Problems solved by technology
[0002] Existing drilling rigs require multiple people to operate and work together. In particular, the loading and unloading of drill pipes is mostly done manually, which requires a large amount of manual work, high labor intensity, low efficiency, and certain potential safety hazards.
[0003] Although in the prior art there is a side orientation manipulator (or other drill pipe conveying device) to pick up the drill pipe, but when the automatic drilling rig installs the drill pipe, it is necessary to connect the threads at both ends of the drill pipe. This process requires the power head to rotate and adjust the speed, and the power head Rotation and propulsion are coordinated at the same time, and the efficiency of this fastening (threading) process is not high

The invention belongs to the field of mechanical design, and relates to a device and a method for automatically attaching a rod of a drilling rig, comprising a frame, a power head and a gripper arranged on the frame, and a manipulator for auxiliary attachment of a drill rod. It is used to fix the drill pipe; the power head includes a water braid arranged in the power head, and the water braid is matched and connected with the attached drill pipe; the manipulator grabs the attached drill pipe and fixed it with the water braid, and the power head drives the fixed water The braided and connected drill rods move toward the drill rod in the holder and complete the drill rod movement. The invention realizes the conversion of semi-automatic drilling and automatic drilling, greatly improves the efficiency of adding and connecting the drill pipe, avoids manual screwing of the drill pipe, and reduces labor intensity.
Description
technical field [0001] The invention belongs to the field of mechanical design, and relates to an automatic rod-up device and method for a drilling rig. Background technique [0002] Existing drilling rigs require multiple people to operate and work collaboratively. In particular, the loading and unloading of drill pipes is mostly carried out manually, which requires a large amount of manual work, high labor intensity, low efficiency, and certain safety hazards. [0003] Although the prior art has the use of side azimuth manipulators (or other drill pipe conveying devices) to pick up the drill pipe, when the automatic drilling machine installs the drill pipe, it is necessary to connect the threads at both ends of the drill pipe. This process requires the power head to rotate and adjust the speed, and the power head Rotating and advancing are matched at the same time, and the efficiency of this connection (thread connection) process is not high.
