Description

Technical Field

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

[0002] In bridge construction, large casting molds made of steel plates are typically used to shape the overall form of concrete components such as piers and abutments during the integral casting process. These steel formworks are characterized by high structural strength and high reusability, and are widely used in bridge engineering.

[0003] In actual construction, after the steel formwork is used, concrete residue (commonly known as "concrete skin") often remains on its surface, and it is also prone to rust, forming a rust layer. If these residues are not cleaned thoroughly in time, they will directly affect the quality of the next concrete pour, causing a decrease in the adhesion between the concrete and the formwork during the new round of pouring, affecting the molding accuracy, and even causing quality defects such as air bubbles and honeycomb.

[0004] Because bridge piers and abutments are enormous, the steel formwork they use is also quite large. It is typically stacked vertically during cleaning and storage to minimize space usage and facilitate subsequent construction. Therefore, the surface treatment of the steel formwork must be carried out by grinding and cleaning while the formwork is in a vertical position.

[0005] The current common method is for the operator to hold a long pole with an angle grinder attached to the end of the pole to grind the surface of the vertical steel formwork. However, this grinding method is difficult to effectively remove the strong-adhesion concrete skin and rust, and there are cases where the cleaning is not thorough. Summary of the Invention

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0037] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] The current common method involves an operator holding a long pole with an angle grinder attached to the end to grind the surface of the vertical steel formwork. This method has the following drawbacks:

[0041] 1. Limited cleaning effect: Angle grinders are handheld portable tools with limited output torque and fit, making it difficult to effectively remove strong concrete skin and thick rust. Especially when the template surface is uneven or has a lot of adhering material, the processing efficiency and cleaning quality cannot meet the construction requirements.

[0042] 2. Poor operational stability: Operators need to lift the long lever high or at an upward angle, causing the center of gravity of the entire grinding mechanism to deviate from the human control range, resulting in unstable operation, easy slippage and deviation, and affecting the adhesion between the grinding head and the template surface.

[0043] 3. High safety risks: Due to the large weight of the angle grinder, long-term high-lift operation can easily cause operator fatigue, and there is a safety hazard of the angle grinder falling off or the grinding head breaking off and flying out, which poses a threat to personnel on the construction site.

[0044] 4. High labor intensity and low degree of automation: This grinding method relies entirely on manual operation, which is labor-intensive and inefficient. It is not suitable for large-scale continuous cleaning operations and is also difficult to adapt to the development trend of bridge construction towards mechanization and automation.

[0045] Based on this, in the specific embodiments provided by the present invention, a steel formwork surface grinding device is provided, for reference... Figures 1 to 12 As shown, the steel template surface grinding device includes: a wall-climbing robot 1, an installation mechanism, and a grinding mechanism 2. The wall-climbing robot 1 has an installation position 101. The installation mechanism includes a frame assembly 3 and a drive assembly 4. The frame assembly 3 is detachably connected to the installation position 101, and the drive assembly 4 is installed on the frame assembly 3. The grinding mechanism 2 includes a first flange 201, a rotating rod 202, an end plate 203, a wire grinding component 204, and a diamond abrasive grinding component 205. One end of the rotating rod 202 is fixed to the first flange 201, and the other end is fixed to the end plate 203. The wire grinding component 204 and the diamond abrasive grinding component 205 are both installed on the end plate 203, and the wire grinding component 204 is arranged around the outside of the diamond abrasive grinding component 205. The first flange 201 can be connected to the drive assembly 4 so that the drive assembly 4 drives the grinding mechanism 2 to rotate.

[0046] Through the above technical solution, the coordinated operation of the wall-climbing robot 1, the installation mechanism, and the grinding mechanism 2 can adapt to the working environment of vertically placed steel formwork in bridge construction, and can clean the concrete residue and rust adhering to the surface of the steel formwork. The wall-climbing robot 1 has excellent climbing ability and can stably and closely follow the surface of the steel formwork. The frame component 3 in the installation mechanism is detachably connected to the installation position 101, facilitating installation or disassembly with the wall-climbing robot 1. The drive component 4 is installed on the frame component 3 and provides driving power to the grinding mechanism 2. Specifically, the grinding mechanism 2 is connected to the drive assembly 4 through the first flange 201, so that the drive assembly 4 can drive the rotating rod 202 to rotate. The end plate 203 is fixed at the end of the rotating rod 202. The end plate 203 is provided with a steel wire grinding part 204 and a diamond abrasive grinding part 205, thus forming a composite grinding structure. The diamond abrasive grinding part 205 has strong cutting ability and can efficiently remove highly adhesive concrete residue. The steel wire grinding part 204 has flexible fitting ability, which is suitable for removing floating rust or other impurities and plays an auxiliary cleaning role on the surface of the steel template.

[0047] In some embodiments, the wall-climbing robot 1 may employ related equipment in the prior art, such as: CN120382950A - Tracked wall-climbing robot unit and tracked wall-climbing robot or CN120135308A - A tracked magnetic adsorption wall-climbing robot.

[0048] For example, the combined action of the wire grinding part 204 and the diamond grinding part 205 can remove both rust and concrete residue. The diamond grinding part provides strong cutting power to effectively remove the highly adhesive concrete residue, while the wire grinding part 204 is used to remove loose rust, thereby improving the overall cleaning effect and meeting the cleanliness requirements of the formwork for the next concrete pour.

[0049] Meanwhile, the wall-climbing robot 1 drives the grinding mechanism 2 to move on the steel formwork, which can adapt to the cleaning operation of the steel formwork in a vertical state, thereby cleaning the steel formwork efficiently without the need for manual operation of the angle grinder, significantly reducing labor intensity and the risk of the angle grinder falling from a height, and avoiding the problem of incomplete cleaning of the steel formwork caused by uneven manual grinding. For multiple steel formworks, it can effectively improve the consistency of grinding operations, thus providing a good foundation for subsequent pouring.

[0050] For example, refer to Figure 6 As shown, a buffer mechanism 5 is provided between the grinding mechanism 2 and the drive assembly 4 to improve the adhesion and impact mitigation performance during the grinding process. The buffer mechanism 5 includes a first connecting plate 501, a second connecting plate 502, multiple spherical bearings 503, a bushing 504, a buffer rod 507, a first buffer spring 505, a second buffer spring 506, and a fixed end cap 509. Multiple spherical bearings 503 are mounted on the first connecting plate 501, and each spherical bearing 503 has a corresponding bushing 504 inside its inner ring. One end of the buffer rod 507 is fixedly connected to the second connecting plate 502, and the other end passes through the bushing 504 and extends to the first connecting plate. Above 501, the bushing 504 guides the buffer rod 507. The bushing 504 is fixedly connected to the inner ring of the corresponding spherical bearing 503, and there is no relative displacement. The buffer rod 507 can slide axially in the bushing 504. The buffer rod 507 is fitted with a first buffer spring 505 and a second buffer spring 506. The first buffer spring 505 is located between the first connecting plate 501 and the second connecting plate 502, and the second buffer spring 506 is located between the fixed end cover 509 and the fixed ring platform 508. Both the first buffer spring 505 and the second buffer spring 506 can absorb the impact force generated during the grinding process.

[0051] Specifically, when the grinding mechanism 2 encounters uneven areas on the surface of the steel template during actual operation, the buffer rod 507 can make the second connecting plate 502 make a small-amplitude adaptive angle adjustment under the coordinated action of multiple joint bearings 503, ensuring the uniformity of the contact between the grinding mechanism 2 and the surface of the steel template. At the same time, the coordinated cooperation of the first buffer spring 505 and the second buffer spring 506 can effectively absorb the impact generated during the grinding process, reduce vibration transmission, reduce the fatigue load of the system, and improve the stability and safety of grinding.

[0052] For example, when the grinding mechanism 2 is performing actual grinding operations, due to the contact reaction force with the steel template surface, a thrust is generated towards the installation mechanism and acts on the buffer rod 507. At this time, the buffer rod 507 is displaced relative to the bushing 504 in its axial direction, which causes the first buffer spring 505 to be compressed and the second buffer spring 506 to be stretched simultaneously. With the coordinated cooperation of the first buffer spring 505 and the second buffer spring 506, not only can the impact load and vibration energy generated during the grinding process be effectively absorbed, but also a continuous and stable rebound force can be provided when the degree of contact between the grinding head and the template surface changes, thereby ensuring that the grinding mechanism 2 always maintains appropriate contact pressure, enhancing the consistency of contact and the cleaning effect.

[0053] In some implementations, reference Figure 7 , Figure 11 and Figure 12 As shown, the wire grinding component 204 includes a first fastening component 2041 and a second fastening component 2042. The first fastening component 2041 has a first embedding groove 20411, and the second fastening component 2042 has a second embedding groove 20421. When the first fastening component 2041 and the second fastening component 2042 are fastened together, the first embedding groove 20411 will connect with the second embedding groove 20421, forming a continuous annular mounting groove for mounting the wire grinding component 204 as a whole onto the end plate 203. Simultaneously, the upper surface of the first fastening component 2041 is provided with a locking block 20412, and the second fastening component 2042 is provided with a locking rod 20422. The locking block 20412 is provided with a slot 204121, the locking rod 20422 is provided with a first through hole 204221, and the locking block 20412 is provided with a second through hole 204122. When the first... When the fasteners 2041 and 2042 are engaged, part of the locking rod 20422 is located in the slot 204121, and the first through hole 204221 and the second through hole 204122 are coaxially arranged. At this time, the first fastener 2041 and the second fastener 2042 can be fixed by bolts. In addition, in order to further improve the firmness between the wire grinding part 204 and the end plate 203, the first fastener 2041 is provided with a first fixing groove, the second fastener 2042 is provided with a second fixing groove, and the upper surface of the end plate 203 is provided with two fixing screws 206 corresponding to the first fixing groove and the second fixing groove respectively. At this time, the first fastener 2041 and the second fastener 2042 can be clamped and fixed by nuts to prevent the wire grinding part 204 from loosening or falling off the end plate 203 due to vibration or external force during the grinding process.

[0054] For example, both the lower surfaces of the first fastener 2041 and the second fastener 2042 are provided with grinding wires 6. The grinding wires 6 can effectively clean the surface of the steel template. That is, when the grinding wires 6 rotate, they can provide continuous and uniform mechanical friction to the surface of the steel template, effectively removing attached rust and concrete. At the same time, the grinding wires 6 have a certain degree of flexibility, which further enhances the fit with the surface of the steel template and reduces surface scratches and local damage caused by hard contact.

[0055] Meanwhile, when the grinding wire 6 wears down to a certain extent, personnel can quickly replace it with a new part by disassembling the first fastener 2041 and the second fastener 2042, avoiding repeated disassembly and assembly of the entire grinding mechanism 2, reducing maintenance costs and downtime, and significantly improving work efficiency.

[0056] In some implementations, reference Figures 7 to 10 As shown, the diamond abrasive polishing component 205 includes a polishing plate 2051, a limiting block 2052, an adjusting screw 2053, an adjusting nut 2054, an adjusting spring 2055, and a limiting post 2056. One end of the polishing plate 2051 is fixedly connected to the limiting block 2052, and the other end has an abrasive polishing block 7. The abrasive polishing block 7 is used to directly contact the surface of the steel template for powerful cleaning. The adjusting screw 2053 is fixedly connected to the end of the limiting block 2052 facing away from the polishing plate 2051. The limiting post 2056 is fixedly connected to the upper surface of the end plate 203, and the limiting post 2056 has a limiting cavity 20561 for receiving the limiting block 2052. The device includes a guide port 20562, which is connected to a limiting cavity 20561. The limiting cavity 20561 has an opening, through which the limiting block 2052 and the adjusting screw 2053 can extend into the limiting cavity 20561. At the same time, the adjusting screw 2053 can extend through the guide port 20562 to the outside of the limiting cavity 20561 and is connected to an adjusting nut 2054. An adjusting spring 2055 is sleeved on the adjusting screw 2053 and is located inside the limiting cavity 20561. One end of the adjusting spring 2055 abuts against the limiting block 2052, and the other end abuts against the bottom surface of the limiting cavity 20561 away from its own opening.

[0057] For example, the adjusting spring 2055 sleeved on the adjusting screw 2053 is tightened or loosened by rotating the adjusting nut 2054. Specifically, when the adjusting nut 2054 is rotated clockwise, the adjusting spring 2055 is further compressed; while rotating counterclockwise can release the compression force, causing the adjusting spring 2055 to rebound moderately. By controlling the amount of compression of the adjusting spring 2055, the initial preload and contact depth of the grinding plate 2051 can be adjusted.

[0058] Initial preload: Before grinding begins, the compression of the adjusting spring 2055 is controlled by adjusting nut 2054, so that the abrasive grinding block 7 generates an outward thrust towards the template before it even contacts the steel template.

[0059] Contact depth: The distance between the abrasive grinding block 7 and the surface of the steel template.

[0060] In some implementations, the introduction of the adjusting spring 2055 gives the grinding plate 2051 a certain elastic floating space. When there are local unevenness or vibration impact on the surface of the steel template, the grinding plate 2051 can generate a slight displacement buffer to avoid the problems of "fixed" or "skipped grinding" and improve the uniformity of cleaning.

[0061] In some embodiments, the outer contour of the limiting block 2052 is a quadrangular prism, and the inner wall contour of the limiting cavity 20561 is adapted to the outer contour of the limiting block 2052. The quadrangular prism shape has a directional limiting function, allowing the limiting block 2052 to move linearly along the axial direction only in the limiting cavity 20561. This effectively prevents the limiting block 2052 from rotating or twisting due to vibration or rebound force during the grinding process, thus affecting the grinding angle. At the same time, the inner wall contour of the limiting cavity 20561 is adapted to the outer contour of the limiting block 2052, so that the limiting block 2052 has a clear directional guidance when inserted into the limiting cavity 20561, avoiding assembly misalignment and helping to improve assembly efficiency and the accuracy of repeatability.

[0062] In some implementations, reference Figures 1 to 5 As shown, the frame assembly 3 includes a fixed frame 301 and an mounting frame 302. The fixed frame 301 is installed at the mounting position 101. The mounting frame 302 has an overlap groove 3021 and an insert plate 3022 is provided in the overlap groove 3021. The fixed frame 301 is provided with a slot 30121 corresponding to the insert plate 3022. That is, when the mounting frame 302 is installed on the fixed frame 301, part of the fixed frame 301 is accommodated in the overlap groove 3021 and the insert plate 3022 is embedded in the slot 30121, which effectively prevents the mounting frame 302 from shaking, displacing or deflecting during use, and improves the overall structural stability and safety.

[0063] Meanwhile, the drive component 4 is installed on the mounting frame 302, which serves as a support carrier, thereby transmitting the power of the drive component 4 to the grinding mechanism 2 to achieve the grinding operation.

[0064] In some implementations, reference Figures 1 to 5As shown, the drive assembly 4 includes a drive motor 402, a right-angle converter 403, and a drive shaft 404. The drive motor 402 is the power source, providing rotational driving force. It can be an AC motor or a servo motor. The output shaft of the drive motor 402 is connected to the input end of the right-angle converter 403. The function of the right-angle converter 403 is to change the output direction of the drive motor 402 by 90 degrees, thereby meeting the spatial layout requirements of the equipment and stably transmitting power to the drive shaft 404. One end of the drive shaft 404 is connected to the output end of the right-angle converter 403, and the other end is connected to a second flange 401. The second flange 401 is used to connect to the first connecting plate 501. That is, the drive assembly 4 and the buffer mechanism 5 can be quickly connected through the second flange 401.

[0065] In some implementations, reference Figures 1 to 5 As shown, the frame assembly 3 includes a support frame 303, which is fixedly connected to and located below the mounting frame 302, providing stable support for the mounting frame 302 and the drive assembly 4 above it. A third flange 3031 is provided on the support frame 303, and a support member 8 is provided on the fixed frame 301. A support groove 801 is formed in the support member 8, and its shape is adapted to the partial contour of the third flange 3031 to embed and support the third flange 3031, thereby achieving limiting fixation and stable connection of the support frame 303. Furthermore, the support frame 303 also has a mounting hole 3032 for installing a double bearing insert 9. The drive shaft 404 passes through the double bearing insert 9, which provides stable bidirectional support for the drive shaft 404, ensuring good coaxiality and transmission accuracy during rotation. At the same time, this structure can also effectively prevent the entire load on the drive shaft 404 from being borne by the right-angle converter 403, preventing problems such as uneven load distribution, wear, or loose connection caused by uneven force distribution, thereby improving the overall operational stability and service life of the system.

[0066] In some implementations, reference Figure 1 and Figure 5 As shown, the fixed frame 301 includes a fixed section 3011 and a support section 3012 that are vertically connected.
