Definitions

  • the invention relates to a pull-out device for pan sinks with a pulling device which can be connected to the sink via a pull rod.
  • a pull-out device for a gas purging plug is known from DE-A1- 33 30 105, which consists of a frame on which a threaded spindle is provided, which can exert tensile forces on the pull rod connected to the purging plug to be pulled out.
  • Pulling out a sink is a delicate and difficult task, since on the one hand relatively large forces have to be exerted on this sink in order to detach it from the perforated block, but on the other hand damage to the brickwork is to be prevented.
  • the pull-out device described in this prior publication a metered application of force is now possible, but the forces that can be exerted by such a device are not always sufficient to detach a sink from its seat.
  • DE-Al-38 33 504 pull-out devices which exert corresponding tensile forces on the sink by driving in a driving wedge.
  • a driving wedge In order to be able to ensure correspondingly large forces, such a driving wedge must have a relatively small pitch angle. It is therefore necessary to make an exact adjustment of the pull-out device before driving in the driving wedge, since otherwise the driving wedge can either not be used or an insufficient amount of the wedge is available for driving out. It is an object of the present invention to avoid these disadvantages and to provide a pull-out device for pan sinks, which can exert large forces on the sink, is simple and easy to use, and avoids damage to the sink or perforated stone through the application of force .
  • a device which, in addition to the forces which can be transmitted from the pulling device to the sink, can exert impulsive forces on the sink.
  • the pulling device can be dimensioned relatively weak in the present invention, since it only has to exert part of the force required to expel the sink. Only very loose sink stones can be pulled out by the pulling device alone. For tightly fitting sink stones, an impact force can also be applied. Surprisingly, it has been found that the superimposition of a lower, continuously acting force with a force acting in a jerk manner results in a substantial improvement when pulling out sink blocks.
  • the device for exerting additional forces is designed as an opening in the pull rod, which is provided for receiving a driving wedge.
  • the driving wedge makes it possible to apply very large forces in abrupt fashion, although it is also possible for the average fitter to dose these forces to some extent.
  • the pull-out device according to the invention can be handled particularly simply and safely if the pulling device is designed as a hydraulic cylinder.
  • FIG. 1 shows a pull-out device according to the invention in a partial section in the longitudinal direction
  • FIG. 2 shows a top view of the pull-out device from FIG. 1
  • FIG. 3 shows an end view of the pull-out device from FIG. 1.
  • the sink 1 seated in a perforated brick 12 can be screwed via its gas connection tube 2 to a pull rod 3 of the pull-out device.
  • This tie rod 3 is coupled to a hydraulic cylinder 6 by means of a coupling bolt 4 via a yoke 5.
  • the hydraulic cylinder 6 is supported on the pan base 8 via a frame 7.
  • An opening for receiving a driving wedge 9 is provided in the pull rod 3.
  • An interchangeable spacer 11 can be inserted between this driving wedge 9 and a plate 10 connected to the frame 7.
  • the pan is usually brought into a lying position, the pan base 8 being in a vertical position.
  • the pull rod 3 is screwed onto the gas connection tube 2.
  • the pull-out device is then suspended in an angle iron 13 welded to the pan base 8 as a holder, so that the frame 7 is supported on the pan base 8.
  • a plug connection between the yoke 5 and the pull rod 3 is made by means of the coupling bolt 4.
  • a spacer 11 is placed on the plate 10, the thickness of which is such that a driving wedge 9 can be inserted with its narrow side into the opening of the pull rod 3. Then the driving wedge 9 is driven into the opening with hammer blows. The hammer blows and thus the extraction process are stopped when it can be seen that the sink has loosened. The extraction device is then disassembled by loosening the driving wedge 9 and the coupling bolt 4, unhooking the extraction device from the angle iron 13 and removing the sink 1.
  • the present invention makes it possible to remove sink blocks from the perforated blocks in an extremely safe and reliable manner.
