  • Patent number: 10429180
    Abstract: Provided is versine trolley-type equipment for inspecting a track irregularity, having sensors respectively provided to a trolley so as to measure a height difference, direction misalignment, gauge irregularity, rail longitudinal slope, cant and the like of railroad rails, and simultaneously measuring the height difference and direction misalignment of a left rail and a right rail so as to reduce a measurement time by half and, also, allowing left and right measurement frames to freely move in a vertical direction within a predetermined range, thereby bringing front and rear trolley wheels of the left and right measurement frames into close contact with the rails all the time even if the rails are warped.
    Type: Grant
    Filed: February 22, 2016
    Date of Patent: October 1, 2019

  • Patent number: 8505463
    Abstract: The wheel-type high-speed railway system includes rails provided on a railroad track and configured such that wheels provided in a bogie of a vehicle come into contact with them, a support provided on a tread surface of a railroad track between the rails, a repulsive Linear Synchronous Motor (LSM) provided between the bogie and the support and configured to improve traveling performance by reducing axle load in a high-speed region, first and second steel plates mounted on both sides of the support in inclined positions, and first and second attractive Dynamic Motion Control (DMC) magnets mounted on the bogie of the vehicle in inclined positions to correspond to the first and second steel plates, and configured to generate attractive force.

  • Patent number: 8468949
    Abstract: Provided is a tube railway system that reduces noise and air resistance using a sealed evacuated tube as a passage for a tube railway, thereby allowing a train to run at a higher speed. A vacuum division management system and a vacuum blocking screen device for a tube railway system required to maintain vacuum are provided, in which the vacuum blocking screen device is operated to rapidly block a passage for a tube railway in response to an operation signal, is installed at every certain section or at a designated section of the tube railway, and is operated in a specific section when a vacuum maintenance problem occurs, or when the vacuum needs to be released, or when the train needs to stop immediately, thereby allowing the specific section to be isolated from other sections to have a degree of vacuum different from those of the other sections.

  • Publication number: 20110283914
    Abstract: Provided is a tube railway system that minimizes noise and air resistance using a sealed evacuated tube as a passage for a tube railway., thereby allowing a train to run at a very high speed. More particularly, provided is a vacuum division management system and vacuum blocking screen device for a tube railway system required to maintain vacuum (1/3 to 1/1000 of atmospheric pressure), in which the vacuum blocking screen device serves to rapidly block a passage for a tube railway with an operation signal, is installed in every fixed section or in some designated sections of the tube railway, and is driven in a specific section where problems with maintenance of the vacuum occur, where the vacuum is intentionally released, for instance, due to maintenance, or where a train is urgently stopped, thereby allowing the specific section to be isolated from the other sections and to be managed with a degree of vacuum different from those of the other sections.
