Abstract
Description
Technical Field
[0001] This utility model relates to the field of grooved steel clamp technology, and in particular to a vibration-resistant grooved steel clamp. Background Technology
[0002] Grooved pipe clamps are fittings used to connect pipes and are widely used in fire protection, HVAC, water supply and drainage, and other fields. They use components such as clamps, sealing rings, and bolts to tightly connect two pipe sections together, providing reliable sealing and fixation. Grooved pipe clamps have advantages such as easy installation, good sealing performance, and reusability.
[0003] When existing grooved steel clamps are used in high-frequency vibration scenarios such as steam pipelines, the vibration of the pipeline will act on the grooved steel clamp, causing the grooved steel clamp to vibrate as well. This vibration will cause the connection between the grooved steel clamp and the pipeline to shift, which will lead to leakage at the pipeline connection and affect the safety and reliability of the entire pipeline system. Utility Model Content
[0004] The purpose of this invention is to provide a vibration-resistant grooved clamp to address the problem of misalignment at the connection between the grooved clamp and the pipe caused by vibration.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A vibration-resistant grooved clamp includes a pipe, on which a buffer mechanism capable of reducing the vibration amplitude of the grooved clamp is mounted;
[0007] The buffer mechanism includes an upper retaining ring and a lower retaining ring placed on the pipe. The upper and lower retaining rings are fitted with sealing rings inside. The upper retaining ring is equipped with a vibration damping component to improve the vibration resistance of the upper and lower retaining rings. The mechanism also includes a connecting component assembled on the upper and lower retaining rings.
[0008] As a further description of the above technical solution:
[0009] The vibration damping assembly includes extension rods symmetrically arranged on the lower retaining ring. A first spring is fixedly installed at the bottom end of the extension rod, and a mounting base is fixedly installed between the two first springs. A through groove is opened at the top end of the mounting base, and a crossbar is fixedly installed inside the through groove. Moving blocks are slidably connected to both sides of the surface of the crossbar, and a rotating plate is rotatably connected between the moving blocks and the extension rod. A second spring is sleeved on the surface of the crossbar.
[0010] As a further description of the above technical solution:
[0011] The mounting base has mounting holes at both ends, and the second spring is located between the two moving blocks.
[0012] As a further description of the above technical solution:
[0013] The connecting assembly includes upper clamping plates fixedly installed on both sides of the upper clamping ring, with arc-shaped blocks fixedly installed on the inner surface of the upper clamping plates, and lower clamping plates fixedly installed on both sides of the lower clamping ring. An arc-shaped groove is provided at the top of the lower clamping plate, and a limit plate is installed at the top of the lower clamping plate by screws. A support seat is fixedly installed on the limit plate.
[0014] As a further description of the above technical solution:
[0015] The extension rod is fixedly installed on the lower plate, and the support base is T-shaped, with a groove at the top of the support base having the same curvature as the bottom arc surface of the arc block.
[0016] As a further description of the above technical solution:
[0017] A first rubber pad is fixedly installed in the groove at the top of the support base, and a second rubber pad is fixedly installed at the bottom of the support base, with the bottom of the second rubber pad contacting the arc-shaped groove.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0019] 1. By incorporating vibration damping components, when the pipeline vibrates, the lower retaining ring will sway along with the pipeline. The vibration experienced by the lower retaining ring will be transmitted to the first spring through the extension rod, causing the first spring to be compressed. As the extension rod descends, it will also cause one end of the rotating plate to descend. At this time, the other end of the rotating plate will push the moving block and squeeze the second spring. During the compression and rebound process, the first and second springs will generate internal friction and damping effects, converting some of the vibration energy into heat energy, thereby reducing the vibration amplitude.
[0020] 2. By setting up connecting components and installing the upper and lower retaining rings, when the upper and lower retaining rings are affected by vibration, they will move relative to each other. At this time, the support base moves with the lower retaining ring, while the arc-shaped block moves with the upper retaining ring. Through the first rubber pad set on the top of the support base, the arc-shaped block will rub against the first rubber pad when it moves. Under extreme conditions, if the screws fixing the limiting plate loosen during vibration, the bottom end of the support base will also start to move in the arc-shaped groove through the second rubber pad. The friction between the first and second rubber pads will consume some seismic energy and reduce the vibration transmitted to the upper structure. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figure 1 - Figure 4 As shown, the present invention provides a vibration-resistant grooved steel clamp, including a pipe 10, on which a buffer mechanism 20 capable of reducing the vibration amplitude of the grooved steel clamp is mounted.
[0030] The buffer mechanism 20 includes an upper retaining ring 21 and a lower retaining ring 22 placed on the pipe 10. A sealing ring 23 is engaged inside the upper retaining ring 21 and the lower retaining ring 22. By fitting the sealing ring 23 onto the connection of the two pipes 10, and then installing the upper retaining ring 21 and the lower retaining ring 22, the sealing ring 23 is located inside the upper retaining ring 21 and the lower retaining ring 22, thereby completing the sealing of the connection of the two pipes 10. The upper retaining ring 21 is equipped with a vibration damping component 24 to improve the vibration resistance of the upper retaining ring 21 and the lower retaining ring 22. The vibration damping component 24 can dampen the vibration of the pipe 10. It also includes a connecting component 25 assembled on the upper retaining ring 21 and the lower retaining ring 22. The connecting component 25 can reduce the vibration of the upper retaining ring 21 and the lower retaining ring 22 while installing them.
[0031] like Figure 1 - Figure 2 As shown, the vibration damping assembly 24 includes an extension rod 241 symmetrically arranged on the lower retaining ring 22. A first spring 242 is fixedly installed at the bottom end of the extension rod 241. Both the first spring 242 and the second spring 248 are damping springs. A mounting base 243 is fixedly installed between the two first springs 242. When the lower retaining ring 22 is subjected to vibration from the pipe 10, the lower retaining ring 22 will shake with the pipe 10. At this time, the vibration of the lower retaining ring 22 will be transmitted to the first spring 242 through the extension rod 241. The extension rod 241 will be compressed and descend, which will squeeze the first spring 242, thus compressing the first spring 242.
[0032] The top of the mounting base 243 has a through groove 244, and a crossbar 245 is fixedly installed inside the through groove 244. Moving blocks 246 are slidably connected to both sides of the surface of the crossbar 245. A rotating plate 247 is rotatably connected between the moving blocks 246 and the extension rod 241. A second spring 248 is sleeved on the surface of the crossbar 245. When the extension rod 241 descends, it also drives one end of the rotating plate 247 to descend. At this time, the other end of the rotating plate 247 will push the moving blocks 246, so that the moving blocks 246 on both sides move towards the opposite surface and squeeze the second spring 248 while moving. During the compression and rebound process, the first spring 242 and the second spring 248 will generate internal friction and damping effect, converting some of the vibration energy into heat energy, thereby reducing the vibration amplitude.
[0033] In more detail, mounting holes are provided at both ends of the mounting base 243, which allows the mounting base 243 to be installed on a wall or other place. The second spring 248 is located between the two moving blocks 246.
[0034] like Figure 3 - Figure 4As shown, the connecting assembly 25 includes upper retaining plates 251 fixedly installed on both sides of the upper retaining ring 21. An arc-shaped block 252 is fixedly installed on the inner surface of the upper retaining plate 251. Lower retaining plates 253 are fixedly installed on both sides of the lower retaining ring 22. An arc-shaped groove 254 is formed at the top of the lower retaining plate 253. A limiting plate 255 is installed at the top of the lower retaining plate 253 by screws. A support seat 256 is fixedly installed on the limiting plate 255. After the upper retaining ring 21 and the lower retaining ring 22 are installed, the support seat 256 is placed on the upper retaining plate 251 and the lower retaining plate 253. Between them, the limiting plate 255 and the lower clamping plate 253 are fixed together by screws. When the pipe 10 vibrates, the upper clamping ring 21 and the lower clamping ring 22 will be affected by the vibration and generate relative movement. At this time, the support seat 256 moves with the lower clamping ring 22, while the arc-shaped block 252 moves with the upper clamping ring 21. Through the first rubber pad set on the top of the support seat 256, the arc-shaped block 252 will rub against the first rubber pad when it moves. The friction will consume some seismic energy and reduce the vibration transmitted to the upper structure.
[0035] Under extreme conditions, if the screws of the fixed limiting plate 255 become loose during this vibration, the bottom end of the support 256 will also begin to move within the arc groove 254, consuming some of the seismic energy through the second rubber pad and reducing the vibration transmitted to the upper structure.
[0036] In more detail, the extension rod 241 is fixedly installed on the lower clamping plate 253, and the support seat 256 is T-shaped. When the upper clamping plate 251 moves, the T-shaped setting of the support seat 256 can play a limiting role. The top of the support seat 256 is provided with a groove with the same curvature as the bottom arc surface of the arc block 252.
[0037] In more detail, a first rubber pad is fixedly installed in the groove at the top of the support 256, and a second rubber pad is fixedly installed at the bottom of the support 256, with the bottom of the second rubber pad contacting the arc-shaped groove 254.
[0038] Working principle: In use, the sealing ring 23 is fitted onto the connection of the two pipes 10, and then the upper retaining ring 21 and the lower retaining ring 22 are installed so that the sealing ring 23 is located inside the upper retaining ring 21 and the lower retaining ring 22. The upper retaining ring 21 and the lower retaining ring 22 are installed together by the mounting support 256. Then the mounting base 243 is installed on the wall or other places through the mounting hole.
[0039] When the pipe 10 vibrates, the lower retaining ring 22 will sway with the pipe 10. The vibration of the lower retaining ring 22 will be transmitted to the first spring 242 through the extension rod 241. The extension rod 241 will be compressed and descend, squeezing the first spring 242. As the extension rod 241 descends, it will also drive one end of the rotating plate 247 to descend. At this time, the other end of the rotating plate 247 will push the moving block 246, causing the moving blocks 246 on both sides to move towards the opposite side and squeeze the second spring 248 while moving. During the compression and rebound process, the first spring 242 and the second spring 248 will generate internal friction and damping effect, converting some of the vibration energy into heat energy, thereby reducing the vibration amplitude.
[0040] At the same time, the upper retaining ring 21 and the lower retaining ring 22 will be affected by vibration and will move relative to each other. At this time, the support base 256 moves with the lower retaining ring 22, while the arc block 252 moves with the upper retaining ring 21. Through the first rubber pad set on the top of the support base 256, the arc block 252 will rub against the first rubber pad when it moves. The friction will consume some of the seismic energy and reduce the vibration transmitted to the upper structure.
[0041] Under extreme conditions, if the screws of the fixed limiting plate 255 become loose during this vibration, the bottom end of the support 256 will also begin to move within the arc groove 254, consuming some of the seismic energy through the second rubber pad and reducing the vibration transmitted to the upper structure.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
