[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, terms such as "installed", "connected", "connected", "fixed", and "set" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, and they can be internal connections between two elements or interactions 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 intervening elements. The terms "first", "second", and "third" are only used to facilitate the description of 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", and "third" 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 To clearly illustrate the structure of the tower-turnover assist device, the physical structure of tower 6 is hidden, and its outline is outlined with dotted lines. When the tower-turnover assist device is in operation, the first support base 1, second support base 2, and third support base 3 are spaced apart from each other, with the second support base 2 located between the first support base 1 and the third support base 3. The first support base 1, second support base 2, and third support base 3 are arranged in a straight line, that is, they extend along the same straight line.

[0045] The third support base 3 is used to support the small-diameter end 62 of the tower 6. The mounting base 4 is used to secure the large-diameter end 61 of the tower 6. Specifically, the diameter of the tower 6 typically gradually changes along its length, so the tower 6 has a large-diameter end 61 and a small-diameter end 62. 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 position, its large-diameter end 61 can be secured by the mounting base 4, while its small-diameter end 62 can be supported and secured by the third support base 3. The third support base 3 and the mounting base 4 provide two-point support for the horizontal tower 6.

[0046] Mounting base 4 is capable of flipping between a first position and a second position. The flipping of tower 6 is primarily driven by the flipping of mounting base 4. Mounting base 4 includes a first end 41 and a second end 42 that are opposite to each other. The direction in which mounting base 4 extends from first end 41 to second end 42 is defined as the longitudinal direction of 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 position, that is, the longitudinal direction of the mounting base 4 is relatively perpendicular to the ground 71. Correspondingly, the tower 6 is in a horizontal position (horizontally positioned), that is, the longitudinal direction of the tower 6 is relatively parallel to the ground 71.

[0048] like Figure 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, while the portion near the second end 42 of the mounting base 4 is supported on the first support base 1. The mounting base 4 is horizontally positioned, with its length parallel to the ground 71. Accordingly, the tower 6 is in an upright position (horizontally positioned), meaning that its length is perpendicular to the ground 71. At this point, the tower 6 has completed its inversion.

[0049] The hoist 5 is arranged on the first support 1 and is connected to the mounting base 4 via a sling. Specifically, the sling can be a wire rope or a chain. Figure 13 As shown, between the first position and the second position, the mounting base 4 will also pass through the initial position. In the initial position, the mounting base 4 itself is balanced and maintained in an inclined state. The mounting base 4 can first flip from the initial position to the first position, connect to 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 base 4 to flip from the initial position to the second position. Specifically, the mounting base 4 first relies on the deadweight pressure of the tower 6 to reach the initial position; then, the mounting base 4 relies on the driving force of the retracted sling of the winch 5 to slowly and steadily reach the second position from the initial position. Thus, the winch 5 is connected to the mounting base 4 through the sling, providing a part of the driving force and stabilizing force for the flipping of the mounting base 4, so that the flipping process of the mounting base 4 is smooth, so that the mounting base 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 base 1, the second support base 2, the third support base 3, the mounting base 4 and the hoist 5, the tower 6 can be safely and smoothly flipped to an upright state. The first support base 1, the second support base 2 and the third support base 3 can be transported to the site independently, and then placed on the ground 71 at intervals. Furthermore, the first support base 1, the second support base 2, the third support base 3, the mounting base 4 and the hoist 5 are independent objects. For example, the mounting base 4 and the second support base 2 can be detachably connected; the hoist 5 can be detachably arranged on the first support base 1. Thus, the first support base 1, the second support base 2, the third support base 3, the mounting base 4 and the hoist 5 can be transported to the site independently for installation, which further facilitates transportation and installation.

[0051] In summary, the tower flip auxiliary device of the present invention enables the tower 6 to flip safely and smoothly to an upright state through the mutual cooperation and coordinated work of the first support base 1, the second support base 2, the third support base 3, the mounting base 4 and the winch 5. In addition, since the first support base 1, the second support base 2 and the third support base 3 are arranged at intervals from each other when the tower flip auxiliary device is in the working state, the tower flip auxiliary device of the present invention adopts a modular design. The first support base 1, the second support base 2 and the third support base 3 can be transported to the site independently and then placed on the ground 71 at intervals from each other. It has a simple structure, a small footprint and is easy to transport. The winch 5 is connected to the mounting base 4 through a sling, providing a part of the driving force for the flipping of the mounting base 4, so that the flipping process of the mounting base 4 is smooth, so that the mounting base 4 drives the tower 6 thereon to flip smoothly and accurately to the second position, and no shaking of the tower 6 occurs.

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

[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 provided 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 base 1, and the second rotating shaft 432 is adapted to the second support base 2. During 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 base 2 to obtain a stable supporting force, and the second rotating shaft 432 rotates relative to the second support base 2, thereby driving the main body 40 to rotate, and then driving the tower 6 to flip. Similarly, during 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 base 1 to obtain a stable supporting force, and the first rotating shaft 431 rotates relative to the first support base 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 There are two first rotating shafts 431 and two second rotating shafts 432. In the first position, the two first rotating shafts 431 are respectively located on the upper sides of the two longitudinal beams 401 (near the second end 42 of the mounting base 4), and the two second rotating shafts 432 are respectively located on the lower sides of the two longitudinal beams 401 (corresponding to the first end 41 of the mounting base 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 base 4 further includes a first limiting member 441 and a first limiting shaft 442, and the first limiting member 441 is disposed on the longitudinal beam 401 of the main body 40. In the first position, the first limiting shaft 442 is inserted between the first limiting member 441 and the second support base 2 to fix the mounting base 4 on the second support base 2. Specifically, a fixing plate 443 is provided on the second support base 2 for inserting the first limiting shaft 442. The first limiting shaft 442 is inserted between the first limiting member 441 and the fixing plate 443 on the second support base 2 to fix the mounting base 4 on the second support base 2. Thus, the mounting base 4 is detachably connected to the second support base 2 via the first limiting member 441 and the first limiting shaft 442. When the first limiting shaft 442 is inserted between the first limiting member 441 and the second support base 2, the relative displacement between the mounting base 4 and the second support base 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 has at least one curved surface adapted to the outer circumference of the large-diameter end 61 of the tower 6. The tower support assembly contacts the outer circumference of the large-diameter end 61 of the tower 6 via the curved surface, 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, disposed on the longitudinal beam 401 of the main body 40. The rotating member 452 is disposed above the fixed member 451. It should be noted that the "above" mentioned here refers to the rotating member 452 being disposed above the fixed member 451 when the tower flip assist device is in operation (i.e., when placed on the ground 71 and assembled). The third rotating shaft 453 passes through the rotating member 452, providing a rotational support point for the rotating member 452. The side of the rotating member 452 facing away from the fixed member 451 is provided with a curved surface that mates with the outer circumference of the large diameter end 61 of the tower 6, and the outer circumference of the large diameter end 61 of the tower 6 can contact this curved surface. The side of the rotating member 452 facing the fixed member 451 is provided with a flat surface. The side of the fixed member 451 facing the rotating member 452 is provided with a first inclined surface 4511 and a second inclined surface 4512.

[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 sake of ease 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 outline in FIG, in the third position, a portion of the plane is aligned 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 naturally maintains the third position. Figure 5 As shown in the dotted outline, after the tower 6 contacts the arc surface on the rotating member 452, the rotating member 452 rotates due to the gravity squeeze of the large diameter end 61 of the tower 6, and tends to rotate toward the side of the central axis of the tower 6. Until the rotating member 452 rotates to the fourth position, a part of the plane is in contact with the second inclined surface 4512, and a gap is formed between the other part of the plane and 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, this 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 provided 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 FIG. Figure 4 (center right). 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 a curved surface that matches the outer circumference of the tower 6. As a result, the outer circumference of the tower 6 can contact the curved surface on the rotating member 452 and the curved surface on the support base 454, respectively, to obtain stable and reliable support. Furthermore, a number of gaskets 70 can be provided on the support base 454. The gaskets 70 can be made of nylon. The gaskets 70 contact the outer circumference of the tower 6, which can increase the friction between the support base 454 and the tower 6, providing 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 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 the 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 limiting member 461 includes an abutting portion 4610 and a limiting portion 4611 that are connected as one body. The abutting portion 4610 is generally L-shaped, and its end away from the limiting portion 4611 can abut against the inner circumference of the tower 6. The limiting portion 4611 is provided with a first through-hole. The third limiting member 462 includes a positioning plate 4620 and a second limiting shaft 4621. The positioning plate 4620 is disposed on the main body 40 and is provided with a plurality of second through-holes arranged vertically at intervals. The limiting portion 4611 can be moved vertically up and down so that 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 limiting portion 4611 is aligned with the nearest second through-hole, and the second limiting shaft 4621 is passed through the first through-hole and the second through-hole, thereby fixing the second limiting member 461 in 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 they can fix the second limiting member 461 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 base 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 via a sling, and the second lifting lug 404 is used to connect to a lifting device (not shown). Specifically, the first lifting lug 403 is provided on a side of the main body 40 close to the first support base 1, and the second lifting lug 404 is provided on a side of the main body 40 close to the third support base 3. The first lifting lug 403 and the second lifting lug 404 can be provided on the crossbeam 402 of the main body 40.

[0063] like Figure 7As shown, in some embodiments, the first support base 1 is provided with a first groove 10 and a backing plate 11. The first rotating shaft 431 of the mounting base 4 is adapted to fit within the first groove 10. In the second position, the first rotating shaft 431 is supported within the first groove 10, and the main body 40 is in contact with the backing plate 11. Furthermore, during the process of the mounting base 4 flipping from the initial position to the second position, the first rotating shaft 431 can continue to roll within the first groove 10, thereby achieving the flipping action of the mounting base 4. The number of first grooves 10 matches the number of 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 reassembled separately. In this way, the floor space can be further reduced and transportation can be facilitated. Further, as Figure 7 In the embodiment shown, 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 base 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 engaged with the guide groove 21. When the mounting base 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 base 4. Figure 13 and Figure 14 As shown, between the initial position and the second position, the mounting base 4 performs a lever motion with the first rotating shaft 431 as a fulcrum, 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 base 4. Therefore, the guide groove 21 plays a role in constraining and guiding the first end 41 of the mounting base 4 in the process of flipping the mounting base 4 from the initial position to the second position, and plays an important role in the smooth flipping of the mounting base 4 in the later stage. 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 base 2 includes a second base 22 and two second support beams 23, which are spaced apart. 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 provided on the second base 22. In other words, the second support base 2 utilizes a modular design, allowing the second base 22 and the two second support beams 23 to be transported and reassembled separately. This further reduces the footprint and facilitates transportation.

[0067] like Figure 9 As shown, in some embodiments, the third support base 3 includes a plurality of spaced-apart vertical plates 31, a bottom plate 32, and a curved plate 33. Each vertical plate 31 is connected between the bottom plate 32 and the curved plate 33. The curved plate 33 is adapted to and in contact with the outer circumference 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. Furthermore, a plurality of gaskets 70 may be provided on the curved plate 33. The gaskets 70 may be made of nylon. The gaskets 70 are in contact with the outer circumference of the tower 6 to increase the friction between the curved plate 33 and the tower 6, thereby providing more stable support for the tower 6.

[0068] Accordingly, the present invention also provides a tower turning method, which can be implemented by using the tower turning auxiliary device of any of the above embodiments. Figures 10 to 14 In some embodiments, the tower flipping 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. Figure 10 As shown, the mounting base 4 is set in an initial position. In this initial position, the mounting base 4 is supported on both the second support base 2 and the first support base 1, and the mounting base 4 is tilted relative to the ground 71. In other words, an acute angle (approximately 8°) is formed between the length direction of the mounting base 4 and the ground 71. With the first rotating shaft 431 as the fulcrum, the mounting base 4 and the first support base 1 together form a lever structure. At the same time, the winch 5 is set on the first support base 1 and is connected to the first lifting lug 403 on the mounting base 4 via a sling.

[0070] S2, such as Figure 11As shown, the mounting base 4 is flipped to the first position so that the mounting base 4 is relatively perpendicular to the ground 71. That is, the length direction of the mounting base 4 is perpendicular to the ground 71. During the flipping process of the mounting base 4, the lifting rope of the winch 5 is rolled and extended. Specifically, the hook of the lifting device is connected to the second lifting lug 404 on the mounting base 4, so that the mounting base 4 is flipped to the first position using the lifting device. Furthermore, step S2 can also include: after the mounting base 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 base 2 to fix the mounting base 4 on the second support base 2.

[0071] S3, such as Figure 12 As shown, the small diameter end 62 of the tower 6 is fixed to the third support base 3, and the large diameter end 61 of the tower 6 is fixed to the mounting base 4, so that the tower 6 is in a horizontal position. Furthermore, the fixing of the large diameter end 61 of the tower 6 to the mounting base 4 in step S3 may include: placing the outer circumference of the large diameter end 61 of the tower 6 on the support base 454 and the rotating member 452, so that the outer circumference 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 of the rotating member 452, respectively. The second limiting member 461 is vertically moved relative to the main body 40 until the abutting portion 4610 just abuts against the inner circumference of the large diameter end 61 of the tower 6, the first through hole of the limiting portion 4611 is aligned with the nearest second through hole of the positioning plate 4620, and the second limiting shaft 4621 is inserted through the first through hole and the second through hole, thereby fixing the second limiting member 461 in the preset position. Thus, the large-diameter end 61 of the tower 6 is fixed to the mounting base 4. The small-diameter end 62 of the tower 6 contacts the curved plate 33 and the gasket 70 on the curved plate 33. Thus, the tower 6 is supported at two points via the third support base 3 and the mounting base 4. Furthermore, the tower 6 and the mounting base 4 are fixed as a single unit.

[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 removed 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 Figure 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 base 3. The tower 6 flips counterclockwise, driving the mounting base 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 base 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 base 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 Figure 14 As shown, the winch 5 actively retracts the sling, further flipping the mounting base 4 to the second position, so that the tower 6 is in an upright state. That is, the driving force for flipping the mounting base 4 from the initial position to the second position mainly comes from the winch 5. That is, the driving force for flipping the tower 6 from the inclined state to the upright state mainly comes from the winch 5. Specifically, during the process of flipping the mounting base 4 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 base 4 can tilt upward, that is, the mounting base 4 continues to rotate counterclockwise by a certain angle until the mounting base 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 limiting shaft 4621 passing through the first through hole and the second through hole is pulled out to release the constraint between the tower 6 and the mounting base 4, so that the tower 6 and the mounting base 4 are restored to a separable state. Then, the tower 6 can be lifted off the mounting base 4 using a lifting device. Figure 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 position of about two-thirds of the length of the mounting base 4, and the second support base 2 abuts against the end of the first end 41 of the mounting base 4), after the tower 6 is separated from the mounting base 4 (see Figure 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 support base 2, and the mounting base 4 is naturally reset.

[0076] In summary, in the tower flipping method of the present invention, the driving force for the first half of the flipping of the tower 6 mainly comes from its own weight and the lifting equipment, and the driving force for the second half of the flipping of the tower 6 mainly comes from the hoist 5. The process of flipping the tower 6 from the horizontal state to the upright state only requires one lifting device and one hoist 5. The structure is simple, and the flipping process is smooth and precise (gradually transitioning from the first position, the initial position, and the second position). There is no shaking of the tower 6, and the safety is relatively good. In addition, due to the pulling force provided by the hoist 5, after the tower 6 is lifted off the mounting base 4, the mounting base 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 methods 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, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
