Description
Technical field
The utility model relates to a kind of test apparatus, especially a kind of tetrad direct shear apparatus of the shear strength for detecting soil property, belongs to test apparatus technical field.
Background technology
Boxshear apparatus is widely used in the soil analysis built as a kind of geotechnological detecting instrument, existing boxshear apparatus is generally electronic tetrad direct shear apparatus, it comprises worktable, motor on the table and four groups of test suites, often organize test suite and comprise worm gear case, shear box, proving ring and top-pressure part, motor and a worm gear case are in transmission connection, the worm gear case of four groups of test suites is in transmission connection successively, and each worm gear case is provided with telescopic apical axis relative to shear box side.During boxshear apparatus work, the material of required detection is put into shear box respectively, rotated by the axle in each worm gear case of driven by motor, the apical axis of each worm gear case is stretched out respectively to the shear box direction of correspondence, and constantly promote shear box, shear box promotes proving ring again, because proving ring is fixing on the table, cause shear box to be out of shape, until detected material breaks, then measure the shear parameters of tested substance according to the reading of each proving ring.In the shear test of above-mentioned tetrad direct shear apparatus, often organize the worm gear case of test suite, shear box, proving ring stress point have higher status requirement, otherwise can test figure be affected.Due to the worm gear case often organizing test suite, shear box, the proving ring of current tetrad direct shear apparatus, after corresponding cushion block being installed at worktable, be fixed on cushion block, because the area of worktable is relatively large, relatively be difficult to ensure the level of card worktable, therefore often organize the more difficult control in stress point position of the worm gear case of test suite, shear box, proving ring, have impact on test figure accuracy.The often group test suite of simultaneously above-mentioned structure is arranged on worktable all needs in-site installation, have impact on work efficiency.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined be to provide a kind of ensure often to organize test suite worm gear case, shear box, proving ring the tetrad direct shear apparatus of stress point position, with warranty test data accuracy.Also can improve the production efficiency manufacturing tetrad direct shear apparatus simultaneously.
For solving the problem, the utility model have employed following technical scheme: a kind of tetrad direct shear apparatus, it comprises worktable, motor on the table and four groups of test suites, described test suite of often organizing comprises worm gear case, shear box, proving ring and top-pressure part, described motor and a worm gear case are in transmission connection, the worm gear case of described four groups of test suites is in transmission connection successively, described each worm gear case is provided with telescopic apical axis relative to shear box side, it also comprises the test suite substrate of four pieces of strips, described test suite substrate is provided with proving ring roof platform successively, proving ring erecting bed, shear box mounting groove, worm gear case, described proving ring is arranged between proving ring roof platform and proving ring erecting bed, described shear box is arranged in shear box mounting groove.
Described proving ring erecting bed is provided with longitudinal proving ring mounting hole.
Said structure, tetrad direct shear apparatus of the present utility model, owing to being provided with four test suite substrates, and test suite substrate is provided with successively proving ring roof platform, proving ring erecting bed, shear box mounting groove, worm gear case, proving ring is arranged between proving ring roof platform and proving ring erecting bed, and shear box is arranged in shear box mounting groove.Can ensure so often to organize the worm gear case of test suite, shear box, proving ring stress point in a straight line, warranty test data accuracy.
Simultaneously, owing to often organizing the proving ring of test suite, the elements such as worm gear case are arranged on test suite substrate, and the element installation on test suite substrate can adopt stream line operation, the element treating often to organize test suite is arranged on each test suite substrate, as long as by fixing on the table for each test suite substrate that element installation is housed, then motor and a worm gear case are in transmission connection, the worm gear case of four groups of test suites is in transmission connection successively, just complete the installation of tetrad direct shear apparatus, therefore, tetrad direct shear apparatus of the present utility model, also can improve the production efficiency manufacturing tetrad direct shear apparatus.
