Novel drill pipe shackle assembling and centering device

Abstract

The invention belongs to the field of petroleum equipment, and particularly relates to a novel drill pipe shackle assembling and centering device. The device is characterized in that hydraulic cylinders of two centering device bodies push a connecting rod to move, and drive a centering tank to clamp and fix drill pipes; the centers of the to-be-connected drill pipes are aligned by guiding of a centering tank horn mouth, then the centering tank is retracted, and hydraulic power tongs are used for assembling shackle. The centering tank clamps and fixes the drill pipes, the centering tank horn mouth is used for guiding centering, and the device can be of an integrated structure or a split structure. The height of the centering tank can be adjusted through springs so that various adjustment modes of the springs, air cylinders, the hydraulic cylinders, lead screws and the like can be used. In order to guarantee the clamping accuracy and the movement stability of the centering tank, a guiderail is arranged on the movement track of the centering tank, and wheels are arranged on the lower side of the centering tank to move along the guide rail. The device is convenient, stable and reliable to use, high in working efficiency, and capable of reducing the labor intensity of workers and greatly improving the safety of operators.

Description

technical field [0001] The invention belongs to the field of petroleum equipment, and in particular relates to a novel drill pipe make-up centering device, which is used for the drill pipe centering of the drill pipe make-up during drilling. Background technique [0002] In drilling and workover operations, the traditional method is manual make-up and break-in, and manual centering of the drill pipe is required to make-up and make-up, which is labor-intensive and dangerous. At present, more and more automatic tools and tools are used in drilling and workover operations, and it has become a trend to configure automatic operation equipment. However, the make-up of drill pipes still requires manual alignment of the two drill pipes, and then hydraulic tongs or iron drillers. Buckle-up is labor-intensive and has a high risk factor. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems, and provides a novel drill pipe make...
