Description

Technical Field

[0001] This application relates to the field of road surface cutting technology, and in particular to a road surface pothole trimming device. Background Technology

[0002] During emergency repairs of airport runways, potholes often have irregular edges, and directly filling them can lead to poor bonding between the old and new concrete, uneven stress distribution at the pothole's edge, and potential secondary damage after repair. Therefore, before filling potholes with concrete, the edges of the potholes need to be trimmed.

[0003] When trimming potholes, the process typically begins by marking the pothole's outline to create a regular square shape. Then, a trimming device is used to cut the pavement along this square outline. The size of potholes on airport runways varies considerably, and the depth of damage differs depending on the size. Generally, larger potholes have greater depths of damage, necessitating precise control of the cutting depth. Furthermore, airport runway surface repairs are time-sensitive, requiring speed to avoid hindering aircraft takeoffs and landings and causing flight delays. During cutting operations, deeper cuts take longer, further necessitating accurate control of the cutting depth.

[0004] In summary, there is a need for a road surface pothole trimming device that can control the cutting depth. Utility Model Content

[0026] Example Reference Figure 1 As shown, this embodiment provides a road surface pothole trimming device, including a frame 110, a movable base 120, a positioning post 130, a cutting guide wheel 140, a drive motor 150, and a measuring rod 160. A handrail 111 is provided on one side of the frame 110 to facilitate the operator in moving the trimming device and cutting according to the marked contour. A guide post 112 and moving wheels 113 are provided at the bottom of the frame 110, with the guide post 112 extending from the bottom of the frame 110 towards the road surface.

[0027] The movable base 120 is movably connected to the guide post 112, which guides the movable base 120 to move vertically. A first elastic element 121 is provided between the movable base 120 and the frame 110, and the first elastic element 121 has elastic potential energy to drive the movable base 120 closer to the frame 110. The positioning post 130 is threadedly connected to the frame 110 and abuts against the movable base 120. The height of the positioning post 130 can be adjusted by rotating it, thereby limiting the height of the movable base 120 under the cooperation of the first elastic element 121.

[0028] Reference Figure 2 As shown, the cutting guide wheel 140 is rotatably mounted on the movable base 120 and located on the side of the frame 110 away from the handrail 111; the drive motor 150 is mounted on the movable base 120 and is connected to the cutting guide wheel 140 for transmission. The drive motor 150 drives the cutting guide wheel 140 to rotate, thereby cutting the road surface, while the edge trimming device moves along the marked outline to cut out a square outline.

[0029] The measuring rod 160 is movably mounted vertically on the movable base 120 and located on the side of the frame 110 near the handrail 111. One end of the frame 110 passes through the movable base 120 and abuts against the road surface. A second elastic element 161 is sleeved on the measuring rod 160, and the second elastic element 161 has elastic potential energy to drive the measuring rod 160 toward the road surface. When the height of the cutting guide wheel 140 is adjusted by adjusting the height of the movable base 120, the measuring rod 160 abuts against the road surface and extends accordingly, making it convenient for the operator on the handrail 111 side to quickly read the cutting depth.

[0030] The road surface pothole trimming device provided in this embodiment can control the cutting depth of the cutting guide wheel 140 through the cooperation of the positioning post 130 and the first elastic member 121. Since the cutting guide wheel 140 moves with the movable base 120, a measuring rod 160 is set on the side of the movable base 120 near the handrail 111, so that the operator can easily observe the cutting depth of the cutting guide wheel 140 when holding the handrail 111 and pushing the trimming device to move.

[0031] Specifically, the bottom of the measuring rod 160 is provided with a pressure plate 162, which is aligned with the cutting guide wheel 140, such that the extending direction of the pressure plate 162 is the same as the forward direction of the cutting guide wheel 140. The operator can judge whether the cutting guide wheel 140 moves according to the scribed contour by observing whether the pressure plate 162 is aligned with the cut contour, which facilitates observation and ensures the accuracy of the cutting contour.

[0032] Specifically, a small ball is rolled at the bottom of the pressure plate 162 to reduce the pressure between the pressure plate 162 and the ground, allowing the edge trimming device to move smoothly.

[0033] Specifically, the measuring rod 160 is equipped with scale lines, and the cutting depth is determined by reading data from the scale lines. Specifically, the position where the measuring rod 160 intersects with the movable base 120 when the cutting guide wheel 140 is in contact with the road surface can be set as the zero position.

[0034] Specifically, the movable base 120 is provided with an extension 123 extending toward the side where the handrail 111 is located. The extension 123 has a through hole, and the measuring rod 160 extends through the through hole toward the side where the road surface is located. By setting the measuring rod 160 on the side of the handrail 111, it is convenient for the operator to observe the cutting depth and whether the cutting trajectory has deviated when pushing the edge trimming device.

[0035] Specifically, continue to refer to Figure 1 As shown, the guide post 112 passes through the movable base 120 and is connected to a limiting nut 114. The limiting nut 114 can restrict the position of the movable base 120. After adjusting the positioning post 130 to achieve the required depth of the cutting guide wheel 140, the limiting nut 114 can be tightened so that the top of the movable base 120 abuts against the positioning post 130 and the bottom abuts against the limiting nut 114, thereby completely limiting the vertical position of the movable base 120 and preventing vertical swaying of the movable base 120 during cutting or transportation.

[0036] Specifically, continue to refer to Figure 2 As shown, the movable base 120 has a clamping groove on the side away from the armrest 111, and bearing seats 122 are respectively provided on both sides of the clamping groove. The cutting guide wheel 140 extends into the clamping groove and is connected to the two bearing seats 122 respectively. The cutting guide wheel 140 is engaged with the drive motor 150 through gear transmission.

[0037] Specifically, refer to Figure 3 As shown, the frame 110 includes a housing with an opening at the bottom and a connecting lug 115 connected inside the housing. The positioning post 130 passes through the housing and is threadedly connected to the connecting lug 115. The housing protects the drive motor 150.

[0038] Specifically, the four corners of the bottom of the housing are provided with reinforcing parts 116, and the guide post 112 is connected to the bottom of the reinforcing post.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
