Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer installation equipment, in particular to an auxiliary lifting device for transformer installation. Background Art
[0002] The technical background of auxiliary lifting devices for transformer installation is usually closely related to the construction and maintenance of power systems. With the growth of electricity demand, the size and weight of transformers are also increasing. Transformers may need to be installed in various complex environments, such as narrow spaces, high-altitude operations or rugged terrain. These environments place higher demands on the design of lifting equipment. In the power industry, safety is always the primary consideration. There are many risks in the process of transformer lifting, such as equipment damage and personal injury. Therefore, professional lifting devices are needed to reduce these risks. Traditional transformer installation methods may take a long time, affecting the restoration of power supply and the commissioning of new facilities. Therefore, there is a need for equipment that can complete lifting tasks quickly and efficiently. With the rise in labor costs, reducing dependence on manpower has become an important direction for reducing installation costs. Automated and mechanized lifting devices can reduce the number of on-site workers.
[0003] In actual use, complex structures may require more materials and manufacturing processes, which will increase production costs and affect the market competitiveness of the lifting device. Complex structures may make maintenance and inspection more difficult, requiring more professional knowledge and skills, increasing maintenance costs and time. Components that are not strong enough may not be able to withstand the weight of the transformer or the impact force during the lifting process, increasing the risk during the lifting process. If the components of the lifting device are not strong enough or the design is not flexible enough, it may not be able to adapt to transformers of different models and sizes, limiting its scope of application. A structure that is not simple enough may cause the lifting device to have poor stability during the lifting process, and it may be easy to shake or tilt, affecting the safety and accuracy of the lifting. If the operating steps of the lifting device are complicated, more training and guidance may be required, increasing the user's learning cost. The complex structure may cause the lifting device to take up more space during transportation, increasing transportation costs and difficulty. Utility Model Content
