AI Technical Summary
The brakes in existing elevator traction drive devices cannot adjust the pressure after the friction pads wear down, resulting in unstable braking performance and affecting safety.
An adjustment component was designed, which uses an electromagnet to drive a limit block to move on a connecting rod, thereby adjusting the tension of the spring and thus adjusting the pressure of the connecting parts. Combined with a buffer pad, it reduces the contact pressure after the friction plate wears.
It improves braking stability and safety, avoids the situation where the friction pads cannot effectively contact the brake wheel after wear, and enhances the braking effect.
