Description

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). 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. A detachable lifting platform mount is, for example, from the DE 10 2017 100803 A1 It is known that a motor vehicle is lifted onto a support device or a two-post lifting platform via four mounting points. The vehicle skid has two sliding crossbeams, each with mounting points at its end for holding the motor vehicle. 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. These tasks are solved by the characteristics of independent claims. Advantageous further developments can be found in dependent claims. 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 reception of the support element is also ensured by the bolt that is displaceable along the longitudinal axis and can preferably be inserted into an opening in the support element. According to the invention, a transfer system is proposed with which a simple and precise positioning of the end connection with respect to the support element is achieved, so that a process-reliable and error-free transfer of the support element from the lifting platform to the carrying device or vice versa can be provided. 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 provided to receive the support element, and the end connection incorporates the movable bolt. Since 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, the coupling point of the support element can be easily accessed. By appropriately rotating the first and/or second rotary joint, the movable bolt can be moved along a horizontal plane so that, 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 sliding bolt 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 carrying device. The contact takes place 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 terminal. The weight of the support element, and especially of any object positioned on it, ensures secure contact between the support element and the end terminal. Therefore, a particularly robust and reliable, yet simple and process-safe transfer system can be provided. 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 b
