Description

Technical Field

[0001] The present invention relates to the field of building construction, and particularly to a painting robot for building construction. Background Art

[0002] The painting construction of building facades is an efficient construction method that evenly covers the building exterior with paint through spraying equipment to achieve purposes such as decoration, protection, and waterproofing. Compared with traditional roller coating or brush coating, spraying construction has higher efficiency and a more uniform coating, and is particularly suitable for large-area operations.

[0003] A painting robot for building construction is a robot used to efficiently and safely complete the spraying operation of building facades. For example, the exterior wall spraying robot developed by Bozhilin is an automated construction equipment mainly used for the spraying operation of coatings such as latex paint and multicolored paint on building facades. This robot realizes efficient and precise spraying through intelligent technology, significantly improving construction efficiency and reducing the risk of manual high-altitude operations.

[0004] When spraying, due to their generally large volume, spraying robots can effectively spray the outer side of relatively wide walls. However, when there are adjacent spraying surfaces in a building (such as a main wall that has been sprayed and a wing wall to be treated), it is necessary to replace the spraying robot with a new size or perform spraying manually, resulting in low flexibility.

[0005] Therefore, it is necessary to provide a new painting robot for building construction to solve the above technical problems. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a painting robot for building construction, which solves the problem of low flexibility that when there are adjacent spraying surfaces in a building, it is necessary to replace the spraying robot with a new size or perform spraying manually.

[0007] The painting robot for building construction provided by the present invention includes a body, the body is suspended on one side of the building through a suspension assembly on the roof, a two-stage motion mechanism is arranged on the body, a moving seat is slidably arranged on the two-stage motion mechanism, a support column is movably arranged on the moving seat, a swing seat is fixed on the support column, a support seat is fixed on the swing seat, a chute is opened on the support seat, a sliding seat is slidably arranged inside the chute, a first mounting shaft is movably arranged on the sliding seat, and an automatic spraying gun is installed at the top of the first mounting shaft.

[0008] In a preferred embodiment, an adjusting gear is installed at the top of the support column, a cylinder is installed on one side of the moving seat, an adjusting rack is installed at the output end of the cylinder, and the adjusting rack meshes with the adjusting gear.

[0009] In a preferred embodiment, a translation screw rod is movably arranged inside the sliding groove, and the translation screw rod penetrates through the bottom of the sliding seat and is in threaded connection with the sliding seat; An adjusting motor is installed on the swinging seat, and one end of the translation screw rod extends out of the support seat and is connected with the output end of the adjusting motor through a coupling.

[0010] In a preferred embodiment, the translation screw rod is galvanized.

[0011] In a preferred embodiment, a round block is fixed on the first mounting shaft, and a plurality of first engaging teeth are fixedly arranged at intervals on the round block. A side seat is fixed on the sliding seat, a sliding rod penetrates through the side seat, and a second engaging tooth is fixed on the sliding rod. The second engaging tooth is located between the two first engaging teeth.

[0012] In a preferred embodiment, a pulling plate is fixed on the sliding rod, a limiting spring is sleeved on the sliding rod, one end of the limiting spring is fixed on the side seat, and the other end of the limiting spring is fixed on the pulling plate.

[0013] In a preferred embodiment, two limiting seats are fixedly arranged at intervals on one side of the moving seat, a second mounting shaft is movably arranged between the two limiting seats, and a support rod is fixed on the second mounting shaft. The swinging seat can be supported by the support rod.

[0014] In a preferred embodiment, a connecting shaft is arranged on one side of the limiting seat. One end of the connecting shaft is fixedly connected with the second mounting shaft, and a driving worm gear is installed at the other end of the connecting shaft; Two fixed seats are fixedly arranged at intervals on one side of the limiting seat, a driving worm is movably arranged between the two fixed seats, and the driving worm is meshed with the driving worm gear; A support motor is installed on one side of the moving seat, and one end of the driving worm extends out of the fixed seat and is connected with the output end of the support motor through a coupling.

[0017] Advantages of the present invention: When the present spraying robot is used, the whole body can be suspended to one side of the wall through the suspension assembly. When spraying the wall on this side, under the action of the two-stage motion mechanism, the whole moving seat will be driven to move (keep horizontal with the wall to be processed), and when moving, the automatic spraying gun will spray the wall; After the above-mentioned wall is sprayed, since the spraying robot cannot be placed on one side wall adjacent to it due to the small space, the staff can move the body to the uppermost position through the suspension assembly, adjust the position of the moving seat through the two-stage motion mechanism, and then the staff can rotate the first mounting shaft according to the orientation of the wall to be sprayed to adjust the spraying direction of the automatic spraying gun. After the orientation of the automatic spraying gun is adjusted, the air cylinder is started to drive the entire swing seat to change from the horizontal posture to the vertical posture. After the adjustment is completed, the suspension assembly is started to drive the entire body to move downward. During the downward movement of the body, the automatic spraying gun can spray the wall to be processed. During the spraying process, the translation screw driven by the adjustment motor will drive the sliding seat to slide along the sliding groove, ensuring that the automatic spraying gun can completely spray the wall to be processed, improving its application range and flexibility, and reducing the cost.

[0020] The present invention will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , where Figure 1 is the main structure stereo view of the construction painting robot provided by the present invention Figure 1 ; Figure 2 is Figure 1 the enlarged structural schematic diagram of A shown in Figure 3 is Figure 1 the enlarged structural schematic diagram of B shown in Figure 4 is the main structure stereo view of the construction painting robot provided by the present invention Figure 2 ; Figure 5 is the side view of the main structure of the construction painting robot provided by the present invention; Figure 6 is the top view of the main structure of the construction painting robot provided by the present invention.

[0022] In the specific implementation process, as Figures 1 - 6 shown, it includes a body 1, on which a two-stage motion mechanism 2 is provided. A spraying assembly and a corresponding control assembly are also provided on the body 1. The body 1 is suspended on one side of the building through a suspension assembly on the roof. The specific working principles of the suspension assembly, the spraying assembly, the control assembly, and the subsequent two-stage motion mechanism 2 are all mature technologies in the art and will not be elaborated here. Those skilled in the art can refer to the Bosch-Lin exterior wall latex paint spraying robot.

[0023] A moving seat 3 is slidably arranged on the two-stage motion mechanism 2. A drag chain 35 is arranged on the moving seat 3, and the drag chain 35 moves along with the moving seat 3. A paint supply pipeline and a power supply line are arranged inside the drag chain 35. A support column 4 is movably arranged on the moving seat 3. A swing seat 5 is fixed on the support column 4. A support seat 6 is fixed on the swing seat 5. A chute 7 is opened on the support seat 6. A sliding seat 8 is slidably arranged inside the chute 7. A first mounting shaft 9 is movably arranged on the sliding seat 8. An automatic spraying gun 10 is installed at the top of the first mounting shaft 9. When this spraying robot is in use, the entire body of the body 1 can be suspended to one side of the wall through the suspension assembly. When spraying one side of the wall, under the action of the two-stage motion mechanism 2, the entire moving seat 3 will be driven to move (keep horizontal with the wall to be processed). And when moving, the automatic spraying gun 10 will spray the wall. After spraying one side of the wider wall, the staff can start the two-stage motion mechanism 2 to drive the moving seat 3 to move to one side close to the subsequent wall to be processed (the shorter wall), and ensure that the swing seat 5 is kept horizontal with the wall to be processed after unfolding.

[0024] A side support rod 31 is fixed on the support column 4. The top of the side support rod 31 is fixed with a bottom plate 32. A top plate 34 is fixed on the bottom plate 32 through a number of vertical rods 33. During actual use, the bottom plate 32 can provide a supporting force for the paint supply pipeline and the power cord of the automatic spraying gun 10. The paint supply pipeline and the power cord are located in the space between the bottom plate 32 and the top plate 34, ensuring that they will not droop onto the two-stage moving mechanism 2.

[0025] A round block 16 is fixed on the first mounting shaft 9. A number of first cogs 17 are fixedly arranged on the round block 16 at intervals. A side seat 18 is fixed on the sliding seat 8. A sliding rod 19 is arranged through the side seat 18. A second cog 20 is fixed on the sliding rod 19. The second cog 20 is located between two first cogs 17. A pull plate 21 is fixed on the sliding rod 19. A limiting spring 22 is sleeved on the sliding rod 19. One end of the limiting spring 22 is fixed on the side seat 18, and the other end of the limiting spring 22 is fixed on the pull plate 21. During use, the pull plate 21 is pulled to drive the sliding rod 19 to move. After the second cog 20 driven by the sliding rod 19 disengages from between the two first cogs 17, the fixing of the position of the first mounting shaft 9 can be cancelled. At this time, the position of the first mounting shaft 9 can be adjusted. The spraying direction of the automatic spraying gun 10 is adjusted by rotating the first mounting shaft 9 according to the orientation of the wall surface to be sprayed. After the adjustment is completed, the pull plate 21 is released, and under the action of the limiting spring 22, the second cog 20 re-enters between the two first cogs 17 to complete the fixing of the position of the first mounting shaft 9.

[0026] An adjusting gear 11 is installed at the top of the support column 4. A cylinder 12 is installed on one side of the moving seat 3. The output end of the cylinder 12 is installed with an adjusting rack 13. The adjusting rack 13 is meshed with the adjusting gear 11. A translation lead screw 14 is movably arranged inside the chute 7. The translation lead screw 14 passes through the bottom of the sliding seat 8 and is threadedly connected thereto. The translation lead screw 14 is galvanized to improve its service life. An adjusting motor 15 is installed on the swing seat 5. One end of the translation lead screw 14 extends out of the support seat 6 and is connected to the output end of the adjusting motor 15 through a coupling. The translation lead screw 14 is galvanized to improve its service life. During the spraying process of adjacent working surfaces, the translation lead screw 14 driven by the adjusting motor 15 will drive the sliding seat 8 to slide along the chute 7, ensuring that the automatic spraying gun 10 can completely spray the wall surface to be processed.

[0027] On one side of the moving seat 3, two limiting seats 23 are fixedly arranged at intervals. A second mounting shaft 24 is movably arranged between the two limiting seats 23. A support rod 25 is fixed on the second mounting shaft 24. The support rod 25 can provide a supporting force for the swinging seat 5. On one side of the limiting seat 23, a connecting shaft 26 is arranged. One end of the connecting shaft 26 is fixedly connected to the second mounting shaft 24. A transmission worm gear 27 is mounted at the other end of the connecting shaft 26. On one side of the limiting seat 23, two fixed seats 28 are fixedly arranged at intervals. A transmission worm 29 is movably arranged between the two fixed seats 28. The transmission worm 29 meshes with the transmission worm gear 27. A support motor 30 is mounted on one side of the moving seat 3. One end of the transmission worm 29 extends out of the fixed seat 28 and is connected to the output end of the support motor 30 through a coupling. When the swinging seat 5 is unfolded from the horizontal state to the vertical state, the support motor 30 is started. Under the action of the transmission worm 29 and the transmission worm gear 27, the support rod 25 can rotate to a position in contact with the swinging seat 5 to provide a supporting force for it. A closed transmission is adopted between the transmission worm 29 and the transmission worm gear 27 to reduce wear and improve its service life.

[0028] The working principle of the present invention: When the present spraying robot is used, the entire body 1 can be suspended to one side of the wall through the suspension assembly. When spraying the wall on this side, under the action of the two-stage motion mechanism 2, the entire moving seat 3 will be driven to move (keep horizontal with the wall to be processed), and during the movement, the automatic spraying gun 10 will spray the wall; After the above-mentioned wall is sprayed, since the space on the adjacent side wall is too small to place the spraying robot, the staff can move the body 1 to the topmost position through the suspension assembly. The staff can rotate the first mounting shaft 9 according to the orientation of the wall to be sprayed to adjust the spraying direction of the automatic spraying gun 10. The specific process is to pull the pull plate 21 to drive the sliding rod 19 to move. After the sliding rod 19 drives the second engaging tooth 20 to disengage from between the two first engaging teeth 17, the fixing of the position of the first mounting shaft 9 can be cancelled. At this time, the position of the first mounting shaft 9 can be adjusted. After the adjustment is completed, the pull plate 21 is released. Under the action of the limiting spring 22, the second engaging tooth 20 re-enters between the two first engaging teeth 17 to complete the fixing of the position of the first mounting shaft 9; After adjusting the orientation of the automatic spraying gun 10, the air cylinder 12 is started to drive the adjusting rack 13 to move. Under the transmission action of the adjusting rack 13 and the adjusting gear 11, the entire swinging seat 5 changes from the horizontal posture to the vertical posture. After the adjustment is completed, the suspension assembly is started to drive the entire body 1 to move downward. During the downward movement of the body 1, the automatic spraying gun 10 can spray the wall to be processed. During the spraying process, the translation lead screw 14 driven by the adjusting motor 15 will drive the sliding seat 8 to slide along the sliding groove 7 to ensure that the automatic spraying gun 10 can completely spray the wall to be processed.
