Description

Technical Field

[0001] This utility model belongs to the field of tower processing technology, specifically relating to a rotating device for tower painting. Background Technology

[0002] To ensure the durability and safety of the tower in complex environments, surface coating protection is a critical process. Currently, the industry commonly uses a coating process that involves rotating the tower itself using a rotating device while simultaneously arranging painting equipment around the outer circumference of the tower to achieve efficient coverage of the cylindrical surface. This operating mode, with its advantages of high automation and fast coating efficiency, is widely used in tower production lines. However, existing tower rotation devices mostly employ a rotation method driven by the tower's center. This design reveals significant flaws when dealing with protruding structures (e.g., multiple prismatic, near-circular structures) that extend along the tower's length for mechanical reinforcement. Because the drive center is fixed, when the protruding part rotates close to the painting structure, the distance between it and the painting equipment is significantly reduced compared to flat areas of the tower, resulting in a surge in paint absorption in those areas. Conversely, recessed areas far from the painting equipment suffer from insufficient paint adhesion due to the excessive distance. Simultaneously, the inability to dynamically adjust the rotation center makes it difficult to maintain a constant distance between the tower's outer perimeter and the painting structure, further exacerbating coating thickness unevenness. This uneven coating not only wastes paint resources but also causes quality problems such as sagging and inconsistent drying due to excessively thick local coatings, while thinner areas fail to form an effective protective layer, increasing the risk of tower surface corrosion and shortening equipment lifespan. Utility Model Content

[0003] To address the problem that existing paint spraying rotary devices cannot dynamically adjust the tower position, this utility model provides a rotary device for tower painting.

[0004] The solution adopted by this utility model to solve its technical problem is: a rotating device for tower painting, including a support frame that can support the painting equipment, the support frame including a horizontally arranged paint-carrying plate and a base, and the paint-carrying plate and the base are connected together by a support column. The paint carrier plate can be horizontally aligned with the paint spray nozzle of the spraying equipment, and the paint carrier plate is provided with a spacer, which includes a screw on the support frame that can roll and press against the surface of the tower. The support column is slidably provided with a support frame supported by a support spring. The support frame can roll to support the tower and adapt to the positional changes of the tower after it is compressed, in conjunction with the support spring.

[0005] Preferably, the support frame is arc-shaped, and both ends of the arc are provided with horizontal parts that slide in cooperation with the bearing column.

[0006] Preferably, the screw is threadedly connected to a threaded cylinder provided on the paint carrier plate.

[0007] Preferably, the screw is provided with ball bearings at the end facing the tower.

[0008] Preferably, a through groove is provided at the center of the support frame, and a driving component for driving the tower to rotate is provided in the through groove.

[0009] Preferably, the driving component includes a plurality of transmission cylinders evenly arranged in the through groove. The transmission cylinders are supported by a rotating shaft rotatably mounted on a support frame, and the rotating shaft at the center is connected to a reducer. The reducer is driven by a drive motor, which is supported by a frame mounted on the support frame.

[0010] Preferably, the support frame is provided with a counterweight on the side opposite to the reducer.

[0011] Preferably, the outer layer of the transmission cylinder is provided with an elastic layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a paint-carrying plate, horizontally aligned with the spray nozzle of the painting equipment, as a platform. A spacer mounted on the paint-carrying plate presses down on the tower, ensuring a consistent distance between the tower and the paint-carrying plate. This function is achieved through a screw and a bolt within the spacer. Furthermore, the spacer works in conjunction with a support frame slidably mounted on a support structure and supported by a spring, adapting to changes in the tower's vertical position after being pressed down by the spacer. This ensures a relatively constant distance between the spray nozzle of the painting equipment and the outer circumference of the tower. Thus, when the painting equipment encounters ridged protrusions on the tower surface, it effectively reduces the probability of over-spraying paint on these protrusions, achieving a certain degree of uniform painting of the tower surface.

[0013] 2. This utility model adjusts the distance between the tower and the paint-carrying plate by setting up a screw and cylinder structure to adapt to different usage scenarios. At the same time, by setting ball bearings at the end of the screw facing the tower, the friction between the screw and the tower surface and the resulting wear are effectively reduced, and it can quickly respond to changes in the protrusions of the tower surface.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1-3 This utility model provides a technical solution for a rotating device for tower painting: according to Figure 1 and Figure 2 As shown, a support frame 1, including the drive unit 4, the support bracket 5, and the painting equipment, provides stable support and rotation for the tower 3 and facilitates the painting operation of the tower 3. The support frame 1 and the support bracket 5 are in sliding engagement, and the support bracket 5 is supported by a lifting spring 7. Figure 3 As shown, multiple support frames 5, under the elastic force of multiple support springs 7 and the physical constraint of the support frame 1, jointly support the tower cylinder 3. The drive component 4 installed on the support frame 5, through its own rotational movement, works in conjunction with the frictional force generated on the surface of the tower cylinder 3 to achieve the rotation of the tower cylinder 3.

[0018] A spacer 2 is installed at the horizontal alignment position between the support frame 1 and the painting equipment. The function of the spacer 2 is to press down on the tower 3 supported by the support frame 5 and overcome the elastic force of the lifting spring, ensuring that the spray nozzle of the painting equipment on the support frame 1 maintains a constant distance from the surface of the rotating tower 3. The design principle is that when the tower 3 is driven to rotate by the drive component 4, the protruding part on its surface is pressed down by the spacer 2, thereby overcoming the elastic force of the lifting spring and causing the tower 3 to produce a slight displacement in the vertical direction, so as to maintain a constant distance between it and the spray nozzle, thus effectively avoiding the problem of uneven paint spraying caused by changes in distance.

[0019] The support frame 1 includes a base 101 and a paint-carrying plate 103 arranged in parallel, which are stably connected by two vertically arranged support columns 102. The support bracket 5 has an arc-shaped design, and both ends are equipped with horizontal blocks that slide with the support columns 102 to achieve smooth sliding of the support bracket 5 on the support frame 1. Support springs are arranged between the support bracket 5 and the base 101 and surround the support columns 102. The positioning of the support springs not only maintains the relative stability of the support springs, but also ensures that the support bracket 5 can be stably and reliably supported.

[0020] To enhance the mobility and flexibility of the support frame 1, rollers with brake positioning structures can be installed at the four corners of the bottom of the support frame 1. This allows operators to easily move the entire support frame 1 system to the required working position and perform precise positioning and fixation.

[0021] The paint carrier plate 103 is designed to achieve precise horizontal alignment with the spray nozzle of the painting equipment. At the center of the paint carrier plate 103, a spacer 2, including a screw barrel 203, is mounted, with a screw rod 202 threadedly connected inside the screw barrel 203. A ball bearing 204 is rotatably mounted at the bottom of the screw rod 202 for contact with the surface of the tower 3. A rotating disk 201 is located at the end of the screw rod 202 away from the ball bearing 204, allowing the operator to drive the screw rod 202 to rotate. The introduction of the ball bearing 204 effectively avoids damage caused by direct contact between the screw rod 202 and the surface of the tower 3, and also ensures that the ball bearing 204 rolls smoothly during the rotation of the tower 3 without obstructing its rotation. More importantly, the ball bearing 204 can quickly detect the prismatic protrusions on the surface of the tower 3 and generate downward displacement by pressing against the tower 3, thereby maintaining a constant distance between the painting equipment and the tower 3. Meanwhile, the threaded connection design between the screw 202 and the screw barrel 203 allows operators to easily adjust the distance between the painting equipment and the tower 3 to accommodate towers 3 with different diameters or surface shapes.

[0022] A through slot 6 is provided at the center of the support frame 5. This through slot 6 is specifically designed to house the driving component 4, ensuring the stable position of the driving component 4 and minimizing its space occupation. The driving component 4 consists of multiple transmission cylinders 401 evenly distributed within the through slot 6. The surface of the transmission cylinders 401 is covered with an elastic layer. This design aims to reduce damage to the surface of the tower cylinder 3 caused by the transmission cylinders 401 during the rotation of the tower cylinder 3, while increasing the contact area between the transmission cylinders 401 and the surface of the tower cylinder 3, thereby increasing the friction between them and reducing the probability of sliding friction.

[0023] The transmission cylinder 401 is supported by a rotating shaft 402 rotatably mounted on the support frame 5. A reducer 404, located on the support frame 5, is connected at the center of the rotating shaft 402. The reducer 404 is driven by a drive motor 405. The drive motor 405 is positioned by a frame 406 mounted on the support frame 5 to ensure the stability and reliability of the entire drive system. A counterweight 403 is fixedly installed on the side of the support frame 5 away from the drive motor 405. This design aims to maintain the balance of the support frame 5 and avoid uneven sliding caused by the support frame 5 deflecting on the support column 102.

[0024] In practical use, the operator first places the tower cylinder 3 onto the corresponding platform, and then connects two or more support brackets 5 to the tower cylinder 3. After connection, the platform is removed, and the support brackets 5 are placed at the locations where the tower cylinder 3 has obvious protrusions. At the same time, the base 101 is fixed to the corresponding ground position using hooks or other structures. After multiple support brackets 5 jointly support the tower cylinder 3, the operator can rotate the corresponding screws 202 one by one through the rotating disk 201, so that the balls 204 press against the surface of the tower cylinder 3 with the cooperation of the screw cylinder 203, thereby ensuring that the paint carrier plate 103 and the surface of the tower cylinder 3 maintain the corresponding distance. Next, the painting equipment, which can be displaced along the length of the tower cylinder 3, is placed on multiple paint carrier plates 103, and the paint carrier plates 103 are aligned horizontally with the spray nozzles of the painting equipment. Finally, multiple drive motors 405 are started in conjunction with reducers 404 to drive multiple corresponding rotating shafts 402 to rotate, which in turn drives the tower cylinder 3 to rotate through multiple transmission cylinders 401. During the rotation of the tower cylinder 3, multiple transmission head cylinders and the rotating shaft 402 provide guidance to maintain rotational stability. After the tower cylinder 3 rotates, the painting equipment can be started to paint the surface of the tower cylinder 3. During the painting process, if any ball bearing 204 senses a protrusion on the surface of the tower cylinder 3, it will press down on the entire tower cylinder 3 to overcome the elastic force of multiple support springs 7, thereby maintaining a constant distance between the protrusion of the tower cylinder 3 and the spray nozzle of the painting equipment. This effectively avoids excessive painting on the protrusion and improves the uniformity of the paint on the surface of the tower cylinder 3. If multiple support frames 1 are set to support the tower cylinder 3, the painting equipment can perform the painting operation of the tower cylinder 3 in sections with the support frames 1 as intervals.

[0025] The specific details regarding how the painting equipment moves along the length of the tower 3, the model of the drive motor 405, the model of the reducer 404, how the drive motor 405 and the reducer motor cooperate to drive the corresponding rotating shaft 402, and the position setting of the support frame 1 should all be understood as existing technology.
