Description

Technical Field

[0001] The present invention relates to the technical field of construction coating equipment, in particular to a coating equipment for construction. Background Art

[0002] During the construction process, the walls need to be painted to meet different decoration styles. The general painting process is divided into the spraying of primer and the spraying of color paint. At present, the two types of painting are generally performed manually by painters, and the work efficiency is relatively low. When carrying out large-scale decoration painting, in order to improve work efficiency, it is necessary to cooperate with the corresponding painting equipment to operate.

[0003] At present, regarding the problem of wall painting, when spraying the walls around the interior of a building, if the primer is not scraped and leveled, some of the primer will form a sagging phenomenon on the wall.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the setting of the adjusting device of the present invention, by rotating the connecting helical teeth, the two trapezoidal blocks move in the same direction in the sliding groove. When one of the trapezoidal blocks approaches the first adjusting roller on the first connecting plate, the leveling roller contacts the painted wall surface to evenly apply the primer on the wall surface.

[0019] 2. Through the setting of the leveling device of the present invention, by moving the limiting grip, the guiding wheel is removed from the slot. Under the action of the limiting rod, the limiting grip is rotated to drive the equipment housing to rotate. The guiding wheel moves in the arc-shaped groove, making the opening direction of the nozzle face upward. The limiting grip is released under the action of the return spring, and the guiding wheel is inserted into the slot to limit the equipment housing, avoiding the situation where the painting equipment cannot automatically spray the wall surface on the top inside the building, resulting in low spraying efficiency.

[0020] 3. Through the setting of the anti-splash device of the present invention, when the trapezoidal block approaches the second connecting plate, the second adjusting roller rolls on the trapezoidal block, causing the second connecting plate to drive the second U-shaped plate to move out of the second limiting slot. The second U-shaped plate drives the hypotenuse plate to approach the wall, collecting the splashed primer, avoiding the situation where a large amount of primer overflows into the air and affects the physical health of the construction workers.

[0021] 4. Through the setting of the lifting device of the present invention, by starting the adjusting motor, the adjusting screw rod at the output end rotates inside the equipment housing, and the equipment housing moves up and down along the fixed column. The movement of the equipment housing drives the connecting frame to move. Under the action of the connecting block, the movement of the connecting frame drives the connecting frame to move inside the support pipe, avoiding the situation where the inconvenient movement of the equipment reduces the work efficiency of the construction workers.

[0032] The following will cooperate with the drawings and embodiments to elaborate on the implementation mode of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0033] Embodiment 1

[0034] Since the equipment needs to adjust the horizontal height of the nozzle during the painting process to evenly spray paint on the entire wall surface, but the nozzle orientation always remains perpendicular to the surrounding wall surfaces inside the building. If the ceiling wall inside the building needs to be painted, construction workers need to hold a spray gun and step on a ladder to spray it, which not only has a poor spraying effect, but also the restricted movement method greatly reduces the spraying efficiency. To solve this problem, refer to Figures 1 - 8, this embodiment proposes a painting device for building construction. By setting the adjusting device 2, the problem that the painting device cannot automatically spray the wall on the top inside the building, resulting in low spraying efficiency, is solved. The device includes a support base 1, on which a support frame 11 is fixedly installed. A connecting frame 12 is slidably installed on the support frame 11. A device housing 13 is rotatably installed on the connecting frame 12. A number of groups of nozzles 14 are installed on the device housing 13. A storage tank 7 is fixedly installed on the support base 1. The paint used for spraying is stored in the storage tank 7. A delivery pipe 701 communicating with the device housing 13 is fixedly installed on the storage tank 7. The paint in the storage tank 7 is pumped by a water pump in the storage tank 7 to the delivery pipe 701 and sprayed out through the nozzles 14;

[0035] An adjusting device 2 for adjusting the angle of the nozzles 14 is installed on the connecting frame 12. Each group of the adjusting device 2 includes two arc-shaped grooves 201 opened on the connecting frame 12. Two slots 202 communicating with each arc-shaped groove 201 are opened on each group of arc-shaped grooves 201. Two limiting rods 203 are fixedly installed on the device housing 13. A return spring 204 is sleeved on each limiting rod 203. A limiting grip 205 is slidably installed on the limiting rod 203. The return spring 204 enables the limiting grip 205 to quickly reset. Two guiding wheels 206 used in cooperation with the arc-shaped grooves 201 are fixedly installed on the limiting grip 205. When the guiding wheels 206 move to the position of the slots 202, they can limit the device housing 13. When spraying the top wall inside the building, move the limiting grip 205 to move the guiding wheels 206 out of the slots 202. Under the action of the limiting rod 203, rotate the limiting grip 205 to drive the device housing 13 to rotate. The guiding wheels 206 move in the arc-shaped grooves 201, so that the opening direction of the nozzles 14 faces upward. Release the limiting grip 205 under the action of the return spring 204 to make the guiding wheels 206 insert into the slots 202 to limit the device housing 13, avoiding the situation that the painting device cannot automatically spray the wall on the top inside the building, resulting in low spraying efficiency.

[0036] Embodiment Two

[0037] When performing primer spraying treatment, when spraying the surrounding walls inside the building, if the primer is not leveled, some primer will form a sagging phenomenon on the wall. When spraying the top wall inside the building, if the primer is not leveled, some primer will continuously drip down, affecting the overall painting effect. To solve this problem, refer to Figures 1 - 8, two sets of leveling devices 3 for preventing some primer from forming sagging on the wall surface are installed on the equipment housing 13. Each set of leveling devices 3 includes a sliding groove 301 opened on the equipment housing 13. Two sets of support rods 302 are fixedly installed on each sliding groove 301. A trapezoidal block 303 slidably connected to the support rods 302 is slidably installed on each sliding groove 301. Under the action of the support rods 302, the trapezoidal block 303 moves more stably. Two sets of first limiting grooves 304 are opened on the equipment housing 13. A first U-shaped plate 305 is slidably installed in the first limiting grooves 304. A leveling roller 306 is rotatably installed on the first U-shaped plate 305, which can evenly apply the primer on the wall surface. Each set of leveling devices 3 further includes a first connecting plate 307 slidably installed in the sliding groove 301 and fixedly connected to the first U-shaped plate 305. A first adjusting roller 308 cooperating with the trapezoidal block 303 is rotatably installed on the first connecting plate 307. Four sets of first fixing rods 309 slidably connected to the first U-shaped plate 305 are fixedly installed on each set of first limiting grooves 304. A first spring 310 is sleeved on each set of first fixing rods 309, enabling the first U-shaped plate 305 to quickly reset. Each set of leveling devices 3 further includes a rotating column 311 rotatably installed on the equipment housing 13. A driving screw 312 threadedly connected to the trapezoidal block 303 is installed on the rotating column 311. One end of the rotating column 311 is sleeved with a damping rotating shaft 313. A connecting helical gear 314 is fixedly installed on the damping rotating shaft 313. Under the action of the driving device 6, the connecting helical gear 314 rotates. The rotation of the connecting helical gear 314 drives the rotating column 311 connected to the damping rotating shaft 313 to rotate. The rotation of the rotating column 311 drives the two driving screws 312 to rotate in the two trapezoidal blocks 303 respectively, causing the two trapezoidal blocks 303 to move in the same direction in the sliding groove 301. Under the action of the damping rotating shaft 313, when the trapezoidal block 303 moves to one side of the sliding groove 301 and the rotation direction of the connecting helical gear 314 does not change, the damping rotating shaft 313 will rotate together with the connecting helical gear 314, and the rotating column 311 will stop rotating. When one of the trapezoidal blocks 303 approaches the first adjusting roller 308 on the first connecting plate 307, the first adjusting roller 308 rolls on the trapezoidal block 303, causing the first U-shaped plate 305 to move out of the first limiting groove 304. The leveling roller 306 contacts the painted wall surface and evenly applies the primer on the wall surface. The other trapezoidal block 303 moves away from the first adjusting roller 308 on the first connecting plate 307, causing the first U-shaped plate 305 to move into the first limiting groove 304. As the moving direction of the equipment changes, the two leveling rollers 306 alternately contact the wall surface, avoiding the situation where the primer forms a sagging phenomenon on the wall surface and some primer continuously drips down.

[0038] Embodiment III

[0039] Since the two leveling rollers work alternately following the moving direction of the equipment, during the painting process of the equipment, some primer will spread out with the rebounding air flow. The leveling roller extending from one side will block more primer and reapply it on the wall. The leveling roller on the other side is located behind and cannot play a shielding effect. The presence of more primer in the air will affect the physical health of the construction workers. To solve this problem, referring to Figures 1 - 8 Two splash-proof devices 4 for preventing some primer from splashing are installed on the equipment housing 13. Each splash-proof device 4 includes two second limiting grooves 401 opened on the equipment housing 13. A second U-shaped plate 402 is slidably installed on the second limiting groove 401. An inclined side plate 403 is fixedly installed on the second U-shaped plate 402 to shield the splashing primer and prevent more primer from spreading in the air. A collection groove 404 is opened on the inclined side plate 403 for collecting the splashing primer. A second connecting plate 405 fixedly connected to the second U-shaped plate 402 is slidably installed on the sliding groove 301. A second adjusting roller 406 used in cooperation with the trapezoidal block 303 is rotatably installed on the second connecting plate 405. Four second fixing rods 407 slidably connected to the second U-shaped plate 402 are fixedly installed on each second limiting groove 401, making the movement of the second U-shaped plate 402 more stable. A second spring 408 is sleeved on each second fixing rod 407, enabling the second U-shaped plate 402 to quickly reset. When the trapezoidal block 303 approaches the second connecting plate 405, the second adjusting roller 406 rolls on the trapezoidal block 303, causing the second connecting plate 405 to drive the second U-shaped plate 402 to move out of the second limiting groove 401. The second U-shaped plate 402 drives the inclined side plate 403 to approach the wall to collect the splashing primer, avoiding the situation where more primer spreads in the air and affects the physical health of the construction workers.

[0040] Embodiment Four

[0041] Since the equipment cannot automatically move to the next painting area during the painting process, the construction workers need to continuously move the equipment during the process, reducing the work efficiency of the construction workers. To solve this problem, referring to Figures 1 - 8, a lifting device 5 for adjusting the position of the equipment housing 13 is installed on the support frame 11. The lifting device 5 includes an adjusting motor 501 fixedly installed on the support frame 11. The output end of the adjusting motor 501 is fixedly installed with an adjusting screw rod 502 threadedly connected to the equipment housing 13. A fixed column 503 slidably connected to the equipment housing 13 is fixedly installed on the support frame 11, making the movement of the equipment housing 13 more stable. A support pipe 504 is rotatably installed on the support base 1. The lifting device 5 further includes a connecting rod 505 fixedly installed on the support pipe 504. A sliding rod 506 slidably connected to the connecting rod 505 is slidably installed on the support pipe 504. A slot 507 for cooperating with the connecting rod 505 is formed on the sliding rod 506. The connecting rod 505 can move within the slot 507. A driving bevel gear 508 meshing with the connecting bevel gear 314 is fixedly installed on the sliding rod 506. A connecting block 509 rotatably connected to the sliding rod 506 is fixedly installed on the connecting frame 12, making the meshing of the driving bevel gear 508 and the connecting bevel gear 314 unaffected by the movement of the equipment housing 13. A driving device 6 for driving the leveling device 3 and the splash-proof device 4 is installed on the support base 1. With the start of the driving device 6, the two splash-proof devices 4 and the leveling device 3 alternately move on the equipment housing 13, enabling the splash-proof device 4 and the leveling device 3 to perform their respective operations better. The driving device 6 includes a driving motor 601 fixedly installed on the support base 1. The output end of the driving motor 601 is fixedly installed with a driving gear 602. Two driving rods 603 are rotatably installed on the support base 1. A connecting gear 604 meshing with the driving gear 602 is fixedly installed on one of the driving rods 603. A worm 605 is fixedly installed on the driving rod 603. A worm gear 606 meshing with the worm 605 is fixedly installed on the support pipe 504. Two rollers 607 are fixedly installed on each driving rod 603. Starting the driving motor 601 causes the driving gear 602 at the output end to rotate, driving the driving rod 603 connected to the connecting gear 604 to rotate. The rotation of the driving rod 603 drives the worm gear 606 meshing with the worm 605 to rotate. The rotation of the worm gear 606 drives the support pipe 504 to rotate. Under the action of the connecting rod 505, the rotation of the support pipe 504 drives the driving bevel gear 508 connected to the sliding rod 506 to rotate. When it is necessary to adjust the height of the nozzle 14, start the adjusting motor 501 so that the adjusting screw rod 502 at the output end rotates within the equipment housing 13. The equipment housing 13 moves up and down along the fixed column 503. The movement of the equipment housing 13 drives the connecting frame 12 to move. Under the action of the connecting block 509, the movement of the connecting frame 12 drives the connecting frame 12 to move within the support pipe 504, avoiding the situation where the equipment is inconvenient to move and reducing the work efficiency of the construction personnel.

[0042] Working principle: Moving the limit grip 205 causes the guide wheel 206 to move out of the slot 202. Under the action of the limit rod 203, rotating the limit grip 205 drives the device housing 13 to rotate. The guide wheel 206 moves within the arc-shaped groove 201, causing the opening direction of the nozzle 14 to face upward. Releasing the limit grip 205 under the action of the return spring 204 causes the guide wheel 206 to insert into the slot 202, limiting the device housing 13 and avoiding the situation where the painting equipment cannot automatically spray the wall on the top inside the building, resulting in low spraying efficiency.

[0043] Starting the drive motor 601 causes the drive gear 602 at the output end to rotate, driving the drive rod 603 and the roller 607 connected to the connecting gear 604 to rotate. The rotation of the drive rod 603 drives the worm gear 606 meshing with the worm 605 to rotate. The rotation of the worm gear 606 drives the support tube 504 to rotate. Under the action of the connecting rod 505, the rotation of the support tube 504 drives the drive helical gear 508 connected to the sliding rod 506 to rotate, thereby causing the connecting helical gear 314 to rotate and driving the rotating column 311 connected to the damping rotating shaft 313 to rotate. The rotation of the rotating column 311 drives the two drive screws 312 to rotate respectively within the two trapezoidal blocks 303, causing the two trapezoidal blocks 303 to move in the same direction within the sliding groove 301. Under the action of the damping rotating shaft 313, when the trapezoidal block 303 moves to one side of the sliding groove 301 and the rotation direction of the connecting helical gear 314 does not change, the damping rotating shaft 313 will rotate together with the connecting helical gear 314, and the rotating column 311 will stop rotating. When one of the trapezoidal blocks 303 approaches the first adjusting roller 308 on the first connecting plate 307, the first adjusting roller 308 rolls on the trapezoidal block 303, causing the first U-shaped plate 305 to move out of the first limiting groove 304. The leveling roller 306 contacts the wall after painting and spreads the primer on the wall evenly. The other trapezoidal block 303 moves away from the first adjusting roller 308 on the first connecting plate 307, causing the first U-shaped plate 305 to move into the first limiting groove 304. As the moving direction of the device changes, the two leveling rollers 306 alternately contact the wall. When the trapezoidal block 303 approaches the second connecting plate 405, the second adjusting roller 406 rolls on the trapezoidal block 303, causing the second connecting plate 405 to drive the second U-shaped plate 402 to move out of the second limiting groove 401. The second U-shaped plate 402 drives the inclined side plate 403 to approach the wall to collect the splashed primer, avoiding the situation where a large amount of primer overflows into the air and affects the health of construction workers.

[0044] When it is necessary to adjust the height of the nozzle 14, start the adjustment motor 501 to make the adjustment screw rod 502 at the output end rotate within the equipment housing 13. The equipment housing 13 moves up and down along the fixed column 503. The movement of the equipment housing 13 drives the connecting frame 12 to move. Under the action of the connecting block 509, the movement of the connecting frame 12 drives the connecting frame 12 to move within the support pipe 504, avoiding the situation that the inconvenient movement of the equipment reduces the work efficiency of the construction workers.
