  • Publication number: 20230366276
    Abstract: A pipe rack for a machine includes a drill carousel for supporting at least two drill strings. The drill carousel defines a first end and a second end spaced apart from the first end. The drill carousel includes a base disposed proximate to the first end of the drill carousel and a plurality of receptacles coupled to and extending from the base. At least two of the plurality of receptacles are adapted to at least partially receive a corresponding drill string from the at least two drill strings. The pipe rack also includes a retainer plate. The retainer plate is adapted to couple with the at least two drill strings. The pipe rack further includes at least one breaker plate disposed between the base and the retainer plate. The at least one breaker plate is spaced apart from the retainer plate along a first axis of the machine.

  • Patent number: 11274510
    Abstract: A pipe loading system for a drilling machine includes a stem and a first receptacle adapted to removably receive a first end of a first pipe. The pipe loading system includes a guide ring removably disposed on the first receptacle and adapted to removably receive a first end of a second pipe. The pipe loading system also includes a second receptacle defining a first receiving portion and adapted to removably receive a second end of the first pipe. The pipe loading system further includes a liner assembly removably disposed on the second receptacle and defining a second receiving portion. The second receiving portion is adapted to removably receive a second end of the second pipe. A diameter of the second pipe is smaller than a diameter of the first pipe.

  • Publication number: 20190368285
    Abstract: A locking mechanism for locking a mast includes a double acting cylinder having a piston coupled with a piston rod adapted to slide inside a cylinder barrel. The cylinder barrel is coupled with a first shaft through a first coupling pin. Mounting brackets coupled to a base plate of the mast guide a sliding motion of the first coupling pin, and the cylinder barrel. A first locking pin connected to the piston rod selectively engages a first side plate based on the sliding motion of the piston rod. A retraction stopper restricts a sliding motion of the first locking pin away from the first side plate, and subsequently causes a movement of the cylinder barrel towards the first end of the cylinder barrel. A second locking pin connected to the shaft selectively engages a second side plate based on the sliding motion of the cylinder barrel.
