Steel-structural wire frame travelling crane lifting point structure

The utility model relates to a steel-structural wire frame travelling crane lifting point structure for connecting a wire frame sphere and a travelling crane rail beam. The steel-structural wire frame travelling crane lifting point structure comprises an end plate structure, a vertical lifting rod and a converting supporting seat, wherein the end plate structure is fixedly connected to the top of the travelling crane rail beam; the vertical lifting rod is fixedly connected to the top of the end plate structure; the first end of the converting supporting seat is fixedly connected to the top of the vertical lifting rod, the second end of the converting supporting seat is fixedly connected to the bottom of the wire frame sphere, and a spherical surface which corresponds to the outer surface of the wire frame sphere is formed on the second end of the converting supporting seat. According to the steel-structural wire frame travelling crane lifting point structure, the position deviation of the travelling crane rail beam is eliminated by regulating the connecting position of the converting supporting seat and the vertical lifting rod; the spherical surface formed on the second end of the converting supporting seat supports against the bottom of the wire frame sphere, so that the plane deviation generated by the wire frame sphere in the installation process of the wire frame sphere is eliminated by regulating the shape and position of the spherical surface, the lifting point is positioned on an ideal theoretical plane position by effectively regulating the installation position of the travelling crane lifting point, the installation accuracy of the lifting point is ensured, and the requirement for installation of the travelling crane lifting point and the travelling crane rail beam is met.
