Description

FIELD OF THE INVENTION [0001] The present invention relates to a guiding structure for guiding a magnetic levitation train,

The present invention relates to a guideway structure for a magnetic levitation train, and more particularly, to a guideway structure for a super high-speed suction levitation train driven by a linear synchronous motor (LSM) Bracket is provided on a concrete girder in a buried state, and a construction method thereof.

Generally, a Maglev Levitation Train is a train that moves by moving a vehicle on a track by using a magnetic force. The support and drive guidance function performed by a wheel in a general railway vehicle is applied to an electromagnet and a track structure And is performed by the magnetic force between the guide rails installed.

In order for these maglev trains to move, it is necessary to have the power to lift the train from the track and the two forces to move the train in the desired direction. The method of floating the train on the track can be classified into Electrodynamic Suspension using the repulsion force of the magnet anode and Electromagnetic Suspension using the attraction force between the magnet and the magnetic body. Generally, rebounding has advantages in terms of control rather than absorption, but at low speeds the induced flux in the coil is not enough to lift the car, so the wheels should be used at speeds below about 100 km / h. On the other hand, the suction-and-recognition trains have the advantage of being able to control the lift force of the vehicle to keep the balance, but to be able to be injured even in low speed.

Since the magnetic levitation trains do not have direct contact with the guide rails, they are very popular in the next generation train system in urban areas because they have very little noise and vibration, do not emit pollutants, are environmentally friendly, and can maintain high speed. Especially, when constructing an urban type magnetic levitation train in the city, it is common to install a bridge at a considerable height from the ground by installing a bridge so as not to be disturbed by the facilities on the ground because the space to construct is narrow.

In Korea, since the research and development started in 1989, magnetic levitation trains have been developed through the commercialization project of an urban type magnetic levitation train, which was started in 2006, and test lines were built at Incheon International Airport in 2011. The magnetic levitation trains developed through this commercialization project use a levitation method using a superconducting electromagnet and have a running speed of 110 km / h. Especially, Incheon International Airport urban type magnetic levitation railway is guided by a medium induction motor (linear induction motor: LIM) guiding way for a suction type magnetic levitation train.

1 is a view illustrating a guiding structure for a suction type magnetic levitation train of the LIM type according to a conventional technique.

Referring to FIG. 1, a conventional guiding structure for a suction type magnetic levitation train of a low-speed LIM type includes a plurality of bridge columns 10 supported at a lower portion thereof; A girder 20 provided at the upper portion of the pier 10 and installed continuously; A plurality of cross arms 30 installed at intervals on the upper portion of the girders 20; And a guide rail 40 installed at an upper portion of the cross arm 30 to enable the magnetic levitation train to be operated.

A plurality of crossarms 30 are installed on the girder 20 at intervals in the longitudinal direction. The crossarms 30 are fastened and fixed to the guide rail 40 through the fastening member 41. At this time, the fastening member 41 uses a bolt (or an anchor bolt) and a nut.

Since the guideway structure for the suction and the magnetic levitation train of the medium and low-speed LIM type according to the conventional technique is installed in the air, sagging occurs over time and deformation due to temperature occurs.

Therefore, when the installation position of the initially installed guide rail 40 is deformed, its position must be adjusted in order to correct it. In the conventional guide way structure, the guide rail 40, In order to finely adjust the position of the guide rail 40 in the vertical and horizontal directions, it is necessary to raise the guide rail 40 by using a device such as a hydraulic jack to adjust the position of the guide rail 40 The liner 42 or the like is adjusted between the guide rail 40 and the cross arm 30 or the bottom surface of the cross arm 30.

Therefore, even when fine adjustment is necessary due to deformation of the rail during initial installation as well as after use of the rail, the guide rails 40 are lifted using the equipment, and the liner 42 is repeatedly removed Therefore, the operation is very troublesome, requires highly skilled technology, and it takes a lot of time and cost to install the track structure.

When a deformation in the horizontal direction occurs on the basis of the guide rail 40, if a means for correcting the deformation in the horizontal direction is not provided, if the deformation is severe, the guide rail 40 of the corresponding section is taken out and a new guide rail 40).

The conventional guiding structure for a suction type magnetic levitation train is a guideway applied to a medium-speed linear induction motor (LIM) type, which is difficult to apply to a super high-speed magnetic levitation rail guideway.

Recently, super high-speed magnetic levitation trains with speeds of more than 500 km / h have been developed. Currently developed ultra-high-speed magnetic levitation trains include Japan's MLX using a superconducting system in a floating mode, and Translaid Transrapid), and both of these methods use a linear synchronous motor (LSM) as the propulsion method. For example, the propulsive force of a system moving with electromagnetic force such as a transreflector in Germany is supplied by an LSM having a stator fixedly arranged along a guideway, and a moving magnetic pole for generating a magnetic flux for floating It is installed in the assembly of the floating train.

Specifically, the magnetic levitation electromagnet is composed of a linear synchronous motor stator provided on the ground side guideway structure side and a mover provided on the assembly side of the magnetic levitation train. Specifically, a guideway for supporting the magnetic levitation train is provided on the ground, and a stator of the linear synchronous motor (LSM) is installed toward the ground along the entire guideway. A floating electromagnet attached to the vehicle is placed against the stator. When the current is applied to the levitation electromagnet, the levitation force is generated and the direction of the magnetic flux is alternately indicated as the direction of the magnetic flux along the traveling direction so that it is used as the shifter of the linear synchronous motor (LSM). At this time, a guide electromagnet is used on both sides of the assembly of the magnetic levitation train to compensate the external lateral force due to rotation, disturbance, and the like.

In addition, in the case of a Shanghai Maglev train in China, a guideway for an ultrasonic LSM-type suction / pickup maglev train is applied and will be described with reference to Figs. 2A, 2B, and 3. Fig.

The stator packet 72 and the motor coil windings 73 are attached to the lower portion of the guide rail 60, do.

2B, steel brackets 71 are arranged at regular intervals, and the guide rails 60 are fastened so as to enclose the steel brackets 71. As shown in Fig.

FIG. 3 is a detailed view of a portion indicated by reference symbol A in FIG. 2A. In the case of a guideway structure for a suction and a magnetic levitation train driven by an ultra-high speed LSM system according to the related art, as shown in FIG. 3, The cement 71 is buried at the time of curing of the concrete girder 20. Due to the deformation, it is difficult to tighten the bolt as the fastening member 74 as shown by the reference numeral C, There is a problem that it is difficult to tighten with a tool or a hand because the space is narrow. In addition, there is a problem that it is difficult to fine-tune for correcting the height and height difference with respect to the X-axis, Y-axis and Z-axis at the time of installation of the guideways. In addition, when the concrete girder 20 is applied, there is a problem that it is difficult to install a bolt fastening operation or the like due to sagging due to the weight of the guide way. Further, there is a need for a separate device for precise positioning of the bracket 71 and accommodating the tolerance in the concrete curing of the concrete girder 20 which is precastly manufactured at the factory. That is, there is a problem that a device for precision and fixing of a form is separately required.
