DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the utility model technical scheme will be described clearly and completely below in conjunction with embodiments.

[0023] Embodiment 1: the utility model provides a kind of special device for wind power tower spraying, as shown in figure Figures 1 to 5 Including: tower body 1 and spraying equipment base 2, the top end of spraying equipment base 2 is fixedly installed with control box 21, the bottom end of spraying equipment base 2 is symmetrically installed with several groups of wheels 22, the top end of spraying equipment base 2 is fixedly installed with lifting structure 23 on the side of control box 21, the top end of lifting structure 23 is provided with rotating structure 24, the output shaft outside of rotating structure 24 is fixedly sleeved with telescopic structure 25, the existing spraying equipment is started when using, the operation of each structure is started by pressing the working button at corresponding position on control box 21, the position height of rotating structure 24 and telescopic structure 25 is used for lifting or lowering lifting structure 23 on spraying equipment base 2, for some inner diameter different tower body 1 inner wall operation, the height of rotating structure 24 and telescopic structure 25 is correspondingly raised or lowered, and the length of telescopic structure 25 is adjusted so that the spray head at both ends thereof is about to adhere to the inner wall of tower body 1, so that the paint sprayed by the spray head at both ends of telescopic structure 25 can be evenly and effectively brushed on the inner wall of tower body 1, the above are all prior art, and will not be described here again;

[0024] The two sides of spraying equipment base 2 are symmetrically fixedly installed with fixed shaft 3, the outer side of two fixed shafts 3 is rotatably sleeved with movable rod 4, the same scraper 5 is slidably installed between two movable rods 4, the two sides of scraper 5 are integrally formed with limiting bump 51, the inner side of two movable rods 4 is provided with sliding groove 41 corresponding to the outer side of two limiting bumps 51, and the inner side of spraying equipment base 2 is movably connected with positioning pin 6, and the outer side of positioning pin 6 is attached to the bottom end of one of movable rods 4.

[0025] As shown in Figures 2 to 4 The end outer side of two fixed shafts 3 is fixedly sleeved with limiting ring 7, and the opposite surface of limiting ring 7 and movable rod 4 is attached, which effectively prevents movable rod 4 from slipping off from fixed shaft 3 during rotation, and achieves the purpose of protecting limiting ring 7 during rotation.

[0026] As shown in Figure 2 ​Figure 5 As shown, the inside of the spraying equipment base 2 is slidingly installed with a counterweight 8, the outer surface of the counterweight 8 is fixedly connected with a rope 10 at the center position, the inside of the spraying equipment base 2 is fixedly installed with a driving motor 11, and the other end of the rope 10 is wound on the outside of the output shaft of the driving motor 11. When the motor 11 works, the counterweight 8 can be driven to slide away from the lifting structure 23 by the action of the rope 10. When the lifting structure 23 and the telescopic structure 25 rise, the weight of the equipment can be effectively balanced, the instability caused by the change of the gravity center when the lifting structure 23 rises can be avoided, and thus the stability of the whole equipment operation is improved.

[0027] As shown in Figure 2 and Figure 5 , the other side of the counterweight 8 is fixedly connected with spring telescopic rods 9 in symmetry, the other ends of the two spring telescopic rods 9 are fixedly connected to the inner wall of the spraying equipment base 2. When the counterweight 8 moves away from the lifting structure 23, the spring telescopic rods 9 are stretched. When the lifting structure 23 is lowered to the normal height after use, the counterweight 8 is returned to the original position by the tension of the spring telescopic rods 9, so that the gravity center of the whole equipment returns to the balanced state.

[0028] Working principle: when the device is actually used, the worker carries the spraying device to the inside of the tower body 1, pulls out the positioning pin 6, and then the movable rod 4 and the scraper 5 start to turn to the vertical direction due to their own gravity. When the movable rod 4 is in the vertical state, the lowest point has not yet contacted the inner wall of the tower body 1, and at the same time that the movable rod 4 and the scraper 5 are turned, the scraper 5 slides out from the inside of the movable rod 4 and makes its arc surface contact the inner wall of the tower body 1, so that the movable rod 4 and the scraper 5 are in an inclined state as a whole. Then the spraying equipment starts to work and drives the scraper 5 to move. The scraper 5 pushes away the foreign matter at the moving track of the wheel 22 in advance, and makes the foreign matter gradually slide away from the tower body 1 under the guidance of the scraper 5, so that the moving track of the wheel 22 is not affected by the foreign matter when the device is working, and the spraying work on the inner wall of the tower body 1 is stably carried out.

[0029] When the inner wall of the tower body 1 with a large inner diameter is worked, the existing lifting structure 23 and telescopic structure 25 of the device need to be started, the lifting structure 23 is moved upward, and the paint sprayed by the nozzles at both ends of the telescopic structure 25 can work on the inner wall of the tower body 1. At the same time, the motor 11 is started to work, which drives the counterweight 8 to slide by the action of the rope 10 and makes the counterweight 8 slide away from the lifting structure 23, so that the gravity center of the whole device remains stable. When the lifting structure 23 and the telescopic structure 25 move upward, the change of the gravity center of the whole device does not cause the instability of the device during operation, so that the whole spraying device remains balanced and stable, and the spraying work on the inner wall of the tower body 1 is ensured to be completed.

[0030] The above examples are only used to illustrate the technical solutions of the present application, and are not limiting.
