AI Technical Summary

Technical Problem

The existing slewing bearings of aerial work platforms are difficult to lock automatically when power is interrupted, causing the platform to rotate freely. In addition, the motor has poor heat dissipation, which affects safety and service life.

Method used

A rotary drive bearing including a self-locking mechanism and a cooling mechanism was designed. The self-locking mechanism achieves automatic locking through the linkage of an electric telescopic rod and a slider, while the cooling mechanism dissipates heat through a temperature sensor and a fan.

Benefits of technology

It achieves automatic locking of the slewing bearing when power is interrupted, improving safety, preventing accidents, and extending the service life of the motor and reducer through effective heat dissipation.
