Problems solved by technology

However, during the assembly and welding process of large and ultra-large gas-cooled separator cylinders with a maximum diameter of more than 8 meters, due to the large-scale gas-cooled separator cylinders are heavy and bulky, if the integral welder supported by the central shaft It is necessary to design huge tooling, and at the same time, some assembly and welding operations need to be operated at a height of more than 8 meters, which is inconvenient for assembly and welding work, and there is a greater safety hazard

Embodiment Construction

[0016] See figure 2 , image 3 , Figure 4 and Figure 5 As shown, a welding tooling includes a base plate 1 and an arc positioning plate 2. The arc positioning plate 2 is spliced ​​by three arc blocks 2-1, and the outer peripheral surface of the arc positioning plate 2-1 has an arc Groove 2-2 plays a role in locating the separator pipe during assembly. The base plate 1 includes an arc plate 1-1 corresponding to the arc positioning plate 2 and a T-shaped supporting steel 1-2 connecting the arc plate 1-1.

[0017] The arc positioning plate 2 is provided with a first connection hole 3, and the arc plate 1-1 is provided with a second connection hole 4 corresponding to the first connection hole 3, and the arc positioning plate 2 and the arc plate 1-1 are connected by bolts. Nuts cooperate to realize the connection; the first connection hole 3 is a waist hole, and the second connection hole 4 is two threaded holes side by side; the arc positioning plate 2 and the arc plate 1-1 ...

Abstract

The invention relates to the field of assembling and welding tools of large steam cold separator barrels, in particular to an assembling and welding tool and a steam cold separator barrel installing structure using the tool. The assembling and welding tool and the steam cold separator barrel installing structure are convenient to work, safe and reliable; a base plate and an arc positioning plate which are connected are included, the arc positioning plate is formed by splicing at least two arc blocks, and arc grooves are formed in the peripheral face of the arc positioning plate; and the base plate comprises an arc plate corresponding to the arc positioning plate and supporting structural steel connected with the arc plate.

Description

technical field [0001] The invention relates to the field of assembly and welding tooling for large-scale steam-cooled separator cylinders, in particular to an assembly and welding tool and an installation structure for a gas-cooled separator cylinder using the tooling. Background technique [0002] The steam-cooled cyclone separator is one of the important components of the circulating fluidized bed boiler. It has large volume, complicated assembly, high manufacturing precision and heavy welding workload. The final assembly and welding of the steam-cooled cyclone separator requires matching tooling templates to ensure its assembly position and post-welding accuracy. Generally, small and medium-sized gas-cooled separators use integral welding fixtures, supported by the central shaft, and mounted on the brackets at both ends. When welding pipes and flat steel, the integral welding fixtures can be rotated. , so as to ensure convenient and safe operation during manual welding....
