Description

[Detailed Description of the Invention] The present invention relates to an improvement of a sun line support device for a main electric motor for driving a vehicle.

Generally, the main electric motor for driving a vehicle is mounted on the bogie of a locomotive, and its marking line is connected to the distribution line of the power supply device via a terminal block installed under the floor of the car body. In order to prevent excessive external force from being applied to the marking line due to changes in the relative position of the car body and bogie in the left-right direction that occur when traveling on straight and curved sections, the marking line is placed under the floor of the car body using chains, etc. It is hung so that it can be moved freely.

However, with this configuration, the Hiji Line cannot be suspended below the car body floor unless the car body is placed close to or placed on the bogie. The work involves inserting a part of the body into a narrow gap, which is not only inefficient but also undesirable in terms of injury prevention.

The present invention is an attempt to easily solve the above-mentioned problems in supporting the sun line of a vehicle traction motor.

The present invention will be explained according to the embodiment shown in FIGS. 1 and 2.

1 is a sunrise line, 2 is a presser plate, both ends of the presser plate 2 shown in Fig. 1 are on the same horizontal plane, but it rises toward the center,
Its upper surface forms a central portion 24 that is parallel to both ends.

The distance between the inner surface of the parallel portion of the central portion 24 and the lower surface of the end portion 23 is set to be approximately the same as the diameter of the sunrise line 1, or slightly smaller than that.

Bolt holes are bored at both ends of the holding plate 20 and at the opposite end of the wire dust 4.

The upper surface of the wire dust 4 is formed into a flat surface.

After placing a plurality of Hiji wires 1 on the electric wire dust 4, place the holding plate 2 on top of it so that the guide wire 1 is accommodated in the center, and tighten the bolt 3 to remove the Hiji wire. 1 is held between a holding plate 2 and wire dust 4.

A U-shaped receiving member 5 is integrally formed at the center of the lower part of the wire dust 4, and a pin 6 is provided to pass through the lower part of the receiving member 5 at a predetermined position.

9 is a washer loosely fitted onto the shaft of the pin 6, and 8 is the head of the pin 60.

Reference numeral 10 denotes a rectangular arm, and a rectangular hole 12 is bored in the center of the arm 10 in the longitudinal direction.

The end of the rectangular hole 12 located near the center of the arm 10 is a large hole 11.

The diameter of the large hole 11 is larger than the outer diameter of the head 8 of the pin 60, and the width of the rectangular hole 12 is slightly larger than the outer diameter of the parallel part 7 of the pin 6, but smaller than the outer diameter of the head 8. Set.

Therefore, the pin 6 can go in and out only through the large hole 11.

A shaft 13 with a hollow portion as an oil reservoir 15 is provided on the lower surface of the end portion of the arm 10 where the rectangular hole 12 is not formed.

A groove 14 is provided over a predetermined outer circumference of the shaft 13. The oil reservoir 15 communicates with the outside air through an opening 16 provided above.

Reference numeral 17 denotes a bearing, and a bolt 19 that passes through the outer circumferential wall of the bearing 17 facing the groove 14 and whose tip can protrude into the groove 14
is provided.

The bearing 17 is fixed to a truck 22 via a mounting seat 18 and a receiving member 20 that are connected with bolts 21.

In order to support the Hiji Line according to the present invention in such a configuration, the bearing 17 is fixed in advance to the receiving member 20 fixed to the trolley 22 using bolts 21, and the -Kichi Hiji Line 1 is held down. If the plate 2 and the wire dust 4 are held together, when the main motor is mounted on the truck, the pin 6 is inserted into the large hole 11 of the arm 10, moved in the direction of the rectangular hole 12, and the shaft 13 is inserted into the bearing 17. To remove the Hijisen 1, pull out the bogie 22 from the car body, then tighten the pin 6.
The electric wire dust 4 may be lifted by moving it to the position of the large hole 11, or the bolt 19 may be loosened and the electric wire dust 4 may be lifted together with the arm 10.

According to the present invention, the Hiji Line can be easily installed and removed with the bogie removed from the car body.
The above-mentioned problems in the conventional attachment and detachment of the drawing line can be effectively solved, and if the specific configuration of the present invention is also effective, the pin 6 can be attached to the long side of the arm 10 through the washer 9. Since the wire dust 4 is loosely fitted into the hole 12, there is a sliding and rotational movement force along the rectangular hole 12, while the shaft 1
3 is configured to be rotatably engaged in the bearing 17 via the bolt 19 and the groove 14, so when one end of the Hiji Line 1 is connected to the terminal block under the car body floor, the locomotive Even if the relative position of the vehicle body and trolley in the left and right direction changes while driving,
It can fully follow the fluctuations.

Furthermore, when the shaft 13 is inserted after injecting an appropriate amount of oil into the bearing 17, the air in the oil sump 15 is pushed by the oil and released into the atmosphere from the opening 16, and the oil sump 15 is filled with oil for a long period of time. Its practical effects, such as ensuring lubrication throughout, are remarkable.
