There is larger slip.This apparatus structure rationally, be simple and convenient to operate, the accuracy of test data can be improved, considerably increase examination
The effectiveness of experiment device.
For reaching above-mentioned purpose, this utility model employs the following technical solutions:
A kind of swash plate instrument, including upper flat plate, lower flat board, plate end hinge, rigid bearing plate, hydraulic jack, displacement transducer,
Pass through plate end hinge-connection, under lower flat board, four table legs of welding are as the support of lower flat board between described upper flat plate and lower flat board；Institute
State upper flat plate upper surface and be provided with Sanding Area, Sanding Area is placed with test granular materialss, test granular materialss are put
Put rigid bearing plate；The central spot of described lower flat board is provided with macroscopic void, and described hydraulic jack is placed on footstool, its support
End is connected through macroscopic void with upper flat plate, described lower flat board is additionally provided with small holes, institute's displacement sensors are arranged on small holes
On.
Described Sanding Area forms through rough polish.
Groove is reserved in described upper flat plate lower surface middle part, matches so that supporting with the support end of hydraulic jack
End will not change direct of travel when sliding in a groove.
Described rigid bearing plate lower surface is polished into hair side, and the both sides of rigid bearing plate are provided with hook, for hanging counterweight.
This utility model compared with prior art, has and will be apparent below salience feature and remarkable advantage:
The upper and lower flat board of this utility model all adopts lightgage steel joist frame structure, in surface soldered 1cm steel plate, makes upper flat plate
With lower flat board lighter in weight itself；Upper flat plate upper face is polished into hair side, so that when placing granular materialss, granular materialss will not
There is larger sliding；Rigid bearing plate lower surface is polished into hair side, so that when test material is placed thereunder, uses in outer masterpiece
Under, there is sliding with rigid bearing plate lower surface in test material；Using hydraulic jack have that lifting capacity is big, rapid operation,
The advantages of rise steady, safe and reliable, its rate of climb is slower, meets the rate request of ramp test.From oil jack
The lifting on top is 5～30t, and maximum is up to 500t；The height of raising is 100mm-200mm.
