Abstract
The utility model relates to a kind of being arranged on and cuts box guiding anti-rotation antifriction apparatus on shearing test apparatus.The utility model comprises the antifriction steel ball or the needle roller row that are arranged between two folded rings, be arranged on cut box both sides side guide, be arranged on antifriction steel ball or needle roller row between folded ring and side guide, be arranged on down and cut cutting box bottom needle roller row, be arranged on down and cut cutting box guide plate and be arranged on and cutting box bottom and arrange with lead antifriction steel ball or the needle roller of box of cutting of cutting between box guide plate of box two bottom sides between box plate and needle roller row base plate.The design of the utility model guide plate has cushioned horizontal thrust, and the sliding friction of folding between ring, cut between box and base plate is become rolling friction by antifriction steel ball or needle roller row, can reduce significantly rubbing action, and the size of rolling friction can be demarcated by test, finally eliminate the impact of shear box friction on test findings.
Description
Technical field
The utility model relates to a kind of being arranged on and cuts 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, make sample generation relative displacement by horizontal thrust, 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 purpose of this utility model is improved according to the shortcoming existing in background technology and problem, provide a kind of simple in structure, significantly capable of reducing friction resistance cut box guiding anti-rotation antifriction apparatus.
The technical solution of the utility model is to provide one and cuts box guiding anti-rotation antifriction apparatus, 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 utlity model has following advantage:
The design of guide plate is for ensureing that cutting box moves along the direction of its regulation, horizontal thrust can not be deflected, and the sliding friction of folding between ring, cut between box and base plate is become rolling friction by antifriction steel ball or needle roller row, can reduce significantly rubbing action, and the size of rolling friction can be demarcated by test, finally eliminate the impact of shear box friction on test findings.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
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 utility model comprises 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 cut 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 described in the utility model is fixed on needle roller row base plate 16 by screw 38.
The utility model design concept:
The one, cut box guiding anti-rotation, the 2nd, capable of reducing friction resistance, reduces test error as object to reach.
The design of guide plate is for ensureing that cutting box moves along the direction of its regulation, can not deflect horizontal thrust.In traditional shear test, generally all do not consider that cutting box is subject to the problem that can rotate after horizontal thrust.Make to cut box and can only move along the direction of its regulation thereby the design has increased side guide and cut box guide plate, reached and prevented from cutting the object that box rotates.
At guide plate and cut and design steel ball between box or sliding friction is become rolling friction by needle roller row, be the effective ways that reduce friction force.The utility model has also been noticed the frictional resistance problem of cutting box and cut 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 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 of the utility model request protection, has all been documented in claims.
