Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing a reaction plate for a linear motor car 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) Since there is no easy and suitable installation technique for attaching reaction plates to wooden sleepers on conventional lines, magnetic attraction type running tracks must be newly constructed.

Therefore, it is difficult and uneconomical to utilize conventional railway tracks with wooden sleepers.

(2) As shown in Figures 7 and 8, at the branching part (point part) of the trajectory, the reaction plate A
need to be laid with continuity.

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 becomes, which is a problem in running.

The present invention was created in view of the current situation,
The purpose of the present invention is to provide a method for fixing a reaction plate using a magnetic attraction method, which allows the reaction plate to approach the rail as close as possible at a branching 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 1 is a plate formed by covering the upper surface of a strip-shaped iron plate 11 with a conductive plate 12.

The conductive plate 12 is made of a strip-shaped copper plate, an aluminum plate, a duralumin plate, etc. by gluing, rolling, or
Formed by riveting or explosive bonding.

(2) Support material The support material 2 is a member on which the reaction plate 1 is mounted and supported on the sleeper 3.

That is, the supporting member 2 is formed into an H-shaped cross section by connecting, for example, two parallel plates, an upper plate 21 and a lower plate 22, with a vertical plate 23.

The lower plate 22 of the support member 2 is formed to have a narrower width than the transverse width L of the reaction plate 1 so that the reaction plate 1 can approach the rail R side.

(3) Base plate The base plate 4 is a rigid plate for installing the support member 2 on the sleeper 3 while ensuring stability, and is made of, for example, a steel plate.

This pedestal plate 4 is used by being integrally fixed to the upper surface of the sleeper 3 by various methods as will be described later.

In addition, the lower plate 22 of the support member 2 can be directly connected to the sleeper 3.
In the case where the base plate 4 is fixed to the base plate 4, the pedestal plate 4 can be omitted.

Next, a method of installing reaction plates at point locations on the rail will be explained.

(1) Fixing the reaction plate and support material (Fig. 2) At the point, the reaction plate 1
It is necessary to lay the front part of the rail as close as possible to the rail R that intersects the track.

Therefore, in advance, attach the upper plate 21 of the support material 2 to the iron plate 11 on the back side of the reaction plate 1.
are fixed by welding 13 to integrate the support member 2 and the reaction plate 1.

(2) Laying of pedestal plates On the other hand, pedestal plates 4 made of a single steel plate or the like are mounted on the top surface of each sleeper 3 laid at equal intervals.

The base plate 4 is a member intended to improve the stability of the support member 2.

(3) Fixing to a sleeper For example, in the case of a wooden sleeper 3, the base plate 4 in which the reaction plate 1 and the support member 2 are integrated is fixed with screws 5 or the like.

One of the features of the present invention is that the support member 2 is arranged and attached at any position on the axis of the sleeper in the longitudinal direction (orthogonal direction to the track).

(4) On-site welding of the support material The lower plate 22 of the support material 2 is mounted on the pedestal plate 4 in contact with it, and both 22 and 4 are welded 14 to be integrated.

Furthermore, it is also possible to fix the pedestal plate 4 to the sleeper 3 after welding 14 the pedestal plate 4 to the lower plate 22 of the support member 2 which is integrated with the reaction plate 1.

(5) Other Examples 1 <A> Method of fixing with U-bolts (Fig. 3) As another method of fixing the support material 2 to the sleepers 3, U-bolts 7 can be adopted.

That is, the U bolt 7 is inserted under the sleeper 3 and the free end of the U bolt 7 is passed through the pedestal plate 4 or the lower plate 22 and fastened with a nut.
This is a method of fixing the pedestal plate 4 or the lower plate 22 by pressing it from above using a clamping member made of a rectangular plate.

According to this method, both wooden and concrete sleepers can be fixed.

<B> Method of fixing with through bolts (Figure 4) Alternatively, it is also possible to use a method in which the through bolts 8 are passed through the sleepers 3 and the support material 2 or the lower plate 22 to secure the support material 2. be.

<C> Method of fixing with anchor bolts (No. 5)
(Figure) In this method, an anchor hole 91 is opened in the sleeper 3, and an anchor bolt 9 whose resistor 92 expands when fastened is inserted into the anchor hole 91 and fixed.

(6) Other Embodiments 2 (FIG. 6) In addition to the embodiments described above, it is also possible to configure the attachment position of the reaction plate 1 to be adjustable in height.

That is, for example, reaction plate 1
One end of the bolt 13 facing in the transverse direction of the track is buried and suspended in the lower surface side of the iron plate 11.

Then, the free ends of both bolts 13 with support nuts 14 screwed onto their peripheral surfaces are passed through the upper plate 21 of the support member 2, and the reaction plate 1 is locked to the support member 2 via the support nuts 14.

As a result, by rotating the support nut 14, the screwing position of the bolt 13 is moved, and the height of the reaction plate 1 can be adjusted.

[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. 9, 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 1 is becomes L1.

On the other hand, when the support material 2 of the present invention is adopted, the installation width of the bottom surface of the support material 1 that supports the reaction plate 1 is smaller than the cross-sectional width of the reaction plate 1. 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 2 and the lower part of the rail R can be prevented, and the reaction plate 1 can be laid as close as possible to the rail R 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) If the reaction plate is installed so that its height can be adjusted in the vertical direction, the gap between the reaction plate and the linear motor may need to be corrected due to wear of the rails or aging of the wooden sleepers. If so, it 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.
