Embodiment 1
[0064] see Figure 1-6 , this embodiment provides a dual-mode drive electric excavator, which can be applied in various excavation environments and meet different power supply conditions. The dual-mode drive electric excavator can realize two modes of operation, in one mode, the electric energy provided by the external three-phase power supply 9 is used, and in the other mode, the electric energy stored in itself is directly used . Wherein, the dual-mode drive electric excavator includes an excavator body 1, a hydraulic system 2, a power output system 7, an energy system 6, a switching device and a programmable controller.
[0065] read on figure 1 , the excavator body 1 includes a working device 3 and a traveling device 4 , and in this embodiment, it also includes a cab 8 , a slewing device 5 , an on-board electrical appliance 19 and a voltage conversion module 18 . The working device 3 is used to excavate the excavated objects, and the traveling device 4 is used to drive ...
Embodiment 2
[0083] This embodiment provides a dual-mode drive electric excavator, which is similar to the excavator in Embodiment 1, except that the structures of the working device 3 and the traveling device 4 are different.
[0084] The working device 3 includes a bucket, a robot arm, and a displacement sensor. The mechanical arm is connected to the bucket and is used to drive the bucket to excavate the excavated material. The displacement sensor is installed on the mechanical arm and is used to detect the displacement of the bucket relative to the mechanical arm. When the displacement is lower than a preset displacement value, the working device 3 generates a non-excavation signal, otherwise an excavation signal is generated. Therefore, each signal generated by the working device 3 is converted by the signal detected by the displacement sensor, and the detection accuracy of the displacement sensor is very high, which can ensure the timeliness and accuracy of the signal generated by th...
Embodiment 3
[0087] This embodiment provides a dual-mode drive electric excavator, on the basis of Embodiment 1, an electric power detection device is added, and the functions of the programmable controller are also increased. The power detection device is used to detect the storage capacity of the storage battery pack 16 , which can detect the storage capacity by detecting the voltage of the storage battery pack 16 or the like. Wherein, the programmable controller 14 is also used for judging whether the storage capacity is lower than a preset power; when the storage capacity is lower than the preset power, the programmable controller 14 judges whether the battery pack 16 inputs electric energy to the electric energy motor 13; When the group 16 inputs electric energy to the electric energy motor 13, the programmable controller 14 first stops the storage battery pack 16 from inputting electric energy to the electric energy motor 13, and drives the power supply cable to input electric energy ...
