Abstract:
An apparatus for installing a pipe segment in a well pipe comprising:a frame having a reach area formed therein;a first arm pivotally connected to said frame;a first roller rotatably mounted on said first arm;a second arm pivotally connected to said frame;a second roller rotatably mounted on said second arm, said second arm being linked to said first arm so as to cause said second roller to move toward said reach area as said first roller moves into said reach area;a third arm pivotally connected to said frame;a third roller rotatably mounted to said third arm, said third arm being linked to said second arm such that the movement of said second roller toward said reach area causes said third roller to move toward said reach area; andan actuator being linked to at least one of said arms, said actuator adapted to pivot one of said arms such that the respective roller on said arm moves into said reach area, each of said arms being linked together such that each of said arms moves concomitantly with the other arms upon an actuation by said actuator, said rollers being adapted to position the pipe segment within said reach area such that a central longitudinal axis of the pipe segment is located at an identical location within said reach area regardless of a diameter of the pipe segment.
