AI Technical Summary
During use, the high friction between the overhead crane wire rope and the steel pole during sliding contact can lead to damage to the wire rope and the limit structure, thus affecting the efficiency of crane operation.
A gyratory wire rope limiting structure was designed, which uses a sleeve and nut connector. The sleeve is rotatably engaged with the connecting rod. The thickness of the nut is smaller than the diameter of the wire rope to avoid jamming. Reinforcing ribs are set on the inner wall of the sleeve to improve stability.
This achieves smooth vertical movement of the wire rope, reduces friction damage, and extends the service life of the wire rope and the gyroscope limit structure.

[0010] In the above-mentioned scheme, as a preferred, the thickness of the nut is less than the diameter of the steel wire rope.
[0011] In the above-mentioned scheme, as a preferred, the sleeve inner wall has several reinforcing ribs distributed in the circumferential direction, the length direction of the reinforcing rib is the axial direction of the sleeve, and the distance between the adjacent two reinforcing ribs is less than 1 / 2 of the radius of the corresponding first connecting rod and third connecting rod.
[0012] Compared with the prior art, the utility model has the advantages of:
[0013] Through the design of the sleeve, the steel wire rope is smooth and does not block when moving up and down.
[0014] The sleeve is preferably a stainless steel sleeve, which has high strength and long service life.
[0015] The thickness of the nut is less than the diameter of the steel wire rope, so that the steel wire rope is prevented from being clamped between the gasket and the top body. BRIEF DESCRIPTION OF DRAWINGS
