided with additional additional extendable or foldable elements, which additionally cover a partially covered by the folding railing area of a catwalk arrangement or a control platform.

There are even versions in which the upper tank container can be hedged completely with folding and / or folding or Einsteckgeländerelementen.

Embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which:

• 1 a perspective view of an embodiment of a tank container according to the invention;
• 2 a perspective view obliquely from below the in 1 illustrated tank container;
• 3 a perspective longitudinal section of the in 1 and 2 illustrated tank container and
• 4 a section of a railing arrangement.

The tank container 1 includes a box-shaped tank 2 , the front each with two end frames 3 and 4 connected is. The connection takes place via the end edges at the ends of the jacket shot 5 ( 3 ) with the front frame 3 and 4 ,

Here is the front frame 4 designed as an intermediate frame and defined together with another Endstirnrahmen 6 a recording area 7 , which is intended to accommodate aggregates such as pumps, water treatment plants, energy supply, spare parts, etc. The Tank 2 is shorter than the tank container 1 ,

All forehead frames 3 . 4 and 6 include corner posts 8th , Diagonal struts 9 and optionally additional so-called "luggage plates" 10 and lower crossbars 11 , as well as upper crossbars 12 , which also accommodate the tank 2 can serve. The outer front frame 3 and 6 each have 4 corner fittings 13 on, for transporting and handling the tank container 1 serve. Two upper longitudinal spars 14 connect the upper corner fittings 13 and two lower longitudinal spars 15 run between the corner columns 8th the front frame 3 and 6 , directly above the corner fittings 13 with which they have node elements 16 are connected for better introduction of force.

The front relative to the direction of travel front frame 3 includes two internal vertical supports 17 between which an envelope strap 18 is arranged, which is received by a belonging to a hook lift hook to the tank container 1 to recharge or unload from an appropriately equipped transhipment vehicle.

Between the vertical supports 17 runs a cranked partition plate 19 , which is the space between the vertical supports 17 , the upper cross member 12 and the lower crossbar 11 closes. Here is the upper cross member 12 correspondingly unlatched in a middle section and the partition plate 19 is in alignment with the front face 20 connected to the notch. In this case, the front end surface runs 20 in the same plane as the tank-facing face 21 of the lower crossbar 11 , In this way, the upper part 19a of the bulkhead 19 run in the tank connection level and at the same time for coupling with the tank 2 serve, and enlarge the available space in the area of the envelope. In contrast, the under part 19b of the bulkhead 19 on the top of the lower crossbar 11 welded. This creates a robust receiving and guiding space between the vertical supports 17 which can take on the one hand, the larger hook and on the other hand, the slimmer hook arm of the hook lift system. In a non-illustrated embodiment, the bulkhead plate can also be performed unrestricted as a flat component and also in the lower area for coupling with the tank 2 , or with the front end of the jacket shot 5 serve.

Continue to run at the bottom of the tank container 1 as envelope skids 22 trained side members. These run in the longitudinal direction parallel to the lower longitudinal beams 15 and between the front frames 3 and 6 and are each also with a lower cross member 11 of the front frame 4 connected. The distance of the turnover skids 22 to each other and their profile are chosen so that they are compatible with a hook lift system. In the embodiment, the corresponding dimensions are selected so that they fit, for example, to a hook lift system according to DIN 30722. In transport, the two Umschlagkufen lie 22 on corresponding chassis carriers of a vehicle.

When unloading the tank container 1 from the vehicle, the hook lifts the container over the hanger 18 and pushes him by means of the hook lift over transport rollers on the rear of the vehicle out to the rear end frame 6 touched the ground. Until putting on the rear end frame 6 on the ground are relatively high point loads on the transport rollers (arrows P ) introduced into the Umschlagkufen. The point loads P move in accordance with the feed movement of the tank container 1 along the envelope skids 22 longitudinal.

The vehicle then drives under the tank container hanging on the hook 1 out until the front end frame 3 located behind the rear of the vehicle and there is also deposited by the hook lift on the ground. When unrolling the tank container 1 the turnover skids are moving 22 on the transport rollers, which then dependent on the position of the container on the vehicle vertical force component on the Umschlagkufen 22 muster.

The envelope skids 22 are subjected to bending during loading and unloading. This is the top of the Umschlagkufen 22 stressed with a tensile and the underside with a compressive stress. The illustrated turnover skids have a double T-like profile; other suitable profiles for receiving such loads are not shown T, C, U or rectangular tube profiles.

To reduce the bending load and the deflection of the Umschlagkufen 22 These are in the area of the tank 2 over cross struts 23 with the lower longitudinal bars 15 coupled. The cross struts 23 thereby run through corresponding recesses 24 at the top of the envelope skids 22 , enforce these and end with their faces on the inner edges 25 the lower longitudinal bars 15 , The tops of the cross struts 23 The ends are flush with the tops of the cover skids 22 , This is the turn-up skids 22 between the two end frames 3 and 4 such with the lower longitudinal bars 15 connected and supported on these, that the loads occurring there P in this area not just about the handling skids 22 and the lower crossbars 11 , but in addition over the cross struts 23 and the lower longitudinal spars 15 can be included. This will cause the deflection of the envelope skids 22 in the tank area so greatly reduced that the sole area of the tank 2 is not touched by this soil structure.

The Tank 1 is over the front frame 3 . 4 so taken up that the sole line of the insulating cover 26 at a distance D to the (tank facing) top of the cross braces 23 runs. By the design of the lower longitudinal beams 15 , the crossbars 23 , the turnover skids 22 and the lower crossbars 11 formed soil structure may be the distance D be chosen so minimal, just so that the deflection of Umschlagkufen 22 during loading and unloading of the tank container 1 less than the distance D , This will prevent the tank container 1 or the insulating cover 26 of the tank 2 is touched in the ground area during loading and unloading.

This allows the tank 2 be carried out even with the lowest possible wall thickness, which is determined only by any internal pressure load or other factors (specific weight of cargo, dangerous goods regulations, etc.), but so completely independent of the vertical loads (point loads P ) when using the tank container 1 can be. In an uninsulated tank container 1 stands the distance D between the top of the soil structure and the sole line of the tank 2 to disposal.

The tank container is equipped with an insulating cover 26 provided and between the insulating cover 26 and the jacket shot 5 is an insulation 28 intended. The insulating cover 26 is with the help of straps 29 around the jacket shot 5 fixed around. At the ends is the insulation between the tank bottoms 30 and the front frame 3 and 4 provided, which are closed by covers.

In the area of the recording area 7 are cover panels towards the tank 31 provided on the back to the ground 30 define the space for the insulation and on the outside of the receiving area 7 close and protect. The cover panels 31 are made of a sandwich material in which a stabilizing, insulating layer is arranged between two metal layers (foam structure, honeycomb structure, etc.). Due to the light floor structure and the lightweight cover panels 31 can be a tare weight of the illustrated 20 'tank container of about 3,000 kg realize.

4 points to the top of the tank container 1 arranged runway area 32, which can be secured with a so-called. "folding railing" 33. The folding railing 33 is with an operating handle 35 provided by a server on the ladder 34 standing to use and is erectile. About the operating handle 35 is at the same time a release mechanism of the folding railing 33 actuated. At one end of the folding railing 33 is optionally an extendable and fixable extension 36 provided so that the work area completely along one longitudinal side of the tank container 1 is to be secured. Optionally, further railing elements may be provided.

In addition to the illustrated box-shaped cross-section of the tank 2 also have an oval, cylindrical or other suitable cross section. The Tank 2 can also work without the intermediate frame 4 between the outer end frames 3 and 6 extend, if provided for the additional aggregate receiving area 7 should not be required. The invention is also for tank containers 1 which are not to be handled by roll-off systems but in which the bottom frame assembly is used in standard load transfer zones (intermediate load transfer areas) ISO 14963 ) local vertical loads in the area of the side members 22 to record. In this case, the Umschlagkufen can also be used as normal side members 22 be executed without the required Umschlagkufenprofilierung.

The invention relates to a tank container ( 1 ) with a tank ( 2 ) and a cuboid framework that holds the tank ( 2 ) over front frame ( 3 . 4 ), wherein the framework lateral lower Längshole ( 15 ) and intermediate runners ( 22 ), characterized in that the longitudinal beams ( 15 ) and the envelope skids ( 22 ) over the envelope skids ( 22 ) passing cross struts ( 23 ) are coupled together.
