Definitions
- the present invention relates to a shovel including a turning motor driven by electric power stored in a storage battery.
- Patent Document 1 does not mention the case where a serious failure occurs in the storage system and it is necessary to stop the storage system.
- the storage system is stopped, even if the shovel can drive the electric swing system by the engine, the storage system can not absorb the regenerative electric power from the electric swing system, so the electric swing system can not be electrically braked. Therefore, the shovel needs to be maintained in a state in which the electric turning system is mechanically stopped.
- the shovel is in an unstable posture on a slope, it may be undesirable in terms of safety to stop the motor-driven turning system mechanically.
- the shovel includes an engine, a motor generator that functions as a generator that utilizes the driving force of the engine, and a motor generator that functions as a motor capable of assisting the engine, a storage system, for turning Excavator having a motor, a bus line connecting the motor generator, the storage system, and the turning motor, and a control device for controlling the movement of the motor generator, the storage system, and the turning motor And the control device supplies the generated electric power of the motor generator functioning as a generator to the turning motor when the turning motor is driven in a powering operation when the storage system is stopped.
- the regenerative electric power of the turning motor is supplied to the motor generator that functions as a motor when the turning motor is to be regenerated.
- the above-described means provides a shovel capable of appropriately driving the electric swing system even when the storage system is stopped.
- FIG. 2 is a block diagram showing a configuration of a storage system. It is a flowchart which shows the flow of electrical storage system stop processing. It is a flowchart which shows the flow of turning control switching processing. It is a flowchart which shows the flow of the turning regeneration process in turning control at the time of an electrical storage system stop.
- FIG. 1 is a side view showing a hybrid shovel to which the present invention is applied.
- An upper swing body 3 is mounted on a lower traveling body 1 of the hybrid shovel via a turning mechanism 2.
- a boom 4 is attached to the upper swing body 3.
- An arm 5 is attached to the tip of the boom 4, and a bucket 6 is attached to the tip of the arm 5.
- the boom 4, the arm 5 and the bucket 6 constitute an excavating attachment which is an example of an attachment, and are hydraulically driven by the boom cylinder 7, the arm cylinder 8 and the bucket cylinder 9 respectively.
- a cabin 10 is provided in the upper revolving superstructure 3 and a power source such as an engine is mounted.
- FIG. 2 is a block diagram showing a configuration of a drive system of a hybrid shovel according to an embodiment of the present invention.
- the mechanical power system is shown by a double line, the high pressure hydraulic line by a thick solid line, the pilot line by a broken line, and the electric drive and control system by a thin solid line.
- An engine 11 as a mechanical drive unit and a motor generator 12 as an assist drive unit are connected to two input shafts of a transmission 13 respectively.
- a main pump 14 as a variable displacement hydraulic pump and a pilot pump 15 as a fixed displacement hydraulic pump are connected to an output shaft of the transmission 13.
- a control valve 17 is connected to the main pump 14 via a high pressure hydraulic line 16.
- the control valve 17 is a control device that controls the hydraulic system in the hybrid shovel. Hydraulic actuators such as hydraulic motors 1A (for the right) and 1B (for the left) for the lower traveling vehicle 1, the boom cylinder 7, the arm cylinder 8, and the bucket cylinder 9 are connected to the control valve 17 via a high pressure hydraulic line. .
- the hydraulic system includes hydraulic motors 1A (for the right) and 1B (for the left) for the lower traveling vehicle 1, a boom cylinder 7, an arm cylinder 8, a bucket cylinder 9, a main pump 14, and a control valve 17.
- a storage system 120 including a capacitor as a storage battery is connected to the motor generator 12 via an inverter 18 as a motor generator control unit. Further, the storage system 120 is connected with a turning electric motor 21 as a motor operation element via an inverter 20 as a motor generator control unit.
- the resolver 22, the mechanical brake 23, and the turning transmission 24 are connected to the rotation shaft 21 ⁇ / b> A of the turning motor 21.
- the pilot pump 15 is connected with the controller 26 via the pilot line 25.
- the turning electric motor 21, the inverter 20, the resolver 22, the mechanical brake 23, and the turning transmission 24 constitute an electric turning system as a load drive system.
- the operating device 26 includes a lever 26A, a lever 26B, and a pedal 26C.
- the lever 26A, the lever 26B and the pedal 26C are connected to the control valve 17 and the pressure sensor 29 via hydraulic lines 27 and 28, respectively.
- the pressure sensor 29 is connected to a controller 30 that performs drive control of the electrical system.
- the tilt sensor M1 is an example of a slope detection unit that detects that the hybrid shovel is positioned on a slope.
- the tilt sensor M1 is an acceleration sensor mounted on the upper swing body 3, detects the tilt angle of the upper swing body 3, and outputs the detected value to the controller 30.
- the heat consuming unit 40 is a functional element for consuming, as heat, the regenerative power generated by the turning motor 21 when the turning is stopped.
- the heat consuming unit 40 includes an electric resistance unit 40a and a flow control valve 40b.
- one of the electric resistance part 40a and the flow control valve 40b may be abbreviate
- the electrical resistance unit 40a includes a changeover switch and an electrical resistance.
- the changeover switch is a switch that switches between conduction and interruption between the inverter 20 and the electrical resistance in accordance with a control signal from the controller 30. Then, the electric resistance portion 40a brings the inverter 20 and the electric resistance into conduction in response to the control signal from the controller 30, and accepts the regenerated electric power generated by the turning motor 21 when the turning is stopped as the DC power to the electric resistance.
- the electrical resistance receives regenerative power to generate heat. As described above, the electric resistance unit 40a can consume the regenerative power as heat, thereby reliably using the regenerative power generated by the turning motor 21.
- the flow control valve 40 b is a valve capable of controlling the flow rate of the hydraulic fluid discharged by the main pump 14.
- the flow rate control valve 40 b restricts the flow rate of the hydraulic fluid discharged by the main pump 14 in accordance with the control signal from the controller 30 to increase the discharge pressure of the main pump 14 and hence the absorption horsepower.
- the flow rate control valve 40 b generates pressure loss by generating a heat by limiting the flow rate of the hydraulic fluid discharged by the main pump 14.
