Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, specifically a single-pipe seismic support. Background Technology

[0002] In earthquake-prone areas, people have gradually realized the importance of seismic resistance in pipeline systems and have begun to try to improve traditional pipeline fixing methods. Early seismic bracing designs were relatively simple, mainly improving pipeline stability by increasing the number and strength of fixing points, but the shock absorption effect was limited, hence the development of seismic bracing.

[0003] A search revealed a utility model patent with Chinese patent publication number CN211738223U, which discloses a single-tube seismic brace. The brace includes a support frame with rollers rotatably connected to both ends. A conveyor belt is provided on the circumference of the rollers. A rotary motor is provided on one side of the support frame, and the output shaft of the rotary motor is fixedly connected to one end of the rollers. A connecting frame is fixedly connected to the support frame, and a sorting device is fixedly connected to the connecting frame. The sorting device includes a drive motor fixedly connected to the connecting frame.

[0004] The above-mentioned device supports the pipe through a support frame and uses rubber pads for shock absorption. However, since the structure of the support frame is relatively fixed, it can only be used to support pipes of one specification, which is not adaptable enough and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a single-tube seismic brace to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-tube seismic brace, comprising a mounting base and two movable plates. Two horizontally arranged mounting plates are fixedly connected to the outer wall of one side of the mounting base. The two movable plates are equipped with a fixing component, which includes six connecting feet. The top two connecting feet are slidably connected to the inside of the top movable plate, and the bottom four connecting feet are slidably connected to the inside of the bottom movable plate. The top two connecting feet are fixedly connected to the same covering piece two, and the bottom two adjacent connecting feet are fixedly connected to the same covering piece one. An adjustment structure is installed inside each of the two mounting plates. The adjustment structure includes a support frame, a lead screw, and two limiting rods.

[0007] As a further preferred embodiment of this technical solution, the lead screw is threaded inside the mounting plate, both limiting rods are slidably inserted into the mounting plate, the support frame is rotatably connected to the end of the lead screw, and one end of each of the two limiting rods is fixedly connected to the outside of the support frame.

[0008] It can clamp and fix pipes of different specifications and ensure that the pipe is stable enough, which is beneficial to improving the adaptability of the support. The pipe is placed between two moving plates, then the second covering plate is wrapped around the outside of the pipe and inserted into the inside of the top moving plate. Then, the two first covering plates are wrapped around the outside of the pipe and fixed inside the bottom moving plate. The screw is rotated by the wheel, and the support frame moves away from the pipe under the drive of the screw and the restriction of the two limit rods. As the tension increases, the elastic second covering plate will cover half or more of the pipe. Repeat the operation, and the two first covering plates will wrap the other half or more of the pipe. With the cooperation of the two, the pipe will be firmly fixed.

[0009] As a further preferred embodiment of this technical solution, a shock-absorbing component is installed between the movable plate and the support frame. The shock-absorbing component includes two placement chambers, which are respectively fixedly connected to both sides of the bottom outer wall of the support frame. A shock-absorbing pad is slidably inserted into each of the two placement chambers. A contact block is fixedly connected to both sides of the bottom outer wall of the movable plate, and the two contact blocks are respectively attached to the top wall of the two shock-absorbing pads.

[0010] When the pipeline moves downward due to vibration, the pipeline drives the second covering plate and the moving plate to move downward. The moving plate drives the contact block to move synchronously, and the shock-absorbing pad is compressed under force. Due to its unique molecular structure and physical properties, it can convert mechanical vibration energy into heat energy or other forms of energy, thereby reducing vibration transmission. Conversely, when the pipeline moves upward due to vibration, the two shock-absorbing pads at the bottom can also achieve the anti-vibration effect, which is beneficial to improving the anti-vibration effect of the support.

[0011] As a further preferred embodiment of this technical solution, a limiting groove is provided inside both sides of the support frame, and a plug-in plate is provided on the outer wall of the side of the two contact blocks that are far apart from each other. The two plug-in plates are slidably connected inside the two limiting grooves respectively.

[0012] As a further preferred embodiment of this technical solution, the thread helix angle of the lead screw thread is smaller than the equivalent friction angle.

[0013] As a further preferred embodiment of this technical solution, several reinforcing plates are fixedly connected to the top and bottom outer walls of both mounting plates, and one end of each of the reinforcing plates is fixedly connected to the outer wall of one side of the mounting base.

[0014] As a further preferred embodiment of this technical solution, both the first and second coating sheets are made of mild steel.

[0015] This utility model provides a single-tube seismic brace, which has the following beneficial effects:

[0016] (1) By setting a fixing component, this utility model can achieve clamping and fixing of pipes of different specifications and ensure that the pipe is stable enough, which is conducive to improving the adaptability of the support. The pipe is placed between two moving plates, then the second covering piece is wrapped around the outside of the pipe and then inserted into the inside of the top moving plate. Then the two first covering pieces are wrapped around the outside of the pipe and fixed inside the bottom moving plate. The screw is rotated by the wheel, and the support frame moves away from the pipe under the drive of the screw and the restriction of the two limit rods. As the tension increases, the second elastic covering piece will cover half or more of the pipe. Repeat the operation, and the two first covering pieces will wrap the other half or more of the pipe. With the cooperation of the two, the pipe will be firmly fixed.

[0017] (2) By setting up a shock-absorbing component, when the pipe moves downward due to vibration, the pipe drives the second covering plate and the moving plate to move downward. The moving plate drives the contact block to move synchronously, and the shock-absorbing pad is compressed under force. Due to its unique molecular structure and physical properties, it can convert mechanical vibration energy into heat energy or other forms of energy, thereby reducing vibration transmission. Conversely, when the pipe moves upward due to vibration, the two shock-absorbing pads at the bottom can also achieve the anti-vibration effect, which is beneficial to improving the anti-vibration effect of the support.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown in this embodiment, a single-tube seismic brace includes a mounting base 1 and two movable plates 401. Two horizontally arranged mounting plates 3 are fixedly connected to the outer wall of one side of the mounting base 1. The two movable plates 401 are equipped with fixing components 4, which include six connecting feet 402. The top two connecting feet 402 are slidably connected to the inside of the top movable plate 401, and the bottom four connecting feet 402 are slidably connected to the inside of the bottom movable plate 401. The top two connecting feet 402 are fixedly connected to the same covering piece 2 404, and the bottom two adjacent connecting feet 402 are fixedly connected to the same covering piece 1 403. An adjustment structure is installed inside each of the two mounting plates 3. The adjustment structure includes a support frame 405, a lead screw 406, and two limiting rods 407.

[0025] The lead screw 406 is threaded inside the mounting plate 3, and the two limit rods 407 are slidably inserted inside the mounting plate 3. The support frame 405 is rotatably connected to the end of the lead screw 406, and one end of each of the two limit rods 407 is fixedly connected to the outside of the support frame 405.

[0026] The pipe is placed between two movable plates 401. Then, the second covering piece 404 is wrapped around the outside of the pipe and inserted into the inside of the top movable plate 401. Next, the two first covering pieces 403 are wrapped around the outside of the pipe and fixed inside the bottom movable plate 401. The screw 406 is rotated by the wheel drive. The support frame 405 moves away from the pipe under the drive of the screw 406 and the restriction of the two limit rods 407. As the tension increases, the elastic second covering piece 404 will cover half or more of the pipe. The operation is repeated, and the two first covering pieces 403 will wrap the other half or more of the pipe. With the cooperation of the two, the pipe will be firmly fixed.

[0027] like Figure 2 and Figure 3 As shown, a shock-absorbing assembly 5 is installed between the movable plate 401 and the support frame 405. The shock-absorbing assembly 5 includes two placement chambers 501, which are fixedly connected to both sides of the bottom outer wall of the support frame 405. A shock-absorbing pad 502 is slidably inserted into each of the two placement chambers 501. A contact block 503 is fixedly connected to both sides of the bottom outer wall of the movable plate 401. The two contact blocks 503 are respectively attached to the top walls of the two shock-absorbing pads 502.

[0028] The support frame 405 has a limiting groove 504 on both sides of its interior. The outer wall of the two contact blocks 503 on the side away from each other is provided with a plug plate 505. The two plug plates 505 are slidably connected inside the two limiting grooves 504 respectively.

[0029] When the pipe moves downward due to vibration, the pipe causes the second covering plate 404 and the moving plate 401 to move downward. The moving plate 401 causes the contact block 503 to move synchronously, and the shock-absorbing pad 502 is compressed under force. Due to its unique molecular structure and physical properties, it can convert mechanical vibration energy into heat energy or other forms of energy, thereby reducing vibration transmission. Conversely, when the pipe moves upward due to vibration, the two shock-absorbing pads 502 at the bottom can also achieve the anti-vibration effect, which is beneficial to improving the anti-vibration effect of the support. When the pipe is subjected to force in the side, the second covering plate 404 is elastic and can deform with the movement of the pipe. The tension will be applied to the shock-absorbing pad 502 through the first covering plate 403, the second covering plate 404, the moving plate 401 and the contact block 503, and the shock-absorbing pad 502 will also be compressed, thereby achieving all-round vibration reduction.

[0030] like Figure 1 and Figure 2 As shown, the thread helix angle of the 406 lead screw is less than the equivalent friction angle to achieve a self-locking function and prevent the support frame from moving unexpectedly under vibration or other conditions.

[0031] like Figure 1 As shown, several reinforcing plates 2 are fixedly connected to the top and bottom outer walls of the two mounting plates 3. One end of each reinforcing plate 2 is fixedly connected to the outer wall of one side of the mounting base 1, which helps to improve the stability of the mounting plates 3 and prevents them from bending and deforming during use.

[0032] like Figure 1 and Figure 2 As shown, both the first cladding sheet 403 and the second cladding sheet 404 are made of mild steel, ensuring that they can deform and wrap around the pipe while also having sufficient strength.

[0033] This utility model provides a single-tube seismic brace, the specific working principle of which is as follows:

[0034] When the device is in operation, the pipe is placed between the two movable plates 401. Then, the second covering piece 404 is wrapped around the outside of the pipe and inserted into the inside of the top movable plate 401. Next, the two first covering pieces 403 are wrapped around the outside of the pipe and fixed inside the bottom movable plate 401. The screw 406 is rotated by the wheel drive. The support frame 405 moves away from the pipe under the drive of the screw 406 and the restriction of the two limit rods 407. As the tension increases, the elastic second covering piece 404 will cover half or more of the pipe. The operation is repeated, and the two first covering pieces 403 will wrap the other half or more of the pipe. With the cooperation of the two, the pipe will be firmly fixed. When the pipe moves downward due to vibration, the pipe causes the second covering plate 404 and the moving plate 401 to move downward. The moving plate 401 causes the contact block 503 to move synchronously, and the shock-absorbing pad 502 is compressed under force. Due to its unique molecular structure and physical properties, it can convert mechanical vibration energy into heat energy or other forms of energy, thereby reducing vibration transmission. Conversely, when the pipe moves upward due to vibration, the two shock-absorbing pads 502 at the bottom can also achieve the anti-vibration effect, which is beneficial to improving the anti-vibration effect of the support. When the pipe is subjected to force in the side, the second covering plate 404 is elastic and can deform with the movement of the pipe. The tension will be applied to the shock-absorbing pad 502 through the first covering plate 403, the second covering plate 404, the moving plate 401 and the contact block 503, and the shock-absorbing pad 502 will also be compressed, thereby achieving all-round vibration reduction.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
