The rotating cylinder 214 will drive the second connecting rope 215, and the second connecting rope 215 will drive the second fixed ring 216 to move. The second fixed ring 216 will drive the first connecting rope 217 and the operating platform 2 to move up and down, thereby driving the operating platform 2 to move up and down, so that the staff can carry out construction at different positions on the surface of the square pier. The ladder-type construction mechanism and the lifting mechanism are combined to solve the technical problem of the traditional safe ladder-type construction structure of the square pier of the bridge. The support platforms are all built on the surface of the square pier. When the staff needs to carry out construction at other positions of the square pier, they need to build the operating platform 2 again, which is not very convenient.
