Its height is generally 3.5 - 4 meters, the weight is 1 - 2 tons, the oil pump weighs about 150 kg, and the height is about 85 cm. During the major overhaul of the main transformer, it is necessary to replace the seals of the main transformer oil-water cooler, inspect the inside of the water circuit and oil circuit, and may replace the oil pump, etc. For this reason, a scaffolding platform for standing people needs to be erected. At present, the platform is erected using a steel pipe fastener scaffolding. Erecting a steel pipe scaffolding is not only difficult, but also makes the ground operation environment more narrow and complex due to the large occupied space, and increases the risk of damage to adjacent equipment. In order to reduce the maintenance operation risk of the transformer oil-water cooler in a narrow space, reduce the construction difficulty and workload, it is necessary to design and manufacture a modular lifting platform with the function of lifting components according to the on-site conditions to eliminate the ground support, meet the maintenance requirements, save space to the greatest extent, and reduce the maintenance operation risk.
