Hydraulically Powered Trough Extension for a Pipe Handling, Pipe Laydown and Pipe Pickup Machine

摘要

A hydraulically powered trough extension attached to a pipe handling, pipe pickup and pipe laydown tool can be extended hydraulically to facilitate transport of pipe to/from a drill rig. The hydraulically powered trough extension is semipermanently attached to the trough of the pipe handling, pipe pickup and pipe laydown machine to eliminate the need for special equipment to attach a trough extension to the trough. A specially designed hinge enables the hydraulically powered trough extension to be folded so as to lay flat on the trough of the pipe handling, pipe laydown and pipe pickup machine. When the hydraulically powered trough extension is fully extended the hinge mechanism does not obstruct the movement of pipe on or off the pipe pickup and pipe laydown machine. This feature enables the hydraulically powered trough extension to be easily and safely extended for moving pipe to/from the drill platform and when folded for easy transport to another work site without the need for extra equipment.

主权项

1. A hydraulically powered trough extension for a pipe handling, pipe laydown and pipe pickup machine comprising:
a trough extension; a trough attached to a pipe handling, pipe laydown and pipe handling pickup machine; a first hydraulic cylinder attached to said trough extension; a second hydraulic cylinder attached to said trough; a first set of substantially L shaped hinge arms each with a short arm and a long arm with said short arm connected to said trough extension and said long arm connected to said trough; a second set of substantially L shaped hinge arms each with a short arm and a long arm with said short arm connected to said trough extension and said long arm connected to said trough positioned on the opposite side from said first set of substantially L shaped hinge arms of said hydraulically powered trough extension and said trough; a third set of substantially L shaped hinge arms each with a short arm and a long arm with said long arm connected to said trough extension and said short arm connected to said trough; a fourth set of substantially L shaped hinge arms each with a short arm and a long arm with said long arm connected to said trough extension and said short arm connected to said trough and positioned on the opposite side said third set of substantially L shaped hinge arms of said hydraulically powered trough extension and said trough; an extension roller cross shaft connecting said third set and said fourth set of substantially shaped L shaped hinge arms; a trough slide shaft connecting said first set and said second set of substantially L shaped hinge arms; a pivot pin; whereby, the activation of said first hydraulic cylinder attached to said trough extension and activation of said second hydraulic cylinder attached to said trough causes the said first, second, third and fourth substantially L shaped hinge arms attached to said trough extension and said trough to rotate about a plurality of said pivot pins causing said trough extension to fully extend or retract.
