Abstract

The invention provides an iron roughneck used for petroleum well workover, and relates to auxiliary equipment in petroleum well workover. The iron roughneck used for the petroleum well workover comprises a hydraulic tong assembly, a swingable swing delivery assembly and a clamping mechanism for supporting the swing delivery assembly, the clamping mechanism is provided with a clamping body, the clamping body is a Y-shaped plate and comprises two fixing ends and an installing end, the upper surfaces of the fixing ends are provide with upward convex positioning columns, the upper surface of the middle part of the clamping body is further provided with a locking device for locking the clamping body to the wellhead flange, a swing delivery assembly is installed on the installing end, and the hydraulic tong assembly is arranged on the swing delivery assembly. The invention aims to provide the iron roughneck used for the petroleum well workover. The iron roughneck used for the petroleum well workover can be integrally clamped on the wellhead flange, and the iron roughneck can be further applied to well workover jobs of a well-drilling-free platform.

Description

technical field [0001] The invention relates to auxiliary equipment in oil well workover, in particular to an iron driller for oil well workover. Background technique [0002] The iron driller originated from the field of oil drilling. It is a semi-automatic auxiliary operation equipment used in the drilling system for tripping and unloading pipe string threads. It can complete the rotary connection of drilling tools such as drill pipes and casings. , is currently the most advanced torque turnbuckle equipment. Iron drillers are mainly composed of manual auxiliary devices and hydraulic tongs. Because they can partially replace part of the manual operation and reduce the labor intensity of workers, they are called iron drillers. [0003] The iron driller has changed the working principle of the traditional tongs, and is a multifunctional, safe and efficient drilling tool spinner. The iron driller divides the make-up, breakout and fastening and punching work into two parts. T...
