Embodiment 1

[0026] Embodiment one: if figure 1 As shown, the external power supply type electric construction machinery includes movable power supply vehicles and electric construction machinery. The movable power supply vehicle is driven by external equipment traction. The electric construction machinery is a common excavator. The movable power supply vehicle includes a movable car body 1 , the vehicle body 1 is equipped with a power supply device 2 and a cable retractable device 3; the electric engineering machinery includes a freely movable engineering vehicle body 6, and the engineering vehicle body 6 is provided with a motor, a power control device 7, an operation control center 8 and a receiving machine. The electric arm 5 and the electric receiving arm 5 can freely rotate up and down, left and right, and elastic devices are arranged to support the weight of the electric receiving arm 5 and the cable 4 in the direction of vertical rotation.

[0027] Wherein, the external structural ...

Embodiment 2

[0035] Embodiment two: if figure 2 As shown, the difference from Embodiment 1 is that the mobile power supply vehicle in the externally powered electric engineering machinery is independently driven by the power generated by the power supply device 2, that is, the battery. Specifically, the movable vehicle body 1 is an electric vehicle, and its motor The electric power of the electric vehicle comes from the storage battery. The control system of the electric vehicle is connected with the signal receiving transmitter a2.1, which can transmit the power required to control the output of the inverter, and the battery power, temperature and other information can also be transmitted through the signal receiving transmitter a2.1 Transmission to the control system of electric vehicles.

[0036] In addition, in addition to the battery structure in the above two embodiments, the power generating device of the power supply device 2 of the present invention can also be a generator, such ...

Abstract

The invention provides externally-powered electric engineering machinery. The externally-powered electric engineering machinery comprises a mobile power supply vehicle and an electric engineering machine. The mobile power supply vehicle comprises a mobile vehicle body. A power unit and a cable take-up and pay-off device are mounted on the vehicle body. The electric engineering machine comprises an engineering vehicle body capable of moving freely, wherein an electric motor, a power control device, an operation control center and a power collection arm are arranged in the vehicle body. By adopting the externally-powered electric engineering machinery, the problem of cable connection between power supply equipment and electric equipment when electric engineering machinery moves to work is solved; it is guaranteed that cables do not hinder free movement of the electric equipment within a certain scope, and reliable electric power supply is guaranteed; and the externally-powered electric engineering machinery is good in work rotation capability and high in environmental adaptability, and the advantages are more obvious in working regions with oil and gas shortage. Meanwhile, the power supply equipment and the electric equipment can conduct signal communication, and use safety of the cables is ensured.

Description

technical field [0001] The invention belongs to the technical field of construction machinery equipment, and relates to construction machinery technology, communication technology and control technology of an externally powered electric construction machine. Background technique [0002] Traditional mobile vehicles such as construction machinery and automobiles generally have the disadvantages of relying on oil resources and causing heavy pollution. Electrification has become an important development direction of mobile vehicles. In addition, in some special areas of our country, the power resources are particularly abundant, and the electricity price is very cheap. Using electric vehicles is not only convenient and reliable, but also greatly reduces energy consumption and operating costs. As my country's urban construction becomes more and more mature, electric vehicles with convenient power supply, household use, small and micro engineering use, or other special occasions...
