[0002] With the acceleration of China's economic development and urban construction, there are more and more super-large and super-high buildings over 10 meters. There are also various movable partitions for super-large and super-high buildings in the construction market. Due to their large volume and heavy weight, super-high movable partitions are often installed and used in cooperation with hanging wheels during installation or use. The hanging wheels can effectively disperse the weight of the movable partition, reduce the direct pressure on the ground or wall, and ensure the stability and safety of the partition structure.

The lead screw 2 is a hollow structure, and a safety steel cable 3 passes through the hollow structure of the lead screw 2. The length of the safety steel cable 3 is greater than the length of the lead screw 2. The upper end of the safety steel cable 3 is limited to the upper end face of the hanging wheel main body 1 through the first limit assembly, and a second limit assembly is provided at the lower end of the safety steel cable 3.

By setting the first nut, the upper end of the safety steel cable can be limited.

[0034] As Figure 1 and Figure 3 shown, a further preferred solution in this embodiment is that the first limit assembly further includes a first limit block 5. The first limit block 5 is located between the first nut 4 and the upper end face of the hanging wheel main body 1. The safety steel cable 3 passes through the first limit block 5. The first limit block 5 is a cube structure, and the outer diameter of the first nut 4 is not greater than the side length of the first limit block 5.
