Abstract
The invention relates to a guiding-antirotation-antifriction device for a shearing box. The guiding-antirotation-antifriction device is arranged on a shear testing instrument. The guiding-antirotation-antifriction device comprises antifriction steel balls or rolling needle bars, side guiding plates, antifriction steel balls or rolling needle bars, a rolling needle bar at the bottom of the shearing box, guiding plates of the shearing box, and guiding-antifriction steel balls or rolling needle bar of the shearing box, wherein the antifriction steel balls or rolling needle bars are arranged between two laminated rings; the side guiding plates are arranged at the two sides of an upper shearing box; the antifriction steel balls or rolling needle bars are arranged between the laminated rings and the side guiding plates; the rolling needle bar is arranged between a bottom plate of a lower shearing box and a bottom plate of the rolling needle bar; the guiding plates of the shearing box are arranged at the two sides of the bottom of the lower shearing box; the guiding-antifriction steel balls or rolling needle bar of the shearing box are arranged between the bottom of the shearing box and the guiding plates of the shearing box. The guiding-antirotation-antifriction device has the advantages that due to the design of the guiding plates, horizontal pushing force is buffered; sliding friction between the laminated rings and sliding friction between the shearing box and the bottom plate is changed into rolling friction by the antifriction steel balls or rolling needle bars, and the friction action can be obviously reduced; the degree of rolling friction can be calibrated by tests, so that the influence of the friction of the shearing box on a test result is finally eliminated.
Description
Technical field
The present invention relates to a kind of being arranged on and cut box guiding anti-rotation antifriction apparatus on shearing test apparatus.
Background technology
Shear test is in one of main experimental method of indoor test soil strength, the Shear Strength Index that is applicable to test most soil bodys.Large-scale direct shear test is generally used for testing the Shear Strength Index of the coarse grain soil body, and sample is often right cylinder or rectangular parallelepiped, and shear breakage is often circular or square.Shear box physical dimension is large, conducts oneself with dignity also large.In shear test, folded ring group (cutting box) is born horizontal thrust in normal force (vertical direction) effect, by horizontal thrust, make sample generation relative displacement, in shear box, sample had both born normal force, also bore horizontal shear force (gross load) and was sheared destruction.
Between folded ring (cutting box), between shear box and base plate all there is certain sliding friction effect in relative displacement, this sliding friction is larger than the needed horizontal thrust of sample shear failure by making to put on the horizontal thrust of shear box in test, and the size of this force of sliding friction is difficult to measure, therefore Soil Direct Shear process of the test is produced to the impact that is difficult to measurement, if do not consider rubbing action between box, will inevitably cause larger impact to test findings, reduce the degree of accuracy that Shear Strength Index is measured.
Summary of the invention
The object of the invention is to be improved according to the shortcoming existing in background technology and problem, provide a kind of simple in structure, significantly capable of reducing friction resistance cuts box guiding anti-rotation antifriction apparatus.
Technical scheme of the present invention is to provide a kind of box guiding anti-rotation antifriction apparatus of cutting, what be arranged on shearing test apparatus cuts box both sides, it is characterized in that: comprise the antifriction steel ball or the needle roller row that are arranged between two folded rings, be arranged on the side guide of cutting box both sides, be arranged on antifriction steel ball or needle roller row between folded ring and side guide, being arranged on down the box bottom needle roller of cutting of cutting between box plate and needle roller row base plate arranges, be arranged on down cut box two bottom sides cut box guide plate and be arranged on cut box bottom with cut between box guide plate cut box guiding antifriction steel ball or needle roller is arranged, wherein: side guide vertically props up the two sides of outside for cutting box on square, cut box guide plate and vertically prop up the two sides of outside for cutting box under square.
The present invention has the following advantages:
The design of guide plate is to move along the direction of its regulation for guaranteeing to cut box, horizontal thrust can not deflected, and antifriction steel ball or needle roller row become rolling friction by the sliding friction of folding between ring, cut between box and base plate, can reduce significantly rubbing action, and the size of rolling friction can be demarcated by test, finally eliminated the impact of shear box friction on test findings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the B portion enlarged drawing of Fig. 1.
Fig. 3 is the A portion enlarged drawing of Fig. 1.
Embodiment
From Fig. 1-2, the present invention includes the antifriction steel ball or the needle rollers row 10 that are arranged between two folded rings 9, be arranged on cut box both sides side guide 27, be arranged on antifriction steel ball or needle roller row 11 between folded ring 9 and side guide 27, be arranged on down and cut cutting box bottom needle roller row 37, be arranged on down and cut cutting box guide plate 35 and be arranged on lead antifriction steel ball or the needle roller of box of cutting of cutting box bottom and cutting between box guide plate 35 and arranging 36 of box two bottom sides between box plate 15 and needle roller row base plate 16, wherein:
Side guide 27 vertically props up the two sides of outside for cutting box on square, cuts box guide plate 35 and vertically props up the two sides of outside for cutting box under square.
The box guide plate 35 of cutting of the present invention is fixed on needle roller row base plate 16 by screw 38.
Design concept of the present invention:
The one, cut box guiding anti-rotation, the 2nd, capable of reducing friction resistance, take and reach that to reduce test error be object.
The design of guide plate is to move along the direction of its regulation for guaranteeing to cut box, and horizontal thrust can not deflected.In traditional shear test, generally all do not consider that cutting box is subject to the problem that can rotate after horizontal thrust.Thereby the design has increased side guide and cut box guide plate, make to cut box and can only move along the direction of its regulation, reached and prevented from cutting the object that box rotates.
At guide plate and cut and design steel ball between box or needle roller row becomes rolling friction by sliding friction, be the effective ways that reduce friction force.The present invention has also noticed the frictional resistance problem of cutting box and cutting box interlayer.For this reason, designed steel ball or needle roller and arranged to reduce its frictional resistance, both solved guiding problem, frictional resistance is also little, kills two birds with one stone.And the size of force of rolling friction is more stable, can demarcate by test for this reason, finally reach and eliminate the impact of shear box friction force on test findings.
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.
