It is a, it sets up temporary support and stage+module at 600mm, is uniformly installed 16 ring-shaped platforms and stretched under the furnace shell collar extension for needing to weld
Contracting leg 3.
(2) round hanging platform production on furnace shell
Round hanging platform construction figure is drawn according to furnace shell diameter, determines each portion's size of platform, is made and is justified according to construction drawing
Type ring-shaped platform 4 one, platform diameter is greater than 4 meters of furnace shell diameter, is uniformly arranged 8 suspension centres 5, completely spreads 5mm thick steel plate on platform
Sealing welding, surrounding set up railing.
(3) electric hoisting mechanism
According to weight such as ring shaped movable platform, construction personnel, welding machine, wldings, 8 electric blocks 6 are uniformly arranged, by matching
Electric cabinet 7 controls electric block single action or linkage, and power distribution cabinet 7 is fixed on round hanging platform.
(4) each section combination installation
Ring shaped movable platform 1 is mounted on furnace shell outer wall to be welded and is fixed temporarily first, secondly by electric block 6
And power distribution cabinet 7 is mounted on round hanging platform 4, again by round hanging platform (4) integral hoisting in furnace shell suitable for reading, power distribution cabinet
7 power on electric block 6 are made to tangle ring shaped movable Platform Lug 2, raising as needed or reduce ring shaped movable platform, pass through
Ring-shaped platform Retractive leg (3) adjusts platform and furnace shell gap, is laid with springboard and asbestos cloth when being greater than 100mm, platform raising is in place
It is rigidly fixed on furnace shell with connecting rod afterwards, is carrying out the work such as furnace shell welding.
(5) it is recycled
It is next in progress after the completion of each pair of dress 4-5 band of furnace shell is as a cycle welding use in furnace shell erection stage
In the period, circulation is back and forth until furnace shell erecting and welding is completed.
The present invention evades the drawbacks of original conventional construction method, and furnace shell is welded by taking self-lifting system, to apply
Worker person provides a safe and reliable operation platform, while solving the problems such as radix saposhnikoviae, rain-proof, installation for welding storage, has
Effect ensure that furnace shell construction quality improves construction efficiency, while be again the installation of next step cooling wall, furnace sealing facility peace
