Definitions

• the invention relates to a device for picking up and lifting a container parked on the ground by means of a trailer vehicle, which comprises: a horizontal, U-shaped frame for gripping the container on its two longitudinal and one transverse side and a drawbar at the bottom the U-shaped frame is attached and can be coupled at its free end to a shunting vehicle.
• the invention has for its object to design a device of the type mentioned so that containers can be picked up, raised and lowered.
• the device as a whole should be able to be transported in a conventional container in a closed state.
• a device should also be designed so that loaded containers can be transported on public roads without excessive width.
• the U-shaped frame consists of telescopic elements. In the retracted state, the frame can therefore be made so that it fits into the interior of a container. However, when extended, the frame is large enough to hold this container. The container can be lifted and transported on the frame without exceeding the permitted vehicle width.
• the lifting devices of the device according to the invention are also designed to be telescopic. In the retracted state they have such a low height that they can be placed in the interior of a commercially available container. In the extended state, however, you can bring the container itself to a height so that its lower surface can be raised up to 1.5 m above the ground.
• the lifting devices are piston-cylinder arrangements so that a cylinder can be extended downwards in the vertical direction.
• a cable or the like is fastened to the extended end of the piston-cylinder arrangement, which is deflected via a roller arranged at the top and is fastened to the lower end of the container to be lifted.
• the free end of the cable pull is moved upwards and in this way takes the container with it.
• Fig. 1 shows a plan view of a device according to the invention.
• FIG. 2 shows a side view of the arrangement shown in FIG. 1.
• FIG. 3 shows a front view of two operating positions of the arrangement shown in FIG. 1.
• Fig. 4 shows one of the lifting devices in the retracted state.
• Fig. 5 shows one of the lifting devices in the extended state.
• Fig. 6 shows a top view of another embodiment of a device according to the invention.
• Fig. 7 shows a side view of another device according to the invention.
• FIG. 8 shows a side view of a further device according to the invention.
• 10 generally designates a transport vehicle which is designed via a drawbar device 14 and wheels which are not provided with reference numbers.
• the lifting vehicle 10 has a horizontally arranged U-shaped frame which consists of two longitudinal parts 12 and two transverse parts 11. Both the longitudinal frame parts 12 and the transverse frame parts 11 can be made telescopic. They are shown in the extended state in FIG. 1, so that the frame parts 11 and 12 enclose a container 15 from three sides.
• the associated means for moving in and out are not shown, nor are the associated units provided with reference numerals.
• Figure 1 it can be seen that there is another device according to the invention in the interior of the container 15. To distinguish, however, their parts are provided with the same reference numbers - but supplemented by the number 100. It can be seen that all frame parts 112, 111 and 120 are there in the retracted state.
• lifting devices 20 there are a total of four lifting devices 20 on the longitudinal frame parts 12. These are any devices which are able to raise a container attached to them by extending them and set them down by retracting them.
• FIG. 5 shows an embodiment of such a lifting device 20 with details and corresponding reference numerals.
• the lifting device 20 essentially consists of a vertically arranged tube 40 which is fastened to the longitudinal frame part 12. Inside the tube 40 there is a piston cylinder arrangement 41 and on the extendable piston rod, a cylindrical part 42 is attached. At the lower end of the cylinder 42, a wheel 43 can be attached, which can rest on the floor and allow corresponding compensatory movements there, so that the accommodation of a container is facilitated.
• the wheel 43 is arranged on a block 30, that is, the wheel 43 rests above the ground, so that a greater lifting height can be achieved, which is also clear from Figure 3 (right).
• a cable pull is fastened to the extendable part of the piston-cylinder arrangement 41, which is deflected via a roller fastened to the housing 40 at the top and guided downwards.
• the cable 44 can be attached to the corresponding fastening parts of a container when it is resting on the floor. This is the operating position shown in Figure 4. If the cylinder 42 is now extended, the wheel 43 comes to the ground or the block 30. You can no longer move downwards. However, if the piston of the piston-cylinder arrangement is extended further, the upper wheel 45 continues to increase in height and the rope 44 is pulled in in a ratio of 1: 2 and the container 15 is raised accordingly.
• the corresponding relationships can also be seen in FIG. 3, the state on the left being shown where the container 15 rests on the floor. In the position shown on the right, the lifting device 20 is fully extended so that a free space of 1.5 m below the container 15 has been created.
• Fig. 6 shows another embodiment of a device according to the invention, wherein the lower part shows the operating state where the frame parts 11, 12 one Grounded container 15 comprise, whereas the upper part of FIG. 6 shows the operating position where the container 15 rests on the frame parts 12 during transport.
• the frame parts 12 can be extended so far from one another that they enclose a container 15 resting on the ground at a sufficient distance.
• the maneuvering process by which the vehicle 10 is brought into the position shown in FIG. 6 below via the drawbar 14 or a semi-trailer with a corresponding vehicle is supported by the steerable wheels shown on the right in FIG. 6.
• the container 15 When the position shown in FIG. 6 is reached, the container 15 is raised with the lifting devices 20 already described so far that the lower edge or lower surface of the container 15 is arranged above the contact surface of the frame 12. The lifting process is ended in this position. Now the two frame parts 12 are moved towards one another, which is accomplished via the hydraulic device shown at 11, the steerable wheels shown on the right here taking a rolling direction which is essentially transverse to the longitudinal extent of the frame and the container.
• Fig. 7 shows a state just before the lowering of the raised container 15 is started.
• crossbars 40 which can be pivoted about vertical axes are shown. These are fastened to the longitudinal frame parts 12 and can be pivoted into the image plane in the state shown in FIG. 7. If the container 15 is then lowered, this creates an improved support for the container 15, as a result of which better options for fastening the container to the vehicle 10 are also achieved.
• FIG. 7 also shows that the transverse frame parts 12 and upper yoke parts can be extended in the longitudinal direction, so that instead of the container 15 shown in FIG. 7, a longer container could also be transported.
• FIG. 8 shows the embodiment in which a container 15 rests on the frame parts 12 and the vehicle 10 is connected to the saddle of a saddle vehicle by means of a saddle plate 14 with kingpins. 8 that can be realized in a device according to the invention. It is conceivable that the underground of the storage space for the container 15 is so uneven that the tractor executes a transverse pivoting to the longitudinal axis or to the actual direction of travel. With normal equipment, this could result in the kingpin being overused and breaking. Therefore, in a device according to the invention, the saddle plate can be moved about the longitudinal axis, so that the kingpin can pivot about the longitudinal axis and, regardless of the design of the saddle machine, even irregularly shaped floor irregularities do not lead to the destruction of the device.
• the two rear wheels could be retracted so far that they do not touch the ground, and in this connection the rear part of the load rests only on the two axles shown there.
• the two wheels are held rotatable about vertical axes, they can serve as a maneuvering aid when extended. This condition can be achieved with the wheels of the fixed axles touching the ground, but also without these in the maneuvering condition. Allowing turning angles of 180 ° and more for the two rear wheels makes maneuvering easier.
