Abstract
A guide shoe for a mining machine includes a shoe body, a through hole, and a support. The shoe body is configured to engage a rack. The through hole extends between a first wall of the shoe body and a second wall of the shoe body, and the through hole extends along a central axis. The support is coupled to the first wall, and the support is configured to engage a shaft coupled to a drive sprocket engaging the rack. At least one of the shaft and the support is movable between a first configuration and a second configuration. The rotation axis is spaced apart from the rack by a first sprocket distance in the first configuration, and the rotation axis is spaced apart from the rack by a second sprocket distance in the second configuration.
Claims21
A guide shoe for a mining machine, the guide shoe comprising:
- a shoe body having a first end and a second end, the shoe body configured to engage a rack;
- a through hole extending through a first wall of the shoe body and a second wall of the shoe body, the through hole extending along a central axis;
- and
- a support coupled to the first wall, the support configured to engage a shaft supporting a drive sprocket engaging the rack, the support includes a pin slot having a first slot edge and a second slot edge opposite the first slot edge, the pin slot having a slot center point that is vertically offset from the central axis.
A drive mechanism for a mining machine configured to engage and move the mining machine along a rack, the drive mechanism comprising:
- a sprocket configured to engage the rack, rotation of the sprocket configured to move the mining machine relative to the rack;
- a shaft supporting the sprocket for rotation about a rotation axis;
- a guide shoe configured to maintain engagement between the sprocket and the rack, the guide shoe having a shoe body including a first end, a second end, a rack slot extending between the first end and the second end along a rack slot axis, a first wall, a second wall spaced apart from the first wall, and a through hole extending through the first wall and the second wall along a central axis;
- and
- a support coupled to the shoe body, the support including a shaft slot having a first slot edge and a second slot edge opposite the first slot edge, the shaft slot having a slot center point, the support coupled to the shaft,
- wherein at least one of the shaft and the support is movable between a first configuration and a second configuration, the rotation axis being spaced apart from the rack by a first sprocket distance in the first configuration, and the rotation axis being spaced apart from the rack by a second sprocket distance in the second configuration.
A guide shoe for a mining machine, the guide shoe comprising:
- an elongated shoe body including a first end, a second end, a slot extending between the first end and the second end along a rack slot axis, a first lug, and a second lug spaced apart from the first lug, the first lug including a first opening extending along a central axis, and the second lug including a second opening that is aligned with the central axis;
- a shaft for supporting a sprocket for rotation about a rotation axis, the shaft including a first end and a second end;
- and
- a pair of supports including a first support and a second support, the first support coupled to the first lug and engaging the first end of the shaft, the second support coupled to the second lug and engaging the second end of the shaft,
- wherein at least one of the shaft and the pair of supports is movable between a first configuration and a second configuration, the shoe body being supported in a first position relative to the sprocket in the first configuration, and the shoe body being supported in a second position relative to the sprocket in the second configuration.
