Definitions

  • the present invention relates to a crane with a drive device, wherein the crane has an undercarriage and a superstructure.
  • the crane superstructure is rotatably mounted about a vertical axis of rotation about the undercarriage.
  • a rotary union which represents a connection between the uppercarriage and lowercarriage. This connection may be, for example, hydraulic or electrical type.
  • An internal combustion engine has its highest power at its maximum speed and can be operated in this area.
  • the torque and / or power transmission means at least one propeller shaft (16), a first angular gear (13), at least one further in the superstructure (3). arranged angular gear (13) with a performance continuity to a pump distributor gearbox (14), and that the undercarriage motor (10) is an internal combustion engine.
  • the torque and / or power transmission means is a mechanical torque and / or power transmission means and is used in particular for the mechanical transmission of forces, torque and power from the undercarriage engine to the arranged in the uppercar Crane actuators, which are driven by the superstructure drive or are driven.
  • the at least one propeller shaft of the torque and / or force transmission means is a king shaft, and / or comprises.
  • the torque and / or power transmission means has at least one coupling by means of which the superstructure drive is disengageable and engageable, wherein the clutch is preferably arranged in the undercarriage or in the region of the undercarriage.
  • the torque and / or power transmission means can be driven directly by a power take-off of the undercarriage engine and / or that the torque and / or power transmission means can be driven by a power take-off of a manual or automatic transmission and / or that the torque - And / or power transmission means is driven by a power take-off of a transfer case.
  • the superstructure drive comprises at least one pump distributor gearbox.
  • the undercarriage engine is a powerful and large-sized internal combustion engine, in particular a diesel engine, wherein the power of the undercarriage motor is preferably dimensioned such that required by the undercarriage engine power required for crane operation at low engine speed, especially in a speed range above Idling speed up to about twice the idle speed, can be provided.
  • an auxiliary motor is provided on the superstructure or in the region of the superstructure, by means of which the superstructure drive can be driven.
  • the present invention relates to a crane with the features of claim 10. Thereafter, it is provided that a crane is provided with at least one drive device according to one of claims 1 to 9, wherein the crane is preferably a mobile crane, in particular a large mobile crane.
  • FIG. 1 shows a schematic side view of a crane 1 with a drive device according to the invention.
  • the crane 1 is a mobile crane. 1
  • FIG. 2 further shows a schematic view of the drive device according to the invention in a first embodiment.
  • an angle gear 13 which is preferably designed with 90 ° angle, used in the vehicle frame centered and the drive to the superstructure 3 forwarded.
  • another angle gear 13 is realized with performance continuation to a pump distributor gear 14.
  • a suitable position of the pump distributor 14 can also be achieved by means of a further angular gear 13, not shown. Namely, it should be noted that in the uppercarriage 3, the boom 7 and the luffing cylinder 8 occupy the area of the center of rotation and about the longitudinal axis. Thus, another bevel gear 13 may be necessary to get out of this area.
  • a further object of the invention is the fuel economy, it is very advantageous that the superstructure drive, regardless of where it is located, for example, via a clutch 18 is switched off. Further, a clutch 50 is provided in the undercarriage, which actively decouples the undercarriage drive and close to the branch for the superstructure drive and thus reduces the friction losses.
  • the translation of the superstructure drive can be freely selected as needed.
  • the gear ratio can be determined depending on the gear as needed. Preferably, however, an optimum ratio to the diesel engine 10 is set. This ratio can either be equal to the engine speed, or increased to fast.
  • the large-sized undercarriage engine 10 has sufficient power for crane operation. It is designed for driving performance. So far, the superstructure engine was rather smaller from the maximum power, as this weight and cost were saved. However, this saving was associated with the disadvantage of operating in the higher speed range, which caused a higher fuel consumption.
  • the undercarriage engine 10 can thus be operated in the superstructure operation preferably in a consumption-optimized range at a reduced speed.
  • the diesel engine 10 For crane operation, it is important to have the diesel engine 10 in the optimum fuel economy map operate. In a performance comparison of the required power to the power provided, the engine speed is correspondingly assigned to operate the engine in the optimum fuel economy map.
  • the pumps 17 for the auxiliary consumers in the undercarriage also via a coupling 19 selectively decoupled.
  • this clutch must also be selectively switchable, for example, to allow driving from the superstructure 3 out (eg, crab). According to the prior art, the pumps 17 were not switchable.
  • FIG. 3 Another aspect of fuel economy can be taken from the FIG. 3 taken with the consumption characteristics for a large and a small engine.
  • This diagram represented a simplified representation of the speed-dependent fuel consumption of an internal combustion engine.
  • the large diesel engine 10 can be operated at a low idle speed nL large .
  • the previous small diesel engine had to be operated at a higher idle speed nL small .
  • Next fuel savings from the low operating speed nB may be large in comparison to the higher - operating speed can be achieved nB small - explained previously.
  • each bevel gear 13 is about 0.99 to 0.98. Thus, sufficient power is still available at the pump distributor 14 in the uppercarriage 3.
  • Another positive aspect is the lower noise, since the diesel engine 10 is operated at a low speed. This aspect can also have an impact on fuel consumption. Since the diesel engine 10 is very large, it can be operated at low speed and generates accordingly little heat. Thus, the engine cooling fans 53 may be operated at low speed or even not at all.
  • an auxiliary motor 31 may be provided on the uppercarriage 3.
  • the auxiliary motor 31 may be made variable in size.
  • This auxiliary motor 31 may include a starter 33 and a generator 32.
  • the generator 32 could then take over the supply of electrical consumers, such as lighting, during the standby time.
  • this auxiliary engine 31 can also operate the flight warning light.
  • the air conditioning system 52 or a preheating of selected components could also be operated by the auxiliary engine 31.
  • an emergency operation could also take place via a propeller shaft 16 to the pump distributor 14.
  • this compound also has a separable coupling 51.
  • the auxiliary motor 31 could be used for charging purposes.
  • auxiliary motor 31 could also be a separate unit from the superstructure 3.
  • FIG. 2 Another embodiment not shown in the drawings preferably relates to large cranes, in which the distance between the engine and rotary feedthrough is very large.
  • the drive shafts 16 of the axes can be used.
  • the angle gear 13 (see. Fig. 2 ) are driven by an output shaft which is branched off at a final drive.
  • a clutch must be provided on each axis, so that the respective axle can be decoupled from the drive train, to prevent the wheels rotate during crane operation.
