Description

Technical Field

[0001] This utility model relates to the field of pipe supports, and in particular to a frame that reduces swaying. Background Technology

[0002] During operation, pipelines experience thermal expansion and contraction due to changes in the temperature of the medium (such as hot water or steam) or the ambient temperature. If the pipeline is rigidly fixed, this expansion and contraction can generate enormous stress, potentially leading to pipeline rupture, joint leaks, or equipment damage. Sliding supports, as a key component ensuring the safe operation of pipelines, function by providing stable support while allowing axial displacement due to temperature changes and other factors. This releases internal thermal stress within the pipeline system and prevents damage from excessive stretching or compression. These supports are widely used in various industrial and civil pipeline systems, including petroleum, chemical, and water supply and drainage systems, and are a crucial foundation for maintaining the long-term stable operation of these systems.

[0003] While traditional sliding supports provide basic support and axial sliding, they are significantly inadequate in resisting swaying. Due to their weak lateral (perpendicular to the axial) constraint in their structural design, pipes mounted on sliding supports are prone to lateral swaying when subjected to fluid impact, external vibration, or other lateral forces. This swaying not only affects the stability of the pipeline system but can also lead to loosening of pipe connections, seal failure, and even fatigue damage over time, posing safety hazards. This deficiency is particularly pronounced in industrial settings where high pipeline stability is required, necessitating improvement. Utility Model Content

[0004] The main purpose of this utility model is to provide a frame that reduces swaying, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A frame for reducing sway includes a fixed base, on which a sliding fixing structure is slidably mounted, and an adjusting structure is rotatably mounted on the fixed base. A lateral limiting structure is mounted on the adjusting structure. The lateral limiting structure consists of a connecting plate, a U-shaped connecting frame, a U-shaped support frame, a fixed shaft, and support rollers. Two U-shaped connecting frames are symmetrically fixedly mounted on the outer ends of the connecting plate. Two U-shaped support frames are respectively fixedly mounted on one end of each of the two U-shaped connecting frames. Two fixed shafts are respectively fixedly mounted inside the two U-shaped support frames. Two support rollers are rotatably mounted on the two fixed shafts.

[0007] Preferably, the fixed base consists of a base body and a T-shaped guide rail, the T-shaped guide rail is fixedly installed on the upper end of the base body, and the base body is provided with mounting holes.

[0008] Preferably, the sliding fixing structure consists of a pipe clamp and a connecting block. The pipe clamp is fixedly installed on the upper end of the connecting block, and a T-shaped groove is provided on the lower end of the connecting block. The connecting block is slidably installed on the T-shaped guide rail through the T-shaped groove.

[0009] Preferably, the adjustment structure is rotatably installed in a mounting hole opened on the base body.

[0010] Preferably, the adjustment structure consists of a base rod, screws, and handles. The base rod is located inside the mounting hole. There are two screws that are symmetrically fixed at both ends of the base rod and are located on the outside of the base body. There are two handles that are fixedly fixed at one end of each of the two screws.

[0011] Preferably, the connecting plate on the lateral limiting structure contacts the base body, the connecting plate has a screw hole, the connecting plate is installed on the screw rod through the screw hole, the U-shaped support frame is located above the connecting plate, and the four support rollers on the two lateral limiting structures are respectively located on both sides of the pipe clamp.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting an adjustment structure on a fixed base, and then incorporating a lateral limiting structure consisting of a connecting plate, a U-shaped connecting frame, a U-shaped support frame, a fixed shaft, and support rollers, the adjustment structure, in conjunction with the lateral limiting structure, can laterally limit the pipe fixed within the sliding fixed structure. This effectively reduces the pipe's swaying in the lateral direction, preventing problems such as loosening of connections, seal failure, or fatigue damage caused by swaying. Simultaneously, the support rollers in the lateral limiting structure can rotate with the axial displacement of the pipe, providing a limiting function without hindering the normal axial sliding of the pipe due to thermal expansion and contraction, ensuring stable constraint while allowing the pipe to expand and contract freely. Furthermore, rotating the adjustment structure allows for easy adjustment of the spacing of the lateral limiting structure according to pipes of different diameters, improving the applicability and flexibility of the lateral limiting structure and better meeting the stability requirements of pipes in different scenarios.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a frame for reducing sway includes a fixed base 1, a sliding fixing structure 2 slidably mounted on the fixed base 1, an adjusting structure 3 rotatably mounted on the fixed base 1, and a lateral limiting structure 4 mounted on the adjusting structure 3. The lateral limiting structure 4 consists of a connecting plate 13, a U-shaped connecting frame 15, a U-shaped support frame 16, a fixed shaft 17, and support rollers 18. There are two U-shaped connecting frames 15 symmetrically fixedly mounted on the outer ends of the connecting plate 13. There are two U-shaped support frames 16, each fixedly mounted on one end of a U-shaped connecting frame 15. There are two fixed shafts 17, each fixedly mounted inside a U-shaped support frame 16. There are two support rollers 18, each rotatably mounted on a fixed shaft 17. By setting the adjusting structure 3 on the fixed base 1, and setting the adjusting structure 3 with the connecting plate 13, U-shaped connecting frame 15, U-shaped support frame 16, and U-shaped support rollers 17, the lateral limiting structure 4 is achieved. The lateral limiting structure 4, composed of the support frame 16, the fixed shaft 17, and the support roller 18, works in conjunction with the adjusting structure 3 to laterally limit the pipe fixed within the sliding fixed structure 2. This effectively reduces the pipe's swaying in the lateral direction, preventing problems such as loosening of connections, seal failure, or fatigue damage caused by swaying. Simultaneously, the support roller 18 in the lateral limiting structure 4 can rotate with the axial displacement of the pipe, providing a limiting function without hindering the normal axial sliding of the pipe due to thermal expansion and contraction, ensuring stable constraint while allowing the pipe to expand and contract freely. Furthermore, by rotating the adjusting structure 3, the spacing of the lateral limiting structure 4 can be easily adjusted according to pipes of different diameters, improving the applicability and flexibility of the lateral limiting structure 4 and better meeting the stability requirements of pipes in different scenarios.

[0021] Specifically, the fixed base 1 consists of a base body 5 and a T-shaped guide rail 6. The T-shaped guide rail 6 is fixedly installed on the upper end of the base body 5. The base body 5 has a mounting hole 7. The sliding fixing structure 2 consists of a pipe clamp 8 and a connecting block 9. The pipe clamp 8 is fixedly installed on the upper end of the connecting block 9. The lower end of the connecting block 9 has a T-shaped groove. The connecting block 9 is slidably installed on the T-shaped guide rail 6 through the T-shaped groove. The adjusting structure 3 is rotatably installed in the mounting hole 7 on the base body 5. The adjusting structure 3 consists of a base rod 10, a screw rod 11, and a handle 12. The base rod 10 is located in the mounting hole 7. There are two screw rods 11, which are symmetrically fixed at both ends of the base rod 10 and are located on the outside of the base body 5. There are two handles 12, which are fixedly installed at one end of each of the two screw rods 11. The connecting plate 13 on the transverse limiting structure 4 contacts the base body 5. The connecting plate 13 has a screw hole 14. The U-shaped support frame 16 is located above the connecting plate 13 and is installed on the screw rod 11 through the screw hole 14. The four support rollers 18 on the two transverse limiting structures 4 are located on both sides of the pipe clamp 8. In use, the base body 5 of the fixed base 1 is fixedly installed in the designated position through the mounting hole 7, and the pipe clamp 8 is fixedly installed on the pipe to be fixed. Then, the handle 12 of the adjusting structure 3 is rotated, thereby driving the screw rod 11 and the base rod 10 to rotate on the base body 5. This causes the connecting plate 13 on the transverse limiting structure 4 to move on the screw rod 11 through the screw hole 14 until the support rollers 18 on the fixed shaft 17 inside the U-shaped support frame 16 contact the outer wall of the pipe. When the pipe undergoes axial displacement due to thermal expansion and contraction, the pipe will drive the connecting block 9 of the sliding fixed structure 2 to slide along the T-shaped guide rail 6. At the same time, the support rollers 18 of the transverse limiting structure 4 will rotate on the fixed shaft 17 with the axial displacement of the pipe.

[0022] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
