Villa elevator overspeed governor

Technical Field

The utility model relates to the technical field of elevator parts, in particular to a villa elevator speed limiter.

Background

An elevator speed limiter is one of safety control components in an elevator safety protection system. When the elevator overspeed the elevator car and even falls for whatever reason during operation, and all other safety protection devices are not active, the speed limiter and the safety tongs act in a linkage manner, so that the elevator car is stopped. The existing speed reducer can be embedded with the side face of a ratchet wheel, but has potential safety hazards of fracture in compression test and long-term use.

Therefore, in the chinese patent publication No. CN217535081U, an elevator speed limiter is proposed, and the speed reducer pushes the linkage rod through the electromagnet, so that the ratchet wheel and the pawl are matched and brake under the action of the boss, thereby increasing the braking strength and eliminating the potential safety hazard of pawl fracture.

However, when the speed limiter rope wheel in the speed limiter works to shake, the braking on the rope is easy to influence, and meanwhile, when the speed limiter rope wheel works, the shake rope can also influence the speed limiter rope wheel to perform speed reduction, so that certain potential safety hazards exist.
