Abstract
A cutting device support for a mining machine includes a ranging arm, a bracket positioned adjacent an end of the ranging arm, and a thermally-expandable coupling member positioned between the bracket and the ranging arm. The coupling member exerts a force on the bracket and the ranging arm to secure the bracket to the ranging arm.
Claims20
A cutting device support for a mining machine, comprising:
- a ranging arm;
- a bracket positioned adjacent an end of the ranging arm;
- and
- a thermally expandable coupling member positioned between the bracket and the ranging arm, the coupling member, while at a nominal temperature, exerting a force on the bracket and the ranging arm to secure the bracket to the ranging arm.
1 more element
A method for attaching a bracket to an arm comprising:
- aligning an end of the bracket adjacent an end of the arm;
- heating a coupling member to expand a dimension of the coupling member to a first value;
- positioning the coupling member to engage both the bracket and the arm;
- and
- cooling the coupling member until the dimension contracts to a second value less than the first value.
2 more elements
A support for a rock cutting device comprising:
- a bracket including a first groove;
- a support arm including a second groove proximate the first groove;
- and
- a coupling member for connecting the bracket and the support arm, the coupling member including a first end positioned in the first groove and a second end positioned in the second groove, a dimension of the coupling member being expandable to a first value due to heating the coupling member and retractable to a second, nominal value due to cooling the coupling member, the coupling member exerting a force to secure the bracket to the support arm when the dimension is the nominal value.
