Description

Technical Field

[0001] The utility model relates to the technical field of a cutting head repair device for a tunnel boring machine, in particular to an adjusting device for repairing a cutting head for a tunnel boring machine. Background Art

[0002] Roadheaders are widely used in underground space construction fields such as coal mine tunnels, mountain tunnels, and subway tunnels. At present, most domestic cutting heads are imitations of foreign products, and no customized design research on cutting heads has been carried out for different cutting media, resulting in poor adaptability of the cutting heads, inability to effectively break through complex geology, and generally low operating efficiency. Especially in mudstone working conditions, the cut mudstone medium is easily adhered to the surface of the cutting head when it encounters water, forming a "big mud ball", increasing the contact area between the cutting head and the medium, resulting in increased operating resistance of the cutting head and a serious decrease in operating efficiency.

[0003] The existing tunnel boring machine cutting head needs to frequently repair and replace the cutting teeth and tooth holders. The traditional maintenance method is mostly to directly place the cutting head on the clamp. During use, although the clamp can be rotated, in actual use, since the cutting teeth and tooth holders are distributed more on the cutting head, and each is set at a different angle to the outer surface of the cutting head, during actual maintenance and replacement, it is often necessary to adjust different angles so that the maintenance personnel have a better angle state. Simply rotating it is difficult to meet the maintenance needs of different positions. Therefore, there is an urgent need for an adjustment device for repairing the tunnel boring machine cutting head to solve the above-mentioned shortcomings. Utility Model Content
