Description

Technical Field

[0001] This invention relates to a spraying device and method for applying anti-corrosion coating to the surface of steel in steel structure workshops, belonging to the technical field of steel structure spraying devices. Background Technology

[0002] Before constructing a steel structure factory building, the surfaces of various prefabricated steel components need to be coated with anti-corrosion material. The common method is manual spraying using pneumatic spray guns. However, this requires hoisting the steel components, which necessitates securing them with steel ropes. This results in incomplete coating at the roped areas, requiring re-spraying, which is time-consuming and labor-intensive. Furthermore, the irregular rotation of the steel components after hoisting increases the difficulty of alignment during manual spraying, leading to inconsistent coating thickness. Additionally, manual spraying poses a risk of injury to workers. To address these shortcomings, this invention proposes an anti-corrosion coating device and method for steel structures used in factory buildings. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a spraying device and method for anti-corrosion coating on the surface of steel in steel structure workshops, so as to solve the existing problems.

Multiple pull-down openings are arranged in a circular array on the pressure plate, each aligned with the slide opening of the buffer rod. The diameter of the magnetic base plate is larger than the inner diameter of the pull-down openings.

[0008] A further improvement is that the magnetic pull-down mechanism includes a first telescopic member, on the top surface of which a pull-down plate is arranged laterally. The top surface of the pull-down plate is arranged in a circular array with multiple electromagnetic buffers passing through the pull-down opening. The outer diameter of the electromagnetic buffers is smaller than the inner diameter of the pull-down opening. Each of the electromagnetic buffer components consists of a pull-down column and a positioning inner rod buffer assembly. The top surface of the positioning inner rod is provided with an electromagnetic chuck that electromagnetically attracts the bottom surface of the magnetic base plate.

[0009] A further improvement is that the pull-down column includes a column body, a pull-down sliding cavity is provided in the middle of the top surface of the column body, a positioning tie beam is provided in the lower opening of the pull-down sliding cavity, and a movable through-hole is provided in the middle of the positioning tie beam; The positioning inner rod includes an inner pull rod body fitted onto the upper end of the pull-down sliding cavity. A second spring is fitted onto the rod body of the inner pull rod body. A positioning pull post passing through the movable through-hole is connected to the lower end of the inner pull rod body.

A driven rotating shaft for fixing the driven clamp and a second rotating disk are fitted in the middle of the bottom surface of the beam body. A lead screw sleeve is provided at the right end of the bottom surface of the beam body.

[0011] A further improvement is that the spraying mechanism includes a vertical rail, on which a servo slider is mounted, and a third telescopic device is horizontally arranged on the servo slider. A spraying head is arranged at the right end of the third telescopic device, and a pressurized material tank is connected to the spraying head through a material pipe. The spray head includes a transverse base, on which a second rotator is mounted. A spray gun is drivenly connected to the second rotator. A spacing sensor and a camera are respectively mounted on the transverse base on the side of the spray gun.

[0012] A further improvement is that the flat lifting frame includes a pusher frame, a second telescopic device, a lifting support platform and a stabilizing slide bar are provided in the middle of the pusher frame, a plurality of arc-shaped roller grooves are spaced apart on the top surface of the lifting support platform, and a rolling column is placed in each of the arc-shaped roller grooves, and an infrared sensor is provided on the left side of the lifting support platform.

[0014] Furthermore, this invention also provides a spraying method for the above-mentioned anti-corrosion coating device for steel surfaces in steel structure workshops, the spraying method being as follows: First, the main body of the tilting frame is moved to the left out of the main body of the spray drying oven via the transverse frame and drive slide on the track. The tilting frame body is tilted to the left so that the left end of the tilting frame body is placed against the support seat in a horizontal state. Then, the steel component is lifted horizontally onto the top surface of the horizontal lifting frame by the hoisting equipment and adjusted. Then, the second telescopic device drives the lifting support platform to rise. After the alignment infrared sensor, the steel component is positioned between the driven clamp and the clamp assembly.

[0015] Then the lifting mechanism drives the driven clamp to move laterally towards the clamp assembly, pushing the steel component onto each roller. During the pushing process, the buffer pressure head that forms a pressure against the left and right sides of the steel component retracts, thus forming a pressure groove on each side.

[0016] Then the lifting frame is lowered and reset. At this time, the steel component will be horizontally hooked between the two pressure grooves and will not fall. Then the main body of the flipping frame flips to the right and stands upright. After the steel component is upright, the magnetic pull-down mechanism first establishes electromagnetic attraction with each buffer pressure head and pulls it down, pulling down and retracting the buffer pressure heads that are not pressed down, so that the two pressure grooves are canceled.

[0017] Then the horizontal moving frame is pushed vertically into the main body of the spraying and drying chamber. Then the spraying mechanism performs vertical lifting and lowering to spray the steel components. The driven clamp and clamp assembly cooperate to assist the axial rotation of the steel components that are pressed against the plane to complete the spraying operation.

[0018] The beneficial effects of this invention are: This invention provides a coating device and method for anti-corrosion coating of steel materials in steel structure workshops. The device comprises a coating drying chamber, a coating device, a horizontal lifting frame, and an operation display panel. The horizontal lifting frame assists in the horizontal lifting and pushing of the steel components, while the tilting frame on the coating device assists in the horizontal and vertical turning of the steel components. The sliding cooperation between the drive clamp and the lifting mechanism, which drives the driven clamp, applies pressure to the tail of the steel component, forming two pressure points. The groove clamping prevents the steel components from falling off when the main body of the flipping frame is flipped horizontally or vertically. The drive clamp and driven clamp also have the function of canceling the two temporary auxiliary pressure grooves after the steel component is upright against the two pressure grooves. This allows the spraying mechanism to spray the side surfaces of the steel component in place when it lifts and slides to spray the surface of the steel component, without the problem of spraying dead corners due to the presence of pressure grooves. In addition, the drive clamp and driven clamp also have the function of driving the steel component to rotate axially. In conjunction with the lifting and displacement spraying of the spraying mechanism, the spraying of the steel component is more comprehensive. Attached Figure Description

A spacing sensor 2844 and a camera 2845 are respectively installed on the transverse base 2841 on the side of the spray gun 2843.

[0029] The flat lifting frame 4 includes a pusher frame 41. The pusher frame 41 is provided with a second telescopic device 42, a lifting support platform 43 and a stabilizing slide bar 44 in the middle. The top surface of the lifting support platform 43 is provided with multiple arc-shaped roller grooves 45 at intervals. Each arc-shaped roller groove 45 is filled with a rolling column 46. An infrared sensor 47 is provided on the left side of the lifting support platform 43.

[0030] Working principle: First, the main body 24 of the tilting frame is moved to the left out of the main body 1 of the spray drying room via the transverse frame 21 and the drive slide 22 on the track 23. The tilting frame 24 is tilted to the left so that the left end of the tilting frame 24 rests on the support seat 3 in a horizontal state. Then, the steel component is lifted horizontally onto the top surface of the horizontal lifting frame 4 by the hoisting equipment and adjusted. Then, the second telescopic device 42 drives the lifting support platform 43 to rise. After the alignment infrared sensing of the infrared sensor 47, the steel component is positioned between the driven clamp 27 and the clamp assembly 252.

[0031] The flipping of the main body 24 of the flipping frame is a conventional technology, which will not be described in detail here. The support seat 3 is used to support the left end of the main body 24 of the flipping frame. Since the left end of the main body 24 of the flipping frame is relatively long, it will be biased and needs to be supported to prevent it from flipping to the left on its own. When the infrared sensor 47 detects the lower edge of the driven clamp 27 during the rising process, it can make the steel component rise to the middle area of ​​the driven clamp 27, which is convenient for the alignment and pressure of each buffer pressure head 256.

[0032] Then the lifting mechanism 26 drives the driven clamp 27 to move laterally towards the clamp assembly 252, pushing the steel component onto each of the rolling columns 46. During the pushing process, the buffer pressure head 256 that forms a pressure against the left and right sides of the steel component retracts, thereby forming a pressure groove on each side.

[0033] The lifting mechanism 26 is raised and lowered by the servo motor 264 driving the lead screw 263 to rotate in both directions, which in turn pulls the lifting beam assembly 262 to rise and fall vertically on the two lifting slide rails 261.

[0034] When the steel component presses against the buffer head 256, the first spring 2563 and the second spring 25852 are both compressed to prevent the magnetic base plate 2564 from getting stuck when it descends to press against the electromagnetic chuck 2586.

[0035] Each buffer head 256 corresponds to a retracted pressure groove, which allows the tail of the steel component to be locked in the groove edge, preventing it from falling off when the main body 24 of the tilting frame is tilted vertically.

[0036] When the magnetic base plate 2564 descends and presses against the upper edge of the pull-down opening 2575, it will press down on the pressure plate 2571. After the pressure sensing seat 2754 senses the limited pressure value, it can confirm that the pressure is in place, so that the steel component will not shake between the two pressure grooves.

[0037] Then the lifting frame 4 is lowered and reset. At this time, the steel component will be horizontally hooked between the two pressure grooves and will not fall. Then the main body of the flipping frame 24 flips to the right and stands upright. After the steel component is upright, the magnetic pull-down mechanism 258 first establishes electromagnetic attraction with each buffer pressure head 256 and pulls down, pulling down and retracting the buffer pressure head 256 that is not pressed, so that the two pressure grooves are canceled.

[0038] When the magnetic pull-down mechanism 258 pulls down the unpressed buffer head 256, the electromagnetic chuck 2586 first strongly electromagnetically attracts the magnetic base plate 2564. Then, the first telescopic device 2581 pulls the pull-down plate 2582 down vertically. At this time, the card plate 25854 will be stuck at the lower edge of the movable through-hole 25844 and subjected to force, so that the first spring 2563 and the second spring 25852 are both compressed, allowing the buffer head 256 to descend, thereby achieving the purpose of canceling the pressing groove. It should be noted that the magnetic attraction strength of the electromagnetic chuck 2586 to the magnetic base plate 2564 must be greater than the sum of the compression strength of the first spring 2563 and the second spring 25852 to prevent the electromagnetic attraction from detaching.

[0039] In addition, after the steel components are erected, the purpose of removing the pressure groove is to facilitate the spray gun 2843 to spray the upper and lower edges of the steel components, and to prevent the pressure groove from having a recessed opening that cannot be sprayed properly.

[0040] Then the transverse frame 21 is pushed vertically into the main body 1 of the spraying and drying chamber, and the spraying mechanism 28 performs vertical lifting and lowering to spray the steel components. The driven clamp 27 and the clamp assembly 252 cooperate to assist the axial rotation of the steel components that are pressed against the plane, thus completing the spraying operation.

[0041] The spraying mechanism 28 adopts lifting displacement spraying, while the cooperation of the third telescopic device 283 and the spacing sensor 2844 can adjust the distance between the spray gun 2843 and the surface of the steel component. The second rotator 2842 can drive the spray gun 2843 to turn, making it easier to align with the surface of the steel component. The camera 2845 is used for scanning during the spraying process, which makes it easier for the staff to observe on the operation display panel 5.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Then, the steel component is lifted horizontally onto the top surface of the flat lifting frame by the hoisting equipment and adjusted. Then, the second telescopic device drives the lifting support platform to rise. After the alignment infrared sensor, the steel component is positioned between the driven clamp and the clamp assembly. Then the lifting mechanism drives the driven clamp to move laterally towards the clamp assembly, pushing the steel component onto each roller column. During the pushing process, the buffer pressure head that forms a pressure against the left and right sides of the steel component retracts, thus forming a pressure groove on each side. Then the lifting frame is lowered and reset. At this time, the steel component will be horizontally hooked between the two pressure grooves and will not fall. Then the main body of the flipping frame flips to the right and stands upright. After the steel component is upright, the magnetic pull-down mechanism first establishes electromagnetic attraction with each buffer pressure head and pulls it down, pulling down and retracting the buffer pressure heads that are not pressed down, so that the two pressure grooves are canceled. Then the horizontal moving frame is pushed vertically into the main body of the spraying and drying chamber. Then the spraying mechanism performs vertical lifting and lowering to spray the steel components. The driven clamp and clamp assembly cooperate to assist the axial rotation of the steel components that are pressed against the plane to complete the spraying operation.
