Description

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

Recently, among the traveling methods using linear motors, a traveling method that utilizes the attractive force of magnetic force has been developed.

In this traveling method, a vehicle equipped with a linear motor (-next side) is mounted on the rail through wheels, and a conductive plate made of copper, aluminum, etc. is mounted on the rail side, facing the linear motor along the direction of travel. A reaction plate (secondary side) is placed on the ground, and by creating an attractive force due to magnetic force between the reaction plate fixed to the rail side on the ground and the linear motor, the vehicle moves forward while being actively pressed against the rail side. This method makes it possible to significantly improve stability.

By the way, when installing the reaction plate, it is important to pay attention to the position of the reaction plate, as it must be installed with a certain gap maintained between the linear motor mounted on the vehicle and the reaction plate.

However, at railroad crossings and other places where work vehicles cross the tracks, the conductive plates of the reaction plates, which are made of relatively soft copper or aluminum, are gradually scraped off and worn out.

As a result, a gap between the reaction plate and the linear motor opens, which may impede smooth running.

The present invention was made to solve such problems.
The purpose of the present invention is to provide a structure for a reaction plate of a magnetic attraction type traveling vehicle, which can always maintain a constant gap between the reaction plate and a linear motor even at a railroad crossing or where other work vehicles cross the track. .

The structure of the reaction plate of the present invention will be explained below based on the drawings.

[A] Reaction plate (Fig. 1) As the reaction plate 5, there is an action plate 51 for general track used for general track I that is not crossed by other vehicles.
A cross-trajectory reaction plate 52 is used for a cross-trajectory O that is frequently crossed by other vehicles, such as at railroad crossings.

The reaction plate 5 consists of a conductive plate 5a serving as a conductive magnetic surface and a base material 5b on which the conductive plate 5a is placed.

The base material 5b and the conductive plate 5a are bonded using adhesive,
There are coating methods such as a rolling method, an explosive bonding method, and a riveting method.

In addition, as the base material 5a, in addition to a single plate that is placed directly on a sleeper dedicated to the reaction plate that has a mounting stand,
When using conventional wooden sleepers, conductive plates 5 are used to set the gap with the linear motor to a predetermined size.
A trapezoidal base material 5b having leg portions 5C may be used at both ends of the surface on which a is placed. (FIG. 2) It is also conceivable to support the reaction plate 5 by fixing H-beams or the like in the longitudinal direction to the lower surfaces of both sides of the reaction plate 5, which is a single plate made of the conductive plate 5a and the base material 5b.

<Action plate for general track> The action plate 51 for general track is a reaction plate in which a conductive plate 5a such as a copper plate, an aluminum plate, a duralumin plate, etc. is bonded to a base material 5b by the method described above. .

Reaction plate for transverse track> The reaction plate 52 for transverse track does not use a copper plate, an aluminum plate, a duralumin plate, etc., which are prone to wear.

Instead, a steel plate with high abrasion resistance, such as a check steel plate, which has greater abrasion resistance than copper or aluminum and is electrically conductive, is used as the conductive plate 5a.

[Loco sleeper] The sleeper 2 is a prismatic body made of concrete or the like, and in the center of the sleeper 2 there is a mounting table 21 on which the reaction plate 5 is placed, and on both sides of the mounting table 21 there are known rails. 11 is formed. (3rd
(Figure) Even if you have a conventional wooden sleeper, the same effect can be achieved by making the base material 5b of the reaction plate 5 into the above trapezoidal shape, or by supporting the plate reaction plate 5 using H-beam steel or the like. The reaction plate 5 can be attached to.

[Box Spring Clamp (FIG. 3)] The spring clamp 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 clamp 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 heel 43 is more securely fastened.

Next, a method for attaching the reaction plate of the present invention will be explained.

[A] Laying sleepers Sleepers 2 made of concrete or the like are arranged and fixed at regular intervals on the track.

[Explanation] To attach the reaction plate, the rails 11 are successively arranged on the installation base 22 of each sleeper 2 and fixed using a known rail fixing tool.

Next, a reaction plate 5 is mounted on each sleeper 2.

At this time, a cross track reaction plate 52 is installed on the cross track 0 section where other vehicles cross, such as at a railroad crossing, and a general track action plate 51 is installed on the general track I.
Set up.

Then, the spring clamp 4 is attached to each mounting table 2 with the jaw 42 of the spring clamp 4 in contact with the upper surface of the reaction plate 5.
1, and the reaction plate 5 is fixed to the sleeper 2 by inserting the bolt 6 into the elongated hole 44 and screwing it into a buried insert.

When using ffH type steel or the like as a support material for the reaction plate 5, it is conceivable to fix the sleeper 2 and the H type steel with the above-mentioned spring clamp 4, and then mount the reaction plate 5 thereon.

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

Kui> At railroad crossings and other places where work vehicles cross the tracks, we have installed reaction plates made of checked steel plates with high wear resistance as conductive plates.

As a result, the conductive plate is less worn, and the gap between the reaction plate and the linear motor can be kept constant for a long time, allowing for good running.

〉Reaction plates made of highly wear-resistant steel plates can be installed on the transverse track regardless of the shape of the sleepers or the method of supporting the reaction plates.

Therefore, regardless of the type of track, if a cross-track reaction plate is installed on the cross-track, running of the linear motor car will not be hindered.
