The spray nozzle 20 is installed in a forward and backward telescopic manner, and can be adjusted according to the depth of the spray surface during the spraying operation, which is convenient for the corresponding process to be used later.

[0042] The movable support 1 is connected to the top of the lifting support seat 25 through a connecting piece 24, a lifting connecting rod mechanism 26 is arranged below the lifting support seat 25, a bottom movable platform 27 is installed at the bottom of the lifting connecting rod mechanism 26, and a self-propelled wheel 28 and a lifting reinforcement support seat 29 are arranged below the bottom movable platform 27. The self-propelled wheel 28 can be self-driven and equipped with a motor drive, and the lifting connecting rod mechanism 26 can provide support for the height adjustment of the movable support 1. When another embodiment of the present invention is in operation, a universal wheel 34 with a brake is installed at the bottom of the movable support 1. The universal wheel 34 with a brake can be self-driven and equipped with a motor drive and a wheel brake control device. This embodiment is suitable for use when the wall position of an ancient building is relatively low.

[0043] During specific operation, the distance and height between the movable support 1 and the ancient building wall 35 are adjusted accordingly according to the position of the area 36 to be repaired on the ancient building wall 35. Specifically, according to the height position of the area 36 to be repaired, the movable support 1 is driven by the self-propelled wheel 28 or the universal wheel 34 with brake to move to the position near the ancient building wall 35. When the height of the area 36 to be repaired is relatively high, the movable support 1 with the lifting connecting rod mechanism 26 is used. When the height of the area 36 to be repaired is relatively low, the movable support 1 with the universal wheel 34 with brake is used.

[0044] After the position is adjusted, the area of ​​the area to be repaired 36 is measured by the camera 13, and the product is moved to the center line of the area to be repaired 36 according to the measured area value. Then the cutting operation is performed first. Specifically, the cutting device is clamped on the clamp 15, and then the remote control device is turned on through the auxiliary monitoring of the camera 13, and the straight stubble contour cutting operation with matching edges is performed on the area to be repaired 36. During the cutting process, the controller controls the start of the stepper motor 9 to drive the chain 10 to realize the longitudinal lifting of the lifting cross bar 11. The controller controls the electric drive travel wheels of the multifunctional self-propelled repair trolley 12 to realize the lateral movement of the multifunctional self-propelled repair trolley 12 on the lifting cross bar 11. The controller drives the rotary start motor to realize the rotation of the electric rotating seat 14. The above-mentioned lateral, longitudinal and rotational movement operations can be performed on

[0045] The cutting trajectory is controlled in all directions to realize the cutting operation according to the preset path. When the straight stubble contour cutting operation is in progress, it is necessary to ensure that the horizontal and vertical cutting lines are perpendicular to each other. When the straight stubble contour cutting operation is completed, the edge position of the contour is set in a vertical or horizontal shape. After the cutting device is completed, there is a certain curvature at the vertical and horizontal intersections of the inner side of the straight stubble contour. At this time, leveling operation is required, and when the leveling operation is in progress, the inner side of the straight stubble contour needs to be leveled. Due to the different degrees of wall peeling and damage, unified leveling is required, which is also conducive to forming a closer combination with the wall after the base material is filled in the later stage.

[0046] After completing the straight stub contour cutting operation, remove the cutting device from the fixture 15 and replace it with the clamping grinding device, and perform grinding and leveling operations on the inner wall of the straight stub contour. Different joints are set on the grinding device to achieve overall grinding and leveling of the corner positions of the straight stub contour, and to achieve the regularity of the inner cavity of the straight stub contour, which is convenient for the subsequent installation of the mold box 37. When the straight stub contour cutting and grinding leveling operations are in operation, turn on the atomizing water nozzle 19 to provide visual dust reduction for the remote image acquisition of the camera 13, so that the camera 13 can obtain a clear picture of the working area in real time.

[0047] After completing the grinding and leveling operation, turn on the air blowing nozzle 21 to perform soot blowing cleaning operation on the inner cavity of the straight cut profile, then turn on the atomizing water nozzle 19 again to perform water sprinkling cleaning, and wet the bricks on the outer wall of the wall in the straight cut profile area. After the grinding and leveling operation is completed, although spray dust reduction is used, powder is still easy to remain in the corners of the inner cavity of the straight cut profile. The soot blowing method is adopted first to fully clean the inner cavity of the straight cut profile, which is helpful for the fitting installation of the mold box 37 later, and also helps the combination of the base material and the vertical wall surface of the inner cavity of the straight cut profile. The water sprinkling cleaning operation can fully moisten the vertical wall surface of the inner cavity of the straight cut profile and improve the adhesion between the base material and the wall.

[0048] After completing the above steps, the shape, side length and depth of the straight stubble profile are measured by the camera 13, and a mold box 37 that matches the inner diameter of the straight stubble profile is produced according to the measured data. After the mold box 37 is produced, it can fully fit the inner diameter of the straight stubble profile, and the depth of the straight stubble profile is not less than the width of the mold box 37. After the mold box 37 is installed, the rear of the mold box 37 fully fits the wall after the flattening operation, and the front side of the mold box 37 is located 2 cm from the opening position of the straight stubble profile, and a filling position is reserved for the surface anti-corrosion hardening layer 40. A criss-cross reinforced support frame 38 is set inside the mold box 37, and then a steel mesh 39 is installed between the reinforced support frame 38 and the inner wall of the mold box 37. The mold box 37 adopts a reinforced structure, and the repaired area 36 to be repaired is supported as a whole, and the reinforced support frame 38 is used to implement reinforced support, and finally the steel mesh 39 is installed to facilitate the sticking and hanging of the base material and improve the anti-falling performance after repair.

[0049] After completing the above steps, start the electric telescopic rod 33, drive the telescopic frame 32 and the spray nozzle 20 to penetrate into the inner cavity of the straight stubble contour, and implement the base material spray filling operation on the inner cavity of the mold box 37. After the spray filling is completed, the filled base material is smoothed again by the grinding device so that the outer side of the base material is flush with the outer side of the mold box 37. The 2 cm depth between the outer side of the mold box 37 and the outer side of the ancient building wall 35 is the spray thickness of the surface corrosion-resistant hardening layer 40.

[0050] After completing the above steps, a layer of adhesive layer is sprayed on the surface of the fully dried and solidified base material through the spray nozzle 20. After the adhesive layer is dried, the surface anti-corrosion hardening layer 40 is sprayed on the outer wall of the adhesive layer in the inner cavity of the straight stubble profile through the spray nozzle 20, and a smoothing treatment that matches the outer surface of the ancient building wall 35 is performed, and then the seams are rushed and made. After the surface anti-corrosion hardening layer 40 solidifies, it is polished and colored. When the color-matching operation is running, the original brick body cut off during the straight stubble profile cutting process can be used to mix and make a color-matching surface slurry or coating, and the anti-corrosion colloid is mixed to perform the color-matching transformation operation, and the edge position of the straight stubble profile after filling is covered with the original wall box to achieve a complete and identical repair effect.
