Definitions

  • the invention relates to a support frame of a lifting platform for motor vehicles, the support frame having cushion bodies for receiving the vehicle frame.
  • Lifting platforms with a supporting frame are known in various designs.
  • a lifting platform is known in which the lifting frame consists of four pairs of scissors arms arranged on a base plate, the lifting movement being carried out by an air bellows arranged between the base plate and the lifting table as a supporting frame.
  • rubber blocks preferably four rubber blocks, must be placed on the lifting table at certain points, which hold the vehicle at the points provided on the frame bars to capture. The attachment of the rubber blocks on the lifting table is extremely cumbersome because the operating personnel have to bend over or go under the vehicle.
  • Another disadvantage is that after placing the rubber blocks on the lifting table of the lift there is a distance between the frame and the rubber block. Before the vehicle is lifted by the lift, this distance must first be overcome; it therefore represents an idle stroke for the lift, since this distance is no longer available at the maximum lift height of the lift.
  • a support frame of a lifting platform is known in which cushions filled with fluid are arranged on the cross members.
  • the liquid pressure in the respective cushion is dimensioned so that the vehicle to be lifted presses with its corresponding frame part into the fluid cushion to such an extent that practically the entire area of the frame resting on the cushion is exposed to the same contact force.
  • an H-shaped lifting platform in which cushion bodies are provided on the cross members, which bear against the frame parts of the vehicle during lifting.
  • the task of these upholstered bodies is to provide the frame parts lying on them with as large a contact surface as possible in order to keep the surface pressure low in order to counteract deformations on the frame parts.
  • these known upholstery bodies or pillows also have the disadvantage that the upholstery bodies have to be subsequently brought by the operating personnel by hand under the corresponding places on the frame. In addition, an empty stroke of the lift cannot be avoided even with the above-described configurations of upholstered bodies.
  • the invention is therefore based on the object, starting from the prior art, to provide a cushion body which does not have to be brought into the area of the load-bearing frame parts by the operating personnel after the vehicle has passed over the lifting platform, and which also has an idle stroke the lift is avoided.
  • the cushion body is designed as an inflatable air cushion body.
  • the arrangement of inflatable air cushion bodies as support elements for the frame of a motor vehicle ensures that the motor vehicle can drive over the already placed support element, since it only fulfills the supporting function when it is filled with air.
  • the height of the pleasure cushion body is so low that no resistance is offered for the vehicle to be run over; i.e. Even for lowered vehicles there are no problems when driving over a support frame provided with such cushion bodies as support elements.
  • the support frame is designed as a lifting table; nevertheless, the use of such inflatable air cushion bodies is also possible on lifting platforms with supporting frames, as are known for example from DE-PS 33 09 902.
  • a particularly advantageous embodiment of a lifting table is characterized in that the lifting table has, parallel to the drive-over direction, on both sides a drive-over web offset from the height of the central part of the lift table, on which at least one inflatable air cushion body is arranged.
  • the crossing web advantageously extends beyond the base plate in its lateral extent.
  • the advantage of this embodiment is that no ramps arranged in front of and behind the lifting platform are required to drive over the lifting platform by a vehicle.
  • the lifting table has a crossmember which is arranged transversely to the direction of travel and has the same cross section as the lifting table.
  • the traverse takes up two air cushion bodies in the area of the drive-over web; a further two air cushion bodies are located opposite each other on the drive-over webs of the lifting table.
  • the traverse is arranged displaceably on the lifting table in the direction of travel.
  • each air cushion body is protected by a flexible protective element, e.g. a tab, covered.
  • each drive-over web has an inflatable air cushion body which extends over its entire length.
  • a boom extending over the entire length of the ramp can also be provided, which has approximately the width of the ramp and which is hingedly connected to the ramp.
  • the air cushion body is connected to the outer edge of the boom by a supporting element, for example a soft plastic plate extending over the length of the air cushion body.
  • the soft plastic plate also serves to protect the air cushion body from external influences.
  • the lifting platform shown here, for example, as a short-stroke lifting platform, consists of a base plate labeled 1, a lifting frame 2 consisting of four pairs of scissor arms and the lifting table labeled 3 as a whole.
  • the lifting table 3 here consists of a central part 4, to each of which a drive-over web 5 is assigned, which is offset from the height of the central part 4 of the lifting table.
  • the arms 6 are articulated to the ramp 5.
  • the air cushion body 7 is fixedly arranged on the drive-over web 5. A piece of fire hose can be used as the air cushion body.
  • the air cushion body 7 and the boom 6 are each connected to one another by a soft plastic plate 8. If the frame spar of a vehicle is located directly above the air cushion body 7, then when the air cushion body is inflated, the boom 6 is pulled upwards, that is to say folded upwards (FIG. 2).
  • the soft plastic plate 8 prevents damage to the air cushion body.
  • this measure of connecting the air cushion body 7 to the boom 6 extends the area of application of such a lifting platform to wider vehicles.
  • the plastic plate 8 lies almost flat on the extension arm 6 and the drive-over web 5 (shown in dashed lines in FIG. 2).
  • the lifting platform also shown here as a short-stroke lifting platform, consists of the base plate labeled 1 and the frame 2 consisting of four pairs of scissor arms and the lifting table labeled 3 in total.
  • the lifting table 3 consists of the middle part 4, to which the drive-over web 5 is assigned on both sides.
  • the height of the ramp is set down compared to the height of the middle section of the lifting table.
  • the crossbar 9, which is longitudinally displaceable in the direction of travel, is arranged on the lifting table 3.
  • the crossmember 9, which has the same cross section as the lifting table 3, also has a central part 4 'with a crossing web 5' arranged on both sides.
  • the crossmember 9 is connected to the lifting table 3 by guide means 10.
  • the guide means 10 consists, for example, of a square profile 10a attached to the crossmember 9, which is guided in a correspondingly designed square profile 10b arranged on the lifting table.
  • the cross member 9 has two inflatable air cushion body 11 in the area of the drive-over webs 5; a second pair of inflatable air cushion bodies 11 is in each case arranged on the drive-over webs 5 of the lifting table at the ends of the lifting table opposite the crossbar.
  • the cushion bodies 11 are each covered by tabs 12, for example in the form of rubber flaps, in order to avoid damaging the actual cushion body, and a piece of a fire hose can again be used as the inflatable air cushion body.
