[0028] In use, the hollow ground roller assembly 1 is placed below the steel wire rope, and the steel wire rope is located at the middle position between the two support plates 11. After the steel wire rope is pulled out and moves to the solid ground roller assembly 2 through the hollow ground roller assembly 1, the steel pipe 13 can support the steel wire rope and prevent the steel wire rope from deviating.

[0029] In the embodiment, the steel pipe 13 and the first round steel 14 are connected by a bearing 15, that is, the bearing 15 is welded and fixed on the first steel pipe 13.
