Automatic treatment assembly for top drive pipe

Abstract

The invention provides an automatic treatment assembly for a top drive pipe, which comprises a torque arm assembly, a back-up tong assembly, a blowout preventer assembly, an inclining mechanism, a rotator assembly, a hydraulic elevator and a hydraulic manifold. The automatic treatment assembly is characterized in that the upper end of the rotator assembly is connected with a gearbox and is independent from a spindle when moving; the torque arm assembly, the back-up tong assembly, the blowout preventer assembly, the inclining mechanism, the hydraulic elevator and the hydraulic manifold are hung under a rotating head, and move clockwise and anticlockwise together with the rotating head, and round trip operation service of petroleum drilling can be finished conveniently, safely and efficiently; and functions that in a petroleum drilling process, drill pipes are gripped and released automatically, fastening and unfastening is carried out automatically, an inner blowout preventer is remotely controlled to close a channel in a drill string when in blowout, fastening and unfastening can be realized by a motor at an optional height, and the like are effectively realized.

Description

technical field [0001] The invention relates to an automatic processing device for drill rods of a top drive drilling system in petroleum equipment. Background technique [0002] At present, during the construction process of various domestic oil drilling rigs, most of the drill pipes are loaded and unloaded by manual operation, which is not only inefficient, but also poses hidden dangers to the safety of operators. In view of this situation, an automatic drill pipe handling device for the top drive drilling system is proposed; and its mechanical structure and hydraulic system are designed; and the top drive drilling system represents a most advanced oil drilling driving method. Because the drill pipe is long and heavy, it is not suitable to move, and several workers need to work together to complete the pipe change, which requires a lot of labor intensity; this prolongs the drilling operation time to a large extent and reduces the construction efficiency. At the same time,...

AI Technical Summary

Problems solved by technology

Because the drill pipe is long and heavy, it is not suitable to move, and several workers need to work together to complete the pipe change, which requires a lot of labor intensity; this prolongs the drilling operation time to a large extent and reduces the construction efficiency

At the same time, due to the limitation of the working environment of the drilling rig, especially in the process of high-level drilling and inclined drilling, it is particularly difficult to manually load and unload the drill pipe, and workers may cause major construction casualties due to momentary negligence during operation.
