In the climbing frame for wind turbine maintenance provided in the embodiment of the present application, the first ladder frame and the second ladder frame can be used side by side during normal use. When the length of the climbing frame needs to be extended to meet actual use, the second ladder frame can be pulled out to the outside of the U-shaped frame until the second ladder frame is pulled to the expected length. Subsequently, the first ends of the first locking hook and the second locking hook are respectively contacted with the rollers, and then the locking holes of the second ends of the first locking hook and the second locking hook are aligned, and the fasteners are inserted into the locking holes to lock the rollers through the first locking hook and the second locking hook. In other words, the locked rollers can fix the second ladder frame at a preset height of the U-shaped frame. With the above-mentioned structural design, the position of the second ladder frame relative to the first ladder frame can be adjusted according to actual conditions, thereby realizing the function of extending the length of the climbing frame. Moreover, with this structural design, there is no need to splice the climbing frame, thereby greatly avoiding the cumbersome splicing process.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 4As shown, the wind turbine maintenance climbing frame provided by the embodiment of the present application includes a first ladder frame 100, a U-shaped frame 200, a plurality of rollers 300, a first locking hook 400 and a second locking hook 500, a second ladder frame 700 and a fastener 800, wherein the first ladder frame 100 can be regarded as a separate climbing frame, and a plurality of first ladder beams 110 are arranged on the first ladder frame 100. A U-shaped frame 200 is connected to the side of the first ladder frame 100, and the U-shaped frame 200 and the first ladder frame 100 are designed to be of equal length. The U-shaped frame 200 is a frame structure with a cavity inside, and the U-shaped frame 200 includes a first side wall 220 of a vertical section and a second side wall 230 of a horizontal section, and the first side wall 220 and the second side wall 230 are perpendicular to each other, and the first side wall 220 and the second side wall 230 are both provided with vertically extending strip holes 210.

[0030] like Figure 3 As shown, a plurality of rollers 300 are rotatably disposed on the inner wall surfaces of the two first side walls 220 of the U-shaped frame 200 , and the plurality of rollers 300 are evenly distributed beside the inner wall surfaces of the first side walls 220 , and the plurality of rollers 300 are located inside the U-shaped frame 200 .

[0031] The second ladder frame 700 is a climbing frame structure similar to the first ladder frame 100, and a plurality of second ladder beams 710 are arranged on the second ladder frame 700. The second ladder frame 700 is arranged in the U-shaped frame 200 by rolling through a plurality of rollers 300, so that the second ladder frame 700 can move up and down relative to the first ladder frame 100 and the U-shaped frame 200 by the rolling action of the rollers 300. Figure 2 As shown, when the second ladder frame 700 extends out of the U-shaped frame 200, the second ladder frame 700 and the first ladder frame 100 can be spliced ​​and used, thereby extending the overall length of the climbing frame.

[0032] In this embodiment, the first locking hook 400 and the second locking hook 500 are both disposed in the vertically extending strip hole 210. Figure 4 As shown, the first end of the first locking hook 400 contacts the roller 300, and the second end of the first locking hook 400 extends to the side of the second wall of the U-shaped frame 200. In contrast, the first end of the second locking hook 500 contacts the roller 300 on the opposite side, and the second end of the second locking hook 500 extends to the side of the second wall of the U-shaped frame 200 and is located above the second end of the first locking hook 400.

[0033] Specifically, the second end of the first locking hook 400 overlaps with the second end of the second locking hook 500, and the overlapping portion of the two is further provided with a locking hole 600. When the locking holes 600 of the first locking hook 400 and the second locking hook 500 overlap, the first ends of the first locking hook 400 and the second locking hook 500 are both in contact with the roller 300, and the roller 300 is in a stationary state. The fastener 800 is fixed in the locking holes 600 of the first locking hook 400 and the second locking hook 500 by threaded connection. Preferably, a star-shaped handle 900 for easy use can be provided at the end of the fastener 800. In addition, the fastener 800 can also pass through the locking hole 600 and contact the second side wall 230 of the U-shaped frame 200, which can further improve the stability of the connection.

[0034] In the climbing frame for wind turbine maintenance provided in the embodiment of the present application, the first ladder frame 100 and the second ladder frame 700 can be used side by side during normal use. When the length of the climbing frame needs to be extended to meet actual use, the second ladder frame 700 can be pulled out to the outside of the U-shaped frame until the second ladder frame 700 is pulled to the expected length. Subsequently, the first ends of the first locking hook 400 and the second locking hook 500 are respectively contacted with the roller 300, and then the locking holes 600 of the second ends of the first locking hook 400 and the second locking hook 500 are aligned, and the fastener 800 is inserted into the locking hole 600 to lock the roller 300 through the first locking hook 400 and the second locking hook 500. That is, the locked roller 300 can fix the second ladder frame 700 at a preset height of the U-shaped frame 200. With the above structural design, the position of the second ladder frame 700 relative to the first ladder frame 100 can be adjusted according to actual conditions, thereby realizing the function of extending the length of the climbing frame. Moreover, this structural design does not require splicing of the climbing frame, thereby greatly avoiding the cumbersome splicing process.

[0035] In some embodiments, the width of the strip hole 210 provided on the second side wall 230 is greater than the thickness of the second locking hook 500, so that the second locking hook 500 can slide in the strip hole 210. When the second locking hook 500 moves in the strip hole 210 in a direction away from the roller 300, the roller 300 can roll normally without being abutted. On the contrary, if the second locking hook 500 moves in the strip hole 210 in a direction close to the roller 300, the roller 300 will abut against the second locking hook 500 and remain stationary. The above structural design can realize the locking or unlocking function through the second locking hook 500.

[0036] In some embodiments, when the first ladder beam 110 overlaps with the second ladder beam 710, the cross-sectional shape formed by the first ladder beam 110 and the second ladder beam 710 is V-shaped, which can provide a certain depression for workers to step on, thereby improving safety during high-altitude operations.
