Description

technical field [0001] The invention relates to a segment assembly machine in the technical field of engineering machinery, in particular to a six-degree-of-freedom shield segment assembly machine. Background technique [0002] The segment assembly machine is one of the important parts of the shield tunneling machine used in tunnel construction. After the shield tunneling machine advances forward, it must assemble the tunnel lining with prefabricated reinforced concrete segments to protect the excavated tunnel surface. . The quality of segment assembly directly affects the penetration of underground water and soil and the settlement of the ground surface, and the function of the shield segment assembly machine responsible for completing segment assembly has an important impact on the quality of segment assembly and the progress of tunnel construction. [0003] After searching the existing relevant technical documents, it is found that the Chinese patent application number i...

Problems solved by technology

Since the device only relies on the segment tilting cylinder and the segment rotating cylinder to realize the swing of the segment, and relies on the lifting cylinder to realize the up and down lifting and left and right micro-movement of the segment, so the loads of the segment tilting cylinder, segment rotating cylinder and lifting cylinder are relatively heavy. Large, the overall load capacity of the mechanism is low; in addition, the device is essentially composed of a two-degree-of-freedom series mechanism, a two-degree-of-freedom plane moving parallel mechanism and a two-degree-of-freedom rotating parallel mechanism in series, and there are many accumulated errors , the overall low stiffness of the mechanism is not conducive to the control of the segment assembly machine and the long-term, high-load work
