Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation method for transporting a relatively large-capacity transformer by rail by a hanging type freight car, and a coupling fitting used for the transportation method.

[0002]

2. Description of the Related Art The hanging method is known as a method for transporting large capacity transformers by rail (for example, Electrical Engineering Handbook 1988 edition P.688). This suspension type transport method of transformer uses a suspension type freight car (also called Schnabel car), which is a dedicated freight car, but the transport tank of the transformer itself constitutes a part of the freight car. It is known as a transportation method suitable for transportation of large-capacity transformers because the size can be set to the transportation limit. In this system, the maximum size of the transformer package is 3,800 mm in width and 4,300 mm in height from the track, and the maximum length in the traveling direction may exceed 10 m.

FIG. 4 is a schematic front view showing a transporting state of a transformer in which a hanging type freight car is used. Since it is symmetrical, the illustration on the left side of the center line indicated by a chain line is omitted. In this figure, the transport tank 1 of the transformer is sandwiched between the hanging wagons 2 on both sides, and the right-hand side hanging freight car 2 shown in the figure has two carriages 22 and one end on top of which. The schnabel 21 is rotatably mounted, and the schnabel 21 is provided with a shaft hole 23. Schnabel is a German word for the beak of a bird.
Because the shape of the is similar to the beak of a bird, the hanging wagon is also called a Schnabel car as described above.

A detachable hinge 12 is attached to the transport tank 1 via a mounting seat 11 which is attached to the transport tank 1 by welding. The detachable hinge 12 also has a shaft hole of a Schnabel 21.
A shaft hole 123 through which the shaft is inserted is provided in common with 23. In the transportation state, the shaft rod is commonly passed through the shaft hole 23 and the shaft hole 123, the left end upper part of the schnabel 2 comes into contact with the contact plate 13 and pushes against each other, and the weight of the transport tank 1 and its contents is supported together with the shaft rod. There is. As long as the left end of the Schnabel 21 does not come into contact with the contact plate 12, the detachable hinge 12 and the Schnabel 21 have a hinged structure that is rotatable around the shaft, so that the structure on the transport tank 1 side is a detachable hinge. being called.

FIG. 5 is a partially enlarged view of the mounting seat 11 and the detachable hinge 12 of FIG. 4, and FIG. 6 is a side view showing only the left side when the detachable hinge 12 of FIG. 5 is removed. In these figures, a mounting seat 11 for mounting the detachable hinge 12 by bolting is attached to the side surface of the transport tank 1 by welding,
The mounting seat 11 and the detachable hinge 12 are shown by a chain line in FIG.
The individual fixing bolts 14 are fixed by being inserted into the bolt holes 141 of FIG. 6 and tightened. The mounting seat 11 is composed of a vertical plate 111, a seat 113 and a strengthening 112, and a detachable hinge 12 is a vertical plate 121, a seat 113, a strengthening 122 and a shaft hole provided at a position where the vertical plate 121 projects to the right side of FIG. It consists of 124.

Sixteen bolt holes 141 shown in FIG. 6 are provided in each of the seats 113 and 123, and the fixing bolt 14 is penetrated into the bolt holes 141, and a nut is attached to fix the bolts. As shown in the figure, the lower the density of the bolts 14 is, the stronger the force between the seat 113 and the seat 123 is, the compressive force that pushes each other in the upper part and the pulling force that tries to separate from each other in the lower part. On the other hand, the fixing bolt 14 does not bear the force, and the fixing bolt 14 bears all the force with respect to the pulling force. The compression force of the upper part is borne by the contact plate 13. As shown in FIG. 6, the mounting seats 11 are provided on a part of both sides of the tank of the transportation tank 1 near both sides, but the hitting plate 13 is provided over the entire width so as to bridge the left and right detachable hinges 12. .

[Problem to be Solved by the Invention] One hanging type freight car 2
Only one unit can be transported with, and it is natural for large-capacity transformers where the size of the transformer is near the transport limit, but in the case of medium-capacity transformers, the suspended freight car 2 transports larger transformers. Although it can be done, only one unit can be transported, so there is a problem that the transportation cost is high. Of course,
Even if a low-floor vehicle, which has a smaller capacity and is another transportation method of rail transportation, can be transported, such a problem does not occur, but it cannot be transported unless the suspension method is used and the suspension wagon 2 is sufficient. In some cases, the size and weight of the transformer may be so large that there is a margin, and the above-mentioned problem of high price cannot be solved.

An object of the present invention is to solve the above problems and provide a transformer transportation method and a coupling fitting used for the transformer which can reduce transportation cost in a transformer transported by a hanging type freight car. To do.

[0009]

In order to solve the above problems, according to the present invention, in a method of transporting a transformer by a hanging type freight car, a transport tank of a plurality of transformers is connected in a traveling direction to a machine. Be integrated and transported. In addition, the transport tanks of two adjacent transformers shall be mechanically integrated by fixing them with bolts via connecting fittings. Further, it is assumed that the position and size of the bolt hole of the connecting fitting are substantially the same as those of the detachable hinge that is detachably attached to the transport tank of the transformer and is fixed to the hanging type freight car during transportation. Further, the mounting seats, which are welded to the transport tank of the transformer, face each other and are fastened with fixing bolts so that the transport tanks of two adjacent transformers are mechanically integrated and transported.

[0010]

In the configuration of the present invention, when a transformer is transported by rail by a suspended type freight car, the transport tanks of a plurality of transformers are connected in the traveling direction and mechanically integrated for transportation. Since the cost is almost the same as the case of transporting only one unit, the transport cost per unit is 1 / the number of units transported at the same time. In addition, if two adjacent transport tanks are mechanically integrated by fixing them with bolts via connecting metal fittings, each transport tank will have a different connection structure even if the structure is different. Can be connected using a connecting fitting. Also, when using a detachable hinge that is detachably attached to the transport tank and fixed to the hanging type freight car during transportation, by using a connecting metal fitting that matches the dimensions of the mounting seat to which the detachable hinge is attached, It becomes possible to standardize the mounting brackets and detachable hinges as well as the connecting fittings. Also, if the mounting seats of the two transformers have the same dimensions, the connecting brackets can be omitted by directly fixing the mounting seats to each other without using the connecting brackets. Is shortened.

EXAMPLES The present invention will be described below based on examples.
FIG. 1 is a front view of the embodiment of the present invention when transporting a transformer by a suspended type wagon. Since the left side of the figure is symmetrical to the right side, most of the illustration is omitted. Also, FIG. 4 of this figure
The same components as those of 1 are assigned the same reference numerals to omit redundant description. In this figure, the transport tank 1A in which the contents of the transformer are stored and the transport tank 1B are connected through a connecting metal fitting 3 and are mechanically integrated. Then, the Schnabel 21 on the right side of the hanging freight car 2 is attached to the detachable hinge 12 attached to the right end of the transport tank 1A, and the left end of the transport tank 1B is attached to the detachable hinge 12 in the same manner as the right side, although not shown. The schnabel 21 on the left side of the hanging type freight car 2 is attached and transported in this state. The connecting fittings 3 are attached to the mounting seats 11A and 11B of both transport tanks 1A and 1B.

FIG. 2 is a partially enlarged view of the connecting fitting of FIG. 1 and the members around it. In this figure, transport tanks 1A, 1B
The mounting seats 11A and 11B, which are attached by welding, should have detachable hinges attached if they are to be transported one by one. The transport tank 1A and the transport tank 1B do not necessarily have to have the same specifications and dimensions. Although shown as almost the same in this figure, the mounting seat 11A and the mounting seat 11B may have different dimensions. At that time, it is meaningful to use the connecting fitting 3.

The connecting fitting 3 has a structure similar to that of the mounting seat 11 and the detachable hinge 12 of FIG. 5, and is composed of seats 32 on both sides, a vertical plate 31 and a strengthening plate 33. Since the structures of the mounting seats 11A and 11B are clear from the similarity of FIG. 5, reference numerals of the seats, the vertical plates and the strengthening plates are omitted. Figure 3
FIG. 3 is a partially enlarged view similar to FIG. 2 showing a different embodiment of the present invention. The difference from FIG. 2 in this figure is that the connecting fitting 3 is not used. Since the mounting seat 11A of the transport tank 1A and the mounting seat 11B of the transport tank 1B have the same size, the fixing bolts 14 can be attached to both sides without using the connecting metal fittings as shown in Fig. 3 because the positions of the bolt holes are the same. It can be fixed by tightening it through the bolt holes. Since the connecting metal fittings can be omitted, not only the cost of the connecting metal fittings can be reduced, but also the transport length can be shortened by the length of the connecting metal fittings in the traveling direction, so that the transportation can be carried out with a margin.

The dimensions of the mounting seats 11, 11A and 11B are the detachable hinge 12
By standardizing together, the dimensions of the mounting seats 11, 11A, 11B can be made the same even if the specifications such as the capacity of the transportation tank are different. On the contrary, when the mounting seats 11A and 11B have different sizes, the connection fitting 3 can be utilized to implement the present invention and contribute to the reduction of transportation cost. The number of transport tanks to be connected is not limited to two, but three
It may be a stand. The number may be selected as much as possible depending on the capacity of the hanging type freight car to be used.

[0015]

As described above, according to the present invention, when transporting a transformer by a hanging type freight car, a method of connecting a plurality of transport tanks in a traveling direction and mechanically integrating them to carry them all at once. By adopting, the transportation cost is almost the same as the case where only one vehicle is transported, so that the transportation cost per vehicle can be reduced to nearly one-tenth of the number of vehicles transported at the same time. In addition, if a method of connecting two adjacent transport tanks via connecting metal fittings is adopted, even if the dimensions of the connecting portions of the respective transport tanks differ, it is possible to connect using the connecting metal fittings that match each other. it can.

When the hinge fixed to the hanging type freight car at the time of transportation is a detachable hinge that is detachably attached to the transportation tank, use a connecting metal fitting suitable for the size of the mounting seat to which the detachable hinge is attached. As a result, it is possible to standardize the connecting fitting together with the mounting seat and the detachable hinge, and the connecting fitting can be used repeatedly, so that the cost of manufacturing the connecting fitting can be reduced. Also, if the mounting seats of the two transport tanks have the same dimensions, the connecting brackets can be omitted by directly fixing the mounting seats to each other without using the connecting brackets. Not only is it reduced, but the length during transportation is shortened by that amount, and there is the effect that there is room for transportation conditions.
