Description

A rotating waist ring that follows the rotation of the tower. Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically to a rotating waist ring that follows the rotation of the tower body. Background Technology

[0002] With the rapid development of my country's power construction, the number of power grid lines is constantly increasing, leading to a surge in demand for power construction machinery. The tower erection environment is becoming increasingly complex, with mountainous areas, hills, plateaus, and muddy terrain causing difficulties in the transportation and erection of gantry cranes. Currently, the double-rocker-arm ground-mounted gantry cranes used for tower erection offer high safety, but they occupy a large area, are heavy, and are difficult to transport. For multi-component assembly and transportation, large lifting equipment is necessary; however, in steep slopes or muddy environments, where large lifting equipment is unavailable, components must be disassembled and carried by hand, resulting in a massive workload and being extremely time-consuming and labor-intensive. To address these industry challenges, an integrated bottom-lifting and bottom-slewing gantry crane design was developed. However, the original power gantry cranes were top-slewing, requiring no tower rotation, and therefore no rotation of the waist ring. The current development of bottom-slewing gantry cranes addresses the issue that the waist ring design of the original top-slewing gantry cranes cannot meet the requirements for overall tower rotation. Summary of the Invention

[0003] To solve the above technical problems, this utility model provides a rotating waist ring that follows the rotation of the tower body. The inner waist ring can rotate synchronously with the tower body inside the outer waist ring, ensuring the stability of the tower body at all times.
