Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of coupling reaction plates for a linear motor car that runs using magnetic attraction.

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

In this method, a vehicle with a linear motor (primary side) is mounted on the rail via the vehicle, and a reaction plate (secondary side) is placed on the rail side facing the linear motor along the traveling direction. This method generates an attractive force due to the magnetic force between the two, and moves the vehicle forward while actively pressing it against the rail.

This combination of wheels and rails improves stability and has the advantage of being able to run quietly even on steep slopes.

[B] Problems to be solved by the present invention Since the length of one reaction plate and the spacing between the sleepers do not necessarily match, the connecting part of the reaction plate is located between one sleeper and the next sleeper. It may be located in

It is easy to connect two reaction plates above a sleeper, but when connecting them between one sleeper and the next sleeper, the two will be connected in the air. Strong and reliable bonding methods and means are required.

[C] Purpose of the present invention The present invention was made in order to solve the above-mentioned problems, and provides a coupling method that enables strong, reliable, and easy coupling when coupling reaction plates in the air. The purpose is to provide the following.

[d] Overall configuration <1> Overall configuration As shown in Figure 1, there are two groups of sleepers and one rail.
and the reaction plate 5 is fixed.

Then, the ends of the reaction plates 5 located between one sleeper and the next sleeper are connected by the joining method of the present invention.

<2> Structure of sleeper Sleeper 2 is a prismatic body made of concrete.

Two mounting tables 21 for mounting reaction plates 5 are protrudingly provided in the center of this sleeper 2.

Moreover, rail laying bases 22 for fixing the public rails 1 are formed at both hem portions of the mounting base 21.

An insert 3 having a thread carved on the inside is buried in the top surface of the reaction plate mounting table 21.

In addition, the sleeper 2 has two rail laying stands 22.
It is also possible to adopt a structure in which the two are formed continuously and integrally.

<3> Reaction Plate The reaction plate 5 is a plate formed by bonding, explosive bonding, riveting, or rolling a conductive plate 52 made of a copper plate, aluminum plate, duralumin plate, etc. to a base body 51 made of a strip-shaped steel plate or the like. It is the body.

The base material 51 is formed with wing parts 53 projecting out on both sides thereof, and is fixed to the sleeper 2 via the wing parts 53 with clips 23 or the like.

Both ends of the reaction plate 5 are configured to go in and out symmetrically.

For example, a shelf plate 54 is provided projecting below the end of the reaction plate 5, while an eaves plate 55 is provided projecting upward from the other end of the reaction plate 5.

Therefore, by butting the ends of the two reaction plates together, the eaves plate 55 will be positioned exactly on top of the shelf plate 54.

In short, the shapes of the shelf board 54 and the eave board 55 may be stepped, or may be a combination of relative shapes, such as providing the shelf board 54 in the center and providing a storage groove on the corresponding eave board 55 side. It's good to have.

Then, a single hole 54a is provided on the shelf board 54 side, and a screw hole 55a is provided on the eave board 55 side, at relatively corresponding positions when the shelf board 54 and the eaves board 55 are overlapped.

<4> Backing Plate The backing plate 6 is simply a plate made of a steel material cut into squares, and has holes 54a and screw holes 55a formed in the shelf board 54 and the eaves board 54, respectively.
Open a single hole 6a.

The width of the backing plate 6, that is, the width in the direction across the rail 1, is configured to be narrower than the interval between the mounting tables 21 of the sleepers 2.

In this way, even if a part of the backing plate 6 falls on the position of the sleeper 2, there will be no problem with the installation.

Further, it is also possible to employ elongated holes as the single holes 54a and 6a.

<5> Connection method A case will be described in which one reaction plate 5 and an adjacent reaction plate 5 are connected in the air between the sleepers 2.

The ends of the two reaction plates are abutted and tightly overlapped so that the eaves plate 55 of the adjacent reaction plate 5 is positioned above the shelf plate 54 of one reaction plate 5.

And the single hole 54a of the shelf board 54 and the eave board 55,
The screw holes 55a are overlapped, and a backing plate 6 is placed on the underside of the screw holes 55a.
position.

Then, one bolt 61 is aligned with the single hole 54a opened in the shelf board 54 and the eaves board 55, the screw hole 55a, and the single hole 6a of the backing plate 6 on a vertical line.
Fix the three plates by screwing them together.

In this case, the length of the bolt 61 is set to such a length that the free end of the bolt 61 is not exposed above the eaves plate 55 when the entire length of the bolt 61 is screwed in.

As described above, the connection between the two reaction plates is completed by the simple operation.

(Other Embodiments) In some cases, a screw hole 55a and single holes 54a, 6a are opened in both reaction plates 5 to be joined at the site to perform the joining.

That is, the shelf board 5 of both reaction plates 5
4 and the eaves plate 55, a through hole is made with a drilling machine, a screw is carved in the hole on the eaves plate 55 side, and the bolts 61 are used to connect the two.

This is suitable for joining the reaction plates 5 at curved locations where it is difficult to align the hole positions during joining.

[E] Effects Since the connection method of the present invention is as described above, the following effects can be expected.

<A> This is a method of connecting reaction plates by connecting plates formed at both ends of the reaction plates that move in and out relatively with bolts.

Therefore, even if the joint between the two reaction plates is located between the sleepers and there is no support from below, the two reaction plates can be securely fixed.

Therefore, even if a suction force is applied to the linear motor side, the end of the reaction plate will not float due to the suction force.

<B> Attach the ends of the two reaction plates,
Connection is completed by simply connecting with bolts.

Therefore, even long work can be completed efficiently.

<C> Since the bottom plate is used to connect the reaction plate, the connection is strong and the reaction plate can be fixed more reliably.
