Description

[0002] As the main load-bearing components of the pipeline transportation system, the main functions of the pipeline support and hanger are to bear the load of equipment such as pipelines or valves, limit the displacement of pipelines, control pipeline vibration, etc., to ensure the safe operation of pipelines. Considering that for various mechanical devices, dynamic load suppression issues such as vibration reduction, noise reduction, and earthquake resistance are very important, pipeline supports and hangers should also have good pipeline noise filtering capabilities and dynamic load resistance capabilities. Supports and hangers with elastic and damping characteristics and equipped with limit structures are one of the effective means to solve the above problems. On the one hand, by adjusting the stiffness and damping characteristics of the elastic support and hanger, the inherent vibration characteristics of the elastic support and hanger can be adjusted, thereby effectively reducing the transmission of the vibration of the pipeline system to external structures or components; on the other hand, by adjusting the stiffness of the elastic support and hanger and adding a limit device, the transmission of external dynamic loads to the pipeline system through the support system can be effectively resisted, thereby reducing the dynamic load transmission rate, protecting the pipeline system, and improving the protection capability of the pipeline system.

[0029] Combine the following Figure 1-Figure 6 The present invention describes a pipeline support and hanger with a dynamic load suppression function. The pipeline support and hanger with a dynamic load suppression function comprises: a pipe clamp, a connecting plate 4 , a first support seat 5 , an elastic element 6 and a second support seat 7 .

[0030] Among them, the pipe clamp is clamped on the outer wall of the pipe 3; one end of the connecting plate 4 is connected to the pipe clamp; one end of the first support seat 5 is connected to the other end of the connecting plate 4; the elastic element 6 includes an origami-type thin-walled tubular structure made of metal or polymer materials, and one end of the origami-type thin-walled tubular structure is connected to the first support seat 5; the second support seat 7 is connected to the other end of the origami-type thin-walled tubular structure.

[0031] Specifically, the pipe clamp is clamped on the outer wall of the pipe 3 and is used to be fixed to the pipe 3. The connecting plate 4 is used to connect the pipe clamp and the first supporting seat 5. A space for installing the elastic element 6 is reserved between the first supporting seat 5 and the second supporting seat 7. The elastic element 6 is used to provide elastic force for the first supporting seat 5, and the second supporting seat 7 can serve as a supporting structure of the overall structure.

[0032] One end of the connecting plate 4 is fixedly connected to the lower part of the pipe clamp, and the other end is fixedly connected to the first supporting seat 5. Generally, the first supporting seat 5 is an upper supporting seat, and the second supporting seat 7 is a lower supporting seat, and an elastic element 6 is connected in the middle.

[0033] Furthermore, one or more elastic elements 6 can be provided, and multiple elastic elements 6 can be connected in parallel between the first support seat 5 and the second support seat 7. If the stiffness coefficient of one elastic element 6 is k, the total stiffness coefficient of n elastic elements 6 is nk. The elastic element 6 has the characteristics of a periodic origami thin-walled cylindrical structure, and its stiffness coefficient can be customized, and can be designed within a larger stiffness range by adjusting the size of the origami thin-walled sensitive structure.

[0034] When the origami thin-walled sensitive structure has a slender feature, it is locally prone to compression and buckling, which reduces the stiffness, and its vibration reduction performance improves with the increase of the slenderness ratio of the thin-walled structure; when the origami thin-walled sensitive structure has a short and thick feature, the overall stiffness increases, the elastic element 6 has good anti-dynamic load performance, and can achieve buffering and energy absorption through plastic deformation.

[0035] Furthermore, the inside of the thin-walled cylinder can be filled with a buffer material with a damping effect, such as high temperature and radiation resistant silicone rubber and metal rubber; the elastic element 6 can be made of high temperature and radiation resistant metal materials, such as carbon steel, silicon manganese alloy steel, etc., or non-metallic materials with good elasticity, such as polymer materials, etc. Its processing method can be extrusion molding, 3D printing, mechanical cutting, etc. It should be understood that the material and processing technology of the elastic element 6 are selected according to actual needs, such as according to the specific working environment.

[0036] It can be seen that the present invention has the following beneficial effects: 1. The present invention has a simple structure and can realize elastic elements 6 with different stiffness coefficients k by designing the size of an origami-type thin-walled tubular structure. The total stiffness of the elastic element group can be approximately nk by combining different numbers n of elastic elements 6 in parallel.

[0037] 2. The present invention can adjust the rigidity characteristics of the support and hanger brackets to meet the corresponding vibration reduction and dynamic load resistance requirements by only replacing the elastic element 6 itself or changing the number of the elastic elements 6 without changing the external dimensions of the support and hanger brackets.

[0038] 3. The present invention has good structural stability and repeatability, and has no special requirements for processing and manufacturing accuracy and installation methods.

[0039] The present invention provides a pipeline support and hanger with a dynamic load suppression function, which includes: a pipe clamp, a connecting plate 4, a first support seat 5, an elastic element 6 and a second support seat 7. The pipe clamp is clamped on the outer wall of the pipeline 3; one end of the connecting plate 4 is connected to the pipe clamp; one end of the first support seat 5 is connected to the other end of the connecting plate 4; the elastic element 6 includes an origami-type thin-walled tubular structure made of metal or polymer materials, and one end of the origami-type thin-walled tubular structure is connected to the first support seat 5; the second support seat 7 is connected to the other end of the origami-type thin-walled tubular structure. The present invention provides a pipeline support and hanger with a dynamic load suppression function, which clamps the pipeline 3 by a pipe clamp, connects the pipe clamp and the first support seat 5 by a connecting plate 4, and connects the first support seat 5 and the second support seat 7 by an elastic element 6; and the elastic element 6 can be designed with an origami-type thin-walled tubular structure to realize elastic elements 6 with different stiffness coefficients k, and the total stiffness of the elastic element group can be obtained by combining different numbers n of elastic elements 6 in parallel. The stiffness characteristics of the support and hanger can be adjusted to meet the corresponding vibration reduction and dynamic load resistance requirements without changing the external dimensions of the support and hanger, only by replacing the elastic element 6 itself or changing the number of elastic elements 6; the transmission of the pipeline load can be achieved by deforming the origami-type thin-walled tubular structure; the pipeline support and hanger with a dynamic load suppression function of the present invention has structural stability and good repeatability, and has no special requirements for processing and manufacturing accuracy and installation methods.

[0040] In one of the embodiments of the present invention, the pipe support and hanger with dynamic load suppression function also includes: a limiting bracket 9, one end of which is connected to the second support seat 7, and the other end forms a limiting groove, and the first support seat 5 is limited in the limiting groove. In this embodiment, due to the setting of the elastic element 6, the first support seat 5 and the second support seat 7 are movably connected, and the movement range of the first support seat 5 is limited by setting the limiting bracket 9. Specifically, the limiting bracket 9 is symmetrically arranged on the left and right, one end is fixedly connected to the second support seat 7, and the limiting groove formed at the other end is located on the upper and lower sides of the first support seat 5, so as to limit the first support seat 5 along the telescopic direction of the elastic element 6. Figure 1 In the structure shown, the movement of the first support seat 5 in the up and down directions is limited.

[0041] In one embodiment of the present invention, the limiting groove includes: a first limiting plate and a second limiting plate, and the first limiting plate and the second limiting plate are arranged on both sides of the first support seat 5 along the extension direction of the elastic element 6. Specifically, the limiting groove limits the movement of the first support seat 5 in the up and down directions, so in the extension direction of the elastic element 6, the first limiting plate and the second limiting plate are respectively installed on the upper and lower sides of the first support seat 5, thereby forming the limiting groove.

[0042] Preferably, the limiting brackets 9 are symmetrically arranged, such as Figure 1In the structure shown, the limiting bracket 9 on the left side is an "F"-shaped structure, and the right side is a mirror image setting, with limiting grooves formed on both sides of the first support seat 5 to achieve a limiting effect on the first support seat 5.

[0043] In one embodiment of the present invention, the origami-type thin-walled tubular structure comprises: a plurality of groups of circular rings connected in sequence along the axial direction, each circular ring group comprises: a plurality of circular rings of different thicknesses connected in sequence along the axial direction. Figure 1 and Figure 2 In the structure shown, the structural feature of a single origami-type thin-walled tubular structure is a group of circular rings whose cross-sections change periodically along the axial direction. The stiffness coefficient of the elastic element 6 can be adjusted by adjusting the thickness and height of the internal circular rings. For different working conditions, elastic elements 6 with different stiffness coefficients can be replaced to meet the dynamic load suppression function of the pipeline 3.

[0044] The specific structure of the ring group is described in detail through the following three embodiments.

[0045] Embodiment 1: like Figure 3 As shown, the circular ring group in this embodiment includes: a first circular ring 61 with a first thickness and a second circular ring 62 with a second thickness arranged coaxially, and the first thickness is greater than the second thickness, and the second circular ring 62 is arranged farther away from the axis than the first circular ring 61.

[0046] In this embodiment, the ring group is formed by axially connecting a first ring 61 and a second ring 62 of different thicknesses, and the heights of the first ring 61 and the second ring 62 may be the same or different. The second ring 62 is arranged away from the axis compared to the first ring 61, which means that because the thickness of the second ring 62 is less than the thickness of the first ring 61, the above meaning is expressed as that the centroid of the second ring 62 is arranged away from the axis compared to the centroid of the first ring 61.

[0047] Preferably, the outer wall of the second ring 62 and the outer wall of the first ring 61 are on the same straight line, that is, the outer walls of the first ring 61 and the second ring 62 are flush, and the inner walls are staggered with protrusions and grooves, and a ring group is formed by a plurality of alternately arranged first rings 61 and second rings 62.

[0048] Embodiment 2: like Figure 4 As shown, the circular ring group in this embodiment includes: a third circular ring 63 with a third thickness and a fourth circular ring 64 with a fourth thickness arranged coaxially, and the third thickness is greater than the fourth thickness, and the fourth circular ring 64 is arranged closer to the axis than the third circular ring 63.

[0049] In this embodiment, the ring group is formed by axially connecting a third ring 63 and a fourth ring 64 of different thicknesses, and the heights of the third ring 63 and the fourth ring 64 can be the same or different. The fourth ring 64 is arranged closer to the axis than the third ring 63, which means that because the thickness of the fourth ring 64 is less than the thickness of the third ring 63, the above meaning is expressed as the centroid of the third ring 63 is arranged farther from the axis than the centroid of the fourth ring 64.

[0050] Preferably, the inner wall of the fourth ring 64 and the inner wall of the third ring 63 are on the same straight line, that is, the inner walls of the fourth ring 64 and the third ring 63 are flush, and the outer walls are staggered with protrusions and grooves, and a ring group is formed by multiple alternating fourth rings 64 and third rings 63.

[0051] Embodiment 3: like Figure 5 As shown, the ring group in this embodiment includes: a plurality of fifth rings 65 with a fifth thickness and a plurality of sixth rings 66 with a sixth thickness, which are coaxially arranged, and the fifth thickness is greater than the sixth thickness. The sixth rings 66 and the fifth rings 65 are alternately arranged along the axis direction, and the plurality of sixth rings 66 are alternately arranged away from or close to the axis compared to the fifth rings 65.

[0052] In this embodiment, the ring group is formed by axially connecting two fifth rings 65 and two sixth rings 66 of different thicknesses, and the heights of the fifth ring 65 and the sixth ring 66 can be the same or different. Moreover, the fifth ring 65 and the sixth ring 66 are alternately arranged, and the plurality of sixth rings 66 are alternately arranged away from or close to the axis compared to the fifth ring 65. This means that because the thickness of the sixth ring 66 is less than the thickness of the fifth ring 65, the above meaning is expressed as follows: the centroid of the sixth ring 66 is alternately arranged away from and close to the axis compared to the centroid of the fifth ring 65, that is, the previous sixth ring 66 is arranged close to the axis, and the next sixth ring 66 is arranged away from the axis.

[0053] Preferably, the multiple sixth rings 66 arranged along the axis are arranged in sequence so that their outer walls are on the same straight line with the outer wall of the fifth ring 65, and their inner walls are on the same axis with the inner wall of the fifth ring 65, that is, the outer wall of the previous sixth ring 66 is flush with the outer wall of the fifth ring 65, and the inner wall of the next sixth ring 66 is flush with the inner wall of the fifth ring 65, and they are arranged in this way.

[0054] It can be seen that by adjusting the thickness, height and combination of each ring in the above embodiment, a specific stiffness coefficient can be obtained; by designing the number of periods of the ring group, the stiffness coefficient k of a single elastic element 6 can be easily obtained; by arraying or arranging the number n of elastic elements 6, the stiffness coefficient nk of the elastic support (elastic element combination) can be easily obtained.

[0055] In one embodiment of the present invention, a plurality of elastic elements 6 are provided, and the plurality of elastic elements 6 are sequentially arranged along the horizontal direction of the first support seat 5 and the second support seat 7; and / or, a buffer material having a damping effect is filled inside the origami-type thin-walled tubular structure. Figure 1 In the structure shown, six elastic elements 6 are horizontally arranged between the first supporting seat 5 and the second supporting seat 7 .

[0056] In one embodiment of the present invention, the pipe clamp includes: a first pipe clamp 1 and a second pipe clamp 2 arranged opposite to each other, the first pipe clamp 1 and the second pipe clamp 2 both form a semicircular groove structure, and the first pipe clamp 1 and the second pipe clamp 2 arranged opposite to each other form a circular clamping structure to clamp on the outer wall of the pipe 3. Specifically, the pipe clamp in this embodiment consists of the first pipe clamp 1 and the second pipe clamp 2 arranged opposite to each other.

[0057] In one embodiment of the present invention, the pipe support and hanger with dynamic load suppression function further includes: a fastener 8, the first pipe clamp 1 and the second pipe clamp 2 are both formed with assembly holes, and the fastener 8 sequentially passes through the assembly holes on the first pipe clamp 1 and the second pipe clamp 2 to fasten the first pipe clamp 1 and the second pipe clamp 2. Specifically, the fastener 8 can be a bolt and a nut, the bolt is sequentially passed through the assembly holes on the first pipe clamp 1 and the second pipe clamp 2, and the nut is used to cooperate with the locking bolt, so that the first pipe clamp 1 and the second pipe clamp 2 fix the pipe 3.

[0058] The present invention provides a pipe support and hanger with dynamic load suppression function, and its specific working principle is as follows: the load of the pipe 3 is transmitted to the elastic element 6 through the first pipe clamp 1, the second pipe clamp 2, the connecting plate 4 and the first support seat 5 in sequence, and finally to the second support seat 7; the elastic element 6 is deformed by the origami-type thin-walled tubular structure, that is, the cross-section is changed from the initial step type (for example: as Figure 3 , 4 or the structure shown in 5) into a W-type (i.e. Figure 2 The structure shown in the figure) realizes the function of vibration reduction and isolation.

[0059] According to the structure of the above embodiment, the present invention provides an assembly and use method of the pipeline support and hanger with dynamic load suppression function: The pipe support and hanger with dynamic load suppression function in the present invention can be installed horizontally, or can be installed laterally by rotating 90° around the pipe axis, or installed by hanging 180°. Taking horizontal installation as an example, the specific installation method is described as follows: First, according to the vibration and noise reduction requirements of pipeline 3, the pipe system is calculated to determine the position where pipeline 3 needs to be supported, and the elastic parameters of the elastic supports and hangers are determined.

[0060] Then, the rooting position of the support bracket is determined according to the position where the pipeline 3 needs to be supported, and the second support seat 7 is installed at the rooting position; then the elastic element 6 is installed on the upper surface of the second support seat 7, and the first support seat 5 is installed on the upper surface of the elastic element 6; at this time, the first support seat 5, the second support seat 7 and the elastic element 6 form a sandwich-like structure.

[0061] Afterwards, the second pipe clamp 2 is connected to the first support seat 5 through the connecting plate 4, so that the supported pipe 3 is placed between the first pipe clamp 1 and the second pipe clamp 2, and the first pipe clamp 1 and the second pipe clamp 2 arranged up and down are firmly connected by the fastening bolts on both sides; finally, the limiting bracket 9 is installed to ensure that the first support seat 5 is in a suitable gap position.

[0062] During the normal operation of the pipe support and hanger with dynamic load suppression function, the vibration is transmitted from the supported pipe 3 through the pipe clamp to the first support seat 5, the elastic element 6 and the second support seat 7, and even to the root position of the support and hanger, that is, the base or shell of the power device. Taking a typical pipe 3 as an example, if the equivalent mass of the supported pipe is 30kg, the equivalent mass of the steel structure of the support and hanger is 10kg, the stiffness coefficient is 1.8E4N / mm, and the damping ratio is 0.01, the equivalent stiffness coefficient of a single origami-type thin-walled tubular structure is 1.5E3N / mm, and the damping ratio is 0.1, the vibration isolation effect of the entire elastic support and hanger is as follows: Figure 6 shown. Figure 6 It shows that by adjusting the number of elastic elements 6 (1-4), the total stiffness characteristics of the elastic element group can be adjusted, thereby adjusting the vibration isolation effect of the entire elastic support bracket.

[0063] When the elastic support hanger is subjected to dynamic loads such as earthquakes, the elastic element group will undergo a significant deformation due to inertia, causing the first support seat 5 to move upward or downward. When the movement displacement value reaches the gap value, the limit bracket 9 starts to work, limits the first support seat 5, and provides sufficient rigid support for the elastic support hanger to avoid structural failure of the elastic support hanger.

[0064] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, i.e., they may be located in one place, or they may be distributed over multiple units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. Those of ordinary skill in the art may understand and implement the present invention without creative effort.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
