AI Technical Summary

Technical Problem

The existing walking device for oil drilling iron drills occupies a large space, leading to decreased work efficiency and increased equipment wear and tear.

Method used

A traveling device is designed, comprising a traveling frame, a drive mechanism, and a traveling mechanism. The iron drill is mounted on the traveling frame, and the traveling mechanism consists of relatively parallel guide rails and roller units. The roller units are embedded in the guide rails. The drive mechanism drives the traveling frame to move along the guide rails, and the iron drill can extend or retract outside the guide rails to ensure stability and reliability.

Benefits of technology

It effectively frees up wellhead space, reduces collision risks, improves operational efficiency, reduces equipment wear and tear, and enhances operational stability and reliability.

Abstract

The utility model relates to the technical field of petroleum and natural gas drilling, in particular to a walking device for a petroleum drilling iron roughneck. The walking device comprises a walking frame, a driving mechanism and a walking mechanism, the iron roughneck can be installed on the walking frame, and the iron roughneck is installed at the front end of the walking frame through a connecting piece. The rolling surface of the first roller unit is in rolling contact with the lower surface of the inner side of the guide rail, and the rolling surface of the second roller unit is in rolling contact with the upper surface of the inner side of the guide rail, so that the forward tilting moment generated by an iron roughneck can be effectively balanced, smooth movement of the walking frame is ensured, the jamming phenomenon is avoided, and the running stability and reliability of the walking device are greatly improved. According to the walking device for the petroleum drilling iron roughneck, the iron roughneck can be installed at the front end of the walking frame, when the driving mechanism drives the walking frame to move to the far end along the guide rail, the iron roughneck on the walking frame stretches out of the far end of the guide rail, the iron roughneck can retract into the guide rail when the iron roughneck is in a standby state, and the wellhead space is effectively released.
