Description

A U-shaped seismic isolation metal hose with all-round large displacement compensation

Technical Field

The utility model relates to the technical field of seismic isolation flexible pipelines, in particular to an all-round large displacement compensation U-shaped seismic isolation metal hose.

Background Art

Pipeline seismic isolation is a method of separating pipelines from building structures or foundations through the use of specific designs and technical means to reduce or isolate the impact of external forces such as earthquakes and mechanical vibrations on the pipeline system. This technology is designed to protect pipelines from damage, ensure the safe and stable operation of the pipeline system, while reducing the spread of vibration and noise, and improving the overall reliability and service life of the system. Pipeline seismic isolation technology is widely used in various fields, such as petrochemicals, transportation, energy supply, etc., and is of great significance to ensuring the normal operation of pipeline systems and environmental protection.

The existing Chinese patent with announcement number CN216743319U discloses a U-shaped seismic isolation metal hose with all-round large displacement compensation. In view of the problem that the existing seismic isolation flexible pipe technology requires the displacement compensation direction of the flexible part to be arbitrary and the displacement compensation amount to be large, the following scheme is proposed, which includes a retractable pipe, both ends of the retractable pipe are provided with flanges, and the flanges can be used to connect with the external pipe, and the outer side of the retractable pipe is provided with a deformation constraint mechanism. The deformation constraint mechanism includes multiple groups of hinge plates, and the number of hinge plates in a group is composed of multiple hinge plates, and the multiple hinge plates in each group are rotatably connected at one end close to each other. The utility model effectively controls the installation or displacement deformation by combining the metal hose and the deformation constraint mechanism, thereby improving the safety and fatigue life of the pipeline system. It has a simple structure, reliable performance, and substantial characteristics, filling a gap in the displacement compensation products of building seismic isolation pipes.

The above scheme and the pipe seismic isolation technology under the existing technology can only meet the preset displacement in a single direction. However, the displacement direction of an earthquake may be complex and changeable, and single-direction seismic isolation often cannot achieve good results. There is a lack of corresponding structure here, and improvement and optimization are needed.

Tight connection ensures the integrity and sealing of the pipeline system. The flange 1 is provided with mounting holes 9. The number of mounting holes 9 is set to four and arranged in a circular array on the flange 1. A clamp 3 is sleeved on the circumferential surface of the U-shaped metal hose 2 to fix and strengthen the U-shaped metal hose 2 to ensure that it will not be excessively deformed or damaged when subjected to external force. The tight wrapping and fixing effect of the clamp 3 provides additional support and protection for the U-shaped metal hose 2. The number of clamps 3 is set to multiple, and a fixing plate 4 is fixedly connected to the circumferential surface of the clamp 3. The number of fixing plates 4 on the clamp 3 is set to four and arranged in a circular array on the circumferential surface of the clamp 3. The combination of the clamp 3 and the fixing plate 4 provides additional support and protection for the U-shaped metal hose 2 to prevent it from being excessively deformed or damaged due to external force, and at the same time meets the expansion and contraction requirements of the U-shaped metal hose 2 in different directions, ensuring that the U-shaped metal hose 2 can be evenly stressed in all directions.

The deformation restraining mechanism 5 comprises a hinge plate 6, a slide groove 7 and a pin 8. There are multiple hinge plates 6, and two hinge plates 6 are set as a group. The two hinge plates 6 are rotatably connected by the pin 8. The slide groove 7 is arranged inside the hinge plate 6, and the pin 8 is slidably connected with the slide groove 7. The hinge plates 6 close to each other between the two deformation restraining mechanisms 5 are rotatably connected by the fixed plate 4, and the fixed plate 4 is slidably connected with the slide groove 7.

The deformation restraining mechanism 5 is symmetrical with respect to the U-shaped metal hose 2 , and the deformation restraining mechanisms 5 on the same side are perpendicular to each other, and the pin shaft 8 and the hinge plate 6 on the fixing plate 4 are staggeredly connected.

In actual use, the deformation constraint mechanism 5 limits the deformation direction of the U-shaped metal hose 2 through the combined design of the hinge plate 6, the slide groove 7 and the pin shaft 8, and provides necessary displacement compensation. The deformation constraint mechanism 5 can ensure that the U-shaped metal hose 2 can be displaced according to the predetermined path when subjected to external force, thereby protecting the safe and stable operation of the pipeline system. The deformation constraint mechanism 5 can flexibly adapt to displacement changes in different directions and sizes. Its left-right symmetry and vertical staggered design enable the U-shaped metal hose 2 to be evenly supported and constrained in all directions, thereby improving the stability and reliability of the entire system. At the same time, the sliding connection design of the pin shaft 7 and the slide groove 8 enables the deformation constraint mechanism 5 to have certain adjustability and flexibility to adapt to different installation environments and displacement requirements.
