A Safety Gear is a mechanical device that stops the car (or counterweight) from moving. Safety gears are required for all passenger cars suspended by wire ropes or chains. When there is an extraordinary passage or space under the pit, a safety gear is also required for the counterweight. The safety clamps are placed on the lower beam of the car frame and act on the guide rails in pairs at the same time.
A speed limiter is a device that limits the speed of a car (or counterweight). Usually installed in the machine room or on the top of the hoistway. The tensioning device is placed in the pit.
The safety gear and the speed limiter must work together to function.
one. The speed limiter speed limiter can be divided into pendulum type and centrifugal type according to its action principle.
The hem pendulum speed limiter uses the cam on the sheave to contact the roller at one end of the pendulum during the rotation process. The frequency of the pendulum swing is related to the rotational speed of the sheave. When the vibration frequency of the pendulum exceeds a predetermined value, the pendulum The pawl of the hammer enters the stop pawl of the sheave, thereby stopping the speed limiter.
The Speed Governor of the centrifugal structure can be divided into two types: a vertical axis rotation type and a horizontal axis rotation type. The feature is simple structure, high reliability, and small space required for installation.
When designing or selecting, you should be aware of the following issues:
a. speed limiter speed
b. Pre-tensioning force of the speed limiter rope
c. Adhesion of the speed limiter rope in the sheave or tension of the speed limiter during operation
d. The response time of the speed limiter action should be as short as possible. The instantaneous safety gear is characterized by a short braking distance and a strong impact on the car.
Divided into several types:
Wedge type instantaneous safety gear eccentric block type instantaneous safety clamp roller type instantaneous safety gear three. The progressive safety clamp features a caliper elastic clamping type with a long stopping distance and a smooth car.
