Description
Technical field
The utility model relates to a kind of full-automatic direct shear apparatus.
Background technology
Prior art is to utilize lever principle manually to add counterweight to apply vertical load, and manual control motor is sheared, and shear stress is surveyed by the circular rector of measuring one's own ability, manual read's note.The shortcoming of prior art: the one, manually move counterweight and apply vertical load, be subject to counterweight specification limits, load can not arrange arbitrarily; The 2nd, before shearing, whether the artificial distortion of judging that loading causes stablizes, so that starter motor starts to shear.In shear history, manually adjust lever levelness, eliminate the impact of sample deformation, to keep vertical load stable.Manual read remembers shearing data.Human factor is many, affects test findings; The 3rd, limited by sensitivity, the shear stress of surveying by the circular rector of measuring one's own ability, accuracy is lower; The 4th, process of the test is entirely by manual operation, and labour intensity is large, and test efficiency is low.
Utility model content
In order to address the above problem, the utility model provides a kind of vertical load that can keep in shear history stable and guarantee the full-automatic direct shear apparatus of shear rate accurately.
The utility model is a kind of full-automatic direct shear apparatus, comprises vertical load system and horizontal shear system, and described vertical load system comprises boosting frame, load sensor 2, afterburning hunting gear, shear box, electric pressing.Electric pressing is connected with the sill of boosting frame, drives boosting frame to move up and down.Boosting frame entablature connects load sensor, and shear box is placed in electric pressing top, and afterburning hunting gear is arranged on shear box top, and is positioned at load sensor below together with shear box.Described horizontal shear system comprises Vidacare corp, load sensor 7, pull bar, push rod, shear box.Described shear box and vertical load system are same shear box, and Vidacare corp is connected with shear box bottom by pull bar, and load sensor 7 is connected with shear box by push rod.
Described afterburning hunting gear comprises guide rail, slide block and pressure transmission plate.Described guide rail is fixedly connected with load sensor 2, and slide block is fixedly connected with pressure transmission plate, and pressure transmission plate is placed on shear box, and the relative guide rail of slide block slides.
Described electric pressing applies pressure at right angle.
Useful technique effect of the present utility model is: the utility model is saved manpower, has improved efficiency and test findings accuracy; Vertical load, shear rate can be set arbitrarily in specialized range, have met to greatest extent test needs.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model is a kind of full-automatic direct shear apparatus, comprises vertical load system and horizontal shear system.Described vertical load system comprises boosting frame 1, load sensor 2, afterburning hunting gear 3, shear box 4, electric pressing 5.Electric pressing is connected with the sill of boosting frame, drives boosting frame to move up and down.Boosting frame entablature connects load sensor, and shear box is placed in electric pressing top, and afterburning hunting gear is arranged on shear box top, and is positioned at load sensor below together with shear box.Described horizontal shear system comprises Vidacare corp 6, load sensor 7, pull bar 8, push rod 9, shear box 4.Described shear box and vertical load system are same shear box, and Vidacare corp is connected with shear box bottom by pull bar, and load sensor 7 is connected with shear box top by push rod.As shown in Figure 2, described afterburning hunting gear comprises guide rail 31, slide block 32 and pressure transmission plate 33.Described guide rail is fixedly connected with load sensor 2, and slide block is fixedly connected with pressure transmission plate, and pressure transmission plate is placed on shear box, and the relative guide rail of slide block slides, and adjusts the stressed position of sample in shear box.
Before on-test, soil sample is installed in shear box, sets the test parameterss such as pressure at right angle, shear rate.On-test,, vertical load system starts electric pressing, drags boosting frame descending, and the sample in shear box applies pressure at right angle, and according to the automatic controlled loading process of setting value, automatically judges stabilization.Then, start and shear control program, Vidacare corp pulls shear box bottom, and sample is implemented to shear.In shear history, by afterburning hunting gear, finely tune, adjust the stressed position of sample in shear box, keep pressure at right angle stable.In shear history, from motion tracking, control shear rate, voltage stabilizing, automatically gather shear displacemant, shear stress data, until stop shearing.After shearing finishes, the vertical load of automatic drawing unloading, resets shear box bottom, realizes direct shear test full-automatic.
In loading system, keep boosting frame motionless, promote shear box upwards, can apply pressure at right angle to the soil sample in shear box equally.In loading system, with cylinder (hydraulic cylinder), replace motor, with the interior compressed gas of microprocessor control cylinder (hydraulic cylinder) (liquid) body pressure, can realize automatic loading equally.In shear, as long as make shear box top and the bottom produce relative motion, promote (or pulling) upper (or under) shear box, all can realize the shearing to sample.Load and shear, both can adopt stepper motor, also can adopt the motor of adj sp.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
