Description

Installation method of anti-vibration device for elevator suspension rod

technical field

The invention relates to an installation method of an elevator suspension rod anti-vibration device. In the elevator, the sling connected to the elevator car and the counterweight is supported by a support beam erected on the upper part of the elevator passage through the suspension pulley and the suspension rod. , wherein the suspension rod anti-vibration device is used to reduce the vibration transmitted from the suspension rod to the support beam.

Background technique

There are many elevators that adopt the following structure: a support beam is provided on the upper end side of the guide rail for the elevator car that guides the elevator car to move up and down, and the guide rail for the counterweight that guides the counterweight to move up and down, and is supported by the suspension pulley and the suspension rod. Beams to support the slings attached to the elevator car and counterweights. Therefore, the vibration generated by the lifting and lowering motion of the elevator car and the counterweight is transmitted to the support beam through the suspension rod. The vibration is further transmitted from the support beam to the guide rail, and from the guide rail to the building through the guide rail bracket, especially when the room of the resident is relatively close to the hoistway of the elevator, the resident will be disturbed by the noise. Therefore, it is necessary to prevent the vibration from being transmitted from the suspension rod to the support beam as much as possible. For this reason, a solution has been proposed in the prior art. For example, an elastic body is provided at the connecting part of the support beam supporting the suspension pulley and the suspension rod used for suspending the suspension pulley, so as to reduce the transmission to the support. Vibration of beams and buildings (for example, refer to Patent Document 1 and Patent Document 2).
