Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaction plate mounting device for a magnetic attraction type vehicle that travels by utilizing magnetic attraction force.

Recently, in a system of traveling using a linear motor, a traveling method that utilizes the attractive force of magnetic force has been developed.

In other words, this new traveling method mounts a vehicle equipped with a linear motor (-next side) on the rail via wheels, and on the other hand,
A reaction plate (secondary side) is placed on the rail side facing the linear motor along the direction of travel, and an attractive force is generated by magnetic force between the reaction plate fixed to the rail side on the ground and the linear motor. This method allows the vehicle to move forward while being actively pushed against the rail, making it possible to significantly improve stability.

By the way, the reaction plate generally does not consist of one continuous plate but a single plate, and this single plate is arranged continuously on the sleeper in the direction of travel.

The sleepers to which the reaction plate was attached were made and used specifically for the reaction plate.

Its structure consists of two mounting stands for placing the reaction plate U in the center of a concrete prismatic body, and a mounting stand for fixing known rails at both hems of the mounting stand, and the top of the mounting stand. The surface has an insert with a thread carved on the inside.

For example, one end of a fixing device made of a single rectangular plate is positioned on the top surface of the reaction plate, and a bolt is passed through the plate surface of the fixing device. The structure is such that the reaction plate is fixed by screwing into the joint.

However, manufacturing a special guide for attaching a reaction plate like this requires a great deal of expense.

Therefore, if reaction plates could be attached to conventional wooden sleepers, this would be a double advantage as it would reduce costs and reuse wooden sleepers.

The present invention has been made in view of the above points, and an object of the present invention is to provide a method for attaching a reaction plate to a magnetic attraction type traveling vehicle, which fixes the reaction plate to a wooden sleeper.

Embodiments of the present invention will be described below based on the drawings. First, each member used in the embodiments will be explained.

[A] Overall description FIG. 1 shows the entire installation of a reaction plate by the method of the present invention.

R is a rail, 1 is a reaction plate, 2 is a conventional wooden prismatic sleeper, and 3 is a fastening clip.

[Explanation] Reaction plate The reaction plate 1 is a plate body formed by bonding, explosive bonding, riveting, rolling, etc., a copper plate, aluminum plate, duralumin plate, etc. to a base material made of a strip-shaped steel plate or the like.

Both legs in the longitudinal direction of the reaction plate 1 are extended members to form leg parts 11, and a flange 12 extending outward and parallel to the plate surface is formed at the tip of the leg part 11.

[C] Fastening clip The fastening clip 3 is a plate longer than the width of the sleeper 2 in the installation direction, which will be described later, and has bolt holes 31 at both ends in the longitudinal direction.
will be established.

The reaction plate 1 is adjacent to the bolt hole 31.
A jaw portion 32 is provided to hold down the flange 12 from above.

Two bolt holes 31 are configured so that U-bolts 33 that embrace and fasten the sleeper 2 from below are located.

[2] Sleepers Sleepers 2 are conventional wooden sleepers.

Next, we will explain how to attach reaction plates to wooden sleepers using each of the above devices.

[B] Laying sleepers Sleepers 2 are arranged and fixed at regular intervals on the soft body.

[Explanation] Attaching the reaction plate The rails 11 are arranged in succession on each sleeper 2 and fixed using a known rail fixing device.

Next, the reaction plate 1 is mounted on the center part of the sleeper 2 to which the rail R is fixed.

At this time, the joint of each reaction plate 1 is the sleeper 2.
In some cases, they are placed on top, and at the same time, a gap is provided between the seams to accommodate thermal expansion.

Once the position of rail R1 rear axicon plate 1 is determined,
A hole is drilled in the lower part of the left and right seven flange 12 of the reaction plate 1, and the U-bolt 33 is inserted therein to enclose the sleeper 2.

Next, after inserting the tip of the U bolt 33 holding the sleeper into the bolt hole 31 of the fastening clip 3, place the jaw 32 on the 7 lange 12 of the reaction play 1-1 and tighten the bolt to complete the fastening. do.

[C] Other Embodiment 1 (FIG. 3) In the above embodiment, a means of enclosing the sleepers 2 with U-bolts was adopted for fastening, but it is of course possible to adopt the following method.

That is, using a fastening clip 3 that is the same width as the sleeper 2 and has a bolt hole 31 in the center, etc., insert a screw N with a head larger than the diameter of the bolt hole 31 through the bolt hole 31 into the wooden sleeper. 2 and tighten.

[2] Other Embodiment 2 (Fig. 4) As another fastening means, a fastening clip 3 having the same width as the sleeper 2 and having a bolt hole 31 in the central part etc. is used to connect the wooden sleeper 2. At the top, a through bolt hole 21 is opened at a location slightly away from the position where the flange 12 of the reaction plate 1 rests, and a bolt hole 31 of the fastening clip 3 is opened.
Another possible method is to pass the bolt B through the through-bolt hole 21 of the sleeper and fasten it.

[E] Other Embodiment 3 (FIG. 5) It is also conceivable to adopt the following means as the fastening means.

That is, on the wooden sleeper 2, there is a position slightly away from the position where the flange 12 of the reaction plate 1 is placed.
An enlarged hole 22 whose inside is enlarged is bored.

Then, use a fastening clip wrap 3 that is approximately the same width as the sleeper 2 and has a bolt hole 31 in the center, etc., and insert the anchor bolt A, whose tip expands when tightened, from the bolt hole 31 into the expanded hole 22. The reaction plate 1 is fastened to the sleeper 2 by enlarging its tip.

[F] Other Embodiment 4 (FIG. 6) In the above embodiment, a plate having no elasticity was used as the fastening clip 3, but it is also possible to use spring steel for the fastening clip 3.

That is, after placing the end of the fastening clip 3 made of spring steel on the upper surface of the flange 12 of the reaction plate 1, the fastening clip 3 is fastened with bolts B or the like.

In this case, since the fastening clip 3 has elasticity, more reliable fastening can be performed.

Since the present invention is as explained above, the following effects can be expected.

There is no need to use concrete sleepers specifically designed for reaction plates, and reaction plates can be easily attached to conventional wooden sleepers.

Therefore, it becomes possible to install the reaction plate economically.

Wooden sleepers are used at track points and rail joints, and the installation method of the present invention is extremely useful for these areas.

Kuha> Sleepers and reaction plates can be easily replaced.

<2> The flange portion of the reaction plate was held down by the jaws of a fastening clip, and the fastening clip was fastened directly to a wooden sleeper using bolts or the like.

Therefore, it has become possible to fasten the bolts with a pull-out resistance that can withstand the suction force of the linear motor.

When using spring steel as the fastening clip, since the fastening clip 3 has elasticity, more reliable fastening can be performed.
