Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance technology, specifically to an auxiliary lifting machine for electrical equipment maintenance. Background Technology

[0002] In modern life, household appliances are widely used and have penetrated into all aspects of people's lives, from kitchen appliances for daily cooking to air conditioners for regulating indoor temperature and refrigerators for storing food. However, these devices inevitably malfunction during long-term use and require repair. During the repair process, repair personnel often face the challenge of raising the equipment to a suitable height for operation. Therefore, the use of auxiliary lifting machines is particularly necessary, as it can greatly improve the convenience and efficiency of repairs, reduce the workload of repair personnel, and allow repair operations to be carried out more smoothly.

[0003] Traditional maintenance assistance technologies have drawbacks. In terms of mobility, previous equipment often lacked convenient mobile design, requiring maintenance personnel to spend a lot of time and energy transporting equipment to the maintenance site. The angle adjustment function was also extremely limited, making it difficult to meet the diverse needs of equipment angle in complex maintenance scenarios. This made it difficult to accurately locate the faulty part during maintenance. The lifting operation was also fraught with problems. Either the lifting accuracy was insufficient, making it difficult for maintenance personnel to work at the appropriate height, or the stability during the lifting process was poor, posing a risk of damaging the equipment. In addition, the support structure lacked flexibility, could not adapt to equipment of different shapes and sizes, and could not provide reliable support. These shortcomings seriously affected maintenance efficiency, prolonged maintenance cycle, increased maintenance costs, and also reduced maintenance quality, and may even cause secondary damage to the equipment. To address these issues, we propose an auxiliary lifting machine for electrical equipment maintenance. Utility Model Content
