Definitions

  • the invention relates to a lifting table for lifting and lowering heavy loads according to the preamble of patent claim 1.
  • Lifting tables of this type are known in various designs in industrial conveying and manufacturing technology; they generally serve to move a load from one height level to another height level.
  • lifting tables are used to introduce bodies into treatment stations and to remove them from them.
  • the introduction can be done by lowering, for example, in a bath, and the removal by lifting, so escape from the bath.
  • the introduction may also include a lifting movement, for example, when introduced into a dryer, and a lowering movement during deployment. Lifting movements are also often necessary when transferring from one conveyor to another.
  • a lifting table of the type mentioned is for example from the DE 26 19 347 A1 known.
  • the upper structure is connected via telescopic guides with the substructure; Shear-type levers transmit the force exerted by a hydraulic cylinder to lift the top structure.
  • a jack is in the FR 2 770 835 A described which makes use of the elastic properties of deformable parts.
  • Two bulbously shaped parts hingedly connected at their ends have at their end regions flexibly formed zones, which are connected to one another via a rigid zone.
  • a motor-driven threaded spindle engages in a sleeve, which is arranged in one of the articulated ends. By rotation of the threaded spindle, the hinged ends can be moved towards each other, whereby the rigid zones move away from each other, so that the jack performs a lifting operation.
  • the ability to absorb tilting moments is limited.
  • Object of the present invention is to make a lifting table of the type mentioned so that the force is generally under more favorable geometric conditions and the costs are lower.
  • the invention makes use of the fact that elastically deformable profile elements, which have a suitable initial shape, are deformed by application of a lateral force such that their perpendicular to the direction of the force Dimension is increased. Taking away the external force, the profile element returns elastically to its original shape.
  • Such elastically deformable profile elements can be comparatively inexpensive, for example made of fiber-reinforced plastic but also of metal, especially steel.
  • the horizontal driving forces are - as in the prior art in the above-mentioned jack known - when using the profile elements according to the invention cheaper in the vertical movement of the upper structure to, as is the case with the known scissor or Exzenterhubtician.
  • at least two profile elements are arranged side by side to increase the carrying capacity of the lifting table. In this way, relatively flat but large lift tables can be achieved.
  • the hub according to the invention lifting tables is - compared with scissor lift tables - from home not too big.
  • this disadvantage can readily be accepted in many applications, especially since there are measures that can lead to an increase in the stroke and are explained in detail below.
  • the power source may comprise a motor and a horizontally extending threaded spindle driven by the latter and a threaded nut which can be screwed onto the threaded spindle and which is in frictional connection with a lateral region of a profile element.
  • This type of power source is used where forces are to be exerted on the lateral region of the profile element in both directions, that is, tensile and compressive forces.
  • the power source may comprise a motor and a drum driven by this, on which one with a lateral region a flexible element connected to a profile element, for example a cable, can be wound, which runs horizontally at least in the region adjacent to the profile element.
  • the drive via a flexible traction means is even more cost-effective, space-saving and variable than that via a threaded spindle.
  • the flexible traction means for multiplying the force can also be guided flaschenzugartig.
  • the force which serves to elastically deform the profile elements is introduced on one side on a lateral region of a profile element.
  • this unilateral nature of the introduction of force has the consequence that the upper structure simultaneously moves to a certain extent horizontally during its vertical movement. This is easily acceptable in many cases.
  • a horizontal movement of the upper structure occurring simultaneously with the vertical movement can be avoided by virtue of the fact that the force can be introduced on two opposite lateral areas of the same profile element or different profile elements.
  • the vertical movement of the upper structure relative to the substructure is associated with a relative movement between the connection structure and the upper structure and between the connection structure and the substructure, at least in certain areas. So where this relative movement takes place, the choice of materials should be made so that only a slight friction occurs.
  • Adjacent profile elements can abut each other directly with lateral areas. This design is chosen when a maximum surface load is to be achieved for a given area of the top structure.
  • adjacent profile elements may have a lateral distance from each other.
  • adjacent profile elements may be connected to each other by at least one force-transmitting spacer.
  • At least one area of at least one profile element is preferably immovably connected to the substructure and / or the upper structure.
  • Such a type of connection can serve to define the position of the connection structure between the substructure and the upper structure, ie to ensure that the entire connection structure does not shift during a lateral application of force.
  • An immovable attachment of a lateral region of a profile element can also make sense where several profile elements are used side by side, but not adjacent to each other and are not connected to one another via a separate force transmitting spacer.
  • the reaction force on the lateral, deforming force is introduced in this case via the non-displaceable edge region of the profile element in the upper or substructure.
  • the stroke which can be achieved with a lifting table according to the invention, can be increased by arranging at least two profile elements one above the other. In this case, add the strokes that are achievable with each of the superposed profile elements.
  • the superimposed profile elements can be arranged either in the same direction or in opposite directions.
  • the term "in the same direction” is understood to mean the same orientation of the two profile elements in space, while in an opposing arrangement, one of the profile elements is rotated through 180 ° so that its upper side becomes the lower side.
  • the lift table may be composed of two superimposed sub-lift tables, each of which has a sub-structure, a connection structure and a top structure.
  • This embodiment of the invention allows a modular assembly of a lifting table depending on the desired stroke size of a plurality of identically constructed Unterhubtica, which are basically all functional on their own. It is possible that all "Schhubtician” are operated synchronously in the "total lift" by one and the same power source; Alternatively, it is also conceivable that different Unterhubtician be operated separately from each other by separate power sources.
  • At least one profile element at an upper or lower vertex area, with which it bears against the substructure or on the upper structure or on the vertex area of another profile element is provided with a rib-like projection which forms a flat bearing surface.
  • the rib-like projection can also be a separate, subsequently connected to the profile element part, which consists of a low-friction plastic.
  • At least two profile elements may be provided at their lateral, abutting areas with a rib-like projection which forms a planar contact surface.
  • At least one profile element is open on one side.
  • “unilaterally open” is meant here a profile shape having free edges on the bottom or top.
  • Examples of such “unilaterally open” profile elements are those which have the shape of a circular cylinder partial circumferential surface own or roof-shaped.
  • connection structure relatively small, modular components composable components can be used. In individual cases, however, it may be cheaper if at least two profile elements are integrally connected to each other. This design principle can be carried so far that eventually the entire connection structure is integral.
  • the at least one profile element can also be designed like a tube. To lift the upper structure of this hose-like profile element is effectively "squeezed" in the horizontal direction.
  • Tubular profile elements used in the present invention may be open at opposite ends. This makes it possible that the air trapped in the interior of the profile element escapes during the deformation of the profile element and in this way has no influence on the Verforlnungseigenschaften of the profile element.
  • the tubular profile element is closed all around.
  • the included in the profile element Air is thus trapped, so that it must be compressed, for example, at a caused by the deformation volume reduction. It contributes in this way to the deformation characteristics of the profile element and can, for example, affect the load capacity of the entire lifting table.
  • the effect exerted on the deformation characteristic by the trapped air volume can be changed in one embodiment of the invention by adjusting the pressure of the gas trapped in the profile element.
  • the profile element contains at least a variation of its wall thickness. Relatively thin areas of the wall of the profiled element are easier to deform than adjacent, thicker areas.
  • One possible application of this principle is to introduce so-called "thin-layer hinges" around which two adjacent regions of the profile element can perform a type of rotary movement.
  • a lifting table is shown in a schematic manner, which is generally designated by the reference numeral 1 and is intended primarily for lifting and lowering heavy loads with a small stroke.
  • this lifting table 1 also comprises a substructure 2 which can be fastened to a floor or another supporting structure, a load-bearing upper structure 3 and a connecting structure 4 arranged between the substructure 2 and the upper structure 3.
  • the substructure 2 has in the illustrated embodiment, two parallel C-beams 2a, 2b, while the upper structure 3 as a flat support plate with double-folded longitudinal edges 3a, 3b is configured.
  • connection structure 4 in turn comprises three shell-shaped profile elements 5, which in the in FIG. 1b illustrated, relaxed state represent the shape of rectangular sections of a circular cylindrical surface with relatively large radius.
  • the axes belonging to the cylinder jacket surfaces run perpendicular to the extension direction of the two parallel profile carriers 2a, 2b.
  • the axially parallel edges of the profile elements 5 are each secured in a manner which will be described below with reference to FIG 2, in a bar 8, which is guided with its opposite ends respectively in the two profile beams 2a, 2b slidably. If it is to be prevented that the overall arrangement of the profile elements 5 and the strips 8 can move along the profile beams 2a and 2b, one or two adjacent strips 8 can also be fixed to the profile rails 2a, 2b. In the following, it is assumed that the in FIG. 1b the leftmost strip 8 attached to the profile beams 2a, 2b, for example, is screwed.
  • a respective rib-shaped projection 14 is integrally formed with a flat bearing surface. If the upper structure 3 is simply placed on the support surfaces of the projections 14, this results in the FIG. 1a illustrated, compact image of the lifting table 1.
  • the profile elements 5 are made of elastic material, for example made of sheet steel, but preferably made of fiber-reinforced plastic. Will the indicated by the arrow 25 in FIG. 1b taken away shown force, therefore relax the profile elements 5 again and are under displacement of the movable strips 8 and the upper structure 3 in the in the FIGS. 1a and 1b shown position returned.
  • the elastic forces acting in the profile elements 5 cooperate with the weight forces resulting from the load and the upper structure 3 itself.
  • the contact surfaces of the rib-like projections 14 between the retracted position of the lifting table 1 after the FIGS. 1a and 1b and the extended position after the FIGS. 1c and 1d not all move laterally (horizontally) to the same extent, it is ensured by use of suitable materials or other measures that the contact surfaces of the rib-like projections 14 can slide smoothly along the underside of the upper structure 3 along.
  • the least moving projection 14 can be fixed to the upper structure 3.
  • FIG. 2 shows how two adjacent Profile elements 5 - , 5 'with their adjacent longitudinal edges on two strips 8, 8' are fixed.
  • Each profile element 5, 5 ' has for this purpose at its longitudinal edges in cross-section annular fixing ribs 17, 17', which in cross-sectionally semicircular grooves 19, 19 'of the two strips 8, 8' are inserted.
  • the fastening ribs 17, 17' rotate like an angel in the associated grooves 19, 19 'of the strips 8, 8'. In this way, excessive local deformations and forces in the region of the edges of the profile elements 5 are avoided.
  • the advantage of this type of force introduction is that the upper structure 3 does not move substantially parallel to the profile carriers 2a, 2b (lateral); it can then even be attached to the rib-like projection 14 of the central profile element 5. Here, in this case, no relative movement takes place between the upper structure 3 and the profile element 5.
  • the number of profile elements 5, which is used in a particular lifting table 1 is not limited. In individual cases, a single lifting element 5 may be sufficient. In the case of large lifting tables 1, a large number of profile elements 5 can also be used.
  • FIG. 3 an embodiment of a lifting table is shown, which is similar to that of the above with reference to FIGS. 1a to 1d has been described. Corresponding parts are therefore identified by the same reference numeral plus 100.
  • a substructure 102 which is designed here as a plate, as well as an upper structure 103, which is likewise designed as a plate.
  • the connecting structure 104 here comprises only two shell-shaped, downwardly open profile elements 105, whose longitudinal edges parallel to the axes of the circular cylinder lateral surfaces are each fastened in a strip 108.
  • the attachment is done in the same manner as described above with reference to FIG 2.
  • the strips 108 are, with one exception, which will be discussed below, slidably guided on the floor structure 102 in a manner not further explained perpendicular to its longitudinal extension.
  • connection structure 104 of the embodiment of FIG. 3 two rigid spacers in the form of rods 121 which are inserted between the mutually facing inner strips 8 of the two profile elements 105.
  • the leftmost bar 108 is again intended to be fixed.
  • the two profile elements 105 similar to in FIG. 1 with reduction of the radius of curvature and by raising their crest lines and the superstructure 103 lying thereon.
  • the extended position of the lifting table 101 is in the Figures 3c and 3d represented, which probably need no further explanation.
  • lifting tables 1 and 101 can understandably only achieve a relatively small stroke. An increase in this stroke is possible because simply several such lifting tables 1 and 101 are superimposed and form in this way a new lifting table 201, as in the FIGS. 4a to 4d is shown.
  • the lift table 201 consists in this case of two "Schhubtica" 101, 101 'of in FIG. 3 illustrated type, wherein the substructure of the upper lift table 101 is placed on the upper structure of the lower lift table 101 '.
  • the two Unterhubtician 101, 101 ' can be operated either simultaneously from the same power source or by independent power sources.
  • the maximum stroke of the lifting table 201 corresponds to the sum of the strokes of the individual sub-lift tables 101, 101 '.

  • the total stroke of the lift table 301 is equal to the sum of the strokes of the two sub-lift tables 101, 101 '.
  • the sub-elevating tables 101, 101 ' can be actuated either synchronously or independently of each other by separate sources of force, either by a common power source.
  • lifting table 401 are a plurality of elastically deformable profile elements 405, 405 'arranged in pairs to increase the total stroke one above the other.

Rather, here are each in pairs abutting, designed as a part cylinder jacket surfaces profile elements 305, 305 'oppositely applied directly to each other, such that each of the lower profile element 405' downwardly open and the upper profile element 405 is open at the top.
  • this construction is such that by applying force to the actuating plates 422, 423, the outer longitudinal edges of the profile elements 405, 405 'are guided inwardly, thereby deforming the profile elements 405, 405' and their respective apex line a greater distance from the adjacent one Substructure 402 or upper structure 403 receives.
  • connecting structure 504 consists of a plurality of tubular, parallel to each other and abutting arranged hose-like profile elements 505.
  • Each of these profile elements 505 can be understood as integrally formed of two shell-shaped profile elements, such as she in the FIGS. 1 to 3 are shown.
  • the elastic profile elements 505 In the "retracted" state of the lifting table 501, as he in the FIGS. 5a and 5b is shown, the elastic profile elements 505 have a substantially elliptical cross-section, wherein the longer major axis is arranged horizontally, ie parallel to the substructure 502 and the upper structure 503. Along the apex lines, which are assigned to the short ellipse axes, in turn extend rib-like projections 514, 514 ', on which in each case the substructure 502 and the upper structure 503 is applied.

  • the tubular profile elements 505 again have an elliptical cross-section, after they have passed through an intermediate state in which the cross-section was approximately circular.
  • the longer ellipse axis of the cross-section of the profile elements 505 is vertical and the shorter ellipse axis is horizontal.
  • the end faces of the tubular profile elements 505 are open, so that the air trapped in its interior can escape during the deformation. in principle However, it is also possible to close these end faces, which has an influence on the "stiffness" and the carrying capacity of the profile elements 505. Possibly. it is also possible to make the pressure of the gas, for example the air, within the closed profile elements 505 adjustable. However, this adjustable pressure is not to be confused with the pressure, which serves for example for inflating a bellows-like lifting device. In the present invention, during the actual operation of the lift table, the trapped amount of gas is not changed by the supply or discharge of gas; the lifting movement takes place exclusively due to the deformation of the profile elements by a force acting in the lateral direction.

  • the sub-profiles 705 have a substantially roof shape with two approximately flat legs, which form an angle at a "roof ridge". Since the lower joints between adjacent sub-profiles 705 have the same geometry as the above-mentioned "ridge" of the sub-profiles 705, the distinction in sub-profiles is somewhat arbitrary;
