Background technology
Geotechnical engineering occupies very important status in today's society, and tunnel, mine hole and tunnel etc. all be unable to do without ground
The research of engineering, tensile strength are an important parameters of rock soil test piece mechanical property.Since direct tensile test is in operation
Compare difficult completion, the Indirect Tensile Tests method of generally use Brazil diametral compression test is strong come the tension for testing rock soil test piece in the world
Degree, but traditional Brazilian diametral compression test grip device is inaccurate, insufficient in the presence of being fixed to rock soil test piece, in loading procedure easily
It is eccentric to there is rock soil test piece, i.e., it cannot be guaranteed that tensile stress is by the way that rock soil test piece central shaft causes test error the shortcomings of, therefore
Design a kind of improved During Geotechnical Tests with Brazilian diametral compression test grip device come during guarantee test safety and experiment tie
The accuracy of fruit, it appears particularly necessary.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of Brazilian diametral compression tests of improved During Geotechnical Tests to press from both sides
Has device, it is intended to drive clamping plate movement to realize the accurate fixation to rock soil test piece by ball-screw, while testing machine is applied
Pressure become linear load and make to generate inside rock soil test piece to keep rock soil test piece broken perpendicular to the tensile stress of upper and lower load action direction
It is bad to measure the tensile strength of rock soil test piece in turn, and then overcome traditional During Geotechnical Tests and fixed with Brazilian diametral compression test grip device
Inaccurately, insufficient, easily occur rock soil test piece bias in loading procedure, i.e., it cannot be guaranteed that tensile stress passes through rock soil test piece center
Axis and the shortcomings of cause test error, ensure that the accuracy of the safety and test result during experiment.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of improved During Geotechnical Tests Brazil's splitting
Test fixture device, including base device and clamping device.
The base device includes pedestal, filler strip, pillar, bearing plate, nut, the filler strip totally two, described two pads
Item is horizontally fixed on respectively on the center line of pedestal upper surface and bearing plate lower face, totally four, the pillar, four branch
Column is fixed and is symmetric in pedestal, and the bearing plate can be moved up and down along pillar, totally four, described four, the nut
Nut uses screw-thread fit four pillar upper ends.
It is that the pillar provides positioning and guiding role for bearing plate movement to use the advantageous effect of above-mentioned technical proposal.
The clamping device includes scale strip, bearing, guide rail, handle, screw rod, clamping plate and bearing, the scale strip totally two
A, described two scale strips are symmetrically fixed on the base using pedestal upper surface center line as zero graduation, the bearing totally two, institute
Two bearings to be stated to fix and be symmetric in pedestal, totally two, the guide rail, described two guide rails are symmetrically fixed on the base,
Totally two, the handle, the screw rod totally two, totally two, the clamping plate, totally two, the bearing, the handle, bearing and spiral shell
Bar screw-thread fit forms ball-screw, and the bearing is fixed on clamping plate and is matched with screw rod.
Advantageous effect using above-mentioned technical proposal is that the screw rod and bearing form ball-screw, rolling using screw-thread fit
The rotary motion of ballscrew can be converted into linear motion so that screw rod is axially moveable, rotary motion of the bearing screw rod
It is converted into the linear motion of clamping plate, so that clamping plate is moved forward and backward fixed rock soil test piece along guide rail, the scale strip is with pedestal upper surface
Center line is that can adjust clamping device middle clamp plate according to the diameter of rock soil test piece for the symmetrical advantageous effect of zero graduation
Displacement distance come accurately fix rock soil test piece so that ensure rock soil test piece central shaft and filler strip it is corresponding, avoid loading
The test error caused by rock soil test piece bias in journey.

Fig. 1 is the utility model complete machine device schematic diagram；
Fig. 2 is the utility model base device schematic diagram；
Fig. 3 is the utility model clamping device schematic diagram；
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is only used for explaining this practicality
It is novel, it is not intended to limit the utility model.
In Fig. 1, the Brazilian diametral compression test grip device of the improved During Geotechnical Tests, including base device 1 and clamping
Device 2.
In fig. 2, the base device 1 includes pedestal 3, filler strip 4, pillar 6, bearing plate 7, nut 8, and the filler strip 4 is total
Two, described two filler strips 4 are horizontally fixed on respectively on the center line of 7 lower face of 3 upper surface of pedestal and bearing plate, the pillar
6 totally four, four pillars 6 are fixed and are symmetric in pedestal 3, and the bearing plate 7 can be moved up and down along pillar 6, institute
Totally four, nut 8 is stated, four nuts 8 use screw-thread fit four 6 upper ends of pillar.
In Fig. 2, Fig. 3, the clamping device 2 includes scale strip 5, bearing 9, guide rail 10, handle 11, screw rod 12, clamping plate
