PURPOSE:To prevent wire breaking, by supplying power to a portable motor for a lance pipe which moves through the inside of a casing along the longitudinal direction, by the intermediary of a trolley duct provided to a casing, and a power collector moving through the inside of a duct. CONSTITUTION:The soot blower is provided with a lance pipe 3 moving through the inside of a casing in the longitudinal direction, as well as with a gear box, and a motor 5. A lance pipe 3 cleans the devices such as a heat exchanger of a boiler and the like, by injecting an injection medium which is fed from an injection medium feed pipe 2, from the tip nozzle of a lance pipe 3. In this case, a trolley duct 9, which can be divided into a plural number of pieces, is provided to the under surface of top wall of a casing 6, along its longitudinal direction. A plurality of trolley wires 10 are provided to the inside surface of a duct 9, and they are connected to the source of power supply. A trolley wire 12, provided with a collector 11, is housed in the duct 9, freely movably, and the collector 11 is connected so as to supply power to a motor 5, by the intermediary of a wiring material 14 and a terminal box 15. |
