Definitions

  • the invention relates to brackets for rack winches of a lifting and lowering device for transportable large containers or the like, wherein the toothed racks of the winches are arranged on support legs for the large container and the outriggers are to be fastened to connecting bars on the corners of the large container, and the brackets furthermore viewed from above, have at one end a U-shaped mounting space for a suitable mounting of a connecting bar and at the other end a U-shaped guide space for a support leg with a rack.
  • the large containers can be containers, shelters or cabins, for example.
  • the device is also suitable for lifting, depositing or supporting building stalls or the like.
  • a boom of the above type is known from German utility model 82 35 609.
  • This relatively short boom consists of two plates with a C-shaped cross-section open to the outside, which are attached to a spacer arranged between them.
  • the winch gear is fastened to the outside of one plate, the drive pinion of which projects into the guide space at one end of the boom and is in engagement with the toothed rack on the support leg. Due to the fixed winch gear, this boom has a relatively high weight, which would increase unacceptably with larger boom lengths, such as those required when loading large containers in transport aircraft. It should be emphasized that after use of the lifting and depositing device it should be possible to disassemble it into individual parts with a relatively low unit weight, so that these parts can be carried and stowed relatively easily.
  • a lifting or lowering device for transportable large containers is also known, in which booms are used, to which the winch gear is detachably fastened by means of plug bolts, so that after the use of the lifting and lowering device has ended the jibs can be removed.
  • the arms of this known device are not suitable for attachment to connecting bars on the container side.
  • the invention has for its object to develop a boom of the type described in such a way that it has a relatively low weight even with a relatively long length and is therefore easy to manipulate.
  • this boom Due to the shape of the wrench, this boom has a relatively narrow, weight-saving middle section and, in conjunction with the flat design, a piece weight that is acceptable for manipulation is achieved after removing the winch gear. It is also important that the boom can be manufactured practically without losing the above advantages in a longer length, as is required when loading large containers in transport aircraft.
  • a preferred embodiment of the invention is characterized in that the maximum overall height of the boom on its connection side is Y ⁇ 0.8 ⁇ X, X being the length of the boom from its connection-side end to an inside of the U-shaped guide space for a support leg with rack.
  • Yet another embodiment of the invention which increases the possible uses of the boom and thus the entire device, is characterized in that the mounting space and the guide space, viewed from above, are arranged at right angles.
  • the large container 10 to be lifted or set down or supported at a distance from the floor has a rectangular outline and has standard corner fittings 11 on its four corners at the top and bottom, to each of which a connecting bar 12 is detachably fastened.
  • the connecting bars 12 consist of tubes with, for example, a square cross-section (see FIGS. 2 and 3).
  • a rectangular, round or polygonal one, e.g. Hexagonal cross-section is possible.
  • the lifting and depositing device for the large container 10 has four rack winches 13 in particular, which can be detachably connected to the connecting bars 12 via brackets 14.
  • Each arm 14 consists, for example, of a cast part in the form of an oversized wrench.
  • the arms 14, viewed from above, have a fork-shaped connecting part 15 with a U-shaped attachment space 16, with which the arm 14 can be fitted onto a connecting bar 12 and can be detachably fixed to the spar by means of two plug bolts 17.
  • the socket pins 17 extend through corresponding bores in the spar 12 and in the fork-shaped connecting part 15.
  • the fork-shaped connecting part 15 tapers towards the center and merges into a relatively narrow central part 18, which has at its outer end a further fork-shaped part 19 with a U-shaped guide space 20 for a support leg 21 carries.
  • a toothed rack 22 is secured axially parallel, which engages in a drive pinion (not shown) of a winch gear 23, which can be actuated by a hand crank 24.
  • the winch gear 23 is detachably installed in a part of the U-shaped guide space 20 by means of two plug pins 25 and closes it off from the outside, whereby the support leg 21 consisting of a square tube is guided on all sides.
  • the plug pins 25 extend through bores, not shown, in the fork-shaped part 19 and in the gear housing.
  • the boom 14 ⁇ shown in FIG. 3 in plan view corresponds essentially to that according to FIGS. 1 and 2 with the exception that the fork-shaped part 19 ⁇ with its guide space 20 ⁇ for a support leg 21 at right angles to the fork-shaped part 15 and the mounting space 16 is arranged.
  • two winch gearboxes 23 are connected in a drive manner so that only one hand crank 24 has to be turned for their actuation.
  • the boom 14 or 14 ⁇ are very flat, in the embodiment of FIG. I their greatest height Y on the fork-shaped connecting part 15 only slightly exceeds the height H of the winch gear 23.
  • the greatest overall height Y of the boom 14 or 14 ⁇ is: Y ⁇ 0.8 ⁇ X.
  • X means the length the boom 14 or 14 ⁇ from its connection-side end to an inside 26 or 26 ⁇ of the U-shaped guide space 20 or 20 ⁇ .
  • the booms 14 and 14 ⁇ are particularly suitable for lifting and depositing devices which are used for loading large containers 10 in transport aircraft.
  • the brackets 14 or 14 ⁇ described in detail above are mounted with their winch gears 23 in the same configuration on the four connecting bars 12 assigned to the corners of the large container 10.
  • Two opposite winch gears 23 are each preferably connected by a shaft, so that only two hand cranks 24 need to be rotated synchronously to raise or lower the large container 10.
  • the outriggers 14 or 14 ⁇ move up or down along the support legs 21, as a result of which the large container 10 can be raised or lowered accordingly. But it is also possible to support a large container 10 in the raised state on the outriggers 14 or 14 'on the support legs 21.
