[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0043] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] The embodiment of the present invention provides a large-scale cylinder structure turning and hoisting device, such as Figure 1-Figure 10 As shown, the large-scale cylinder structure turning and hoisting device is based on two sets of cranes and includes:

[0045] The upper flange assembly 200 includes a connecting ring 210, a limiting rail 220, and four sets of sliding members 230 sliding on the limiting rail 220. In order to facilitate the display of structural features, Figure 2 Only two sets of sliding members 230 are drawn, but there are not only two sets of sliding members 230; the connecting ring 210 is connected to the flange provided at one end of the cylinder structure 100 through a bolt structure;

[0046] The sliding members 230 are grouped in pairs to form a first traction module and a second traction module, and two groups of connecting cables are arranged between the first traction module and the second traction module, and both ends of the connecting cables are connected to the sliding members 230 respectively; a guide assembly 400 is arranged on the connecting cables, and a group of cranes is connected to the guide assembly 400, and the traction force provided by the cranes is dispersed to the four groups of sliding members 230 through the connecting cables, so as to avoid the traction force being concentrated in one place of the cylinder structure 100, causing the cylinder structure 100 to shake during the lifting process;

[0047] The sliding member 230 can slide along the limiting track 220. The two sets of sliding members 230 in the second traction module will be pre-adjusted before traction so that they are away from each other to ensure that the force points are evenly distributed.

[0048] In the horizontal state, the crane applies traction to the cylinder structure 100 on one side of the upper flange assembly 200 to keep it away from the ground; Figure 5 For example, the two groups of sliding members 230 in the first traction module are located at the semi-arc of the upper flange assembly 200 away from the ground, and the two groups of sliding members 230 in the second traction module are located at the semi-arc of the upper flange assembly 200 close to the ground. In the horizontal state, the two groups of sliding members 230 in the first traction module are close to each other before hoisting, and the two groups of traction points of the first traction module are relatively close, and the traction point of the first traction module is closer to the crane than the traction point of the second traction module. The traction points of the second traction module are superimposed with the influence of gravity and need to be far away from each other to provide stability; at this time, the more concentrated the traction points of the first traction module are, the closer they can be to the vertex of the tube structure 100, and cooperate with the traction points of the second traction module to form a structure similar to an equilateral triangle, which is conducive to improving the stability during the traction process;

[0049] When the cylinder structure 100 is pulled to a certain height and presents an inclined state, the two groups of sliding members 230 in the first pulling module begin to move away from each other, so that the two groups of sliding members 230 are dispersed to increase the number of stress points of the cylinder structure 100, and the pulling force can be evenly applied to the cylinder structure 100, thereby improving the stability of the cylinder structure 100 during the hoisting process. In the state of large-angle inclination, the more connection points, the higher the stability; it should be noted that the crane does not work when the sliding member 230 is moving to avoid excessive force on the components and damage;

[0050] A lower flange assembly 300, which is connected to one end of the barrel structure 100 away from the upper flange assembly 200, and includes a connecting plate 310, an outer ring 320, an inner circular plate 330, a connecting seat 340 and a guide slide 350; the outer ring 320 and the inner circular plate 330 are arranged on the end surface of the connecting plate 310, the outer ring 320 and the inner circular plate 330 form an annular track, the guide slide 350 extends into the annular track and slides on the annular track, and the connecting seat 340 is arranged at the center of the connecting plate 310;

[0051] The ends of the traction ropes, i.e. the cables of another group of cranes, are connected to the connection seat 340 after passing through the guide slide 350. During the traction process, the cables pass through the guide slide 350, and the guide slide 350 protects the cables to prevent the cables from contacting the edge of the cylinder structure 100, thereby reducing the wear of the cables during the traction process and increasing the safety during the hoisting process.

[0052] In the present application, the cylinder structure 100 is a common cylindrical component that needs to be connected in the prior art, and flanges are provided at both ends as connecting ends. During the assembly process, the cylinder structure 100 is initially in a horizontal state, and then the upper flange assembly 200 and the lower flange assembly 300 are respectively connected to the flanges at both ends of the cylinder structure 100 by bolt fixing, and the connecting ring 210 and the connecting plate 310 are provided with corresponding screw hole structures; for some flanges with different sizes and diameters, an adapter flange can be used as an intermediate connecting piece for adaptation, for example, a plurality of groups of screw holes of different specifications are provided on the adapter flange, and one end of the adapter flange is connected to the cylinder body and the other end is connected to the cylinder structure 100;

[0053] After the assembly is completed, the two groups of cranes are connected to the upper flange assembly 200 and the lower flange assembly 300 respectively and traction is applied. Usually, the end face of the crane traction cylinder structure 100 connected to one side of the upper flange assembly 200 rises, while the end face of the crane traction cylinder structure 100 connected to one side of the lower flange assembly 300 drops. During the traction process, the upper flange assembly 200 will be transformed from a vertical state to a horizontal state as the cylinder structure 100 deflects away from the ground, and the cylinder structure 100 will also be transformed from a horizontal state to a vertical state in this process; after the vertical state conversion is completed, the lower flange assembly 300 is first removed and then the end face of the cylinder structure 100 facing the ground is aligned with the existing base or cylinder body, and then the crane is lowered to complete the docking connection;

[0054] During this process, the first traction module will transform its state, so that the position of the force point on the traction side of the upper flange assembly 200 changes, gradually transforming from the early equilateral triangle structure to a four-point distribution, pulling open the sliding member 230, and meeting the needs of different lifting processes through form transformation, thereby maximizing the stability of the lifting tube structure 100 during the lifting process;

[0061] The inner track frame 221 is also provided with a lifting ring connection seat, which includes an annular seat 2341, a rotating column 2342 and a connecting ring 2343.

[0062] In this embodiment, the driving mechanism 233 is assembled with reference to the structure of the motor, reducer and brake device in the prior art winch and serves as the power source of the driving wheel 232; the driving mechanism 233 will extend into the cylinder structure 100 during the assembly process to avoid the driving mechanism 233 falling off due to the movement of the connecting cable. Therefore, it is necessary to pay attention to the diameter of the cylinder when selecting the type to avoid the situation where the driving mechanism 233 extends into the cylinder;
