A kind of test method for combining fractured rock experimental rig using above-mentioned diamond saw blade-pick, including step is such as
Under:
One, rock fixation procedure:
The elongation of cabinet propelling cylinder promotes the fixed device of rock to move along box body guide rail to saw blade component support frame direction,
When the fixed device of rock is among cabinet baffle and saw blade component support frame, cabinet propelling cylinder stops working；
It is put into rock in cabinet, using allen wrench rotational fastener bar, moves anchorage bar toward box house direction,
Rock fixed plate is pushed to move to box house direction, two sides rock fixed plate clamps rock；
Two, rock saw blade cuts are deep-controlled:
By elongating or shortening for cabinet propelling cylinder, the position of the fixed device of rock is adjusted, makes rock in saw blades groups
Underface；
Saw blade propelling cylinder pushes saw blades groups to move downward, while starter motor, drives saw blades groups rotation；It is promoted with saw blade
The promotion of oil cylinder, saw blades groups close to and start rock cutting, pass through the elongation of control saw blade propelling cylinder, control saw blade cuts
The depth of rock；Saw blade propelling cylinder drives saw blades groups to lift, and motor stops operating；
Three, rock saw blade cuts saw kerf length controls:
During saw blades groups rock cutting, cabinet propelling cylinder can drive the fixed device of rock to move on box body guide rail,
After rock slot length needed for obtaining, cabinet propelling cylinder stopping movement, saw blade propelling cylinder drives saw blades groups to lift, motor
It stops operating；
Four, rock saw blade cuts joint-cutting spacing controls:
The joint-cutting spacing of saw blades groups rock cutting depends on the length of spacer sleeve；Pulling off sleeves group, middle hubcap, replacement
The spacing in saw blades groups between each saw blade can be changed in the spacer sleeve of appropriate length, and cutting obtains required joint-cutting spacing, passes through
Adjusting sleeve obtains specified Rock Cutting thickness with the spacing distance of group and saw blades groups；
Or,
Relative position between saw blades groups and rock can be changed by the mobile saw blade modular support frame of saw blade component propelling cylinder
Become: after saw blades groups sawing rock forms the joint-cutting of a fixed spacing, saw blade propelling cylinder drives saw blades groups to rise, and passes through saw blade component
Flexible, the relative position of adjustment saw blade component support frame and saw blades groups and rock of propelling cylinder, saw blade propelling cylinder drive gold
The decline of hard rock saw blades groups, is cut again, and joint-cutting spacing can be changed；After the completion of cutting, saw blade propelling cylinder drives saw blade
Group rises again, closes motor.
Five, the acquisition of clipping force:
The rock completed by saw blades groups cutting, is moved in cabinet baffle by the contraction of cabinet propelling cylinder, is cut
Tooth cutting component moves under the drive of cutting bit assembly propelling cylinder along cutting package traces direction, and pick impact grinding has and cuts
The rock of seam, rock make pressure bar compression pressure sensor to the reaction force of pick, and the deformation of pressure sensor is with electric current
Signal is exported by signal acquisition interface, completes test acquisition.
The beneficial effects of the present invention are:
1. the present invention devises a kind of diamond saw blade-pick joint fractured rock experimental rig, which can
It completes to study the crushing test of rock.
2. experimental rig saw blade component of the invention is made of multiple saw blades, a plurality of saw kerf can be carried out to lithosome simultaneously
Sawing.
3. experimental rig of the invention can by the feeding distance of sawing propelling cylinder, complementary saw blade component to rock into
Row sawing forms different sawing joint-cutting depth.
4. experimental rig of the invention can by the feeding distance of the fixed oil cylinder of rock, complementary saw blade component to rock into
Row sawing forms different sawing slot lengths.
5. experimental rig of the invention can carry out sawing to rock by the effect of slotted socket, complementary saw blade component,
By changing the width of spacer sleeve, different sawing joint-cutting spacing can be formed, to form the rock plate body of different-thickness.
6. experimental rig of the invention can also drive saw blade component by the effect of saw blade component support frame propelling cylinder
Support frame is moved, and complementary saw blade component carries out sawing to rock, and then forms different sawing joint-cutting spacing, to be formed not
The rock plate body of stack pile.
7. the saw blade component support frame of experimental rig of the invention is positioned using support frame positioning device, it is ensured that saw
Piece modular support frame is steady on guide rail, smooth mobile, phenomena such as will not toppling over.
8. experimental rig of the invention has rock clamping assembly, which can complete to consolidate different size rocks
It is fixed, and rock can be fixed by acting on different height for backing plate.
9. experimental rig of the invention can assist pick cutting component to complete not by the fixation to different height rock
Cutting with cutting depth plate rock mass is broken.
10. the pick cutting component of experimental rig of the invention has bearing-type bending resistance square structure, the advantage of the structure
It is, 1. can offsets the moment of flexure that pick cutting power generates pick cutting modular construction, pick 2. can be made to promote oil in pick
It moves linearly in cylinder progradation more steady.
It, can be in bearing-type bending resistance square 11. the pick cutting component of experimental rig of the invention has pressure sensor
The normal direction clipping force during pick fractured rock is accurately measured under the auxiliary of structure.
12. the structure according to the present invention with saw blade collocation fractured rock is pick, the cutterhead for pick installation
Size be easy to control.After saw blade cuts rock, the intensity of rock can be significantly reduced, cutterhead volume, lower-powered situation
Under can also complete to be crushed plate rock mass.
