Definitions

  • the invention relates to a lifting platform for motor vehicles with lifting columns, on which two rails parallel to each other for spacing the vehicle wheels are vertically movable, at least one rail is also adjustable transversely to its longitudinal extent to the lift adjust different track widths, and being the adjustable track at least two lifting columns are assigned.
  • Lifts of the type described above are mainly used as four-column lifts built, with each track near its ends on a pair of lifting columns is vertically movable.
  • the object of the present invention is a Lift with the features of the preamble of claim 1 with respect to Adjustability of the rails or at least one rail in the transverse direction to improve, both in terms of the adjustment range, as well as the Synchronization of the adjustment movement relative to the two lifting columns.
  • the lifting platform according to the invention should be robust and inexpensive Award structure.
  • the invention is therefore based on the idea that the previous sliding guide Replace rail with a swivel bearing and the swivel levers in parallel to align with each other.
  • this parallel guidance allows you to have only one single drive for the adjustment of a travel rail is required because of tilting is excluded.
  • the swivel levers also allow larger ones Adjustment paths than the previous consoles, with another advantage being that the adjustment levers do not protrude under the work area below the vehicle need, as is the case with the consoles depending on the lateral displacement of the Rail is the case.
  • the lifting platform according to the invention is therefore distinguished also by a much better accessibility for the fitters.
  • a manually operated spindle drive can be used as the drive.
  • a motorized, especially an electric one is user-friendly or hydraulic drive connected to a program control. The operator then only needs the vehicle type or the desired one Type in the track width, whereupon the rails automatically fit into the right one Drive width.
  • the positioning of the drive for the cross adjustment is also available various possibilities. So the drive can be directly between the lifting column and Rail may be installed or between the pivot lever on the one hand and the lifting column or the rail on the other.
  • the swivel levers are preferably at the same height level as the travel rails - So arranged in about the same level. But it is also in the Within the scope of the invention, the swivel levers are offset somewhat vertically from the rails to arrange.
  • This tilting device is expediently positioned on the running rail. Alternatively, there is also a position on the swivel lever or on the lifting column into consideration.
  • an essential aspect of the invention is that the front End of the rails (without the sloping ramps) - in the direction of entry seen - only start behind the assigned front lifting columns. Thereby the accessibility of the vehicle is further improved, in particular with regard to the rear wheels on long vehicles, where on conventional lifts often the lifting columns are in the way.
  • FIGs 1 to 3 you can see four lifting columns 1 to 4, which in the usual way are anchored in the workshop floor.
  • Each of these Bearing bracket carries a horizontally pivoted pivot lever 5 to 8, the pivot levers 5 and 6 on one side of the lift parallel to each other are aligned and the pivot lever 7 and 8 on the opposite Side of the lift are also aligned parallel to each other. All four Swing levers are the same length and extend more or less in the Space within the four lifting columns.
  • Both Rails essentially have the known structure.
  • Figure 4 illustrates the structure of the pivot lever using the example of the lifting column 2 and of the lever 6. It can be seen that the pivot lever essentially consists of one rectangular hollow profile 6 a. This hollow profile is either terminal Bearing brackets, as shown on the underside, welded or, as on the Shown on top, a continuous reinforcement plate that protrudes from its Ends of the bearing bores. The swivel bearing on both Lifting column as well as on the running rail is carried out by plain bearings, especially via massive bolts.
  • the drive for the horizontal adjustment movement can be seen in FIG. 4, in the exemplary embodiment in the form of a threaded spindle 11.
  • This threaded spindle is pivotable on the one hand on the running rail 9, on the other hand on the pivot lever 6 stored. It can have a protruding end crossing the swivel arm 6 have to twist the spindle manually, for example via a hexagon bring about.
  • the spindle can also be operated by a motor, where it is recommended to position the servomotor inside the hollow swivel arm 6 to arrange.
  • a scale 12 for the swivel angle is appropriately scaled so that the track width belonging to the respective swivel angle.
  • Figure 5 shows the drive 11 in the form of a manually operated threaded spindle.
  • the threaded spindle is equipped with two flanges 11b and 11c, whereby it is rotatably supported in the flange 11b by its threads while it is rotatable in the flange 11c, but is axially immovable.
  • a rotation of the threaded spindle 11 leads to a relative movement between the two flanges 11b and 11c.
  • it has a hexagon 11a at its projecting end.
  • the threaded spindle is mounted in such a way that the flange 11b on Swivel lever, the flange 11c is mounted on the running rail.
  • Figure 6 shows a special embodiment of the pivot bearing between the pivot arm and mounting rail using the example of the swivel arm 6.
  • a bearing opening 14 is arranged which is considerably larger than the diameter of the bolt 13.
  • Eccentric sleeve 15 In the resulting annular gap is one Eccentric sleeve 15 inserted. It is rotatably mounted on the pin 13 and engages with its eccentric 15a in the bore 14.
  • the eccentric 15a Due to the weight load, the eccentric 15a is on the left of the bolt 13 lying side loaded by the swivel arm 6, whereas on the opposite A small annular gap can remain free - depending on the rotary position of the Eccentric.
  • the lifting platform according to the invention is characterized by extraordinarily favorable adjustability of the rails in the transverse direction with absolute Parallelism. You can also work with very narrow rails, which improves the accessibility of the vehicle. Last but not least, the Position of the lifting columns depending on the spatial conditions in the Workshop can be optimized.
