ABSTRACT:
Method and system for connecting a joint of pipe to a top drive motor just above the drilling platform of a drilling rig where the connection can be made quickly and safely by a drilling operator. The system includes a top drive motor that tilts about a horizontal axis and a pipe launcher that brings joints of pipe up to the drilling platform for connection with a top drive motor at a safe and convenient height above the platform. The top drive motor further includes a clamping assembly that grasps and pulls the joint of pipe to the motor as the connection is being made. The clamp assembly supports the motor-pipe connection as the top-drive motor is raised in the drilling mast of the rig bringing the joint of pipe up into a vertical orientation for connection with the drill tubing string.
