Main suspension cable oscillating motion preventing device of elevator

Abstract

Provided is an elevator main sling anti-swing device, which is respectively provided with a plurality of anti -sling swing bodies and brace tables, wherein the anti-sling swing bodies are overlapped on an upper part of an elevator car lifting along hoist trunk, the elevator main sling passes through the anti -sling swing bodies; the brace tables are arranged on one side of the hoist trunk, for supporting the anti -sling swing bodies at given position. The levator main sling anti-swing device is configured to set an interval size of the length direction of each anti -sling swing body to deflate from upper to lower, and the interval between the brace tables is set that the interval between the brace tables at the lowest part is larger than the width of the elevator car, but smaller than the interval of the length direction of the anti -sling swing bodies at the lowest part, while the interval between the brace tables at the upper part is larger than that of the length direction of the anti -sling swing bodies at the lower part of the brace tables, but smaller than that of the length direction supported by the brace tables.

Description

technical field [0001] The invention relates to an anti-swing device for a main sling for an elevator, which suppresses the swaying of the main sling due to an earthquake or the wind of an outdoor elevator. Background technique [0002] Generally speaking, in high-rise buildings, due to the use of the earthquake-resistant structure that the building itself displaces with the shaking of the earthquake, that is, the flexible structure, when an earthquake occurs, the lifting passage of the elevator and the elevators arranged along the lifting passage The main sling used to suspend the lifting body also sways. In addition, in outdoor elevators, especially elevators with a long lifting distance, the main sling will shake under the blowing of the wind. When the main sling shakes, it may come into contact with various equipment installed in the hoistway and cause the elevator to fail to operate normally. For this reason, an anti-swing device for the main sling for elevators that s...

AI Technical Summary

Problems solved by technology

[0007] In the above-mentioned prior art, the former anti-main rope sway device for elevators suppresses the sway of the main sling through a set of anti-main sling sway bodies and support platforms, but in recent years a large number of high-rise buildings with long lifting distances However, there is a problem that it is difficult to effectively suppress the shaking of the main sling

In addition, in the latter anti-swaying device for main ropes for elevators, a plurality of vibrating bodies for preventing main ropes are suspended by auxiliary ropes, and at the same time, an automatic wind-up device is additionally provided to prevent bending of the auxiliary ropes. However, due to the increase in parts of the equipment, there are problems in terms of installation cost and installation space
