Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a wall roughening construction device and construction method. Background Technology

[0002] In architectural decoration projects, the preparation of the substrate before plastering is a crucial step affecting the quality of the plastering. Roughening the surface enhances the mechanical bond and adhesion between the plaster layer and the substrate by creating a rough interface, effectively preventing common quality defects such as hollow spots and cracking.

[0003] There are two main types of existing roughening techniques: one is to spray mortar onto the wall surface using a spray gun. This method has problems such as insufficient roughness, serious mortar rebound waste, and large dust pollution. In addition, the direction of the burrs formed by the spray is random, which has limited anchoring effect on the plaster layer. The other is to use manual patting method, in which workers hold a patting board and pat the mortar onto the wall surface. This method is extremely labor-intensive, has low construction efficiency, and the uniformity of roughening is highly dependent on the worker's operating experience, making it difficult to guarantee quality stability.

[0004] Furthermore, existing mechanized surface roughening equipment mostly uses a rigid pressing method, which cannot adapt to deviations in wall flatness. It also lacks intelligent recognition capabilities when encountering door and window openings, leading to continuous mortar pumping, resulting in pollution and waste. Therefore, there is an urgent need for a device and method that can uniformly, efficiently, and adaptively roughen walls. Summary of the Invention

[0005] In order to improve the problems of uneven roughening, high labor intensity, serious mortar waste and inability to adapt to wall conditions in the existing technology, this application provides a wall roughening construction device and construction method.

[0006] Firstly, this application provides a wall roughening construction device, which adopts the following technical solution: A wall roughening construction device includes a movable base, a lifting mechanism disposed on the movable base, and a mortar pumping system, and further includes: A telescopic mechanism is installed at the lifting end of the lifting mechanism and has a telescopic part that can extend or retract toward the wall to be constructed. A texturing mechanism includes a texturing roller installed on the telescopic part. The texturing roller includes a perforated cylinder wall, a shaft, and a first scraper, a second scraper, and a third scraper installed on the shaft. The first scraper and the second scraper form a first included angle, and the second scraper and the third scraper form a second included angle. The first scraper and the second scraper are provided with fan-shaped sealing plates at both ends to form a semi-closed triangular chamber with the perforated cylinder wall. The triangular chamber is connected to the mortar pumping system. An elastic bonding mechanism includes a spring sleeve disposed between a telescopic portion and a napping roller, and a pressure detection element configured to detect the elastic compression and generate a trigger signal; and The control system is configured to receive the trigger signal and control the start and stop of the mortar pumping system.

[0007] Furthermore, the triangular chamber has an opening facing the perforated cylinder wall, the perforated cylinder wall area between the first scraper and the second scraper constitutes the working area, and the perforated cylinder wall area between the second scraper and the third scraper constitutes the recycling area.

[0008] Furthermore, the first included angle is 25° to 45°, the second included angle is 140° to 160°, and the bisector of the included angle between the first scraper and the second scraper is configured to be consistent with the horizontal direction.

[0009] Furthermore, a high-precision pressure sensor is provided in the triangular chamber, and the control system is configured to adjust the pumping pressure of the mortar pumping system according to the feedback signal of the high-precision pressure sensor, so as to maintain the pressure in the triangular chamber within the range of 0.15MPa to 0.35MPa.

[0010] Furthermore, two sets of spring sleeves are provided between the telescopic part and the brushing roller. Each set of spring sleeves includes a sleeve body, a support rod and a compression spring. One end of the support rod passes through the sleeve body and abuts against the compression spring, and the other end is connected to the shaft end of the brushing roller. The pressure detection element is a limit switch or pressure sensor installed in the sleeve body. The trigger signal is generated when the compression spring is compressed by 8mm to 12mm.

[0011] Furthermore, it also includes a waste material recycling mechanism, which includes a bidirectional scraper disposed below the textured roller and a mortar collection tank suspended directly below the bidirectional scraper; The bidirectional scraper is configured to scrape off the mortar adhering to the outer surface of the perforated cylinder wall when the textured roller moves up or down, and the third scraper in the recycling zone is configured to scrape off the residual mortar retained in the holes of the perforated cylinder wall and guide it to the temporary storage area between the second scraper and the third scraper.

[0012] Furthermore, the base is equipped with multiple distance measurement modules, and the control system is configured as follows: Receive the input drawing information of the space to be constructed and the planned route; The real-time position of the base in space is calculated based on the measurement data from the distance measurement module; The mobile base is controlled to travel along the planned route, and when it reaches the preset working position, the telescopic part is controlled to extend so that the textured roller fits against the wall.

[0013] Furthermore, the control system is also configured to: After the textured roller completes one stroke along the wall surface, the telescopic part is controlled to retract, causing the textured roller to detach from the wall surface. Control the movable base to travel along the length of the wall by a unit distance equal to the length of the textured roller; The telescopic part is controlled to extend again, causing the textured roller to fit against the wall and compressing the spring sleeve to enter the next stroke.

[0014] Secondly, this application provides a wall roughening construction method based on the aforementioned wall roughening construction device, comprising the following steps: S1. Move the movable base to the starting position of the wall surface to be constructed, so that the outer surface of the textured roller maintains a first distance from the wall surface; S2. Control the telescopic part to extend horizontally, so that the outer surface of the textured roller is in contact with the wall and the spring sleeve is compressed to a preset compression amount, and the pressure detection element generates a trigger signal; S3. The control system receives the trigger signal and starts the mortar pumping system to pump the mortar into the triangular cavity; S4. Control the lifting mechanism to drive the telescopic part to rise or fall vertically, the textured roller rolls around the shaft, and the mortar in the triangular cavity is squeezed out from the holes in the working area under pressure and adheres to the wall surface to form textured points; S5. When the telescopic part reaches the end of its stroke, the control system controls the mortar pumping system to stop pumping and controls the telescopic part to retract so that the textured roller is removed from the wall surface; S6. Control the moving base to travel one unit distance along the length of the wall, and repeat steps S2 to S5 until the wall roughening operation is completed.

[0015] Furthermore, in step S4, when the textured roller travels to the door and window opening area, the compression of the spring sleeve decreases to below a preset threshold, the pressure detection element generates a stop signal, and the control system receives the stop signal and controls the mortar pumping system to stop pumping. When the textured roller leaves the door and window opening area and re-adheres to the wall, the compression of the spring sleeve returns to the preset compression, and the mortar pumping system resumes pumping.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. The triangular chamber structure formed by three scrapers limits the mortar extrusion area to the working area between the first and second scrapers. Combined with the pressure control of a high-precision screw pump, the mortar is uniformly extruded from the holes and forms roughened points with directional spikes under the action of cohesion. The roughening density and height uniformity are significantly improved, and the pull-out strength is significantly improved compared with manual slurry application. 2. The mortar extruded from the working area is immediately applied during the rolling of the textured roller, and the holes in the non-working area are sealed by the third scraper to prevent the mortar from overflowing in a disorderly manner; the elastic bonding mechanism ensures that the mortar pumping system only starts pumping when the textured roller is effectively in contact with the wall surface, and automatically stops pumping when it encounters door and window openings, fundamentally eliminating mortar dripping pollution caused by ineffective pumping. 3. The third scraper removes the residual mortar trapped in the holes and guides it to the temporary storage area. Combined with the bidirectional scraper on the outer wall for real-time cleaning, it realizes a closed-loop cycle of "extrusion-coating-recycling", avoids hole blockage, ensures continuous operation capability, and can significantly extend the equipment maintenance cycle. 4. By integrating drawing recognition, path planning, automatic positioning and linkage control functions into the control system, semi-automatic construction can be achieved. Only one auxiliary worker is needed to operate a single piece of equipment, which can greatly improve the daily construction area and construction quality. Attached Figure Description

[0023] The text appears to be a fragmented collection of characters and phrases, possibly from different sources. A direct translation isn't possible without further context or clarification. Figure 3and Figure 4 The system includes a textured roller 12 installed on the telescopic part 9. The textured roller 12 includes a perforated cylinder wall 12-1, a shaft 12-6, and a first scraper 12-3, a second scraper 12-4, and a third scraper 12-5 installed on the shaft 12-6. The first scraper 12-3 and the second scraper 12-4 form a first included angle, and the second scraper 12-4 and the third scraper 12-5 form a second included angle. The two ends of the first scraper 12-3 and the second scraper 12-4 are provided with fan-shaped sealing plates to form a semi-closed triangular chamber with the perforated cylinder wall 12-1. The triangular chamber is connected to the mortar pumping system. Specifically, waterproof bearings 12-2 are installed at both ends of the shaft 12-6, and the two ends of the perforated cylinder wall 12-1 are respectively installed on the two waterproof bearings 12-2. The thickness of the perforated cylinder wall is preferably 5mm, and small holes with an area of ​​about 0.8 square centimeters are evenly distributed on its cylinder wall. After the perforated cylinder is fitted onto the two waterproof bearings 12-2, one edge of each of the three scrapers is in close contact with the inner wall of the perforated cylinder.

[0025] Specifically, refer to Figure 3 and Figure 4 The triangular chamber has an opening facing the perforated cylindrical wall 12-1. The area of ​​the perforated cylindrical wall 12-1 between the first scraper 12-3 and the second scraper 12-4 constitutes the working area, and the area of ​​the perforated cylindrical wall 12-1 between the second scraper 12-4 and the third scraper 12-5 constitutes the recovery area.

A high-precision pressure sensor is installed inside the triangular chamber, and the control system is configured to adjust the pumping pressure of the mortar pumping system based on the feedback signal from the high-precision pressure sensor to maintain the pressure inside the triangular chamber within the range of 0.15 MPa to 0.35 MPa.

[0026] Furthermore, two sets of spring sleeves 10 are provided between the telescopic part 9 and the brushing roller 12. Each set of spring sleeves 10 includes a sleeve body, a support rod 11 and a compression spring. One end of the support rod 11 passes through the sleeve body and abuts against the compression spring, and the other end is connected to the end of the shaft 12-6 of the brushing roller 12. The pressure detection element is a limit switch or pressure sensor installed in the sleeve body. The trigger signal is generated when the compression spring is compressed by 8mm to 12mm.

[0027] In addition, refer to Figure 1 and Figure 2 The wall surface roughening construction device of this application also includes a waste material recycling mechanism, which includes a bidirectional scraper 13 located below the roughening roller 12 and a mortar collection tank 14 suspended directly below the bidirectional scraper 13. The bidirectional scraper 13 is configured to scrape off the mortar adhering to the outer surface of the perforated cylinder wall 12-1 when the textured roller 12 moves up or down, and the third scraper 12-5 in the recovery zone is configured to scrape off the residual mortar retained in the holes of the perforated cylinder wall 12-1 and guide it to the temporary storage area between the second scraper 12-4 and the third scraper 12-5.

[0028] In addition, the mobile base 1 is equipped with multiple distance measurement modules 4, and the control system is configured as follows: Receive the input drawing information of the space to be constructed and the planned route; The real-time position of the base in space is calculated based on the measurement data from the distance measurement module 4; Control the mobile base 1 to travel along the planned route, and when it reaches the preset working position, control the telescopic part 9 to extend so that the textured roller 12 fits against the wall surface 19.

[0029] Furthermore, the control system is configured as follows: After the textured roller 12 completes one stroke along the wall surface 19, the telescopic part 9 is controlled to retract so that the textured roller 12 is removed from the wall surface 19. Control the movable base 1 to travel a unit distance equal to the length of the textured roller 12 along the length direction of the wall 19; The telescopic control section 9 extends again to make the textured roller 12 fit against the wall surface 19 and compress the spring sleeve 10 to enter the next stroke.

[0030] Therefore, referring to Figure 5 and Figure 6When using the wall roughening construction device of this application for wall roughening construction, taking the application of the wall roughening construction device in the plastering construction of a residential building as an example, firstly, the wall roughening construction device is transported to the apartment that needs roughening. The mobile base 1 is placed at the starting point of the planned travel route, about 300mm away from the wall, and an appropriate amount of mortar is injected into the mortar tank 16 on the mobile base 1. The power is turned on, and the three-dimensional or two-dimensional drawing information of the apartment that needs roughening is input into the control system. Then, the planned travel route is input, and a specific room of the wall roughening construction device in the apartment is marked. After marking the specific room, the control system is run. The control system starts the distance measurement module 4, analyzes the measurement results of multiple distance measurement modules 4, and calculates the specific position of the wall roughening construction device in the apartment by combining it with the input drawing information. The control system controls the mobile base 1 to perform roughening construction along the planned travel route. During the roughening process, the control system records the route of the completed roughening work and performs self-positioning and confirms the planned route every 5 minutes.

[0031] Specifically, after the control system is activated, the wall surface roughening device completes its self-positioning and equipment reset. The rapid lifting hydraulic rod 5 retracts to its shortest position, and the lifting platform 7 descends to its lowest point. Then, the control system controls the wall surface roughening device to move until the distance between the front distance measuring module 4 and the wall surface is 19300mm, that is, the outer surface of the roughening roller 12 is 1930mm away from the wall surface. At this point, the wall surface roughening device stops moving and controls the direction of the four universal wheels 2 on the moving base 1 to be parallel to the wall surface 19. Then, the control system controls the telescopic part 9 to extend forward by 40mm, so that the outer surface of the roughening roller 12 is in close contact with the wall surface 19 and the spring 10 in the spring sleeve 10 is compressed by 10mm. When the control system receives the trigger signal from the pressure detection element, the control system starts the mortar pump 17, which pumps the mortar in the mortar tank 16 into the triangular cavity inside the roughening roller 12 through the conveying pipe 15. When the pressure inside the triangular cavity reaches the preset value, specifically detected by a high-precision pressure sensor, the control system controls the lifting platform 7 to move upward along the rack 6. The textured roller 12 rolls on the wall surface 19 around the shaft 12-6. The shaft 12-6 does not rotate, nor do the three scrapers. Only the perforated cylinder wall 12-1 rotates around the axis connecting the waterproof bearing 12-2, i.e., around the shaft 12-6. Under the pressure, the mortar inside the triangular cavity flows into the small hole of the perforated cylinder wall 12-1 of the textured roller 12. The mortar in the small hole contacts and adheres to the wall surface 19. When the textured roller 12 rolls past the wall surface 19, the mortar in the small hole separates from the mortar inside the triangular cavity. Due to the cohesive force of the mortar, the mortar points adhering to the wall surface 19 are pulled into mortar points with sharp points, leaving rows of mortar points on the wall surface 19, thus achieving the textured effect of the wall surface 19.

[0032] Since the mortar pump 17 pumps mortar into the semi-enclosed space formed by the first scraper 12-3, the second scraper 12-4, the sealing plates at both ends, and part of the perforated cylinder wall 12-1, the mortar will only overflow from the reserved holes of the perforated cylinder wall 12-1 of the textured roller 12 between the first scraper 12-3 and the second scraper 12-4 after being squeezed, and will not overflow from other reserved holes of the textured roller 12. This reduces the waste of mortar.

[0033] Furthermore, the mortar adhering to the inner wall of the texturing roller 12 is scraped off by the first scraper 12-3 and the second scraper 12-4 and remains in the triangular cavity when the texturing roller 12 rolls. The mortar adhering to the outer wall of the texturing roller 12 is scraped off by the bidirectional scraper 13 on the outer wall when the texturing roller 12 rolls upward or downward and drips into the mortar collection tank 14. The mortar adhering to the thickness of the wall of the textured roller 12, i.e., the reserved hole, will drip out from the inside of the wall of the textured roller 12 and be scraped off by the third scraper 12-5, and then drip onto the platform formed by the third scraper 12-5 and the second scraper 12-4, which can be cleaned manually; some mortar will drip out from the outside of the wall of the textured roller 12 and be scraped off by the bidirectional scraper 13 on the outer wall, and then drip into the collection tank; some mortar will remain in the reserved hole. When the reserved hole is rotated to the area between the first scraper 12-3 and the second scraper 12-4, the new mortar mixed with the mortar remaining in the reserved hole will be squeezed onto the wall surface 19 and adhere to the wall surface 19, forming textured mortar points.

[0034] When the lifting platform 7 rises to the top of the rack 6, the lifting platform 7 locks with the rack 6, and the rapid lifting hydraulic rod 5 is activated. The rapid lifting hydraulic rod 5 continues to lift the lifting platform 7 until the textured roller 12 on the lifting platform 7 moves to the preset highest point of textured surface. The textured roller 12 leaves mortar dots on the wall surface 19 it passes through, achieving the textured effect. After the textured roller 12 reaches the highest point, the control system controls the mortar pump 17 to stop pumping mortar, and the telescopic part 9 retracts, causing the textured roller 12 to detach from the wall surface 19. Then, the control system controls the wall textured construction device to move one unit length along the length of the wall surface 19, which is the length of the textured roller 12. Then, the control system controls the telescopic part 9 to extend forward by 40mm. After the textured roller 12 encounters the wall, the spring is compressed by 10mm, so that the outer surface of the textured roller 12 is tightly attached to the wall surface 19.

[0035] Then, the control system starts the mortar pump 17, and the rapid lifting hydraulic rod 5 retracts and descends, simultaneously driving the textured roller 12 on the lifting platform 7 downwards. When the rapid lifting hydraulic rod 5 retracts to the lowest point, the lifting platform 7 is unlocked from the rack 6, and the lifting platform 7 continues to descend along the rack 6 until the lowest point, at which point the mortar pump 17 stops, and the textured roller 12 leaves mortar spots in the area it has passed through. Subsequently, the control system controls the lifting platform 7 to retract, causing the textured roller 12 to detach from the wall surface 19; the control system then controls the wall textured construction device to continue moving one unit length along the length of the wall surface 19, entering the next cycle.

[0036] Therefore, the control system controls the moving base 1 to move along the planned route, which can complete the roughening of the wall surface 19. When the length of the wall surface 19 is not an integer multiple of the length of the roller, the width of the last roughening layer overlaps with the width of the second to last roughening layer. When encountering door or window openings during the roughening process, the mutual thrust between the roughening roller 12 and the wall surface 19 will disappear, the spring in the spring sleeve 10 will rebound, and at the same time, the control circuit of the mortar pump 17 will be disconnected, causing the mortar pump 17 to stop working, and the lifting platform 7 will continue to rise or fall. When the roughening roller 12 contacts the wall surface 19 again during the upward or downward movement, the roughening roller 12 is squeezed by the wall surface 19 and compresses the spring in the sleeve again, while at the same time, the control circuit of the mortar pump 17 is connected, and the mortar pump 17 continues to work, providing sufficient roughening mortar to the roughening roller 12.

[0037] This application also discloses a wall roughening construction method, based on the above-mentioned wall roughening construction device, and adopts the following technical solution: A method for roughening wall surfaces, referring to Figure 1 - Figure 6 This includes the following steps: S1. Move the movable base 1 to the starting position of the wall surface 19 to be constructed, so that the outer surface of the textured roller 12 maintains a first distance from the wall surface 19; S2. Control the telescopic part 9 to extend horizontally, so that the outer surface of the textured roller 12 is in contact with the wall surface 19 and the spring sleeve 10 is compressed to the preset compression amount, and the pressure detection element generates a trigger signal; S3. The control system receives the trigger signal and starts the mortar pumping system, sending the mortar pump 17 into the triangular chamber; S4. Control the lifting mechanism to drive the telescopic part 9 to rise or fall vertically, the textured roller 12 rolls around the shaft 12-6, and the mortar in the triangular cavity is squeezed out from the holes in the working area under pressure and adheres to the wall surface 19 to form textured points. S5. When the telescopic part 9 reaches the end of its stroke, the control system controls the mortar pumping system to stop pumping and controls the telescopic part 9 to retract so that the textured roller 12 is separated from the wall surface 19. S6. Control the moving base 1 to move one unit distance along the length of the wall 19, and repeat steps S2 to S5 until the roughening operation of the wall 19 is completed.

[0038] In step S4, when the textured roller 12 moves to the door and window opening area, the compression of the spring sleeve 10 decreases to below the preset threshold, the pressure detection element generates a stop signal, the control system receives the stop signal and controls the mortar pumping system to stop pumping. When the textured roller 12 leaves the door and window opening area and re-fits the wall surface 19, the compression of the spring sleeve 10 returns to the preset compression, and the mortar pumping system resumes pumping.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
