Definitions

  • Load lifting magnet which is adjustable in height on a suspension is suspended and to hold magnetizable (Ferromagnetic) material in one place and to it Transport from one place to another and its dropping serves in the other place.
  • Such pliers need to be lifted on both sides Workpiece a certain swivel range or range of motion, which is not available everywhere, so that when loading for example slabs from a ship onto a truck there are corresponding difficulties, which often do not are overcome.
  • Round magnets are generally used to lift scrap and also in the form of a permanent magnet or Electromagnet.
  • rectangular magnets are known, which also can be designed as a permanent magnet or as an electromagnet. These magnets are used when using two magnets or several magnets used to lift ferromagnetic Plates, slabs, billets, pipes and the like.
  • a magnetic crane is essential when it comes to lifting, moving and transporting heavy goods. In many technical versions this hoist is used in a wide variety of industries used. In companies producing steel, steel processing and the steel trade, a crane variant plays a special one Role, namely the magnetic crane.
  • Magnetic cranes are used, for example, for lifting and transporting of sheets, slabs, sheet packages, sheet and wire coils, profiles, Sticks, rails and pipes are used. But also the envelope of scrap packages, larger scrap parts and loose scrap is possible with them.
  • the loads are lifted by simple Placing on the material, which, depending on the type, individually, in bundles, Parcels or layers can be lifted. With a magnetic crane the material can also be turned, dosed and picked become. And it is also possible to use sheet metal, shaped steel, billets and the like to put them directly on top of one another and stack them.
  • the object of the invention is to overcome these difficulties fix and a lifting magnet with a holding device such to provide that the holding device the task of a pair of pliers an underload gripper takes over, but their swivel ranges too neither side needed.
  • This object is achieved in that at both Ends of the magnet housing one perpendicular to the magnet housing Oriented spindle is provided, along which a swivel arm height-adjustable with a gripper attached to the other end is arranged.
  • the object underlying the invention is according to a secondary Invention ideas also solved in that Transport of non-magnetizable (non-ferromagnetic) Material of the lifting magnet can be used.
  • the gripper arms reach under the load to prevent the load from falling prevent.
  • the safety grippers can also be used without an activated magnet are used as load grabs or load suspension devices, the magnet only serves as a static connection frame. It can handle both ferromagnetic and non-magnetic loads be lifted.
  • the lifting magnet designed according to the invention it is possible to find the latter in gorges of e.g. 300 mm wide.
  • the swivel arms are expediently pivotable up to about 230 °.
  • the gripper arms are in front of the load with the magnet raised and swiveled inwards. You are over the load and do not expand wider than the magnet width. After lifting the load with the magnet, they swivel Swivel arms so far that they can be lowered fit past the load. Then the swivel arms swivel in until they touch the load material. Then the Swivel arms raised so that the brackets are positive to reach under the burden. All movements can be from Can be driven manually, by electric motor or hydraulically. It loads with widths of e.g. 100 to 2,000 mm.
  • the magnet can be used both horizontally and lengthways be placed on the material, with full functionality the gripper.
  • a lifting magnet with one in the drawing solenoid, not shown in detail in a magnet housing 10, which is adjustable in height (on a hoist) is and for receiving magnetizable material from the a location and for its transportation from one location to another serves another place and its dropping in the other place.
  • a crossbar 13 with on both sides of the crossbar 13 arranged holding pieces 14, 15 are provided.
  • spindles 16, 17 are provided with their lower ones Ends 18, 19 attached to both sides of the magnet housing 10 are.
  • Adjusting nuts 20, 21 are provided on the spindles 16, 17, on which swivel arms 22,23 with the external thread of the spindles 16,17 matching internal thread are arranged adjustable in height.
  • Grippers 24, 25 are provided at the outer end of the swivel arms 22, 23. which have brackets 26, 27 at their lower end.
  • a drive 28 is provided, which is via a transmission 29 allowed to drive the adjusting nuts 20, 21.
  • FIG. 3 shows a slab 30 against which the grippers 24, 25 fit tightly and under which the brackets 26, 27 engage. In In this working state, lifting, transporting and lowering take place the slab 30.
