[0022] The following describes exemplary embodiments of the present utility model with reference to the accompanying drawings. Various details of the embodiments of the present utility model are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present utility model. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0023] At least one embodiment of the present utility model provides an overall tensioning tooling after assembling multiple barrel sections. To solve the problem of the stability such as sliding between barrel sections and overall tipping during the movement and hoisting of multiple circular barrel sections after assembly, after the assembly is completed, it is necessary to use a tooling to fix it between the top and the bottom. As Figure 1 shown, the overall tensioning tooling after assembling multiple barrel sections may include a bottom lifting lug 1, a tensioning rope hook 2, a tensioning rope 3, a top extended bolt 4, an adjusting nut 5, a top hollow ring 6, and a bottom hollow ring 7. In the embodiment, the bottom lifting lug 1 is connected to the tensioning rope hook 2, and the other end of the tensioning rope hook 2 is connected to the tensioning rope 3. The bottom lifting lug 1 is fixed on the bottom hollow ring 6, and the bottom hollow ring 7 is placed at the bottom of multiple barrels; the other end of the tensioning rope 3 is connected to the top extended bolt 4 and passes through the top hollow ring 6, and an adjusting nut 5 is arranged on the top hollow ring 6.

[0024] Exemplarily, the bottom lifting lug 1 is fixed on the bottom hollow ring 7 to form an integral body. The bottom hollow ring 7 is placed at the bottom of multiple barrels, and the outermost side of the bottom hollow ring 7 contacts the multiple barrels. The tensioning rope hook 2 connects the tensioning rope 3. The upper part of the tensioning rope 3 is connected to the top extended bolt 4 and passes through the round hole of the top hollow ring 6. The tensioning rope 3 is tightened by using the adjusting nut 5. The outermost side of the top hollow ring 6 presses against the top of the multiple barrels, and the multiple barrels are tightened by the tightened tensioning rope 3 to prevent tipping.

[0025] In some preferred embodiments, the top hollow ring 6 and the bottom hollow ring 7 of the overall tensioning tooling after the assembly of multiple barrel sections are respectively installed at opposite ends of the multiple barrel sections, and are connected by a tensioning rope 3 in the middle. Further, the other end of the tensioning rope 3 is also provided with a hook, and is connected to the lifting ring at one end of the top extension bolt 4. The tensioning rope 3 itself has a certain strength of tension.

[0026] In a preferred embodiment, in order to ensure that the top extension bolt has the ability to adjust, the length of the tensioning rope 3 is less than the distance from the bottom lifting lug 1 to the top hollow ring 6, and the sum of the lengths of the tensioning rope 3 and the top extension bolt 4 is greater than the distance from the bottom lifting lug 1 to the top hollow ring 6.

[0027] As some other embodiments of the present invention, as Figure 1 , 2 shown, the overall tensioning tooling after the assembly of the multiple barrel sections includes a plurality of bottom lifting lugs 1 uniformly arranged around the center of the bottom hollow ring 7 (for example: 4 bottom lifting lugs 1 are uniformly arranged around the center). A plurality of top extension bolts 4 perpendicular and symmetrical to the bottom lifting lugs 1 are provided on the top hollow ring 6. The bottom hollow ring 7 is fixed to one end of the multiple barrel sections and is opposite to the main body of the top hollow ring 6 at the other end. The tensioning rope 3 connects the symmetrically arranged upper and lower lifting lugs (the bottom lifting lugs 1 and the lifting lugs on the top extension bolts 4), and the tensioning force of the tensioning rope 3 is changed by changing the length of the extended lifting lugs.

[0028] It should be noted that the bottom lifting lug 1 and the circular hole where the top extension bolt 4 is located maintain concentricity in the vertical direction. In addition, the form of the hook 2 of the tensioning rope is open or closed, and is fixed to the bottom hollow ring 7 by punching or welding evenly. Its material is cast iron, carbon steel series or stainless steel series.

[0029] As still some other embodiments of the present invention, as Figure 1 shown, the overall tensioning tooling after the assembly of the multiple barrel sections includes that the top hollow ring 6 and the bottom hollow ring 7 are respectively designed as steel rings with a preset width (as Figure 5 shown) or are designed to include a steel ring with a preset width and a cross on the middle of the steel ring (as Figure 4 shown).

[0030] In a further embodiment, the top extension bolt 4 has a thread with a certain length, passes through the steel ring or the cross, and is fixed with an adjusting nut 5. By tightening or loosening the adjusting nut 5, the up and down change of the long screw is realized to tighten or loosen the tensioning rope.

[0031] In a still further embodiment, the materials of the top hollow ring 6 and the bottom hollow ring 7 are cast iron, carbon steel series or stainless steel series.

[0032] As other embodiments of the present utility model, the top extension bolt 4 is fixed to the top hollow ring 6 in an inverted installation manner, and the material is cast iron, carbon steel series or stainless steel series.

[0033] Meanwhile, according to the dimensions of the cylinder sections that need to be assembled, the present utility model can fabricate a bottom hollow ring 7 that conforms to the actual situation at the bottom of the cylinder. Four bottom lifting lugs 1 are evenly arranged at a certain distance from the center of the bottom hollow ring 7 to the surrounding, and are placed at the bottom of the cylinder section before the assembly of multiple cylinder sections. The top hollow ring 6 is fabricated according to the actual situation at the top. Four top round holes are evenly arranged at a certain distance from the top hollow ring 6 to the surrounding. After the multiple cylinder sections are assembled, it is placed at the top. The distance between the bottom lifting lug 1 and the center of the bottom hollow ring 7 should be equal to the distance between the top round hole and the center of the top hollow ring 6, that is, they should be concentric in the vertical direction after assembly. According to the distance from the hook of the bottom hollow ring 7 to the top hollow ring 6, four tension ropes 3 with hooks on both sides of appropriate length are fabricated. A certain length of the top extension bolt 4 is passed through the top round hole from bottom to top. After passing through, the adjusting nut 5 is tightened. The hooks on both sides of the tension rope 3 are respectively connected to the bottom lifting lug 1 and the top extension bolt 4. The bottom hollow ring 7 serves as the bottom force-bearing point of the tension rope 3, and the top hollow ring 6 serves as the top force-bearing point of the tension rope 3. By gradually tightening the adjusting nut 5, the tension rope 3 is tightened during the upward movement of the top extension bolt 4 (as Figure 3 shown).

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] The above specific embodiments do not constitute a limitation to the protection scope of the present utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present utility model should be included within the protection scope of the present utility model.
