Abstract

The invention relates to a device for testing wear resistance of a disc cutter of a TBM (tunnel boring machine). The device comprises a base (1), a reaction frame (2), a vertical hydraulic cylinder (3), vertical guide rods (4), a vertical stress cushion block (5), a bearing (6), a cutter-like body (7), a cutter ring fixture (8), a cutter ring sample (9), a model case (10), a rock sample (11), a model case fixing block (12), transverse slides (13), a transverse hydraulic cylinder (14) and a test system, wherein the transverse hydraulic cylinder (14) drives the rock sample (11) to reciprocate in a horizontal plane, the vertical hydraulic cylinder (3) drives the cutter ring sample (9) to move up and down in a vertical plant, the cutter ring sample (9) reciprocates along with the rock sample (11) to realize reciprocating rolling, and the wear resistance of the cutter ring sample is tested through the test system. Compared with the prior art, the device can test the wear resistance of different cutter rings and can test effects caused by different factors on wear to the cutter rings.

Description

Technical field [0001] The invention relates to a device for testing the interaction between a disk hob of a TBM hard rock tunneling machine and a rock, in particular to a test device for the wear resistance of the disk hob cutter ring of a tunneling machine. Background technique [0002] In recent years, my country's underground space engineering construction has been carried out on a large scale, and long and large tunnels have been built. The level of construction mechanization has gradually improved. TBM tunneling technology has been widely used due to its advantages in construction speed, safety, quality, and environmental protection, and its localization trend It is also becoming more and more obvious. As the main rock breaking tool of TBM, the disc hob has a service life that directly affects the construction efficiency and cost of TBM. When the hob breaks the rock, the hob cutter ring itself wears, which is divided into normal wear and abnormal wear. According to a large ...
