Description
Technical field
The invention belongs to shale experimental technique field, more particularly to a kind of rotary shale rock sample coring base and its operation
Method.
Background technology
When the experiment related to shale rock sample is done, some experiments need that column is taken from shale rock sample with drill hole sampling machine
Core, in coring, using hollow boring bit machine can coring automatically, if shale rock sample fixation is just taken
Core, it is likely that move on rock sample, it is impossible to enough realize stable coring；Meanwhile, when needing to carry out multiple coring to same rock sample, need
To move by hand and rotate rock sample or mobile drill hole sampling machine, artificial repeatedly mobile rock sample may result in rock sample breakage or destruction rock
The crack structtire of sample, and inefficiency；Using hollow boring bit machine in coring, the device of shale rock sample is not fixed, caused
Inconvenience during operation, rock sample is easily moved, the problems such as the low error of coring success rate is big.
The content of the invention
The technical problem to be solved in the present invention：A kind of rotary shale rock sample coring base and its method of operating are provided, with
The needs craft movement for solving to there is shale rock sample coring in prior art rotates rock sample or mobile drill hole sampling machine, artificial many
Secondary mobile rock sample may result in the crack structtire of rock sample breakage or destruction rock sample, and inefficiency；Using hollow boring bit machine
In coring, the device of shale rock sample is not fixed, cause inconvenience when operating, rock sample easily to move, the low mistake of coring success rate
The problems such as difference is big.
Technical solution of the present invention：
A kind of rotary shale rock sample coring base, it includes base, rolling bearing is provided with base, solid on rolling bearing
Surely there is base plate, backing plate is fixed with base plate.
Slip grip block is respectively arranged on the left side and the right side in base plate upper padding plate.
Slip grip block is connected with transmission device, and transmission device is connected with support base.Support base is fixed on base plate.
Transmission device is screw rod transmission structure, and the end screw mandrel of screw rod transmission structure is provided with handle.
Backing plate is circle, and the diameter of backing plate is identical with the diameter of shale rock sample.
Slip grip block is arcuate structure, and the height of slip grip block is the 70%-95% of shale rock sample height.
The method of operating of described rotary shale rock sample coring base, it includes：
Step 1, circular shale rock sample is placed on backing plate；
Step 2, operating and driving device movement slip grip block, shale rock sample and backing plate are clamped；
Step 3, rotary motion bearing, by shale rock sample coring position alignment coring device, carry out coring；
Step 4, repeat step 3, continuation carries out coring to shale rock sample.
Beneficial effects of the present invention：
Present configuration is simple, easy to operate, shale rock sample is once clamped, you can carry out multiple coring to shale rock sample；No
Mobile shale rock sample is needed repeatedly, the needs existed to shale rock sample coring in prior art mobile rotation rock sample by hand is solved
Or mobile drill hole sampling machine, artificial repeatedly mobile rock sample may result in the crack structtire of rock sample breakage or destruction rock sample, and imitate
Rate is low；Using hollow boring bit machine in coring, the device of shale rock sample is not fixed, cause inconvenience when operating, rock sample
It is easily mobile, the problems such as the low error of coring success rate is big.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is schematic top plan view of the present invention.
Specific embodiment
A kind of rotary shale rock sample coring base, it includes base, rolling bearing 2, rotary shaft is provided with base 1
Hold and be fixed with 2 base plate 8, backing plate 7 is fixed with base plate.Shale rock sample is placed on backing plate 7 and is taken by sampler
Core, after coring terminates, rotary motion bearing 2, you can continuation carries out coring next time to shale rock sample, it is not necessary to artificial move page
Rock rock sample, improves operating efficiency, it is to avoid artificial directly mobile shale rock sample causes the crackle of shale rock sample breakage or destruction rock sample
The problems such as structure.
Slip grip block 3 is respectively provided with the left and right sides of the upper padding plate 7 of base plate 8, mobile slip clamp is held plate 3 and clamped before coring
Shale rock sample, it is to avoid shale rock sample is moved in location of the coring procedure, improves coring success rate, reduces coring error.
Further, slip grip block 3 is flexibly connected with transmission device 5, transmission device 5 is connected with support base 4.Support base
4 are fixed on base plate 8.Transmission device 5 is screw rod transmission structure, and by operating screw rod transmission structure slip grip block 3 is realized
Back and forth movement, reduces the labour intensity of artificial directly mobile slip grip block 3.The fixing nut of screw rod transmission structure is fixed on props up
In the supported hole of support seat 4.
Further, in order that operation screw rod transmission structure is easier, on the end screw mandrel of screw rod transmission structure hand is provided with
Handle 6, is capable of achieving screw rod transmission structure and moves forward and backward by operation handle, time saving and energy saving and be difficult hand of making dirty.
Backing plate 7 is circle, and the diameter of backing plate 7 is identical with the diameter of shale rock sample；Can be further assured that the energy of slip grip block 3
Shale rock sample and backing plate 7 are enough simultaneously clamped on, makes shale rock sample not produce relative slip with backing plate 7.
