The manual operating unit 470 is installed at one side of the operating gear 446, and when the opening and closing operation of the cover cover 220 is not possible due to a failure of the driving motor 402, the opening and closing of the cover cover 220 is performed manually. In order to achieve this, the gears 446 and the manual gears are selectively engaged with the gears 474 to rotate the gears 446, and the manual gear 474 is configured to have a predetermined rotational force toward the manual gear 474. An operation handle 476 is configured to transmit the same.

The manual operation unit 470 is coupled to and separated from the manual gear 474 and the operating gear 446 so that the manual gear 474 is engaged with the operating gear 446 only when manual operation is required. The operation plate 442 is comprised.

In addition, when the opening and closing operation of the cover cover 220 is made through the manual operation unit 470, the indicator 478 may be further configured to indicate this.

Here, the indicator 478 is configured not only to operate the manual operation unit 470, but also to emit light when the opening and closing operation of the cover cover 220 is applied to the driving motor 402 and configured to indicate whether or not to operate. desirable.

In addition, the automatic cover device for a flat car of the present invention is configured such that power is applied to the drive motor 402 by the drive switch 150.

The driving switch 150 may be configured as a remote controller type consisting of buttons such as power supply and power supply cutoff, or may be made in a conventional limit switch method for determining whether to supply power depending on whether the driving switch 150 is in contact with the guide means 320.

For example, as shown in Figure 11, the drive switch 150 of the present invention is located on the guide frame 310, the end of the switch unit 520 is in contact with the guide means 320 is configured A driving plate 510 and an end portion of the driving plate 510 are configured, and a power switch 540 is configured to turn on / off a power supply depending on whether the driving plate 510 is operated.

In addition, the driving plate 510 has a rotary link 512 configured to rotate on the driving plate 510 when the guide means 320 and the driving plate 510 are in contact with each other. Can be.

In addition, the driving plate 510 may further include an elastic body 530 made of a component such as a spring for restoring the driving switch 150 to its original position after the rotation operation is performed.

When the driving switch 150 is in a non-contact state with the guide means 150, the driving means 150 determines that the guide means 320 is in operation and continuously supplies power to the drive motor 402 and contacts the guide means 320. If this is done, it is determined that the opening and closing operation of the cover cover 220 is completed is configured to cut off the power supplied to the drive motor (402) (OFF).

The automatic cover device for a flat car of the present invention configured as described above can be opened or opened without changing the facility of a conventional flat car, or installed without being removed, without interrupting the loading and unloading operation of cargo, In addition to preventing damage to the surrounding environment due to scattering dust of the loaded cargo during operation, it also protects the loaded cargo from rain, snow and wind, and prevents accidental fire accidents of cargo of ignition materials such as anthracite or bituminous coal. It is an invention that can be made.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

The present invention relates to an automatic cover device for a flat car, can be used in the manufacturing industry of flat cars.
