Description

Technical Field

[0001] This utility model belongs to the field of manhole cover processing technology, and in particular relates to a device for trimming the edge of a long strip manhole cover. Background Technology

[0002] Manhole covers are typically used to cover roads or deep wells to prevent people or objects from falling in. They also help keep the well clean and prevent gas leaks. They are usually made of materials such as iron, steel, concrete, or plastic, with the choice of material depending on factors such as the purpose of the well, traffic flow, groundwater level, and budget.

[0003] During the processing of long, rectangular manhole covers, burrs may appear on the edges due to manufacturing defects. To make the product surface smoother and flatter, improve its overall aesthetics and quality, reduce the risk of scratches during installation, and ensure that the product quality meets standards, grinding equipment is needed to grind the edges of the manhole cover. When grinding the manhole cover, clamps are required to hold and fix it in place. Because it is impossible to grind all four sides of the manhole cover at the same time, the installation position of the manhole cover needs to be adjusted multiple times to grind different parts of the edge. The process of repeatedly installing the manhole cover is tedious, time-consuming, and reduces work efficiency. Utility Model Content
