Description

Technical Field

[0001] The present invention relates to the technical field of coating devices, and particularly to a corrosion-resistant coating device for H-shaped steel. Background Art

[0002] H-shaped steel is a long steel bar with an "H"-shaped cross-section, composed of a web (vertical part) and flanges (horizontal parts). It has a large cross-sectional moment of inertia, strong bending / compressive resistance, and light weight, and is a core load-bearing component in fields such as construction, bridges, and machinery. H-shaped steel will corrode in some environments, resulting in a decline in mechanical properties and even structural failure. Therefore, a protective film needs to be coated on the H-shaped steel.

[0003] In the manufacturing and design of H-shaped steel, chamfers need to be provided at the connection between the web and the flange. The chamfers can eliminate stress concentration at the right-angle transition, improve fatigue resistance and load-bearing capacity, especially in dynamic loads (such as bridges and crane girders). However, when spraying the chamfers, the spray gun needs to be at a 45° angle to two adjacent surfaces, that is, the spray gun is perpendicular to the chamfer, to avoid uneven coating thickness on one side due to angle deviation. Moreover, the chamfer lengths of H-shaped steels with different widths are different. Therefore, spraying optimization needs to be carried out according to the chamfer lengths of different H-shaped steels. Summary of the Invention

Detailed implementation manners

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1, as Figures 1 to 2 shown, a corrosion-resistant coating device for H-shaped steel proposed by the present invention includes a frame 1 and a guide rail component 101 fixedly installed on the frame 1. A chassis 102 is slidably installed on the guide rail component 101. The guide rail component 101 can drive the chassis 102 to move along the guide rail component 101. An H-shaped steel 2 is installed on the frame 1. A chamfer 201 is provided on the H-shaped steel 2. The chamfer 201 is 45°. The chamfer 201 can eliminate stress concentration at the right-angle transition and improve fatigue resistance and load-bearing capacity.

[0020] As Figures 2 to 7 and Figure 14As shown in the figure, this embodiment further includes a web spraying component 3 installed inside the chassis 102. The web spraying component 3 includes a plurality of connecting blocks 301. A web spray head assembly 302 is detachably installed on the connecting block 301. The web spraying component 3 further includes an equidistant adjustment mechanism, a contraction mechanism, and a spacing adjustment component. The equidistant adjustment mechanism controls the spacing between adjacent two connecting blocks 301 and makes multiple groups of spacings always remain equal. The contraction mechanism synchronously controls the spraying ranges of multiple groups of web spray head assemblies 302. The spacing adjustment component includes controlling the distance between the web spray head assembly 302 and the H-shaped steel 2. The spraying range of the web spray head assembly 302 depends on the opening angle of the web spray head assembly 302 on the one hand and the distance between the web spray head assembly 302 and the surface of the H-shaped steel 2 on the other hand. By the mutual cooperation of the collection mechanism and the spacing adjustment mechanism, the effective spraying range of the web spray head assembly 302 can be controlled. When the spraying range of the web spray head assembly 302 changes, in order to prevent a spraying blank area from appearing between adjacent two web spray head assemblies 302, it is necessary to adjust the spacing mechanical energy between adjacent two spraying assemblies 302 through the equidistant adjustment mechanism. Therefore, it can effectively adapt to H-shaped steels 2 with different widths.

[0021] It should be noted that the closer the web spray head assembly 302 is to the H-shaped steel 2, the smaller the diffusion range of the sprayed material, and the more accurate the spraying range. Therefore, during spraying, the web spray head assembly 302 can be inserted into the H-shaped steel 2 to make the web spray head assembly 302 fit on the web, which can effectively improve the spraying accuracy range and facilitate the accurate control of the spraying thickness. However, a large number of web spray head assemblies 302 will not be able to enter the H-shaped steel 2 with a small width, and a large number of web spray head assemblies 302 will not be able to effectively fill the entire web, resulting in the need for multiple round-trip spraying operations. Therefore, according to the width of the web, it is extremely important to quickly adjust the number, spacing, and spraying range of the web spray head assemblies 302 uniformly. The above-mentioned equidistant adjustment mechanism, contraction mechanism, and spacing adjustment component can effectively solve this problem.

[0022] Furthermore, the equidistant adjustment mechanism includes a support frame 303 slidably mounted inside the chassis 102. A drive plate 306 is slidably mounted inside the support frame 303, and a first push rod motor 305 is fixedly mounted. The output shaft of the first push rod motor 305 is fixedly connected to the drive plate 306. A slideway 307 is fixedly mounted on the support frame 303. One of the connecting blocks 301 located in the middle is fixedly mounted inside the slideway 307, and the remaining connecting blocks 301 are slidably connected to the slideway 307. Connecting rods 308 are rotatably mounted on both sides of the connecting block 301, and the inclination angles of the connecting rods 308 on both sides are opposite. A plurality of sliders 324 are slidably mounted inside the drive plate 306, and the sliders 324 are rotatably connected to two adjacent connecting rods 308. Under the action of the first push rod motor 305, the drive plate 306 can be driven to move up and down, thereby driving multiple connecting rods 308 to rotate synchronously, and enabling the sliders 324 to slide, which can drive the connecting blocks 301 to move synchronously, and can ensure that the distance between any two connecting blocks 301 remains equal. Therefore, the distance between the web nozzle assemblies 302 connected to the connecting blocks 301 can be adjusted quickly.

[0023] Among them, a connecting rod 309 is detachably mounted on the connecting block 301, and a first mixing tank 310 is fixedly mounted on the connecting rod 309. The web nozzle assembly 302 is fixedly connected to the first mixing tank 310. The web nozzle assembly can be disassembled or installed according to the width of the web, and it can be ensured that the installed web nozzle assembly 302 can move synchronously with the other web nozzle assemblies. The web nozzle assembly 302 includes a housing 3021 fixedly mounted on the first mixing tank 310 and an adjusting plate 3022 rotatably mounted on the housing 3021. By rotating the adjusting plate 3022, the angle between the two adjusting plates 3022 can be changed, and thus the spraying range of the web nozzle assembly 302 can be adjusted. The side of the adjusting plate 3022 can slide relative to the side of the housing 3021, and has a certain sealing property.

[0024] Still further, the contraction mechanism includes an extension rod 311 fixedly mounted on the adjusting plate 3022. A swing rod 312 is rotatably mounted on the extension rod 311. The two swing rods 312 are rotatably connected through a connecting seat 313. The connecting seat 313 is slidably connected to the first mixing tank 310 through a round rod 314. A second push rod motor 315 is fixedly mounted on one of the first mixing tanks 310. The output shaft of the second push rod motor 315 is fixedly connected to the connecting seat 313. Adjacent connecting seats 313 are fixedly connected through a connecting member. By the second push rod motor 315, the connecting seat 313 can be driven to move up and down, and the swing rods 312 on both sides can be driven to rotate through the connecting seat 313. The rotating swing rods 312 will drive the adjusting plate 3022 to rotate, so as to adjust the angle between the two adjusting plates 3022 on both sides and change the spraying range of the web nozzle assembly 302.

[0025] In this embodiment, the connecting member includes a transfer rod 316 fixedly installed on the middle connecting seat 313. Connecting holes 317 are provided at both ends of the transfer rod 316. Connecting strips 319 are fixedly installed on the remaining connecting seats 313. Telescopic rods 318 are rotatably installed on the connecting strips 319. The telescopic rods 318 are detachably connected to the connecting holes 317, and the connecting strips 319 are detachably connected to the adjacent telescopic rods 318. A rectangular rod 320 is fixedly installed on the connecting seat 313. A sleeve rod 321 is slidably installed on the rectangular rod 320. A spring 322 is fixedly installed inside the sleeve rod 321. The sleeve rod 321 is snap-connected to the connecting strip 319. Through the action of the telescopic rods 318 and the connecting strips 319, multiple connecting seats 313 can be driven to move synchronously. Therefore, multiple connecting seats 313 can be moved synchronously, the angles of multiple web spray head assemblies 302 can be adjusted synchronously, and the angles can be kept equal. Moreover, through the action of the spring 322, the stability of the connection between the sleeve rod 321 and the connecting strip 319 can be ensured.

[0026] Among them, the spacing adjustment assembly includes a third push rod motor 304 fixedly installed inside the chassis 102. The output shaft of the third push rod motor 304 is fixedly connected to the support frame 303. A first laser rangefinder 323 is fixedly installed on one of the first mixing tanks 310. The distance between the web spray head assembly 302 and the web can be detected by the first laser rangefinder 323, and this distance can be adjusted by the third push rod motor 304, so as to adjust the effective spraying range of the web spray head assembly 302.

[0027] As Figures 8 to 12 and Figure 14 shown, this embodiment further includes a chamfer spraying component 4. The chamfer spraying component 4 includes a chamfer spray head 401. The chamfer spray head 401 sprays on the chamfer to prevent the film on the chamfer from having inconsistent thickness. The chamfer spraying assembly further includes a range adjustment mechanism for adjusting the spraying range of the chamfer spray head 401, which can adapt to chamfers with different widths and lengths. The chamfer spraying component 4 further includes a positioning module for making the edge line of the spraying range of the chamfer spray head 401 coincide with the edge line of the chamfer 201 of the H-shaped steel 2. Through the positioning module, the chamfer spray head 401 can be quickly positioned, preventing the position of the chamfer spray head 401 from deviating and avoiding the chamfer spray head 401 from being unable to effectively cover the chamfer 201.

[0028] Further, the chamfering nozzle 401 includes a support shell 4011 and a rotating plate 4012 rotatably mounted on both sides of the support shell 4011. The rotation of the rotating plate 4012 can change the included angle between the two rotating plates 4012, thereby adjusting the spraying range of the chamfering nozzle 401. The positioning module includes a misaligned rod 402 fixedly mounted on one of the rotating plates 4012. A fourth push rod motor 403 is mounted on the misaligned rod 402 at a certain height. The fourth push rod motor 403 is parallel to the rotating plate 4012. A positioning block 404 is fixedly mounted on the output shaft of the fourth push rod motor 403. The positioning block 404 is perpendicular to the output shaft of the fourth push rod motor 403. Thus, the positioning block 404 can rotate as the rotating plate 4012 rotates and always remains parallel to the side of the rotating plate 4012, so that the center point of the positioning block 404 is always located on the extension line of the rotating plate 4012. The positioning module further includes a displacement mechanism for driving the chamfering nozzle 401 to move to coincide with the chamfer of the H-shaped steel 2. When the positioning block 404 coincides with the connecting line of the chamfer and the wing plate, the side line of the spraying range of the chamfering nozzle 401 can be made to coincide with the connecting line of the chamfer 201 and the wing plate under the action of the positioning block 404. After positioning, the fourth push rod motor 403 can be used to drive the positioning block 404 to disengage from the H-shaped steel 2 to prevent friction between the positioning block 404 and the H-shaped steel 2 during relative movement.

[0029] Among them, the displacement mechanism includes a mounting plate 411 slidably mounted on the web spraying component 3. A transmission block 409 is slidably mounted on the mounting plate 411. The transmission block 409 is connected to the chamfering nozzle 401 through a connecting shaft 407. By moving the transmission block 409, the chamfering nozzle 401 can be driven to move through the connecting shaft 407.

[0030] In this embodiment, a first driving cylinder 412 is slidably mounted on the mounting plate 411. A first sealing head 426 is slidably mounted in the first driving cylinder 412. A first push rod 413 is fixedly mounted on the first sealing head 426. The first push rod 413 is fixedly connected to the transmission block 409. A second driving cylinder 414 is slidably mounted on the mounting plate 411. A second sealing head 415 is slidably mounted in the second driving cylinder 414. A second push rod 416 is fixedly mounted on the second sealing head 415. The second push rod 416 is fixedly connected to the transmission block 409. By moving the first push rod 413 and the second push rod 416, the transmission block 409 can be driven to move. And when the first push rod 413 drives the transmission block 409 to move, the second driving cylinder 414 can be driven to slide on the mounting plate 411. When the second push rod 416 drives the transmission block 409 to move, the first driving cylinder 412 can also be driven to move.

[0031] Among them, an oil barrel 417 and a fifth push rod motor 419 are fixedly installed on the mounting plate 411. A plug 418 is slidably installed in the oil barrel 417, and the plug 418 is fixedly connected to the output shaft of the fifth push rod motor 419. Three-way joints 420 are installed at both the upper and lower ends of the oil barrel 417. Two oil pipes 421 are fixedly installed on the three-way joints 420. The other ends of the two oil pipes 421 are respectively communicated with the first driving cylinder 412 and the second driving cylinder 414. The oil pipes 421, the first driving cylinder 412, and the second driving cylinder 414 are all filled with a hydraulic medium, and the hydraulic medium is a liquid that cannot be compressed under the working environment. A pressure sensing component is provided in the fifth push rod motor 419, which can detect the pressure borne by the output shaft of the fifth push rod motor 419. When the fifth push rod motor 419 moves, it can drive the plug 418 to apply pressure to the hydraulic medium inside the oil barrel 417, and then the hydraulic medium can be transmitted through the oil pipe 421 to the inside of the first driving cylinder 412 and the second driving cylinder 414, and then the first push rod 413 and the second push rod 416 can be driven to move synchronously, so that the positioning block 404 can move along two directions at the same time. When the positioning block 404 is blocked by the chamfer or the wing plate and cannot move synchronously, the hydraulic pressure inside the oil barrel 417 will increase. This pressure can be judged by the pressure sensing component. When the pressure reaches the threshold value, the fifth push rod motor 419 will be closed, and at this time, the positioning of the positioning block 404 and the chamfer spraying head 401 will be completed.

[0032] It should be noted that a base 410 is slidably installed on the web spraying component 3. The base 410 is slidably connected to the slideway 307, and the mounting plate 411 is fixedly connected to the base 410. A sixth push rod motor 406 is fixedly installed on the connecting shaft 407. The sixth push rod motor 406 is perpendicular to the chamfer 201. By driving the sixth push rod motor 406, the tool spraying component can be moved, the linear distance between the chamfer spraying head 401 and the chamfer can be adjusted, and then the spraying range of the chamfer spraying head 401 can be adjusted. A second mixing box 405 is fixedly installed on the output shaft of the sixth push rod motor 406, and the chamfer spraying head 401 is fixedly connected to the second mixing box 405. The paint and the high-pressure gas will enter the second mixing box 405 and be sprayed out through the chamfer spraying head 401.

[0033] Furthermore, the range adjustment mechanism includes a protruding rod 422 fixedly installed on the rotating plate 4012. A transmission bar 423 is rotatably installed on the protruding rod 422. The two transmission bars 423 are rotatably connected through a sliding seat 424. A seventh push rod motor 425 is fixedly installed on the second mixing tank 405. The output shaft of the seventh push rod motor 425 is fixedly connected to the sliding seat 424. By driving the sliding seat 424 to slide through the seventh push rod motor 425, the rotating plates 4012 on both sides can be driven to rotate through the transmission bar 423, and thus the angle between the two rotating plates 4012 can be adjusted. A second laser rangefinder 408 is fixedly installed on the second mixing tank 405. The distance between the chamfering nozzle 401 and the chamfer is detected by the second laser rangefinder 408, and this distance can be adjusted by the sixth push rod motor 406, so as to accurately adjust the spraying range of the chamfering nozzle 401.

[0034] Working principle: Under the action of the first push rod motor 305, the driving plate 306 can be driven to move up and down, thereby driving multiple connecting rods 308 to rotate synchronously, and making the slider 324 slide. The connecting block 301 can be driven to move synchronously, and the distance between any two connecting blocks 301 can be ensured to be equal. Therefore, the distance between the web nozzle assemblies 302 connected to the connecting block 301 can be adjusted quickly.

[0035] The second push rod motor 315 can drive the connecting seat 313 to move up and down, and drive the swing rods 312 on both sides to rotate through the connecting seat 313. The rotating swing rods 312 will drive the adjusting plate 3022 to rotate, so as to adjust the angle between the two adjusting plates 3022 on both sides and change the spraying range of the web nozzle assembly 302.

[0036] When the positioning block 404 coincides with the edge line of the chamfer and the wing plate, the edge line of the spraying range of the chamfering nozzle 401 can be made to coincide with the connecting line of the chamfer 201 and the wing plate under the action of the positioning block 404. By driving the sliding seat 424 to slide through the seventh push rod motor 425, the rotating plates 4012 on both sides can be driven to rotate through the transmission bar 423, and thus the angle between the two rotating plates 4012 can be adjusted. A second laser rangefinder 408 is fixedly installed on the second mixing tank 405. The distance between the chamfering nozzle 401 and the chamfer is detected by the second laser rangefinder 408, and this distance can be adjusted by the sixth push rod motor 406, so as to accurately adjust the spraying range of the chamfering nozzle 401.

[0037] Example 2, such as Figure 13As shown in the figure, based on Embodiment 1, a connection component is provided between the connecting shaft 407 and the connecting rod 309.
