TECHNICAL FIELD
[0001] The utility model relates to a kind of wind turbine construction equipment, specifically a kind of wind power tower slurry scraper. BACKGROUND
[0002] Wind power tower is the tower pole of wind turbine, mainly to support wind turbine and absorb wind turbine vibration.
[0003] At present, the wind power tower mainly used is assembly type concrete tower, and the construction can be completed by only splicing and assembling the prefabricated tower sections. In the installation process of the assembly type concrete tower, the tower sections are connected by laying cement base slurry or epoxy base slurry. To ensure the compactness of the horizontal joint base slurry, the thickness of the base slurry needs to be higher than the height of the iron pad. After the upper and lower tower sections are settled, the excess base slurry will be squeezed out. The slurry overflowing into the tower will interfere with the subsequent installation. Therefore, the slurry overflowing from the inside is removed during construction, while the slurry overflowing from the outside is not treated.
[0004] When removing the slurry overflowing from the inside, the method commonly used at present is that workers hold ordinary spades to remove the slurry. The blade of the ordinary spade is usually small and has no curvature. Workers need to repeatedly scrape the slurry on the inner wall of the tower with curvature to completely remove the overflowing slurry, which is low in efficiency. Moreover, the slurry dries quickly. If it is not removed in time, the slurry will solidify on the tower, which makes it impossible for workers to remove the slurry. Therefore, additional mechanical equipment is needed to remove the solidified slurry, which not only wastes construction cost but also is low in efficiency. In addition, the slurry overflowing from the outside of the tower will not affect the subsequent installation, but will seriously affect the appearance. SUMMARY

[0034] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0035] This embodiment discloses a slurry scraper for wind turbine towers, such as... Figure 1 As shown, it includes a blade holder 1, a scraper 2, an adjustment assembly 3, and a handle assembly 4.
[0036] like Figure 2 As shown, the tool holder 1 includes a hollow cross brace 11, a central brace 12, a first diagonal brace 13, and a second diagonal brace 14. The first end of the central brace 12 is vertically fixed at the center of the cross brace 11. The first diagonal brace 13 and the second diagonal brace 14 are symmetrically arranged on both sides of the central brace 12, and their ends are fixed to the cross brace 11 and the central brace 12, respectively. A connecting bolt for connecting to the handle assembly 4 is also fixed at the middle position of the central brace 12.
[0037] The scraper 2 is fixed to the second end of the central support 12. The second end of the central support 12 is located at the center of the scraper 2. The scraper 2 is made of an elastic material; in this embodiment, the material of the scraper 2 is spring steel.
[0038] The adjustment assembly 3 includes a first adjustment component and a second adjustment component, which are symmetrically arranged on both sides of the central support 12 and parallel to the central support 12. The first and second adjustment components are located near the two ends of the cross support 11. The first adjustment component includes a first connecting seat 31 fixed on the cross support 11, a second connecting seat 38 fixed on the scraper 2, and a telescopic rod mechanism whose two ends are rotatably connected to the first connecting seat 31 and the second connecting seat 38, respectively. In this embodiment, the first connecting seat 31 is a connecting ear plate, the second connecting seat 38 is a ball head seat, and the telescopic rod mechanism includes an adjustment sleeve 33, an adjustment screw 34, an adjustment nut 35, and a ball head 36. One end of the adjustment sleeve 33 is rotatably connected to the connecting ear plate through a connecting pin 32, and the other end is threadedly connected to the adjustment screw 34. The adjustment nut 35 is threadedly connected to the adjustment screw 34, and the ball head 36 is fixed on the end of the adjustment screw 34 away from the adjustment sleeve 33. The ball head 36 is installed in the ball head seat through an internal expansion clamp 37. The structure of the second adjusting member is the same as that of the first adjusting member.
[0039] In practical use, the distance from which the adjusting screw 34 extends into the adjusting sleeve 33 is changed by rotating the adjusting screw 34, thereby altering the overall length of the first and second adjusting components. This causes the scraper 2 to be either lifted or pulled back at both ends, thus changing the curvature of the scraper 2. Specifically, when scraping slurry onto the outer surface of the tower, the lengths of the first and second adjusting components need to be increased to lift the scraper 2 at both ends. Once the curvature of the scraper 2 matches the curvature of the outer surface of the tower, the adjusting nut 35 is tightened to press against the adjusting sleeve 33, fixing the lengths of the first and second adjusting components. Slurry scraping can then begin. Similarly, when scraping slurry onto the inner surface of the tower, the lengths of the first and second adjusting components are adjusted accordingly.
[0040] like Figure 4 As shown, the handle assembly 4 includes a top rod 42, at least one intermediate rod 45, and a bottom rod 46 arranged sequentially with decreasing diameters, as well as a limiting mechanism. In this embodiment, there is one intermediate rod 45, which passes through the top rod 42. The bottom rod 46 passes through the intermediate rod 45, and the end of the bottom rod 46 away from the intermediate rod 45 is threaded onto a connecting bolt. A first clamp 43 is fixedly fitted at the bottom of the top rod 42, and a handle 41 is fixedly fitted at the top of the top rod 42. A second clamp 48 is fixedly fitted at the bottom of the intermediate rod 45. The diameter of the end of the first clamp 43 away from the top rod 42 is the same as the diameter of the intermediate rod 45, and the diameter of the end of the second clamp 48 away from the intermediate rod 45 is the same as the diameter of the bottom rod 46. Two limiting mechanisms with identical structures are provided: a first limiting mechanism 44 and a second limiting mechanism 47. The first limiting mechanism 44 is located at the top of the intermediate rod 45, and the second limiting mechanism 47 is located at the top of the bottom rod 46. Figure 5As shown, the first limiting mechanism 44 comprises a connecting head 444 fixed at the end of the middle rod 45, a fixing nut 443 fixed on the connecting head 444, a fixing screw 441 fixed on the connecting head 444 through the fixing nut 443, and an expansion head 442 screwed on the fixing screw 441.
[0041] It is to be noted that, in the unexpanded state of the expansion head 442 of the first limiting mechanism 44, the diameter of the expansion head 442 is greater than the outer diameter of the top rod 42, and the expansion head 442 clamped in the top rod 42 will generate a certain frictional damping with the inner wall of the top rod 42, but will not affect the movement of the expansion head 442 in the top rod 42. Rotating the middle rod 45, since the frictional damping between the fixing screw 441 and the expansion head 442 is smaller than the frictional damping between the expansion head 442 and the inner wall of the top rod 42, the expansion head 442 will not rotate, and the fixing screw 441 will rotate and screw into the expansion head 442 under the driving of the middle rod 45, so that the expansion head 442 expands circumferentially and is fixed in the top rod 42. Reverse rotation of the middle rod 45 will cause the fixing screw 441 to unscrew from the expansion head 442, so that the expansion head 442 returns to the initial state to release the fixation. The structure and working principle of the second limiting mechanism 47 are the same as those of the first limiting mechanism 44. In actual use, only the positions of the various tubes in the handle assembly 4 need to be adjusted, and after the length of the handle assembly 4 reaches the required length, the middle rod 45 and the bottom rod 46 are rotated to fix their positions, and then the use can begin. When the use is completed, the middle rod 45 and the bottom rod 46 are reversed to release the fixed state, so that they can be retracted into the top rod 42. It is to be further noted that the expansion head 442 in this embodiment is a conventional expansion head structure with an open top, and the fixing screw 441 is a conventional bolt with a tapered head at the top. When the fixing screw 441 is screwed into the expansion head 442, the tapered head of the fixing screw 441 will expand the top of the expansion head 442. When the fixing screw 441 is unscrewed from the expansion head 442, the expansion head 442 will return to the initial state due to the loss of support from the tapered head.
[0042] When using this embodiment, first, the curvature of the scraper 2 needs to be adjusted to be the same as that of the tower drum wall, and then the length of the handle assembly 4 is adjusted, and then the scraping of the overflowed slurry can begin. After scraping the tower drum on one side, the curvature of the scraper 2 is adjusted to adapt to the tower drum wall on the other side, and then the scraping of the overflowed slurry on the other side can begin.
[0043] It should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the above embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
