AI Technical Summary
The existing single-beam structure of machine-room-less elevators generates vibration and noise problems during operation, especially during startup, shutdown, or operation, resulting in loud noise and severe resonance. Furthermore, the existing vibration reduction measures have limited effectiveness, especially when carrying heavy loads or operating for extended periods.
The structure adopts a double upper beam structure, which connects the first upper beam and the second upper beam by combining shock-absorbing rubber and shock-absorbing spring groups. Shock-absorbing rubber and shock-absorbing springs are set between the channel steels and designed as a "匚" shape to enhance stability. The shock-absorbing rubber and shock-absorbing spring groups absorb and buffer vibrations and impacts.
It effectively reduces noise and vibration during elevator operation, improves ride comfort, and enhances overall stability through a double upper beam structure, preventing debris from entering the car top wheel and facilitating maintenance work.
