DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 2As shown, the electric power maintenance lifting platform for wind turbine towers provided in the embodiment of the present application includes a main frame 100, an electric crawler chassis 400, a semicircular collar 500, a fixed storage plate 800, and a movable storage plate 900. The main frame 100 is the main structure of the electric power maintenance platform, and the fixed storage plate 800 is installed on the main frame 100 via a lifting mechanism. The lifting mechanism is composed of pulleys 200 and ropes and other accessories, with a portion of the pulleys 200 located at the top of the main frame 100. Driven by the lifting mechanism, the fixed storage plate 800 moves up and down along the main frame 100.

[0027] A fixed extension rod 300 is fixed to the bottom end of the front side of the main frame 100, which is close to the wind turbine tower. The fixed extension rod 300 is perpendicular to the front side of the main frame 100. The upper surface of the fixed extension rod 300 is provided with multiple positioning holes 310 along the thickness direction. These positioning holes 310 are evenly spaced along the length of the fixed extension rod 300. In addition, the bottom end of the main frame 100 is also equipped with an electric crawler chassis 400, which serves the dual purpose of supporting the main frame 100 and driving its movement.

[0028] In this embodiment, a semicircular collar 500 is provided on the outer surface of the fixed extension rod 300 of the main frame 100. Specifically, an extension portion 510 is provided at each end of the semicircular collar 500. The ends of the extension portions 510 have openings 520, and the extension portions 510 are hollow in structure. The semicircular collar 500 is sleeved on the outer surface of the fixed extension rod 300 of the main frame 100 through the extension portions 510. The top surface of the extension portion 510 is provided with a positioning hole 310 of the same diameter as the fixed extension rod 300. In addition, a locking rod 600 is inserted into the positioning hole 310, which can be used to fix the semicircular collar 500 and the fixed extension rod 300 together.

[0029] The bottom end of the semicircular collar 500 is further connected to the main frame 100 via a first spring 700. Preferably, a connecting plate 530 is provided on the bottom surface of the semicircular collar 500. The connecting plate 530 is perpendicular to the bottom surface of the semicircular collar 500, and the first spring 700 is provided between the connecting plate 530 and the main frame 100. This enables the semicircular collar 500 to have an automatic telescopic function, thereby facilitating the movement of the semicircular collar 500 on the fixed extension rod 300.

[0030] Continue as Figure 1 and Figure 2 As shown, the movable storage plate 900 is sleeved outside the fixed storage plate 800, and the movable storage plate 900 and the fixed storage plate 800 are connected via a second spring 920. Preferably, spring support plates 910 are provided on the sides of the fixed storage plate 800 and the movable storage plate 900, and both ends of the second spring 920 are sleeved on the spring support plates 910.

[0031] In the electric maintenance lifting platform for wind turbine towers provided in an embodiment of the present application, a semicircular collar 500 is placed on the outside of the wind turbine tower, and the extension portion 510 opening 520 of the wind turbine tower is aligned with and inserted into the fixed extension rod 300 of the main frame 100. Subsequently, the positions of the semicircular collar 500 and the fixed extension rod 300 are adjusted according to the actual outer diameter of the wind turbine tower, and the semicircular collar 500 and the fixed extension rod 300 are fixed together by the locking rod 600. Since the movable storage plate 900 and the fixed storage plate 800 are connected by the second spring 920, the movable storage plate 900 can be extended and retracted relative to the fixed storage plate 800 to adjust the storage area of ​​the movable storage plate 900. The above structural design allows staff to adjust the position of the movable storage plate 900 according to the actual damage to the wind turbine tower, and then carry a certain amount of repair materials and maintenance tools to ensure the progress of maintenance.

[0032] In some embodiments, the first spring 700 is located below the fixed extension rod 300, and the outer diameter of the first spring 700 is smaller than the overall width of the fixed extension rod 300. This allows the fixed extension rod 300 to shield the first spring 700, thereby preventing rain from corroding the first spring 700 and shortening its lifespan.

[0033] In some embodiments, a ladder 110 is provided beside the main frame 100, the height of which matches that of the main frame 100. Preferably, a transfer platform 810 is provided beside the fixed storage plate 800, located between the fixed storage plate 800 and the ladder 110. The ladder 110 facilitates timely replenishment of missing repair materials during maintenance, thereby ensuring the smooth progress of maintenance and repair operations.
