The catalytic flue gas turbine rotor can be freely moved in six directions of front, back, up, down, left and right through the rotor moving folding bracket, the coupling side lifting bracket and the wheel side lifting bracket, so as to complete precise adjustment and positioning, greatly reducing the safety risks in the process of disassembling and assembling the rotor, and safely, stably and quickly disassembling and installing the rotor. The time for the entire catalytic flue gas turbine rotor disassembly or installation process is shortened to one-fourth of the time taken by the original traditional lifting method. There is no need to set a lifting point in the equipment area, and the disassembly and translation adjustment links during maintenance can be safely controlled, ensuring that the entire rotor extraction and installation process is safe, precise and controlled, and avoiding the risks of parts falling damage and personal injury that may be caused by the traditional method of using multiple high and low hand chain hoists to lift obliquely and crookedly.

[0016] Each catalytic flue gas turbine overhaul is completed 3-5 days earlier than traditional operations. Starting work early can save 240,000 yuan in electricity bills per day, a total of about 1 million yuan. In addition, the process throughput is increased by 30%, bringing huge benefits. At the same time, it reduces safety risks, shortens operation time, saves costs, and improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] A method for disassembling and installing a catalytic flue gas turbine rotor includes a disassembly process and an installation process.

[0039] The disassembly process of the flue gas turbine rotor is completed through three stages: raising and translating the flue gas turbine rotor, switching the flue gas turbine rotor bracket and translating and hoisting the flue gas turbine rotor. The flue gas turbine rotor is lifted up and away from the flue gas turbine casing by moving the brackets at both ends of the wheel disc side and the coupling side, and translated to the outside of the flue gas turbine along the track. It is switched to the flue gas turbine rotor folding bracket, translated along the track away from the flue gas turbine casing, and removed.

[0040] The installation process of the flue gas turbine rotor is completed through three stages: hoisting and translation, bracket switching, and translation into position: the smoke turbine rotor is on the smoke turbine rotor folding bracket and translated along the track to penetrate into the smoke turbine casing. After switching to the brackets at both ends, the smoke turbine rotor is translated to the top of the smoke turbine rotor casing and lowered for installation.

[0041] The disassembly process includes the rotor lifting and translation stage, the rotor bracket switching stage and the rotor translation hoisting stage. The specific steps include:

[0042] a) Rotor lifting and translation phase (see Fig.10 and Fig.11 )

[0043] First adjust the wheel disc side lifting shaft bracket 4 ( Figure 4 ) on the height position of the rotor chuck (4-6), install the rotor chuck (4-6) on the wheel disc of the range hood rotor 100, fine-tune the wheel disc side shaft lifting bracket 4 wheel disc bracket height adjustment bolts and nuts 4-1, 4-2, and try the lifting function. Then install the coupling side shaft lifting bracket 3 ( Figure 3 ), note that the shaft lifting coupling carrier 3-8 should be installed between the thrust plate and the coupling (the position of the main thrust pad), and then operate the wheel side shaft lifting bracket 4 ( Figure 4 ) and coupling side shaft lifting bracket 3 ( Figure 3), so that the range hood rotor 100 slowly rises to the designed height (235mm), and the height ensures that the range hood rotor 100 can pass through the bearing housing 300 and the range hood housing 200. After the height is met, finally raise the coupling side shaft lifting bracket 3 ( Figure 3 )'s coupling bracket lower support beam 3-5 is installed in place, and the support adjustment safety bolt 3-6 is rotated into place, supported on the coupling bracket lower support beam 3-5, and finally the range hood rotor 100 is slowly pushed out to the wheel disc side about 1.5 meters manually. If the height, left and right positions are not suitable during the movement, the height and left and right positions of the front and rear brackets can be adjusted.

[0044] b) Switching rotor support stage (see Fig.12 , Fig.13 and Fig.14 )

[0045] Move the folded rotor to the folding bracket 2 ( Figure 2 ) Lift the shaft support 4 from the wheel disc side ( Figure 4 ) through the bottom of the pedal 4-10, and then move the rotor to fold the bracket 1 ( Figure 2 ) is adjusted to the open state, and the two sides of the rotor are lifted up stably and reliably by adjusting the wheel disc side height adjustment nut 1-6, the bracket beam positioning support nut 1-7, the wheel disc side left and right adjustment support beam 1-5 and the coupling side height adjustment bolt 1-2, the coupling side left and right adjustment support beam positioning support nut 1-3, and the coupling side left and right adjustment support beam 1-1. Then, lift the wheel disc side shaft lifting bracket 4( Figure 4 ) and coupling side shaft lifting bracket 3 ( Figure 3 ) Remove. Note that the center of gravity of the flue gas turbine must be kept between the two support beams of the flue gas turbine rotor moving folding support 1 to ensure the safety and stability of the tooling.

[0046] c) Rotor translation and lifting stage (see Fig.15 , Fig.16 and Fig.17 )

[0047] Push the rotor moving folding bracket 1 and slowly move it 2.5 meters to the position where the bridge crane can directly lift it. Then use the bridge crane's large hook to directly lift the range hood rotor 100 onto the special bracket for rotor transportation.

[0048] The installation process includes the hoisting and translation stage, the bracket switching stage and the translation into place stage. The specific steps include:

[0049] a) Lifting and translation stage (see Fig.18 , Fig.19 , Fig. 20 and Fig.21 )

[0050] First, move the rotor to fold the bracket 1 ( Figure 1 ) to the working state, and then use the bridge crane hook (the allowable lifting weight is five times the weight of the rotor) to lift the range hood rotor 100 to the rotor moving folding bracket 1 ( Figure 1 ), and then adjust the height adjustment nut 1-6 on the disc side, the bracket beam positioning support nut 1-7, the left and right adjustment support beam 1-5 on the disc side and the height adjustment bolt 1-2 on the coupling side, the left and right adjustment support beam positioning support nut 1-3 on the coupling side, and the left and right adjustment support beam 1-1 on the coupling side to ensure that the range hood rotor 100 cannot touch the components in the range hood housing 200 and the bearing box 300 during movement, and pass the range hood rotor 100 into the range hood housing 200 about 1.5 meters.

[0051] b)Stent switching phase (see Fig. 22 and Fig.23 )
