[0025] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0026] Embodiments of this application provide a construction platform 10 for a wind turbine tower, such as... Figure 1 and Figure 2 As shown, the construction platform 10 of the wind turbine tower includes: a support platform 100, a working platform 200, and a traveling assembly 300. The support platform 100 is provided with an annular slide rail 110, which is used to surround the outer periphery of the wind turbine tower. The working platform 200 is located on the support platform 100 and is used to rotate around the tower. The traveling assembly 300 is located at the bottom of the working platform 200 and includes traveling wheels 310, which are tactilely connected to the annular slide rail 110.

[0027] In this embodiment, at least part of the support platform 100 is located below the working platform 200. The support platform 100 is a hollow ring platform and provides structural support for the working platform 200. The working platform 200 provides a working space for workers, enabling them to stand on the working platform 200 and carry out construction on the wind turbine tower.

[0028] The working platform 200 has a traveling component 300 on its bottom surface. The working platform 200 can be a fan-shaped platform, and the traveling component 300 is located at the outer arc end of the fan-shaped platform. The working platform 200 is movably connected to the support platform 100 through the traveling component 300. The wind turbine tower includes a tower section. The support platform 100 is provided with an annular slide rail 110 that can surround the outer circumference of the tower section. The annular slide rail 110 is located on the outer edge of the support platform 100. The traveling wheels 310 of the traveling component 300 are rotatably connected to the annular slide rail 110. The traveling wheels 310 can roll along the annular slide rail 110, allowing the working platform 200 to rotate around the outer circumference of the tower section on the support platform 100 for construction operations in different positions.

[0029] For example, the annular slide rail 110 can be composed of multiple sub-slide rails spliced ​​together, and the number of work platforms 200 can be multiple. Each work platform 200 has multiple traveling components 300 at its bottom. Specifically, the annular slide rail 110 includes two sub-slide rails, the number of work platforms 200 is two, and the number of traveling components 300 is four. Each sub-slide rail is provided with two traveling components 300 and one work platform 200.

[0030] By setting a walking component 300 below the work platform 200, the work platform 200 can be rolled to the support platform 100 through the walking wheels 310 of the walking component 300. Compared with the traditional sliding connection method, this reduces the friction generated by the work platform 200 during movement, improves the convenience and flexibility of the work platform 200 movement, and reduces the driving energy consumption of the work platform 200.

[0031] For example, the bottom surface of the work platform 200 may also be provided with a support member. The support member is located at the inner arc end of the fan-shaped platform. The support member is rolled or slidably connected to the support platform 100, so that the work platform 200 is supported more evenly, thereby making the movement of the work platform 200 more stable.

[0032] In some embodiments provided in this application, such as Figure 2As shown in the figure, the annular slide rail 110 includes: a top plate 111, an intermediate plate 112, and a bottom plate 113. The intermediate plate 112 is connected to the bottom of the working platform 200. The top plate 111 and the bottom plate 113 are respectively connected to the intermediate plate 112. The top plate 111 and the bottom plate 113 are arranged opposite to each other. At least part of the traveling wheels 310 are located between the top plate 111 and the bottom plate 113 and are in rolling connection with the bottom plate 113.

[0033] In this embodiment, the end portions of the top plate 111 and the bottom plate 113 are respectively connected to the intermediate plate 112, a spacing is formed between the top plate 111 and the bottom plate 113, and the top plate 111, the bottom plate 113, and the intermediate plate 112 are connected in sequence to form an opening, so that the cross-section of at least part of the annular slide rail 110 is in a 'C'-shaped structure. Specifically, the annular slide rail 110 can adopt an integrally formed structure. The opening of the annular slide rail 110 faces the traveling wheels 310 of the traveling assembly 300. The traveling wheels 310 press on the bottom plate 113, and the direction of the center of gravity of the traveling wheels 310 is the same as the direction of abutting against the bottom plate 113, so that the pressure of the working platform 200 borne by the traveling wheels 310 can be fully applied to the bottom plate 113 through rolling, enabling the traveling assembly 300 to drive the working platform 200 to move more smoothly.

[0034] Exemplarily, the traveling wheels 310 are in rolling connection with the top plate 111, so that both the upper and lower ends of the traveling wheels 310 abut against the inner side of the annular slide rail 110, and both ends of the traveling wheels 310 are limited, further improving the smoothness of the movement of the traveling assembly 300 and preventing the working platform 200 from tilting.

[0035] In some embodiments provided by the present application, as Figure 2 shown, an installation groove is provided on the traveling wheels​​​​​In some embodiments provided in this application, such as Figure 1 and Figure 3 As shown, the support platform 100 is provided with a gear ring 120, which is used to surround the outer periphery of the tower. The working platform 200 includes a fence 210. The construction platform 10 also includes a drive assembly 400 and a control device 500. The drive assembly 400 is located on the working platform 200 and is connected to the gear ring 120 to drive the working platform 200 to rotate around the gear ring 120. The control device 500 is located on the fence 210 and is used to control the movement of the drive assembly 400.

[0038] In this embodiment, the gear ring 120 is an external gear ring, located inside the annular slide rail 110, and coaxially arranged with the annular slide rail 110. The drive assembly 400 below the work platform 200 is connected to the gear ring 120, and the drive assembly 400 can drive the work platform 200 to rotate along the gear ring 120. A fence 210 is provided on the work platform 200 to enclose the work area. A control device 500 is provided on the fence 210, which can be a PLC (Programmable Logic Controller). The control device 500 is communicatively connected to the drive assembly 400, enabling the control device 500 to control the operation of the drive assembly 400, improving the convenience of operation for the operator. When the operator needs to change the work position, they can control the drive assembly 400 by manipulating the control device 500 on the fence 210, thereby driving the work platform 200 to rotate around the tower and adjust the work position.

[0039] In some embodiments provided in this application, such as Figure 3 As shown, the drive assembly 400 includes: a drive member 410, a worm 420, a worm wheel 430, and a gear 440. The drive member 410 is disposed on the working platform 200 and is used to drive the worm 420 to rotate. The worm wheel 430 is connected to the worm 420. The gear 440 is coaxially connected to the worm wheel 430 and meshes with the gear ring 120.

[0040] In this embodiment, the drive unit 410 can be a servo motor or a stepper motor. The drive unit 410 is located on the bottom surface of the work platform 200 and is communicatively connected to the control device 500. The control device 500 is used to control the operation of the drive unit 410. The output shaft of the drive unit 410 is coaxially connected to the worm gear 420. The worm gear 420 and the worm wheel 430, and the gear 440 and the gear ring 120 respectively cooperate with each other.

[0041] When the drive assembly 400 is running, the drive component 410 drives the worm wheel 430 to rotate via the worm 420, which in turn drives the coaxial gear 440 to rotate. This causes the gear 440 to rotate around the gear ring 120, thereby driving the work platform 200 to move and change its position relative to the support platform 100. Because the worm wheel 430 and worm 420 have self-locking properties, the drive assembly 400 achieves a reverse self-locking function; that is, only the worm wheel 430 can drive the worm wheel 430 to rotate, and vice versa. When the drive assembly 400 is not in a driven state, the gear 440 is locked, preventing it from rotating and avoiding the work platform 200 from rotating on its own due to external wind forces. This reduces safety hazards associated with working at heights and improves the safety of construction operations.

[0042] For example, the drive assembly 400 also includes a rotating shaft 450, with a worm gear 430 and a gear 440 respectively splined onto the rotating shaft 450. A mounting bracket 230 is provided on the bottom wall of the work platform 200, and the worm gear 420 and the rotating shaft 450 are rotatably connected to the mounting bracket 230, making the movement of the drive assembly 400 smoother. The construction platform 10 also includes a power supply 900, which is located on the bottom surface of the support platform 100 and provides power to the drive component 410 and the control device 500. The power supply 900 can be a battery.

[0043] In some embodiments provided in this application, such as Figure 4 As shown, the support platform 100 is provided with a central hole 130 for surrounding the tower. The construction platform 10 also includes a plurality of telescopic rods 600, which are spaced apart circumferentially along the central hole 130. Any telescopic rod 600 is used for radial extension and retraction along the central hole 130. The fixed end of the telescopic rod 600 is connected to the support platform 100, and the telescopic end of the telescopic rod 600 is used to abut against the tower.

[0044] In this embodiment, the support platform 100 is fitted onto the outer periphery of the wind turbine tower through a central hole 130. The bottom surface of the support platform 100 is provided with multiple power telescopic rods 600 extending radially along the central hole 130, spaced circumferentially around the central hole 130. Each telescopic rod 600 can be an electric actuator and is electrically connected to a control device 500. The fixed end of each telescopic rod 600 is connected to the support platform 100. When the telescopic rod 600 extends towards the center of the central hole 130, its telescopic end abuts against the tower, securing the support platform 100 to the tower and improving the stability and ease of installation during construction. When the telescopic rod 600 retracts away from the center of the central hole 130, a gap is created between its telescopic end and the tower, releasing the connection between the support platform 100 and the tower for subsequent construction operations.

[0045] For example, the telescopic end of the telescopic rod 600 is provided with a push head 610. The telescopic rod 600 abuts against the tower through the push head 610. The abutting surface of the push head 610 is an arc-shaped surface. The arc-shaped surface protrudes in a direction away from the center of the central hole 130. The bending dimension of the arc-shaped surface is adapted to the outer diameter of the tower.

[0046] In some embodiments provided in this application, such as Figure 4 As shown, the construction platform 10 also includes a support ring frame 700, which is located on the bottom surface of the support platform 100 and surrounds the outer periphery of the central hole 130. The fixed end of the telescopic rod 600 is connected to the support ring frame 700.

[0047] In this embodiment, a support ring frame 700 is provided below the support platform 100, surrounding the central hole 130, which improves the structural strength and support strength of the support platform 100. The fixed end of the telescopic rod 600 is located on the support ring frame 700, which provides installation space and structural support for the telescopic rod 600.

[0048] In some embodiments provided in this application, such as Figure 4 and Figure 5 As shown, the support ring frame 700 includes: an inner ring plate 710, an outer ring plate 720, and a connecting plate 730. The inner ring plate 710 surrounds the outer periphery of the central hole 130. The telescopic end of the telescopic rod 600 is slidably connected to the inner ring plate 710. The outer ring plate 720 surrounds the outer periphery of the inner ring plate 710. The fixed end of the telescopic rod 600 is connected to the outer ring plate 720. The two ends of the connecting plate 730 are respectively connected to the outer ring plate 720 and the inner ring plate 710.

[0049] In this embodiment, the inner ring plate 710 and the outer ring plate 720 are connected to the bottom surface of the support platform 100. The outer ring plate 720 and the inner ring plate 710 can be circular or polygonal in shape, and are fitted and surround the outer periphery of the central hole 130. The fixed end of the telescopic rod 600 is located on the outer ring plate 720, and the telescopic end of the telescopic rod 600 is movably connected to the inner ring plate 710 and extends into the inner side of the inner ring plate 710. The support ring frame 700 provides support and limit for both ends of the telescopic rod 600, making the telescopic rod 600 more stable during telescopic movement.

[0050] For example, the telescopic end of the telescopic rod 600 is provided with a guide rod 620, which is connected to the push head 610 and slidably connected to the inner ring plate 710.

[0051] In some embodiments provided in this application, such as Figure 1 and Figure 3 As shown, the work platform 200 also includes a fixing ring 220, which is located on the fence 210 of the work platform 200 and is used to connect a safety rope.

[0052] In this embodiment, the fence 210 is provided with a fixing ring 220. When workers are working, they connect the safety rope to the fixing ring 220 to prevent workers from falling, reduce safety hazards, and especially improve the safety of high-altitude construction operations.

[0053] In some embodiments provided in this application, such as Figure 1 As shown, the construction platform 10 also includes a lifting lug 800, which is located on the support platform 100.

[0054] In this embodiment, lifting lugs 800 are provided on the wall of the central hole 130. There are multiple lifting lugs 800. When installing the construction platform 10, the entire construction platform 10 is lifted by connecting the lifting lugs 800 with steel wire ropes and then fitted onto the outside of the wind turbine tower. This improves the convenience of installation and movement of the construction platform 10.
