Description

Technical Field

[0001] The invention belongs to the technical field of grinding processing, and in particular relates to a grinding processing device and method for a steel template with a hole. Background Art

[0002] Prefabricated pier technology is a key process in bridge construction. Due to its high quality and precision, short construction cycles, and environmentally friendly, low-impact design, it is widely used in the construction of various sea-crossing bridges. During pier prefabrication, workers first tie the steel cage according to pre-set standards and install it in a specially designed large steel formwork. Concrete is then poured. After strict temperature control, vibration, and curing, the resulting pier prefabricated components are reliable and precise.

[0003] In addition, other forms of steel formwork are required during the pier prefabrication process. For example, steel bar reserved holes need to be set on the steel formwork used for the post-pouring holes of the pier. During the pouring process, the steel bar reserved holes need to be filled with fillers, and then the fillers and steel formwork are removed after the pouring is completed. However, since the contact between concrete and fillers cannot be avoided during concrete pouring, the concrete is easy to adhere to the fillers, thereby blocking the steel bar reserved holes on the steel formwork or leaving a lot of concrete around the open ends of the steel bar reserved holes. The steel formwork needs to be reused during the pier prefabrication process. Therefore, in order to ensure good pouring quality of subsequent pier prefabricated parts, the staff needs to grind the steel formwork before reusing it to remove the attachments on the surface of the steel formwork.

[0004] In existing technology, grinding holes in steel formwork primarily relies on handheld equipment (such as angle grinders). However, because concrete may remain not only at the edges of the steel formwork openings but also within the holes, grinding is difficult. Incomplete grinding can lead to defects in the subsequent prefabricated piers. Consequently, operators often need to use multiple tools repeatedly during the grinding process, which not only affects the efficiency of steel formwork processing but also depends entirely on the operator's skill. This makes the quality of the grinding difficult to guarantee and hinders the reuse of steel formwork. Summary of the Invention

[0005] In view of this, the present invention aims to provide a device and method for grinding and processing perforated steel templates to solve the problem of poor grinding efficiency of hole residues on existing perforated steel templates.

It is rotatably installed on the lifting rod, and a counterweight grinding head is provided at the other end. When the lifting rod is lowered to drive the grinding assembly into the hole of the steel template, the attachments at the hole opening push the grinding piece to rotate upward, so that the grinding assembly can pass over the attachments and extend into the hole. After the grinding assembly is extended into the hole, the lifting rod is rotated to drive the grinding piece to rotate horizontally, so that the counterweight grinding head moves away from the lifting rod under the action of centrifugal force and presses against the inner wall of the hole. The end of the lifting sleeve extending into the hole limits the outer diameter of the grinding assembly by pressing against the grinding piece.

[0007] Furthermore, the rotating seat is provided with a guide hole for guiding the grinding assembly into the receiving groove.

[0015] In a second aspect, the present invention further provides a method for grinding a perforated steel template, which is implemented using the above-mentioned perforated steel template grinding device and specifically comprises the following steps: Step S1, obtaining the position of the hole on the perforated steel template and the position of the perforated steel template grinding processing device, and controlling the perforated steel template grinding processing device to move toward the center of the hole; Step S2: When the perforated steel template grinding device moves toward the center of the hole, the power assembly on the grinding module drives the rotating seat to rotate, and the grinding disc on the rotating seat is used to grind the attachments on the surface of the perforated steel template; Step S3: After the lifting rod on the perforated steel template grinding processing device moves to the center of the hole, the perforated steel template grinding processing device is controlled to move so that the lifting rod can move in a circle with the center of the hole as the center and a preset length as the radius, and during the movement, the lifting rod is driven to rise and fall by the second drive assembly to perform grinding processing; wherein the preset length is less than the difference between the hole radius and the cross-sectional radius of the lifting rod; Step S4: Control the perforated steel template grinding processing device to move and reset. When the lifting rod on the grinding module moves back to the center of the hole, the lifting rod is driven down by the second driving assembly so that the grinding assembly extends into the hole. Step S5: Using the first driving assembly to drive the lifting sleeve downward, and after the lifting sleeve supports the polishing member to limit the outer diameter of the polishing assembly, the polishing assembly is used to polish the attachments on the inner wall of the hole; Step S6: Using the second drive assembly to drive the lifting rod to rise, and using the first drive assembly to drive the lifting sleeve to rise synchronously with the lifting rod, so as to ensure that the outer diameter of the grinding assembly remains unchanged when grinding the attachment on the inner wall of the hole; Step S7: After the grinding assembly on the lifting rod moves out of the hole and enters the rotating seat receiving groove to complete storage, the first driving assembly and the second driving assembly are stopped; Step S8, repeating steps S1 to S7 until all holes on the perforated steel template are polished.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0020] A perforated steel template grinding device is used to grind the perforated steel template used for prefabricated piers, thereby removing concrete and other attachments attached to the hole positions on the steel template, ensuring that the hole positions of the perforated steel template meet surface accuracy and size requirements during subsequent cyclic use.

[0021] Specifically, the perforated steel template grinding and processing device in this embodiment includes a carrying plate and a wall-climbing robot. The carrying plate is detachably arranged on the wall-climbing robot. A liftable equipment mounting frame is provided on the carrying plate. A detachable grinding module is provided on the equipment mounting frame. A driving mechanism for driving the equipment mounting frame to rise and fall is provided on the carrying plate.

[0022] like Figure 1 As shown, the supporting plate 2 can be detachably mounted and fixed on the wall-climbing robot 1 by conventional means such as screws, and a guide rail for mounting the supporting plate 2 can be fixed on the wall-climbing robot 1, so that the operator can adjust the position of the supporting plate 2 on the wall-climbing robot 1 according to actual needs, so that the grinding module 5 on the equipment mounting frame 3 can better grind the perforated steel template.

[0023] In addition, the grinding module 5 can be installed on the equipment mounting frame 3 by conventional means such as screws. One end of the equipment mounting frame 3 can be rotatably installed on the supporting plate 2 by conventional means such as a connecting arm, and the grinding module 5 is installed on the other end. The driving mechanism 4 can adopt a conventional driving mechanism 4 such as a hydraulic cylinder. One end of the hydraulic cylinder is rotatably installed on the supporting plate, and the other end is rotatably installed with the equipment mounting frame 3 to realize the lifting and lowering of the grinding module 5 on the equipment mounting frame 3, and then drive the grinding module 5 to contact the perforated steel template to realize grinding. Technical personnel in this field can also choose other suitable equipment mounting frame 3 installation methods according to actual needs, and adopt corresponding driving mechanism 4 to realize the lifting and lowering of the driving equipment mounting frame 3 to ensure that the grinding module 5 can realize the grinding of the perforated steel template. This is not the main innovation of the present device, so it will not be repeated here.

[0024] In actual use, the wall-climbing robot 1 drives the grinding module 5 to move along a preset path on the perforated steel template, and uses the grinding module 5 to automatically grind the holes in the perforated steel template, which is beneficial to improving the grinding efficiency and treatment effect of the perforated steel template. It should be noted that the wall-climbing robot 1 described in this embodiment is a mature automated mobile operation equipment in the prior art, and the working principle, specific structure, and control method of the wall-climbing robot 1 are all well known to the public.

[0025] like Figures 2 to 8 As shown, the polishing module 5 in this embodiment includes: The rotating seat 6 is rotatably mounted on the polishing module 5 . A detachable polishing disc 7 is provided on the rotating seat 6 . The polishing module 5 is provided with a power assembly 8 for driving the rotating seat 6 to rotate.

[0026] The lifting sleeve 10 is coaxially arranged with the rotating seat 6. The lifting sleeve 10 is vertically slidably installed on the rotating seat 6, and the lifting sleeve 10 can be driven to rotate by the rotation of the rotating seat 6. The polishing module 5 is provided with a first driving component for driving the lifting sleeve 10 to lift and lower.

[0027] The lifting rod 11 is coaxially arranged with the lifting sleeve 10. The lifting rod 11 is vertically slidably mounted on the lifting sleeve 10, and the lifting rod 11 can be driven to rotate by the rotation of the lifting sleeve 10. The grinding module 5 is provided with a second driving component for driving the lifting rod 11 to rise and fall; the lifting rod 11 is provided with a detachable grinding component at one end facing the grinding disc 7, and the other end passes through the lifting sleeve 10. The rotating seat 6 is provided with a receiving groove 18 for accommodating the grinding component; the grinding component includes a grinding piece 16, and the grinding piece 16 is at least evenly arranged along the circumference of the lifting rod 11. The grinding piece 16 is rotatably mounted on the lifting rod 11 at one end, and a counterweight grinding head 17 is provided at the other end. When the lifting rod 11 is lowered to drive the grinding assembly into the hole of the steel template, the attachments at the hole opening push the grinding piece 16 to rotate upward, so that the grinding assembly can pass over the attachments and extend into the hole. After the grinding assembly is extended into the hole, the lifting rod 11 is rotated to drive the grinding piece 16 to rotate horizontally, so that the counterweight grinding head 17 is moved away from the lifting rod 11 under the action of centrifugal force and presses against the inner wall of the hole. The end of the lifting sleeve 10 extending into the hole limits the outer diameter of the grinding assembly by pressing against the grinding piece 16.

[0028] Optionally, the grinding module 5 includes a shell, and the rotating seat 6 can be rotatably mounted on the shell by conventional means such as bearings. The power assembly 8 includes a driving motor mounted on the shell, and the end of the driving motor extending into the shell is provided with a driving wheel, and the end of the rotating seat 6 extending into the shell is provided with a driven wheel that can cooperate with the driving wheel. The shell is also provided with a transmission mechanism for realizing the cooperation between the driving wheel and the driven wheel, such as gears or belts. Those skilled in the art can also choose other methods to install the rotating seat 6 according to actual needs, and use the corresponding power assembly 8 to realize the driving rotation of the rotating seat 6. It will not be repeated here.

[0029] In actual application, the grinding disc 7 can be detachably mounted on the rotating base 6 by conventional means such as screws. When the grinding module 5 is used to grind the perforated steel template, the power assembly 8 can be started to drive the rotating base 6 to rotate, and the rotating base 6 is continuously rotated to drive the grinding disc 7 to grind the surface of the perforated steel template.

[0030] Optionally, the lifting sleeve 10 and the rotating seat 6, as well as the lifting rod 11 and the lifting sleeve 10 can be slidably connected by conventional means such as spline connection, while ensuring that the rotating seat 6 can drive the lifting sleeve 10 and the lifting rod 11 to rotate. Those skilled in the art can also choose other methods according to actual needs, which will not be repeated here.

[0031] In actual application, the lifting rod 11 can be used to extend and drive the grinding assembly into the hole on the perforated steel template. During the process of the grinding assembly extending into the hole, the grinding piece 16 will first contact the concrete at the hole opening and rotate upward under the push of the concrete at the hole opening to reduce the outer diameter of the grinding assembly as a whole, so that the grinding assembly can pass over the concrete at the hole opening and extend into the area in the hole where there is no concrete attached. After that, the rotation of the lifting rod 11 can generate centrifugal force. Under the action of centrifugal force, the counterweight grinding head 17 moves in the direction away from the lifting rod 11 and drives the grinding piece 16 to rotate until the counterweight grinding head 17 hits the inner wall of the hole where there is no concrete attached. At this time, the horizontal rotation of the grinding piece 16 is restricted by the inner wall of the hole, and the outer diameter of the grinding assembly as a whole is the same as the normal hole diameter. Finally, the lifting sleeve 10 is lowered and extended into the hole. The lower end of the lifting sleeve 10 can limit the vertical rotation of the grinding piece 16 by pressing against the upper surface of the grinding piece 16, thereby limiting the outer diameter of the entire grinding assembly, ensuring that during the grinding process, the outer diameter of the grinding assembly is always consistent with the normal aperture of the hole.

[0032] In addition, during the grinding process, the lifting sleeve 10 can be continuously used to support the upper surface of the grinding piece 16 to achieve positioning, and the lifting sleeve 10 can be lifted and lowered by the lifting rod 11 to further achieve effective grinding of the concrete attached to the inner wall of the hole, which is beneficial to improving the grinding effect.

[0033] Preferably, the rotating base 6 is provided with a guide hole 19 for guiding the grinding assembly into the receiving groove 18. The guide hole 19 is a trumpet-shaped structure, with the small opening end of the guide hole 19 communicating with the receiving groove 18 and the large opening end facing the grinding assembly. Specifically, the grinding disc 7 can be positioned corresponding to the edge of the receiving groove 18 to prevent interference between the grinding disc 7 and the grinding assembly, while also ensuring that the grinding disc 7 effectively grinds the surface of the perforated steel template.

[0034] In actual application, the lifting rod 11 drives the lifting sleeve 10 to rotate through the rotating seat 6, so there is no relative rotation between the lifting rod 11 and the rotating seat 6. When the grinding assembly on the lifting rod 11 completes the grinding of the holes in the perforated steel template, the lifting rod 11 and the lifting sleeve 10 can be driven to rise. As the lifting rod 11 rises, the counterweight grinding head 17 on the grinding piece 16 will first contact the inner wall of the guide hole 19 and move along the inclined surface of the inner wall of the guide hole 19, thereby driving the grinding piece 16 to perform reset rotation in the vertical and horizontal directions, so as to realize the gradual reduction of the outer diameter of the grinding assembly. Until the grinding assembly is moved back into the receiving groove 18 to complete the storage, the lifting rod 11 and the lifting sleeve 10 can stop lifting.

[0035] By providing a receiving groove 18 for accommodating the grinding assembly on the rotating seat 6, the receiving groove 18 can provide good protection for the grinding assembly. At the same time, when the grinding disc 7 is grinding the surface of the perforated steel template, the grinding assembly will not affect the movement of the grinding module 5, so that the wall-climbing robot 1 can grind the perforated steel template along a preset route. At the same time, by providing a trumpet-shaped guide hole 19, it can play a good guiding role for the grinding assembly. After the hole grinding is completed, the grinding assembly is guided into the receiving groove 18 for storage, which facilitates the grinding module 5 to carry out subsequent grinding operations on the perforated steel template or the inner wall of the hole, which is conducive to improving the grinding efficiency of this device.

[0036] Preferably, the counterweight grinding head 17 is rotatably mounted on the grinding piece 16, and the rotation direction of the counterweight grinding head 17 is vertical. Specifically, the counterweight grinding head 17 can adopt conventional grinding heads such as grinding wheels and grinding balls, and is rotatably mounted on the grinding piece 16 by conventional means such as a rotating shaft. The grinding piece 16 is provided with a mounting groove for mounting the counterweight grinding head 17. Those skilled in the art can also select a suitable counterweight grinding head 17 and its rotational mounting method according to actual needs. It should be noted that the mass of the counterweight grinding head 17 can be set according to actual needs. Preferably, the mass is greater than the grinding piece 16, so that the counterweight grinding head 17 can generate sufficient centrifugal force when the lifting rod 11 rotates, thereby driving the grinding piece 16 to achieve horizontal rotation and realize the change of the overall outer diameter of the grinding assembly.

[0037] In actual application, by rotating the counterweight grinding head 17 on the grinding member 16, when the lifting rod 11 rises, rolling friction occurs between the counterweight grinding head 17 and the inner wall of the guide hole 19, so that the inner wall of the guide hole 19 can better guide the counterweight grinding head 17, thereby achieving the storage of the grinding assembly in the receiving groove 18. At the same time, when the lifting rod 11 descends and drives the grinding assembly to pass over the remaining concrete in the hole, the counterweight grinding head 17 can also more easily pass over the remaining concrete blocks by rotating, and will not cause obstruction to the grinding assembly. In addition, when the lifting rod 11 drives the grinding assembly to grind the concrete on the inner wall of the hole, when the lifting sleeve 10 limits the outer diameter of the grinding assembly, the counterweight grinding head 17 can be polished closely against the inner wall of the hole, and at this time, it is mainly the side of the counterweight grinding head 17 that plays the grinding role.

[0038] Preferably, the grinding member 16 is rotatably mounted on the lifting rod 11 via a universal joint 22. A stopper 21 is provided on the lifting rod 11 at a position corresponding to the bottom of the grinding member 16, for limiting the downward rotation of the grinding member 16. Specifically, the universal joint 22 can be a conventional universal joint, such as a ball joint. One end of the universal joint 22 can be mounted on the grinding member 16 via a conventional method, such as a screw, and the other end can be threadedly connected to the lifting rod 11 to achieve removable assembly. Those skilled in the art can also select other suitable universal joints 22 and corresponding mounting methods according to actual needs to achieve rotation and removable assembly of the grinding member 16 on the lifting rod 11, and this will not be described in detail here.

[0039] In actual application, the limiting portion 21 can play a good limiting role on the grinding piece 16, limiting the downward rotation of the grinding piece 16, which is not only beneficial to improving the stability of the grinding piece 16 on the lifting rod 11, and ensuring the strength of the grinding piece 16 during the grinding process; and the limiting portion 21 can play a good structural reinforcement role on the connection between the grinding piece 16 and the lifting rod 11, ensuring that when the counterweight grinding head 17 contacts the inner wall of the hole, the grinding piece 16 can remain stable on the lifting rod 11, thereby improving the stability of the grinding assembly during the grinding process, so that the outer diameter of the grinding assembly remains unchanged when it rises with the lifting rod 11 to grind the inner wall of the hole, which is beneficial to improving the grinding accuracy of the holes in the perforated steel template, and even the requirements can be met with one grinding process, and the grinding efficiency is also higher.

[0040] Preferably, a detachable drill bit 20 is provided on the lifting rod 11 at a position corresponding to the position below the grinding member 16. For example, the drill bit 20 can be a conventional drill bit and fixed to the lifting rod 11 by conventional means such as screws. Those skilled in the art can also select a suitable drill bit and its corresponding mounting method according to actual needs to achieve detachable assembly of the drill bit 20 on the lifting rod 11.

[0041] In actual application, by arranging a drill bit 20 on the lifting rod 11, when the lifting rod 11 is extended into the hole of the perforated steel template, the drill bit 20 can be used to grind the concrete that blocks the hole, so that the grinding component can be subsequently extended into the hole for grinding. This grinding component can not only grind the surrounding surface and inner wall of the hole of the perforated steel template, but also grind the hole blocked by concrete, thereby improving the applicability of this device to different grinding processing requirements.

[0042] Preferably, the grinding member 16 is a curved rod-shaped structure. Specifically, the outer curved surface of the grinding member 16 serves as the working surface in contact with the concrete. Compared with grinding members 16 of other structures, the grinding member 16 of the curved rod structure not only meets the requirements of rotation, opening, and storage, but also has a higher structural strength and a better grinding effect on the concrete.

[0043] In actual application, a cutting portion 23 is provided on one side of the grinding piece 16. For example, the cutting portion 23 is provided with a conical surface or an inclined surface, and is arranged on one side of the outer arc surface of the grinding piece 16 to improve the grinding effect of the grinding piece 16 on the concrete. In addition, after the drill bit 20 is used to complete the drilling of the concrete that blocks the hole, the lifting rod 11 can also be used to drive the grinding assembly to extend into the hole. During the process of the grinding assembly drilling deep into the hole, the cutting portion 23 on one side of the grinding piece 16 can also grind the concrete, thereby expanding the hole diameter, so that the grinding assembly can more smoothly pass through the hole and extend into the hole. Similarly, when the drill bit 20 is not used for drilling, the cutting portion 23 on the grinding piece 16 can also grind the concrete at the end of the hole to expand the hole diameter, so that the grinding assembly can extend into the hole more smoothly.

[0044] Preferably, a protective cover 9 is provided on the polishing module 5, and the first and second drive assemblies are both disposed within the protective cover 9. Specifically, the protective cover 9 can be removably mounted to the polishing module housing using conventional means such as screws. In actual use, the protective cover 9 effectively protects the rotating base 6, the lifting sleeve 10, the lifting rod 11, the first and second drive assemblies, preventing dust flying during the polishing process from affecting the operation of these components, thereby improving the reliability of the device during use.

[0045] Optionally, the first drive component includes a first telescopic cylinder 12, at least two of the first telescopic cylinders 12 are evenly arranged along the circumference of the lifting sleeve 10, a first connecting seat 13 is provided on the lifting sleeve 10, the first connecting seat 13 is rotatably mounted on the lifting sleeve 10, the fixed end of the first telescopic cylinder 12 is set on the protective cover 9, and the telescopic end is connected to the first connecting seat 13; the second drive component includes a second telescopic cylinder 14, at least two of the second telescopic cylinders 14 are evenly arranged along the circumference of the lifting rod 11, a second connecting seat 15 is provided on the lifting rod 11, the second connecting seat 15 is rotatably mounted on the lifting rod 11, the fixed end of the second telescopic cylinder 14 is set on the protective cover 9, and the telescopic end is connected to the second connecting seat 15.

[0046] Alternatively, those skilled in the art may also select other methods to install the first telescopic cylinder 12 and the second telescopic cylinder 14 according to actual needs. For example, the fixed ends of the first telescopic cylinder 12 and the second telescopic cylinder 14 may be mounted on an assembly rack (not shown) using screws or other conventional means, and then the assembly rack may be connected to the protective cover 9 using screws or other conventional means. Finally, the protective cover 9 may be fixed to the housing of the polishing module 5 using screws or other conventional means, so that the protective cover 9 covers the first telescopic cylinder 12 and the second telescopic cylinder 14. In addition, those skilled in the art may select other suitable mounting methods according to actual needs to achieve stable assembly of the first telescopic cylinder 12 and the second telescopic cylinder 14, and no further details will be given here.

[0047] In actual application, two of each of the first telescopic cylinder 12 and the second telescopic cylinder 14 are provided. Those skilled in the art may also provide multiple ones according to actual needs, which will not be elaborated here. Among them, the fixed end of the first telescopic cylinder 12 can be mounted on the protective cover 9 by conventional means such as screws, and the telescopic end can be rotatably mounted on the first connecting seat 13 by conventional means such as screws, and the first connecting seat 13 can be rotatably mounted on the lifting sleeve 10 by conventional means such as bearings. The second telescopic cylinder 14 and the second connecting seat 15 are similar. Those skilled in the art may select a suitable method to install the first telescopic cylinder 12 and the second telescopic cylinder 14 according to actual needs, and select a suitable method to install the first connecting seat 13 and the second connecting seat 15, so as to realize the use of the first telescopic cylinder 12 to drive the lifting sleeve 10 to rise and fall, and the second telescopic cylinder 14 to drive the lifting rod 11 to rise and fall, and at the same time, the lifting sleeve 10 and the lifting rod 11 can also rotate with the rotating seat 6, which will not be elaborated here.

[0048] In addition, in order to ensure the stability of the lifting rod 11 and the lifting sleeve 10, the first connecting seat 13 and the second connecting seat 15 can also be slidably installed on the protective shell through guide rails or guide rods, or two first telescopic cylinders 12 and second telescopic cylinders 14 are correspondingly set. Technical personnel in this field can choose the setting according to actual needs, and will not go into details here.

[0049] Based on the above content, this embodiment also provides a method for grinding and processing perforated steel formwork, which is implemented by the above-mentioned perforated steel formwork grinding and processing device. By using this method for grinding and processing perforated steel formwork, the concrete remaining in the holes on the perforated steel formwork can be effectively ground and cleaned. Not only can the concrete remaining on the edge of the hole of the perforated steel formwork be effectively removed, but also the concrete remaining in the sealed hole and the hole can be effectively removed, so that the grinding process can achieve better quality and higher efficiency.

[0050] Figure 9 This is a flow chart of a method for grinding a perforated steel template according to an embodiment of the present invention. Figure 9 The grinding treatment method of the perforated steel template specifically includes the following steps: Step S1, obtaining the position of the hole on the perforated steel template and the position of the perforated steel template grinding and processing device, and controlling the perforated steel template grinding and processing device to move toward the center of the hole.

[0051] Before performing the grinding process, the position of the holes on the perforated steel template can be measured or obtained. In this embodiment, the position of the perforated steel template grinding device is used as the starting point, and the position of the holes on the perforated steel template is used as the end point to determine the operating direction and route of the perforated steel template grinding device. It should be noted that when actually measuring or obtaining the position of the holes on the perforated steel template, it is also necessary to measure or obtain the initial size of the holes to ensure that the outer diameter of the grinding component after it is inserted into the hole is not greater than the initial size of the hole, thereby preventing damage to the grinding component or the inner wall of the hole.

[0052] Specifically, the maximum descent height of the lifting sleeve can be tested or measured before actual use. By controlling the descent height of the lifting sleeve, the lifting sleeve can be used to press against the upper surface of the grinding piece to limit the outer diameter of the grinding component, so that the outer diameter of the grinding component can match the initial size of the hole, thereby avoiding compression and bending of the grinding piece or damage to the inner wall of the hole due to excessive descent of the lifting sleeve.

[0053] Step S2: When the perforated steel template grinding processing device moves toward the center of the hole, the power assembly on the grinding module is used to drive the rotating seat to rotate, and the grinding disc on the rotating seat is used to grind the attachments on the surface of the perforated steel template.

[0054] Since concrete is easily retained on the surface of the perforated steel formwork, especially in the holes, in order to subsequently clean the concrete in the holes, the concrete on the surface of the perforated steel formwork needs to be polished first to loosen and shape the residual concrete in the holes.

[0055] In actual application, the power component on the grinding module is used to drive the rotating seat to rotate, and the wall-climbing robot is used to drive the grinding module to move. The grinding disc can grind from one side of the hole edge to the other side. During the grinding process, the grinding disc can also play a mobile role in crushing and loosening the concrete at the hole, which is conducive to the initial separation of the concrete from the inner wall of the hole. There is also a certain probability that the concrete blocking the hole and the concrete in the hole will fall off, which is conducive to reducing the difficulty of subsequent grinding of the residual concrete on the inner wall of the hole.

[0056] Step S3: After the lifting rod on the perforated steel template grinding processing device moves to the center of the hole, the perforated steel template grinding processing device is controlled to move so that the lifting rod can move in a circle with the center of the hole as the center and a preset length as the radius, and during the movement, the second drive component is used to drive the lifting rod to rise and fall for grinding processing; wherein, the preset length is less than the difference between the hole radius and the cross-sectional radius of the lifting rod.

[0057] Since the concrete used to seal the hole may be quite thick, grinding with a grinding disc alone may not be enough to form a hole in the concrete surface, which in turn prevents the lifting rod and the grinding assembly on the lifting rod from directly extending into the hole. Therefore, during the actual grinding process, after the lifting rod moves to the center of the hole, it can also drive the perforated steel template grinding device to move, so that the lifting rod can move in a circular motion with the center of the hole as the center and a preset length as the radius, grinding the concrete surface that seals the hole, grinding annular grooves or multiple through holes in the concrete surface, further breaking and loosening the concrete, and forming a through hole on the concrete surface through which the lifting rod and the grinding assembly can pass.

[0058] It should be noted that the preset length should be smaller than the difference between the hole radius and the cross-sectional radius of the lifting rod, so as to prevent the lifting rod from interfering with the edge of the hole when the lifting rod is grinding in a circular motion, and ensure that the lifting rod only grinds the concrete that blocks the hole.

[0059] During actual application, the lifting rod can be driven to rise and fall repeatedly while moving in a circular motion with the wall-climbing robot, so that the drill bit on the lifting rod can contact the concrete that seals the hole, perform efficient grinding on the concrete surface, and quickly form a through hole or annular groove on the concrete surface.

[0060] Step S4, controlling the perforated steel template grinding processing device to move and reset, when the lifting rod on the grinding module moves back to the center of the hole, using the second driving assembly to drive the lifting rod down, so that the grinding assembly extends into the hole.

[0061] After the circular movement of the lifting rod in the above steps, the concrete blocking the middle of the hole has broken down or its bond with the concrete at the edge of the hole has weakened. At this time, the lifting rod can be moved downward to quickly push open the concrete in the middle of the hole, allowing the lifting rod and grinding assembly to extend into the hole. At the same time, as the lifting rod rotates, the grinding assembly can also adjust its outer diameter under the action of centrifugal force, and ultimately make the counterweight grinding head press against the inner wall of the hole.

[0062] Step S5: Use the first driving assembly to drive the lifting sleeve to descend, and after the lifting sleeve supports the grinding piece to limit the outer diameter of the grinding assembly, use the grinding assembly to grind the attachments on the inner wall of the hole.

[0063] When the grinding assembly on the lifting rod passes over the concrete on the inner wall of the hole and the counterweight grinding head contacts the inner wall of the hole, the first driving assembly can be used to drive the lifting sleeve to descend, and the lifting sleeve is used to support the upper surface of the grinding piece to achieve the limitation of the grinding piece. At this time, the counterweight grinding head can support the inner wall of the hole, and the grinding assembly can form a claw-like structure in the hole, ensuring that the counterweight grinding head can continuously and stably grind the concrete on the inner wall of the hole.

[0064] Step S6: Use the second drive assembly to drive the lifting rod to rise, and use the first drive assembly to drive the lifting sleeve to rise synchronously with the lifting rod to ensure that the outer diameter of the grinding assembly remains unchanged when grinding the attachments on the inner wall of the hole.

[0065] As the lifting rod and sleeve rise synchronously, the claw-like grinding assembly gradually grinds the concrete on the inner wall of the hole from bottom to top. When the counterweight grinding head is blocked by a concrete block, not only does it continue grinding the block, but as the lifting rod rises, the claw-like grinding assembly also loosens the block, accelerating the separation of the concrete from the inner wall of the hole, further improving grinding efficiency. Furthermore, by synchronously rising the lifting rod and sleeve, the outer diameter of the grinding assembly remains unchanged due to the limiting action of the sleeve, ensuring the grinding quality of the inner wall of the hole and avoiding damage to the hole surface.

[0066] Step S7: When the grinding assembly on the lifting rod moves out of the hole and enters the rotating seat receiving groove to complete storage, the first driving assembly and the second driving assembly are stopped.

[0067] Once the grinding assembly on the lifting rod is removed from the hole, the entire grinding process for the hole is completed. As the lifting rod continues to rise, guided by the guide hole, the grinding assembly can be stored in the receiving slot. Once the grinding assembly is stored in the receiving slot, the first and second drive assemblies are stopped, completing the grinding process for the hole.

[0068] Step S8, repeating steps S1 to S7 until all holes on the perforated steel template are polished.

[0069] Since there are generally multiple holes on the perforated steel template, the above steps S1 to S7 are repeated to complete the grinding process of the holes on the perforated steel template one by one, and then the grinding process of the perforated steel template can be completed.

[0070] The following describes the effects of the above scheme: This embodiment provides a device and method for polishing a steel template with holes. By integrating a polishing disc for polishing the surface of the steel template with holes and a polishing assembly for polishing the holes of the steel template with holes on a polishing module, it is possible to effectively clean the residual attachments left after the use of the steel template with holes, and the polishing effect is good, the polishing efficiency is high, and it is not easy to damage the surface quality of the steel template with holes. In addition, by installing a lifting rod with a polishing assembly on a rotating seat through a lifting sleeve, the rotating seat is driven to rotate by a power assembly to achieve synchronous driving of the polishing disc and the polishing assembly, thereby simplifying the overall structure and improving reliability. The lifting sleeve can also limit the outer diameter of the polishing assembly, ensuring that the outer diameter of the polishing assembly remains unchanged when polishing the inner wall of the hole, which is conducive to further improving the polishing quality.
