Abstract
The invention relates to an anti-upwarp device for a shear box. The anti-upwarp device is mounted on a shear tester in a bilateral symmetry manner. The anti-upwarp device is characterized in that an anti-upwarp device bracket comprises a base and an anti-upwarp block perpendicularly welded in the middle of the base, wherein reinforcement ribs are arranged between the base and the anti-upwarp block; the base is fixed on a side beam through a bracket fixing screw; the anti-upwarp block is horizontally fixed on a top layer stacking ring through an anti-upwarp block; a clearance is reserved between the anti-upwarp block and the top layer stacking ring. The anti-upwarp device for the shear box is simple in structure and high in mechanical strength; the problem that the shear box is upwarped and tilted in the shear test process in the prior art can be effectively solved, and the test precision is improved.
Description
Technical field
The present invention 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 object of the invention is to be improved according to the shortcoming existing in background technology and problem, providing a kind of can prevent sticking up device by the box of cutting simple in structure, that physical strength is high.
Technical scheme of the present invention 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 present invention has the following advantages 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 structural representation of the present invention.
Fig. 2 is the C portion enlarged drawing of Fig. 1.
Embodiment
Known according to Fig. 1-2, the present invention 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 of the present invention 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.
Design concept of the present invention:
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 present invention will anti-be stuck up cleverly device and will 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 of the present invention is only the description that the preferred embodiment of the present invention is carried out; not design of the present invention and scope are limited; do not departing under the prerequisite of design philosophy of the present invention; various modification and improvement that in this area, engineering technical personnel make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection, is all documented in claims.
