Description of drawings
Content of the present invention is shown and is described below by means of the embodiment in accompanying drawing.In the accompanying drawings:
Fig. 1 illustrates the schematic diagram of schematic large hydraulic excavator;
Fig. 2 illustrates the schematic diagram according to the driving power train of the large hydraulic excavator of Fig. 1.
Embodiment
Fig. 1 illustrates the schematic diagram of the large hydraulic excavator 1 of schematic service weight＞100t, and this hydraulic excavator for example uses in the mine in order to obtain oil shale fuel.Relevant parts only are shown in figure, for example can be rotated to support on superstructure 2 and pilothouse 4 on crawler belt traveling mechanism 3.Schematically illustrated driving power train 5(6 equally only) one in, this driving power train comprises diesel oil motor 7, clutch coupling 8, pump dispenser gear train 9 and the hydraulic pump 10,11 that connects of flange mechanically on the pump dispenser gear train in this example.The zone that is arranged in pilothouse 4 is shown in addition and comprises the assessment unit 15 of optical indicating device.
Other driver part such as oil motor, rotary drive mechanism or like only are schematically shown, but are included in protection domain.
The drive area of the schematically illustrated large hydraulic excavator 1 according to Fig. 1 of Fig. 2.Schematically illustrated driving power train 5, comprise diesel oil motor 7, clutch coupling 8, pump dispenser gear train 9 and hydraulic pump 10,11 in this example.These driver parts 7,8,9,10,11 mechanical/hydraulic ground effect each other connect, and therefore are considered as a unit.Only single vibration receiver 12 to be installed regularly on pump dispenser gear train 9 in this example.The measuring-signal of vibration receiver 12 is transported to the assessment unit 15 of the pilothouse 4 that is arranged in large hydraulic excavator 1 by circuit 13.
In assessment unit 15, each driver part 7,8,9,10,11 that connects for the effect each other that drives power train 5 has special-purpose abnormal model
14, can identify by these models that are defined and amplitude thereof thus may defective parts.This model is coupled on the electronic evaluation system 16 that only schematically shows, this electronic evaluation system again with the BCS(vehicle control syetem of large hydraulic excavator 1) be connected, and indicate about one or more driver parts 7 to the operator by optical indicating device 17 in the needs situation, 8,9,10,11 the running status that departs from normal condition.
Selectively or concurrently also measurement data is continued to pass to outside Surveillance center by radio, can carry out there thus the comparison between measured value and ultimate value.Can start essential maintenance measures in case of necessity here.
Vibration receiver 12 side by side receives set/collect/total measuring-signal enduringly, each driver part 7,8,9,10 preferably, 11 vibration frequency.This resultant signal is transported to indicating device 17 by circuit 13 '.Carry out constantly each driver part 7,8,9,10 in assessment unit 15,11 incoming frequency from be deposited with this assessment unit in different abnormal model (ultimate value) between comparison.The in esse frequency of each driver part 7,8,9,10,11 and the critically limit of storage value 18,18 ', 18 " between deviation according to the corresponding rotating speed of engine 7 at abnormity notifying/in reporting middle generation and being stored in the fault reservoir of vehicle control syetem.Thus for each engine speed definition subordinate that is used for each driver part 7,8,9,10,11 that acts on each other connection/special-purpose ultimate value 18,18 ', 18 ".Therefore unlike the prior art, always provide the ultimate value 18,18 ', 18 of variation for each driver part 7,8,9,10,11 ", the ultimate value of these variations processes in data/preparation/bring high degree of flexibility when prefabricated.The abnormity notifying mechanical data (for example pressure of engine speed, temperature, pump 10,11) relevant with other passes through other sensor 19,20 and subordinate/ relevant circuit 21,22,23,24 and is transported to the indicating device 17 of vehicle control syetem.
Each driver part 7 for storage in assessment unit 15,8,9,10, each signal of 11 produces special-purpose abnormal model, thus by these determine abnormal and relatively can identify possible defective driver part with the signal that is provided by vibration receiver 12.
