Patent Application

This patent disclosure relates generally to drilling systems and, more particularly, to a control assembly for a drilling system, and methods for operating the same.
Drilling systems with multiple component drilling assemblies are known. Known drilling systems include a control assembly wherein an input received through a control mechanism, for example moving or actuating a joystick in a lateral direction, moves a first component of the drilling assembly, and the same input, moving the joystick in the lateral direction, moves a second component of the drilling assembly when an auxiliary input, for example a button is pushed, on the control mechanism.
As a result, simultaneous movement of both the first component and the second component is not possible using conventional approaches. A drilling system including a control assembly operably connected to a drilling assembly such that simultaneous movement of multiple components of the drilling assembly is enabled could reduce the amount of time required to move the drilling assembly to a desired position which may result in more efficient use of the drilling system.
It will be appreciated that this background description has been created to aid the reader, and is not to be taken as an indication that any of the indicated problems were themselves known in the art.

According to one aspect of the disclosure, the control assembly 200 is configured such that the first control mechanism 220 is devoid of a direction that the first control mechanism 220 may be actuated in to move, for example pivot or translate, the feed body 144 relative to the boom 120. According to one aspect of the disclosure, the control assembly 200 is configured such that the second control mechanism 240 is devoid of a direction that the second control mechanism 240 may be actuated in to move, for example pivot or translate, the boom body 128 relative to the base 16.
According to one aspect of the disclosure, a method for operating the machine 10 includes the steps of: actuating the first control mechanism 220 of the control assembly 200 in a first direction D1, thereby pivoting the boom body 128 about the first boom pivot axis 130, actuating the first control mechanism 220 in a second direction D2, thereby pivoting the boom body 128 about the second boom pivot axis 132, actuating the second control mechanism 240 of the control assembly 200 in the fourth direction D4, thereby pivoting the feed body 144 relative to the boom body 128 about the first feed pivot axis 148, actuating the second control mechanism 240 in the fifth direction D5, thereby pivoting the feed body 144 relative to the boom body 128 about the second feed pivot axis 150, wherein at least one of the actuating the first control mechanism 220 steps is performed simultaneously with at least one of the actuating the second control mechanism 240 steps.
According to one aspect of the disclosure, the method may further include the step of actuating the first control mechanism 220 in the third direction D3, thereby translating the boom body 128 along the boom longitudinal axis 126. The step of actuating the first control mechanism 220 in the third direction D3 may be performed separate from each of the other steps of the method, or may be performed simultaneously with at least one of the other steps of the method.
According to one aspect of the disclosure, the method may further include the step of actuating the second control mechanism 240 in the sixth direction D6, thereby pivoting the feed body 144 relative to the boom body 128 along the third feed pivot axis 152. The step of actuating the second control mechanism 240 in the sixth direction D6 may be performed separate from each of the other steps of the method, or may be performed simultaneously with at least one of the other steps of the method.
According to one aspect of the disclosure, the method may further include the step of actuating the second control mechanism 240 in the seventh direction D7, thereby translating the feed body 144 relative to the boom body 128 along the feed longitudinal axis 142. The step of actuating the second control mechanism 240 in the seventh direction D7 may be performed separate from each of the other steps of the method, or may be performed simultaneously with at least one of the other steps of the method.
The machine 10 may be configured for use at a drilling site and to be operated by an operator to drill one or more holes in a surface, such as a rock wall. The assembly distal end 104 of the drilling assembly 100 may be defined by the drill bit 166 which is configured to drill one or more holes in the surface. Through inputs into the control assembly 200 the drilling assembly 100, specifically the drill bit 166 can be moved from an initial position to a drilling position. Previous machines are not configured to allow the simultaneous movement in multiple directions, or multiple degrees of freedom. For example, an operator of a previous machine moving a drill bit from an initial position to a drilling position would require moving a first portion of the machine, and then as a separate step, moving a second portion of the machine. The machine 10 is configured such that the both the boom body 128 and the feed body 144 are movable simultaneously through simultaneous inputs into both the first control mechanism 220 and the second control mechanism 240.
According to one aspect of the disclosure, the drilling assembly 100 is configured such that the drifter 160, including the drill bit 166, is carried by the feed 140 such that movement of the feed body 144 also moves the drill bit 166. For example when the feed body 144 pivots about the first feed pivot axis 148, the drill bit 166 also pivots about the first feed pivot axis 148. The drilling assembly may further be configured such that the feed 140 is carried by the boom 120 such that movement of the boom body 128 also moves both the feed body 144 and the drill bit 166. For example, when the boom body 128 pivots about the first boom pivot axis 130, the drill bit 166 also pivots about the first boom pivot axis 130.
Thus, to move the drill bit 166 from the initial position to the drilling position, an operator may actuate the first control mechanism 220, for example in the first direction D1 thereby pivoting the boom body 128 about the first boom pivot axis 130, and may simultaneously actuate the second control mechanism 240, for example in the fourth direction D4 thereby pivoting the feed body 144 about the first feed pivot axis 148. This simultaneous actuating of the first control mechanism 220 and the second control mechanism 240 results in the drill bit 166 simultaneously pivoting about the first boom pivot axis 130 and the first feed pivot axis 148.
The simultaneous movement of the drill bit 166 described above may lead to faster movement of the drill bit 166 from the initial position to the drilling position than first moving a first portion of a drilling assembly, and then after moving the first portion, separately moving a second portion of the drilling assembly.
According to one aspect of the disclosure, the machine 10 may include an electrohydraulic system that includes electric signals sent by, for example, the controller 20, and the electric signals drive electrohydraulic valves, the output of which is directed to components of the drilling assembly 100, for example one or more of the plurality of actuators 182 or the motor 168.
