Description

Technical Field

[0001] This utility model relates to the field of HVAC piping technology, and in particular to a pipe support device for HVAC equipment. Background Technology

[0002] HVAC ducts have a very wide range of applications, including air supply and return ducts for purification systems, ventilation ducts for central air conditioning systems, ventilation ducts for industrial air supply and exhaust systems, air intake and exhaust ducts for environmental protection systems, gas extraction pipes for mines, and plastic-coated ventilation ducts for mines.

[0003] In various applications of HVAC ductwork, pipes need to be laid, requiring the use of supports. These supports must meet specific functional requirements depending on the pipe laying environment. Generally, for longer pipe laying distances, the support height at all support points needs to be consistent. Initially, supports must be fixed at the same height, with minor adjustments made later during pipe laying to ensure proper pipe tightening and prevent damage while maintaining stable support. However, conventional clamp (ring) type pipe supports cannot simultaneously adjust the pipe support height and clamp tightness, resulting in an imbalance between support and clamp fixation, which can easily damage the pipe and compromise support stability.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a pipe support device for HVAC equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a support device for HVAC equipment pipes in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a pipe support device for HVAC equipment, comprising:

[0008] A fixed upright plate is fixedly connected to a vertical wall surface, and a horizontal support plate is provided on the front side of the fixed upright plate;

When the steel strip is tightened, the steel strip located between the two sets of cylindrical support members is used to support the pipeline.

[0010] A tension adjustment mechanism is provided on the horizontal support plate to adjust the tension of the steel strip located between the two sets of cylindrical supports.

[0011] And an upper clamping mechanism, which is used to press and cover the top of the pipe to fix the pipe.

[0012] Furthermore, a triangular reinforcing rib is connected between the lower surface of the horizontal support plate and the fixed upright plate.

The two ends of the steel strip passing through the guide hole are respectively fixedly connected to the two ends of the adjustment block and form a closed ring structure with the adjustment block.

[0016] The adjusting block is provided with a first tightening bolt that is threaded to it, and the first tightening bolt passes through the adjusting block and is tightened against the lower surface of the horizontal support plate.

[0017] Furthermore, the horizontal support plate is provided with four second tightening bolts that are threadedly engaged with it. The second tightening bolts pass through the horizontal support plate and are tightened against the upper surface of the adjusting block.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-2 A heating, ventilation, air conditioning (HVAC) equipment pipe support device, comprising:

[0029] A fixed vertical plate 1 is fixedly connected to a vertical wall. A horizontal support plate 2 is installed on the front side of the fixed vertical plate 1. The fixed vertical plate 1 and the horizontal support plate 2 serve as the supporting foundation for the HVAC equipment pipes and are used to fix them to the wall where the pipes are laid in order to stably support the pipes.

[0030] A steel strip 3, in a closed loop shape, is mounted on a horizontal support plate 2. Two sets of cylindrical support members 4 are horizontally arranged on the upper surface of the horizontal support plate 2, parallel to each other. The steel strip 3 is mounted on the two sets of cylindrical support members 4. Specifically, the surface of the steel strip 3 makes surface contact with the cylindrical surface of the cylindrical support member 4 and slides on the cylindrical surface of the cylindrical support member 4. When the steel strip 3 is tensioned, the steel strip 3 located between the two sets of cylindrical support members 4 is used to support the pipeline. Because the steel strip 3 needs to support... The pipeline has a certain support surface. Therefore, the steel strip 3 supporting the pipeline, that is, the steel strip 3 between the two sets of cylindrical support members 4, has a certain curvature when supporting the pipeline. Moreover, the two sets of cylindrical support members 4 do not directly bear the pressure of the pipeline. Therefore, when adjusting the tightness of the steel strip 3 in the position supporting the pipeline, the curvature of the steel strip 3 supporting the pipeline will be changed. When the curvature changes, the support height of the pipeline will also change accordingly, thereby realizing the fine adjustment of the support height of the pipeline, so that the support force of this device on each support point of the pipeline is balanced.

[0031] The tension adjustment mechanism is set on the horizontal support plate 2 to adjust the tension of the steel strip 3 located between the two sets of cylindrical support members 4. Specifically, by adjusting the tension of the steel strip 3 at the lower end, the curvature of the steel strip 3 at the upper end, that is, the position supporting the pipe, is adjusted.

[0032] The upper clamping mechanism is used to press and cover the pipe to fix it in place. That is, the pipe is tightened and fixed by the cooperation of the steel band 3 and the upper clamping mechanism. In specific operation, the upper clamping mechanism can be tightened and fixed first, and then the support height and tightness of the steel band 3 on the pipe can be adjusted.

[0033] Furthermore, a triangular reinforcing rib 5 is connected between the lower surface of the horizontal support plate 2 and the fixed vertical plate 1 to increase structural stability and ensure the stability of the horizontal support plate 2 in supporting the pipeline.

[0034] Furthermore, the steel strip 3 supporting the pipeline has an arc shape below the pipeline to achieve surface contact support between the steel strip 3 and the pipeline, ensuring the stability of the pipeline support.

[0035] Furthermore, the horizontal support plate 2 is provided with two sets of guide holes 6 to allow the two ends of the steel strip 3 to pass through and extend below the horizontal support plate 2, so as to facilitate the installation of a tension adjustment mechanism and adjust the tension of the steel strip 3 at the upper end.

[0036] Furthermore, the tensioning adjustment mechanism includes an adjustment block 7, which is located below the horizontal support plate 2. The two ends of the steel strip 3 passing through the guide hole 6 are respectively fixedly connected to the two ends of the adjustment block 7 and form a closed ring structure with the adjustment block 7.

[0037] The adjusting block 7 is provided with a first tightening bolt 8 that is threadedly engaged with it. The first tightening bolt 8 passes through the adjusting block 7 and is tightened against the lower surface of the horizontal support plate 2.

[0038] Specifically, the steel belt 3 carrying the pipe will pull the adjusting block 7 upward, while the first tightening bolt 8 is tightened against the lower surface of the horizontal support plate 2. Therefore, by rotating the threaded connection between the first tightening bolt 8 and the adjusting block 7, the length of the first tightening bolt 8 being pushed out is adjusted axially, thereby adjusting the length of the steel belt 3 being pulled downward by the adjusting block 7, so as to adjust the support height of the upper part of the steel belt 3 on the pipe.

[0039] Furthermore, the horizontal support plate 2 is provided with four second tightening bolts 9 that are threaded together. The second tightening bolts 9 pass through the horizontal support plate 2 and are tightened against the upper surface of the adjusting block 7. The four second tightening bolts 9 are distributed at the four corners of the adjusting block 7. In order to prevent the first tightening bolt 8 from loosening due to vibration or other reasons, the adjusting block 7 is further fixed by the four second tightening bolts 9 simultaneously, so as to maintain the positional stability of the adjusting block 7 after adjustment, that is, to ensure the stability of the tension of the steel strip.

[0040] Furthermore, the upper clamping mechanism includes an upper pressure plate 10, with an arc-shaped segment 11 corresponding to the curved surface of the pipe at its center. One end of the upper pressure plate 10 is hinged to the fixed vertical plate 1 above the horizontal support plate 2, and the other end is fixedly connected to the horizontal support plate 2 by fastening bolts 12. Specifically, the arc-shaped segment 11 of the upper pressure plate 10 forms surface contact with the pipe to cooperate with the steel band 3 to tighten and fix the pipe. The hinged end of the upper pressure plate 10 allows for quick operation when fixing the pipe, and the other end is fixed to the horizontal support plate 2 by fastening bolts 12. The upper pressure plate 10, with the pipe secured, remains basically horizontal, and even minor adjustments to the pipe support height by the steel band 3 do not affect the connection of the fastening bolts 12 between the upper pressure plate 10 and the horizontal support plate 2.

[0041] Furthermore, guide posts 13 are provided on the upper surface of the horizontal support plate 2 at the positions corresponding to the fastening bolts 12. The guide posts 13 allow the fastening bolts 12 to pass through. The gap between the guide posts 13 and the fastening bolts 12 should not be too small to ensure that the fastening bolts 12 have a certain degree of freedom in the vertical direction. However, the guide posts 13 also serve to guide the fastening bolts 12 and protect the external threads of the fastening bolts 12. More importantly, they reduce the damage to the fastening bolts 12 caused by radial forces.

[0042] In summary, this device uses a steel strip in conjunction with an upper clamping mechanism to tighten and fix the pipeline, and combines this with a horizontal support plate to support the pipeline. The steel strip is the stress-bearing part supporting the pipeline, and the tension of the steel strip is adjusted by a tension adjustment mechanism. In other words, the curvature of the part of the steel strip supporting the pipeline is adjusted to coordinate with the upper clamping mechanism to adjust the tightness of the pipeline. It also allows for fine-tuning of the pipeline support height. Using this device, the support and tightness of HVAC equipment pipelines can achieve a better balance, resulting in more stable pipeline support.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
