A large-torque downhole rod and pipe tool removal and installation device

Abstract

The invention discloses a high-torque down-hole rod pipe tool detaching-assembling device. A base assembly is provided with a pushing-pulling assembly, a pushing-pulling supporting assembly, a quick rotating assembly, a fixing clamping assembly, a moving clamping assembly and a moving material supporting assembly from left to right in sequence. A bottom plate assembly, an electric control box assembly and a hydraulic station assembly are fixed on the ground. An electric control box controls a hydraulic station, so that the fixing clamping assembly and the moving clamping assembly carry out clamping and rotating buckling on a workpiece, the pushing-pulling assembly carries out pushing and pulling on the workpiece, and the quick rotating assembly clamps a rotary impact thread buckle and then carries out quick unscrewing or screwing on a thread. Synchronous clamping mechanisms of the fixing clamping assembly and the moving clamping assembly use three-cylinder centering clamping and three-cylinder fixing clamping modes. The high-torque down-hole rod pipe tool detaching-assembling device is simple in structure and convenient to use, rotating buckling torque is large, centering is accurate, operation is stable, and the device can be suitable for various down-hole rod pipe tools with different diameters.

Description

technical field [0001] The invention belongs to a centering dismounting device for downhole rod and pipe tool threads of petroleum machinery, and in particular relates to a large moment downhole rod and pipe tool dismounting and installing device. Background technique [0002] In recent years, with the increasing demand for oil resources, my country has accelerated the development of drilling technology, which has promoted the development and application of downhole rod and pipe tools. Among them, the high-torque downhole rod and pipe tool removal and installation device is mainly used as an indispensable tool in the process of unscrewing and assembling various screw drilling tools and other types of downhole rod and pipe threaded connectors. For a long time, in the disassembly and assembly equipment of downhole tools in my country, the phenomenon that the torque is small during the disassembly process, cannot be disassembled, the buckle is damaged during the disassembly pro...
