Description

Technical Field

[0001] The utility model relates to the technical field of ground crack repairing, in particular to a ground crack repairing device. Background Art

[0002] Many courtyards or squares in China are paved with asphalt or concrete.

During the repair process, the discharge pipe 9 is driven to move by the adjustment unit, so that the discharge pipe 9 can repair the curved crack, improve the convenience of adjustment, and improve the speed of repair;

[0030] like Figure 1-Figure 8As shown, the adjustment unit includes a first motor 301, a screw rod 302 and an adjustment controller 310. The first motor 301 is installed in the installation slot 7. The screw rod 302 is rotatably installed in the installation slot 7. The end of the screw rod 302 is fixedly connected to the output shaft of the first motor 301.

The lower surface of the mounting plate 305 is installed with a vibrating machine The first motor 301, the first hydraulic cylinder assembly 304 and the camera 306 are used to repair the cracks on the ground. The repair trolley 1 moves to the position on the ground that needs to be repaired, so that the repair trolley 1 is located above the cracks, and the mounting plate 305 is driven to move by the first hydraulic cylinder assembly 304. 305 drives the discharge pipe 9 to move, lowers the height of the discharge pipe 9, and allows the repair material to better enter the crack. During the repair process, the ground crack is photographed by the camera 306, and the picture taken by the camera 306 is displayed by the display screen 311, so that the staff can quickly determine the position of the crack. According to the position and direction of the crack, the first motor 301 is controlled by the adjustment controller 310 to drive the screw rod 302 to rotate, and the screw rod 302 drives the first hydraulic cylinder assembly 304 to move through the movable frame 303. The first hydraulic cylinder assembly 304 drives the discharge pipe 9 to move through the mounting plate 305, and adjusts the position of the discharge pipe 9 so that the discharge pipe 9 moves to the top of the crack, ensuring that the repair material sprayed from the discharge pipe 9 can better enter the crack for repair, reducing the waste of repair material, and the discharge pipe 9 can be adjusted along the direction of the crack, which increases the convenience of adjustment and effectively improves the efficiency and quality of crack repair. After the repair material enters the crack, the repair material is vibrated by the vibration mechanism to increase the flow of the repair material in the crack, so that the repair material can fully fill the crack and ensure the repair effect.

[0031] like Figure 4-Figure 6As shown, the material vibration mechanism on the mounting plate 305 includes a second hydraulic cylinder assembly 307, and the second hydraulic cylinder assembly 307 is mounted on the upper surface of the mounting plate 305.

The heated airflow is ejected through the nozzle 401, thereby blowing out dust and other debris in the cracks on the ground. Since the airflow ejected from the nozzle 401 is a high-temperature airflow, the airflow ejected from the nozzle 401 heats the cracks to a certain extent, increasing the temperature at the cracks, reducing the temperature difference when the repair material and the cracks are in contact, and reducing the curing speed of the repair material in the cracks, so that the repair material can move and fill in the cracks better, thereby improving the quality of crack repair.

[0033] like Figure 1 , Figure 2 , Figure 5 , Figure 7As shown, a stirring unit for stirring ground crack repair material is installed in the barrel 8, and the stirring unit includes a second motor 501 and a main shaft 502. The second motor 501 is installed on the upper surface of the barrel 8, and the main shaft 502 is rotatably installed in the barrel 8.

The heated airflow is ejected through the nozzle 401, thereby blowing out dust and other debris in the cracks on the ground and increasing the temperature at the cracks; at the same time, the dust collection component 601 absorbs the cleaned dust, debris and other debris through the dust collection cover 602;

[0040] like Figure 1-Figure 8 As shown, the first hydraulic cylinder assembly 304 drives the mounting plate 305 to move, and the mounting plate 305 drives the discharge pipe 9 to move, so that the discharge pipe 9 is close to the crack on the ground, and the repair material in the barrel 8 is transported to the discharge pipe 9 through the pumping assembly 10, and the repair material is transported to the crack through the discharge pipe 9 for repair;

[0041] like Figure 1-Figure 8 As shown, during the repair process, the ground cracks are photographed by the camera 306, and the images photographed by the camera 306 are displayed by the display screen 311, so that the staff can quickly determine the position of the cracks.
