Abstract
The invention relates to a palette container (10) comprising a thin-walled rigid inner container (12) made of thermoplastic synthetic material for storing and transporting liquid or flowable filling products. The inventive palette container also comprises a grid tube frame (14) which, as a support casing, closely surrounds the plastic container (12), and comprises a base palette (16) on which the plastic container (12) rests and to which the support casing is firmly attached. The grid tube frame (14) consists of vertical and horizontal tubular rods (30, 32) that are welded to one another at points of intersection (36). Several prior art palette containers exhibit substantial shortcomings (grid tube fatigue fracture) when subjected to prolonged dynamic vibrational stress that occurs, for example, during persistent stresses caused by the transport on roads of poor quality. The aim of the invention is to achieve an adapted optimal vibrational elasticity in order to improve the stability of the grid frame while providing a sufficient degree of flexural strength. To this end, the tubular rods (30, 32) have a closed profile (18) with a particular trapezoidal cross-section.
Description
The present invention relates to a kind of palette container, it has and is used to preserve thin-walled endogenous pyrogen with transporting fluid or free-pouring article with the thermoplastic material manufacturing, wherein plastic container are closely surrounded by cage type overcoat and base supporting plate, described cage type overcoat is made up of as supporting shell the pipe bar that intersects, thermoplastic containers is supported on the described base supporting plate, and this base supporting plate is connected securely and supports on the shell.
As for example common known this palette container that has the pipe bar support sleeve of welding in EP 0 734 987 A (Sch).The pipe bar support sleeve of disclosed palette container is made up of the pipe bar of circular profile, these bars the welding point of crossing by high compression.From DE 297 19 830 U1 (vL), know another kind of palette container, but its cross-sectional plane obviously is identical, the impression that does not have any indenture or cause cross-sectional plane to reduce on the whole length of bar with varying cross-section structure pipe bar.Know the another kind of palette container of band cage from DE 196 42 242, wherein cage has open-type facial canal bar.Wherein, laterally outwards flanging face the regional weld together that intersects at the cage bar directly.Because having small torsional stiffness and make, their the sharper outer flanging of thickness and edge, open pro-file cage bar be difficult to carry palette container with hand.In addition, the also known in the prior art various palette containers that have rectangular cross section cage bar.
Cage type is enclosed within outward and can be configured to adhering on the base supporting plate with the lifting plate or be configured to steel pipe frame of plastics or timber manufacturing, and for example screw, carriage, clip or the fastener realization of attachment device by engaging with lower horizontal and the cage bar that circumferentially extends usually.These attachment devices or nail exist, and are riveted on, and are screwed in or are welded on the top board or top outer rim of supporting plate.
For industrial use or when in chemical frbre industry, using palette container, the approval check that they must be by government and satisfy various quality controls.For example, the palette container of filling has the internal pressure test of bearing and from the impact test of specified altitude.Combination-the IBCs of palette container or type described here (IBC=bulk mesophase container) preferably is used for transport liquid.Particularly when the combination of filling-IBCs with truck transport, owing to especially be the transportation impact on the bump course and the motion of transport vehicle, sizable motion of gushing out of liquid container Loaded goods can take place, thereby applied the pressure of continuous variation on inner reservoir wall, this produces radial vibration (dynamically continuous shaking stress) again in the rectangle palette container.According to the structure of cage type overcoat, in the long period transportation process on bad road, formed stress gradually, make cage bar fatigue also rupture.Therefore, this palette container is not suitable for for example exporting to the U.S., perhaps is not suitable for high-mobility, multipurpose, wheeled vehicle.
The shortcoming of embodiment is the round tube profile of level and vertical cage pipe bar among above-mentioned EP 0 734 967 A, particularly in cross-point region, is easy to take place sizable distortion especially in the position of weld, thereby compares with other zone, and section modulus obviously reduces.In addition, pipe bar profile is recessed darker near the weld nugget indenture, thereby has further weakened bar, by welding the material in recessed pipe bar profile zone is become fragile thus.
The palette container that the objective of the invention is to avoid above-mentioned shortcoming and propose to improve transportation intensity, it provides the anti-transportation stress of improvement, the ability of long-term vibration stress with simply constructed device.On the one hand, palette container should be fit to transport the hazardous fluids or the free-pouring Loaded goods of the highest permission level standard; On the other hand, when satisfying the standard traffic requirements, it should be able to be with still less vertical and/or horizontal cage bar structure cage type overcoat and its mechanical stability does not descend.
Technical scheme
According to the present invention, this purpose is by providing band to be realized by the palette container of the cage type overcoat that vertically becomes with the tubular steel pipe of level, wherein the cage bar has the trapezoidal cross-section of closure profile, cross-sectional plane has the long and short sidewall that extends in parallel and two straight sidewalls that incline towards each other and extend, the extension that begins to incline towards each other of the longer sidewall of these two straight sidewalls from parallel side wall, be connected on the shorter side wall, two straight sidewalls that extend that wherein incline towards each other form about 20 ° to 45 °, preferably about 36 ° drift angle.Because the profile sidewall tilts each other slightly, so the trapezoidal closure profile of pipe bar has high bending sections modulus and height reverses section modulus.This particularly compares in 0.8 to 1.0 scope at high wide (H/B) of laddertron profile, realizes in preferably about 0.86 o'clock.By palette container according to the present invention, can realize such cage type overcoat, promptly sustain forseeable standard transportation stress, its structure has altogether only 5 rather than 6 horizontal cage bars, but mechanical load-carrying capacity does not obviously descend.
In one embodiment of the invention, in part, two cage bar intersection regions, the longer parallel side wall of trapezoidal profile cage bar inwardly concaves along the length of about twice cage bar width by this way, promptly two outer longitudinal edges form a convex surface, make each infall of the vertical and horizontally extending cage bar that links together securely after the welding form four points, whereby at each cage bar infall (longer) respect to one another even parallel walls is not in contact with one another after welding yet.
In a preferred embodiment, inwardly concave (=continuous vertical indentation or die mould) than longwell by this way along its whole length in the parallel walls of trapezoidal profile cage bar, promptly form two outer longitudinal edges that have outward extending convex surface (projection), wherein each infall at level and vertically extending cage bar forms four contact points, these contact points couple together after welding securely, and welding back (long) opposing parallel wall has distance each other and is not in contact with one another like this.In prototype, the trapezoidal cage bar recessed along its whole length is proved to be outstanding especially in it uses.
In the modification of embodiment, the longer parallel walls of trapezoidal profile pipe bar only inwardly concaves in the part, intersection region, and the longer parallel walls of another laddertron bar inwardly concaves along whole length.This may be enough fully for steady component of stress load.The recessed degree of depth of longer parallel walls die mould is about one of moulding pipe bar thickness and arrives twice (about 1 millimeter to 2 millimeters); In the palette container of reality, moulding pipe bar wall thickness is 1 millimeter, and recessed degree of depth A also is 1 millimeter, weld like this back-cage bar contact point that intersects whereby fuse into each other about 1 millimeter-at each point of crossing, about 1 millimeter of long parallel walls phase mutual edge distance respect to one another is not even be in contact with one another after the welding yet.This is a particular importance, because therefore palette container also is exposed in the natural environment of weather in outdoor storage usually.By between the cage bar of weld nugget, having spacing,, the rainwater that gathers also prevented the formation of becoming rusty substantially thereby being easy to arrange light.If face of weld contact then can form rust inevitably, cause when the short time cage bar rust in a large number.
In another special design plan of the present invention, there is being a distance that at least one indenture is provided with each weld nugget in the longer parallel walls of laddertron bar side.This indenture has reduced the height H of pipe bar, thereby has alleviated the dynamic vibration stress that acts on the responsive weld nugget and the threshold peak of various flexure stresss.According to the present invention, near weld nugget, provide an indenture in each side of laddertron bar, the distance of indenture and solder joint is at least 1/10th of pipe bar width B.Like this, when dynamic vibration stress took place, the critical tension peak value was transferred to the adjacent area that certain distance is arranged with weld nugget from weld nugget.By this special structure, promptly manage the indenture that bar band and solder joint have transverse distance, reduce peak stress whereby, obviously reduced acting on static state or the dynamic stress that is welded to connect, wherein solder joint is at deforming zone, thereby kept their high-flexural strength.Compare with known tubes bar profile and according to the present invention, the pipe bar is not local recessed at weld nugget, but each impression or indenture be positioned on profile homonymy and/or the opposite side and with weld nugget a distance arranged, with bending sections modulus that reduces relative point of crossing and static state and/or the dynamic stress of removing cage bar weld nugget.Trapezoidal profile is configured to it and can be easy to be recessed into and do not have wide variety of materials to move.The indenture of pipe bar (=impression, perhaps recessed, form " vibrating elements " as desired) only is provided at tubular specific region, whereby attenuative effect on the point of crossing of welding or four weld nuggets vibration stress and the crooked peak tension of fluctuation.When with a pipe bar and second pipe bar weld together, follow the pipe sclerosis of material embrittlement in this position, make the pipe bar responsive especially to vibration stress at this point.For example the sizable vibration stress that exists with truck transport the time can cause solder joint fracture or pipe bar originally to rupture in solder joint in the shortest time.According to the present invention, cage type bar-support overcoat is such structure, and promptly " oscillation point of hope " is not just in time to be positioned at point of crossing or point of crossing adjacent domain, but with the solder joint of infall certain short range is arranged at least.Oscillation point by forming the hope that indenture sets up is under any circumstance all less than 50% of pipe bar cross-sectional plane.They are arranged in 10% to 45% scope of pipe bar cross-sectional height, preferably are about 1/3 (33%).Therefore the bending strength with indenture pipe bar reduces slightly, but the sensivity of the fracture that fatigue is caused greatly reduces.

With Reference numeral 10 expressions shown in Fig. 1 is according to palette container of the present invention, it shows the thin-walled blowing rigidity endogenous pyrogen made from thermoplastic material (HD-PE) 12 of band upper inlet and closely surrounds the cage 14 that endogenous pyrogen is made up of the cross pipe bar, wherein said cage securely-but detachably or interchangeably be connected on the base supporting plate 16.Shown in front elevation show the narrow side of palette container 10, be arranged in outlet valve on the plastic container 12 near base.Outlet valve 18 is arranged in here above the following front edge of the base supporting plate 16 that structure illustrates as wooden supporting plate (US Runner), the vulnerable point of palette container has been represented at described edge, in homologation test, particularly in the diagonal angle impact test process, this edge is subjected to maximum stress.The special tectonic of band indenture (referring to Fig. 7) cage bar is illustrated in the circle.
Before exploitation was according to palette container of the present invention, five kinds of known and different palette containers that can obtain on market had been accepted accurate relatively stress test (vibration test, the pressure capacity test divides other stacking ability test for internal pressure test, impact test).In a series of vibration tests that simulation long-distance transport truck transports, can isolate some particular frequencies that weakness in various rectangle overcoats, all occurs on bad road.
Be test objective, also deliberately make shown in Fig. 2 test palette container 10 (shown in do not have the elastic reinforcement indenture) accept the continuous over loading test, the point of also having showed mark on level and vertical cage bar in the drawings with circle, according to the dynamic vibration stress amplitude ratio than test results (referring to Figure 10,11), these points at first lost efficacy and began fracture.
Fig. 3 shows the intersection region according to sealed tube bar profile 18 of the present invention, a trapezoidal cross-section, extend parallel to each other one than longwell and one than shortwall 20,22 and two straight walls 24 that incline towards each other and extend, these two straight walls are connected than on the shortwall 22 from longer parallel walls 22 beginning diagonally extendings, two straight sidewalls of the profile 18 of extending of inclining towards each other whereby form a drift angle 26, and drift angle preferably is about 36 ° in 20 ° to 45 ° scope.The height to width ratio of pipe bar trapezoidal profile in 0.8 to 1.0 scope ,-preferably be about 0.86.Because trapezoidal profile height is big (not having bending) in sloped sidewall, realized corresponding high bending stiffness, and because the sealing of trapezoidal profile and compactly designed, compare with circular profile or pipe bar profile with open pro-file structure, this pipe bar shows improved torsional stiffness.Be about the profile height H with drift angle 26 distance that the level of the wall 24 that extends prolongs the axis point of crossing that inclines towards each other, perhaps begin to measure and be about 2H from longer parallel walls 20.Distance can be 0.75 in the 2.5H scope.
The preferred trapezoidal profile of using 18 is illustrated among Fig. 4.In simple mode, longer parallel walls 22 only partly inwardly concaves by this way two pipe bar intersection regions, promptly outside two, formed the convex surface 28 of outside protrusion on each of longitudinal edge, each infall at level and vertical extent pipe bar has formed four contact points like this, they are connected to each other after welding securely, manage bar junction (longer) respect to one another even parallel walls 22 also separates each other at each after welding whereby.
In a particularly preferred embodiment, longer parallel walls 22 all inwardly concaves on the whole length of pipe bar, and the convex surface 28 of outside protrusion is provided for two outer longitudinal edges whereby.The pipe bar that has with the trapezoidal profile 18 of continuous indenture is proved to be outstanding, and is to be that the tube model of 18 millimeters (circumferential length is 56.55 millimeters) is made with diameter.Vertically the indenture degree of depth of profile should be about a times or twice (about 1 millimeter to 2 millimeters) of pipe bar wall thickness; In the palette container that is completed into, pipe bar wall thickness is that 1 millimeter and the indenture degree of depth are 1 millimeter.Welding in four contact points of each infall of pipe bar on each realizes by resistance pressure-welding.When carrying out four spot weld, the cage bar of intersection is pressed together about 1 millimeter, even about 0.5 millimeter to 2 millimeters of mutual distance still after 22 welding of the relative parallel walls of each infall so preferably is about 1 millimeter and do not contact mutually.(distance A=1 millimeter).This is unusual the important point, because palette container usually is housed in outdoor and is exposed in the weather.By the cage bar is spaced apart from each other at weld nugget, the rainwater that the there may accumulate is by being exposed in the air by air-dry, thereby and prevented rustization substantially.The face of weld that is abutted against each other is easy to form rust inevitably, and this can cause whole cage serious rustization in the shortest time.Also clearly showed in the cross sectional view outwards between the cocked bead 28 width of remaining (longer) parallel walls 22 approximately equal with the width B 1 of relative (shorter) parallel walls 22.
The schematic diagram shows of Fig. 5 because the distortion skew that the cage type overcoat that dynamic vibration stress produces changes.The fluid of fluid-load presses-is illustrated in right-hand side-about Loaded goods center of gravity S height in quiet in Fig. 5, promptly about 33% of the cage height produce maximum cage and be offset D
a, D
i, and outside amplitude is about the twice of inside amplitude on this height, and Here it is in the vibration stress process, and the crackle in the cage pipe is formed on the subregional reason of cage lower part, and this is the most dangerous.
Among Fig. 6 the schematic diagram shows of local section diagrammatic sketch maximum distortion effect D
aAnd D
iThe level cross-sectionn of position.The outside vibration skew of direction is not interfered, and inwardly fluid column then runs into relative sidewall.Therefore, the circumferential horizontal cage bar 30 in bottom is subjected to big flexure stress at turning, turning 38 especially.
Fig. 7-with the point of crossing 36 of cage inside view-show levelling pipe bar 30 with vertical tube bar 32.Four solder joints have been pointed out at point of crossing 36.The laddertron profile of horizon bar 30 and vertical rod 32 has formed four solder joints respectively having an indenture 34 near each side of point of crossing 36 respectively, and indenture 34 separates to 1/10th of education and correction for juvenile offenders bar width B with point of crossing 36 whereby.Be illustrated among Fig. 8 along the trapezoidal profile 18 of the not distortion of direction of observation D, the diagrammatic sketch of the indenture 34 of C-C along the line is illustrated among Fig. 9.Indenture 34 in the pipe bar can be formed on (" longer ") parallel walls 22 sides or/and be formed on relative (" shorter ") parallel walls 20 sides.Therefore, various distortion can be realized, the outside of trapezoidal profile can be provided at or/and two indentures also can be provided at the inboard at least two indentures of two cage bar point of crossings like this.But the most important thing is that for these embodiment the pipe bar is not directly in point of crossing or the recessed or distortion at solder joint respectively, but only with these places the recessed or distortion in a distance is being arranged.When reducing the profile height H, if possible, it is low that the degree of depth T of an indenture 34 should keep, promptly in 15% to 50% scope; In a preferred embodiment, indenture degree of depth T is about 33% of profile height H.Indenture 34 should be in the half as much again to three that is about the profile width B times scope along the longitudinal extension of bar, and in a preferred embodiment, the longitudinal extension of indenture 34 is about the twice of profile width B.
Figure 10 shows along what whole length of tube had a square profile and is not subjected to stress known type cast face.As shown in Figure 11, after being subjected to the dynamic vibration stress of short period, just point of crossing can see horizon bar 30 ' on formed the crack, these cracks all lay respectively on the solder joint.
The formation in crack or cage bar tear the zone that occurs in the pulling force maximum all the time, perhaps occur in the cage type overcoat and protrude maximum place.The vertical tube bar is arranged in cage type overcoat inboard, and the levelling pipe bar is arranged in the outside.Crack and breaking-down point occur in the intersection region of close solder joint (with reference to band circle diagrammatic sketch among the figure 2) all the time.The crack that on the vertical tube bar, begins to form-relative overcoat-be to propagate to the inside from the outside all the time, and be to propagate laterally from the inboard beginning of horizon bar all the time.In comparative test, have been found that with open pro-file and have cage type overcoat that the cage bar of straight outside hypotenuse makes because solder joint mutual distance in infall is far away, thus show good stacking ability, but they are worst to vibration stress.
In Figure 12, to compare with the square tube profile, sealing laddertron profile 18 according to the present invention has two indentures 34 on horizon bar 30.As among Figure 13 with shown in the exaggerative mode, even suffer vibration stress also not form the crack for a long time.On the one hand, this is because thereby the solder joint of intersection region does not cause the indenture of weakness highly stable, on the other hand, indenture 34 has reduced section modulus and has played a bit effect of " flexure hinge " when from point of crossing at least one small distance being arranged, thereby prevents that peak tensions from acting on the responsive solder joint and make peak tensions to farther Hookean region skew.
The specific question of constructing special cage type shell embodiment is that vertical and horizontal cage bar should be stablized with firm as far as possible to prevent excessively protruded by the palette container of interior pressure effect; On the other hand, should provide high bending sections modulus offsetting constant dynamic vibration stress, thereby above-mentioned two standards are opposition mutually.Considering favourable situation, during as low production cost, must find best solution.According to recent trend of the present invention, known palette container has along the smooth cage bar of pole length profile, according to DE 297 19 830 U1, they may be suitable as storage container as for example, but are not suitable as the container of the peril of transportation load fluids thing that bears dynamic vibration stress.
The patent documentation of quoting previously is based on prior art, and known palette container has the cage type overcoat with the circular cross section pipe manufacturer, and pipe has indenture at the pipe point of crossing of welding at least." having avoided local tension force accumulation by the profile pipe (there) that uses according to the present invention (not with any local indenture) ... " claimed in description on the 2nd page of this patent disclosure but it does not have correctly to illustrate the recent trend among the present invention, and only show that when the cage type overcoat of this palette container is subjected to transporting stress the inverse relationship effect is not considered between bending strength and the vibration elasticity.
According to the present invention, the degree of depth T of trapezoidal profile indenture 34 be about pipe bar profile height H 25% to 50% between, preferably be about 33%.Enough usually for the indenture of 5 millimeters of pipes that highly is 15 millimeters, the vibration stress of solder joint keeps low or is eliminated whereby, has kept sufficiently high rigidity simultaneously in pipe.It is important that this rigidity remains on low-level for the horizontal protrusion amplitude that will vibrate cage.
Figure 14 shows the embodiment that has two indentures 34 deviating from the pipe bar profile side of the solder joint of lacking parallel walls 20, and-as shown in Figure 15-it shows change and the useful especially modification of this embodiment.Laddertron profile 18 has indenture 34, and indenture accurately lays respectively at shorter parallel walls 20 sides and longer parallel walls 22 sides of laterally close point of crossing 36 relative to one another.Here the distance of indenture and point of crossing 36 is about 1/10th of pipe bar profile width B.Indenture is arranged in " hinge effect " or the elasticity of having strengthened the cast face on each in the sidewall 20,22 that extends in parallel especially.
According to technology theory of the present invention, according to the dynamic stress intensity that expection on the cage type overcoat 14 is born, the structure of indenture 34 can have the different degree of depth in level and the vertical tube bar 30,32.Therefore,, keep enough bending strengths simultaneously according to special requirement or needs, can be in the various zones of cage type overcoat, for example at the longer sidewall of palette container, the optimal vibration elasticity in the perhaps short preceding and rear wall in controlling level and the vertical tube bar.
Figure 16 shows another important embodiment of the dynamic vibration stress ill-effect that is used to reduce the levelling pipe bar.At 90 ° of corner regions and be parallel to vertical direction, the levelling pipe bar 30 of cage type overcoat 14 flattens, and makes them also play " bending joint " effect of hinge form.At corner region, levelling pipe does not need to have high resistance to bending, the more important thing is higher elasticity here.Realized particularly advantageous test results by such palette container, promptly the levelling pipe bar 30 of palette container at the corner region 38 that supports overcoat 14 from inboard and/or be driven plain 1/4th of profile 18 diameter height H at least from the outside.In an embodiment of actual configuration, the levelling pipe of cage type overcoat bottom is driven plain about 20% and be driven plain approximately 35% from outer turning circular arc from the inboard, and the pressing amount of cage type overcoat upper area reduces gradually.
Here be noted that and schematically and large showed essential characteristic of the present invention in the accompanying drawings, they should not be understood as that restrictive, and only are to understand better in order to show purpose and to be convenient to the viewer.
Should be appreciated that, shown in modification can make up in every way, and other combination is also included within the spiritual scope of the present invention.Above-mentioned possible modification, particularly cage type overcoat bottom can have different devices to realize having the elastomeric enough bending strengths of pipe bar of best-fit.
