Abstract

The invention belongs to the field of petroleum equipment, in particular to an automatic workover rig. The automatic workover rig is composed of a novel drilling equipment conveying device, a drilling-platform-surface mechanical arm, drilling-platform-surface automatic hydraulic forceps, automatic power slips, a novel drill rod screwing-on and alignment device, a racking-platform mechanical arm,a racking-platform foldable handrail, an automatic elevator, a runner wagon and a lifting ring anti-oscillation device. Each matched device and system are connected with a control system respectivelyand integrated at the position of a driller for centralized control, the driller is monitored in the whole operation process, unmanned operation of pipes in going up to or going down from a drilling platform is achieved, the matched automatic operation of alignment and screwing-on of drill rods is achieved through the drilling-platform-surface automatic hydraulic forceps, and the runner wagon andthe lifting ring anti-oscillation device achieves transferring of the drill rods between the automatic power slips and the racking-platform mechanical arm through a centering lifting ring. To sum up,the automatic workover rig reduces the labor intensity of operation personnel, improves the work efficiency, and is safe and reliable.

Description

technical field [0001] The invention belongs to the field of petroleum equipment, and in particular relates to an automatic workover machine, which is used to realize the automation of workover operations. Background technique [0002] In drilling and workover operations, the traditional method is to use traveling block hooks, hydraulic tongs, tongs, elevators, etc., and cooperate with several operators on the second floor and the drilling floor to complete the workover operations. The operating environment is harsh and the operation The process is labor-intensive, requiring the tacit cooperation between the driller and the operators at each position, and the operation is highly dangerous. At present, more and more automation tools are used in drilling and workover operations, and the automation of workover process has become a trend. Reducing the number of workers in workover operations, reducing labor intensity and operational risk, realizing the centralized control of th...
