Problems solved by technology

When the drill floor robot connects a single drill pipe, because the hydraulic elevator of the pipe arrangement robot can only control one end of the drill pipe, and the other end is in a free state, it is easy to shake in the air and difficult to control. In the past, only pre-made Ramp and manual righting, labor-intensive, low efficiency, potential safety hazards, affecting drilling speed

Embodiment Construction

[0011] The Pipe Handling Robot is a robust integrated robot that guides drill pipe joints into ratholes. The pipe handling arm is bolted to the front end of the catwalk trolley and can handle pipe sizes from 2 7 / 8” to 36” without changing any parts.

[0012] When the pipe processing mechanical arm is working, the dumping cylinder (1) pushes the inner arm (3), and drives the outer arm (4) and its connected parts to rotate around the connecting pin on the top of the pillar (2) to the maximum angle and then Swivel, while rotating, the idler hydraulic cylinder (7) pushes the idler roller (6) to flip 90° inwardly in the direction perpendicular to the outer arm. When the drill pipe is pressed against the idler roller (6), the swing hydraulic cylinder (8) drives the rocker The arm (9) rotates 180° upwards, and at the same time, the rocker arm pressure roller (10) presses the drill pipe, and then the whole moves with the lifting of the drill pipe until the drill pipe is vertical, the ...

Abstract

The invention discloses a pipe processing mechanical arm. The mechanical arm is installed on a catwalk machine of a drilling module of an oil drilling platform. The device is composed of a dumping hydraulic cylinder (1), a supporting column (2), an inner arm (3), an outer arm (4), a telescopic hydraulic cylinder (5), a carrier roller (6), a carrier roller hydraulic cylinder (7), a swing hydrauliccylinder (8), a rocker arm (9), a rocker arm pressing roller (10) and the like which are connected mainly through lug plates, pins, sliding blocks and the like. All the components can independently act and are powered by hydraulic cylinders, motors and springs. All the components are tightly matched according to the sequence to jointly complete the task.

Description

technical field [0001] The invention relates to a mechanical arm, in particular to a pipe handling mechanical arm. The pipe handling mechanical arm is installed on the catwalk machine of the drilling module of the oil drilling platform. When the catwalk machine transports the drill pipe, the mechanical arm straightens and stabilizes the drill pipe, and cooperates with the pipe arrangement robot to put the drill pipe into the mouse hole. Background technique [0002] During the drilling construction process, it is necessary to continue to connect drill pipes, and the drill pipes need to be connected to a stand (three single drill pipes form a stand), and the stand needs to be completed in a rat hole. When the drill floor robot connects a single drill pipe, because the hydraulic elevator of the pipe arrangement robot can only control one end of the drill pipe, and the other end is in a free state, it is easy to shake in the air and difficult to control. In the past, only pre-m...
