[0035] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0036] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0037] Please refer to Figures 1 to 3 This embodiment provides a grinding and repair device for an arc surface 100, including a frame 200. A set of slide rails 300 is provided on the frame 200. A fixed frame 400 is provided at one end of the slide rail 300 and a movable frame 500 that can slide along the slide rail 300 is provided at the other end. A set of front-facing wheels for moving along the arc surface 100 are provided on both the fixed frame 400 and the movable frame 500.

[0038] A grinding motor 710 is mounted on the fixed frame 400, and a grinding disc 720 is mounted on the output shaft of the grinding motor 710.

[0039] The frame 200 is also connected to a reverse-side traveling wheel for moving along the reverse side of the arc surface 100. The reverse-side traveling wheel is connected to the frame 200 via a connecting assembly 900.

[0040] In the arc surface 100 grinding and repair device provided in this embodiment, a slide rail 300 is provided on the frame 200. A fixed frame 400 and a movable frame 500 are respectively provided at both ends of the slide rail 300. By adjusting the distance between the movable frame 500 and the fixed frame 400, the distance between the two sets of front walking wheels can be adjusted. On the one hand, it can adapt to arc surfaces of different widths. On the other hand, depending on the location to be repaired, the position of the grinding disc 720 installed on the grinding motor 710 can also be adjusted to adapt to the location to be repaired.

[0041] The frame 200 is also connected to a reverse traveling wheel. The front traveling wheel and the reverse traveling wheel move along the front and back sides of the arc surface 100 respectively, "clamping" the arc surface 100 to be ground and repaired in the middle, which can ensure that the arc of the repaired arc surface 100 meets the requirements.

[0042] It should be noted that, in this embodiment, before grinding and repairing the arc surface 100, the distance between the grinding surface of the grinding disc 720 (i.e., the contact point between the grinding disc 720 and the arc surface 100) and the plane containing the two sets of front-facing wheels needs to be adjusted according to the curvature of the arc surface 100. Generally, under the same conditions, if the radius of the arc surface 100 is larger, the distance between the grinding surface of the grinding disc 720 and the plane containing the two sets of front-facing wheels will be relatively smaller; if the radius of the arc surface 100 is smaller, the distance between the grinding surface of the grinding disc 720 and the plane containing the two sets of front-facing wheels will be relatively larger. Typically, different sizes of grinding discs 720 can be selected while keeping the axis position of the grinding disc 720 unchanged, or the position of the axis of the grinding disc 720 can be adjusted while keeping the size of the grinding disc 720 inconvenient. The specific choice can be made according to the needs.

[0043] In an optional embodiment, the movable frame 500 adjustment device is also included, which includes an adjustment screw 800 and two fixing ears, one of which is fixed on the fixed frame 400 and the other of which is fixed on the movable frame 500.

[0044] One of the fixed ears is provided with a movable mounting hole, and the other fixed ear is provided with a threaded hole. The adjusting screw 800 passes through the movable mounting hole and the threaded hole in sequence. The adjusting screw 800 is movably connected to the movable mounting hole and threadedly connected to the threaded hole.

[0045] In this embodiment, the distance between the movable frame 500 and the fixed frame 400 can be adjusted by an adjusting screw. Specifically, one end of the adjusting screw can pass through a movable mounting hole and a limit structure is provided at the end of the adjusting screw, allowing the adjusting screw to rotate freely within the movable mounting hole. The surface of the adjusting screw can also be threaded to facilitate threaded connection between the adjusting screw and the threaded hole. Thus, during the rotation of the adjusting screw, the relative position of the fixed lug with the movable mounting hole and the adjusting screw remains unchanged, but the fixed lug with the threaded hole will move along the adjusting screw, thereby adjusting the distance between the fixed frame 400 and the movable frame 500, adjusting the position of the front traveling wheel, or adapting the grinding and repair position. Furthermore, to facilitate the rotation of the adjusting screw 800, a handwheel can be provided at one end of the adjusting screw.

[0046] Specifically, in this embodiment, the fixed ear corresponding to the fixed frame 400 is provided with a threaded hole, and the fixed ear corresponding to the movable frame 500 is provided with a movable mounting hole. In some other embodiments, the fixed ear corresponding to the movable frame 500 may also be provided with a threaded hole, and the fixed ear corresponding to the fixed frame 400 may be provided with a movable mounting hole.

[0047] In an optional embodiment, the reverse traveling wheel includes a reverse positioning wheel 630, and the front traveling wheel includes a set of front positioning wheels 610 and a set of front rolling wheels 620. The front positioning wheels 610 and the reverse positioning wheels 630 cooperate to guide the movement path of the arc surface 100 grinding and repair device, which is beneficial for each traveling wheel of the arc surface 100 grinding and repair device to move on the same circumference and prevent the arc surface 100 grinding and repair device from deviating from the preset direction.

[0048] In an optional embodiment, the plane where the front positioning wheel 610 is located and the plane where the back positioning wheel 630 is located are respectively located on both sides of the plane where the front rolling wheel 620 is located. The two sets of positioning wheels located on both sides of the front rolling wheel 620 can prevent the arc surface 100 grinding and repair device from deviating from the preset path along the axial direction of the arc surface 100.

[0049] In this embodiment, a set of front positioning wheels 610 are provided on the movable frame 500, and a set of front rolling wheels 620 are provided on the fixed frame 400. The front positioning wheels 610 and the back positioning wheels 630 respectively prevent the arc surface 100 grinding and repair device from shifting to both ends of the arc surface 100 axis.

[0050] In an optional embodiment, the front positioning wheel 610 and / or the back positioning wheel 630 include a rolling part 640 and a stopping part 650 arranged coaxially. The diameter of the stopping part 650 is larger than the diameter of the rolling part 640, and the stopping part 650 has a stopping surface on the side near the rolling part 640.

[0051] When the front positioning wheel 610 and / or the back positioning wheel 630 are positioned, the rolling part 640 rolls along the arc surface 100 near the edge, and the stopping surface of the stopping part 650 is close to the end face of the arc surface 100, generating sliding friction between them. The stopping part 650 can prevent the positioning wheel from deviating to the side where the rolling part 640 is located.

[0052] In an optional embodiment, the connecting assembly 900 includes a fixing rod 910, a thickness adjusting rod 920, and a width adjusting rod 930. One end of the fixing rod 910 is fixed to the frame 200, and the other end is connected to the thickness adjusting rod 920. The thickness adjusting rod 920 is provided with a thickness adjusting sleeve 921 that can move up and down along the thickness adjusting rod 920. The width adjusting rod 930 is provided with a width adjusting sleeve 931 that can move along the width adjusting rod 930. The thickness adjusting sleeve 921 and the width adjusting sleeve 931 are fixedly connected. The reverse positioning wheel 630 is mounted on the width adjusting rod 930.

[0053] In this embodiment, the connecting assembly 900 includes a fixing rod 910, a thickness adjusting rod 920, and a width adjusting rod 930. Both the fixing rod 910 and the width adjusting rod 930 are arranged along the axial direction of the arc surface 100. The thickness adjusting rod 920 is perpendicular to the fixing rod 910. The fixing rod 910 is used to fix the thickness adjusting rod 920 to the frame 200. In this embodiment, a mounting beam is provided on the frame 200. One end of the fixing rod 910 is fixed to the mounting beam, and the other end is fixed to the thickness adjusting rod 920. By adjusting the distance between the thickness adjusting sleeve 921 and the fixing rod 910, arc surfaces 100 of different thicknesses can be accommodated. By adjusting the distance between the width adjusting sleeve 931 and the reverse positioning wheel 630, arc surfaces 100 of different widths can be accommodated.

[0054] In an optional embodiment, a first positioning block 922 is provided on the thickness adjusting rod 920 on the side of the thickness adjusting sleeve 921 away from the fixed rod 910, and a compression spring 923 is provided between the first positioning block 922 and the thickness adjusting sleeve 921.

[0055] The first positioning block 922 can be fixedly installed on the thickness adjusting rod 920, or it can be connected to the thickness adjusting rod 920 by threads. In this embodiment, the first positioning block 922 and the thickness adjusting rod 920 are connected by threads. Before the arc surface 100 grinding and repair device is started, the position of the first positioning block 922 on the thickness adjusting rod 920 is initially adjusted. Under the support of the first positioning block 922, the compression spring 923 can press the thickness adjusting sleeve 921 towards the arc surface 100, so that the reverse positioning wheel 630 and the front positioning wheel 610 can roll along the reverse and front sides of the arc surface 100, respectively.

[0056] In an optional embodiment, a second positioning block 932 is provided on the side of the width adjusting sleeve 931 away from the reverse traveling wheel, and the second positioning block 932 is threadedly connected to the width adjusting rod 930.

[0057] The second positioning block 932 and the width adjusting rod 930 are threadedly connected. By rotating the second positioning block 932, the distance between the width adjusting sleeve 931 and the reverse traveling wheel can be adjusted to adapt to the arc surface 100 of different widths.

[0058] In this embodiment, the first positioning block 922 and the second positioning block 932 can be nuts. In some other embodiments, they can also be other structures that can move and be positioned along the corresponding adjusting rod.

[0059] In an optional embodiment, a slider capable of sliding along the slide rail 300 is provided on the slide rail 300, the fixing frame 400 is fixed to the slider, and a swing motor 730 capable of driving the slider to reciprocate along the slide rail 300 is fixed on the fixing frame 400.

[0060] Normally, the grinding position of the grinding disc 720 can be adjusted by adjusting the distance between the fixed frame 400 and the movable frame 500. However, in this embodiment, the distance between the fixed frame 400 and the movable frame 500 is adjusted manually, which is inconvenient to adjust during the grinding process. Therefore, in this embodiment, the oscillating motor 730 drives the slider to slide back and forth along the slide rail 300 so that the grinding disc 720 can move within a small range and expand the area of ​​the grinding region.

[0061] Specifically, in some embodiments, the output end of the swing motor 730 can be provided with a swing linkage. The swing linkage rotates around the output shaft of the swing motor 730. The other end of the swing linkage is movably connected to a connecting rod. The end of the connecting rod away from the swing linkage is movably connected to the slide rail 300, so that the swing motor 730 can drive the slider to slide back and forth along the slide rail 300 during rotation, that is, to realize the purpose of the grinding disc 720 sliding back and forth along the slide rail 300 to expand the area of ​​the grinding region.

[0062] In an optional embodiment, the fixed frame 400 is provided with a walking drive motor 600 capable of driving the front walking wheel. The drive motor drives the grinding disc 720 to move circumferentially, and the swing motor 730 drives the grinding disc 720 to move axially, so as to grind and repair the defective area.

[0063] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
