Abstract

The invention discloses a buffer device for an elevator ceiling-hitting and ground-touching accident, and belongs to elevator safety buffer devices. Buffer device bodies are arranged at the bottom and the top of a running channel of an elevator cabin respectively. During elevator ground touching or elevator ceiling hitting, the impact force of the elevator cabin is relieved through the soft tension of extension springs; and the impact force is softly and gradually reduced through the soft resilience force of corner springs and the soft resilience force of center springs, and the safety state is achieved.

Description

technical field [0001] The present invention relates to Elevator manufacturing, especially elevator safety buffers. Background technique [0002] At present, in the elevator manufacturing industry, only one spring is used to prevent accidents at the bottom of the elevator, and there is no specific safety device at the top. With the development and improvement of the elevator manufacturing industry, the probability of accidents at the bottom and the top of the elevator is gradually reduced, but the reduction is not enough. It's like it won't happen. Contents of the invention [0003] In view of the above problems, the present invention provides a buffer device for accidents when the elevator goes to the top and squats to the bottom, which effectively resolves the problem of heavy casualties caused by the elevator squatting to the bottom and when the elevator goes to the top; the device has low investment and good safety guarantee. [0004] In order to solve the technical ...
