Spring-loaded rod handling device

Abstract

A rod handling device includes a pivot rod, first clamp assembly pivotingly coupled to the pivot rod, a second clamp assembly pivotingly coupled to the pivot rod, and at least one locking assembly configured to move between a locked position and an unlocked position. While in the locked position the locking assembly prevents rotation between the first clamp assembly and the second clamp assembly.The rod handling device also includes a biasing member coupled to the pivot rod, the biasing member being configured to urge the locking assembly toward the locked position.

Description

technical field [0001] The present invention relates to a device for manipulating elongated members, and in particular to rod manipulating devices. Background technique [0002] Drill rods are often manually manipulated in transferring drill rods, such as kelly, core barrels, etc., from the rod racks into position on the feed frame of a conventional drilling machine. When seated on the feed frame, the drill rod is coupled to the drill string. The drill pipe is also often manually manipulated as it is removed from the drill string. Due to the size of the drill rod, it may be difficult to manually manipulate the drill rod. For example, the drill rod is often sufficiently long and of a diameter that it is difficult to grasp and manipulate the drill rod with only hands. [0003] A number of devices have been provided for locking to the drill pipe which include a gripping device which engages the drill pipe and an operating handle which provides an easier grip for the operator...

AI Technical Summary

Problems solved by technology

Although these devices allow engagement of the drill pipe, these devices can accidentally disengage, causing the operator to drop the drill pipe
