TECHNICAL FIELD
[0001] The present application mainly relates to the technical field of electric arc spraying, in particular to a hot-dip galvanizing furnace nose wall plate spraying equipment. BACKGROUND
[0002] Hot-dip galvanizing is an important process for corrosion protection of steel materials. The furnace nose, as a key component in the galvanizing production line, is exposed to high-temperature, high-corrosion zinc liquid vapor and spatter environment for a long time. The performance of the inner wall protective coating directly affects the service life and operation stability of the equipment. Electric arc spraying technology has become one of the mainstream processes for protecting the surface of the furnace nose wall plate, due to its high coating bond strength, good high-temperature oxidation and corrosion resistance, and other advantages.
[0003] Existing automatic spraying equipment for such large curved wall plates usually uses a multi-axis robot arm to carry a spray gun and performs trajectory operations according to a preset program. However, there are still obvious deficiencies in practical applications. First, it is difficult to ensure absolute perpendicularity or theoretical posture when clamping the wall plate. A slight initial tilt can cause the spraying trajectory to deviate, affecting the uniformity of the coating. Second, for wall plate surfaces with complex curvature, traditional equipment cannot accurately maintain the optimal constant distance between the spray gun and the workpiece surface in real time, resulting in uneven coating thickness. More importantly, the local high heat generated by continuous spraying can easily accumulate thermal stress inside the coating, inducing micro-cracks and seriously affecting the long-term protective effect of the coating. These technical bottlenecks restrict the further improvement of spraying quality and process automation.
[0004] Therefore, there is a need for a spraying equipment that can realize automatic spraying and avoid micro-cracks caused by thermal stress in the coating. SUMMARY

[0028] The working principle of the present application is as follows: When the hot-dip galvanizing furnace nose wallboard is sprayed, the wallboard is first hoisted to the plate body clamp 12 by the hoisting equipment, and the plate body clamp 12 clamps and fixes the wallboard; After the plate body clamp 12 fixes the wallboard, the plate body posture correction module 51 triggers the three-axis positioning device 20 and the plate surface measuring device 40 to move along the horizontal direction of the wallboard from one end of the wallboard to the other end of the wallboard, in the moving process, the plate body posture correction module 51 obtains the moving information of the Y-axis moving component 23 and the distance information measured by the distance measuring component 45, analyzes and obtains the plate body deflection information value through the change amount of the sum of the moving information of the Y-axis moving component 23 and the distance information measured by the distance measuring component 45, and triggers the adjusting component 13 according to the plate body inclination information, until the plate body deflection information value is within the set range. After the board posture correction is completed, the board surface measurement module 52 triggers the three-axis positioning device 20 and the board surface measurement device 40 to move along the vertical direction of the wallboard from the top of the wallboard to the bottom of the wallboard. The board surface measurement module 52 measures the sum of the two-dimensional coordinate Y value according to the displacement detection wheel 44 measurement information and the two-dimensional coordinate X value according to the Y-axis moving component 23 movement information and the distance measurement component 45 distance measurement information, to generate wallboard surface curve information; The skip spraying division module 53 generates skip spraying information according to the wallboard surface curve information. The skip spraying information includes first spraying sections and second spraying sections arranged in sequence from top to bottom along the wallboard. The first spraying sections and the second spraying sections are staggered. The skip spraying method can effectively avoid micro-cracks caused by thermal stress. When generating the skip spraying information, only the Y value in the two-dimensional coordinate needs to be set, and the X value in the two-dimensional coordinate is adjusted by the distance measurement component 32. When arc spraying is performed on the same column of spraying sections of the wallboard, all the first spraying sections are sprayed in sequence, and then the second spraying sections are sprayed. The single spraying distance setting module 54 sets the length of the first spraying sections and the second spraying sections. Before arc spraying, the distance measurement component 32 moves to the detection position. The X-axis moving component 21 moves from the initial point to the termination point according to the spraying section length. The spraying path copying module 55 receives the distance information between the distance measurement component 32 and the wallboard surface and triggers the Y-axis moving component 23 after analysis to keep the distance information within the set range. During this process, the spraying path copying module 55 automatically records the movement amount information and movement time information of the Y-axis moving component 23 during the movement of the X-axis moving component 21. During arc spraying, the X-axis moving component 21 performs end reset and moves from the initial point to the termination point according to the spraying section length again. The arc spray head 31 sprays molten metal liquid. The spraying path copying module 55 adjusts the Y-axis moving component 23 according to the movement amount information and the movement time information to realize the spraying of the spraying section. This spraying method can ensure that the distance between the arc spray head 31 and the wallboard remains unchanged. When the board body clamp 12 is working, the first hydraulic cylinder 125 execution end drives multiple moving clamping plates 124 to limit and clamp the bottom end of the wallboard through the power plate 126. The second hydraulic cylinder 127 execution end drives the L-shaped clamping plate 128 to descend to clamp the top of the wallboard. The wallboard is limited and clamped under the joint action of the moving clamping plates 124, the L-shaped clamping plate 128, and the L-shaped bracket 123. When the adjusting component 13 is working, the transmission motor 138 execution end drives the second worm 137 to rotate. The second worm 137 drives the second worm gear ring 136 to rotate. The second worm gear ring 136 drives the second screw rod 135 to rotate. The second screw rod 135 drives the displacement block 133 to move along the guide rail 132. The displacement block 133 drives the driving column 134 to slide in the driving ring 131 when moving. The driving ring 131 drives the rotating plate 121 to rotate. When the distance measuring component 32 works, the micro electric cylinder 323 executes the first distance measuring sensor 324 to move out of the protective baffle 322, and the first distance measuring sensor 324 measures the distance information between the wallboard and the outer wall and transmits the distance information to the control center 50. When the three-axis positioning device 20 works, the working principles of the X-axis moving component 21, the Y-axis moving component 23 and the Z-axis moving component 25 are consistent. Taking the working of the X-axis moving component 21 as an example, the driving motor 213 executes the first lead screw 214 to rotate, and the first lead screw 214 drives the moving block 212 to move. When the first lead screw 214 rotates, the first lead screw 214 can also drive the first encoder 216 to rotate through the first gear 215. The first encoder 216 transmits the rotation angle information of the first lead screw 214 to the control center 50. The control center 50 can obtain the position information of the moving block 212 through the rotation angle and the set pitch information. The control center 50 receives the wallboard picture information shot by the industrial camera 452 and triggers the three-axis positioning device 20 after analysis to move the electric arc spraying device 30 or the plate surface measuring device 40 to the initial position. When the plate surface measuring device 40 works, the angle positioning component 41 is convenient for adjusting the angle of the positioning box 42. When detecting, the displacement detection wheel 44 abuts against the surface of the wallboard. The control center 50 receives the pressure information measured by the elastic pressure measuring support component 46 and the distance information between the measuring frame 43 measured by the second distance measuring sensor 451, and triggers the Y-axis moving component 23 according to the pressure information to ensure that the pressure information is within the set range. The sum of the distance information and the movement information of the Y-axis moving component 23 is the two-dimensional coordinate X value. When the angle positioning component 41 works, the power motor 414 executes the first worm 415 to rotate, and the first worm 415 drives the positioning tube 411 to rotate through the first worm gear ring 413. The first electric cylinder 412 executes the positioning box 42 to move. When the displacement detection wheel 44 works, the second encoder 444 detects the rotation of the roller 442 through the second gear 443 when the roller 442 rotates. The control center 50 receives the angle information measured by the second encoder 444 and obtains the displacement information according to the diameter of the roller 442. When the elastic pressure measuring support component 46 works, the measuring frame 43 slides in the positioning box 42 to give the pressure sensor 461 pressure through the spring 463. The greater the compression amount of the spring 463, the greater the value of the pressure sensor 461.
