Description

An intelligent building painting device Technical Field

[0001] This invention relates to the field of building painting technology, specifically an intelligent building painting device. Background Technology

[0002] Plastering acts as a protective layer for walls, effectively resisting erosion from natural elements such as wind, rain, snow, and sun. For example, if rainwater directly contacts the wall material, it will gradually seep in, causing the wall to become damp. Plastering prevents rainwater intrusion, preventing problems such as softening, mold, and damage caused by dampness.

[0003] To improve plastering efficiency, intelligent building painting devices have emerged that can replace manual plastering. Walls often have small protruding stones or other dirt. If these are not cleaned, stress concentration points can easily form around these impurities as the plaster layer dries and shrinks. For example, the mortar around dust particles may shrink at different rates than other areas, leading to cracks. Furthermore, the presence of impurities can prevent the mortar from filling evenly during application, resulting in localized voids. These voids and cracks not only affect the appearance of the plaster layer but also reduce its waterproofing and insulation functions. However, existing painting devices cannot remove small stones from the wall while plastering, significantly reducing the quality of the plastering.

[0004] Based on this, an intelligent building painting device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

A lifting box is slidably arranged between the guide rails of the two guide rails. A plastering plate is movably arranged on the side wall of the lifting box. A feeding plate is rotatably connected to the upper surface of the lifting box via a pin shaft. The feeding plate is driven by an electric push rod located inside the lifting box. A gear is rotatably arranged on the outer side wall of the lifting box via a rotating shaft. A rack is fixedly connected to the side wall of the guide rails, and the rack meshes with the gear. A second motor is fixedly connected to the inner side wall of the lifting box via a bracket. The output end of the second motor is connected to the gear shaft.

[0008] The cleaning component is located above the lifting box and is used to clean small stone particles from the wall.

[0009] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

The two rotating rods are together fixedly connected to the collection box via a rotating frame. The outer side wall of the collection box is provided with a scraper.

[0011] In one alternative embodiment: two symmetrical sliding rods are provided on the lower surface of the collection box. Each sliding rod is fixedly connected to an mounting cylinder. Both mounting cylinders are connected to a rotating rod via bearings. Friction wheels are fixedly connected to both ends of the rotating rod. Three annular grooves are formed around the rotating rod. Three reciprocating sliders are slidably connected through the rotating rod, each corresponding to one of the three annular grooves. Each reciprocating slider is equipped with an eccentric shaft, which is slidably connected to the inner wall of the annular groove. A rope block tube is rotatably connected to the reciprocating slider via a pin. A telescopic block is slidably connected through the rope block tube. A T-shaped slot is formed on the side wall of the collection box. Several T-shaped blocks are slidably connected to the inner wall of the T-shaped slot. Several T-shaped blocks are fixedly connected to a reciprocating plate, which is detachably connected to a scraper.

[0012] In one alternative: two symmetrical guide blocks are fixedly connected to the lower surface of the collection box, the sliding rod is slidably connected to the guide blocks, a first limiting plate and a second limiting plate are fixedly connected to the side wall of the sliding rod, and a spring is fixedly connected between the second limiting plate and the guide block.

The reciprocating slider drives the reciprocating plate to move back and forth through the telescopic block and the rope block cylinder. The reciprocating plate drives the scraper to move back and forth, improving the scraper's cleaning effect on small stones attached to the wall.

[0019] 3. This invention uses a spray nozzle to spray water to reduce dust as the lifting box rises, preventing dust from scattering in the air and affecting the construction environment, and also preventing dust from coming into contact with plaster and affecting the plaster quality.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, as shown in Figures 1-13, an intelligent building painting device includes a base 1, casters 2, guide rails 4, and cleaning components 7. Two symmetrical guide rails 4 are fixedly connected to the upper surface of the base 1. A lifting box 5 is slidably arranged between the guide rails of the two guide rails 4. A plastering plate 9 is movably arranged on the side wall of the lifting box 5. A feeding plate 8 is rotatably connected to the upper surface of the lifting box 5 via a pin shaft. The feeding plate 8 is driven by an electric push rod located inside the lifting box 5. A gear 13 is rotatably arranged on the outer side wall of the lifting box 5 via a rotating shaft. A rack 14 is fixedly connected to the side wall of the guide rails 4. The rack 14 meshes with the gear 13. A second motor 12 is fixedly connected to the inner side wall of the lifting box 5 via a bracket. The output end of the second motor 12 is connected to the rotating shaft of the gear 13.

[0036] The cleaning component 7 is located above the lifting box 5 and is used to clean small stone particles from the wall.

[0037] First, move the painting device to the area to be plastered using the casters 2, turn on the rangefinder 6, adjust the distance between the device and the wall, and then fix the device in place using the positioning rod 3 to prevent the device from moving during the plastering process.

[0038] In one embodiment, the cleaning component 7 includes a scraper 17 and a collection box 29. The side wall of the lifting box 5 is rotatably connected to two symmetrical rotating rods 15 via bearings. The inner side wall of the lifting box 5 is fixedly connected to a first motor 11 via a bracket. The output end of the first motor 11 is fixedly connected to one of the rotating rods 15. The two rotating rods 15 are fixedly connected to the collection box 29 via a rotating frame 16. The outer side wall of the collection box 29 is provided with a scraper 17.

[0039] As the lifting box 5 rises, it also lifts the collection box 29. During the rise of the collection box 29, the scraper 17 cleans up the small stones protruding from the wall, and the cleaned stones fall into the collection box 29.

[0040] When the plaster layer dries and shrinks, avoid creating stress concentration points around small stones, as this can cause the mortar to shrink at different rates than other parts, resulting in cracks.

[0041] In one embodiment, the lower surface of the collection box 29 is provided with two symmetrical sliding rods 10. The sliding rods 10 are fixedly connected to the mounting cylinders 24. The two mounting cylinders 24 are connected to the rotating rod 20 through the bearing. Friction wheels 19 are fixedly connected to both ends of the rotating rod 20. Three annular inclined grooves 21 are opened on the circumference of the rotating rod 20. Three reciprocating sliders 22 are slidably connected through the rotating rod 20. The three reciprocating sliders 22 correspond to the three annular inclined grooves 21 respectively. The reciprocating sliders 22 are provided with an eccentric shaft 31. The eccentric shaft 31 is slidably connected to the inner wall of the annular inclined groove 21. The reciprocating sliders 22 are rotatably connected to the rope block cylinder 33 through the pin. The rope block cylinder 33 is slidably connected to the telescopic block 32. The side wall of the collection box 29 is provided with a T-shaped block groove. Several T-shaped blocks 30 are slidably connected to the inner wall of the T-shaped block groove. Several T-shaped blocks 30 are fixedly connected to the reciprocating plate 18. The reciprocating plate 18 is detachably connected to the scraper 17.

[0042] As the lifting box 5 rises, the friction wheel 19 rotates upon contact with the wall. The rotation of the friction wheel 19 drives the rotating rod 20 to rotate. The annular groove 21 of the rotating rod 20 cooperates with the eccentric shaft 31, causing the reciprocating slider 22 to move laterally back and forth on the rotating rod 20. The reciprocating slider 22 drives the reciprocating plate 18 to move back and forth through the telescopic block 32 and the rope block tube 33. The reciprocating plate 18 drives the scraper 17 to move back and forth, improving the cleaning effect of the scraper 17 on small stones attached to the wall.

[0043] In one embodiment, two symmetrical guide blocks 37 are fixedly connected to the lower surface of the collection box 29, and the sliding rod 10 is slidably connected to the guide blocks 37. A first limiting plate 38 and a second limiting plate 39 are fixedly connected to the side wall of the sliding rod 10, and a spring is fixedly connected between the second limiting plate 39 and the guide blocks 37.

[0044] The friction wheel 19 is always in contact with the wall by the spring and the second limiting plate 39.

[0045] In one embodiment, the rotating rod 20 is provided with two symmetrical eccentric shafts 31. The eccentric shafts 31 are rotatably connected to the first connecting rod 28. The end of the first connecting rod 28 away from the eccentric shafts 31 is rotatably connected to the second connecting rod 34 via a pin. Two symmetrical water tanks 36 are fixedly connected to the lower surface of the collection box 29. The second connecting rod 34 is slidably connected to the water tank 36. The end of the second connecting rod 34 located inside the water tank 36 is fixedly connected to a piston block 35. The piston block 35 is slidably connected to the inner side wall of the water tank 36. A water tank 25 is fixedly connected to the inner side wall of the collection box 29. Several spray heads 27 are provided on the side wall of the water tank 25. A connecting pipe 26 is connected between the water tank 25 and the water tank 36. A one-way valve is provided on the connecting pipe 26. A water inlet pipe 23 is provided on the side wall of the water tank 36. A one-way valve is provided on the water inlet pipe 23.

[0046] The rotation of the rotating rod 20 drives one end of the first connecting rod 28 to rotate along with the eccentric shaft 31, causing the second connecting rod 34 to reciprocate. The reciprocating movement of the second connecting rod 34 drives the piston block 35 to reciprocate. When the piston block 35 moves backward, it draws external water into the water tank 36 through the water inlet pipe 23. When the piston block 35 moves forward, it squeezes the water drawn into the water tank 36 into the water tank 25 through the connecting pipe 26, and sprays it out through the spray head 27 of the water tank 25.

[0047] Since the scraper 17 will scatter dust on the wall when cleaning small stones, water is sprayed through the spray head 27 to suppress the dust, prevent the dust from scattering in the air and affecting the construction environment, and also prevent the dust from coming into contact with the plaster and affecting the plaster quality.

[0048] In one embodiment, a distance measuring device 6 is installed on the side wall of the guide rail frame 4. The distance measuring device 6 is activated, and the distance between the device and the wall is adjusted.

[0049] In one embodiment, a positioning rod 3 is provided on the side wall of the base 1. The positioning rod 3 is used to position and fix the device, preventing the device from moving during the plastering process.

[0050] The above embodiments disclose an intelligent building painting device, the specific working principle and process of which are as follows:

[0051] S1: First, move the painting device to the area to be plastered using the casters 2, turn on the rangefinder 6, adjust the distance between the device and the wall, and then fix the device in place using the positioning rod 3 to prevent the device from moving during the plastering process.

[0052] S2: The worker first uses a shovel to send the plaster onto the loading plate 8. Then, the second motor 12 is started. The second motor 12 drives the gear 13 to rotate. The gear 13 and the rack 14 work together to make the lifting box 5 rise along the guide rail of the guide frame 4. The electric push rod inside the lifting box 5 is gradually started. The electric push rod drives the loading plate 8 to rotate gradually, and the plaster on the loading plate 8 is gradually poured onto the plastering plate 9, so that the plaster is evenly applied to the wall.

[0053] S3: As the lifting box 5 rises, it also lifts the collection box 29. During the rise of the collection box 29, the scraper 17 cleans up the small stones protruding from the wall, and the cleaned stones fall into the collection box 29.

[0054] When the plaster layer dries and shrinks, avoid creating stress concentration points around small stones, as this can cause the mortar to shrink at different rates than other parts, resulting in cracks.

[0055] S4: As the lifting box 5 rises, the friction wheel 19 rotates in contact with the wall. The rotation of the friction wheel 19 drives the rotating rod 20 to rotate. The annular groove 21 of the rotating rod 20 cooperates with the eccentric shaft 31, which drives the reciprocating slider 22 to move laterally back and forth on the rotating rod 20. The reciprocating slider 22 drives the reciprocating plate 18 to move back and forth through the telescopic block 32 and the rope block tube 33. The reciprocating plate 18 drives the scraper 17 to move back and forth, which improves the cleaning effect of the scraper 17 on the small stones attached to the wall.

[0056] S5: At the same time, the rotation of the rotating rod 20 drives one end of the first connecting rod 28 to rotate along with the eccentric shaft 31, causing the second connecting rod 34 to reciprocate. The reciprocating movement of the second connecting rod 34 drives the piston block 35 to reciprocate. When the piston block 35 moves backward, it draws external water into the water tank 36 through the water inlet pipe 23. When the piston block 35 moves forward, it squeezes the water drawn into the water tank 36 into the water tank 25 through the connecting pipe 26, and sprays it out through the spray head 27 of the water tank 25.

[0057] Since the scraper 17 will scatter dust on the wall when cleaning small stones, water is sprayed through the spray head 27 to suppress the dust, prevent the dust from scattering in the air and affecting the construction environment, and also prevent the dust from coming into contact with the plaster and affecting the plaster quality.

[0058] The friction wheel 19 is always in contact with the wall by the spring and the second limiting plate 39.

[0059] The water tank 36 has a large space inside for the piston block 35 to move, preventing the second limiting plate 39 from working with the spring to drive the friction wheel 19 and the rotating rod 20 to move horizontally, thus affecting the reciprocating movement of the piston block 35 inside the water tank 36.

[0060] S6: After cleaning is completed, the first motor 11 is started. The first motor 11 drives the collection box 29 to rotate through the rotating frame 16. The rotation of the collection box 29 dumps the sand and gravel inside for centralized processing.

[0061] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
