Support beam device for fixing boiler furnace water wall

Abstract

The invention discloses a support beam device for fixing boiler furnace water walls. The support beam device for fixing the boiler furnace water walls is characterized in that the support beam devicecomprises a water wall tube; the water wall tube with the outer side affixed with a backing plate is connected by fins to form a square structure; a ribbed slab one with the outer side connected withfasteners is connected to the outer side of the backing plate; a base plate with the outer side connected with a panel through a connecting plate is disposed between the fasteners; an extension boardone is connected to both ends of the backing plate; the outer sides of adjacent extension boards are connected with a fixed plate; both ends of the connecting plate are connected with an extension board two which is hinged with a flat plate; the other end of the flat plate is hinged with the connecting plate; upper and lower sides of the backing plate are provided with support lugs; both ends of the support lugs are connected to the outer wall of the water wall tube; a pin shaft is inserted between the upper and lower support lugs. The support beam device for fixing the boiler furnace water walls has the advantages that a main structure of a support frame is welded in a boiler factory, and only welding of joints is required at the site with a little workload; accessories on the water wallare also completed in the factory, so that welding of the water wall at the site is avoided; assembly is convenient; good use effect is achieved.

Description

technical field [0001] The invention relates to a boiler supporting device, in particular to a supporting beam device used for fixing the boiler furnace water wall, and belongs to the technical field of boiler equipment. Background technique [0002] Boilers are widely used in thermal power station projects to burn coal to generate high-pressure steam, and then drive steam turbines to generate electricity through steam. It is one of the most important energy sources in national production. type structure to ensure the thermal expansion of the boiler. Since the water-cooled wall tubes of the boiler are long, they will be deformed during transportation. Poor, the production workload on the site is heavy, and the construction quality cannot be guaranteed. How to provide a support beam with a simple structure, less on-site construction workload, easy installation, and ensure the correction and fixation of the water-cooled wall is a problem that needs to be solved on site. .
