Definitions

  • the load is supported by a number of assemblies, each of which can be removed from the load when this has been moved into the required position.
  • Each assembly has means, operated by an electric motor, for raising or lowering a load-engagingpart relative to a ground engaging part, and these motors can all be controlled by a single control system to effect smooth handling of the load.
  • This invention relates to load-handling appliances which may be used for example, for loading a container into an aircraft hold.
  • Some existing load-handling appliances comprise a series of mobile assemblies adapted to be secured to the corners of the load to be shifted.
  • Each such mobile assembly includes a bracket which can both swivel about a vertical axle fixed to the load and slide along this axle, and a sleeve adapted to pivot in relation to said bracket, a support member being slidably mounted in said sleeve and being fast with a rack bar engaging with a worm the axle of which is supported by the sleeve.
  • the aim of the present invention is to provide an improvement in load-handling appliances ofthe foregoing type which will obviate this drawback.
  • a load-handling appliance comprises a plurality of mobile assemblies adapted to be secured to the load. each assembly including:
  • each of the supporting legs is raised or lowered by simply actuating a push-button so that it is very easy to raise or lower all of them simultaneously and thus keep the load perfectly horizontal.
  • the worm can be located very close to the support member carrying the rack bar. This member preventing the motor speed-reducing assembly from being positioned along the axis of the worm. It would be possible to mount the motor speed-reducing assembly obliquely relatively to this worm and connect the latter to the output shaft of the assembly by means of a Cardan joint; equally it would be possible to locate the assembly alongside the worm and connect the latter to the output shaft of the assembly by means of an oblique shaft and two Cardan joints. However use of the Cardan joint or joints entails a transmission power loss.
  • the motor speed-reducer assembly can be pivotably mounted by means of an eccentric collar, coaxial with the axis of the joint between the bracket and the sleeve; the clearance can be adjusted by rotating this collar so that there is no frictional contact between the speed reducer casing and the support member.
  • the output shaft of the speed reducer can also be connected to the worm by means of a coupling sleeve fixed to one only of these members, for example to the output shaft, and the upper part of the pivotable mounting of the motor speed-reducer assembly includes an extension upon which the eccentric collar is slidably mounted and which is equipped with means for locking the collar in its upper position; said means consisting for example of a pin fixed diametrally across the pivot pin of the pivotable mounting and adapted to pass through two longitudinal grooves in the eccentric collar when the latter is rotated into the appropriate position.
  • FIG. 1 is an elevational view of a container equipped with the load-handling appliance according to the invention
  • FIG. 2 is a view of a detail on a larger scale
  • FIG. 3 is a view from below of the eccentric collar.
  • FIG. 1 shows a container 1 at each corner of which is located a mobile assembly designated generally by the reference numeral 2.
  • Each assembly 2 consists of a bracket 3 adapted to pivot around an axle 4 which is fixed to the container 1 by lugs 5, said bracket also being adapted to slide over said axle; pins 6 enable the bracket 3 to be fixed in the bottom position shown in drawing.
  • a worm 13 mounted on the arm 10, engages with a rack bar 14 integral with the tubular support 8.
  • the container 1 In order to load the container 1 into the hold of an aircraft for example, it is brought near the hold on its wheels 9.
  • the pins 6 are withdrawn from one of the two brackets 3 adjacent to the hold so as to raise this bracket, the height of the tubular support being adjusted relatively to the bracket by rotating the worm 13 so that the wheel thereof is level with the floor of the hold, the bracket of the wheel 9 of which thus comes to rest on the floor of the hold, is lowered towards the interior of the hold.
  • each of the worms 13 is connected by a coupling sleeve 15 to the output shaft 16 of a speed reducer 17; the sleeve is fixed by a screw 15a to the shaft 16.
  • the input shaft of this speed reducer is coupled to the shaft of an electric motor 18 the axis of which is shown at 18a; it will be seen that this axis is offset laterally relatively to the axis of the shaft 16 and of the worm 13.
  • the speed reducer 17 is fast with a clamp 19 which is mounted on an eccentric bearing 20a of a collar 20 and is secured to this collar by means of a screw 21 engaging in a channel 20b of said bearing.
  • the collar 20 itself is mounted on an upwardly extending rod 22 the enlarged head 22a of which is welded to a small plate 23 secured by screws 24 to a skirt member 25. This latter is fixed to the bracket 3 so that the rod 22 is coaxial with the axis 12.
  • the collar 20 is rotated so that when the bracket is in its lowermost position relative to the support 8, the part of the casing of the speed reducer 17 which is coaxial with the worm does not rub against the rack bar 14, this collar being thereupon fixed in position by tightening the screw 21.
  • the collar 20 includes two internal longitudinal grooves 200 and two projecting pins 26a and 26b are fixed laterally and diametrally in the rod 22 and are angled in relation to one another; the length of these pins being substantially equal to the spacing apart of the extremities of the respective grooves 20c.
  • the motor and speed reducing assembly 17-18 is to be disengaged from the worm 13, it is merely neces sary, after having slackened off the screw 21, to raise said assembly until the worm axle comes clear from the coupling sleeve 15.
  • the collar 20 is rotated until the projecting ends of the pin 260 can be passed through the grooves 20c, the collar being then rotated again. Accordingly, the collar comes to rest on the pin 26a thus preventing the speed reducing assembly from being lowered.
  • the collar is turned so as to enable the projecting ends of the pin 26b to pass through the grooves 200.
  • the motor 18 is connected to a push-button control panel through a cable 27. Having all the control panels to hand, one operator is able to control simultaneously all the motors 18, which ensures that the load can be raised and lowered while in a perfectly horizontal position.
  • Load-handling appliance comprising a plurality of mobile assemblies adapted to be secured to the load, each assembly including:
  • pivot means mounted on said bracket and supporting said eccentric collar for pivotal movement about an axis which is coaxial with the pivotal axis of the sleeve relative to the brackets, and
  • said pivot means including an extension upon which said eccentric collar is slidably mounted, said extension including means for locking the collar in an upper and lower position thereof on said extension.
  • said means for locking the collar comprises a pin fixed diametrally across the pivot means and adapted to pass through two longitudinal grooves provided in the eccentric collar when the collar is rotated into position in which the pin is aligned with said grooves.
