Definitions

  • the invention relates to a coupling device of a hoist for a container with a first coupling piece consisting of a socket with an upper flange-shaped edge and a second coupling piece designed as a pull rod with an upper flange-shaped edge, which is guided in the socket and is connected to drainage flaps via tension elements.
  • the coupling device engages with at least two hooks distributed over the circumference under the flange-shaped edges of the coupling pieces, the hooks of the coupling device being arranged in a housing with an upper towing eye each pivotable about an axis running through the hook, and the hooks for engagement under the flange-shaped edge of the first coupling piece are fixedly connected in the housing.
  • a coupling device of this type is already described in AU-A-8940/66.
  • the object of the present invention is to improve the functionality of a coupling device of this type.
  • Such a coupling piece can be designed to be particularly space-saving and compact if the pairs of hooks which engage under the two flanges of the coupling pieces are arranged offset with respect to one another in the direction of rotation.
  • the pull-out device of the coupling device can advantageously consist of a hydraulic piston-cylinder unit, the cylinder of which is fastened with a yoke carrying the pivotable hooks and the piston rod of which is fastened with its upper end to the upper end region of the housing, the piston-cylinder Unit is surrounded by a compression spring acting on the piston in the pull-out direction.
  • the hooks of the coupling device are pivoted in a similar manner. These are namely acted upon in the closing direction by compression springs which grip guide rods, and hydraulic piston-cylinder units are provided for pivoting the hooks in the opening direction. This also means that only one hydraulic line has to be provided for each piston-cylinder unit.
  • the piston-cylinder units are provided with freely extendable pistons for releasing the upper pair of hooks. With these, the upper hooks can be pivoted outwards against the spring force. So that the pull-out device is not pushed up by this handling is, at least on a pivot axis of a lower hook an upwardly projecting locking lever is pivotally mounted, on which the piston of the hydraulic piston-cylinder unit acting on the associated hook is articulated.
  • This piston is connected to the associated hook via an elongated hole pin guide in such a way that the at least one lever engages when the hook is opened via at least one projection of the yoke forming an abutment before the hooks are pivoted out completely.
  • the upper coupling piece is thus held in position by the lever when the lower and upper pair of hooks is pivoted out of the engagement position with the first and second coupling pieces of the container.
  • This mechanism thus enables the lower and upper hooks to be pivoted out of the engagement position with the first and second coupling pieces of the container without interference.
  • the lever In the pivoted-out position of the hooks, the lever remains in engagement with the projection of the yoke forming the abutment at the lower end of the pull-out device. This also ensures that when the coupling device is placed on the coupling mechanism of the container, a change in position of the pull-out device against the compression spring is prevented by the placement pulse. This means that the lower and upper hooks can be swiveled into their correct engagement position with the coupling pieces even when they are put on.
  • the coupling device consists in that the housing is divided into two, the lower part of the housing being rotatable via a rotary motor. Both housing parts are separated from each other by a rotating union.
  • the piston of the pull-out device is suspended in a cage that rotates with the lower Tell and in the protrudes upper housing part.
  • the cage is suspended in an oscillating manner in order to enable a corresponding pendulum movement of the hydraulic piston-cylinder unit of the pull-out device during the coupling process.
  • a container 10 placed on the floor is shown in an igloo shape.
  • the container 10 consists of a container-side closing mechanism 12 for emptying flaps 14 which are provided on the container.
  • the emptying flaps 14 are designed as bottom flaps that can be folded downward about a central hinge 15.
  • the container could also have any other shape and, for example, movable side flaps.
  • a first coupling piece 16 is screwed, welded or otherwise positively or materially connected from a bushing 22 with an upper flange-shaped edge 24.
  • the bushing 22 is aligned centrally. It also serves as a guide bushing for a second coupling piece 18 designed as a pull rod.
  • This second coupling piece 18 also has an upper flange-shaped edge 26. In the basic position, this upper flange-shaped edge 26 lies above the upper flange-shaped edge 24 of the first coupling piece 16.
  • the pull rod of the second Coupling piece 18 projects into the interior of the container 10.
  • tension elements 23 connected, which are connected to the freely pivotable ends of the emptying flaps 14. In the retracted state of the pull rod of the second coupling piece 18, the pull elements 23 are relaxed, as shown in FIG. 1.
  • the bushing 22 has a square bore and the pull rod of the second coupling piece 18 has a complementary profile. This ensures that the pull rod does not rotate about its own axis, as a result of which the free movement of the pull elements 23 could be impaired due to twisting or engaging with one another. In principle, however, other bore cross sections of the bushing 22 are also possible.
  • the coupling device 30 of a hoist 32 for handling the container 10 is also shown schematically.
  • the coupling device 30 is bolted to the lifting device via a towing eye 40.
  • the central element of the coupling device are a lower and an upper pair of hooks 34 and 36, respectively.
  • the lower pair of hooks serves to engage the first coupling piece 16.
  • the upper pair of hooks 36 can engage the second coupling piece 18.
  • the flange-shaped edges 24 and 26 of the coupling pieces 16 and 18 are ring-shaped and on their underside there is an annular groove 28 and 29 with an obliquely sloping flank.
  • the hooks 34 and 36 of the coupling device 30 are additionally secured by engagement in these annular grooves 28 and 29, respectively, in that they are drawn into the annular groove in particular under the load of the container.
  • the lower hooks 34 of the coupling device represent the load hooks, ie by means of these hooks the entire container is lifted up via the coupling piece 16 which is firmly connected to the container 10.
  • the Tension elements 23 the emptying flaps 14 are secured against opening when the container 10 is lifted from the floor.
  • the second coupling piece 18 is pulled up by means of the hooks 36 until the tension elements 23 are tensioned, so that this prevents the emptying flaps 14 from opening when the container 10 is lifted off the floor.
  • the inner square pull rod of the second coupling piece is pulled out by approx. 50 cm.
  • the container is raised, for example, by means of a boom 32 of a crane, not shown, and pivoted over the loading area to be filled, for example of a truck.
  • the pull rod and thus the pull elements 23 the emptying flaps 14 are opened, so that the collected content, for example waste, falls out of the container.
  • the container is closed again in the same way as described above and placed on the floor.
  • the hooks 36 which serve to move the pull rod of the second coupling piece 18 up and down, are moved by means of a pull-out device 46 which can be raised and lowered in the housing, as can be seen from FIG.
  • This pull-out device 46 consists of a hydraulic piston-cylinder unit, the cylinder of which is fastened to the upper end region of the housing 38 with a yoke 48 carrying the pivotable hooks 36 and the piston rod 50 of which is fastened with its upper end.
  • the piston-cylinder unit is surrounded by a compression spring which acts on the yoke 48 in such a way that the cylinder is pushed downwards with the hooks 36.
  • hydraulic fluid is displaced from the cylinder through a bore in the piston rod 50 (not shown).
  • the lower hooks 34 are arranged in the housing 38 of the coupling device 30 in a stationary manner and pivotably mounted about an axis 42, as shown in FIG.
  • the lower hooks 34 are removed from their closed position, i.e. their engagement with the first clutch device 16 is pivoted in the opening direction by hydraulic piston-cylinder units 62. They are moved against the spring force by compression springs 54 enclosed in guide rods 58.
  • the compression springs 54 which act on the hook 34 in the closing direction, serve to pivot the hooks 34 back for engagement under the flange-shaped edge 24 of the first coupling piece 16.
  • the hydraulic fluid in the piston-cylinder units is displaced.
  • Guide rods 60 are also articulated on the upper hooks 36 and are surrounded by compression springs 56.
  • All piston-cylinder units acting on the hooks 34 and 36 62 and 64 are supplied via a hydraulic feed line.
  • the pistons of the piston-cylinder units 62 and 64 can thus only be extended at the same time.
  • the locking levers 68 are pivoted into an open position, so that the yoke 48 together with the hooks 36 can be pushed up via the pull-out device 46. In this position, the locking lever is shown in Fig. 3 in a solid line.
  • the levers 68 must each engage over projections 74 of the yoke 48 which form abutments.
  • the locking levers 68 are pivoted via the piston rods 70 of the piston-cylinder units 62 to which they are articulated.
  • the lower hooks 34 with the pistons 70 of the piston-cylinder units 62 are via elongated holes 72 on the hook side, in which cylinder-side bolts 71 engage connected.
  • the locking mechanism thus functions as follows: When the piston 70 is extended, the locking lever 68 is pushed from its swung-out release position into the locking position. The lower hook 34 can remain in their locked position due to the elongated hole 72 during the first stroke part of the piston 70. Only when the piston on the piston side abuts the end of the elongated hole 72 is the corresponding lower hook 34 pivoted out of its engaged position. The previously described interaction of the hooks 34, 36 and the locking lever 68 ensures correct unlocking of the coupling device.
  • a coupling device enables a rotation of the lower part 84 of the housing 38 together with the hook pairs 34 and 36 arranged in the lower part and an attached waste container 10. This is particularly necessary if it is not a rotationally symmetrical container, for example a rectangular container , acts.
  • the upper part 80 of the housing 38 is connected to the lower housing part 84 via a rotating union 82.
  • the lower housing 84 is rotated via a hydraulically drivable rotary motor 88.
  • a pinion 90 flanged to this meshes with a gear 92 which is connected to the lower part 84 of the housing 38.
  • the piston 50 of the pull-out device 46 is suspended in a cage 86.
  • the cage 86 is suspended in the lower housing part 84 so that it rotates with it. However, it projects into the upper housing part 80.
  • the hydraulic rotary motor can be provided in the usual way for left and right rotation and can therefore be connected to two hydraulic lines.
