[0002] The tower plays a primary supporting role in wind turbines and also absorbs vibrations. Precast concrete wind turbine towers are typically frustoconical structures with a constant taper. The angle between the tower wall and the tower's central axis is approximately 2.5°. The concrete tower is composed of several segments, with an overall height of approximately 160m, and a radial variation of more than 4m between the top and bottom. The currently common construction method for precast concrete wind turbine towers is to set up a construction platform inside the tower for hoisting and installing the segments.

[0036] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present invention and do not limit the present invention.

[0037] The present invention provides a construction platform device for hoisting a wind turbine tower, such as Figure 1-8 As shown, the hoisting construction platform device includes a construction platform 100 and a platform base 200 rotatably connected to the construction platform 100, and the platform base 200 is provided with a first drive motor 201 for driving the construction platform 100 to rotate around the central axis; the construction platform 100 includes a basic frame 101 and a plurality of extension platforms 102 movably connected to the basic frame 101, and the basic frame 101 is provided with a second drive motor 103 for driving the plurality of extension platforms 102 to move radially outward.

[0038] The hoisting construction platform device of the present invention solves the construction problem in the gaps between the extended platforms after the extended platforms are radially extended by arranging the construction platform to be able to rotate around the central axis relative to the platform base. That is, when construction work needs to be carried out in the gaps between the extended platforms, the first drive motor installed in the platform base is started to drive the construction platform to rotate around the central axis by a certain angle, so that the corresponding extended platform is rotated to the area to be constructed, thereby avoiding the occurrence of construction blind spots.

[0039] According to an embodiment of the present invention, Figure 4 and Figure 5As shown, a first transmission shaft 104 extending axially downward into the platform base 200 and a first driven gear 105 fixedly connected coaxially to the first transmission shaft 104 are fixedly mounted at the center of the base frame 101. The output end of the first drive motor 201 is fixedly connected to the driving gear 202, with the first driven gear 105 meshing with the driving gear 202. Preferably, the diameter of the driving gear 202 is smaller than that of the first driven gear 105. This arrangement can reduce the rotational speed of the first transmission shaft 104, improve the rotational torque, and improve the stability of the device.

[0040] According to an embodiment of the present invention, Figure 1-3 As shown, the platform base 200 includes a base 203, an axle seat 204, and a buffer seat 206. The first drive motor 201 is disposed within the base 203; the axle seat 204 is fixedly connected to the base 203 above the base 203 and coaxially therewith. An axial hole 205 is defined at the center of the axle seat 204, extending axially therethrough. The first transmission shaft 104 extends into the base 203 through the axial hole 205; the buffer seat 206 is movably connected to the base 203 coaxially therewith below the base 203, with a buffer spring 207 disposed between the buffer seat 206 and the base 203.

[0041] Specifically, if Figure 3 As shown, the bottom surface of the seat body 203 is fixedly connected to a plurality of buffer columns 214 distributed at equal intervals along the circumferential direction and extending axially downward. The top surface of the buffer seat 206 is fixedly connected to a plurality of rod sleeves 215 corresponding to the plurality of buffer columns 214. The plurality of buffer columns 214 are axially movably sleeved in the plurality of rod sleeves 215. A buffer spring 207 is sleeved on the outer side of each buffer column 214 and rod sleeve 215. Further preferably, as Figure 2 As shown, a buffer air cushion 216 is provided at the bottom of the buffer seat 206. The provision of a buffer spring and a buffer air cushion can improve the buffering performance of the hoisting construction platform device when it lands.

[0042] According to an embodiment of the present invention, Figure 2 、 Figure 3 and Figure 5 As shown, a concave ring 208 is provided on the outer circumference of the shaft seat 204, and a shaft sleeve 106 is provided on the base frame 101 surrounding the first transmission shaft 104. The shaft sleeve 106 is fixedly connected to the lower end surface of the base frame 101 via a plurality of support rods 123 distributed at equal intervals along the circumference, and the shaft sleeve 106 is rotatably embedded in the concave ring 208. This arrangement can achieve mutual support between the construction platform 100 and the platform base 200 in the axial direction, and realize the rotation of the construction platform 100 about the central axis relative to the platform base 200 under the drive action of the first drive motor 201, while limiting the movement of the construction platform 100 relative to the platform base 200 in the axial direction.

[0043] According to an embodiment of the present invention, Figure 1-3As shown, the platform base 200 further includes multiple groups of hydraulic rods 209 and telescopic rods 210 distributed at equal intervals along the circumference. Each hydraulic rod 209 extends radially and is provided with a rotating ball 211 and a suction cup 212 fixedly connected to the rotating ball 211 at one end away from the base 203. One end of the telescopic rod 210 is hinged to the hydraulic rod 209, and the other end is hinged to the buffer seat 206. Preferably, the hydraulic rod 209 is provided with a damping ball seat 213 at the end away from the base 203, and the rotating ball 211 is rotatably disposed in the damping ball seat 213.

[0044] By making the hydraulic rod 209 extend and retract radially so that the suction cup 212 adsorbs the inner wall of the tower, the purpose of positioning the hoisting construction platform device in tower sections of different sizes is achieved, thereby improving the stability of the device; by utilizing the rotation of the rotating ball 211, it is possible to adjust to the inner wall of the tower with different curvatures and tapers to achieve the positioning function; by providing a telescopic rod 210 and making its two ends hinged to the hydraulic rod 209 and the buffer seat 206 respectively, it can extend and retract and provide support as the length of the hydraulic rod 209 changes, thereby improving the load-bearing capacity.

[0045] According to an embodiment of the present invention, Figure 5-8 As shown, the second drive motor 103 is located at the center of the base frame 101 and the output end is fixedly connected to the second transmission shaft 107. The second transmission shaft 107 extends axially downward and is coaxially fixedly connected to the gear disc 108 located in the base frame 101. The base frame 101 is provided with a plurality of expansion slots 109 extending radially. A plurality of expansion platforms 102 are respectively arranged in the plurality of expansion slots 109 in a radially movable manner. Each expansion platform 102 is fixed with a screw sleeve 110 and a lead screw 111 threadedly connected to the screw sleeve 110. A second driven gear 112 is coaxially fixed to one end of each lead screw 111. Each second driven gear 112 is meshed with the gear disc 108. Preferably, as Figure 1 and Figure 4 As shown, a protective shell 122 is provided at the top center of the construction platform 100 , and the second drive motor 103 is located in the protective shell 122 .

[0046] When the hoisting construction platform device needs to be expanded outward or retracted inward according to the inner diameter of the tower to be constructed, the second drive motor 103 is started to rotate the second transmission shaft 107 together with the toothed disc 108, thereby driving each second driven gear 112 to rotate together with the lead screw 111, and then through the threaded connection between the screw sleeve 110 fixedly set on the inner end face of the expansion platform 102 and the lead screw 111, each expansion platform 102 is driven to slide outward or inward synchronously in the radial direction, thereby realizing the outward expansion or inward retraction of the hoisting construction platform device. Preferably, the inner end face of each expansion platform 102 is also provided with two guide sleeves 120 respectively located on both sides of the screw sleeve 110, and accordingly, each expansion slot 109 is fixed with two guide columns 121 extending radially outward from its inner end face, and the guide sleeve 120 is movably sleeved on the guide column 121, thereby preventing the expansion platform from offsetting when moving. Preferably, a limit portion is provided at one end of the guide column 121 away from the center of the construction platform to prevent the expansion platform 102 from moving further outward when the expansion platform 102 is expanded to the maximum limit position.

[0047] According to an embodiment of the present invention, Figure 4 and Figure 5 As shown, a radially extending limiting groove 113 is provided at the bottom of each expansion slot 109, and a limiting slider 114 is provided at the bottom of each expansion platform 102 to match the limiting groove 113. The limiting slider 114 can be slidably embedded in the limiting groove 113. Preferably, each expansion slot 109 is provided with two limiting grooves 113, and each expansion platform 102 is correspondingly provided with two limiting sliders 114 to improve stability.

[0048] According to an embodiment of the present invention, Figure 1 、 2 As shown in Figures 6 and 8, each expansion platform 102 is fixed with symmetrical ring segments 115 and an annular sleeve 116 that can be slidably connected to the ring segments 115 along the circumferential direction on both sides. The two ends of the annular sleeve 116 are respectively placed on the two ring segments 115 between the two adjacent expansion platforms 102, so that all the ring segments 115 and the annular sleeve 116 form a circular ring centered on the central axis of the construction platform. When the expansion platform 102 expands outward, the ring segments 115 and the annular sleeve 116 move radially outward while the two move relative to each other along the circumferential direction, that is, the ring segments 115 gradually move out from the inside of the annular sleeve 116 to form a circular ring with a larger diameter, thereby achieving communication between the expansion platforms 102 after expansion, further improving work efficiency. Preferably, a limit bar is provided at the end of the ring segment 115. When the end of the ring segment 115 moves to the opening position of the annular sleeve 116, the limit bar and the opening of the annular sleeve form a stop to prevent the ring segment 115 from completely separating from the annular sleeve 116. Preferably, the top surfaces of the basic frame 101 , the expansion platform 102 and the annular sleeve 116 are all provided with anti-slip pads.

[0049] According to an embodiment of the present invention, Figure 1 、 2 As shown in Figures 4 and 5, the upper end surface of the base frame 101 is provided with an annular groove 117 and a slip ring 118 rotatably connected to the annular groove 117. The upper end surface of the slip ring 118 is provided with a plurality of hoisting posts 119 distributed at equal intervals along the circumference. When the first drive motor 201 drives the construction platform 100 to rotate, the rotational connection between the slip ring 118 and the base frame 101 ensures that the top hoisting rope will not become tangled.

[0050] The hoisting construction platform device of the present invention can be operated as follows: the concrete tower is hoisted by an external hoisting machine, and the hoisting construction platform is hoisted by connecting the hoisting column 119. After it is lifted to a suitable construction height, it can be adjusted to the concrete tower with different curvatures and tapers by the telescopic effect of the hydraulic rod 209 and the rotation effect of the rotating ball 211, thereby pushing the suction cup 212 to adsorb the inner wall of the concrete tower to achieve the positioning purpose of the hoisting construction platform device and improve stability; when it is necessary to perform a diameter change operation on the construction platform 100, the second drive motor 103 is started to make the second transmission shaft 107 rotate together with the gear plate 108, thereby driving the second driven gear 112 to rotate together with the lead screw 111, and with the help of the sliding action of the limiting slider 114 in the limiting slide groove 113, each expansion platform 102 is driven to slide synchronously outward in the radial direction. The first extension platform 102 is connected to the second extension platform 102 by the first drive motor 201, and the second extension platform 102 is connected to the second extension platform 102 by the first drive motor 201.
