Abstract

The invention discloses a drill rod assembling and disassembling mechanical arm of a myriameter well drill, which is composed of a base, four sections of connecting rods connected in hinged mode, a suspension girder, two mechanical catching hands, a pipe holder mechanism, three groups of hydraulic cylinders. The three groups of hydraulic cylinders are respectively hinged between the base and the connecting rods and between the connecting rods. The suspension girder is fixed between two connecting rods of a fourth section, the two mechanical catching hands are arranged at the bottom of the suspension girder and arranged in a front and back mode, and the pipe holder mechanism is arranged on the outer side of the front end of the suspension girder. The pipe holder mechanism is composed of a fixed cantilever, a hydraulic cylinder, a vertical arm, a movable arm and a supporting wheel. After the hydraulic cylinder of the pipe holder mechanism is contracted, the supporting wheel is driven to overturn outwards to the outer side; and after the hydraulic cylinder extends, the supporting wheel is driven to overturn inwards to the position below the suspension girder and can be supported on the bottom surface of a drill rod. The drill rod assembling and disassembling mechanical arm not only enables the drill rod to be conveyed to a well platform in a perpendicular-to-the-ground mode, but also enables the drill rod to be conveyed to the well platform in an inclined mode, and can carry out reverse-direction operation and dismantle the drill rod.
