Definitions

  • the invention relates to a hydraulically operated peeling device according to the preamble of claim 1.
  • a hydraulically operated accident rescue device with an expanding beak is known.
  • Various tools can be used at the tips of the expanding beak, so that the accident rescue device can also be used to insert a manhole into an accident-damaged vehicle when using a clamping jaw and a peeling jaw, in order to enable the rescue teams to access the interior of the vehicle.
  • the applicant's publication HR 411 65 / 3D / E5 "Lukas rescue systems" shows in the photo on the bottom right on the last page the use of a spreader with a clamping and peeling jaw as a peeling device for making a manhole.
  • the clamping and peeling jaws are e.g. shown on page 3 of the brochure and its application on page 15, item 509/510.
  • the peeling jaw can advantageously be arranged on a slide (claims 2, 3 and 4) or directly or via an extension on the piston rod (claims 5, 6 and 7).
  • the slide, the peeling jaw or the cylinder base can have the mandrel-like attachment.
  • the hydraulic cylinder is designated 1. In its basic structure, it corresponds to the known rescue cylinders, as shown on page 8 of the aforementioned publication by the applicant.
  • the control valve 2 is located on the piston rod end of the hydraulic cylinder.
  • the clamping jaw 4 is fastened to the cylinder base 3. Opposite is the peeling jaw 5, which is fastened on a slide 6, which is acted upon by the piston rod 7 and is axially displaceable.
  • the carriage 6 is guided on the housing of the hydraulic cylinder 1 and has yet another attachment point 8 'for the peeling jaw 5, as shown in Figure 2.
  • a mandrel 9 is arranged on the carriage 6 for pressing in the first opening.
  • FIGS. 4 and 5 Another embodiment of a peeling device according to the invention is shown in FIGS. 4 and 5.
  • the hydraulic cylinder 1 with the control valve 2 and the cylinder base 3 has a peeling jaw 5 attached directly to the piston rod 7.
  • the clamping jaw 4 is fastened to the end of the cylinder housing on the piston rod side.
  • a further clamping jaw 10 is arranged on the cylinder base 3, which is used for the second stroke.
  • the actuation path of the peeling device can be almost doubled.
  • an extension of the actuation path can also be achieved by using an extension 11 which is plugged onto the piston rod 7 during the second stroke.
  • a mandrel 9 is attached to the cylinder base 3 and serves to press in the first opening.
  • FIG. 9 shows a peeling device according to the invention in use.
  • the wall into which a manhole is to be made is designated by 12. Sheet thicknesses up to 7 mm can be peeled.
  • the first opening 13 is made, for example by arranging the peeling device according to FIG. 8 with its mandrel 9 approximately perpendicular to the plane of the wall 12, the piston rod 7 being in contact supports an abutment (not shown). Now the hydraulic cylinder 1 is pressurized, the piston rod 7 extends and presses the mandrel 9 into the wall 12, whereby the first opening 13 is created. The mandrel or the piston rod is retracted again and the peeling device with the clamping jaw 4 and the peeling jaw 5 is suspended in the first opening 13.
  • the hydraulic cylinder is now pressurized again, whereby the piston rod 7 extends with the peeling jaw 5 and peels the sheet metal strip 14 out of the wall 12 (FIG. 9).
  • the piston rod is retracted again and the peeling device according to FIG. 6 with its further clamping jaw 10 is inserted into the first opening 13 and the slot that has already been created, and the hydraulic piston 1 is pressurized again, whereby the peeling jaw 5 peels further forward and extended the slot.
  • the piston rod 7 can be retracted in a third operation, the extension 11 plugged in and the slot can be extended even further with a further stroke.
  • the procedure is similar with a peeling device according to FIGS.
  • the peeling jaw is attached to the corresponding attachment points 8, 8 'on the slide 6 as required.
  • the mandrel for introducing the first opening 13 can also be arranged on the head of the slide 6, or combined with the peeling jaw can be designed as a plug-on set.
  • the maximum force of the hydraulic cylinder is available from the beginning over the entire piston stroke.
  • this has a spreading path at the tips of 820 mm when ready for operation Mass of 28 kg and a spreading force of 60 - 80 kN.
  • a peeling device with a (hydraulic cylinder type 12/300 achieves a maximum travel of at least 600 mm with an operational mass of 13.5 kg and a compressive force of 120 kN (first stroke 300 mm and + 2, stroke 300 mm) and when using an extension 11 up to 1000 mm can be achieved, ie a significant increase in performance with simultaneous weight reduction.
