Description

Technical Field

[0001] This invention belongs to the field of box girder formwork cleaning, specifically involving a formwork grinding device. Background Technology

[0002] Box girder formwork is a crucial construction tool in industrial construction, used to shape concrete beams. After the beams are cast, concrete residue remains on the formwork surface, necessitating grinding. Currently, box girder formwork grinding is primarily done manually. However, as the shortcomings of manual grinding become increasingly apparent, various contour grinding equipment has emerged on the market specifically designed for grinding box girder formwork.

[0003] For example, the cleaning device in Chinese utility model patent CN217861913U has the following problems: When setting up the cleaning device inside the box girder, it is necessary to install a track on the outside of the box girder and install rollers on both sides of the moving frame of the cleaning device so that the rollers cooperate with the track and the moving frame moves along the track. This method makes the entire setup of the cleaning device cumbersome and difficult, thus increasing the construction period. Moreover, the track spacing is difficult to control, and the track needs to be frequently disassembled and reassembled, further increasing the number of procedures and the construction period. On the other hand, the need to set up the moving frame results in a large weight and height of the whole machine, making it inconvenient to operate. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a template grinding device that can be adapted to grinding templates of different types of box girders and is convenient and quick to set up and move. This invention provides a template grinding device, including a template grinding device body and grinding components; the position of the grinding roller in the grinding components is adjustable; the grinding components include a side mold grinding structure, a wing plate grinding structure, a vertical mold grinding structure, and a bottom mold grinding structure; the side mold grinding structure is located on the side of the template grinding device body and is used to grind the side molds of the box girder; the wing plate grinding structure is located above the side of the template grinding device body and is used to grind the wing plates of the box girder; the vertical mold grinding structure is located above the side of the template grinding device body and is used to grind the vertical molds of the box girder; the bottom mold grinding structure is located at the bottom of the template grinding device body and is used to grind the bottom molds of the box girder; a traveling structure is also provided below the template grinding device body, which carries the template grinding device body to move within the box girder, thereby performing grinding along the longitudinal direction of the box girder.

[0005] Furthermore, the template grinding device body has side mold grinding structures, wing plate grinding structures, and vertical mold grinding structures on both sides. Furthermore, two sets of side mold grinding structures are arranged side-by-side and spaced apart on one side of the template grinding device body, with the bottom mold grinding structure, wing plate grinding structure, and vertical mold grinding structure positioned between the intervals of the two sets of side mold grinding structures. Furthermore, it also includes a dust collection assembly, the dust collection hood of which is located on the side of the template grinding device body and faces the side mold; the dust collection hood is located within the dust collection space enclosed by the bottom mold grinding structure, wing plate grinding structure, vertical mold grinding structure, and the two sets of side mold grinding structures; the grinding rollers in the grinding assembly rotate and grind towards the dust collection space. Furthermore, side guide wheels are provided on both side walls of the template grinding device body, with at least two side guide wheels arranged side-by-side and spaced apart on one side of the template grinding device body. Furthermore, the lateral guide wheels are retractably mounted on the formwork grinding device body. Furthermore, the formwork grinding device also includes a spray assembly, which includes a water tank, a water pump, and a plurality of spray pipes disposed on the front and / or rear side of the formwork grinding device body; a spray bracket is disposed on the front and / or rear side of the formwork grinding device body, and the spray bracket has a plurality of mounting holes evenly distributed laterally, with the spray pipes detachably mounted in the mounting holes.

[0006] The beneficial effects of this invention are as follows: the template grinding device provided by this invention can grind all templates on a box girder at once, thereby improving the grinding efficiency of the box girder. Furthermore, by setting the grinding rollers in the grinding assembly to be position-adjustable, it can adapt to grinding operations on box girders of different models and / or sizes. It also facilitates the hoisting of this template grinding device into the box girder. Before hoisting, the grinding rollers in each grinding structure can be adjusted to be close to the template grinding device body. At this point, the overall external dimensions of the template grinding device are smaller than the internal dimensions of the box girder, making it easy to hoist the template grinding device into the box girder. After hoisting, the positions of each grinding roller are adjusted to fit against the corresponding template for high-quality grinding and cleaning. Moreover, by setting a traveling structure at the bottom of the template grinding device body, compared to conventional methods of hoisting or using top-mounted traveling wheels, it is not necessary to lay tracks on the outside of the box girder, saving the track laying step, improving grinding efficiency, and also reducing the weight and size of the template grinding device, thus facilitating hoisting.

[0013] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0014] like Figures 1-25 As shown, the present invention provides a template grinding device, including a template grinding device body 1 and a grinding assembly. The template grinding device body 1 is used to support the grinding assembly and connect multiple grinding structures in the grinding assembly into a whole, thereby synchronously grinding each template on the box girder 10. The position of the grinding rollers in the grinding assembly is adjustable. The grinding assembly includes a side mold grinding structure 2, a wing plate grinding structure 3, a vertical mold grinding structure 4, and a bottom mold grinding structure 5. Each of the side mold grinding structure 2, wing plate grinding structure 3, vertical mold grinding structure 4, and bottom mold grinding structure 5 has a grinding roller, and the position of each grinding roller can be adjusted. The side mold grinding structure 2 is disposed on the side of the template grinding device body 1 and is used to grind the side mold 102 of the box girder 10. The wing plate... The grinding structure 3 is located above the side of the template grinding device body 1, and the grinding roller of its wing plate grinding structure 3 is horizontally arranged above the side of the template grinding device body 1 for grinding the wing plate 103 of the box girder 10; the vertical mold grinding structure 4 is located above the side of the template grinding device body 1, and the grinding roller of its vertical mold grinding structure 4 is vertically arranged above the side of the template grinding device body 1 for grinding the vertical mold 104 of the box girder 10; the bottom mold grinding structure 5 is located at the bottom of the template grinding device body 1 for grinding the bottom mold 101 of the box girder 10; a traveling structure 6 is also provided below the template grinding device body 1, which is used for the template grinding device body 1 to travel inside the box girder 10 and then grind along the longitudinal direction of the box girder 10.

[0015] The template grinding device provided by this invention can grind all templates on the box girder 10 at once, including the bottom template 101, side templates 102, wing plates 103, and vertical template 104, thereby improving the grinding efficiency of the box girder 10. Furthermore, the grinding rollers in the grinding assembly are position-adjustable, which allows for grinding operations on box girders 10 of different models and / or sizes. It also facilitates the hoisting of the template grinding device into the box girder 10. Before hoisting, the grinding rollers in each grinding structure can be adjusted to be close to the template grinding device body 1. At this time, the template grinding... The overall dimensions of the grinding device are smaller than the internal dimensions of the box girder 10, making it easy to hoist the template grinding device into the box girder 10. After hoisting, the positions of each grinding roller are adjusted to fit against the corresponding template for high-quality grinding and cleaning. Specifically, the grinding rollers on the side template grinding structure 2 fit against the side template 102 of the box girder 10; the grinding rollers on the wing plate grinding structure 3 fit against the wing plate 103 of the box girder 10; the grinding rollers on the vertical template grinding structure 4 fit against the vertical template 104 of the box girder 10; and the grinding rollers on the bottom template grinding structure 5 fit against the bottom template 101 of the box girder 10. Moreover, by setting up the traveling structure 6, which is located at the bottom of the template grinding device body 1, compared to the conventional method of hoisting or placing wheels on top, it is not necessary to lay tracks on the outside of the box girder 10, thus saving the track laying step, improving grinding efficiency, and reducing the weight and size of the template grinding device, thereby facilitating hoisting.

[0016] In one embodiment, the side mold grinding structure 2, the wing plate grinding structure 3, and the vertical mold grinding structure 4 are provided on both sides of the template grinding device body 1. Since the box girder 10 is generally roughly symmetrical, that is, the side mold 102, the wing plate 103, and the vertical mold 104 are provided on both sides of the bottom plate 101 of the box girder 10, the side mold grinding structure 2, the wing plate grinding structure 3, and the vertical mold grinding structure 4 are provided on both sides of the template grinding device body 1. On the one hand, all templates can be ground at the same time. On the other hand, the entire template grinding device can be set within the box girder 10 with left and right limits. Thus, when the entire template grinding device moves longitudinally, the movement stability of the template grinding device can be improved.

[0017] In one embodiment, two sets of side mold grinding structures 2 are arranged side-by-side and spaced apart on one side of the template grinding device body 1. This improves the grinding effect of the side mold 102, allowing for two grinding passes on a single side mold 102. In a preferred embodiment, the side mold grinding structure 2 located upstream in the moving direction of the template grinding device is used for rough grinding, while the side mold grinding structure 2 located downstream is used for fine grinding. Furthermore, the two sets of side mold grinding structures 2 on one side provide stable and reliable support for the template grinding device, combined with the other side... The two sets of side mold grinding structures 2 enable the template grinding device to move stably and reliably along the longitudinal direction of the box girder 10 in the left and right directions. The bottom mold grinding structure 5, the wing plate grinding structure 3, and the vertical mold grinding structure 4 are arranged between the two sets of side mold grinding structures 2. The bottom mold grinding structure 5 is located at the lower end of the side mold grinding structure 2, and the wing plate grinding structure 3 and the vertical mold grinding structure 4 are located at the upper end of the side mold grinding structure 2. This arrangement allows for a reasonable arrangement of multiple grinding structures, ensuring that the multiple grinding structures do not interfere with each other but can interact with each other, thereby improving the stability of movement.

[0018] In one embodiment, the template polishing device further includes a dust collection component 7. The dust collection hood 71 of the dust collection component 7 is disposed on the side of the template polishing device body 1 and faces the side mold 102. The dust collection hood 71 is disposed within the dust collection space enclosed by the bottom mold polishing structure 5, the wing plate polishing structure 3, the vertical mold polishing structure 4, and the two sets of side mold polishing structures 2. That is, the bottom mold polishing structure 5 serves as the bottom plate, the wing plate polishing structure 3 and the vertical mold polishing structure 4 serve as the top plate, and the two sets of side mold polishing structures 2 serve as two side plates enclosing a rectangular dust collection space. The dust collection hood 71 is disposed within the dust collection space. The polishing rollers in the polishing component rotate and polish towards the dust collection space, so that the dust generated by polishing moves towards the dust collection space and is sucked away and collected by the dust collection hood 71. In this embodiment, multiple sets of grinding components enclose a dust-collecting space. This serves two purposes: firstly, it traps the dust generated by the grinding components, preventing excessive dust from being released into the environment and polluting it, thus affecting the health of workers; secondly, it facilitates efficient dust collection by the dust collection hood 71 without interfering with the adjustment and grinding of each grinding structure, and provides excellent dust collection, effectively preventing dust pollution from grinding. Additionally, the dust collection assembly 7 includes a dust collection fan 73 mounted on the top of the template grinding device body 1 and a dust collection pipe 72 located in the middle of the template grinding device body 1. One end of the dust collection pipe 72 is connected to the dust collection hood 71, and the other end is connected to the dust collection fan 73. In this embodiment, the dust collection assembly 7 is mounted on the template grinding device body 1.

[0019] In one embodiment, the walking structure 6 consists of four walking wheels 61 located at the bottom of the template grinding device body 1, wherein at least two of the walking wheels 61 on one side have an active rotation function as driving wheels. Preferably, a wheel sensor 62 is also provided at the bottom of the template grinding device body 1, located on the side of the walking wheels 61. The wheel sensor 62 is used to monitor the distance between the bottom of the walking wheels 61 and the bottom mold 101, detect whether the template grinding device has traveled to the designated position, and prevent the template grinding device from traveling beyond the edge of the template.

[0020] In a preferred embodiment, a support mechanism 15 is also hinged to the template grinding device body 1. The support mechanism 15 is preferably provided at both ends of the template grinding device body 1. When the template grinding device does not need to move, the support mechanism 15 can be rotated to support it and fix the position of the entire template grinding device. When it needs to move, the support mechanism 15 is rotated down to release the moving structure 6 from the bottom mold 101. In a preferred embodiment, the support mechanism 15 includes four support legs. Specifically, two support legs are hinged to the front end of the template grinding device body 1 and two support legs are hinged to the rear end of the template grinding device body 1. The support and lowering of the template grinding device body 1 are performed by rotating the support legs.

[0021] In one embodiment, side guide wheels 11 are provided on both side walls of the template grinding device body 1. At least two side guide wheels 11 are arranged side by side and spaced apart on one side of the template grinding device body 1. In a preferred embodiment, one side guide wheel 11 is provided at the front end, middle end and rear end of one side of the template grinding device body 1, that is, three on one side and six side guide wheels 11 in total. The side guide wheels 11 are non-powered wheels and are mainly used to assist the template grinding device in moving longitudinally along the box girder 10. In one preferred embodiment, the side guide wheels 11 are telescopically mounted on the template grinding device body 1, that is, the side guide wheels 11 are mounted on the template grinding device body 1 through a telescopic elastic mechanism. The telescopic elastic mechanism is extended in the default state. When subjected to external compressive force, it will compress the elastic element to shrink. When the template grinding device moves longitudinally along the box girder 10 and encounters a pit on the template working surface, only one wheel on each side can be suspended in the air, while the other two wheels remain in close contact with the template working surface to achieve a stable guiding effect. In addition, when encountering protrusions on the working surface of the template, the telescopic structure can retract the side guide wheel 11, thus allowing it to pass through the protrusion smoothly.

[0022] In one embodiment, the template grinding device further includes a spray assembly 8, which includes a water tank 81, a water pump, and a plurality of spray pipes 82 disposed on the front and / or rear side of the template grinding device body 1. The spray pipes 82 are used to spray the template that has been ground or is to be ground with the required liquid, such as water or a release agent, which can be selected as needed. A spray bracket 83 is disposed on the front and / or rear side of the template grinding device body 1. The spray bracket 83 has a plurality of mounting holes 831 evenly distributed along the side. The spray pipes 82 are detachably disposed in the mounting holes 831, thereby facilitating the adjustment of the installation position of the spray pipes 82 and realizing the adjustment of the spray position.

[0023] like Figures 4-7 As shown, in one embodiment, the side mold grinding structure 2 includes a side mold grinding roller assembly 21 and a position adjustment assembly 22. The side mold grinding structure 2 is disposed on the side wall of the template grinding device body 1 and is used to install and support the entire side mold grinding mechanism. It is also used to grind the side mold 102 of the box girder 10 template. In specific use, the template grinding device body 1 is also provided with a walking structure, which drives the entire side mold grinding structure 2 to move and grind the side mold 102 along the length direction of the side mold 102. The side mold grinding roller assembly 21 is a specific grinding component used to grind the hard concrete retained on the side mold so that it can be used as the side mold of the box girder 10 template in the next use. The position adjustment assembly 22 is used to adjust the position of the side mold grinding roller assembly 21 relative to the template grinding device body 1, so that it can be adapted to grind the side molds of box girders 10 of different models and / or different sizes. It also facilitates the installation of the side mold grinding structure 2 into the box girder 10 template.

[0024] Specifically, the position adjustment component 22 includes an upper hinge 221, an upper fulcrum drive 222, and a lower fulcrum drive 223. One end of the upper hinge 221 is hinged to one end of the side mold grinding roller assembly 21, and the other end is hinged to the template grinding device body 1, so that the side mold grinding roller assembly 21 can move relative to the template grinding device body 1, and the movement stroke is limited by the rotation stroke of the upper hinge 221. The upper fulcrum drive 222 is fixedly mounted on the template grinding device body 1, and the output end of the upper fulcrum drive 222 is movably connected to the upper hinge 221 to drive the upper hinge 221 to swing. One end of the lower fulcrum drive 223 is hinged to the template grinding device body 1, and the other end is hinged to the other end of the side mold grinding roller assembly 21; thereby realizing the movement of the side mold grinding roller assembly 21. The other end of the mold grinding roller assembly 21 is displacement controlled. Combined with the upper hinge 221 and the upper fulcrum drive 222, the position of the side mold grinding roller assembly 21 can be adjusted. When the output ends of the upper fulcrum drive 222 and the lower fulcrum drive 223 have the freedom of movement (for example, when the upper fulcrum drive 222 and the lower fulcrum drive 223 are cylinders without locks, and they will extend and retract under external force after the output ends are extended), the side mold grinding roller assembly 21 can have the freedom of movement in the left and right direction (grinding direction) relative to the template grinding device body 1, and also has the freedom of movement in the up and down direction. In this way, the side mold grinding roller assembly 21 can be reset when it encounters a large protrusion on the side mold 102, avoiding damage caused by excessive rigid impact. At the same time, it can also perform grinding operations on the large protrusion on the side mold 102.

[0025] The side mold grinding structure 2 of the template grinding device provided in this embodiment has the following effects: 1. The cooperation between the upper hinge 221 and the upper fulcrum drive 222 makes the movement trajectory of the moving hinge point in the side mold grinding roller assembly 21 driven by the upper fulcrum drive 222 predictable. Moreover, the upper hinge 221 can also serve as a support and guide structure, improving the connection strength and rigidity between the side mold grinding roller assembly 21 and the template grinding device body 1, avoiding the side mold grinding roller assembly 21 from shaking or displacing relative to the template grinding device body 1 at angles and directions other than the grinding direction, and improving the stability of the structure. 2. The cooperation of the upper hinge 221, the upper fulcrum drive 222, and the lower fulcrum drive 223 enables various posture controls on the position and angle of the side mold grinding roller assembly 21. On one hand, it allows the side mold grinding roller assembly 21 to conform to different models and / or different sizes of side molds 102 for high-precision grinding. On the other hand, when the output ends of the upper fulcrum drive 222 and the lower fulcrum drive 223 have a certain degree of freedom, the entire side mold grinding roller assembly 21 can have a degree of freedom to move in the left and right directions, as well as a small degree of freedom to move up and down. This allows the side mold grinding roller assembly 21 to reset when it encounters a large protrusion on the side mold 102, avoiding damage caused by excessive rigid impact. It also allows for grinding operations on large protrusions on the side mold 102. This improves the applicability of the equipment and the grinding effect. On the other hand, the cooperation of the upper hinge 221, the upper fulcrum drive 222, and the lower fulcrum drive 223 also facilitates the installation of this side mold grinding structure 2 into the box girder 10 template. Specifically, when installing this side mold grinding structure 2 into the box girder 10 template, the upper fulcrum drive 222 and the lower fulcrum drive 223 can first drive the side mold grinding roller assembly 21 to approach and retract into the template grinding device body 1. After the installation is completed, the side mold grinding roller assembly 21 is then driven to unfold and adhere tightly to the side mold 102 to complete the grinding with high quality. 3. The overall structure is simple and reliable, highly compact, has low manufacturing and maintenance costs, and provides good grinding results.

[0026] In one embodiment, the upper hinge member 221 is provided with a sliding groove 2213. The output end of the upper fulcrum drive member 222 is slidably engaged with the sliding groove 2213 via a pin 2222. The upper fulcrum drive member 222 drives the pin 2222 to slide along the length direction of the sliding groove 2213, thereby causing the upper hinge member 221 to swing. Specifically, the upper hinge member 221 is provided with a sliding groove 2213, and preferably the extension line of the length direction of the sliding groove 2213 intersects the plane containing the two hinge axes of the upper hinge member 221. The upper fulcrum drive member 222 is fixedly mounted on the template grinding device body 1, and the output end of the upper fulcrum drive member 222 is slidably engaged with the sliding groove 2213. In this embodiment, for ease of explanation, the hinge point between the upper hinge member 221 and the template grinding device body 1 constitutes a fixed hinge point, and the upper hinge member 221 and the side mold grinding roller... The hinge point of component 21 constitutes a movable hinge point, and the engagement point between the output end of the upper fulcrum drive 222 and the slide groove 2213 constitutes a movable hinge point. The fixed hinge point, movable hinge point, and movable hinge point always form a triangle, wherein the position of the fixed hinge point always remains unchanged, the connection between the fixed hinge point and the movable hinge point is the long side of the triangle, and the length of the long side always remains unchanged. The vertex of the triangle opposite to the long side, that is, the movable hinge point, can move along the output direction of the upper fulcrum drive 222, thereby causing the movable hinge point to swing. (Refer to...) Figure 4 and Figure 7 The linear displacement distance of the movable hinge point is less than the swing distance of the moving hinge point, that is, the swing amplitude of the moving hinge point will be greater than the movement amplitude of the upper fulcrum drive component 222, thus achieving a stroke amplification effect.

[0027] In this embodiment, the cooperation between the upper hinge 221 and the upper fulcrum drive 222 can, on the one hand, make the movement trajectory of the moving hinge point in the side mold grinding roller assembly 21 driven by the upper fulcrum drive 222 predictable, and on the other hand, can amplify the output stroke of the upper fulcrum drive 222, thereby reducing the requirements on the upper fulcrum drive 222 and improving the compactness of the structure. In this embodiment, the upper hinge 221 serves two purposes: firstly, it makes the movement trajectory of the moving hinge point in the side mold grinding roller assembly 21 driven by the upper fulcrum drive 222 predictable; secondly, it amplifies the output stroke of the upper fulcrum drive 222, reducing the requirements on the upper fulcrum drive 222 and improving the compactness of the structure. Moreover, the upper hinge 221 can also serve as a support and guide structure, improving the connection strength and rigidity between the side mold grinding roller assembly 21 and the template grinding device body 1, preventing the side mold grinding roller assembly 21 from swaying or displacing relative to the template grinding device body 1 at angles and directions other than the grinding direction, thus improving the stability of the structure. The upper fulcrum drive 222 and the lower fulcrum drive 223 can be linear movement devices with telescopic output rods, such as cylinders, hydraulic cylinders, or electric cylinders, or they can be rotary drive devices, which can be selected according to actual needs.

[0028] In one embodiment, the upper hinge member 221 includes a hinge plate I 2211 and a connecting plate 2212 connected to each other. The connecting plate 2212 is disposed on one side of the hinge plate I 2211. The two ends of the hinge plate I 2211 are provided with hinge portions. One hinge portion is used to hinge with the side mold grinding roller assembly 21, and the other hinge portion is used to hinge with the template grinding device body 1. The slide groove 2213 is disposed on the connecting plate 2212. The plate plane of the hinge plate I 2211 is coplanar with the plane where the two hinge axes of the hinge plate I 2211 are located. Optionally, the plate plane of the connecting plate 2212 is perpendicular to the plate plane of the hinge plate I 2211 to facilitate the arrangement of the slide groove 2213.

[0029] In one embodiment, the body 2221 of the upper fulcrum drive 222 (when the upper fulcrum drive 222 is a cylinder, hydraulic cylinder or electric cylinder, the body 2221 is the cylinder body and the output end is the piston rod) is vertically fixed inside the template grinding device body 1. The pin 2222 on the output end of the upper fulcrum drive 222 moves along the vertical direction of the template grinding device body 1. This arrangement facilitates the compact and reliable installation of the upper fulcrum drive 222 on the template grinding device body 1, ensuring the overall compactness of the structure and thus controlling the size of the entire structure.

[0030] In one embodiment, one end of the lower fulcrum drive member 223 is hinged to the bottom of the template grinding device body 1. In an embodiment where two sets of the side mold grinding roller assembly 21 and the position adjustment assembly 22 are symmetrically arranged along the middle surface of the template grinding device body 1 in the width direction, the two sets of corresponding lower fulcrum drive members 223 are arranged crosswise to save the installation space of the two sets of lower fulcrum drive members 223 and ensure the compactness of the device.

[0031] In one embodiment, the position adjustment component 22 further includes a lower hinge 224, one end of which is hinged to the side mold grinding roller assembly 21 and the other end is hinged to the template grinding device body 1, for limiting the lateral swing of the side mold grinding roller assembly 21; the setting of the lower hinge 224 can balance the lateral disturbance of the side mold grinding roller assembly 21 during grinding, and further limit the displacement and shaking of the side mold grinding roller assembly 21 in other directions besides the grinding direction, thereby improving the stability of the device.

The multiple hinge axes of the lower hinge member 224 are parallel to the two hinge axes of the lower fulcrum drive member 223. That is, in this embodiment, the lower hinge member 224 does not affect the movement of the lower fulcrum drive member 223, but is only used to limit the lateral disturbance of the side mold grinding roller assembly 21. In a preferred embodiment, only two hinge plates II 2241 are provided, and the hinge plates II 2241 have a plate-like structure. One end of the two hinge plates II 2241 is hinged to each other, the other end of one hinge plate II 2241 is hinged to the side mold grinding roller assembly 21, and the other end of the other hinge plate II 2241 is hinged to the template grinding device body 1.

In a preferred embodiment, the side mold grinding structure of the template grinding device also includes a lateral distance sensor 23 and a bottom distance sensor 24. The lateral distance sensor 23 is set on the side of the mounting plate 211 in the side mold grinding roller assembly 21 and faces outward, and is used to detect the distance between the side mold grinding roller assembly 21 and the side mold 102. The bottom distance sensor 24 is set at the lower end of the mounting plate 211 in the side mold grinding roller assembly 21 and faces the bottom mold, so as to monitor the distance between the grinding roller 212 and the side mold 102 and the bottom mold 101.

In the bottom mold grinding structure 5 of the template grinding device of the present invention, the bottom mold grinding component 52 is hinged to the bottom mold support 51, so that the bottom mold grinding component 52 can rotate freely relative to the bottom mold support 51. Optionally, by extending the distance between the bottom mold grinding component 52 and the hinge point, the swing arc of the bottom mold grinding component 52 relative to the bottom mold support 51 is increased, thereby increasing the adjustment range of the bottom mold grinding component 52. An opening and closing adjustment structure and a horizontal angle adjustment mechanism are respectively provided on the bottom mold support 51. The bottom mold grinding assembly 52 is adjusted in various ways through the opening and closing adjustment structure and the horizontal angle adjustment mechanism. The grinding width of the bottom mold is adjusted by adjusting the movement of the bottom mold grinding assembly 52. ​​The grinding pressure of the bottom mold grinding assembly 52 on the bottom mold is adjusted by the opening and closing adjustment structure, thereby adjusting the grinding efficiency. The bottom mold grinding component 52 can be adjusted in various ways using the opening and closing adjustment structure and the horizontal angle adjustment mechanism. Specifically, for example, the grinding area and width of the bottom mold grinding component 52 can be extended by adjusting the opening and closing of the bottom mold grinding component 52 relative to the bottom mold support 51; the grinding area and width of the bottom mold grinding component 52 can be extended by rotating the bottom mold support 51; the grinding width of the bottom mold can be adjusted by adjusting the tilt angle of the bottom mold grinding component 52 relative to the bottom mold; or the grinding area and width of the bottom mold grinding component 52 can be extended by simultaneously adjusting the opening and closing of the bottom mold grinding component 52 relative to the bottom mold support 51 and rotating the bottom mold support 51. Different adjustment methods can bring different adjustment efficiencies, grinding area ranges, and grinding widths, etc. One or more adjustment methods can be used as the primary adjustment method, while other adjustment methods are used as auxiliary adjustment methods or for fine-tuning. This allows for adaptation to different environmental scenarios and is applicable to the grinding of formwork for different types of box girders 10. This improves the adaptability of the bottom formwork grinding structure 5 and even the entire formwork grinding device, thereby reducing grinding costs. It is particularly suitable for grinding the bottom formwork of box girders 10 with variable cross-sections or in complex working conditions where there are multiple sizes or types of box girders 10.

A first set of bottom mold grinding rollers 522 are fixedly connected to the first rotating shaft, and a second set of bottom mold grinding rollers 522 are fixedly connected to the second rotating shaft. The use of multiple bearing seats ensures the structural stability of the bottom mold grinding rollers 522 during grinding, guaranteeing balanced grinding force. This satisfies the grinding requirements of the bottom mold while avoiding problems such as uneven grinding stability and force caused by the bottom mold grinding rollers 522 extending and cantilevering. Optionally, the drive device 523 uses a rotary cylinder, which adaptively adjusts the force based on the compressibility of the gas in the rotary cylinder. This improves the grinding effect while preventing excessive grinding and wear on the bottom mold.

The adjustment method can adopt a combination structure of slider, groove, and pin, or a combination structure of perforated plate and pin, or a cylinder, hydraulic cylinder, etc. Optionally, the telescopic adjustment member 53 is a cylinder or hydraulic cylinder.

[0054] like Figure 20 , Figure 21 , Figure 24 and Figure 25 As shown, in this embodiment, the horizontal angle adjustment mechanism is fixedly mounted on the bottom mold support 51 to drive the bottom mold support to rotate horizontally. The horizontal angle adjustment mechanism controls the bottom mold support 51 to rotate horizontally, thereby driving the bottom mold grinding assembly 52 to rotate, thus realizing the control of the bottom mold grinding area and grinding width; in addition, combined with the opening and closing adjustment structure, it can realize the comprehensive adjustment of the bottom mold grinding area and grinding width, which can not only expand the adjustment range, but also realize initial adjustment and fine adjustment, achieving precise adjustment, and improving both adjustment efficiency and accuracy.

[0055] like Figure 19 , Figure 21 , Figure 24 and Figure 25As shown, in this embodiment, the horizontal angle adjustment mechanism includes a first adjustment plate 54 and a second adjustment plate 58. The first adjustment plate 54 is connected to the bottom mold support 51, and the second adjustment plate 58 is connected to the template grinding device body. The first adjustment plate 54 and the second adjustment plate 58 are arranged in an overlapping manner and are bolted together through the hole fit between the first adjustment plate 54 and the second adjustment plate 58 to achieve adjustment of different horizontal angles. The first adjustment plate 54 and the second adjustment plate 58 are respectively provided with multiple sets of elongated holes 541 or multiple sets of arc-shaped holes arranged symmetrically in a central manner. Bolts are bolted together through the hole fit between the elongated holes 541 or between the elongated holes 541 and the arc-shaped holes to achieve adjustment of different horizontal angles. Optionally, the horizontal angle adjustment mechanism can also adopt a turntable, dial-type structure, or a planar bearing-type structure. Optionally, at least one of the following can be provided on the first adjusting plate 54 and the second adjusting plate 58: a round hole, an elongated hole 541, and an arc-shaped hole; the arrangement of the holes can be arranged along a straight line, along an arc, in an array, etc.; the arrangement of the holes can be regular or irregular; the position and type of the holes on the first adjusting plate 54 and the second adjusting plate 58 can be the same or different.

[0056] like Figure 19 , Figure 21 , Figure 24 and Figure 25 As shown, in this embodiment, the first adjusting plate 54 and the second adjusting plate 58 are configured in a one-to-one correspondence to form a group structure. Multiple groups of these structures are arranged symmetrically between the bottom mold support 51 and the template grinding device body. Synchronous adjustment via these multiple groups improves the stability of the adjustment.

[0057] like Figure 19 As shown in this embodiment, a tension spring 55 is also provided between the bottom mold grinding assembly 52 and the bottom mold support 51. The first end of the tension spring 55 is connected to the transport fixing plate 56, and the second end of the tension spring 55 is connected to the ear plate of the bottom mold grinding assembly 52. ​​The tension spring 55 plays a dual role of tensioning and buffering force, which can reduce vibration during grinding and play a vibration damping role. The transport fixing plate 56 can also play a role in hoisting and transporting and assisting in disassembly and assembly.

[0058] like Figure 22 and Figure 23As shown, in this embodiment, a bottom mold anti-collision mechanism 57 is provided on the bottom mold support 51. The bottom mold anti-collision mechanism 57 is arranged facing the bottom mold and is used to prevent the bottom mold grinding assembly 52 from being over-adjusted and thus colliding and abrading with the bottom mold. When the bottom mold has a protruding structure, the bottom mold anti-collision mechanism 57 can adaptively support itself on the protruding structure, thereby raising the bottom mold grinding assembly 52 and avoiding rigid damage to the bottom mold grinding assembly 52. ​​When the bottom mold grinding assembly 52 is over-adjusted by the opening and closing adjustment structure, the bottom mold anti-collision mechanism 57 will preferentially contact the bottom mold, thereby preventing the part of the bottom mold grinding assembly 52 other than the bottom mold grinding roller 522 from contacting the bottom mold and causing damage.

[0059] In implementation, a bottom mold grinding structure 5 is provided. First, the width of the bottom mold 101 is adjusted. The grinding angle and grinding width of the bottom mold grinding component 52 are adjusted by the opening and closing adjustment structure and the horizontal angle adjustment mechanism, so as to quickly and accurately match the width of the bottom mold 101. More specifically, the adjustment process is to adjust the first adjustment plate 54 horizontally to a suitable angle, and then adjust the bottom mold grinding component 52 to achieve a fine adjustment of the width by adjusting the telescopic adjustment component 53 until the grinding width of the bottom mold grinding component 52 is fully covered and matches the width of the bottom mold 101. At this time, the bottom mold grinding component 52 is driven to operate, and the template grinding device moves along the longitudinal direction of the bottom mold 101 of the box girder 10, thereby realizing the grinding operation of the bottom mold 101 of the box girder 10.
