Problems solved by technology
[0002] Considering the safety of the elevator, the elevator car is equipped with a safety braking device, which is mainly to ensure that the elevator can brake safely and stably when it stops, so as to prevent it from accidentally slipping and causing accidents. The braking devices currently used are all It is a sliding friction brake, which is essentially a rigid brake. Long-term use will cause brake failure due to wear and other conditions. The brake block needs to be repaired and replaced frequently. The safety brake effect is unstable, such as a car that prevents accidental movement. The brake protection device mentioned in the clamp wire rope protection device (application number 201120365619.4), if it is used for a long time, the brake nylon block will cause brake failure due to wear and tear, and the braking effect is unreliable

The invention discloses an elevator safety automatic control system. The system comprises a lift-down buffer brake device and a lift-up buffer brake device, wherein the lift-down buffer brake device and the lift-up buffer brake device are provided with a lift-down brake block assembly and a lift-up brake block assembly symmetric to two sides of a steel cable rope respectively; an electromagnetic coil connected with an elevator car control circuit is arranged on each of two sides of each of the lift-down brake block assembly and the lift-up brake block assembly; brake iron blocks capable of being magnetically adsorbed are arranged between the electromagnetic coils and the lift-down brake block assembly and between the electromagnetic coils and the lift-up brake block assembly; and brake springs are arranged between the brake iron blocks. According to the system, the braking is realized through braking rolling friction, a certain buffer effect is achieved, the braking effect can be improved, and the braking failure caused by wear can be prevented.
