[Patent Document 1] Patent Registration No.: 10-0874868 (Registered Date: December 12, 2008)

Name: A dust collector for maintenance railway vehicles

Conventional Reference 1 relates to a dust removing device for railway vehicle maintenance. In order to remove dust and the like generated during maintenance of a railway car, a railway car maintenance workshop is provided with a shielding film for blocking dust on both sides of a maintenance passage, A dust shutting means having a branch pipe is provided and a flexible duct for sucking dust scattered in the flange pipe of the dust shut-off means is connected to be connected to the dust collector. In the maintenance of the passenger car as a railway car, If the dust and the like attached to the lower frame of the railway car and its surrounding parts are scattered and scattered, the scattered dust is not scattered to the outside by the dust shielding means but is collected and removed by the dust collector, And at the same time, air pollution around the maintenance work site can be prevented.

However, in the present invention, contrary to the above-mentioned configuration, it is intended to remove dust formed on a main transformer of a railway vehicle.

At the lower part of the recently manufactured electric railroad car, a main transformer or a transformer is mounted, and a cooling device (oil cooler), a filter (screen) and a blower for cooling are installed at adjacent positions. The transformer has a lot of heat, so it is equipped with an oil cooler and blower to cool the heat. During the blowing process, a lot of dust or foreign matter gets caught in the filter (screen wire netting), oil cooler, transformer and its surroundings. This may cause the transformer to be ineffective in heat dissipation, reduce cooling efficiency, and, in severe cases, cause a fire due to overheating of the transformer.

In the past, in order to remove dust and dirt from the main transformer, oil cooler, screen filter and surrounding area located in the narrow space below the vehicle, the filter cover was manually disassembled manually to clean the screen filter and peripheral devices come. In this case, since the main transformer is mounted on the lower part of the vehicle, the work space is so narrow that the work of the operator is very difficult, the operation takes a long time, and also the clean vibration can not be achieved.

In addition, since a number of transformers are installed in the lower portion of the railway vehicle, when the transformers are to be damped, the moving and damping operations are very inconvenient because they need to be cleaned while moving the positions from time to time.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a dust removing apparatus for a transformer and its peripheral components, The purpose.

The object of the present invention is to provide a portable dust collector for vibration damping of a transformer of a railway vehicle, which can prevent the performance of the dust-removing filter from being deteriorated due to accumulated dust due to a long time manufacturing operation of the dust-collecting filter used in the dust-

According to an aspect of the present invention, there is provided a portable dust collector for removing a transformer installed in a lower portion of a railway car and a transformer of a railway vehicle for removing dust and foreign matter adhering to the periphery of the transformer, A suction pipe 2 connected to a side of the filter 10 provided in the dust collector 1 and a suction pipe 2 connected to the suction pipe 2 at the front end of the suction pipe 2, A hood 3 connected to the transformer side by air suction and a transfer bogie 6 capable of moving the hood 3. The dust collector 1 is provided on the upper side of the filter 10, A diaphragm valve 13 is provided at an upper portion of the air tank 15 so that when compressed air is supplied by the valve operation of the diaphragm valve 13, Is sprayed to the bottom of the tank 15, The dust collector 1 is provided with an exhaust hole 8 at an upper portion thereof and a blower 12 is installed at a lower portion of the exhaust hole 8, A diaphragm valve 13 is provided below the blower 12 and an air tank 15 is provided below the diaphragm valve 13. A filter 10 is installed below the air tank 15, And a dust collecting hopper 4 is installed in a lower portion of the filter 10. A first door 41 is installed on the front surface of the blower 12 and a front surface of the diaphragm valve 13 and an air tank 15 And a third door 43 is installed on the front surface of the filter 10. The suction pipe 2 is formed in a bellows shape and is foldable And the transfer bogie 6 includes a table 22, a wheel 23 formed below the table 22, And a hood neck rest 21 which is vertically installed behind the seat 7. The hood rest 21 is provided with a hood 3 for holding the hood 3, The hood 3 is configured to have a horn shape or a square box shape so that the hood 3 is formed on the outer surface of the cooler cover 30. [ The hood (3) and the cooler cover (30) are magnetically attached to each other by including a magnet material.

According to the present invention, the damping operation on the transformer, especially the main transformer and its peripheral parts can be performed very conveniently, safely, quickly, and cleanly.

In addition, the present invention can remove the dust attached to the filter of the dust collector by the filter itself, so that it can be used for a long time without stopping the operation and without deteriorating the performance. That is, by spraying the pressurized air with the back pressure of the suction pressure against the dust filter, the dust attached to the filter can be removed by intermittent operation, and the dust removal operation can be performed for a long time without stopping the operation.

1 shows a transformer dust collector for a railway vehicle according to the present invention

As shown in the drawing, the present invention comprises a dust collector 1 corresponding to the main body, a suction pipe 2 connected to the dust collector 1, and a hood 3 connected to the front end of the suction pipe 2.

In the lower part of the dust collector 1, a dust collecting hopper 4 for collecting dust is provided, and an exhaust port 8 for exhausting is provided in the upper part. The hood (3) is provided with a conveyance truck (6) for the convenience of movement. A hood sheet (7) on which the hood (3) can be placed is provided on the conveyance truck (6).

The first, second and third doors 41, 42 and 43 are installed on the front surface of the dust collector 1 to inspect and replace the blower 12, the diaphragm valve 13, , And repair.

Fig. 2 shows the inside of the dust collector 1

As shown in the drawing, the inflow flange 14 corresponding to the dust suction portion is installed on the lower right side. The dust that enters through this space is discharged to the exhaust port 8 through the filter 10 by the suction action of the blower 12. In this case, a large amount of dust is attached to the outer surface of the filter 10 to be attached thereto.

The filter 10 has a hollow center and a vertically formed corrugated pipe or protruding surface, so that the filter 10 is configured to perform maximum adsorption filtering in a small area. Thus, the air sucked into the center through the outer surface of the filter 10 is sucked up by the clean air filtered by the dust.

An air tank 15 and a diaphragm valve 13 are further provided between the filter 10 and the blower 12. The diaphragm valve (13) is suitable for use in opening and closing a flow path of a fluid containing powder or foreign matter, and is convenient for maintenance. The function of the air tank 15 and the diaphragm valve 13 is to remove dust, dust, etc. adhered to the outer surface of the filter 10 in a large amount.

If a large amount of dust is adhered to the filter 10, the filtering performance is lowered and the suction pressure is increased. To prevent this, the diaphragm valve 13 connected to the compressed air supply portion for supplying compressed air is intermittently opened When the compressed air is injected, the supplied compressed air is supplied to the central cavity of the filter 10 via the air tank 15.

The actuation of the diaphragm valve 13 may be configured to sense the performance of the filter 10 or to automatically operate by sensing an increase in suction pressure.

A plurality of through holes are formed in the lower end of the air tank 15 toward the central cavity of the filter 10, though not shown. The air then exits from the left and right sides through the central cavity of the filter 10 to drop dust attached to the outer surface of the filter 10. (The lower end of the filter 10 is plugged) (17).

3 shows that an air tank 15 is connected under the diaphragm valve 13 and a plurality of filters 10 are installed in the lower part thereof.

4 is a moving truck 6 used when the hood 3 is mounted or moved.

The hood 3 is attached to the hood sheet 7 by mounting the hood sheet 7 and the hood neck rest 21 on the table 22, And the hood neck 25 is hooked to the hood neck 21 of the "u" shape. The reason why the moving carriage 6 is separately made is that the hood 3 and the suction pipe 2 are heavy and they are made of a separate carriage because they are inconvenient to move to a position to suck.

Fig. 1 shows a state in which the hood 3 is hooked on the conveying truck 6. Fig.

The suction pipe 2 shown in FIG. 1 is formed of a metal material or a plastic material, and is preferably made of a flexible material, and may be formed in a bellows shape. If the suction pipe (2) is formed into a bellows shape, it can freely bend, can be folded and stored, and is convenient to take to a position to suck.

Figure 5 illustrates a working method according to the present invention.

The main transformer or the transformer is installed on the bottom of the vehicle or on the side of the lower portion of the vehicle, depending on the type of railway vehicle. A cooler blower (not shown), an oil cooler (not shown) and a cooler cover 30 are installed adjacent to the main transformer, and the hood 3 is mounted thereon. The hood (3) is installed so as to sufficiently cover the periphery of the cooler cover, and when air is sucked into the hood, a vacuum is formed, and the hood (3) is sucked and dust suction operation is performed.

6 illustrates a cooler cover 30 on which the hood 3 is mounted. A cooler blower 55 is provided inside the cooler cover 30. It is needless to say that the cooler cover 30 shown here may have a circular shape or a box shape if the outer shape of the cooler cover 30 is a box shape.

The attachment of the hood 3 to the cooler cover 30 can be performed not by adsorption by vacuum adsorption but by a magnet. That is, it is possible to attach the magnet body to the attachment surface of the hood 3 or the hood 3 by attaching the magnet body.

The damping and adsorbing operation of the transformer dust according to the above configuration will be described again.

First, the dust collector 1 and the conveyance truck 6 are brought together near the transformer position of the railway car

The hood 3 is separated from the conveyance truck 6 and brought into close contact with the cooler cover 30 so that the hood 3 is attracted to the cooler cover 30 when the dust collector 1 is operated. Then, the oil cooler (not shown) installed inside the cooler cover 30, the cooler blower 55, the main transformer (installed inside the cooler blower 55) and the dust and dust attached to the periphery thereof are sucked The clean air is exhausted through the blower 12 and the exhaust port 8 through the filter 10 through the suction pipe 2 by the pressure.

When dust is continuously removed, dust is accumulated on the outer surface of the filter 10 contaminated with the dust gas, which lowers the filtering performance, increases the suction pressure, and causes an overload. Then, by the intermittent operation, the diaphragm valve 13 is opened and high-pressure air is injected through the excitation. Then, the injected air flows into the air tank 15 and is injected into the hollow of the filter 10 through the through hole formed in the lower surface of the air tank 15. The dust adhering to the outer periphery of the hollow hollow of the filter 10 falls downward and is accumulated in the receptacle 17 via the dust hopper 4. [

According to the above-described operation, the dust and polluted gas around the transformer and its surroundings can be conveniently and cleanly removed, and the filter 10 can be used for a long period of time without replacement for a predetermined period of time.
