Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for laying a reaction plate for a linear motor vehicle that runs using magnetic attraction.

[B] Prior Art A method of driving a vehicle using magnetic attraction has been developed.

This running method uses rails and reaction plates (secondary side) on concrete sleepers.
are laid continuously to form a running track, and a vehicle equipped with a linear motor (primary side) is mounted on this rail via wheels.

By generating an attractive force by magnetic force between a reaction plate fixed to the sleeper and a linear motor, the vehicle is positively pressed against the rail side and moved forward by the magnetic force.

By using this combination of wheels and rails, it has become possible to significantly improve stability.

[B] Problems to be Solved by the Present Invention By the way, the following problems exist in the conventional reaction plate laying technology.

(1) As shown in Figures 5 and 6, the reaction plate A must be laid with continuity even at the branching sections (point sections) of the track.

However, the reaction plate A is connected to the rail R.
Even if the blade B formed at the hem of the reaction plate A collides with the lower plate R1 of the rail R, or the fastener between the blade B and the rail R, the reaction plate A
The conductive plate C on the top surface of the rail cannot be brought sufficiently close to the rail R side.

As a result, a zone where no reaction plate is placed occurs.

The longer the distance in which the reaction plate is not laid, the greater the dependence on coasting, which poses a problem in terms of running.

The present invention was created in view of the current situation,
The purpose of the present invention is to provide a structure for laying a reaction plate in a magnetic attraction system, which allows the reaction plate to approach the rail as close as possible at a branch part.

[C] Means for solving the problem The present invention provides a support member formed with a width narrower than the transverse width (traverse direction of the track) of the reaction plate.
The present invention relates to a technical means for solving the above problem by supporting and fixing a reaction plate to a sleeper.

[D] Example Hereinafter, an example of the present invention will be described with reference to the drawings. First, each member used in this example will be described.

(1) Reaction plate (Fig. 1) The reaction plate 2 is a plate with a conductive surface 22 formed on the upper surface of a band-shaped iron plate, and legs 21 are formed by extending both skirts in the longitudinal direction of this band-shaped plate. form.

A long hole or a plurality of circular holes extending in the transverse direction of the track are formed in the plate surface of the leg portion 21.

It is attached to the horizontal plate 5 located in the transverse direction of the track through this hole.

Therefore, the reaction plate installation width l
1 is wider than the width of the conductive surface 22.

(2) Supporting material The supporting material 1 is a member that supports the horizontal plate 5 from below, and is composed of a pedestal plate 3 and legs 4 whose upper part is wider than the bottom part.

(3) Pedestal plate The pedestal plate 3 is a rigid plate for installing the expanded head leg 4 on the sleeper 6 while ensuring stability, and is made of, for example, a steel plate.

This pedestal plate 3 is integrally fixed to the upper surface of the wooden sleeper 6 by bolts, nails, etc.

(4) Head expansion leg The head expansion leg 4 is a support member having a narrow lower width and a wide upper width, and can adopt various shapes.

For example, the expanded head leg 4 can be made into a straight or curved shape by horizontally arranging a single rectangular plate, securing a bottom part 41 at the center of the rectangular plate, and bending both ends of the bottom part 41 upward by nearly 90 degrees. A standing leg portion 42 is formed.

Further, a mounting portion 43 extending in the horizontal direction is formed by bending a portion near the free end of the standing leg portion 42 outward to form an inverted Ω shape.

As will be described later, since the bottom part 41 is attached to the sleeper 2 via the pedestal plate 3, the transverse width l2 of the bottom part 41 is formed narrower than the transverse mounting width l1 of the conductive surface 23, so that the reaction plate 2 is attached to the rail side. Configure it so that you can get as close to it as possible.

Further, on the plate surface of the mounting portion 43, the lower end of a vertical bolt 46, into which a support nut 45 is screwed, is welded 11 and erected.

The vertical bolt 46 is attached to the reaction plate 2
This is an adjustment tool for the purpose of adjusting the vertical mounting position of the horizontal plate 5 that is integrated with the horizontal plate 5.

In addition, the bottom part 41 of the head expansion leg 4 is directly attached to the sleeper 2.
When mounting the base plate 3, the pedestal plate 3 mentioned above can be omitted.

Next, the assembly method will be explained.

(1) How to attach the head expansion legs (Fig. 1) There are two methods to fix the head expansion legs 4 to the sleepers 6.

One of them is to manufacture the head expansion leg 4 on which the reaction plate 2 and the integrated horizontal plate 5 are installed in advance in a factory, and to mount these on the pedestal plate 3, and to attach the pedestal plate 3 and the bottom 4.
This is a method of fixing the contact portion of 1 by on-site welding 12.

The other method is to mount the bottom part 41 of the expansion leg 4 in contact with the pedestal plate 3 before installing the reaction plate 2, and to pass bolts, nails, etc. through the expansion leg 4 and install the sleeper together with the pedestal plate 3. Fixed at 6.

Finally, there is a method for attaching the horizontal plate 5 and the reaction plate 2.

(2) How to attach the horizontal plate (Fig. 1) After passing the vertical bolts 46 through the bolt holes 51 and horizontally suspending the horizontal plate 5 between the vertical bolts 46, tighten the fastening nuts 47 to the vertical bolts 46. The horizontal plate 5 is gripped by nuts 45 and 47 from above and below.

Therefore, by moving the nuts 45, 47 up and down, the mounting position of the horizontal plate 5 in the vertical direction can be adjusted.

(3) How to attach the reaction plate (first step)
Figure) Reaction plate 2 is placed on horizontal plate 5.
is mounted, a mounting bolt 53 is passed through the elongated hole and the mounting hole, and the bolt 53 is tightened and fixed with a nut 54.

Since long holes are opened on both edges of the reaction plate 2, the reaction plate 2
The mounting position can be adjusted by sliding it across the track.

Further, in order to attach the reaction plate 2 on the pedestal plate 5, it is also possible to use a spring clamp 8 as shown in FIG.

That is, the spring clamp 8 includes a straight portion 81 that grips the leg portion 21 of the reaction plate 2;
It consists of a curved spring part 82 on the extension of the straight part 81 for imparting elasticity to the straight part 81, and is formed by molding a steel plate or the like.

A hole is formed through the plate surface of the straight portion 81.

And the leg portion 21 of the reaction plate 2
The straight portion 81 of the spring clamp 8 is mounted on the edge of the spring clamp 8, and is attached to the mount plate 5 using bolts 53 or the like.

Therefore, the range where the leg portion 21 and the straight portion 81 overlap becomes the adjustment range.

[E] Other Embodiments In addition to the embodiments described above, it is also possible to adopt technical means for supporting the reaction plate 2 as shown in FIG. 4.

That is, this is a method of laying using a support member 9 made of H-shaped steel or the like having a surface narrower than the transverse width of the reaction plate 2.

After the lower surface of the support member 9 is mounted on the pedestal plate 3 attached to the sleeper 6, it is fixed to the sleeper 6 with, for example, an anchor bolt 91, a U bolt, a screw nail, a through bolt, or the like.

Furthermore, the reaction plate 2 is mounted on the upper surface of the support member 9 and welded 13, and furthermore, the support member 9
In this method, the bottom surface of the base plate 3 is fixed to the pedestal plate 3 by welding 14.

[F] Effects Since the present invention is as explained above, the following effects can be expected.

(1) As shown by the dashed line in Fig. 2, according to the conventional mounting method, the wing plate B of the reaction plate protrudes outward, so the distance between the inside of the rail R and the mounting part of the reaction plate 2 is becomes L1.

On the other hand, when the support material 1 of the present invention is adopted, the installation width of the bottom surface of the support material 1 that supports the reaction plate 2 is smaller than the transverse width of the reaction plate 2. The distance L2 to the end of the attachment portion of No. 2 can be made much smaller than the conventional L1.

Therefore, collision between the bottom of the support member 1 and the lower part of the rail R can be prevented, and the reaction plate can be laid as close as possible to the rail side.

As a result, the interval at which the reaction plates are not installed can be shortened, and good running stability can be ensured.

(2) The reaction plate was installed so that its movement in the transverse direction of the track and the installation height in the vertical direction could be adjusted.

Therefore, if the gap between the reaction plate and the linear motor needs to be adjusted due to wear of the rails or aging of the wooden sleepers, the gap between the reaction plate and the linear motor can be adjusted with a simple operation.

As a result, a good gap can always be maintained between the reaction plate and the linear motor, and the rail can be used up to its serviceable limit by adjusting the gap.

(3) Reaction plates can be installed not only on concrete sleepers but also on conventional wooden sleepers.

Therefore, the track of the conventional line can be effectively utilized and it is economical.

(4) The lower part of the reaction plate can be supported without being blocked.

Therefore, the heat dissipation effect of the reaction plate is improved.

(5) If double nuts, etc. are used for the bolts for attaching the reaction plate or for horizontally mounting the pedestal plate,
Can adequately handle vibrations while driving.
