Embodiment 1

[0046] Such as figure 1 , 2 Among them, an intelligent full power mechanism, including the electric drive body 2, and is provided with a power management system 3 on the electric drive body 2. The power supply management system 3 is electrically connected to the drive motor 6, and the drive motor 6 is connected to the hydraulic station 4. There is also a winch assembly 5. There are two driving methods of winch, including driving motor 6 direct drive and hydraulic drive, using a drive motor 6 direct drive on a small device, in large equipment, such as hydraulic clamp main clamp A well-formed machine in diameter 73 to 141 mm is hydraulically driven.

[0047] Such as figure 1 In the electric drive body 2, there is also a well grid base 32, and the top portion of the wellboil base 32 is hinged, and the tail of the electric drive body 2 is also connected to the work platform 22;

[0048] Such as image 3 , 4 In, the wellbore base 32 is provided with an intelligent hydraulic clamp 1 (sma...

Abstract

The invention provides an intelligent all-electric workover rig which comprises an electric drive vehicle body, a power management system is arranged on the electric drive vehicle body, the power management system is electrically connected with a drive motor, and the drive motor is connected with a hydraulic station; a derrick foundation is further arranged on the electric drive vehicle body, the top of the derrick foundation is hinged to the derrick assembly, and the tail of the electric drive vehicle body is further connected with the operation platform. An intelligent hydraulic clamp capable of stretching out and drawing back to the position above the operation platform is arranged on the derrick foundation. By adopting the scheme of the intelligent hydraulic clamp, the position between the intelligent hydraulic clamp and the tubular column can be automatically adjusted, and accurate positioning between the hydraulic clamp and the tubular column is achieved. The arranged intelligent rod can control the intelligent hydraulic clamp to slow down when approaching the tubular column, so that the normal running speed can be increased, and mechanical impact is reduced. And the side pushing foundation and the side pushing arm are arranged, so that the position of the electric driving vehicle body can be further accurately adjusted, and the positioning between the operation platform and other auxiliary tools and the tubular column can be accurately adjusted.

Description

Technical field [0001] The present invention relates to the field of well-operators in the oil and gas field development apparatus, especially an intelligent full-electric coaster. Background technique [0002] The welling machine is the main device for repairing the development of the well-developed oil well, which is the improvement and decentralization of the oil tube in the oil well. In a well-operated machine suitable for small well field, the body structure is usually used as the basis for the wellting platform. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, But under this condition, the work platform is difficult to align with the wellhead. The hydraulic clamp is a tool for the tubular buckle or unloading, which is usually capable of intensive the stretching operation, and the hydraulic clamp is difficult to hold the pillar in the working platform and the wellhead, the hydraulic clamp is difficult to hold. A fully autom...
