Description

Technical Field

[0001] This utility model relates to the technical field of seismic fixing structures, and in particular to a seismic fixing structure for the top of a pipeline. Background Technology

[0002] In modern building design, especially in earthquake-prone areas, the seismic performance of pipeline systems is crucial. Therefore, developing a new type of seismic-resistant fixing structure for pipeline tops is of particular importance.

[0003] Currently, in existing pipeline seismic structures, such as the patent with authorization announcement number CN217762377U, this utility model discloses a pipeline seismic support with excellent seismic resistance, including a base, a first support frame is provided above the base, and a first extension plate is provided at both ends of the top of the first support frame. An auxiliary clamp is fixedly installed on the inner side of the first extension plate, and a buffer spring is welded to the bottom of the end face of the first support frame. The lower end of the buffer spring is welded to the top of the base.

[0004] However, during use, it was found that the stability and shock absorption of the support through springs were poor, which reduced the seismic resistance. Furthermore, the support provided poor protection for the top of the pipe, making it susceptible to damage from falling objects and reducing the reliability of the pipe's protection. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a seismic-resistant fixing structure for the top of a pipeline that reduces vibration damage to the pipeline, improves the stability of pipeline positioning, reduces impact damage to the pipeline from falling objects, and enhances the pipeline's protective effect.

[0006] This utility model discloses a seismic-resistant fixing structure for the top of a pipeline, comprising a base and two sets of first buffer blocks. The base has guide grooves, and the lower parts of both sets of first buffer blocks are slidably mounted on the guide grooves. It also includes a driving device, a supporting device, a buffer device, a second buffer block, a top buffer block, and a protective frame. The bottom end of the second buffer block is connected to the top end of the base and is positioned between the two sets of first buffer blocks. The base has a driving device for moving the two sets of first buffer blocks in opposite directions. The top end of the top buffer block is connected to the bottom end of the protective frame via the buffer device. The bottom end of the protective frame is mounted on the base via a supporting device, which supports the protective frame. The pipeline is then placed... The top buffer block is positioned at the top of the second buffer block. A drive device moves the two sets of first buffer blocks closer to each other, thereby supporting and fixing the two sets of first buffer blocks on both sides of the pipe. By bringing the bottom of the top buffer block into contact with the top of the pipe, and by limiting the position of the top buffer block through the protective frame, the top buffer block, together with the two sets of first and second buffer blocks, positions the pipe. When vibration occurs, the two sets of first buffer blocks, the second buffer block, and the top buffer block buffer the pipe, thereby reducing vibration damage to the pipe and improving the stability of the pipe's positioning. The protective frame protects the top of the pipe, thereby reducing the impact damage to the pipe from falling objects and improving the pipe's protective effect.

[0007] Preferably, the support device includes multiple sets of sleeves, multiple sets of support columns, multiple sets of first pistons, multiple sets of partitions, multiple sets of connecting rods, and multiple sets of second pistons. The bottom ends of the multiple sets of sleeves are all connected to the top end of the base. The lower parts of the multiple sets of support columns extend into the multiple sets of sleeves. A protective frame is installed on the upper part of the multiple sets of support columns. The multiple sets of first pistons are respectively installed at the bottom ends of the multiple sets of support columns. The multiple sets of first pistons are slidably disposed within the multiple sets of sleeves. The multiple sets of partitions are respectively installed on the inner sidewalls of the multiple sets of sleeves. The multiple sets of connecting rods slide through the multiple sets of partitions. The bottom ends of the multiple sets of first pistons are connected to the top ends of the multiple sets of second pistons through the multiple sets of connecting rods. The multiple sets of second pistons are slidably disposed within the multiple sets of sleeves. Inside the cylinder, multiple sets of second pistons are provided with through holes, and multiple sets of sleeves at the lower part of multiple sets of partitions are provided with damping fluid. Multiple sets of first pistons are supported by air on the upper and lower sides of the sleeves. When the protective frame vibrates, the multiple sets of first pistons move up and down in the upper part of the multiple sets of sleeves to compress the air, thereby causing the multiple sets of first pistons to buffer the protective frame through multiple sets of support columns. At the same time, the multiple sets of first pistons drive the multiple sets of second pistons to move up and down through multiple sets of connecting rods. After the multiple sets of second pistons move up and down, the damping fluid passes through the through holes of the multiple sets of second pistons, thereby damping the movement of the first pistons and improving the buffering stability of the protective frame.

[0008] Preferably, the driving device includes a motor and a lead screw. The motor is mounted on the outer wall of the base, and the output end of the motor is connected to the lead screw. The lead screw is rotatably mounted in the guide groove of the base, and the lower parts of the two sets of first buffer blocks are fitted onto the lead screw. The motor drives the lead screw to rotate, thereby driving the two sets of first buffer blocks to move in opposite directions.

[0009] Preferably, the buffer device includes multiple sets of telescopic rods and multiple sets of springs. The bottom end of the protective frame is connected to the top end of the top buffer block through multiple sets of telescopic rods, and multiple sets of springs are respectively fitted on the outer side walls of the multiple sets of telescopic rods. The multiple sets of telescopic rods and multiple sets of springs provide buffering between the protective frame and the top buffer block, thereby improving the shock resistance of the protective frame.

[0010] Preferably, it also includes a kit and a set screw. The kit is installed on the outer wall of the base, the lead screw rotates and extends into the kit, and the set screw is fitted onto the kit. By rotating the set screw to press the lead screw, the rotational positioning effect of the lead screw is improved, and the positional stability of the two sets of first buffer blocks is improved.

[0011] Preferably, it also includes anti-slip pads, which are disposed on the outer walls of the two sets of first buffer blocks; by providing two sets of anti-slip pads, the anti-slip effect between the pipe and the two sets of first buffer blocks is improved.

[0012] Preferably, the system also includes multiple sets of connectors and multiple sets of insert rods. The multiple sets of connectors are all installed on the outer wall of the base, and the multiple sets of insert rods pass through the multiple sets of connectors respectively. By inserting the multiple sets of insert rods into the ground, the positioning stability of the base is improved.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the pipeline is set at the top of the second buffer block, and the two sets of first buffer blocks are driven to move closer to each other by the driving device, so that the two sets of first buffer blocks support and fix the two sides of the pipeline. By making the bottom end of the top buffer block contact the top of the pipeline, and at the same time limiting the top buffer block by the protective frame, the top buffer block, together with the two sets of first buffer blocks and the second buffer block, positions the pipeline. When vibration occurs, the two sets of first buffer blocks, the second buffer block and the top buffer block buffer the pipeline, thereby reducing the vibration damage to the pipeline and improving the stability of the pipeline positioning. The protective frame protects the top of the pipeline, thereby reducing the impact damage to the pipeline from falling objects and improving the protection effect of the pipeline.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, this utility model discloses a seismic-resistant fixing structure for the top of a pipe, including a base 1 and two sets of first buffer blocks 2. The base 1 is provided with a guide groove, and the lower parts of the two sets of first buffer blocks 2 are slidably mounted on the guide groove. It also includes a driving device, a support device, a buffer device, a second buffer block 3, a top buffer block 4, and a protective frame 5. The bottom end of the second buffer block 3 is connected to the top end of the base 1, and the second buffer block 3 is disposed between the two sets of first buffer blocks 2. The base 1 is provided with a driving device, which is used to drive the two sets of first buffer blocks 2 to move in opposite directions. The top end of the top buffer block 4 is connected to the bottom end of the protective frame 5 through the buffer device. The bottom end of the protective frame 5 is mounted on the base 1 through the support device, which is used to support the protective frame 5.

[0023] like Figure 3As shown, the support device includes multiple sets of sleeves 6, multiple sets of pillars 7, multiple sets of first pistons 8, multiple sets of partitions 9, multiple sets of connecting rods 10, and multiple sets of second pistons 11. The bottom ends of the multiple sets of sleeves 6 are all connected to the top end of the base 1. The lower parts of the multiple sets of pillars 7 extend into the multiple sets of sleeves 6 respectively. The protective frame 5 is installed on the upper part of the multiple sets of pillars 7. The multiple sets of first pistons 8 are respectively installed at the bottom ends of the multiple sets of pillars 7. The multiple sets of first pistons 8 are respectively slidably arranged in the multiple sets of sleeves 6. The multiple sets of partitions 9 are respectively installed on the inner sidewalls of the multiple sets of sleeves 6. The multiple sets of connecting rods 10 slide through the multiple sets of partitions 9. The bottom ends of the multiple sets of first pistons 8 are connected to the top ends of the multiple sets of second pistons 11 through the multiple sets of connecting rods 10. The multiple sets of second pistons 11 are slidably arranged in the multiple sets of sleeves 6. The multiple sets of second pistons 11 are provided with through holes, and the multiple sets of sleeves 6 at the lower part of the multiple sets of partitions 9 are provided with damping fluid.

[0024] In this embodiment, the pipeline is positioned at the top of the second buffer block 3. A driving device moves the two sets of first buffer blocks 2 closer to each other, thereby supporting and fixing the two sets of first buffer blocks 2 on both sides of the pipeline. The bottom end of the top buffer block 4 contacts the top of the pipeline, and the protective frame 5 limits the position of the top buffer block 4. Thus, the top buffer block 4, together with the two sets of first buffer blocks 2 and the second buffer block 3, positions the pipeline. When vibration occurs, the two sets of first buffer blocks 2, the second buffer block 3, and the top buffer block 4 buffer the pipeline, thereby reducing vibration damage to the pipeline and improving the stability of the pipeline positioning. The protective frame 5 protects the top of the pipeline, thereby reducing the impact damage to the pipeline from falling objects and improving the pipeline's protective effect.

[0025] Example 2

[0026] Based on Example 1, such as Figure 4 As shown, this utility model provides a pipe top anti-seismic fixing structure. The driving device includes a motor 12 and a lead screw 20. The motor 12 is installed on the outer wall of the base 1. The output end of the motor 12 is connected to the lead screw 20. The lead screw 20 is rotatably installed in the guide groove of the base 1. The lower parts of two sets of first buffer blocks 2 are fitted onto the lead screw 20.

[0027] like Figure 2 As shown, the buffer device includes multiple sets of telescopic rods 13 and multiple sets of springs 14. The bottom end of the protective frame 5 is connected to the top end of the top buffer block 4 through multiple sets of telescopic rods 13, and multiple sets of springs 14 are respectively fitted on the outer side wall of multiple sets of telescopic rods 13.

[0028] like Figure 1 As shown, it also includes a kit 15 and a set screw 16. The kit 15 is mounted on the outer wall of the base 1, the lead screw 20 rotates and extends into the kit 15, and the set screw 16 is fitted onto the kit 15.

[0029] like Figure 4As shown, it also includes an anti-slip pad 17, which is disposed on the outer side wall of the two sets of first buffer blocks 2;

[0030] like Figure 2 As shown, it also includes multiple sets of connectors 18 and multiple sets of plug rods 19. The multiple sets of connectors 18 are all installed on the outer side wall of the base 1, and the multiple sets of plug rods 19 pass through the multiple sets of connectors 18 respectively.

[0031] In this embodiment, multiple sets of first pistons 8 are supported by air on the upper and lower sides of the sleeve 6. When the protective frame 5 vibrates, the air is compressed by the up and down movement of the multiple sets of first pistons 8 in the upper part of the multiple sets of sleeves 6. This causes the multiple sets of first pistons 8 to buffer the protective frame 5 through the multiple sets of support columns 7. At the same time, the multiple sets of first pistons 8 drive the multiple sets of second pistons 11 to move up and down through the multiple sets of connecting rods 10. After the multiple sets of second pistons 11 move up and down, the damping fluid passes through the through holes of the multiple sets of second pistons 11, thereby damping the movement of the first pistons 8 and improving the buffering stability of the protective frame 5. The motor 12 drives the lead screw 20 to rotate, causing the lead screw 20 to drive the two sets of first buffer blocks 2 to move in opposite directions.

[0032] This utility model discloses a seismic-resistant fixing structure for the top of a pipeline. In operation, the pipeline is placed on top of the second buffer block 3. A driving device drives two sets of first buffer blocks 2 to move closer to each other, thereby supporting and fixing the two sides of the pipeline. The bottom end of the top buffer block 4 contacts the top of the pipeline, and the protective frame 5 limits the position of the top buffer block 4. Thus, the top buffer block 4, together with the two sets of first buffer blocks 2 and the second buffer block 3, positions the pipeline. When vibration occurs, the two sets of first buffer blocks 2, the second buffer block 3 and the top buffer block 4 buffer the pipeline, and the protective frame 5 protects the top of the pipeline.

[0033] The motor 12 of the anti-seismic fixing structure at the top of the pipe of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
