Abstract

The present invention provides a cutter rock-breaking mechanism which is applied in the technical field of the cutter experiment and an abrasion resistant tester thereof. The abrasion resistant tester comprises a hydraulic cylinder, a structural frame, a bearing plate, a cutter support, a disc-shaped hob and a rotation worktable. When the cutter rock-breaking mechanism and the abrasion resistant tester work, the disc-shaped hob is connected with the cutter support through a bolt. The cutter support is jointed and fixed on the bearing plate through the bolts. The hydraulic cylinder exerts a certain load to impact the disc-shaped hob to the rock sample on the worktable and generate a certain penetration. Afterwards the worktable is rotated through a power system to execute cutting test to the rock passively. The cutter rock-breaking mechanism and the abrasion resistant tester execute cutting with a single cutter to do the abrasion resistance test of the cutter. The bearing plate is provided with a groove. The regulation to the cutter space and the phase angle is realized through the variation of the jointing position of the cutter support on the bearing plate. The regulation to the inner deflection angle of the cutter is realized by changing the cutter supports with different angles. The positioning and rotation of the rock are realized through the rotating worktable. The designing of the device is novel and scientific. The knife angle, phase angle and inner deflection angle which affect larger to the rock breaking and abrasion of cutter are researched. The device settles the problem that two hob cutters simultaneously cut the rock.

Description

Technical field:

[0001] The invention relates to a cutting tool research experimental equipment, in particular to a cutting tool rock-breaking mechanism and wear-resistant testing machine for the experimental equipment in the field of shield machine disc hob research. Background technique:

[0002] At present, the tool rock breaking mechanism and wear resistance testing machine is a special experimental equipment for simulating the rock breaking process of the hard rock shield hob. By simulating the rock-cutting process of the hob, the rock-breaking mechanism of the cutter and the wear resistance of the cutter material are studied. As early as the 1970s, there were similar experimental equipment for researching knives in foreign countries, but there were great limitations in the research content. Some important factors that have recently been proposed that have an impact on rock breaking, such as "phase angle" and "inner deflection angle" Experimental research cannot be car...
