Abstract: The present application describes a bridge sliding device and construction system. The device includes a slide rail assembly, a first sliding component on the rail, and a second sliding component on the first. The second component locks at the start of the first, and the bridge deck truss's weight causes the first component's end to tilt slightly, allowing it to easily cross the junction between the temporary support platform and the bridge pier. This facilitates the smooth crossing of both the first and second components over the junction. Once the first sliding component is in place, the second component unlocks and continues sliding, increasing the travel distance of the bridge deck truss. The system ensures smoother movement of the components, enhancing construction efficiency.

Abstract: The present application describes an intelligent hoisting method for a bridge deck crane system. The method involves determining the splicing heights at two key positions of the segment to be installed by measuring the alignment height of an already installed segment. The segment is hoisted, and the real-time heights at both positions are monitored. If one position reaches the splicing height while the other does not, the lifting point is adjusted until both positions align with their respective splicing heights. This method eliminates the need for reference marks or docking joints on the segment to be installed, thereby avoiding issues related to their precision and installation accuracy. Additionally, it simplifies the splicing operation by removing the need for pre-processing the segment, reducing the overall complexity of the process.
