Description

Technical Field

[0001] This invention relates to the field of wall reinforcement technology, and in particular to a plastering component and a wall plastering reinforcement device and method utilizing high-ductility concrete. Background Technology

[0002] When repairing cracked walls, a high-ductility concrete surface layer method can be used. This involves applying a 10-20mm thick layer of high-ductility concrete, utilizing its high toughness and crack resistance to improve the wall's overall integrity and seismic performance. No steel reinforcement is needed, and single-sided reinforcement is sufficient to meet seismic requirements. Traditional plastering involves workers manually applying mortar to the wall surface using plastering tools. This process is time-consuming, labor-intensive, inefficient, and the quality can vary depending on the worker's skill level.

[0003] While existing technologies include automatic wall plastering machines to replace manual labor, their operation involves filling the machine with concrete mortar, then using a scraper to apply the plaster upwards and then downwards in vertical strokes. However, after the machine finishes plastering one vertical surface, a bump appears at the junction between the two surfaces, requiring manual smoothing afterwards. This significantly wastes plastering efficiency and reduces the smoothness of the plaster. Furthermore, due to the limitations of the machine frame, existing scrapers cannot plaster from the bottom of the wall upwards (starting from the upper part of the bottom) or reach the top of the wall, resulting in incomplete plastering work and requiring manual touch-ups, further reducing plastering efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a plastering component and a wall plastering reinforcement device and method using high ductility concrete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A troweling assembly includes a movable base and a main scraper, and further includes: The lifting frame is provided in two sets and is placed on both sides of the movable base to drive the main scraper to move vertically along the wall.

The end of the housing away from the swinging plate is rotatably connected to the first sleeve, and the end of the elastic telescopic tube away from the swinging plate is fixedly connected to the main scraper.

[0009] Preferably, a pull rope is fixedly provided on the main scraper plate, and the end of the pull rope away from the main scraper plate passes through the elastic telescopic tube and the swing plate in sequence and is fixedly connected to the casing. A support rod is fixedly provided on the swing plate, and the pull rope is slidably connected to the support rod.

[0010] Preferably, the pushing assembly includes a side plate fixed to the U-shaped plate, a second lead screw rotatably connected to the side plate, a second sleeve threadedly connected to the second lead screw, an elastic telescopic plate movably disposed on the second sleeve, and a pusher seat movably connected to the end of the elastic telescopic plate away from the second sleeve. The pusher seat is slidably connected to the main scraper and moves against the auxiliary scraper. A secondary bevel gear is provided on the second lead screw, and a main bevel gear meshing with the secondary bevel gear is provided on the first lead screw.

[0011] Preferably, the auxiliary scraper includes a first plate body rotatably connected to the main scraper via a first pin and a second plate body rotatably connected to the first plate body via a second pin. A second torsion spring for driving the second plate body to reset and rotate is provided on the second pin. The pusher seat includes a first pusher seat movably connected to the elastic telescopic plate and a second pusher seat fixedly connected to the first pusher seat. The second pusher seat movably abuts against the second plate body.

[0012] Preferably, a connecting plate is fixed to the outside of the fixed base via a connecting plate, and the connecting plate is provided with a protrusion that moves against the end of the second plate.

[0013] A wall plastering and reinforcement device utilizing high-ductility concrete includes a plastering assembly and a guide rail. A movable base is slidably connected to the guide rail. A slurry storage tank is mounted on the movable base, and a material guide pipe is connected to the slurry storage tank. An mounting plate is fixed on a first sleeve, and a pump body is mounted on the mounting plate. The inlet end of the pump body is connected to the material guide pipe, and the outlet end of the pump body is connected to a slurry nozzle rotatably connected to the mounting plate. A second motor is fixed on the mounting plate, and a drive gear is connected to the output shaft of the second motor. A driven gear meshing with the drive gear is mounted on the slurry nozzle.

[0014] This invention also discloses a method for reinforcing walls using high-ductility concrete plastering, which involves applying a wall plastering reinforcement device using high-ductility concrete, and includes the following steps: S1: Place the reinforcement equipment in front of the wall to be reinforced, place the guide rail under the moving base, and control the lifting rod to push the moving base up until the top plate abuts against the floor above the wall. Fix the position of the processing equipment at this time. The main scraper is placed at an angle and the end closest to the wall is the high end. S2: Then control the winch and pump to work. The pump sprays the high ductility concrete in the slurry tank onto the wall to be plastered and reinforced through the slurry nozzle. As the winch moves the slide upward through the winding rope, the angle adjustment frame moves the main scraper upward with the slide. During this period, the main scraper performs preliminary plastering on the high ductility concrete sprayed on the wall. S3: When the main scraper is about to move to the top of the wall, control the pump to stop working. After the end of the main scraper near the wall moves to the top of the wall, control the first motor to run, so that the first screw rotates on the U-shaped plate, the first sleeve moves upward along the first screw axis, and the first sleeve drives the swinging part to rotate around the second pin as the center, changing the tilt angle of the main scraper so that the end of the main scraper near the wall is the bottom end; S4: When the first lead screw rotates, the main bevel gear meshes with the secondary bevel gear on the second lead screw. The second sleeve drives the pusher seat to move through the elastic telescopic plate, so that the pusher seat pushes the auxiliary scraper. The auxiliary scraper changes from being perpendicular to the main scraper to being placed horizontally with the main scraper, increasing the downward scraping width of the main scraper. During this period, the second pusher seat of the pusher seat limits the first plate and the second plate to prevent the first plate and the second plate from deflecting. Then, the first motor is controlled to stop running. S5: Then the winch releases the winding rope, and the slide slides down vertically under its own weight. The main scraper, together with the auxiliary scrapers on both sides, scrapes the high-ductility concrete after troweling, making the surface of the high-ductility concrete smooth, until the main scraper and the auxiliary scrapers scrape down to the position where the wall and the floor meet. S6: Then control the first motor to drive the first lead screw to rotate in the opposite direction, so that the first sleeve moves down along the first lead screw, readjusting the tilt state of the main scraper so that the main scraper can apply high ductility concrete to the top of the wall. When the first lead screw rotates, the second sleeve moves back, so that the pusher seat no longer applies a pushing force to the auxiliary scraper. The auxiliary scraper resets and rotates under the action of the torsion spring, and then the first motor stops running. S7: Then slide the movable base on the guide rail, adjust the wall plastering reinforcement area, repeat step S2, when the angle adjustment frame drives the main scraper to move up with the slide, the inclined downward second plate intermittently abuts against the protrusion, causing the second plate to shake relative to the main scraper, causing the high ductility concrete adhering to the second plate to fall off, repeat steps S3-S6 to achieve plastering reinforcement of another area of ​​the wall.

[0015] Compared with the prior art, the present invention provides a plastering component and a wall plastering reinforcement device and method using high-ductility concrete, which has the following beneficial effects: 1. The plastering component and the wall plastering reinforcement equipment and method using high-ductility concrete can adjust the tilt angle of the main scraper by placing an angle adjustment frame at the top or bottom of the wall. This allows for complete plastering reinforcement of a vertical surface of the wall from top to bottom or from bottom to top without the need for subsequent touch-up coating. It also improves plastering efficiency and reduces the waste of human resources.

[0016] 2. This plastering component and the wall plastering reinforcement equipment and method utilizing high-ductility concrete, by setting an auxiliary scraper, allows the auxiliary scraper to be placed horizontally with the main scraper when it moves down, increasing the scraping range of the main scraper. This enables the auxiliary scraper to smooth the vertical connecting protrusions at the edge of the main scraper. Furthermore, when the auxiliary scraper is subsequently retracted, the second plate of the auxiliary scraper intermittently abuts against the protrusions, causing the second plate to vibrate relative to the main scraper, shaking off the high-ductility concrete adhering to the second plate. This ensures that the subsequent auxiliary scraper effectively smooths the concrete protrusions in the edge area of ​​the main scraper, improving the smoothness of the plastering surface. No further adjustments by workers are required, reducing the waste of human resources.

[0017] 3. The plastering component and the wall plastering reinforcement equipment and method using high-ductility concrete, by causing the sleeve to slide relative to the swing plate, when the swing component drives the main scraper to rotate, the swing plate retracts into the sleeve, the sleeve applies tension to the pull rope, causing the pull rope to pull the elastic telescopic tube, the elastic telescopic tube retracts and drives the main scraper to rotate, the main scraper moves away from the wall surface when rotating, avoiding excessive compression of the high-ductility concrete on the wall when the main scraper rotates, thereby ensuring the smoothness of the wall plastering.

[0018] 4. The plastering component and the wall plastering reinforcement equipment and method using high-ductility concrete, by positioning the main scraper and auxiliary scraper with the first pusher and limiting the first plate and the second plate with the second pusher, ensures the flatness of the main scraper and auxiliary scraper when scraping downwards, and avoids the auxiliary scraper from loosening or lifting, which would affect the scraping effect on the high-ductility concrete.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] like Figures 1 to 3 As shown, this embodiment proposes a plastering assembly, including a movable base 1 and a main scraper 2, and further including: a lifting frame 3, an angle adjustment frame 4 and an auxiliary scraper 5. The lifting frame 3 is provided in two sets and is respectively placed on both sides of the movable base 1, for driving the main scraper 2 to move vertically along the wall. The angle adjustment frame 4 is provided on the lifting frame 3 for adjusting the tilt angle of the main scraper 2. The auxiliary scraper 5 is rotatably provided on the side of the main scraper 2 through a first pin shaft, for scraping off excess concrete mortar at the edge of the main scraper 2. A first torsion spring is provided on the first pin shaft for driving the auxiliary scraper 5 to reset and rotate. A pushing component is provided on the angle adjustment frame 4 for driving the auxiliary scraper 5 to be placed horizontally with the main scraper 2. The reinforcement equipment is placed in front of the wall to be reinforced. High-ductility concrete is then sprayed onto the wall surface. The main scraper 2 is tilted, with its end closest to the wall at the top. The lifting frame 3 moves the main scraper 2 upwards, allowing it to initially smooth the high-ductility concrete sprayed onto the wall from bottom to top. After the end of the main scraper 2 closest to the wall reaches the top, the angle adjustment frame 4 adjusts the tilt angle of the main scraper 2, making its bottom end. During this process, the pushing component automatically moves, causing the auxiliary scraper 5 to change from being perpendicular to the main scraper 2 to being horizontal, increasing the downward scraping width of the main scraper 2. The lifting frame 3 then moves both the main scraper 2 and the auxiliary scraper 5 downwards, smoothing the high-ductility concrete surface until they reach contact with the floor. The auxiliary scraper 5 can be used to completely reinforce a vertical wall surface from top to bottom or bottom to top without subsequent touch-ups, improving plastering efficiency and reducing manpower waste. The tilt of the main scraper 2 is then readjusted, with the end closest to the wall positioned at the higher end, allowing it to apply high-ductility concrete to the top of the wall. The auxiliary scraper 5 automatically resets, and the position of the movable base 1 is adjusted to adjust the reinforced area of ​​the wall surface. When the auxiliary scraper 5 moves down again, it effectively smooths out any concrete protrusions at the edge of the main scraper 2, improving the smoothness of the plaster surface. It should be noted that the auxiliary scraper 5 can be disassembled as needed. For example, when reinforcing the left or right edge of the wall, the left or right auxiliary scraper 5 can be removed to prevent collisions with the side wall when it moves down.

[0024] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the lifting frame 3 further includes a fixed seat 301, a movable seat 302, a lifting rod 303, a top plate 304, a support 305, a winch 306, a winding rope 307, and a slide 308. The slide 308 is slidably connected to the fixed seat 301 and the movable seat 302, and the angle adjustment frame 4 is fixedly connected to the slide 308. By controlling the lifting boom 303, the lifting boom 303 pushes the moving seat 302 upward until the top plate 304 abuts against the floor slab above the wall. This fixes the position of the processing equipment at this time. When performing the plastering and reinforcement work, the winch 306 is controlled to work. The winch 306 drives the slide 308 upward through the winding rope 307, causing the angle adjustment frame 4 to drive the main scraper 2 upward with the slide 308. During this period, the main scraper 2 performs preliminary plastering of the high-ductility concrete sprayed on the wall. When the end of the main scraper 2 near the wall moves to the wall... After the top of the wall is reached, the tilt angle of the main scraper 2 is adjusted by the angle adjustment frame 4 so that the end of the main scraper 2 closest to the wall is the bottom. Then, the winch 306 releases the winding rope 307, and the slide 308 slides vertically down under its own weight (a speed damper can be installed at the winch 306 to prevent sudden drop), making the high ductility concrete surface smooth until the main scraper 2 scrapes down to the position where the wall and the floor meet. This allows for complete plastering and reinforcement of a vertical surface of the wall from top to bottom or from bottom to top without the need for subsequent touch-up coating, thus improving plastering efficiency and reducing the waste of human resources.

[0025] like Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, in a preferred embodiment, based on the above method, the angle adjustment frame 4 further includes a U-shaped plate 401, a first lead screw 402, a first sleeve 403 and a swing member 404. A first motor 405 for driving the first lead screw 402 to rotate is fixed on the U-shaped plate 401, and the end of the swing member 404 away from the first sleeve 403 is connected to the main scraper 2. Furthermore, the swing component 404 includes a support plate 6, a swing plate 601, a housing 602, and an elastic telescopic tube 603. The end of the housing 602 away from the swing plate 601 is rotatably connected to the first sleeve 403, and the end of the elastic telescopic tube 603 away from the swing plate 601 is fixedly connected to the main scraper 2. When the angle adjustment frame 4 is working, by controlling the operation of the first motor 405, the first lead screw 402 rotates on the U-shaped plate 401, the first sleeve 403 moves up or down along the axis of the first lead screw 402, the first sleeve 403 drives the swing member 404 to rotate around the second pin, the sleeve 602 is displaced relative to the swing plate 601, changing the tilt angle of the main scraper 2, so that the end of the main scraper 2 closest to the wall is the bottom end or the high end.

[0026] like Figure 5 , Figure 6 and Figure 7As shown, in a preferred embodiment, based on the above method, a pull rope 7 is further fixed on the main scraper 2. The end of the pull rope 7 away from the main scraper 2 passes through the elastic telescopic tube 603 and the swing plate 601 in sequence and is fixedly connected to the housing 602. A support rod 6011 is fixed on the swing plate 601, and the pull rope 7 is slidably connected to the support rod 6011. When the swinging component 404 rotates around the second pin, the sleeve 602 slides relative to the swing plate 601. When the swinging component 404 drives the main scraper 2 to rotate, the swing plate 601 retracts into the sleeve 602. The sleeve 602 applies tension to the pull rope 7, causing the pull rope 7 to pull the elastic telescopic tube 603. The elastic telescopic tube 603 retracts and drives the main scraper 2 to rotate. When the main scraper 2 rotates, it moves away from the wall surface to avoid excessive compression of the high-ductility concrete on the wall, thereby ensuring the smoothness of the wall plastering. The elastic telescopic tube 603 can be coated with polytetrafluoroethylene to prevent the expansion and contraction that may be caused by the adhesion of high-ductility concrete.

[0027] like Figure 5 , Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the pushing assembly further includes a side plate 8, a second lead screw 801, a second sleeve 802, an elastic telescopic plate 803, and a pusher seat 9. The pusher seat 9 is slidably connected to the main scraper 2 and moves against the auxiliary scraper 5. A secondary bevel gear 8011 is provided on the second lead screw 801, and a main bevel gear 4021 that meshes with the secondary bevel gear 8011 is provided on the first lead screw 402. In actual use, a sealing cover can be provided at the bevel gear meshing point as needed to prevent mud splashing and adhesion from affecting its transmission. Furthermore, the auxiliary scraper 5 includes a first plate body 501 and a second plate body 502. A second torsion spring for driving the second plate body 502 to reset and rotate is provided on the second pin. The pusher seat 9 includes a first pusher seat 901 and a second pusher seat 902. The second pusher seat 902 is movably abutted against the second plate body 502. Furthermore, a connecting plate 10 is fixedly mounted on the outer side of the fixed base 301 via a connecting plate, and a protrusion 1001 is provided on the connecting plate 10 that movably abuts against the end of the second plate 502. When the angle adjustment frame 4 is working, the main bevel gear 4021 on the first lead screw 402 meshes with the secondary bevel gear 8011 on the second lead screw 801. The second sleeve 802 drives the pusher seat 9 to move through the elastic telescopic plate 803, so that the pusher seat 9 pushes the auxiliary scraper 5. The auxiliary scraper 5 changes from being perpendicular to the main scraper 2 to being horizontal to the main scraper 2, increasing the downward scraping width of the main scraper 2, so that the auxiliary scraper 5 scrapes the vertical connecting protrusion at the edge of the main scraper 2. During this period, the second pusher seat 902 of the pusher seat 9 limits the first plate 501 and the second plate 502 to prevent the first plate 501 and the second plate 502 from deflecting, ensuring the flatness of the main scraper 2 and the auxiliary scraper 5 when scraping downward, and preventing the auxiliary scraper 5 from loosening or tilting and affecting the scraping effect on the high ductility concrete. After the wall and floor meet, the first screw 402 rotates in the opposite direction to readjust the tilt of the main scraper 2, so that the main scraper 2 can apply high-ductility concrete to the top of the wall. When the first screw 402 rotates, the second sleeve 802 moves back, so that the pusher seat 9 no longer applies a pushing force to the auxiliary scraper 5. The auxiliary scraper 5 resets and rotates under the action of the torsion spring. Then the first motor 405 stops running. When the angle adjustment frame 4 drives the main scraper 2 to move upward with the slide 308, the tilted downward second plate 502 intermittently abuts against the protrusion 1001, causing the second plate 502 to vibrate relative to the main scraper 2, shaking off the high-ductility concrete adhering to the second plate 502. This ensures that the subsequent auxiliary scraper 5 effectively scrapes the concrete protrusions in the edge area of ​​the main scraper 2, improving the smoothness of the surface. No further repairs are needed, reducing the waste of human resources.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment proposes a wall plastering reinforcement device using high-ductility concrete, including the plastering component mentioned above, and also includes a guide rail 11, a movable base 1 slidably connected to the guide rail 11, a slurry storage tank 12 provided on the movable base 1, a material guide pipe 121 connected to the slurry storage tank 12, an mounting plate 13 fixedly provided on the first sleeve 403, a pump body 131 provided on the mounting plate 13, the inlet end of the pump body 131 connected to the material guide pipe 121, the outlet end of the pump body 131 connected to a mud spray nozzle 132 rotatably connected to the mounting plate 13, a second motor 14 fixedly provided on the mounting plate 13, the output shaft of the second motor 14 connected to a drive gear 141, and a driven gear 142 meshing with the drive gear 141 provided on the mud spray nozzle 132; During wall plastering and reinforcement, the pump 131 is controlled to operate. The pump 131 sprays the high-ductility concrete in the slurry storage tank 12 onto the wall to be plastered and reinforced through the slurry nozzle 132. During this period, the second motor 14 is controlled to operate, so that the output shaft of the second motor 14 drives the drive gear 141 to mesh with the driven gear 142, so that the driven gear 142 drives the slurry nozzle 132 to swing back and forth, thereby making the slurry nozzle 132 evenly spray the slurry onto the wall to be reinforced and plastered. After use, the slurry nozzle 132 should be cleaned with clean water to prevent the slurry from hardening and clogging the nozzle during subsequent use. It should be noted that a protective shell should be added to the gear meshing point to prevent concrete from scattering at the gear and affecting the gear transmission. After one vertical surface of the wall is plastered, the moving base 1 slides on the guide rail 11, thereby making the moving base 1 move smoothly.

[0029] This embodiment also discloses a method for reinforcing walls using high-ductility concrete plastering. The method involves applying the aforementioned wall reinforcement equipment using high-ductility concrete plastering, and includes the following steps: S1: Place the reinforcement equipment in front of the wall to be reinforced, place the guide rail 11 under the moving base 1, and control the lifting rod 303 to push the moving base 302 upward until the top plate 304 abuts against the floor above the wall. At this time, fix the position of the processing equipment. The main scraper 2 is placed at an angle and the end closest to the wall is the high end. S2: Then control the winch 306 and pump 131 to work. The pump 131 sprays the high ductility concrete in the slurry tank 12 onto the wall to be plastered and reinforced through the mud nozzle 132. As the winch 306 drives the slide 308 to move upward through the winding rope 307, the angle adjustment frame 4 drives the main scraper 2 to move upward with the slide 308. During this period, the main scraper 2 performs preliminary plastering of the high ductility concrete sprayed on the wall. S3: When the main scraper 2 is about to move to the top of the wall, control the pump body 131 to stop working. After the end of the main scraper 2 near the wall moves to the top of the wall, control the first motor 405 to run, so that the first lead screw 402 rotates on the U-shaped plate 401. The first sleeve 403 moves upward along the axis of the first lead screw 402. The first sleeve 403 drives the swing member 404 to rotate around the second pin as the center, changing the tilt angle of the main scraper 2, so that the end of the main scraper 2 near the wall is the bottom end. S4: When the first lead screw 402 rotates, the main bevel gear 4021 meshes with the secondary bevel gear 8011 on the second lead screw 801, and the second sleeve 802 drives the pusher seat 9 to move through the elastic telescopic plate 803, so that the pusher seat 9 pushes the auxiliary scraper 5. The auxiliary scraper 5 changes from being perpendicular to the main scraper 2 to being placed horizontally with the main scraper 2, increasing the downward scraping width of the main scraper 2. During this period, the second pusher seat 902 of the pusher seat 9 limits the first plate 501 and the second plate 502 to prevent the first plate 501 and the second plate 502 from deflecting. Then, the first motor 405 is controlled to stop running. S5: Then the winch 306 releases the winding rope 307, and the slide block 308 slides vertically down under its own weight. The main scraper 2, together with the auxiliary scrapers 5 on both sides, scrapes the high ductility concrete after smearing, making the surface of the high ductility concrete smooth, until the main scraper 2 and the auxiliary scrapers 5 scrape down to the position where the wall and the floor meet. S6: Then control the first motor 405 to drive the first lead screw 402 to rotate in the opposite direction, so that the first sleeve 403 moves down along the first lead screw 402, readjusting the tilt state of the main scraper 2 so that the main scraper 2 can apply the high ductility concrete to the top of the wall. When the first lead screw 402 rotates, the second sleeve 802 moves back, so that the pusher seat 9 no longer applies a pushing force to the auxiliary scraper 5. The auxiliary scraper 5 resets and rotates under the action of the torsion spring, and then the first motor 405 stops running. S7: Then slide the movable base 1 on the guide rail 11 to adjust the wall plastering reinforcement area. Repeat step S2. When the angle adjustment frame 4 drives the main scraper 2 to move upward with the slide 308, the inclined downward second plate 502 intermittently abuts against the protrusion 1001, causing the second plate 502 to shake relative to the main scraper 2, causing the high ductility concrete adhering to the second plate 502 to fall off. Repeat steps S3-S6 to achieve plastering reinforcement of another area of ​​the wall.

10. A method for reinforcing walls using high-ductility concrete plastering, comprising reinforcing walls using high-ductility concrete plastering equipment as described in claim 9, characterized in that, Includes the following steps: S1: Place the reinforcement equipment in front of the wall to be reinforced, place the guide rail (11) under the moving base (1), and control the lifting rod (303) to push the moving base (302) up until the top plate (304) abuts against the floor above the wall. Fix the position of the processing equipment at this time. The main scraper (2) is placed at an angle and its end near the wall is the high end. S2: Then control the winch (306) and pump (131) to work. The pump (131) sprays the high ductility concrete in the slurry tank (12) onto the wall to be plastered and reinforced through the mud nozzle (132). As the winch (306) drives the slide (308) to move upward through the winding rope (307), the angle adjustment frame (4) drives the main scraper (2) to move upward with the slide (308). During this period, the main scraper (2) performs preliminary plastering of the high ductility concrete sprayed on the wall. S3: When the main scraper (2) is about to move to the top of the wall, control the pump body (131) to stop working. After the main scraper (2) moves to the top of the wall at the end close to the wall, control the first motor (405) to run, so that the first screw (402) rotates on the U-shaped plate (401), and the first sleeve (403) moves upward along the first screw (402) axis. The first sleeve (403) drives the swinging part (404) to rotate around the second pin shaft, changing the tilt angle of the main scraper (2) so that the end of the main scraper (2) close to the wall is the bottom end. S4: When the first lead screw (402) rotates, the main bevel gear (4021) meshes with the secondary bevel gear (8011) on the second lead screw (801). The second sleeve (802) drives the pusher seat (9) to move through the elastic telescopic plate (803), so that the pusher seat (9) pushes the auxiliary scraper (5). The auxiliary scraper (5) changes from being perpendicular to the main scraper (2) to being horizontally placed with the main scraper (2), increasing the downward scraping width of the main scraper (2). During this period, the second pusher seat (902) of the pusher seat (9) limits the first plate (501) and the second plate (502) to prevent the first plate (501) and the second plate (502) from deflecting. Then, the first motor (405) is controlled to stop running. S5: Then the winch (306) releases the winding rope (307), and the slide (308) slides down vertically under its own weight. The main scraper (2) and the auxiliary scrapers (5) on both sides scrape down the high ductility concrete after troweling, so that the surface of the high ductility concrete is smooth, until the main scraper (2) and the auxiliary scrapers (5) scrape down to the position where the wall and the floor meet. S6: Then control the first motor (405) to drive the first screw (402) to rotate in the opposite direction, so that the first sleeve (403) moves down along the first screw (402) and readjusts the tilt state of the main scraper (2) so that the main scraper (2) can apply high ductility concrete to the top of the wall. When the first screw (402) rotates, the second sleeve (802) moves back, so that the pusher seat (9) no longer applies a pushing force to the auxiliary scraper (5). The auxiliary scraper (5) resets and rotates under the action of the torsion spring, and then the first motor (405) stops running. S7: Then slide the movable base (1) on the guide rail (11), adjust the wall plastering reinforcement area, repeat step S2, when the angle adjustment frame (4) drives the main scraper (2) to move up with the slide (308), the inclined downward second plate (502) intermittently abuts against the protrusion (1001), so that the second plate (502) shakes relative to the main scraper (2), so that the high ductility concrete adhering to the second plate (502) is shaken off. Repeat steps S3-S6 to achieve plastering reinforcement of another area of ​​the wall.
