Abstract

A system and method for transferring pipe according to which a pipe joint is positioned in a pipe lift in a first position and moved to a second position before being transferred from the pipe lift to a pipe shuttle and moved to a third position.

Claims

1. A pipe transfer system comprising:

a rack for storing at least one pipe in a substantially horizontal position;

a lift pivotal between a horizontal position in which it receives a pipe from the rack, and a vertical position in which it supports the pipe in a vertical position; and

a shuttle for receiving the pipe in its substantially vertical position and moving it to another substantially vertical position spaced from the first-mentioned substantially vertical position.

2. The system of claim 1 further comprising a grip associated with the lift for gripping the pipe during the movement of the lift.

3. The system of claim 1 further comprising a feeder for feeding the pipe from the rack to the lift.

4. The system of claim 3 wherein the feeder comprises a rotatable shaft, and at least one starwheel mounted on the shaft for rotation therewith and adapted to receive the pipe from the rack and transfer it to the lift.

5. The system of claim 1 further comprising a grip associated with the shuttle for gripping the pipe during the movement of the shuttle.

6. The system of claim 1 further comprising at, least one arm associated with the shuttle for gripping the pipe and moving the pipe from the other substantially vertical position to a position spaced angularly from the other substantially vertical position.

7. The system of claim 1 wherein the pipe is adapted to be attached to a pipe string, and wherein the other substantially vertical position is above the upper end of the pipe string.
