Definitions

  • This invention relates to a hoist, in other words to a device to lift or lower charges or for pulling loads by means of a cable being guided over a driving pulley.
  • the invention particularly relates to a hoist of the type where one driving pulley is formed by two combined pulley halves forming together a cable groove.
  • the first aim of the present invention is to provide for a hoist where the said disadvantage is systematically avoided. More generally still the invention is intended to provide for a hoist offering the combination of the following favourable characteristics: - a uniform pressure on the cable over the entire angle of contact, mainly by using pulley halves being in a parallel position with each other; - an easy, automatic cabling of the device after the cable end has been presented to it; - the cable remains in its correct position between the two pulley halves under all circumstances, in other words is not tending to move away radially from the centre of the cable pulley.
  • the invention consists of a hoist characterized in that it mainly consists of the combination of a driving pulley, consisting of two pulley halves; elastic means axially pressing the two pulley halves together; a by means of the two pulley halves formed cable groove having, at least in the area where the cable is gripped, parallel flank parts and small cable guide wheels, working together, more particularly over the angle of contact.
  • the hoist according to the invention mainly consists of a driving pulley 1 consisting of two parallel pulley halves 2 and 3; elastic means 4 pressing the pulley halves 2 and 3 axially together; a cable groove 5 formed by the two pulley halves and a number of small cable guiding wheels 6 along the outer circumference of the cable groove 5.
  • the pulley half 2 is mounted rotatably with respect to the casing 9 by means of bearings 7 and 8.
  • the second pulley half 3 is held in place with respect to the first half 2 by means of a number of bolts 10, supporting at the same time the aforementioned elastic means 4.
  • the elastic means 4 axially pressing the pulley halves 2 and 3 together may consist of springs chosen at random such as Belleville springs, helical springs, etc. It is noted that the tension of the springs is determined by the force to be exerted on the cable 11, in such a way that is not deformed on the one hand and there will be sufficient friction to have the charges lifted by the hoist without any danger of slipping on the other hand.
  • a remarkable characteristic of the invention lies in the fact that a combination is provided for where the two pulley halves 2 and 3 are parallel, while the cable groove 5 formed by the pulley halves 2 and 3 in the area where the cable is gripped will have parallel flank parts 12 and 13, as is shown more specifically in figure 3.
  • an other particular characteristic of the invention consists in the fact that this cable groove 5 over its angle of contact presents inclined flank parts 14 and 15 fitting with the parallel flank parts 12 and 13 and forming a V-shaped part.
  • the inclining flank parts 14 and 15 will make an angle A with the main plane of cable pulley 1, being 12,5 degrees.
  • the pulley halves 2 and 3 may be provided with roundings 16 and 17.
  • the aforementioned small cable guiding wheels 6 are, as shown in figure 2, mainly situated along the entire circumference of the cable groove 5. They preferably consist of bearings, mounted on small shafts 18, fixed in casing 9.
  • one small cable guiding wheel 6A will be used near the area 19 where the free end 20 of the cable 11 is introduced respectively leaves, having a larger diameter than the other small cable guiding wheels 6. The advantage of it will be explained hereafter.
  • the hoist is driven preferably by means of a driving shaft 21 and an external toothing 22; planetary gears 23 situated round the driving shaft 21 and working together with it; and a bush 24 fixed to the driving pulley 1, meshing with the planetary gears 23 by means of an external toothing 25.
  • the shaft 21 may be driven either manually by means of a crank or similar device, or automatically for instance by an electric motor either fixed to the aforementioned casing 9 or not.
  • the use of the aforementioned planetary linking mainly has the advantage that the hoist wil be particularly compact.
  • the small cable guiding wheels 6 don't exert any pressure on the cable 11 during normal use of the hoist.
  • the small cable guiding wheel 6A near the area 19 where the cable is introduced or leaves the device will exert a certain pressure on the cable 11, in order to keep it down in the cable groove 5.
  • the small cable guiding wheel 6A may be mounted fixed, while according to a second possibility it may be pushed in the direction of the cable pulley 1, by means of springs or similar, not shown on the drawing.
