Abstract

PURPOSE:To prevent the shaking of a cage at the time of getting on and off by making rollers installed on a cage guide while leaving a space toward a guide rail during the traveling of the cage and expanding the rollers while bringing same into contact with the guide rail when the cage is stopped. CONSTITUTION:Three guide rollers 4A-4C are rotatably installed by each rotary shaft 5 on a supporting member 3 installed on a cage 2, to guide the cage 2 by means of a guide rail 1 provided on a lifting up/down passage. During the traveling of the cage 2, the guide rail 1 and the guide rollers 4A-4C guide the cage 2 while leaving a proper interval. As the cage 2 is stopped, the damping pieces 9 of the guide rollers 4A-4C are electrified and expanded to be brought into pressure contact with the supporting member 3 of the guide rollers 4A-4C, to prevent the shaking of the cage 2. Thereby, the shaking of the cage while getting on and off can be prevented to give a good ride.

In general, low-speed elevators use guide shoes that slide on guide rails to guide the car up and down, while medium and high-speed elevators use roller guides that roll on guide rails to guide the car. It is being This is because when a guide shoe is used, vibrations caused by steps or unevenness in the guide rail become impossible to ignore as the speed increases, and running loss due to vibration resistance increases.
