Petroleum drilling and production equipment, manipulator on the drilling floor and pulley mechanism

Abstract

The invention discloses a pulley mechanism which comprises a first rail and a first trolley. The first trolley can slide along the first rail. A second rail intersects with the first rail. The first trolley is provided with a second trolley. A telescopic oil cylinder is arranged between the second trolley and the first trolley. The two ends of the telescopic oil cylinder are hinged to the first trolley and the second trolley respectively. One of the second rail and the second trolley is provided with a guide rail. The other one of the second rail and the second trolley is provided with a sliding groove matched with the guide rail. According to the pulley mechanism, the double rails and a double-layer trolley structure which can be automatically combined and disengaged are arranged, demounting is not needed, manual intervention is not needed, a mechanical arm can be conveniently and rapidly withdrawn from a well mouth, and the interference caused by other construction operation near the well mouth when an original mechanical arm is parked on the rails is reduced as much as possible.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a pulley mechanism, a drill floor manipulator and oil drilling equipment provided with the pulley mechanism. Background technique [0002] Wellhead automation and unmanned is the development direction of petroleum equipment. The manipulator on the drilling floor is a major wellhead automation equipment. It usually cooperates with the manipulator on the second floor to replace the operator on the drilling floor to complete the handling of the pipe string between the wellhead and the pipe rack. It can also assist the iron driller during the drilling process. Complete the centering operation when the pipe string is buckled. [0003] The manipulator on the drill floor generally includes a pulley mechanism, a mechanical arm and a pipe string support mechanism. The pulley mechanism is installed on the drill floor, and the bottom of the mechanical arm is set on the pulley mechanism; ...

AI Technical Summary

Problems solved by technology

Since the drill floor manipulator usually works on the drill floor between the wellhead and the rack, its track is usually set near the wellhead, which brings a trouble, that is, when the drill floor manipulator is not working, the robotic arm is parked on the On the track, it occupies the precious space near the wellhead, which interferes with other construction operations on the drill floor, such as conveying the pipe string up and down the drill floor through the power catwalk, and affects its normal work. To eliminate this interference, the only way to The mechanical arm is removed, and the mechanical arm is reinstalled when the manipulator on the drill floor needs to work. The operation is extremely complicated and cumbersome
