Definitions

  • the present invention relates generally to railway maintenance. More specifically, the present invention is directed to an apparatus and related methods for milling a track surface to remove irregularities in the track surface.
  • Rail tracks generally comprise a pair of metal rails arranged in a parallel configuration so as to guide and support metal wheels of train cars.
  • Use of these tracks to support heavy loads travelling at high speeds results in the formation of irregularities such as pits, burrs, cracks and deformations along the track surface.
  • irregularities can create excessive noise and vibrations as the wheels of the train car contact the irregularities.
  • the irregularities can also increase the fatigue on the rails and the train cars themselves creating substantial safety and maintenance problems.
  • the irregularities can often be easily smoothed out of the track by grinding or milling the surface of each track section in a machine shop, removing each section for regular maintenance is impractical and expensive.
  • a common method of removing irregularities from the track in situ comprises pulling at least one rotating grinding stone that includes an abrasive surface along the track to grind the track surface so as to smooth out any irregularities without having to remove the section.
  • One of the primary concerns with grinding out the irregularities without removing the track section is ensuring that the entire track surface is contacted by the abrasive surface so as to avoid missing any irregularities. Because of factors including different load weights and configurations of the trains traveling over the rails or even installation factors such as, for example, differing soil conditions beneath the rails, the track surface can wear unevenly along the railway. This makes it even more important that that the entire rail profile be contacted by an abrasive surface during the grinding operation. In response to this requirement, a variety of different grinding configurations have been developed are currently available to grind the entire rail profile.
  • a rotating grinding element rotates in a vertical plane above the rail.
  • the abrasive surface is positioned on a perimeter edge of the rotating element and is beveled or shaped to match the rail profile such that it contacts the entire face of the rail surface as the rotating element is directed along the rail.
  • the drawback of the Type 1 configuration is that the large surface area of the abrasive surface for each rotating element creates a substantial amount of friction requiring a relatively powerful motor to rotate the rotating element.
  • the rotating element is typically rotated such that the abrasive surface travels past the track surface in the direction opposite the direction the rotating element is being pulled down the track to maximize the friction generated by the abrasive pad so as to efficiently grind the track surface. While maximizing the effectiveness of the abrasive pad, the friction created by the grinding acts as a brake slowing the grinding process, which can lead to increased amounts of downtime for the rail line being grinded.
  • the amount of power required to rotate the rotating element and the braking effect of the abrasive surface are both reduced by positioning the abrasive surface on the plane of the rotating element instead of the edge.
  • the rotating element is positioned against the track surface such that the rail approximately bisects the center of the rotating element.
  • the abrasive surface creates a desirable grinding pattern in which the abrasive surface is drawn across the rail surface perpendicular to the rail rather than parallel to the rail.
  • the abrasive surface of an individual rotating element only contacts a single facet of the rail profile, which significantly reduces the amount of power required to rotate the rotating element.
  • a Type 3 grinding configuration somewhat resembles the appearance of a Type 2 grinding configuration in that it also utilizes a plurality of rotating elements with each rotating element rotating in a different plane so as to engage an individual facet of the rail profile rather the entire track surface.
  • the rotating elements of the Type 3 configuration are beveled proximate to the edge of the rotating elements such that the rotating elements can rotate in planes that do not prevent the rotating element from being used in track sections having encumbrances such a roads or platforms.
  • the Type 3 configuration is currently used with grinding processes where the abrasive surface can be easily beveled or shaped to properly contact the track surface.
  • the inherent tradeoff between the Type 2 and Type 3 configuration is that because the abrasive surface of the Type 3 configuration is at the edge of the rotating element, the abrasive surface is drawn across the track surface parallel to the track rather than the more desirable perpendicular grinding pattern found with the Type 2 configuration.
  • the contact between the abrasive grinding pad used in all grinding processes and the metal track surface creates a substantial amount of heat and sparking.
  • most grinding systems for rail lines are required to include fire suppression systems for combating any fires resulting from sparking along the track.
  • the potential fire risk posed by grinding processes has led to a recent trend in track maintenance to use a milling process to maintain the track instead of a grinding process.
  • a milling process uses rotating blades and/or bits to mill down the track surface to remove irregularities rather than using friction generated by an abrasive pad. Milling processes generate less heat and sparking than grinding processes, thereby minimizing the risk of fire.
  • a drawback of milling processes is that the rotating blade or bit assembly must be carefully monitored as the blade or bit can easily cut too deeply into the track surface reducing the operating life of the track or creating an irregularity rather than removing the irregularities.
  • the milling blade or bit can become broken or dulled from repeated use. Replacing a broken blade or bit can cause significant delays if the blade or bit breaks in a remote location and a new blade assembly must transported to the work site.
  • the present invention is directed to a railway milling system that can be pulled along sections of track and comprises a plurality of milling plates, each plate including a plurality of milling blades for engaging the track surface so as to remove irregularities from the track surface.
  • the plurality of milling blades are generally arranged along the periphery of the milling plate.
  • the milling blades can be oriented above a length of rail such that the milling blades contact and mill the rail in a perpendicular orientation to the rail along sections of track that lack encumbrances.
  • the milling blades can be angled and oriented such that milling blades contact and mill the rail in a parallel orientation to the rail along sections of track that include encumbrances such as, for example, roads or platforms.
  • Each milling plate can comprise a modular blade assembly including a plurality of individual locking slots, each locking slot corresponding with a single milling blade.
  • the locking slots allow individual milling blades to be easily removed and replaced if a blade becomes dull or broken.
  • the modular blade assembly reduces down time required for the replacement of broken blades and increases the useful life of the milling plate as the individual milling blades can be replaced instead of the entire milling plate.
  • a rail milling system can comprise at least one milling module having a plurality of milling plates with each milling plate including a motor for rotating the milling plate.
  • Each plate comprises a plurality of individual milling blades and a plurality of locking slots positioned along the periphery of the milling plate, each locking slot being adapted to releasably receive one of the milling blades.
  • Each locking slot can further comprise an adjustable vice for individually gripping the corresponding milling blade.
  • the milling module can comprise a positioning assembly for each milling plate such that the milling position and angle of milling plate can be controlled and adjusted.
  • the positioning assembly can position each milling plate above a length of rail so as to contact and mill the rail in a perpendicular orientation for lengths of track that are free of encumbrances.
  • the positioning assembly can angle each milling plate above the length of rail so as to contact and mill that rail in a parallel orientation for lengths of track that include encumbrances.
  • each of a plurality of milling plates is positioned at a unique angle such that each milling plate mills a unique facet of a rail profile.
  • the plurality of milling plates cooperatively mill the entire rail profile as a milling module traverses a length of rail.
  • the milling plates can be positioned such that an edge portion of each milling plate engages the rail to provide a parallel milling pattern such as when encumbrances are present or alternatively, the milling plates can be positioned over the rail such that the rail bisects or nearly bisects the center of the rotating milling plate to provide a perpendicular milling pattern.
  • a rail milling system can further comprise at least one depth guide adapted to contact a rail surface as a milling module is being pulled down the rail surface.
  • the depth guide can operably attached to each of the milling modules so as to prevent individual milling blades of the milling module from cutting too deeply into the track surface.
  • the depth guide is positionable to control a maximum milling depth of the milling module thereby controlling the extent to which the milling blades cut into or mill the track surface.
  • a method for milling a track surface can comprise providing a rotatable milling plate having a plurality of locking slots each adapted to receive a milling blade.
  • the method can further comprise attaching a milling blade into each of the locking slots and positioning the milling blade to present a milling surface that is angled relative to a plane of the milling plate.
  • the method can also comprise positioning the milling plate such that the plurality of milling blades engage a track surface, either in a parallel or perpendicular orientation to the track surface, dependent upon track surroundings such as, for example, the presence of encumbrances.
  • the method can further comprise rotating the milling plate to cut or mill the track surface and remove irregularities from the track surface.
