Description

Technical Field

[0001] This utility model relates to the field of air conditioner installation technology, specifically a portable lifting device for air conditioner installation. Background Technology

[0002] Air conditioning installation refers to the process of correctly and securely fixing air conditioning equipment (including indoor and outdoor units) in a designated location according to design requirements, technical specifications, and safety standards through a series of professional operations, and completing electrical connections, pipe connections, system debugging, and other work so that the air conditioning equipment can operate normally and achieve the expected functions such as cooling, heating, dehumidification, and ventilation.

[0003] An existing patent (publication number: CN215048208U) discloses a high-balance lifting device for air conditioner outdoor units, including an air conditioner outdoor unit and connecting buckles, as well as an anti-tilt and sway-balancing lifting mechanism. Connecting buckles are fixedly installed on both sides of the top of the air conditioner outdoor unit, and the anti-tilt and sway-balancing lifting mechanism is movably connected to the top of the telescopic connecting buckles. The anti-tilt and sway-balancing lifting mechanism includes a forward and reverse geared motor, a drive gear turntable, a driven gear turntable, a support shaft, a rope winding drum, an auxiliary bearing, a lifting rope, a fixing plate, a wall-supporting rod, and an auxiliary roller. The drive gear turntable is fixedly connected to the center through hole on one side of the forward and reverse geared motor via an output shaft. This invention achieves high stability when lifting the air conditioner outdoor unit, avoiding potential back-and-forth swaying that could cause contact and impact with the wall, resulting in damage or falling of the equipment and poor safety.

[0004] During use, the above-mentioned lifting device can avoid the problem of damage or falling of the equipment due to possible back-and-forth swaying and contact with the wall, which is a safety issue. However, since the auxiliary rollers and the wall support rod are in a horizontal state, they are easy to get stuck when they encounter the eaves of the building, which may affect the hoisting of the air conditioner outdoor unit. At the same time, when the above-mentioned lifting device is hoisting, the position of the air conditioner outdoor unit lacks protection, and it is easy to come into contact with the wall and be damaged during the hoisting process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a portable lifting device for air conditioner installation, which has advantages such as improved protection and stability during the lifting process, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable lifting device for air conditioner installation, comprising an air conditioner outdoor unit and a protective assembly snapped onto the surface of the air conditioner outdoor unit. The protective assembly includes a fixing member, which is snapped onto the air conditioner outdoor unit. Two rotating disks are rotatably connected to the back of the fixing member. A swing arm is hinged to the back of each of the two rotating disks. A rubber roller is rotatably connected to the upper end of each of the two swing arms. A damper is hinged to the back of each of the two rotating disks. The other end of each of the two dampers is hinged to the swing arm adjacent to it. Multiple rubber buffer rods are rotatably connected to the outer surface of the fixing member.

[0007] The above solution, through the coordination of the swing arm and rubber rollers, allows the swing arm to swing naturally, flexibly avoiding obstacles such as eaves and waistlines during hoisting, thus preventing contact with them and hindering the hoisting work.

[0008] Furthermore, both of the inclined surfaces of the swing arms are ball-connected with multiple contact balls.

[0009] By using the above method, the contact ball can reduce the friction between the swing arm and the wall or waistline, making it easier for the swing arm to swing normally.

[0010] Furthermore, both rotating disks are connected to the fixing components by bolts.

[0011] The above solution uses bolts to fix the rotating disk, which can prevent the rotating disk from rotating during the hoisting process and avoid affecting the hoisting work.

[0012] Furthermore, each end of the fastener is fixedly connected to a lifting strap, and the two lifting straps are fastened together by a buckle at their close ends.

[0013] The above solution involves setting up a hoisting strap to limit the position of the fasteners, ensuring that they can be stably installed onto the outdoor unit of the air conditioner.

[0014] Furthermore, a second hoisting strap is provided on the outer surface of the outdoor unit of the air conditioner, and a set of traction cables is fastened to the upper surface of the second hoisting strap.

[0015] By using the above method, the second hoisting sling can be installed to secure the outdoor unit of the air conditioner, ensuring that the hoisting work can be carried out stably.

[0016] Furthermore, multiple support frames are provided above the outdoor unit of the air conditioner. Each of the two support frames located on opposite sides is rotatably connected to a winding rod. Multiple traction cables are fixedly connected to the winding rods located close to each other. A dual-axis motor is installed on the inner wall of the support frame located in the middle. Both winding rods are fixedly connected to the output end of the dual-axis motor. Multiple support frames are fixedly connected to the external wall.

[0017] The above scheme, which includes a dual-axis motor and a winding rod, enables the winding of the traction cable, allowing the traction cable to be used for hoisting two pairs of air conditioner outdoor units via a hoisting belt.

[0018] Furthermore, the multiple rubber buffer rods are arranged in a matrix.

[0019] With the above solution, the rubber buffer bars are distributed in a matrix, which can protect the outdoor unit of the air conditioner over a large area and prevent the outdoor unit from contacting the wall and causing damage during hoisting.

[0020] Furthermore, the second hoisting strap makes a wrapping contact with the outdoor unit of the air conditioner.

[0021] With the above solution, the second hoisting sling makes a wrapping contact with the outdoor air conditioner unit, which can wrap around the outdoor air conditioner unit, increase the contact connection with the outdoor air conditioner unit, and enable the outdoor air conditioner unit to be stably located inside the second hoisting sling.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0023] This portable lifting device for air conditioner installation, through the cooperation of a swing arm and rubber rollers, can flexibly avoid obstacles such as eaves and waistlines during hoisting by naturally swinging the arm, preventing contact with them and ensuring smooth hoisting. A rotating disc can change the angle of the swing arm, providing protection for the outdoor unit during both upward and downward hoisting. The damper and rubber buffer rod work together to form a good buffer system, effectively cushioning external impacts and preventing damage to the outdoor unit from collisions with walls during hoisting, providing reliable protection. The multiple traction cables design ensures even distribution of hoisting force, reducing the swing amplitude of the outdoor unit during hoisting, improving stability and safety, and making the air conditioner outdoor unit hoisting work more efficient, safe, and reliable.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment discloses a portable lifting device for air conditioner installation, comprising an air conditioner outdoor unit 1 and a protective assembly 2 snapped onto the surface of the air conditioner outdoor unit 1. The protective assembly 2 includes a fixing member 201, which is snapped onto the air conditioner outdoor unit 1. Two rotating disks 202 are rotatably connected to the back of the fixing member 201. A swing arm 203 is hinged to the back of each of the two rotating disks 202. A rubber roller 204 is rotatably connected to the upper end of each of the two swing arms 203. A damper 205 is hinged to the back of each of the two rotating disks 202. The other end of each damper 205 is hinged to the adjacent swing arm 203. Multiple rubber buffer rods 206 are rotatably connected to the outer surface of the fixing member 201. By setting the swing arm 203 and the rubber roller 204 in cooperation, the swing arm can... The natural swing of the swing arm 203 allows it to flexibly avoid obstacles such as eaves and waistlines during hoisting, preventing contact with them and ensuring smooth hoisting operations. The rotating disc 202 allows the angle of the swing arm 203 to be changed, providing protection for the air conditioner outdoor unit 1 during both upward and downward hoisting. The damper 205 and rubber buffer rod 206 work together to form a good buffer system, effectively cushioning external impacts and preventing the air conditioner outdoor unit 1 from colliding with and being damaged by the wall during hoisting, providing reliable protection for the air conditioner outdoor unit 1. The design of multiple traction cables 6 ensures even distribution of hoisting force, reducing the swing amplitude of the air conditioner outdoor unit 1 during hoisting, improving the stability and safety of the hoisting, and making the hoisting of the air conditioner outdoor unit 1 more efficient, safe, and reliable.

[0034] Please see Figure 1 , Figure 2 and Figure 3Both swing arms 203 have multiple contact balls 3 on their inclined surfaces. The contact balls 3 reduce the friction between the swing arms 203 and the wall or waistline, facilitating the normal swing of the swing arms 203. Both rotating disks 202 are connected to the fixing member 201 by bolts. The bolt fixing of the rotating disks 202 can prevent the rotating disks 202 from rotating during the hoisting operation, thus avoiding the rotation of the rotating disks 202 from affecting the hoisting operation. Both ends of the fixing member 201 are fixedly connected to the hoisting straps 4. The two hoisting straps 4 are fastened to each other by a buckle. The hoisting straps 4 can limit the fixing member 201, so that the fixing member 201 can be stably installed on the air conditioner outdoor unit 1.

[0035] Please see Figure 1 , Figure 2 and Figure 4 The outdoor unit 1 of the air conditioner is equipped with a second hoisting sling 5 on its outer surface. A set of traction cables 6 are fastened to the upper surface of the second hoisting sling 5. The second hoisting sling 5 can restrain the outdoor unit 1 of the air conditioner, so that the hoisting work can be carried out stably. Multiple support frames 7 are set above the outdoor unit 1. The support frames 7 on both sides are rotatably connected to the side of each other with a winding rod 8. Multiple traction cables 6 are fixedly connected to the winding rods 8 that are close to each other. A dual-shaft motor 9 is installed on the inner wall of the support frame 7 in the middle. The two winding rods 8 are fixedly connected to the output end of the dual-shaft motor 9. Multiple support frames 7 are fixedly connected to the external wall. The shaft motor 9 and the winding rod 8 can wind up the traction cable 6, allowing the traction cable 6 to be used to hoist the air conditioner outdoor unit 1 via the hoisting sling 2 5. Multiple rubber buffer rods 206 are arranged in a matrix, which can protect the air conditioner outdoor unit 1 over a large area, preventing damage caused by contact between the air conditioner outdoor unit 1 and the wall during hoisting. The hoisting sling 2 5 has a covering contact with the air conditioner outdoor unit 1, which can wrap around the air conditioner outdoor unit 1, increase the contact connection with the air conditioner outdoor unit 1, and allow the air conditioner outdoor unit 1 to be stably located within the hoisting sling 2 5.

[0036] This embodiment of a portable lifting device for air conditioner installation, through the cooperation of a swing arm 203 and rubber rollers 204, allows the swing arm 203 to flexibly avoid obstacles such as eaves and waistlines during hoisting, preventing contact with them and ensuring smooth hoisting. The rotating disc 202 changes the angle of the swing arm 203, providing protection for the air conditioner outdoor unit 1 during both upward and downward hoisting. The damper 205 and rubber buffer rod 206 work together to form a good buffer system, effectively buffering external impacts and preventing the air conditioner outdoor unit 1 from colliding with and being damaged by the wall during hoisting, providing reliable protection for the air conditioner outdoor unit 1. The design of multiple traction cables 6 ensures even distribution of hoisting force, reducing the swing amplitude of the air conditioner outdoor unit 1 during hoisting, improving the stability and safety of the hoisting, and making the hoisting of the air conditioner outdoor unit 1 more efficient, safe, and reliable.

[0037] The working principle of the above embodiment is as follows: First, the fixing component 201 is installed on the outdoor unit 1 of the air conditioner, and the fixing component 201 is fixed using the first hoisting sling 4. Then, the outdoor unit 1 is secured using the second hoisting sling 5 to keep it stable. Finally, the dual-shaft motor 9 drives the two winding rods 8 to rotate, so that the winding rods 8 can wind up the traction cable 6. When the traction cable 6 is wound up, the outdoor unit 1 of the air conditioner will be pulled up. The swing arm 203 is set up so that it can cooperate with the rubber roller 204. The natural swing of the swing arm 203 can flexibly avoid obstacles such as eaves and waistlines during hoisting, and avoid contact with them to prevent the hoisting work from being hindered. To ensure the smooth progress of the hoisting work, the angle of the swing arm 203 is adjusted by rotating the disc 202 before hoisting, so that it can provide protection for the air conditioner outdoor unit 1 whether it is hoisting upwards or downwards. During the hoisting process, multiple traction cables 6 are used to distribute the hoisting force evenly, reduce the swing amplitude of the air conditioner outdoor unit 1 during the hoisting process, improve the stability and safety of the hoisting, and make the hoisting of the air conditioner outdoor unit 1 more efficient, safe and reliable. The damper 205 and the rubber buffer rod 206 work together to form a good buffer system, effectively buffering the external impact force and preventing the air conditioner outdoor unit 1 from colliding with the wall and being damaged during hoisting, thus providing reliable protection for the air conditioner outdoor unit 1.
