Definitions

  • the present invention relates to a material handling device according to the
  • Conventional material handling devices are constructed from an undercarriage and an uppercarriage, the uppercarriage and undercarriage being connected to one another by means of a slewing ring, and the uppercarriage having the articulation point of the working device, the driver's cab and the energy unit with a counterweight.
  • the foot of the boom on the superstructure whereby other work equipment can also be attached.
  • it is desirable to provide the uppercarriage at a great height above the ground e.g. when goods have to be lifted over larger obstacles, such as the side walls of railway wagons or ships.
  • the crane operator cabin can be attached to the superstructure, for example, in a height-adjustable manner.
  • DE 31 24 303 AI shows a telescopic crane in which the position of the crane driver's cab can be varied.
  • Such telescopic cranes are frequently used on construction sites and are characterized by a special structural design and in particular by the fact that the counterweight is tensioned either with weight compensation in the jib and / or additionally on the jib on the superstructure.
  • the utility model DE 297 18 479 Ul discloses a crane vehicle which has an additional attached to a telescopic boom. Liche driver's cab to make areas that are not visible from the ground visually accessible to the crane operator. Since the additional driver's cab is not attached directly to the superstructure, but rather to the moving boom, it describes an arcuate movement path during work. An additional adjustment of the inclination of the crane cab is necessary to compensate for the curved movement of the boom. In addition, the additional driver's cab usually has to be dismantled when transporting the working machine.
  • the superstructure is arranged at a great height above the undercarriage by means of an intermediate structure.
  • a handling device has the disadvantage that the overall center of gravity of the machine is at a great height, which can lead to instability of the machine.
  • the energy unit is also at a great height, which, with a combustion or electric motor and hydraulic pumps, is the main cause of the noise, which leads to undesired sound propagation.
  • the machine operator's rear view is severely impaired by the superstructure.
  • the assembly, maintenance and repair of the machine are also unfavorable due to the high height.
  • An example of this known construction is disclosed in US 3,545,633, in which the undercarriage is provided with a column on which the energy unit and above it the slewing ring sit.
  • the device stand provided for this purpose can thus be arranged at a distance from the superstructure.
  • Another advantage of the invention is that the noise pollution can be kept low, since the energy unit is arranged on the superstructure and thus comes to be relatively close to the ground.
  • the development according to claim 4 has the advantage that the field of vision of the machine operator to the rear is improved in comparison to the prior art, since only the equipment stand and not the superstructure with its superstructures is in a raised position.
  • the material handling device can be used in a simple manner as a standard machine if the intermediate structure is omitted, since either the device frame or the intermediate structure can be mounted on the superstructure in the same way.
  • stepless height regulation is made possible. This is achieved in particular with little design effort and cost-effectively that a hydraulic pump is already available for the working device, which additionally supplies the height regulation of the pylon-like intermediate construction with or without a telescopic arrangement. Furthermore, there is a good distribution of the center of gravity over the entire height-adjustable range, so that a work assignment in any position is possible.
  • the material handling device can be implemented with a simple structure, the foot point of the work equipment and the driver's cab can be variably adjusted in height by means of the equipment stand, both to lift goods over larger obstacles and to make the work area of the work equipment more manageable.
  • the height adjustment of the device block can alternatively or additionally also be carried out by choosing an intermediate structure with a predetermined length.
  • Such an intermediate structure can be characterized by its stable and rigid construction, as well as the simple and particularly inexpensive assembly.
  • the development according to claim 9 has the advantage that, in particular, the superstructure remains in a stable position when the device is rotated about the slewing ring, the height of the equipment being regulated only slightly by the device bracket. Furthermore, all modules remaining on the superstructure serve as a counterweight, so that the overall stability of the handling device is guaranteed.
  • Fig. 1 is a schematic representation of an embodiment of a material handling device according to the present invention.
  • FIG. 1 shows an embodiment of a material handling device, which here is in the form of an excavator structure driven hydraulically via a cylinder.
  • the material handling device has an undercarriage 50, an uppercarriage 40 coupled to it via a slewing ring 45, an equipment stand 20 and a working device 10.
  • the superstructure 40 contains a base frame on which an energy unit 42, which is a diesel or electrical unit, a control unit, tanks, counterweights and hydraulic devices are arranged.
  • the equipment block 20 contains a driver's cab 22 and a pivot point for the work device 10.
  • a rigid, pylon-like intermediate structure 30 is arranged between the superstructure 40 and the equipment block 20, so that they are spaced apart from one another. This means that both the driver's cab 22 and the articulation point for the working device 10 are spaced apart from the superstructure 40 by the pylon-like intermediate structure 30 and, moreover, the height can be adjusted.
  • Both the articulation point of a boom 12 of the working device 10 and an articulation point of a first hydraulic cylinder 16, which controls the arcuate movement of the boom 12, are located on the device block 20.
  • the working device 10 also has a boom arm 18 which can be moved by means of a second hydraulic cylinder 19.
  • a gripping device is attached to the leg handle 18.
  • the pylon-like intermediate structure 30 is preferably designed as a hollow cylinder made of metal, which is screwed to the base frame of the superstructure 40 and the device block 20 on its circumference. If the pylon-like intermediate structure 30 is omitted in order to use the material handling device as a standard machine, the device block 20 is attached to the base frame of the superstructure 40 by the mounting devices used for the intermediate structure 30.
  • the hydraulic supply to the working device is preferably supplied via hydraulic lines from the energy unit 42, which run through the hollow cylinder of the pylon-like intermediate structure 30 or on the outside thereof.
  • pylon-like intermediate structures 30 of different lengths can be used, so that an adaptation of the material handling device to the given working conditions is easily possible.
  • the undercarriage 50 is designed as a crawler undercarriage, for example with a crawler track 52, the use of wheels for use on roads or rails or a stationary substructure also being possible.
  • the individual components of the material handling device are each provided in a modular manner and releasably connected to one another. This enables assembly and disassembly of the slewing ring 45, superstructure 40, intermediate structure 30 and device block 20.
  • different types of material handling equipment can be implemented. So can the one described above Construction with undercarriage - slewing ring - uppercarriage - trestle equipment or boom can be realized as well as a variant in which the trestle is arranged directly above the slewing ring.
  • the pylon-like intermediate structure 30 can be adjusted in steps or continuously in height by means of a telescope arrangement and / or by means of a hydraulic device. This makes it possible to transport loads at any height depending on the application.
  • the intermediate construction can also be made in one piece, e.g. by welding, be connected to the superstructure and / or the device block.
  • the intermediate construction can alternatively also be screwed or bolted to the uppercarriage and the equipment stand, i.e. be connected in a modularly releasable manner and have any shape in order to place the working device at a greater distance above the superstructure or above the floor. This increases the working range of the material handling device, and inexpensive standard components, in particular a conventional working device, can be used as individual components or assemblies.
  • the working device can also be arranged on the equipment stand, the driver's cabin being attached to the superstructure.
  • a material handling device is thus created, which is constructed from an undercarriage and an uppercarriage with a working device, a driver's cab and an energy unit, an equipment stand which supports the working device being attached to the uppercarriage in this way by an intermediate construction. can be brought that the working device is arranged at any distance from the floor on the material handling device.
