The purpose of this utility model is achieved in that it includes guide rail, drive motors, it is characterized in that: A shape air cooler is set with a horizontal guide rail that is parallel to each other respectively on the bracing frame up and down in power plant's direct air cooling system, horizontal guide rail is provided with a wheeled stent-type walking cleaning platform, cleaning platform is provided with a horizontal drive unit along the guide rail walking, this horizontal drive unit comprises successively: drive motors, reductor, synchronous cog belt and synchronizing jugged belt wheel, output shaft, road wheel.
The utility model is to adopt a motor, reductor, on the reductor lengthening output shaft two synchronous toothed belt wheels are installed, two flute profile belt wheels on the reductor by the flute profile band respectively with the power transmission shaft of two parallel installations on the flute profile belt wheel link to each other, road wheel is installed on the power transmission shaft, the reductor revolution drives power transmission shaft, road wheel rotation through the flute profile band, road wheel moves along guide rail, and the moving cleaning platform of holder moves along the guide rail direction.
Characteristics of the present utility model are:
The horizontal transmission mechanism of once mounting does not need to repeat the reliability height is installed.
Adopt wheeled transmission mechanism and flexible auxiliary wheel to support, guaranteed that cleaning platform operates steadily.
Because frequency converter is adopted in control, movement velocity can realize stepless speed regulation.
The utility model also has simple and reasonable, and is easy and simple to handle, easy to maintenance, safe and reliable to operation, characteristics such as long service life.
