Each rail air pipe 6 can bear the air supply of the cab of a plurality of travelling cranes 5 at the same time, and each travelling crane 5 is provided with a group of conversion connectors 9 which independently operate and do not interfere with each other.
According to the air supply system of the travelling crane air rail, in the specific working process, ambient air enters the rail air pipe 6 after being processed by the air processing unit 8, and the connecting sealing strip 11 in the rail air pipe 6 is in closed connection with the mounting bracket 22 under the action of air pressure and external force, so that air leakage is prevented;
when the carriage 7 stands still, the opening wheel 12 on the conversion connector 9 props up the connecting sealing strip 11 at the position of the opening wheel, so that a ventilation gap 13 is formed between the connecting sealing strip 11 at the position of the conversion connector 9 and the mounting bracket 22, the conversion connector 9 is communicated with the carriage 7, local ventilation is realized, and air in the track air pipe 6 enters the conversion connector 9 and then enters the carriage 7;
when the carriage 7 moves, the conversion connector 9 is connected with the carriage 7 through the carriage connecting bracket 18 and the converter connecting bracket 19, the carriage connecting bracket 18 pushes the converter connecting bracket 19 to move, so that the conversion connector 9 moves relative to the track air pipe 6, in the moving process of the conversion connector 9, the opening wheel 12 props up the connecting sealing strip 11 at the position where the conversion connector 9 moves, a ventilation gap 13 is formed at the position where the conversion connector 9 is positioned, air flow in the track air pipe 6 flows into the carriage 7 through the conversion connector 9, ventilation can be kept all the time in the moving process of the carriage 7, and the abrasion to the connecting sealing strip 11 is small;
the carriage 7 continuously moves, and the connecting sealing strip 11 at the position where the carriage 7 moves returns to a sealing state under the wind pressure and the external force of the rail wind pipe 6, so that the air flow in the rail wind pipe 6 is prevented from leaking.
Meanwhile, in the ventilation process of the cab, the conversion connector 9 is in pushing and touching connection with the traveling crane 5, and the two travel paths are not mutually influenced, so that stable wind taking is ensured.
The above examples are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall within the scope of protection defined by the claims of the present invention without departing from the spirit of the present invention.
