Description

Technical Field

[0001] This utility model relates to a hoisting device, specifically a hoisting device for a three-way pipe. Background Technology

[0002] In central air conditioning systems, the three-way duct is a key component for achieving airflow distribution, and its performance directly affects the operating efficiency and effectiveness of the entire air conditioning system.

[0003] Currently, existing central air conditioning T-junction ducts are typically installed by fixing them to brackets or using hangers. Specifically, the T-junction bracket is first installed, then screwed to the wall. The duct is then connected to the bracket, using fasteners or sealing materials if necessary. Alternatively, when using hangers to suspend the indoor unit, clamps are installed at appropriate locations to secure the T-junction duct, ensuring stability and accurate positioning.

[0004] As mentioned above, the existing hoisting method is relatively poorly adaptable to different structures and spaces. It is limited by factors such as wall structure and space height, and cannot adjust the height of the T-junction pipe at any time. Utility Model Content

[0005] The main purpose of this utility model is to provide a hoisting device for a three-way pipe, which makes the hoisting device better adaptable to different floor heights and has stronger adaptability.

[0006] To achieve the above objectives, this utility model provides a hoisting device for a tee pipe. The hoisting device includes multiple expansion bolts, a hanging plate, and a hanger. The expansion bolts are evenly distributed on both sides of the hanging plate, and the expansion bolts on both sides of the hanging plate are spaced apart. The bottom of the expansion bolts is provided with compression plates. These compression plates together compress the hanging plate to the top of the floor. The compression plates can rotate relative to the screw of the expansion bolt. The hanger is detachably installed below the hanging plate.

[0007] Preferably, the hanger includes two hangers, a U-shaped frame, and a cover plate. The two ends of the hangers are respectively provided with external threads. The top of the hanger is screwed to the hanger plate. The cover plate is fastened to the open end of the U-shaped frame. The hangers fix the cover plate and the U-shaped frame together, so that the cover plate and the U-shaped frame form a square frame, which is fitted onto the outside of the tee pipe.

[0008] Preferably, the expansion bolt includes an expansion sleeve, a screw, a nut, a compression washer, and a compression support. One end of the screw is fixedly connected to the nut, and the other end of the screw is screwed into the expansion sleeve. The compression support is located above the compression washer and between the compression support and the nut.

[0009] In a further preferred embodiment, the extrusion support plate is fan-shaped, and a through hole is provided near the large arc end of the extrusion support plate, through which the extrusion support plate is rotatably connected to the screw.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. Distributed expansion bolts + spaced arrangement design

[0012] The hoisting device supports the lifting plate with expansion bolts evenly distributed and spaced on both sides. Compared with traditional single-point suspension or single-sided fixation, the force is more evenly distributed, which improves the ability to withstand the vibration load of the pipeline during operation and avoids the risk of loosening or falling off due to long-term use.

[0013] 2. Highly adaptable:

[0014] By adjusting the length of the hanger, it can better adapt to different floor heights and the size and weight of T-joint pipes, making it highly adaptable. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figure 1As shown, this embodiment provides a T-junction duct 100 for central air conditioning. Hanging brackets are provided at the three openings of the T-junction duct 100, and the T-junction duct 100 is installed on the roof via these three hanging brackets. In this embodiment, the interior of the T-junction duct 100 has a herringbone-shaped channel 110, while the exterior of the T-junction duct 100 is T-shaped. The herringbone-shaped design of the interior, compared to the traditional T-shaped structure, results in a more uniform airflow field at the branching point, reducing eddy current losses. The T-shaped exterior is designed to maintain the overall aesthetic appeal. A flow divider 200 is provided at the branching point of the T-junction duct 100, which controls the air intake volume inside the branch duct 142 that needs to be controlled. For example, to control the flow rate in one of the branch pipes 142, the diversion gate 200 can be turned towards that branch pipe 142, thereby reducing the air inlet of that branch pipe 142 and controlling the airflow within it. If it is necessary to completely close the branch pipe 142, the diversion gate 200 can be turned to its maximum angle, so that the end of the diversion gate 200 seals against the wall of the branch pipe 142, thus cutting off the airflow to that branch pipe 142. In this way, the air intake volume in both branch pipes can be adjusted by using the diversion gate 200.

[0040] Additionally, it should be noted that the diversion gate 200 can only adjust the airflow of the branch pipe 142. This is to flexibly achieve synchronous control of the air intake volume of the two branch pipes 142 (uniform diversion, proportional adjustment, or unidirectional closure) to meet the diverse airflow distribution needs of the central air conditioning system. For example, the diversion gate 200 can adjust the air intake volume of the two branch pipes 142 to 40:60, or completely close one branch pipe 142. However, if it is desired to simultaneously control the air output volume at the ends of the two connecting pipes 10 connected to the branch pipes 142, it is also necessary to use the air-closing valves on each connecting pipe 10. The air output volume at the ends of the connecting pipes 10 is controlled by the opening and closing degree of the air-closing valves.

[0041] In this embodiment, as Figure 2 and Figure 3 As shown, both the inlet and outlet ends of the tee pipe 100 are provided with extension plates 120, and the extension plates 120 are provided with annular grooves 121. The annular grooves 121 surround the inlet and outlet ends of the tee pipe 100, and a sealing ring 150 is provided inside the annular grooves 121. At the same time, both the inlet and outlet ends of the tee pipe 100 are inverted flared mouths 130. In this way, the design of the sealing ring 150 and the inverted flared mouth 130 complement each other, which can effectively avoid the misalignment range during pipe connection and avoid sealing failure caused by installation deviation.

[0042] Specifically, in this embodiment, such as Figure 4 and Figure 5As shown, the diversion gate 200 includes a diversion plate 220, a drive motor 230, and a rotating plate. The diversion plate 220 is fixedly connected to the inner wall of the main pipe 141 of the tee pipe 100, and the top of the diversion plate 220 is rotatably connected to the rotating plate. The drive motor 230 is fixed to the top of the tee pipe 100 by a motor bracket 210. The drive motor 230 can drive the rotating plate to rotate, and the end of the rotating plate away from the top of the diversion plate 220 can seal against the inner wall of the tee pipe 100. In this embodiment, the top of the diversion plate 220 is arranged in a slightly curved shape, and one end of the rotating plate is rotatably sealed to the top of the diversion plate 220. Preferably, rubber pads can be provided at both ends of the top of the diversion plate 220 to prevent airflow from flowing in the gap between the rotating plate and the top of the diversion plate 220. Preferably, in this embodiment, the drive motor 230 is a stepper motor.

[0043] In this embodiment, the rotating plate includes a rotating shaft 240 and a movable plate 260. The rotating shaft 240 is rotatably and sealingly connected to the top of the air distribution plate 220. One end of the movable plate 260 is fixedly connected to the rotating shaft 240, and the other end of the movable plate 260 can seal against the inner wall of the tee pipe 100. Preferably, the other end of the movable plate 260 can be set in an arc shape to achieve better sealing. Alternatively, a rubber gasket can be provided at the other end of the movable plate 260 to achieve a sealing effect.

[0044] Specifically, in this embodiment, the top end of the rotating shaft 240 extends through the tee pipe 100 and is fixedly connected to the driven gear 232, while the end of the rotating shaft 240 of the drive motor 230 is fixedly connected to the driving gear 231. The driving gear 231 meshes with the driven gear 232, thereby enabling the drive motor 230 to drive the rotating shaft 240 to rotate. Alternatively, in other embodiments, the number of teeth on the driving gear 231 is less than the number of teeth on the driven gear 232. In this way, the driving gear 231 and the driven gear 232 cooperate to form a reduction gear (the transmission ratio can be set according to actual needs), thereby allowing for better adjustment of the rotation angle of the movable plate 260.

[0045] In this embodiment, as Figure 6 and Figure 7 As shown, the hoisting device 300 includes multiple expansion bolts 310, a hanging plate 350, and a hanger. The expansion bolts 310 are evenly distributed on both sides of the hanging plate 350, with the expansion bolts 310 on both sides of the hanging plate 350 spaced apart. The expansion bolts 310 can support the hanging plate 350, and the hanger is detachably installed below the hanging plate 350. Compared with traditional single-point suspension or unilateral fixing, this installation method results in more uniform force distribution, effectively improving the ability to withstand vibration loads during pipeline operation and avoiding the risk of bolt loosening or falling off due to long-term use.

[0046] Preferably, in this embodiment, the expansion bolt 310 includes an expansion sleeve 311, a screw 312, a nut, a compression washer 314, and a compression support 313. One end of the screw 312 is fixedly connected to the nut. The compression support 313 is located above the compression washer 314 and is used to support the suspended platform 350. The suspended platform 350 is tightly attached to the top of the floor by the compression support 313. Preferably, the compression support 313 is fan-shaped, and a through hole is provided near the large arc end of the compression support 313. The compression support is rotatably connected to the screw through the through hole. After installation, the compression support 313 is tapped to press the suspended platform 350 against the top of the floor.

[0047] Specifically, in this embodiment, the hanger includes two hanger rods 340, a U-shaped frame 320, and a cover plate 330. The two ends of the hanger rods 340 are respectively provided with external threads. The top end of the hanger rods 340 is screwed to the hanger plate 350. The cover plate 330 is fastened to the opening of the U-shaped frame 320. The hanger rods 340 fix the cover plate 330 and the U-shaped frame 320 together. The cover plate 330 and the U-shaped frame 320 are combined to form a square frame so as to be fitted onto the outside of the tee pipe 100.

[0048] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
