We should view and protect ancient architecture and its cultural characteristics from a developmental perspective, so as to preserve ancient architectural culture to the world and generate modern value for ancient cultural heritage.
[0003] Currently, operators frequently need to use crack repair devices when maintaining ancient buildings. However, while existing crack repair devices have basic functions such as the nozzles being able to move up and down and back and forth, the nozzles cannot be adjusted in angle. This makes it difficult for operators to repair cracks at different angles, causing inconvenience. Therefore, improvements are needed. Utility Model Content

[0006] As a preferred embodiment of this utility model, pneumatic cylinders are fixedly connected to both the left and right sides of the bottom end of the long plate, and a movable plate is fixedly installed at the bottom end of the pneumatic cylinder.
[0007] As a preferred embodiment of this utility model, the bottom end of the movable plate is movably connected to a base, and self-locking casters are movably installed at the four corners of the bottom end of the base.
[0008] As a preferred embodiment of this utility model, a handle is fixedly connected to the right side of the base, and the outer surface of the handle is rough.
[0009] As a preferred embodiment of this utility model, a second motor is fixedly installed on the right side of the long plate, and a rotating shaft is fixedly sleeved on the other end of the output shaft of the second motor.
[0010] As a preferred embodiment of this utility model, a long rod is fixedly sleeved on the outer surface of the rotating shaft, and a moving rod is hinged to the other end of the long rod. The other end of the moving rod is hinged to the right side of the movable block.
[0011] As a preferred embodiment of this utility model, a guide block located inside the long plate is fixedly installed at the bottom end of the movable block, and the outer surface of the guide block is movably connected to the interior of the long plate.
[0012] As a preferred technical solution of this utility model, a third motor is fixedly installed on the back of the base, and a lead screw is fixedly sleeved on the other end of the output shaft of the third motor.

[0013] As a preferred technical solution of this utility model, the outer surface of the lead screw is threaded with a limiting block located inside the base, and the top end of the limiting block is fixedly connected to the bottom end of the movable plate.
[0014] As a preferred technical solution of this utility model, the outer surface of the limiting block is movably connected to the interior of the base, and the outer surface of the lead screw and the interior of the base are both smooth.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. In this disclosure, by setting up a first gear, a first motor, a rotating shaft, and a second gear, the operator starts the first motor, which causes the rotating shaft to drive the second gear to rotate together. This causes the outer surface of the second gear to mesh with the outer surface of the first gear, which in turn enables the first gear to drive the round shaft, rotating block, and rectangular block to adjust their angles as a whole. This allows the operator to fill and repair cracks at different angles during operation, thereby improving the application range of the crack repair device.
[0017] 2. In this disclosure, by setting up a second motor, a rotating shaft, a long rod, and a moving rod, the operator starts the second motor, which causes the rotating shaft to rotate along with the long rod, thereby causing the moving rod to push the movable block to move to the left. Subsequently, the operator runs the second motor again, which causes the rotating shaft to flip, thereby causing the movable block to move to the right. This operation allows the operator to more accurately guide and locate the cracks when repairing cracks in ancient buildings, thus bringing convenience to the operator's actual work.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to 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 disclosure.
[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5As shown, a crack repair device for an ancient building structure according to an embodiment of the present disclosure is illustrated. It includes a long plate 1, a movable block 2 movably connected to the top of the long plate 1, a connecting block 3 fixedly installed at the top of the movable block 2, a circular shaft 4 movably connected to the inside of the right side of the connecting block 3, the left end of the circular shaft 4 passing through the connecting block 3 and extending to the outside of the left side of the connecting block 3, and a first gear 8 fixedly sleeved on its outer surface, a rotating block 5 located between the inner surfaces of the connecting block 3 fixedly sleeved on the outer surface of the circular shaft 4, a rectangular block 6 fixedly connected to the front of the top of the rotating block 5, a nozzle 7 fixedly installed inside the rectangular block 6, the front and back of the nozzle 7 passing through the rectangular block 6 and extending to the outside of the front and back of the rectangular block 6 respectively, a first motor 9 fixedly installed on the left side of the movable block 2, a rotating shaft 10 fixedly sleeved at the other end of the output shaft of the first motor 9, a second gear 11 fixedly sleeved on the outer surface of the rotating shaft 10, and the outer surface of the second gear 11 meshing with the outer surface of the first gear 8.
[0032] Since the connection between the second gear 11 and the first gear 8 is meshed, when the second gear 11 rotates, the first gear 8 will rotate along with it. Due to the design of the nozzle 7, the operator can fix the hose on the pump body to the back of the nozzle 7, so that the nozzle 7 can repair the crack through the filler. The first motor 9 also has a self-locking function.
[0033] In some examples, pneumatic cylinders 12 are fixedly connected to both the left and right sides of the bottom end of the long plate 1, and a movable plate 13 is fixedly installed at the bottom end of the pneumatic cylinder 12.
[0034] The design of the two pneumatic cylinders 12 enables the nozzle 7 to fill and repair cracks of different heights.
[0035] In some examples, the bottom of the movable plate 13 is movably connected to a base 14, and self-locking casters 15 are movably installed at the four corners of the bottom of the base 14.
[0036] When the four self-locking casters 15 rotate, they can drive the entire long plate 1 to move.
[0037] In some examples, a handle 16 is fixedly connected to the right side of the base 14, and the outer surface of the handle 16 is rough.
[0038] Due to the design of the handle 16, the operator can push the entire long plate 1 through the handle 16, thereby causing the four self-locking casters 15 to rotate.
[0039] In some examples, a second motor 17 is fixedly mounted on the right side of the long plate 1, and a rotating shaft 18 is fixedly sleeved on the other end of the output shaft of the second motor 17.
[0040] Because the second motor 17 has a self-locking function, it can remain stable even when the power is off.
[0041] In some examples, a long rod 19 is fixedly sleeved on the outer surface of the rotating shaft 18, and a moving rod 20 is hinged to the other end of the long rod 19. The other end of the moving rod 20 is hinged to the right side of the movable block 2.
[0042] Since the long rod 19 and the moving rod 20 are hinged, when the long rod 19 rotates, it will pull or push the moving rod 20.
[0043] In some examples, the bottom end of the movable block 2 is fixedly mounted with a guide block 21 located inside the long plate 1, and the outer surface of the guide block 21 is movably connected to the interior of the long plate 1.
[0044] Due to the design of the guide block 21, the movement of the movable block 2 is limited.
[0045] In some examples, a third motor 22 is fixedly mounted on the back of the base 14, and a lead screw 23 is fixedly sleeved on the other end of the output shaft of the third motor 22. The other end of the lead screw 23 passes through the base 14 and extends into the interior of the base 14 and is movably connected to the interior of the base 14.
[0046] Since both the outer surface of the lead screw 23 and the interior of the base 14 are smooth, the frictional loss generated on the outer surface when the lead screw 23 rotates inside the base 14 can be reduced.
[0047] In some examples, the outer surface of the lead screw 23 is threaded with a limiting block 24 located inside the base 14, and the top of the limiting block 24 is fixedly connected to the bottom of the movable plate 13.
[0048] Due to the design of the limit block 24, the movement of the movable plate 13 can be guided.
[0049] In some examples, the outer surface of the limit block 24 is movably connected to the interior of the base 14, and the outer surface of the lead screw 23 is smooth to the interior of the base 14.
[0050] Since both the outer surface of the lead screw 23 and the interior of the base 14 are smooth, the movement of the lead screw 23 inside the base 14 is smoother.
[0051] Working principle and usage process of this utility model:
[0052] First, the operator connects and secures the hose on the pump body to the back of the nozzle 7. Then, when the operator needs to guide and position the nozzle according to its location, the pneumatic cylinder 12, the third motor 22, and the second motor 17 are activated. The movement of the pneumatic cylinder 12 causes the long plate 1 to move upward, thereby moving the nozzle 7 to the corresponding height of the crack. The operation of the third motor 22 causes the lead screw 23 to rotate, thereby causing the limit block 24 to drive the movable plate 13 to move back and forth, thus adjusting the appropriate distance between the nozzle 7 and the crack. The movement of the second motor 17 causes the rotating shaft 18 and the long rod 19 to rotate, thereby causing the moving rod 20 to pull or push the movable block 2 to move to the left or right, thus positioning the crack. Then, the pump body is activated, so that the filler will be sprayed from the nozzle 7 into the crack through the hose.
[0053] Finally, when the operator needs to repair cracks at different angles, the operator starts the first motor 9, which will cause the rotating shaft 10 and the second gear 11 to rotate, so that the outer surface of the second gear 11 meshes with the outer surface of the first gear 8. This causes the first gear 8 to drive the round shaft 4, the rotating block 5 and the rectangular block 6 to change angle as a whole, so that the nozzle 7 can fill and repair cracks at different angles.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
