Abstract

The invention relates to a circular pipe intersecting line marking device. The circular pipe intersecting line marking device comprises a slave pipe axis positioning structure, a main pipe axis positioning structure and a line marking execution structure, wherein the slave pipe axis positioning structure comprises an inner supporting frame, and at least two support legs used for being supported on the inner wall of a slave pipe are arranged on the outer side of the inner supporting frame; the main pipe axis positioning structure comprises a vertical rod, the bottom of the vertical rod is fixedly connected with the inner supporting frame, and a transverse round rod is fixedly arranged at the top of the vertical rod; the line marking execution structure comprises a movable sleeve, the movable sleeve is movably connected to the transverse round rod in a sliding and rotating sleeving mode, and a connecting rod is connected to the movable sleeve; and one end of the connecting rod is fixedly connected with the movable sleeve, and a line marking plate is fixedly arranged at the other end of the connecting rod. The circular pipe intersecting line marking device is simple in principle, easy to machine and convenient to operate, assemble and disassemble during use, and the construction efficiency can be remarkably improved. In long-term field use, the material processing cost is obviously reduced, and the circular pipe intersecting line marking device can be widely used for determining and processing the intersecting line of a steel pipe on the construction site.
