[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0030] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Please refer to Figure 1-9 , the present invention provides a technical solution: a sleeve assembly for seismic resistance of pipelines used in municipal engineering of the present invention includes an upper sleeve ring 1 and a lower sleeve ring 2. The upper sleeve ring 1 and the lower sleeve ring 2 are detachably connected through a locking member 3. A hoisting structure 4 is connected above the upper sleeve ring 1, and a fixing structure 5 is connected below the lower sleeve ring 2. The inner sides of the upper sleeve ring 1 and the lower sleeve ring 2 are both connected to a clamping ring 7 through a buffer structure 6. A shock absorption assembly 8 is connected inside the clamping ring 7, and a protective pad 9 is installed inside the shock absorption assembly 8.

[0032] In the technical solution of the present invention, the upper sleeve ring 1 and the lower sleeve ring 2 are detachably connected through the locking member 3, ensuring that the assembly can be firmly fixed in the pipeline system, thereby effectively reducing the instability caused by pipeline vibration. This design avoids the displacement of the assembly during vibration, provides stronger seismic protection, and the hoisting structure 4 connected to the upper sleeve ring 1 makes the installation and disassembly more convenient, reducing the complexity of installation. The fixing structure 5 of the lower sleeve ring 2 can ensure the stability of the assembly on the ground or other supports, thereby further improving the overall seismic performance. The connection between the inner side and the clamping ring 7 through the buffer structure 6 can effectively absorb the energy of the pipeline during vibration. The buffer structure 6 is designed with elastic materials or shock absorption elements to reduce the transmission of vibration and protect the pipeline and other additional facilities from damage. The shock absorption assembly 8 connected inside the clamping ring 7 further enhances the seismic effect. The shock absorption assembly 8 is designed with a special protective pad 9, which can effectively prevent excessive impact force from directly transmitting to the pipeline system and protect the pipeline from mechanical damage. The design of the protective pad 9 can effectively buffer the impact caused by vibration, extend the service life of the pipeline and its ancillary equipment, has strong adaptability, and can be adjusted according to different requirements. Whether in a high-vibration area or a low-vibration environment, it can provide effective pipeline seismic protection and ensure the long-term stable operation of the pipeline system.

[0033] Among them, the material selection of the protective pad can be customized according to actual needs to adapt to different intensities of vibration environments. The detachable design of the locking member 3 enables the assembly to be conveniently installed and disassembled. When there are problems with the pipeline or maintenance is required, the assembly can be quickly removed for inspection and repair, reducing the complexity and time cost of maintenance.

[0034] Such asFigure 1 and Figure 2 As shown, the locking member 3 includes a locking screw 31 and a locking nut sleeve 32, the locking screw 31 is rotatably connected to the lower collar 2 through a connecting shaft 33, and a locking hole 34 is provided on the upper collar 1, and the locking screw 31 passes through the locking hole 34 and is connected to the locking nut sleeve 32; the locking screw 31 and the locking nut sleeve 32 are installed on the upper collar 1 and the lower collar 2, and are rotatably connected to the lower collar 2 through the connecting shaft 33, and the locking screw 31 is connected to the locking nut sleeve 32 through the locking hole 34 on the upper collar 1, which can ensure a firm connection between the upper and lower collars and facilitate disassembly.

[0035] like Figure 3 and Figure 4 As shown, the lifting structure 4 includes an upper mounting plate 41, which is detachably connected to the upper collar 1 by a first mounting bolt 42, and is connected to a lifting rod 43 at the top, and a lifting plate 44 is connected to the upper end of the lifting rod 43. The fixed structure 5 includes a lower mounting plate 51, which is detachably connected to the lower collar 2 by a second mounting bolt 52, and is connected to a fixing rod 53 at the bottom, and a fixing plate 54 is connected to the upper end of the fixing rod 53.

[0036] Specifically, the hoisting structure 4 and the fixed structure 5 are detachably connected to the upper collar 1 and the lower collar 2 by means of the first mounting bolt 42 and the second mounting bolt 52, making the entire system easy to assemble and disassemble. This is very convenient for installing, maintaining and transporting pipeline components, saving time and labor costs. By combining the hoisting rod 43 and the fixed rod 53 with the hoisting plate 44 and the fixed plate 54, and by combining the hoisting structure 4 and the fixed structure 5, the installation and hoisting process is more efficient, unnecessary steps are reduced, and the construction team can complete the task quickly, thereby improving the construction efficiency of the entire project. The hoisting structure 4 and the fixed structure 5 can effectively disperse vibrations and reduce the impact of external vibrations on the pipeline system. This not only improves the stability of the pipeline, but also enhances its seismic resistance, ensuring that the pipeline can maintain good performance under vibration conditions.

[0037] The hoisting rod 43 has the same structure as the fixing rod 53. The hoisting rod 43 includes two connecting rods 431 and an adjusting rod 432. The two connecting rods 431 are respectively connected to the upper collar 1 and the hoisting plate 44. Both ends of the adjusting rod 432 are detachably connected to the connecting rods 431 via adjusting bolts 433. The adjusting bolts 433 allow the adjusting rods 432 and the connecting rod 431 to be installed and removed, making it easy to replace adjusting rods 432 of different specifications. This ensures that the entire assembly is stably supported during the hoisting and fixing process, preventing loosening or falling off, ensuring the safety of the structure and flexibly responding to different environments and pipeline installation requirements.

[0038] like Figure 1 and Figure 5As shown, the buffer structure 6 includes a bottom frame 61 and a buffer frame 62. The bottom frame 61 is connected to the inner sides of the upper collar 1 and the lower collar 2, and the buffer frame 62 is connected to the outer side of the clamping ring 7. Inside the buffer frame 62, a buffer plate 64 is connected through a buffer rod 63. Below the buffer plate 64, a shock absorber 65 is connected, and a buffer spring 66 connected to the buffer frame 62 is sleeved outside the shock absorber 65. Through the combined action of design components such as the buffer frame 62, buffer rod 63, buffer plate 64, and shock absorber 65, a multi-level shock absorption system is formed. The combination of the buffer plate 64 and the shock absorber 65, combined with the shock absorption spring 652 and shock absorption rod 653, can effectively absorb external vibrations and impact forces, protecting the internal equipment or pipeline system from damage.

[0039] As Figure 5 and Figure 6 shown, a limiting chute 611 is opened inside the bottom frame 61, a limiting slider 612 adapted to the limiting chute 611 is provided on the buffer plate 64, and a plurality of heat dissipation fins 67 are provided on the buffer plate 64. By the lifting of the limiting slider 612 in the limiting chute 611, the stability of the lifting movement of the buffer plate 64 is enhanced. The plurality of heat dissipation fins 67 provided on the buffer plate 64 help to improve the heat dissipation efficiency of the buffer structure, preventing the equipment from overheating due to long-term operation. This design is particularly suitable for equipment operating for a long time or in a high-temperature environment, ensuring the stable operation of the system.

[0040] Among them, a plurality of air flow channels 621 are opened inside the buffer frame 62. One end of the air flow channel 621 is located inside the buffer frame 62, and the other end of the air flow channel 621 is located at the bottom of the buffer frame 62. The air flow channels 621 opened inside the buffer frame 62 can effectively improve internal heat dissipation through the guidance of air flow, reducing performance degradation caused by excessive temperature. The design of the air flow channels improves air circulation, helping to maintain a stable temperature inside the structure.

[0041] As Figure 1 shown, the shock absorber 65 includes a shock absorption frame 651. The upper part of the shock absorption frame 651 is connected to the buffer plate 64. Inside the shock absorption frame 651, a shock absorption spring 652 is provided. Below the shock absorption spring 652, a shock absorption rod 653 is connected, and the lower end of the shock absorption rod 653 is connected to a buffer seat 68. The buffer seat 68 includes a bottom plate 681, a buffer airbag 682 is connected to the bottom plate 681, the buffer airbag 682 is connected to one end of the shock absorption rod 653, and an air pipe 683 is provided on the buffer airbag 682. Through the buffer airbag 682 in the shock absorber 65, combined with the air pipe 683, a stronger shock absorption effect can be further provided. Especially in an environment with strong pressure or vibration, the airbag can better disperse external impact forces, reducing damage to the equipment. At the same time, the inhalation and exhalation of the air pipe 683 can accelerate the air flow inside the bottom frame 61.

[0042] As Figure 1 and Figure 9As shown, the shock absorption assembly 8 includes a first shock absorption ring 81 and a second shock absorption ring 82. The outer side of the first shock absorption ring 81 is connected to the clamping ring 7, and the outer side of the second shock absorption ring 82 is connected to the first shock absorption ring 81. A plurality of shock absorption grooves 811 are provided inside the first shock absorption ring 81, and a shock absorption spring 812 is arranged inside each shock absorption groove 811. A plurality of shock absorption cavities 821 are arranged inside the second shock absorption ring 82. The first shock absorption ring 81 and the second shock absorption ring 82 can buffer and decompress the sleeved pipeline. The plurality of shock absorption grooves 811 and shock absorption springs 812 inside the first shock absorption ring 81 can buffer the external extrusion force and offset part of the external force. Then, the deformation of the second shock absorption ring 82 and the shock absorption cavities 821 provided inside it are used for further buffering and resisting pressure, avoiding the collision of external objects on the pipeline during use and causing the pipeline to deform. At the same time, the service life of the pipeline can be extended.

[0043] Working principle: The upper sleeve ring 1 and the lower sleeve ring 2 are detachably connected by the locking member 3, ensuring that the assembly can be firmly fixed in the pipeline system, thereby effectively reducing the instability caused by pipeline vibration. This design avoids the displacement of the assembly during vibration and provides stronger earthquake resistance protection. The hoisting structure 4 connected to the upper sleeve ring 1 makes the installation and disassembly more convenient and reduces the installation complexity. The fixing structure 5 of the lower sleeve ring 2 can ensure the stability of the assembly on the ground or other supports, thereby further improving the overall earthquake resistance performance. The connection of the inner side through the buffer structure 6 to the clamping ring 7 can effectively absorb the energy of the pipeline during vibration. The buffer structure 6 reduces the transmission of vibration through the design of elastic materials or shock absorption elements, protecting the pipeline and other additional facilities from damage. The shock absorption assembly 8 connected to the inner side of the clamping ring 7 further improves the earthquake resistance effect. The shock absorption assembly 8 is designed with a special protective pad 9, which can effectively prevent excessive impact force from directly transmitting to the pipeline system and protect the pipeline from mechanical damage. The design of the protective pad 9 can effectively buffer the impact caused by vibration, extend the service life of the pipeline and its attached equipment, and has strong adaptability, which can be adjusted according to different needs. Whether in a high-vibration area or a low-vibration environment, it can provide effective pipeline earthquake resistance protection and ensure the long-term stable operation of the pipeline system.
