Method and apparatus for handling pipe

Abstract

An apparatus and method for handling pipe includes an elongate frame structure for mounting on a ground surface, in which a carriage unit is mounted on the frame structure and is operable for selective and reciprocal shifting along the frame structure. A boom member mounted on the carriage unit is operable for selected pivotal movement relative to the carriage unit, and a plane generally parallel to the boom member's longitudinal axis, about a generally horizontal pivot axis oriented transverse to the direction of shifting of the carriage unit along the frame structure. An elongate pipe carrier mounted on the boom member as dimensioned for receiving pipe so that the pipe's longitudinal axis is substantially parallel to the longitudinal axis of the boom member and the pipe member, wherein the pipe carrier is operable for selective pivotal movement about its longitudinal axis.

1 . Apparatus for handling pipe comprising:
 an elongate frame structure for mounting on a ground surface;   a carriage unit mounted on the frame structure selectively operable for reciprocal shifting along the frame structure;   a boom member mounted on the carriage unit operable for selective pivotal movement relative to the carriage unit, in a plane generally parallel to the boom member's longitudinal axis, about a generally horizontal pivot axis oriented transverse to the direction of shifting of the carriage unit along the frame structure; and   an elongate pipe carrier mounted on the boom member dimensioned for receiving pipe so that the pipe's longitudinal axis is substantially parallel to the longitudinal axes of the boom member and the pipe carrier, wherein the pipe carrier is operable for selective pivotal movement about its longitudinal axis.   
   
   
       2 . The apparatus of  claim 1  further including a first actuator mechanism mounted on the carriage unit selectively operable for pivoting the pivot assembly and the boom member about the pivot axis. 
   
   
       3 . The apparatus of  claim 2  further including a second actuator mechanism mounted on the boom member selectively operable for pivoting the pipe carrier about its longitudinal axis relative to the boom member. 
   
   
       4 . The apparatus of  claim 3  wherein spaced-apart arms are mounted on the pipe carrier extending at an angle outwardly from one side thereof for receiving pipe from a pipe rack or the like. 
   
   
       5 . The apparatus of  claim 4  wherein the spaced-apart arms are provided with retainers for engaging pipe as it initially is removed from a pipe rack. 
   
   
       6 . Apparatus for transferring pipe from a first station and presenting it to an elevated second station, comprising:
 an elongate frame structure for mounting on a ground surface;   a carriage unit mounted on the frame structure selectively operable for reciprocal shifting along the frame structure;   a boom member mounted on the carriage unit operable for selective pivotal movement relative to the carriage unit, in a plane generally parallel to the boom member's longitudinal axis, about a pivot axis generally oriented horizontally and transverse to the direction of shifting of the carriage unit along the frame structure; and an elongate pipe carrier mounted on the boom member dimensioned for receiving pipe so that the pipe's longitudinal axis is substantially parallel to the longitudinal axes of the boom member and the pipe carrier;   arm members rigidly mounted on and extending laterally from opposite sides of the pipe carrier;   a first actuator mechanism mounted on the carriage unit selectively operable for pivoting the boom member and the pipe carrier about the pivot axis from a substantially horizontal position to a selected inclined position;   a second actuator mechanism mounted on the boom member selectively operable for pivoting the pipe carrier about its longitudinal axis relative to the boom member in a first direction so that pipe from a first station may engage the arm members on one side of the pipe carrier, the second actuator mechanism operable for pivoting the pipe carrier in a second direction to permit pipe to roll onto the pipe carrier; and   power-driven means mounted on the frame structure selectively operable for advancing the carriage unit from the first station to a position adjacent the second station, wherein the first actuator mechanism can be operated to pivot the boom member to incline it upwardly, thereby presenting a forward end of the pipe to the second station, and for retracting the carriage unit from a position adjacent the second station to a position adjacent the first station.
