[0053] Reference Figure 3The frame 100 is connected to a support frame 400, which is located above the opening 202. A lifting component 102 is connected within the support frame 400. The lifting component 102 uses a support spring, which is vertically positioned and its bottom end is connected to the support frame 400.

The controller receives pressure and tension values ​​and compares them with preset values. When the pressure or tension value is greater than the preset value, the controller reduces the flow rate of the regulating pump 303, thereby reducing the output of the grouting head 302. The controller receives width values ​​and compares them with a preset range. When the width value is less than the minimum value of the preset range, the controller reduces the flow rate of the regulating pump 303, thereby reducing the output of the grouting head 302; when the width value is greater than the maximum value of the preset range, the controller increases the flow rate of the regulating pump 303, thereby increasing the output of the grouting head 302.

[0057] The implementation principle of the grouting device for repairing road cracks according to the embodiment of the application is as follows: when repairing road cracks, the construction personnel place the bottom end of the guide rod 101 in the crack, adjust the pump 303 to deliver the filler in the filler cylinder 300 to the grouting head 302 through the grouting pipe 301, and push the bearing plate 200 along the length direction of the crack with the guide rod 101 as the guide, the crack width detection member 203 detects the crack width, when the crack is wide, the grouting head 302 increases the output filler, when the crack is narrow, the grouting head 302 reduces the output filler, and when the guide rod 101 rotates or rises, the grouting head 302 reduces the output filler, so that the amount of filler output by the grouting head 302 can be controlled according to the required filler for repairing the crack.

[0058] When the crack is wide, the first rotating roller 306 rotates to wind and pull the first rubber belt 304 to make the grouting head 302 rotate and tilt towards the first rotating roller 306, the second rotating roller 308 rotates to wind and pull the second rubber belt 305 to make the grouting head 302 rotate and tilt towards the second rotating roller 308, so that the orientation of the grouting head 302 can be adjusted along the width direction of the crack, and the filler output by the grouting head 302 can be evenly filled into the crack.

[0059] When the crack is narrow, the first rotating roller 306 rotates to wind the first rubber belt 304, the first moving member 311 moves the first rotating roller 306 to the side close to the grouting head 302, at the same time, the second rotating roller 308 rotates to wind the second rubber belt 305, and the second moving member 312 moves the second rotating roller 308 to the side far away from the grouting head 302, so that the stability of the grouting head 302 when outputting the filler can be improved.

[0060] The above are the preferred embodiments of the application, and do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape, principle of the application should be covered in the protection scope of the application.
