Abstract

The invention discloses an elevator overspeed protection device. The device drives a centrifugal box to rotate through a guiding wheel, and when an elevator car overspeeds, a centrifugal force machineis used for triggering a locking unit to act on a speed reduction rail, and the car is decelerated or stopped; through the arrangement of the independent guiding wheel and a guiding rail, the car ismore stable during braking deceleration, and car swinging due to uneven stress is avoided; according to the device, introduction of an electronic element is avoided, control is conducted through mechanical transmission, and insecurity of the electronic element is avoided; and meanwhile, triggering is rapid and sensitive, and a good braking effect is achieved.

Description

technical field

[0001] The invention relates to the technical field of elevators, in particular to an elevator overspeed protection device. Background technique

[0002] With the continuous and rapid development of society, the use of elevators is becoming more and more popular in people's lives. However, the safety hazards of elevators are still a concern for everyone, especially the problem of elevator overspeed. The loss of control of the machine, counterweight and braking system often causes the overspeed operation of the elevator, which brings great hidden dangers to people's personal safety. Contents of the invention

[0003] The object of the present invention is to address the above-mentioned deficiencies in the prior art, and propose an elevator overspeed protection device, which can automatically trigger the locking unit to act on the track when the elevator car is running overspeed, so as to slow down or stop the car.

[0004] An elevator overspeed protection d...
