Description

[0001] The present invention relates to a transfer system and a transfer method for a lifting platform and a carrying device (in particular a vehicle skid).

[0002] A vehicle lift can be used, for example, to raise a vehicle to access its undercarriage. The vehicle is lifted using the lift's arms. If a vehicle is currently on the lift for repair, it cannot be used for a second vehicle until the first repair is complete. Should the repair be delayed, the lift will remain occupied by the first vehicle for that period. To extend the lift's usability, the first vehicle can be moved from the lift onto a support frame to remove it from the platform. This allows the lift to be used for the second vehicle.

[0003] A detachable lifting platform mount is known, for example, from DE 10 2017 100803 A1. A motor vehicle is lifted onto a support device or a two-column lifting platform via four mounts. Two sliding crossbeams are provided on the vehicle skid, each with mounting points at its respective end for receiving the motor vehicle.

[0004] It is an object of the present invention to provide an improved transfer system and an improved transfer method for the optimal transfer of at least one support element. In particular, it is an object to provide a simple transfer system for the error-free and process-reliable transfer of a support element. Furthermore, it is an object to provide an improved transfer method for the simple and error-free transfer of a support element.

[0005] These tasks are solved by the characteristics of independent claims. Advantageous further developments can be found in dependent claims.

[0006] A transfer system according to the invention for transferring at least one support element can comprise a lifting platform and a movable carrying device. The lifting platform can have at least one pivotable arm, which may include a gripping element for receiving the support element. The carrying device can have at least one receiving area for receiving the support element. The receiving area can comprise a first rotary mount, a second rotary mount, and an end connection (end receptacle) for receiving the support element. The end connection can have a bolt that is displaceable along a longitudinal axis. The transfer system according to the invention makes it possible to provide a simple and robust, yet process-reliable and error-free transfer system. In particular, the combination of a first rotary mount and a second rotary mount for simple and process-reliable contact with the support element is proposed.Secure mounting of the support element is further ensured by the bolt, which is movable along the longitudinal axis and can preferably be inserted into an opening in the support element. Thus, according to the invention, a transfer system is proposed with which simple and precise positioning of the end connection relative to the support element is achieved, enabling a reliable and error-free transfer of the support element from the lifting platform to the carrying device and vice versa.

[0007] The movable bolt can be displaced along its longitudinal axis from a first to a second position. The bolt can be held in the first position by an elastic element. The end connection is designed to receive the support element, and the end connection incorporates the movable bolt. Because the bolt is held along its longitudinal axis by an elastic element, a simple and robust coupling of the end connection to the support element is possible. In particular, by pressing the movable bolt along its longitudinal axis against the force of the elastic element and simultaneously rotating the first and / or second rotary joint, a simple connection to the coupling point of the support element can be achieved.By appropriately rotating the first and / or second rotary mount, the movable bolt can be moved along a horizontal plane. Upon reaching the opening of the support element (in the area of ​​the coupling point of the support element), the movable bolt is pressed into the opening of the support element by the force of the elastic element. Preferably, the movable bolt thus engages in the opening of the support element. The end connection can be moved in the horizontal plane by shifting the first and second rotary mounts. The engagement of the bolt in the opening of the support element couples the support element to the end connection of the support device in the horizontal plane. For contact in the vertical direction, which is perpendicular to the horizontal plane, the support element can be placed directly onto the end connection.The weight of the support element, and especially of any object positioned on it, ensures secure contact between the support element and the end connection. This allows for a particularly robust and reliable, yet simple and process-safe transfer system.

[0008] The transfer system can include a sliding bolt with a spherical head forming a bolt end, which can be positioned along the bolt's longitudinal axis. To improve contact between the end-connection bolt and the opening of the support element, a spherical head can be provided at the bolt end, which can be inserted (at least partially) into the opening of the support element. This achieves self-centering and ensures faster and easier contact between the bolt and the opening of the support element.

[0009] The sliding bolt can have a cylindrical section that can be connected to the spherical head via a tapered section. This specific design of the sliding bolt further improves process reliability and fault tolerance, particularly by enhancing the contact between the bolt and the support element.

[0010] Advantageously, the elastic element can be a spring. Preferably, the spring is a coil spring that presses the bolt into an extended position. To transfer the support element from the lifting platform to the carrying device, the movable bolt can be pressed into a retracted position against the spring force (e.g., manually), so that when the end connection is positioned below the support element (upon reaching the downward-facing opening of the support element), the movable bolt is pressed into the opening of the support element by the spring force. This ensures precise positioning of the support element on the carrying device.

[0011] The movable bolt can be a receiving mandrel that is displaceable along the longitudinal direction of the bolt and is held in a first position (extended position) by an elastic element, which is advantageously a spring. In a second position (retracted position), the movable bolt is located in a bushing.

[0012] Advantageously, the spherical head of the bolt can have at least one hemisphere. This particularly advantageous design enables a particularly reliable and simple contact with the opening of the support element.

[0013] The bolt can protrude further from the bushing (or sleeve) in the first position than in the second position. The first position is therefore the extended position, and the second position is the retracted position of the bolt. Preferably, in the second position, the bolt (especially the head of the bolt) is completely enclosed within the bushing, allowing the end connection to be easily moved under the support element until the lower opening of the support element is reached, enabling the bolt to engage.

[0014] In the second position, the bolt can be fully inserted into the bushing, so that the spherical head or end piece of the bolt is flush with the end of the bushing. This arrangement results in a particularly easy connection between the support device and the mounting element.

[0015] The end connection can include a bushing in which the bolt is slidably mounted. To accommodate the support element on the carrying device, the bolt can be spring-loaded to move into a lower opening of the support element. The support element can rest on shoulders of the bushing. This advantageous design allows axial forces to be absorbed via the shoulders of the bushing and horizontal forces via the cylindrical surface of the bolt, which is inserted into the lower opening of the support element. In other words, when the support element is coupled to the end connection of the carrying device, the vertical forces introduced into the end connection via the support element can be absorbed by the shoulders of the bushing, and the orthogonal forces in the horizontal plane can be absorbed by the cylindrical surface of the bolt, which is inserted into the opening of the support element.This advantageous design ensures optimal force flow, enabling safe and easy contact between the carrying device and the support element and the vehicle or object placed on it.

[0016] The movable bolt can be a spring-loaded receiving mandrel, designed for insertion into an opening in the support element. Preferably, the opening in the support element is located on the underside of the support element, opposite the bearing surface of the support element on which the object to be supported, for example a motor vehicle, is placed.

[0017] The end connection can be fixed to the second rotary mount. Advantageously, the end connection is movable together with the second rotary mount, so that when the second rotary mount is adjusted or rotated, the end connection also moves. The end connection can thus be moved in a horizontal plane via the second rotary mount, preferably until it reaches the lower opening of the support element and engages or connects with the support element. Preferably, the bushing can be permanently connected to the second rotary mount (e.g., welded).

[0018] The first rotary fixture can be rotatable about a first axis of rotation, and the second rotary fixture can be rotatable about a second axis of rotation. The second rotary fixture can be mounted on / at the first rotary fixture. The end connection can be fixed to the second rotary fixture. This advantageous design allows the end connection to be positioned at any point within a defined circle in the horizontal plane by rotating the first and / or second rotary fixture. This advantageous circular path adjustment is backlash-free and robust, which is particularly beneficial for use in paint shops. Therefore, a simple, robust, and process-reliable design for the transfer system can be proposed.

[0019] The first rotary mount can rotate 360 ​​degrees around its first axis, and the second rotary mount can rotate 360 ​​degrees around its second axis. This advantageous design allows for freely adjustable displacement of the end connection within a defined circle, enabling the decoupled bolt to be positioned precisely under the corresponding mounting bore of the support element.

[0020] The first rotary mounting can be a turntable (rotary plate) rotatably mounted on a first bearing pin. The second rotary mounting can also be a turntable rotatably mounted on a second bearing pin. Both the first and second turntables are thus rotatable around their respective bearing pins, with the second turntable advantageously being fixed to the first turntable via the second bearing pin and rotating with it, preferably in the horizontal plane. This provides a simple and robust design for reliable process transfer.

[0021] The longitudinal axis of the movable bolt can advantageously be parallel to the first and / or second axis of rotation. The axis of rotation can preferably pass through the bearing bolt. Furthermore, the movable bolt can be displaceable parallel to the first and / or second axis of rotation. This design ensures the simplest and most reliable adjustment of the end connection.

[0022] The second turntable can be mounted directly on the first turntable. This advantageous design allows for simultaneous and safe adjustment of the turntables.

[0023] The second rotary disk can be rotatably mounted on the second bearing pin, and the second bearing pin can be connected to the first rotary disk and move together with it. This provides a combined movement of the first and second rotary mounts for robust and reliable positioning of the end connection or the pin and bushing.

[0024] It is particularly advantageous for the first rotary disc to be mounted eccentrically on the first bearing pin and / or for the second rotary disc to be mounted eccentrically on the second bearing pin. This eccentric mounting of the first and / or second rotary disc allows for a wider range of adjustment positions in the horizontal plane, thus ensuring a very broad adjustment range for the end fitting. In other words, the bolt and / or bushing of the end fitting can be securely positioned in the horizontal plane via the eccentrically mounted first and / or second rotary disc. Additionally, the end fitting can be fixed eccentrically to the second rotary disc.

[0025] The support device can advantageously have a frame with a multitude of receiving openings (plug-in positions) for the bearing pin of the first turntable. The first bearing pin can be positioned in a receiving opening of the frame of the support device. By providing a multitude of receiving openings for the first bearing pin, it is possible to provide a flexible support device for flexible positioning of the support element in the horizontal plane. In other words, both narrow and wide vehicles can be supported on the support device by appropriately positioning the first bearing pin in the desired receiving opening among the multitude of receiving openings.

[0026] Preferably, the carrying device has wheels and is movable. It is further advantageous if the carrying device is designed as a vehicle skid.

[0027] The frame of the support device can have several insertion positions for the first bearing bolts that support the first turntable. This allows the second turntable and the end connection to be positioned at the various insertion positions of the support device, along with the first turntable, for flexible support of vehicles or objects of varying widths.

[0028] The first and / or second swivel mount can be self-locking. This self-locking design prevents rotation under load. A friction-based self-locking mechanism is advantageous. Specifically, when the end connection is loaded, the weight of the support element and the object placed upon it (e.g., a vehicle) exerts a force on the respective swivel mount, creating a frictional connection between the contact surface and the first and / or second swivel mount. Therefore, under load, the first swivel mount can be frictionally connected to the frame of the support device (directly or indirectly), preventing further rotation. Similarly, when the end connection is loaded, the second swivel mount can be frictionally connected to the first swivel mount to prevent further rotation.

[0029] A vehicle lift is advantageous. The lift can also be an in-ground lift or a column lift.

[0030] The gripper can have a gripping opening which, in the pivoting direction of the swiveling arm, has a slot for inserting the bushing. This advantageous design makes it possible to easily contact the swiveling arm with the support element, which, for example, rests on the bushing of the end connection of the support device. The gripping opening advantageously has a diameter that is smaller than the diameter of a cylindrical section of the support element (the plate of the support element), so that the support element can be at least partially inserted / placed into the gripping opening, onto a contact side of the gripper.

[0031] Advantageously, the swiveling arm for changing the extension length can be designed as a telescopic arm. This advantageous design allows for a particularly flexible coupling of the swiveling arm of the lifting platform with the support element resting at the end connection. The gripper can have a centering device, which is preferably arranged opposite the contact side of the gripper where the support element is received. The centering device can have a centering opening with a smaller opening width than the slot of the gripper. This advantageous design makes it possible to achieve centering when coupling the gripper with the support element resting at the end connection. The centering device can have a centering opening with a smaller opening width than that of the receiving ball of the support plate.The centering device is preferably positioned concentrically to the receiving bore of the gripper. Preferably, the centering opening is also centered on the bushing.

[0032] Advantageously, a control device can be provided for controlling the lifting platform, wherein the control device can be configured such that at least one predetermined stop position of the at least one arm is provided, so that the movement of the at least one arm can be automatically stopped upon reaching the stop position. This advantageous control device makes it possible to define predetermined stop positions to prevent a collision of the arm with the support device. Therefore, when the lifting platform is operated manually, it is possible, for example, to enable automatic stopping when the arms are moving, preferably in a vertical direction and / or horizontal direction (pivot direction of the arm), thus preventing a collision. The stop position can therefore be provided to prevent a collision of the arm with the support device.This can be advantageously achieved by an additional shutdown mechanism integrated on / in the stage (limit switch, software stop, pulse generator, height measuring system, etc.). This allows for a simple and reliable system.

[0033] The lifting device can have at least four receiving areas, and the lifting platform can have at least four pivoting arms. An end connection can be provided in each receiving area. This advantageous design makes it possible, for example, to lift motor vehicles via four receiving points by appropriately contacting four support elements with the support points of the motor vehicle.

[0034] According to the invention, a vehicle skid (carrying device) for picking up an object is also proposed.

[0035] An inventive method for decoupling a support element on a lifting platform for transferring the support element to a carrying device with a transfer system can comprise the following steps for transferring the at least one support element: moving the bolt of the end connection into an opening of the support element and placing the support element on the end connection (in particular on shoulders of the socket of the end connection). The bolt can first be pressed into the socket, and by shifting the end connection below the opening of the support element, the bolt can be spring-loaded into the opening. The carrying device can then be removed (together with the transferred receiving element) from an area of ​​the lifting platform, for example, by moving the carrying device together with the receiving elements and the vehicle or object attached to it.

[0036] The lifting platform and the carrying device can advantageously be positioned relative to each other without affecting an object resting on the at least one support element, wherein the at least one support element can be placed on at least one support point.

[0037] The method for decoupling the support element can be carried out in reverse, enabling the transfer of at least one support element from the support device to the lifting platform. Advantageously, an arm of the lifting platform can be pivoted towards the end connection of the support device, so that the gripping piece encloses the bushing. The arm can then be raised vertically, ensuring that the support element rests on the contact side of the gripping piece. This releases the support element from the end connection of the support device. After the at least one arm has been moved to the appropriate height, the support device can be removed from the area of ​​the lifting platform.

[0038] Advantageous further developments of the invention are explained in more detail with reference to the described embodiments in conjunction with the drawings.

[0039] The following describes various examples of the present invention with reference to the figures, wherein identical or similar elements in the figures are designated by the same reference numerals. However, the present invention is not limited to the described examples, but further comprises modifications of features of the described examples and combinations of features of different examples within the scope of the independent claims.

[0040] Fig. Figure 1 shows a first view of the transfer system according to the invention for transferring at least one support element 3 (support plate). The support elements 3, which are in Fig. The supports shown in 1 are used, for example, to lift a motor vehicle using the support points provided by the vehicle manufacturer. The support elements 3 allow for the gentlest possible lifting of the motor vehicle.

[0041] The carrying device 2, as in Fig. The carrying device 2, as shown in Figure 1, preferably has four wheels 2g, a drawbar 2e, and a coupling 2f. The carrying device 2 thus forms a trolley that can be moved freely, for example, in a workshop. The carrying device 2 has four receiving areas, each with end connections A. These end connections A serve to directly receive the support elements 3 via the bolt A1 (end connection bolt) and the bushing A2 of the end connection A of the carrying device 2. The carrying device 2 advantageously has a relatively low overall height (preferably less than 350 mm), so that the vehicle can be easily lifted onto the support elements 3, and the center of gravity is as close to the ground as possible. This prevents the carrying device 2 from tipping over, for example, when cornering.

[0042] The support device 2 is designed as a vehicle skid. A frame 2b is proposed, which allows longitudinal adjustment of the support device 2 via telescopic beams. This longitudinal adjustment of the support device 2 via the telescopic frame 2b enables simple and efficient adjustment of the support device 2 to adapt to the load or vehicle being supported. Advantageously, the frame 2b has outer tubes with bores and an inner tube with corresponding bores. The bores in the outer tube and the inner tube inserted therein allow the frame 2b to be fixed for a specific length using bolts or screws.

[0043] In the transverse direction of the support device 2, beams 2c are proposed, which advantageously have a plurality of bores. In addition, additional bores are provided for receiving the support elements 3, as shown in Fig. Figure 1 shows that when the carrying device 2 is moved, for example through the workshop, the support elements 3 can be arranged in the additional bores so that they can always be carried along with the carrying device 2 and used when needed.

[0044] The wheels 2g of the carrying device 2 are advantageously designed as swivel wheels to facilitate movement of the carrying device 2. The carrying device 2 can be coupled to a towing vehicle via the coupling 2f, thus enabling easy movement or pulling of the carrying device 2. The swivel wheels 2g ensure optimal cornering of the carrying device 2.

[0045] The support device 2 has bearing surfaces 2d on the beam 2c. The bearing surfaces 2d are designed as bearing plates. These bearing plates have receiving openings 2a for bearing bolts. As in Fig. As shown in Figure 1, several receiving openings 2a can be provided. The receiving openings 2a can be arranged on the support plate in such a way that the position of the end connection A can be advantageously adjusted in the horizontal plane. For example, if a vehicle with a narrow width is being picked up, the end connection A can be contacted with the desired receiving opening 2a via the first and second rotary mounts D1 and D2, so that the required width for picking up the vehicle can be set. The receiving openings 2a are arranged at least along the longitudinal axis of the beam 2c to allow adjustment of the distance between two opposing end connections A.By positioning the rotary mount with its end connection A at the inner receiving opening 2a of the support device 2 (at all four receiving areas of the support device 2), a very narrow receiving width of the support device 2 can be achieved. The end connections A of the four receiving areas of the support device 2 are thus arranged as close as possible to each other (in the direction of the beam's longitudinal axis 2c).

[0046] Conversely, to accommodate a wide vehicle, the respective rotating mounts can be positioned with the end connections A on the outer mounting openings 2a of the support device 2, so that a maximum distance between the opposing end connections A of the mounting areas can be achieved.

[0047] In each of the four receiving areas of the support device 2, an end connection A with a bolt A1 (receiving mandrel) is arranged, which is slidably (recessively) received in a bushing A2. The bushing A2 is fixed to a second rotary mount D2, which is, for example, a turntable. The second rotary mount D2 is received by the first rotary mount D1 via a bearing bolt. The first rotary mount D1, in turn, is provided by a bearing bolt on a receiving opening 2a of the support surface 2d of the support device 2. The first rotary mount D1 is rotatably mounted about the first bearing bolt, which connects the first rotary mount D1 to the receiving opening 2a. The second rotary mount D2 is rotatably connected to the first rotary mount D1 via the bearing bolt. The bolt A1 is held in the extended position by a spring. Therefore, the bolt A1 protrudes from the bushing A2, so that the spherical head of the bolt A1 protrudes.By using spring-loaded, retractable mounting bolts A1 (mounting mandrels), a convenient and simple mounting of the support elements 3 can be achieved. When the end connection A contacts a support element 3, which supports the vehicle via a raised arm 4 of the lifting platform 1, the bolt A1 is compressed along its longitudinal axis and positioned under the bore of the support element 3 by rotating the swivel mounts. This allows for quick and effective contact between the support element 3 and the end connection A. Upon reaching the opening of the support element 3, the compressed bolt A1 can engage or be inserted into the opening by the spring force. This eliminates the need for time-consuming and error-prone probing via the lifting platform's control panel. The system can therefore also compensate for manufacturing tolerances and ensure consistent mounting quality.This also increases safety.

[0048] A key advantage of the vehicle skid is its adjustable length, for example, by being linearly adjustable or foldable. This allows the carrying device to be adapted to different object lengths and enables space-saving storage. For storage, the drawbar can also be removed, telescopically retracted into the vehicle skid, or folded down onto the skid. Multiple vehicle skids or carrying devices can be stacked on top of each other for space-saving storage, for example, on mounting pins.

[0049] The drawbar of the vehicle skid can be detachable and thus also used in conjunction with other vehicle skids or carrying devices. The carrying device advantageously has additional openings for further securing the object placed on it, e.g., a vehicle, an electric vehicle battery, etc.

[0050] The first rotary mount D1 can be freely positioned by repositioning it in the mounting openings 2a to accommodate vehicles of varying widths. Furthermore, the rotary mounts are eccentrically mounted. The first turntable is eccentrically mounted on a first bearing pin B1, and the second rotary mount D2 is eccentrically mounted on a second bearing pin B2. Since the second bearing pin B2 is mounted on the first rotary mount D1, the first and second rotary mounts can move together. The bolt A1 attached to the second rotary mount D2 can thus be moved to any point within a defined circle by rotating the eccentrically mounted rotary mounts D1 and D2. This allows the respective decoupled bolt A1 to be positioned precisely under the corresponding mounting bore of the corresponding support element 3 (mounting plate).This circular track adjustment is virtually backlash-free and robust, which is particularly advantageous when used in paint shops. Furthermore, the system is self-centering during bolt insertion and subsequently provides a self-locking mechanism against rotation through frictional engagement (due to the weight of the vehicle being mounted).

[0051] The in Fig. The lifting platform 1 shown in Figure 1 has four arms 4, each encompassing a gripping element 5 located at the end of the respective arm 4. The arm 4 is a swivel arm designed as a telescopic arm for longitudinal adjustment. The swiveling and length-adjustable arm 4 is therefore very flexible, enabling easy and efficient handling of the support elements 3. The in Fig. The lifting platform 1 shown in Figure 1 has a first and second column 1a. The arms 4 are mounted at respective joints 1b, with the pivoting movement of the arms 4 being controlled, for example, by a gearbox.

[0052] In Fig. Figure 2 shows a further illustration of the transfer system. The arms 4 of the lifting platform 1 are in a lower position in the area of ​​the end connections A of the support device 2. The arms 4 can be moved vertically along the longitudinal axis of the columns 1a. The particularly flat design of the support device 2 allows for the lowest possible center of gravity, thus improving its maneuverability. This increases safety when maneuvering the support device 2, especially when loaded with a vehicle. The low overall height also allows for a low clearance height and is therefore ideal for use in freight elevators. Advantageously, the support device 2 has a removable drawbar 2e.

[0053] The transfer system advantageously features a control device that defines predetermined stop positions for the lifting platform arms. Implementing these additional stops in the platform software enables fast and collision-free operation when using the support device 2 in relation to the lifting platform. This results in an efficient system with increased safety. For example, the stops can be set so that when the arms 4 move vertically along the columns 1a, the movement of the arms 4 is stopped before they reach or collide with the support device 2 positioned in the lifting platform 1, thus preventing a collision. This design also reduces the transfer time.

[0054] In Fig. Figure 3 shows a detailed view of the support device 2 and, in particular, of the receiving area of ​​the support device 2. The first rotary mount D1 is provided on the support device 2 at a receiving opening 2a. The first rotary mount D1 preferably has a disc-shaped or plate-shaped form. The first rotary mount D1 is eccentrically mounted on the first bearing bolt in the receiving opening 2a. The circular path adjustment of the receiving mandrel is achieved by the combination of the first and second rotary mounts D1 and D2, which are each eccentrically mounted on their respective bearing bolts. The receiving mandrel is fixed to the second rotary mount D2 via the bushing A2. The combination of the bolt A1 with the bushing A2 forms the end connection A, which serves for contacting and receiving the support element 3.The support element 3 is positioned at the end terminal A such that, upon receiving the support element 3, the bolt A1 is inserted into a lower opening of the support element 3, and a contact surface of the support element 3 makes contact with the shoulders of the bushing A2. The support element 3 thus rests on the bushing A2, with the bolt A1 protruding into the opening of the support element 3. The spring then presses the bolt A1 into the opening of the support element 3. During the coupling process of the support element 3 with the end terminal A, the bolt A1 can be pressed into the bushing A2, so that when the opening of the support element 3 is reached, the bolt A1 snaps into place, and the support element 3 can be quickly, easily, and securely connected to the end terminal.

[0055] In Fig. Figure 3 shows a support element 3 which is received in a gripping piece 5 of the arm 4. The gripping piece 5 has a slot 5c through which a section of the support element 3 (preferably a cylindrical section under the support plate of the support element) can be inserted into the gripping opening.

[0056] Fig. Figure 4 is a detailed view of the receiving area of ​​the support device 2. The receiving area has a first bearing pin B1, which is positioned in a receiving opening 2a of the support device 2. The first bearing pin B1 serves for the eccentric mounting of the first rotary mount D1. The first rotary mount D1 can be designed as a turntable, as shown in Fig. Figure 4 shows that this rotary table preferably has a circumferential step. This circumferential step can be in contact with the support surface 2d. Under vertical load along the longitudinal axis of the first bearing pin of the rotary table, a friction-fit anti-rotation device for the first rotary mounting D1 can be achieved.

[0057] The second bearing bolt B2 for supporting the second rotary mount D2 is connected to the rotary table of the first rotary mount D1. The second bearing bolt B2 is positioned off-center on the rotary table of the first rotary mount D1. The first bearing bolt B1 and the second bearing bolt B2 are arranged parallel to each other and also parallel to bolt A1.

[0058] The second rotary mounting D2 is eccentrically mounted on the second bearing pin B2. The second rotary mounting D2 is rotatably arranged about the longitudinal axis of the second bearing pin B2. The first rotary mounting D1 is rotatably arranged about the longitudinal axis of the first bearing pin B1. The second rotary mounting D2 is also rotatably arranged about the axis of the first bearing pin B1 by connecting (fixing) the second bearing pin B2 to the rotary table of the first rotary mounting D1. To improve the self-locking of the first rotary mounting and / or the second rotary mounting, a surface coating can advantageously be provided on the rotary table.

[0059] In one end section of the second rotary mount D2, a fixing area is provided for attaching the bushing A2. The bushing A2 serves to receive the bolt A1, which is slidable along the bolt's longitudinal axis A3. The bolt A1 is pressed into an extended position by the spring A4. The pin A5 is provided to limit the bolt's extension. The bolt A1 can be inserted into an opening in the support element 3 to limit the support element 3 in the horizontal plane. To absorb the vertical forces, the support element 3 rests on the shoulders A2b of the bushing A2. The shoulders of the bushing A2 are formed by the end faces of the bushing A2 in the direction of the extended bolt head.

[0060] The bolt A1 has a cylindrical section A1z, which transitions via a tapered section A1t into a spherical head A1k. The spherical head A1k of the bolt A1 enables efficient contact with the opening of the support element 3. The tapered section of the bolt A1 further improves contact with the opening of the support element 3, particularly in the case of rotations or tilts.

[0061] Fig. Figure 5 is a diagram illustrating the circular path adjustment via the first and second rotary mounts D1 and D2. The mounting mandrel can be positioned at any point within the defined circle shown. Preferably, the distance between the longitudinal axis of the second bolt and the longitudinal axis A3 is greater than or equal to the distance between the longitudinal axis of the second bolt B2 and the longitudinal axis of the first bearing bolt B1. By rotating the second rotary mount D2 about the axis of rotation of the second bearing bolt B2, combined with rotating the first rotary mount D2 about the axis of rotation of the first bearing bolt B1, the Fig. The defined circle shown in Figure 5 represents a possible positioning for bolt A1. The eccentric bearing and the provision of two different axes of rotation allow for advantageous adjustment of the bolt in the horizontal plane. This ensures very precise and simple positioning of bolt A1, resulting in optimized coupling for transferring the support element from the lifting platform to the carrying device. Fig. Figure 5 also shows arm 4, which is arranged on the support element 3. The adjustment of the first rotary mount D1 takes place on the support surface 2d. The defined circle K is shown as a hatched area in Fig. 5 shown.

[0062] In Fig. Figure 6 shows another view of the first and second rotary mountings D1 and D2, as well as the arm 4 of the lifting platform 1. The arm 4 is swung out (swivel direction SR) and positioned in the area of ​​the first and second rotary mountings.

[0063] Fig. Figure 7 shows a support element 3 coupled to the gripping piece 5 of the arm 4. To pick up the support element 3 from the support device 2, the arm 4 is moved along the pivoting direction, with the slot 5c of the gripping piece 5 oriented in the pivoting direction (90° to the longitudinal axis of the arm). Therefore, during the pivoting movement of the arm 4, the gripping piece 5 can engage the bushing A2 via the slot 5c and at least partially enclose it. In a further step, after the bushing A2 has been at least partially enclosed by the gripping piece 5, the pivoting arm 4 can be lifted via the lifting platform 1, so that contact between the support element 3 and the contact surface of the gripping piece 5 is achieved. The bushing A2 is located in the gripping opening 5a, with the centering device 5b provided on the underside of the gripping piece 5.The contact surface of the support element 3 has, for example, a lower spherical section 3a (receiving sphere) which borders a plate-like section 3b. The plate-like section 3b, in turn, borders the side surface 3c of the support element 3 via its chamfer. To receive the support element 3 on the gripper 5, the plate-like section 3b rests on the upper contact surface of the gripper 5. The gripping opening encloses the spherical section 3a for horizontal fixation. The vehicle contact surface 3e of the support element 3 is located on the upper side of the support element 3. Preferably, this surface is made of an elastic or rubber-like material.

[0064] The centering device 5b can be designed as a centering plate. This centering device 5b facilitates the insertion of the bushing A2 into the gripping opening 5a of the gripper 5. In particular, the centering device 5b has an opening / slot with a smaller diameter than the gripping opening 5a. When the bushing A2 is inserted into the gripping opening 5a via the slot 5c, the centering device 5b thus enables more precise positioning of the bushing A2. When the swivel arm 4 is subsequently lifted, the support element 3 is therefore in a central position of the gripper 5, allowing the support element 3 to be optimally received in the gripping opening 5a of the gripper 5. The respective contact area of ​​the support element 3 is convex, so that inaccuracies in the positioning of the support element 3 or the gripper 5 can be easily compensated for.The gripping opening 5a also has at least one chamfer which runs along the outer circumference of the gripping opening 5a and facilitates the insertion of the receiving element 3 into the gripping opening 5a. The gripping piece 5 thus includes the centering device 5b, which is arranged opposite the contact side of the gripping piece 5 where the support element 3 can be received, and wherein the centering device 5b has a centering opening with a smaller opening width than that of the receiving ball 3a of the support plate 3 and centers, for example, on the bushing A2. The centering device 5b is ideally positioned concentrically to the receiving bore of the gripping piece 5.

[0065] The arm of the lifting platform is decoupled and swung out in a single pivoting operation by means of slots in the gripping piece that are rotated 90 degrees. In other words, slot 5c of gripping piece 5 is rotated 90 degrees to the longitudinal axis of arm 4.

[0066] In Fig. 8a and Fig. Figure 8b shows the rotary mounts D1 and D2. The first rotary mount D1 includes a circumferential contact surface D1a which projects parallel to the longitudinal axis of the first bearing bolt B1. This contact surface ensures ideal contact with the bearing surface 2d of the support device 2. Fig. 8b shown bushing A2 includes a groove A2n for guiding a pin on bolt A1.

[0067] For a procedure for transferring a support element from the vehicle lift to a vehicle skid, the following steps are suggested, for example: 1. The raised vehicle is driven to a specific height so that the respective, for example, spherical tip of the spring-loaded mounting pins can be easily inserted into the corresponding mounting bore of the mounting plate (support element 3). Each mounting pin is attached to two eccentrically mounted mounting plates (rotary mounts). This circular path adjustment allows any point within this path to be reached. 2. Once all the mounting pins are positioned or inserted into their respective mounting holes, the vehicle can be lowered further. The lowering movement is limited by a software stop and is coordinated with the vehicle skid. Upon reaching the software stop, the vehicle has already been transferred onto the skid with the support plates of the support element 3. 3. The swivel arms can now be swivelled into the basic position (starting position). 4. The vehicle can then be moved using the vehicle skid.

[0068] A procedure for transferring the vehicle skid onto the lifting platform may include the following steps: 1. The vehicle skid is positioned between or on the lifting platform. 2. The swivel arms are moved to the appropriate height. 3. The swivel arms can be swung in or placed against the guide tube of the skid's mounting mandrels using the centering plates (Pos. 5b). 4. The lifting platform can move further upwards. 5. The combination of the chamfer on the gripping pieces 5 and the receiving ball (Pos. 3a) of the support plate (Pos. 3) centers the support plate itself. 6. The vehicle is handed over to the stage as soon as the spring-loaded mounting pins are relieved of pressure and fully extended from the mounting bore. 7. Now the vehicle skid can be removed from the lifting platform.
