AI Technical Summary
In existing freight elevators, the accumulation of sludge in the traction rope grooves leads to unstable friction coefficients, increases energy consumption and mechanical wear of the traction system, and manual cleaning is cumbersome and cannot be achieved in real time.
Design a high-efficiency and energy-saving freight elevator, which adopts a scraper frame and scraper block structure. The scraper blocks made of polyurethane material are matched with the traction sheave rope groove. The intermittent contact between the scraper blocks and the rope groove is controlled by an electric telescopic rod. Combined with a U-shaped oil-absorbing felt and a collection box, the automatic scraping and collection of oil sludge is realized.
Effectively maintaining the friction coefficient between the traction sheave and the rope groove within the design range reduces elevator operating energy consumption, minimizes mechanical wear, avoids tedious manual cleaning operations, and achieves automated and convenient sludge management.
