Embodiment Construction

[0024] The invention discloses an impedance device for position limiting. 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 dev...

Abstract

The invention discloses a resisting device for limiting and belongs to the technical field of safety protection. The resisting device comprises a limiting seat, a first fastening plate, a ball bearing, a limiting guiding rod, an elastic supporting assembly, a cover plate, a first sleeve, a second fastening plate and a resisting mechanism. The first fastening plate is arranged over the limiting seat, and the ball bearing is arranged in the middle of the top of the limiting seat. One end of the limiting guiding rod is hemispherical. The other end of the limiting guiding rod is connected with thelimiting seat through the elastic supporting assembly. The cover plate and the first fastening plate have the limiting distances, and the two axial ends of the first sleeve are open. The resisting mechanism comprises a base structure main body which is constituted by a fixing web, an equipment public mounting face plate and fixing supporting toggle plates, wherein the fixing web and the equipmentpublic mounting face plate are vertically connected, and the fixing supporting toggle plates are evenly arranged between the fixing web and the equipment public mounting face plate; and thus the technical effect that the vibration reduction and isolation effects of a vibration reduction and isolation device is improved, so that damage to a ship body is avoided is achieved.

Description

technical field [0001] The invention belongs to the technical field of shock absorption, and in particular relates to an impedance 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 ...
