Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a propulsion and guide coil device for a superconducting magnetically levitated vehicle.

[Technical background of the invention and its problems]

Currently, the development of levitation trains using superconducting electromagnets, that is, superconducting magnetic levitation vehicles, is progressing, and many results have been obtained and bright prospects have been established. Considering the actual vehicle configuration, it has come to be thought that it is preferable to have a U-shaped track for the track, and test vehicles have shown that iJ! Experiments and theoretical analyzes are driven by the U-shaped cross-section trajectory. Figure 1 is a cross-sectional view of the current test vehicle and its track, where 1 is the vehicle body, and 2.2 is the left and right parts attached to both sides of the bogie frame 4 that supports the vehicle body 1 via air springs 3, 3. This shows a superconducting electromagnet. The ground side coil facing this is the U-shaped section track 50 side walls 5A.

A propulsion guide coil 6°6 is embedded in the opposite surface of the 5A.
Further, levitation coils 2.7 are arranged in rows along the entire length in the traveling direction on the left and right sides of the upper surface of the bottom wall 5B. The levitation coil 7.7 causes a levitation blade, and the propulsion guide coil 6.
A propulsion guiding force is applied by the vehicle 1 to propel the vehicle 1 together with the bogie frame 4. Here, when running at high speed, there is no contact with the track 5, but when running at low speed, neither the floating blade nor the guiding force is sufficiently generated, so the running wheels 8, 8 and guide wheels 9 protruding from the bogie frame .9 runs in rolling contact with the 5th track surface. In the case of a superconducting magnetic levitation vehicle having such a configuration, if an abnormal condition occurs during high-speed running, the running wheels 8.8, guide wheels 9.9, or emergency sliding mechanism (not shown) may be placed on the surface of the track 5. Since the running wheels 8.8 of the bogie frame 4 can be arranged within the levitation coils 7.7, the levitation coils 1 and 1 do not come into contact with the wheels 8 and 8. Therefore, no special structural consideration is required. However, it is conceivable to install the guide wheels 9 on both sides above the propulsion guide coil C, but considering the υ-shaped cross-section track 5, the moment received by the side walls 5m will be smaller if they are located as low as possible. For constructional reasons, it is provided at the same height as the propulsion guide coil 6, as shown in FIG. In such a case, there is no problem while floating and propulsion is running in a non-contact state, but due to low-speed running or an abnormal situation, the wrinkle guide wheel 9 or the sliding sea (not shown) may land on the vehicle side surface of the propulsion guide coil 6 and slide. Therefore, the propulsion guide coil 6 will be damaged unless it has a structure that can withstand skidding. For this purpose, the propulsion guide coil d
requires some kind of structural consideration, but currently no good idea has been proposed anywhere.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a propulsion and guide coil device that does not require any special manufacturing process when molding and manufacturing a propulsion and guide ground coil.

[Structure of the invention]

The present invention is a propulsion guide coil device arranged in a row on a side wall portion of a U-shaped cross section, and is provided with a propulsion guide coil body formed by molding with the coil inside, on the surface portion of the mold layer on the side facing the vehicle bogie. .

The special attack is constructed by providing a smooth reinforced strip-shaped sliding surface extending in the propulsion direction on which the guide wheel or sliding seam protruding from the bogie frame can roll or slide.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the 1/X2 diagram and FIG. 3. Note that FIG. 2 is a perspective view of the propulsion and guide coil device alone, and FIG. 3 is a sectional view of the propulsion guide coil device as it is attached to the side wall of the U-shaped cross-sectional track.

Here, reference numeral 10 in the figure is a propulsion and guide coil main body formed by molding the entire body with the coil 6m inside, and the mold layer 1 (insulating layer) of the main body 10 has a substantially rectangular frame shape with a hollow center. A flange portion 12 in the shape of a quadrilateral flange is integrally formed on the side facing the bogie underframe. The flange portion 120 is further located on the surface side and is provided with a smooth reinforced band-shaped sliding surface in a thick state in a band-like state in the horizontal direction, that is, in the propulsion direction, at the part where the guide wheel or sliding nose protrudes from the bogie frame. IS is integrally molded. This strip-shaped sliding surface 13 has a reinforced structure with, for example, glass cloth arranged inside so as to have wear resistance and strength. In addition, 14 and '15 in the figure indicate the propulsion guide coil main body 10.
(The DU-shaped cross-section raceway is attached to the side wall surface using a single-purpose bolt seat, and S-root seats 14° 14 are provided integrally with the mold layer 1 on the inner left and right rear surfaces of the main body 10, It is reinforced by flg and 17 so that it can withstand sufficient force to receive the hoop force acting on the coil 6A and the reaction force of the force that propels and guides the vehicle. The center portion between the seats 14' and 14 is an opening 18 that penetrates from the front to the back, and serves as a space for inserting the shim 20 into the back side when tightening the bolt 19. The lower bolt seats 15.15 are provided on the lowermost left and right sides of the flange portion 12, avoiding the sliding surface 13, so that two bolts 21 can be attached. This is a shim that is inserted from the bottom to the back side when tightening.In addition, 23 has a seat hole for installing the cover.
A non-metallic cover 24 is attached to close the open direction of the flange portion 12 of the main body 0, except for the strip-shaped sliding surface 13, so that the surface of the flange portion 12 is made as smooth as possible.
It is now possible to 25 is a space formed by leaving the lip j5A on the back side of the sliding surface 13, and is strong enough to withstand the force received from the sliding surface 13. Reference numeral 26 denotes a lead wire coming out from the coil 6A in the propulsion guide coil main body 1o, and although it is drawn out downward as shown in the figure, it is fully conceivable that it may be drawn out from the top or the back side in relation to the track structure. Also the third
As shown in the figure, a recess #I27 is formed in the side wall 5A of the U-shaped cross-sectional track, into which the propulsion guide coil main body 10 is fitted, leaving the flange portion 12. A screw seat for the I-seat hole; #29 is embedded and fixed in the concrete.

In the propulsion guide coil device of the present invention, when constructing the U-shaped cross-section track, the protrusion for concave@27 and the screw seat 211. After the concrete of the U-shaped cross section track hardens, the formwork is removed with the seat hole screw seat III, '29 left in the concrete, and in that state, the propulsion guide coil body jOt - its mold layer 1 node is removed. is inserted into the recess #I27 of the side wall 5A of the U-shaped cross-section track, and in that state, the shim 20, 22
is inserted on the back side of the main body 10 and tightened with two bolts 19 and 21, and the propulsion guide coil main body 10 is attached to the side wall shl! ! ]1I
The flange portion 12 and the strip sliding surface 13 are joined and aligned to form a continuous surface with that of the adjacent propulsion guide coil body. At this time, if there is a gap between the flange part J2 and the side wall surface, use a foam sealant or a general sealant such as mortar to prevent the intrusion of rainwater and the noise caused by the inflow of vehicle wind. I do. After the above-described installation work is completed, the six central open faces of the flange portion 12 are closed by the installation of the cover 24, so that the entire surface becomes a substantially smooth surface.

With the above steps, installation of the U-shaped cross-section track to the side wall 5A has been completed, and the propulsion guide coil device faces the superconducting magnet of the vehicle bogie frame and functions to provide propulsion guide force in the same way as the conventional one. As a result, the vehicle travels at high speed, and the running wheels and guide wheels of the vehicle are retracted and do not contact the track surface at all during normal high speed travel. By the way, when the vehicle is running at low speed or when a problem occurs with the superconducting electromagnet or other equipment that plays an important role in running, the guide wheels or sliding seams that protrude from the bogie frame can be removed from the mold of the main body 10 of this device. The layer 12 comes into contact with the smooth reinforced strip-shaped sliding surface 13 to transfer or slide. In particular, if one of the left and right superconducting electromagnets suddenly moves during high-speed running and causes a collision, the guide wheels are in the situation 11, so the sliding sheave suddenly hits the sliding surface 13 directly and slides at high speed. Begins to move. On the other hand, from the sliding surface zs'1dlk@, there is a pedestal that is held integrally with the mold layer 11 and flange portion 12 of Reso 2B11, has a reinforcing member such as glass cloth arranged inside, and protrudes from the flange portion 12. (Since it is thick-walled, it is possible to smoothly transfer or slide the guide wheel or sliding shear to perform guidance without causing damage from the strong impact of the sudden sliding shear, as well as the rolling of the guide wheel. Moreover, damage to the mold layer 1 of the main body 10 is also prevented. In addition, according to the propulsion guide coil device having such a configuration, the different surface side strip-shaped sliding surfaces 13 of each main body 10 arranged in the traveling direction are arranged in a polygonal line in the bent track section, but in this type of floating vehicle, the curve radius is Since it is extremely large, it becomes a band-like continuous flat state that cannot be described as a polygonal line.

In addition, the open surface on the front side of the fledge portion J2 of the propulsion guide coil main body 10 is closed by the cover 24 to hide the internal uneven structure, resulting in a smooth surface structure, so that the vehicle can move around the propulsive guide coil body 10. It is possible to prevent the occurrence of turbulence in the boundary layer airflow that moves with the rolling stock, and it is possible to reduce noise and increase in running resistance, which can be expected to be effective in reducing noise and loss as a floating railway. Become.

In addition, since the propulsion and guide coil device is an electrical structure and issues with insulation and strength, it is thought that the lifespan will be shorter than that of the track structure, but if the electrical insulation deteriorates, it can be easily replaced 4 hours 8, so it can be used for track maintenance etc. It is also a very advantageous device.

4 and 5 show a modification of the present invention, in which the propulsion guide coil main body 10 is exactly the same as the embodiment shown in FIGS. 2 and 3, but the strip-shaped sliding surface 13 is It is constructed by attaching a plate material 30, such as Teflon, which has a low coefficient of friction and excellent wear resistance. That is, main body 1
0, protrusions 31 and 32 are formed above and below the sliding surface forming part on the surface of the flange part 12, and grooves S
3, and a plurality of dovetails d134 are provided protruding from the bottom surface of the dovetail groove 33, and the plate material 30 is fitted into the dovetail groove 33 so as to engage with each dovetail I3, 4. By putting them together, they constitute a strip-shaped sliding surface No. 3. This poses no problem even if the sliding seams or wheels on the vehicle side slide or roll, resulting in an advantageous product with excellent durability.

[Invention effect]

As described in detail above, the present invention is provided with a smooth reinforced strip-shaped sliding surface on the surface thlH of the molded propulsion guide coil main body on which the guide wheels or sliding seams protruding from the vehicle bogie move or slide. Even if the sliding shear moves or slides, the propulsion guide coil main body is reliably maintained, and has an extremely convenient structure as a propulsion guide coil device with a U-shaped cross-section track.
