COILED TUBING UNIT LOCKING KNEE-JOINT MECHANISMS |
| 摘要 |
A knee-joint mechanism for a folding gooseneck used in a coiled tubing unit, includes a main structure having a distal end pivotally attached thereto, the knee-joint mechanism including an articulated member attached between the main structure and the pivotally attached distal end of the gooseneck, the articulated member having a joint, and a cylinder attached between the main structure and the articulated member. The arm of the cylinder is extended to push the joint of the articulated member to an over-center position, thereby locking the articulated member. |
