[0050] S1. Calculate the maximum load of the fixing frame 2 at the top of the absorption tower 1 and select a lifting device so that the sum of the mass of the lifting device and the maximum mass of the items that can be hoisted by the lifting device is less than the maximum load of the fixing frame 2.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, in step S1, the fixing frame 2 includes a plurality of fixing beams 21, the mounting frame 3 is connected to the fixing beams 21, and the mid-span load of the fixing beams 21 is calculated and used as the maximum load of the fixing frame 2. The fixing beams 21 are used to support the lifting equipment, and the mid-span load of the fixing beams 21 is greater than the sum of the mass of the lifting equipment and the maximum mass of the objects that can be hoisted by the lifting equipment, so as to prevent the fixing beams 21 from breaking.

[0052] Specifically, the top of the absorption tower 1 includes a center ring 11 located at the center of the absorption tower 1 and a top plate 12 located on the periphery of the center ring 11, and the upper surface of the top plate 12 extends downward in a direction away from the center of the absorption tower 1. For example, the upper surface of the top plate 12 is annular, and at least a portion of the upper surface of the top plate 12 is a conical surface.

[0053] In step S1, a fixing frame 2 is arranged on the top plate 12, and the fixing frame 2 includes a plurality of fixing beams 21 and a plurality of reinforcing ring ribs 22, and the plurality of fixing beams 21 are fixed on the top plate 12 along the circumferential direction. The length direction of each fixing beam 21 in the horizontal direction is consistent with the radial direction of the absorption tower 1, and the first end of each fixing beam 21 is connected to the center ring 11, and the plurality of fixing beams 21 are arranged on the peripheral side of the center ring 11 along the circumferential direction, and the second end of the fixing beam 21 is adjacent to the outer edge of the top plate 12. The reinforcing ring ribs 22 are connected to the fixing beams 21 and the top plate 12, and two fixing beams 21 adjacent to each other in the circumferential direction are connected by the reinforcing ring ribs 22. The fixing beams 21 are arranged at an angle to match the shape of the top plate 12, and the plurality of fixing beams 21 and the plurality of reinforcing ring ribs 22 cooperate to improve the structural strength of the fixing frame 2.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, a plurality of reinforcing ring ribs 22 form a plurality of reinforcing rings arranged at intervals on the top plate 12, and the plurality of reinforcing rings are arranged around the circumference of the center ring 11 in a direction away from the center of the absorption tower 1. Specifically, the reinforcing ring ribs 22 are welded to the top plate 12 and the corresponding fixing beams 21. The plurality of reinforcing ring ribs 22 are welded to each other in the circumferential direction in sequence to form reinforcing rings, and the plurality of reinforcing rings cooperate with the plurality of fixing beams 21 to improve the structural strength of the fixing frame 2.

[0055] In some embodiments, the fixing frame 2 includes a reinforcement ring 23, the inner side of the reinforcement ring 23 is connected to the outer peripheral side of the absorption tower 1, and the top of the reinforcement ring 23 is connected to the second end of the fixing beam 21 through a reinforcing plate, thereby further improving the structural strength of the fixing frame 2.

[0056] In some embodiments, in step S1, after the installation fence is set at the outer edge of the top of the absorption tower 1, at least part of the fixing frame 2 is set at the top of the absorption tower 1, and a maintenance platform adjacent to the installation frame 3 and located below the lifting equipment is set at the top of the absorption tower 1. Specifically, the top of the absorption tower 1 is provided with a maintenance platform adjacent to the installation frame 3 and located below the lifting equipment, so as to facilitate the maintenance of the installed lifting equipment. For example, a steel pipe is used to make the installation fence, and the installation fence is 1.2 meters high and 6 meters long. A maintenance platform with a height of 1.5 meters is set below the track of the lifting equipment, and a protective fence is well made.

[0057] In some embodiments, in step S1, the sum of the mass of the lifting equipment and the maximum mass of the object that can be lifted by the lifting equipment is less than 5 tons. For example, the sum of the mass of the lifting equipment and the maximum mass of the object that can be lifted by the lifting equipment is 2 tons or 3 tons.

[0058] like Figures 1 to 5As shown, S2, a mounting frame 3 is arranged on the fixing frame 2, and the upper surface of the mounting frame 3 is a horizontal plane. The mounting frame 3 is fixed on the fixing frame 2 and is adjacent to the outer edge of the top plate 12. Specifically, the structural strength of the outer edge of the fixing frame 2 adjacent to the top plate 12 is high. In step S2, the mounting frame 3 adjacent to the top outer edge of the absorption tower 1 is arranged on the fixing frame 2, so that the absorption tower 1 is not easily crushed.

[0059] Specifically, the mounting frame 3 is adjacent to the top outer edge of the absorption tower 1, and the mounting frame 3 is connected to the fixed beam 21 and is adjacent to the second end of the fixed beam 21, that is, the mounting frame 3 is connected to the end of the fixed beam 21 adjacent to the absorption tower 1, and the end load of the fixed beam 21 is large, so that the fixed beam 21 can easily support the mounting frame 3.

[0060] In some embodiments, the plurality of fixing beams 21 include a first fixing beam 211. The mounting frame 3 includes a first mounting rod 31, a second mounting rod 32 and a third mounting rod 33 connected to the top plate 12.

[0061] The first mounting rod 31 is located on a side of the outer edge of the second mounting rod 32 adjacent to the top plate 12 , and the top surfaces of the first mounting rod 31 and the second mounting rod 32 are both horizontal planes. Specifically, the first mounting rod 31 and the second mounting rod 32 are spaced apart in the radial direction of the absorption tower 1 .

[0062] The extension direction of the third mounting rod 33 in the horizontal direction intersects with the extension direction of each of the first mounting rod 31, the second mounting rod 32 and the first fixed beam 211 in the horizontal direction. One end of the third mounting rod 33 is adjacent to the outer edge of the top plate 12, and the other end of the third mounting rod 33 is connected to the first fixed beam 211 (middle position), that is, the third mounting rod 33 is inclined relative to the first fixed beam 211. Both ends of each of the first mounting rod 31 and the second mounting rod 32 are connected to the first fixed beam 211 and the third mounting rod 33, respectively, and the column foundation 4 is fixed to at least one of the first mounting rod 31, the second mounting rod 32 and the third mounting rod 33. That is, the first mounting rod 31, the second mounting rod 32 and the first fixed beam 211 are connected to the top plate 12 and the first fixed beam 211 to form the mounting frame 3. For example, there are multiple first mounting rods 31 and second mounting rods 32.

[0063] S3, fixing the column foundation 4 of the lifting equipment on the upper surface of the mounting frame 3. Specifically, the column foundation 4 is fixed on the mounting frame 3, and the lifting equipment is fixed on the column foundation 4. For example, the thickness of the column foundation 4 is greater than or equal to 20 mm, the column foundation 4 is welded to the mounting frame 3, and a plurality of screw holes are provided on the column foundation 4.

[0064] S4, using a sling to hoist the lifting equipment to the top of the absorption tower 1 and connect it to the column foundation 4. Specifically, the lifting equipment is an electric wire rope hoist 5. In step S4, the column 51 of the electric wire rope hoist 5 is first hoisted and fixed on the column foundation 4, and then the crossbeam 53 with the electric hoist 52 installed is hoisted and fixed on the column 51. For example, the crossbeam 53 is fixed using a special fixing nut, and after the hoisting is completed, the electric wire rope hoist 5 is fully anti-corrosion treated.

[0065] In a specific embodiment, the deadweight of the lifting equipment is 1500kg, the lifting weight (the maximum weight of the object that the lifting equipment can lift) is 2000kg, and the sum of the weight of the lifting equipment and the maximum weight of the object that the lifting equipment can lift is 3500kg. The fixed beam 21 is an H-shaped steel, and the steel section modulus Wx of the fixed beam 21 is 868.14cm 3 , the bending stress σ of the fixed beam 21 is 1400kg / cm 2 , the span L of the fixed beam 21 is 8.413 meters.

[0066] If the load of the fixed beam 21 acts at the mid-span, the maximum bending moment of the fixed beam 21 at the load action point is: M = Wx [σ] = 868.14cm * 0.014 = 12.15t / m. When L = 8.413 meters, M = PL / 4; then 12.15 = P * 8.413 / 4 = 2.1P, the mid-span load of the fixed beam 21 P = 12.15 / 2.1 = 5.78t, that is, the mid-span load of the fixed beam 21 can bear a weight of 5.78t, and it is a mid-span load. The sum of the mass of the lifting equipment and the maximum mass of the items that can be hoisted by the lifting equipment is less than the mid-span load of the fixed beam 21, that is, the mid-span load of the fixed beam 21 and the selection of the lifting equipment meet the requirements.
