Description

Technical Field

[0001] This invention belongs to the field of grinding equipment technology, and in particular relates to a sliding grinding device for grinding curved steel templates. Background Technology

[0002] In the construction of large-scale civil engineering projects such as bridges, tunnels, and viaducts, concrete structural components such as piers, abutments, and arches are typically constructed by integral casting. To ensure the dimensional and surface quality of the concrete structure, large curved steel formwork made of steel plates is commonly used for contour definition and support. This type of steel formwork has high structural strength and reusability, playing a crucial role in concrete construction.

[0003] However, during the use of steel formwork, its surface often develops impurities such as "concrete skin," rust spots, or welding burrs due to concrete residue, cement slurry adhesion, oxidation, and corrosion. If these defects are not effectively cleaned, they will directly affect the demolding effect and concrete forming quality in the next pouring process, easily causing structural defects such as air bubbles, honeycomb, and pitting. Therefore, steel formwork must undergo thorough surface cleaning and grinding after each use to ensure the smoothness of the formwork surface and extend its service life.

[0004] Meanwhile, to save space and facilitate pouring operations, these formwork panels are typically stacked almost vertically, which places higher demands on the grinding methods and equipment. Currently, the most common grinding methods are manual operation, where workers use handheld angle grinders with long handles to treat the surface of the formwork, or magnetic grinding robots that automatically attach to the surface. The former is labor-intensive, produces inconsistent grinding, and is inefficient, making it difficult to meet high-quality grinding requirements; while the latter, although efficient on large, flat surfaces, is limited by its rigid structure, making it unsuitable for grinding curved steel formwork.

[0005] Therefore, there is an urgent need for a device that can efficiently and conveniently grind curved steel formwork. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide a sliding grinding device for grinding curved steel formwork, which solves the problem of how to grind curved steel formwork quickly and efficiently.

[0007] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

The two drive components are arranged opposite each other along the length direction of the support plate and the second drive motor is located between the two drive components. The number of drive components is the same as the number of polishing components. Each drive component corresponds to one polishing component.

[0014] Furthermore, the skateboard is provided with a guide tube, and the lifting plate is provided with a through groove for the guide tube to pass through. The guide tube extends through the through groove to the bottom of the lifting plate, and the guide tube has a cable routing channel.

[0015] Furthermore, there are multiple fixing screws. When the end face of the fixing flange away from the connecting rod is in contact with the upper surface of the mounting body, the fixing screw passes through the fixing flange through the through hole on the fixing flange, and the fixing flange is located between the fixing nut and the mounting body.

[0016] Furthermore, the buffer component includes a sleeve, a threaded collar, a buffer spring, and a telescopic rod. The sleeve has a prismatic profile and a receiving cavity for housing the buffer spring. The sleeve also has a through hole located on the bottom surface of the receiving cavity. The threaded collar is fixedly connected to the sleeve. A stop ring plate is fixedly connected to the inner wall of the mounting hole. When the sleeve is located in the mounting hole, one end face of the sleeve is in contact with one end face of the stop ring plate, and the threaded collar extends out of the receiving cavity through the opening of the stop ring plate and is placed on the mounting hole. Inside the mounting cavity of the body, a locking nut is threadedly connected to the threaded collar.

Combined with the drive component, multiple flexibly connected arc grinding plates are rotated to grind the arc steel template. Specifically, the arc track and the sliding plate enable the grinding mechanism to adapt to the arc steel template, realize efficient, uniform and continuous surface grinding operation, significantly improve the grinding quality and consistency, reduce the intensity and error of manual operation, and thus effectively ensure the demolding effect and repeated service life of the steel template.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] In the specific embodiments provided in this disclosure, a sliding grinding device for grinding curved steel templates is provided, with reference to... Figures 1 to 12As shown, the grinding device includes: a base 1, a lifting machine 2, an arc-shaped track 3, a lifting plate 4, a support frame 5, and a grinding mechanism. The lifting machine 2 is installed on the upper surface of the base 1. The screw 201 of the lifting machine 2 is threaded with a mounting nut 202. The lifting plate 4 is detachably connected to the mounting nut 202. The lifting plate 4 is provided with an arc-shaped track 3. A sliding plate 301 is slidably connected to the arc-shaped track 3. The sliding plate 301 is provided with a mounting position for mounting the support frame 5. The support frame 5 is equipped with a grinding mechanism. The grinding mechanism includes a drive component 6 and a grinding component 7. The drive component 6 is used to drive the grinding component 7 to rotate. The polishing assembly 7 includes a mounting body 701, a buffer 702, and an arc-shaped polishing plate 703. The upper surface of the mounting body 701 is provided with a fixing member 704 for connecting the drive assembly 6. The side wall of the mounting body 701 has a mounting hole 7011 for mounting the buffer 702. The end of the buffer 702 facing away from the mounting body 701 is connected to the arc-shaped polishing plate 703. There are multiple arc-shaped polishing plates 703, which are arranged around the circumference of the mounting body 701. The shape of the multiple arc-shaped polishing plates 703 in the orthographic projection along the height direction of the mounting body 701 is circular.

[0044] In some embodiments, the sliding grinding device can adapt to curved steel templates, thereby efficiently grinding the curved steel templates. The sliding grinding device includes a base 1, a lifting platform 2, a curved track 3, a lifting plate 4, a support frame 5, and a grinding mechanism. The lifting platform 2 is mounted on the base 1, and the lead screw 201 of the lifting platform 2 is threadedly connected to the mounting nut 202. The lifting plate 4 is detachably connected to the mounting nut 202, allowing the grinding mechanism to be adjusted vertically. The lifting plate 4 is provided with an arc... The curved track 3 and the slide plate 301 can slide on the track. The slide plate 301 is provided with a mounting position for mounting the support frame 5. The support frame 5 is equipped with a grinding mechanism, which allows the grinding mechanism to move and grind along the arc contour of the steel template to be ground, significantly improving the matching degree and coverage of the grinding path. That is, the curvature of the curved track 3 can be customized so that it can be consistent with the curvature of the arc steel template to be ground, thereby ensuring that the grinding mechanism can more fully grind and remove impurities such as concrete skin.

[0045] For example, refer to Figure 1 and Figure 3As shown, the grinding mechanism consists of a drive assembly 6 and a grinding assembly 7. The drive assembly 6 drives the grinding assembly 7 to rotate, thereby automating and increasing the efficiency of the grinding operation and reducing reliance on manual labor. The grinding assembly 7 includes a mounting body 701, a buffer 702, and multiple arc-shaped grinding plates 703. The mounting body 701 is used to connect the drive assembly 6 and is provided with multiple mounting holes 7011 to install the buffer 702. The buffer 702 is connected to the arc-shaped grinding plates 703. The multiple arc-shaped grinding plates 703 are arranged around the circumference of the mounting body 701, and their orthographic projection in the height direction is circular. The structural design of the multiple arc-shaped grinding plates 703 not only expands the grinding coverage area, but also introduces the buffer 702 to provide flexible buffering for the arc-shaped grinding plates 703, effectively dealing with local irregularities or undulations on the surface of the steel template, thereby ensuring grinding uniformity and preventing over-grinding.

[0046] Furthermore, the grinding assembly 7 adopts a modular design, facilitating the replacement of different types of grinding elements according to varying construction needs. This enhances the versatility and maintenance efficiency of the device. For example, the outer wall of the arc-shaped grinding plate 703 can be equipped with grinding media of different materials or functions, such as grinding wire, sandpaper, diamond abrasive layers, resin grinding discs, or nylon polishing brushes. Among these, grinding wire is suitable for removing thicker concrete residues and stubborn rust, sandpaper and diamond abrasive layers are suitable for fine grinding and smoothing of the template surface, and nylon polishing brushes can be used to remove fine dust or perform fine polishing. By replacing different types of grinding plates, adjustments can be made flexibly to address different levels of contamination, roughness, or grinding stages (such as coarse grinding, fine grinding, and polishing) on ​​the template surface. This further improves the targeting and precision of the grinding operation, while also facilitating the rapid replacement of worn parts, shortening maintenance time, and enhancing the overall operational continuity and engineering adaptability of the equipment.

[0047] In some implementations, reference Figure 1 and Figure 3As shown, the support frame 5 includes a fixed support plate 501 and a mounting frame 502. The drive assembly 6 includes a first drive motor 601, a commutator 602, a drive rod 603, and a connecting rod 604. Both the first drive motor 601 and the commutator 602 are mounted on the support plate 501. The drive shaft of the first drive motor 601 is connected to the input end of the commutator 602, and the output end of the commutator 602 is connected to the drive rod 603. The mounting frame 502 is provided with a bearing seat 605. The drive rod 603 passes through the bearing seat 605 and through the mounting frame 502. A drive flange 606 is provided at the end of the drive rod 603 facing away from the first drive motor 601. A connecting flange 607 corresponding to the drive flange 606 is provided on the connecting rod 604. The end of the connecting rod 604 facing away from the connecting flange 607 is provided with a fixing flange 608 corresponding to the fixing member 704. The fixing member 704 is configured as a fixing screw, and a fixing nut 609 is threaded onto the fixing screw. Specifically, the commutator 602 is set to make the driving direction more flexible, so that the arc-shaped grinding plate 703 can make fuller contact with the surface of the arc-shaped steel template. The driving rod 603 is supported by the bearing seat 605 and passes through the mounting frame 502 to ensure axial stability and rotational accuracy during power transmission and avoid swaying and wobble during high-speed rotation. The detachable connection of the driving flange 606, the connecting flange 607 and the fixing flange 608 ensures torque transmission efficiency and facilitates maintenance or replacement of components.

[0048] In some implementations, reference Figure 2 As shown, to achieve automatic sliding of the grinding mechanism on the arc-shaped track 3, a second drive motor 3011 is provided on the slide plate 301 to drive it to move along the arc-shaped track 3. The output shaft of the second drive motor 3011 is connected to a drive gear, and a rack is provided on the side wall of the arc-shaped track 3 to mesh with the drive gear, forming a gear and rack meshing drive structure. This allows the slide plate 301 to move stably along the arc-shaped track 3 under the drive of the second drive motor 3011. Furthermore, there are two drive components 6, which are arranged opposite each other along the length of the support plate 501. The second drive motor 3011 is located between the two drive components 6, forming a symmetrical distribution structure, which helps to balance the overall load and concentrate the transmission of driving force. At the same time, the number of drive components 6 corresponds one-to-one with the number of grinding components 7, that is, each drive component 6 is connected to a grinding component 7, ensuring that multiple grinding heads can operate synchronously and work together during the sliding process.

[0049] In some implementations, reference Figure 2As shown, in order to plan the wiring harness of the first drive motor 601 and the second drive motor 3011 as a whole and ensure their safe operation, a guide tube 3012 is provided on the slide plate 301, and a through groove 401 is provided on the lifting plate 4 for the guide tube 3012 to pass through. This allows the guide tube 3012 to extend through the through groove 401 to the bottom of the lifting plate 4, thereby guiding the cable to the base 1 without interfering with the movement of the grinding mechanism. The guide tube 3012 is provided with a cable routing channel 30121, which is used to accommodate and organize the wiring harnesses of the first drive motor 601 and the second drive motor 3011. This ensures that the wiring harnesses are always properly guided and flexibly buffered during the overall movement of the device, avoiding problems such as wiring harness fatigue, damage or poor contact caused by repeated bending, pulling or tangling.

[0050] For example, by setting the guide tube 3012, the wiring harnesses of the first drive motor 601 and the second drive motor 3011 can be centrally managed, realizing orderly wiring and routing of the wiring harnesses and avoiding messy distribution of the wiring harnesses that would affect the overall movement of the device. At the same time, the guide tube 3012 extends to the bottom of the lifting plate 4 after passing through the through groove 401, which can maintain a relatively stable relationship between the wiring harness and the sliding plate 301 during the lifting process, effectively solving the problem of wiring harness pulling caused by the up and down movement of the sliding plate 301 and extending the service life of the wiring harness.

[0051] In some implementations, reference Figures 3 to 6 As shown, in order to ensure the stable installation of the grinding assembly 7 and to have good transmission reliability, there are multiple fixing screws. When the end face of the fixing flange 608 away from the connecting rod 604 is in contact with the upper surface of the mounting body 701, the fixing screws pass through the through holes on the fixing flange 608. The fixing flange 608 is located between the fixing nut 609 and the mounting body 701. The clamping and fixing by multiple fixing nuts 609 ensures the uniform force on the connecting parts, enhances the stability and shock resistance of the entire grinding assembly 7, and effectively avoids displacement or loosening during the grinding process.

[0052] In some implementations, reference Figures 5 to 12As shown, the buffer 702 includes a sleeve 7021, a threaded collar 7022, a buffer spring 7023, and a telescopic rod 7024. The sleeve 7021 has a prismatic overall shape and an internal receiving cavity 70211 for accommodating the buffer spring 7023. Its bottom surface has a through hole for the telescopic rod 7024 to pass through. The threaded collar 7022 is fixedly connected to the outside of the sleeve 7021. The threaded collar 7022 can pass through the mounting hole 7011 of the mounting body 701 and is axially positioned by a stop ring plate 7025 provided on the inner wall of the mounting hole 7011. When the sleeve 7021 is inserted into the mounting hole 7011, its end face is in contact with one end of the stop ring plate 7025. The threaded collar 7022 passes through the opening hole 70251 of the stop ring plate 7025 and extends into the mounting cavity 7012 of the mounting body 701. A locking nut 7026 is connected to the threaded collar 7022. The locking nut 7026 fits against the abutment surface of the stop ring plate 7025 away from the buffer spring 7023, forming an axial limit and lock for the sleeve 7021. The threaded collar 7022 is also provided with a through hole, which communicates with the through hole at the bottom of the receiving cavity 70211. The telescopic rod 7024 passes through the through hole and the through hole in sequence and extends into the mounting cavity 7012. The telescopic rod 7024 includes a snap-fit ​​section 70241 and an adjusting section 70242. The diameter of the snap-fit ​​section 70241 is larger than that of the adjusting section 70242. One end of the snap-fit ​​section 70241 is fixed to the arc-shaped grinding plate 703, and the other end is connected to the adjusting section 70242. The adjusting section 70242 is threadedly connected to the mounting body 701 through the adjusting nut 7027.

[0053] For example, the buffer spring 7023 provides the arc-shaped grinding plate 703 with a certain axial flexibility, which can automatically generate expansion and contraction buffer according to the local undulations of the arc-shaped steel template surface during the grinding process, avoiding local over-grinding, scratches or template damage caused by rigid grinding, thereby improving the uniformity and quality of the overall grinding. At the same time, the telescopic rod 7024 adopts a combination of snap-fit ​​section 70241 and adjustment section 70242, which can not only achieve a stable connection of the arc-shaped grinding plate 703, but also adjust its extension length through the adjustment nut 7027, thereby flexibly controlling the grinding depth and adapting to different template curvatures or grinding requirements.

[0054] In some implementations, reference Figure 1 and Figure 2As shown, to further improve the structural stability and operational accuracy of the sliding grinding device during the lifting process, the device is also equipped with a support column 8 and a stabilizing plate 801. One end of the support column 8 is fixedly connected to the base 1, and the other end is connected to the stabilizing plate 801. The stabilizing plate 801 is equipped with a stabilizing bearing seat 803 for installing the lifting screw 201. The stabilizing bearing seat 803 is used to support and position the upper end of the screw 201, so that the screw 201 remains vertical during rotation and avoids shaking. In addition, to ensure the guiding and anti-deviation performance of the lifting plate 4 during the lifting process, a linear bearing 802 is also installed on the lifting plate 4. Each support column 8 passes through the linear bearing 802 and through the lifting plate 4 in sequence. At the same time, there are multiple support columns 8, which are arranged in a ring around the screw 201, thereby forming multiple axial fulcrums in the lifting system to achieve all-round guidance and stable support for the lifting plate 4.

[0055] In some implementations, reference Figure 1 and Figure 2 As shown, to further improve the support stability and smooth sliding of the skateboard 301 when moving along the arc-shaped track 3, multiple support omnidirectional balls 9 are installed on the upper surface of the lifting plate 4. These support omnidirectional balls 9 are arranged at intervals on the outer side of the arc-shaped track 3 to support the skateboard 301 from below. The support omnidirectional balls 9 have a structure that allows free rotation in multiple directions, enabling them to automatically adjust the contact angle according to the movement path of the skateboard 301 as it moves along the arc-shaped track 3, providing low-friction support and playing an auxiliary role in load-bearing and guidance.

[0056] In some embodiments, to achieve efficient and uniform treatment of the surface of the curved steel template, the sliding grinding device adopts a layer-by-layer grinding operation. Specifically, the rotation of the lead screw 201 first drives the lifting plate 4 to move up and down vertically, controlling the height of each lift to achieve layered treatment of the surface of the curved steel template. When the lifting plate 4 moves to the set height, the lead screw 201 stops rotating. At this time, the second drive motor 3011 starts, driving the slide plate 301 to slide along the length of the curved track 3, thereby driving multiple grinding components 7 connected to the slide plate 301 to move synchronously. At the same time as the second drive motor 3011 starts, the first drive motor 601 starts working, driving multiple curved grinding plates 703 in the grinding components 7 to rotate and grind, thereby completing the surface treatment of the entire curved template area corresponding to that height.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
