Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
Referring to figs. 1 through Fig. 3, the present embodiment relates to solidified earth direct shear apparatus, comprise base 1, slidably be located at the lower box body 2 on base 1, and the upper cartridge body 3 be located on lower box body 2, described upper cartridge body 3 has through hole 31, and described lower box body 2 has slotted eye 21, described through hole 31 is connected with described slotted eye 21; Rolling mechanism is provided with between described base 1 and lower box body 2, described rolling mechanism comprises the limiting plate 42 on ball 41 and the described base 1 of fixed installation, described limiting plate 42 has the arc groove 421 for placing described ball 41, and described arc groove 421 has the through hole 31 running through described limiting plate 42; One end of described ball 41 contacts with described base 1, stretch out described through hole 31 outside the other end; The diameter of described through hole 31 is less than the diameter of ball 41.When shearing measures, first upper cartridge body 3 and base 1 are fixed, and then the solidified earth after the demoulding is put into described through hole 31 and slotted eye 21, next step, the wheel shaft adopting constant speed to advance applies horizontal applied force on lower box body 2, make lower box body 2 carry out horizontal slip relative to upper cartridge body 3 under the guiding of ball 41, thus solidified earth is sheared.In the process that ball 41 rotates, ball 41 can only rotate in situ under the constraint of limiting plate 42, can not move with lower box body 2 and slide, the situation preventing ball 41 to come off from the both ends horizontal of base 1 occurs, and the diameter due to through hole 31 is less than the diameter of ball 41, make ball 41 can not deviate from from vertical direction further, thus ensure that the stability that ball 41 works and reliability.
The bottom surface of described lower box body 2 has groove 22, and the external part of described ball 41 snaps in described groove 22.Under the constraint of groove 22, groove 22 makes lower box body 2 can only do rectilinear motion along the direction of ball 41 with coordinating of ball 41, prevents lower box body 2 from deviating from base 1.
As shown in Figure 4, described lower box body 2 is provided with the top board 5 running through described slotted eye 21, and the two sides of described lower box body 2 are stretched out at the two ends of described top board 5; Concrete, described top board 5 comprises the section of ejecting 51 be slidably installed in described slotted eye 21, and hinged with the described section of ejecting 51 two ends respectively two in one end press section 52, and the other end of described pressing section 52 stretches out described lower box body 2.After solidified earth being cut off, by applying downward pressure to pressing section 52, pressing section 52 drives the section of ejecting 51 to move upward, and rapidly the residual solidified earth in lower box body 2 can be ejected, be very easy to the cleaning of lower box body 2 inside.
Described lower box body 2 comprises outter box 23 and is fixedly installed in the inner box 24 of outter box 23 inside, and described slotted eye 21 is located on inner box 24, and described upper cartridge body 3 is located on inner box 24, and described through hole 31 is connected with described slotted eye 21.The upper surface of described inner box 24 and the upper end surface of described outter box 23 are in same level.
In order to make the water in through hole 31 and slotted eye 21 can discharge from by Water permeable body downwards, the described slotted eye 21 be positioned on described top board 5 is provided with the Water permeable body 6 that can slide along slotted eye 21.
Measured carrying out shearing to solidified earth, the conveniently taking-up of upper cartridge body 3, described inner box 24 is provided with handle 7, by holding handle 7, rapidly inner box 24 can be separated dismounting with outter box 23.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
