By using the electric telescopic rod in conjunction with the snap-fit ​​support frame, the rotating disk 21 can be snap-fitted and supported after rotation, thereby further improving the overall stability of this part.

A cutting motor 25 is fixedly installed on the disk body 23 through a support frame 24, and a cutting disc 26 is fixedly installed on the driving end of the cutting motor 25. When the cutting motor 25 is working, it can drive the cutting disc 26 to rotate at a high speed, so as to perform linear cutting when required; a motor groove is opened on the lower surface of the disk body 27, and a cutting motor 28 is fixedly installed in the motor groove. A reinforcing disc 29 is installed on the driving end of the cutting motor 28 through a one-way bearing 5.

A moving block 37 is threadedly installed on each reciprocating screw 36, and each moving block 37 is fixedly connected to the corresponding square rod 32 through two moving frames 39; at the same time, a slide groove 41 required for the movement of the square rod 32 can be opened on the lower surface of the disk body 27, and the side wall of the square rod 32 is in contact with the side wall of the slide groove 41, so that the disk body 27 can drive the square rod 32 to rotate more stably when rotating.

[0042] The one-way bearing five may not be provided, so that the cutting motor two 28 can directly drive the square rod 32 to rotate. However, in this case, the gear ring 38 cannot be directly provided on the driving end of the cutting motor two 28. A shaft rod is provided below the driving end of the cutting motor two 28 through the cooperation of the reduction gear, and then the gear ring 38 is provided on the shaft rod to meet the use requirements. It will not be elaborated here.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0044] In the present invention, firstly, strip cutting or circular cutting is selected according to the shape of the crack to be repaired, and the required repair material can be prepared in the mixing drum 9 during the cutting process;

[0045] Preparation of repair materials: Pour the required raw materials into the mixing drum 9, and then turn on the mixing motor 3. The mixing motor 3 will drive the installation shaft 6 to rotate through the transmission structure 7 and the cooperation of the rotating shaft 5. At this time, the one-way bearing will rotate, and the one-way bearing will drive the installation ring 13 to rotate through the connecting rod 12. The rotation of the installation ring 13 will drive the stirring rod 14 to rotate, thereby achieving a mixing and preparation effect on the materials. For example, when the filling material is cement, the required water and cement powder are mixed to prepare cement slurry. Then, when it is needed, the installation shaft 6 is driven to rotate in the opposite direction through the mixing motor 3. At this time, the conveying screw 15 is in the lowest position (the initial state is set to the lowest, and the installation shaft 6 rotates an integer number of circles each time). At this time, the conveying screw 15 will be driven to rotate under the action of the transmission belt, and the valve on the discharge pipe 11 can be opened to inject the repair material;

[0046] Circular cutting: firstly, the position of the square rod 32 is adjusted according to the required cutting size, and then the cutting motor 28 is turned on. The cutting motor 28 drives the gear ring 38 to rotate through the cooperation between the driving end and the one-way bearing 4. The gear ring 38 rotates through the cooperation with the gear to drive the reciprocating screw 36 to rotate. The reciprocating screw 36 rotates to drive the moving block 37 to reciprocate. During the reciprocating movement, the moving block 37 drives the corresponding square rod 32 to move together through the moving frame 39, thereby adjusting the linear distance between the square rod 32 and the driving end of the cutting motor 28, so as to adjust the position of the square rod 32, which is convenient for circular cutting of different diameters; at this time, the reinforcing plate 29 is driven to rotate in the opposite direction by the cutting motor 28, and the reinforcing plate 29 rotates through the fixed rod 30 and the rotating ring 31 to drive the square rod 32 to rotate together, and the square rod 32 rotates to drive the cutting blade 33 to rotate, thereby completing the required cutting operation, and in the cutting process, the cooperation of the hydraulic rod 22 can achieve different degrees of cutting requirements;

[0047] Strip cutting: First, the rotating motor 20 is used to control the rotating disk 21 to rotate 180°. At this time, the cutting disc 26 rotates to the lower position, and then the cutting motor 25 is turned on to start cutting. During operation, the cutting depth of the cutting disc 26 can also be controlled by the corresponding hydraulic rod 22.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
