[0002] With the continuous advancement of technology, the conflict between urban population growth and land resources has led modern urban planning to focus on the intensive use of land and the three-dimensional development of urban space, encouraging the construction of high-rise buildings to optimize urban spatial layout. Through rational planning, placing multi-story and high-rise buildings in city centers or near transportation hubs can improve the overall function and operational efficiency of the city, forming a compact and efficient urban form. However, multi-story and high-rise buildings also have certain drawbacks. For example, high-rise buildings significantly increase evacuation time in emergencies such as earthquakes and fires, make high-rise fire fighting more difficult, and reduce the efficiency of external rescue efforts.

[0003] In existing technologies, multi-story and high-rise buildings lack emergency assistance functions. Although refuge floors (high-rise buildings) and fire rescue windows (multi-story and high-rise buildings) are provided, the self-rescue methods available to residents and users in response to emergencies are very limited. In extreme cases where escape routes fail, residents lack effective self-rescue methods.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] To address the problem that existing technologies often lack emergency auxiliary functions in multi-story and high-rise buildings, resulting in limited self-rescue methods for residents in the event of emergencies and a lack of effective self-rescue options in extreme situations, this utility model provides a safety device that integrates the installation, maintenance, and emergency escape of an outdoor air conditioning unit.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0031] In the current technology, multi-story and high-rise buildings lack emergency auxiliary functions. Although high-rise buildings are equipped with refuge floors and fire rescue windows, the self-rescue methods that residents and users can use in response to emergencies are very limited. In extreme cases where escape routes fail, residents lack effective self-rescue methods.

[0032] Based on the aforementioned problems in the existing technology, this utility model provides a safety device that integrates the installation, maintenance, and emergency escape of an air conditioner outdoor unit, such as... Figure 1 and Figure 2 As shown, the safety device for installation, maintenance, and emergency escape of the integrated air conditioner outdoor unit includes: an escape platform 200, which is anchored to the structural column 100; a structural beam 300, which is set at predetermined intervals directly below the escape platform 200, and the space between the structural beam 300 and the escape platform 200 forms the air conditioner unit position 320; and a lifting ring 400, part of which is pre-embedded inside the structural beam 300, with the lifting ring 400 corresponding to the position of the lower escape platform 200.

[0033] This utility model establishes an escape platform 200 on the structural column 100, forming a mezzanine space with the structural beam 300 to create an air conditioner unit 320. A hanging ring 400 structure is pre-embedded in the structural beam 300, with the portion of the hanging ring 400 protruding from the structural beam 300 corresponding to the position of the escape platform 200 on the next floor. This allows for the fixation of a safety rope 500. The system can be used for the installation, cleaning, and dismantling of the outdoor air conditioner unit, as well as for refuge and escape in emergencies, providing residents with an effective self-rescue method and improving the rescue rate.

[0034] In this embodiment, as Figure 1 and Figure 2As shown, the main body of this utility model's integrated safety device for air conditioner outdoor unit installation, maintenance, and emergency escape consists of an escape platform 200, a structural beam 300, and a lifting ring 400. The escape platform 200 is anchored to the structural column 100. In the prior art, both the structural column 100 and the structural beam 300 are load-bearing components of multi-story and high-rise buildings. Therefore, this utility model is based on the existing structure in the prior art. In actual installation, the escape platform 200 is positioned at a predetermined distance directly above the structural beam 300. The space between the escape platform 200 and the structural beam 300 is the air conditioner unit location 320. Correspondingly, in this utility model, a lifting ring 400 is pre-embedded during the construction of the structural beam 300. The circular portion of the lifting ring 400 is exposed, while a portion of the lifting ring 400 is pre-embedded inside the structural beam 300. Figure 2 As shown, in high-rise buildings, the basic structure of each floor is the same. Therefore, the lifting ring 400 installed on the structural beam 300 in the upper floor can correspond to the escape platform 200 in the lower floor. Since the lifting ring 400 is embedded in the structural beam 300 and has stable load-bearing capacity, it can be used as a suspension point for the safety rope 500 of the operator when installing, cleaning and dismantling the outdoor unit of the air conditioner. It can also be used as a suspension point for the escape rope in case of emergency.

[0035] In one possible embodiment of this utility model, such as Figure 2 As shown, the aforementioned structural beam 300 includes a sealing beam 310. A reinforcing steel structure is pre-installed inside the structural beam 300 to ensure load-bearing strength. The shape of the reinforcing steel structure is adapted to the shape of the structural beam 300; that is, a reinforcing steel structure is also provided inside the sealing beam 310 of the structural beam 300. The aforementioned lifting ring 400 is installed on the sealing beam 310, preferably inside the sealing beam 310 of the structural beam 300 to prevent corrosion damage caused by wind and rain. Specifically, the lifting ring 400 includes an exposed ring body 410 exposed on the outside of the structural beam 300 and an installation rod 420 embedded inside the sealing beam 310. The installation rod 420 is wound and engaged with the reinforcing steel inside the sealing beam 310, ensuring the stability and load-bearing capacity of the lifting ring 400. The exposed ring body 410 is partially exposed on the outside of the structural beam 300, facilitating the connection of the safety rope 500 or other rescue equipment by the operator. This design not only enhances the robustness of the lifting ring 400 but also ensures its safety and reliability during long-term use. Furthermore, by rationally arranging the position and number of the lifting rings 400, the effectiveness of this safety device in emergency situations can be further optimized, providing residents and users in multi-story and high-rise buildings with a more comprehensive and effective emergency escape route.

[0036] Furthermore, such as Figure 2As shown, the exposed ring 410 is preferably U-shaped, with two integrally formed mounting rods 420 on both ends of the exposed ring 410. The two mounting rods 420 are positioned opposite each other and are wound and engaged with the corresponding reinforcing bars. This arrangement of the mounting rods 420 further enhances the connection stability between the lifting ring 400 and the structural beam 300, enabling the lifting ring 400 to withstand greater tensile force, thereby improving the reliability and safety of the entire safety device. In an emergency, residents can quickly use the lifting ring 400 to connect to the safety rope 500 or the descent device 510 and evacuate quickly and safely via the escape platform 200. Simultaneously, the maintenance passage provides convenience for the daily maintenance and repair of the air conditioner outdoor unit, allowing operators to work efficiently while ensuring safety. The escape passage formed by the window 210 and the escape platform 200 further broadens the residents' escape routes, improving the flexibility and versatility of emergency escape.

[0037] In the above embodiment, the lifting ring 400 should be made of S31608 stainless steel, which is processed into a lifting ring 400 with a diameter of Φ10. This lifting ring 400 possesses excellent tensile properties, with a tensile strength of not less than 520MPa, ensuring extremely high structural safety. The control of the embedded depth strictly follows the specific requirements of Article 9.7.4 of the "Code for Design of Concrete Structures" GB50010, ensuring the depth and stability of the embedded portion. The anchorage length is strictly controlled according to the standard of 20d, where d represents the diameter of the reinforcing steel used in the fabrication of the lifting ring 400. This standard effectively guarantees the reliability of the anchorage.

[0038] In another possible embodiment of this utility model, such as Figure 3 As shown, the safety device for installation, maintenance, and emergency escape of the aforementioned integrated air conditioner outdoor unit also includes a safety rope 500 and a descent device 510. One end of the safety rope 500 is detachably connected to the lifting ring 400, and the other end can be connected to the operator's safety belt or other fixed point, facilitating quick operation by staff or users during escape. The descent device 510 is detachably mounted on the safety rope 500, allowing the operator to safely descend to the ground or the next floor while controlling the descent speed.

[0039] In this embodiment, the safety rope 500 must be made of high-performance Kevlar fiber. This escape rope has a diameter of 12mm and possesses extremely high breaking strength, not less than 25kN, meeting the requirements of the XF494 "Fighting Fall Protection Equipment" standard. The top of the escape rope is reliably connected to the stainless steel eyelet 400 via a robust alloy steel shackle (compliant with GB / T25854 "General Lifting D-type and Bow-shaped Forged Shackles" standard), ensuring the strength and durability of the connection.

[0040] In this embodiment, the descent control can specifically be the AL-8634 model. The selection of the descent control should ensure that the descent speed can be flexibly adjusted within the range of 0.8-1.2 m / s during use. Its rated load range is wide, covering 50-120 kg, which can meet the needs of different users. The coefficient of friction of the brake pads is not less than 0.35. This performance indicator is obtained through rigorous testing according to the GB / T19089 standard "Determination of Abrasion Resistance of Rubber or Plastic Coated Fabrics - Martindale Method", ensuring the stability and reliability of the braking effect.

[0041] In another possible embodiment of this utility model, such as Figure 1 As shown, in multi-story and high-rise buildings, masonry exterior walls 600 are respectively set on both sides of the structural beam 300. In this embodiment, the masonry exterior walls 600 serve as a connecting structure for the escape platform 200 and also connect with the structural beam 300 to form a load-bearing structure for the building. In this embodiment, an outer corridor railing 610 is also set on the outside of the masonry exterior walls 600, forming a maintenance passage between the masonry exterior walls 600 and the outer corridor railing 610. This maintenance passage corresponds to the position of the escape platform 200, facilitating the installation and maintenance of air conditioning outdoor units. The setting of the maintenance passage not only improves the convenience of air conditioning outdoor unit installation and maintenance but also provides an additional escape route in emergency situations, further enhancing the practicality and emergency response capability of the entire safety device.

[0042] More specifically, the outer corridor railing 610 is located 0.6m to 0.8m outside the masonry outer wall 600. A guide pulley for securing the safety rope 500 is installed on the outer corridor railing 610. The guide pulley guides the safety rope 500 along a specific path, preventing it from becoming entangled or rubbing during emergency escapes, thus ensuring its effectiveness. The guide pulley is preferably made of wear-resistant and corrosion-resistant materials to ensure its long-term stability and reliability. Furthermore, the installation position of the guide pulley is carefully designed to ensure that, in an emergency, operators can quickly and smoothly use the safety rope 500 to escape.

[0043] In one possible embodiment of this utility model, such as Figure 1 and Figure 2As shown, a window 210 is installed between the structural column 100 and the masonry exterior wall 600. The window 210 corresponds to the escape platform 200, forming an escape passage between them. The window 210 not only increases indoor lighting and ventilation, but more importantly, in an emergency, it can serve as an additional escape exit, forming a spacious and convenient escape route together with the escape platform 200. Operators or residents can quickly transfer to the escape platform 200 through the window 210 and then safely evacuate using the hanging rings 400 and safety ropes 500. This ingenious combination of the window 210 and the escape platform 200 further enhances the emergency escape capability of the entire safety device.

[0044] In another possible embodiment of this utility model, such as Figure 2 As shown, ventilation louvers 330 are installed between the structural beam 300 and the escape platform 200. The two sides of the ventilation louvers 330 are bolted to the structural beam 300 and the escape platform 200 respectively to increase their stability. The railings of the ventilation louvers 330 are made of corrosion-resistant, high-strength materials to resist external environmental erosion and maintain their long-term safety and reliability. This design not only improves the overall safety performance of the safety device but also provides a safer living environment for residents in multi-story and high-rise buildings.

[0045] In another possible embodiment of this utility model, such as Figure 2 As shown, a reinforcing steel bar 340 is also provided at the connection point between the structural beam 300 and the lifting ring 400. The reinforcing steel bar 340 is fixedly connected to the lifting ring 400 to enhance the connection strength between the lifting ring 400 and the structural beam 300, ensuring the stability and safety of the lifting ring 400 during long-term use. In actual installation, the reinforcing steel bar 340 can be wrapped around the structural beam 300, which, in addition to fixing the lifting ring 400, also serves as a decorative surface on the building's exterior.

[0046] This makes the overall structure more aesthetically pleasing. The preferred material for the reinforcing steel bar 340 is Q345B low-alloy high-strength steel. This material not only possesses high strength and good toughness but also excellent weldability, ensuring a secure connection between the reinforcing steel bar 340 and the structural beam 300. The thickness of the reinforcing steel bar 340 is rationally designed based on actual needs and stress analysis to ensure sufficient load-bearing capacity, effectively resisting external forces and guaranteeing the long-term stability and safety of the lifting ring 400 and its connecting components.

[0047] In another embodiment of this invention, the surface of the escape platform 200 is provided with an anti-slip texture to increase the friction between the operator and the escape platform 200, preventing accidental injury due to slipping during an emergency escape. The anti-slip texture design fully considers ergonomics and safety, ensuring that the operator can stand stably and move quickly in an emergency.

[0048] Based on the above embodiments, the actual usage process of this utility model's integrated safety device for air conditioner outdoor unit installation, maintenance, and emergency escape is as follows:

[0049] In an emergency, residents or workers in a high-rise building can quickly reach the escape platform 200. The escape platform 200 is securely anchored to the structural column 100, providing a reliable base for standing and evacuation. They can then use the lifting rings 400 pre-installed on the structural beam 300 to securely attach one end of the safety rope 500 to the rings 400, and the other end to the worker's or resident's safety harness or other fixed point. With this setup, workers or residents can safely descend to the ground or the next floor by controlling their descent speed along the safety rope 500 using the descent control device 510.

[0050] Furthermore, the design of this safety device fully considers the convenience of daily maintenance and repair. Through the designated maintenance access, personnel installing and maintaining the outdoor air conditioning units can easily reach the escape platform 200 to perform their work, greatly improving work efficiency. At the same time, the addition of reinforcing steel bars 340 further enhances the safety performance and stability of the entire safety device, providing residents in high-rise buildings with a more secure living environment.

[0051] In summary, this utility model provides an integrated safety device for the installation, maintenance, and emergency escape of an air conditioner outdoor unit. This device includes: an escape platform anchored to a structural column; a structural beam positioned at predetermined intervals directly below the escape platform, with the space between the beam and the platform forming the air conditioner unit location; and a lifting ring, partially embedded within the structural beam, corresponding to the position of the lower-level escape platform. This utility model, by setting an escape platform on the structural column, creating a mezzanine space with the structural beam to form the air conditioner unit location, and embedding a lifting ring structure in the structural beam, with the exposed portion of the ring corresponding to the position of the escape platform on the next lower floor, allows for the securing of safety ropes. This device can be used for the installation, cleaning, and dismantling of air conditioner outdoor units, as well as for refuge and escape in emergencies, providing residents with an effective self-rescue method and improving the rescue rate.

[0052] It should be understood that the application of this utility model is not limited to the examples above.
