Description

Technical Field

[0001] The invention relates to the technical field of grouting pipe processing, and in particular to an internal grinding device and method for grouting pipe processing. Background Art

[0002] The grouting pipe is a tool used in construction engineering and geological engineering to inject slurry into soil, rock or structure to achieve the purpose of reinforcement, strengthening or leakage prevention. In order to improve the smoothness of the flow of grouting liquid in the grouting pipe, it is necessary to keep the inner wall of the grouting pipe smooth. Therefore, in the production process of the grouting pipe, an internal grinding device is required to grind and polish the inner wall of the grouting pipe.

[0003] Announcement No. CN110587415B discloses a pipe inner wall variable diameter grinding device, which includes a variable diameter grinding mechanism, a revolution drive component, a front displacement support mechanism and a front grinding support mechanism arranged at one end of the variable diameter grinding mechanism, and a rear displacement support mechanism and a rear grinding support mechanism arranged at the other end of the variable diameter grinding mechanism. The variable diameter grinding mechanism is used to grind the inner wall of the pipe, the front displacement support mechanism and the rear displacement support mechanism alternately provide axial displacement for the variable diameter grinding mechanism, and the front grinding support mechanism and the rear grinding support mechanism are used to provide radial support force.

[0004] The pipe inner wall variable diameter grinding device supports the variable diameter grinding mechanism through the front grinding support mechanism and the rear grinding support mechanism. The variable diameter grinding mechanism adjusts the active radius according to the pipes of different diameters and rotates under the drive of the revolution driving component to grind the weld nodules, welding slag and rust spots on the inner wall of the pipe to form a smooth surface. The front displacement support mechanism and the rear displacement support mechanism alternately provide axial displacement to complete the grinding of the entire inner wall of the pipe.

[0005] During the specific use of the pipeline inner wall grinding device, although the inner walls of pipelines with different diameters can be ground, the grinding efficiency is low due to the fixed rotation direction of the grinding wheel. At the same time, the grinding mechanism is supported on the inner wall of the pipeline by an internal support, which makes it impossible to grind the position close to the pipeline port. Secondly, the movement of the internal support inside the pipeline will have a certain impact on the inside of the pipeline, and the operation is relatively cumbersome. In addition, during the grinding process, the pressure cannot be adjusted according to the specific conditions inside the pipeline, and there is a situation where the grinding groove exceeds the limit or the grinding is insufficient, which affects the grinding quality.

[0006] Therefore, a novel internal grinding device and method for grouting pipe processing can be adopted to solve the shortcomings of the prior art. Summary of the invention

[0021] S1. First, place the grouting pipe on the bracket, then adjust the height of the grouting pipe so that the central axis of the grouting pipe and the central axis of the end limit plate are at the same horizontal height, and then lock the grouting pipe through the locking assembly;

[0022] S2, after the locking is completed, the fine grinding wheel 1, the fine grinding wheel 2, the cleaning wheel, the primary grinding wheel 1, the primary grinding wheel 2 and the pressure control plate are inserted into the grouting pipe through the driving component, and then the positions of the fine grinding wheel 1, the fine grinding wheel 2, the cleaning wheel, the primary grinding wheel 1, the primary grinding wheel 2 and the pressure control plate are adjusted through the adjusting component, so that the fine grinding wheel 1, the fine grinding wheel 2, the cleaning wheel, the primary grinding wheel 1 and the primary grinding wheel 2 are all against the inner wall of the grouting pipe, and then the fine grinding wheel 1, the fine grinding wheel 2, the cleaning wheel, the primary grinding wheel 1, the primary grinding wheel 2 and the pressure control plate are pulled out from the grouting pipe, so that the primary grinding wheel 1, the primary grinding wheel 2 and the pressure control plate are moved to the port position of the grouting pipe;

[0023] S3, then drive the end limit plate to rotate through the driving component, thereby drive the fine grinding wheel 1, fine grinding wheel 2, cleaning wheel, primary grinding wheel 1, primary grinding wheel 2 and pressure control disc to make circular motion around the center line of the end limit plate, so as to perform turnover grinding, and at the same time drive the fine grinding wheel 1, fine grinding wheel 2, primary grinding wheel 1 and primary grinding wheel 2 to rotate around their own axes through the rotating component, the rotation direction of the fine grinding wheel 1 is opposite to that of the fine grinding wheel 2, and the rotation direction of the primary grinding wheel 2 is opposite to that of the primary grinding wheel 1, so as to perform self-rotation grinding, thereby improving the grinding efficiency, and cooperating with the cleaning wheel to clean the inner wall after grinding;

[0024] S4. A jet gun is fixedly installed on the multiple support rods. Multiple nozzles are fixedly installed on the jet gun. The jet gun and the nozzles are used to perform jet cleaning from the middle to both sides to clean the debris from grinding to avoid the debris from affecting the grinding;

[0025] S5. As grinding progresses, there is an error in the thickness of the inner wall of the grouting pipe. At this time, the positions of fine grinding wheel one, fine grinding wheel two, cleaning wheel, primary grinding wheel one, primary grinding wheel two and pressure control plate can be adjusted by pressure regulating assembly to control the pressure between fine grinding wheel one, fine grinding wheel two, cleaning wheel, primary grinding wheel one, primary grinding wheel two and pressure control plate and the inner wall of the grouting pipe, thereby achieving constant pressure grinding and improving grinding quality.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. During the grinding process of the inner wall of the grouting pipe, the internal grinding device can automatically adjust the grinding distance according to the flatness of the inner wall of the grouting pipe. It is suitable for grinding grouting pipes of different sizes. At the same time, it can also automatically change the grinding pressure during the grinding process to ensure that the pressure is constant during the grinding process, which is conducive to improving the grinding quality and making the grinding more thorough.

[0028] 2. During the grinding process of the inner wall of the grouting pipe, the internal grinding device can keep the fine grinding wheel one, fine grinding wheel two, cleaning wheel, primary grinding wheel one, primary grinding wheel two and pressure control plate in a vertical state during the process of adjusting the positions of the fine grinding wheel one, fine grinding wheel two, cleaning wheel, primary grinding wheel one, primary grinding wheel two and pressure control plate by setting a rotating rod, a balancing rod and a disc, thereby avoiding tilting of the fine grinding wheel one, fine grinding wheel two, cleaning wheel, primary grinding wheel one, primary grinding wheel two and pressure control plate, and ensuring the contact area between the fine grinding wheel one, fine grinding wheel two, cleaning wheel, primary grinding wheel one, primary grinding wheel two and pressure control plate and the inner wall of the grouting pipe, thereby improving the grinding efficiency.

[0029] 3. During the process of grinding the inner wall of the grouting pipe, the internal grinding device drives the primary grinding wheel 1, primary grinding wheel 2, fine grinding wheel 1 and fine grinding wheel 2 to revolve and grind by setting a driving motor. At the same time, the primary grinding wheel 1, primary grinding wheel 2, fine grinding wheel 1 and fine grinding wheel 2 can be driven by a servo motor to rotate and grind. The rotation directions of the primary grinding wheel 1 and the primary grinding wheel 2, as well as the fine grinding wheel 1 and the fine grinding wheel 2 are opposite, which effectively improves the grinding efficiency. The primary grinding wheel 1 and the primary grinding wheel 2 are used for preliminary grinding, and then the fine grinding wheel 1 and the fine grinding wheel 2 are used for fine grinding. A time interval is left between the two grindings to reduce the influence of the thermal stress generated during the grinding process on the grouting pipe and improve the grinding quality.

[0030] To sum up, not only revolution grinding is adopted, but also rotation grinding is adopted, and the direction of rotation grinding is inconsistent, so as to improve the grinding quality and efficiency. At the same time, the position of the grinding wheel can be automatically adjusted according to the flatness of the inner wall of the grouting pipe to avoid grinding dead angles and make the grinding more thorough. In addition, during the grinding process, the pressure between the grinding wheel and the inner wall of the grouting pipe can be automatically changed according to the actual situation, so as to improve the grinding quality.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Example 1: Reference Figure 1 An internal grinding device for grouting pipe processing includes a bracket 1, a grouting pipe 4, a fixing frame 7 and a fixing frame 8; a fixing part is located on the bracket 1 and is used to lock the grouting pipe 4, and a locking component matching the grouting pipe 4 is installed on the bracket 1.

[0051] The locking assembly includes two side clamps 5 fixedly mounted on both sides of the bracket 1, and a screw is rotatably mounted on each of the two side clamps 5, and a stopper matched with the grouting pipe 4 is rotatably mounted on one end of the two screws close to the grouting pipe 4;

[0052] First, the grouting pipe 4 is placed on the bracket 1 , and then the screw is rotated to make the abutment plate abut against the grouting pipe 4 , thereby locking the grouting pipe 4 to prevent the grouting pipe 4 from moving during the grinding process and improve the stability of the grouting pipe 4 .

[0053] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 2-Figure 5The grinding part is installed on the fixing frame 1 7 and the fixing frame 2 8, and is used for grinding the inner wall of the grouting pipe 4. The grinding part includes a plurality of support rods 31 fixedly installed on the fixing frame 1 7 and the fixing frame 2 8. An end limit plate 25 is fixedly installed at both ends of the plurality of support rods 31. A driving assembly is installed between the bracket 1 and one of the end limit plates 25.

[0054] A jet tube 6 is fixedly mounted on the plurality of support rods 31, and a plurality of nozzles 17 are fixedly mounted on the jet tube 6. The jet tube 6 and the nozzles 17 are used to perform jet cleaning from the middle to both sides to clean the debris from grinding to avoid the debris affecting the grinding.

[0055] The driving assembly comprises an end support plate 2 fixedly mounted on the bracket 1, on which a hydraulic rod 3 is fixedly mounted, and a telescopic end of the hydraulic rod 3 is connected to one of the end limit plates 25 via a rotating mechanism.

[0056] The movement of the telescopic end of the hydraulic rod 3 will drive the end limit plate 25 to move through the rotating mechanism, thereby driving the movement of multiple support rods 31 to promote grinding. The purpose of using the hydraulic rod 3 is to improve sufficient reasoning and ensure the smooth advancement of grinding.

[0057] The rotating mechanism includes a pad 20 fixedly mounted on the telescopic end of the hydraulic rod 3, a mounting plate 21 is fixedly mounted on the pad 20 through a plurality of pillars, a driving motor 22 is fixedly mounted on the mounting plate 21, a connecting plate 23 is fixedly mounted on the mounting plate 21 through a plurality of supporting pillars, a rotating plate 24 is rotatably mounted on the connecting plate 23, a driving end of the driving motor 22 is fixedly connected to the rotating plate 24, and the rotating plate 24 is fixedly connected to an end limit plate 25 close to one side of the fixed frame 28;

[0058] The driving end of the driving motor 22 rotates to drive the rotating plate 24 fixedly connected thereto to rotate, thereby driving the end limit plate 25 to rotate, thereby driving the multiple support rods 31 to rotate, thereby realizing turnover grinding.

[0059] The combination of the pad 20 and the mounting plate 21 can form a structure similar to a protective cover, which is used to protect the drive motor 22. At the same time, the thrust of the hydraulic rod 3 directly acts on the pad 20 and the mounting plate 21 to prevent it from acting on the drive motor 22; the function of the connecting plate 23 is to limit the rotating plate 24 and the end limit plate 25, so that the components on the end limit plate 25 act on the connecting plate 23 instead of the driving end of the drive motor 22, thereby reducing the torque on the driving end of the drive motor 22 and ensuring the operating efficiency of the drive motor 22.

[0060] Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: Figure 3-Figure 8A plurality of rotating rods 10 are rotatably mounted on the fixed frame 7, a plurality of rotating rods 9 are rotatably mounted on the fixed frame 8, and adjustment components are mounted on both the fixed frame 7 and the fixed frame 8 corresponding to the plurality of rotating rods 10 and between the plurality of rotating rods 9.

[0061] The adjustment component includes a dual-axis motor 26 fixedly installed between a fixed frame 1 7 and a fixed frame 2 8, a screw rod 27 is rotatably installed on each of the fixed frame 1 7 and the fixed frame 2 8, a threaded sleeve 29 is threadedly rotatably installed on each of the two screw rods 27, a sliding frame 28 is fixedly installed on each of the two threaded sleeves 29, the two sliding frames 28 are slidably connected to a plurality of support rods 31, a connecting rod 30 is rotatably installed on each of the two sliding frames 28, the plurality of connecting rods 30 are rotatably connected to the corresponding rotating rod 1 9 and the rotating rod 2 10, and the two driving ends of the dual-axis motor 26 are fixedly connected to the corresponding screw rods 27.

[0062] The rotation of the driving end of the dual-axis motor 26 will drive the screw rod 27 to rotate, and the rotation of the screw rod 27 will cause the threaded sleeve 29 to move on the screw rod 27, thereby driving the sliding frame 28 to move along with the threaded sleeve 29. As the sliding frame 28 moves, the connecting rod 30 will be driven to move, thereby driving the rotating rod 1 9 and the rotating rod 2 10 to rotate around the corresponding fixed frame 1 7 and the fixed frame 2 8 through the connecting rod 30, so as to adjust the angles of the rotating rod 1 9 and the rotating rod 2 10, which is used to grind the inner wall of the grouting pipe 4 of different sizes and different flatness, and the scope of application is expanded.

[0063] Embodiment 4: This embodiment is different from the technical solution of embodiment 3 in that: Figure 9-13 A fine grinding wheel 14, a fine grinding wheel 15 and a cleaning wheel 16 are respectively installed on the multiple rotating rods 9, and a primary grinding wheel 11, a primary grinding wheel 12 and a pressure control plate 13 are respectively installed on the multiple rotating rods 10. A rotating assembly is installed between the fine grinding wheel 14, the fine grinding wheel 15 and the corresponding rotating rod 9, and between the primary grinding wheel 11, the primary grinding wheel 12 and the corresponding rotating rod 10.

[0064] The primary grinding wheel 11, the primary grinding wheel 2 12, the fine grinding wheel 14, and the fine grinding wheel 2 15 are collectively referred to as grinding wheels for the convenience of subsequent writing and use. The corresponding names will continue to be used where details are required.

[0065] The rotating assembly includes a rotating block 33 rotatably mounted on the rotating rod 1 9 and the rotating rod 2 10, and a rotating shaft is rotatably mounted on the rotating block 33. The rotating shaft is fixedly connected to the corresponding fine grinding wheel 14, fine grinding wheel 2 15, primary grinding wheel 1 11 and primary grinding wheel 2 12, and a driving mechanism is installed between each rotating shaft and the corresponding rotating rod 1 9 and rotating rod 2 10; the function of the rotating block 33 is to change the angle of the rotating shaft and the grinding wheel.

[0066] The driving mechanism includes a servo motor 18 fixedly mounted on a rotating rod 1 9 and a rotating rod 2 10, a resilient telescopic rod 1 35 is fixedly mounted on the driving end of each servo motor 18, a resilient telescopic rod 2 37 is fixedly mounted on each rotating shaft, and a universal coupling 36 is commonly installed between each resilient telescopic rod 1 35 and the corresponding resilient telescopic rod 2 37 driving end, the resilient telescopic rod 1 35, the resilient telescopic rod 2 37 and the universal coupling 36 are collectively referred to as a linkage assembly 34, which is convenient for writing descriptions.

[0067] The rotation of the driving end of the servo motor 18 will rotate the corresponding shaft through the linkage assembly 34. The specific rotation steps are: the rotation of the driving end of the servo motor 18 will drive the elastic telescopic rod 1 35 to rotate, thereby driving the elastic telescopic rod 2 37 to rotate through the universal joint 36, thereby driving the corresponding shaft to rotate, thereby driving the grinding wheel to rotate for self-rotation grinding. Since the grinding wheel will rotate around the rotating block 33, the distance between the rotating shaft and the servo motor 18 will change. At this time, the changed distance is compensated by the extension and shortening of the elastic telescopic rod 1 35 and the elastic telescopic rod 2 37.

[0068] A vertical mechanism is installed between each rotating block 33 and the corresponding fine grinding wheel 1 14, fine grinding wheel 2 15, cleaning wheel 16, primary grinding wheel 11, primary grinding wheel 2 12 and pressure control plate 13. The pressure control plate 13 is fixedly connected to the corresponding rotating shaft, and the cleaning wheel 16 is rotatably connected to the corresponding rotating shaft.

[0069] The cleaning wheel 16 is made of sponge material, and the rotation between the cleaning wheel 16 and the corresponding rotating shaft is a damped rotation. The friction force is not enough to drive the cleaning wheel 16 to rotate. This can ensure the friction between the cleaning wheel 16 and the inner wall of the grouting pipe 4, which plays a role in cleaning debris. As the cleaning progresses, more and more debris adheres to the cleaning wheel 16, and the friction force between the cleaning wheel 16 and the inner wall of the grouting pipe 4 becomes greater and greater, which will automatically drive the cleaning wheel 16 to rotate, and then the debris on the cleaning wheel 16 is blown away by the nozzle 17. After being cleaned by the cleaning wheel 16, the inner wall of the grouting pipe 4 is smoother, which is convenient for subsequent fine grinding operations.

[0070] The vertical mechanism includes a plurality of rotating rods 19 rotatably mounted on a fixing frame 1 7 and a fixing frame 2 8. A balance rod 32 is rotatably mounted on the side of each rotating rod 19 away from the corresponding fixing frame 1 7 and the fixing frame 2 8. Each balance rod 32 is rotatably connected to the corresponding rotating block 33. A shaft body is rotatably mounted on each balance rod 32. A disc 38 is rotatably mounted on each shaft body. Each disc 38 is rotatably connected to the corresponding fine grinding wheel 14, fine grinding wheel 2 15, cleaning wheel 16, primary grinding wheel 11, primary grinding wheel 2 12 and pressure control disc 13 through a bearing 39.

[0071] The rotating rod 19 is rotatably connected to the fixing frame 1 7 and the fixing frame 2 8 through an axis, and the rotating rod 1 9 and the rotating rod 2 10 are rotatably connected to the corresponding fixing frame 2 8 and the fixing frame 1 7 through an axis. The spacing between each axis and the corresponding axis is equal to the length of the balance rod 32. In this way, the connecting line between the axis and the axis, the rotating rod 1 9 (rotating rod 2 10), the balance rod 32 and the rotating rod 19 can be regarded as a parallelogram (such as Fig.10 As shown in the figure, with the rotation of rotating rod 19 (rotating rod 2 10), the rotating rod 19 will be driven to rotate. Since the positions of the shaft and the corresponding shaft remain unchanged, the position and angle of one of the short sides of the parallelogram remain unchanged. Therefore, the angle of the balance bar 32 will not change, and the position will change with the movement of rotating rod 19 and rotating rod 19 (rotating rod 2 10). In this way, the balance bar 32 can be ensured to remain in a vertical state, thereby ensuring that the grinding wheel is vertical, avoiding the adjustment of fine grinding wheel 14, fine grinding wheel 2 15, cleaning wheel 16, primary grinding wheel 11, primary grinding wheel 2 12 and pressure control plate 13 from tilting, ensuring the contact area between the fine grinding wheel 14, fine grinding wheel 2 15, cleaning wheel 16, primary grinding wheel 11, primary grinding wheel 2 12 and pressure control plate 13 and the inner wall of the grouting pipe 4, thereby improving the grinding efficiency.

[0072] The multiple rotating rods 10 are divided into a first rotating rod 2, a second rotating rod 2 and a third rotating rod 2, and the multiple rotating rods 1 9 are divided into a first rotating rod 1, a second rotating rod 1 and a third rotating rod 1, which is used to facilitate the distinction between different rotating rods 1 9 and rotating rods 2 10, facilitate subsequent writing, and distinguish the position of the grinding wheel.

[0073] A fine grinding wheel 14 is mounted on the first rotating rod, a fine grinding wheel 2 15 is mounted on the second rotating rod, a cleaning wheel 16 is mounted on the third rotating rod, a primary grinding wheel 11 is mounted on the first rotating rod 2, a primary grinding wheel 2 12 is mounted on the second rotating rod, and a pressure control disk 13 is mounted on the third rotating rod.

[0074] In a further embodiment, referring to Figure 8 , Figure 14-16 A pressure control component that matches the grouting pipe 4 is installed on the pressure control disk 13. The pressure control component includes a receiving groove opened on the pressure control disk 13. A movable frame 41 is slidably installed in the receiving groove. A pressure wheel 40 is rotatably installed on the movable frame 41. A pressure sensor 42 that matches the movable frame 41 is fixedly installed in the receiving groove. The pressure sensor 42 is connected to the dual-axis motor 26 through a controller. The outer surface of the pressure wheel 40 is higher than the outer surface of the pressure control disk 13.

[0075] When the pressing wheel 40 is pressed against the inner wall of the grouting pipe 4, the pressing force between the pressing wheel 40 and the inner wall of the grouting pipe 4 is transmitted to the pressure sensor 42 through the movable frame 41, and then the pressure signal is converted into an electrical signal and transmitted to the controller through the pressure sensor 42. The controller controls the operation of the dual-axis motor 26 to adjust the angles of the rotating rod 1 9 and the rotating rod 2 10, thereby changing the pressing force between the grinding wheel and the inner wall of the grouting pipe 4, achieving constant pressure grinding, and improving the grinding quality. The pressing wheel 40 is rotatably connected to the movable frame 41, so that the pressing wheel 40 can be driven to rotate by friction when the pressure control disk 13 revolves. Since the rotational friction is less than the sliding friction, the friction between the pressing wheel 40 and the inner wall of the grouting pipe 4 is small and can be ignored, thereby protecting the inner wall of the grouting pipe 4 and preventing the inner wall of the grouting pipe 4 from being scratched.

[0076] The specific operation steps of this device are as follows:

[0077] First, place the grouting pipe 4 on the bracket 1, then adjust the height of the grouting pipe 4 so that the central axis of the grouting pipe 4 and the central axis of the end stop plate 25 are at the same horizontal height, and then rotate the screw to make the abutment plate abut against the grouting pipe 4 to lock the grouting pipe 4;

[0078] After locking is completed, the fine grinding wheel 14, the fine grinding wheel 2 15, the cleaning wheel 16, the primary grinding wheel 11, the primary grinding wheel 2 12 and the pressure control plate 13 are inserted into the grouting pipe 4 through the hydraulic rod 3, and then the double-axis motor 26 is started. The two driving ends of the double-axis motor 26 rotate to drive the two screw rods 27 to rotate. The rotation of the screw rod 27 will cause the threaded sleeve 29 to move on the screw rod 27, thereby driving the sliding frame 28 to move with the threaded sleeve 29. With the movement of the sliding frame 28, the connecting rod 30 will be driven to move, thereby driving the rotating rod 1 9 and the rotating rod 2 10 to rotate around the corresponding fixed frame 1 7 and the fixed frame 2 8 through the connecting rod 30, so as to adjust the rotating rod 1 9 to and the angle of the rotating rod 10. The angle adjustment of the rotating rod 19 and the rotating rod 10 will synchronously adjust the positions of the fine grinding wheel 14, the fine grinding wheel 15, the cleaning wheel 16, the primary grinding wheel 11, the primary grinding wheel 12 and the pressure control plate 13, so that the fine grinding wheel 14, the fine grinding wheel 15, the cleaning wheel 16, the primary grinding wheel 11 and the primary grinding wheel 12 are all against the inner wall of the grouting pipe 4, and then the fine grinding wheel 14, the fine grinding wheel 15, the cleaning wheel 16, the primary grinding wheel 11, the primary grinding wheel 12 and the pressure control plate 13 are pulled out of the grouting pipe 4, so that the primary grinding wheel 11, the primary grinding wheel 12 and the pressure control plate 13 are moved to the port position of the grouting pipe 4;

[0079] Then, by turning on the driving motor 22, the driving end of the driving motor 22 rotates to drive the rotating plate 24 to rotate, thereby driving the end limit plate 25 to rotate, thereby driving the fine grinding wheel 14, the fine grinding wheel 2 15, the cleaning wheel 16, the primary grinding wheel 11, the primary grinding wheel 2 12 and the pressure control plate 13 to make a circular motion around the center line of the end limit plate 25, thereby performing turnover grinding;

[0080] At the same time, by turning on the servo motor 18, the driving end of the servo motor 18 rotates and drives, and the rotation of the driving end of the servo motor 18 drives the elastic telescopic rod 1 35 to rotate, thereby driving the elastic telescopic rod 2 37 to rotate through the universal coupling 36, thereby driving the corresponding rotating shaft to rotate, thereby driving the grinding wheel to rotate for self-rotation grinding (because the grinding wheel will rotate around the rotating block 33, the distance between the rotating shaft and the servo motor 18 will change, at this time, the elastic telescopic rod 1 35 and the elastic telescopic rod 2 37 are extended and shortened to compensate for the changed distance), the fine grinding wheel 14 rotates in the opposite direction to the fine grinding wheel 2 15, and the primary grinding wheel 2 12 rotates in the opposite direction to the primary grinding wheel 1 11, thereby improving the grinding efficiency, and cooperating with the cleaning wheel 16 to clean the inner wall after grinding;

[0081] A jet tube 6 is fixedly mounted on the plurality of support rods 31, and a plurality of nozzles 17 are fixedly mounted on the jet tube 6. The jet tube 6 and the nozzles 17 are used to perform jet cleaning from the middle to both sides to clean the grinding debris to prevent the debris from affecting the grinding.

[0082] As the grinding progresses, there will be an error in the thickness of the inner wall of the grouting pipe 4. At this time, the movable frame 41 can transmit the pressing force between the pressing wheel 40 and the inner wall of the grouting pipe 4 to the pressure sensor 42, and then the pressure signal is converted into an electrical signal through the pressure sensor 42 and transmitted to the controller. The controller controls the operation of the dual-axis motor 26 to adjust the angles of the rotating rod 1 9 and the rotating rod 2 10, thereby changing the pressing force between the grinding wheel and the inner wall of the grouting pipe 4 to achieve constant pressure.

[0083] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
