Abstract
A system includes a utility chassis for use with rock drills for automatic and safe drilling of target surfaces. The system includes a remote control unit that is pneumatically coupled to the system and may be selectively detached from the utility chassis so that the operator may control the system via the remote control unit from afar. The utility chassis has a lightweight vertical frame member with an off-set wheel base that allows the system to maintain its balance and maintain engagement with the ground when while being operated remotely and without being manually supported.
Claims20
A rock drill system comprising:
- a vertical frame member having a drill side and an operator side;
- a drill guide sleeve adapted to move axially along a longitudinal axis of a drill guide shaft that is attached in a parallel orientation to the drill side of the vertical frame member;
- a feed cylinder that is coupled to both the drill side of the vertical frame member and the drill guide sleeve, wherein the feed cylinder drives the drill guide sleeve along the longitudinal axis of the drill guide shaft relative to the vertical frame member;
- a rock drill that is attached to the drill guide sleeve and including a drill rod;
- a foot member supporting the vertical frame member and the drill guide shaft and including a cutout for receiving the drill rod;
- a wheel support member;
- an extension member extending between the wheel support member and the vertical frame member, such that the wheel support member is offset from the vertical frame member via the extension member;
- and
- a wheel and bearing assembly supported on the wheel support member.
