[0035] The fan tower drum system of the present application will be described below with reference to FIGS. 1-11.

[0036] As shown in FIGS. 1-11, the wind turbine tower system comprises a tower, a cable guide frame 20 and a landing platform 30. A guide device 40 is installed in the tower, and an elevator 100 can move up and down along the guide device 40. The cable guide frame 20 is slidably installed on the guide device 40, and the landing platform 30 is fixed in the tower. The cable guide frame 20 is provided with a cable through hole 21 for the cable to pass through. When the elevator 100 moves above the landing platform 30, the cable guide frame 20 can move along the guide device 40 together with the elevator 100; when the elevator 100 moves below the landing platform 30, the cable guide frame 20 is arranged on the landing platform 30.

[0037] As shown in FIGS. 1-8, for the ladder guide elevator, the guide device 40 is a ladder 41. As shown in FIGS. 9-11, for the wire rope guide elevator, the guide device 40 is a guide wire rope 42. The elevator 100 can move up and down along the guide device 40. As shown in FIGS. 3, 8 and 10, the cable guide frame 20 is provided with two cable through holes 21, one of which is used for the traction wire rope 110 to pass through, and the other is used for the safety wire rope 120 to pass through. It can be understood that the two cable through holes 21 are arranged at intervals, and the interval is equivalent to the interval between the traction wire rope 110 and the safety wire rope 120. Optionally, the hole diameter of the cable through hole 21 is larger than the diameter of the cable, and the cable can slightly sway in the cable through hole 21, avoiding that the cable through hole 21 too much restricts the cable.

[0038] For the ladder guide elevator, as shown in FIGS. 1-5, the landing platform 30 can be directly fixed to the ladder 41. Alternatively, the landing platform 30 is fixed to the inner wall of the tower by a support. Alternatively, as shown in FIGS. 6-8, the landing platform 30 is fixed to the working platform 11 in the tower. For the wire rope guide elevator, the landing platform 30 is fixed to the inner wall of the tower by a support; alternatively, as shown in FIGS. 9-11, the landing platform 30 is fixed to the working platform 11 in the tower. As long as the landing platform 30 can support the cable guide frame 20 and limit the movement position of the cable guide frame 20 when the elevator 100 is below the landing platform 30, the landing of the cable guide frame 20 can be realized. It can be understood that the landing platform 30 does not hinder the up and down movement of the elevator 100, but only abuts against the cable guide frame 20 to restrict the downward movement of the cable guide frame 20. The landing platform 30 is fixed by welding or screwing, and the fixing mode of the landing platform 30 is not specifically limited in the embodiment of the present application.

[0039] For the cable guide of the ladder guide, as shown in FIG. 1 to FIG. 8, the cable guide frame 20 is in the shape of a ring square frame or a flat plate, one side frame is in sliding fit with the ladder 41 through the guide wheel 51, and the other side frame is provided with the cable through hole 21 for the safety wire rope 120 and the traction wire rope 110 to pass through. For the wire rope guide, as shown in FIG. 9 to FIG. 11, the cable guide frame 20 is in the shape of a strip plate, both ends of which are in sliding fit with the guide wire rope 42 through the guide wheel 51, and the middle part is provided with the cable through hole 21 for the safety wire rope 120 and the traction wire rope 110 to pass through.

[0040] During the lifting of the elevator 100, the safety wire rope 120 and the traction wire rope 110 can be wound due to large swing amplitude. With the rising of the elevator 100, the cable guide frame 20 moves with the elevator 100 at the top of the elevator 100, and prevents the safety wire rope 120 and the traction wire rope 110 from being wound by means of the cable through hole 21 on the cable guide frame 20, thereby improving the stability of operation. When the elevator 100 is descending, the cable guide frame 20 moves downward along the guide device 40 under the action of gravity. When the elevator 100 runs below the landing platform 30, the cable guide frame 20 is stopped from moving by being placed on the landing platform 30, and stays at the landing platform 30 by being constrained by the landing platform 30. When the elevator 100 rises to above the landing platform 30 again, the cable guide frame 20 moves upward with the elevator 100, thereby preventing the safety wire rope 120 and the traction wire rope 110 from being wound.

[0041] The fan tower system provided by the embodiment of the present application has the landing platform 30 arranged in the tower, the cable guide frame 20 placed on the landing platform 30 and capable of sliding along the guide device 40, the cable guide frame 20 moving synchronously with the elevator 100 and preventing the traction wire rope 110 and the safety wire rope 120 from being wound by means of the cable through hole 21 arranged thereon when the elevator 100 moves upward, thereby ensuring the normal operation of the elevator 100, and the cable guide frame 20 being unable to continue to move when the elevator 100 moves below the landing platform 30, thereby realizing the landing of the cable guide frame 20 and having a simple structure.

[0042] In a specific embodiment, as shown in FIG. 1 to FIG. 8, the guide device 40 is the ladder 41, the cable guide frame 20 is installed on the ladder 41 through the guide wheel 51, and the landing platform 30 is fixed to the ladder 41 or the working platform 11 in the tower.

[0043] As shown in FIG. 1 to FIG. 8, the cable guide frame 20 is in a square shape, which includes a first side frame 201, a second side frame 202, a third side frame 203 and a fourth side frame 204, and the first side frame 201, the second side frame 202, the third side frame 203 and the fourth side frame 204 form a square frame, wherein the second side frame 202 and the fourth side frame 204 are opposite to each other and the same side ends of the second side frame 202 and the fourth side frame 204 are exposed to the third side frame 203, the third side frame 203 is closer to the ladder 41 than the first side frame 201, and the cable through hole 21 is arranged on the first side frame 201. The guide wheels 51 are installed on the parts of the second side frame 202 and the fourth side frame 204 exposed to the third side frame 203 and are located on the opposite sides of the second side frame 202 and the fourth side frame 204, so that when the guide wheels 51 move along the ladder 41, the second side frame 202 and the fourth side frame 204 are located on the outside of the ladder 41 and are not interfered by the ladder 41.

[0044] Specifically, the guide wheels 51 are arranged in pairs, and each pair of guide wheels 51 is rotatably installed on the cable guide frame 20 and clamped on the vertical rods of the ladder 41. As shown in FIG. 1 and FIG. 4, one side of the second side frame 202 facing the fourth side frame 204 and one side of the fourth side frame 204 facing the second side frame 202 are respectively provided with a pair of guide wheels 51, and the two guide wheels 51 on the second side frame 202 are clamped on one side vertical rod of the ladder 41, and the two guide wheels 51 on the fourth side frame 204 are clamped on the other side vertical rod of the ladder 41, so that the cable guide frame 20 can move upwards along the ladder 41. It can be understood that the number of pairs of guide wheels 51 arranged on the second side frame 202 and the fourth side frame 204 can also be two pairs or three pairs, etc., to improve the stability of the movement of the cable guide frame 20.

[0045] In addition, the fan tower system also includes a support arm 52 and a support wheel 53, the support arm 52 is fixed to the cable guide frame 20, and the support wheel 53 is rotatably installed on the support arm 52 and is in sliding fit with the ladder 41.

[0046] As shown in FIG. 4 and FIG. 5, the support arm 52 is installed on the outside of the second side frame 202 and the fourth side frame 204. Optionally, the support arm 52 is a Y-shaped frame or a straight plate, and the connection strength between the cable guide frame 20 and the ladder 41 is improved by additionally arranging the support arm 52. The end of the support arm 52 away from the cable guide frame 20 rotatably installs the support wheel 53. The support wheels 53 are arranged in pairs, and each pair of support wheels 53 is clamped on the vertical rod of the ladder 41, so as to tightly hold the ladder 41 and move up and down along the ladder 41. Thus, the support wheels 53 and the guide wheels 51 are arranged in an up-down interval, which can improve the stability of the sliding of the cable guide frame 20 along the ladder 41.

[0047] In an optional embodiment, as shown in FIG. 4, the docking station 30 includes a vertical plate 31 and a horizontal plate 32, the vertical plate 31 is fixed vertically to the horizontal plate 32, the vertical plate 31 is fixed to the ladder 41, and the horizontal plate 32 is abuttingly arranged with the cable guide frame 20.

[0048] As shown in FIGS. 1-5, the docking platform 30 is an L-shaped plate including a horizontal plate 32 and a vertical plate 31. The vertical plate 31 is fixed to the ladder 41 by a pressing plate 33, and the horizontal plate 32 is located in the gap between the elevator 100 and the ladder 41 and does not interfere with the normal lifting of the elevator 100. Specifically, the cable guide frame 20 further includes a docking plate 205 fixed to the third frame 203, and the docking plate 205 overlaps the horizontal plate 32 of the docking platform 30 to constrain the position of the cable guide frame 20.

[0049] In yet another optional embodiment, the docking platform 30 is fixed to the working platform 11 in the tower tube. The docking platform 30 is provided with positioning columns 34, and the cable guide frame 20 is provided with positioning holes 22. The positioning columns 34 and the positioning holes 22 are correspondingly arranged. When the docking platform 30 and the cable guide frame 20 are abutted, the positioning columns 34 are inserted into the positioning holes 22 to improve the constraint of the docking platform 30 on the cable guide frame 20.

[0050] As shown in FIGS. 6-8, the docking platform 30 is provided with positioning columns 34 on the surface, and the cable guide frame 20 is correspondingly provided with positioning holes 22. When the cable guide frame 20 is overlaid on the docking platform 30, the positioning columns 34 are inserted into the positioning holes 22. Specifically, the positioning columns 34 can be two, three, or more, and the multiple positioning columns 34 are arranged at intervals. Alternatively, the multiple positioning columns 34 are arranged in the same row or staggered in different rows.

[0051] In a specific embodiment, the guide device 40 is a guide steel wire rope 42, and the cable guide frame 20 is in the shape of a strip plate. The two ends of the cable guide frame 20 are respectively connected with the corresponding guide steel wire rope 42 in a sliding manner. The docking platform 30 includes two supporting plates 35, and the two ends of the cable guide frame 20 can be respectively overlapped on the corresponding supporting plates 35.

[0052] As shown in FIGS. 9-11, the cable guide frame 20 is in the shape of a strip plate, and the cable through hole 21 is located in the middle of the cable guide frame 20. The two ends are respectively connected with a guide steel wire rope 42 in a sliding manner. During the lifting of the elevator 100, the cable guide frame 20 is located at the top of the elevator 100 and can move with the elevator 100. The docking platform 30 is fixed to the working platform 11 in the tower tube or fixed to the tower tube by a supporting frame.

[0053] In order to overlay the strip-shaped cable guide frame 20 on the docking platform 30, the docking platform 30 includes two oppositely arranged supporting plates 35, and each supporting plate 35 supports one end of the cable guide frame 20. As shown in FIGS. 9 and 10, the supporting plate 35 is in the shape of L, one of which extends vertically to be fixedly connected with the vertical plate on the working platform 11, and the other of which is horizontally arranged to support the cable guide frame 20.

[0054] The opposite ends of the cable guide frame 20 are respectively provided with a pair of guide wheels 51, and each pair of guide wheels 51 clamps the guide steel wire rope 42 in cooperation.

[0055] The guide wheels 51 are rotatably installed at the ends of the cable guide frame 20. Two guide wheels 51 are arranged at the first end of the cable guide frame 20, and a channel for clamping the guide steel wire rope 42 is formed between the two guide wheels 51. Similarly, two guide wheels 51 are arranged at the second end of the cable guide frame 20, and a channel for clamping another guide steel wire rope 42 is formed between the two guide wheels 51.

[0056] In order to improve the stability of the sliding cooperation between the cable guide frame 20 and the guide steel wire rope 42, a plurality of pairs of guide wheels 51 can be arranged at the ends of the cable guide frame 20. For example, an extension plate is fixedly installed at the end of the cable guide frame 20, and a plurality of pairs of guide wheels 51 are installed on the extension plate, and the extension plate provides sufficient installation space for the plurality of pairs of guide wheels 51. Alternatively, the bottom of the extension plate is flush with the bottom surface of the cable guide frame 20, and the top of the extension plate is higher than the top surface of the cable guide frame 20, so that the extension plate provides sufficient installation space for the guide wheels 51 while ensuring the stability of abutting against the top surface of the docking platform 30. Of course, the bottom of the extension plate can also protrude outwardly from the bottom surface of the cable guide frame 20, and the docking platform 30 is provided with a avoiding hole corresponding to the extension plate.

[0057] As shown in FIGS. 9-11, the supporting plate 35 is provided with an avoiding hole 37 for avoiding the guide wheels 51. When the bottom surface of the cable guide frame 20 is arranged on the surface of the supporting plate 35, part of the guide wheels 51 is accommodated in the avoiding hole 37. By arranging the avoiding hole 37, the size of the guide wheels 51 is not constrained by the thickness of the cable guide frame 20, so that larger guide wheels 51 can be selected, thereby improving the stability of the sliding cooperation with the guide steel wire rope 42.
