Description

Technical Field

[0001] This utility model relates to the field of pipe support technology, and in particular to a heating and ventilation pipe installation support for heating and ventilation engineering. Background Technology

[0002] The weight of the pipeline itself and the fluid inside it needs to be supported by supports to transfer this weight to the building structure, preventing the pipeline from sagging, deforming, or even breaking due to gravity. This ensures the stability and safety of the pipeline system, fixes the pipeline in the designed position, and prevents the pipeline from shifting or shaking due to factors such as medium flow, vibration, and thermal expansion and contraction during operation. For pipeline systems that vibrate, such as chilled water pipelines and water pump connection pipelines in air conditioning systems, supports can play a role in vibration isolation and damping, limiting the vibration of the pipeline to a certain range, reducing the impact of vibration on the surrounding environment and buildings, and also reducing the possibility of fatigue damage to the pipeline due to vibration.

[0003] However, existing technologies, such as Chinese Publication No. CN219095010U, "A HVAC Pipe Installation Bracket for HVAC Engineering," which relates to the field of HVAC engineering technology, disclose a HVAC pipe installation bracket for HVAC engineering. This bracket includes a base plate, with an adjustment mechanism and a clamping mechanism positioned above the base plate. The clamping mechanism is located above the adjustment mechanism. The adjustment mechanism includes a power unit and an adjustment section, with the adjustment section located to the left of the power unit. The power unit includes a motor and a double-threaded rod, with the left end face of the motor output rod fixedly connected to the right end face of the double-threaded rod. The adjustment section includes a slider, a fixed seat, and a support rod. The adjustment mechanism allows the fixed seat to be adjusted vertically to different heights, facilitating the connection and installation of HVAC pipes, reducing the need for simple scaffolding, and improving the efficiency of HVAC pipe installation. The clamping mechanism clamps the HVAC pipes.

[0004] However, this device does not have a bidirectional vibration damping and waterproof hammer structure, so it cannot effectively absorb and dissipate vibration energy in both horizontal and vertical directions. This increases the vibration amplitude of the pipeline, leading to fatigue damage and loosening of connections due to long-term vibration, reducing the service life of the pipeline system, increasing the noise generated by pipeline vibration, failing to improve the comfort of the working and living environment, and failing to guarantee the stability and safety of the entire system. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the prior art, such as the inability to effectively absorb and dissipate vibration energy in both horizontal and vertical directions, which increases the vibration amplitude of the pipeline, leading to fatigue damage and loosening of connections due to long-term vibration, reducing the service life of the pipeline system, increasing the noise generated by pipeline vibration, failing to improve the comfort of the working and living environment, and failing to guarantee the stability and safety of the entire system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heating and ventilation pipe installation bracket for heating and ventilation engineering, comprising a main housing, wherein a positive and negative threaded rod is rotatably connected inside the main housing and extends out at one end, and two internal threaded blocks are threadedly connected to the outer surface of the positive and negative threaded rod, a first shaft block is fixedly connected to the bottom of the internal threaded block, a first connecting rod is rotatably connected inside the first shaft block, a second shaft block is rotatably connected to the end of the first connecting rod away from the first shaft block, a clamping plate is fixedly connected to one side of the second shaft block, a rotating rod is fixedly embedded at one end of the clamping plate, and the two ends of the two rotating rods are rotatably connected to the inside of the main housing, and a limit component is provided on the outer surface of the internal threaded block, wherein when the internal threaded block moves, it drives one end of the first connecting rod through the first shaft block, and the other end of the first connecting rod drives the clamping plate through the second shaft block.

[0007] In a preferred embodiment, the limiting component includes a limiting plate, the bottom of which is fixedly connected to the top of the internal threaded block. A limiting groove is formed on the top of the inner surface of the main housing. The outer surfaces of the two limiting plates are movably embedded in the limiting groove. The limiting plate on the top of the internal threaded block can only move along the groove opening direction.

[0008] In a preferred embodiment, the limiting assembly further includes limiting sleeves, one side of which is fixedly connected to the outer surface of the internal threaded block. Limiting rods are movably embedded in the inner surfaces of the two limiting sleeves, and the two ends of the limiting rods are fixedly connected to the inner surface of the main housing. When the internal threaded block moves, the limiting sleeves can only move in the axial direction of the limiting rods, thereby driving the two internal threaded blocks to move away from or closer to each other along the axial direction of the limiting rods.

[0009] In a preferred embodiment, a rotating block is fixedly connected to one end of the forward and reverse lead screw, and a rocker arm is movably embedded inside the rotating block. The rocker arm and the rotating block drive the forward and reverse lead screw to rotate inside the main housing.

[0010] In a preferred embodiment, a fixing member is fixedly connected to the top of the main housing, and a damping rod is fixedly connected inside the fixing member. Two damping sleeves are movably sleeved on the outer surface of the damping rod. When the damping sleeves move on the outer surface of the damping rod, they will dissipate vibration energy through damping.

[0011] In a preferred embodiment, a third shaft block is fixedly connected to the top of the damping sleeve, and a second connecting rod is rotatably connected inside the third shaft block. The other end of the second connecting rod will drive the damping sleeve to move away from or towards each other on the outer surface of the damping rod through the third shaft block.

[0012] In a preferred embodiment, a fourth shaft block is rotatably connected to the end of the second connecting rod away from the third shaft block, and a mounting plate is fixedly connected to the top of the two fourth shaft blocks. The fourth shaft block at the bottom of the mounting plate will drive one end of the second connecting rod.

[0013] In a preferred embodiment, two springs are movably sleeved on the outer surface of the damping rod. One end of the spring is fixedly connected to the inner side of the fixing member, and the other end of the spring is fixedly connected to one side of the damping sleeve. The springs can help the damping sleeve to reset its relative position.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This utility model features a bidirectional vibration-damping and waterproof hammer structure, which can effectively absorb and dissipate vibration energy in both horizontal and vertical directions. This reduces the vibration amplitude of the pipeline, prevents fatigue damage and loosening of connections caused by long-term vibration, increases the service life of the pipeline system, reduces noise generated by pipeline vibration, improves the comfort of the working and living environment, and ensures the stability and safety of the entire system.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, please refer to Figures 1 to 5 This utility model provides a technical solution: a heating and ventilation pipe installation bracket for heating and ventilation engineering, including a main housing 1. The main housing 1 is characterized by having a positive and negative threaded rod 2 rotatably connected internally, with one end extending outwards. The outer surface of the positive and negative threaded rod 2 is threadedly connected to two internal threaded blocks 3. A first shaft block 4 is fixedly connected to the bottom of each internal threaded block 3. A first connecting rod 5 is rotatably connected internally to the first shaft block 4. A second shaft block 6 is rotatably connected to the end of the first connecting rod 5 away from the first shaft block 4. A clamping plate 7 is fixedly connected to one side of the second shaft block 6. A rotating rod 8 is fixedly embedded at one end of the clamping plate 7. The two ends of the two rotating rods 8 are rotatably connected to the inside of the main housing 1. A limiting component is provided on the outer surface of the internal threaded blocks 3. The limiting component also includes a limiting sleeve 11. One side of the limiting sleeve 11 is fixedly connected to the outer surface of the internal threaded blocks 3. The inner surfaces of the two limiting sleeves 11 are movably embedded with… A limiting rod 12 is fixedly connected to the inner surface of the main housing 1 at both ends. A rotating block 13 is fixedly connected to one end of the forward and reverse lead screw 2. A rocker arm 14 is movably embedded inside the rotating block 13. A fixing member 15 is fixedly connected to the top of the main housing 1. A damping rod 16 is fixedly connected inside the fixing member 15. Two damping sleeves 17 are movably sleeved on the outer surface of the damping rod 16. A third shaft block 18 is fixedly connected to the top of the damping sleeve 17. A second connecting rod 19 is rotatably connected inside the third shaft block 18. A fourth shaft block 20 is rotatably connected to the end of the second connecting rod 19 away from the third shaft block 18. A mounting plate 21 is fixedly connected to the top of the two fourth shaft blocks 20. Two springs 22 are movably sleeved on the outer surface of the damping rod 16. One end of the spring 22 is fixedly connected to the inner side of the fixing member 15, and the other end of the spring 22 is fixedly connected to one side of the damping sleeve 17.

[0025] In this embodiment, the mounting plate 21 is first installed at the target position, and then the pipe is pre-aligned on the inner side of the two clamping plates 7. Then, the rocker arm 14 and the rotating block 13 drive the positive and negative screw 2 to rotate inside the main housing 1. The rotating screw drives the internal thread block 3. The limiting plate 9 at the top of the internal thread block 3 can only move along the slotting direction of the limiting groove 10. Therefore, the rotating screw drives the internal thread blocks 3 to move closer to each other along the slotting direction of the limiting groove 10. When the internal thread blocks 3 move, they drive one end of the first connecting rod 5 through the first shaft block 4. The other end of the first connecting rod 5 drives the clamping plate 7 through the second shaft block 6, so that the clamping plate 7 swings about the rotating rod 8 at the top as the axis and clamps and fixes the internal pipe. When the pipeline vibrates due to the sudden closure or opening of the water flow, its horizontal vibration will cause the connecting rod damping sleeve 17 to move directly in the same direction on the outer surface of the damping rod 16 on the fixing member 15. When the damping sleeve 17 moves on the outer surface of the damping rod 16, it will consume the vibration energy through damping. The spring 22 can help the damping sleeve 17 to reset its relative position. When vertical vibration occurs, the fourth shaft block 20 at the bottom of the mounting plate 21 will drive one end of the second connecting rod 19. The other end of the second connecting rod 19 will drive the damping sleeve 17 to move away from or closer to each other on the outer surface of the damping rod 16 through the third shaft block 18. When moving, it will consume the vibration energy through damping. The spring 22 can help the damping sleeve 17 to reset its relative position.

[0026] Example 2, please refer to Figures 1 to 5 The limiting assembly also includes a limiting sleeve 11. One side of the limiting sleeve 11 is fixedly connected to the outer surface of the internal thread block 3. The inner surfaces of the two limiting sleeves 11 are movably embedded with limiting rods 12. The two ends of the limiting rods 12 are fixedly connected to the inner surface of the main housing 1.

[0027] In this embodiment, when the internal threaded block 3 moves, the limiting sleeve 11 can only move in the axial direction of the limiting rod 12, causing the two internal threaded blocks 3 to move away from or closer to each other along the axial direction of the limiting rod 12.

[0028] Working principle: First, install the mounting plate 21 at the target position, then pre-align the pipe with the inner side of the two clamping plates 7. Then, drive the positive and negative screws 2 to rotate inside the main housing 1 through the rocker arm 14 and the rotating block 13. The rotating screw will drive the internal thread block 3. The limiting plate 9 at the top of the internal thread block 3 can only move along the slotting direction of the limiting groove 10. Therefore, the rotating screw will drive the internal thread blocks 3 to move closer to each other along the slotting direction of the limiting groove 10. When the internal thread block 3 moves, it will drive one end of the first connecting rod 5 through the first shaft block 4. The other end of the first connecting rod 5 will drive the clamping plate 7 through the second shaft block 6, so that the clamping plate 7 swings around the rotating rod 8 at the top as the axis, and clamps and fixes the internal pipe. When the pipe vibrates due to the sudden closing or opening of the water flow, its horizontal vibration will cause the connecting rod to move closer to the internal thread block 10. The damping sleeve 17 moves directly in the same direction on the outer surface of the damping rod 16 on the fixing member 15. When the damping sleeve 17 moves on the outer surface of the damping rod 16, it will consume vibration energy through damping. The spring 22 can help the damping sleeve 17 reset its relative position. When vertical vibration occurs, the fourth shaft block 20 at the bottom of the mounting plate 21 will drive one end of the second connecting rod 19. The other end of the second connecting rod 19 will drive the damping sleeve 17 to move away from or closer to each other on the outer surface of the damping rod 16 through the third shaft block 18. When moving, it will consume vibration energy through damping. The spring 22 can help the damping sleeve 17 reset its relative position. When the internal thread block 3 moves, it can only move in the axial direction of the limiting rod 12 by using the limiting sleeve 11. This will drive the two internal thread blocks 3 to move away from or closer to each other along the axial direction of the limiting rod 12.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
