Definitions

  • the present invention relates to an electric winch or hoist.
  • Electric hoists or electric winches are usually constituted by a drum which has a horizontal axis and on which a cable winds. One end of the cable is fixed to the drum.
  • the drum is driven by a directly coupled electric motor which forms a monolithic unit therewith.
  • the hoist is usually suspended and used to lift loads by winding the cable on the drum.
  • Uneven winding of the cable can also cause jerking motions during the lifting and lowering of the load, consequently entailing discomfort and danger for users.
  • winches for cranes, hoisting towers, elevators, etc. which in order to obviate this drawback have a drum which is turned and grooved in a helical shape, so as to receive a cable having an exact diameter within the groove.
  • This type of structure of course entails a high cost for manufacturing the drum and in any case it is not suitable, from the functional point of view, for hoists, since the load can move the cable transversely to the point that the cable is still prevented from entering the helical groove. Furthermore, in hoists the cable is usually wound in multiple layers and accordingly the second layer would not have a guide with grooves except for the underlying layer of cable.
  • the aim of the present invention is to provide a hoist that obviates the cited inconveniences of conventional hoists.
  • An object of the invention is to provide a hoist with which the cable is wound on the drum uniformly in a helical pattern, without overlapping.
  • a further object of the invention is to provide a hoist which has a simple and reliable construction.
  • a hoist comprising a base body adapted to support a motor and a winding drum, the motor being adapted to drive the drum to wind a cable or the like; characterized in that at least the drum is mounted so that it can slide freely axially with respect to the body, so as to allow the uniform winding of the cable on the drum.
  • the hoist according to the invention includes a base body constituted by a base plate 3 slidingly associated with a fixed support constituted by a bar 5 which is advantageously tubular with a square cross-section.
  • the plate 3 supports an electric motor 7 driving a winder drum 9, in a per se known manner.
  • the winder drum 9 is adapted to wind a cable 11 in which one end (not shown) is fixed to the drum and the other end is provided with a hook or the like, in a per se known manner, in order to lift a load.
  • the plate 3 is associated with the bar 5 by virtue of omega-shaped members 13 which allow the free axial sliding of the plate-drum assembly with respect to the fixed support constituted by the bar 5.
  • Each omega-shaped member includes a pair of L-shaped members 15 which are fixed to the plate 3 by means of shock-absorbing members 17 which are constituted for example by a bolt 19 with an interposed elastic member 21.
  • the L-shaped members 15 support a bearing 23 adapted to slide on the bar 5.
  • the bar 5, in the illustrated case, has a square cross-section so as to have a horizontal upper supporting surface for the bearings 23, but might of course have any other cross-section suitable to allow the support and sliding of the omega-shaped members 13.
  • the hoist according to the invention also comprises a cable guiding member 25 which is rigidly coupled, at least in an axial direction, to the fixed support.
  • the cable guiding member 25 includes an elongated bar which is fixed to the bar 5 and has a guiding member which is constituted, in the illustrated case, by a pair of wheels or pulleys 29 adapted to slidingly receive the cable 11.
  • the operation of the hoist according to the invention is substantially similar to the operation of a conventional electric hoist, except that during the winding or unwinding of the cable on the drum, the drum can freely axially move with respect to the thread guiding member, allowing the cable to wind uniformly on the drum, one turn next to the other, even when the cable is diverted from the optimum direction for winding on the drum, as shown in dashed lines in Figure 1.
  • the hoist according to the invention is also suitable for different uses, for example as a winch for motor vehicles.
  • Motor vehicle winches too, have the problem of uneven winding of the cable on the drum due to the less than optimum direction of the loaded cable with respect to the drum.
  • the materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
