Abstract
A portable apparatus for configuring a wheel associated with a track is provided. The apparatus is in a fixed position with respect to a rail associated with the track when in operation. The apparatus includes a tool configured to engage the wheel, a position system for positioning the cutting tool in at least two axis, and a computer control. The computer control is coupled to control the positioning system. The positioning system is controlled so that the wheel is configured in accordance with a profile.
Claims15
A portable apparatus for profiling a first wheel of a locomotive or train car, the first wheel being part of a first pair of wheels disposed on a track with a first rail and a second rail, the first pair of wheels comprising the first wheel on the first rail and a second wheel on the second rail, wherein the locomotive or train car comprises a second pair of wheels disposed on the track, the second pair of wheels comprising a third wheel on the first rail and a fourth wheel on the second rail, the apparatus comprising:
- a base, the base being releasably attached to the first rail, the second rail or both the first and the second rail;
- a cutter;
- a positioning system for moving the cutter relative to the first wheel along at least two axes;
- a jack for lifting the first wheel from the first rail and free from the base wherein the jack lifts the second wheel in the first pair of wheels from the second rail when the first wheel is lifted from the first rail, wherein the second wheel is connected to the first wheel through an axle, and wherein the first wheel is lifted so that at least the second pair of wheels remain on the first and the second rails;
- and
- a computer control configured to control the positioning system, wherein the positioning system is controlled so that the first wheel is profiled to a desired profile, wherein the first wheel is free to spin without contact with the portable apparatus except at the cutter.
A portable system for profiling a first wheel of a first pair of wheels mounted on an axle and disposed on a track with a first rail and a second rail in accordance with an electronically stored profile, the system comprising:
- a jack for raising the first wheel while allowing one or more second pairs of wheels to engage the track, the jack raising the first wheel by raising a second wheel of the first pair of wheels and through the axle without contacting an outside rolling surface of the first wheel;
- a cutting tool disposed on the track and configured to engage the first wheel;
- a positioning system for positioning the cutting tool;
- and
- a control for controlling the positioning system, wherein the positioning system is controlled so that the first wheel is profiled to the electronically stored profile.
