Pipe setback

Abstract

The invention provides a pipe setback, and relates to the technical field of oil field drilling machine equipment. The pipe setback is used for a drill rod three-joint unit and comprises a frame, a plurality of assembly type cross bar assemblies and a plurality of carbonized sleepers. The multiple assembly type cross bar assemblies are rotationally connected to the frame and detachably arranged relative to the frame, the multiple carbonized sleepers are detachably installed on the frame, the assembly type cross bar assemblies and the carbonized sleepers are arranged alternatively, the assemblytype cross bar assemblies form a guide arc face used for guiding a drill rod to the carbonized sleepers, and the carbonized sleepers are used for bearing the drill rod. The pipe setback provided by the invention can avoid direct steel-to-steel contact between the drill rod and the pipe setback, protects a screw threads of the drill rod, and is easy to clean, easy to maintain and simple in structure

Description

technical field [0001] The invention relates to the technical field of oil field drilling rig equipment, in particular to a stand box. Background technique [0002] In the oil industry, the stand boxes on the base platform of traditional drilling rigs are generally made of sleepers stacked into a rectangle, with rubber pads laid on them, and drill pipe stands are placed. For the existing manipulator technology for pipe arranging on the drilling floor, the traditional stand box cannot play the role of guiding the stand of the drill pipe and assisting the positioning of the stand when the manipulator arranges the pipe. In addition, in the low temperature freezing weather, the rubber pads laid on the table have no fixing device, which may easily cause the rubber pads to slip or the drill pipe stand to slide sideways, which will bring safety hazards to the drilling stand pipe arrangement.

AI Technical Summary

Problems solved by technology

For the existing drilling floor manipulator technology, the traditional stand box's "flat" stand box cannot play the role of guiding the drill pipe stand and assisting the stand positioning when the manipulator arranges the pipe.

And for low-temperature freezing weather, the rubber pad laid on the table has no fixing device, which may easily cause the rubber pad to slip or the drill pipe stand to slide sideways, which will bring safety hazards to the drilling stand pipe arrangement work

[0003] In the prior art, the utility model patent CN208619065U provides a new type of metal stand box, but the stand box will cause the stand box to have no buffer device, and the drill pipe and the stand box will be in contact with "steel against steel" when the pipe is arranged, which is very easy to cause drilling. Damaged rod thread

The large round tubes and the small round tubes are arranged tangentially in pairs. If the assembly type is placed directly, there is no fixing device, and the gap between the two tangent round tubes rolls to cause the gap to be indeterminate.

If it is fixed by welding, the welding of the round pipe will easily cause the overall welding deformation, and the mud in the gap of the round pipe is difficult to clean
