Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0044] The following combination Figures 1-21 The utility model describes a wind turbine tower lifting system.

[0045] The present invention provides a wind turbine tower lifting system. Figure 1 and Figure 4 As shown, it includes a tower 10, an anti-sway bracket 20, an anti-sway rod 30 and an elevator 40. The anti-sway bracket 20 is fixed to the inner wall of the tower 10 to form an escape passage for the elevator 40 to pass through. When the elevator 40 is located below the anti-sway bracket 20, the anti-sway rod 30 is set on the anti-sway bracket 20 and horizontally arranged at the top of the escape passage. Figure 2 and Figure 3 As shown, the anti-sway rod 30 is provided with an anti-sway through hole 31 for the safety wire rope 110 and the traction wire rope 120 to pass through. When the elevator 40 passes through the avoidance channel and moves from the bottom of the anti-sway bracket 20 to the top of the anti-sway bracket 20, as shown in FIG. Figure 6 As shown, the anti-sway bar 30 is mounted on the top of the elevator 40 and runs together with the elevator 40.

[0046] In one embodiment, the anti-sway bracket 20 is U-shaped and includes three frames. The ends of two opposing frames are fixed to the inner wall of the tower 10, and a gap is formed between the other frame and the inner wall of the tower 10. Thus, the anti-sway bracket 20 and the inner wall of the tower 10 cooperate to form an escape passage. In another embodiment, the anti-sway bracket 20 is square-shaped, with one side fixed to the inner wall of the tower 10. The hollow area of ​​the anti-sway bracket 20 serves as an escape passage for the elevator 40 to pass through. In yet another embodiment, the anti-sway bracket 20 includes two relatively independent frames, each of which has one end fixed to the inner wall of the tower 10 and the other end suspended. The area between the two frames forms the escape passage. In this embodiment, one end of the anti-sway bar 30 is attached to one frame, and the other end is attached to the other frame. It is understood that the anti-sway bracket 20 can be configured in different shapes as needed, as long as it can support the anti-sway bar 30 and does not interfere with the upward and downward movement of the elevator 40.

[0047] Optionally, the anti-sway bar 30 can be a straight bar or a bent bar. Figure 3As shown, the anti-sway bar 30 includes a rod body 32 and an anti-sway plate 33. The anti-sway plate 33 is fixed to the rod body 32. Both ends of the rod body 32 are respectively mounted on the anti-sway bracket 20. The anti-sway through hole 31 is provided on the anti-sway plate 33. In another specific embodiment, the anti-sway bar 30 is a bare rod, which only includes the rod body 32. The anti-sway through hole 31 is provided on the rod body 32. The embodiment of the present utility model does not specifically limit the setting position of the anti-sway through hole 31. Usually, the safety wire rope 110 and the traction wire rope 120 are installed in parallel in the middle of the elevator 40. The anti-sway bar 30 is provided with two anti-sway through holes 31. The two anti-sway through holes 31 are spaced apart, such as Figure 1 、 Figure 4 and Figure 6 As shown, one of the anti-sway holes 31 is for the safety wire rope 110 to pass through, and the other anti-sway hole 31 is for the traction wire rope 120 to pass through. It can be understood that the apertures of the two anti-sway holes 31 are slightly larger than the thickness of the safety wire rope 110 and the traction wire rope 120, so that the safety wire rope 110 and the traction wire rope 120 can swing slightly within the anti-sway holes 31. As long as the two anti-sway holes 31 are used to keep the safety wire rope 110 and the traction wire rope 120 at a certain distance from each other, they will not be entangled.

[0048] like Figure 1 and Figure 4 As shown, when the lift 40 is located below the anti-sway bracket 20, the anti-sway rod 30 is placed on the anti-sway bracket 20. As the lift 40 moves upward, the lift 40 lifts up the anti-sway rod 30, separating the anti-sway rod 30 from the anti-sway bracket 20, and then moves upward synchronously with the lift 40. Figure 6 As shown, when the elevator 40 is located above the anti-sway bracket 20, the anti-sway bar 30 is mounted on top of the elevator 40 and moves upward with the elevator 40. As the elevator 40 descends, the anti-sway bar 30 moves downward under the force of gravity along the safety wire rope 110 and the traction wire rope 120. When the elevator 40 passes through the avoidance passage and moves below the anti-sway bracket 20, the anti-sway bar 30 is blocked by the anti-sway bracket 20 and remains mounted on the anti-sway bracket 20, no longer moving downward. When the elevator 40 is operating below the anti-sway bracket 20, the two spaced anti-sway through holes 31 ensure that the safety wire rope 110 and the traction wire rope 120 maintain a certain distance, preventing them from becoming entangled due to the movement of the elevator 40 and the shaking of the tower 10. When the elevator 40 runs above the anti-sway bracket 20, the anti-sway bar 30 opens a path in front at the top of the elevator 40 as the elevator 40 runs, preventing the safety wire rope 110 and the traction wire rope 120 from swinging and getting entangled significantly, and preventing the safety wire rope 110 and the traction wire rope 120 from getting entangled with other accessories in the tower 10.

[0049] The wind turbine tower lifting system provided by the embodiment of the present invention has an anti-sway bracket 20 fixedly installed in the tower 10, and an anti-sway rod 30 is set up and placed on the anti-sway bracket 20. When the elevator 40 passes over the anti-sway bracket 20 from bottom to top, the anti-sway rod 30 is transferred from the anti-sway bracket 20 to the top of the elevator 40; when the elevator 40 passes over the anti-sway bracket 20 from top to bottom, the anti-sway rod 30 is transferred from the top of the elevator 40 to the anti-sway bracket 20. During the entire movement process, the anti-sway through hole 31 provided on the anti-sway rod 30 allows the safety wire rope 110 and the traction wire rope 120 to maintain a certain distance to avoid entanglement during shaking.

[0050] In a specific embodiment, if Figure 6 As shown, to prevent the anti-sway bar 30 from shaking when it moves with the elevator 40 at the top of the elevator 40, a mounting slot 42 is provided at the top of the elevator 40. When the anti-sway bar 30 is mounted at the top of the elevator 40, the anti-sway bar 30 is received in the mounting slot 42, which constrains the anti-sway bar 30's radial freedom of movement. It will be appreciated that the mounting slot 42 extends in the same direction as the axial direction of the anti-sway bar 30.

[0051] The mounting slots 42 can be formed directly into the top plate of the elevator 40 or indirectly provided on the top of the elevator 40. For example, the top of the elevator 40 is secured to a retaining member 41 by bolts, and the mounting slots 42 are provided on the retaining member 41. Optionally, the mounting slots 42 are provided in pairs, with the opposing ends of the anti-sway bar 30 respectively received within the mounting slots 42 on the corresponding side. Of course, only one mounting slot 42 can be provided, as long as it can constrain the radial movement of the anti-sway bar 30 to a certain extent.

[0052] Preferably, the opposite side walls of the installation slot 42 are arranged at an acute angle, which can provide guidance for the anti-sway bar 30 to enter the installation slot 42 and constrain the freedom of movement of the anti-sway bar 30. For example, the installation slot 42 is a V-shaped slot.

[0053] Therefore, by setting a mounting groove 42 at the top of the elevator 40, the radial movement freedom of the anti-sway bar 30 is constrained, thereby improving its stability when it moves with the elevator 40 at the top of the elevator 40, and more effectively preventing the safety wire rope 110 and the traction wire rope 120 from being entangled.

[0054] In one embodiment, one of the elevator 40 and the anti-sway bar 30 is provided with a limiting groove, and the other is provided with a limiting portion. When the anti-sway bar 30 is mounted on top of the elevator 40, the limiting portion is received in the limiting groove to constrain the anti-sway bar 30's axial freedom of movement.

[0055] Specifically, the direction in which the limiting groove extends is perpendicular to the direction in which the mounting through-slot 42 extends. For example, a limiting groove may be provided on the top of the elevator 40, and a limiting portion configured to cooperate with the limiting groove may be constructed on the anti-sway bar 30. In another example, a limiting groove may be provided on the anti-sway bar 30, and a limiting portion may be provided protruding from the top of the elevator 40. The limiting portion may be inserted into the limiting groove to constrain the axial freedom of movement of the anti-sway bar 30. Of course, both the limiting groove and the limiting portion may also be provided on the elevator 40, with the anti-sway bar 30 having a matching limiting portion corresponding to the limiting groove on the elevator 40, and a matching limiting groove corresponding to the limiting portion on the elevator 40.

[0056] Therefore, by providing the installation through slot 42 and the limiting slot, the anti-sway bar 30 cannot rotate in the horizontal plane, thereby preventing the anti-sway bar 30 from shaking significantly due to the movement of the elevator 40.

[0057] Optional, such as Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, two limiting guide plates 50 are fixedly mounted on the anti-sway bar 30, and the two limiting guide plates 50 cooperate to form a limiting portion. The top of the elevator 40 has two guide surfaces 43, and the two guide surfaces 43 are arranged oppositely to form a limiting groove. Figure 6 As shown, when the anti-sway bar 30 is set on the top of the elevator 40, the two limiting guide plates 50 are arranged in a one-to-one correspondence with the two guide surfaces 43, thereby restricting the axial movement freedom of the anti-sway bar 30.

[0058] The guide surfaces 43 can be any plane inclined relative to the horizontal plane. To facilitate the entry of the anti-sway bar 30, both guide surfaces 43 are inclined relative to the horizontal plane, thereby forming a limit groove that is wide at the top and narrow at the bottom. As the elevator 40 moves upward, the two inclined guide surfaces 43 can guide the anti-sway bar 30 to fall into the bottom of the limit groove when the anti-sway bar 30 is misaligned. The two guide surfaces 43 are arranged relative to each other to form a groove body. Because the limit guide plates 50 are fixedly connected to the anti-sway bar 30, the two limit guide plates 50 are arranged in a one-to-one correspondence with the two guide surfaces 43, preventing the anti-sway bar 30 from moving axially, thereby stabilizing the position of the anti-sway bar 30 relative to the top of the elevator 40 and more effectively preventing the safety wire rope 110 and the traction wire rope 120 from becoming entangled.

[0059] The limiting groove can be directly formed on the top of the elevator 40 or by other structural components. For example, two vertical plates can be installed on the top of the elevator 40. These two vertical plates and the top of the elevator 40 together form the limiting groove, and the opposing sides of the two vertical plates serve as the two guide surfaces 43. It should be noted that the number of limiting guide plates 50 can be two, three, or four, as long as the two limiting guide plates 50 can cooperate with the two guide surfaces 43 to constrain the freedom of movement of the anti-sway bar 30.

[0060] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, the limiting guide plate 50 includes a first plate and a second plate. The second plate is arranged at an obtuse angle to the first plate. The second plate is provided with a groove. The anti-sway bar 30 is fixed to the first plate and clamped in the groove. The first plate is fixed to the bottom of the anti-sway bar 30 by screws.

[0061] In a preferred embodiment, if Figure 1 、 Figure 4 and Figure 6 As shown, a limit member 41 is mounted on the top of the elevator 40, with a guide surface 43 located on one sidewall of the limit member 41. A mounting slot 42 is provided on the limit member 41, extending through the guide surface 43. Optionally, to facilitate the entry of the anti-sway bar 30, the sidewall of the guide surface 43 of the limit member 41 can be tilted relative to the horizontal plane. Specifically, the limit member 41 is M-shaped, with a V-shaped mounting slot 42 formed in the middle to constrain the anti-sway bar 30, and inclined guide surfaces 43 provided on the sides. The two sides of the M-shaped limit member 41 are fixedly connected to the top of the elevator 40 by bolts.

[0062] Furthermore, a guide member may be provided at the top of the elevator 40. The guide member includes a through slot extending in the same direction as the elevator 40 is raised and lowered, with the bottom end of the slot blocked by the top wall of the elevator 40. When the elevator 40 ascends, the anti-sway bar 30 enters the slot from the end away from the elevator 40 and descends along the slot until the bottom end of the slot abuts against the top wall of the elevator 40. The slot walls on opposite sides of the slot constrain the anti-sway bar 30's radial freedom of movement, while the two opposing guide members constrain the anti-sway bar 30's axial freedom of movement. Alternatively, a positioning post may be provided on one of the elevator 40 and a positioning hole on the other. The positioning hole and the positioning post cooperate to keep the anti-sway bar 30 relatively fixed as it moves with the elevator 40.

[0063] like Figure 2 As shown, the anti-sway bracket 20 includes a frame 21 and a pin holder 22. Two pin holders 22 are disposed on opposite sides of the frame 21. Each pin holder 22 has a directional slot 221 extending in the same direction as the lift 40. The two ends of the anti-sway bar 30 are received in corresponding directional slots 221.

[0064] For a wire rope guided elevator, the anti-sway bracket 20 can be directly fixed to the inner wall of the tower 10. For example, Figure 2 and Figure 3As shown, the frame 21 includes a transverse support 211 and opposing first and second frames 212 and 213. One end of the first frame 212 is fixedly connected to the inner wall of the tower 10 via bolts, and the other end is also bolted to the transverse support 211. One end of the second frame 213 is fixedly connected to the inner wall of the tower 10 via bolts, and the other end is also bolted to the transverse support 211. One pin holder 22 is bolted to the first frame 212, and the other pin holder 22 is also bolted to the second frame 213. The transverse support 211 is U-shaped, and the first, second, and transverse frames 212, 213, and transverse support 211 form a U-shape when connected. To enhance the installation stability of the anti-sway bracket 20, the frame 211 also includes a reinforcement plate 214. Specifically, the reinforcement plates 214 are provided on the outer sides of the first and second frames 212 and 213, respectively. The free ends of the reinforcement plates 214 are fixedly connected to the inner wall of the tower 10.

[0065] For a ladder-guided elevator, the anti-sway bracket 20 can adopt the frame 21 described above, or other forms of frame 21 to connect with the ladder 140. For example, Figure 5 As shown, the frame 21 includes a transverse support 217, a side support 215, and a transverse frame 216. The two side supports 215 are arranged opposite to each other and connected by the transverse frame 216 to form a U-shaped frame. The two pin seats 22 are fixed to the two side supports 215 by bolts in a one-to-one correspondence. The inner sides of the two side supports 215 are respectively provided with a transverse support 217. The ends of the transverse support 217 are in the shape of a pressure plate so as to be connected to the ladder 140. In order to improve the fixing strength of the frame 21, the frame 21 also includes a diagonal brace 218. The ends of the diagonal brace 218 are fixedly connected to the inner wall of the tower 10 by bolts. The diagonal brace 218 can be arranged above or below the side support 215, or can be arranged above and below the side support 215 at the same time. The diagonal brace 218 is provided as a reinforcement structure to improve the stability of the installation of the anti-sway bracket 20.

[0066] The pin holder 22 is provided with an oriented slot 221. The opposing side walls of the oriented slot 221 constrain the radial freedom of movement of the anti-sway bar 30. The two pin holders 22 cooperate to constrain the axial freedom of movement of the anti-sway bar 30, thereby ensuring that the anti-sway bar 30 remains relatively fixed to the anti-sway bracket 20 when mounted on the anti-sway bracket 20. Optionally, the width of the oriented slot 221 gradually decreases from top to bottom, allowing the larger opening to facilitate entry of the anti-sway bar 30 into the oriented slot 221 and guide the anti-sway bar 30 to gradually fall into the bottom end of the oriented slot 221.

[0067] like Figure 7As shown, two anti-sway bars 30 are mounted on the same anti-sway bracket 20. Preferably, there are multiple anti-sway bars 30, spaced apart along the height of the tower 10. It will be appreciated that the anti-sway through holes 31 on the multiple anti-sway bars 30, for mounting the same steel wire rope, are coaxially arranged to ensure that all anti-sway bars 30 can be mounted on the safety wire rope 110 and the traction wire rope 120. The anti-sway bars 30 and anti-sway bracket 20 can be located at the top and / or middle of the tower 10, depending on the specific environment of the tower 10.

[0068] In order to effectively constrain the relative position of the anti-sway bar 30 and the elevator 40, a limiter 41 is staggered on the top of the elevator 40. For example, there are two anti-sway bars 30, and the two anti-sway bars 30 are spaced apart along the height direction of the tower 10. The two sets of limiters 41 are staggered on the top of the elevator 40. When both anti-sway bars 30 are set on the top of the elevator 40, as shown in FIG. Figure 6 As shown, one of the anti-sway rods 30 is constrained by a set of limiting members 41 , and the other anti-sway rod 30 is constrained by another set of limiting members 41 .

[0069] like Figures 8 to 21 As shown, the wind turbine tower lifting system provided by the embodiment of the present invention further includes a cable sheath 60, which is fixed to the tower 10. Figure 10 、 Figure 12 and Figure 14 As shown, the elevator 40 is provided with a cutter 44. The side cables 150 of the elevator 40 are connected to the cutter 44 and have a gap with the outer wall of the elevator 40. As the elevator 40 ascends, the cutter 44 pushes open the cable sheath 60, allowing the side cables 150 of the elevator 40 to enter the cable sheath 60 and be restrained by the cable sheath 60. As the elevator 40 descends, the cutter 44 opens the cable sheath 60, allowing the side cables 150 of the elevator 40 to move out of the cable sheath 60, thereby releasing the side cables 150 of the elevator 40.

[0070] In addition to the safety wire rope 110 and the traction wire rope 120, Figure 10 、 Figure 12 、 Figure 14 、 Figure 15 As shown, the side of the elevator 40 is also provided with power cables and other side cables 150 such as wire ropes. Figure 11 、 Figure 13 and Figure 16 As shown, the cable sheath 60 is fixed to the anti-sway bracket 20. Alternatively, as shown Figure 14 As shown, the cable sheath 60 is located below the anti-sway bracket 20 and is fixed to the inner wall of the tower 10 through a separate mounting bracket 65. Of course, the cable sheath 60 can also be located above the anti-sway bracket 20.

[0071] The cutter 44 is a plate or a cylinder. Figure 10 、 Figure 12 and Figure 14 As shown, the cutter 44 is in the shape of a vertical plate. As the elevator 40 moves upward, the top end of the cutter 44 contacts the cable sheath 60, opening the cable sheath 60, allowing the side cables 150 installed on the cutter 44 to directly enter the cable sheath 60 and be restrained by the cable sheath 60. As the elevator 40 moves downward, the bottom end of the cutter 44 contacts the cable sheath 60, opening the cable sheath 60, allowing the side cables 150 installed on the cutter 44 to move out of the cable sheath 60 along with the cutter 44. Figure 14 and Figure 17 As shown, the cutter 44 is cylindrical, through which the side cables 150 pass to connect to the electrical components within the elevator 40. Optionally, the cutter 44 gradually converges from the center toward the ends, resulting in a pointed tip at both the top and bottom of the cutter 44. When the cutter 44 contacts the cable sheath 60, the pointed tip of the cutter 44 smoothly cuts through the cable sheath 60.

[0072] Specifically, when the lift 40 moves from below the cable sheath 60 to above it, the cutter 44 pushes open the cable sheath 60, allowing the side cables 150 of the lift 40 to enter the cable sheath 60 and be restrained by the cable sheath 60. When the lift 40 is operating above the cable sheath 60, the side cables 150 are always contained within the cable sheath 60. The cable sheath 60 constrains the movement range of the side cables 150, preventing the side cables 150 from becoming entangled with other structures due to excessive swinging. When the lift 40 moves from above the cable sheath 60 to below it, the cutter 44 opens the cable sheath 60, allowing the side cables 150 of the lift 40 to move out of the cable sheath 60, thereby releasing the side cables 150 of the lift 40. When the lift 40 is operating below the cable sheath 60, the side cables 150 are no longer restrained by the cable sheath 60.

[0073] like Figure 8 and Figure 9 As shown, the cable sheath 60 includes a mounting base 61, a first clamping block 62, and a second clamping block 63. The first clamping block 62, the second clamping block 63, and the mounting base 61 are connected to form a restraining hole 64. The mounting base 61 is fixed to the tower 10. The first end of the first clamping block 62 and the first end of the second clamping block 63 are both fixed to the mounting base 61. The second end of the first clamping block 62 and the second end of the second clamping block 63 are stacked one above the other. As the elevator 40 is raised or lowered, the cutter 44 separates the first clamping block 62 and the second clamping block 63, allowing the side cable 150 to pass into or out of the restraining hole 64.

[0074] Among them, the first clamp block 62 and the second clamp block 63 are U-shaped blocks, and the open ends of the two U-shaped blocks are arranged opposite to each other. One side arm of the U-shaped block is screwed to the mounting seat 61, and the other side wall of the U-shaped block overlaps with the other U-shaped block. In order to facilitate cutting the overlapping part of the first clamp block 62 and the second clamp block 63, the first clamp block 62 and the second clamp block 63 are flexible blocks with a certain hardness. When the cutter 44 acts on the area where the first clamp block 62 and the second clamp block 63 are stacked up and down, the first clamp block 62 and the second clamp block 63 are deformed to form an opening, and the cutter 44 passes through the cable sheath 60 and brings the side cable 150 into the constraint hole 64. At least the stacking area of ​​the first clamp block 62 and the second clamp block 63 is a flexible structure. For example, the first clamp block 62 and the second clamp block 63 are both rubber parts. For another example, only the stacking area of ​​the first clamp block 62 and the second clamp block 63 is a rubber part, which can be deformed under the action of the cutter 44.

[0075] For a plurality of different side cables 150, the cable sheath 60 may be provided only for some of the side cables 150. The elevator 40 has a first side wall, a second side wall, a third side wall and a fourth side wall connected in sequence. The first side wall and the third side wall are arranged opposite to each other and parallel to the anti-sway bar 30. The first side wall is closer to the connection end of the anti-sway bracket 20 and the tower 10 than the third side wall. For a wire rope guided elevator, such as Figure 10 、 Figure 12 、 Figure 14 、 Figure 15 and Figure 17 As shown, the first side wall is installed with two side cables 150, namely the first side cable and the second side cable, and the cable sheath 60 can be set only for one side cable 150. Figure 11 As shown, the anti-sway bracket 20 is fixedly mounted with a connecting rod 219, which is arranged in parallel with the anti-sway rod 30. The connecting rod 219 is fixedly mounted with a cable sheath 60 corresponding to the first side cable. Figure 13 As shown, the connecting rod 219 is fixed with a cable sheath 60 corresponding to the second side cable. Figure 14 As shown, there is only one cable sheath 60 , which is disposed below the anti-sway bracket 20 to constrain the second side cable.

[0076] For the ladder-guided elevator, the first side wall, the second side wall and the fourth side wall are all equipped with side cables 150. Figure 16 As shown, the cable sheath 60 is fixed to the side bracket 215 and is arranged corresponding to the side cable 150 installed on the second side wall or the fourth side wall. Figure 17 As shown, the cable sheath 60 is fixed to the ladder 140 and is arranged corresponding to the side cable 150 installed on the first side wall.

[0077] Multiple cable sheaths 60 are provided for the same side cable 150. For example, two cable sheaths 60 are provided at intervals along the height direction of the tower 10, with one cable sheath 60 fixedly mounted on the anti-sway bracket 20 and the other cable sheath 60 located above or below the anti-sway bracket 20 to improve the restraint on the side cable 150.

[0078] Cable sheaths 60 are provided for different side cables 150, such as Figure 18 and Figure 20 As shown, multiple cable sheaths 60 can be set at the same height of the tower 10; Figure 19 and Figure 21 As shown, multiple cable sheaths 60 can also be set at different heights of the tower 10. It can be understood that since different side cables 150 are located at different positions, the multiple cable sheaths 60 arranged for different side cables 150 are at different positions on the horizontal plane. For example, the multiple cable sheaths 60 used to constrain different side cables 150 are all set on the anti-sway bracket 20 or are all set above or below the anti-sway bracket 20, and the specific setting position corresponds to the position of the side cable 150. Taking the wire rope guided elevator as an example, Figure 18 As shown, two cable sheaths 60 are provided for two different side cables 150. Both cable sheaths 60 are fixed to the anti-sway bracket 20 and are located on the connecting rod 219 of the anti-sway bracket 20. Alternatively, as shown in FIG. Figure 20 As shown, two cable sheaths 60 are provided for two different side cables 150. The two cable sheaths 60 are fixed to the same mounting bracket 65 and fixed to the bottom of the anti-sway bracket 20 by means of the mounting bracket 65. For another example, multiple cable sheaths 60 are provided for different side cables 150. Some cable sheaths 60 are fixed to the anti-sway bracket 20, and the other cable sheaths 60 are fixed to the tower 10 or to the ladder 140 by means of the mounting bracket 65. Figure 19 As shown, two cable sheaths 60 are provided for two different side cables 150, wherein one cable sheath 60 is fixed to the anti-sway bracket 20, and the other cable sheath 60 is fixed below the anti-sway bracket 20 through the mounting bracket 65. Figure 21 As shown, multiple cable sheaths 60 are set for different side cables 150, one of which is fixed to the anti-sway bracket 20, and the other cable sheaths 60 are fixed below the anti-sway bracket 20 through the mounting bracket 65 and are spaced apart along the height direction of the tower 10.

[0079] An embodiment of the present invention further provides a wind turbine, comprising the wind turbine tower lifting system as described above.

[0080] The wind turbine can use a ladder-guided elevator or a wire rope-guided elevator. During the lifting movement of the elevator 40, the anti-sway bar 30 prevents the safety wire rope 110 and the traction wire rope 120 from getting entangled or getting entangled with other accessories in the tower 10, thereby improving the smooth operation of the elevator 40 and reducing the number of maintenance times.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
