Generally, the width direction of the bottom of the boiler hearth is of a funnel-shaped structure, and the width of the bottom of the boiler hearth is about half of the width of the upper part of the hearth, namely, the width of the boiler hearth is limited when the bottom of a overhauling lifting platform of the boiler hearth is installed. The water cooling screen is designed at the middle upper part of most boiler furnace, the extension amount of the water cooling screen is different, and the water cooling screen is mostly close to the central line of the width direction, so that the designed boiler furnace overhauling lifting platform basically adopts a structure of a main platform and a plurality of auxiliary platforms, the auxiliary platforms are also called auxiliary baskets, and the telescopic or turnover structure is adopted, so that the area of the platform is reduced at the bottom of the furnace, and the size requirement of the bottom of the boiler furnace is met.
The number and the interval difference of the water cooling screens designed in the boiler furnace are large, and the auxiliary basket of the lifting platform can only be overhauled aiming at the actual design furnace in the furnace. After the boiler is used for a period of time, the water-cooling screen can be greatly deformed in the vertical direction, for example, an auxiliary basket at a fixed position is adopted, and the water-cooling screen can be rubbed with the water-cooling screen when the platform is lifted, so that the water-cooling screen is damaged or the platform is lifted.
