Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The disclosed technology is a guideline for a road surface side of an iron rail traveling linear motor car that can travel freely on a road surface with a slight set height. It belongs to the technical field of polymer construction of the secondary plate.

<Summary of Summary> Therefore, the invention of the present application is directed to a pair of mild steel plates of a secondary side plate of a linear rail car of an iron rail running type, a joint surface having different concave and convex portions of different materials such as an aluminum plate. It is an invention relating to a polymer structure in which the metal structure is closely adhered and tightened in the longitudinal direction so that there is no mechanical displacement or peeling through, and in particular, a row along the longitudinal direction on the joint surface of the material of one metal body. -Shaped underhang portion has a concave portion, and the convex portion of the overhang portion similarly formed along the longitudinal direction on the bonding surface of the material of the other metal body is formed by press molding or the like to form another thin film. The invention relates to a polymer structure of a secondary side plate on the road surface side of a linear motor car that is tightly adhered and firmly integrally fitted to all corners of a recess via a body.

<Prior Art> As is well known, transportation is remarkably useful. Among them, for example, transportation means such as railroad is capable of high-speed and smooth mass transportation on time schedule. It occupies a very important position separately.

However, as the speed of information transmission becomes faster and the speed of railway transportation becomes higher, vibration and noise cannot be ignored due to the close-up of pollution problems and environmental harmony problems. From a number of advantages such as quietness and vibration-free from the viewpoint of increase in construction amount and cost increase due to excavation of large-scale ground, and the fact that the cross-section of a tunnel or the like can be downsized, for example, JP-A-57-91663. Inventions and developments No. 49-15611 Inventions and developments No. 59-282
The so-called linear motor car of the railway running type as disclosed in the invention of No. 80, etc. has come to the spotlight and has already been put to practical use in some cities and the like.

Thus, the structure of the secondary side plate on the road surface side, which generates an eddy current as a driving force by generating an eddy current on the primary side of the seed rail running linear motor car, has good electrical conductivity from the functional aspect. And a material having a high magnetic permeability and electromagnetic characteristics are required. Moreover, since it is a reaction force support that causes a considerably strong driving force, it can sufficiently withstand shearing force and peeling force over time. It must be a material that has mechanical properties, and for materials such as metals that have these various properties, a single material cannot be obtained by the current technology, and therefore electrical A polymer obtained by closely bonding metal bodies of different materials having good conductivity and high magnetic permeability to each other is used as a secondary side plate on the road surface side.

That is, for example, in a secondary side plate 1 as shown in FIG. 10 (a cross-sectional view of the secondary side plate), a mild steel plate is used as the lower lower plate 2 having high magnetic permeability, while an electric From the upper aluminum plate 3 side by countersunk bolts 4, 4, ... By mechanically processing an aluminum plate 3 as an upper upper plate having good electrical conductivity so as to sandwich the mild steel plate 2 by press molding. As a lower lower plate such as a mechanically integrated mode (for example, Japanese Patent Laid-Open No. 59-201671, etc.) or a secondary side plate 1'shown in FIG. 11 (a sectional view of the secondary side plate). A mode in which an aluminum plate 3 as an upper upper plate is adhered to the mild steel plate 2 as a clad by an explosive deposition 5 is adopted.

However, as described above, since the secondary side plates 1 and 1'have to have a supporting function against the reaction force of the strong driving force that repeatedly acts at high frequency, the shearing force in the longitudinal and lateral directions is increased. Therefore, there is a condition that a large resistance force is required to be provided, and that a resistance force against the vertical peeling force must be sufficiently maintained.

In particular, in subways, etc., it is necessary to resist the thermal behavior and the addition of peeling force against temperature differences and mechanical vibrations, and the secondary side plate 1 as shown in FIG. 10 and the secondary side plate as shown in FIG. The plate 1'has the drawback that it cannot be provided with sufficient drag over time.

In particular, in the mode of the secondary side plate 1 formed by press molding as shown in FIG. 10, there is a drawback that mechanical adhesion force and tightening force tend to loosen over time, and as shown in FIG. The secondary side plate 1'has the disadvantage that it is economically very expensive to manufacture and does not match the cost.

Further, in a subway using a tunnel, for example, a subway near the coast, the environment is remarkably bad due to corrosion of the secondary side plate due to humidity and exposure to severe conditions such as flooding, and the mild steel plate 2 on one side is There is a problem that corrosion may occur on the joint surface between the aluminum plate 3 on the other side and the aluminum plate 3, and the function as the secondary side plate may not be maintained over time.

Then, in order to deal with this, for example, in Japanese Utility Model Publication No. Sho 49-1156.
In the secondary side plate as disclosed in the invention of the publication No. 11, a wedge-shaped groove having an underhang portion in the lateral direction (width direction) is formed on one of the magnetic metal plates, and the upper side aluminum plate is made of aluminum. Mold the upper plate 3 by die casting,
Similarly, there is a technique in which a protrusion of the overhang portion in the lateral direction (width direction) is engaged with the wedge-shaped groove to be coupled.

However, in the road side reaction plate of such a linear motor car, one lower plate 2 and the other upper plate 3 are tightly connected to each other through the engagement of the overhang portion and the underhang portion in the lateral direction (width direction). Therefore, due to vibration and thermal behavior as described above,
There is a disadvantage that vertical peeling easily occurs over time.

Further, such a negative point is also the same in the device of Japanese Utility Model Publication No. 59-28280.

<Object of the Invention> The object of the invention of the present application is a technical problem to be solved such as a metal polymer of the secondary plate on the road surface side of the iron rail traveling linear motor car based on the above-mentioned prior art,
Even if the vibration force that repeatedly acts, the strong shear stress, the intense thermal behavior, etc. adheres to the dissimilar metals, the tightened state can be maintained without causing slippage or peeling, and at a low cost, it can be manufactured. It is intended to provide an excellent polymer structure of the secondary side plate on the road surface side of the linear motor car, which is useful for the field of railway technology in the transportation industry and the like, with almost no change over time.

<Means and Actions for Solving the Problem> In order to solve the above-mentioned problems, the structure of the invention of the present application, which is based on the above-mentioned object, is based on the above-mentioned object. In the polymer structure of the secondary side plate of one of the above, the downward convex of the overhang portion along the longitudinal direction of the running direction of the linear motor car is formed on the joint surface of one of the materials such as the metal body having good conductivity such as the aluminum plate. Part of the metal body such as a mild steel plate having a high magnetic permeability on the other side is formed with an upward concave portion of the underhang portion along the corresponding longitudinal direction so that the concave portion and the convex portion are formed at both corners. The projections are tightly engaged with the recesses in all the corners by means such as press-fitting with a roller, press-fitting with a roller or the like to have a tightened state. Corrosion-proof function Sufficient against vibration force, strong shearing force and peeling force due to thermal behavior that are repeatedly applied in a tightly fastened state by interposing another thin film metal material having It is a technical measure that makes it possible to withstand.

<Embodiment> An embodiment of the invention of this application will be described below with reference to FIGS. 10 and 11 will be described using the same reference numerals.

The illustrated embodiment is similar to the secondary side plates 1 and 1 ′ on the road surface side of the linear rail running type linear motor car shown in FIGS. 10 and 11, and FIG. In the embodiment shown in FIG. 11), reference numeral 111 denotes a roadside secondary plate of the linear motor car that forms the center of the gist of the invention of this application, and has a high transparency like the conventional embodiment shown in FIGS. A lower straight mild steel plate 2 as a metal body of a material having magnetic susceptibility and a highly conductive aluminum plate 3 as a metal body of the other material on the upper side thereof are mechanically coupled to each other through the means described below. In the longitudinal joint surface 11 of the two running linear motor cars, downward taper-shaped overhang portions 6, 6'are formed on the upper joint surface of the mild steel plate 2 side of the linear motor car. A recess formed along the longitudinal direction of the running direction 7 are formed on the side of the mild steel plate 2, and a predetermined pattern is formed in the arrangement in the cross-sectional direction according to the design.

On the other hand, on the lower joint surface of the aluminum plate 3 side, a convex portion 9 forming an underhang portion 8 corresponding to the concave portion 7 of the mild steel plate 2 along the longitudinal direction is provided along the longitudinal direction of the running direction of the linear motor car. Formed by the concave portion 7 and the convex portion 9
Means that during casting, both are mechanically tightened in a close contact state by plastic pressure bonding by a predetermined means such as press fitting with a roller, so that the polymer 111 is integrated with an extremely high bonding force. , It has a sufficient resistance to the shearing force not only in the longitudinal direction but also in the lateral direction. (In the longitudinal direction, a large frictional force can be formed in the distance to sufficiently resist the shearing force. Are underhang parts 8 and overhang parts 6, 6 '.
Keeps enough drag. ), And has sufficient resistance to the peeling force due to thermal behavior due to temperature changes and the like.

In the above configuration, when a linear motor car (not shown) travels in the longitudinal direction on the secondary plate 111 on the road side secondary plate 111 of the laid linear motor car at a predetermined flying height, An eddy current is formed and driven through the aluminum plate 3, and a supporting force is obtained with high permeability by the mild steel plate 2, so that the linear motor car travels along the longitudinal direction of the secondary side plate 111 in a predetermined manner. However, a large reaction force of the driving force at that time is received in the longitudinal direction, an overhang portion 6 between the concave portion 7 and the convex portion 9,
The strong mechanical connection between 6'and the underhang portion 8 sufficiently resists the shearing force not only in the longitudinal direction but also in the direction orthogonal to this, and also has a strong vertical peeling force due to thermal behavior such as temperature change. Is prevented by a strong mechanical coupling between the overhang portions 6 and 6'and the underhang portion 8, and the height change beyond the height of the set unit does not occur.
Further, since the joint surface 11 between the mild steel plate 2 and the aluminum plate 3 is closely adhered to each other, no corrosion or the like is caused by sea breeze or submergence, so that the two are not separated from each other and always have a sufficient design The tightness of the street is maintained to allow the linear motor car to run as designed.

Next, in the embodiment shown in FIG. 2 (a cross-sectional view similar to FIG. 1), in the concave portion 7 on the side of the mild steel plate 2 on the joint surface, an upwardly-directed projection 10 is formed at substantially the center thereof. This is a mode in which the joining area can be made larger and the force that opposes the shearing force can be made larger, and the substantial operational effects are the same as those in the above-described embodiment.

Further, in the secondary side plate 113 of the embodiment shown in FIG. 3 (a cross-sectional view similar to the above-mentioned embodiment), the one-flow type underhang portion 8 and the overhang portion 6 are formed symmetrically on the left and right in the width direction. This is a mode that is extremely effective and can be manufactured at low cost when it is laid on a straight running portion or the like.

Next, the embodiment shown in FIG. 4 is the most general type in which so-called recessed type recesses 7'on the mild steel plate 2 side and corresponding protrusions 9'on the aluminum plate 3 side are alternately formed in a zigzag manner in the cross section in the width direction. As described later, this embodiment is
This is a mode in which the design can be freely performed in the vertical, horizontal, or diagonal directions and can be performed at low cost.

In the embodiment shown in FIG. 5, the pitch of the overhang portion 6 "and the underhang portion 8'on the overhang portion 6" of the concave portion 7 and the underhang portion 8'of the convex portion of the embodiment shown in FIG. It is a mode in which a secondary uneven portion having a smaller pitch is formed on each joint surface so that the mild steel plate 2 and the aluminum plate 3 are more firmly adhered to each other.
This is a mode in which a large drag force can be applied to the shearing force and the peeling force at the curved portion when the linear motor car is running.

Thus, in each of the above-mentioned embodiments, corrosion may occur between the mild steel plate 2 and the aluminum plate 3 with time depending on the laying condition, but since the corrosion generally occurs with volume expansion, the overhang portion 6 expands, and as a result, a more tightly bound state appears due to the underhang portion 8. In order to cope with this situation, the embodiment shown in FIG. While the joint surface with the plate 3 is a type of direct surface contact between metals of different materials, in order to prevent corrosion from occurring at the joint surface due to a difference in corrosion potential between the two, for example,
This is a mode in which a thin plate-shaped panel 12 such as zinc chromate is interposed between the two so as to enhance the corrosion prevention function between them, but the mild steel plate 2 and the aluminum plate 3 are used as the panel 12.
The resistance against the shearing force and the peeling force when the material is tightly tightened via is sufficiently guaranteed.

In the embodiment shown in FIG. 7, the mild steel plate 2 is coated with an anticorrosion paint lining 12 'such as zinc paint on the lower side of the thin plate-like panel 12 of the embodiment shown in FIG. This is a mode in which the anticorrosion function is further promoted.

Thus, in this embodiment, the anticorrosion paint may be applied to the aluminum plate 3 side, or the adhesive having the anticorrosion function may be replaced with the anticorrosion paint.

The arrangement mode of the concave portion 7'having the underhang portion and the convex portion 9 having the overhang portion is the eighth.
Like the recess 7'of the polymer 118 of the embodiment shown in the figure, it may be arranged in a zigzag shape in the longitudinal direction as a whole in one direction, or as the recess 7 "of the embodiment shown in FIG. Various arrangement modes are possible, such as the arrangement in which they may be inclined so as to face each other in the substantially longitudinal direction.

Needless to say, the embodiment of the invention of this application is not limited to the above-described embodiments, and for example, the zigzag-shaped uneven portion having a plurality of steps in the height direction with respect to the underhang portion 8 and the overhang portion 6. It is possible to adopt various modes such as providing.

In addition, it goes without saying that the mild steel plate and the aluminum plate can be replaced with other materials in terms of design modification.

And the target as an application example is not only the secondary side plate on the road side of the iron rail running linear motor car,
For example, polymer that is tightly adhered and tightened by different materials under various conditions such as train lines, severe sliding and vibration, machine tools that are operated under conditions with a large temperature difference, or other structures. Are all applicable to.

<Effects of the Invention> As described above, according to the invention of this application, in the polymer in which the secondary side plate on the road surface side of the linear motor car is desired to be adhered and tightened in the longitudinal direction by the dissimilar metal materials from various preconditions, both materials can be used. Is a concave part formed along the longitudinal direction of the underhanging part of one metal body or the like on the mutual joint surface without using the functional tightening with bolts and the like, and the same length of the material of the other metal body or the like. Due to the structure in which the convex part that forms the overhanging part along the direction is mechanically tightly engaged in every corner, longitudinal, lateral, and diagonally applied repeatedly at high frequency. It has an excellent effect that it can maintain a stable and tight tightening state with time against shearing force and peeling force in the direction, and can maintain the functions of the linear motor car etc. sufficiently stably as designed. To be done.

Further, the joining surfaces of the two can only better reveal a tightly connected state with time through means such as plastic pressure bonding by tightly engaging the underhanging portion along the longitudinal direction over the corners of the overhanging portion. However, since the overhang part and the underhang part become a kind of labyrinth seal state, the corrosive body does not enter the joint surface even when exposed to the environmental condition of the corrosive atmosphere, and one material and the other material The effect that peeling does not occur on the joint surface with

Even if corrosion unexpectedly occurs, there is an excellent effect that the volume expansion due to the rot places the overhanging portion and the underhanging portion further tightly bonds.

Then, by interposing a thin film-shaped metal anticorrosion panel or the like on the joint surface of one material and the other material,
Even though it is premised on the difference in corrosion potential between the two materials, the excellent effect that the corrosion does not enter and the function maintenance is much improved is exhibited.

Further, since the concave portion of the underhang portion and the convex portion of the overhang portion can express the tightened state in various design modes over the longitudinal direction, it is excellent in that there is a great degree of freedom in design for the purpose. The effect is played.

In addition, since both molding and close tightening can be done by mechanical processing and assembly, especially the formation of overhang and underhang in the longitudinal direction can be done at low cost, so the initial cost can be kept low. In addition, it is possible to obtain the excellent effect that it is economically extremely advantageous in addition to the reduction of the maintenance cost due to the maintenance of the tightly tightened state over time at every corner.
