AI Technical Summary
When the existing centrifugal speed governor is running in the downward and upward directions, the sequence of remote-triggered electrical actions and mechanical actions is inconsistent, which makes elevator maintenance and acceptance difficult, and there is a risk that the electrical path will be formed before the mechanical action is reset.
A remote-controlled triggered centrifugal speed limiter four-bar linkage mechanism was designed, including a ratchet component, a rope wheel assembly, a support assembly, a switch assembly, an electromagnet assembly, and a protective cover. By combining the mechanical action of the ratchet and rope wheel with the electrical action of the electromagnet, the electrical action is ensured to take precedence over or be synchronized with the mechanical action, preventing the formation of an electrical path before the mechanical action is reset.
This technology ensures that the remote-controlled electrical action sequence of the centrifugal speed governor is consistent in both the upward and downward directions, simplifying the elevator maintenance and acceptance process, improving safety, and preventing the risk of electrical path failure before mechanical action reset.
