Embodiment Construction
[0026] Further describe below in conjunction with embodiment.
[0027] The lead wire of sensor 11 is passed in the axle seat 8 pipes via holding clamp mechanism 3, outer arm 4, rotating arm 5. The hydraulic oil pipe passes in the shaft seat 8 pipes through the outer arm 4 and the rotating arm 5 . Not shown in the figure.
[0028] Outer arm 4 stretches, retracts length, and there are travel switch control, numerical control control, hand press switch control several. A rotary hydraulic oil cylinder is installed in the shaft seat 8, which is used to drive and control the pivoting arm shaft 6 to drive and control the pivoting arm 5 to rotate left and right. The rotating arm shaft 6 is tubular and hollow. A hydraulic cylinder for lifting is also installed in the shaft seat 8. Not shown in the figure. Rotary arm 5 can be controlled lifting by the hydraulic cylinder of lifting. The angle of rotation of the clamp mechanism 3 and the angle of rotation of the rotating arm 5 also ...

The invention relates to a device for replacing manual operation of an existing well drilling wellbay with automation, equipment construction on the original well bay has no need to be changed, and only a rotary arm device is additionally arranged. The rotary arm device is formed by a rotary arm, an outer arm, a holding clamp mechanism, a rotary arm shaft, a shaft seat, a hydraulic control mechanism and an electric appliance control circuit system. The shaft seat is arranged on a side of the wellbay. The outer arm can be stretched in the rotary arm. The holding clamp mechanism is arranged on a front end of the outer arm, and can be rotated to change the direction. Clamping jaws can be opened and closed. The clamping jaws are opened to be rotated along with the rotary arm so as to 'sweep' a drill rod hung on the side of the wellbay, after the drill rod is captured, the rotary arm is rotated reversely, and the holding clamp mechanism is rotated to change the direction. The drill rod is moved right above a wellhead and is automatically aligned to fall into a wellhead joint or a mouse hole. The drill rod can be moved to a specified position from the wellhead in a drill rod taking process, and a rod pushing mechanism is arranged, so that the drill rods can be very conveniently and quickly arranged in order. The device has low cost, and is fast to modify and install, the labor intensity of workers can be reduced, and the efficiency is improved.
Description
technical field [0001] The invention relates to oil and natural gas drilling equipment, in particular to an automatic device for drilling. Background technique [0002] In the existing oil and gas drilling, the operation on the well platform is mainly manual. The workers pull the drill pipe suspended by the wire rope back and forth from the edge of the well platform to the wellhead. The alignment of the drill pipe and the wellhead, the advancement and retreat of the tongs, Heavy physical labor such as pushing and pulling away, on the one hand, consumes a lot of physical strength of the workers, and on the other hand, the work efficiency is too slow. There are a few automatic drilling in foreign countries, but the drilling equipment is expensive, and the main reason is that the structure of the equipment on the well platform is very different from that of the existing drilling well platform. That is to say, under the condition of not changing the original drilling rig equipm...
