Petroleum machinery mounting drilling tool and mounting method thereof

Abstract

The invention discloses a petroleum machinery mounting drilling tool and a mounting method thereof. The petroleum machinery mounting drilling tool comprises a drill rod, wherein an inserting groove isformed in the upper portion of the drill rod, a drilling machine head is movably connected into the inserting groove in an inserted mode, and a movable groove is formed inside the drilling machine head. The invention relates to the technical field of petroleum drilling tools. According to the petroleum machinery mounting drilling tool and the mounting method thereof, the output end of a hydraulicrod moves downwards to push a push rod to press downwards, and then T-shaped clamping heads are pressed to overturn, so that a drill bit and the drill rod are fixed, and the drill bit is convenient to mount and dismount; the output end of the hydraulic rod moves downwards to drive the pressing block to move downwards, so that clamping blocks are connected to clamping grooves in a clamped mode, then the drilling machine head and the drill rod are fixed, the drill rod mounting convenience is improved, and the equipment mounting process is improved; and the stability of a fixing structure between the drill rod and the drill bit is controlled through the hydraulic rod, so that the use safety performance of drilling tool equipment is improved, and the problems that in the using process of partof existing petroleum drilling tools, a drill bit and a drill rod are complex to mount and dismount, and the stability of a locking structure is poor are solved.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling tools, in particular to a petroleum machinery installation drilling tool and an installation method thereof. Background technique [0002] Petroleum is a fluid mineral buried deep in the bottom. In the national economy, petroleum is a very important energy source. Compared with coal, it has the advantages of high energy density, convenient transportation and storage, and low pollution. Therefore, many countries have listed petroleum as a strategic Materials; [0003] The existing patent (notification number: CN109184585A) discloses a drill pipe device for petroleum geological exploration, including a first drill pipe, a second drill pipe, a connecting mechanism, a screw head, a drill bit, a limit mechanism and a control mechanism. In the process of realizing the solution, the inventor found that the following problems in the prior art have not been solved: 1. The device is connected wi...
