Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion devices, in particular to a surface anti-corrosion treatment device for boiler steel structure steel components. Background Art

[0002] At present, for the purpose of corrosion protection, organic coatings (such as epoxy resin coatings, polyurethane coatings, etc.) are used to coat the surface of boilers. Organic coatings have good chemical corrosion resistance, wear resistance and other characteristics, and can effectively prevent corrosive media from contacting metal surfaces. As the boiler structure is used, its steel structure needs to be inspected and maintained regularly. At this time, a spray device is needed. The application number is 202023157316.1, which discloses a boiler anti-corrosion and anti-wear spray device, which belongs to the field of industrial boiler technology, including a spray gun, a handle, a switch button and a nozzle. The bottom end of the spray gun is fixedly connected to the handle, and the surface of the handle is fixedly connected to the handle. A switch button is raised on one side of the surface, a nozzle is extended from the front end of the spray gun, and an inner stop ring is raised on the surface of the nozzle body behind the nozzle, the inner stop ring is embedded upward between the rubber inner rings of the rubber tube, and the rubber tube is sleeved on the outside of the nozzle body of the nozzle, the rubber tube is fixedly connected to the rear end of the cover body of the wind shield, and an inner stop ring is provided on the outside of the nozzle at the front end of the spray gun, and the rubber tube behind the wind shield is covered to the outside of the nozzle, so that the rubber inner ring in the rubber tube is fully engaged with the inner stop ring on the surface of the nozzle, thereby completing the fixation of the wind shield and the nozzle. When disassembling, the rubber tube can be directly pulled backward from the surface of the nozzle to complete the disassembly of the wind shield.

[0003] Due to the different heights of the boilers, different spraying angles are required, and the above structure is not convenient to adjust so as to spray the structure at the corresponding required position; Application No. 202023262148.2 discloses a combined boiler anti-corrosion spray device, which belongs to the field of boiler anti-corrosion, including a base, a movable structure is installed at both ends of the base, and the movable structure consists of a rotating block, a rotating shaft, a fixed column, a roller and a limit block. The rotating shaft passes through the base and the fixed column, and a limit block is installed at the bottom of the rotating shaft. A rotating block is installed at the top of the rotating shaft. A fixed column is installed at the bottom of the base, and rollers are installed on both sides of the fixed column. A mixing box is installed above the base, and a power box and a sealing box are installed at the top of the mixing box. A supercharger and a battery are installed inside the power box. A motor is installed in the sealing box, and a vertical shaft is provided through the sealing box. By stirring the preservative, the preservative is prevented from agglomerating, which facilitates spraying of the combined boiler. By adjusting the height of the rotating shaft, the mixing box can be easily fixed and limited, which increases the convenience of the device.

[0004] The above structure still has the problem of being inconvenient to adjust the material output angle and output position, and is relatively inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , a surface anti-corrosion treatment device for boiler steel structure steel components, including a support assembly, a paint spraying assembly and an adjustment assembly, the support assembly includes a base plate 1 and a moving assembly, the moving assembly is provided at the four corners below the base plate 1, the paint spraying assembly includes a liquid supply tank 2, a liquid supply pump 3, a connecting pipe 4 and an output head 5, the liquid supply tank 2 is provided on the base plate 1, the two ends of the liquid supply pump 3 are respectively connected to the liquid supply tank 2 and one end of the connecting pipe 4, the other end of the connecting pipe 4 is connected to the output head 5, the adjustment assembly includes a lifting frame 6, a partition 7, a first motor 8, a screw 9, a turntable 10, a rotating shaft 11, a mounting seat 12 and a lifting plate 13, The lifting frame 6 is arranged on the base plate 1, and a lifting groove is provided at the end of the lifting frame 6 away from the liquid supply box 2. A partition 7 and a screw 9 are provided in the lifting groove. The bottom wall of the partition 7 is provided with the first motor 8. The top wall of the screw 9 is rotatably connected to the top wall of the lifting groove. The bottom wall of the screw 9 passes through the partition 7 and is connected to the first motor 8. The lifting plate 13 extends into the lifting groove and is threadedly connected to the screw 9. A turntable 10 is also provided on the lifting plate 13, and a rotating shaft 11 passing through the lifting plate 13 is also provided below the turntable 10. A mounting seat 12 for mounting the output head 5 is also provided on the turntable 10.

[0025] When the entire anti-corrosion treatment device needs to be moved to a suitable working position, the device is moved by means of universal wheels 14 provided at the four corners below the base plate 1. The universal wheels 14 can flexibly turn, facilitating movement of the device in different directions, allowing it to approach the boiler steel structure steel components that require anti-corrosion treatment. Once the device has been moved to the designated position, the brakes 15 provided on the sides of the universal wheels 14 are operated to generate sufficient friction with the ground, thereby locking the universal wheels 14 and ensuring that the device remains stable during subsequent anti-corrosion treatment operations and prevents accidental movement.

[0026] The liquid supply tank 2 in the painting assembly first stores organic coatings (such as epoxy resin coatings, polyurethane coatings, etc.) used for anti-corrosion treatment of boiler steel structures. The liquid supply pump 3 is activated, and one end of the liquid supply pump 3 is connected to the liquid supply tank 2. Under the action of the liquid supply pump 3, the anti-corrosion coating in the liquid supply tank 2 is extracted and delivered to the output head 5 through the connecting pipe 4. The connecting pipe 4 acts as a bridge connecting the liquid supply pump 3 and the output head 5, ensuring that the anti-corrosion coating can smoothly reach the output head 5 from the liquid supply tank 2, preparing for the subsequent spraying operation.

[0027] When it is necessary to adjust the vertical position of the output head 5 according to the height of different parts of the boiler steel structure, start the first motor 8 in the adjustment assembly. The first motor 8 is set on the bottom wall of the partition 7, and its output end is connected to the bottom wall of the screw 9 after passing through the partition 7. When the first motor 8 rotates, it will drive the screw 9 to rotate in the lifting groove. Because the lifting plate 13 extends into the lifting groove and is threadedly connected to the screw 9, and the lifting plate 13 is limited by the structures such as the partition 7 in the lifting groove, the lifting plate 13 can only move up and down along the axial direction of the screw 9. As the screw 9 rotates, the lifting plate 13 will move up or down according to the direction of motor rotation. For example, when the first motor 8 rotates clockwise, the screw 9 drives the lifting plate 13 to rise; when the first motor 8 rotates counterclockwise, the screw 9 drives the lifting plate 13 to descend. In this way, the turntable 10 installed on the lifting plate 13 and the vertical position of the output head 5 on the turntable 10 can be accurately adjusted to adapt to the parts of the boiler steel structure at different heights, ensuring that the paint can be accurately sprayed to the target position;

[0028] After completing the vertical adjustment, if the angle of the output head 5 on the horizontal plane needs to be adjusted, start the second motor 18 in the adjustment assembly. The second motor 18 is set below the lifting plate 13, and its output end is connected to the worm 20, which is engaged with the worm wheel 19. The rotating shaft 11 passes through the lifting plate 13 below and is connected to the center of the worm wheel 19. When the second motor 18 is started, its output end drives the worm 20 to rotate. Due to the engagement relationship between the worm 20 and the worm wheel 19, the rotation of the worm 20 will drive the worm wheel 19 to rotate. The rotation of the worm wheel 19 in turn drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 will cause the output head 5 installed on the turntable 10 above it to rotate on the horizontal plane together with the turntable 10. By controlling the rotation direction and rotation angle of the second motor 18, the rotation angle of the output head 5 on the horizontal plane can be accurately adjusted to achieve spraying of boiler steel structure steel components at different angle requirements.

[0029] During the process of the turntable 10 driving the output head 5 to adjust the angle, in order to prevent the turntable 10 from excessively rotating (for example, 360-degree rotation may cause problems such as entanglement of components such as the connecting pipe 4), the limit rod 21 arranged on the circumference of the turntable 10 and the limit frame 22 arranged on the lifting plate 13 and adapted to the limit rod 21 play an important limiting role. When the turntable 10 rotates, the limit rod 21 will move within the limit frame 22, and the limit frame 22 limits the moving range of the limit rod 21, thereby limiting the rotation range of the turntable 10, ensuring that the rotation angle of the output head 5 is within a reasonable design range, and avoiding collision or damage between equipment components due to excessive rotation.

[0030] In this embodiment, the top wall of the lifting frame 6 is also provided with a guide assembly for the connecting tube 4 to bundle the wires. The guide assembly includes a roller frame 16 and a guide roller 17. The roller frame 16 is fixed to the top wall of the lifting frame 6. The center of the roller frame 16 is hollow and a guide roller 17 is rotatably provided. An arc groove is provided in the center of the guide roller 17 to prevent the connecting tube 4 from rotating to the output end of the output head 5 and blocking the normal output of the output head 5. The connecting tube 4 is located above the output head 5 under the support of the roller frame 16 and the guide roller 17.
