Special elevator anti-drop buffer based on flexible guide

摘要

-8 Abstract A special elevator anti-drop buffer based on flexible guide, which is used for connecting and fixing the end portion of a brake steel wire rope of an elevator, and comprises an upper support plate and a lower support plate, wherein a pulley block is arranged on the upper support plate and the lower support plate, and hydraulic damping buffers are arranged at the two sides of the pulley block. The anti-drop buffer adopts the energy consumption principle of hydraulic damping holes, the brake steel wire rope is protected from being impacted by the elevator, meanwhile, the impact caused by a spring on the elevator after braking is prevented, and the safety and reliability performance of the elevator braking can be improved, so the safety performance of a special elevator is effectively improved. In addition, with the pulley block utilized in the special elevator anti-drop buffer, the braking length of the brake steel wire rope can be increased, so the service life of the steel wire rope can be prolonged.
