Problems solved by technology

These mechanized equipment still need manual operation at the wellhead, the labor intensity is very high, the safety of the operators cannot be effectively guaranteed, and the labor cost also increases accordingly
As far as the above-mentioned equipment itself is concerned, the connection and disassembly of drilling tools is slow, which directly affects the efficiency of drilling and workover; at the same time, these equipments are suitable for a narrow range of drilling tools, and the pressure plate and equipment need to be replaced repeatedly during the operation, so that It is more inconvenient to connect, dismantle and repair the drilling tools

Abstract

The invention discloses an iron driller. The iron driller comprises a rotating translational stretching mechanism and a tongs assembly. The tongs assembly is composed of a support, back tongs, main tongs and spinning tongs; the rotating translational stretching mechanism is composed of a base, a rotating device, a translation device and a support arm assembly; one end of the support arm assembly is connected with the support and the other end of the support arm assembly is connected with the translation device which is connected with the base through the rotating device; the main tongs, the back tongs and the spinning tongs are connected with the support; the main tongs positioned above the back tongs are hinged to the back tongs; and the spinning tongs are mounted above the main tongs and the back tongs. By the aid of the iron driller, the automation of the overall process of attaching and detaching drilling tools is achieved, the automation level of drilling and repairing wells is improved, and the working efficiency and security are improved.

Description

technical field [0001] The invention relates to a drilling tool connection or disassembly device used for drilling and workover, in particular to an iron driller. Background technique [0002] At present, in oil drilling and workover operations, the connection and disassembly of drilling tools during the tripping process is basically done manually with the help of some mechanized equipment, such as hydraulic tongs, cat heads, pneumatic spinners, etc. . These mechanized equipment still need to be manually operated at the wellhead, which is very labor intensive, the safety of the operators cannot be effectively guaranteed, and the labor cost also increases accordingly. As far as the above-mentioned equipment itself is concerned, the connection and disassembly of drilling tools is slow, which directly affects the efficiency of drilling and workover; at the same time, these equipments are suitable for a narrow range of drilling tools, and the pressure plate and equipment need t...
