Embodiment 1

[0038] The invention provides a multi-layer vibration isolation and anti-shock pipeline support, see the attached figure 1 , including: upper clamp 1, damping ring 2, lower clamp 3, upper vibration isolator 4, intermediate mass 5, lower vibration isolator 6, limit block 7 and limit pin 8;

[0039] See attached figure 2 , the upper clamp 1 is a U-shaped structure with a square cross section, and the two ends of the U-shaped structure are provided with external threads;

[0040] The damping ring 2 is a split structure;

[0041] See attached image 3 , 4 , the lower clamp 3 is composed of a strip plate and a boss, and the strip plate has a plurality of through holes, wherein the through hole located in the middle of the strip plate is a limiting hole, and the through holes at both ends are installation holes ; The upper surface of the boss is an arc surface, and the lower surface has a groove; the boss is fixed on the strip plate, and the groove on the lower surface of the b...

Embodiment 2

[0055] On the basis of Embodiment 1, the vibration-damping ring 2 is made of a rubber pad or a vibration-isolation belt. The vibration-isolation belt has excellent vibration-isolation performance and improves environmental adaptability.

Embodiment 3

[0057] On the basis of Embodiment 1 or 2, the clamp on the square section can be changed to the clamp on the cylindrical section, which is easier to process for the U-shaped structure.

Abstract

The invention discloses a multi-layer vibration isolation and impact prevention pipeline support, and belongs to the technical field of vibration noise control. The multi-layer vibration isolation and impact prevention pipeline support comprises an upper clamp, a vibration reduction ring, a lower clamp, upper layer vibration isolators, a middle mass block and lower layer vibration isolators. The two or more lower layer vibration isolators are fixed to the lower surfaces of the non-inward-concave portions of the two ends of the middle mass block respectively. Bases of the two or more upper layer vibration isolators are fixed to the upper surface of an inward-concave cavity of the middle mass block. A strip-shaped plate of the lower clamp is fixed to the top ends of the upper layer vibration isolators. A limiting hole of the lower clamp is in hole shaft fit with a limiting pin fixed to the connecting plate of the middle mass block to limit the lower clamp. The two ends of the upper clamp are fixed to the strip-shaped plate of the lower clamp. The vibration reduction ring is installed between bosses of the upper clamp and the lower clamp. The pipeline support has the functions of high efficiency, vibration reduction, impact prevention and adjustment, and the vibration reduction effect of the pipeline support can be effectively improved; meanwhile, the limiting function is achieved on the impact working condition, the structure is compact, and adjustment, disassembly and assembly are convenient.

Description

technical field [0001] The invention belongs to the technical field of vibration and noise control, and in particular relates to a multi-layer vibration isolation and anti-shock pipeline support. Background technique [0002] With the application of vibration isolation devices such as floating rafts, the vibration transmitted by the first channel (equipment-base-hull) is getting smaller and smaller, and the second channel (equipment-pipeline-support-hull) has gradually become a short board for vibration control . Reducing the vibration of the second channel is of great significance for improving the stealth performance of the ship. [0003] The application of vibration isolation brackets is the main way of pipeline vibration isolation, and the current vibration isolation brackets are all single-layer vibration isolation; moreover, in order to cope with shock, swing and other working conditions, the stiffness of the vibration isolator selected is usually much higher than Vi...
