Abstract
A transportation apparatus configured to travel on rails and having an induced freezing rail system includes: a transportation vehicle having a support unit configured to support a frame from the rails; and a freezing rail system comprising freezing rails positioned on a ground surface corresponding to the support unit of the transportation vehicle, the freezing rails having a refrigerant and cooling devices.
Claims10
A transportation apparatus comprising:
- a transportation vehicle having a frame and a support unit configured to support the frame;
- a freezing rail system comprising a freezing rail on which the support unit is disposed, the freezing rail having a refrigerant and a cooling device,
- wherein the transportation vehicle further includes a front antenna and a rear antenna that are configured to transmit radio waves for inducing freezing of the freezing rail, and
- the freezing rail system further includes a sensor configured to actuate the cooling device based on wireless communication with the front and rear antennas.
A transportation apparatus comprising:
- a transportation vehicle having a frame and a support unit configured to support the frame;
- a freezing rail system comprising a freezing rail on which the support unit is disposed, the freezing rail having a refrigerant and a cooling device,
- wherein the support unit comprises a frame blade inserted into the refrigerant and a shock absorber coupled to a top of the frame blade.
A transportation apparatus configured to travel on freezing rails, comprising:
- a transportation frame having frame blades configured to move on the freezing rails and a support unit for the frame blades;
- a front antenna positioned on a front portion of the transportation frame to transmit a signal for inducing freezing of the freezing rails before the transportation frame reaches the freezing rails;
- and
- a rear antenna positioned on a rear portion of the transportation frame to transmit a signal for releasing freezing maintenance of the freezing rails after the transportation frame passes through the freezing rails.
An induced freezing rail comprising:
- a groove extending from a ground surface in a narrow and deep shape;
- a refrigerant filling the groove;
- a cooling device positioned on an outer periphery of the refrigerant;
- refrigerant protective film formed on top of the groove;
- a sensor configured to actuate the cooling device;
- and
- a metal rail formed on an upper outer periphery of the groove.
