Description
Technical field
The utility model relates to a kind of frozen soil direct shear test instrument auxiliary device, especially can make that frozen soil is box-packed to be unloaded mobile light, laborsaving, facilitates frozen soil sample to make, makes frozen soil box precisely in place, and the box-packed handler of frozen soil that energy available protecting soil sample is not damaged.
Background technology
At present, known frozen soil direct shear test instrument adopts frozen soil box to carry out refrigerant circulation cooling to soil sample usually, for improving frozen soil box to the cooling-down effect of soil sample, it is box-like that frozen soil box adopts double-deck copper coin to be made into, between native box side and the double-deck copper coin of bottom surface, arrange that roundabout copper pipe is in order to carry out refrigerant circulation cooling, outside double-deck copper coin, be close to poriness insulation material, insulation material is wrapped to form frozen soil box shell by outermost layer stainless sheet steel.This kind of frozen soil box not only freezes and high insulating effect, also has large, firm, the resistance to advantage of waiting so long of rigidity, but owing to using the larger metal material of copper, stainless steel isodensity to make in a large number, makes the overall weight of this kind of frozen soil box bigger than normal, be generally 50 ~ 60Kg.The overweight one side of soil box makes manually to load and unload native box and becomes very difficult, cannot complete native box charge and discharge operations without enough physical laboratory technician; On the other hand owing to being difficult to once precisely be located in frozen soil direct shear test instrument horizontal rail when native box is crossed and re-mounted native box, soil sample is easily made to touch shear plate and cause soil sample to destroy when repeatedly adjusting native box position.
Summary of the invention
Box-packedly unload difficulty for overcoming existing frozen soil direct shear test instrument frozen soil, not easily precisely in place, soil sample such as to be easily damaged at the deficiency, the utility model provides a kind of frozen soil direct shear test instrument frozen soil box-packed handler, its entirety is fixed in frozen soil direct shear test instrument frame, integral demounting can be facilitated according to test needs, do not affect the former using function of frozen soil direct shear test instrument, by roller, track, thin-walled lifting jack, lift the devices such as support and make the lifting of frozen soil box, mobile become very light, facilitate soil sample to make, and frozen soil box can be made precisely in place.
When using the box-packed handler of this frozen soil, frozen soil box is placed in connect lifting jack lift on support, because thin-walled lifting jack is fixed on base plate skeleton, base plate skeleton supporting is on roller, roller can along non-orbiting scroll, therefore frozen soil box can be made along track easily movement outside direct shear apparatus, until limited bolt position, outside stops automatically, do not need to unload frozen soil box direct layering dress soil sample.Be cooled to after design freezing temperature until soil sample, by frozen soil box along track to direct shear apparatus medial movement, until inner side limiting-position bolt position stops automatically, open hydraulic oil pump oil return valve; thin-walled lifting jack bounce back; drive lift frozen soil box support decline, frozen soil box is declined thereupon and with the accurate close contact of frozen soil direct shear test instrument horizontal rail.When the backing positions lifting frozen soil box continues to reduce, lift support and be separated with frozen soil box, now can fill soil sample position by lifting support along rail moving to outermost, loading and start shear test after temperature stabilization.After shear test terminates, support will be lifted and move to inner side frozen soil box clipped position again along track, close hydraulic oil pump oil return valve, the jacking of thin-walled lifting jack is made by pressing hydraulic oil pump handle, thus drive and lift support and rise, lift support and lift frozen soil box and rise together, and frozen soil box is separated with frozen soil direct shear test instrument horizontal rail, support will be lifted after to be separated again and fill soil sample position together with frozen soil box along rail moving to outermost, removal soil sample.Repeat above-mentioned steps and carry out shear test next time.
The beneficial effects of the utility model are; the handling of frozen soil direct shear test instrument frozen soil box, mobile more light, laborsaving can be made, facilitate frozen soil sample to make, frozen soil box can be made precisely in place; and can available protecting soil sample not be damaged, and do not affect the former using function of frozen soil direct shear test instrument.
