Estimating the term…
In the formation of finished slide surfaces for slide rails on a track for an electromagnetically levitated vehicle, the track is constructed as a girder-like beam with the slide rails located on cantilevered parts of the upper surface of the beam. The beam can be formed of prestressed concrete. Initially the slide rails are provided with a height oversize. The height oversize part of the slide rails is removed and the slide surface of the rails are finished to the desired degree. The height oversize part is removed by cutting and grinding devices mounted on a machine frame movable over the upper surface of the track. The machine frame is adjustable in the vertical direction from a datum plane formed by the lower surfaces of support stators secured to the undersides of the cantilevered parts of the track. The machine frame rides on the upper surface of the beam and is in contact with the lower surfaces of the support stators.
Apparatus for forming slide surfaces on slide rails on a track for electromagnetically levitated vehicles with the track formed as an elongated girder-like beam constructed of at least one of steel, reinforced concrete and prestressed concrete with the beam having an upper part with an upper surface and a base extending downwardly from the upper part, the upper part being cantilevered laterally outwardly from the base and forming longitudinally extending cantilevered parts, the slide rails located on and extending upwardly from the upper surface of the cantilevered parts and the slide rails being formed with a height oversize part extending upwardly in a height direction from the upper surface of the cantilevered parts, support stators located on an underside of the cantilevered parts below the slide rails with the support stators having a lower surface, comprising a machine frame movably supported on the upper surface of the upper part, said machine frame being adjustable in the height direction of the slide rails, means mounted on said machine frame for removing the height oversize part of the slide rails and then for forming a sliding surface on the surface of said side rails, said machine frame arranged to extend downwardly from the upper surface of the upper part and to be adjustable for contacting the lower surface of the support stators with the lower surface forming a reference plane for said means in removing the height oversize parts, and means on said machine frame for controlling the height adjustment as a function of contact pressure force on the lower surface of said support stators.
Facility for forming slide surfaces on slide rails on a track for electromagnetically levitated vehicles with the track formed as an elongated girder-like beam constructed of at least one of steel, reinforced concrete and prestressed concrete with the beam forming the track having an upper part with an upper surface and a base extending downwardly from the upper part, the upper surface being cantilevered laterally outwardly from the base and forming cantilevered parts, the slide rails located on and extending upwardly from the upper surface of the cantilevered parts and the slide rails being initially formed with a height oversize part extending upwardly from the cantilevered sections, support stators located on the underside of the cantilevered part below the slide rails with the support stators having a lower surface, comprising first means forming an elongated first support station for a section of track having a first end and a second end spaced apart in the elongated direction, second means forming an elongated second support station extending in alignment with an outwardly from the first end of said first support station, third means forming an elongated third support station extending in alignment with and outwardly from the second end of said first support station, a machine frame with means thereon for removing the height oversize part of the slide rails on said section of track positionable in and movable between said first, second and third support stations, support means for placing and removing a section of track onto and from said first support station and for transporting the section of track to and from the first support station, said machine frame including means for moving said machine frame from said second support station to said first support station and then to said third support station and then for returning the machine frame over the first support station to the second support station so that in such movement over the first support station a number of working operations can be effected on the slide rails from the machine frame for removing the height oversize part and then for forming a sliding surface on the slide rails.
