Description

Technical Field

[0001] This utility model relates to the field of wind power equipment manufacturing technology, specifically a tower painting device. Background Technology

[0002] As a key supporting structure for wind turbine generators and large signal towers, the tower is usually a large hollow cylinder made of multiple sections of high-strength steel plates rolled and welded together. It bears wind force, gravity and complex environmental loads for a long time. In order to achieve its service life of up to decades, it must be protected by strict anti-corrosion coating. At the same time, environmental parameters and construction processes are monitored throughout the process to build a solid barrier against wind, rain, salt spray and ultraviolet radiation.

[0003] When painting a tower, it is usually necessary to place the tower on an auxiliary wheel so that the tower can rotate stably to receive the spray. However, the area where the tower contacts the auxiliary wheel is easily scratched during rotation. Even if a soft rubber wheel is used, it may be damaged due to pressure adhesion before the paint film is completely dry. This makes these contact points the starting point for coating defects and future corrosion. Therefore, a tower painting device is proposed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the area where the tower and auxiliary wheel contact each other being easily scratched during rotation, this invention proposes a tower painting device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tower spraying device, including a workbench, two fixed blocks are fixedly connected to the surface of the workbench, a first bracket is fixedly connected to one side of each of the two fixed blocks, and a support mechanism is provided on the surface of the fixed blocks. The support mechanism includes a sleeve rotatably connected inside a fixed block. Both ends of the sleeve penetrate the fixed block and are rotatably connected to the inner cavity of the fixed block. A second bracket is fixedly fitted onto the surface of the sleeve. A threaded rod is threadedly connected to the inside of the sleeve. One end of the threaded rod is rotatably connected to a sleeve rod. The inner cavity of the sleeve rod is slidably connected to the surface of the sleeve.

One end of each of the connecting rods is rotatably connected to the surface of one of the four support plates. A transmission assembly is provided on the surface of the first bracket. The transmission assembly works in conjunction with the sleeve.

[0006] Preferably, the sleeve rod has a first sliding groove inside, and one end of the threaded rod is fixedly connected to a first slider, the surface of the first slider being slidably connected to the inner cavity of the first sliding groove.

[0007] Preferably, the surface of the sleeve is provided with a second sliding groove, and a second slider is fixedly connected inside the sleeve rod, with the surface of the second slider slidably connected to the inner cavity of the second sliding groove.

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a tower painting device. (Refer to...) Figure 1 and Figure 3 A tower spraying device includes a workbench 1, on the surface of the workbench 1 two fixed blocks 101 are fixedly connected, and a first bracket 102 is fixedly connected to one side of each of the two fixed blocks 101. A support mechanism 2 is provided on the surface of the fixed blocks. The spray head 106 includes a nozzle, a precision needle valve, an atomizing cap and a solenoid valve, etc., which are existing technologies and will not be described in detail here. The support mechanism 2 includes a sleeve 201 rotatably connected inside the fixed block 101. Both ends of the sleeve 201 pass through the fixed block 101 and are rotatably connected to the inner cavity of the fixed block 101. A second bracket 202 is fixedly sleeved on the surface of the sleeve 201. A threaded rod 203 is threadedly connected inside the sleeve 201. One end of the threaded rod 203 is rotatably connected to a sleeve rod 204. The inner cavity of the sleeve rod 204 is slidably connected to the surface of the sleeve 201. Four support plates 205 are slidably connected to the surface of the second bracket 202. Several connecting rods 206 are rotatably connected to the surface of the sleeve rod 204. One end of each connecting rod 206 is rotatably connected to the surface of the four support plates 205. A transmission assembly 3 is provided on the surface of the first bracket 102. The transmission assembly 3 is used in conjunction with the sleeve 201. When the tower needs to be painted, the tower is hoisted between two fixed blocks 101. Then, the threaded rod 203 is rotated, which drives the sleeve rod 204 to move. The sleeve rod 204 pushes the support plate 205 through the connecting rod 206, so that the support plate 205 fits tightly against the inner wall of the tower. After the tower is supported, the sleeve 201 is rotated through the transmission assembly 3. The sleeve 201 drives the second bracket 202 to rotate, so that the second bracket 202 drives the tower to rotate through the support plate 205. This allows the surface of the tower to rotate evenly to receive the paint without contact with any equipment, avoiding the risk of the tower surface being scratched by the auxiliary wheels.

[0018] Reference Figure 3 and Figure 4 The sleeve rod 204 has a first sliding groove 207 inside. One end of the threaded rod 203 is fixedly connected to a first slider 208. The surface of the first slider 208 is slidably connected to the inner cavity of the first sliding groove 207. When the threaded rod 203 is rotated, the stability of the first sliding groove 207 and the first slider 208 allows the rotating threaded rod 203 to drive the sleeve rod 204 to move, and ensures the position of the sleeve rod 204 on the surface of the threaded rod 203, preventing the sleeve rod 204 from separating from the threaded rod 203.

[0019] Reference Figure 3 and Figure 4 The sleeve 201 has a second groove 209 on its surface, and the sleeve rod 204 has a second slider 210 fixedly connected inside. The surface of the second slider 210 is slidably connected to the inner cavity of the second groove 209. When the sleeve rod 204 moves, the stability of the second slider 210 and the second groove 209 ensures the position of the sleeve rod 204 and prevents the sleeve rod 204 from separating from the surface of the sleeve 201.

[0020] Reference Figure 2 and Figure 3The second support 202 has a first limiting groove 211 on its surface. One end of the support plate 205 is fixedly connected to a first limiting block 212. The surface of the first limiting block 212 is slidably connected to the inner cavity of the first limiting groove 211. When the connecting rod 206 pushes the support plate 205, the stability of the first limiting groove 211 and the first limiting block 212 ensures the position of the support plate 205, so that the support plate 205 can only slide up and down, preventing the support plate 205 from separating from the second support 202. The second support 202 can drive the support plate 205 to rotate through the first limiting block 212, thereby causing the support plate 205 to drive the tower to rotate evenly to receive paint.

[0021] Reference Figure 2 and Figure 3 The surface of the fixing block 101 is provided with a second limiting groove 213, and a second limiting block 214 is fixedly connected to one side of the second bracket 202. The surface of the second limiting block 214 is slidably connected to the inner cavity of the second limiting groove 213. When the second bracket 202 rotates, the stability of the second limiting groove 213 and the second limiting block 214 ensures the position of the second bracket 202 and the sleeve 201, and prevents the second bracket 202 and the sleeve 201 from separating from the fixing block 101.

[0022] Reference Figure 1 The transmission assembly 3 includes a motor 301 fixedly mounted on the surface of one of the first brackets 102. A reciprocating screw 103 is rotatably connected inside both first brackets 102. Both ends of the reciprocating screw 103 pass through the first bracket 102 and are rotatably connected to the inner cavity of the first bracket 102. One end of the reciprocating screw 103 is fixedly connected to the output end of the motor 301. A moving block 104 is threaded on the surface of the reciprocating screw 103. A nozzle 105 is fixedly mounted on the surface of the moving block 104. A first synchronous pulley 302 is fixedly mounted on one end of each of the two sleeves 201. A second synchronous pulley 303 is fixedly mounted on both ends of the reciprocating screw 103. A synchronous belt 304 is driven between the surface of the first synchronous pulley 302 and the surface of the second synchronous pulley 303. When it is necessary to rotate the sleeve 201, the motor 103 is started. The motor 103 drives the reciprocating screw 104 to rotate. The reciprocating screw 104 drives the spray head 106 to move back and forth through the moving block 105 to spray paint the tower. When rotating the reciprocating screw 104, the reciprocating screw 104 drives the second synchronous pulley 302 to rotate. The second synchronous pulley 302 drives the first synchronous pulley 301 to rotate through the synchronous belt 303. Thus, the two first synchronous pulleys 301 can drive the sleeve 201 to rotate respectively, so that the two sleeves 201 can drive the two ends of the tower to rotate evenly to receive paint spraying.

[0023] Reference Figure 1Two fixed rods 106 are fixedly connected to the opposite side of the two first brackets 102. The inner cavity of the moving block 104 is slidably sleeved on the surface of the fixed rods 106. When the reciprocating screw 103 rotates, the fixed rods 106 stabilize the moving block 104 so that it can move on the surface of the reciprocating screw 103, thus preventing the moving block 104 from rotating with the reciprocating screw 103.

[0024] Working principle: When the tower needs to be painted, the tower is suspended between two fixed blocks 101. Then, the threaded rod 203 is rotated, causing the threaded rod 203 to drive the sleeve rod 204 to move. The sleeve rod 204 pushes the support plate 205 through the connecting rod 206, so that the surface of the support plate 205 supports the inner wall of the tower. After the tower is supported, the motor 103 is started. The motor 103 drives the reciprocating screw 104 to rotate. The reciprocating screw 104 drives the spray head 10 through the moving block 105. 6. Movement: As the nozzle 106 moves, the reciprocating screw 104 drives the second synchronous pulley 302 to rotate. The second synchronous pulley 302 causes the first synchronous pulley 301 to rotate via the synchronous belt 303. The first synchronous pulley 301 drives the second support 202 to rotate via the sleeve 201, so that the second support 202 drives the tower to rotate via the support plate 205. This allows the surface of the tower to rotate evenly to receive paint without equipment contact, avoiding the risk of the tower surface being scratched by the auxiliary wheel.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
