AI Technical Summary

⚠Technical Problem

The existing elevator compensation chain cannot effectively limit movement during use, resulting in significant swaying during operation, affecting balance and generating noise.

⚗Method used

The design includes a limiting and anti-vibration structure, which includes a limiting roller and a buffer mechanism. The limiting roller rotates through a fixed shaft in the fixed block and is fitted with a protective sleeve made of silicone or rubber to reduce friction noise. The buffer mechanism absorbs vibration force through a connecting rod, piston and nitrogen to reduce oscillation.

🎯Benefits of technology

It effectively avoids the swaying and noise of the compensation chain, improves the smoothness of movement, reduces friction noise and absorbs vibration, and enhances the stability and safety of elevator operation.

Abstract

This utility model relates to the field of elevator compensation chain technology, specifically disclosing an elevator compensation chain with a limiting and anti-vibration structure. It includes a compensation chain body, a fixing plate welded to the upper surface of the compensation chain body, a limiting mechanism for limiting the chain's movement on the outside of the compensation chain body, and a buffer mechanism for cushioning the chain above the fixing plate. The limiting mechanism includes four limiting rollers symmetrically arranged on the outside of the compensation chain body. Through the limiting mechanism, the limiting rollers can limit the movement of the compensation chain body. A fixed shaft within the fixing block allows the limiting rollers to rotate, ensuring smooth movement of the compensation chain body. Furthermore, the protective sleeves on the outer surfaces of the limiting rollers are made of silicone or rubber, providing protection and reducing noise generated when the compensation chain body rubs against the limiting rollers.
