Definitions

  • the invention relates to a lifting platform according to the preamble of claim 1.
  • Such a lifting platform is known from WO95 / 11190.
  • the known lifting platform has two lifting surfaces for lifting one Vehicle, especially motor vehicle, each of which an associated hydraulic lifting device is lifted from a lifting cylinder and a lifting piston.
  • To control a synchronous movement of the two lifting surfaces is a relatively complex control system with control valves intended.
  • the object of the invention is a lift of the beginning to create the type mentioned, with which with reduced effort a synchronous movement of the two lifting surfaces is achieved becomes.
  • two actuating pistons of a pump device provided, of which a respective actuating piston is assigned to a lifting piston of the lifting device.
  • the transmission of motion between the actuating piston and the reciprocating piston takes place via a movement transmission medium, especially a hydraulic fluid that is incompressible and in a closed cycle between the two respective pistons, d. H. between an actuating piston and a reciprocating piston is located.
  • the two actuating pistons are rigid with each other connected.
  • the pump device can have two pump cylinders in which the actuating piston can be acted upon by a pressure medium are.
  • the print medium can be from a motor-powered Pump will be delivered.
  • the invention avoids that a non-uniform movement of the lifting surfaces takes place. This is guaranteed by the rigid connection the two actuating pistons of the pump device, which together with the reciprocating pistons the limits of the closed assigned circuits for the movement transmission medium, especially form the hydraulic fluid.
  • the rigid connection creates a synchronous movement the actuating piston has reached. The synchronous movement these two pistons are on the compressible motion transmission medium transferred to the two reciprocating pistons. In this way, the synchronous lifting movement of the two is achieved Lifting surfaces, in upward and downward direction.
  • FIG. 1 In the figure is a lifting system, in particular Electro-hydraulic lifting system shown, which two Has lifting surfaces 1 and 2.
  • the two lifting surfaces 1 and 2 are via an associated mechanical motion transmission device 16, 17 connected to a reciprocating piston 5, 6.
  • Each reciprocating piston 5, 6 is in a reciprocating cylinder 3, 4 arranged movably in the axial direction.
  • the respective piston 5 or 6 and the associated lifting cylinder 3 or 4 form together with the respective mechanical motion transmission device 16 and 17 a lifting device, the is assigned to the respective lifting area 1 and 2.
  • the respective mechanical motion transmission device 16, 17, is preferably designed as scissors. However, it is also possible, the piston movement directly on a lifting ram to transfer the lifting surfaces 1 and 2.
  • each actuating piston 7 and 8 is in a separate one Pump cylinders 12 and 13 movably guided in the axial direction.
  • a closed circuit 10 or 11 is an incompressible movement transmission medium, especially a hydraulic fluid. With this movement transmission medium, too Spaces in the respective lifting cylinder 3 or 4 below the lifting piston 5 or 6 and the cylinder rooms above the two Actuating piston 7 or 8 filled.
  • the circuit 10 acts it is a cylinder chamber 18 below the reciprocating piston 5 and a cylinder chamber 20 above the actuating piston 7.
  • the circuit 11 is the cylinder space 19 below the reciprocating piston 6 and the cylinder chamber 21 above the actuating piston 8.
  • the two actuating pistons 7, 8 are powered by a pressure medium, which is supplied by a pump 14.
  • the pump 14 is to the pressure chambers 25 and 26 of the Pump cylinders 12 and 13 connected.
  • the pressure chamber 25 is located itself below the actuating piston 7 in the pump cylinder 12 and the pressure chamber 26 is below that Actuating piston 8 in the pump cylinder 13.
  • the pump 14 is driven by a pump motor 15.
  • the lifting system shown is due to a simple structure insensitive to interference. It will be a fine-tuned one synchronous lifting movement of the two lifting surfaces 1 and 2 reached. The effort for the maintenance of the lifting system is small due to its simple structure. This will also achieved safe operation of the lifting system.
