Publication number: 20230264370Abstract: The present disclosure is directed to systems and methods for simultaneously and concentrically handling cylindrical objects of different diameters. Also, the present disclosure is directed to a handler having a clamp that includes pairs of outer and inner tongs spaced apart on separate sides of the central plane that is orthogonal to a central longitudinal axis of the cylindrical object. Some embodiments may include a clamp having a mounting plate and a piston assembly coupled to the mounting plate where the central plane is parallel to the mounting plate. Some embodiments include a plurality of linkage bars pivotally coupled between the piston assembly and the plurality of outer tongs and inner tongs. In some embodiments, in response to a movement of the piston assembly, the inner and outer tongs pivot between an open position and a closed position to secure the cylindrical object between the inner and outer tongs.Type: ApplicationFiled: February 20, 2023Publication date: August 24, 2023Applicant: TEI Rock Drills, Inc.Inventors: William N.

Patent number: 10919736Abstract: A rod and casing handler according to embodiments of the present disclosure includes a boom mount that is configured to be coupled to a boom. A clamp mounting structure is coupled to the boom mount and has a central portion, a first arm, and a second arm, where each arm extends from the central portion. A first clamp is coupled to the first arm and includes a first set of actuatable tongs and a first removable saddle plate. A second clamp is coupled to the second arm, and it includes a second set of actuatable tongs and a second removable saddle plate. The first removable saddle plate has a first arcuate surface sized and shaped to correspond to a cylindrical body having a first diameter, and the second saddle plate has a second arcuate surface sized and shaped to correspond to a cylindrical body having a second diameter, the first and second arcuate surfaces are disposed to hold the first cylindrical body in coaxial alignment with the second cylindrical body.Type: GrantFiled: November 6, 2018Date of Patent: February 16, 2021Assignee: TEI Rock Drills, Inc.Inventor: William N.

Patent number: 10370900Abstract: This disclosure describes methods and systems for remote control of stroke length and frequency of percussion apparatus, such as a rock hammer drill. At a high level, the hammer drill is allowed to stay at a default low stroke length and high frequency to avoid applying excessive cyclic stress to the housing of the hammer drill and can be controlled to operate at a long stroke length and low frequency when the hammer drill has engaged the target material. The long stroke length and low frequency during operation can be initiated when a sufficient forward feed pressure is provided. While the hammer drill is idling or retracting, the forward fee pressure is not sufficient for the long stroke length operation and thus the drill operates at the default state and at a safe stress level to avoid premature damage.Type: GrantFiled: July 29, 2016Date of Patent: August 6, 2019Assignee: TEI ROCK DRILLS, INC.Inventor: William N.
