Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of polishing treatment, and particularly relates to a steel formwork with holes polishing treatment device and method. BACKGROUND

[0002] The prefabricated pier technology is a key process for bridge construction, and is widely used in the construction process of various sea-crossing bridges due to its high quality precision, short construction period and low environmental disturbance. When prefabricating the pier, the staff needs to first bind the reinforcement cage according to the preset standard and load it into a specially designed large steel formwork, and then pour the concrete. After strict temperature control, vibration and maintenance, a pier prefabricated part with reliable quality and excellent precision can be obtained.

[0003] In addition, other forms of steel formwork are also needed in the pier prefabrication process, such as steel formwork for pier post-pouring holes, which need to be provided with steel reinforcement reserved holes. During the pouring process, the steel reinforcement reserved holes need to be filled with fillers first, and then the fillers and steel formwork are removed after pouring is completed. However, due to the inevitable contact between concrete and fillers during concrete pouring, the concrete is easy to adhere to the fillers and block the steel reinforcement reserved holes on the steel formwork or leave a lot of concrete around the opening end of the steel reinforcement reserved holes. Therefore, in order to ensure that the subsequent pier prefabricated part has good pouring quality, the staff needs to polish the steel formwork before reusing it, so as to remove the attachments on the surface of the steel formwork.

[0004] In the prior art, the polishing treatment of the steel formwork hole is mainly completed by the staff holding the processing equipment (such as an angle grinder). However, since the concrete may not only remain on the edge of the opening end of the steel formwork hole, but also remain in the steel formwork hole, the staff has great difficulty in polishing treatment. If the polishing treatment is not thorough, defects may occur on the subsequent pier prefabricated part. Therefore, during the actual polishing process, the operator even needs to use multiple tools to polish repeatedly, which not only affects the processing efficiency of the steel formwork, but also depends entirely on the operation skills of the operator, and the processing quality cannot be guaranteed, which is not conducive to the reuse of the steel formwork.

[0042] The application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the application, and not to limit the application. In addition, it should be noted that, for the sake of description, only the parts related to the application are shown in the drawings, not all the structures.

[0043] A hole steel template polishing device is used for polishing a hole steel template used for a prefabricated pier, so as to remove the adhering objects such as concrete adhered to the hole position of the steel template, and ensure that the hole position of the hole steel template meets the surface precision and size requirements in the subsequent recycling process.

[0045] As Figure 1As shown, the bearing plate 2 can be detachably mounted on the wall climbing robot 1 by conventional means such as screws, and a guide rail for mounting the bearing plate 2 can be fixed on the wall climbing robot 1, so that the operator can adjust the position of the bearing plate 2 on the wall climbing robot 1 according to actual needs, so that the polishing module 5 on the equipment mounting rack 3 can better polish the perforated steel formwork.

[0046] In addition, the polishing module 5 can be mounted on the equipment mounting rack 3 by conventional means such as screws, and the equipment mounting rack 3 can be rotatably mounted on the bearing plate 2 by conventional means such as connecting arms, and the other end is mounted with the polishing module 5, and the driving mechanism 4 can adopt a conventional driving mechanism 4 such as a hydraulic cylinder, and the hydraulic cylinder is rotatably mounted on the bearing plate at one end, and the other end is rotatably mounted with the equipment mounting rack 3, so as to realize driving the polishing module 5 on the equipment mounting rack 3 to ascend and descend, and then drive the polishing module 5 to contact with the perforated steel formwork to realize polishing.

This is not the main innovation point of the device, so it will not be repeated here.

[0047] In actual application process, the wall climbing robot 1 drives the polishing module 5 to move on the perforated steel formwork along the preset travel route, and utilizes the polishing module 5 to automatically polish the holes on the perforated steel formwork, which is beneficial to improve the polishing efficiency and processing effect of the perforated steel formwork. It should be noted that the wall climbing robot 1 described in the embodiment is a mature automatic mobile operation equipment in the prior art, and the working principle, specific structure and control method of the wall climbing robot 1 are well known to the public.

[0048] As shown in the figure, Figures 2 to 8 The polishing module 5 in the embodiment includes:

[0049] The rotating seat 6 is rotatably mounted on the polishing module 5, and the rotating seat 6 is provided with a detachable polishing disc 7, and the polishing module 5 is provided with a power assembly 8 for driving the rotating seat 6 to rotate.

[0050] The lifting sleeve 10 is coaxially arranged with the rotating seat 6, and the lifting sleeve 10 is vertically slidably mounted on the rotating seat 6 and can be rotated by the rotating seat 6 to drive the lifting sleeve 10 to rotate, and the polishing module 5 is provided with a first driving assembly for driving the lifting sleeve 10 to ascend and descend.

[0051] The lifting rod 11 is coaxially arranged with the lifting sleeve 10, is vertically slidingly installed on the lifting sleeve 10, and can be rotated by the lifting sleeve 10 to drive the lifting rod 11 to rotate, and the polishing module 5 is provided with a second driving assembly for driving the lifting rod 11 to lift; one end of the lifting rod 11 towards the polishing disc 7 is provided with a detachable polishing assembly, and the other end penetrates through the lifting sleeve 10; the rotating seat 6 is provided with a containing groove 18 for containing the polishing assembly; the polishing assembly comprises polishing pieces 16, and the polishing pieces 16 are evenly arranged at least two circumferentially along the lifting rod 11, each polishing piece 16 is rotatably installed at one end on the lifting rod 11, and the other end is provided with a counterweight polishing head 17; when the polishing assembly is driven to extend into the hole of the steel formwork by the lifting rod 11, the adhering matter at the opening of the hole pushes the polishing piece 16 to rotate upwards, so that the polishing assembly can pass through the adhering matter and extend into the hole, and after the polishing assembly extends into the hole, the polishing piece 16 is driven to rotate horizontally by the rotation of the lifting rod 11, so that the counterweight polishing head 17 is driven away from the lifting rod 11 under the action of centrifugal force and abuts against the inner wall of the hole, and the one end of the lifting sleeve 10 extending into the hole limits the outer diameter of the polishing assembly by abutting against the polishing piece 16.

[0052] Optionally, the polishing module 5 comprises a shell, the rotating seat 6 is rotatably installed on the shell by a bearing or other conventional means, the power assembly 8 comprises a driving motor installed on the shell, one end of the driving motor extending into the shell is provided with a driving wheel, one end of the rotating seat 6 extending into the shell is provided with a driven wheel capable of cooperating with the driving wheel, and the shell is further provided with a transmission mechanism, such as a gear or a belt, for realizing the cooperation between the driving wheel and the driven wheel, and those skilled in the art can also select other ways to install the rotating seat 6 according to actual needs, and adopt the corresponding power assembly 8 to realize the driving of the rotating seat 6 to rotate, which will not be described here.

[0053] In actual application, the polishing disc 7 can be detachably installed on the rotating seat 6 by screws or other conventional means. When the polishing module 5 is used to polish the hole steel formwork, the power assembly 8 can be started to drive the rotating seat 6 to rotate, and the polishing disc 7 is driven to rotate continuously by the rotating seat 6 to polish the surface of the hole steel formwork.

[0054] Optionally, the lifting sleeve 10 and the rotating seat 6, and the lifting rod 11 and the lifting sleeve 10 can be slidingly connected by spline connection or other conventional means, while ensuring that the rotating seat 6 can drive the lifting sleeve 10 and the lifting rod 11 to rotate, and those skilled in the art can also select other ways according to actual needs, which will not be described here.

[0055] In actual application process, the lifting rod 11 can be used to extend into the hole of the hole steel template to drive the polishing assembly to extend into the hole, in the process of extending the polishing assembly into the hole, the polishing piece 16 will first contact the concrete at the opening of the hole, and will rotate upward under the pushing of the concrete at the opening of the hole, so as to reduce the outer diameter of the polishing assembly as a whole, so that the polishing assembly can pass through the concrete at the opening of the hole and extend into the area without concrete attachment in the hole. Then the rotation of the lifting rod 11 can generate centrifugal force, the counterweight polishing head 17 moves away from the lifting rod 11 under the action of the centrifugal force, and drives the polishing piece 16 to rotate, until the counterweight polishing head 17 abuts against the inner wall of the hole without concrete attachment, at this time the horizontal rotation of the polishing piece 16 is limited by the inner wall of the hole, and the outer diameter of the polishing assembly as a whole is the same as the normal hole diameter. Finally, the lifting sleeve 10 is lowered and extends into the hole, and the lower end of the lifting sleeve 10 can limit the vertical rotation of the polishing piece 16 by abutting against the upper surface of the polishing piece 16, that is, the outer diameter of the polishing assembly as a whole can be limited, so as to ensure that the outer diameter of the polishing assembly is consistent with the normal hole diameter during the polishing process.

[0056] In addition, during the polishing process, the lifting sleeve 10 can be used to limit the polishing piece 16 by abutting against the upper surface of the polishing piece 16, and the lifting rod 11 can be used to further polish the concrete attached to the inner wall of the hole by moving up and down with the lifting sleeve 10, which is beneficial to improve the polishing effect.

[0057] Preferably, the rotating seat 6 is provided with a guide hole 19 for guiding the polishing assembly into the containing groove 18, the guide hole 19 is a horn structure, the small opening end of the guide hole 19 communicates with the containing groove 18, and the large opening end faces the polishing assembly. Specifically, the polishing disc 7 can be arranged corresponding to the edge of the containing groove 18, so as to avoid interference between the polishing disc 7 and the polishing assembly, and also to ensure the polishing effect of the polishing disc 7 on the surface of the hole steel template.

[0058] In actual application process, the lifting rod 11 drives the lifting sleeve 10 to rotate through the rotating seat 6, so that the lifting rod 11 and the rotating seat 6 will not rotate relative to each other, when the polishing assembly on the lifting rod 11 completes the polishing process of the hole of the hole steel template, the lifting rod 11 and the lifting sleeve 10 can be driven to rise, with the rising of the lifting rod 11, the counterweight polishing head 17 on the polishing 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 polishing piece 16 to rotate in vertical and horizontal directions, so as to gradually reduce the outer diameter of the polishing assembly, until the polishing assembly is completely received in the containing groove 18, then the lifting rod 11 and the lifting sleeve 10 can stop rising.

[0059] By setting the accommodating groove 18 for accommodating the polishing assembly on the rotating base 6, the accommodating groove 18 can play a good protective role on the polishing assembly, and at the same time, when the polishing disc 7 polishes the surface of the perforated steel formwork, the polishing assembly will not affect the movement of the polishing module 5, so that the wall climbing robot 1 can polish the perforated steel formwork along the preset route. At the same time, by setting the horn-shaped guide hole 19, the polishing assembly can be well guided, and after the hole polishing is completed, the polishing assembly is guided into the accommodating groove 18 to realize storage, which is convenient for the polishing module 5 to carry out subsequent polishing work of the perforated steel formwork or the inner wall of the hole, and is conducive to improving the polishing efficiency of the device.

[0060] Preferably, the counterweight polishing head 17 is rotatably installed on the polishing piece 16, and the rotation direction of the counterweight polishing head 17 is the vertical direction. Specifically, the counterweight polishing head 17 can adopt a conventional polishing head such as a polishing wheel or a polishing ball, and is rotatably installed on the polishing piece 16 by a conventional rotating shaft. The polishing piece 16 is provided with a mounting groove for mounting the counterweight polishing head 17. Those skilled in the art can also select a suitable counterweight polishing head 17 and its rotating installation method according to actual needs. It should be noted that the mass of the counterweight polishing head 17 can be set according to actual needs, and preferably the mass is greater than that of the polishing piece 16, so that when the lifting rod 11 rotates, the counterweight polishing head 17 can generate sufficient centrifugal force to drive the polishing piece 16 to rotate horizontally, thereby changing the overall outer diameter of the polishing assembly.

[0061] In actual application, by rotatably installing the counterweight polishing head 17 on the polishing piece 16, when the lifting rod 11 rises, the counterweight polishing head 17 and the inner wall of the guide hole 19 are in rolling friction, so that the inner wall of the guide hole 19 can better guide the counterweight polishing head 17, thereby realizing the storage of the polishing assembly in the accommodating groove 18. At the same time, when the lifting rod 11 descends to drive the polishing assembly to pass through the residual concrete in the hole, the counterweight polishing head 17 can also more easily pass through the residual concrete block by rotating, without causing obstruction to the polishing assembly. In addition, when the lifting rod 11 drives the polishing assembly to polish the concrete in the hole, under the condition that the lifting sleeve 10 limits the outer diameter of the polishing assembly, the counterweight polishing head 17 can tightly polish the inner wall of the hole, at this time, the side surface of the counterweight polishing head 17 mainly plays a polishing role.

[0062] Preferably, the polishing piece 16 is rotatably installed on the lifting rod 11 through the universal joint 22, and the lifting rod 11 is provided with a limiting part 21 corresponding to the position below the polishing piece 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 installed on the polishing piece 16 through a conventional screw connection, and the other end can be detachably assembled with the lifting rod 11 through a threaded connection. Those skilled in the art can also select other suitable universal joints 22 and their corresponding installation methods according to actual needs to realize the rotation and detachable assembly of the polishing piece 16 on the lifting rod 11, which will not be described here.

[0063] In actual application, the limiting part 21 can effectively limit the downward rotation of the polishing piece 16, which is beneficial to improve the stability of the polishing piece 16 on the lifting rod 11 and ensure the strength of the polishing piece 16 during polishing. Moreover, the limiting part 21 can effectively strengthen the connection between the polishing piece 16 and the lifting rod 11, so that the polishing piece 16 can remain stable on the lifting rod 11 when the counterweight polishing head 17 contacts the inner wall of the hole, thereby improving the stability of the polishing assembly during polishing and ensuring that the outer diameter of the polishing assembly remains unchanged when the polishing assembly ascends along with the lifting rod 11 to polish the inner wall of the hole, which is beneficial to improve the polishing accuracy of the hole of the steel formwork with holes and even achieve the required polishing accuracy in one polishing process, thereby improving the polishing efficiency.

[0064] Preferably, the lifting rod 11 is provided with a detachable drill bit 20 corresponding to the position below the polishing piece 16. Specifically, the drill bit 20 can be a conventional drill bit, which is fixed on the lifting rod 11 through a conventional screw connection. Those skilled in the art can also select a suitable drill bit and its corresponding installation method according to actual needs to realize the detachable assembly of the drill bit 20 on the lifting rod 11.

[0065] In actual application, the drill bit 20 is arranged on the lifting rod 11 to polish the concrete blocking the hole during the process that the lifting rod 11 extends into the hole of the steel formwork with holes, so that the polishing assembly can be easily polished in the hole in the subsequent polishing process. Therefore, the polishing assembly can not only polish the surface around the hole and the inner wall of the hole, but also polish the hole blocked by the concrete, thereby improving the applicability of the device to different polishing requirements.

[0066] Preferably, the polishing piece 16 is an arc-shaped rod structure. Specifically, the outer arc surface of the polishing piece 16 serves as a working surface for contacting the concrete. Compared with other polishing pieces 16, the arc-shaped rod structure of the polishing piece 16 not only meets the requirements of rotation, opening and storage, but also has higher structural strength and better polishing effect on the concrete.

[0067] In actual application, one side of the polishing piece 16 is provided with a cutting portion 23. Exemplarily, the cutting portion 23 is provided with a tapered surface or an inclined surface and is arranged on the outer arc surface side of the polishing piece 16 to improve the grinding effect of the polishing piece 16 on the concrete. In addition, after the drilling of the concrete blocking the hole is completed by using the drill bit piece 20, the polishing assembly can also be driven by the lifting rod 11 to extend into the drilled hole. In the process of the polishing assembly extending into the drilled hole, the cutting portion 23 on one side of the polishing piece 16 can also grind the concrete to expand the diameter of the drilled hole, so that the polishing assembly can more smoothly extend into the hole. Similarly, when the drill bit piece 20 is not used for drilling, the cutting portion 23 on the polishing piece 16 can also grind the concrete at the end of the hole to expand the diameter of the hole, so as to facilitate the extension of the polishing assembly into the hole.

[0068] Preferably, the polishing module 5 is provided with a protective cover 9, and the first driving assembly and the second driving assembly are arranged in the protective cover 9. Specifically, the protective cover 9 can be detachably installed on the shell of the polishing mold by a conventional method such as screwing. In actual use, the protective cover 9 can protect the rotating seat 6, the lifting sleeve 10, the lifting rod 11, the first driving assembly and the second driving assembly, and avoid the influence of the splashed dust on the movement of the above-mentioned components during polishing, which is conducive to improving the reliability of the device in use.

[0069] Optionally, the first driving assembly comprises a first telescopic cylinder 12, and the first telescopic cylinder 12 is circumferentially and evenly provided with at least two first telescopic cylinders 12. The lifting sleeve 10 is provided with a first connecting seat 13, and the first connecting seat 13 is rotatably installed on the lifting sleeve 10. The fixed end of the first telescopic cylinder 12 is arranged on the protective cover 9, and the telescopic end is connected with the first connecting seat 13. The second driving assembly comprises a second telescopic cylinder 14, and the second telescopic cylinder 14 is circumferentially and evenly provided with at least two second telescopic cylinders 14. The lifting rod 11 is provided with a second connecting seat 15, and the second connecting seat 15 is rotatably installed on the lifting rod 11. The fixed end of the second telescopic cylinder 14 is arranged on the protective cover 9, and the telescopic end is connected with the second connecting seat 15.

[0070] Optionally, those skilled in the art can also select other ways 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 can be installed on an assembly frame (not shown in the figure) by a conventional method such as screwing, then the assembly frame and the protective cover 9 are connected by a conventional method such as screwing, and finally the protective cover 9 is fixed on the shell of the polishing module 5 by a conventional method such as screwing, so that the protective cover 9 can shield the first telescopic cylinder 12 and the second telescopic cylinder 14. In addition, those skilled in the art can select other suitable installation methods according to actual needs to realize the stable assembly of the first telescopic cylinder 12 and the second telescopic cylinder 14, which will not be described here.

[0071] In practical application, two first telescopic cylinders 12 and two second telescopic cylinders 14 are arranged, and a person skilled in the art can arrange multiple according to actual needs, which will not be repeated here.

[0072] 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 a guide rail or a guide rod, or the first telescopic cylinder 12 and the second telescopic cylinder 14 are both arranged with two, and a person skilled in the art can select to arrange according to actual needs, which will not be repeated here.

[0073] On the basis of the above, the embodiment further provides a hole steel formwork polishing treatment method, which is realized by using the hole steel formwork polishing treatment device. By using the hole steel formwork polishing treatment method, the residual concrete at the hole of the hole steel formwork can be effectively polished and cleaned, the residual concrete at the edge of the hole of the hole steel formwork can be effectively removed, and the residual concrete in the hole and the hole can be effectively removed, so that the polishing treatment has better quality and higher efficiency.

[0074] Figure 9 A flowchart of the hole steel formwork polishing treatment method is shown in the embodiment of the application. Referring to Figure 9 The hole steel formwork polishing treatment method specifically includes the following steps:

[0075] Step S1, obtaining the position of the hole of the hole steel formwork and the position of the hole steel formwork polishing treatment device, and controlling the hole steel formwork polishing treatment device to move to the center of the hole.

[0076] Before the polishing treatment is performed, the hole positions on the steel template with holes can be measured or obtained. In this embodiment, the position of the polishing treatment device for the steel template with holes is taken as the starting point, and the hole positions on the steel template with holes are taken as the ending point to determine the working direction and working route of the polishing treatment device for the steel template with holes. It should be noted that when the hole positions on the steel template with holes are measured or obtained, the initial size of the holes also needs to be measured or obtained to ensure that the outer diameter size of the polishing assembly after extending into the hole is not greater than the initial size of the hole, so as to prevent the polishing piece or the inner wall of the hole from being damaged.

[0077] Specifically, the maximum descending height of the lifting sleeve can be experimentally or measured before actual use. By controlling the descending height of the lifting sleeve, the outer diameter size of the polishing assembly is limited by the lifting sleeve abutting against the upper surface of the polishing piece, so that the outer diameter size of the polishing assembly can match the initial size of the hole, thereby avoiding the bending of the polishing piece or the damage of the inner wall of the hole caused by the over-descending of the lifting sleeve.

[0078] In step S2, in the process that the polishing treatment device for the steel template with holes moves to the center of the hole, the power assembly on the polishing module drives the rotating seat to rotate, and the polishing disc on the rotating seat polishes the adhering matter on the surface of the steel template with holes.

[0079] Because the surface of the steel template with holes, especially the hole, is prone to residual concrete, in order to realize the subsequent cleaning of the concrete in the hole, the concrete on the surface of the steel template with holes needs to be polished first to loosen and shape the residual concrete at the hole.

[0080] In actual application, the polishing disc can polish from one side to the other side of the hole edge by driving the rotating seat to rotate by the power assembly on the polishing module and driving the polishing module to move by the wall-climbing robot. In the polishing process, the polishing disc can also move, crush and loosen the concrete at the hole, which is beneficial to the preliminary separation of the concrete and the inner wall of the hole, and the concrete blocking the hole and the concrete in the hole also has a certain probability of falling, which is beneficial to reducing the polishing difficulty of the residual concrete on the inner wall of the hole.

[0081] In step S3, when the lifting rod on the polishing treatment device for the steel template with holes moves to the center of the hole, the polishing treatment device for the steel template with holes is controlled to move so that the lifting rod can move in a circle with the center of the hole as the center and with a preset length as the radius, and in the moving process, the second driving assembly drives the lifting rod to lift for grinding treatment; wherein the preset length is less than the difference between the radius of the hole and the cross-sectional radius of the lifting rod.

[0082] Since the concrete blocking the hole can be thick, the polishing by the polishing disc alone can not form a hole on the surface of the concrete, so that the lifting rod and the polishing assembly on the lifting rod can not directly extend into the hole. Therefore, in the actual polishing process, after the lifting rod moves to the center of the hole, the hole-plate polishing device can also be driven to move, so that the lifting rod can move in a circle with the center of the hole as the center and the preset length as the radius to perform grinding on the surface of the concrete blocking the hole, to form an annular groove or multiple through holes on the surface of the concrete, so as to further break and loosen the concrete to facilitate forming a through hole on the surface of the concrete through which the lifting rod and the polishing assembly can pass.

[0083] It should be noted that the preset length should be less than the difference between the radius of the hole and the cross-sectional radius of the lifting rod, so as to prevent the lifting rod from interfering with the edge of the hole during the circular movement of the lifting rod, and to ensure that the lifting rod only polishes the concrete blocking the hole.

[0084] In actual application, during the circular movement of the lifting rod with the wall-climbing robot, the lifting rod can also be repeatedly raised and lowered, so that the drill on the lifting rod can contact the concrete blocking the hole to perform efficient grinding on the surface of the concrete and quickly form a through hole or an annular groove on the surface of the concrete.

[0085] Step S4, the hole-plate polishing device is controlled to move back to the original position. After the lifting rod on the polishing module moves to the center of the hole again, the second driving assembly is used to lower the lifting rod, so that the polishing assembly extends into the hole.

[0086] After the lifting rod is polished in the circular movement in the above steps, the concrete in the middle of the hole has been broken and fallen or has a reduced bonding force with the concrete at the edge of the hole. At this time, the concrete in the middle of the hole can be quickly pried open by lowering the lifting rod, so that the lifting rod and the polishing assembly can extend into the hole. At the same time, as the lifting rod rotates, the polishing assembly can also adjust the outer diameter under the action of centrifugal force, and finally make the counterweight polishing head abut against the inner wall of the hole.

[0087] Step S5, the first driving assembly is used to lower the lifting sleeve, and after the lifting sleeve abuts against the polishing piece 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.

[0088] When the polishing assembly on the lifting rod passes through the concrete on the inner wall of the hole and the counterweight polishing head contacts the inner wall of the hole, the first driving assembly can be used to lower the lifting sleeve, and the lifting sleeve abuts against the upper surface of the polishing piece to limit the polishing piece. At this time, the counterweight polishing head can abut against the inner wall of the hole, and the polishing assembly can form a structure similar to a hook in the hole, so as to ensure that the counterweight polishing head can continuously and stably polish the concrete on the inner wall of the hole.

[0089] Step S6, the second driving assembly drives the lifting rod to rise, and the first driving assembly drives the lifting sleeve to rise synchronously with the lifting rod, so as to ensure that the outer diameter of the polishing assembly remains unchanged when the polishing assembly polishes the attachments on the inner wall of the hole.

[0090] When the lifting rod and the lifting sleeve rise synchronously, the polishing assembly in the form of a claw can gradually polish the concrete on the inner wall of the hole from bottom to top. When the counterweight polishing head is blocked by the concrete block, not only can the counterweight polishing head continue to polish the concrete block, but also the claw-shaped polishing assembly can loosen the concrete block as the lifting rod rises, accelerating the separation of the concrete from the inner wall of the hole, which is beneficial to further improve the polishing efficiency. At the same time, through the synchronous rising of the lifting rod and the lifting sleeve, the outer diameter of the polishing assembly remains unchanged under the limiting action of the lifting sleeve, so as to ensure the polishing quality of the inner wall of the hole and avoid damaging the surface quality of the hole.

[0091] Step S7, when the polishing assembly on the lifting rod moves out of the hole and enters the accommodation slot of the rotating seat to complete the accommodation, stop the first driving assembly and the second driving assembly.

[0092] When the polishing assembly on the lifting rod moves out of the hole, the polishing of the hole is completed. Then, as the lifting rod continues to rise, the polishing assembly can be accommodated in the accommodation slot under the guidance of the guide hole. After the polishing assembly is accommodated in the accommodation slot, the first driving assembly and the second driving assembly can be stopped, and the polishing of the hole is completed.

[0093] Step S8, repeat steps S1 to S7 until the polishing of all holes on the hole steel formwork is completed.

[0094] Since the hole steel formwork generally has multiple holes, after repeating the above steps S1 to S7 to complete the polishing of the holes on the hole steel formwork one by one, the polishing of the hole steel formwork is completed.

[0095] The effects of the above scheme are described as follows:

[0096] The embodiment provides a hole steel template polishing treatment device and method, through integration of a polishing disc for polishing a hole steel template surface and a polishing assembly for polishing a hole of the hole steel template on a polishing module, effective cleaning of residual attachments of the hole steel template after use can be realized, polishing treatment effect is good, polishing treatment efficiency is high, and damage to surface quality of the hole steel template is not caused. In addition, through mounting of the lifting rod with the polishing assembly on the rotating seat through the lifting sleeve, synchronous driving of the polishing disc and the polishing assembly can be realized by rotating the rotating seat by the power assembly, simplification of the overall structure is realized, reliability is higher, and the lifting sleeve can also realize limiting of an outer diameter of the polishing assembly, ensures that the outer diameter of the polishing assembly remains unchanged when polishing an inner wall of the hole, and is favorable for further improving polishing treatment quality.
