Description

Technical Field

[0002] A wind turbine tower is a tower for wind power generation, usually made of steel, with the characteristics of high strength and corrosion resistance. A wind turbine tower needs maintenance after long-term use. The maintenance mainly includes appearance inspection, fastener inspection, internal equipment inspection, and anti-corrosion treatment.

[0003] Especially for the maintenance of fasteners such as bolts, including checking whether they are loose and tightening them in time, as well as anti-corrosion treatment to prevent rust due to long-term exposure to the external environment, the traditional maintenance method is to use robots and workers to cooperate. First, the robot detects the tightness and damage of the bolts one by one, and then the workers perform bolt maintenance based on the robot's detection results;

[0004] In order to meet the requirements of structural stability and economy, the shape of a wind turbine tower is usually narrow at the top and wide at the bottom. When the robot walks inside the tower, as the robot rises, the inner diameter of the tower becomes smaller and smaller, and the curvature of the inner wall of the tower becomes larger and larger, which can easily lead to a decrease in the contact area between the robot's tracks or rollers and the inner wall of the tower, causing the robot to deviate and become unstable, thus affecting the bolt maintenance operation.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Example 1: Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 8 The present invention provides a technical solution: a bolt maintenance system for a wind power tower, comprising a first fixing plate 1, a servo motor 11 and a second fixing plate 12, wherein the servo motor 11 is fixedly mounted on the upper surface of the first fixing plate 1, and the second fixing plate 12 is fixedly mounted on the output shaft of the servo motor 11, and a walking assembly is arranged on the second fixing plate 12, wherein the walking assembly comprises a walking module and a balancing module, and the walking module and the balancing module cooperate to realize stable movement of the system;

[0040] The walking module includes a first mounting column 2 fixedly mounted on the bottom of the second fixing plate 12, a second mounting column 21 fixedly mounted on the bottom of the first mounting column 2, first mounting members 22 fixedly mounted on both sides of the first fixing plate 1, a bearing member 23 fixedly mounted on one end of the first mounting member 22 away from the first fixing plate 1, first electric telescopic rods 24 fixedly mounted on both sides of the upper surface of the bearing member 23, a second mounting member 25 mounted on the output shaft of the first electric telescopic rod 24 and the bottom of the second mounting column 21, a second electric telescopic rod 26 fixedly mounted on the surface of the second mounting member 25, a support pad 27 fixedly mounted on the output shaft of the second electric telescopic rod 26, and six second electric telescopic rods 26 are evenly distributed on the outer surface of the second mounting member 25;

[0041] The first electric telescopic rod 24 is fixedly connected to the corresponding second mounting member 25, and the second mounting column 21 is movably connected to the corresponding second mounting member 25;

[0042] The balancing module includes four support columns 28 , which are distributed on both sides of the bearing member 23 , and two on each side;

[0043] A limit block 29 is fixedly installed on one end of the support column 28 away from the bearing member 23, a first return spring 210 is sleeved on the outer surface of the support column 28, a telescopic member 211 is movably installed on the outer surface of the support column 28, and a balance member 212 is fixedly installed on one end of the telescopic member 211 away from the support column 28;

[0044] The diameter of the limit block 29 is larger than the diameter of the support column 28, and a telescopic groove 213 adapted to the limit block 29 is provided inside the telescopic member 211;

[0045] The balance member 212 is arc-shaped. One end of the first return spring 210 is fixedly connected to the bearing member 23 , and the other end is fixedly connected to the telescopic member 211 .

[0046] Specifically, when in use, the system needs to be placed at the center of the tower, and then the lower second electric telescopic rod 26 is started, so that the lower second electric telescopic rod 26 drives the support pad 27 to move and contact the inner wall of the tower, and then the staff needs to buckle their own safety belts in the buckle groove 44;

[0047] Then, it is necessary to start the first electric telescopic rod 24 to drive the upper second mounting member 25 to move upward. After the upper second mounting member 25 moves to the highest stroke, it is necessary to start the upper second electric telescopic rod 26 to make the upper support pad 27 in close contact with the inner wall of the tower, and then start the lower second electric telescopic rod 26 to make the lower support pad 27 separate from the inner wall of the tower. After that, it is necessary to start the first electric telescopic rod 24 again. Since the lower support pad 27 is separated from the inner wall of the tower at this time, under the action of the friction force between the upper support pad 27 and the inner wall of the tower, the first electric telescopic rod 24 will drive the lower second mounting member 25 to rise after it is started again, thereby making the system rise as a whole.

[0048] When the system rises, the lower second electric telescopic rod 26 is started again, so that the lower support pad 27 is in close contact with the inner wall of the tower again, and then the upper second electric telescopic rod 26 is started again, so that the upper support pad 27 is separated from the inner wall of the tower, and then the support pad 27 is started again to drive the upper second mounting member 25 to rise, providing a travel for the system to walk. Such repeated operations can realize the walking of the system, and when the inner diameter of the tower gradually becomes smaller, the stability of the system during walking will not be affected;

[0049] When the system is moving, the staff needs to climb the ladder inside the tower and follow the system. During the movement of the system, under the action of the elastic force of the first return spring 210, the balance member 212 will contact the inner wall of the tower, thereby balancing the system and avoiding the situation in which only one side of the support pad 27 contacts the inner wall of the tower during the movement of the system, causing the system to deflect under the influence of the system's gravity or causing damage to the system due to the stress generated when the system deflects, thereby further improving the stability of the system during movement.

[0050] Example 2: Please refer to Figures 1 to 5 A maintenance assembly is provided on the second mounting column 21, and the maintenance assembly includes an extension arm 3, the extension arm 3 is hinged on the surface of the second mounting column 21, and a spray bin 31 is hinged on one end of the extension arm 3 away from the second mounting column 21, and two extension arms 3 are hinged on the surface of one spray bin 31, and the number of the spray bins 31 is greater than one;

[0051] Blowing bins 32 are fixedly installed on both the upper and lower sides of the spray bin 31, a steel cable 33 is fixedly connected to the surface of the upper blowing bin 32, and a driven ring 34 is fixedly connected to one end of the steel cable 33 away from the blowing bin 32. The driven ring 34 is movably installed on the outer surface of the first mounting column 2, and a third electric telescopic rod 35 is fixedly installed inside the second fixing plate 12, and the driven ring 34 is fixedly connected to the output shaft of the third electric telescopic rod 35;

[0052] The diameter of the second mounting column 21 is greater than that of the first mounting column 2. A second return spring 36 is sleeved on the outer surface of the first mounting column 2. The bottom of the second return spring 36 is fixedly connected to the top of the second mounting column 21. The top of the second return spring 36 is fixedly connected to the driven ring 34.

[0053] The spray bin 31 is concave in shape, a fourth electric telescopic rod 37 is fixedly installed in the depression in the middle of the spray bin 31, a third fixing plate 38 is fixedly installed on the output shaft of the fourth electric telescopic rod 37, an elastic column 39 is bonded to the surface of the third fixing plate 38, a polishing piece 310 is bonded to one end of the elastic column 39 away from the third fixing plate 38, and the number of the elastic column 39 and the polishing piece 310 is greater than one;

[0054] A dust collector 311 is fixedly mounted on the surface of the spray bin 31, and the dust collector 311 is located on one side of the third fixing plate 38;

[0055] A two-way electric telescopic rod 312 is fixedly installed in the depression in the middle of the spray bin 31, and a first piston plate 313 is fixedly installed on the output shaft of the two-way electric telescopic rod 312. Spaces are opened inside the upper and lower ends of the spray bin 31, and the spaces at the upper and lower ends are not connected. The first piston plate 313 is movably installed in the inner space of the blowing bin 32. The first piston plate 313 is fixedly connected to one side of the two-way electric telescopic rod 312 and is fixedly connected to a third return spring 314. One end of the third return spring 314 away from the first piston plate 313 is fixedly connected to the surface of the inner space of the spray bin 31.

[0056] The spray chamber 31 is provided with spray holes 315 on both upper and lower surfaces. The spray holes 315 are inclined toward the vacuum cleaner 311 and are connected to the inner space of the spray chamber 31.

[0057] A piston rod 316 is fixedly mounted on one side of the first piston plate 313 away from the third return spring 314, and a second piston plate 317 is fixedly mounted on one end of the piston rod 316 away from the first piston plate 313. The second piston plate 317 is movably mounted inside the blowing bin 32, and an air outlet groove 318 is provided on the surface of the blowing bin 32, and the air outlet groove 318 is tilted toward the direction of the vacuum cleaner 311.

[0058] A camera mechanism 319 is fixedly installed on the surface of the blowing chamber 32, and a liquid supply box 320 is fixedly installed on the surface of the spray chamber 31. The liquid supply box 320 is in one-way communication with the inner space of the spray chamber 31.

[0059] The four sides of the first piston plate 313 are provided with sealing layers. The piston rod 316 penetrates the spray bin 31 and extends to the inside of the blowing bin 32 . A sealing ring is provided at the movable connection between the piston rod 316 and the spray bin 31 .

[0060] The traditional maintenance system uses robots to tighten bolts. However, after long-term use, the nuts are prone to cracks due to stress. If the bolts are simply tightened, there are still safety hazards.

[0061] On the basis of Example 1, as the system gradually rises, it will contact the flange connection of each section of the tower, which is also the part where the bolts need to be maintained. As the system rises, the balance member 212 will contact the flange, and the flange will squeeze the balance member 212, so that the first return spring 210 is compressed and deformed, providing a stroke for the movement of the balance member 212, so that the balance member 212 bypasses the flange and moves upward with the system, preventing the flange and the balance member 212 from interfering with each other.

[0062] When the position of the third fixing plate 38 is slightly lower than the height of the bolt, it is necessary to start the second electric telescopic rods 26 on the upper and lower sides so that the support pads 27 on the upper and lower sides are in close contact with the inside of the tower to position the system. After the system positioning is completed, it is necessary to start the third electric telescopic rod 35 to drive the driven ring 34 to rise so that the driven ring 34 pulls the steel cable 33 upward. The steel cable 33 can pull the blowing bin 32 upward, and with the cooperation of the expansion arm 3, the spray bin 31 can be expanded outward, and the third fixing plate 38 can be close to the bolt.

[0063] Then, the fourth electric telescopic rod 37 needs to be started to drive the third fixed plate 38 to move, so that the elastic column 39 and the polishing piece 310 can reciprocate, and the bolt is in the moving path of the polishing piece 310. During the reciprocating movement of the polishing piece 310, the bolt and the nut can be polished. Before the polishing process, the vacuum cleaner 311 needs to be started to absorb the rust and dust generated by the polishing to avoid affecting the shooting clarity of the camera mechanism 319;

[0064] The polished bolts and nuts reduce the influence of rust and are easier to observe for cracks. At the same time, during the polishing process, the polishing piece 310 is in constant contact with the nut. The staff can observe whether the nut is shaking or cracked through the display device connected to the camera mechanism 319, thereby improving the maintenance effect.

[0065] When some bolts are polished, the servo motor 11 can be started to drive the first mounting column 2 to rotate, so that the third fixing plate 38 can correspond to the unpolished bolts, thereby completing the polishing of all bolts. It should be noted that in the production process, the spray bins 31 need to be evenly distributed and adapted to the bolt installation spacing of the common tower connection flange after expansion, so as to facilitate the simultaneous operation of multiple spray bins 31 and improve the operation efficiency.

[0066] Furthermore, when the present invention is in use, as the upper end of the tower gradually becomes smaller, the expansion spacing of the spray bin 31 can be changed by starting the third electric telescopic rod 35, so as to adapt to the different inner diameters of the tower at different parts, thereby improving the versatility of the system;

[0067] Furthermore, when the grinding operation is completed, the staff needs to tighten the loose bolts and nuts and replace the cracked bolts and nuts. After the replacement is completed, the two-way electric telescopic rod 312 needs to be started to drive the first piston plate 313 to move, so as to squeeze the anti-rust paint in the internal space of the spray bin 31, so that the anti-rust paint is lightly atomized through the spray hole 315 and then sprayed on the surface of the bolts and nuts, so as to perform anti-rust treatment on the nuts and bolts and increase their service life;

[0068] On the other hand, during the process of spraying the anti-rust paint, in order to prevent the paint from escaping, when the first piston plate 313 moves, it will drive the second piston plate 317 to move, so that the airflow generated during the movement of the second piston plate 317 is blown out through the air outlet slot 318, which can prevent the anti-rust paint from escaping and being wasted, and at the same time, the anti-rust paint mist beads are confined in the space near the bolts and nuts, thereby improving the anti-rust paint spraying effect.

[0069] Example 3: Please refer to Figure 1 , Figure 7 and Figure 8 The first mounting member 22 is provided with a safety assembly, which includes a slide groove 4 provided inside the first mounting member 22, a slider 41 being movably provided in the slide groove 4, a third mounting member 42 being fixedly provided on the surface of the slider 41, a driving block 43 being fixedly provided on one end of the third mounting member 42 away from the slider 41, and a buckle groove 44 being provided in the middle of the third mounting member 42;

[0070] A follower 45 is fixedly mounted on the upper surface of the telescopic member 211. The upper surface of the follower 45 is an inclined surface. The bottom of the driving block 43 is in the shape of an inclined surface that fits the upper surface of the follower 45.

[0071] The shape of the slider 41 is T-shaped, and the shape of the slide groove 4 is T-shaped to match the slider 41 .

[0072] On the basis of Example 1, the staff climbs the ladder and moves up with the system to maintain the bolts. During the climbing process, it is easy to slip and other accidents that may cause the staff to fall. When the staff falls, because their safety rope is buckled in the buckle groove 44, under the influence of its weight, it will drive the third mounting member 42 to move downward, so that the driving block 43 drives the follower 45, and the follower 45 can drive the telescopic member 211 to move, so that the telescopic member 211 drives the balancing member 212 to move and come into close contact with the inner wall of the tower, thereby increasing the friction between the system and the inner wall of the tower, thereby improving the stability of the system, pulling the staff to prevent them from falling, and improving construction safety.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
