Definitions

  • the invention relates to a lifting spindle for lifting a Seilandrückwalze.
  • Seiland Wegwalzen find use in connection with winches as an example in recovery tanks.
  • the Seilandschreibwalze pushes the rope spring biased against the winch drum to allow a more defined winding and unwinding.
  • the cable pressure roller In case of defects on the cable winch, the cable pressure roller must be raised against the spring preload to allow removal of the winch.
  • the rope pressure roller is, with the winch, in the crane boom, which makes the removal and installation under consideration of accident prevention regulations impossible.
  • the invention described in claim 1 is based on the problem to create a way the Seiland Wegwalze, for removal and installation of the winch in the crane boom of a recovery tank, taking into account all accident prevention regulations to raise.
  • a lifting spindle for lifting a Seiland Wegwalze in which a hook is rotatably supported on a threaded spindle, which in turn is supported by a nut of a pivot bearing, which is supported on two bearing blocks on a base plate are held and the base plate has a hole pattern which is identical to the hole pattern of a maintenance cover on a crane boom and the base plate, in working condition, screwed on the crane boom is held, solved.
  • the advantage of the invention is that the hook is adapted to the circumference of the Seiland Wegwalze and this securely wraps around. Further, the hook is formed in the region of the connection point to the threaded spindle as a sleeve, which allows a rotatable fixing of the hacking on the threaded spindle.
  • the actual lifting work is performed by the mother of the pivot bearing whose thread pitch is designed to be self-locking for safety reasons.
  • the pivot bearing in turn is advantageously rotatably supported in bearing blocks to compensate for the naturally occurring rotation of the Seilandrückwalze to the bearing point of the holder of the Seilandschreibwalze.
  • the base plate on which the bearing blocks are fixed has the same hole pattern as the maintenance cover for the winch on the crane arm of the recovery armor. A releasable fixing of the lifting spindle in the operational state is thus enabled.
  • a particularly advantageous embodiment of the lifting spindle according to the invention is described in claim 2.
  • the lifting spindle is fixed in operational condition on the crane boom of a recovery tank.
  • the maintenance cover is removed and the base plate of the lifting spindle with the screws of the maintenance cover on the crane arm of the recovery armored support.
  • the nut of the pivot bearing is rotated counterclockwise until the hacking squeezed around the pressed Seilandrückwalze.
  • the nut of the pivot bearing is turned clockwise, whereby the cable pressure roller is raised.
  • the single FIGURE 1 shows the lifting spindle according to the invention in a perspective view.
  • FIG. 1 a hook 1, which has on its side facing away from the threaded spindle 2 a rounding, which corresponds to the Seilandrückwalze and on its threaded spindle 2 side facing a sleeve.
  • the hook 1 is rotatably supported in the threaded spindle 2.
  • the threaded spindle 2 passes through the pivot bearing 3 and is fixed by the nut of the pivot bearing 4.
  • the pivot bearing 3 is rotatably supported in bearing blocks 5, which are supported on the base plate 6.
  • the base plate 6 has a hole pattern 7, which corresponds to that of the maintenance cover for the winch on the crane boom of a recovery tank.
