Problems solved by technology

[0002] At present, in domestic drilling and workover operations, dual-purpose tongs can be used when connecting drill pipes and running casings. The general-purpose dual-purpose tongs use transfer cylinders to transfer between the working position and the non-working position. Faster, the stroke range is not easy to control, and it is easy to hit the drill pipe, causing damage to both the pliers and the drill pipe

Abstract

The invention discloses a rotatable transfer track device for dual-purpose tongs, which includes an I-shaped movable transfer track, a mobile gearbox is arranged in the track of the movable transfer A hydraulic motor is installed on the side, and a dual-purpose tong boom is installed below, and the hydraulic motor is connected to the control box through the assembly plate. The moving speed of the dual-purpose tongs on the track can be set arbitrarily, and can stop at any position without colliding with the drill pipe.

Description

technical field [0001] The invention relates to the field of oil drilling, in particular to a rotatable transfer rail device for dual-purpose tongs. Background technique [0002] At present, in domestic drilling and workover operations, dual-purpose tongs can be used when connecting drill pipes and running casings. The general-purpose dual-purpose tongs use transfer cylinders to transfer between the working position and the non-working position. Faster, the stroke range is not easy to control, and it is easy to hit the drill pipe, causing damage to both the pliers and the drill pipe. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a rotatable transfer track device for dual-purpose tongs. When the dual-purpose tongs move on the track, the transfer speed and stroke range can be controlled by the control system. . [0004] In order to achieve the above-mentioned technical pur...
