Definitions

  • the invention relates to a lifting device for portable containers, e.g. Containers, shelters, swap bodies or the like, with several rack winches to be fastened to the container, the winch housing of which can be connected to the container, can be raised and lowered along a supporting leg with a rack, and have parts which can be pivoted away or removed.
  • portable containers e.g. Containers, shelters, swap bodies or the like
  • rack winches to be fastened to the container
  • the winch housing of which can be connected to the container can be raised and lowered along a supporting leg with a rack, and have parts which can be pivoted away or removed.
  • a lifting or lowering device for transportable containers has already become known from German patent specification 2 540 400, in which the arms can be separated from the rack winches or their winch housings.
  • the rack and pinion winch gear is in one piece connected with relatively high winch housings and forms a component with a correspondingly high weight.
  • Another disadvantage of this known device is that, due to the closed winch housing, the idle stroke must always be bridged both upwards and downwards via the rack and pinion gear by time-consuming crank work.
  • the invention has for its object to provide a lifting or depositing device for transportable containers, in which by moving the support legs in the winch housing by hand the time-consuming idle stroke to be carried out via the winch gear can be avoided and at the same time with the individual parts of the lifting or A further weight saving is achieved so that its handling is facilitated. Furthermore, if necessary, cleaning of the gears or at least the drive pinion of the rack winches and the racks in the winch area should be made possible.
  • each winch housing is designed as an attachment or add-on gear.
  • the invention further makes it possible that the top bridging of the idle stroke by actuating the winch gears is omitted in the case of pivoted attachment or add-on gear units, by merely moving the support legs with their toothed racks in their winch housings by hand downwards or upwards. When dismantling the lifting or lowering device, it is also possible to pull the support legs with their racks out of the winch housing completely.
  • the embodiment of the invention according to claim 2 has the advantage that the support leg with rack in the guide part of the winch housing can be secured against unwanted slipping by the friction brake device when the attachment gear is pivoted out or removed.
  • the further embodiment of the invention according to claim 3 has the advantage in the case of winch housings which can be opened outwards, that even when the attachment or extension is pivoted out or removed gear rack (with the support leg) can be fixed to the guide part of the winch housing.
  • This advantage proves to be very useful if the lifting or depositing device is heavily soiled with a more or less highly supported container, so that there is a fear of stiffness or even blocking of the rack and pinion winches to be operated for a necessary manipulation of the container. In this case, all you have to do is swivel out or remove the attachment or add-on gearboxes, so that at least their drive pinions and the areas of the toothed racks can be easily cleaned relative to the gearboxes.
  • This work can be done with the lifting or lowering device under load, because when the gearbox is swung out or removed, the rack in question is fixed to the winch housing by the locking device.
  • the associated lifting device advantageously enables the transmission to be released or separated from the respective rack under load.
  • This embodiment of the invention also advantageously allows the attachment or add-on gearboxes to be removed and stored in a safe place when the container is supported on the lifting or depositing device, thereby securing against misuse of the lifting and depositing device, for example when the container is standing for a long time is guaranteed.
  • the embodiment of the invention according to claim 4 has the advantage that the establishment of a perfect operative connection between a respective attachment gear and a rack is facilitated.
  • the guide part which slides along the support leg, also forms a guide for the housing of the attachment gear to be fitted.
  • the guide part of the winch housing forms a part which is detachably connected to a boom to be attached to the container, the weights of the individual parts of the lifting or lowering device are further reduced and consequently their handling is made even easier.
  • the attachment gear is detachably connected at its upper and lower ends by plug bolts to the guide part of the winch housing, the gear can advantageously be pivoted up or down by the other plug bolts by pulling out only one plug bolt for the cleaning purposes mentioned at the beginning.
  • the attachment gear overlaps the guide part of the winch housing laterally with at least one gear, a relatively large reduction ratio can advantageously be achieved with a gear unit of relatively flat construction.
  • a simple expedient embodiment of the lifting and locking device can be seen from claim 9.
  • the wedge-shaped parts can move against or away from each other, for example, by means of a spindle which is axially fixed in the locking element but can be rotated by hand with right and left-hand threads at the ends, which engage in corresponding threads in the wedge-shaped parts.
  • the locking element can be kept relatively small in size, which means saving weight, the safety rod in the inserted state prevents the support leg from breaking out of the guide part of the winch housing (tilting around the locking element) to the outside.
  • FIGS. 1-13 and 14 to 18 represent lifting and depositing devices which are intended for containers with a generally rectangular outline. Accordingly, both exemplary embodiments have four support legs 11 with associated rack and pinion jacks 12 and 12 ', which are laterally attached to a container, e.g. 10 or at the corners can be releasably attached.
  • a container can be lifted and e.g. are placed on the loading surface of a truck or, conversely, lifted from this loading surface and carried by the devices in a raised state or also placed on the floor or other supporting surface.
  • a rack and pinion winch 12 with an associated support leg 11 of the first exemplary embodiment is described below. All rack winches 12 and support legs 11 correspond to each other.
  • the rack and pinion winch 12 has a guide part 14, which is guided on the support leg 11 and has a substantially U-shaped cross section.
  • the support leg 11 consists, for example, of a square tube.
  • the lower end of the support leg 11 carries a foot plate 15.
  • the guide part 14 is rigidly connected to the arm 13 in the exemplary embodiment, but a detachable connection of these parts is also possible.
  • the arm 13 can be detachably attached to the side wall of the container 10 in the corner region thereof.
  • a rack 16 is preferably attached centrally.
  • the rack and pinion winch 12 also contains an attachment or add-on gear 17 which is arranged on the guide part 14 so as to be pivotable or removable.
  • the housing of the auxiliary transmission 17 is encapsulated, and it extends partially in the attached state in the guide part 14 with a U-shaped cross section, as can be seen from FIGS. 3 to 5.
  • the auxiliary gear 17 is detachably connected to the guide part 14 by similar plug pins 18, which extend appropriately through corresponding bores 20, 21 in the guide part 14 and 22 in the housing of the auxiliary gear 17.
  • the plug pins 18 carry at one end a part 23 with an inwardly directed screw surface which cooperates with an outwardly pointing screw surface on parts 24 which are fastened to the outside of the guide part 14.
  • the parts 24 contain central bores through which the socket pins 18 extend.
  • the opposite ends of the plug pins 18 are equipped with grooves 25 for receiving securing tabs 26 provided with corresponding slots.
  • a corresponding rotation of the plug pins 18 by means of the levers 27 due to the interaction of the screw surfaces on the parts 23 and 24 can result in the housing of the auxiliary gear 17 being braced in the guide part 14.
  • the socket pins 18 also secure the guide part 14 against "spreading" through the support leg 11 when this tipping forces act on what can occur in uneven terrain.
  • An additional or alternative safeguard in this regard is formed in the exemplary embodiment by two retaining tabs 28 (FIGS. 1 and 4) fastened to the housing of the auxiliary gear 17 at the same height, which laterally overlap the guide part 14 when the auxiliary gear 17 is attached.
  • the hand crank of the auxiliary gear 17 is designated and at 30, 31 and 32 some gears of the auxiliary gear are indicated in Fig. 1.
  • the gear wheel 32 with the largest diameter is arranged in a housing part 34 which overlaps the guide part 14 laterally.
  • the gear wheel 32 is non-rotatably seated on a shaft 33 (FIG. 5) on which the drive pinion 35 for the toothed rack 16 is also fastened to the support leg 11.
  • the drive pinions 35 and the toothed racks 16 can become dirty, which can cause the rack winches 12 to become stiff or even blocked.
  • the drive pinions 35 and the racks 16 also compared to the front gear 17, the front gear 17 are either removed from the guide members 14 or swung out, for example, according to FIG. 7.
  • the securing tabs 26 are first removed so that the plug pins 18 can be pulled out to the right as shown in FIG. 2. Then the attachment gear 17 can be separated from the guide part 14.
  • the guide part 14 of the winch housing with a U-shaped cross section is provided with laterally aligned openings 36 and 37 on its two legs near the front. The latter are open at the bottom.
  • One or both socket bolts are inserted laterally into the openings 37 before pulling out.
  • 18 a locking element 38 inserted, which is provided with a toothing 39 (Fig. 10), which in this Engagement with the rack 16 is brought.
  • the locking element 38 is positioned in this way in the openings 37, wedge-shaped parts 41 are driven from the outside into the remaining spaces 40 between the upper edge of the locking element 38 and the openings 37, which bring about a slight lifting of the guide part 14 relative to the support leg 11 , whereby the friction between the drive pinion 35 and the (loaded) toothed rack 16 is reduced to such an extent that the auxiliary gear 17 can be removed or swung out of the guide part 14 after removal of one or both socket bolts 18.
  • a safety rod 42 is inserted through the openings 36, which prevents the support leg 11 from tipping out of the guide part 14 to the front when the auxiliary gear 17 is removed.
  • the securing rod 42 is in contact with the toothed rack 16.
  • the toothed rack winches 12 consist of a known embodiment which is self-locking under load.
