[Detailed description of the device]

[Industrial applications]

 The present invention relates to a mounting means for a rail pantograph sliding plate, and more particularly to a carbon sliding plate mounting jig capable of remarkably reducing abrasion of a trolley wire.

[0002]

[Prior art]

 As is well known, railway pantographs have a structure in which a sliding plate is attached to a current collecting boat that is mounted on a diamond-shaped frame by a restoring spring. The sliding plate is conventionally made of a metal-based material such as cast alloy or sintered alloy. However, carbon-based materials that can reduce wear of mating materials such as trolley wires and electromotive rails, that is, carbon sliding plates, have recently begun to be used.

As a material of the carbon sliding plate, there are a molded body made of carbon and graphite alone, and a carbon / metal composite material that makes use of the excellent sliding characteristics of carbon and the electric conductivity of metal. In this case, it is difficult to braze and join with a metal, and it is difficult to screw a bolt or the like directly into the molded body because of its low strength.

As a conventional mounting method of the carbon slide plate, there is a holding metal fitting method shown in FIG. 4, for example. In this method, a carbon sliding plate 1 having a projection 2 and a groove 8 on the bottom is slid from the end of a holding metal fitting (sheath) 3 fixed by a current collecting boat 5, a bolt 6 and a nut 7. The structure is such that it is integrated with the current collecting boat 5, and is fixed by the portion of the protrusion 2 and the holding portion 4 of the holding metal fitting 3.

That is, since the carbon sliding plate is insufficient in strength, it is difficult to directly fix it with a bolt like a metallic sliding plate, and therefore the carbon sliding plate is attached via the holding metal fitting 3.

[0006]

However, in such a carbon sliding plate mounting method, since the groove 8 is cut in the carbon sliding plate itself, if the carbon sliding plate is excessively worn, the There is a risk of vertical breakage in parts. Therefore, since the effective portion (wear allowance) of the carbon slide plate is above the bottom of the groove 8, it is necessary to thicken the slide plate itself, and it is necessary to make the protrusion 2 part also made of carbon. Further, by making the pressing metal fitting 3 essential, there is a drawback that the weight of the pantograph current collector increases and the cost of the sliding plate increases. Further, in the case of the conventional holding metal fitting method, since the taper processing of the protrusion 2 is performed by using the diamond grindstone, the machining cost becomes high due to the problems of the grindstone life and the machining speed, and the cost of the sliding plate also increases. It is the cause. On the other hand, recently, along with the speeding up of railways, weight reduction of pantograph current collectors is required.

This invention aims to reduce the weight and cost of the pantograph current collecting boat, and to reduce the thickness of the carbon sliding plate and to securely attach the carbon sliding plate to the current collecting boat. Is to provide.

[0008]

[Means for Solving the Problems]

 This invention (1) interposes an intermediate member between a carbon sliding plate and a current collecting boat, and allows the intermediate member and the carbon sliding plate to be fitted in a concavo-convex shape. The structure is such that it is joined and integrated with an adhesive, and is fastened to the current collecting boat with a bolt through the female screw processed into the intermediate member, (2) The same sliding member made of carbon and the intermediate member as described above (3) An integral structure with the same intermediate member as described above, in which a concave portion is formed at the bottom of the above, the head is fitted into the concave portion, and the bolt is fastened to the current collecting boat with a bolt penetrating the intermediate member. In the bottom of the carbon slide plate of No. 1, a recess having an internal thread is formed on the inner circumference, a head with an external thread is screwed into the recess with an internal thread, and is fastened to the current collecting boat with a bolt penetrating the intermediate member. The point is that the structure is adopted.

[0009]

[Action]

 In this invention, the carbon sliding plate and the intermediate member are integrated by the concave-convex fitting means and the connecting means using the adhesive, so that the fixing strength of the carbon sliding plate can be secured. Here, the adhesive is not particularly limited, but a sheet-like adhesive is suitable. As a sheet-shaped adhesive, for example, REDU X (trade name) manufactured by CIBA-GEIGY (wall thickness of about 0.3 mm) is known.

In the case of the structure in which the carbon sliding plate and the intermediate member are integrated by the concave-convex fitting means and the joining means by the adhesive and fastened to the current collecting boat by the means (1), the carbon sliding plate is used. By making the plate side a concave portion and the intermediate member side a convex portion, not only can the carbon sliding plate be securely fixed to the intermediate member, but also the fastening bolts can be securely fixed by simply screwing it into the intermediate member. In addition, the wear allowance of the carbon slide plate can be made close to the surface of the intermediate member, so that the thickness of the carbon slide plate can be reduced and the jig weight can be reduced.

In the case of a structure in which the carbon sliding plate and the intermediate member are integrated by the concavo-convex fitting means and the joining means by the adhesive and fastened to the current collecting boat by the means of (2), the carbon sliding By making the plate side a convex portion and the intermediate member side a concave portion, not only the carbon slide plate is securely fixed to the intermediate member, but also the thickness of the intermediate member can be reduced, so that the weight of the jig can be reduced. In addition, the carbon sliding plate is not a groove, but the bolt head is fitted into an appropriately provided hole, so it is difficult to crack, and the wear allowance of the carbon sliding plate can be made close to the bolt head surface. Therefore, the jig weight can be reduced.

In the case of the structure in which the carbon sliding plate and the intermediate member are integrated by the concave-convex fitting means and the joining means by the adhesive and fastened to the current collecting boat by the means (3), the carbon sliding plate is used. By making the plate side a convex portion and the intermediate member side a concave portion, as in the case of (2) above, not only the carbon slide plate is securely fixed to the intermediate member but also the thickness of the intermediate member can be reduced. As a result, the weight of the jig can be reduced, and since the wear allowance of the carbon sliding plate can be kept close to the head surface of the bolt, the weight of the jig can be reduced. Further, since the head of the bolt is screwed into the carbon slide plate, the fastening bolt can be more securely fixed to the carbon slide plate, and the electrical resistance can be reduced because the fastening bolt directly contacts the carbon slide plate.

The material of the intermediate member in the present invention is not particularly limited, but for example, if the one made of aluminum (density 2.7 g / cm ³ ) is used, the carbon sliding plate material (the density varies depending on the product type) Is generally 3.0 to 3.8 g / cm ³ ) It is possible to further reduce the weight by decreasing the density.

It is a longitudinal cross-sectional view, 11, 21, 31 are carbon sliding plates, 12, 22, 32 are intermediate members, 13 is a sheet-like adhesive, and 14, 24, 34 are fastening bolts.

That is, FIG. 1 shows a means for fitting the carbon slide plate 11 and the intermediate member 12 into a concave and convex shape by processing the carbon slide plate 11 side into a concave shape and the intermediate member 12 side into a convex shape. The carbon sliding plate 11 and the intermediate member 12 are fixed to each other with a sheet-like adhesive 13 interposed on the joining surface. A female screw hole 12-1 for fastening is provided at an appropriate interval in the longitudinal direction at the center of the intermediate member 12, and a bolt hole corresponding to this female screw hole 12-1 is formed in the current collecting boat 5. It is set up.

When the central portion of the intermediate member 12 is formed in a convex shape, the wall thickness of the intermediate member becomes large, so that many female threads for fastening can be taken. However, since the weight increases as the thickness of the intermediate member increases, when adopting this concavo-convex fitting method, a material having a low density such as aluminum may be selected as the material of the intermediate member.

When the carbon slide plate 11 is attached to the current collecting boat 5, the carbon slide plate 11 and the intermediate member 12 are integrally formed with the sheet-like adhesive 13 and are drilled in the current collecting boat 5. The female screw hole 12-1 provided in the intermediate member 12 is aligned with the bolt hole, and the fastening bolt 14 is screwed into and fixed to the female screw hole 12-1 of the intermediate member 12.

In the case of the mounting jig shown in FIG. 1 described above, the effective portion (wear allowance) of the carbon sliding plate 11 is close to the convex upper surface of the intermediate member.

FIG. 2 shows a means for fitting the carbon slide plate 21 and the intermediate member 22 into a concave and convex shape by processing the carbon slide plate 21 side into a convex shape and the intermediate member 22 side into a concave shape. The method is adopted, and the carbon-made sliding plate 21 and the intermediate member 22 are fixed to each other by the sheet-like adhesive 13 interposed on the joint surface. A plurality of holes 21-1 for fitting the heads 24-1 of the fastening bolts 24 are provided at appropriate intervals in the longitudinal direction at the center of the carbon sliding plate 21 and further correspond to each hole. Then, the intermediate member 22 and the current collecting boat 5 are provided with bolt holes.

In the case of a method in which the carbon sliding plate 21 side is convexly shaped and the intermediate member 22 side is concavely shaped to be fitted in a concave and convex shape, the carbon sliding plate 21 can be made thicker, The height for inserting the bolt head 24-1 can be secured, and the thickness of the intermediate member 22 can be reduced, so that the overall weight can be reduced.

When the carbon slide plate 21 is attached to the current collecting boat 5, the carbon slide plate 21 is fitted with the head 24-1 of the fastening bolt 24 in the hole 21-1 of the carbon slide plate 21. The intermediate member 22 and the intermediate member 22 are integrated with each other by the sheet-like adhesive 13, and the fastening bolts 24 are passed through the bolt holes formed in the intermediate member 22 and the current collecting boat 5 and tightened with the nut 25.

In the case of the mounting jig shown in FIG. 2, the effective portion of the carbon sliding plate 21 is close to the top surface of the head portion 24-1 of the fastening bolt 24.

FIG. 3 shows a means for fitting the carbon slide plate 31 of carbon / metal composite material and the intermediate member 32 in a concave-convex manner. A method is adopted in which each side is processed into a concave shape and concave and convex are fitted, and the carbon-made sliding plate 31 and the intermediate member 32 are fixed by the sheet-like adhesive 13 interposed on the joint surface. However, in the case of FIG. 3, a female screw is cut on the inner circumference of the hole 31-1 into which the head portion 34-1 of the fastening bolt 34 provided in the central portion of the carbon slide plate 31 is fitted, and this female screw is used. A male screw is cut on the head portion 34-1 of the fastening bolt that is screwed into. The female screw holes 31-1 are provided in the central portion of the carbon slide plate 31 at appropriate intervals in the longitudinal direction, and the intermediate member 22 and the current collecting boat 5 are bolted in correspondence with the holes. Holes are drilled.

When the carbon slide plate 31 is attached to the current collecting boat 5, when the head 34-1 of the fastening bolt 34 is screwed into the female screw hole 31-1 of the carbon slide plate 31, carbon is used. The sliding plate 31 and the intermediate member 32 are integrated with the sheet adhesive 13, and each fastening bolt 34 is passed through the bolt holes formed in the intermediate member 32 and the current collecting boat 5 and tightened with the nut 35. . When the carbon slide plate 31 is made of carbon / metal composite material as described above, the carbon slide plate 31 is not likely to be broken even if it is attached to the current collecting boat 5 by screwing.

In the case of the mounting jig having such a structure, since the structure is the same as that in FIG. 2, the overall weight and the effective portion of the carbon slide plate 31 are the same as those in FIG. Since the heads of the bolts 34 for screws are screwed onto the carbon slide plate 31, not only can the fastening bolts 34 be fixed to the carbon slide plate 31 more reliably, Since the bolt 34 directly contacts the carbon slide plate 31, the electric resistance can be reduced.
