Definitions

  • the present invention relates to a tool which has been specially designed for the collection of ferrous metals, in particular in the cases where the collection must be carried out on pieces or residues of very different sizes, from pieces of considerable size, up to '' at the simple turn of iron, or in the case of small parts or cuts.
  • the tool recommended by this invention has been designed to solve the problem and give full satisfaction in the two cases mentioned above, by ensuring on the one hand a total collection of ferrous metals, whether large or small parts , whatever the size, and on the other hand avoiding entraining particles of earth, that is to say, in conditions of integrity cleaning for the metal.
  • the tool here recommended has a structure similar to that of a conventional hydraulic spider, that is to say that it is provided with a central body endowed with means of assembly to the crane of corresponding control, central body to which are articulated a multitude of arms or radial shovels allowing the acceleration of the conventional mechanical pickup operation, but with the singular characteristic that the already mentioned central body materializes in a powerful electromagnet so that all these metal parts which by their small size can escape the multiple jaw of the tool, entering the magnetic field of the electromagnet, are automatically attached to the central body of the tool in question.
  • the electromagnet already mentioned includes several magnetic cores, arranged concentrically, to obtain a homogeneous field over the entire surface of the tool, which ensures better operation from the point of view magnetic with less energy consumption.
  • the larger metal parts undergo a double mechanical and magnetic fixing, which results in the tool offering better safety in transport, that is to say during the lifting of the crane which actuates the tool. .
  • the tool will operate from an electromagnetic point of view with autonomous character, at the expense of a 24-volt battery, but this tool could also be adapted to any other power source.
  • the tool here recommended has a structure which consists of a central body (1), provided in its upper end with means of attachment to the corresponding lift wheel, such as for example the fork (2), while in its end lower there is a discoidal expansion (3) provided with pairs of small ears (4) in radial arrangement, or are articulated the central body, by means of pins (5), the respective rocking arms or shovels (6), actuated hydraulically by means of cylinders (7) which extend between small connecting rods (8) articulated on the arm and on the periphery of the discoidal expansion of the body, and has pairs of small ears (9) established at the upper end of the central body in question.
  • the discoidal and lower expansion (3) of the body constitutes in addition and in accordance with another of the characteristics of this invention, the carcase which contains a powerful electromagnet (10), so that the tool achieves a double function , of a hidromechanical dimension and of another electromagnetic one, ensuring in this way the collection of all ferrous metals, as small as they are and without entraining earth, since this one is not attracted by the magnetic field of the electromagnet.
  • the electromagnet (10) consists of multiple cores, to thereby obtain better uniformity of the magnetic field over the entire surface of the discoidal expansion (3) of the central body of the tool, which is equivalent to better adhesion for small metal parts as well as less consumption of the electro -magnet.
