Description

Loading device for trucks eugaufbauten The invention relates a loading device for truck bodies with one up to the height of the loading area liftable, flat lifting platform, which can be used as an opening in the loading area of the structure entering bottom part is formed and with a support and lifting device Is provided. Under truck bodies, the bodies are in particular of trucks, their trailers, but also of articulated vehicles u0 like. understood, the superstructures-either firmly connected to the vehicle frame or can be detachably connected to the vehicle frame as swap bodies0 The superstructures can be designed to be open or closed.

Lifting platforms are used on such vehicle bodies to Load from the ground, a ramp or the like.

to raise or lower to the level of the loading area, so that the The driver alone can load and unload.

In an arrangement of this type known from DAS 1 224 203 which the lifting platform is part of the floor, it can be made very flat and therefore be designed without a pivoting device. For that, however, are inside of the vehicle and on the lifting platform, which are structurally complex and take up a lot of space Straight guides required, the practical use and above all the use make it very difficult or impossible to use on any structure. Other Similar loading devices with vertical straight guides according to OS 2 105 279 take up even more space inside.

The particular from DT-PS 961 877 and its practical application known, so-called tail lifts use a swiveling side wall of the body, usually the back wall, as a lifting platform and have to face the loading area The two articulation axes for the parallelogram arms end on top of each other. To a certain extent To achieve stability, these articulation points must be spaced a considerable distance from one another lie so that the outer end of the lifting platform protrudes from the ground and usually therefore special precautions must be taken to keep the end on the ground to pivot, for example toggle levers or special hydraulic cylinders used. The construction with a view to the often large loads to be lifted Making it reasonably stable is a very heavy and costly implementation with appropriate control devices required, the present leads to such a high price that the use of such drop sides on smaller ones and cheaper trucks are grossly disproportionate to the total price. The boob and guide arms are relatively long and within the lateral ones Articulated limitation of the lifting platform. For lifting platforms that are in a.

Moving the bottom opening into it is one such lifting and supporting device neither known nor suitable.

The invention is primarily intended to avoid the aforementioned disadvantages, Among other things, the advantages listed below are achieved and the advantages of known lifting devices as far as possible. The invention is based on the object of a charging device of the type mentioned in such a way that with a very flat lifting platform and the elimination of pivoting devices that is made possible a very stable one and yet lightweight and therefore inexpensive lifting and carrying device created wiTa, that does not affect the cargo space and on a wide variety of vehicle designs can be attached without difficulty. According to the invention it is provided that the support and lifting device with known per se running next to the lifting platform, Parallelogram-like arranged lifting and guide arm pairs is formed, which on a storage arrangement that is fixed to the vehicle between the lane and the loading area and are hinged to the lifting platform and connected to a lifting device and their articulation points on the bearing arrangement and on the lifting platform in itself known way lie in planes essentially parallel to the loading area and the are connected on each side by a coupling whose linkages to the lifting and guide arms' outside the Straight lines connecting the articulation points each arm are offset in the direction of one arm.

Since the lifting and guide arm pairs are only below the loading area move, they do not affect the cargo space in any way. Since they are below the The loading area is fixed to the vehicle and can easily be attached to a wide variety of Vehicle frame structures, which are generally stable at this point anyway and allow the connection of additional units, well and easily attached be so that the considerable forces without any particular burden on the / yuitautelle can be included. Because the articulation points are parallel to the loading area, So usually horizontal planes lie, the arrangement can be on a very flat or thin hat platform are provided, so that a pivoting in the lowest Location is omitted. Nevertheless, there is a very large support base and therefore good stability possible even with a relatively light and inexpensive construction. The outside the connecting line articulated coupling causes that even when passing through the extended position does not tip the lifting platform. Similar lifting mechanisms in terms of kinematics and support devices with pivot points lying in horizontal planes are for other purposes, such as lifting the entire vehicle body or swinging it over of the same known. However, it has not yet been recognized that this construction can be used can be modified and used with lifting platforms attached to the vehicle body and thereby a very light and elegant, but stable construction achieved Above all, it allows a lifting platform to be placed very close behind the storage arrangement to enter an opening let so that they also apply to vehicles can be used with a low UDerstand over the fastening device.

While with the so-called tail lifts known so far, the articulation Always done at one end, it is now possible and especially for stability expedient that at least one point of articulation on each side of the lifting platform near the center of gravity because the articulation takes place laterally and the two articulation points are not one above the other, but lie one behind the other. It is useful to steer the lift arm close to the center of gravity on the Habpláttform, while the guide arm can be a little further away.

While with the usual tail lifts, the distance between the pivot points on the lifting platform was very low because of the articulation on top of each other and therefore only a very small bearing clearance could be accepted and a stable one Arm and bearing construction was required, the distance between the articulation points can be the loading device according to the invention more than a tenth of the length of the lifting platform be. About a quarter of the lifting platform length or half the lifting platform length offer inexpensive support bladders for reliable, simple constructions.

While the previous ParaTlelogrammanlenkungen of so-called Tail lifts could only use relatively small swivel angles in order not to to get into areas in which one almost reaches the extended position of both pairs of lever arms and thereby even with relatively little play due to the elasticity Of the parts has to fear the lifting platform tipping over, it is According to the invention, it is now possible to match the stroke height and length of the ear to one another in this way agree that the arms and the lifting platform cover a large pivot angle and the lifting platform in the final phase of the upper movement a relatively large horizontal movement executes. This results in a very compact design with a lighter and still more stable Construction possible. This can also be used for the lifting platform in the lower position not or only a little over the outer edge of the vehicle protrudes, which makes it possible to use lifting platforms on trucks even with narrow to use inner-city parking conditions, so that the usual tail lifts recurring deficiency that shortly after stopping immediately behind the Vehicle the space is occupied by another vehicle and unloading is impossible power is avoided.

The lifting platform according to the invention can, as for other constructions known, to be provided at the rear or on the side of the loading area. Is it provided in the back, so it can be used without swinging too far. The side arrangement is Mainly possible because of the large swivel angle and because you can use the loading platform now with stable conditions in the upper position relatively large horizontal movements can be carried out and thus enables a lifting platform of sufficient size, which also performed favorably when the vehicle frame is relatively far out can be. If necessary, the end protruding beyond the articulation can be used Set down on the underside or be inclined so that it just passes the vehicle frame can be.

Since the lifting and guide arms pass through the extended position, the Articulations be designed accordingly. One can see the articulations as flying Form bearings on bolts, which, however, make the joints very heavy requires. The flying storage on the lifting platform can be avoided if one on each side of the lifting platform a boom encompassing one articulation point provides where the other articulation point is located. Then one arm can between Lifting platform and boom are stored, while the other with a fork-like Joint is attached to the end of the boom.

This also simplifies the mounting arrangement fixed to the vehicle because there then no overarching arms and no kinks are required are, especially since the lifting arms are anyway od by a torsion-proof tube.

will connect in order to achieve synchronization of both sides and to be able to arrange the lifting device at any point.

However, if you want to avoid the boom on the lifting platform, you can here the arms are hinged with simple bolts, while on each side the vehicle-mounted storage arrangement, a boom is provided on which a point of articulation is located.

The arms can expediently be angled in the area of the coupling linkage will. Then a full wishbone need to be used which is very heavy would be. You can also grasp the holding ring well and. has on the other hand next to arm parts that are not too high on the loading platform in the lower position.

According to a further advantageous embodiment of the invention can be inclined to the lifting direction of movement on the loading area and / or on the lifting platform Lead-in surfaces are provided. Then you need the lifting and guide arm pair construction with regard to lateral mobility, it is not designed to be excessively stable and free of play to become, especially since slight lateral movements during the lifting process are not annoying. However, on the other hand, very precise entry is achieved with very simple means the lifting platform in its floor opening, in which it is like an insertion funnel is introduced and then occupies a precise sealed position, so that the Entry of dirt ifl the hold can easily be prevented. To when introducing the lifting platform into the floor opening pushing apart the floor opening To prevent limiting parts of the loading area by the wedges, one can use appropriate Provide brackets that come into engagement when the lifting platform is raised and when Conversely, lowering can then be automatically moved apart again. One special simple design for this provides projections on one part, their contact surfaces run in the lifting direction and hooks on the other part, which are over when lifting slide the protrusions. The insertion surfaces and the clamps can be seen appropriately at the outer ends of the loading surface parts delimiting the floor opening. So becomes a good brace at those places that tend to be most prone to pushing apart achieved that auoh the vehicle body in the vibrations caused while driving and holds movements together well.

Since the lifting platform forms part of the loading area floor, it must Care should be taken that they are not inadvertently while driving lowers; A locking device working with sliding bolts can advantageously be used for this purpose Provide their sliding bolts in the guide surface wedge pieces of the lifting platform are stored and in bores of the insertion surface wedge pieces provided on the loading area Then the massive pieces, which are necessary anyway for the introduction, which are well aligned when entering, for storing the locking elements used. The sliding bolts are expediently connected to a common receiver lock operated, the handle with a moving in the pivoting range of the body doors Securing element is provided. So the doors can only be closed when the lifting platform is actually raised and locked in the correct position is.

In FIGS. 1 to 3, only one frame part 20 of the truck is shown, the wheels 21, a corner of the superstructure 22 and the floor plate 23 of the loading area 24 Shown with dashed lines.

On the vehicle frame lying between the loading area 24 and the roadway 25 20 is a support and connecting tube 27 of the with the help of the fastening tabs 26 Storage arrangement attached. The storage arrangement can also be attached to the structure will. This' has a bearing arm 28 on each side, which is at the outer end of the support tube 27 extends horizontally and is firmly welded to this.

A connecting shaft is rotatably mounted in the interior of the support tube 27, the lifting arms 30 are attached to the two ends of which are connected to it in a rotationally fixed manner. The lifting arm on the right-hand side is connected to an actuating arm 32 in a torsion-proof manner, at the end 33 of which the piston 34 of a hydraulic cylinder 35 is articulated, which in turn by means of the pivot bearing 36 on the. protruding end 37 of the bearing arm 28 is pivotably overhung. The hydraulic cylinder 35 with its associated parts represents the lifting device. Others can Lifting devices, such as pre-static, electro-mechanical or purely mechanical lifting devices to be used.

At the front end 40 of the bearing arm 28 is in a fork bearing 41 the guide arm 31 is mounted pivotably about a horizontal axis. Like Fig. 2 3 and 4, the guide arm 31 lies within the lift arm 30 and is is provided behind the support tube 27 with respect to the direction of travel F. Linkage 29 of the lifting arm 30 and the articulation 42 of the guide arm 31 lie in one plane El, which runs parallel to the loading area 24. It is not absolutely necessary that these planes are exactly parallel. If one wishes to compensate for the Vehicle suspension with different loads and different caused thereby Slopes and to compensate for uneven floors that the rear end of the lifting platform 45 is inclined backwards, the plane El could also be slightly to the loading area 24 be inclined. But then it still extends in the sense of the claim essentially parallel to the loading area.

The lifting platform 45 has a side arm 46 which extends parallel extends to the outer boundary 47 beyond the articulation point 48 and thus the one Articulation point 48 engages. At its end 49 is with the help of a fork joint 50 the lifting arm 30 is articulated to form the articulation point 51. Between the boom 46 and the lateral outer boundary 47 of the lifting platform 45 extends Guide arm 31, which is approximately in the middle of the lifting platform, so near the center of gravity S, is hinged to this at 48, with the help of a not shown in detail, both in the lifting platform 45 and in the boom 46 supporting bolt. This avoids floating bearings. The articulation points 48 and 51 are as Fig. 1 illustrates, in a plane E2 which is parallel to the plane E1 and so that it is also essentially parallel to the loading area 24.

Lift arm 30 and alignment arm 31 are, as FIG. 1 illustrates, triangular designed. Your articulation points 29 and 51 or 42 and 48 lie on the two parallel ones Connecting straight lines V1 and V2. Outside this connecting line, in the direction of Relocated to the lifting arm, each of the arms has a further articulation point 55 and 56, respectively. One of these is floating - as FIG. 2r illustrates - between the two arms horizontal coupling 57 articulated. The articulation points 55 and 56 lie in a plane E3, which in turn are essentially parallel. runs to the loading area 24. The pivot points each level have the same distance. As far as minor pivoting if desired, small deviations from the exact parallelogram shape can be provided The linkages are then to be provided accordingly. On the not shown on the other side of the vehicle is a similar, mirror-inverted arrangement provided by lifting and guide arms with associated parts, so that the lifting platform 45 is carried by these Hub- und Buhrungsarmpaaren 30, 31 and with corresponding Actuation of the hydraulic cylinder 35 moves up and down on the circular paths 60, 61 can be so that they in the raised position in the floor opening 62 of the loading area 24 occurs and thus loads applied to them at this level easily can be moved. Essentially due to the position of the articulation points in relation to the loading area parallel planes, a very large distance between the individual articulation points can be selected so that a great stability can be achieved even with a light construction is. The distance A between the articulation points is almost half the length of the lifting platform HL. The whole arrangement can be equipped with a support tube and attached at will different designed vehicles easily attached with appropriate fastening straps 26 will. Since the articulation points are not on top of each other, but next to each other, can the lifting platform is very flat, so that it only ends up being a small one Drive-up slope is required or can be designed slightly wedge-shaped as a whole, so that they can be loaded or unloaded directly. As FIG. 2 illustrates, lie the lifting and extension arms 30, 31 next to the lifting platform 45 and can move freely move past each other. Since the lifting platform is essentially between the Moving side walls, the user standing on them has a certain feeling of security, what is missing from tail lifts.

The lifting and guide arm pairs on both sides are relatively long and, as FIG. 1 illustrates, only place a relatively small pivot angle return. When driving through the extended position and in the adjacent area, a Tilting of the lifting platform by the articulated outside the connecting lines V1 and V2 Coupling 57 prevented.

The embodiment of FIGS. 4 and 5 is essentially the same built up. The same parts are provided with the same reference symbols. Here are however Lifting height H and arm length L matched to one another in such a way that the lifting and guide arms 30 and 31 as well as the lifting platform cover large swivel angles and thereby the Lifting platform even if the arrangement protrudes little beyond the support device Application can come. Here the lifting platform is not significantly above the articulation points 48 of the guide arms 31 over, but forward over the articulation points 51 of the lifting arms 30, so that they are articulated in the vicinity of the center of gravity S. Otherwise are Articulation, coupling and the like are provided in the same way. The figures illustrate It is very good that the lifting platform is only in the lower 1 position shown in solid lines little, namely by the small amount B over the trailing edge end Vehicle body 22 protrudes. The arcs 60 and 61 illustrate on which Railway the lifting platform 45 is guided. It only swivels backwards a little so that little space behind the vehicle is required for charging and thus the cramped conditions in city traffic is taken into account.

The embodiment of Figs. 6 and 7 works essentially similar. Here, too, short arm lengths / are used, but the lifting arms are 130 and the guide arms 131 not as a full cover corner. but than in the field of Coupling formed angled lever. Also in this exemplary embodiment dispensed with storage with outriggers. The articulation points 48 and 51 on the lifting platform 45 are designed as floating bearings, the guide arm 131 being a longer one Eye 80. This is also on the outside, while the lifting arm 130 is on the inside. here a support tube 127 is provided, which is fastened to the frame 20 with the tabs 26 The connecting tube 129 can also be rotated in special bearing brackets 128 stored, on the ends of which the lifting arms 130 are fastened in a torsion-proof manner, which according to have protruding lugs 132 for the articulations of the piston rods 34. The hydraulic cylinders 35 are on support arms that are particularly inclined upwards 137 hinged, which are attached to the support tube 127. The extreme ends of the Support tube 127 have forward-projecting arms 146 on which the articulation points 42 are provided for the articulation of the guide arms 131. The bending of the arms makes it possible to reach around the bearing and thereby create a construction which is conveniently attached under the rear end of the vehicle frame 20 will can and can also be used well when the vehicle body 22 protrudes slightly can.

While the three embodiments described above for the Attachment to the rear end of the utility vehicle body and for loading from the rear 8 and 9 shows an embodiment for side loading, especially for city traffic and loading from Sidewalk from or from a ramp that is approached from the side is. Construction and articulation of the lifting and guide arms as well as the design of the fastening elements the lifting platform are made as in the embodiment of FIGS. 4 and 5, so that here again the same parts are provided with the same reference numerals. Just is the fastening tab 226 the other assembly case on the longitudinal side of the vehicle frame 20 adapted. The hydraulic cylinder 35 is also on a special bearing piece 237 hinged. Here, too, the guide arms 31 are in the area of the outer enda of the lifting platform 245 articulated, while the support arms 30 are articulated in the area of the center of gravity S. are. However, the lifting platform, as illustrated in FIG. 8, is essential here further inward beyond the linkage. Your inner end 90 is down at 91 beveled or can also be offset so that the lifting platform is just flat Frame parts or other elements of the vehicle can move past if they enters the bottom opening 262 in its upper position.

Here the pivot angle is even greater than in the previous exemplary embodiments and the lifting and guide arms reach an almost vertical position, so that the Initially a very large lifting platform in the upper area Horizontal movement executes and thus also via a located just below the loading area 24 Frame or other structural parts can be swiveled away. This embodiment too shows that the lifting platform 245 in the lowest position is not very far above the Side edge K protrudes.

While FIGS. 1 to 9 only show the supporting and lifting devices with the lifting platform, FIGS. 10 to 14 represent the other ones provided on the lifting platform Parts for insertion into the base opening and for locking and clamping. A vehicle body 22 is shown here, the side walls 101 of which are connected via hinges 102 the rear doors 103 carry the rear over the loading area 24 slightly protrude downwards.

Loading surface parts 104 are provided on both sides of the floor opening 62, between which the lifting platform 45 moves. Since the lifting and guide arms as a result their elasticity allow a certain amount of lateral mobility, are funnel-shaped acting, inclined to the lifting direction insertion surfaces are provided, namely on the front Edge 104 are provided rearwardly outwardly protruding insertion wedge pieces 105, between which the guide blocks 106, which are provided on the lifting platform 45, enter.

On the inner surfaces 107 of the rear ends 108 of the loading area parts 104 insertion surface pieces 109 are attached, the insertion surfaces of which face down run outside.

Corresponding counterparts 110 are in the corresponding area on the Outer surfaces 111 of the lifting platform 45 attached with a corresponding inclination. Be like that when lifting small lateral deviations compensated for Push up of the lifting platform, the loading area parts 104 due to the lack of a rear cross connection could be pushed apart and especially movements and vibrations during occur while driving, cross brackets are also provided. For that are on the rear end faces 112 of the loading area parts 104 projections in the form of welded-on Round bolts 113 are provided, which extend vertically, that is, in the stroke direction. On the rear face 114 of the lifting platform 45 hooks 115 are attached, the with their holding parts 116, over which the projections 113 grip. As the contact surfaces run in the lifting direction, come from the projections 113 and the hooks 115, 116 formed brackets automatically to engage. The lead-in surface wedge pieces 109 and 110 act in such a way that they have a firm contact between the projections 113 and the hook parts 116 cause a very rigid good cross connection on the outer rear end of the vehicle body is achieved, which is a cross member is equivalent. 13 shows only the lines lying in the cutting plane in a position shortly before reaching the upper end position of the lifting platform 45, from which the insertion process can be seen. Since a certain space Z between the outer edge 111 of the loading platform and the edge 107 of the loading surface part 104 is required to accommodate the lifting and guide arms and joints, the vehicle floor has a cover plate 125, which may be for safety reasons can be designed to be articulated.

It covers the space Z and lies in a circumferential one Groove 126 of lifting platform 45.

While FIG. 13 shows the arrangement in a released state, the arrangement is illustrated in the other figures in the locked state. To this one to fix the locked state with certainty a locking device with sliding bolts 117 is provided, which in bores 118 of the insertion surface wedge pieces 110 attached to the lifting platform 45 and enter into corresponding bores 119 of the insertion surface wedge pieces 109 can, if the push rods 120 of the Baskül lockes 121 with the help of the handle 122 to be moved. To be on the safe side, the handle 122 has a securing element on the shaft 123 attached, which, as FIGS. 10 and 12 illustrate, is in the pivoting range the door 103 is moved toward when the latch 121 is opened. So can the doors 103 are only closed when the lifting platform is properly raised and is locked. While these insertion and locking elements for the rear Arrangement of the lifting platform were shown, can be the same or similar Arrangements can also be used for a laterally provided lifting platform. Despite of these facilities is the construction floor or its frame in the area of the floor opening to train quite torsionally stable.
