Background

In the production of the nodular cast iron pipe, the surface of the nodular cast iron pipe is usually required to be cleaned, sprayed and the like, and the nodular cast iron pipe is used as a bell and spigot pipeline, and the movement of the nodular cast iron pipe in the cleaning or spraying treatment process is greatly limited due to the heavy mass and the large volume of the nodular cast iron pipe and the certain radian design between a bell mouth and the pipe wall. For example, when the outer wall of the nodular cast iron pipe needs to be cleaned, a transport vehicle capable of transporting the nodular cast iron pipe off line needs to be arranged at a specific position of a production line, the axial direction of the transported nodular cast iron pipe is off line, and the outer wall of the nodular cast iron pipe is cleaned in a room for cleaning the outer wall of the nodular cast iron pipe by shot blasting, and the mode has the biggest defects of discontinuous cleaning operation, long time for transporting the nodular cast iron pipe from off line to return line, extremely low production efficiency and very large floor area. If the traditional riding wheel transmission device is adopted to transport the nodular cast iron pipe, the height difference is generated when the bellmouth passes through the riding wheel, so that the nodular cast iron pipe jolts, the nodular cast iron pipe not only can easily fall off, but also the service life of the transportation device can be easily shortened or the workpieces of the transportation device can be easily damaged due to continuous jolting and vibration.
