[0039] A road crack repairing device comprises a main body 1, a winding part, an unwinding part 4, a fixing column 9, and a first pressing roller 6;

[0040] The unwinding part 4 and the rewinding part are rotatably arranged at one end of the main body 1; the unwinding part 4 is used for unwinding the repair material; the rewinding part is used for rewinding the protective film of the repair material; the first pressing roller 6 is rotatably arranged at the bottom of the main body 1, and is used for pressing the unwinding repair material to the road crack;

[0041] The repair material is sleeved on the outer circumference of the unwinding part 4, and a support rod 43 is provided in the circumference of the unwinding part 4 for radial sliding; the fixed column 9 is plug-in connected to the unwinding part 4 along the rotation axis direction of the unwinding part 4, and is used to push the support rod 43 to slide radially toward the outer circumference and support the repair material.

[0042] In a specific embodiment of the present application, the unwinding portion 4 is a cylindrical structure that matches the internal shape of the repair material. One end of the unwinding portion 4 is axially connected to the main body 1, and the other end of the unwinding portion 4 is axially provided with a slot 41 for plugging and unplugging with the fixed column 9. The unwinding portion 4 is provided with a plurality of slide grooves 42 at intervals in the circumferential and axial directions, and the support rod 43 is slidably matched with the unwinding portion 4 through the slide grooves 42. When the fixed column 9 is not inserted into the unwinding portion 4, the side of the support rod 43 close to the outer periphery of the unwinding portion 4 is consistent with the height of the outer peripheral plane of the unwinding portion 4, and the side of the support rod 43 close to the slot 41 of the unwinding portion 4 protrudes from the plane of the slot 41 of the unwinding portion 4; when the fixed column 9 is inserted into the unwinding portion 4, the side of the support rod 43 close to the outer periphery of the unwinding portion 4 protrudes from the outer periphery of the unwinding portion 4, and the side of the support rod 43 close to the slot 41 of the unwinding portion 4 is consistent with the plane of the slot 41 of the unwinding portion 4. The plug-in and pull-out cooperation between the fixing column 9 and the unwinding part 4 can not only facilitate the installation of the repair material, but also fix the relative position of the repair material and the unwinding part 4, so as to avoid the repair material and the unwinding part 4 from rotating relative to each other when the unwinding part 4 unwinds the repair material, thereby affecting the quality of the road repair. The first pressing roller 6 is fixedly connected to the bottom of the main body 1 through the connecting frame 5, and the first pressing roller 6 is rotatably connected to the connecting frame 5. The repair material is asphalt tape.

[0043] In the specific use of the device, firstly, the asphalt tape is sleeved on the unwinding part 4, and then the fixing column 9 is inserted to tighten and fix the asphalt tape, and the end of the asphalt tape is pulled out, and the protective film is torn off and fixed to the reeling part. Along the moving direction of the crack repairing device, the end of the asphalt tape is rolled down from the front side of the first pressure roller 6 and pressed to the road crack, and then the device is pushed to move along the road crack, so that the asphalt tape is continuously unwound under the downward pressure of the first pressure roller 6, and the reeling part continuously reels the protective film, so as to achieve continuous adhesive repair of the road crack.

[0044] A receiving portion 2 is also provided at one end of the main body 1; the receiving portion 2 is used to receive the repair material; the unwinding portion 4 is rotatably disposed in the receiving portion 2;

[0045] A cover plate 7 is detachably provided on the side of the accommodating portion 2, and a fixing column 9 is rotatably connected to the cover plate 7 along the rotation axis direction of the unwinding portion 4;

[0046] A notch is provided at the bottom of the accommodating portion 2 for extending the unrolled repair material.

[0047] In a specific embodiment of the present application, the accommodating portion 2 is a disc structure that matches the external shape of the repair material.

The side of the accommodating portion 2 provided with the accommodating groove 3 is detachably connected to the cover plate 7 by bolts. Specifically, a plurality of screw holes 8 are circumferentially spaced apart on the side surface of the side where the accommodating portion 2 is connected to the cover plate 7, and a plurality of screw holes 8 are also provided at corresponding positions of the cover plate 7. On the one hand, the cover plate 7 is pluggably connected to the unwinding portion 4 by a fixing column 9, and on the other hand, it is detachably connected to the accommodating portion 2 by the combination of bolts and screw holes 8, so as to prevent the repair material from falling off the unwinding portion 4 during use, thereby further improving the stability of the device.

[0048] The shape of the side of the support rod 43 contacting the repair material matches the outer peripheral shape of the unwinding part 4; the side of the support rod 43 contacting the fixed column 9 is inclined toward the rotation axis of the unwinding part 4 along the insertion direction of the fixed column 9.

[0049] In a specific embodiment of the present application, the side of the support rod 43 that contacts the repair material is an arc-shaped plate 44 that matches the outer peripheral shape of the unwinding portion 4, so as to further facilitate the sleeve installation of the repair material; the side of the support rod 43 that contacts the fixed column 9 is inclined toward the rotation axis of the unwinding portion 4 along the insertion direction of the fixed column 9, so as to facilitate the insertion of the fixed column 9 into the slot 41 of the unwinding portion 4.

[0050] A baffle 46 is provided on the periphery of the support rod 43 and the unwinding part 4 for sliding cooperation. A baffle groove 45 is provided at the corresponding positions of the unwinding part 4 and the baffle 46 . A first spring 47 is connected to one side of the baffle 46 close to the periphery of the unwinding part 4 . The first spring 47 is arranged in the baffle groove 45 .

At the same time, a first spring 47 is arranged on one side of the baffle 46 close to the periphery of the unwinding portion 4. The elastic force applied by the first spring 47 to the baffle 46 enables the support rod 43 to automatically reset and maintain its relative position with the unwinding portion 4 unchanged after the fixing column 9 is pulled out of the unwinding portion 4.
