Definitions

  • the invention relates to a pallet container for storing and transporting, in particular, flammable or highly flammable liquid filling goods with a thin-walled rigid inner container made of thermoplastic material for holding the liquid filling material, with a tubular grid frame which tightly encloses the plastic inner container as a supporting jacket and consists of horizontal and vertical tubular rods welded to one another and with a floor pallet on which the plastic container rests and with which the pipe grid frame is firmly connected, the plastic inner container possibly being enclosed within the pipe grid frame by a fire protection insulating mat, and the floor pallet as a composite pallet with an upper support plate made of sheet steel , directly below the support plate arranged support pipe linkage made of parallel and diagonally running pipes, corner and middle feet and a bottom pipe link or base running underneath the corner and middle feet is ring tube is formed from steel tube.
  • Such a generic pallet container with a diamond-shaped support frame is in development as an in-house development WO 2014/044372 A1 (with electrical derivation) as well as in the publication WO 2014/044375 A1 (with clamping of the sheet steel plate) described in detail. Both publications are referred to with regard to the constructive pallet structure.
  • the bottom pallet is designed as a steel pallet with an upper steel sheet trough and a tubular steel support frame arranged underneath and is equipped with a cross member directly below it to support the upper sheet trough.
  • the two outer ends of the crossbar are formed as one-piece molded center feet, which are welded to the longitudinal tubes of the lower frame, and which are positioned on the two long sides of the floor pallet.
  • the crossbar is between the middle feet designed as a profiled stiffening plate and provided with longitudinal ribs and outer flanges for this purpose.
  • a narrow, flat sheet metal strip has virtually no bending stiffness;
  • the sheet metal strip only obtains this bending stiffness through the molded-in longitudinal ribs and folded flange edges.
  • these indentations must have a certain height / depth of at least 10-30 mm in order to achieve sufficient flexural rigidity.
  • this then reduces the entry height for the forks of a forklift vehicle, because filled pallet containers with a weight of approx. 1000 kg or more can only be handled with forklift vehicles.
  • pallet containers are always picked up from the front, so that the crossbar - as the name suggests - always stands in the way of the retracting fork tines.
  • the one-piece molded middle feet are only provided with a simple structural shape with thin side flanks, so that they could not withstand the loads caused by the constantly striking fork tines and soon showed corresponding deformations. Therefore, in the publication EP 2 520 504 (Prot ) proposed an improved midfoot for a steel pallet, which should eliminate the disadvantages described above and have a higher stability against laterally acting forces of fork tines.
  • the production and shaping in the deep-drawing process from a one-piece piece of sheet steel is complex and cost-intensive. A crossbar is still required.
  • the rear metatarsus on the opposite side of the tapping nozzle is insufficiently supported by two parallel tubes and the thin-walled floor pan and is therefore particularly at risk of tilting and bending when the forklift is being set down.
  • This well-known pallet container with improved fire protection equipment is designed to meet the fire protection guidelines according to the US standard NFPA-30 for the storage of flammable and highly flammable liquids, which is monitored by the Underwriters Laboratories (UL) will, and should protect the inner bladder in the event of fire for at least 20 minutes with the help of a sprinkler system against damage or against leakage of the liquid filling material.
  • UL Underwriters Laboratories
  • At least one metatarsus of the floor pallet consists of two separate sheet steel parts, namely an outer metatarsal part and an inner metatarsal part, which are specially shaped in the stamping and bending process in such a way that they are installed between the upper support tubes and the circumferential floor-pipe linkage are fixed, with the two metatarsals mated together in a simple plug-in assembly.
  • the metatarsal parts can be designed in three different ways, namely firstly completely free of a directly directed attachment, secondly locked against each other and otherwise free of any direct fixed connection (screwing, welding) and thirdly firmly connected to one another. This enables inexpensive production of the individual parts with simplified assembly of the components in the floor pallet system.
  • the outer metatarsal part with a central smooth outer wall part with laterally connected, obliquely bent back wall parts, with a narrow top flange strip connected at the top, bent backwards at right angles and with a bottom connected to it, also connected bottom flange strip bent backwards at right angles has a box-shaped structure that is open at the rear.
  • the outer midfoot part is only made in a simple stamping and bending process from an inexpensive sheet steel part with a wall thickness of approx. 2 mm and, as a further step, only requires the introduction of drill holes or threaded holes. A complex welding of individual parts is not necessary, the component is immediately ready for use or ready for installation.
  • the inexpensive quick assembly is made possible in particular by the fact that the inner midfoot part in the installed final state, as it were, as an inside rear wall for closing the box-shaped structure of the outer midfoot part, which is open at the rear, via a coordinated sheet metal nose / slot form-fit connection in the rearwardly bent bottom flange strips of the outer midfoot part inserted and is otherwise free of any direct, fixed connection (screw connection, welding) to another component of the floor pallet.
  • the upper narrow head flange strip of the outer metatarsal part is connected upwards from below with an angle rail or the lowest horizontally circumferential base ring of the tubular grille frame and the lower floor flange strip of the outer one Metatarsal part between two diagonally running, downward bent upper support tubes and the surrounding floor tube frame is integrated.
  • Another cost advantage can be achieved if a less complex configuration of the metatarsus, in which the inner metatarsal part is dispensed with, is attached to a position that is typically not so heavily loaded, ie in a position that permits this from the standpoint of stability and construction.
  • the inner metatarsal in the final installed state forms a firm support with downward support for the two parallel steel tubes, the ends of the two parallel steel tubes being clamped under the head flange strips of the outer metatarsal part and are thereby fixed without further attachment.
  • This constructive measure allows - like the following - a simple assembly of the reduced number of individual parts, the inner metatarsal in the final state as the inside rear wall of the box-shaped structure is bent twice on both outer sides and these double-bent wall parts form a kind of wall chamber, in which opens into a right-angled bend of the diagonally running steel pipes, which is screwed on the end face to the bottom-running floor tube frame.
  • the stability of the midfoot construction is further increased by the fact that the outer midfoot part is bent twice on both outer sides of the box-shaped structure in the installed final state, and these angled wall parts also form a kind of wall chamber, into each of which a right-angled arch piece of the diagonally running support frame Steel pipes empties, which is screwed to the front through a through hole made in the rear-bent bottom flange strip with the bottom-running floor tube linkage.
  • the features of the present invention shown above make it possible to design a special pallet container with a flame protection device (“UL-IBC”) with a composite pallet with heat-sensitive plastic pallet feet in such a way that it is at least for a period of about 25 minutes withstands the effects of external flames.
  • UL-IBC flame protection device
  • the measures according to the invention ensure that when exposed to heat from fire and the softening of the thermoplastic material begins
  • the corner feet of the floor pallet prevent the pallet feet from buckling on one side and subsequent overturning of two filled UL-IBCs stacked on top of one another.
  • Reference number 10 denotes a pallet container according to the invention (UL-IBC) with a filling volume of 1000 l, with a (not visible) thin-walled rigid inner container made of thermoplastic material for the storage and transport of particularly dangerous flammable liquids, with a plastic Inner container as a support jacket tightly enclosing tubular grid frame 12 and with a bottom pallet 14 on which the plastic container rests and with which the outer support jacket is firmly connected.
  • the tubular lattice frame 12 of the pallet container 10 consists of horizontal and vertical tubular bars 16, 18 welded to one another in order to obtain a closed outer container the circumferential horizontal tubular rods 16 are firmly and permanently connected to each other.
  • the base pallet 14 is designed as a so-called composite pallet (sheet steel plate on a tubular steel frame with plastic feet), with an upper support plate 20 made of sheet steel for supporting the inner plastic container, with corner feet 22 and made from thermoplastic material by injection molding Steel feet made of steel sheet 24. Below the corner and middle feet 22, 24, a horizontally circumferential floor tube linkage 26 made of steel tubing is attached.

  • a special shell-shaped metatarsus made of plastic is arranged on the front side on a narrow side of the base pallet 14. This bowl-shaped metatarsus sits there directly below the tap of the plastic inner container.
  • corner feet 22 are also made of plastic, while the two side center feet 24 and a rear center foot 30 are now made of stable sheet steel. Below the corner and middle feet 22, 24, 30 runs the horizontally circumferential floor tube rod 26 made of steel tubing.
  • FIG 3 is the composite palette acc. Fig. 2 shown in perspective view, now without the upper steel sheet support plate 20. This should illustrate the constructive substructure of the composite palette.
  • the upper support tube linkage sitting directly below the support plate 20 can now be seen.
  • the upper support tube linkage consists of two straight steel tubes 32 running parallel to one another and close to one another between the two lateral center feet 24 and four steel tubes 34 running diagonally between all four center feet 24, 30, with the steel sheet support plate 20 and two on the long sides of the composite Pallet-extending angle rails 36 form the upper supporting frame of the floor pallet 14.
  • the corner and middle feet form the distance to the support floor and create the necessary space for the engagement of the forks of a forklift vehicle.
  • the floor tube linkage 26 is also referred to as the base ring tube and has a circular cross section with a diameter of 20 mm in the area of the corner and center feet.
  • the base ring tube is flattened between the corner and middle feet, where the forks of the forklift truck are to engage - from the front, from the rear or from the two opposite long sides of the floor pallet and has only one for improved retraction of the forks Height of approx. 15 mm (cf.

  • FIG 4 the special structural shape of a lateral metatarsus 24 is shown in a perspective view.
  • the metatarsus 24 consists of two separate sheet steel parts, namely an outer metatarsal part 38 and an inner metatarsal part 40, which are specially shaped in the simple stamping and bending process in such a way that in the unassembled state they only engage in a form-fitting manner when loosely plugged together. and are free of a directly directed attachment (plug-in assembly).

  • a short longitudinal slot 64 is also punched into the inner edge of the rear half 56 of the bottom flange strip 50. These longitudinal slots 64 are used for the positive connection for the engaging sheet metal lugs of the inner metatarsal part 40.
  • the cross members designed as parallel tubes are merely inserted into the center feet and clamped between the outer part and the inner part, the parallel tubes being easy to manufacture and at assembly are just as easy to assemble.
  • the simple final assembly also results from the fact that the center feet are essentially screwed to their underbody between the right-angled bends of the diagonal support tubes of the upper support tube linkage and the base tube linkage encircling the base (cf. Fig. 8 ).

  • the side wall parts 44 and / or the flange strips are therefore not welded to one another any more than the inner to the outer metatarsal part.
  • the two flat main wall parts 68 of the inner metatarsal part are each provided with a semicircular groove 76 on their upper edge (as a support for the parallel steel tubes 32).
  • the upper narrow head flange strip 48 has two through holes 62 and a central prestole 78 in the form of a specially designed threaded hole for fixing the tubular lattice frame.
  • the two through holes 62 serve to fix the angle rail 36 and could also be designed as a Prestole threaded hole.
  • the fully assembled state of a lateral metatarsus 24 within the floor pallet 14 is shown in a corresponding perspective view in Figure 6 shown, the steel sheet support plate 20 and the tubular grid frame 12 have been omitted for clarity.
  • the angle rail 36 is now attached to the upper narrow head flange strip 48.
  • the angle rail 36 has an upwardly open U-profile and is used on the two long sides of the floor pallet 14 primarily for clamping and fixing the double-angled edges of the steel sheet support plate 20 which are on the pallet subframe is spanned (cf. Fig. 3 ).
  • the angle rail 36 is firmly riveted through the two outer through holes 62 in the head flange strip 48, or if the through holes 62 are also designed as Prestole threaded holes 78, screwed directly and clamps the angled edges of the steel sheet support plate 20 among themselves.
  • the upwardly open angle rail 36 serves to receive and fix the lower, horizontally rotating tubular rod 16 of the tubular grid frame 12.
  • the central Prestole 78 is provided as a specially designed threaded hole.
  • the lower horizontally circumferential tubular rod 16 of the tubular grid frame 12 is thereby screwed to the head flange strip 48 of the outer metatarsal part 38 by means of a stable threaded screw through the angle rail 36 and the angled edge of the steel sheet support plate 20.
  • the rear half 56 of the base flange strip 50 of the outer metatarsal part 38 which is slightly raised by the step 54, is seated on the base ring tube or base tube rod 26 encircling the base.
  • the diagonal steel tubes 34 of the upper support tube linkage of the floor pallet 14 are bent downward in each of their two end regions by 90 ° to form an arc piece 80.
  • These curved pieces 80 with a length of approx. 90 mm each engage from above into a wall chamber 82 formed from the two smooth main wall parts 68 and the adjoining, reduced in height, twice angled back wall parts 70, and end with their circular end face on the upper side of the slightly raised rear half 56 of the bottom flange strip 50.
  • one of the through holes 62 is provided in the rear half 56 of the bottom flange strip 50.
  • the inner metatarsal 40 is - as described above - by means of two locking lugs (sheet metal lugs) formed on the lower edge of the two planar main wall parts 68 in a form-fitting and immovable manner in two corresponding longitudinal longitudinal slots 64 in the slightly raised rear half 56 of the bottom flange strip 50 of the outer Metatarsal 38 inserted.
  • a corresponding plug-in connection also exists between the open slot 72 in the two shortened support wall parts 70 of the inner metatarsal part 40 and the short sheet metal nose 74 inserted therein at the lower end of the rounded, inwardly bent side wall end pieces 46 of the outer metatarsal part 38.
  • a further direct fixation of the Inner metatarsal part 40 with the outer metatarsal part 38 is not required, but the metatarsal parts can also be locked against one another and otherwise free of any direct, fixed connection (screw connection, welding) or also firmly connected to one another.
  • the metatarsal parts can be locked against one another in that the latching lugs formed on the planar main wall parts 68 are slightly rotated after insertion into the longitudinal slots 64. This uncomplicated locking enables the inexpensive manufacture of the center feet as a pre-assembled component for simplified, cost-optimized final assembly of the pallet container.
  • the inner metatarsal part 40 is further fixed by the two arc pieces 80 of the diagonal steel tubes 34 which engage from above and which open into the wall chamber 82 formed by the support wall parts 70 angled backwards and through the rear half 56 of the Bottom flange strip 50 are screwed through to the base ring tube 26. Furthermore, the inner metatarsal part 40 of the two center feet 24 arranged on the long sides of the floor pallet 14 is fixed by the two parallel tubes 32.
  • the two parallel tubes 32 at its two pipe ends a flattened and slightly bent down, ie slightly flattened end area.
  • the inner metatarsal part 40 is inserted in the final state, as it were, as an inside rear wall for closing the box-shaped structure of the outer metatarsal part 38, which is open at the rear, via a coordinated pin-slot form-fit connection in the rearwardly bent bottom flange strip 50 of the outer metatarsal part 38 and otherwise preferably free of any direct, firm connection (screw connection, welding) to another component of the floor pallet 14.
  • the box-shaped metatarsus 24 viewed from the outside, has a width of approximately 160 mm and a depth (inwards) of approximately 52 mm and a height of approx. 100 mm.
  • the steel sheet used for this has a wall thickness of approx. 2 mm.
  • the corner and middle feet of the floor pallet of a filled pallet container are usually very heavily loaded by the forks of a forklift vehicle.
  • the outer metatarsal part 38 it is in particular the flat side wall parts 44 which are bent backwards and subsequent rounded side wall end pieces 46 which are most stressed by the fork tines.
  • a short sheet metal nose 74 is arranged at the outer end of the rounded, inwardly bent side wall end pieces 46 of the outer metatarsal part 38, which positively in the slot 72 open from below in the front halves of the two shortened support wall parts 70 of the inner metatarsal part 40 engages, a stable support of the claimed wall parts 44, 46 is effected.
  • the outer ends of the inner metatarsal part 40 which form the wall chamber 82, are “wrapped”, so to speak, around the arch 80 of the diagonal steel pipes 34 engaging therein and provide additional support by means of a support thereon via the form-fitting engaging slot / nose connection of the claimed wall parts 44, 46 of the outer metatarsal part 38.
  • FIG. 7 A simplified version of a midfoot is in Figure 7 shown.
  • This simplified metatarsus 30 is located on the narrower back of the pallet container (opposite the outlet fitting - cf. Fig. 3 ) Application, since here no parallel but only two diagonal steel tubes 34 open and are stored. The fact that no parallel steel pipes are provided here means that the inner metatarsal part 40 is also dispensed with or is saved entirely here.
  • the upper narrow head flange strip 48 is connected upwards from below with the C-profile or the lowest horizontally circumferential tubular bar of the tubular grid frame 12 and the lower bottom flange strip 50 of the outer metatarsal part 38 is connected to the two diagonally extending upper support tubes 34 and the circumferential bottom tube linkage 26 connected.
  • the part representation in Figure 8 shows in detail (omitting the steel sheet support plate, the angle rail and the tubular grid frame) the support of the two diagonal tubes 34 via their end-side elbows 80 on the rear half 56 of the lower floor flange strip 50.
  • the elbows 80 are on the end face - as before described - clinched to form a threaded sleeve nut and firmly screwed and fixed into the sleeve nut by means of a countersunk or pan-head screw inserted and countersunk from below through the bottom tube linkage 26 and the bottom bottom flange strip 50.
  • the present solution according to the invention provides the advantage that an additional electrical discharge device of the usually non-conductive plastic feet can be dispensed with.
  • an additional electrical discharge device of the usually non-conductive plastic feet can be dispensed with.
  • a device or measure for discharging electrical charges into the base is mandatory according to the required approval regulation.
  • the center feet made of sheet steel are screwed on the one hand upwards to the outer edge of the upper steel sheet support plate 20, the steel sheet angle rail 36 (and also the tubular grid frame 12) and, on the other hand, to the bottom tubular pipe linkage 26 running around the bottom.
  • the discharge of electrical charges from the stacked container into the ground is guaranteed.
  • the stacked pallet container stands with the outside or front halves 58 of the bottom flange strips 50 of the center feet and corner feet on the uppermost circumferential horizontal tubular bar 16 of the tubular grid frame 12 of the stacked pallet container, with the lower-lying circumferential bottom tube rod 26 of the stacked pallet container below of the rear halves 56 of the bottom flange strip 50 of the middle feet is fastened, from the inside rests against the uppermost circumferential horizontal tubular bar 16 of the tubular grid frame 12 of the stacked pallet container and engages a bit from above in the tubular grid frame 12 of the stacked pallet container and thus slides sideways prevents stacked pallet containers.
  • the metallic contact between the floor-pipe frame and the pipe grid frame enables the safe discharge of electrical charges.
