Abstract
Abstract A positive indexing mechanism for positioning a movable drill rod storage rack on a mobile rock drill unit. The storage rack includes spaced apart rack members having a plurality of receptacles for storing elongated drill rod sections laterally seriatim with respect to the axis of the drill string. The indexing mechanism includes movable plungers associated with the individual receptacles on one of the rack members and operable to be actuated by the drill rod sections when placed in the receptacles. The plungers are responsive to the absence of a drill rod section from a receptacle to engage a sliding catch mechanism for arresting the movement of the storage rack in a predetermined position for loading or unloading a drill rod section. A hydraulic control circuit associated with the storage rack and the indexing mechanism includes a selector valve and actuator device for providing positive alignment of the rack for removing a rod section therefrom or alternatively loading a rod section, which has been disconnected from the drill string, into an empty receptacle.

Claim 3
Dependent Claim
141 words
In combination with a rock drill unit including an elongated support, drill motor means movably mounted on said support for driving a drill string made up of elongated drill rod sections coupled end to end, and drill rod storage means movably mounted on said support and operable to store a plurality of drill rod sections laterally seriatim with respect to the longitudinal axis of said drill string, said drill rod storage means including drill rod receiving means operable to receive and hold said drill rod sections, the improvement comprising: indexing means operable to provide for positioning said drill rod storage means in a predetermined position with respect to said longitudinal axis of said drill string whereby said receiving means is in alignment with said longitudinal axis of said drill string for receiving a drill rod section decoupled from said drill string.
Claim 4
Dependent Claim
141 words
In combination with a rock drill unit including an elongated support, drill motor means movably mounted on said support for driving a drill string made up of elongated drill rod sections coupled end to end, and drill rod storage means movably mounted on said support and operable to store a plurality of drill rod sections laterally seriatim with respect to the longitudinal axis of said drill string, said drill rod storage means including drill rod receiving means operable to receive and hold said drill rod sections, the improvement comprising: indexing means operable to provide for positioning said drill rod storage means in a predetermined position with respect to said longitudinal axis of said drill string whereby said receiving means is in alignment with said longitudinal axis of said drill string for receiving a drill rod section decoupled from said drill string.
Claim 5
Dependent Claim
121 words
In combination with a rock drill unit including an elongated support, drill motor means movably mounted on said support for driving a drill string made up of elongated drill rod sections coupled end to end, and drill rod storage means including drill rod receiving means movably mounted on said support and operable to store a plurality of drill rod sections laterally seriatim with respect to the longitudinal axis of said drill string, the improvement comprising: indexing means including means responsive to said drill rod sections being received in said receiving means to provide for positioning said drill rod storage means in a predetermined position with respect to said longitudinal axis in response to the movement of said drill rod storage means.
Claim 6
Dependent Claim
121 words
In combination with a rock drill unit including an elongated support, drill motor means movably mounted on said support for driving a drill string made up of elongated drill rod sections coupled end to end, and drill rod storage means including drill rod receiving means movably mounted on said support and operable to store a plurality of drill rod sections laterally seriatim with respect to the longitudinal axis of said drill string, the improvement comprising: indexing means including means responsive to said drill rod sections being received in said receiving means to provide for positioning said drill rod storage means in a predetermined position with respect to said longitudinal axis in response to the movement of said drill rod storage means.
Claim 7
Dependent Claim
45 words
The invention set forth in claim 4 wherein: said drill rod storage means comprises spaced apart storage rack members movably mounted on said support and said receiving means for receiving said plurality of drill rod sections is mounted on one of said storage rack members.
Claim 8
Dependent Claim
105 words
The invention set forth in claim 4 wherein: said receiving means comprises a plurality of spaced receptacles each of said receptacles being operable to receive and support an end portion of a drill rod section whereby said drill rod sections are stored adjacent one another and laterally seriatim with respect to the longitudinal axis of said drill string, and said indexing means includes means responsive to said drill rod sections being received in said receptacles to provide for positioning said drill rod storage means in a predetermined position with respect to said longitudinal axis in response to the movement of said drill rod storage means.
Claim 9
Dependent Claim
81 words
The invention set forth in claim 5 wherein: said indexing means comprises catch means movably mounted on said one storage rack member, and said indexing means includes movable projection means operable to be actuated by said drill rod sections received in said receptacles, said movable projection means being engageable with said catch means in response to the movement of said one storage rack member for positioning said drill rod storage means in a predetermined position with respect to said longitudinal axis.
Claim 10
Dependent Claim
55 words
The invention set forth in claim 6 wherein: said movable projection means includes actuating means engageable with said drill rod sections when said drill rod sections are received in said receptacles for actuating said movable projection means to be engaged by said catch means in response to the movement of said drill rod storage means.
Claim 11
Dependent Claim
89 words
The invention set forth in claim 7 wherein: said catch means includes a stop operable to engage projection means mounted on said support whereBy in response to the movement of said drill rod storage means to position a receptacle for unloading or receiving a drill rod section said catch means is operable to be arrested by said stationary projection means and in turn said catch means is operable to engage said movable projection means to position a receptacle on said one rack member in alignment with said longitudinal axis.
