[0002] In the field of construction engineering, guardrails are key safety facilities for high-altitude operations and edge protection. Their surface coating process is of paramount importance. This process not only gives the guardrails an aesthetically pleasing decorative visual effect, but also undertakes the crucial function of corrosion protection. Scientific coating treatment can effectively improve the guardrails' ability to resist atmospheric, salt spray, and ultraviolet radiation, significantly extending their service life. Therefore, rigorous material selection, reasonable pretreatment, standardized spraying processes, and strict acceptance standards are decisive factors in ensuring that the project's visual quality and long-term protective performance meet the standards.

[0019] This invention provides a clamping spraying robot capable of painting high-altitude steel pipe structures.

[0020] Example 1: Please see Figure 1 The system includes a support frame 1, which is a rectangular structure welded from 50×50×3mm square tubing. The top is provided with an M10 threaded connection hole, and the bottom is equipped with height-adjustable feet with an adjustment range of ±50mm. An electrical control box is installed on the outer surface of the support frame 1. The electrical control box is electrically connected to the municipal power supply through wires, thereby ensuring that the electrical equipment in this application is powered normally.

[0021] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9An automatic mechanism 2 is installed inside the support frame 1. The automatic mechanism 2 includes a bearing box 201. The outer surface of the bearing box 201 is slidably connected to the support frame 1. Two active bidirectional worm gears 202 are rotatably connected to the inner wall of the bearing box 201. A driven worm wheel 203 is meshed between the two active bidirectional worm gears 202. A bearing frame 204 is rotatably connected to the top surface of the driven worm wheel 203. The outer surface of the bearing frame 204 is slidably connected to the bearing box 201. A connecting shaft 205 is rotatably connected to the inner wall of the bearing frame 204. By driving the two active bidirectional worm gears 202 to rotate simultaneously in the same direction, a meshing force in the same direction can be applied to both sides of the driven worm wheel 203, effectively making it move horizontally. When the two active bidirectional worm gears 202 are driven to rotate relative to each other simultaneously, a relative meshing force can be applied to both sides of the driven worm wheel 203, effectively making it rotate.

[0022] A driven meshing wheel 206 is fixedly connected to the outer surface of the connecting shaft 205. A first driven bevel gear 207 is fixedly connected to the outer surface of the driven meshing wheel 206. The outer surface of the first driven bevel gear 207 is fixedly connected to the connecting shaft 205. A second driven bevel gear 208 is meshed with the outer surface of the first driven bevel gear 207. A driven connecting shaft 209 is fixedly connected to the top surface of the second driven bevel gear 208. One end of the driven connecting shaft 209 away from the second driven bevel gear 208 is fixedly connected to the driven worm gear 203. By driving the driven connecting shaft 209 to rotate, the first driven bevel gear 207 on the surface of the second driven bevel gear 208 can be effectively driven to rotate synchronously. By driving the first driven bevel gear 207 to rotate, the driven meshing wheel 206 and the driven telescopic rod 215 can be driven to rotate simultaneously.

[0023] The outer surface of the driven meshing wheel 206 is meshed with a driven gear 210. The inner wall of the driven gear 210 is slidably connected to the support frame 204. The outer surface of the driven gear 210 is slidably connected to a limiting slider 211. The bottom surface of the limiting slider 211 is slidably connected to the support box 201. By driving the driven meshing wheel 206 to rotate, the driven gear 210 can be effectively driven to slide vertically on the support frame 204 and the limiting slider 211. The support frame 204 and the limiting slider 211 effectively limit the driven gear 210, so that the driven gear 210 can only slide vertically within the support frame 204 and the limiting slider 211.

[0024] A sliding plate 212 is slidably connected to the inner wall of the driven gear frame 210, and a meshing tooth 213 is fixedly connected to the outer surface of the sliding plate 212. A return spring 214 is sleeved inside the driven gear frame 210. One end of the return spring 214 is fixedly connected to the driven gear frame 210, and the other end of the return spring 214 away from the driven gear frame 210 is fixedly connected to the sliding plate 212. Through the synergistic action of the sliding plate 212 and the return spring 214, after the driven meshing wheel 206 drives the driven gear frame 210 to move up to a certain height, the driven meshing wheel 206 will mesh with the meshing tooth 213, so that the driven gear frame 210 cannot move up again, while the driven meshing wheel 206 can continue to rotate.

[0025] A driven telescopic rod 215 is rotatably connected to the inner wall of the carrying box 201. The telescopic end of the driven telescopic rod 215 is fixedly connected to the connecting shaft 205. A first driven sprocket 216 is fixedly connected to the fixed end of the driven telescopic rod 215. A first transmission chain 217 is drivenly connected to the outer surface of the first driven sprocket 216. A second driven sprocket 218 is drivenly connected to the outer surface of the first transmission chain 217. A driven roller 219 is rotatably connected to the inner wall of the carrying box 201. One end of the driven roller 219 is fixedly connected to the second driven sprocket 218. By driving the connecting shaft 205 to rotate, and in combination with the synergistic effect of the first driven sprocket 216, the first transmission chain 217, and the second driven sprocket 218, the two driven rollers 219 can be driven to rotate synchronously. A retaining ring is installed on the surface of the driven roller 219. The retaining ring makes the reciprocating collar 220 more stable when sliding horizontally back and forth.

[0026] A reciprocating collar 220 is fitted on the outer surface of the driven roller 219. The top surface of the reciprocating collar 220 is slidably connected to the bearing box 201. A reciprocating slide rod 221 is rotatably connected to the inner wall of the reciprocating collar 220. A reciprocating groove 222 adapted to the reciprocating slide rod 221 is opened on the outer surface of the driven roller 219. A hot air blower 223 is fixedly connected to the bottom surface of the reciprocating collar 220. An arc-shaped air delivery plate 224 is fixedly connected to the bottom surface of the hot air blower 223. Through the coordinated action of the reciprocating collar 220, the reciprocating slide rod 221 and the reciprocating groove 222, when the driven roller 219 is driven to rotate, the hot air blower 223 on the bottom surface of the reciprocating collar 220 can be driven to move horizontally and reciprocally within the bearing box 201. The inner wall of the arc-shaped air delivery plate 224 is provided with multiple air holes. The air holes can disperse the hot air to the surface of the steel pipe, greatly improving the paint drying efficiency.

[0027] Two drive motors 225 are fixedly connected to the inner wall of the carrier box 201. The output end of each drive motor 225 is fixedly connected to one end of each active bidirectional worm gear 202. An active screw 226 is rotatably connected to the inner wall of the support frame 1. A threaded slider 227 is threadedly connected to the outer surface of the active screw 226. The bottom surface of the threaded slider 227 is slidably connected to the support frame 1. The outer surface of the threaded slider 227 is fixedly connected to the carrier box 201. A rotary motor is fixedly installed inside the support frame 1. The output end of the rotary motor is fixedly connected to the active screw 226. By starting the rotary motor to drive the active screw 226 to rotate, the position of the carrier box 201 can be effectively adjusted, so that the steel pipe below the carrier box 201 can automatically move to the paint storage box 301 containing different colored paints. A central synchronous controller is installed inside the carrier box 201. The central synchronous controller controls the opening and closing of the two drive motors 225. The central synchronous controller is existing technology and is not shown in the figure. This application will not describe it in detail.

[0028] Example 2: Please refer to it again. Figure 1 , Figure 2 , Figure 10 , Figure 11 and Figure 12 The support frame 1 is equipped with a painting mechanism 3. The painting mechanism 3 includes a paint storage box 301. The bottom surface of the paint storage box 301 is fixedly connected to the support frame 1. The inner wall of the paint storage box 301 is slidably connected to a painting box 302. The inner bottom wall of the painting box 302 is provided with a drainage hole. The paint in the paint storage box 301 can be effectively immersed into the painting box 302 through the drainage hole.

[0029] A synchronous shaft 303 is rotatably connected to the inner wall of the paint storage tank 301. One end of the synchronous shaft 303 is fixedly connected to a driven meshing wheel 304. A rectangular gear frame 305 is meshed with the outer surface of the driven meshing wheel 304. The outer surface of the rectangular gear frame 305 is fixedly connected to the paint box 302. The driven meshing wheel 304 and the rectangular gear frame 305 are made of high-strength, high-temperature resistant and corrosion-resistant materials, so that they do not affect normal use when in the paint. A sealing ring is installed between the synchronous shaft 303 and the paint storage tank 301. The sealing ring can prevent the paint in the paint storage tank 301 from overflowing.

[0030] A third driven sprocket 306 is fixedly connected to the end of the synchronous rotating shaft 303 away from the driven meshing wheel 304. A second transmission chain 307 is driven to the outer surface of the third driven sprocket 306. A fourth driven sprocket 308 is driven to the outer surface of the second transmission chain 307. A third driven meshing wheel 309 is fixedly connected to the outer surface of the fourth driven sprocket 308. The outer surface of the third driven meshing wheel 309 is rotatably connected to the support frame 1 via a connecting rod. A driven rack 310 is fixedly connected to the outer surface of the bearing box 201. The bottom surface of the driven rack 310 meshes with the third driven meshing wheel 309. By driving the driven rack 310 to move within the support frame 1, the third driven meshing wheel 309 can be effectively driven to rotate synchronously. The rotation of the third driven meshing wheel 309 can effectively drive the second transmission chain 307 on the surface of the fourth driven sprocket 308 to perform transmission.

[0031] A driven meshing wheel four 311 is fixedly connected to the outer surface of the third driven sprocket 306. A driven rack two 312 is meshed with the outer surface of the driven meshing wheel four 311. The outer surface of the driven rack two 312 is slidably connected to the paint storage box 301. A sealing door plate 313 is fixedly connected to one end of the driven rack two 312. The bottom surface of the sealing door plate 313 is slidably connected to the paint storage box 301. A magnetic sealing strip 314 is fixedly connected to the outer surface of the sealing door plate 313. A stainless steel spindle 315 is rotatably connected to the inner wall of the paint box 302. A high-density nylon roller brush 316 is fixedly connected to the outer surface of the stainless steel spindle 315. A rotary motor is installed inside the paint box 302. The output end of the rotary motor is fixedly connected to the stainless steel spindle 315. By starting the rotary motor, the high-density nylon roller brush 316 on the stainless steel spindle 315 is driven to rotate. Through the rotation of the high-density nylon roller brush 316, the steel pipe can be brushed when the paint box 302 is raised, and the paint can be agitated when the paint box 302 is lowered and immersed in the paint storage box 301. The magnetic sealing strip 314 can make the two sealing door panels 313 seal the paint storage box 301 more tightly, and prevent the sealing door panels 313 from shifting due to device vibration.

[0032] The drive motor 225 in this application is a common electrical device in the prior art. This application will not elaborate on its model and internal structure. It can also be replaced by other power sources.

[0033] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0034] Working principle: By driving two active bidirectional worm gears 202 to rotate in the same direction, a meshing force in the same direction is effectively applied to both sides of the two driven worm gears 203. This causes the support frames 204 on the top surfaces of the two driven worm gears 203 to slide closer to each other within the inner wall of the support box 201. Since the driven gear frame 210 is perpendicularly slidably connected to the support frame 204, the two support frames 204 will synchronously drive the two driven gear frames 210 to move closer to each other during the sliding process. The movement of the two driven gear frames 210 drives the lifting rods on their surfaces to lift and constrain the steel pipe. After the lifting is completed, the active screw 226 is driven to rotate. The rotation of the active screw 226 drives the support box 201 on the surface of the threaded slider 227 to move closer to each other within the inner wall of the support frame 1. As the carrier box 201 slides, it moves the brush-carrying steel pipe below it to a position directly above a paint storage box 301. During the sliding process within the support frame 1, the carrier box 201 simultaneously drives the driven rack 310 to engage with a driven meshing wheel 309. The rotation of the driven meshing wheel 309 drives the second transmission chain 307 on the surface of the fourth driven sprocket 308. The second transmission chain 307 drives the third driven sprocket 306 to rotate. The rotation of the third driven sprocket 306 drives the driven meshing wheel 311 and the driven meshing wheel 304 on one end of the synchronous rotating shaft 303 to rotate simultaneously. The rotation of the driven meshing wheel 311, combined with the synergistic effect of the two driven racks 312, effectively moves the two sealing door panels 313 away from each other, thus storing the paint. The opening at the top of the box 301 opens. Simultaneously, the driven meshing wheel 304 rotates, and through meshing force, drives the paint box 302 on the surface of the rectangular gear frame 305 to slide upwards within the paint storage box 301. This causes the high-density nylon roller brush 316 inside the paint box 302 to emerge from the paint in the paint storage box 301. At this point, the two active bidirectional worm gears 202 are driven to rotate simultaneously relative to each other, effectively applying a relative meshing force to both sides of the two driven worm gears 203, causing them to rotate. The rotation of the driven worm gears 203 drives the second driven bevel gear 208 on one end of the driven connecting shaft 209 to rotate. The rotation of the second driven bevel gear 208 drives the driven meshing wheel 206 on the surface of the first driven bevel gear 207 to rotate. The rotation of the driven meshing wheel 206 drives the driven meshing wheel 206 on the surface of the first driven bevel gear 207 to rotate. The moving gear 210 slides up and down the support frame 204 and the limiting slider 211. The downward movement of the limiting slider 211 effectively drives the steel pipe to move down synchronously and contact the high-density nylon roller brush 316 rotating below for painting. After painting, the two active bidirectional worm gears 202 are driven to rotate again, moving the steel pipe up into the support box 201. After the steel pipe enters the support box 201, the driven meshing wheel 206 will simultaneously mesh with the meshing tooth 213. Through the synergistic action of the sliding plate 212 and the return spring 214, the driven meshing wheel 206 can continuously mesh with the meshing tooth 213, effectively limiting the driven gear 210 and preventing it from moving up again. As the driven meshing wheel 206 continues to rotate, it will drive the connecting shaft 205 to rotate synchronously.The rotation of the connecting shaft 205 drives the first driven sprocket 216 on the fixed end of the driven telescopic rod 215 to rotate. The rotation of the first driven sprocket 216, combined with the synergistic action of the two first transmission chains 217 and the second driven sprocket 218, can drive the two driven rollers 219 to rotate simultaneously. During the rotation of the driven rollers 219, in conjunction with the cooperation of the reciprocating collar 220, the reciprocating slide bar 221, and the reciprocating slide groove 222, the hot air fan 223 is effectively driven to reciprocate horizontally inside the bearing box 201. The hot air fan 223, which is moving horizontally, delivers hot air into the arc-shaped air delivery plate 224. The system effectively dries the steel pipes after roller brushing. This is achieved by driving two active bidirectional worm gears 202 to rotate in different ways, and by combining this with the drive screw 226 to cause the bearing box 201 to slide horizontally within the inner wall of the support frame 1. This effectively achieves automated painting of the guardrail steel pipes. This design significantly improves painting efficiency and quality, greatly shortens the construction cycle, and effectively reduces the labor intensity and cost of traditional painting processes. It also greatly enhances the level of automation, further increasing the safety and practical value of the device.
