[0002] A manhole cover is an item used to cover a deep well on a road or in a home to prevent people or objects from falling. It can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers according to the material. It is generally divided into round manhole covers and square manhole covers. In urban road administration, round manhole covers are generally used.

[0003] At present, after the stainless steel manhole cover is cast, an elliptical water outlet hole needs to be opened on the manhole cover to facilitate the passage of water. However, the existing hole cutting method can only fix one manhole cover at a time. After processing, it needs to be disassembled before the next manhole cover to be processed can be installed. This processing method is inefficient and the operation steps are cumbersome. Utility Model Content

[0026] The effect achieved by the entire embodiment 1 is that when using this device, the manhole cover body 9 is first placed inside the conveying trough 2, and is transported to the bottom of the fixed frame 4 under the transmission of two conveyor belts 3. During the transportation process, the guide wheel 8 installed inside the fixed frame 7 is pressed and guided to prevent the manhole cover body 9 from shaking. At the same time, after the transportation is stopped when it is transported to the bottom of the fixed frame 4, the manhole cover body 9 can be pressed and limited by the pressing of the guide wheel 8, which is convenient for subsequent processing using the laser cutter 13.

[0027] Example 2, as Figure 1-4As shown, the outer surface of the guide wheel 8 is in contact with the top of the manhole cover body 9, and a fixing frame 4 is installed on the top of the conveying platform 1.

During the transportation process, the guide wheel 8 installed inside the fixed frame 7 is pressed and guided to prevent the manhole cover body 9 from shaking. At the same time, after the transportation is stopped below the fixed frame 4, the guide wheel 8 presses the manhole cover body 9 to tighten it and limit it, which is convenient for subsequent processing using the laser cutter 13. When the laser cutter 13 is processing, the motor 15 is started and the rotation of the motor 15 drives the manhole cover body 9 to rotate. The driving gear 16 rotates, thereby driving the gear ring 10 to rotate. When the gear ring 10 rotates, it drives the laser cutter 13 to move, which is convenient for adjusting the cutting position of the laser cutter 13. When installing the gear ring 10, the bottom of the limiting nail 17 extends outward, thereby lifting the gear ring 10 upward so that it slides and fits with the bottom of the fixed column 6, and the fixed column 6 is installed on the electric slide rail 5. Its position can be changed by the electric slide rail 5. The rotation of the gear ring 10 can adjust the position of the plane area of ​​the laser cutter 13.
