Description

Technical Field

[0001] The utility model relates to the technical field of installation hangers for HVAC pipelines, and specifically to an anti-seismic structure for hoisting building HVAC pipelines. Background Technique

[0002] Building HVAC pipelines are key components used for heating, ventilation, and air conditioning systems inside buildings. They are crucial for the comfort and air quality of buildings. The HVAC pipelines need to be installed on the building wall tops, and the pipeline system requires sufficient fixing points and support structures to avoid violent movement or damage during earthquakes. Therefore, an anti-seismic structure for hoisting building HVAC pipelines is used to fix and support the HVAC pipelines, and it has a certain anti-seismic performance.

[0003] However, the existing anti-seismic structures for hoisting building HVAC pipelines have the following disadvantages. When installing HVAC pipelines, an installation bracket is needed to install the HVAC pipelines on the wall tops. When the HVAC pipelines are subjected to external forces, they will shake. Therefore, some shock-absorbing buffer pads are installed between the installation bracket and the HVAC pipelines. However, the buffer structure is relatively simple, which reduces the stability of the hoisting structure of the HVAC pipelines. Therefore, the existing anti-seismic structures for hoisting building HVAC pipelines need to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-seismic structure for hoisting building HVAC pipelines to solve the problems in the above background technique that the buffer structure of the existing anti-seismic structures for hoisting building HVAC pipelines on the market is relatively simple and the anti-seismic performance is not high.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An anti-seismic structure for hoisting building HVAC pipelines, including a side frame and a clamping plate. The bottom end of the side frame is connected with a bottom frame. The clamping plate is arranged on one side of the side frame. A chute is opened inside the bottom frame, and a connecting plate is slidably connected to the inner side of the chute. A first buffer mechanism and a first damper are connected between the clamping plate and the bottom frame. A second buffer spring is sleeved outside the first damper. A buffer groove is opened on the inner side of the side frame close to the clamping plate, and a second buffer mechanism is connected to one side of the buffer groove. The second buffer mechanism is connected to the clamping plate.

[0006] Preferably, the first buffer mechanism includes a first connecting rod, a second connecting rod, and a first buffer spring. The bottom end of the clamping plate close to the bottom frame is connected with the first connecting rod through a rotating seat.

[0007] Preferably, the second connecting rod is connected to the upper part of the bottom frame through a rotating seat, and the first connecting rod and the second connecting rod are connected by a movable shaft.

[0008] Preferably, the second buffer mechanism includes a third buffer spring, a second damper, a fourth buffer spring, a slide bar, and a slider. The slide bar is installed inside the buffer groove.

[0009] Preferably, the outer side of the slide bar is slidably sleeved with a fourth buffer spring and a slider. A second damper is connected between the slider and the clamping plate through a movable shaft, and a third buffer spring is sleeved outside the second damper.

[0010] Preferably, positioning grooves are formed on both sides of the connecting plate, and a positioning mechanism is connected inside the positioning grooves. The positioning mechanism is connected to the chassis.

[0011] Preferably, the positioning mechanism includes a positioning rod, a through groove, and a fastening ring. The positioning rod penetrates through the inside of the positioning groove.

[0012] Preferably, through grooves are formed on both sides of the chassis close to the positioning rod, and fastening rings are provided at both ends of the positioning rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The first buffer mechanism and the second buffer mechanism are provided. When the HVAC pipeline shakes up and down, the first connecting rod and the first damper are squeezed by the HVAC pipeline and the clamping plate. Subsequently, the first connecting rod squeezes the second connecting rod, causing the first connecting rod and the second connecting rod to rotate around the movable shaft and the rotating seat. The first connecting rod, the second connecting rod, and the first buffer spring buffer the clamping plate and the HVAC pipeline. At the same time, the up and down shaking of the clamping plate and the HVAC pipeline will pull the second damper downward. The second damper drives the slider to slide up and down on the outer side of the slide bar and squeeze the third buffer spring, buffering the up and down shaking of the clamping plate and the HVAC pipeline again. The second damper and the fourth buffer spring buffer the left and right shaking of the HVAC pipeline. Multiple buffer structures can effectively disperse the vibration force and improve the seismic resistance of the building HVAC pipeline anti-seismic hoisting structure.

[0015] 2. The positioning mechanism is provided. Pull the chassis to both sides, make the two ends of the connecting plate slide in the chute, make the clamping plates move away from each other. Then place the HVAC pipeline from top to bottom inside the clamping plates. Then push the chassis again to make the connecting plate slide in the chute again, making the clamping plates move closer to each other. Then install bolts on both sides of the clamping plates to make the clamping plates sleeved on both sides of the HVAC pipeline. Then insert the positioning rod into the positioning groove from the through groove. Finally, thread the fastening ring onto both ends of the positioning rod to limit the position of the connecting plate, which can quickly install the side frame and the chassis on the outside of the HVAC pipeline and improve the installation convenience of the building HVAC pipeline hoisting anti-seismic structure.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: an anti-seismic structure for hoisting building HVAC pipelines, including a side frame 1 and a splint 3. The bottom end of the side frame 1 is connected to a chassis 2. The splint 3 is arranged on one side of the side frame 1. A chute 10 is opened inside the chassis 2, and a connecting plate 4 is slidably connected to the inner side of the chute 10.

[0024] Please refer to Figures 1 - 3, a first buffer mechanism 5 and a first damper 6 are connected between the clamping plate 3 and the chassis 2. A second buffer spring 7 is sleeved outside the first damper 6. A buffer groove 8 is provided inside the side frame 1 close to the clamping plate 3. A second buffer mechanism 9 is connected to one side of the buffer groove 8. The second buffer mechanism 9 is connected to the clamping plate 3. The first buffer mechanism 5 includes a first connecting rod 501, a second connecting rod 502 and a first buffer spring 503. The bottom end of the clamping plate 3 close to the chassis 2 is connected to the first connecting rod 501 through a rotating seat. The second connecting rod 502 is connected above the chassis 2 through a rotating seat. The first connecting rod 501 and the second connecting rod 502 are connected by a movable shaft. The second buffer mechanism 9 includes a third buffer spring 901, a second damper 902, a fourth buffer spring 903, a sliding rod 904 and a slider 905. The sliding rod 904 is installed inside the buffer groove 8. The fourth buffer spring 903 and the slider 905 are slidably sleeved outside the sliding rod 904. A second damper 902 is connected between the slider 905 and the clamping plate 3 through a movable shaft. A third buffer spring 901 is sleeved outside the second damper 902.

[0025] During specific implementation, when installing the HVAC pipeline, an installation bracket is required to install the HVAC pipeline on the wall top. When the HVAC pipeline is affected by external forces, it will shake. Therefore, some shock-absorbing cushions are installed between the installation bracket and the HVAC pipeline. However, the buffer structure is relatively simple, which reduces the stability of the HVAC pipeline hoisting structure. When the HVAC pipeline shakes up and down, the first connecting rod 501 and the first damper 6 are squeezed by the HVAC pipeline and the clamping plate 3. Subsequently, the first connecting rod 501 squeezes the second connecting rod 502, causing the first connecting rod 501 and the second connecting rod 502 to rotate around the movable shaft and the rotating seat. The first connecting rod 501, the second connecting rod 502 and the first buffer spring 503 buffer the clamping plate 3 and the HVAC pipeline. At the same time, the up and down shaking of the clamping plate 3 and the HVAC pipeline will pull the second damper 902 downward. The second damper 902 drives the slider 905 to slide up and down outside the sliding rod 904 and squeeze the third buffer spring 901, buffering the up and down shaking of the clamping plate 3 and the HVAC pipeline again. The second damper 902 and the fourth buffer spring 903 buffer the left and right shaking of the HVAC pipeline. And the amplitude of the left and right shaking of the HVAC pipeline is not high. Multiple buffer structures can effectively disperse the vibration force and improve the seismic resistance of the building HVAC pipeline anti-seismic hoisting structure.

[0026] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, positioning grooves 11 are formed on both sides of the connecting plate 4, a positioning mechanism 12 is connected to the inner side of the positioning groove 11, the positioning mechanism 12 is connected to the chassis 2, the positioning mechanism 12 includes a positioning rod 1201, a through groove 1202 and a fastening ring 1203, the positioning rod 1201 penetrates through the inner side of the positioning groove 11, through grooves 1202 are formed on both sides of the chassis 2 close to the positioning rod 1201, fastening rings 1203 are arranged at both ends of the positioning rod 1201, the fastening rings 1203 are threadedly sleeved between the two ends of the positioning rod 1201, and the cross-sectional shapes of the positioning rod 1201, the positioning groove 11 and the through groove 1202 are all polygons.

[0027] During specific implementation, when installing the building HVAC pipeline hoisting seismic structure on the outside of the HVAC pipeline, since the brackets are fixedly connected, it is inconvenient to disassemble the brackets according to the installation requirements, resulting in low installation efficiency. The chassis 2 can be pulled to both sides, so that the two ends of the connecting plate 4 slide in the sliding groove 10, making the clamping plates 3 move away from each other. Then, the HVAC pipeline is placed inside the clamping plates 3 from top to bottom. Then, the chassis 2 is pushed to make the connecting plate 4 slide in the sliding groove 10 again, so that the clamping plates 3 move closer to each other. Then, bolts are installed on both sides of the clamping plates 3 to make the clamping plates 3 sleeved on both sides of the HVAC pipeline. Then, the positioning rod 1201 is inserted into the positioning groove 11 from the through groove 1202. Finally, the fastening rings 1203 are threadedly sleeved on both ends of the positioning rod 1201 to limit the position of the connecting plate 4, and the side frame 1 and the chassis 2 can be quickly installed on the outside of the HVAC pipeline, improving the installation convenience of the building HVAC pipeline hoisting seismic structure.

[0028] Working principle: When using the building HVAC pipeline hoisting seismic structure, first, the side frame 1 and the chassis 2 are installed on the outside of the HVAC pipeline through the positioning mechanism 12 and the clamping plates 3, and then the side frame 1 is installed on the wall top through bolts. When shaking occurs under the action of external forces, the up, down, left and right shaking of the HVAC pipeline can be buffered through the first buffer mechanism 5 and the second buffer mechanism 9, improving the stability and seismic resistance of the building HVAC pipeline hoisting seismic structure. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
