Description

Technical Field

[0001] This utility model belongs to the field of wind turbine tower maintenance technology, specifically relating to a wind turbine tower maintenance device. Background Technology

[0002] A wind turbine tower is the support structure for wind power generation. It plays a supporting role in wind turbine generator sets and also absorbs vibrations from the generator set.

[0003] To facilitate maintenance, wind turbine towers are typically equipped with internal ladders. These ladders allow maintenance personnel to inspect different heights of the tower. However, when climbing, maintenance personnel must wear safety protective gear and attach themselves to the ladder using ropes and locks. After reaching a certain height, they must release the locks and reattach themselves to the crossbeam above the ladder. This process is cumbersome, inefficient, and leaves maintenance personnel unprotected, posing a risk of falling during the lock-changing process. Utility Model Content

[0004] The purpose of this utility model is to provide a wind turbine tower maintenance device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower maintenance device, comprising: a ladder body with longitudinal bars and transverse bars, wherein the longitudinal bars are provided with a locking assembly connected to a protective rope, the locking assembly comprising a first C-shaped bracket and a second C-shaped bracket symmetrically distributed, a fixing member for fixing is provided between the first C-shaped bracket and the second C-shaped bracket, a notch for the transverse bar to pass through is formed between the ends of the first C-shaped bracket and the second C-shaped bracket away from the fixing member, and an installation area for wrapping the longitudinal bars is formed between the first C-shaped bracket and the second C-shaped bracket.

[0006] Preferably, one end of the first C-shaped card holder or the second card holder extends horizontally downward with an installation part. An L-shaped pry bar is rotatably provided on the outer side of the installation part. An arc-shaped anti-wear seat that fits against the longitudinal rod is provided on the outer side of the short side of the L-shaped pry bar. A threading hole for connecting the protective rope is provided at the end of the long side of the L-shaped pry bar away from the arc-shaped anti-wear seat. When falling, the arc-shaped anti-wear seat is abutted against the longitudinal rod by lever principle.

[0007] Preferably, the mounting part is provided with a pivot through which the L-shaped pry bar passes, and the L-shaped pry bar is flipped and mounted on the pivot.

[0008] Preferably, the inner wall of the arc-shaped anti-wear seat is provided with a recessed hole extending into the L-shaped pry bar, and the recessed hole is provided with a countersunk bolt connecting the arc-shaped anti-wear seat and the L-shaped pry bar.

[0009] Preferably, the fixing component includes an integrally formed rotating part and a screw. A mounting ring is welded to the outside of the first C-shaped card holder. One end of the second C-shaped card holder extends into the mounting ring. A mounting seat is provided on the outside of the mounting ring. The end of the mounting seat is provided with a rotating groove to accommodate the rotation of the rotating part. One end of the screw is rotatably mounted on the inner wall of the first C-shaped card holder. A threaded hole through which the second C-shaped card holder is threaded onto the screw is provided.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figure 1-2 As shown, the present invention provides a wind turbine tower maintenance device, including a ladder body 1 with longitudinal and transverse bars. The longitudinal bars are provided with a locking assembly connected to a protective rope. The locking assembly includes a first C-shaped bracket 7 and a second C-shaped bracket 10 symmetrically distributed. A fixing member is provided between the first C-shaped bracket 7 and the second C-shaped bracket 10 for fixing. A notch for the transverse bar to pass through is formed between the ends of the first C-shaped bracket 7 and the second C-shaped bracket 10 away from the fixing member. An installation area for wrapping the longitudinal bar is formed between the first C-shaped bracket 7 and the second C-shaped bracket 10.

[0023] As described above, using the ladder body 1 and locking assembly provided by this utility model, the first C-shaped bracket 7 and the second C-shaped bracket 10 are assembled onto the longitudinal bar on the ladder body 1 by means of a fastener. After maintenance personnel climb the ladder body 1, the first C-shaped bracket 7 and the second C-shaped bracket 10 are allowed to rise directly on the longitudinal bar. During the rising process, the notch prevents the crossbar from interfering with the rise.

[0024] In this utility model, combined with Figure 1-2 and Figure 5 As shown, in this embodiment, one end of the first C-type card holder 7 or the second C-type card holder 10 extends horizontally downward with an installation part 5. An L-shaped pry bar 3 is rotatably provided on the outside of the installation part 5. An arc-shaped anti-wear seat 2 that fits against the longitudinal rod is provided on the outside of the short side of the L-shaped pry bar 3. A threading hole for connecting the protective rope is provided at the end of the long side of the L-shaped pry bar 3 that is away from the arc-shaped anti-wear seat 2. When falling, the arc-shaped anti-wear seat 2 is subjected to force and abuts against the longitudinal rod through the lever principle.

[0025] Combination Figure 1-3 As shown, the mounting part 5 is provided with a pivot 4 through which the L-shaped pry bar 3 passes, and the L-shaped pry bar 3 is flipped and mounted on the pivot 4.

[0026] As described above, when using the mounting part 5, L-shaped pry bar 3, and arc-shaped anti-wear seat 2 provided by this utility model, and when the first C-shaped bracket 7 and the second C-shaped bracket 10 are installed on the longitudinal rod, the end of the L-shaped pry bar 3 away from the arc-shaped anti-wear seat 2 tilts upward, while the end of the arc-shaped anti-wear seat 2 abuts against the longitudinal rod. When maintenance personnel fall, the protective rope drives the L-shaped pry bar 3 to press downward through the pivot 4, thereby driving the arc-shaped anti-wear seat 2 to press against the longitudinal rod through the lever principle. In turn, the arc-shaped anti-wear seat 2 prevents the locking mechanism from sliding down the longitudinal rod, thus preventing maintenance personnel from falling to the ground.

[0027] Furthermore, to facilitate the replacement of the arc-shaped anti-wear seat 2, refer to... Figure 6 As shown, the inner wall of the arc-shaped anti-wear seat 2 has a recessed hole 16 extending into the L-shaped pry bar 3. A countersunk bolt 15 connecting the arc-shaped anti-wear seat 2 and the L-shaped pry bar 3 is located in the recessed hole 16. After unscrewing the countersunk bolt 15, the arc-shaped anti-wear seat 2 can be disengaged from the L-shaped pry bar 3, facilitating the replacement of the arc-shaped anti-wear seat 2. Two countersunk bolts 15 are provided, allowing for precise positioning of the arc-shaped anti-wear seat 2 during installation.

[0028] In this utility model, combined with Figure 2-4 As shown, the fastener of this embodiment includes an integrally formed rotating part 6 and a screw 13. A mounting ring 11 is welded to the outside of the first C-shaped bracket 7. One end of the second C-shaped bracket 10 extends into the mounting ring 11. A mounting seat 8 is provided on the outside of the mounting ring 11. The end of the mounting seat 8 is provided with a rotating groove 12 to accommodate the rotation of the rotating part 6. One end of the screw 13 is rotatably mounted on the inner wall of the first C-shaped bracket 7. A threaded hole 14 is threaded through the second C-shaped bracket 10 and threaded onto the screw 13. The screw 13 rotates to move the second C-shaped bracket 10 closer to or away from one side of the first C-shaped bracket 7.

[0029] As described above, using the fastener provided by this utility model, the screw 13 is installed on the first C-shaped bracket 7 and the second C-shaped bracket 10 by the mounting ring 11. The mounting base 8 provides a rotation mounting position for the rotating part 6 on the mounting ring 11. When the first C-shaped bracket 7 and the second C-shaped bracket 10 are distributed on both sides of the longitudinal rod, rotating the rotating part 6 will drive the screw 13 to rotate, thereby driving the first C-shaped bracket 7 to move to one side of the second C-shaped bracket 10, so that the first C-shaped bracket 7 and the second C-shaped bracket 10 fit against the longitudinal rod. At this time, the rotation of the rotating part 6 is stopped. At this time, the first C-shaped bracket 7 and the second C-shaped bracket 10 will not detach from the longitudinal rod. At the same time, the first C-shaped bracket 7 and the second C-shaped bracket 10 can be raised and lowered on the longitudinal rod.

[0030] Furthermore, to prevent the rotating part 6 from rotating on its own, refer to Figure 4As shown, a locking bolt 9 extending into the rotating groove 12 is threaded through the exterior of the mounting base 8, and one end of the locking bolt 9 abuts against the outer wall of the rotating part 6. After the first C-type bracket 7 and the second C-type bracket 10 are installed on the longitudinal rod, the locking bolt 9 is rotated to lock the rotating part 6 in the mounting base 8, thereby preventing maintenance personnel from accidentally touching the rotating part 6 and causing the first C-type bracket 7 and the second C-type bracket 10 to separate, thus improving the stability of the installation of the first C-type bracket 7 and the second C-type bracket.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
