Description

Technical Field

[0001] This invention relates to the field of wall repair technology, specifically to a wall brick repair and coating device for the restoration of ancient buildings. Background Technology

[0002] When restoring the walls of ancient buildings, it is necessary to apply cement or other spray materials to the surface of the wall tiles. Traditional construction methods use large-scale painting machines that simply press the spray material onto the wall surface or into the gaps. This monotonous application process makes it difficult to penetrate deep into the gaps between the tiles, resulting in weak adhesion between the spray material and the repaired tiles. This makes the spray material loose and insufficiently compact after hardening. Furthermore, most painting machines are bulky and complex, making them inconvenient to move and store. This is one reason why such machines cannot be widely adopted. In addition, simple manual application tools are inefficient, resulting in significant paint waste. Uneven application pressure and varying amounts of material can also lead to uneven thickness of the spray material in the tile gaps, making it difficult to control the quality of the mortar application. Besides significantly impacting the aesthetics of the wall, spray material drips onto clothing during construction, posing a significant safety hazard. Moreover, with the increasing cost of labor, hiring a skilled painter is becoming increasingly expensive. Therefore, this expensive, inefficient, and ineffective method of painting walls urgently needs improvement.

[0003] To overcome the shortcomings and inconveniences of machine-based wall coating equipment, this invention designs a wall tile repair coating device for ancient building restoration. This addresses the inconvenience and limited coating action of existing wall coating machines mentioned in the background section. The invention features a simple structure, strong practicality, and convenient operation. It allows for longitudinal and lateral movement during coating, ensuring even pressure on the sprayed material within the tile gaps while cleaning them. This effectively solves the problem of loose and unstable sprayed material, thus improving coating efficiency. Summary of the Invention

[0030] Please see Figure 1-10 This invention provides a technical solution: a wall tile repair and coating device for ancient building restoration. The front of the box 1 is equipped with a material storage mechanism, which is connected to the coating tube mechanism through a material conveying hose 12. The pushing mechanism is connected to the coating tube mechanism and the dust removal tube mechanism through a telescopic rod 13. The back panel of the box 1 is symmetrically equipped with support leg assemblies for supporting single wall tiles. Each support leg assembly includes a fixed leg mechanism for supporting one side of the wall tile, a sliding leg mechanism for opening the gap between adjacent wall tiles, and an adsorption leg mechanism. The pushing mechanism is provided with a plug-in mechanism for switching connection with the coating mechanism and the dust removal mechanism respectively. The front and rear panels of the box 1 are provided with a main slide groove for the coating tube mechanism and the dust removal tube mechanism to slide up and down. The coating tube mechanism and the dust removal tube mechanism are housed on the upper and lower sides of the main slide groove.

[0031] During operation, select the wall surface to be repaired and load appropriate spray material into the storage bin 14. First, smooth the gaps in the wall brick surface, remove dust, polish, and blow air. Move the dust removal pipe 23 to the middle main handle 11 position. Insert the telescopic rod 13 into the dust removal pipe 23, and they will engage, allowing them to move together in a fixed position. Move the coating pipe 2 to the uppermost circular gap to lock it in place. Remove the material delivery hose 12 from the coating pipe 2 and return it to the inlet 15 to prevent the spray material from leaking out during dust removal. Insert the dust removal pipe 23 into the actuating block 4 to begin dust removal. Fix the leg 2. 1. Press the main handle 11 firmly against the damaged wall to be repaired. Manually push the auxiliary handle 3 up and down to move the two main racks 31 up and down. The flat gear 34 and coaxial bevel gear 35 rotate, causing the lead screw bevel gear 36 and rolling lead screw 37 to rotate. The rolling lead screw 37 is threaded with a lead screw slider 38, which is slidably locked inside the housing 1. The lead screw slider 38 moves left and right, thereby increasing the gap between the repaired wall tiles. At this time, push and press the main handle 11 up and down. The dust removal pipe 23 head is aligned with the increased gap to grind and clean the dust. At the same time, the dust removal pinion 61 and the auxiliary racks... 25 meshes to achieve rotation, thus the fan 63 rotates, and the blower air flows out from the gaps, accelerating the cleaning of residual dust in the gaps. After dust removal is completed, the dust removal pipe 23 is pulled out of the telescopic rod 13 and slid to the slot below the box to fix it. The upper slot coating pipe 2 is engaged and fixed with the telescopic rod 13. The material conveying hose 12 is inserted into the telescopic rod 13, and the coating pipe 2 is inserted into the actuating block 4 to perform the coating work. Pushing the auxiliary handle 3 up and down drives the two main racks 31 to move up and down, thereby driving the flat gear 34 and the coaxial bevel gear 35 to rotate, causing the lead screw bevel gear 36 and the rolling lead screw 37 to rotate. A lead screw slider 38 is threaded onto the rod 37. The lead screw slider 38 is slidably locked inside the housing 1. The lead screw slider 38 moves left and right to increase the gap between the repaired wall tiles. Pushing the main handle 11 again, the spray material enters the material delivery hose 12 from the storage bin 14, is transmitted to the telescopic rod 13, and is finally delivered to the cavity of the coating tube 2 by the feeding pipe 5. While the main handle 11 slides, the coating pinion 52 meshes with the secondary rack 25 and rotates, realizing the rotation of the spiral blade 55, thereby conveying the spray material to the coating head 56 and flowing out to the gap between the wall tiles. Repeatedly moving the coating tube 2, the spray material is evenly repaired to the damaged wall.

[0032] As a further embodiment of the present invention, the storage mechanism includes a storage bin 14 fixed to one side of the housing 1, the storage bin 14 being connected to the conveying hose 12, and the surface of the storage bin 14 being provided with a 15 for replenishing materials;

[0033] During operation, the user loads an appropriate amount of wall tile paint into the storage bin 14. The paint is conveyed through the conveying hose 12 to the telescopic rod 13 and then into the coating pipe 2. The paint is replenished from the inlet 15. One end of the conveying hose 12 connected to the telescopic rod 13 can be pulled out and retracted to the inlet 15, making it easy for the telescopic rod 13 to switch between the coating pipe 2 and the dust removal pipe 23.

[0034] As a further embodiment of the present invention, the pushing mechanism includes a main handle 11, with branch rods connected to both sides of the main handle 11. The branch rods are slidably mounted on the surface of the housing 1. The bottom of the main handle 11 is connected to the 13. The 12 passes through the telescopic rod 13 and communicates with the applicator tube mechanism.

[0035] During operation, move the coating tube 2 or dust removal tube 23 to the middle of the main slide groove and attach the rear limit lock to the telescopic rod 13. The two are fixed and move together. Manually push the main handle 11 up and down. The main handle 11 drives the coating tube 2 or dust removal tube 23 to slide up and down in the main slide groove of the box 1.

[0036] As a further embodiment of the present invention, the fixing leg mechanism includes a fixing leg 21, which is fixed on both sides of the back of the box 1 for adsorbing and supporting two adjacent wall bricks respectively. The outer end of the fixing leg 21 is provided with an elastic frustum-shaped suction cup.

[0037] When working, the user determines that the wall tile gaps in a certain wall area need to be smoothed or sprayed, and tries to make the left and right sides of the machine flush with the wall. Then, the fixing leg 21 is attached to the two wall tiles to strengthen the fixation of the wall tiles, and the coating tube 2 or dust removal tube 23 is aligned with the gap between the two wall tiles to facilitate the work.

[0038] As a further embodiment of the present invention, the sliding leg mechanism includes a sliding leg 24 and a secondary handle 3. The secondary handle 3 is located outside the housing 1, and a pull rod 30 is fixedly connected to the secondary handle 3. The pull rod 30 is slidably inserted into the side wall of the housing 1. A fixing plate 32 is fixedly installed inside the housing 1. A movable main rack 31 is slidably installed on the back of the fixing plate 32. The inner end of the pull rod 30 is fixedly connected to the main rack 31. A bearing bracket 33 is fixed to the side wall of the fixing plate 32. A spur gear 34 is rotatably mounted on the main rack 31 for meshing with it. A coaxial bevel gear 35 is coaxially mounted on the spur gear 34. A lead screw bevel gear 36 for meshing is provided on one side of the coaxial bevel gear 35. The lead screw bevel gear 36 is mounted on the end of the rolling lead screw 37. The rolling lead screw 37 is rotatably mounted inside the housing 1. A lead screw slider 38 is threaded onto the rolling lead screw 37. The lead screw slider 38 is slidably locked inside the housing 1. The sliding leg 24 is fixedly connected to the lead screw slider 38.

[0039] During operation, the main body of the mechanism is kept parallel to the wall to be repaired, and the fixed leg 21 is pressed tightly against the damaged wall to be repaired. The auxiliary handle 3 is manually pushed up and down to drive the two main racks 31 to move up and down, thereby driving the flat gear 34 and the coaxial bevel gear 35 to rotate, causing the lead screw bevel gear 36 and the rolling lead screw 37 to rotate, and the lead screw slider 38 to move, thereby causing the sliding leg 24 to move to the left and right directions respectively. Because the suction cup at the front end of the sliding leg 24 is attached to the wall bricks, it will increase the gap between the repaired wall bricks.

[0040] As a further embodiment of the present invention, the adsorption leg mechanism includes an adsorption leg 22, a fixing block 40 is fixed to the inner end of the adsorption leg 22, a crossbar 41 perpendicular to the adsorption leg 22 is fixedly connected to the fixing block 40, the crossbar 41 is slidably inserted into the inside of the housing 1, a spring 42 for resetting the crossbar 41 is provided between the inner wall of the housing 1 and the fixing block 40, and a toggle block 4 for slidingly engaging with the inner end of the crossbar 41 is slidably installed on one side of the main rack 31, and two adjacent toggle blocks 4 form a clamping part for clamping the coating tube mechanism or the dust removal tube mechanism;

[0041] During operation, the coating tube 2 or dust removal tube 23 is inserted into the actuating block 4, and the main handle 11 is pressed from the rear. The rear side of the actuating block 4 is connected to the main rack 31, and the two are connected by a track groove to slide. When the actuating block 4 slides up and down, it passes through the middle abutting end of the crossbar 41, which causes the spring 42 to be compressed and shortened. When the actuating block 4 leaves the end of the crossbar 41, the spring 42 returns to its original position, thereby fixing the block 40 and the suction leg 22 to return to their original positions. During this repeated process, the suction leg 22 moves left and right, and the suction cup at the front end of the suction leg 22 adheres to the wall tile. During operation, the gap between the wall tile is appropriately enlarged to improve the utilization rate of the paint and reduce waste.

[0042] As a further embodiment of the present invention, the coating tube mechanism includes a coating tube 2. The inner cavity of the coating tube 2 is divided into a front cavity and a rear cavity by a partition plate 54. A feeding shaft 50 is rotatably installed inside the coating tube 2, penetrating the front cavity and the rear cavity. A spiral blade 55 is fixedly installed on the rod wall inside the front cavity of the feeding shaft 50. A coating flat gear 51 is fixedly installed on the rod wall inside the rear cavity of the feeding shaft 50. A gear opening communicating with the rear cavity is opened on the side wall of the coating tube 2. A coating pinion 52 for meshing with the coating flat gear 51 is rotatably installed in the gear opening through a coating gear shaft 53. A feeding tube 5 communicating with the front cavity is connected inside the coating tube 2. The feeding tube 5 is communicating with the telescopic rod 13. A coating head 56 for extruding material is opened at the front end of the coating tube 2. A secondary rack 25 for meshing with the coating pinion 52 is installed on one side of the main chute.

[0043] During operation, after dust removal and cleaning, the telescopic rod 13 is pulled out from the rear end of the dust removal pipe 23, and the dust removal pipe 23 is slid to the slot below the housing 1 and pushed to the rear slot, where it is fixed by the outer wall of the dust removal pipe 23. The coating pipe 2 and the main handle 11 are engaged from the upper slot, and the coating pipe 2 is then inserted into the actuating block 4. Since there is a spring connection between the actuating block 4 and the main rack 31, the coating pipe 2 is in contact with the main handle 31, and the coating work begins. The spray material enters the material delivery hose 12 from the storage bin 14, then goes to the telescopic rod 13, and finally is delivered from the feeding pipe 5 to the front cavity of the coating pipe 2. While the main handle 11 slides up and down, the coating pinion 52 meshes with the secondary rack 25 and rotates. The coating spur gear 51 and the feeding shaft 50 rotate accordingly, and the spiral blade 55 delivers the spray material, which flows out from the orifice of the coating head 56 into the gaps between the wall tiles. The coating pipe 2 is moved repeatedly to ensure that the spray material is evenly used to repair the damaged wall.

[0044] As a further embodiment of the present invention, the dust removal pipe mechanism includes a dust removal pipe 23, a dust removal shaft 6 that penetrates the cavity is rotatably installed inside the dust removal pipe 23, a fan 63 is fixedly installed at the front end of the dust removal shaft 6, a dust removal flat gear 60 is fixed on the rod wall of the dust removal shaft 6, a gear opening is provided on the side wall of the dust removal pipe 23, a dust removal pinion 61 for meshing with the dust removal flat gear 60 is rotatably installed in the gear opening through a dust removal gear shaft 62, and a 25 for meshing with the dust removal pinion 61 is installed on one side of the main slide groove;

[0045] During operation, the dust removal pipe 23 is moved to the middle main handle 11 position. The tail of the dust removal pipe 23 and the telescopic rod 13 have interlocking slots. After the telescopic rod 13 is inserted into the dust removal pipe 23, the two move together in a fixed manner. At this time, the main handle 11 is moved up and down, so that the dust removal pipe 23 is engaged with the actuating block 4. The actuating block 4 clamps the dust removal pipe 23. The main handle 11 is pressed from the rear and moved up and down. The grinding tooth block 26 is used to grind the gaps, thereby cleaning the dust and brick joints. While the main handle 11 slides up and down, the dust removal pinion 61 meshes with the secondary rack 25 of the housing 1. The dust removal pinion 61 and the dust removal spur gear 60 rotate. The fan 63 is installed at the top of the dust removal shaft 6. The fan 63 rotates and blows air out from the gaps. The dust removal pipe 23 is moved repeatedly to accelerate the cleaning of residual dust after the gaps are cleaned.

[0046] As a further embodiment of the present invention, the rear ends of the coating tube mechanism and the dust removal tube mechanism can be fixedly connected to the telescopic rod 13 through the limiting slot;

[0047] During operation, the dust removal tube 23 or the coating tube 2 is moved to the middle main handle 11 position.
