Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a composite material manhole cover edge and corner grinding device. Background Art

[0002] Manhole covers are generally round and made of cast metal. They are widely used in green belts, sidewalks, motor vehicle lanes and other areas. After the manhole cover is cast, its surrounding sides need to be polished to ensure that the manhole cover fits the manhole ring.

[0003] In the prior art, the grinding of manhole covers usually requires grinding on both sides, but most grinding devices are unable to flip the manhole covers during the grinding process and need to be flipped manually, which not only increases the labor intensity of the staff, but also seriously affects the grinding efficiency of the manhole covers. Utility Model Content

A fixing groove is opened on the top of the mounting plate, and a second grinding device is fixedly inserted into the inner wall of the fixing groove.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In use, when one side of the manhole cover is polished, the third telescopic rod is first used to drive the mounting block to move toward the middle inside the mounting box, thereby driving the fixing device to move toward the middle and fixing the manhole cover, and then, under the action of the fourth telescopic rod, the fixing block and the fixing device are driven to move upward, thereby driving the manhole cover to move upward. When it moves to a suitable position, the second transmission wheel is driven to rotate by the third motor, and at the same time, under the action of the first transmission wheel, the fixing device and the manhole cover are driven to rotate 180 degrees, and then, under the action of the fourth telescopic rod, the manhole cover is driven back to the inside of the supporting platform, and under the action of the magnetic plate, the manhole cover is fixed, and then, under the action of the third telescopic rod, the fixing device is driven to move to both sides, and finally, the other side of the manhole cover is polished. The manhole cover can be easily turned over by the above structure and method, thereby reducing the labor intensity of the staff and improving the efficiency of manhole cover polishing.

[0014] 2. In use, after the manhole cover is placed, the first telescopic rod drives the fixing column to move inside the slide groove, so that the first grinding device contacts the manhole cover and grinds its edge. Then, the first motor drives the meshing wheel to rotate, thereby driving the mounting plate to move inside the embedded groove and driving the second grinding device to move to a suitable position. Subsequently, the second telescopic rod drives the lifting frame to move downward, so that the second grinding device contacts the manhole cover and grinds it. The above structure and method can grind the top surface and edge of the manhole cover at the same time, which not only further improves the grinding efficiency of the manhole cover, but also greatly improves the practicability of the grinding device.
