Definitions

  • the invention relates to a device for emptying to be scrapped. Liquid and / or gas-absorbing hollow bodies.
  • Hollow bodies of the type mentioned above often still contain considerable residual amounts of fuel or other explosive liquids or gases.
  • shredder systems hammer breakers
  • residues When crushing such scrap pieces in so-called shredder systems (hammer breakers), such residues then form an explosive mixture with the atmospheric oxygen, which is ignited by flying sparks during the metal crushing process and causes dangerous explosions.
  • shredder systems hammer breakers
  • the invention has for its object a mechanical device for emptying liquid and / or gas creating hollow bodies that can be operated from a safe distance or from an explosion-proof cabin.
  • this device is characterized by two mutually opposite, relatively movable jaws, of which at least one jaw carries at least one mandrel, at least temporarily protruding into the space between the jaws, for perforating the hollow body.
  • the jaws clamp the hollow body to be emptied between them, whereby at the same time or following the clamping of the mandrel or thorns are preferably pushed through the hollow body and pulled out again, so that liquid and / or gases contained in the hollow body can escape.
  • each mandrel is under the influence of an overload safety device that limits the mandrel path. This measure prevents breakage of the mandrel or destruction of the device when one or more mandrels hit an impenetrable obstacle, since the mandrels braked in this way no longer participate in the further movement of the jaw or jaws.
  • the mandrels are expediently driven by means of a hydraulic cylinder each attached to the associated jaws.
  • a hydraulic drive offers the advantageous option of installing a pressure relief valve in the pressure feed line of the hydraulic cylinder as an overload protection device. If one of the mandrels encounters excessive resistance, the pressure in the associated hydraulic cylinder increases up to the response pressure of the pressure relief valve. The latter then opens and injects hydraulic in a known manner liquid into the hydraulic tank, so that the affected mandrel remains in front of the resistance, while the other mandrels continue to penetrate the hollow body.
  • the mandrels are advantageously connected to the associated hydraulic cylinder so that they are designed as an extension of the piston rod of the hydraulic cylinder.
  • the jaws carrying the mandrels can simultaneously be the drive element of the mandrels. This presupposes that the mandrels protrude from the working surface of the jaw by the maximum required working length of the mandrels and join the advancing movement of the jaw against the hollow body to be perforated.
  • the mandrels are not absolutely rigidly connected to the associated jaws, but are in turn connected to an overload protection.
  • the mandrel ends facing away from the space between the jaws are each advantageously designed as a piston rod of a gas pressure spring attached to the jaws supporting the mandrels.
  • gas pressure springs are set in a known manner so that the pressure medium is compressed in the event of an overload or is displaced into a pressure accumulator, so that, in contrast to the other mandrels, the mandrel encountered with an excessively high resistance does not advance further.
  • a first jaw 1 is stationary with several feet 2 on a foundation 3.
  • a second jaw 4 is on the side Columns 5, only one of which is shown, guided up and down.
  • the columns 5 are each formed with a piston rod 6 as a hydraulic cylinder.
  • the piston rods 6 are fastened to a support rod 7, 8 which is firmly connected to the jaw 4.
  • the jaw 4 can be moved up and down by means of the hydraulic cylinders 5, 6 in order to firmly clamp the hollow body to be perforated, for example a fuel tank 9 or the old car 10 containing it, against the stationary jaw 1.
  • a plurality of hydraulic cylinders 11, 12 are fastened on the jaw 4. Behind these hydraulic cylinders, further identical hydraulic cylinders with the same function described below can be arranged on the jaw 4. More than two such hydraulic cylinders can also be placed side by side.
  • the piston rods 11a, 12a of the hydraulic cylinders 11, 12 carry pointed mandrels 13, 14. The latter have been inserted in the example 15 into the space 15 between the jaws 1 and 4 and have pierced the fuel tank 9, so that the fuel when the mandrels 13 are withdrawn , 14 expires.
  • the spilled fuel passes through bores 16 in the jaw 1 into a collecting trough 17 located under the jaw 1 in order to from there, e.g. to be removed for further use.
  • On the jaw 4 is a hydraulic unit 18 constructed in a known manner, which essentially contains the following operating elements, not shown.
  • the columns 5, which are designed as hydraulic cylinders, are hydraulically acted upon by the hydraulic unit 18 for adjusting the jaw 4.
  • a pressure relief valve 23, 24 is arranged, which, when a preset working pressure in the associated hydraulic cylinder is exceeded, either shuts off the working pressure line 19 or 20 or switches over a line 25, 26 to return to the tank. This causes the associated hydraulic cylinder 11 or 12 to be relieved of pressure when a mandrel strikes a very resistant obstacle, so that the mandrel stops or can even be pushed back, thereby avoiding damage to the device.
  • the device described above can also be operated with the mandrels constantly extended.
  • the jaws 4 must then be raised so far that the hollow body 10 to be perforated can be placed under the mandrels 13, 14.
  • the jaw 4 is lowered by means of its hydraulic cylinders 5, 6 when the working pressure lines 19, 20 and filled hydraulic cylinders 11, 12 are closed, the spikes penetrating into the hollow body, perforating the tank 9 and, if desired, the old car 10 also being compressed by means of the jaw 4 .
  • the mandrels 13, 14 are aligned with the bores 16 in the jaw 1, so that if the jaw 4 is lowered somewhat too much, they cannot rest on the jaw 1.
