Definitions

  • the present invention is included in the field of devices or tools for collecting ferrous materials, which are coupled to the hook of lifting equipment, such as cranes, vehicle cranes, overhead cranes, winches, derricks, hoists, etc.
  • the invention relates to a rotation mechanism, which allows the ferrous material collection device to be rotated 360 ° both in one direction and the other, without there being any risk of cutting the cables that power the electromagnet plant of said device and causing detachment of the load. Also object of the invention is a ferrous material collection device that includes said rotation mechanism.
  • German Utility Model No. 20 2012 100579 explains a gripping device comprising a base, claws, cylinders, and an electromagnetic disc. At least two claws are pivotally coupled to the base.
  • the base is provided with a coupling portion, which can be pivotally coupled to an arm of an operating machine.
  • Each claw is pivotally coupled to a first location on a vertical base plate.
  • Each cylinder is pivotally coupled to one of the claws.
  • US Patent No. 6,168,219 explains a clamp that includes a ferrous body with a plurality of prongs pivotally connected thereto.
  • a magnetic coil is arranged inside the ferrous body. When the magnetic coil is activated, it creates a magnetic field within the area defined by the prongs.
  • the prongs are also magnetised by the field. Additional magnetic coils can be added to one or more prongs.
  • a lifting equipment holding arm fastened to an electromagnet plate that can comprise a plurality of auxiliary articulated arms in the form of radial blades for holding, during lifting and transport, the ferromagnetic material previously attracted by the electromagnet plate.
  • Radial blades are usually actuated by hydraulic cylinders.
  • These additionally known devices or tools for collecting ferrous metals usually comprise a rotation mechanism that allows rotating said device around its vertical axis, thus facilitating the placement of the load, that is, the ferrous material objects that it transports.
  • These rotation mechanisms usually comprise an electrical collector-connector assembly, which allows the continuity of the electrical supply to the electromagnet plate of the device during the 360 ° rotation both in one direction and in the other. That is, the device can be rotated to one side or the other without there being any risk of cutting the cables that power the electromagnet plant of said device and causing detachment of the load.
  • the existence of any solution in the state of the art that shows a combination of characteristics similar to that presented by the rotation mechanism object of the invention recommended here is unknown.
  • An object of the invention is a rotation mechanism for a ferrous material collection device, which comprises:
  • connection means comprise a collector and a connector in permanent contact with the collector, so that an electrical connection between the first and second cables is ensured in any relative position between the fixed part and the mobile part.
  • the fixed part comprises an upper section and a lower section connected to each other through a tubular element, and for its part, the mobile part is traversed by the tubular element, so that said mobile part is arranged between the upper section and lower section of the fixed part.
  • An object of the invention is also a ferrous material collection device that comprises the rotation mechanism mentioned above.
  • the present invention relates to a rotation mechanism for a ferrous material collection device, as well as a ferrous material collection device including said rotation mechanism.
  • the rotation mechanism object of the present invention comprises:
  • connection means (3) comprise a collector (3.1) and a connector (3.2) in permanent contact with the collector (3.1), so that an electrical connection between the first and second cables (4, 5) is ensured in any relative position between the fixed part (1) and the mobile part (2) .
  • the fixed part (1) comprises an upper section (1.1) and a lower section (1.2) integrally connected to each other through a tubular element (1.3), and for its part, the mobile part (2) it is traversed by the tubular element (1.3) so that said mobile part (2) is arranged between the upper section (1.1) and the lower section (1.2) of the fixed part (1), the mobile part (2) being able to rotate to one side or the other, in the horizontal plane, around the vertical axis (longitudinal plane (1)) of the rotation mechanism that forms the tubular element (1.3), while both upper and lower sections (1.1, 1.2) of the fixed part (1) remain immobile or static.
  • the collector (3.1) is arranged in the lower section (1.2) of the fixed part (1), while the connector (3.2) is arranged at a lower end (2.1) of the mobile part (2), so that, in use, the connector (3.2) is configured to slide on the collector (3.1) during the rotation of the mobile part (2) with respect to the fixed part (1).
  • the lower section (1.2) of the fixed part (1) could form a track-holder and the collector (3.1) could be respective copper tracks or rings, supported by the track-holder, in electrical connection with the first cables (4); for its part, the lower end (2.1) of the mobile part (2) could form at least one brush-holder, arranged facing the track-holder laterally, and the connector (3.2) could be respective brushes, supported by the brush-holder, in electrical connection with the second cables (5).
  • the upper section (1.1) of the fixed part (1) is fastened from below to a flange (6) with lugs (6.1), for example, screwed to the flange (6), or using any other fastening means known to be suitable for carrying out said fastening between the two pieces or elements (1.1, 6).
  • Said lugs (6.1) being adapted to be fastened to the hoisting equipment.
  • an upper end (2.2) of the mobile part (2) can be adapted to be fastened to the ferrous material collection device to which the rotation mechanism is coupled.
  • the first cables (4) could be two two-phase power supply cables, coming from an electric generator (not shown in the figures), and advantageously arranged inside the tubular element (1.3), so that they electrically connect the copper tracks or rings of the collector (3.1) to respective power supply outputs of said electric generator.
  • these could be two connection cables to an electromagnet plate (7) of the ferrous material collection device to which the rotation mechanism is coupled, such as the one shown in Figure 2 or the one shown in Figure 3 , so that said second cables (5) electrically connect the brushes of the connector (3.2) to respective power supply inputs of said electromagnet plate (7).
  • the proposed rotation mechanism allows the continuity of the electrical supply to the electromagnet plate (7) of the device during its rotation to one side or the other, without there being any risk of the first and second cables (4, 5), which power the electromagnet plate (7), being cut and the load being detached.
  • a possible embodiment of the ferrous material collection device also object of the present invention can be based on an electromagnet plate (7), which, in turn, can comprise a tubular upper projection (7.1) adapted to be fastened to the outside of the upper end (2.2) of the mobile part (2) of the rotation mechanism.
