Description

Technical Field

[0001] This invention relates to the field of air conditioning unit installation technology, specifically to an air conditioning unit suspension device and method. Background Technology

[0002] In the installation of air conditioning units, the suspension system is a key load-bearing structure that ensures stable operation of the equipment and building safety. It typically consists of high-strength fully threaded rods, rubber pads, and upper and lower fastening nuts, achieving aerial fixation of the air conditioning unit by rigidly or elastically connecting it to the floor slab or beam bottom.

[0003] When air conditioning units are suspended using a suspension device, the uneven weight distribution within the unit means that the fan section is typically significantly heavier than the cooling coil section. This uneven weight distribution can easily cause the air conditioning unit to tilt or shift, and may even lead to it falling, posing a significant safety hazard.

[0004] Therefore, we propose an air conditioning unit suspension device and method to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems mentioned above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An air conditioning unit suspension device includes a support plate, a suspension plate, and several fixing ribs fixed between the support plate and the suspension plate. The top of the support plate is used to support the air conditioning unit. The top of the suspension plate is connected to the same suspension plate by several traction ropes. A correction seat is installed at the bottom of the suspension plate, and a pull rope is installed on the correction seat. A correction component is installed at the top of the suspension plate. When an air conditioning unit with uneven weight distribution is placed on the support plate and suspended, the lower part of the pull rope is hung on the unbalanced end of the correction component to reduce the degree of uneven load on the support plate.

[0007] Furthermore: a suspension frame is fixed to the top of the suspension plate, a first hanging piece is fixed to the corner of the suspension frame, and one end of the traction rope is fixed to the first hanging piece.

[0008] Furthermore: there are four correction components, and the four correction components are fixed at the edge of the suspension frame respectively; the top of the correction component is provided with several first correction grooves at equal intervals, and the cross-section of the first correction groove is set with a "convex" structure; the two ends of the correction component are respectively provided with second correction grooves, and the cross-section of the second correction groove is set with a "U" shape.

[0009] Furthermore, the top of the alignment seat is integrally formed with a mounting plate, which is connected to the bottom of the suspension plate by a number of fixing bolts to fix the suspension plate and the alignment seat.

[0010] Furthermore: the bottom of the suspension plate is provided with a protective cylinder, and the correction seat is located inside the protective cylinder. When the correction seat falls downward, the protective cylinder is used to protect the correction seat. Two through holes are symmetrically opened about the axis on the circumference of the protective cylinder, and the pull rope passes through the two through holes.

[0011] Furthermore: a rotating support is fixed at the bottom of the suspension plate, and the correction seat is coaxially arranged with the rotating support. The upper part of the protective cylinder is rotatably mounted on the rotating support. When the protective cylinder rotates relative to the correction seat, on the one hand, a part of the pull rope is wound onto the correction seat to adjust the length of the pull rope so that the pull rope is hung at different positions on the correction component; on the other hand, the protective cylinder drives the pull rope to rotate and adjust so that the pull rope is hung on two different correction components.

[0012] Furthermore, a receiving chamber is formed between the correction seat and the protective cylinder, and the receiving chamber is used to restrict the winding pull rope to prevent the wound pull rope from falling off the correction seat.

[0013] Furthermore: a ratchet is fixed on the upper circumferential surface of the protective cylinder, and a rotating shaft is fixed on the bottom of the suspension plate. The rotating shaft is equipped with ratchet teeth that cooperate with the ratchet. The ratchet and ratchet teeth are used to limit the movement of the protective cylinder so that the protective cylinder can only rotate in one direction.

[0014] Furthermore: a stepped hole is provided in the center of the ratchet, and a torsion spring is installed inside the stepped hole; a blocking shaft is fixed on the stepped hole and the rotating shaft respectively, and the two blocking shafts abut against the two ends of the torsion spring respectively.

[0015] A method for using an air conditioning unit suspension device includes the following steps: S1: Place the air conditioning unit on the support plate in advance; The air conditioning unit is placed in the center of the support plate and between several fixing ribs to facilitate subsequent suspension work; S2: Adjust the length and orientation of the traction rope according to the gravity distribution of the air conditioning unit; The protective cylinder rotates relative to the correction seat, causing the part of the traction rope near the protective cylinder to be wound onto the correction seat, thereby adjusting the length of the traction rope. In addition, since the correction seat is rotating, the position of the connection between the traction rope and the protective cylinder will also change direction, thereby adjusting the connection position between the traction rope and the correction seat so that the force is even when the traction rope pulls on the two corresponding correction components.

[0016] S3: The adjusted traction rope is hung on the two corresponding correction components; Pull the traction rope into a triangular structure so that the two ends of the lower part of the traction rope are respectively attached to the two corresponding correction components.

[0017] S4: The suspension device supporting the air conditioning unit is lifted and transported using hoisting equipment; When the hoisting device is suspended at a high altitude, the traction rope pulls on the unbalanced end of the load-bearing plate to reduce the uneven load-bearing capacity of the load-bearing plate. The beneficial effects of this invention are: 1. This invention features a correction seat installed at the bottom of the suspension plate and a correction component installed at the top of the suspension plate. A pull rope on the correction seat can be attached to the corresponding correction component. Through the coordinated action of the correction seat, pull rope, and correction component, a pulling force can be applied to the support plate on which the air conditioning unit is placed, thereby effectively alleviating the problem of uneven load distribution on the support plate and reducing the risk of tilting or falling during suspension.

[0018] 2. This invention features a protective cylinder installed at the center of the suspension plate, with the alignment correction component housed inside the protective cylinder. This design serves two purposes: firstly, the protective cylinder provides effective support for the alignment correction component, reducing the load on the connection between the component and the suspension plate and preventing loosening; secondly, even if the alignment correction component becomes loose, the protective cylinder still provides temporary support to the alignment correction base, ensuring uninterrupted normal operation of the device and significantly improving overall stability.

[0019] 3. In this invention, the protective cylinder and the suspension plate are connected by a rotating mechanism. When the protective cylinder rotates relative to the correction seat, it can achieve the following three functions: First, a portion of the pull rope can be wound into the storage chamber, thereby flexibly adjusting the length of the pull rope according to user needs, allowing the pull rope to be hooked into different first or second correction slots on the correction component; Second, the orientation of the connection between the pull rope and the protective cylinder can be changed, which helps to make the force more even when the correction component is pulled in different directions; Third, the receiving chamber formed by the protective cylinder and the correction seat can limit the wound pull rope, preventing the wound pull rope from detaching from the correction seat.

[0020] 4. This invention features a ratchet mounted above the protective cylinder and a ratchet tooth mounted below the suspension plate. The ratchet tooth and ratchet wheel work together to achieve a one-way locking function for the protective cylinder. This design can lock the wound-up rope, preventing one end of the rope from continuously falling downwards due to its own weight, thus avoiding the phenomenon of the wound-up rope releasing from the guide seat.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0024] Example 1 An air conditioning unit suspension device includes a support plate 1 and a suspension plate 2, with the support plate 1 located below the suspension plate 2. Several fixing ribs 3 are provided between the support plate 1 and the suspension plate 2, which serve to fix the support plate 1 and the suspension plate 2.

[0025] In detail: The fixing rib 3 includes a hanger 301, with both ends of the hanger 301 penetrating the bearing plate 1 and the suspension plate 2 respectively. Two sets of hexagonal nuts 302 are threaded onto the upper and lower parts of the hanger 301. The two lower hexagonal nuts 302 are respectively fitted to the top and bottom surfaces of the bearing plate 1; the two upper hexagonal nuts 302 are respectively fitted to the top surface of the suspension plate 2 and the ground. This installation method is advantageous because it is simple to assemble, allowing for quick assembly when the suspension device is transported to the construction site, facilitating operation and providing convenience for workers. Furthermore, it should be noted that washers 303 are provided at the connection points between the bearing plate 1 and the hexagonal nuts 302, and at the connection points between the suspension plate 2 and the hexagonal nuts 302. The washers 303 enhance the firmness, prevent loosening, and provide strong stability.

[0026] A suspension frame 201 is fixed to the top of the suspension plate 2. A first hanger 202 is fixed at the corner of the suspension frame 201. A traction rope 4 is fixed to several first hangers 202 respectively. Several second hangers 501 are fixed at equal intervals on the circumference of the suspension plate 5. The first hangers 202 and the second hangers 501 are respectively set in a U-shape. The top ends of several traction ropes 4 are respectively fixed to the second hangers 501. A hook 17 is fixed at the center of the top of the suspension plate 5. Through the setting of the hook 17, the hoisting equipment (crane) can hoist the suspension device.

[0027] Example 2 Although the above embodiments can suspend the air conditioning unit, the weight of air conditioning units on the market is usually unevenly distributed. According to multiple surveys, about 70% of the weight is distributed in the fan section of the air conditioning unit, and about 30% of the weight is distributed in the surface cooling end. If the suspension device of Embodiment 1 is used for suspension, the load-bearing capacity is prone to uneven distribution. During the suspension process, tilting or displacement may easily occur, and there is even a risk of falling. Therefore, in order to overcome the above-mentioned technical problems, improvements are made based on Embodiment 1. A correction seat 6 is fixed to the bottom of the suspension plate 5, and the correction seat 6 is located at the center of the suspension plate 5, so that the force on the suspension plate 5 is more even. A pull rope 7 is installed on the correction seat 6. Under normal circumstances, the correction seat 6 has a through hole 601, and the pull rope 7 is set through the through hole 601; moreover, the two ends of the pull rope 7 are fixedly set to form a closed loop to prevent the pull rope 7 from coming off the inside of the through hole 601.

[0028] It should be noted that the top of the correction seat 6 is integrally formed with a mounting plate 9, and the suspension plate 5 has several threaded holes 502. Several fixing bolts 10 pass through the mounting plate 9 and are threaded into the inside of the threaded holes 502, thereby fixing the correction seat 502.

[0029] A correction component 8 is installed on the upper part of the suspension plate 2, and preferably there are four correction components 8. The four correction components 8 are fixed at the edge of the suspension frame 201 respectively. When an air conditioning unit with uneven weight distribution is placed on the bearing plate 1 and suspended, the lower part of the pull rope 7 can be hung on the unbalanced end of the correction component 8 to reduce the degree of uneven bearing force on the bearing plate 1. This effectively avoids tilting or displacement and improves the practicality of the device.

[0030] It should be noted that the four correction components 8 are identical in size and shape. For ease of description, this embodiment only describes one correction component 8. Several first correction grooves 801 are equidistantly spaced on the correction component 8, and the cross-section of the first correction grooves 801 is a convex shape. The advantage of this design is that when the pull rope 7 pulls two corresponding correction components 8, it can be hung on the first correction grooves 801 of the corresponding two correction components 8. When the pull rope 7 pulls two adjacent correction components 8, it can also be hung on the first correction grooves 801 of the two adjacent correction seats 8, thus allowing for flexible adjustment according to user needs and possessing strong practicality. Second correction grooves 802 are respectively provided at both ends of the correction component 8, and the cross-section of the second correction grooves 802 is a U-shaped structure. When the pull rope 7 pulls the other two corresponding correction components 8, the pull rope 7 can also be hung inside the second correction grooves 802.

[0031] Example 3 Although the above embodiment 2 can pull the bearing plate 2 by cooperating with the correction seat 6, the pull rope 7 and the correction component 8, thus alleviating the problem of uneven bearing force of the bearing plate 1, the correction seat 6 is prone to loosening under long-term pulling because it is only connected to the suspension plate 2 by the fixing bolt 10. This can easily lead to failure of the pulling force on the suspension plate 2. Therefore, in order to solve the above-mentioned technical problems, further improvements are made based on embodiment 2. A protective cylinder 11 is installed at the bottom of the suspension plate 2, and the correction seat 6 is located inside the protective cylinder 11. Specifically, the protective cylinder 11 has two through holes 1101, which are symmetrically arranged about the axis of the protective cylinder 11. The pull rope 7 passes through the two through holes 1101 to ensure the normal use of the device. In addition, a rotating hole 1102 is provided at the center of the bottom of the protective cylinder 11, and a rotating shaft 602 is fixed at the bottom of the correction seat 6. The rotating shaft 602 is located inside the rotating hole 1102. The protective cylinder 11 provides a certain load-bearing capacity for the correction seat 6, which can effectively prevent the connection between the correction seat 6 and the suspension plate 5 from being too tensile and loose. In addition, even if the correction seat 6 becomes loose, the protective cylinder 11 can still support the correction seat 6 and will not affect the normal use of the correction seat 6.

[0032] Example 4 In Embodiments 2 and 3 above, when the pull rope 7 pulls the suspension plate 2, the length of the pull rope 7 remains constant. Therefore, it is impossible to flexibly adjust the length and orientation of the pull rope 7, resulting in poor adaptability. Therefore, in order to solve the above problems, an improvement is made to Embodiment 3.

[0033] A rotating support 12 is fixed at the center of the bottom of the suspension plate 5, and the correction seat 6 is coaxially arranged with the rotating support 12. The upper part of the protective cylinder 11 is rotatably mounted on the rotating support 12. In detail, a limiting rotating ring 1201 is fixed on the outer circumferential surface of the rotating support 12, and a rotating groove 1303 is opened on the inner circumferential surface of the protective cylinder 11. The rotating ring 1201 is rotatably mounted inside the rotating groove 1303. Through the cooperation of the rotating ring 1201 and the rotating groove 1303, the protective cylinder 11 can not only rotate on the rotating support 12, but also be limited to prevent the protective cylinder 11 from falling downwards during use.

[0034] When the protective cylinder 11 rotates relative to the correction seat 6, on the one hand, a portion of the pull rope 7 is wound onto the correction seat 6, thereby adjusting the length of the pull rope 7; on the other hand, the position of the connection between the pull rope 7 and the protective cylinder 11 also changes direction, allowing the pull rope 7 to be hung on different correction components 8, thus achieving the function of adjusting the direction of the pull rope 7. It has strong practicality.

[0035] Of course, when the pull rope 7 is not in use, it can be wound up by the cooperation of the correction seat 6 and the protective cylinder 11 so that the pull rope 7 can be wound up into the storage chamber 13.

[0036] It should be noted that a storage chamber 13 is formed between the straightening seat 6 and the protective cylinder 11. The storage chamber 13 can restrict the winding rope 7 after it is wound up, so as to prevent the winding rope 7 from falling off the straightening seat 6.

[0037] Example 5 After the pull rope 7 is wound up in the above embodiment four, the pull rope 7 usually falls downwards due to its own weight, causing the protective cylinder 11 to rotate as well, resulting in the wound pull rope 7 continuously loosening. Therefore, in order to overcome this technical problem, an improvement is made based on embodiment four. A ratchet 14 is fixed on the upper circumferential surface of the protective cylinder 11, and a rotating shaft 15 is fixed on the bottom of the suspension plate 2. A ratchet tooth 16 that works with the ratchet 14 is installed on the rotating shaft 15. When the ratchet 14 and the ratchet tooth 16 are engaged, they play a role in locking the protective cylinder 11 in one direction, so that the protective cylinder 11 can only rotate in one direction, which can prevent the rope 7 from falling downward due to gravity.

[0038] In detail: A stepped hole 1601 is provided in the center of the ratchet 16, and a torsion spring 1602 is installed inside the stepped hole 1601; a blocking shaft 1603 is fixed on the stepped hole 1601 and the rotating shaft 15 respectively, and the two blocking shafts 1603 abut against the two ends of the torsion spring 1602 respectively; the torsion spring 1602 is provided to drive the ratchet 16 and prevent the ratchet 16 from disengaging from the ratchet wheel 14 during use.

[0039] The method of using the air conditioning unit suspension device is as follows, referring to Embodiments 1 to 4; including the following steps: S1: The air conditioning unit is placed on the support plate 1 in advance; The air conditioning unit is placed at the center of the top of the support plate 1 and is located between several fixing ribs 3 to facilitate subsequent suspension work; S2: Adjust the length and orientation of the traction rope 4 according to the gravity distribution of the air conditioning unit; The protective cylinder 11 rotates relative to the correction seat 6 so that part of the traction rope 4 can be wound onto the correction seat 6, thereby adjusting the length of the traction rope 4. In addition, since the correction seat 6 is rotating, the position of the connection between the traction rope 4 and the protective cylinder 11 will also change direction, thereby adjusting the connection position between the traction rope 4 and the correction seat 6 so that the force is even when the traction rope 4 pulls the corresponding two correction components 8.

[0040] S3: The adjusted traction rope 4 is hung on the two corresponding correction components 8; Pull the traction rope 4 into a triangular structure so that the two ends of the lower part of the traction rope 4 are respectively hung on two correction components 8 (including two corresponding correction seats 8 or two adjacent correction seats 8).

[0041] S4: The suspension device supporting the air conditioning unit is lifted and transported using hoisting equipment; When the hoisting device is suspended at a high altitude, the traction rope 4 pulls on the unbalanced end of the bearing plate 1 to reduce the uneven load on the bearing plate 1.
