Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, specifically to a pipe vibration reduction device. Background Technology

[0002] Pipe clamps are structural components used to fix pipes or ground pipe fittings. They are widely used in the fixing of oil, water, and gas media pipelines in mechanical hydraulic systems of metallurgy, petroleum, chemical, vehicle, and shipbuilding industries. During installation, the direction must be determined and the pipes must be fixed by welding or screws.

[0003] In existing technologies, whether it is welding or fixing with bolts or screws, the pipe clamps are rigidly connected to the pipe. When the pipe is transporting media, especially when the media is transported in a pulsed manner, the high-frequency vibration of the pipe will inevitably cause the pipe clamps to loosen and fall off, ultimately resulting in unstable pipe fixation.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0027] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1 As shown, this utility model discloses a pipeline vibration reduction device, including a concrete pipe pier 1, a pipe pier embedded steel plate 2 embedded on the concrete pipe pier 1, and a reinforcing plate 3 serving as a pipeline support on the pipe pier embedded steel plate 2. The reinforcing plate 3 is an H-beam.

[0030] The top of the reinforcing plate 3 is equipped with a buffer pad 4, and the pipe is laid on the buffer pad 4.

[0031] An elastic anchoring component is provided on each of the reinforcing plates 3 on both sides of the pipeline. A pipe clamp 8 is provided above the reinforcing plate 3. The pipe clamp 8 includes an arc-shaped section 81 and two connecting sections 82. The arc-shaped section 81 is an arc shape that fits the outer wall of the pipeline. The two connecting sections 82 are respectively located at both ends of the arc-shaped section 81. The two connecting sections 82 are respectively connected to the two elastic anchoring components. The pipe clamp 8 can move elastically on the elastic anchoring components to absorb and disperse vibration energy and eliminate high-frequency vibration.

[0032] The elastic anchoring assembly includes bolts 5 on the stiffening plate 3, which are arranged perpendicular to the pipe axis. The stiffening plate 3 and the buffer pad 4 are respectively provided with through holes for the bolts 5 to pass through.

[0033] The bottom thread of bolt 5 has two nuts 9 that cannot pass through the through hole. The two nuts 9 are located below the through hole of the reinforcing plate 3. A flat washer 10 that contacts the reinforcing plate 3 is also fitted on bolt 5 above the two nuts 9. The nuts 9 adopt a slanted thread anti-loosening design to prevent the nuts 9 from moving on bolt 5.

[0034] The bolt 5 has a head at its top, and an elastic element 7 is provided on the lower part of the bolt 5. The head at the top of the bolt 5 forms an upper limit for the elastic element 7.

[0035] The elastic element 7 consists of multiple disc springs sleeved on the bolt 5. The disc springs are combined in pairs, and the number of disc spring combinations is at least three pairs. The disc springs can be combined in the following ways: overlapping, pairing, or compounding.

[0036] A sleeve 6 is slidably fitted onto the bolt 5 between the elastic element 7 and the stiffening plate 3. The sleeve 6 can slide along the axial direction of the bolt 5. The top end of the sleeve 6 contacts the elastic element 7, and the bottom end of the sleeve 6 is connected to the connecting section 82 of the pipe clamp 8. The connecting section 82 is bent into an L-shape, and a through hole for the bolt 5 to pass through is provided at the bottom bend of the connecting section 82. The bend of the connecting section 82 is connected to the bottom end of the sleeve 6. A gap of 15-20mm is reserved between the bottom bend of the connecting section 82 and the stiffening plate 3 to provide space for the elastic sliding of the sleeve 6 on the bolt 5.

[0037] The pipe is fixed to the stiffening plate 3 by the pipe clamp 8. The bottom of the pipe contacts the buffer pad 4 on the stiffening plate 3. The buffer pad 4 reduces vibration transmission, protects the pipe from vibration, and avoids wear on the pipe clamp 8. When the high-frequency vibration of the pipe is transmitted to the pipe clamp 8, the sleeve 6 connected to the pipe clamp 8 slides elastically on the bolt 5 to absorb and disperse the vibration energy. During the elastic sliding of the sleeve 6, the disc spring elastically expands and contracts accordingly.

[0038] This invention combines a buffer pad 4, a pipe clamp 8, a disc spring, and a sliding sleeve 6 to absorb, isolate, and dissipate the vibration energy of the pipeline, suppress high-frequency vibration of the pipeline, reduce the impact of pipeline vibration on pipeline accessories, systems, and the environment, and prevent safety accidents caused by the loosening of pipeline accessories due to pipeline vibration during production.

[0039] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
