Abstract
A hydraulic drilling machine has a metal chassis shaped as a rectangular parallelepiped, drilling resources located at the front of the chassis, a rotary motor to drive drilling rods, and a hydraulic circuit. An electrical circuit powers the various components of the drilling machine. The machine can be mounted on the arm of a hydraulic mini-digger and operate without an extra hydraulic unit.
Claims26
A hydraulic drilling machine comprising a metal chassis shaped as a rectangular parallelepiped having a first lengthwise extremity arranged to be connected to a hydraulic source, drilling resources located in a bottom part of the metal chassis at a second lengthwise extremity opposite to the first lengthwise extremity, the drilling resources including a rotary motor for driving drilling rods during a drilling operation, the drilling rods, when mounted on the rotary motor during a drilling operation, extending in a direction perpendicular to the longest faces of the metal chassis between the first and second lengthwise extremities, stabilization resources for the position of the drilling machine during a drilling operation mounted on the metal chassis to create a resultant force coaxial to the axis of drilling resources including the rotary motor and the drilling rods when connected to the rotary motor during a drilling operation, and further resources arranged to be mounted on an arm of a hydraulic mini-digger arranged to be connected at the first lengthwise extremity, the further resources being capable of operation without the addition of an extra hydraulic unit, at least two rings being attached, to an upright of the chassis so each ring is attached above another ring, the rings being arranged to receive fixing lugs of a basket for storing the drilling rods.
A hydraulic drilling machine comprising a metal chassis shaped as a rectangular parallelepiped having a first lengthwise extremity arranged to be connected to a hydraulic source, drilling resources located in a bottom part of the metal chassis at a second lengthwise extremity opposite to the first lengthwise extremity, the drilling resources including a rotary motor for driving drilling rods during a drilling operation, the drilling rods, when mounted on the rotary motor during a drilling operation, extending in a direction perpendicular to the longest faces of the metal chassis between the first and second lengthwise extremities, stabilization resources for the position of the drilling machine during a drilling operation mounted on the metal chassis to create a resultant force coaxial to the axis of drilling resources including the rotary motor and the drilling rods when connected to the rotary motor during a drilling operation, and further resources arranged to be mounted on an arm of a hydraulic mini-digger arranged to be connected at the first lengthwise extremity, the further resources being capable of operation without the addition of an extra hydraulic unit, the free extremity of the jacks including a sphere clamped into a cylindrical part having a conduit for greasing the sphere.
A hydraulic drilling machine for enabling an elongated bore to be drilled in a small space, the drilling machine being adapted to be connected to an arm of a hydraulic mini-digger and to receive all its hydraulic power from the mini-digger and having no additional hydraulic power, the drilling machine having a chassis shaped as a right parallelepiped having lengthwise extremities, widthwise extremities and thickness extremities, the lengthwise extremities being spaced from each other by a distance substantially greater than the distance separating the widthwise extremities, and the widthwise extremities being spaced from each other by a distance greater than the distance separating the thickness extremities;
- a turret arranged to be connected to the arm of the hydraulic mini-digger for rotating the chassis about a longitudinal axis that is parallel to a line extending between a first of the lengthwise extremities and a second of the lengthwise extremities, the turret being mounted on the first lengthwise extremity so that when the drilling machine is connected to the arm of the mini-digger the first lengthwise extremity is at the top of the drilling machine;
- a first set of hydraulically activated jacks fixedly mounted on the chassis for stabilizing the position of the drilling machine in the small space, the first set of jacks being arranged to be responsive to the hydraulic activation thereof so that free, stabilizing ends thereof are adapted to move back and forth in a direction that extends between the widthwise extremities, the first set of jacks being proximate the second lengthwise extremity;
- the chassis including a rotary hydraulic motor for driving drill bits for boring the elongated bore, the rotary hydraulic motor being mounted in the chassis for back and forth movement in the direction that extends between the widthwise extremities, the rotary motor being proximate the second lengthwise extremity;
- a second set of hydraulic jacks, the second set of jacks being arranged to be responsive to the hydraulic activation thereof for driving the rotary motor back and forth in the direction that extends between the widthwise extremities, the second set of jacks being fixedly mounted in proximity to the second lengthwise extremity;
- the first and second sets of jacks and the rotary motor being connected to a hydraulic conduit arrangement that is arranged to be powered by a working fluid source of the mini-digger so that the first and second jacks and the rotary motor are arranged to be powered only by the connection to the mini-digger fluid source.
