【摘要】：为了研究岩石特性对TBM滚刀刀圈磨损的影响,本文基于TBM滚刀性能测试试验台,利用与实际TBM滚刀刀圈性能相同的滚刀刀圈试样,开展了滚刀刀圈试样与5种TBM工程典型岩石的对摩实验。结果表明:随着对摩岩石抗压强度的升高,刀圈试样的磨损量呈递增趋势,与红砂岩对摩时刀圈试样的磨损量最小,为0.2 g;与片麻岩对摩时刀圈试样的磨损量最大,为35.18 g;与红砂岩、锈石、花岗岩、汨罗麻岩四种岩石对摩时,刀圈试样的磨损去除机制均以微观切削去除为主,只是微观切削去除的程度不同;与片麻岩对摩时,刀圈试样所受载荷和振动较大,刀磨损机制转变为以微观切削和脆性断裂去除机制为主,导致刀圈试样磨损量剧增。本研究成果可为不同岩石特性下TBM滚刀刀圈性能选型提供借鉴和参考。
[Abstract]:In order to study the influence of rock characteristics on the wear of TBM hob ring, this paper uses the hob ring specimen which is the same as the actual TBM hob ring performance based on the TBM hob performance test rig. Friction experiments of hob ring specimen and five typical rocks of TBM engineering were carried out. The results show that with the increase of compressive strength of friction rock, the wear amount of cutter ring specimen is increasing, and the wear amount of cutter ring specimen is the smallest (0.2 g) with red sandstone, and the largest wear amount is with gneiss specimen. The wear removal mechanism of the sabre specimen is mainly micro-cutting removal, but the degree of micro-cutting removal is different from that of gneiss, the wear removal mechanism is 35.18 g with red sandstone, rusty stone, granite and Miluo granitic rock, and with gneiss, the wear removal mechanism is mainly micro-cutting removal, but the degree of micro-cutting removal is different from that of gneiss. The wear mechanism of the cutter was changed into the micro-cutting and brittle fracture removal mechanism, which resulted in the sharp increase of the wear amount of the cutter ring specimen. The results of this study can be used for reference and reference for the performance selection of TBM hobs under different rock characteristics.
