Description

Technical Field

[0001] This utility model belongs to the field of elevator wire rope, specifically, it relates to an anti-sway device for elevator wire rope. Background Technology

[0002] During elevator operation, the lack of auxiliary stabilizing points makes it prone to swaying within the shaft. As the elevator's lifting height and speed increase, air turbulence further exacerbates the swaying. Speed ​​governors are typically used to reduce the amplitude of the wire rope swaying.

[0003] Patent application CN206051217U discloses an elevator wire rope anti-sway device. Paragraph 0080 of the specification describes an elevator shaft connector comprising a right-angled bent plate and a right-angled bent plate fixedly connected by bolts. A nut is welded to the dustproof plate. The side of the right-angled bent plate is fixedly connected to the dustproof plate by bolts that mate with the nut. The side of the right-angled bent plate and the side of the right-angled bent plate are abutted against each other and fixedly connected by bolts. The side and the side of the right-angled bent plate are provided with slotted holes for the bolts to pass through, and the extending directions of the two slotted holes are parallel to each other.

[0004] However, in practical applications, although the amplitude of wire rope swaying can be reduced by the guide hole on one side of the fixed plate, the gap formed between the two fixed plates can easily aggravate the amplitude of wire rope swaying, which may cause the speed governor to malfunction and affect elevator safety in severe cases.

[0005] To address this issue, an anti-sway device for elevator wire ropes is proposed. Utility Model Content
