After cleaning the railway bogie 5, the stopper member 10 of the stopper mechanism A is set to the retracted position again, and the lifting member 35 of the bottom/both side cleaning mechanism B is lowered to the lowered position, and,
With the arm member 10 of the upper surface/front surface cleaning mechanism C stopped at the retracted position on one side of the guide rail 6.6, the air cylinder 84 is operated and the fifth lever 83 is moved.
The cleaned railway bogie 5 is kicked out to the right in the figure and is guided out of the cleaning room 80 through an exit 81 having an opening/closing door by running on a guide rail 6.6, and the cleaning work is completed.

In the above embodiment, the air injection nozzle 9. ..., only compressed air is injected from 9, but in some cases,
It is also possible to project wood chips, walnut chips, etc. together with the jet air to increase the cleaning effect.

In this case, a recovery hopper for wood chips, etc., a circulating supply device for these wood chips, etc. are separately provided in the stepped portion 12.

As is clear from the above explanation, in this invention, after the railway bogie to be cleaned is accurately positioned at the cleaning position by the stopper mechanism, the numerous air injection nozzles of the elevating bottom and both side cleaning mechanism Air is sprayed from close range over a wide area following the underside and both sides of the railway bogie, blowing off dust, etc. from the underside and both sides. This cleaning device has a nozzle that follows the top and front surfaces of a railway bogie and sprays air from a close distance over a wide range to blow away dust, etc. from the top buttons and front and rear surfaces.

Therefore, according to this invention, air is blown onto the upper and lower surfaces, both sides, and the front and rear surfaces of the railway bogie from six directions and from close range, and the entire bogie is automatically and completely cleaned in a short period of time. You will be able to do this.

In addition, if the air injection nozzle is made into a rotating nozzle, the air can be sprayed over a wide range without weakening the injection force due to the turning movement, and if the air injection nozzle is made into a flexible rotating nozzle, the contact/bending movement causes blind spots. This makes it possible to blow air from all directions without causing any turbulence.

Furthermore, by reciprocating the air injection nozzles of each mechanism with an endless chain that communicates with the air cylinder, or by swinging them back and forth with a link lever linked to the air cylinder, each surface can be efficiently cleaned with a small number of air injection nozzles. I can do it.

In addition, the air injection nozzles on the side plate members of the elevating lower surface/both side surface cleaning mechanism are arranged separately at the front and rear parts of the entire length of the bogie, or the arm members of the traversing type upper surface/front and rear cylinder cleaning mechanism are installed on the railway bogie. If the air injection nozzles are arranged independently of each other at approximately half the total length of the arm members, and the air injection nozzles are divided and placed on each arm member, it is possible to repeatedly clean only the air injection nozzles corresponding to particularly heavily soiled areas. This improves cleaning efficiency.

In addition, if the stopper mechanism, the bottom/both side cleaning mechanism button, and the top/front/back cleaning mechanism are placed in a sealed cleaning chamber that communicates with the dust collector, the dust blown by each air injection nozzle will be collected in the cleaning chamber. The dust can be collected by suction into a dust device, and since the noise generated from the air injection nozzle is shielded within the cleaning room, it does not leak outside, making it possible to maintain a good working environment.
