The invention relates to the technical field of oil field wellhead operation devices, and particularly discloses an automatic wellhead operation device for a sucker rod, which comprises a manipulator, the manipulator comprises a connecting seat, a V-shaped folding arm group and a stand column outer cylinder, and the front end and the rear end of the V-shaped folding arm group are respectively connected with the connecting seat and the stand column outer cylinder; a first hydraulic cylinder for driving the V-shaped folding arm set to be opened and closed is installed at the front end of the stand column outer barrel, a first hydraulic clamp is detachably hung below the connecting base, a buckling device and a second hydraulic clamp are installed above the connecting base, and an overturning hanging ring, an elevator and a power slip which are matched with the mechanical arm to work are further arranged in front of the mechanical arm. Through cooperation of all the mechanisms, operation of lifting and lowering the sucker rod can be achieved, the mechanization degree in operation is high, and compared with an existing manual assistance operation mode, the automation degree is higher, efficiency is improved, and personnel operation safety is better.
Description
technical field [0001] The invention relates to the technical field of oilfield wellhead operation devices, in particular to an automatic wellhead operation device for sucker rods. Background technique [0002] Workover operation is the most common form of operation in oil fields. At present, the entire operation process of sucker rods is mainly manual, with manual make-up and break-out, and a small amount of special-purpose sucker rod make-up and break-out clamps are used. The work intensity is high and the working environment is harsh. As oilfields urgently need to reduce the labor intensity of operators, improve operation safety, and improve work efficiency, the market demand for operation automation tools is increasing day by day. Therefore, the design of products is becoming more and more safe, reliable, easy to operate, and It is developed on the characteristics of easy maintenance, durable leather and so on. [0003] At present, the manipulator designed by our compan...
