Detachable assembling platform and furnace shell welding alignment method

Abstract

The invention relates to a detachable assembling platform. A plurality of main beams are distributed along the center point of an inner round piece in an annular array mode; adjacent main beams are connected through a plurality of auxiliary beams, and a ring-shaped structure is formed by the auxiliary beams on the outer side of the inner round piece so as to support the main beams. A furnace shell welding alignment method includes the steps that pouring or leveling and compaction are carried out on an assembling site, a gradienter is erected, the assembling platform is assembled, the elevation error of the assembling platform is controlled through the gradienter, and a bolt is screwed to complete assembling of the assembling platform. A limiting groove is welded, a furnace shell is placed into the limiting groove, a fixing clamp is welded, preliminary alignment on the furnace shell is carried out, and then welding is carried out after the diameter and the concentricity of the furnace shell are controlled to be within the allowed deviation area through the methods of the gradienter and the center line. The platform is designed to be in an assembled mode so that the preparing time in the installation site can be shortened; meanwhile, repeated utilization can be carried out, so that the construction cost is reduced, and the market competitive capacity is increased. The installation quality of the furnace shell is guaranteed, the assembling speed of the furnace shell is guarantee, and meanwhile the manual consumption for furnace shell assembling is reduced.

Description

technical field [0001] The invention relates to the field of installation of industrial building steel structures, in particular to a detachable assembly platform and a furnace shell welding alignment method. Background technique [0002] In the field of steel structure installation in industrial buildings, the shells of blast furnaces and hot blast stoves are generally made in pieces in the factory and then transported to the installation site for installation. In order to ensure the progress and quality of on-site installation, it is necessary to assemble the flaky furnace shells on the ground and then hoist them as a whole. However, the current assembled platform structure mainly has defects such as complex structure, inability to be reused, difficulty in leveling and low welding precision. Contents of the invention [0003] In view of the technical problems existing in the prior art, the object of the present invention is to provide a furnace shell welding and alignme...
