Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is disclosed in Japanese Patent Application No. 48-30425 (Japanese Patent Publication No. 51-4
By improving the invention related to the air blowing device for the underfloor of a vehicle proposed in Publication No. 2423), the electrical equipment of trains, etc., which is not suitable for washing with water, is removed, placed on a blowing trolley, and carried into the blowing room. This invention relates to an air blowing device that can perform dust removal and cleaning evenly by air jetting, etc., and can also prevent dust from scattering.

Traditionally, underfloor equipment on trains and other vehicles has mainly consisted of electrical equipment.
This is a well-known place where washing with water is not possible.

Therefore, removal and cleaning of attached dust has had to depend on manual operations such as air blowing.

Therefore, Japanese Patent Application No. 48-30425 (Special Publication No. 51-42)
No. 423) proposed an air blowing device for under the floor of a vehicle, but when it was actually used, it was discovered that electrical equipment installed under the floor of a vehicle could be cleaned automatically by air blowing without removing it from the vehicle. As a result, parts such as the mounting parts that are in contact with the underfloor of the vehicle or parts that are behind the vehicle become blind spots, and there are disadvantages such as the fact that there are places where dust cannot be completely removed.

Therefore, in order to remove dust from these areas, the vehicle had to be hoisted up and the blind areas were manually blown out, which resulted in a very low work efficiency.

The present invention was created in order to eliminate the above-mentioned drawbacks, etc., and its purpose is to automatically rotate a table for removing and placing electrical equipment installed under the floor of a train car. Furthermore, a plurality of manual rotary tables are installed in this rotating table, and a blowing cart is provided which can be moved on rails and freely carried into the blowing chamber, and furthermore, the blowing cart is carried in. To provide an air blowing device in which the air blowing chamber is shielded with a shutter that can be opened and closed, thereby making it possible to evenly remove dust from electrical equipment, etc., and also improving work efficiency and enabling automation. There is something to do.

In other words, the gist is that an air blowing chamber is formed on a floor surface on which mobile railway rails are laid, consisting of both side walls, a ceiling that can be opened and closed, and walls of the front and rear shirts. A suction port is provided on one side wall, an entrance is provided on the other side wall, a dust collection mechanism is connected to the suction port, and railway rails for loading and unloading that can be connected to the railway rails are arranged at both ends of the railway rail for transportation.
