Abstract

Disclosed is a rising platform, specially for a motor vehicle, which can be economically produced with little effort. According to the invention, this is done in that at least a bearing column (1) comprises a shaped body (3) which consists at least partially of a flowable, hardenable material.

Description

The invention relates to a lifting platform for motor vehicles the preamble of claim 1 and a method for Manufacture of the lift.

US 4,251,993 shows a boat lift in which a lifting cylinder is embedded in the ground below the water surface. This lifting cylinder is in a special embodiment double-walled and in the space with concrete filled. It is a so-called Underfloor lift, in which the load is axially in the form of a Piston rod is guided in the lifting cylinder. By the axial Loading of this lifting cylinder and the additional intake there are no significant bending moments on the floor Lift cylinder during operation.

The document US 5,522,661 again shows a boat lift, in which a horizontally arranged support frame on four Corner points in concrete support columns is guided over rollers. The The support frame is connected via cables that are at the top of the Support columns are deflected accordingly, raised. Through the Use of the support frame in connection with the suspension There are also pull ropes at all four corners of the support frame here no noteworthy bending moments in the support columns. By picking up the load on the pulling ropes will guide the Support frame, d. H. the leadership roles as well as the corresponding Groove in the support columns hardly loaded.

In contrast, so-called above-ground lifts have been used so far Support columns provided, for example, by Welding correspondingly strong steel sheets together can be produced (e.g. DE 3 034 907 A1). A is usually placed in the support columns Pallet truck guided, on which a load arm is pivotally arranged. The lift usually has two such columns each have two swiveling load arms. The load arms are often telescopic at the same time, so that the point of contact can be chosen arbitrarily below a motor vehicle.

Due to the resulting length of the load arm there are significant tipping moments on the pallet truck that act as bending moments must be absorbed by the support column. Therefore, in order to the high requirements of a lifting platform for lifting Motor vehicles to correspond to such a support column as well the guidance and storage of the pallet truck a certain stability exhibit. This is either due to the high cost of materials or achieved by appropriate shaping. Even with one appropriate profile of the support column is created corresponding effort in production, especially in Welding the steel sheets or profiles. In addition, how before a large amount of material necessary.

The object of the invention is therefore to provide a motor vehicle lift 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. In particular 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 the case of a design without an outer casing, it can 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. ever 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 compacted. 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. By 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.

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 used, among other things 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 formed. 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.

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 casting 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 braced.

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 become. 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.

In a particularly advantageous embodiment, a or several transport flanges on the inner mold core and / or attached to the outer wall. Thus a transport is the Manufacturing mold possible without damaging the molding compound. Furthermore, additional fasteners are preferred for further processing devices, e.g. B. for a vibrator on the manufacturing form, especially on the outer wall intended.

The sees a particularly advantageous manufacturing process Use of a clamp, by means of which the Reinforcement parts, for example reinforcement rods or Reinforcement ropes can be pre-tensioned. The function of the Clamps can e.g. B. also in the above manufacturing mold to get integrated.

Such a clamp advantageously has one Vertical section, for example in the form of a support tube, on, which is inserted inside the support column to be manufactured becomes. This vertical section is supported on the base plate the support column to be manufactured. At the top of the Vertical sections are corresponding fasteners provided for tensioning the reinforcement parts. such Fasteners are in a simple Embodiment given by a horizontal flange, the circumferential holes for receiving the reinforcement parts, for example the reinforcement rods, ropes or wires having.

The reinforcement parts are used in the manufacture of the support column first attached to the base plate, for example screwed. After inserting the clamp into the inside of the The outer shell of the support column to be manufactured penetrate the Reinforcement parts, the holes mentioned in the cross flange. By clamping nuts, which are screwed onto the reinforcement parts can now be put under tension. The reinforcement can also otherwise, e.g. B. hydraulic be excited.

In an advantageous further development of this Manufacturing process, the clamp is designed so that he at least partially as the core for the support column during can serve for pouring out. Through the clamp or its The vertical section is not just the reinforcement tense, but at least partially the inner wall centered.

He consists of a thin shell 4, as through the solid Border line shown. The shell 4 extends around the entire molded body, d. H. thus also on the Inner area 5 of the shaped body designed as a C-profile facing side 6. The space 7 of the molded body 3 between the outside 8 and the inside 6 of the casing 4 is with hardenable filling material, such as concrete or fiber-reinforced polymer concrete, filled. The shell 4 is like this selected with regard to their material so that a lubricious, corrosion-free surface on the inside 6 of the molded body 3 forms.

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 Embodiment is designed as a pipe section. The Pallet truck 9 is in the by the sliding elements 10a / b / c Inner region 5 of the molded body 3 formed guide groove 5 height adjustable. Inside the truck 9 is a spindle nut 11 attached. At about the level of Spindle nut 11 is located sigh outside one of the Guide groove 5 protruding load arm receptacle 12. The Load arm receptacle 12 is provided with two further sliding elements 13a / b sliding on the opening edges 14a / b of the guide groove 5 supported.

All sliding elements 10a / b / c or 13a / b are via pins 15a / b / c or 16a / b in corresponding holes on the pallet truck 9 or the load arm holder 12 attached.

The load arm receptacle 12 comprises two bores 17, 18 on 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 can be screwed to the floor of a workshop.

The longitudinal section of FIG. 2 shows that in addition to the upper Sliding elements 10a, b, c corresponding lower sliding elements 20 are attached to the pallet truck 9 to a on the pallet truck 9th intercept occurring tilting moment.

Furthermore, it can be seen in Fig. 2 that a spindle 21 over a spindle bearing 22 is attached to a ceiling plate 23. On the top of the ceiling plate 23 is a drive motor 24 attached. It can also be seen that Stiffening rods 25 as a reinforcement for the molded body 3 fully enforce and on the base plate 2 and the Ceiling plate 23 are attached. The base plate 2 has for this purpose threaded holes 26. The stiffening rods 25 push through 23 holes in the ceiling plate and are on screwed on the top with clamping nuts 28.

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

First, a base plate is attached to a manufacturing mold Tension rods 25 attached. The production form is with the Sleeve 4 lined and then with filler material, for example concrete. After filling the Cover plate 23 placed and with the clamping nuts 28th dressed. By stretching the ceiling plate 23 results a compression of the filling material in the filling space 7 inside the shell 4. By the compression and the tie rods 25th there is an enormous stability of the support column 1.

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

4 corresponds essentially to that prescribed molded body, but now with im essential cross-section-like cross section of the inside 6 and the outside 8, the inside 6 eccentric Outside 8 is arranged. This results in a Wall reinforcement in the area 38 in which, for example at use in a support column of a lift as above can attack the greatest bending moments, so that increased stability is provided in this area 38.

Mark the two positions 80a / b marked in FIG. 5 Seams at which the shell 4 consists of two parts different material is composed. The Outside area 8 and parts 81a / b of inside area 6 can consist of stainless steel, for example become. The remaining part of the inner region 6 is preferred made of a cheaper material, for example galvanized Made of steel. With this design, the Reduce the manufacturing costs of the casing 4. All from the outside visible surfaces are made of stainless steel there is a correspondingly positive visual impression, while the invisible areas of the sheath 4 easily from the cheaper material without affecting the optical impression of the molded body can be produced can.

6 shows an example of how the seam of a casing 4 of a molded body 3 according to the invention can be closed can. At the interface 30, where the sleeve 4 on both sides meets each other, the shell 4 with bevels 31, 32nd Mistake. The bevels 31, 32 are attached so that point them into the interior 7 of the molded body 3 and thus are filled with filling material after filling. To the Closing the shell 4 is a counter profile 33 on the Bends 31, 32 pushed over. This results in a Cavity 34, optionally with a sealing compound 35, For example, silicone rubber can be filled. The Interface 30 is thus according to the embodiment of FIG. 5 tightly closed. On the outside of the molded body 3 is the seam 30 is only visible through a small chamfer. This interface can also be inside the guide groove 5 be arranged so that it is hardly visible from the outside.

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

The support column 101 according to FIGS. 7 and 8 comprises one Inner shell 102 and an outer shell 103, the space between them 104 is poured with concrete. In the space 104 are Tensioning rods 105 arranged, the bottom in a Bottom plate 106 screwed or z. B. in another Execution are inserted by means of a cone.

Inside the support column 101 is a support tube 107 Clamping jack 108 introduced, which is on the bottom plate 106th supported. A clamping flange 109 is also on the support tube 107 circumferential through holes 110 attached. The holes 110 are penetrated by the tie rods 105. The End regions 111 of the tension rods 105 have an external thread 112 to be screwed onto the clamping nuts 113.

The support column 101 is manufactured in such a way that the wall 114 built on the bottom plate 106 and the Tie rods 105 are inserted. The clamp 108 is in inserted in the middle and then the tie rods 105 preloaded by tightening the clamping nuts 113. Now that can Wall 114 with concrete or other curable Filling material to be poured out.

The gap 116 between the inner wall 102 and the support tube 107 is larger than that in FIG. 7 for illustration Represented reality. It enables easy removal the trestle 108 after completion of the support column 101.

As shown in FIG. 9, the wall 114 for example from an extruded profile 117, for. B. from anodized aluminum. Such a thing Extruded profile 117, in the present case with three stabilizing ones Crossbars 118 can be divided into several parts in the longitudinal direction be divided, as indicated in FIG. 12. So is one segment-like formation of the wall 114 not only in Transverse direction, as explained with reference to FIG. 7, but also in the longitudinal direction conceivable. In both cases the wall 114 assembled during production and by appropriate Connections held.

In all the above-described embodiments advantageously as shown in Fig. 8, the described clamping elements 105 attached.

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

The embodiment according to FIG. 10 essentially corresponds 7, the base parts 134 differ of the tie rods 105 conical, for example upset. With this design, they are on the Base plate that has a corresponding conical bore 135 has, fixed, from below through the Base plate 106 can be inserted.

11 shows two segments 137, 138 the support column 101 according to the invention as extruded profiles educated. To connect the two segments 137, 138 is the extruded profile 137 in the area of the outer casing 103 provided with a thickening 139. The extruded profile 138 in turn is provided with a groove 140 which is form-fitting the thickening 139 is to be created. In the area of the inner shell 102, segment 138 is provided with a detent 141, which has a run-up slope 142. The extruded profile 137 in turn is with a locking shoulder 143 following one provided oblique sliding surface 144. In the space is between the sliding surface 144 and the locking lug 141 Sealing cord 145, e.g. B. made of rubber.

In the manufacture of the support column 101 according to the invention the two segments first with the thickening 139 or the Groove 140 joined together and the sealing cord 145 inserted. By pivoting against each other in the direction of arrows S the opposite ends of the segments 137, 138 is the Sloping slope 142 is pushed along the sliding surface 144 until the locking lug 141 engages behind the locking shoulder 143. Consequently is the sheath 102, 103 for a support column according to the invention 101 done.

Then according to one of the above Embodiments introduced the tie rods 105 and that Filling material 146 filled. The sealing cord 145 prevents here that filling material 146 get into the interior 147 can do what is undesirable for various reasons.

12 shows in cross section a production mold 147 in which a support column 101 is manufactured. The production form 147 consists of a cylindrical outer wall 148 and a also 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 made with a molding compound 150, for example with hardened casting resin 150, filled. A separation layer 151 separates the inner area 152 from the outer area 153 in the area the through opening 154. Both on the inner core 149 and a transport flange 155 is fastened to the outer wall 148, for example welded.

The outer wall 148 also has fastening elements 161, for example for a vibrator and a clamping gap 156 that extends through the molding compound 150 to the outer casing 103 the support column 101 continues. Clamping tabs 157 are used for Clamping the production mold 147.

A heating element 159 is surrounded inside the inner core 149 arranged by a heating medium 60.

The production of a support column according to the invention with the help a manufacturing mold 147 takes place as follows. First is the shell 102, 103 of the support column 101 inside the Manufacturing mold 147 introduced, the molding compound 150 itself is in the cooled state and the clamping gap 156 open, that is, the clamping tabs 157, 158 are not are tense to each other.

Then the tie rods 105 according to one of the above introduced procedures and if necessary biased. By tightening the tensioning straps 157, 158, for example with the help of clamping screws, the shape 147 braced and the core 149 with the help of the heating element 149 and the heating medium 160, for example water heated. As a result, the molding compound 150 expands inside the support column 11 and partly also in the outside area.

Tensioning and heating the production mold 147 can during or after filling, however, before the hardening of the Fill material 146 take place. By shaking, for example on the fasteners 161, compression of the Filling material 146, for example of concrete can be achieved.

After the filling material 146 has hardened, the heating element 159 turned off so that the molding compound 150 can cool and shrinking. Through the separating layer 151 ensures that the shrinking process does not become a Pressing in the area of the passage opening 154, but that the inner area 152 is separate from the outer area 153 shrinks.

The heater 159, 160 not only provides one desired expansion of the molding compound 150, but at the same time for faster hardening of the filler 146 inside the support column 101.

After loosening the tension tabs 157, 158 and cooling the Molding compound 150 can now form 147 by axial displacement are deducted from the finished support column 101. This is the transport flange 155 is an advantage.
