The oil production truck mainly comprises a vehicle-mounted chassis, a reduction gearbox, a winch, a derrick and the like. The traditional oil production vehicle is loaded by a chassis of a second type vehicle, and the power for walking and oil production operation is provided by a chassis engine (fuel oil). When the operation is needed, the vehicle is driven to a well to be operated to extract oil, the space of an oil well site is enough for the oil extraction vehicle to enter, turn around and the like, and only one well can be operated at a time. The engine has high noise and high oil consumption during working, so the traditional product has low working efficiency, and is not energy-saving and environment-friendly.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide the electric rotary oil bailing vehicle which is high in working efficiency, energy-saving and environment-friendly.
The technical solution of the utility model is as follows: the rotary oil fishing vehicle is characterized by comprising an oil extractor which is arranged on a lifting crane type rotary supporting device.

For ring wells (with a plurality of well heads and arranged in a circumference), foundations are laid on the oil field site, and each well is arranged in a circumference mode by taking the foundations as centers. The oil extraction device is organically combined with a driving rotating device of the hoisting crane, so that the oil extraction device can rotate on the ground fixed basis, the oil extraction operation of a plurality of wells can be completed by rotating the oil extraction device for a certain angle once, the well is directly fished again after the fishing, the oil extraction device only needs to rotate for a certain angle without moving, and the operation concentration efficiency is greatly improved. After the operation is finished, the oil extraction device is stopped at a well site, the oil extraction device does not need to be driven back to an operation team, and only the operation personnel need to drive the trolley to go to the oil extraction device when the operation is needed, so that unnecessary runway time is saved. Meanwhile, the power of the oil extraction device is changed into the driving of a motor, the oil extraction device is connected with the field power grid of the oil field for operation, and the noise is very low during operation.
The utility model has the advantages that: 1. the rotation of the oil extraction device is controlled by the driving rotary supporting device of the transport hoisting crane, the speed is stable, the brake is reliable, and the hoisting machine is also applied to petroleum machinery for the first time. 2. The whole machine is flexible and reliable in rotation, and is more convenient for aligning the wellhead.
