Problems solved by technology

[0003]However, the existing pipeline vibration damping devices mostly use fixed support structures for vibration damping, resulting in excessive vibration of the suspended part of the infusion pipeline and poor vibration damping effect , and the space volume of the support structure itself is relatively large, for some pipelines located in a narrow space, the vibration damping ability cannot be fully exerted, thereby affecting the service life of the infusion pipeline, and also affecting the stealth performance of some special equipment, which is far from satisfying The demand for vibration reduction in production and transportation

Embodiment 1

[0029] like Figure 1~4 As shown, a self-adjusting ship pipeline vibration damping device in this embodiment includes a clamp 7 and four slide rail assemblies installed on the outside of the clamp, and the linear slide rail assemblies are evenly installed on the outside of the clamp; along x Two slide rail assemblies are arranged in the axial direction, respectively located on the left and right sides of the hoop, and two slide rail assemblies are arranged along the y-axis direction, respectively located on the upper and lower sides of the hoop. The hoop 7 is ring-shaped as a whole, and there are fastening bolts 6 for fixing on both sides, so that the hoop is fixed on the pipeline; the slide rail assembly includes the outer guide rail 4, the inner slide rail 1 and the spring 3, and the outer guide rail 4 is fixed on the clamp Outside the hoop 7, the two ends of the spring are fixedly connected with the outer guide rail and the inner slide rail respectively, and the outer guide...

Embodiment 2

[0039] like Image 6As shown, on the basis of Embodiment 1, the damping device in this embodiment is provided with a traction piece 10 between two adjacent slide rail assemblies, and one end of the traction piece 10 is fixedly connected to the outer guide rail on one side, The other end of the traction piece is fixedly connected with the outer guide rail on the other side, and the damping blocks on two adjacent slide rail assemblies are arranged oppositely; and the traction piece is made of spring steel. in, Image 6 Schematic representation only, details not shown in figure 1 unanimous.

[0040] When observing the motion state of the device, it is found that the motion direction of the vibration-damping blocks on the same side is not synchronized, making the motion of the vibration-damping blocks on the same side relatively synchronous.

[0041] The vibration damping effect of the vibration damping device in this embodiment is shown in Table 1 below.

Abstract

The invention discloses a self-adjusting ship pipeline damping device and a damping method thereof. The self-adjusting ship pipeline damping device comprises a hoop and a sliding rail assembly installed on the outer side of the hoop, the sliding rail assembly comprises an outer guide rail, an inner sliding rail and a spring, the outer guide rail is fixed to the outer side of the hoop, the two ends of the spring are fixedly connected with the outer guide rail and the inner sliding rail correspondingly, and the outer guide rail is in sliding fit with the inner sliding rail. According to the self-adjusting ship pipeline damping device, the damping effect of the pipeline, especially the suspension part, can be improved; and the damping device is remarkable in damping effect, the defect that the vibration load of the suspended part of a liquid conveying pipeline is too large is overcome, the safety of the damping device is greatly improved, the service life of the damping device is greatly prolonged, and the damping device has good application prospects in the future.

Description

technical field [0001] The invention relates to pipeline vibration damping equipment, in particular to a ship pipeline vibration damping device and a vibration damping method. Background technique [0002] At present, ship transportation is more and more frequent, and there are many piping systems in ships, such as cooling piping systems, power piping systems, and liquid cargo transportation piping systems. However, the turbines, propellers and other devices of the ship in use will generate a lot of vibration, and it is necessary to cooperate with the vibration damping device to prevent the vibration from affecting the working state of the piping system. [0003] However, the existing pipeline vibration damping devices mostly use fixed support structures for vibration reduction, resulting in excessive vibration of the suspended part of the infusion pipeline and poor vibration damping effect, and the space volume of the support structure itself is relatively large. The pipel...
