Abstract:

It is urgent to develop automatic processing equipment for segment steel reinforcement cage of shield to solve the problems of large human input, unstable quality and high security risk when using artificial processing method. Based on the CZTZH1 project of ChangshaZhuzhouXiangtan Intercity Railway, the production process of steel reinforcement cage of shield segment lining and steel processing equipment system are systematically analyzed and studied; and then the design scheme and parameters of steel bar shearing, monolithic net forming, material storage and stereoscopic net welding and molding system module are determined; finally, the equipment manufacturing, engineering field application and optimization are completed, and an effective production line of segment reinforcement cage is formed. Thus the automatic and mechanized processing of steel reinforcement cage of shield segment lining is realized； the labor intensity is effectively reduced； the manufacturing security is improved, and the cage welding quality is controlled.
