Embodiment Construction

[0023] The invention discloses a buffer device for position limitation. The first fastening plate 1 is used to connect with the vibration-reducing and isolating device. Since the first fastening plate 1 and the top of the position-limiting seat have a position-limiting distance, the ship is Under the impact of waves or swinging in a maneuvering state, the power equipment installed with the vibration reduction and isolation device will shake in the direction of the limit seat; since the first fastening plate 1 is provided with a spherical groove on the side facing the limit seat, and the limit One end of the guide rod 16 is hemispherical, and one end of the limit guide rod 16 can passively slide and fit with the spherical groove. One end of bar 16 contacts, and one end of limit guide bar 16 can slide in the spherical groove; It will freely rotate and slide axially in the ball bearing to adapt to the shaking of power equipment equipped with vibration-reducing and isolating devic...

Abstract

The invention discloses a buffering device for limiting and belongs to the technical field of safety protection. The buffering device comprises a limiting base, a first fastening plate, a ball bearing, a limiting guide rod, an elastic support component, a cover plate, a first sleeve, a second fastening plate and a vibration isolation panel, wherein the first fastening plate is arranged right abovethe limiting base; the ball bearing is arranged in the middle of the top of the limiting base; one end of the limiting guide rod is semi-spherical; the other end of the limiting guide rod is connected with the limiting base through the elastic supporting component; a limiting distance is kept between the cover plate and the first fastening plate; two axial ends of the first sleeve are opened; thesecond fastening plate and the cover plate are respectively arranged at the two axial ends of the first sleeve to form a sealed cavity; and the vibration isolation panel comprises a carbon fiber bearing layer and a vibration isolation interlayer, so that a vibration isolation device can adapt to different working conditions when the limiting rigidity of the vibration isolation device is not changed. The reliability and the working efficiency of the buffering device are improved. The limiting guide can be protected.

Description

technical field [0001] The invention belongs to the technical field of shock absorption, and in particular relates to a buffer device for position limiting. Background technique [0002] Vibration and noise reduction on ships has been paid more and more attention by people. The power equipment on ships basically adopts vibration reduction and isolation technology, including single-layer vibration isolation, double-layer vibration isolation and large-scale floating raft vibration reduction, which can effectively reduce the vibration of power equipment from being transmitted to the supporting platform or hull structure, and improve The comfort of the ship's staff can also improve the sound concealment of the ship and enhance the combat capability of the ship. [0003] When the ship is under the impact of waves or maneuvering, the power equipment will have a large displacement after the power equipment is equipped with a vibration reduction device. In order to ensure that ther...
