Abstract: The drill rod (10) includes a first rod section (14) and a second rod section (16) that are welded together along their mating ends (14b and 16b respectively). The mating ends are heat treated to reduce the elevated hardness that is caused by the welding. Both, the first rod section and the second rod section, each include an interior passage (15 and 17 respectively) that extends between the free end (14a and 16a respectively) to the mating end. A hardened externally threaded portion (18) on the first rod section can be threaded into the separately hardened internally threaded portion in the interior passage of a second rod section of another drill rod. The first drill rod is threaded into the other drill rod so that the surface of an annular face on the free end of the first drill rod abuts against a mating shoulder of the second drill rod.

Abstract translation: 钻杆（10）包括沿其配合端（分别为14b和16b）焊接在一起的第一杆段（14）和第二杆段（16）。 配合端部进行热处理，以降低由焊接引起的高硬度。 第一杆部分和第二杆部分都分别包括在自由端（14a和16a）分别延伸到配合端的内部通道（15和17）。 第一杆部分上的硬化的外螺纹部分（18）可以被拧入在另一个钻杆的第二杆部分的内部通道中的单独硬化的内螺纹部分中。 第一钻杆被拧入另一个钻杆中，使得第一钻杆的自由端上的环形表面的表面抵靠第二钻杆的配合肩部。

Abstract: A removable guide member for guiding drill string components in a drill hole includes an elongated body having a centerline axis with a bore extending along the axis. The body terminates in a head end having a preselected radial dimension with respect to the centerline axis. The guide member is adapted to be threadably connected to adjoining drill string components. The head end radial dimension is preselected to space an outer surface thereof in close proximity to a drill hole sidewall, so that if the drill string begins to deviate out of alignment, the outer surface of the head end will contact the drill hole sidewall to stabilize alignment. The guide member can be inserted into any position along the drill string.

Abstract: A drill rod changer assembly for a drill rig includes an elongated support shaft having a housing at each end for retaining ends of drill rods, the support shaft being adapted for removable attachment to a drill rig structure, a carousel-type drill rod spacer on the shaft and a pair of gripper arms adapted for removable attachment to a drill rig structure at spaced apart positions adjacent each end of the support shaft. A hydraulic actuation device rotates the support shaft and carousel drill rod spacer between a rod storage position and a rod usage position. Each gripper arm is moved between the drill rod storage and usage positions by hydraulic actuation devices on each arm. Each gripper arm carries a sliding gate member that opens and closes the housings in response to movement of the gripper arm. The support shaft, and each gripper arm assembly being supplied as modularized assemblies that can be individually attached and removed from a drill rig to expeditiously change between various lengths of drill rod.

Abstract: A drill rod changer assembly for a drill rig includes an elongated support shaft (5) having a housing (20, 30) at each end for retaining ends of drill rods, the support shaft being adapted for removable attachment to a drill rig structure (3), a carousel-type drill rod spacer (120) on the shaft and a pair of gripper arms (70, 74) adapted for removable attachment to a drill rig structure at spaced apart positions adjacent each end of the support shaft. A hydraulic actuation device (40) rotates the support shaft and carousel drill rod spacer between a rod storage position and a rod usage position. Each gripper arm is moved between the drill rod storage and usage positions by hydraulic actuation devices on each arm. Each gripper arm carries a sliding gate member that opens and closes the housings in response to movement of the gripper arm. The support shaft, and each gripper arm assembly being supplied as modularized assemblies that can be individually attached and removed from a drill rig to expeditiously change between various lengths of drill rod.

Abstract: A drilling apparatus, having a drilling tower, tiltable for angle drilling, on a drilling platform with an aperture for a drill string, includes a dust seal holder that extends into the aperture in the platform, the dust seal holder being connected to the tower, so as to move up and down in the aperture in an arcuate path along with the drilling tower, as the tower is tilted for angle drilling, the dust seal holder being disconnected from the tower, so as to be not movable, as the tower is moved between a horizontal and vertical position.
