Description

Technical Field

[0001] The invention belongs to the technical field of oil drilling equipment manufacturing, and in particular relates to a power catwalk drill string lifting guide rail and a manufacturing method of the guide rail. Background Art

[0002] The horizontal power catwalk is an automated equipment suitable for offshore platforms to complete pipe transportation operations such as drill pipes, drill collars, and casing. It adopts an integrated mechanical, electrical, and hydraulic design, and realizes bidirectional transportation of pipes between the ground pipe arrangement area and the drilling platform area through the drill string lifting device and the pulley. The drill string lifting device is mainly composed of a trolley, a guide rail, an adjustment device, an integrated loading and unloading arm, a tensioning mechanism, upper and lower sprocket shafts, a chain, a motor reducer assembly, etc. It is usually arranged on the right side of the catwalk body (facing the drilling rig direction), and is driven by an independent hydraulic motor to drive the sprocket, roller chain to pull the trolley, the adjustment device and the integrated loading and unloading arm to slide synchronously in the guide rail to realize bidirectional transportation of the drill string between the ground pipe arrangement area and the high-level work surface of the catwalk.

[0003] In the drill string hoisting device, the trolley slides within the "[]"-shaped trough of the guide rail. The clearance between the slider and the guide rail trough is small to ensure the trolley slides smoothly within its travel range. During the manufacturing process, if the method of welding and then machining the entire piece is used, the small opening dimension L of the guide rail "[]"-shaped trough cannot be extended into the trough by the right-angle milling head, making it impossible to machine the entire piece. If conventional methods are used for direct welding, the opening dimension L and relative position between the left "["-shaped trough and the right "]"-shaped trough cannot be guaranteed due to welding deformation.
