Description

Technical Field

[0001] This utility model relates to the field of outdoor unit lifting machines, and in particular to an air conditioner outdoor unit lifting machine. Background Technology

[0002] The outdoor unit of an air conditioning system is a key component, and its structure mainly includes critical parts such as a compressor, condenser, throttling device, and fan. Its operating mechanism is based on the compressor compressing the refrigerant to form a high-temperature, high-pressure gas. The condenser then releases heat to the external environment, the throttling device further reduces the pressure and temperature, and finally, the fan transports the cooled refrigerant back to the indoor unit, completing the refrigeration cycle. In the field of construction machinery, vertical or inclined conveying equipment is usually referred to as a bracket lifting machine.

[0003] During application, bracket lifting machines may face stability issues in their design or manufacturing. When this equipment is used to lift outdoor air conditioning units, insufficient structural stability or load-bearing capacity will cause unstable shaking of the outdoor unit during the lifting process. Such shaking may not only damage the outdoor unit but also pose potential safety risks to the surrounding environment.

[0004] In addition, failure to follow standard operating procedures can also cause the outdoor unit to shake. For example, the operator may fail to ensure that the lifting device of the hoist is properly secured to the outdoor unit, or fail to maintain a uniform speed and stability during the lifting process; these improper operations can all cause the outdoor unit to shake.

[0005] Prolonged use of air conditioner outdoor units may lead to problems such as loose screws and aging brackets. These issues can exacerbate swaying when the outdoor unit is lifted. In particular, when the outdoor unit bracket is corroded or aged, its load-bearing capacity and stability will decrease significantly, thereby increasing swaying and safety risks.

[0006] Environmental factors can also affect the swaying of air conditioner outdoor units. For example, severe weather conditions such as strong winds and heavy rain may cause additional external forces to be applied to the outdoor unit during the lifting process, thus exacerbating the swaying. In addition, if the outdoor unit is installed near the edge of a building or there are other obstacles, it may be restricted or interfered with during the lifting process, thereby increasing swaying and safety risks.
