Description

Technical Field

[0001] This application relates to the field of crack repair, and in particular to a device for repairing cracks in building walls. Background Technology

[0002] Building wall cracks are cracks that occur in the wall part of a building structure. Depending on the type of crack, they can usually be divided into wall cracks and wall surface cracks. In current housing, in addition to wall cracks that are prone to occur due to building quality problems, wall surface cracks are more common.

[0003] Most interior wall cracks are caused by temperature differences in the putty layer, which leads to cracking on the wall surface. While this does not significantly affect the building's safety, it does impact the aesthetics of the interior. Therefore, these cracks are often repaired. In current technology, putty is usually reapplied to the cracks to repair them. The tools used for applying putty are mostly rollers, which are used to apply putty to the cracks after it has been applied, thus covering them up.

[0004] However, while using rollers alone can treat cracks on the surface of walls and ceilings, it is not ideal for cracks at the junction of the wall and ceiling. Due to the shape of the rollers, they cannot fit perfectly at the junction. Often, workers need to be at a height and use other tools to repair the cracks at the junction of the wall and ceiling. In this process, workers not only need to change tools, but also need to climb up and down stairs to repair the cracks at the junction of the wall and ceiling. This makes repairing cracks at the junction of the ceiling and the wall time-consuming and inefficient. Summary of the Invention

[0005] In order to improve the efficiency of repairing cracks at the junction of ceiling and wall, this application provides a device for repairing cracks in building walls.

[0006] The technical solution for a building wall crack repair device provided in this application is as follows:

[0007] The device includes a telescopic movable frame, a crack repair assembly, and a putty holding assembly. The telescopic movable frame includes a base, a fixed frame, and a movable frame. The fixed frame is slidably mounted on the base, and the movable frame is slidably mounted on the fixed frame. The putty holding assembly is installed on the fixed frame and is used to hold putty for repairing cracks. The crack repair assembly includes a rotating frame, a repair roller, and a repair block. The rotating frame is installed on the movable frame and can rotate. The repair roller and the repair block are both installed on the rotating frame and can alternately appear above the putty holding assembly as the rotating frame rotates. The repair roller is used to repair cracks on the wall surface, and the repair block is used to repair cracks at the junction of the wall and the ceiling.

[0008] By adopting the above technical solution, when cracks form in the putty on the upper surface of the wall, the base is moved to the wall, and then the fixing frame is pushed, causing the fixing frame to slide on the base towards the wall surface. This allows the paste-holding component and crack repair component on the fixing frame to move closer to the wall surface. The repair roller and repair block can be lowered from top to bottom by the movable frame on the fixing frame and enter the paste-holding component to be filled with the putty to be applied to the wall surface. Subsequently, the movable frame extends on the fixing frame, allowing the repair roller to come into contact with the crack on the ceiling and apply the repair roller to the crack through the reciprocating motion of the fixing frame on the base. When it is necessary to repair cracks at the vertical connection between the ceiling and the wall, the repair block is rotated by the rotating frame to come into contact with the vertical connection between the ceiling and the wall, and then the crack at that location is repaired by the repair block. The entire process does not require manual tool replacement, nor does it require workers to climb up and down, thus improving the efficiency of repairing cracks at the connection between the ceiling and the wall.

[0009] Optionally, the rotating frame includes a rotating shaft, mounting rod one, mounting rod two, and two connecting plates. The rotating shaft is mounted on the movable frame and can rotate around its own axis. The two connecting plates are respectively mounted at both ends of the rotating shaft and can rotate with the rotating shaft. Mounting rod one and mounting rod two are both located between the two connecting plates and are parallel to the rotating shaft. They are located at both ends of the connecting plates and connected to the connecting plates. The repair roller is mounted on mounting rod one and can rotate around its own axis. The repair block is mounted on mounting rod two and can slide back and forth along the axis of mounting rod two.

[0010] By adopting the above technical solution, when it is necessary to repair cracks on the ceiling surface, the repair roller can be used for repair. The repair roller can rotate around its own axis on the first mounting rod, so that the repair roller can roll along the extension direction of the crack on the ceiling surface, thereby following the crack for repair. The repair block can reciprocate along the axis of the second mounting rod, so that when repairing cracks at the vertical connection between the wall and the ceiling, the repair block can sand and smooth the applied putty by reciprocating along the axis of the second mounting rod.

[0011] Optionally, the movable frame is provided with a drive assembly, which is used to drive the rotating shaft to rotate around its own axis on the movable frame.

[0012] By adopting the above technical solution, the rotating shaft can rotate around its own axis on the movable frame through the drive component, thereby enabling the repair roller and repair block to be used alternately to suit different environments.

[0013] Optionally, the drive assembly includes a drive actuator, a drive wheel, and a driven wheel. The drive actuator is mounted on the movable frame and connected to the drive wheel. The drive wheel is mounted on the end of the rotating shaft. When the drive wheel rotates, the driven wheel rotates along with it.

[0014] By adopting the above technical solution, when the drive actuator is started, the drive wheel also rotates, which in turn drives the driven wheel to rotate together, thereby driving the connecting shaft to rotate around its own axis on the movable frame. At the same time, the rotation angle of the drive actuator can also be controlled to adjust the rotation angle of the connecting shaft, thereby allowing the extension height of the repair roller or repair block on the movable frame to be adjusted.

[0015] Optionally, one of the connecting plates is provided with a pusher, which is used to push the repair block to slide on the mounting rod. The pusher is located between the mounting rod and the rotating shaft.

[0016] By adopting the above technical solution, after starting, the pusher can push the repair block to slide back and forth on the mounting rod 2 along the axis of the mounting rod 2. The pusher is located between the mounting rod 2 and the rotating shaft so that when the repair block enters the slurry-holding assembly with the rise and fall of the movable part, the pusher will not easily adhere to the putty in the slurry-holding assembly.

[0017] Optionally, a second pusher is provided on the base, which is used to push the fixed frame to reciprocate on the base.

[0018] By adopting the above technical solution, by setting a second pusher on the base, the second pusher can push the fixed frame to reciprocate on the base, so that the fixed frame can move towards the wall on the base, so that the repair roller can repair along the extension direction of the crack, and also so that the repair block can abut and repair the crack at the vertical connection between the ceiling and the wall.

[0019] Optionally, the pulp holding assembly includes a pulp holding box and a lifting component. The lifting component is mounted on a fixed frame and connected to the pulp holding box. Both the fixed frame and the movable frame are provided with sliding grooves. The pulp holding box is provided with a sliding part that matches the sliding groove. The sliding part is located inside the sliding groove, and the pulp holding box can slide inside the sliding groove under the push of the lifting component.

[0020] By adopting the above technical solution, the putty box can slide along the length of the fixed frame and the movable frame under the action of the lifting component. This allows the putty box to be lifted after being filled with putty, thereby shortening the distance between it and the repair roller and the repair block. This makes it highly likely that when excess putty adhered to the repair roller and the repair block falls, it will fall back into the putty box, reducing the possibility of putty dripping onto the ground during the repair process.

[0021] Optionally, scraper blades are provided on both opposite sides of the slurry box. The scraper blades are used to scrape off excess putty from the repair roller or repair block.

[0022] By adopting the above technical solution, when the repair block and repair roller have a lot of putty adhering to them in the slurry box, the scraper will scrape off the excess putty, so that when the repair roller and repair block are repairing, there will not be too much putty adhering to the area to be repaired, and the repair roller and repair block can level the area to be repaired in a shorter time.

[0023] In summary, this application includes at least the following beneficial technical effects:

[0024] 1. By setting a rotating shaft, the positions of the repair block and the repair roller can be alternated. This allows for the selection of repair blocks and rollers based on the actual situation when repairing cracks on the ceiling surface or cracks between the ceiling and the wall. This eliminates the need for workers to spend time searching for replacement tools when repairing cracks at the connection between the ceiling and the wall. Furthermore, the extension and retraction of the movable frame on the fixed frame allows workers to repair cracks without climbing up and down, thus saving time and improving the efficiency of repairing cracks at the connection between the ceiling and the wall.

[0025] 2. By setting a pusher that can push the repair block to reciprocate along the axis of the mounting rod, it is possible to repair the crack between the ceiling and the wall even if the direction of extension is consistent with the direction of extension of the edge of the connection between the ceiling and the wall, thereby increasing the applicability of the repair block.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a device for repairing cracks in building walls, referring to... Figure 1 and Figure 2 The device includes a telescopic mobile frame 1, a crack repair component 2, and a slurry holding component 3. The telescopic mobile frame 1 includes a base 4, a fixed frame 5, and a movable frame 6. The lower surface of the base 4 is provided with casters with a braking function, while the fixed frame 5 is vertically arranged on the upper surface of the base 4. The movable frame 6 is slidably arranged at the end of the movable frame 6 away from the base 4 and can slide along the length direction of the fixed frame 5. The crack repair component 2 is installed on the movable frame 6, while the slurry holding component 3 is installed on the fixed frame 5.

[0033] The crack repair assembly 2 includes a rotating frame 7, a repair roller 8, and a repair block 9. The rotating frame 7 is mounted on the movable frame 6. When the rotating frame 7 rotates, the repair roller 8 and the repair block 9 can alternately appear above the paste-holding assembly 3, thereby allowing the repair roller 8 and the repair block 9 to alternately enter the paste-holding assembly 3 to absorb the putty used to repair the wall.

[0034] The rotating frame 7 includes a rotating shaft 10, mounting rod 11, mounting rod 2 12, and two connecting plates 13. The rotating shaft 10 is rotatably mounted on the movable frame 6, with its axis parallel to the ground. The rotating shaft 10 can rotate around its own axis on the movable frame 6. The two connecting plates 13 are respectively installed at both ends of the length of the rotating shaft 10 and can rotate together with the rotating shaft 10. Mounting rod 11 and mounting rod 2 12 are both installed between the two connecting plates 13. Mounting rod 11 and mounting rod 2 12 are symmetrically distributed on both sides of the rotating shaft 10 about its axis and are perpendicular to the rotating shaft. 10. Parallel, the repair roller 8 is mounted on the mounting rod 11 and can rotate around its own axis. After the crack is repaired, it can slide along the length of the crack by the fixed frame 5 on the base 4, thereby smoothing the repaired area to ensure the flatness of the surface. Similarly, the repair block 9 is mounted on the mounting rod 22 and can slide back and forth along the length of the mounting rod 22. This allows the repair block 9 to smooth the repaired area by sliding back and forth on the mounting rod 22 after the crack is repaired, thus ensuring the flatness of the repaired area.

[0035] In order to adjust the rotation angle of the rotating shaft 10 on the movable frame 6, a drive assembly 14 for driving the rotating shaft 10 is provided on the movable frame 6. The drive assembly 14 includes a drive actuator 15, a drive wheel 16, and a driven wheel 17. The drive actuator 15 is a stepper motor with a braking function. The drive wheel 16 is mounted on the output shaft of the drive actuator 15, and the driven wheel 17 is mounted on the rotating shaft 10. The drive wheel 16 and the driven wheel 17 are driven by a belt drive. When the drive actuator 15 is started, it will drive the drive wheel 16 to rotate. The drive wheel 16 will then drive the driven wheel 17 to rotate together through the transmission belt to realize the rotation of the connecting shaft. Subsequently, by starting and stopping the drive actuator 15, the rotation angle of the rotating shaft 10 can be adjusted. This allows the angle between the connecting plate 13 and the area to be repaired when the repair roller 8 and the repair block 9 come into contact with the area to be repaired to be adjusted. This allows the rotation distance of the repair roller 8 and the repair block 9 on the movable frame 6 to be adjusted according to the actual situation.

[0036] In other embodiments, the drive actuator 15 can also be directly connected to the rotating shaft 10 via a coupling to enable the rotating shaft 10 to rotate about its own axis.

[0037] Furthermore, in order to realize the reciprocating motion of the repair block 9 on the second mounting rod 12, a pusher 18 is provided on one of the connecting plates 13. The pusher 18 is a miniature electric push rod. The extension direction of the movable end of the pusher 18 is parallel to the second mounting rod 12. The pusher 18 is fixed on the connecting plate 13 and the movable end is fixedly connected to the pusher block. The pusher 18 is located between the second mounting rod 12 and the rotating shaft 10. This ensures that when the repair block 9 needs to be re-adhere putty in the putty holding assembly 3, the pusher 18 will not be contaminated with the putty in the putty holding assembly 3.

[0038] Reference Figure 1 and Figure 2 In order to facilitate the sliding of the fixed frame 5 on the base 4, a guide groove extending along the length of the base 4 is provided on the base 4. The end of the fixed frame 5 away from the movable frame 6 is located in the guide groove, and a second pusher 19 is provided in the guide groove. The second pusher 19 is also an electric push rod. The second pusher 19 is fixedly installed in the guide groove on the base 4, and the movable end of the second pusher 19 is connected to the fixed frame 5. This allows the fixed frame 5 to slide on the base 4 under the push of the second pusher 19.

[0039] Reference Figure 2 , Figure 3 and Figure 4 The pulp holding assembly 3 includes a pulp holding box 20 and a lifting member 21. The lifting member 21 is an electric push rod, which is mounted on a fixed frame 5. The movable end of the lifting member 21 is connected to the pulp holding box 20. Sliding grooves 23 are provided on the sides of both the fixed frame 5 and the movable member. The extending direction of the sliding grooves 23 is consistent with the length direction of the fixed frame 5 and the movable frame 6. The pulp holding box 20 is provided with a sliding part 24 that matches the sliding groove 23. When the lifting member 21 drives the pulp holding box 20 to rise or fall, the sliding part 24 slides within the sliding groove 23. This ensures that the lifting direction of the pulp holding box 20 will not easily change when the lifting member 21 drives the pulp holding box 20 to rise or fall. The sliding groove 23 limits the sliding part 24. This serves to guide and limit the putty container 20. Simultaneously, the lifting mechanism 21 changes the distance between the putty container 20 and the repair roller 8 or repair block 9. This allows the distance between the putty container 20 and the repair roller 8, or between the putty container 20 and the repair block 9, to be shortened by lifting the putty container 20 when it contains sufficient putty, provided there is enough putty. This prevents excess putty adhering to the repair roller 8 and repair block 9 from easily spilling onto the ground, eliminating the need for subsequent cleanup and reducing the workload for workers.

[0040] In other embodiments, the pusher 18, pusher 29, and lifting member 21 may also be hydraulic cylinders.

[0041] Furthermore, scraper plates 22 are provided on two parallel inner walls in the slurry container 20 along their length. A gap is left between the two scraper plates for the repair roller 8 and the repair block 9 to enter and exit the slurry container 20. This allows the excess putty adhering to the repair roller 8 and the repair block 9 to be initially scraped off by the scraper plates 22 when they enter and exit the slurry container 20, thereby reducing the risk of putty dripping onto the ground due to excessive putty at the repaired area.

[0042] The implementation principle of this application embodiment is as follows: When it is necessary to repair the cracks on the ceiling, the base 4 is moved to the bottom of the crack and the position of the base 4 is fixed. Then, the movable frame 6 extends from the fixed frame 5. When the movable frame 6 rises to near the ceiling, the extension length of the movable frame 6 on the fixed frame 5 is fixed. At this time, the repair roller 8 is located below the repair block 9. The lifting component 21 is activated so that the slurry box 20 can slide along the extension length of the fixed frame 5 and the movable frame 6 until the repair roller 8 enters the slurry box 20. Then, the lifting component drives the slurry box 20 to descend a certain height, leaving room for the repair roller 8 to rotate. Then, the drive actuator 15 is activated to drive the rotating shaft 10 to rotate around its own axis, so that the repair roller 8 rotates to a position close to the ceiling surface. Then, the height of the movable frame 6 is raised so that the repair roller 8 abuts against the ceiling. Then, the push component 2 19 is activated to drive the fixed frame 5 to move on the base 4 so that the repair roller 8 can repair along the cracks on the ceiling.

[0043] When it is necessary to repair the crack at the connection between the ceiling and the wall, the movable base 4 is moved to a position close to the wall and fixed. Then, by raising and lowering the grout box 20, the repair block 9 can adhere to the grout in the grout box 20. Then, the height of the grout box 20 is lowered, and the repair block 9 rotates under the drive of the rotating shaft 10. When the repair block 9 rotates and raises the height of the movable frame 6 on the fixed frame 5, the second pusher 19 is activated, so that the fixed frame 5 moves closer to the wall on the base 4. This allows the repair block 9 to contact the ceiling and the wall surface at the same time. If the direction of the crack to be repaired is perpendicular to the connection between the ceiling and the wall, the first pusher 18 pushes the repair block 9 to slide back and forth on the second mounting rod 12 along the axis of the second mounting rod 12 to repair and polish the crack at the connection between the ceiling and the wall. If the direction of the crack to be repaired is parallel to the connection between the ceiling and the wall, the first pusher 18 can also push the repair block 9 to repair the crack.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
