Description

Technical Field

[0001] This invention relates to the field of fixed structure technology, and particularly to pipeline fixing devices and refrigeration equipment. Background Technology

[0002] Currently, most compressor systems address excessive vibration in the moving pipe by binding the moving pipe and stationary pipe together with pipe fixing blocks to limit the vibration displacement of the moving pipe. This method of using pipe fixing blocks is practical and effective. However, in actual use, due to the different pipe diameters and pipe gaps of various products, many types of pipe fixing blocks are required, which increases the mold opening cost of pipe fixing block production. Furthermore, different models of pipe fixing blocks cause material clutter and make storage and classification difficult.

[0003] For example, the patent with publication number CN114877154A discloses a pipeline vibration damping device that can adjust the length to adapt to pipelines with different pipe gaps, but cannot adapt to pipelines with different diameters. The effect of adding damping particles is highly dependent on manual operation, and the structure is relatively complex and the manufacturing cost is high, making it unsuitable for mass-produced products. Summary of the Invention

[0004] To address the problem of poor adaptability of pipeline fixing equipment, this invention proposes a pipeline fixing device that can adjust the spacing of the clamping parts according to the pipeline spacing, thereby adapting to the use of pipelines with different spacings and improving adaptability.

[0005] The technical solution adopted in this invention is to design a pipeline fixing device for fixing two pipelines relative to each other, including a bracket located between the two pipelines, and two fixing clips provided on the bracket for clamping the two pipelines respectively. The two fixing clips are controlled by a spacing adjustment mechanism to be relatively close or far apart between the two pipelines.

[0006] In some embodiments, the spacing adjustment mechanism includes a track disposed on a bracket along the moving direction of the two fixed clamps, the fixed clamps slidingly engaging on the track, and a positioning mechanism disposed between the fixed clamps and the track, the positioning mechanism fixing the fixed clamps relative to the track.

[0007] In some embodiments, the track is a slide groove, the positioning mechanism includes a guide rod fixedly connected to the fixing clamp, the guide rod is slidably engaged with the slide groove, the guide rod is threaded, and nuts are provided on both sides of the slide groove on the guide rod.

[0008] In some embodiments, there are two slides, which are located on both sides of the fixing clamp. Each side of the fixing clamp has a guide rod that mates with the slide, and a nut is fitted on each guide rod.

[0009] In some embodiments, the bracket includes triangular ends located on both sides of the fixing clamp, and each triangular end has a sliding groove corresponding to each fixing clamp. The sliding groove is a through groove along the length of the guide rod, and the guide rod passes through the through groove. The end of the guide rod that exits the through groove is fitted with a nut.

[0010] In some embodiments, the fixing clamp includes two opposing clamping parts, which are rotatably connected by a shaft hinge, and the guide rod is the pivot of the shaft hinge.

[0011] In some embodiments, the guide rod is provided with a limiting block that slides with the slide groove, and the limiting block and the nut clamp the guide rod on the slide groove and fix it in place.

[0012] In some embodiments, the fixing clamp includes two opposing clamping portions, and the two clamping portions are provided with opposing through holes.

[0013] In some embodiments, the through holes of the two fixing clips are connected by a strapping tape.

[0014] Refrigeration equipment, including the aforementioned pipe fixing device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes two clamps on a support to hold two pipes respectively. The clamps are adjusted in position relative to each other via a spacing adjustment mechanism, allowing for connection and fixation of pipes with varying spacing, thus improving adaptability. The support includes triangular ends on both sides of the clamps to prevent them from getting too close. A guide rod is used as the pivot point of the hinge, ensuring a simple, compact, easy-to-use, and low-cost device without affecting the clamping function. The through holes of the two clamps are connected by a strapping band, preventing them from moving away from each other. This combination of clamping and strapping securely fixes the pipes, ensuring a secure and convenient connection. Attached Figure Description

However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention covered by the claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the inventive solution.

[0032] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] Example

[0034] Moving pipes and stationary pipes in a compressor play a crucial role in air compression and mechanical operation. They are key components within the compressor, responsible for controlling gas flow and pressure increases. Moving pipes typically refer to the pipes through which gas enters and exits the compressor, responsible for introducing gas and outputting compressed gas. In the moving pipes, the gas gains kinetic energy due to the compressor's operation, causing it to flow and be transported throughout the system. Stationary pipes, on the other hand, are pipes inside the compressor used to store or slow gas flow. Stationary pipes are sometimes also used to balance pressure or regulate gas flow rate to ensure system stability during compressor operation. These two types of pipes work together in the compressor's operation to ensure that gas is properly compressed and delivered. Their design and placement vary depending on the type and application of the compressor, but their primary function is to control gas flow and pressure.

[0035] When a compressor is subjected to an unbalanced load, it can cause vibration in both the moving and stationary pipes. This can be due to malfunctions in other components of the system or uneven gas flow. Mechanical problems within the compressor, such as loose, damaged, or worn parts, can also cause vibration in the moving or stationary pipes. Vibrations in the surrounding environment or from other mechanical equipment can be transmitted to the moving and stationary pipes through connecting parts, causing them to vibrate. Sometimes, instability in the gas itself can also cause pipe vibration, especially when the compressor is running and gas flow is suddenly obstructed or encounters reverse flow. Improper installation, securing, or support systems can expose the pipes to additional vibration or pressure, leading to vibration problems.

[0036] Continuous pipe vibration can cause loosening, wear, or damage to mechanical parts at or near pipe joints, potentially affecting the pipe's seal or strength and leading to leaks or malfunctions.

[0037] Pipe vibration can cause damage or malfunction to other components of the system, especially those that are directly connected to or near the compressor.

[0038] Pipeline vibration may increase the pressure inside the system, leading to unexpected leaks or sudden system failures, which may pose safety risks to the surrounding environment or personnel.

[0039] Continuous vibration can affect the performance of the compressor, leading to reduced energy efficiency, decreased production capacity, or unstable system operation.

[0040] Frequent vibrations can cause pipes and related components to wear out faster, potentially requiring more frequent maintenance and replacement of parts, thus increasing maintenance costs.

[0041] Currently, most compressor systems address excessive vibration in the moving pipe by binding the moving pipe and stationary pipe together with pipe fixing blocks to limit the vibration displacement of the moving pipe. This method of using pipe fixing blocks is practical and effective. However, in actual use, due to the different pipe diameters and pipe gaps of various products, many types of pipe fixing blocks are required, which increases the mold opening cost of pipe fixing block production. Furthermore, different models of pipe fixing blocks cause material clutter and make storage and classification difficult.

[0042] Therefore, such as Figure 1 , 2 As shown, a pipe fixing device for refrigeration equipment is proposed for fixing two pipes 11 relative to each other. It includes a bracket 1 located between the two pipes 11. The bracket 1 is provided with two fixing clips 2 for clamping the two pipes 11 respectively. The two fixing clips 2 are controlled by a spacing adjustment mechanism to be relatively close or far apart between the two pipes 11, so as to be suitable for connecting and fixing pipes 11 with different spacings, thereby adapting to the use of pipes 11 with different spacings and improving adaptability.

[0043] The spacing adjustment mechanism includes a track arranged on the bracket 1 along the moving direction of the two fixed clamps 2. The fixed clamps 2 are slidably engaged on the track. A positioning mechanism is provided between the fixed clamps 2 and the track. The positioning mechanism fixes the fixed clamps 2 relative to the track, thereby allowing the fixed clamps 2 to adjust the spacing along the track. After adjusting to a suitable spacing, the fixed clamps 2 are fixed relative to the track, thus achieving spacing fixation.

[0044] like Figure 3 As shown, the track is a slide groove 101, and the positioning mechanism includes a guide rod 3 fixedly connected to the fixing clamp 2. The guide rod 3 is slidably engaged with the slide groove 101. The guide rod 3 is threaded and has nuts 4 located on both sides of the slide groove 101. By tightening the nuts 4, the guide rail is clamped and fixed on the slide groove 101, which is simple and convenient.

[0045] Specifically, in this embodiment, there are two slide grooves 101, which are located on both sides of the fixing clamp 2. Each side of the fixing clamp 2 has a guide rod 3 that cooperates with the slide groove 101. Nuts 4 are fitted on the guide rods 3 on both sides, so that both sides of the fixing clamp 2 are fixed to the corresponding slide grooves 101 by the guide rods 3, thus making the fixing clamp 2 firmly fixed.

[0046] The bracket 1 includes triangular ends located on both sides of the fixing clips 2. Each triangular end has a corresponding sliding groove 101 on both sides. The sliding groove 101 is a through groove along the length of the guide rod 3. The guide rod 3 passes through the through groove, and a nut 4 is fitted to the end of the guide rod 3 that exits the through groove. The triangular ends cause the length of the sliding groove 101 to vary along the length of the guide rod 3; that is, the depth of the sliding groove 101 decreases continuously from the middle to both sides along the length of the guide rod 3. This prevents the nuts 4 at both ends of the guide rod 3 from moving towards the triangular ends, thus preventing the nuts 4 from moving towards the middle. In other words, the distance between the two fixing clips 2 cannot decrease, preventing the two fixing clips 2 from getting too close to each other.

[0047] like Figure 4 , 5 As shown in Figure 6, the fixing clamp 2 includes two opposing clamping parts, which are rotatably connected by a shaft hinge. The guide rod 3 is the hinge axis of the shaft hinge. In this way, without affecting the positioning function of the fixing clamp 2 using the guide rod 3, the structure of the fixing clamp 2 is simplified, ensuring that the fixing clamp 2 is firmly positioned and firmly clamps and fixes the pipeline 11. The fixing between the two sides of the hinge axis does not affect the clamping function of the fixing clamp 2, making the device simple and compact in structure, easy to use, and low in cost.

[0048] The guide rod 3 is provided with a limiting block 301 that slides with the slide groove 101. The limiting block 301 and the nut 4 clamp the guide rod 3 on the slide groove 101 and fix it. The limiting block 301 restricts the movement of the fixing clamp 2 along the length direction of the guide rod 3, so that it can only move and adjust in the direction of the distance between the two fixing clamps 2. At the same time, it also guides the movement of the guide rod 3 in the slide groove 101.

[0049] The fixing clip 2 includes two opposing clamping parts, that is, two parts of the fixing clip 2 that open and close relative to each other. The two clamping parts are open so that they can clamp onto the pipe 11. The two clamping parts are provided with opposing through holes 203, so that the pipe 11 can be tied together with the clamping parts by passing the strapping 5 through the through holes 203.

[0050] like Figure 7 , 8 As shown in Figures 9 and 10, the through holes 203 of the two fixing clips 2 can also be connected together by a cable tie 5, thereby preventing the two fixing clips 2 from moving away from each other. Of course, the cable tie can also be replaced by bolts or other fastening methods.

[0051] Pipeline strapping is a device used to secure and bind pipes, typically made of durable plastic or nylon. These straps play a role in securing compressor piping. The straps must be able to withstand the weight and pressure of the pipes and remain stable during compressor operation. Choosing high-quality, durable strapping is crucial to ensure long-term stable pipe securing. When using strapping to secure pipes, ensure proper binding and securing; avoid over-tightening or under-tightening. Over-tightening may damage the pipes, while under-tightening will not effectively secure them and can cause vibration and movement. Compressor piping may be affected by temperature changes during operation; therefore, the selection and use of strapping must consider the thermal expansion and contraction of the pipes to prevent loosening or over-tightening due to temperature variations. Straps wear down over time, so regular inspection and timely replacement of damaged or aged strapping are necessary to ensure pipe stability.

[0052] Specifically, the two opposing clamping parts are an upper clamping plate 201 and a lower clamping plate 202. The ends of the upper clamping plate 201 and the lower clamping plate 202 are respectively provided with coaxially opposite cylinders. These cylinders are respectively connected to the guide rod 3. One cylinder is provided with a rotating shaft 6, and the other cylinder is provided with a shaft hole 7 that rotatably engages with the rotating shaft 6. A pin hole 8 is perpendicularly connected to the shaft hole 7, and a pin 9 is inserted into the pin hole 8. The rotating shaft 6 is provided with an annular groove 601 that slidably engages with the end of the pin 9. The pin 9 prevents the rotating shaft 6 from axially disengaging from the shaft hole 7. The rotatable engagement of the rotating shaft 6 with the shaft hole 7 allows the upper clamping plate 201 and the lower clamping plate 202 to rotate relative to each other, thereby opening or closing the clamping part of the fixing clamp 2.

[0053] When in use, first attach anti-abrasion rubber 10 to the two pipes that need to be fixed, clamp the two pipes with the left and right end clips respectively and tie them tightly with the strapping 5. After tightening in place, tighten the stop nut 4 to prevent the clips from falling back, and tie the left and right fixing clips 2 with the strapping 5 to improve the overall rigidity of the device.

[0054] like Figure 11 , 12 As shown, the device utilizes the guide rods of the upper and lower clamps 202 to slide left and right on the slide groove 101 to achieve variable distance, and utilizes the V-shaped structure formed by the two clamps to adapt to different pipe diameters.

[0055] A clamp with two opposing clamping plates is typically a fixture or fixing device used to hold or secure pipes or other components. This design plays a crucial role in compressor piping fixation, ensuring the pipes are securely and firmly fixed, preventing movement or swaying. This type of clamp generally consists of two clamping plates, facing each other on both sides, secured by bolts or other connection methods. They create a clamping force on both sides of the pipe or between two components, ensuring pipe stability, and the clamping force can be adjusted to accommodate pipes of different diameters or sizes. The two opposing clamping plates provide a more uniform clamping force, ensuring a firm fixation and preventing movement or swaying. Adjustable designs may be available, allowing adjustment based on pipe size or required fixing force, suitable for pipes of different specifications or diameters. It can be used to fix various pipes, equipment, or components, providing an effective clamping and fixing method. Generally, this type of clamp is relatively simple, and installation and adjustment are relatively convenient. Using this type of clamp with two opposing clamping plates in compressor piping fixation effectively ensures the secure fixation of the pipes, preventing wear, leakage, or other problems caused by vibration or movement. The correct selection and use of clamps, and ensuring their secure installation, are crucial for the stability and safety of pipelines.

[0056] Anti-abrasion rubber pads are commonly used as gaskets or shims in pipe fixing to prevent direct contact between the pipe and the support or fixed equipment during the fixing process, thereby reducing wear and friction. They can also be used as shock-absorbing pads to help absorb vibrations and shocks generated by pipes or equipment during operation. Choose wear-resistant, corrosion-resistant, and high-temperature-resistant materials to ensure long-term stability and durability, preventing rapid wear or aging due to compressor operation. Ensure the selected anti-abrasion rubber pads have appropriate thickness and size to provide good cushioning and protection while meeting pipe fixing requirements. Anti-abrasion rubber pads need to have a certain degree of anti-slip properties to ensure the pipe does not easily move or slide during fixing. They should also have a certain degree of shock absorption to help absorb vibrations and shocks. Anti-abrasion rubber pads can be installed between the pipe and the support or fixed equipment using appropriate fixing methods, such as bolt fixing or other suitable methods, to ensure the pads firmly clamp the pipe and effectively prevent wear.

[0057] Using anti-abrasion rubber pads to secure compressor piping can protect the pipes and reduce wear, but it is equally important to ensure proper installation and selection to provide the best protection.

[0058] For pipe connections with varying spacing, the design ensures adjustable spacing between two clamps. This design accommodates pipe connections of different sizes or spacings, allowing the clamps to be flexibly adjusted to fit different pipe configurations. The clamp design must allow for adjustable spacing between the two clamps, enabling relative movement to accommodate different pipe spacings. During spacing adjustment, it's crucial to ensure the clamps remain stable and secure in different positions. After adjustment, the clamps must be retightened to ensure a secure pipe connection. This clamp design should possess sufficient applicability and flexibility to adapt to various pipe spacings, making it more practical in real-world applications. The adjustable spacing clamp design provides greater flexibility during pipe connection, allowing a single clamp to accommodate different spacings. This design facilitates installation and maintenance while reducing the need for multiple clamps of different sizes.

[0059] Of course, this embodiment can also be applied to the pipe fixing of other refrigeration equipment. The fixing of internal pipes in refrigeration equipment is crucial for the stability and performance of the system; these are the main devices used to support the pipes. Brackets are typically fixed to the structure of the equipment or walls to ensure the pipes remain stable and can withstand the weight of the fluid inside. In refrigeration equipment, vibration and shock can damage the pipes or affect the operation of the refrigeration system. Using vibration damping devices or shock absorbers can help reduce these adverse effects, absorb vibrations, and reduce the forces transmitted to the pipes.

[0060] Maintaining the stability and reliability of the internal piping of refrigeration equipment is crucial for the normal operation of the system. Therefore, ensuring the selection of appropriate support and fixing devices during piping installation, and conducting regular inspections and maintenance, are key to ensuring the long-term stable operation of the refrigeration system.
