The invention discloses a pipeline descaling optimized running device. Three K10 motors are adopted to supply power to a walking mechanism, one SRF 300 motor drives a tool rest disc to enable a tool and the pipeline wall to slide relatively so as to clean dirt on the pipeline wall, and cleaning work of a whole pipeline can be carried out in a full-automatic manner, and when the detachable tool rest disc and the tool are used for cleaning, under the specific condition, according to the different pipe diameters, the tool rest disc with the proper size can be selected to be arranged on a motor shaft to be cleaned, according to different kinds of dirt, the proper tool is selected to be arranged on the tool rest disc to be cleaned, and the device can adapt to condensers with different pipe diameters and different kinds of dirt. Remote control running is achieved, a descaling device can move forwards, retreat and park, during clamping, brake and backing off can be achieved, and the device has the beneficial effects that standard parts are designed, and the device can adapt to different pipe diameters; according to the dirt, different tools are replaced, and the device is suitable for different dirt; remote control is achieved, and operation is convenient.
