Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to an automatic coating production line for wind power generation equipment. Background Technology

[0002] Wind power equipment, especially its cylindrical towers and blades, is exposed to the outdoor environment for extended periods, making it susceptible to corrosion and damage. To improve the equipment's lifespan and safety, regular surface coating operations are necessary to form an anti-corrosion coating. Currently, the coating of wind power equipment is mainly done manually using handheld spray guns at height. This method suffers from low efficiency, limitations in achieving uniformity, and safety hazards.

[0003] Chinese Patent Publication No. CN218655018U discloses an electrostatic powder adaptive spraying device, which can adjust the horizontal and vertical positions of the spray guns, and each spray gun can automatically adjust according to the spraying distance requirements of the product, thereby achieving adaptive spraying. However, this device is mainly suitable for electrostatic powder spraying of general workpieces, and the following technical problems exist when dealing with the coating of large and heavy wind power equipment:

[0004] The above-mentioned spraying devices are mainly moved by manual pushing or motor drive. However, when dealing with large wind power generation equipment, manual pushing is obviously not efficient enough, while the range of movement of motor drive may be limited. Moreover, for the coating of heavy equipment, stronger stability and load-bearing capacity are required.

The first auxiliary roller 81 and the second auxiliary roller 82 roll relative to each other along the upper and lower surfaces of the transverse mounting base 1, respectively; the third auxiliary roller 83 rolls along the front / rear side of the transverse mounting base 1.

[0009] Preferably, the first mounting base 7 is connected to an auxiliary rolling element 11 on its side, which moves laterally along the transverse mounting base 1 together with the first auxiliary roller group 8.

[0010] Preferably, the frame 100 includes a front support frame 13, a rear support frame 14, a left connecting rod 15 connecting the left side of the front support frame 13 and the left side of the rear support frame 14, and a right connecting rod 16 connecting the right side of the front support frame 13 and the right side of the rear support frame 14; the front support frame 13, the rear support frame 14, the left connecting rod 15, and the right connecting rod 16 form an operating space 17 for placing the wind power generation equipment; the front support frame 13 / rear support frame 14 encloses... Includes: multiple uprights 18, reinforcing rods 19 that cross-connect two adjacent uprights 18, and transverse support rods 20 that are transversely connected to the top of the multiple uprights 18; each upright 18 has a protruding mounting seat 21 connected to its front / rear side near the top position, and transverse fixing seats 28 are installed on the multiple protruding mounting seats 21, and the transverse mounting seats 1 are installed on the transverse fixing seats 28; the front support frame 13 and the rear support frame 14 are each equipped with a transverse mounting seat 1, and the longitudinal movable seat 2 is connected between the two transverse mounting seats 1 arranged side by side.

This utility model achieves precise lateral movement of the longitudinal movable seat by using a transverse guide strip and a rack on the transverse mounting base, in conjunction with the drive gear of the first motor. Simultaneously, the rolling of the first auxiliary roller assembly on the surface of the transverse mounting base not only reduces frictional resistance but also further enhances the smoothness and stability of the movement.

The reinforcing base and its triangular support block further disperse the load stress on the transverse fixed base, ensuring the safety of the coating operation. In addition, the high-rigidity support structure helps reduce vibration and deformation during the spraying process, thereby improving the accuracy and quality of the spraying. This stable and safe design enables this utility model to meet the spraying requirements of large-scale wind power generation equipment.

[0017] 3. The spraying mechanism of this utility model adopts a combination of a vertical telescopic rod and a spraying robot, realizing precise coating of different parts of the wind power generation equipment.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown in the figure, the present invention provides an automatic coating production line for wind power equipment. This embodiment provides an automatic coating production line for wind power equipment, used to automatically test the measurement deviation of a human scale when different weights are loaded at the four corners.

[0026] The automatic coating production line for wind power equipment in this case includes:

[0027] The frame 100 is composed of a front support frame 13, a rear support frame 14, a left connecting rod 15, and a right connecting rod 16 welded together to form a cubic frame structure. The middle part is the working space 17, which is used to place the wind power generation equipment to be sprayed.

[0028] Horizontal fixing seat 28: It is fixed to the front support frame 13 and the rear support frame 14 near the top by multiple protruding mounting seats 21. Each protruding mounting seat 21 is connected to the upright 18 by bolts.

[0029] Horizontal mounting bracket 1: Installed on horizontal mounting bracket 28.

[0030] Longitudinal movable seat 2: Installed between two transverse mounting seats 1 arranged side by side, and driven by the first motor 5, the gear 6 meshes with the rack 4 on the transverse guide bar 3 to achieve transverse movement.

[0031] Transverse guide bar 3: welded to the upper surface of the transverse mounting base 1, with a straight rack 4 on its front side, the pitch of which matches the module of the gear 6.

[0032] The first auxiliary roller group 8 includes a first auxiliary roller 81, a second auxiliary roller 82 and a third auxiliary roller 83, which roll along the upper surface, lower surface and front side of the transverse mounting seat 1 respectively to ensure the smooth movement of the longitudinal movable seat 2.

[0033] Specifically, the transverse mounting base 1 has two longitudinal movable seats 2 that move laterally on its left and right sides above it; each transverse mounting base 1 has a transverse guide bar 3 protruding from it, and a rack 4 is provided on the front side of the transverse guide bar 3; in specific implementation, each longitudinal movable seat 2 is equipped with a first motor 5, and the output shaft of each first motor 5 is connected to a gear 6, which meshes with the rack 4 to drive the longitudinal movable seat 2 to move laterally along the transverse guide bar 3; each longitudinal movable seat 2 has a first mounting base 7 on the rear side of the transverse mounting base 1, and each first mounting base 7 is equipped with one or more first auxiliary roller groups 8 that roll along the surface of the transverse mounting base 1; a spraying mechanism 9 is installed on the longitudinal movable seat 2 on the right side.

[0034] As described above, the frame 100 of this invention, through the arrangement of the front support frame, rear support frame, left connecting rod, and right connecting rod, provides a stable and clearly defined working space 200 for the wind power generation equipment, ensuring stability and safety during the coating process and facilitating efficient operation and maintenance of the production line. Simultaneously, the transverse guide strips and racks on each transverse mounting seat, along with the meshing gears and the first motor, enable the longitudinal movable seat to perform precise and stable transverse movement along the transverse guide strips. Furthermore, the rolling of the first auxiliary roller group on the surface of the transverse mounting seat further enhances the smoothness and stability of the movement, allowing the coating mechanism to flexibly adjust its position as needed, thereby providing a greater range of motion and stronger stability, improving coating efficiency, and achieving comprehensive coating of the wind power generation equipment.

[0035] like Figure 3 and Figure 4 As shown, the first mounting base 7 has an L-shaped structure, and a third auxiliary roller 83 is installed in its notch space 10. In specific implementation, the first auxiliary roller 81 and the second auxiliary roller 82 are symmetrically mounted on the upper and lower sides of the first mounting base 7 through bearings, respectively contacting and rolling with the upper and lower surfaces of the transverse mounting base 1. The third auxiliary roller 83 is mounted in the notch space 10 through a vertical rotating shaft, contacting the rear side of the transverse mounting base 1, and restricting the lateral displacement of the longitudinal movable base 2.

[0036] Specifically, when the first motor 5 drives the gear 6 to move along the rack 4, the first auxiliary roller group 8 rolls synchronously, reducing frictional resistance and improving motion accuracy.

[0037] As described above, this invention effectively limits the lateral (upper and lower, front) displacement of the longitudinal movable seat 2 during movement by the coordinated action of the first auxiliary roller 81, the second auxiliary roller 82, and the third auxiliary roller 83 of the first auxiliary roller group 8, further ensuring the stability and accuracy of the movement, and helping to achieve more precise positioning and more efficient spraying operations.

[0038] like Figure 4 As shown, in a specific implementation, the auxiliary rolling element 11 is fixed to the side of the first mounting base 7 by bolts, and the width of its limiting groove 12 is consistent with the thickness of the transverse mounting base 1. The limiting groove 12 can be made of U-shaped steel, with its inner wall conforming to the side of the transverse mounting base 1; thus, the limiting groove 12 plays a certain limiting and guiding role, further enhancing the stability and guiding nature of the longitudinal movable seat, and preventing the longitudinal movable seat 2 from vibrating or shifting during high-speed movement.

[0039] like Figure 5 and Figure 6As shown, in specific implementation, the rear support frame 14 is a truss structure welded from multiple uprights 18 and intersecting reinforcing bars 19, with the top connected by transverse support bars 20 to form a high-rigidity support. The protruding mounting base 21 is welded to the front side of the upright 18 near the top, with multiple protruding mounting bases 21 horizontally aligned to form a horizontal support structure, and a transverse fixing base 28 is welded on it; the transverse mounting base 1 is mounted on the transverse fixing base 28. The front support frame 13 has only two uprights 18 because the rear side bears a greater load, thus saving costs while ensuring stability; specifically, in actual production, it can be designed similarly to the rear support frame 14 according to requirements. Each raised mounting base 21 is also connected to the transverse fixing base 28 via a reinforcing base 22; the reinforcing base 22 includes a fixing block 23, a first triangular support block 24 connected between the bottom surface of the fixing block 23 and the left and right sides of the raised mounting base 21, and a second triangular support block 25 connected between the top surface of the fixing block 23 and the transverse fixing base 28, which are connected by welding to distribute the load stress of the transverse fixing base 28.

[0040] As described above, the arrangement of multiple uprights 18, intersecting reinforcing bars 19, and the first triangular support block 24 and second triangular support block 25 of the reinforcing base 22 further enhances the stability and load-bearing capacity of the frame, improving the overall stability of the production line. This not only meets the painting requirements for wind power equipment or other large equipment but also ensures the safety of the painting operation. Furthermore, the high-rigidity support structure helps reduce vibration and deformation during the painting process, thereby improving the accuracy and quality of the painting.

[0041] like Figure 2 As shown, in a specific implementation, the spraying mechanism 9 includes a vertical telescopic rod 91 and a spraying robot 92. The vertical telescopic rod 91 can be an electric push rod or a hydraulic cylinder, vertically installed on the upper surface of the longitudinal movable seat 2, and can be raised and lowered along the Z-axis. The spraying robot 92 is installed at the bottom of the telescopic rod, equipped with a multi-degree-of-freedom robotic arm and an atomizing nozzle, and the spraying path is controlled by a PLC. In a specific implementation, the longitudinal movable seat 2 moves laterally to the target position, the vertical telescopic rod 91 adjusts the spraying robot 92 to a preset height, and the spraying robot 92 sprays the surface of the wind power generation equipment according to the programmed trajectory.

[0042] As described above, the spraying mechanism in this solution combines a vertical telescopic rod with a spraying robot, enabling precise coating of different parts of the wind power generation equipment. The spraying robot can perform automated coating operations according to a preset program, greatly improving coating efficiency and quality.

[0043] like Figure 3 and Figure 5As shown, in a specific implementation, the transverse fixed seat 28 is connected to limit plates 26 on its left and right sides, and each limit plate 26 is equipped with an elastic buffer member 27 for limiting and buffering. In this way, excessive displacement of the longitudinal movable seat can be prevented, and the elastic buffer member 27 can also reduce wear on the longitudinal movable seat.

[0044] In summary, this utility model achieves efficient and precise automated coating operations, providing strong technical support for the coating of wind power generation equipment.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
