[0002] With the development of crane technology, cranes with large lifting heights mostly use fence-type multi-layer winding drums. This structural form has high requirements on the drum processing accuracy and wire rope diameter deviation. It is often the case that the multi-layer winding wire rope is replaced due to the non-standard opening size accuracy of the drum baffle or the diameter deviation of the new wire rope, or the rope jumps too early or too late at the baffle, causing the rope to be tangled.

[0003] When encountering the above situation, it is necessary to manually grind the roll baffle until the opening size between the baffles meets the requirements; or first weld the baffle and then grind it. However, this working method has a large workload and high difficulty in rectification. In addition, due to the limited working space at the roll position, it is not convenient for the staff to carry out work at the same time, and the overall process is time-consuming.

[0009] As a further implementation, the positioning baffle is a circular ring structure, and the movable baffle is arranged on the peripheral side of the positioning baffle.

[0010] As a further implementation, a set gap is left between the movable baffle and the positioning baffle.

[0032] In order to fix the horizontal position of the fence-type rope groove housing 2 on the drum 1, a positioning baffle 4 is welded on the inner side of the fixed baffle 3, and the positioning baffle 4 is also welded on the outer side of the drum 1. Figure 4 As shown, the positioning baffle 4 is a circular ring structure, and the outer diameter of the positioning baffle 4 is adapted to the outer diameter of the fence-type rope groove housing 2.

[0034] Specifically, the movable baffle 5 is arranged on the peripheral side of the positioning baffle 4, and a set gap is left between the movable baffle 5 and the positioning baffle 4, so that the fence-type rope groove housing 2 does not contact the movable baffle 5, which is convenient for disassembly of the movable baffle 5 and does not affect the winding of the wire rope.

[0035] The outer diameter of the movable baffle 5 of this embodiment is matched with the outer diameter of the fixed baffle 3. When the movable baffle 5 is installed inside the fixed baffle 3, the distance between the movable baffles 5 is the opening size L.
