Embodiment Construction

[0034] A drill rod handling device is provided which may be incorporated into a drilling rig either as an accessory or as an integral part of the drilling rig. Such rigs typically include an upright mast extending upward from a slide table. The mast may include a drive nose movable along the mast between a lowered position adjacent the slide table and a raised position towards the free end of the mast. The mast is pivotable at its mounting point about a transverse axis lying substantially in the plane of the slide table. The pivotal movement of the mast is controlled and enables the mast to assume a variety of upright positions, which may include horizontal or vertical positions, to enable the borehole to be drilled at any desired angle.

[0035] In at least one embodiment, the drilling rig is mountable to a vehicle (not shown). In other embodiments, the drill rig may be transported by vehicle and then remain in a fixed position when unloaded from the vehicle. In yet other ...

Abstract

According to one embodiment of the invention, the drill rod handling device includes a movable clamp. A position sensor system for the drill rod handling apparatus includes a level sensor configured to detect a position of the movable jaw relative to gravity. The position sensor system also includes a rotation sensor configured to detect a rotational position of the movable jaw relative to a defined axis parallel to gravity. Additionally, the position sensor system includes a control center communicatively connected to the level sensor and the rotation sensor.

Description

technical field [0001] This invention relates to handling devices for elongated parts such as lengths of drill pipe, columns, solid tubes, thin walled tubes, etc. [0002] Throughout this specification, the term "drill pipe" is considered to include all forms of elongated members used in the drilling, installation and maintenance of holes and wells in the ground, including rods, pipes, pipes and shells, and they are connected to each other to be used in holes. Background technique [0003] One particular application of the invention relates to an accessory usable with a drilling machine used in drilling. Such drilling rigs typically comprise an upright mast with a drill head mounted thereon, wherein the drill head is movable along the mast and the drill head is provided with an upper end that receives and engages a drill string and imparts rotation to the drill string The device of force, so that it rotates in the borehole, so that this rotation produces cutting action thr...
