Description
Technical field
The invention belongs to Rock Mechanics Test technical fields, are specifically related to a kind of portable Rock Mechanics Test test specimen mill
Model machine.
Background technique
Rock Mechanics Test is the basic experiment of ground mine and its related discipline, in the mine class engineering safety production of guidance ground
It is to obtain the mechanical properties such as coal petrography compression strength, tensile strength, shear strength in mining industry and correlation engineering with critical role
The important channel of parameter, can arrange for tunnel (side slope) construction, mine working and the offers such as supporting, exploitation of mineral resources mode are theoretical
Property reference.Rock Mechanics Test is that reduction dimensional effect influences, and is often processed sample according to certain code requirement, sample
Also difference need to be required for sample dimensions by drill core, cutting, the big process of grind away three, different mechanical properties test experiments by producing,
Height of specimen is followed successively by resistance to compression test specimen, shear test block, splitting (tension) test specimen from large to small.Now test piece cutting machine uses double-pole
Cutting form is usually arranged compared with cut crushing resistance between blade to reduce influence of the blade to sample dimensions and end flatness
The spacing of the long 1mm~2mm of energy testing standard test specimen, crush test test piece end need to directly connect with pressing disc on pressure testing machine
Touching.To guarantee test specimen uniform force, experiment is high for test piece end flatness requirement, and polishing end need to just come by sample grinding machine
It realizes.Draw, cut experiment piece lengths it is short and only resistance to compression length 1/4~1/2, generally cut using hilted broadsword, cutting examination
Part length in reserve 1mm~2mm long compared with standard specimen is cut in blade cutting process since the part retained needed for cutting is hanging
Power and machine vibration amplitude are big, easily broken at the end of test specimen cutting is fast it is disconnected forms boss, therefore draw, cut test specimen also need to be by sample grinding machine
Test piece end Accuracy control sample dimensions simultaneously are polished, sample grinding machine can more preferably control sample dimensions and force-bearing situation, to protect
Demonstrate,prove Rock Mechanics Test effect, experimental data accuracy and Engineering Guidance reliability.Sample grinding machine overall dimensions now are big, emery wheel
On frosted be concentrated mainly on emery wheel edge side, if misoperation easily causes frosted to fall off and damages emery wheel, emery wheel price is past
Toward higher so that the increase of later period use cost presses when fixing wait grind test specimen, cuts piece lengths generally on the left side 50mm~100mm
In right range, can preferably it fix, grind away is also relatively easy to；Then in 25mm or so, test specimen is shorter to be not easy admittedly tensile test piece length
Fixed, the spacing of emery wheel and fixed specimen appliance is small to cause grind away process restraining factors to increase, and the grind away time is long.For now grind away
Some defects existing for machine try hard to research and develop a kind of Rock Mechanics Test test specimen mill that easy to operate, small-sized, safe, practical property is high
