Definitions
- a pressure-resistant tank according to the preamble of claim 1 is out DE-C-3 606 247 known.
- Double-shell design Containers are connected to two or more parallel pipe shells and closed at their ends with bottom shells, the transition areas between bottom and pipe shells of arched gusset elements be formed.
- a tank known from DE-A-3 125 963 is a thick-walled container designed for LPG as fuel for vehicles.
- the pipe shell elements in this tank consist of a fully cylindrical design Shell and a cylindrical partial shell, the partition in question formed by the part of the solid cylinder lying inside the container becomes. Also flattening this part into a train wall for a symmetrical Pressure and stress distribution within the container is provided.
- the object of the present invention is, in particular in known large-volume double-shell containers for use as Tank containers, the tension problems in the transition area between Bottom and jacket shells and the inclusion of the inside pressure resulting tensile forces between the upper and lower longitudinal beads suitable tie rods and the interaction of such a tie rod with to solve any existing flat train wall.
- Another advantage of the present invention is one Low center of gravity container for high wheel, off-road To enable vehicles that are also partially filled longitudinally and reduced across the direction of travel.
- the inventive solution to this problem is in the character part of claim 1 specified.
- the intended cylindrical domed Gusset element can be made much thinner than at a tank of the same pressure resistance without rib elements.
- the membrane stresses caused by the internal pressure in the domed tank skin lead into the beads in which the domed shell elements converge to forces perpendicular to the tank plane defined by the longitudinal axes of the jacket shells to press. According to the invention, these forces are penetrated by the tank ribs running in the direction of the force.
- the rib-shaped Design according to claim 1 offers the advantage that the ribs between the converging sheets can be arranged that particularly simple fillet weld connections are possible. Furthermore offers the flat rib profile very great design freedom to either maximum Surge inhibition or a tension-optimal course To achieve claim 4.
- Form the rib elements according to the invention So a single component, which at the same time the compressive strength of the entire container guaranteed, for a favorable constant voltage curve ensures and as a damping element the surge effect in longitudinal and Cross direction inhibits.
- a particularly advantageous embodiment of the rib elements according to Claim 3 allows to reduce the welding effort and the number the weld seams.
- the rib elements also connected with a vertical profile be necessary as an additional tie rod when high tensile forces occur can be.
- This profile can for example as in claim 6 and 7 indicated a hollow profile, preferably with a circular cross section his.
- Such a profile additionally allows a further reduction weld accumulations, particularly in the area where the The seams of the longitudinal and diagonal beads meet.
- a welding of the elements ribbed sheet, profile and tension wall according to claim 13 gives a further stabilization of the entire structure.
- the embodiment according to claim 14 is special in terms of production technology Cheap.
- the embodiment according to claim 15 makes the tank against manufacturing and Operating voltages particularly insensitive.
- the tank according to FIGS. 1 and 2 consists of two partially cylindrical jacket shells 1 , which are connected to one another via a traction wall 4 which runs in the longitudinal direction parallel to the tank axis 20 and completely penetrates the tank.
- the two shells 1 form two recesses lying within the overall profile of the container, which run as bead-like channels running parallel to the axis 20 on the top and bottom of the tank.
- the end walls of the two ends form two floors 2 , which are each composed of three shell elements 3 .
- a gusset element 5 which is also cylindrically curved and has a tip in the bead, and which then extends obliquely outwards to the point of contact of the shells 1 with the bottoms 2 .
- all outer shell elements 1 , 3 and 5 of the tank have the same radius of curvature.
- Crescent-shaped rib elements 10 are inserted between the gusset element 5 and the shells 1 , which penetrate the container, form an angle of 45 ° with the axis 20 , and are at an angle of 90 ° to one another. These rib elements are connected to the pulling wall 4 by means of a tubular profile element 11 which completely penetrates the tank along a perpendicular axis 21 .
- FIG. 7 shows an embodiment as a bevelled cylindrical claw. Further embodiments can consist of a solid cylinder, a tube, a Doppler plate or a curved bottom element closed to the interior of the tank.
- Figure 3 shows the connection of the shells 1 to the draw wall 4 with fillet welds.
- a further alternative, not shown, consists in welding the tension wall 4 only inside between the upper and lower bead edges running in the longitudinal direction of the tank.
- FIG. 4a shows a variant in which the rib elements 10 are either produced in one piece and symmetrically to the draw wall 4 from a sheet metal blank by folding and are then welded to the draw wall 4 along the perpendicular axis 21 .
- FIG. 4b shows an embodiment in which one wing 10a is folded onto the tension wall 4 and the other wing 10 is welded to it along the edge of the perpendicular axis 21 .
- This embodiment assumes that the tension wall 4 and the wings of the rib elements 10a and 10 have the same wall thickness.
- FIG. 5 shows in detail the connection of the tension wall 4 and the rib elements 10 to a hollow profile element 11 with a circular cross section, the longitudinal axis of which coincides with the perpendicular axis 21 .
- This embodiment shows that while the welds are distributed on the circumference of the pipe and which is also incident on the tube tip ends of the shells 1 and the gusset element 5 are cut at the circumference of the pipe, there to be welded, and do not converge at a point.
- such a hollow profile element 11 represents a connection between the upper and lower corrugation space of the tank.
- the connection between the upper and lower bead cavity remains open.
- the communicating connections also allow the space between the inner and outer tanks to be completely filled with a fluid.
- FIG. 6 shows a possible massive design of the profile element 11 .
- the connecting seams between the tension wall 4 and the wings of the rib elements 10 are spatially separated.
- an angle profile element can also be used, the tension wall 4 then being welded to the edge of the profile at which the two legs converge.
- Leave the versions shown on a double-shell tank are transferred analogously to tanks, for example three or more partially cylindrical Have shell elements whose parallel longitudinal axes in one level.
