Background

With the continuous improvement of the technical level of ships and the continuous deepening of understanding of vibration noise, the vibration reduction and noise reduction design work is more and more emphasized, and the vibration transmission from ship noise source equipment to a machine leg can be efficiently isolated by utilizing the air bag vibration isolator, so that a good vibration isolation effect is achieved.

The existing airbag vibration isolator needs to be installed in a special protection tool in the transportation process so as to prevent the airbag from being damaged in the transportation process; after the air bag is transported to a use site, a special supporting block is needed to support an upper cover plate and a lower cover plate of the air bag vibration isolator, and equipment needing vibration reduction is installed on the upper cover plate of the air bag vibration isolator after the air bag is supported; after the equipment is installed, the air bag is inflated, and the supporting block can automatically fall off due to the expansion of the air bag during inflation.

In the actual transportation and use process, the condition that a protection tool or an external support part is lost often occurs, the transportation or installation progress of the air bag shock absorber is influenced, and the wide application of the air bag shock absorber is limited to a certain extent. In addition, when the air bag vibration isolator is used, if the air bag is suddenly damaged, the upper cover plate can fall down, and equipment installed on the air bag vibration isolator can be damaged.
