High-altitude assembly mounting device for boiler membrane water-cooled wall and mounting method of high-altitude assembly mounting device

Abstract

The invention relates to a high-altitude mounting process for a boiler membrane water-cooled wall, in particular to a high-altitude assembly mounting device for the boiler membrane water-cooled wall and a mounting method of the high-altitude assembly mounting device. The high-altitude assembly mounting device comprises a hanging device component, an upper-section water-cooled wall group, a lower-section water-cooled wall group, an upper-section rigid beam, a lower-section rigid beam, an upper-section lifting lug assembly, a lower-section lifting lug assembly, a chain block and an operation platform component. The upper-section water-cooled wall group is arranged on the lower portion of the hanging device component and is connected with the hanging device component, and the upper-section rigid beam is arranged on the side face portion of the upper-section water-cooled wall group and is fixedly connected with the upper-section water-cooled wall group. According to the high-altitude mounting method of the boiler membrane water-cooled wall, the sectional water-cooled wall is small in size, light in weight and safe and convenient to hoist, and the mounting and using requirements of mounting engineering enterprises for the boiler membrane water-cooled wall are greatly met.

Description

technical field [0001] The invention relates to a high-altitude installation process of a boiler membrane water-cooled wall, in particular to a high-altitude installation device and an installation method for a boiler membrane water-cooled wall. Background technique [0002] The water wall is the main heating part of the boiler, which is composed of several rows of steel pipes and distributed around the boiler furnace. Its inside is flowing water or steam, and the outside receives the heat of the flame in the boiler furnace. It mainly absorbs the radiant heat of the high-temperature combustion products in the furnace, and the working medium moves up in it, and evaporates when heated. Membrane water-cooled wall is to weld many rolled water-cooled finned tubes to each other by spot welding to form a sealed combined heating surface, which can not only improve the air tightness of the furnace, reduce air leakage, but also better protect The furnace wall reduces the weight of t...

Problems solved by technology

[0003]The water-cooled wall in large and medium-sized power plant boilers is the ultimate heating surface. It has the characteristics of large size, heavy weight, and high installation height. The existing large and medium-sized power plant boilers The usual construction method of the water-cooled wall is that first, the water-cooled wall is assembled into a whole piece on the ground prefabricated platform, and then the assembled whole piece-shaped water-cooled wall is hoisted in place by large-scale hoisting equipment. High performance requirements, high cost of construction machinery, and the required prefabricated platform area is large, and the overall construction cost is high
