Embodiment Construction
[0041] The detailed content of the present invention and its specific implementation will be further described below in conjunction with the accompanying drawings.
[0042] see Figure 1 to Figure 9 As shown, the tension-shear preload in-situ indentation test device of the present invention consists of four parts: a mechanical transmission module, an arbitrary-angle tension-shear composite loading module, a cantilever indentation module and a measurement module.
[0043] The mechanical transmission module includes a main frame 11, a primary worm gear 23 and a primary worm 22 provide a primary deceleration, a connecting rod 24, a secondary worm gear 26, and a secondary worm 28 provide a secondary deceleration, a secondary worm support frame a27, and a secondary worm The first-stage worm support frame b30, because the second-stage worm gear protrudes too long, the auxiliary support frame 25, the motor support frame 21 to increase its rigidity, the reducer 20 placed to obtain the...
