Second sliding clamping strip has installation gap between the first sliding clamping strip and the second sliding clamping strip, and described
Clamping baffle is provided on first sliding clamping strip and the second sliding clamping strip.
Further, the both ends of the bearing plate are provided with mutually matched bolt hole and fixing bolt, the sliding clamping
The both ends of item are provided with clamping strip slippage slot corresponding with the bolt hole, and the fixing bolt slides through the clamping strip
Slot is simultaneously matched with the bolt hole.
Further, arc port, the folder are formed between sliding clamping strip and the convex structure of the bearing plate
The size for holding baffle is adapted with the size of the arc port.
Further, the clamping baffle plate setting is in the inside of the sliding clamping strip.
Further, the pressure head is the cylindrical-shaped structure that lower end surface has circular arc.
Further, the length of the sliding clamping strip is consistent with the length of the bearing plate.
The utility model has the following beneficial effects: a kind of folder of Brazilian diametral compression test test specimen provided by the utility model
Device is held, simple installation operates convenient, high reliablity, by two slip clamping strips on bearing plate, realizes to different thickness
Positioning, the installation for spending disk rock sample effectively prevent the test specimen in installation and loading procedure inclined by clamping the constraint of baffle
Turn, aid abuts, it is ensured that the accuracy of test result.

12- second slides clamping strip, and 3- clamps baffle, 4- bolt hole, 5- fixing bolt, 6- clamping strip slippage slot, the examination of 20- rock disk
Test part.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figures 1 to 4, a kind of clamping device of Brazilian diametral compression test test specimen, including bearing plate 1, pressure head 2 and set
Set the sliding clamping strip in 1 upper end of bearing plate;The upper surface of bearing plate 1 and the lower end surface of pressure head 2 are in arc-shaped.Pressure head 2
It is directly connected to press machine, bearing plate 1 is placed on press machine testing stand, and the convex structure in bearing plate 1 is for placing rock
Stone disc test part 20.Before being tested, make the top phase of pressure head 2 with the rock disc test part being placed on bearing plate 1
Contact, then gradually application pressure can carry out Brazilian diametral compression test.
Sliding clamping strip includes the first sliding clamping strip 11 and that sliding respectively is connected on 1 upper surface of bearing plate
Two sliding clamping strips 12 have installation gap, and the first sliding between first sliding clamping strip 11 and the second sliding clamping strip 12
Clamping baffle 3 is provided on clamping strip 11 and the second sliding clamping strip 12.First sliding clamping strip 11 and the second sliding clamping
The structure of item 12 is consistent, and the length of each sliding clamping strip is consistent with the length of the bearing plate 1.Rock disc test part is placed
In in installation gap, rock disc test part is fastened by the first sliding clamping strip 11 and the second sliding clamping strip 12,
Guarantee that the installation of rock disc test part is reliably fixed, and passes through the cunning of the first sliding clamping strip 11 and the second sliding clamping strip 12
Transposition section and then the size for adjusting installation gap improve folder to realize the positioning to different-thickness disk rock sample, installation
Hold the service performance of device.Clamping baffle 3 and sliding clamping strip are connected as one formula structure, and clamping baffle 3 is located at sliding clamping
The inside of item, inside are sliding clamping strip close to the side of rock disc test part, the side far from rock disc test part
For outside.By the clamping baffle 3 of the first sliding clamping strip 11 and the clamping baffle 3 of the second sliding clamping strip 12 to rock circle
The restrict of disk testpieces installation site effectively prevent the rock disc test part in installation and loading procedure to deflect feelings
Condition.
It is adjusted for the ease of sliding the sliding of clamping strip, in the utility model, the both ends of bearing plate 1 are provided with mutual cooperation
Bolt hole 4 and fixing bolt 5, the both ends for sliding clamping strip are provided with clamping strip slippage slot 6 corresponding with bolt hole 4, Gu
Bolt 5 is determined through clamping strip slippage slot 6 and is matched with bolt hole 4.It is four that bolt hole 4 is mating with fixing bolt 5, for solid
Surely clamping strip is slid, when needing that rock disc test part is fixed, rotary fixing screw bolt 5, so that fixing bolt 5 and spiral shell
Connection between keyhole 4 loosens, then carries out sliding clamping strip to slide onto appropriate location along clamping strip slippage slot 6, then again will
Fixing bolt 5 is tightened, fixed sliding clamping strip.Its is easy to operate simple, and it is convenient to adjust.
In order to improve the function and effect of clamping baffle 3, in the utility model, the arc-shaped of clamping strip and bearing plate 1 is slid
Arc port is formed between opening, the size of clamping baffle 3 is adapted with the size of the arc port, so that clamping baffle 3
It is in the state of opposing seal between arc port, not only can guarantee the aid effect to rock disc test part, but also is avoided that outer
Boundary's impurity enters the influence of clamping device error caused by test.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
