Abstract

The invention discloses a moving combing platform for detecting a heating screen in a circular fluidized bed boiler hearth, which comprises a transverse-H shaped main beam, a transverse-H shaped secondary beam, a transverse-H shaped lead rail beam, a fixing moving platform and a combing moving platform; the transverse-H shaped main beam is in parallel to a boiler wall, and the transverse-H shapedsecondary beam is perpendicular to the transverse-H shaped main beam installed on the transverse-H shaped main beam, and connected through main and secondary beam fasteners; the transverse-H shaped lead rail beam is installed on previous two a transverse-H shaped secondary beams of the boiler, and connected through the lead rail fixing fastener; the transverse-H shaped secondary beam is paved withan anti-slide aluminum alloy skipping plate, the fixing moving platform is installed on the transverse-H shaped lead rail beam; one end is connected with the combing moving platform and used for driving the combing moving platform to crossly move. The heating screen in the circular fluidized bed boiler hearth can be rapidly, safely and comprehensively overhauled.

Description

technical field [0001] The invention relates to a boiler furnace inspection and maintenance platform, in particular to a movable comb-shaped platform for inspection and maintenance of a heating panel in a circulating fluidized bed boiler furnace. Background technique [0002] At present, most of the boiler furnace maintenance in thermal power plants in my country adopts the boiler furnace maintenance platform. The boiler furnace maintenance platform has the characteristics of short installation period, convenient use and high safety. According to the classification of furnace type, coal-fired boilers can be divided into π-type coal-fired boilers, tower furnaces, W flame furnaces, and circulating fluidized bed boilers. Because the interior of the π-type coal-fired boiler, tower furnace, and W flame furnace are all hollow structures, which brings convenience to maintenance, several domestic manufacturers of boiler furnace maintenance platforms have relatively mature technolog...
