Abstract
The utility model relates to a kind of anti-device that sticks up of box of cutting, symmetrical being arranged on shearing test apparatus, it is characterized in that the anti-appliance stand that sticks up comprises base and is vertically welded in the middle anti-piece that sticks up of base, base and anti-sticking up arrange reinforcement between piece, base is fixed on curb girder by support gib screw, the anti-piece that sticks up is by preventing that sticking up lock screw is horizontally fixed on the stacked ring of top, and anti-sticking up between piece and top stacked ring left gap.The utility model is simple in structure, and physical strength is high; Can effectively solve in shear test process and cut the problem that box tilting tilts, improve test accuracy.
Description
Technical field
The utility model relates to a kind of anti-device that sticks up of box of cutting.
Background technology
Shearing test apparatus, for measuring native shearing strength, adopts soil sample under different vertical pressure conventionally, applies horizontal force and shears the shear stress while destroying in the hope of shear surface, then according to Coulomb law, determines native shear strength parameter.Actual while carrying out shear test to cutting box level while exerting pressure, because the rolling of shear surface soil sample particle causes after shear box stand under load slightly perk, tilt, cause test instrument measuring accuracy to reduce.
Tradition direct shear apparatus is cut box top infinite place mechanism, very easily cuts the problem that box is upturned in process of the test.Have a strong impact on results precision.Large-scale coarse-grained soil equipment particularly, because soil sample particle is large, during test particle rolling distortion cause upwarp more serious.How addressing this problem, improving measuring accuracy is central topic of the present invention.
Summary of the invention
The purpose of this utility model is improved according to the shortcoming existing in background technology and problem, and providing a kind of can prevent sticking up device by the box of cutting simple in structure, that physical strength is high.
The technical solution of the utility model is a kind of anti-device that sticks up of box of cutting of structure, symmetrical being arranged on shearing test apparatus, it is characterized in that: comprise anti-picking device support, the anti-appliance stand that sticks up comprises base and is vertically welded in the middle anti-piece that sticks up of base, base and anti-sticking up arrange reinforcement between piece, base is fixed on the curb girder of left and right by support gib screw, the anti-piece that sticks up is by preventing that sticking up lock screw is horizontally fixed on the stacked ring of top, the top stacked ring of horizontal positioned is limited on initial position, and anti-sticking up between piece and top stacked ring left gap.
The utlity model has following advantage and beneficial effect:
1, simple in structure, physical strength is high;
2, can effectively solve in shear test process and cut the problem that box tilting tilts, improve test accuracy;
3, solved the defect of prior art, designed lightly easyly, reinforced the location of cutting box, made whole test instrument more firm.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the C portion enlarged drawing of Fig. 1.
Embodiment
Known according to Fig. 1-2, the utility model is symmetrical to be arranged on shearing test apparatus, comprise the anti-appliance stand 1 that sticks up, the anti-appliance stand 1 that sticks up comprises base 6 and is vertically welded in the middle anti-piece 7 that sticks up of base 6, base 6 and anti-sticking up between piece 7 arrange reinforcement, base 6 is fixed on curb girder by support gib screw, and the anti-piece 7 that sticks up is by preventing that sticking up lock screw 2 is horizontally fixed on top stacked ring 4, and anti-sticking up between piece 7 and top stacked ring 4 left gap.
Reinforcement described in the utility model is one to be arranged on base 6 and the anti-one section of right-angled trapezium joint face that sticks up junction, right angle between piece 7.
The utility model design concept:
Preventing from cutting box, to upwarp preferably the simplest way be that a position-limit mechanism is set, and stops to cut box and upwarp.The utility model will anti-stick up cleverly device and be arranged on that to apply the left and right curb girder (column) of normal force framework upper, and frame rigidity is good, substantially without being out of shape, can effectively limiting, cut box and will tilt upward.Because on to cut box (top stacked ring) be (during the shearing promote lower box) of not moving, for this reason, pickproof mechanism needn't be considered friction problem.As long as guaranteeing position-limit mechanism itself cuts box and upwarps without being out of shape, just can limiting.So, cutting planar design adjustable limit screw on box, just solved problem.
Embodiment described in the utility model is only the description that preferred implementation of the present utility model is carried out; not the utility model design and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various modification and improvement that in this area, engineering technical personnel make the technical solution of the utility model; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection, is all documented in claims.
