Description

The invention relates to a lifting platform, in particular for Motor vehicles according to the preamble of claim 1 and a Method of making the lift.

Lifting platforms have so far been provided with supporting columns that for example by welding together accordingly strong steel sheets. To the high Requirements of a lifting platform, for example for lifting Such a support column must correspond to motor vehicles have a certain stability. This is done either high material expenditure or by appropriate shaping achieved. Even with a corresponding profiling of A corresponding expense arises in the support column Manufacturing, especially when welding the steel sheets or profiles. In addition, it is still a big one Material expenditure necessary.

The object of the invention is therefore a lifting platform to propose a production with a greatly reduced Effort and thus reduced costs.  

This task is based on the aforementioned state of the Technology by the characterizing features of claim 1 solved.

By the measures mentioned in the subclaims advantageous embodiments and developments of the invention possible.

Accordingly, we have a lifting platform according to the invention with a Support column provided, which comprises a shaped body, the at least partially made of flowable, curable material consists.

Through the use of flowable, curable material In addition to the cost advantage, a shape is possible that was previously not feasible. The cross sections can circular, oval, star-shaped or as any polygon be trained.

In this way, for example, a lifting platform can be used manufacture a support column, which is essentially made of concrete consists. Flowable materials, such as concrete or Concrete can be combined with special supplements be considerably less expensive than the one previously used comparatively thick-walled steel.

The flowable material can, for example, by pouring, Spin or extrude are processed. Especially Concrete can be processed using these processes.

A is preferably used as the material for casting the support column waterproof special concrete used. There are now Special concrete that is not only waterproof, but with smooth and structurable surface hardens. At The support column can be used with such a special concrete can be used without additional remuneration for the outside.  

In a preferred development of this embodiment a colored concrete is used.

In another advantageous embodiment of the invention is also an at least partially the outside of the Support pillar-forming shell used with the curable, pourable material is filled. Leaves through this envelope on the one hand the appearance of the support column is positive influence, on the other hand, the technical Properties, for example the sliding ability of the Surface to be improved accordingly.

In particular, in a version without an outer shell, depending on the application, be advantageous Guide elements, such as slide rails or the like, in the pouring flowable material. On these guide elements the lifting unit mentioned can then be guided.

Preferably, a support column according to the invention Lift essentially guide means parallel to the axis for integrated a lifting device. Through such The support column is lightweight with a lifting unit to provide.

The guide means advantageously comprise at least a guide groove formed in the support column. In a such guide groove can be corresponding sliding or Rolling elements of a lifting unit reliably along the axis the support column.

In a particular embodiment of the invention, the Shell are composed of sections. This offers For example, the ability to cover the case in one Area of application or shape of the support column not visible Area to manufacture from a cheaper material. Furthermore, a composite shell made of different  Materials also desired optical effects on the Effect surface of a support column according to the invention. Each Production is simplified according to the shape of the support column an envelope according to the invention by assembling various sections also considerably.

A support column according to the invention can consist of different Covering with a covering material. The Covering material can, for example, for optical reasons Impression or also to improve the Surface properties, for example the Sliding properties, etc. are attached. Such one Covering material can be glued and / or jammed, for example or attached in any other way.

In a further special embodiment variant of the Invention, the shell is at least partially from one preformed, dimensionally stable material. This Design variant has the advantage in production that no external shaping tools after completion the cover are needed. The inherently stable shell, preferably from a metal sheet of appropriate wall thickness and if necessary with appropriate stiffening elements, only needs to be filled with the filling material, For example, concrete can be backfilled, which Stiffness of the support column thus formed increases.

In a special embodiment of the invention is for the outer wall of the support column is an extruded profile used. Such an extruded profile, for example made of anodized aluminum offers the advantage of a cheap one Manufacturing with a large selection of shapes for the Profile cross section. Especially when using Extruded profiles, it is an advantage over the Material of the extruded profile harder material on the Surface. For example, the  Use of an extruded aluminum profile and one Stainless steel covering material.

This manufacturing process can be further developed by the entire support column in the longitudinal direction in individual Extruded profiles is divided, which is only during production the support column are assembled and cast.

Such individual segments one in longitudinal and / or Transverse direction separate sheath, especially in the form of individual extrusion profiles are in a special advantageous embodiment with the aid of locking means Connection of individual segments connected. Such rest or Snap locks can be used, for example, during extrusion are molded into the individual segments and make manufacturing considerably easier.

In a further development of the invention, additional Sealant for individual fillers to be filled Filling areas of the support column are provided. This is particularly so then advantageous if the inner or outer shell of the Support column is interrupted for manufacturing reasons, such as when using multiple Extruded profiles can be the case.

In another advantageous embodiment, the Outside of the support column at least partially forming shell at least in part by not being independent dimensionally stable film formed. In this variant comes for the rigidity and thus the resilience of the Support column to the filling material even more important than in the aforementioned embodiment. On the other hand the cost of materials or costs is reduced to procure the necessary material in this Embodiment enormous.  

In a special version of the production of a Lifting platform according to the invention is the shell of the support column in arranged in a manufacturing mold and designed so that when filling with the hardenable filling material and / or the hardening of the filling material to form a Form-fit with the manufacturing mold at least partially is deformable.

To manufacture the support column or the shaped body, the deformable casing first introduced into the mold and then filled in the curable filling material. By the filling material is form-fitting to the Inner wall of the mold pressed so that there is a smooth Outer wall of the molded body in the area of the shell results. The Stability of the molded body is after the curing of the Filling material guaranteed by the filling material.

In addition to the cost advantage in production, there are new ones Possibilities in the optical design of the support column. This support column can be shaped with any design and yet a supporting function due to the design or the material selection. Because of the prefabrication in an appropriate form can be almost any shape for a support column. It also protects Outer skin the appropriate support pillar from corrosion, since that Penetration of moisture is prevented.

Furthermore, an envelope according to the invention is one Shaped body feasible a sliding surface that for example to guide a lift truck for the lift is usable.

In a particularly advantageous embodiment of the Invention is the filling of curable filling material before the curing additionally z. B. by shaking or pumping  condensed. This increases the shape accuracy, Stability and load capacity of the support column.

A prestressed column is preferably used Reinforcement provided. Especially with continuous Reinforcement that is pre-stressed results to a certain extent, a prestressed concrete molding, possibly with a Outer skin as above Through such reinforcements, possibly in Connection with a tension can be the stability and Resilience and the material utilization of the molded body significantly increase, resulting in less expensive production becomes possible.

The prestressed reinforcement parts can, for example, in Form of tension rods, tension wires or tension cables, e.g. B. made of steel or the like. The preload offers especially with concrete the advantage known from prestressed concrete, that it remains stable and does not tear.

In a further embodiment of the invention, the o.a. Clamping elements only after pouring out and hardening of the Filling material introduced. Suitable passages are used for this intended. These passages can, for example, in one Extruded profile in the form of through tubes. After pouring and curing the column is on a Base plate attached, which is connected to the clamping elements is. For example, tie rods on the base plate screwed or otherwise anchored. Subsequently can the support column by placing a cover plate and Tightening with the help of those that penetrate the support column Clamping elements can be clamped.

With the help of such Reinforcement parts the edge elements with the molded body connected. The connection of the edge elements, for example a floor or cover plate can be, for example  through continuous reinforcement parts as mentioned above happen.

By choosing the material or the shape of both Shaped body as well as the reinforcement or the filler can support columns with almost any mechanical Create properties.

In a special embodiment, a Bottom plate provided on the floor or the foundation of a Building is attachable. In this way there is a firm position of the support column on the ground, so that bending moments exerted on the support column under load, reliably in the floor or foundation of the building be derived. Especially in this embodiment it is advantageous if the inserts for stabilization, for example reinforcing steel, is continuously formed, because this greatly improves the load-bearing capacity of the support column becomes.

In an advantageous embodiment of a support column the outer skin of the molded body as a sliding surface trained and at the same time a sliding guide, for example in Form of a guide groove in the support column during manufacture molded. Inside such a guide groove preferably a lifting unit, for example in the form of a Pallet truck, arranged. This pallet truck is preferably about additional sliding elements mounted on the groove wall and over a drive unit, for example a spindle drive, height adjustable. The drive spindle also finds prefers space inside the molded in the support column Guide groove.

The casing is used to produce a lubricious surface wholly or in part preferably in the form of a film or Sheets made of steel, especially stainless steel. On  Such a smooth steel surface can easily be Pallet trucks are slidably stored. However, would be conceivable also outer shells that are made entirely or partially from others Materials, e.g. B. made of aluminum, gold, platinum, titanium, etc. are made.

To manufacture the support column according to the invention is in a particular embodiment uses a manufacturing mold that comprises a shrinkable molding compound. Here comes into question for example a cast resin that a certain Has thermal expansion. Will a during production such temperature-dependent molding compound heated and then cooled, such a manufacturing form can be due the shrinkage easier when cooling.

In a special development of the invention Production form provided with a tensionable outer wall. A metal one, for example, would be conceivable here shrinkable molding compound adjoining outer wall with a to provide a small clamping gap, which advantageously also is incorporated into the molding compound. By contracting this gap then becomes the outer wall of the manufacturing mold tense.

Preferably, in such a manufacturing form inner mold core, for example in the form of a tube intended. Such a mandrel can, for example a bracket for handling the manufacturing mold attached will. In a development of the invention, it allows Introduce heating medium inside the production mold. In For example, heating elements come into question here with media tours z. B. water pipes inside the Mold core with which the molding compound, which is within the Support column is located, can be heated.  

In a development of the manufacturing mold according to the invention a separation layer between the molding compound in different filling areas. Hereby a certain shrinkage behavior can be achieved when cooling.

Fig. 13 shows a cross section through a support column according to the invention during manufacture with a special manufacturing form.

In Fig. 1, a support column 1 of the invention is shown in which a shaped body 3 is constructed on a bottom plate 2. The molded body 3 shows a laterally open C-profile. It consists of a thin shell 4 , as shown by the solid border line. The sleeve 4 extends around the entire molded body, ie thus also on the side 6 facing the inner region 5 of the molded body designed as a C-profile. The space 7 of the molded body 3 between the outer side 8 and the inner side 6 of the sleeve 4 is hardenable Filling material, for example concrete or fiber-reinforced polymer concrete, filled. The shell 4 is selected with respect to its material so that a lubricious, corrosion-free surface forms on the inside 6 of the molded body 3 .

In the inner region 5 of the shaped body 3 constructed as a C-profile, a lifting truck 9 is arranged, which in the present exemplary embodiment is designed as a tubular section. The trolley 9 is mounted in a height displaceable via sliding elements 10 a / b / c in the group formed by the interior 5 of the shaped body 3 guide groove. 5 A spindle nut 11 is attached to the inside of the lifting truck 9 . Approximately at the level of the spindle nut 11 there is a load arm receptacle 12 protruding from the guide groove 5 . The load arm receptacle 12 is slidably supported on the opening edges 14 a / b of the guide groove 5 with two further sliding elements 13 a / b.

All sliding elements 10 a / b / c or 13 a / b are fastened via pins 15 a / b / c or 16 a / b in corresponding bores on the lifting truck 9 or the load arm receptacle 12 .

The load arm receptacle 12 comprises two bores 17 , 18 , to which support arms, not shown, of a lifting platform for motor vehicles can be fastened by means of pivot bolts.

The base plate 2 is provided with holes 19 , by means of which it can be screwed to the floor of a workshop.

The longitudinal section according to FIG. 2 shows that in addition to the upper slide members 10, b a, corresponding lower sliding elements 20 c on the lift truck 9 are attached to an event occurring on the lift truck overturning moment 9 trap.

Furthermore, it can be seen in Fig. 2 that a spindle 21 is attached to a ceiling plate 23 via a spindle bearing 22 . A drive motor 24 is attached to the top of the ceiling plate 23 . Furthermore, it can be seen that stiffening rods 25 as reinforcement completely penetrate the molded body 3 and are fastened to the base plate 2 and the cover plate 23 . For this purpose, the base plate 2 has threaded bores 26 . The stiffening bars 25 by set in the ceiling plate 23 holes 27 and are screwed at the top with clamping nuts 28th

The support column shown is, for example, as follows manufactured.  

First, a base plate with tie rods 25 is attached to a manufacturing mold. The production mold is lined with the casing 4 and then filled with filler material, for example concrete. After filling, the ceiling plate 23 is put on and tightened with the clamping nuts 28 . Clamping the ceiling plate 23 results in a compression of the filling material in the filling space 7 inside the casing 4 . The compression and the tension rods 25 result in an enormous stability of the support column 1 .

After installation of the lifting truck 9 with its drive 24 , 22 , 21 , the support column 1 can be used for a lifting platform, for example in a motor vehicle workshop.

The sliding elements 13 a / b prevent the lifting truck 9 from rotating inside the molded body 3 . These sliding elements 13 a / b could possibly be saved by shaping the shaped body 3 with a different cross section, for example an elliptical cross section, so that the lifting carriage 3 is already secured against twisting by the mounting on sliding elements 10 a / b / c.

The embodiment according to Fig. 4 substantially corresponds to the recommended type molded body, wherein now, however, the inner side 6 is arranged eccentric to the outside 8 with substantially circle-segment-like cross section of the inside 6 and the outside 8. This results in a wall reinforcement in the area 38 in which, for example when used in a support column of a lifting platform as mentioned above, the greatest bending moments can act, so that there is increased stability in this area 38 .

The two locations 80 a / b marked in FIG. 5 indicate seams at which the casing 4 is composed of two sections of different material. The outer area 8 and the parts 81 a / b of the inner area 6 can, for example, be made entirely of stainless steel. The remaining part of the inner region 6 is preferably made of a cheaper material, for example galvanized steel. With this design, the manufacturing costs of the casing 4 can be reduced. All surfaces visible from the outside are made of stainless steel, which results in a correspondingly positive visual impression, while the non-visible areas of the shell 4 can be produced without any problems from the cheaper material without impairing the optical impression of the molded body.

Fig. 6 shows an example of how the interface of an envelope 4 of a shaped body 3 according to the invention can be closed. At the interface 30 , where the casing 4 meets on both sides, the casing 4 is provided with bends 31 , 32 . The bevels 31 , 32 are attached so that they point into the interior 7 of the molded body 3 and are therefore cast in after filling with filler material. To close the casing 4 , a counter profile 33 is pushed over the folds 31 , 32 . This results in a cavity 34 , which can optionally be filled with a sealing compound 35 , for example silicone rubber. The interface 30 is thus tightly closed according to the embodiment of FIG. 5. On the outside of the molded body 3 , the seam 30 is only visible through a small chamfer. This interface can also be arranged inside the guide groove 5 so that it is hardly visible from the outside.

Instead of the silicone rubber, an adhesive can also be used as the sealing compound 35 , which glues the folds 31 , 32 to the counter profile 33 .

The support column 101 according to FIGS. 7 and 8 comprises an inner casing 102 and an outer casing 103 , the space 104 between which is poured with concrete. In the intermediate space 104 tension rods 105 are arranged, which are screwed on the bottom into a base plate 106 or z. B. are inserted in another version by means of a cone.

A support tube 107 of a tensioning bracket 108 is inserted into the interior of the support column 101 and is supported on the base plate 106 . A clamping flange 109 with circumferential through bores 110 is attached to the support tube 107 . The bores 110 are penetrated by the tension rods 105 . The end regions 111 of the tension rods 105 have an external thread 112 onto which tension nuts 113 are to be screwed.

The support column 101 is manufactured in such a way that the wall 114 is built up on the base plate 106 and the tension rods 105 are inserted. The clamping block 108 is inserted in the middle and then the clamping rods 105 are prestressed by tightening the clamping nuts 113 . The wall 114 can now be poured with concrete or other hardenable filler material.

For illustration purposes, the gap 116 between the inner wall 102 and the support tube 107 is larger in FIG. 7 than is actually shown. It enables the tensioning bracket 108 to be easily removed after the support column 101 has been completed .

As shown in Fig. 9, the wall 114 can, for example, from an extruded profile 117 , z. B. consist of anodized aluminum. Such an extruded profile 117 , in the present case with three stabilizing transverse webs 118, can be divided into several parts in the longitudinal direction, as indicated in FIG. 12. A segment-like configuration of the wall 114 is thus conceivable not only in the transverse direction, as explained with reference to FIG. 7, but also in the longitudinal direction. In both cases, the wall 114 is joined together during manufacture and held by corresponding connection points.

In all of the above-described exemplary embodiments, the clamping elements 105 described are advantageously attached, as shown in FIG. 8.

The extruded profiles described can not only from Aluminum, but from all possible pressable Alloys are made.

The embodiment according to FIG. 10 shows an extruded profile 123 , the transverse webs 124 of which are provided with receptacles 125 for the tensioning elements 105 .

Since the receptacles 125 are continuously closed in a tubular shape and no filler material can penetrate them, the clamping elements 105 can also be introduced and braced after pouring out and curing. This subsequent bracing is also possible, for example, in the case of an extruded molded body without a casing, provided the passages for the tensioning elements are molded in during extrusion.

The embodiment according to FIG. 11 essentially corresponds to the embodiment according to FIG. 7. In a departure from this, the foot parts 134 of the tension rods 105 are conically shaped, for example upset. As a result of this shape, they are fixed on the base plate, which has a corresponding conical bore 135 , and can be inserted through the base plate 106 from below.

In the illustration according to FIG. 12, two segments 137, 138 of the support column 101 according to the invention are formed as extruded sections. To connect the two segments 137 , 138 , the extruded profile 137 is provided with a thickening 139 in the area of the outer casing 103 . The extruded profile 138 is in turn provided with a groove 140 which is to be positively applied to the thickening 139 . In the area of the inner casing 102 , the segment 138 is provided with a latching lug 141 which has a run-up slope 142 . The extruded profile 137 is in turn provided with a locking shoulder 143 following an inclined sliding surface 144 . In the space between the sliding surface 144 and the locking lug 141 is a sealing cord 145 , z. B. made of rubber.

When manufacturing the support column 101 according to the invention, the two segments are first joined together with the thickening 139 or the groove 140 and the sealing cord 145 is inserted. By pivoting towards each other in the direction of the arrows S of the opposite ends of the segments 137 , 138 , the run-up slope 142 is pushed along the sliding surface 144 until the latching lug 141 engages behind the latching shoulder 143 . The cover 102 , 103 for a support column 101 according to the invention is thus finished.

Then, according to one of the above-described embodiments, the tension rods 105 are introduced and the filling material 146 is filled in. The sealing cord 145 prevents filling material 146 from getting into the interior 147 , which is undesirable for various reasons.

Fig. 13 shows in cross section a manufacturing mold 147 is manufactured in which a support column 101. The production mold 147 consists of a cylindrical outer wall 148 and a likewise cylindrical inner core 149 . The space between the outer shell 103 of the support column 101 and the outer wall 148 and between the inner shell 102 of the support column 101 and the inner core 149 is filled with a molding compound 150 , for example with hardened casting resin 150 . A separating layer 151 separates the inner region 152 from the outer region 153 in the region of the through opening 154 . A transport flange 155 is fastened, for example welded, to both the inner core 149 and the outer wall 148 .

The outer wall 148 also has fastening elements 161 , for example for a vibrator and a clamping gap 156 , which continues through the molding compound 150 to the outer shell 103 of the support column 101 . Clamping tabs 157 serve to clamp the production mold 147 .

A heating element 159 is arranged in the interior of the inner core 149 and is surrounded by a heating medium 60 .

The manufacture of a support column according to the invention with the aid of a manufacturing mold 147 takes place as follows. First, the sheath 102 , 103 of the support column 101 is introduced into the interior of the production mold 147 , the molding compound 150 being in the cooled state and the clamping gap 156 being opened, that is to say the clamping tabs 157 , 158 are not clamped to one another.

The tensioning rods 105 are then introduced by one of the methods mentioned above and, if necessary, prestressed. By tightening the clamping tabs 157 , 158 , for example with the aid of clamping screws, the mold 147 is clamped and the core 149 is heated, for example with the help of the heating element 149 and the heating medium 160 . As a result, the molding compound 150 expands inside the support column 11 and partly also in the outside area.

The tensioning and heating of the production mold 147 can take place before, during or after the filling, but before the filling material 146 has hardened. By shaking the fastening elements 161 , for example, compaction of the filling material 146 , for example of concrete, can be achieved.

After the filling material 146 has hardened , the heating element 159 is switched off, so that the molding compound 150 can cool down and shrink. The separating layer 151 ensures that the shrinking process does not lead to compression in the area of the through opening 154 , but that the inner area 152 shrinks separately from the outer area 153 .

The heating device 159 , 160 not only provides for a desired expansion of the molding compound 150 , but also for a faster curing of the filling material 146 in the interior of the support column 101 .

After loosening the clamping tabs 157 , 158 and cooling the molding compound 150 , the mold 147 can now be pulled off the finished support column 101 by axial displacement. The transport flange 155 is advantageous for this.
