This application primarily discusses the manner of dual drive.

The conventional method at present adopts a technical scheme that a plurality of trolleys run synchronously in an electronic control mode. A rotating speed sensor is arranged on a motor rotating shaft or a transmission shaft, and the synchronous operation desire of each trolley is realized by collecting the angular speed of each trolley driving motor or transmission shaft. However, in practical application, due to the conditions of unbalance loading, impurities on the guide rail and the like, the wheels of the trolley and the guide rail often slip, and the phenomenon that the speeds of the left wheel and the right wheel are inconsistent still exists. Even if the rotating speeds of the motors are consistent, the linear speed running of the wheels is difficult to ensure, so that the scheme is still difficult to ensure the smooth running of the mud scraping and sucking machine.
