Definitions

  • the invention relates to a lifting platform, in particular for a motor vehicle, having the features of the preamble of claim 1.
  • a lifting platform for a motor vehicle which is based on a scissor frame and an air bellows.
  • a support plate and a stand plate are connected to one another by the scissor frame, with the support plate and the stand plate simultaneously representing the closing plates for the air bellows.
  • the air bellows are arranged on the side of the scissor frame.
  • a lifting platform with two pairs of scissor arms and an air bellows is known.
  • the scissor arm pairs connect a base platform and a lifting table to one another in such a way that the lifting table is raised or lowered when the air bellows is filled or emptied.
  • the air bellows is supported on the one hand on the lifting table and on the other hand on a receptacle which extends between the two pairs of scissor arms and is located approximately at the level of a pivot point of the scissor arms.
  • the recording is connected to the lifting table by a steel cable, which is intended to ensure that the recording is always kept horizontal. It is accepted that during the lifting movement an offset occurs between the two opposite end faces of the air bellows, which leads to shearing of the air bellows.
  • the lifting mechanism comprises two pairs of scissor arms, each with two scissor arms connected to one another in an articulated manner.
  • the air bellows is placed between two plates, one above and the other below the Hinge point is attached to the opposing scissor arms of the two scissor arm pairs.
  • the air bellows thus acts in the vertical direction between the two plates.
  • the two plates are aligned in the vertical direction and are arranged at the same distance from the pivot point, which is intended to prevent the air bellows from being sheared during the lifting movement.
  • the object of the invention is to present a lifting platform with a reduced space requirement without having to accept restrictions in relation to the maximum achievable lift and/or the achievable load-bearing capacity.
  • the invention is based on the finding that although a narrow construction can be achieved with the lifting platforms known from the prior art, a small stroke must be accepted for this. In order to achieve a greater lift, on the other hand, a greater width of the lifting platform must be accepted. According to the invention, this conflict of objectives is solved in that an air bellows of a lifting platform is arranged in an area outside of a scissor system of the lifting platform, which allows a narrow structure to be implemented, and at the same time a transmission system is provided with which a transmission of a change in distance caused by the air bellows is achieved and thus large strokes can also be achieved with the narrow construction according to the invention.
  • a lifting platform according to the invention has a base platform and a lifting platform that can be lifted relative to the base platform.
  • the base platform serves in particular as a contact area and for supporting the lifting platform with respect to a floor surface on which the lifting platform is installed.
  • the lifting platform serves in particular to accommodate an object to be lifted.
  • the lifting platform can include two track rails for accommodating a vehicle.
  • the lifting platform has a lifting device for performing the lifting movement of the lifting platform in relation to the base platform.
  • the lifting device includes a scissor system and an air bellows.
  • the scissor system connects the base platform and the lifting platform.
  • the connection can be made directly or also indirectly by further connection means.
  • the lifting platform is supported against the base platform via the scissor system.
  • the scissor system serves in particular to guide the lifting movement of the lifting platform in relation to the base platform.
  • the scissor system can be used to ensure that the base platform and the lifting platform are preferably aligned essentially parallel to one another over the entire lifting movement.
  • the scissor system can comprise two pairs of scissor arms which connect the base platform and the lifting platform to one another on opposite sides.
  • the superimposed ends of the scissor arms of each pair of scissors can be rotatable on one side, but otherwise firmly connected to the lifting platform or the base platform, while the scissor arms are movably accommodated on the lifting platform or the base platform on the other side.
  • the movably received ends of the scissor arms move along the lifting or base platform towards the ends of the scissor arms that are firmly connected thereto, so that the scissor arms are transferred to their extended position.
  • the sequence of movements is reversed, i. H. the movably received ends of the scissor arms move away from the fixed ends so that the scissor arms are transferred to their lowered position.
  • a double scissors system can also be used instead of a simple scissors system.
  • the scissors system can also comprise more than two pairs of scissors arms arranged one above the other.
  • the air bellows can be optionally filled and deflated to raise or lower the lifting platform relative to the base platform.
  • a distance between the lifting platform and the base platform is specified by the distance between two bearing surfaces of the Air bellows, the spacing of which depends on the filling level of the air bellows.
  • the air bellows can be essentially barrel-shaped or column-shaped, with the bearing surfaces being the opposite end faces of the air bellows in the longitudinal direction of the air bellows.
  • the air bellows in the lifting platform according to the invention are arranged in an area outside of the scissor system.
  • the air bellows and the scissor system can e.g. B. be arranged one behind the other or side by side in the direction of travel of the lift. i.e. a minimum distance z. B. between the two scissor arm pairs of the scissor system is not specified by the air bellows. Rather, they can be arranged at practically any small distance from one another.
  • the lifting device of the lifting platform includes a transmission system with which a change in the distance between the bearing surfaces can be translated into a change in the distance between the lifting platform and the base platform that exceeds this change in distance.
  • the absolutely achievable stroke is not limited to the absolutely achievable change in distance between the bearing surfaces.
  • the transmission system can be arranged and designed in such a way that a transmission ratio of 1 to 2 is achieved, i. H. a change in the distance between the contact surfaces of the air bellows translates into twice the change in distance between the lifting platform and the base platform.
  • the lifting platform according to the invention can be used for lifting motor vehicles z. B. be used in the workshop area.
  • the lifting platform can be flexibly adapted to a track width of the motor vehicle on the one hand.
  • the lifting platform can also be adapted in particular to narrow track widths due to its narrow structure.
  • a sufficiently high stroke can be achieved with a sufficiently high load capacity at the same time.
  • the lifting platform according to the invention e.g. B. in the construction sector etc.
  • the translation of the change in distance between the contact surfaces can be achieved in various ways.
  • the bearing surfaces can be connected to the base platform and the lifting platform via a lever system, with the lever system converting a movement of the respective bearing surface relative to the other bearing surface to a corresponding movement of the lifting platform relative to the base platform.
  • the translation system includes a support platform connected to the scissors system.
  • the air bellows is supported with one of its bearing surfaces on the support platform. A change in the distance between the bearing surfaces of the air bellows can thus be transferred directly to the scissor system via the support platform.
  • the support platform can be arranged between the base platform and the lifting platform and can extend substantially parallel thereto.
  • the air bellows can z. B. between the base platform and the support platform and be supported in particular with its one contact surface on the support platform, while it is supported directly or indirectly with the other contact surface on the base platform. A particularly stable construction can be achieved in this way.
  • the air bellows can be arranged, for example, between the support platform and the lifting platform.
  • the connection of the outrigger platform to the scissor system can be at any point between the respective points of connection of the scissor system to the base platform and the elevation platform.
  • the support platform can be connected to the scissor system at a pivot point by which two scissor arms of the scissor system are articulated to one another.
  • the pivot point is usually about halfway up the scissor system.
  • a transmission ratio of 1 to 2 can be achieved in a simple manner.
  • the support platform can be connected to one or both scissor arms in an articulated manner at the pivot point. the The mobility of the two scissor arms relative to one another is therefore not impaired, or at least not significantly impaired.
  • the transmission system also has a scissor system.
  • This can be a scissor system that is separate from the scissor system of the lifting device.
  • the scissor system assigned to the support platform is referred to below as the additional scissor system.
  • the further scissors system can in particular have two pairs of scissors arms which are arranged on opposite sides of the support platform.
  • the support platform can be extended on both sides via a pair of scissor arms, e.g. B. on the base platform.
  • a symmetrical and particularly stable structure can thus be achieved.
  • the air bellows can be arranged in a region outside the further scissor system for guiding the movement of the support platform, as seen in a projection onto the support platform.
  • the support platform can have two adjacent areas, one of which serves to connect the additional scissor system and the other to connect the air bellows.
  • the additional scissor system can in particular support the support platform in relation to the base platform, which can be moved in the lifting direction. i.e. a lifting force caused by the air bellows causes the support platform to be raised relative to the base platform guided by the scissor system.
  • the additional scissor system can be connected in an articulated manner to the scissor system by which the lifting platform and the base platform are connected to one another. A movement of the scissor system can thus be coupled with a movement of the further scissor system.
  • a scissor arm of the other scissor system can be attached in an articulated manner to the pivot point of a pair of scissor arms of the scissor system.
  • the additional scissor system can have a scissor arm that is separate from the scissor system of the lifting device and is connected in an articulated manner to a scissor arm of the scissor system of the lifting device.
  • the ends of the scissor arm of the other scissor system are z. B. on the one hand connected to the support platform and on the other hand to the base platform.
  • a scissor system for guiding the movement of the support platform is thus formed on the basis of the scissor arm that is present anyway, with only one further separate scissor arm.
  • the scissor arm of the lifting device acts as a second scissor arm for the other scissor system.
  • At least one scissor arm of the further scissor system is connected both to the base platform or to an intermediate platform arranged on the base platform and to the support platform by means of a floating bearing.
  • this scissor arm forms a pair of scissor arms together with another scissor arm, with the other scissor arm being formed by one of the scissor arms of the scissor system of the lifting device or being articulated to the pivot point of the pair of scissor arms of the scissor system of the lifting device.
  • the loose bearing by which the at least one scissor arm of the further scissor system is connected to the support platform, has a roller or sliding element.
  • the roller or the sliding element can be attached at the end to the scissor arm. A movement of the roller or the sliding element is guided by means of a guide rail attached to the support platform.
  • the floating bearing is implemented as a type of linear guide in the form of a roller or sliding guide.
  • the support platform of the translation system can have a z. B. essentially U-shaped frame and recorded by the frame support plate, wherein the air bellows is supported with its contact surface on the support plate.
  • the frame and the support plate can be formed as separate components which are connected to one another to form the support platform. However, it can also be a one-piece structure.
  • two legs of the frame protrude beyond the support plate in the longitudinal direction of the support platform.
  • the two protruding legs are connected to the scissor system and in particular to the pivot point of the opposite pairs of scissor arms of the scissor system.
  • the position of the hinge point of the scissor system can shift in the longitudinal direction as part of the lifting movement, viewed in projection onto the base platform. i.e. if the support platform is connected to the scissor system at the hinge point, it can happen - without further measures - that the support plate also moves in the longitudinal direction during the lifting movement. This can cause the air bellows to shear.
  • the frame of the support platform and in particular the protruding legs are telescopic.
  • the displacement of the connection point with the scissor system that occurs during the lifting movement can be compensated for by extending or retracting the support platform and in particular the protruding legs.
  • the support plate thus maintains its position in the projection onto the base platform throughout the entire lifting movement.
  • a further possibility for preventing the air bellows from shearing during the lifting movement is a laterally displaceable mounting of the support plate on the frame.
  • the translation system and the air bellows z. B. are arranged to be displaceable relative to the base frame in the direction of travel.
  • This can e.g. B. an intermediate platform can be provided on which the air bellows is supported with its contact surface, the intermediate platform being displaceable on the Base platform is stored.
  • the transmission system and the air bellows can follow a movement of the articulation point during the lifting movement, in order to prevent the air bellows from shearing.
  • the translation system can be designed and arranged in such a way that, when the lifting platform is in a retracted position, it is accommodated in receptacles provided for this purpose in the base platform and/or the lifting platform, viewed in the lifting direction. In this way, the overall height of the lifting platform in its retracted position can be as low as possible.
  • the scissor arms of the scissor system and/or the translation system can also be cranked or provided with corresponding recesses so that they can be stowed next to each other in the retracted position to save as much space as possible.
