Existing upper lower platen adds steel bar formula Brazil splitting clamping device test specimen is born not to heart load, and steel bar is easily embedded in test specimen,
It is unable to reach experiment purpose；Using circular arc type clamping device up and down, complex steps, security, accuracy are low.Nowadays it is real to seepage flow
The research tested is goed deep into, and existing device is merely able to form vertical to heart shake gap, realizes that many inclination angle cracks difficulty is big, therefore, exploitation
Go out a kind of splitting device easy to operate, high-precision and that many inclination angle cracks can be formed particularly significant.
The content of the invention
The purpose of this utility model is that solution test specimen bears the problem of difficult to heart concentrated force, crack angle is single,
To realize research of the seepage flow to different angle insertion fissure rock.
In order to realize above-mentioned experiment purpose, the technical scheme that the utility model is solved is that described many inclination angles Brazil cleaves
Test splitting device.Described device refers to including upper bearing plate, lower bearing plate, flexible fastening support, blade type pressure head, rotating disk and triangle
Pin, the upper and lower bearing plate left and right sides is respectively provided with triangle projection, triangle groove, and raised adaptable with groove, prevents in experiment
During upper bearing plate there is translation；The upper bearing plate lower surface carries blade type pressure head groove, can mount and dismount different swords
Type pressure head adapts to the test specimen of varying strength, and blade type pressure head with clamped test specimen linear contact lay and applies concentrated force to test specimen；The circle
Panel surface pointer groove is used for fixed triangle pointer；The disk upper surface has four screwed holes, will be flexibly positioned by bolt
Support is fixedly connected with rotating disk, to prevent test specimen from occurring lateral translation in cleaving process；The flexibly positioned rack elasticity compared with
It is good, to reduce influence of the rigid member constraint to experimental result；There are fixed blade type pressure head and scale in the lower bearing plate upper surface
Chi, fixed blade type pressure head is corresponding with the detachable blade type pressure head cooperation of upper bearing plate, and the heart is destroyed with realizing, triangle pointer and scale
Chi coordinates, and records the angle change of rotating disk.
It is as follows using detailed process of the present utility model during the Brazilian spilt test of different angle is carried out：
A. upper bearing plate and lower bearing plate are separated, suitable detachable blade type pressure head is chosen according to requirement of experiment, and will
Flexible fastening support is fixedly attached on disk with bolt, rotates disk, up to triangle indicators turn to specified angle.
B. the test specimen for needing to cleave is placed on flexible fastening support, then the triangle upper bearing plate along lower bearing plate
Groove is placed into above test specimen, makes the detachable blade type pressure head linear contact lay surface of test piece of bearing plate lower surface, whole device
Brazilian multi-angle spilt test can be carried out by being put in Slow loading under forcing press.
The utility model has the advantages that, it is simple in construction, the splitting of different angle test specimens, easy to operate and precision can be realized
Higher, substantially increasing the efficiency and precision of experiment, there is provided certain scientific research value.
