Definitions

  • the present invention relates to an attachment for a construction machine, which is particularly intended and suitable for picking up and transporting drums and comparable objects and loads.
  • drums which carry rolled up hoses, cables or the like and which are provided with two opposing recesses in the area of their central axis for this purpose, as well as other objects provided with such opposing recesses, by inserting a massive rod inserted from one side into one of the recesses and then lifted together with the drum. It is also known to use forklifts to lift such drums onto their load-handling devices.
  • the attachment according to the invention for a construction machine comprises two opposite one another at a distance, im Side wall elements of essentially the same design, each of the wall elements being assigned a pin element, at least one telescopic strut element connecting and supporting the two side wall elements, an interface element which is connected on the one hand to the at least one strut element and on the other hand an interface for attaching the attachment of the machine, and at least one variable-length cylinder element which is set up and arranged to adapt the distance between the two wall elements.
  • the attachment according to the invention By engaging the respective recesses of the object to be transported from both sides with the attachment according to the invention and in particular with the two opposing pin elements, a completely symmetrical distribution of forces can be achieved, which also only acts along the extensions of the two wall elements in the vertical direction. It goes without saying that the attachment according to the invention can be used with any construction machinery, for example any industrial trucks or excavators.
  • the at least one strut element can have a rectangular and, in particular, also a square cross section. Alternatively, however, other shapes could of course also be selected, for example a round or oval-shaped cross section of the at least one strut element.
  • At least two telescopic strut elements can be provided, which extend parallel to one another and are preferably spaced approximately the same distance from the two pin elements. In this way, a triangle or polygon is formed between the at least two strut elements and the pin elements, what the absorption of moments in the invention Improve attachment and prevent or at least suppress twisting in it.
  • the two wall elements can be formed tapering in the direction of the at least one strut element towards the respective pin element. In this way, on the one hand, sufficient installation space is created in the area of the strut element or elements to connect it to the respective wall elements, while on the other hand, less installation space is required in the area of the respective pin element and weight and material can be saved accordingly due to the tapering shape of the wall elements.
  • the at least one variable-length cylinder element can be arranged in the immediate vicinity of the at least one strut element in the direction of the pin element in one embodiment.
  • the length-adjustable cylinder element lies directly below or directly above the at least one strut element.
  • the at least one length-adjustable cylinder element can also be integrated with the at least one strut element, wherein a corresponding plurality of length-adjustable cylinder elements can be provided, in particular with a plurality of strut elements.
  • the length-adjustable cylinder elements can accordingly be integrated or received within the corresponding strut elements.
  • the at least one variable-length cylinder element can be operated hydraulically or electromechanically.
  • hydraulic cylinders which are known per se or which can be changed in length can be used electromechanical units, such as linear motors or electrically operated rack and pinion arrangements.
  • the attachment according to the invention can furthermore comprise a connection element which can be connected to a corresponding circuit of the construction machine in order to supply the variable-length cylinder element.
  • a connection to a hydraulic circuit of the construction machine as well as to an electrical on-board network circuit can be considered, depending on the design of the corresponding length-adjustable cylinder element.
  • the attachment according to the invention can comprise a rotary motor which is assigned to the interface element and is set up to cause the at least one strut element and thus also the side wall elements connected to it to rotate relative to the construction machine, in particular over a full 360 ° and / or in both directions of rotation, and / or comprise at least one rotary motor which is assigned to one of the two wall elements and is set up to cause the corresponding pin element to rotate, in particular in both directions of rotation.
  • the recorded object can be swiveled or rotated about one or two of its main axes, which can be used advantageously in particular in the case of drums with cables or hoses carried on them for rolling up and unrolling them.
  • the respective motor is preferably made strong enough to be able to cause a rotation of the recorded object in any spatial orientation, even with its maximum permissible weight. This is particularly significant if the object has already been pivoted by a component of the construction machine into an orientation in which the load thereof makes it difficult to rotate with respect to an unswiveled orientation thereof.
  • the distance between the two wall elements can be adjusted in a range of a maximum of 250 cm and a minimum of 80 cm, which are typical size ranges of such rollers or drums, but, as mentioned, any other objects with opposing recesses of the attachment according to the invention are included.
  • an attachment according to the invention for a construction machine is shown in two operating states and is each designated with the reference numeral 10.
  • the state corresponds to Figure 1a a state of a maximum distance between the two opposing wall elements 12a and 12b, while the state is off Figure 1b corresponds to a state with a minimal distance between the two wall elements 12a and 12b.
  • the attachment 10 can be arranged, for example, with respect to a drum (not shown) to be accommodated in such a way that the two pin elements 14a and 14b assigned to the respective wall elements are placed in the area of the two lateral recesses of the drum and then the two wall elements 12a and 12b are moved towards one another so far, until the two pin elements 14a and 14b come into engagement with the two recesses of the drum.
  • a drum not shown
  • other objects can also be picked up with the attachment 10, for example rolls, baskets, etc.
  • two telescopic strut elements 16a and 16b are provided in the embodiment shown, which in turn are supported by a common interface element 18, which also provides an interface for attaching the attachment 10 to the construction machine not shown offers.
  • a common interface element 18 which also provides an interface for attaching the attachment 10 to the construction machine not shown offers.
  • the first telescopic strut element 16a shown below is only connected to the first wall element 12a shown on the left, while it is in the second wall element 12b in a sliding or free manner by a particularly in Figure 3 to be recognized opening 20a is passed.
  • the second telescopic strut element 16b is only firmly connected to the second lateral wall element 12b and passes through the first lateral wall element 12a in an opening not shown in the figures.
  • the attachment area of the second telescopic strut element 16b on the second lateral wall element 12b is also shown in FIG Figure 3 indicated and denoted by the reference numeral 20b.
  • Indicated length-adjustable cylinder element 22 is provided, which is arranged directly above the telescopic strut elements 16a and 16b and can be operated hydraulically or electromechanically, for example.
  • embodiments are also conceivable in which several length-adjustable cylinder elements are used together with two telescopic strut elements or a different number of cylinder elements and / or strut elements.
  • connection element can also be provided in the area of the interface element 18, with which lines assigned to the attachment can be coupled to a corresponding on-board network of the respective construction machine.
  • At least one rotary motor can be provided both in the area of the interface element 18 and in the area of at least one of the two wall elements 12a, 12b, which rotates the at least one strut element 16a, 16b relative to the construction machine or rotates the corresponding pin element 14a, 14b can cause relative to the respective wall element 12a, 12b.
  • a rotation of the picked-up object about a vertically extending axis and / or an axis extending horizontally through the two pin elements 14a and 14b can be achieved, while all further rotations and translations of the picked-up object in space can be performed by appropriate actuation of the construction machine .
  • the attachment 10 can be present in essentially any scaling
  • the distance between the two can, in particular, correspond to commonly used drums or rollers Wall elements in the in the Figures 1a and 1b
