Description

[Detailed Description of the Invention] The present invention relates to an attachment device for a reaction plate of a magnetic attraction type traveling vehicle that travels by utilizing magnetic attraction force.

Vehicles that levitate and travel using magnetic repulsion have had problems with stability while traveling.

To solve this problem, a traveling method that utilizes magnetic attraction has recently been developed.

In other words, this new traveling method involves mounting a vehicle equipped with a linear motor (primary side) on the rail through wheels, and a reaction plate (secondary side) mounted on the rail side facing the linear motor along the direction of travel. A system in which the vehicle is moved forward while being actively pressed against the rail side by generating magnetic attraction between the reaction plate fixed to the rail side on the ground and the linear motor. This made it possible to significantly improve stability.

By the way, reaction plates are generally not made up of one continuous plate but are made up of a single plate, and these single plates are arranged continuously on the sleeper in the direction of travel.

To attach a reaction plate to a sleeper, place one end of a fixture made of a single rectangular plate on the top surface of the concrete sleeper that will be in contact with the reaction plate, and then The structure is such that the reaction plate is fixed by passing bolts through the plate surface of the fixing device and screwing them into the sleeper.

However, in curved sections and intersections, the screwing positions of the bolts and the bolt holes opened on the sleeper side do not necessarily match.

If the screwing position of a bolt is misaligned even in one place on a single reaction plate, there is no means to adjust the screwing position of the bolt, so it becomes impossible to attach a fixing device to that spot, and the reaction plate cannot be installed. Becomes incomplete.

Moreover, it is difficult for the conventional reaction plate fixing structure to elastically hold the reaction plate.

This invention was made to improve the above points, and is a magnetic suction type that can adjust the mounting position of the fixture even at curved parts and intersections of the reaction plate, and can elastically hold the reaction plate. An object of the present invention is to provide a mounting device for a reaction plate of a running vehicle.

Embodiments of the present invention will be described below based on the drawings.

[A] Overall Description FIG. 1 shows the entire mounting device of the present invention, and the mounting device 1 of the present invention is composed of a sleeper 2 in which an insert 3 is embedded and a spring clip 4.

[B] Sleepers Sleepers 2 are prismatic bodies made of concrete,
At the center of this sleeper 2, two mounting tables 21 for mounting the reaction plates 5 are formed, and at both hem portions of the mounting tables 21, a laying table 22 for fixing a known rail 11 is formed.

An insert 3 having a thread carved on the inside is buried in the top surface of the mounting table 22.

It should be noted that the sleeper 2 may also have a structure in which two mounting tables 21 are connected into one.

[C] Spring Clip As shown in FIGS. 2 and 3, the spring clip 4 has a jaw 42 formed at one end of a rectangular base plate 41, and a heel 43 protruding from the lower surface of the other end of the base plate 41.

A long hole 44 is formed in the center of the substrate 41.

The reason why the heel 43 is provided protrudingly from the other end of the base plate 41 is that when the spring clip 4 is tightened with the bolt 6, a space is formed on the lower surface so that the base plate 41 is bent and the spring clip 4 is tightened more reliably.

[D] Reaction Plate The reaction plate 2 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.

Next, a method of using the mounting device of the present invention will be explained.

[B] Laying of sleepers The sleepers 2 with the inserts 3 buried therein are arranged and fixed at regular intervals on the track bed.

[B] Attachment of Reaction Plate The rails 11 are arranged continuously on the installation base 22 of each sleeper 2 and fixed with a known anti-creeper or the like.

Next, the reaction plate 5 is mounted on each mounting table 21.

At this time, the joints of each reaction plate 5 are positioned on the sleepers 2, and at the same time, gaps are provided between the joints to accommodate thermal expansion.

Then, the spring clip 4 is placed on each mounting table 21 with the jaws 42 of the spring clip 4 in contact with the upper surface of the plate 5, and the bolt 6 is inserted into the elongated hole 44 and screwed into the insert 3.

As a result, a gap is created between the base 41 of the spring clip 4 other than the heel 43 and the mounting table 21.

This gap gives elasticity to the spring clip, so that the plate 5 can be firmly pressed against the mounting table 21 and fixed.

[C] Spring clip adjustment The fixed position of the reaction plate gradually shifts at curved sections or intersections.

In the device of the present invention, since the elongated hole 44 is formed in the spring clip 4, the insert 3 buried in the mounting table 21 can be
The mounting position can be adjusted by sliding the spring clip 4 along the elongated hole 44 to a position that corresponds to the center of the spring clip.

That is, one of the features of the device of the present invention is that the position at which the plate 5 is to be fixed can be adjusted using the elongated hole 44 of the spring clip 4.

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

<B> Since the spring clip has an elongated hole in its base, the attachment position of the spring clip can be easily adjusted by sliding the spring clip in the direction of the elongated hole.

<B> A heel is provided on the spring clip, and a space is provided on the underside of the heel to provide elasticity.

Therefore, the reaction plate can be securely fixed by the spring effect.
