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:
The present invention relates to a kind of cutter research experiment equipment, the experimental facilities cutter rock breaking mechanism and the abrasion wear test machine of particularly a kind of shield structure disk cutter research aspect.
Background technology:
At present, cutter rock breaking mechanism and abrasion wear test machine are the special experimental facilitiess of a broken rock process of simulation hard rock shield structure hobboing cutter.By the simulation of hobboing cutter cutting rock process being studied the wearing quality of the rock breaking mechanism and the cutter material of cutter.As far back as the seventies experimental facilities of similar research cutter is just arranged abroad, but significant limitation is arranged on research contents, some be suggested in the recent period to the broken influential key factor of rock as researchs that can't experimentize such as " phasing degree ", " interior drift angles "; The laboratory facilities of just studying in the past that the broken influential factor of rock was waited as " cutter spacing " " being used to in-degree " and the reliability of image data also need raising.Therefore developing a kind of cutter rock breaking mechanism and abrasion wear test machine is the new problem of being badly in need of solution both at home and abroad.
Summary of the invention:
The purpose of this invention is to provide a kind of function that increases cutter rock breaking mechanism and abrasion wear test machine, study breaking factors such as the bigger cutter spacing of rock and tool wear influence, phasing degree, interior drift angle, cutter rock breaking mechanism and abrasion wear test machine solve two hobboing cutters simultaneously cutting rock the time, the adjusting problem of the cutter spacing between the hobboing cutter, phasing degree, interior drift angle, thus carry out cutter spacing, phasing degree, interior drift angle cutter rock breaking mechanism and abrasion wear test machine to the research of influence of cutter rock breaking efficiency and tool wear aspect.
The object of the present invention is achieved like this: cutter rock breaking mechanism and abrasion wear test machine, comprise hydraulic cylinder, structural framing, bearing plate, knife rest, disk cutter, rotary table, when cutter rock breaking mechanism and abrasion wear test machine work, disk cutter is connected with knife rest by bolt, knife rest is fixed on the bearing plate closing by bolt again, hydraulic cylinder applies certain load, disk cutter is compressed be placed on the rock sample on the worktable and produce certain pile penetration, make worktable be rotated motion by power system afterwards, passive carries out cutting experiment to rock; Cutter rock breaking mechanism and abrasion wear test machine carry out the wearing quality experiment that cutter is made in the hilted broadsword cutting, carrying out double-pole cuts simultaneously and does the experiment of cutter spacing and phasing degree, fluted on the bearing plate, the adjusting at cutter spacing and phasing degree realizes the variation of closing the position on bearing plate by knife rest, realize the adjusting of drift angle in the cutter by the knife rest of changing different angles, the location of rock and rotation rely on rotary table to realize; Its principle of work is, under the effect of the huge thrust of hydraulic cylinder, hobboing cutter is pressed into rock, rotary table drives rock and rotates, cutter head of shield machine drives hobboing cutter and revolves round the sun around cutter spindle, simultaneously each hobboing cutter also around separately cutter shaft rotation, makes hobboing cutter roll extrusion continuously on rock face, and it is broken to the extruding of rock and shearing rock to be taken place by hobboing cutter.
Main points of the present invention are its structure and principle.Its principle of work is, under the effect of the huge thrust of hydraulic cylinder, hobboing cutter is pressed into rock, rotary table drives rock and rotates (be equivalent to cutter head of shield machine drive hobboing cutter revolve round the sun around cutter spindle), simultaneously each hobboing cutter is also around separately cutter shaft rotation, make hobboing cutter continuously roll extrusion on rock face, it is broken to the extruding of rock and shearing rock to be taken place by hobboing cutter.
Cutter rock breaking mechanism and abrasion wear test machine are compared with prior art, has novel science, increase the function of cutter rock breaking mechanism and abrasion wear test machine, broken rock of research and bigger cutter spacing, phasing degree, the interior drift angle of tool wear influence, solve two hobboing cutters cutting rock simultaneously, advantages such as the cutter spacing between the adjusting hobboing cutter, phasing degree, interior drift angle will be widely used in the cutter experimental technique field.
