Definitions

  • the invention relates to a rail profile for crane monorail systems and slewing cranes with integrable energy chain.
  • a rail profile is often formed as a hollow chamber profile and has a plurality of functional elements, such as a track rail for a crane truck.
  • the crane monorail systems short crane tracks
  • swiveling crane carriers swivel cranes
  • Crane tracks occur in the field of handling technology in suspended systems, as ceiling systems, the so-called overhead crane tracks or crane monorail systems and as swiveling crane girders, which are arranged suspended on vertical columns (so-called vertical column swivel cranes) on.
  • the crane rail profiles or Krahnfahrbahnen can be designed as single lanes with a carrier or as multiple lanes with two or more mutually parallel crane lanes.
  • a crane running gear runs as a carriage or crane carriage with, for example, two, four, six or more rollers.
  • Hoists such as chain hoists or manipulators, which can be moved with the crane trolley to the crane rail profile are attached to the crane carriages.
  • the crane jumper there are one or more crane carriages, to which in the case of multiple lanes usually the chain hoists or manipulators are appended.
  • production goods can thus be displaced both in a longitudinal direction, also in the X direction, and in a transverse direction oriented orthogonally to the longitudinal direction, which is referred to as the Y direction.
  • the longitudinal direction is often referred to by the experts in the field of handling technology as X-crane track and the crane drive bridge as Y-crane track.
  • Chain hoists (cranes) and manipulators in most cases require energy that must be supplied to the individual chain hoists and manipulators in supply lines of the crane tracks or crane rail profiles.
  • the energy to be supplied can be supplied in the form of electrical energy ("electricity") or / and compressed air (“air"). In rare cases, in addition or alternatively, a supply of vacuum lines may be provided.
  • the individual cable drag carriages 40 in this case have brackets 41 for portions of the power lines 32a, which are preferably to be opened in order to be able to remove the respective sections of the power line 32a.
  • Examples of this type of power line 32a, 32b are in the Fig. 1 and Fig. 2 shown.
  • a power line 32a for compressed air is shown in FIG Fig. 2 an energy line 32b for electrical energy shown.
  • the power line 32a, 32b compressed air or pneumatic line 32a or electric line 32b
  • the power line 32a may be suspended in a spiral manner on the line drag rollers 40, as shown in FIG Fig. 1 is shown.
  • This type of suspension is particularly suitable for compressed air supply lines but also for vacuum lines or electrical supply lines.
  • a folded 32b (concertina-style) suspension is possible in Fig. 2 illustrated by an electric cable through a ribbon cable.
  • a power line 32 suspended with cable drag carriage 40 within the crane rail profile 10 reduces the travel range for the crane truck for chain hoists or manipulators because in one direction the tow tow carriages 40 with the power line attached thereto reduce the travel of the crane truck pushed together.
  • objects in the loops 32a or folds 32b of the power line 32 may catch, cause damage, and disable the cranes or manipulators.
  • Fig. 3 shows a crane rail profile 10 with a crane trolley 20, the power supply line 32 is formed on an additional C-rail 50a with a pull rope 51 as a spiral tube 32c.
  • the traction cable 51 is usually a wire rope spanned between the two ends of the C-rail 50a to movably hold the spiral hose 32c along the C-rail 50a.
  • the spiral 32c of the power line 32 is more or less pulled apart, analogous to a telephone cord of a conventional telephone set.
  • the energy line 32 as a spiral tube 32c and C-rail 50a can also be adapted for the supply of electrical energy.
  • the C-rail 50a is secured by brackets in the form of connecting webs 53 on the crane rail profile 10 or directly to a ceiling support.
  • the power line through a suspended on a C-rail 50a spiral tube 32c is extremely expensive and therefore expensive to purchase and installation. In addition, additional space in the vicinity of the crane rail profiles 10 is required and there are additional interference edges. In addition, due to the dead weight of the lateral C-rail 50, 50a, 50b and the spiral power line construction 32c arranged thereon, a non-negligible moment also arises on the crane rail profile 10 itself, for which reason counterweights have to be mounted or other no less expensive measures have to be carried out. In addition, there is a risk that transport goods or other objects caught in the spiral. Basically, the helical power line 32c is a functional malfunctioning solution because the tension of the helix exerts tensile forces and retracts a smooth-running crane truck.
  • FIG Fig. 4 Another technique of suspending a power line 32 for crane carriages 20 with support of a C-rail 50b is in FIG Fig. 4 shown.
  • the power line 34 which is shown here as a compressed air line, loop-shaped 32 d of carriage 52 (hose car), which are movable in the C-rail 50 b attached.
  • the crane trolley 20 can thus be moved completely in its crane rail profile 10 without the carriage of the power line 34 restricting its travel.
  • An advantage of the leadership of the power line 34 on a C-rail 50b with carriage 52 relative to the in Fig. 3 shown helical suspension is that power line 34 can be guided with larger diameters and higher weights to the crane carriages 20.
  • the energy supply 32 is guided here in a so-called energy chain 30, wherein the energy chain 30 is in turn supported in a guide channel 60 arranged externally laterally on the crane carrier rail profile 10.
  • the guide trough 60 is also referred to in the technical field as trough 60, U-trough 60 or U-profile 60 (U-rail profile 60).
  • compressed air lines and lines for electrical energy can also be performed together.
  • the energy chain 30 has a stationary 33 and a mobile end 34. While the power line 32 are fixedly connected to the supply lines at the stationary end, the mobile end is guided on a holding element 24 to the crane carriage 20.
  • the mobile end 34 of the energy chain 30 runs along accordingly and the energy chain 30 is received or deposited within the guide channel 60 more or less depending on the running direction of the crane carriage 20.
  • the stationary end 33 of the power line 32 remains stationary with the crane rail profile 10 is connected.
  • the disadvantages of an energy chain 30 guided in a guide channel 60 or U-profile 60 largely correspond to the abovementioned disadvantages for a spiral 32c power line guide 32 on a C-rail 50a or the guidance of the power line guide with carriage 52 in a C-rail 50b.
  • the individual power lines 32 are protected by the energy chain 30 itself.
  • the aforementioned rail profiles of FIGS. 1 to 5 in a known genus are hollow chamber profiles with internal road surface and offer the advantage that the treads of the road are largely protected against contamination and thus the smooth running of the crane car is not hindered by pollution or deteriorated.
  • the running surfaces are provided in the width and the lateral guides with a few millimeters of play, so that the running behavior of the crane car is not blocked and hindered.
  • the asymmetric rail profile shape does not take on equal tensile and compressive stabilities, such as a double T-beam profile. Therefore, this rail profile form has disadvantages in terms of rigidity and load capacity.
  • the energy supply lines are arranged laterally or parallel to the rail profile roadway, flanged either directly by means of additional holders and carrier systems on the rail profile or separately mounted with additional systems.
  • EP 1 506 934 A2 discloses a suspension crane track which comprises at least one crane track rail and a carriage guided on the crane track rail.
  • the crane track rail consists of several sections of a hollow profile.
  • An energy supply is provided entirely within the hollow profile and provides the drive of the carriage with energy.
