PROBLEM TO BE SOLVED: To provide an air blow dust collecting device and the like with a simplified configuration for electric power supply and easy to be stored.SOLUTION: An air blow dust collecting device 2 blowing compressed-air to a vehicle MC and collecting dust removed by the blow in a building 100 in which a trolley line 6 extends along the vehicle MC, comprises: a carriage 10 configured to be movable on a travel track set along the vehicle MC as well as movable in a delivery-and-storage-direction connecting a storage area 102 set to be separated from the vehicle MC and the travel track; a dust collector 11 mounted on the carriage 10; a travel support part 12 disposed on the carriage 10 and configured to be able to be movable in the delivery-and-storage-direction; a current collecting part 15 disposed on the travel support part 12 and configured to be able to slidably contact with the trolley line 6. When the carriage 10 or the like travels in the delivery-and-storage-direction, the travel support part 12 moves the current collecting part 15 relatively to the carriage 10 or the like to maintain a position of the current collecting part 15 with respect to the trolley line 6.SELECTED DRAWING: Figure 11 |
