Description

Technical Field

[0001] This application relates to the field of ancient wall restoration, and in particular to a restoration device and method for ancient building walls. Background Technology

[0002] Ancient buildings are an important part of my country's historical relics. Protecting and restoring ancient buildings is one of the important tasks in cultural relic protection. The restoration and protection of ancient buildings take different approaches due to the differences in the historical value, historical status, architectural quality, degree of damage, and cultural and historical environment of the protected buildings.

[0003] Because ancient buildings are generally quite old, after prolonged exposure to sun and rain, some walls may develop cracks, damage, or even breakage. For walls with significant damage, they are usually dismantled and rebuilt to form new walls. For walls with minor damage, newly made bricks are used to fill the damaged areas. The craftsman first needs to determine the area of ​​the wall to be repaired, which is usually matched with the size and shape of the new bricks. Then, the new bricks are processed. After the bricks are prepared, the craftsman uses tools such as hammers or pliers to dig out a portion of the damaged wall bricks. After digging, the area is cleaned and then filled with mortar. The new bricks are then inserted. After the mortar dries completely, the wall is polished with a grinding head, thus completing the repair of the damaged wall.

[0004] When restoring ancient building walls, the principle of minimal intervention should generally be followed. This means that areas not severely weathered should be protected. This requires that when excavating broken bricks, the surrounding bricks should not be damaged. However, in practice, wall excavation is done manually. When excavating, the operator may deviate from the planned area, easily damaging the surrounding bricks and thus the original appearance of the ancient building's walls. Summary of the Invention

[0005] In order to solve the problems existing in the above-mentioned technologies, this application provides a repair device and repair method for ancient building walls.

[0006] The technical solution for a repair device for ancient building walls provided in this application is as follows: A repair device for ancient building walls includes a support frame with a mounting base horizontally slidable on it. A first driving member is provided on the support frame to drive the mounting base to slide. Two first side panels and two second side panels are slidably mounted on the mounting base. Guide angles are provided on the sides of the two first and two second side panels facing the wall. The two first side panels are arranged opposite to each other and parallel to each other. A second driving member is provided on the mounting base to drive the two first side panels to slide in directions that move away from or towards each other. The two second side panels are arranged opposite to each other and parallel to each other. A third driving member is provided on the mounting base to drive the two second side panels to slide in directions that move away from or towards each other. The sliding directions of the two first side panels and the two second side panels are perpendicular.

[0007] By adopting the above technical solution, when it is necessary to repair a damaged wall, the operator first determines the area of ​​the wall to be repaired, then places the support frame near the wall to be repaired, so that the two first and two second side panels are abutting against the wall to be repaired. Subsequently, the second driving component drives the two first side panels to slide, so that the two first side panels slide to the boundary of the repair area. Then, the third driving component drives the two second side panels to slide, so that the two second side panels also slide to the boundary of the repair area. Thus, the two first and two second side panels are all at the boundary of the repair area, and are respectively located on the two faces, top surface, and bottom surface of the repair area facing the wall. Throughout the process of excavating broken bricks, guide angles are provided on the side of the first and second enclosures facing the wall. When the operator excavates, they can dig with the guide angles facing the wall. The first drive component can then drive the mounting base according to the excavation, causing the mounting base to slide horizontally along the side closest to the wall. This allows the two first and two second enclosures to continuously slide inward toward the excavation site. As a result, the operator can always perform the excavation within the range of the two first and two second enclosures, ensuring that the excavation range remains within the planned range without significant deviation, while also avoiding damage to the bricks surrounding the broken bricks.

[0008] Optionally, the mounting base is provided with a telescopic component, and the telescopic component is provided with a vertical retaining block, wherein the first enclosure or the second enclosure is perpendicular to the vertical retaining block.

[0009] By adopting the above technical solution, in the initial state, the operation of the telescopic component ensures that the wall-facing surface of the vertical retaining block is on the same plane as the wall-facing side of the first or second enclosure. When repairing the damaged wall, the support frame is placed near the wall to be repaired until the vertical retaining block abuts against the wall. At this time, the first or second enclosure abuts against the wall, the wall-facing surface of the vertical retaining block is parallel to the wall, and the first or second enclosure is perpendicular to the wall. During wall repair, the movement of the mounting base drives the first and second enclosures to slide, and the telescopic component extends and retracts during this process, keeping the position of the vertical retaining block unchanged and always abutting against the wall. The vertical retaining block facilitates the positioning of the first and second enclosures, ensuring that the first and second enclosures are perpendicular to the wall, thus preventing deviations from the planned range during subsequent movement of the first and second enclosures.

[0010] Optionally, the telescopic component includes a hollow tube disposed on the mounting base, a movable rod disposed on the vertical retaining block, the movable rod being located inside the hollow tube and slidably connected to the hollow tube coaxially; a push spring is disposed inside the hollow tube, and the end of the push spring abuts against the movable rod.

[0011] By adopting the above technical solution, in the initial state, the elastic force of the push spring drives the side of the vertical retaining block facing the wall to be on the same plane as the side of the first or second enclosure facing the wall. During the wall repair process, the movement of the mounting base causes the push spring to be continuously compressed, and the vertical retaining block is always in contact with the wall.

[0012] Optionally, a positioning pin is inserted into the vertical retaining block, and a positioning hole is provided on the first or second enclosure for the positioning pin to be inserted. When the positioning pin is inserted into the positioning hole, the side of the vertical retaining block facing the wall is on the same plane as the side of the first or second enclosure facing the wall.

[0013] By adopting the above technical solution, the setting of the positioning pin is conducive to the initial positioning of the vertical retaining block, ensuring that the vertical retaining block can abut against the wall in the initial state, and at this time, the side of the first or second enclosure plate facing the wall also abuts against the wall.

[0014] Optionally, the vertical retaining block is attached to the first or second enclosure plate, and a guide block is provided on the vertical retaining block. The first or second enclosure plate is provided with a guide groove that slides with the guide block.

[0015] By adopting the above technical solution, through the cooperation of the guide block and the guide groove, the vertical retaining block not only plays an auxiliary positioning role, but also restricts the movement direction of the side or the second enclosure, thereby improving the stability of the first enclosure or the second enclosure during the movement of the mounting base and preventing the first enclosure or the second enclosure from being misaligned during the movement.

[0016] Optionally, the support frame includes a support plate, the first driving member is disposed on the support plate, a horizontal plate is fixed to one end of the support plate away from the mounting base, and a reinforcing plate is disposed between the support plate and the horizontal plate.

[0017] By adopting the above technical solution, the cooperation of the support plate and the horizontal plate supports the first driving component and the mounting base. When the entire repair device is placed near the wall to be repaired, the horizontal plate is in contact with the nearby ground to ensure the verticality of the support plate, while the reinforcing plate plays an auxiliary supporting role, strengthening the tightness of the connection between the support plate and the horizontal plate, thereby improving the stability of the entire repair device when it is placed.

[0018] Optionally, the reinforcing plate is hinged to the horizontal plate, and a sleeve is hinged to the support plate. An adjusting screw is threaded into the sleeve, and the end of the adjusting screw is hinged to the reinforcing plate.

[0019] By adopting the above technical solution, when the damaged part of the wall is high up, the operator needs to use a special climbing frame to reach the part that needs to be repaired. At this time, the repair device can be fixed by the top of the wall. By rotating the adjusting screw, the distance between the reinforcing plate and the support plate can be adjusted, so that the top of the wall can be clamped and fixed between the reinforcing plate and the support plate. At this time, the position of the support plate will not affect the position of the climbing frame, further improving the overall applicability of the repair device. When the repair device is placed on the ground, the distance between the reinforcing plate and the support plate can also be increased by rotating the adjusting screw until the end of the reinforcing plate abuts against the support plate, thereby providing auxiliary support through the reinforcing plate.

[0020] Optionally, the support base is provided with a grouting chamber, and grouting cavities are opened in both the first and second enclosures. The grouting cavities are connected to the grouting chambers through pipelines. Grouting ports are opened on the surfaces of both the first and second enclosures facing the wall, and the grouting ports (23) are connected to the grouting cavities.

[0021] By adopting the above technical solution, after the excavation of the damaged wall is completed, the operator needs to add mortar to the damaged area and then insert new bricks. After the new bricks are inserted, the mounting base can be moved away from the wall by the first driving component, so that the two first enclosures and two second enclosures are away from the wall. During this process, mortar can be injected into the grouting chamber. The mortar is transported to the first enclosure and the grouting cavity on the top through the pipeline, and then discharged into the wall through the grouting port. This can fill the gaps in the wall with mortar and improve the tightness of the new bricks in the wall.

[0022] Optionally, multiple grouting ports are provided at intervals on the surfaces of the first and second enclosures facing the wall.

[0023] By adopting the above technical solution, the coverage area of ​​mortar can be further increased by opening multiple grouting ports, while also improving the efficiency of mortar replenishment.

[0024] This application also discloses a method for repairing ancient building walls, using the aforementioned repair device for ancient building walls, comprising the following steps: S1: Determine the area of ​​the wall that needs to be repaired, and place the support frame near the wall that needs to be repaired, so that the side of the two first panels and the two second panels facing the wall are against the wall that needs to be repaired. S2: The second driving member drives the two first enclosures to slide, so that the two first enclosures slide to the boundary of the repair area; the third driving member drives the two second enclosures to slide, so that the two second enclosures slide to the boundary of the repair area. S3: The operator performs the excavation of broken bricks. The first drive component drives the mounting base according to the excavation, causing the two first and two second side plates to slide continuously toward the interior of the excavation site.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The operator can always carry out excavation work within the range of the two first walls and two second walls. The operator can also use the two first walls and two second walls as guide surfaces to carry out side excavation work, thereby ensuring that the excavation range is kept within the planned range and there will be no large deviation, while avoiding damage to the bricks around the broken bricks. 2. During wall repair, the movement of the mounting base causes the first and second enclosure panels to slide. The telescopic components extend and retract during this process, ensuring that the position of the vertical retaining block remains unchanged and always abuts against the wall. The vertical retaining block helps to position the first and second enclosure panels, ensuring that they are perpendicular to the wall. This prevents the first and second enclosure panels from deviating from the planned range during subsequent movement. 3. After the excavation of the damaged wall is completed, the operator needs to add mortar to the damaged area and then insert new bricks. After the new bricks are inserted, the mounting base can be moved away from the wall by the first drive component, so that the two first and two second enclosures are away from the wall. During this process, mortar can be injected into the grouting chamber. The mortar is transported to the first enclosure and the grouting cavity on the top through the pipeline, and then discharged into the wall through the grouting port. This can fill the gaps in the wall with mortar and improve the tightness of the new bricks in the wall. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] Example 1 Embodiment 1 of this application discloses a repair device for ancient building walls. (Refer to...) Figure 1 and Figure 2The ancient building wall restoration device includes a support frame 1, a mounting base 2 horizontally mounted on the support frame 1, a first driving member 3 for driving the mounting base 2 to slide on the support frame 1, two first enclosure plates 4 and two second enclosure plates 5 slidably mounted on the mounting base 2, and a pointed guide angle 8 opened on the side of the two first enclosure plates and the two second enclosure plates facing the wall. The two first enclosure plates 4 are arranged opposite to each other and parallel to each other. A second driving member 6 for driving the two first enclosure plates 4 to slide in a direction away from or close to each other is provided on the mounting base 2. The two second enclosure plates 5 are arranged opposite to each other and parallel to each other. A third driving member 7 for driving the two second enclosure plates 5 to slide in a direction away from or close to each other is provided on the mounting base 2. The sliding directions of the two first enclosure plates 4 and the two second enclosure plates 5 are perpendicular to each other.

[0030] Reference Figure 1 and Figure 2 The support frame 1 includes a support plate 15, which includes a fixed plate 151 and a movable plate 152. The movable plate 152 is slidably engaged with the fixed plate 151. The side wall of the fixed plate 151 has multiple second limiting holes 155 along its length. The movable plate 152 has a first limiting hole 154, and a fixing pin 153 is inserted into the first limiting hole 154. The fixing pin 153 is inserted into any of the second limiting holes 155. Both the fixed plate 151 and the movable plate 152 are... A vertical plate and a fixed plate 151 are fixed at the bottom of a horizontal plate 16. A reinforcing plate 17 is hinged to the end of the horizontal plate 16 away from the fixed plate 151. Two opposing connecting plates 25 are fixed on the fixed plate 151. A sleeve 18 is hinged between the two connecting plates 25 by a pin. An adjusting screw 19 is threaded into the sleeve 18. A rotating wheel 20 is fixed on the adjusting screw 19 so that it can be rotated by the operator. The end of the adjusting screw 19 is connected to the reinforcing plate 17 through a ball joint seat 24. When the damaged area of ​​the wall is low, the entire repair device is placed near the wall to be repaired, with the horizontal plate 16 flush with the nearby ground to ensure the verticality of the support plate 15, while the reinforcing plate 17 provides auxiliary support. When the damaged area of ​​the wall is high, the operator needs to use a special climbing frame to reach the area to be repaired. In this case, the repair device can be fixed at the top of the wall. The distance between the reinforcing plate 17 and the support plate 15 can be adjusted by rotating the adjusting screw 19, so that the top of the wall can be clamped and fixed between the reinforcing plate 17 and the support plate 15.

[0031] Reference Figure 1 The first driving component 3 includes a horizontally arranged telescopic rod 31 mounted on the movable plate 152. The telescopic rod 31 is an electric telescopic rod. The fixed end of the telescopic rod 31 is fixedly connected to the movable plate 152, and the movable end of the telescopic rod 31 is fixedly connected to the mounting base 2. The telescopic rod 31 moves to drive the mounting base 2 to slide along the excavation depth direction.

[0032] Reference Figure 1 and Figure 2 The second driving component 6 includes a horizontal frame 61 fixed to the mounting base 2. A first bidirectional lead screw 63 is rotatably connected to the horizontal frame 61. A first motor 62 is mounted on the horizontal frame 61. The output shaft of the first motor 62 is coaxially and fixedly connected to the first bidirectional lead screw 63. A slider is fixed to each of the two lead screw nuts of the first bidirectional lead screw 63. The two sliders are fixedly connected to the two first enclosure plates 4 respectively. The rotation of the output shaft of the first motor 62 drives the first bidirectional lead screw 63 to rotate, which further drives the two sliders to slide in the horizontal frame 61, thereby causing the two first enclosure plates 4 to slide in directions that are moving away from or close to each other.

[0033] Reference Figure 1 and Figure 2 The third driving component 7 includes a vertical frame 71 fixed to the mounting base 2. The vertical frame 71 is perpendicular to the horizontal frame 61. A second bidirectional lead screw 73 is rotatably connected to the vertical frame 71. A second motor 72 is mounted on the vertical frame 71. The output shaft of the second motor 72 is coaxially and fixedly connected to the second bidirectional lead screw 73. A slider is fixed to each of the two lead screw nuts of the second bidirectional lead screw 73. The two sliders are fixedly connected to the two second enclosure plates 5 respectively. The rotation of the output shaft of the second motor 72 drives the second bidirectional lead screw 73 to rotate, which further drives the two sliders to slide in the vertical frame 71, thereby causing the two second enclosure plates 5 to slide in directions away from or close to each other.

[0034] Reference Figure 3 and Figure 4Hollow tubes 26 are installed on the sliders of the first bidirectional lead screw 63 and the second bidirectional lead screw 73. A movable rod 27 is coaxially slidably connected inside the hollow tube 26. A push spring 10 is installed inside the hollow tube 26. One end of the push spring 10 is fixedly connected to the hollow tube 26, and the other end is fixedly connected to the movable rod 27. A vertical holding block 9 is fixed to the end of the movable rod 27. A positioning pin 11 is inserted into the vertical holding block 9. A positioning hole 12 for the positioning pin 11 to be inserted is opened on the corresponding first enclosure 4 or second enclosure 5. In the initial state, the positioning pin 11 is inserted into the positioning hole 12. At this time, the side of the vertical holding block 9 facing the wall is aligned with the side of the corresponding first enclosure 4 or second enclosure 5 facing the wall. When repairing a damaged wall on the same plane, the support frame 1 is placed near the wall to be repaired until the vertical retaining block 9 abuts against the wall to be repaired. At this time, the first enclosure 4 or the second enclosure 5 abuts against the wall to be repaired, the face of the vertical retaining block 9 facing the wall is parallel to the wall to be repaired, and the first enclosure 4 or the second enclosure 5 is perpendicular to the wall. When repairing the wall, the movement of the mounting base 2 drives the first enclosure 4 and the second enclosure 5 to slide. The movement of the mounting base 2 causes the push spring 10 to be continuously compressed. The position of the vertical retaining block 9 remains unchanged and always abuts against the wall. The vertical retaining block 9 facilitates the positioning of the first enclosure 4 and the second enclosure 5, ensuring that the first enclosure 4 and the second enclosure 5 are perpendicular to the wall.

[0035] Reference Figure 3 and Figure 5 The vertical retaining block 9 is attached to and slidably engaged with the corresponding first enclosure 4 or second enclosure 5. A guide block 13 is provided on the vertical retaining block 9, and a guide groove 14 is provided on the corresponding first enclosure 4 or second enclosure 5 to slidably engage with the guide block 13. The guide block 13 is located within the guide groove 14. Through the cooperation of the guide block 13 and the guide groove 14, the vertical retaining block 9, in addition to its auxiliary positioning function, also restricts the movement direction of the side or second enclosure 5.

[0036] Reference Figure 3 and Figure 5A grouting chamber 21 is installed on the support base. The grouting chamber 21 has an inlet for injecting mortar. The grouting chamber 21 has a cavity for storing and transferring mortar. Grouting chambers 22 are provided in both first enclosures 4 and second enclosures 5. Multiple grouting ports 23 are spaced apart on the surfaces of the two first enclosures 4 and second enclosures 5 facing the wall. The grouting ports 23 are connected to the grouting chambers 22. The grouting chambers 22 are connected to the grouting chambers 21 through pipelines. After the excavation of the damaged wall is completed, the operator needs to add mortar to the damaged area and then insert new bricks. After the new bricks are inserted, the mounting base 2 can be moved away from the wall by the telescopic rod 31, so that the two first enclosures 4 and the two second enclosures 5 are away from the wall. During this process, mortar can be injected into the grouting chamber 21. The mortar is transported to the first enclosure 4 and the grouting cavity 22 on the top through the pipeline, and then discharged into the wall through the grouting port 23. This allows the mortar to be added to the gaps in the wall.

[0037] The implementation principle of the ancient building wall repair device in Embodiment 1 of this application is as follows: When a damaged wall needs to be repaired, the operator first determines the area of ​​the wall to be repaired, and then places the support frame 1 near the wall to be repaired, so that the two first enclosure plates 4 and the two second enclosure plates 5 are abutting against the wall to be repaired. Subsequently, the rotation of the output shaft of the first motor 62 drives the first bidirectional lead screw 63 to rotate, further driving the two sliders to slide in the horizontal frame 61, thereby driving the two first enclosure plates 4 to slide to the boundary of the repair area; similarly, the rotation of the output shaft of the second motor 72 then drives the two second enclosure plates 5 to slide, so that the two second enclosure plates 5 also slide to the boundary of the repair area; thus, the two first enclosure plates 4 and the two second enclosure plates 5 are all at the boundary of the repair area, and are respectively located on both sides of the repair area. During the entire process of the operator digging out broken bricks on the front, top, and bottom surfaces of the wall, the first and second enclosure plates 4 and 5 are provided with guide angles 8 facing the wall. When the operator digs, they can dig with the guide angles 8 facing the wall. The telescopic rod 31 drives the mounting base 2 according to the digging situation, so that the mounting base 2 slides horizontally along the side close to the wall. This causes the two first enclosure plates 4 and two second enclosure plates 5 to continuously slide towards the inside of the digging area. This allows the operator to always dig within the range of the two first enclosure plates 4 and two second enclosure plates 5. The operator can also use the two first enclosure plates 4 and two second enclosure plates 5 as guide surfaces to dig on the sides, thereby ensuring that the digging range remains within the planned range and does not deviate significantly, while avoiding damage to the bricks around the broken bricks.

[0038] Example 2 Example 2 discloses a method for repairing ancient building walls, using a repair device for ancient building walls from Example 1, including the following steps: S1: Determine the area of ​​the wall to be repaired. When the repair device is placed near the wall to be repaired, the fixing plate 151 is supported by the cooperation of the reinforcing plate 17 and the horizontal plate 16 to fix the repair device. Then, the two first enclosure plates 4 and the two second enclosure plates 5 are all abutted against the wall to be repaired on the side facing the wall. The vertical holding blocks 9 corresponding to the two first enclosure plates 4 and the two second enclosure plates 5 are provided with positioning pins 11, which are inserted into the corresponding positioning holes 12. S2: Drive the first motor 62 to operate, thereby driving the first bidirectional lead screw 63 to rotate, so that the two first enclosure plates 4 slide to the boundary of the repair area; drive the second motor 72 to operate, thereby driving the second bidirectional lead screw 73 to rotate, so that the two second enclosure plates 5 slide to the boundary of the repair area. S3: The operator performs the excavation of the broken bricks, removes multiple positioning pins 11 from the positioning holes 12, and the telescopic rod 31 drives the mounting base 2 according to the excavation, so that the two first enclosure plates 4 and the two second enclosure plates 5 continuously slide toward the inside of the excavation site. S4: After the excavation work is completed, the operator adds mortar to the damaged area and then inserts the newly made brick. S4: The telescopic rod 31 drives the mounting base 2 to move away from the wall, thereby moving the two first enclosures 4 and the two second enclosures 5 away from the wall and simultaneously injecting mortar into the grouting chamber 21. The mortar is transported through the pipeline to the first enclosure 4 and the grouting cavity 22 on the top, and then discharged into the wall through the grouting port 23.

[0039] S4: After the plaster has set, polish the wall surface.

[0040] 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.
