Problems solved by technology

[0003] However, imported iron drills are expensive, and the iron drills developed in the early stage in China have deficiencies whether they are telescopic arm type or track type. For example, the telescopic arm type iron drillers cannot provide large pipe diameter, high torque, and large space because of their compact structure. Range operation, positioning accuracy is not ideal in adapti

Embodiment

[0044] This example provides an iron driller, see figure 1 , which includes a track 1, a walking frame 2, a lifting frame 3, a tilting mechanism, a back clamp 5, a punching clamp 6, a spin clamp 7 and a control system. Back-up tongs 5 ​​, punching tongs 6 and twisting tongs 7 are sequentially arranged on the lifting frame 3 along the direction from bottom to top. The control system is used to control the work of the iron driller.

[0045] The track 1 can be installed on the wellhead platform by bolts, and the length of the track 1 can be set according to the needs of the site, so that the track 1 spans the wellhead and the mouse hole. And limit stoppers (not shown) can be set at both ends of the track 1 to limit the range of motion of the walking frame 2 .

[0046]The walking frame 2 can move forward, stop or return to a certain position along the track 1 through the walking mechanism. Wherein, the track 1 includes two guide rails arranged in parallel, and the inner side of...

Abstract

The invention discloses an iron roughneck, and belongs to the technical field of oil drilling and well workover. The iron roughneck comprises a track, a walking frame, a lifting frame, a tilting mechanism, a back-up wrench, a punching and buckling wrench and a spinning wrench. The walking frame can move forwards, stop or return along the track through a walking mechanism. The lifting frame can belifted relative to the walking frame through a lifting mechanism, and the lifting frame can tilt relative to the walking frame through a tilting mechanism. The lifting frame comprises a tilting oil cylinder and a rotating frame, wherein the rotating frame is rotatably connected with the lifting frame, one of a cylinder body and a piston rod of the tilting oil cylinder is rotatably connected with the lifting frame, and the other of the cylinder body and the piston rod of the tilting oil cylinder is rotatably connected with the rotating frame. The back-up wrench, the punching and buckling wrenchand the spinning wrench are sequentially arranged on the lifting frame from bottom to top. According to the iron roughneck, the lifting frame of the iron roughneck can be tilted, after the track crosses a wellhead and a mouse hole, the iron roughneck can walk to two places for direct operation, and the practicability is wide.

Description

technical field [0001] The invention relates to the technical field of oil drilling and workover, in particular to an iron driller. Background technique [0002] Iron driller is a multi-functional, safe and efficient pipe spinner operation equipment. During drilling and workover operations, the drilling tools, tubing, Casing making, breaking out and other operations are very important auxiliary equipment in automatic drilling and workover. The field of oil drilling has long been popularized in developed countries in Europe and the United States, but the research and manufacture of iron drillers in China is still in its infancy. Some drilling sites have begun to use iron drillers to replace manual lifting tongs and hydraulic-gas hybrid tongs to improve drilling production. Improve efficiency and operation safety, reduce the labor intensity of operators. [0003] However, imported iron drills are expensive, and the iron drills developed in the early stage in China have defic...
