Description
Technical Field
The utility model relates to a shield constructs quick-witted manufacturing technology field, in particular to shield constructs variable diameter adjustment structure of quick-witted weak soil blade disc cutter.
Background
In order to further meet the traveling demands of citizens, more and more cities in the country build rail transit facilities, and subway construction becomes a flag of rapid development of the urban rail transit industry. Therefore, the demand of the subway tunnel shield machine is increasingly large, and the manufacturing quantity of the new shield machine is increased year by year at present. Under the strong support of the state, the shield machine industry makes great development and progress, and breaks through the long-term monopoly situation abroad. Although the overall level still has a lot of gaps, the international leading level is reached in some aspect.
The cutter head is a key structure of the whole shield machine. The structural form of the concrete wall is panel type and spoke type, and the concrete application is determined according to factors such as construction conditions, soil conditions and the like. The spoke type cutter head only has a plurality of spokes, the cut soil body directly enters the soil bin without pressure loss, and meanwhile, the stirring blades are arranged behind the spokes, so that the soil and sand flow smoothly, and the soil pressure balance is easy to control. Therefore, the adaptability of the spoke type cutter head to single soft soil strata such as sand, soil and the like is stronger than that of a panel type cutter head; however, as the spoke type cutterhead cannot be provided with the hob, a panel type cutterhead is adopted when the weathered rock and the stratum with uneven hardness or the hard rock stratum are tunneled.
The entire cutterhead cutter is configured as a conventional soft soil cutter, which may present several more complicated problems because the cutterhead spokes are not length-changeable. If the shield machine is transported to a construction site, the spokes are found to be inconsistent with the actual construction diameter, or if the spokes need to be changed in the using process, the lengths of the spokes need to be changed. However, the conventional method for solving the problems wastes time and labor, and the cutter head needs to be transported back to a manufacturer for remanufacturing, so that not only is the time wasted, but also the use cost of the shield machine is greatly increased, and the transportation of large-scale equipment is a very complicated and expensive process.
