Definitions

  • an overhead crane with a telescopic mast is used, the elementary drums of which develop towards the ground.
  • Such a device is used, for example, for aircraft maintenance, the operator being mounted on a cantilever platform or nacelle associated with the lower part of the last drum relative to which it can change orientation.
  • each barrel has a polygonal cross section with an even number of sides in order to determine lateral partitions whose external face of some of them, angularly distributed in regular manner, supports a guide cooperating with complementary elements carried by the internal face of the corresponding partition of the barrel which surrounds it and the other lateral partitions of which bear on the internal face of the pulleys for the passage of the auxiliary cables.
  • the barrels are produced by means of a tubular lattice frame with a hexagonal section, three partitions of each barrel not adjacent carrying the guides, while the pulleys are supported by the other three partitions.
  • an overhead crane 1 intended to move by means of wheels 2 supported on raceways 3, said overhead crane being provided with a carriage 4 suitable for moving transversely by means of wheels 5, relative to the main beam of the overhead crane.
  • the carriage 4 is secured to a telescopic mast 6 produced by means of a number of drums sliding one inside the other.
  • the chassis of the carriage 4 is associated with a fixed barrel 7 in which a first barrel 8 can slide, which encloses a second barrel 9 in which an extreme barrel 10 can move, the lower end of which is secured to a platform or nacelle 11.
  • the barrel 10 is secured to a slewing ring 11a which cooperates with a pinion 12 driven by a geared motor 13 for rotating the platform or platforms relative to the shank 10.
  • auxiliary cables 14 the ends of which are attached to the upper end on the one hand of any barrel and on the other hand of that of the barrel located at the outside of the one around him directly.
  • one end 14a of the cable 14 is attached to the carriage 4, and the cable passes around a pulley 15 carried by the interior of the barrel 8 located immediately inside of 7, then the other end 14 b of the cable is attached above the drum 9 located in the 8.
  • a second cable 16 is attached by one of its ends 16a to the upper end of the shaft 8, then it passes around 'A pulley 17 associated with the barrel 9, its other end 16b being fixed to the upper end of the last barrel 10.
  • each barrel has in cross section the shape of a hexagon, so that there are three cables 14 and three cables 16 located opposite three non-adjacent faces and angularly distributed so regular with respect to the geometrical axis barrel stick.
  • the other three faces of the latter are intended for their angular guidance.
  • the partitions of the drums which are not arranged opposite the pulleys 15 and 17, that is to say those which are placed between the three aforementioned faces carry on their outer walls a guide rail 18.
  • These rails are respectively carried by the drums 8, 9 and 10 (fig. 2).
  • the internal walls of the corresponding partitions of the drums 7, 8 and 9 carry two superimposed rows of rollers 19 which roll on the rails 18.
  • the deployment of the drums is carried out by gravity.
  • Main cables 20 leave from a winch 4 a from the carriage 4 to come to cooperate with pulleys 21 mounted at the top of the barrel 10, in order to control the speed of movement synchronized by gravity of said barrels.
  • the main cables 20 are wound in the known manner so as to reassemble the barrel 10 which, via the cables 16 and 14, ensures the synchronized movement of the barrels upwards. We will not return to this way of proceeding which is well known in practice.
  • each box 22 is produced by means of two tubes of rectangular or similar section 23 a , 23 b oriented obliquely and joined by means of two sheets, one internal 23 c and the other external 23 d .
  • the outer faces of the drums can be coated with solid panels illustrated more particularly in FIG. 3.
  • a telescopic mast for an overhead crane has thus been produced which has a structure capable of absorbing the forces due to the rotation of the platform by means of a guide on three rails fixed to the faces of a tubular lattice frame allowing significant weight gain, said guide also ensuring the resumption of bending forces when the nacelle 11 is mounted cantilevered.
