Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical equipment technology, specifically a paint repair device for port machinery. Background Technology
[0002] In ports, due to the long-term exposure of port machinery to the high salt spray and high humidity environment, the paint film on the surface of the steel structure is easily eroded and worn by the sea breeze, resulting in rust spots and coating peeling. At this time, port machinery paint repair equipment is used to spray paint the surface of various large-scale port machinery and equipment (such as cranes, container quay cranes, yard cranes, gantry cranes, oil pipelines, etc.).
[0003] First, the painting equipment needs to be transported to the target position by a mobile device. Then, the painting angle and height are adjusted to paint the mechanical surface. The mobile device is equipped with wheels with ring permanent magnets for driving, which facilitates magnetic adhesion to the mechanical surface.
[0004] Currently, since port machinery is usually a large steel structure, in the process of driving the mobile vehicle to the painting position, the paint will sink due to its own gravity in the traditional single pump paint supply, which will cause the paint to solidify. After the zinc powder in the anti-rust paint settles, the pigment in the topcoat will settle and cause the color concentration to separate. The zinc content of the upper layer of paint is insufficient, resulting in a significant decrease in anti-corrosion performance. Therefore, a paint repair device for port machinery is proposed to address the above problems. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Specific implementation examples are given below.
[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a paint repair device for port machinery, including a mobile vehicle 1; characterized in that: a first motor 11 is fixedly connected to the inner wall of the mobile vehicle 1; a rotating shell 12 is provided at the output end of the first motor 11; an electric push rod 13 is fixedly connected to the inner wall of the rotating shell 12; a receiving plate 14 is fixedly connected to the output end of the electric push rod 13; a telescopic frame 15 is fixedly connected to the side wall of the receiving plate 14; a second motor 16 is fixedly connected to the side wall of the telescopic frame 15; a threaded rod 17 is provided at the output end of the second motor 16; a sliding block 18 is slidably connected to the side wall of the threaded rod 17; and a sliding block 18 is slidably connected to the side wall of the telescopic frame 15. A spray gun assembly 19 is provided on the side wall of the sliding block 18; a spray material storage tank 101 is fixedly connected to the side wall of the mobile vehicle 1; a suction pump 102 is fixedly connected to the side wall of the spray material storage tank 101; a delivery pump 103 is connected through the side wall of the spray material storage tank 101; the suction pump 102 and the delivery pump 103 are connected by a circulation pipe 104; a branch pipe 105 is provided at the output end of the delivery pump 103; multiple sets of nozzles 106 are provided on the side wall of the branch pipe 105; during operation, after the mobile vehicle 1 reaches the target position, the movement position of the sliding block 18 is controlled by starting the second motor 16, and the sliding block is controlled by the electric push rod 13. The height of the spray gun assembly 19 is adjusted to control its height and range. During the movement of the driving vehicle 1 to the target location for painting, the extraction pump 102 is activated to extract paint from the bottom of the spray gun storage tank 101 at a set speed. The paint is then transported to the delivery pump 103 through the circulation pipe 104. The delivery pump 103 receives the paint from the extraction pump 102, pressurizes it, and transports it back into the spray gun storage tank 101. During the return process, the paint is sprayed at high speed through multiple sets of nozzles 106 arranged in different directions on the side wall of the branch pipe 105, thus forming multiple streams inside the spray gun storage tank 101. The jets collide and mix with each other, causing the paint in the storage tank to generate convective motion. At the same time, the speed and conveying direction of the extraction pump 102 and the delivery pump 103 can be adjusted by the external control system to realize various stirring modes such as forward circulation, reverse circulation and intermittent circulation. Thus, the paint can be stirred during the process of moving to the painting position, improving the painting effect. This design solves the problems of easy sedimentation and uneven stirring of traditional single pump paint supply by setting up a dual-pump circulating stirring paint supply system through the coordinated work of the two pumps and the closed loop design. The stirring of the paint by the dual-pump circulating stirring paint supply system can improve the uniformity of the paint and improve the anti-corrosion performance of the paint.
[0029] Furthermore, such as Figure 1 , Figure 5 , Figure 6As shown, an axle 2 is rotatably connected to the inner wall of the mobile vehicle 1; a hub 21 is symmetrically fixed to the side wall of the axle 2; a ring-shaped permanent magnet 22 is fixed to the side wall of the hub 21; a wheel rim 23 is fixed to the side wall of the hub 21; an iron rubber ring 24 is provided on the side wall of the wheel rim 23; multiple sets of connecting frames 25 are fixed to the side wall of the mobile vehicle 1; a vacuum chamber box 26 is fixed to the side wall of the connecting frame 25; a vacuum pump 27 is fixed to the side wall of the vacuum chamber box 26; the output end of the vacuum pump 27 is connected through to the inside of the vacuum chamber box 26; multiple sets of adsorption plates 28 are fixed to the bottom end of the vacuum chamber box 26; during operation, as the mobile vehicle 1 moves to the target location, the ring-shaped permanent magnet 22 can generate a magnetic attraction with the surface of the port machinery, thereby stabilizing the mobile vehicle 1. During the movement of the mobile vehicle on the port machinery, the elastic properties of the iron rubber ring 24 are used to fill the gaps in contact with the machinery surface, improving the fit and enhancing magnetic field coupling. At the same time, the vacuum pump 27 is activated during the movement to create a vacuum effect inside the vacuum chamber 26, and multiple sets of adsorption plates 28 create a vacuum adsorption effect with the machinery surface, thereby improving the adsorption effect between the mobile vehicle 1 and the machinery surface. This design uses the magnetic attraction effect generated by the set ring permanent magnet wheels to make the mobile vehicle 1 attach magnetically to the machinery surface. At the same time, the iron rubber ring fills the gaps between the mobile vehicle 1 and the machinery surface, improving the fit with the surface. In addition, the added vacuum adsorption device can adhere and adsorb to the machinery surface, thereby improving the stability of the mobile vehicle 1 attached to the machinery surface.
[0030] Furthermore, such as Figure 6 As shown, the connecting frame 25 has symmetrical sliding grooves 3 on its sidewalls; spring assemblies 31 are symmetrically fixed to the sidewalls of the sliding grooves 3; and magnet blocks 32 are fixed to the ends of the spring assemblies 31. During operation, when the moving vehicle 1 moves on the mechanical surface, the elasticity of the spring assembly 31 allows the magnet blocks 32 to adaptively adhere to the mechanical surface. The magnetic attraction effect of the magnet blocks 32 enhances the magnetic attraction effect with the mechanical surface. This design, through the adaptive magnet blocks, allows the magnet blocks to adhere to different surfaces of the mechanical surface during the movement of the moving vehicle 1, thereby improving the magnetic attraction effect.
[0031] Furthermore, such as Figure 2As shown, a telescopic adjustment frame 4 is fixedly connected to the side wall of the telescopic frame 15; a telescopic adjustment frame 4 is slidably connected to the side wall of the mobile vehicle 1; a slide rail 41 is fixedly connected to the side wall of the mobile vehicle 1; and a telescopic adjustment frame 4 is slidably connected to the side wall of the slide rail 41. During operation, the first motor 11 can be started to drive the telescopic frame 15 to rotate through the lifting device. At this time, the telescopic adjustment frame 4 provides support for the telescopic frame 15. The telescopic adjustment frame 4 itself has a lifting function, and the rotation trajectory of the telescopic adjustment frame 4 can be limited by the slide rail 41. This design allows the telescopic adjustment frame to automatically adjust according to the rotation of the telescopic frame 15 and to adaptively adjust according to the lifting mechanism, thereby improving the adaptability of the support effect.
[0032] Furthermore, such as Figure 4 As shown, the spray material storage tank 101 is equipped with an anti-vortex baffle 5 inside. During operation, the anti-vortex baffle 5 can reduce the turbulence interference when the paint flows. This design allows the paint to flow more smoothly and orderly during circulation, and the dual-pump circulation stirring system can play a better role.
[0033] Furthermore, such as Figure 4 As shown, a coarse filter screen 6 is fixed to the inner wall of the extraction pump 102. During operation, the paint can be filtered through the coarse filter screen 6. The initial filtration of the coarse filter screen intercepts large particles of impurities, which can effectively reduce the wear of the extraction pump, extend its service life, reduce the frequency of maintenance and replacement, and reduce equipment maintenance costs.
[0034] Furthermore, such as Figure 6 As shown, the sidewall of the magnet block 32 is provided with a rubber sheet 7; during operation, the elastic setting of the rubber sheet 7 can enhance the adhesion with the surface to be operated. This design improves the moving stability of the mobile vehicle 1 by enhancing the adhesion with the surface to be operated.
[0035] Working principle: When the drive vehicle 1 reaches the target position, the second motor 16 is started to control the movement position of the sliding block 18, and the height of the sliding block 18 is controlled by the electric push rod 13. This allows for the adjustment of the working height and range of the spray gun assembly 19. During the movement of the drive vehicle 1 to the target position for painting, the extraction pump 102 is started to extract paint from the bottom of the spray material storage tank 101 at a set speed. The paint is then transported to the delivery pump 103 through the circulation pipe 104. The delivery pump 103 receives the paint from the extraction pump 102, pressurizes it, and transports it back to the spray material storage tank 101. During the return process, multiple sets of nozzles 106 arranged in different directions on the side wall of the branch pipe 105 can spray paint at high speed, thereby forming multiple jets inside the paint storage tank 101. The jets collide and mix with each other, causing the paint in the storage tank to generate convective motion. At the same time, the speed and conveying direction of the extraction pump 102 and the delivery pump 103 can be adjusted by the external control system to realize multiple stirring modes such as forward circulation, reverse circulation and intermittent circulation. Thus, the paint can be stirred during the movement to the painting position, improving the painting effect. During the movement of the mobile vehicle 1 to the target position, through the design... The ring-shaped permanent magnet 22 can magnetically attract the surface of the port machinery, thus enabling the mobile vehicle 1 to move stably on the machinery. During this process, the elastic properties of the iron rubber ring 24 are used to fill the gaps in contact with the machinery surface, improving the fit and enhancing magnetic field coupling. Simultaneously, during movement, the vacuum pump 27 creates a vacuum inside the vacuum chamber 26, and multiple sets of adsorption plates 28 create a vacuum adsorption effect on the machinery surface, thereby improving the adsorption effect between the mobile vehicle 1 and the machinery surface. As the mobile vehicle 1 moves on the machinery surface, the elasticity of the spring assembly 31 allows the magnet 3 to... 2. Adaptive bonding to the mechanical surface. The magnetic attraction effect of the magnet block 32 can enhance the magnetic attraction effect with the mechanical surface. By starting the first motor 11, the telescopic frame 15 can be rotated through the lifting device. At this time, the telescopic adjustment frame 4 provides support for the telescopic frame 15. At the same time, the telescopic adjustment frame 4 itself has a lifting function. The rotation trajectory of the telescopic adjustment frame 4 can be limited by the set slide rail 41. The anti-eddy current baffle 5 can reduce the turbulence interference when the paint flows. The coarse filter screen 6 can filter the paint. The elastic setting of the rubber sheet 7 can enhance the bonding with the surface.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
