Abstract
A system includes a utility chassis for use with rock drills for automatic and safe drilling of target surfaces. The utility chassis has a lightweight vertical frame member with an overall center of gravity that allows for manual lift handles to be arrayed about the center of gravity for easy loading and unloading onto transportation vehicles without the need for separate heavy machinery. The utility chassis incorporates a spring-centered closed position valve for drill rotation and a three-way spring-centered retract with two open feed positions valve for increased safety. A hinged drill rod guide cap is incorporated into the drill rod guide for quick removal of the chassis from lodged or broken drill rods. The chassis is lighter, more ergonomic, and safer than prior art chasses.
Claims19
A rock drip system comprising:
- a vertical frame member having a drill side and an operator side;
- a drill assembly comprising:
- 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, and
- a rock drill that is attached to the drill guide sleeve:
- a control tree extending from the operator side of the vertical frame member, the control tree having one or more operator handle grips;
- and
- an anti-vibration assembly that interconnects the control tree and the vertical frame member, the anti-vibration assembly being adapted to reduce the amount of vibration transmitted from the vertical frame member to the control tree and/or the one or more operator handle grips.
The rock drill system of claim 6 wherein the elastomeric material is selected from the group consisting of rubber, thermosets, and thermoplastics, or any combination thereof.
