[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] like Figures 1 to 5 As shown, a maintenance platform for wind turbine blades includes a platform body 1, with extension mechanisms on both sides of the platform body 1. Each extension mechanism includes an extension frame 2, a dual-axis motor 3, and adjusting blocks 4. Mounting grooves 11 are provided on both sides of the platform body 1, and the extension frame 2 is slidably disposed within the mounting grooves 11. Adjusting grooves 12 are provided on the side walls of the mounting grooves 11, and adjusting blocks 4 are provided on both sides of the outer side wall of the extension frame 2. The adjusting blocks 4 penetrate and slidably are disposed within the adjusting grooves 12; the dimensions of the adjusting blocks 4 are adapted to the adjusting grooves 12.
[0023] The dual-axis motor 3 is fixedly installed in the middle of the outer wall of the extension frame 2. The output ends of the dual-axis motor 3 are connected to lead screws 31. A support plate 13 is provided on the outer wall of the extension frame 2. The lead screw 31 is rotatably mounted on the support plate 13. The adjusting block 4 is installed on the lead screw 31.
[0024] When maintenance of wind turbine blades is required, the lifting device, such as a lifting platform, is activated to move the platform body 1 to a suitable height. Before lifting, the operator can start the dual-axis motor 3, which drives the lead screw 31 to rotate and the adjusting block 4 to slide, so that the extension frame 2 extends from both sides of the platform body 1 until it reaches the required maintenance position. The operator can then perform maintenance work such as cleaning, inspection, and repair of the wind turbine blades on the platform.
[0025] By setting up the extension mechanism, the overall working space of the platform body 1 can be expanded, making it easier for staff to maintain the wind turbine blades. At the same time, it can be customized and adjusted according to different maintenance needs when maintaining wind turbine blades of different sizes and shapes, thereby improving the overall applicability of the platform body 1.
[0026] The platform body 1 has a slot 16 inside. The extension frame 2 has a telescopic plate 21 on one side facing the middle of the platform body 1. One end of the telescopic plate 21 is connected to the inside of the extension frame 2 by a spring 22, and the other end extends into the slot 16. The size of the telescopic plate 21 is adapted to the slot 16.
[0027] By setting the telescopic plate 21 in cooperation with the spring 22, when the extension frame 2 extends to both sides of the platform body 1, the telescopic plate 21 can always be inserted into the slot 16 under the action of the spring 22, maintaining the stability of the bottom plane between the platform body 1 and the extension frame 2, and improving the safety of the staff during maintenance.
[0028] The bottom of the mounting groove 11 is provided with a sliding groove 14, and a connecting rod 15 is provided in the sliding groove 14. The bottom of the extension frame 2 is provided with a slider 23, and the slider 23 slides in cooperation with the connecting rod 15.
[0029] By setting the sliding groove 14 and the connecting rod 15 to slide with the slider 23, the stability of the extension frame 2 is enhanced, making the extension frame 2 less prone to shaking or tilting during sliding, improving the overall stability of the device, ensuring the safety of operators on the platform, and improving the efficiency of maintenance work.
[0030] The inner sidewall of the mounting groove 11 is provided with a guide hole 17, and the two sidewalls of the extension frame 2 are provided with guide rods 24, which slide in conjunction with the guide hole 17.
[0031] The coordinated design of guide hole 17 and guide rod 24 improves the sliding accuracy of extension frame 2, enabling extension frame 2 to accurately reach the required maintenance position, which helps to improve the efficiency and accuracy of maintenance work, enhances the stability of extension frame 2, and makes extension frame 2 less prone to shaking or tilting during sliding.
[0032] The working principle of this utility model is as follows: First, by starting the lifting device, such as the lifting platform, the platform body 1 is moved to a suitable height so that the staff can easily access the wind turbine blades. Before the lifting operation, the dual-axis motor 3 can be started to drive the lead screw 31 to rotate and drive the adjusting block 4 to slide, so that the extension frame 2 extends from both sides of the platform body 1 until it reaches the required maintenance position. The operator can then perform maintenance work such as cleaning, inspection, and repair of the wind turbine blades on the platform.
[0033] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
