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 speed of connecting and dismounting the 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 cannot adjust the make-up and breakout torque and breakout torque according to real-time conditions. stroke, the thread of the drilling tool is greatly damaged, and as a result, it needs to be replaced frequently, which makes the connection, disassembly and maintenance of the drilling tool more inconvenient

Abstract
The invention discloses an iron roughneck. The iron roughneck comprises a rotary bracket, a pair of buckle collapsing pliers and a spinning wrench. The rotary bracket comprises a stand column, an L-shaped bracket body, a rotating base, a rotating gear and a lifting hydraulic cylinder. The pair of buckle collapsing pliers comprises a rotating shaft assembly, a hydraulic clamping pliers assembly, a rotating shaft base, a rotating hydraulic cylinder assembly and a rotating and guide pushing hydraulic cylinder assembly. The spinning wrench comprises a support, a first rocker arm, a second rocker arm, a first connecting frame rod, a second connecting frame rod, a first roller wrench assembly, a second roller wrench assembly, a clamping hydraulic cylinder, a first balancing connecting rod, a second balancing connecting rod and a balancing pin roll. Compared with the prior art, the iron roughneck is complete in function, compact in structure and high in automation degree, saves manpower, lowers production cost, enables buckle assembly and buckle disassembly to be mechanized, improves the working efficiency, and meanwhile can further adjust the buckle assembly and disassembly torque and buckle assembly and disassembly thread travel compensation, protect drill rod threads, and reduce the frequency of equipment replacement and maintenance.
Description
technical field [0001] The invention relates to the technical field of drilling rigs, in particular to an iron driller used for drilling or repairing wells. 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 speed 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 cannot adjust the make-up and break-out...
