[0042] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0043] It should be noted that, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed", "set" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located on the other element, or there may be one or more intermediate elements. The terms "first", "second", "third", etc. are only for the convenience of describing the present technical solution, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0044] like Figure 1 and Figure 2As shown, a tower rollover auxiliary device according to an embodiment of the present invention includes a first support base 1 , a second support base 2 , a third support base 3 , a mounting base 4 and a winch 5 . Figure 2 In order to clearly illustrate the structure of the tower rollover auxiliary device, the physical structure of the tower 6 is hidden, and the outline of the tower 6 is outlined with a dotted line. When the tower rollover auxiliary device is in a working state, the first support seat 1, the second support seat 2 and the third support seat 3 are arranged at intervals from each other, wherein the second support seat 2 is located between the first support seat 1 and the third support seat 3. The first support seat 1, the second support seat 2 and the third support seat 3 are arranged in a straight line, that is, the three are arranged to extend along the same straight line.

[0045] The third support seat 3 is used to support the small diameter end 62 of the tower 6. The mounting seat 4 is used to fix the large diameter end 61 of the tower 6. Specifically, the diameter of the tower 6 is usually gradually changed along its length direction, so the tower 6 has a large diameter end 61 and a small diameter end 62 relative to each other. The diameter of the large diameter end 61 is larger than the diameter of the small diameter end 62. When the tower 6 is in a horizontal state, its large diameter end 61 can be fixed by the mounting seat 4, and its small diameter end 62 can be supported and fixed by the third support seat 3. The third support seat 3 and the mounting seat 4 play a two-point support role for the tower 6 in a horizontal state.

[0046] The mounting base 4 can be flipped between a first position and a second position. The flipping of the tower 6 is mainly driven by the flipping of the mounting base 4. The mounting base 4 includes a first end 41 and a second end 42 opposite to each other. The direction in which the mounting base 4 extends from the first end 41 to the second end 42 is defined as the length direction of the mounting base 4.

[0047] like Figure 1 and Figure 2 As shown, in the first position, the first end 41 of the mounting base 4 is supported on the second support base 2, and the mounting base 4 is separated from the first support base 1. The mounting base 4 is in an upright state, that is, the length direction of the mounting base 4 is relatively perpendicular to the ground 71. Correspondingly, the tower 6 is in a horizontal state (horizontally placed), that is, the length direction of the tower 6 is relatively parallel to the ground 71.

[0048] like Fig.14 As shown, in the second position, the first end 41 of the mounting base 4 is still supported on the second support base 2, and the position near the second end 42 of the mounting base 4 is supported on the first support base 1. The mounting base 4 is in a horizontally placed state, and the length direction of the mounting base 4 is relatively parallel to the ground 71. Correspondingly, the tower 6 is in an upright state (horizontally placed state), that is, the length direction of the tower 6 is relatively perpendicular to the ground 71. At this point, the tower 6 has completed its flipping.

[0049] The hoist 5 is arranged on the first support seat 1 and connected to the mounting seat 4 through a sling. Specifically, the sling can be a wire rope or a chain. Fig.13 As shown, between the first position and the second position, the mounting seat 4 will also pass through the initial position. In the initial position, the mounting seat 4 itself is balanced and maintained in an inclined state. The mounting seat 4 can first flip from the initial position to the first position, connect with the tower 6 at the first position, and then flip back to the initial position from the first position. The winch 5 is mainly used to drive the mounting seat 4 to flip from the initial position to the second position. Specifically, the mounting seat 4 first relies on the deadweight pressure of the tower 6 to reach the initial position; then, the mounting seat 4 relies on the driving force of the winch 5 to retract the sling to slowly and steadily reach the second position from the initial position. Thus, the winch 5 is connected to the mounting seat 4 through the sling, providing a part of the driving force and stabilizing force for the flipping of the mounting seat 4, so that the flipping process of the mounting seat 4 is smooth, so that the mounting seat 4 drives the tower 6 thereon to flip smoothly to the second position, and this mechanism will not introduce collisions and mechanism wear.

[0050] Thus, through the mutual cooperation and coordinated work of the first support seat 1, the second support seat 2, the third support seat 3, the mounting seat 4 and the hoist 5, the tower 6 can be safely and smoothly flipped to an upright state. The first support seat 1, the second support seat 2 and the third support seat 3 can be transported to the site independently, and then placed on the ground 71 at intervals. Further, the first support seat 1, the second support seat 2, the third support seat 3, the mounting seat 4 and the hoist 5 are independent objects. For example, the mounting seat 4 and the second support seat 2 can be detachably connected; the hoist 5 can be detachably arranged on the first support seat 1. Thus, the first support seat 1, the second support seat 2, the third support seat 3, the mounting seat 4 and the hoist 5 can be transported to the site independently for installation, which is further more convenient for transportation and installation.

[0051] In summary, the tower turning auxiliary device of the present invention enables the tower 6 to be turned safely and smoothly to an upright state through the mutual cooperation and coordinated work of the first support seat 1, the second support seat 2, the third support seat 3, the mounting seat 4 and the winch 5. In addition, since the first support seat 1, the second support seat 2 and the third support seat 3 are arranged at intervals from each other when the tower turning auxiliary device is in the working state, the tower turning auxiliary device of the present invention adopts a modular design, and the first support seat 1, the second support seat 2 and the third support seat 3 can be transported to the site independently and then placed on the ground 71 at intervals from each other, with a simple structure, a small footprint and easy transportation. The winch 5 is connected to the mounting seat 4 through a sling, and provides a part of the driving force for the turning of the mounting seat 4, so that the turning process of the mounting seat 4 is smooth, so that the mounting seat 4 drives the tower 6 thereon to turn smoothly and accurately to the second position, and the tower 6 will not shake.

[0052] The "tower 6" mentioned herein may refer to the entire tower 6 or a part (tower segment) of the tower 6. Therefore, the tower flip auxiliary device of the present invention can be used for flipping the tower 6 or flipping a tower segment.

[0053] like Figures 1 to 4 As shown, in some embodiments, the mounting base 4 includes a main body 40, a first rotating shaft 431 and a second rotating shaft 432 arranged on the main body 40. The main body 40 is used to fix the large diameter end 61 of the tower 6, the first rotating shaft 431 is adapted to the first support seat 1, and the second rotating shaft 432 is adapted to the second support seat 2. In the process of the mounting base 4 moving from the first position to the initial position, the second rotating shaft 432 is always in contact with the second support seat 2 to obtain a stable supporting force, and the second rotating shaft 432 rotates relative to the second support seat 2, thereby driving the main body 40 to rotate, and then driving the tower 6 to flip. Similarly, in the process of the mounting base 4 moving from the initial position to the second position, the first rotating shaft 431 is always in contact with the first support seat 1 to obtain a stable supporting force, and the first rotating shaft 431 rotates relative to the first support seat 1, thereby driving the main body 40 to rotate, and then driving the tower 6 to flip to an upright state.

[0054] Furthermore, if Figures 1 to 4 As shown, in some embodiments, the main body 40 includes two longitudinal beams 401 arranged in parallel and spaced apart, and a cross beam 402 connected between the two longitudinal beams 401 (see Figure 6 ). The number of the first rotating shafts 431 is two, and the number of the second rotating shafts 432 is also two. In the first position, the two first rotating shafts 431 are respectively located on the upper side of the two longitudinal beams 401 (positions near the second end 42 of the mounting seat 4), and the two second rotating shafts 432 are respectively located on the lower side of the two longitudinal beams 401 (corresponding to the first end 41 of the mounting seat 4). Of course, in other embodiments, the number of the first rotating shaft 431 and the second rotating shaft 432 can also be one, and the main body 40 can be a continuous and complete whole. In the first position, the first rotating shaft 431 and the second rotating shaft 432 are respectively arranged on the upper and lower sides of the main body 40.

[0055] like Figure 4As shown, in some embodiments, the mounting seat 4 further includes a first stopper 441 and a first stopper shaft 442, and the first stopper 441 is arranged on the longitudinal beam 401 of the main body 40. In the first position, the first stopper shaft 442 is inserted between the first stopper 441 and the second support seat 2 to fix the mounting seat 4 on the second support seat 2. Specifically, a fixing plate 443 is provided on the second support seat 2 for inserting the first stopper shaft 442. The first stopper shaft 442 is inserted between the first stopper 441 and the fixing plate 443 on the second support seat 2 to fix the mounting seat 4 on the second support seat 2. Thus, the mounting seat 4 is detachably connected to the second support seat 2 through the first stopper 441 and the first stopper shaft 442. When the first stopper shaft 442 is inserted between the first stopper 441 and the second support seat 2, the relative displacement between the mounting seat 4 and the second support seat 2 is constrained. When necessary, the first limiting shaft 442 can be removed, and relative displacement can occur between the mounting seat 4 and the second supporting seat 2, so that the mounting seat 4 and the second supporting seat 2 become separable.

[0056] like Figure 4 As shown, in some embodiments, the mounting base 4 further includes a tower support assembly disposed on the main body 40, and the tower support assembly is provided with at least one arc surface adapted to the outer peripheral surface of the large diameter end 61 of the tower 6. The tower support assembly contacts the outer peripheral surface of the large diameter end 61 of the tower 6 through the arc surface, thereby providing stable support for the tower 6.

[0057] Furthermore, if Figure 4 and Figure 5 As shown, in some embodiments, the tower support assembly includes a fixed member 451, a rotating member 452 and a third rotating shaft 453 arranged on the longitudinal beam 401 of the main body 40. The rotating member 452 is arranged above the fixed member 451. It should be noted that the "above" mentioned here means that when the tower flip auxiliary device is in the working state (that is, placed on the ground 71 and assembled), the rotating member 452 is arranged above the fixed member 451. The third rotating shaft 453 passes through the rotating member 452 to provide a rotating support point for the rotation of the rotating member 452. The rotating member 452 is provided with a curved surface that matches the outer peripheral surface of the large diameter end 61 of the tower 6 on the side facing away from the fixed member 451, and the outer peripheral surface of the large diameter end 61 of the tower 6 can contact the curved surface. The rotating member 452 is provided with a plane on the side facing the fixed member 451. The fixed member 451 is provided with a first inclined surface 4511 and a second inclined surface 4512 on the side facing the rotating member 452.

[0058] The rotating member 452 can rotate between a third position and a fourth position with the third rotating shaft 453 as the rotation center. Figure 5The two positions of the rotating member 452 are indicated by a solid line outline and a dotted line outline. For the convenience of explanation and understanding, it is predefined that the second inclined surface 4512 is closer to the central axis of the tower 6 than the first inclined surface 4511, that is, the second inclined surface 4512 is closer to the central axis of the tower 6. Figure 5 On the middle right side, the first slope 4511 is Figure 5 Left of center. See Figure 5 As shown in the solid line outline in FIG. 4 , in the third position, a portion of the plane is in contact with the first inclined surface 4511, and another portion of the plane is spaced apart from the second inclined surface 4512. Before contacting the tower 6, the rotating member 452 is naturally maintained in the third position. Figure 5 As shown in the dotted outline in the figure, after the tower 6 contacts the arc surface on the rotating member 452, the rotating member 452 rotates due to the gravity extrusion of the large diameter end 61 of the tower 6, and tends to rotate in the direction close to the central axis of the tower 6. Until the rotating member 452 rotates to the fourth position, a part of the plane fits with the second inclined surface 4512, and another part of the plane forms a gap with the first inclined surface 4511. Therefore, when the tower 6 is placed on the arc surface on the rotating member 452, the rotating member 452 is pressed to rotate between the third position and the fourth position, and can adaptively reach a balanced position. Since the fixed member 451, the rotating member 452 and the third rotating shaft 453 cooperate to achieve the effect of adaptive tower 6 gravity, such a design can meet the support requirements of towers 6 of different sizes and expand the application range of the tower flip auxiliary device.

[0059] Furthermore, if Figure 4 As shown, in some embodiments, the tower support assembly further includes a support base 454 disposed on the longitudinal beam 401 of the main body 40. The support base 454 is located on one side of the rotating member 452 close to the central axis of the tower 6 (refer to Figure 4 (right side in the middle). When the tower 6 is placed on the tower support assembly, the support base 454 is located directly below the tower 6. The support base 454 is also provided with an arc surface that matches the outer peripheral surface of the tower 6. As a result, the outer peripheral surface of the tower 6 can contact the arc surface on the rotating member 452 and the arc surface on the support base 454 respectively to obtain stable and reliable support. Furthermore, a plurality of gaskets 70 can be provided on the support base 454. The gaskets 70 can be made of nylon material. The gaskets 70 contact the outer peripheral surface of the tower 6, which can increase the friction between the support base 454 and the tower 6, and provide more stable support for the tower 6.

[0060] like Figure 3 and Figure 4As shown, in some embodiments, the mounting base 4 also includes a tower limiting assembly, and the tower limiting assembly includes a second limiting member 461 and a third limiting member 462. The second limiting member 461 can move vertically relative to the main body 40 (move along the length direction of the mounting base 4) to a preset position. When in the preset position, the second limiting member 461 abuts against the inner circumference of the large diameter end 61 of the tower 6. The third limiting member 462 is arranged on the longitudinal beam 401 of the main body 40 and is connected to the second limiting member 461, and is used to fix the second limiting member 461 in a preset position. Thus, through the coordinated cooperation of the second limiting member 461 and the third limiting member 462, the second limiting member 461 can be vertically fixed at any position to adapt to towers 6 of different thicknesses. Such a design can meet the limiting requirements of thicknesses of different sizes and expand the application range of the tower flip auxiliary device.

[0061] like Figure 4 In the illustrated embodiment, the second stopper 461 includes an abutting portion 4610 and a stopper 4611 connected as one body. The abutting portion 4610 is generally L-shaped, and one end thereof away from the stopper 4611 can abut against the inner circumference of the tower 6. The stopper 4611 is provided with a first through hole. The third stopper 462 includes a positioning plate 4620 and a second stopper shaft 4621. The positioning plate 4620 is provided on the main body 40, and a plurality of second through holes arranged vertically at intervals are provided on the positioning plate 4620. The stopper 4611 moves vertically up and down, and its first through hole can be aligned with any second through hole on the positioning plate 4620. When the abutting portion 4610 reaches the preset position, the first through hole on the stopper 4611 is aligned with the nearest second through hole, and the second stopper shaft 4621 is passed through the first through hole and the second through hole, so that the second stopper 461 can be fixed at the preset position. Of course, in some other embodiments, the second limiting member 461 and the third limiting member 462 may also be other structural forms, as long as the second limiting member 461 can be fixed at a preset position, and the present invention is not limited to this.

[0062] like Figure 6 As shown, in some embodiments, the main body 40 of the mounting seat 4 is provided with a first lifting lug 403 and a second lifting lug 404, the hoist 5 is connected to the first lifting lug 403 through a sling, and the second lifting lug 404 is used to connect a lifting device (not shown). Specifically, the first lifting lug 403 is arranged on a side of the main body 40 close to the first support seat 1, and the second lifting lug 404 is arranged on a side of the main body 40 close to the third support seat 3. The first lifting lug 403 and the second lifting lug 404 can be arranged on the crossbeam 402 of the main body 40.

[0063] like Figure 7As shown, in some embodiments, the first support seat 1 is provided with a first groove 10 and a pad 11. The first rotating shaft 431 of the mounting seat 4 is matched with the first groove 10. When in the second position, the first rotating shaft 431 is supported in the first groove 10, and the main body 40 is fitted with the pad 11. In addition, when the mounting seat 4 is flipped from the initial position to the second position, the first rotating shaft 431 can keep rolling in the first groove 10, thereby realizing the flipping action of the mounting seat 4. The number of the first grooves 10 is matched with the number of the first rotating shafts 431.

[0064] like Figure 7 As shown, in some embodiments, the first support seat 1 includes a first base 13 and two first support beams 14, the two first support beams 14 are arranged at intervals, and the first base 13 spans and is detachably connected to the two first support beams 14. The first groove 10 and the pad 11 are both arranged on the first base 13. That is, the first support seat 1 adopts a modular design, and the first base 13 and the two first support beams 14 can be transported and assembled separately. In this way, the floor space can be further reduced and transportation can be facilitated. Further, as Figure 7 In the illustrated embodiment, the hoist 5 is disposed on one of the first support beams 14. There are two first bases 13, which are spaced apart from each other. The hoist 5 is located in the space between the two first bases 13.

[0065] like Figure 8 As shown, in some embodiments, the second support seat 2 is provided with a second groove 20 and a guide groove 21, and the second shaft 432 is adapted to the second groove 20, and the second shaft 432 is also slidably matched with the guide groove 21. When the mounting seat 4 is between the first position and the initial position, the second shaft 432 is always supported in the second groove 20, and the second shaft 432 can keep rolling in the second groove 20, thereby realizing the flipping action of the mounting seat 4. Fig.13 and Fig.14 As shown, between the initial position and the second position, the mounting seat 4 uses the first rotating shaft 431 as a fulcrum to perform a lever movement, and its first end 41 tilts upward and the second end 42 moves downward. Therefore, in the process from the initial position to the second position, the second rotating shaft 432 will leave the second groove 20. The length direction of the guide groove 21 is roughly extended vertically, and the second rotating shaft 432 slides upward along the guide groove 21, thereby realizing a smooth flipping action of the mounting seat 4. Therefore, the guide groove 21 plays a role in constraining and guiding the first end 41 of the mounting seat 4 in the process of the mounting seat 4 flipping from the initial position to the second position, and plays an important role in the smooth flipping of the mounting seat 4 in the later process. The setting of the guide groove 21 can improve the accuracy of the flipping of the tower 6 and avoid shaking of the tower 6 during the flipping process.

[0066] like Figure 8As shown, in some embodiments, the second support seat 2 includes a second base 22 and two second support beams 23, the two second support beams 23 are arranged at intervals, and the second base 22 spans and is detachably connected to the two second support beams 23. The second groove 20 and the guide groove 21 are both arranged on the second base 22. That is, the second support seat 2 adopts a modular design, and the second base 22 and the two second support beams 23 can be transported and assembled separately. In this way, the floor space can be further reduced and transportation is convenient.

[0067] like Fig. 9 As shown, in some embodiments, the third support seat 3 includes a plurality of vertical plates 31 arranged at intervals, a bottom plate 32 and an arc plate 33. Each vertical plate 31 is connected between the bottom plate 32 and the arc plate 33. The arc plate 33 is adapted to and in contact with the outer peripheral surface of the small diameter end 62 of the tower 6 to provide stable and reliable support for the small diameter end 62 of the tower 6. Further, a plurality of gaskets 70 may be provided on the arc plate 33, and the gaskets 70 may be made of nylon material. The gaskets 70 are in contact with the outer peripheral surface of the tower 6, which can increase the friction between the arc plate 33 and the tower 6, and provide more stable support for the tower 6.

[0068] Accordingly, the present invention also provides a tower turning method, which can be implemented by using any of the tower turning auxiliary devices in the above embodiments. Figures 10 to 14 In some embodiments, the tower turning method includes the following steps:

[0069] S1, place the first support base 1, the second support base 2 and the third support base 3 on the ground 71 at intervals, and place the second support base 2 between the first support base 1 and the third support base 3. Fig.10 As shown, the mounting seat 4 is set in the initial position. In the initial position, the mounting seat 4 is supported on the second support seat 2 and the first support seat 1 at the same time, and the mounting seat 4 is in a state of being inclined relative to the ground 71. That is, an acute angle (about 8°) is formed between the length direction of the mounting seat 4 and the ground 71. With the first rotating shaft 431 as the fulcrum, the mounting seat 4 and the first support seat 1 together form a lever structure. At the same time, the winch 5 is set on the first support seat 1 and the winch 5 is connected to the first lifting lug 403 on the mounting seat 4 through a sling.

[0070] S2, such as Fig.11As shown, the mounting seat 4 is flipped to the first position so that the mounting seat 4 is relatively perpendicular to the ground 71. That is, the length direction of the mounting seat 4 is perpendicular to the ground 71. During the flipping process of the mounting seat 4, the sling of the winch 5 is rolled and extended accordingly. Specifically, the hook of the lifting device is connected to the second lifting ear 404 on the mounting seat 4, so that the mounting seat 4 is flipped to the first position using the lifting device. Furthermore, the step S2 may also include: after the mounting seat 4 reaches the first position, the first limiting shaft 442 is passed between the first limiting member 441 and the fixing plate 443 on the second support seat 2 to fix the mounting seat 4 on the second support seat 2.

[0071] S3, such as Fig.12 As shown, the small diameter end 62 of the tower 6 is fixed on the third support seat 3, and the large diameter end 61 of the tower 6 is fixed on the mounting seat 4, so that the tower 6 is in a horizontal state. Further, the fixing of the large diameter end 61 of the tower 6 on the mounting seat 4 in step S3 may include: placing the outer peripheral surface of the large diameter end 61 of the tower 6 on the support base 454 and the rotating member 452, so that the outer peripheral surface of the large diameter end 61 of the tower 6 abuts against the support base 454, the gasket 70 on the support base 454, and the arc surface on the rotating member 452 respectively. The second stopper 461 is vertically moved relative to the main body 40 until the abutting portion 4610 just abuts against the inner peripheral surface of the large diameter end 61 of the tower 6, the first through hole on the stopper 4611 is aligned with the nearest second through hole on the positioning plate 4620, and the second stopper shaft 4621 is penetrated through the first through hole and the second through hole, so that the second stopper 461 can be fixed at a preset position. Thus, the large diameter end 61 of the tower 6 is fixed on the mounting seat 4. The small diameter end 62 of the tower 6 contacts the arc plate 33 and the gasket 70 on the arc plate 33. Thus, the tower 6 is supported at two points via the third support seat 3 and the mounting seat 4. In addition, the tower 6 and the mounting seat 4 are fixed as a whole.

[0072] Furthermore, step S3 may also include: after the large diameter end 61 of the tower 6 is fixed on the mounting seat 4, the first limiting shaft 442 passed through the first limiting member 441 and the fixing plate 443 on the second support seat 2 is taken out to release the displacement constraint between the mounting seat 4 and the second support seat 2, so that the mounting seat 4 can subsequently rotate relative to the second support seat 2 with the second rotating shaft 432 as the center.

[0073] S4, such as Fig.13As shown, the small diameter end 62 of the tower 6 is lifted by the lifting equipment, and the small diameter end 62 of the tower 6 is separated from the third support seat 3. The tower 6 flips counterclockwise, driving the mounting seat 4 to flip to the initial position, so that the tower 6 is in an inclined state. That is, the central axis of the tower 6 forms an acute angle (approximately 82°) with the ground 71. The driving force for the mounting seat 4 to flip from the first position to the initial position mainly comes from the dead weight of the tower 6. That is, the driving force for the tower 6 to flip from the horizontal state to the inclined state mainly comes from its own weight and the lifting equipment. Specifically, during the process of the mounting seat 4 flipping from the first position to the initial position, the second rotating shaft 432 continues to roll in the second groove 20.

[0074] S5, such as Fig.14 As shown, the winch 5 actively retracts the sling, and the mounting seat 4 continues to flip to the second position, so that the tower 6 is in an upright state. That is, the driving force for the mounting seat 4 to flip from the initial position to the second position mainly comes from the winch 5. That is, the driving force for the tower 6 to flip from the inclined state to the upright state mainly comes from the winch 5. Specifically, during the process of the mounting seat 4 flipping from the initial position to the second position, the first rotating shaft 431 continues to roll in the first groove 10, and the second rotating shaft 432 rolls upward along the guide groove 21, so that the first end 41 of the mounting seat 4 can be tilted upward, that is, the mounting seat 4 continues to rotate counterclockwise at a certain angle until the mounting seat 4 flips from the inclined state to the horizontal state, and the tower 6 flips from the inclined state to the upright state.

[0075] After step S5, the second limit shaft 4621 passing through the first through hole and the second through hole is pulled out, so that the constraint between the tower 6 and the mounting seat 4 can be released, and the tower 6 and the mounting seat 4 can be restored to a separable state. Then, the tower 6 can be lifted off the mounting seat 4 by using a lifting device. Fig.13 As shown, since the mounting base 4 and the first support base 1 together form a lever structure (in the initial position, the first support base 1 abuts against the mounting base 4 at a position of about two-thirds of its length, and the second support base 2 abuts against the end of the first end 41 of the mounting base 4), when the tower 6 is separated from the mounting base 4 (see Fig.14 And after the tower 6 is hidden), the mounting base 4 tends to rotate clockwise around the first rotating shaft 431. At this time, the sling from the winch 5 connected to the first lifting ear 403 provides tension, so that the mounting base 4 rotates slowly and smoothly around the first rotating shaft 431 to the initial position, and the second rotating shaft 432 falls back into the second groove 20 on the second supporting base 2, and the mounting base 4 is naturally reset.

[0076] In summary, in the tower turning method of the present invention, the driving force for the first half of the turning of the tower 6 mainly comes from its own weight and the lifting equipment, and the driving force for the second half of the turning of the tower 6 mainly comes from the winch 5. In the process of turning the tower 6 from the horizontal state to the vertical state, only one lifting device and one winch 5 are needed to complete it. The structure is simple and the turning process is smooth and accurate (gradually transitioning from the first position, the initial position, and the second position). The tower 6 will not shake, and the safety is good. In addition, through the pulling force provided by the winch 5, after the tower 6 is lifted off the mounting seat 4, the mounting seat 4 can be smoothly and automatically reset to the initial position.

[0077] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the scope covered by the claims of the present invention.
