Definitions

  • the present invention relates to an apparatus and a method for setting up a lifting unit for lifting vehicles in order to enable a quick and safe positioning of the lifting unit at pick-up points on the vehicle.
  • the GB 2 082 795 A describes a control system for the motors of four portable lifting units that can be individually maneuvered to engage the wheels of a vehicle.
  • the US 2005/045429 A1 describes a lift system with user-selectable channels that coordinate the raising and lowering of a vehicle relative to a surface using wireless communication.
  • the US 2002/100901 A1 describes a lift system for lifting a vehicle with a plurality of wheels.
  • the system includes a controller that independently controls the extension and retraction of each lifting unit.
  • the object of the present invention is to provide a device which allows faster setting up of a lifting unit for lifting vehicles and thereby increases operating safety.
  • the device for setting up at least one lifting unit for lifting vehicles comprises a control unit, a remote control unit for transmitting control signals to the control unit, and a load sensor which transmits measuring signals to the control unit for determining the load of a lifting unit.
  • a remote control unit in the sense of this invention is a mobile control unit that a user can carry with him.
  • the lifting unit is positioned at receiving points of the object to be lifted and may include a lifting ram and load receptacles mounted on the lifting ram.
  • the load sensor can transmit load values directly to the control unit or also values (eg voltage values of a load sensor based on voltage measurements) on the basis of which the control unit can determine the load capacity.
  • the load sensor may be designed as a pressure sensor in the hydraulic system.
  • control unit receives control signals of the remote control unit and outputs corresponding control commands to the lifting unit.
  • both the lifting ram can be positioned vertically and in the longitudinal direction of the vehicle as well as the located on the lifting ram load receptacles are moved in the transverse direction.
  • control unit monitors based on the transmitted signals from the load sensor, the load of the lifting unit and interrupts the control of the lifting unit by means of the remote control unit, when the determined load of the lifting unit is greater than one is predetermined load point.
  • Load point in the context of this invention is a predetermined value for the load acting on a lifting unit, the achievement of this value means that the lifting unit is under load and the weight of the vehicle to be lifted at least partially acts on the lifting unit.
  • the control circuit ensures that after completion of setting up a lifting unit, characterized by reaching the load point, the remote control unit is deactivated.
  • the weight of the object to be lifted automatically generates a predetermined load against the force of the lifting unit when the receptacles on the lifting units are in contact with the receiving points of the object.
  • the control signals emanating from the remote control unit are then automatically deactivated.
  • the safety of the worker can be ensured in a particularly simple manner, since he can not lift the vehicle due to the deactivated remote control unit as long as he is under the vehicle, where his safety in case of incorrect positioning of the lifting unit on the vehicle when lifting the vehicle can not be guaranteed can.
  • the lifting units can be controlled individually with the remote control unit, wherein the control unit is set to suppress control by means of the remote control unit of those lifting units whose determined load is greater than a predetermined load point of this lifting unit.
  • the remote control of this lifting unit is suppressed, while the other Lifting units that have not yet reached their load point can still be positioned with the remote control unit.
  • the control unit can be set up in such a way that only one lifting unit for setting up can be moved with the remote control unit while the other lifting units are blocked. This avoids that a user who is to set up in the vicinity of the lifting units, injured by a second moving lifting unit, which he has not in sight.
  • the lifting unit can be moved with the remote control unit into a first position in which images located on the lifting unit can be positioned vertically below receiving points of an object to be lifted. Furthermore, the lifting unit with the remote control unit can be moved to a second position, are in contact with the receptacles of the lifting unit with receiving points of an object to be lifted. This can ensure that after the horizontal alignment of the images, they can be brought in a particularly simple manner by vertical method safely in contact with the receiving points of the object to be lifted.
  • At least one illumination unit and / or at least one image acquisition unit can be provided on the lifting unit, and at least one image output unit can be provided on a fixed operator control unit and / or the remote control unit for the reproduction of the data recorded by the image acquisition unit.
  • a lighting unit can also be provided on the remote control unit, with which the user can illuminate the working space under the vehicle.
  • the lifting unit may be executed in underfloor construction and / or is located in a pit which is arranged in a bottom surface. Furthermore, the free areas of a pit opening, which may be arranged in a floor surface, may be at least partially concealable with mobile cover units. This ensures in a particularly simple manner that through the pit opening, which is necessary to move the lifting unit in the longitudinal direction of the object to be lifted, no objects or people can fall into the pit. Thus, the lifting unit is secured against damage and extended their life.
  • the control unit can calibrate at the load point to a common starting value.
  • the movement of the lifting ram is quasi-synchronous.
  • the movement of the lifting ram is synchronized, so that the stroke difference of the individual lifting ram during the lifting process is less than 50 mm.
  • the mounting points for the lifting units on a truck can be at different heights. Therefore, it is important that after setting up the lifting units, i. After positioning the lifting units and reaching the load point, the positions of the lifting units are calibrated to a common starting value.
  • data concerning the position of the pickup points on the items to be lifted may be transmitted through the wireless remote control unit wired remote control unit and / or the stationary control unit are input to the lifting device and / or stored in a database located in one of said control units.
  • This can be stored in a particularly simple manner, the coordinates of the recording points of the objects in the form of a database in the lifting device. Since, for example, the same types of trucks have the same coordinates of pick-up points, this results in the advantage that the coordinates of the pick-up points do not have to be reentered for each item of the same type or type to be lifted.
  • a fixed reference point for determining the position of the vehicle is still required.
  • the stored pick-up points determine the position of the pick-up points relative to this fixed reference point.
  • This fixed reference point can be specified, for example, by means of a wheel well into which the vehicle enters.
  • the remote control unit can be a wireless remote control unit. This increases the freedom of movement of the worker in often limited by the vehicle and the lift working space and reduces the risk of tripping through lying cable strands.
  • a first lifting unit may be stationary in a substantially horizontal direction, wherein at least one further second lifting unit may be displaceable in a predetermined, substantially horizontal longitudinal direction of an article to be lifted.
  • control unit can be set up such that the lifting units can be moved at different speed levels during the setting-up process.
  • control unit may be configured such that for positioning in a first position, the lifting unit is moved quickly and for positioning in the second position until reaching the load point is slowly movable.
  • a fast method of lifting unit would be dangerous because in a dangerous situation, the first user could not stop the lifting dies himself and the response time of the second user to the stationary operating unit would take too long.
  • a user who is equipped with a mobile remote control unit for setting up the lifting units even with a quick movement of the lifting unit in the first position to monitor their correct alignment and positioning in the vicinity of the lifting reliable.
  • control unit and the remote control unit for removing and installing aggregate units can be used.
  • the lifting units are relieved after setting up and lifting the vehicle by jacking the vehicle, so that the load of the lifting units falls below the load point. After falling below the load points of the lifting units they can be controlled again with the remote control unit.
  • a user located below the jacked-up vehicle positions a lifting unit by means of the remote control unit under the vehicle assembly to be picked up.
  • the carrying capacity of vehicle aggregates is generally smaller than the predetermined load point of the lifting unit, so that by means of the remote control unit, the lifting unit under load, ie with the recorded aggregate, and can be lowered independently of the movement or position of the other lifting units.
  • the method for setting up at least one lifting unit for lifting vehicles comprises the positioning of a lifting unit by means of a remote control unit into a first position in which shots located on the lifting unit are positioned vertically below receiving points of an object to be lifted.
  • the method further comprises positioning a lifting unit by means of a remote control unit in a second position, in which the recordings of the lifting unit are in contact with the receiving points; and measuring the load of a lifting unit.
  • the method comprises monitoring the load of a lifting unit; and interrupting the actuation of the lifting unit via the remote control unit when the determined lifting capacity of the lifting unit is greater than a predetermined load point.
  • the method may comprise the step of, after reaching the load point of the lifting unit, sending a control signal for locking the lifting unit and for deactivating the remote control unit, and controlling the lifting unit by means of control signals received by a stationary operating unit.
  • the present invention enables a fast, cost-effective and user-friendly setting up of one or more lifting units for lifting vehicles.
  • the presence of a remote control can control the orientation of recordings from anywhere.
  • a worker monitoring the alignment also takes control of the lift unit. Merging these two functions to one person can significantly speed alignment. Thus, especially in workshops with high utilization, the efficiency can be improved and the staffing requirements are reduced, since only one worker for aligning and controlling the lifting system is needed.
  • the control unit according to the invention meets the high safety requirements in the operation of lifting platforms, since after reaching the load point, the control of the respective lifting unit is automatically deactivated via the remote control unit.
  • This can ensure a particularly simple way worker safety, since he can not lift the vehicle due to the deactivated remote control unit as long as he is under the vehicle, where his safety in case of incorrect positioning of the lifting unit on the vehicle when lifting the vehicle can not be guaranteed .
  • By providing a camera and a lighting unit on the lifting units or the remote control unit, as well as an image output unit on the control units the workers no longer have to go under the objects to monitor the alignment, which means the risk of burns on hot exhaust parts or sharp-edged injuries Objects is reduced.
