[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

The scraping device includes an operating frame 2, a rotating seat 1 and a scraper structure 3. The operating frame 2 includes a first extension arm 21 and a second extension arm 22 arranged at an angle. The rotating seat 1 rotates around the axis of the barrel section to be installed at the top of the barrel section. The rotating seat 1 is located in the angle area between the first extension arm 21 and the second extension arm 22, and is located below the first extension arm 21 and is connected to the first extension arm 21. The operating frame 2 can rotate synchronously with the rotating seat 1. The second extension arm 22 extends downward beyond the lower end of the rotating seat 1, and the rotating seat 1 is an inverted U-shaped structure as a whole to be plugged and matched with the top of the barrel section. The scraper structure 3 is installed at the bottom end of the second extension arm 22, and the scraper 31 of the scraper structure 3 protrudes laterally from the second extension arm 22 toward the side of the rotating seat 1.

[0048] The scraping device provided in this embodiment can install the rotating seat 1 on the top of the cylinder segment. When the rotating seat 1 rotates, the scraper 31 of the scraper structure 3 can be driven by the operating frame 2 to move circumferentially along the outer wall of the cylinder segment, thereby scraping the glue from the area on the outer wall of the cylinder segment that is higher than the ground. In addition, the scraping effect can be made uniform, and it is not easy to bring out the glue at the joint due to excessive local scraping force, which can also save time and effort.

[0049] Furthermore, the length of the second extension arm 22 is adjustable, and the specific adjustment method is a common design and will not be described in detail here.

[0050] Furthermore, the rotating seat 1 includes a top wall 11, and a first side arm 12 and a second side arm 13 respectively connected to both ends of the top wall 11, and a through hole (not shown) is provided on the second side arm 13. The scraping device also includes a clamping structure 15 threadedly connected to the through hole, and the clamping structure 15 cooperates with the first side arm 12 to clamp the outer wall of the cylinder segment, and the second side arm 13 is a side arm on the rotating seat 1 away from the second extension arm 22. When in use, the connection position of the clamping structure 15 and the through hole can be adjusted to adjust the spacing between the first side arm 12 and the clamping structure 15, so as to adapt to cylinder segments of different diameters and wall thicknesses, and the distance between the operating frame 2 and the outer wall of the cylinder segment can be stabilized, thereby stabilizing the scraping force of the scraper structure 3 on the outer wall of the cylinder segment.

[0051] Furthermore, the clamping structure 15 includes a screw 150 threadedly connected to the through hole, an operating portion 152 and a clamping plate 151 fixedly connected to both ends of the screw 150, and the clamping plate 151 is located in the rotating seat 1.

[0052] Furthermore, a ball seat 1510 is installed on the inner side wall of the clamping plate 151, and a ball 17 is rotatably embedded in the ball seat 1510 and protrudes from the ball seat 1510 toward the first side arm 12. The arrangement of the ball 17 facilitates the clamping plate 151 to rotate close to the outer wall of the barrel section, thereby reducing the friction force of the clamping plate 151 on the outer wall of the barrel section.

[0053] Furthermore, a first roller 16 that can roll circumferentially along the outer wall of the cylinder segment is installed on the inner wall of the first side arm 12, and a second roller 18 that can roll along the top wall 11 of the cylinder segment is installed on the top wall 11. In this way, the friction between the rotating seat 1 and the cylinder segment can be reduced, the service life of the scraping device can be extended, and the damage to the cylinder segment can be reduced.

[0054] Furthermore, there is a gap between the top wall 11 and the first extension arm 21, and an ear plate 19 is extended from the top wall 11 toward the first extension arm 21, and the ear plate 19 is rotatably connected to the pivot 211 on the first extension arm 21. An adjustment rod 212 is extended from the first extension arm 21 toward the rotating seat 1, and the adjustment rod 212 deviates from the vertical center line of the top wall 11 and is threadedly connected to the rotating seat 1. In this embodiment, the right end of the top wall 11 is connected to an L-shaped cantilever 14 (such as Figure 2As shown in the figure, the cantilever 14 extends to the right beyond the right end of the top wall 11, and the adjustment rod 212 is threadedly connected to the cantilever 14. In other embodiments, an adjustment rod 212 is provided on the top wall 11 extending toward the first extension arm 21, the adjustment rod 212 deviates from the vertical center line of the top wall 11, and is threadedly connected to the first extension arm 21. Regardless of whether the adjustment rod 212 is provided on the first extension arm 21 or on the top wall 11, the contact force between the scraper 31 on the second extension arm 22 and the cylinder section can be adjusted by adjusting the threaded connection depth of the adjustment rod 212 to adapt to the scraping of the glue on the outer wall of the cylinder section with different diameters, wall thicknesses, and slopes, and the scraping force of the scraper structure 3 on the outer wall of the cylinder section can be adjusted.

[0055] Furthermore, the ear plate 19 is provided with a pivot notch 191 (such as Figure 2 As shown in FIG. 1 , the pivot notch 191 is rotatably matched with the pivot 211 on the first extension arm 21, so that the rotating seat 1 and the operating frame 2 can be easily disassembled to organize and store the scraping device. In this embodiment, there are two ear plates 19, and the two ear plates 19 are arranged to the left away from the vertical center line of the top wall 11, and there are two corresponding pivots 211.

[0056] Furthermore, the scraper 31 is made of polytetrafluoroethylene, which can reduce damage to the cylinder section and reduce adhesion of the glue on the scraper 31, thereby ensuring the scraping effect and reducing the cleaning frequency of the scraper 31.

[0057] Furthermore, the scraper structure 3 includes the aforementioned scraper 31, and also includes a U-shaped plate 32 rotatably mounted on the bottom end of the second extension arm 22, the opening of the U-shaped plate 32 faces the side of the second extension arm 22 facing the rotating seat 1, and there is a gap between the U-shaped plate 32 and the side wall of the second extension arm 22 facing away from the rotating seat 1. The scraper 31 is fixed on the support arm 321 of the U-shaped plate 32. In this way, the scraping force of the scraper 31 on the outer wall of the cylinder section can be fine-tuned to further ensure the uniformity of the scraping effect, and the scraper can also fit the outer wall of the cylinder section to adapt to the outer walls of the cylinder section with different inclinations.

[0058] Furthermore, a camera is provided at the bottom end of the second extension arm 22 so as to observe the scraping effect in real time and adjust the scraping force of the scraper 31 on the cylinder section in real time when necessary.

[0059] Furthermore, a first rope lock 213 is provided at the end of the first extension arm 21, and a second rope lock 221 is also provided at the middle of the second extension arm 22. One end of a recovery rope (not shown) passes through the first rope lock 213 and hangs down to the ground, and the other end passes through the gap between the two ear plates 19 and passes through the second rope lock 221 to be connected to the scraper structure 3. In this way, the operating frame can be retracted on the operating platform by pulling the recovery rope.

[0060] The following describes a method for scraping the mortar on the outer wall of the cylinder section using the wind power tower scraping device provided by the utility model:

[0061] The operator goes from the bottom of the barrel segment along the passage inside the barrel segment to the top of the barrel segment, places the opening of the rotating seat 1 on the top of the barrel segment with the opening facing the top of the barrel segment, and makes the first side arm 12 and the second side arm 13 of the rotating seat 1 both outside the barrel segment;

[0062] The operating part 152 is rotated to screw the screw 150 toward the outer wall of the barrel segment, driving the clamping plate 151 to cooperate with the first side arm 12 to clamp the outer wall of the barrel segment, so that the ball 17 and the first roller 16 on the first side arm 12 abut against the outer wall of the barrel segment;

[0063] The ear plate 19 on the top wall 11 of the rotating base 1 is rotatably connected to the pivot 211 on the first extension arm 21;

[0064] Adjust the nuts 111 (such as Figure 8 As shown), the gap between the cantilever 14 and the first extension arm 21 is increased, so that the first extension arm 21 rotates counterclockwise relative to the ear plate 19, driving the scraper 31 at the bottom end of the second extension arm 22 to swing toward the outer wall of the barrel section until the scraper is close to the joint seam of the barrel section;

[0065] The rotating seat 1 is rotated, and the first roller 16 and the ball 17 are rotated along the outer wall of the cylinder section to scrape off the glue overflowing or dripping on the outer wall of the cylinder section;

[0066] After scraping is completed, the nut 111 on the adjusting rod 212 located above and below the cantilever 14 is adjusted to release the contact of the scraper 31 with the outer wall of the cylinder section;

[0067] Release the connection between the ear plate 19 and the pivot 211, that is, release the connection between the rotating seat 1 and the operating frame 2;

[0068] Pull the recovery rope to retract the operating frame 2;

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
