发明名称 PIVOTING GOOSENECK
摘要 <p>A gooseneck (30) for coiled tubing operations have a folding design to allow for a more compact design for storage and transport. The gooseneck may remain attached to the injector (42) during transport, thereby decreasing the equipment required to move and set-up the coiled tubing equipment. The gooseneck includes a linkage mechanism for connecting a pair of support struts (44, 45) between the injector body (42) and the tubing guide (36). The linkage allows the guide to follow a substantially parabolic path as it tracks the tubing from the reel to the injector.</p>
