Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a pipeline support device suitable for water conservancy projects. Background Technology

[0002] Water conservancy pipelines are closed channel systems used in water conservancy projects to transport, distribute, and regulate water flow. During the construction and laying of pipeline networks, it is often necessary to use supporting devices to erect them. On the one hand, erecting them allows them to adapt to geological conditions such as topography, strata, and lithology. For example: 1. If the bearing capacity of soft soil layers is insufficient, burying them underground may cause the pipeline to settle and deform; 2. If the groundwater level is high, long-term immersion of the pipeline may lead to corrosion or buoyancy damage. On the other hand, based on the need for ecological protection, erecting pipelines can effectively reduce the damage to vegetation or animal habitats caused by ground excavation.

[0003] Currently, the support devices for water conservancy pipelines typically consist of two opposing semi-circular metal fixing rings fitted onto the outer surface of the pipeline, with a support base positioned below the fixing rings to support the pipeline. However, in actual use, factors such as water hammer (sudden opening and closing of valves / pumps causing pressure waves due to water flow inertia), two-phase flow instability (air trapped in the water flow, with bubbles collapsing and generating high-frequency shock waves, or solid particles such as sand and gravel trapped in the water flow, causing random vibrations when these particles impact the pipe wall), and turbulence cause pipeline vibrations. Furthermore, in existing technologies, the lack of buffering between the pipeline and the support device leads to two problems: firstly, the high-frequency alternating loads generated by vibration cause accumulated micro-damage to the pipeline, resulting in deformation and failure; secondly, continuous vibration with a large amplitude causes loosening between the pipeline and the support device, and in severe cases, the support device becomes unstable, leaving the pipeline suspended. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pipeline support device suitable for water conservancy projects, so as to solve the technical problem of lack of buffer between pipeline and support device in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pipe support device suitable for water conservancy projects includes a pipe clamp fitting fitted around the outside of the pipe; the pipe clamp fitting includes a locking ring and a limiting ring located around the locking ring, and an annular buffer space is formed between the locking ring and the limiting ring. Four radial buffer components are evenly distributed along the circumferential direction in the buffer space, including a pair in the vertical direction and a pair in the horizontal direction. The locking ring and the limiting ring are connected by the radial buffer components. The radial buffer components include an inner fixing plate and an outer fixing plate arranged opposite each other. Arch plates are provided on both sides of the inner fixing plate and the outer fixing plate, and the arch backs of the two arch plates are opposite each other. A first elastic element is provided between the two arch plates. A vertical constant resistance support component is also provided below the pipe clamp fitting. The constant resistance support component is located inside the radial buffer component and is distributed between adjacent first elastic elements.

[0007] Furthermore, the constant resistance support assembly includes a downward pressure rod and a bearing rod arranged opposite to each other. The top end of the downward pressure rod is fixedly connected to the inner fixed plate, and the bottom end of the bearing rod is fixedly connected to the outer fixed plate. The free end of the downward pressure rod gradually contracts from top to bottom to form an inverted frustum-shaped conical end. A vertical receiving groove is opened on the end face of the free end of the bearing rod. The inner diameter of the receiving groove is the same as the diameter of the bottom surface of the conical end. The top opening of the receiving groove expands outward to form a conical connecting port. The inclination of the connecting port matches that of the conical end. A second elastic element is also provided in the receiving groove to provide elastic support for the downward pressure rod.

[0008] Furthermore, multiple long strip-shaped rubber pads are evenly distributed along the circumferential direction on the inner side of the locking ring. The pipe passes through the locking ring, and the rubber pads achieve flexible contact between the pipe and the pipe.

[0009] Furthermore, both the inner fixing plate and the outer fixing plate are arc-shaped, wherein the inner fixing plate is fixedly connected to the outer side of the locking ring, and the outer fixing plate is fixedly connected to the inner side of the limiting ring;

[0010] Furthermore, a base is provided below the pipe clamp, and the pipe clamp and the base are connected and fixed by a support rod. The pipe clamp and the support rods on both sides are rotatably connected.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) Compared with the prior art, the vibration of the pipeline is buffered by the deformation of the radial buffer component, which reduces the amplitude of the pipeline while allowing the pipeline to vibrate and displace, and prevents the pipeline from deforming or even being damaged due to large amplitude during vibration.

[0013] (2) When the pipeline is tilted, the pipe clamp is rotated to match the degree of tilt of the pipeline, so that the tilted pipeline can also be adequately supported, thereby significantly improving the applicability of the entire pipeline support device. Attached Figure Description

Detailed Implementation

[0027] Example 1, specifically as follows Figures 1-10 As shown.

[0028] A pipe support device suitable for water conservancy projects includes a pipe clamp 3 sleeved around the pipe, a base 1 below the pipe clamp 3, and the pipe clamp 3 and the base 1 are connected and fixed by a support rod 2.

[0029] like Figure 1 As shown, the pipe clamp 3 includes a locking ring 301 and a limiting ring 302 located around the locking ring 301. An annular buffer space is formed between the locking ring 301 and the limiting ring 302. A radial buffer assembly 304 is provided within the buffer space, and the locking ring 301 and the limiting ring 302 are connected through the radial buffer assembly 304. It is worth noting that, in this text, "radial" refers to the radial direction of the locking ring 301, and "axial" refers to the axial direction of the locking ring 301.

[0030] The pipe clamp 3 is rotatably connected to the two side support rods 2. Specifically, horizontal connecting rods 303 are welded to both sides of the limiting ring 302. The support rod 2 is "L" shaped, and a connecting groove 202 is opened on the end face of its horizontal section. The inner diameter of the connecting groove 202 is the same as the diameter of the connecting rod 303. The connecting rod 303 is inserted into the connecting groove 202. A vertical threaded hole is opened above the connecting groove 202. The screw passes through the threaded hole and presses the connecting rod 303, thereby restricting the rotation of the connecting rod 303.

[0031] When in use, especially when the pipe is tilted, the pipe clamp 3 can be rotated to match the degree of tilt of the pipe, ensuring that the tilted pipe can also receive sufficient support, thereby significantly improving the applicability of the entire pipe support device.

[0032] In addition, it should be further explained that there is a gap between the free end of the connecting rod 303 and the bottom of the connecting groove 202. During the installation process, if there is a deviation between the pipe clamp 3 and the pipeline in the axial direction of the connecting rod 303, the pipe clamp 3 can be adjusted along the axial direction of the connecting rod 303 to calibrate the above deviation.

[0033] A rectangular mounting groove 101 is provided on the base 1, and a mounting plate 201 that matches the mounting groove 101 is welded to the bottom end of the vertical section of the support rod 2. The mounting plate 201 is fixed to the base 1 by screws.

[0034] like Figure 2As shown, the locking ring 301 includes two opposing semicircular rings. Connecting protrusions are provided at both ends of the semicircular rings, and these protrusions are integrally formed with the semicircular rings. The two opposing connecting protrusions are bolted together to form a complete locking ring 301. The length of the locking ring 301 is the same as the length of the limiting ring 302. Multiple elongated rubber gaskets 316 are evenly distributed along the circumferential direction on the inner surface of the locking ring 301. The pipe passes through the locking ring 301, and flexible contact between the pipe and the gaskets 316 is achieved.

[0035] Radial buffer components 304 are evenly distributed in the buffer space along the circumferential direction. In this embodiment, a total of four radial buffer components 304 are provided, including a pair in the vertical direction and a pair in the horizontal direction. The radial buffer components 304 include an inner fixing plate 305 and an outer fixing plate 306 arranged opposite to each other. Both the inner fixing plate 305 and the outer fixing plate 306 are arc-shaped. The inner fixing plate 305 is welded and fixed to the outer side of the locking ring 301, and the outer fixing plate 306 is welded and fixed to the inner side of the limiting ring 302. Arched plates 307 are welded to both sides of the inner fixing plate 305 and the outer fixing plate 306. The arched backs of the two arched plates 307 face each other. The arched plates 307 extend axially and the length of the arched plates 307 is the same as the length of the locking ring 301.

[0036] A first elastic element 308 is provided between the two arch plates 307. The first elastic element 308 is located at the top of the arch and is spaced apart along the axial direction. In this embodiment, the first elastic element 308 is a spring, and the two ends of the spring are welded and fixed to the two arch plates 307 respectively.

[0037] During use, the pipeline vibrates under the influence of water flow or external forces. The resulting dynamic load acts on the radial buffer assembly 304. For example, when the pipeline vibrates vertically and moves downward, the radial buffer assembly 304 directly below the pipe clamp 3 is compressed. Specifically, the arch plates 307 on both sides of the assembly bend and deform relative to each other, and the first elastic element 308 is compressed and deformed. The radial buffer assembly 304 directly above the pipe clamp 3 is stretched. Specifically, the radius of curvature of the arch plates 307 on both sides increases, the degree of bending decreases, and the overall shape tends to straighten. The first elastic element 308 is stretched and deformed. The deformation of the radial buffer assembly 304 buffers the vibration of the pipeline, allowing the pipeline to vibrate and displace while reducing its amplitude, preventing deformation or even damage to the pipeline due to large amplitude during vibration. Furthermore, reducing the amplitude also prevents loosening between the pipeline and the support device.

[0038] Considering that in actual use, the radial buffer assembly 304 located directly below the pipe clamp 3 needs to bear the weight of the water flow. When the water flow is large, especially when vibration occurs, the radial buffer assembly 304 will undergo plastic deformation under the load. The subsequent deformation cannot be recovered, resulting in the failure of the radial buffer assembly 304 and affecting the buffering effect of the entire pipeline support device.

[0039] Therefore, a vertical constant resistance support assembly 309 is also provided below the pipe clamp 3. For example... Figures 7-9 As shown, the constant resistance support assembly 309 is located inside the radial buffer assembly 304 and distributed between adjacent first elastic elements 308. The constant resistance support assembly 309 includes a downward pressure rod 310 and a support rod 311 arranged opposite to each other. The top end of the downward pressure rod 310 is welded and fixed to the inner fixing plate 305, and the bottom end of the support rod 311 is welded and fixed to the outer fixing plate 306. The free end of the downward pressure rod 310 gradually tapers from top to bottom to form an inverted frustum-shaped conical end 312. A vertical receiving groove 313 is opened on the end face of the free end of the support rod 311. The inner diameter of the receiving groove 313 is the same as the diameter of the bottom surface of the conical end 312. The top opening of the receiving groove 313 expands outward to form a conical connecting port 314. The inclination of the connecting port 314 matches that of the conical end 312. The receiving groove 313 is also provided with a second elastic element 315, which provides elastic support for the lower pressure rod 310. In this embodiment, the second elastic element 315 is a spring. One end of the spring is welded and fixed to the bottom surface of the conical end 312, and the other end of the spring is welded and fixed to the bottom of the receiving groove 313.

[0040] By setting the constant resistance support component 309, when the water flow is small, the second elastic element 315 and the radial buffer component 304 can balance the gravity of the pipe and the water flow. When the water flow is large, especially when vibration occurs, when the deformation of the second elastic element 315 and the radial buffer component 304 reaches a certain level, the pressure rod 310 contacts the pressure rod 311, and the conical end 312 enters the receiving groove 313 through the connection port 314, causing the upper end of the pressure rod 311 to undergo radial expansion deformation. The deformation of the pressure rod 311 absorbs energy, reduces the amplitude, and prevents the second elastic element 315 and the radial buffer component 304 from undergoing plastic deformation, ensuring the normal rebound and reuse of the radial buffer component 304 and the second elastic element 315.

[0041] like Figure 10As shown, an anchor rod 4 is inserted at the apex of the rectangular base 1. The anchor rod 4 includes a lower anchoring section and an upper smooth section. A helical blade is welded to the anchoring section, and a limiting plate 401 is fitted onto the smooth section. The limiting plate 401 and the smooth section of the anchor rod 4 are detachably connected by a horizontal screw. Specifically, the screw enters from the side of the limiting plate 401 and extends radially into the anchor rod 4. A insertion hole is provided at the top of the anchor rod 4 for inserting a crossbar, thereby increasing the torque when rotating the anchor rod 4.
