Abstract

The utility model relates to a middle-sized centrifugal nodular cast iron pipe cement coating and lining machine and belongs to the technical field of centrifugal nodular cast iron pipe cement. The technical scheme includes that a stepping conveyer is installed below a machine frame. A driving supporting wheel assembly and a driven supporting wheel assembly are installed on the machine frame. A catch wheel is installed in one side end portion of the machine frame, close to the driven supporting assembly. A middle supporting wheel assembly is installed between the driving supporting wheel assembly and the driven supporting wheel assembly. The driving supporting wheel assembly, the middle supporting wheel assembly and the driven supporting wheel assembly are respectively provided with a clamping wheel. Each clamping wheel is controlled to lift through a hydraulic cylinder. According to the middle-sized centrifugal nodular cast iron pipe cement coating and lining machine, a set of supporting wheels and a set of clamping wheels are added between the two sets of the supporting wheels and the two sets of the clamping wheels, and therefore when the middle-sized centrifugal nodular cast iron pipe cement coating and lining machine rotates rapidly in the process of the cement coating and lining, jerk value is small, operation is steady and quality of coating and lining is good. The middle-sized centrifugal nodular cast iron pipe cement coating and lining machine is better in the quality of coating and lining of the middle-sized nodular cast iron pipe cement and is capable of two types of coating and lining nodular cast iron pipe cement with qualifications of DN300 and DN350, and therefore ranges of coating and lining types are enlarged.
