Description
Technical field
This utility model relates to a kind of geotechnical centrifuge hanging basket pocket assembling device, particularly relates to a kind of high rotating speed geotechnique
Centrifugal basket pocket dress backlash eliminating equipment.
Background technology
Theoretical research is with engineering practice, and the attribute of jobbie studied by normal applications similar model.Geotechnique
In model test, with the non-linear plastoelastic soil body as object, carry out simulated gravity with centrifugal inertial force, improve
The similarity of model, can overcome soil indicator in Theoretical Calculation to suppose not to be inconsistent actual impact with simplifying, it is possible to
Reduce cost, time-consuming prototype measurement.Such model test, referred to as geotechnical centrifugal model test, produce
The equipment of raw inertia force is exactly geotechnical centrifuge.
In geotechnical centrifuge, hanging basket is important parts, and hanging basket is to place test model and install airborne setting
Standby platform.Hanging basket typically uses lifting mode, as it is shown in figure 1, hanging basket 1 is installed on the two of pivoted arm 3
End end, the arm 2 of hanging basket 1 uses hinge or bearing pin to be rotatably connected with pivoted arm 3.But it is near for operating in
Centrifugal basket under thousand g value centrifugal field, its working environment is abnormal harsh, hanging basket self overload especially severe,
Hanging basket is the biggest with the stress of pivoted arm junction simultaneously, and barrel structure and intensity are proposed the highest by these
Requirement, if still pressing lifting mode design and installation hanging basket, a lot of difficulty can be run into.
So, the geotechnical centrifuge of high-g level have employed one more reasonably hanging basket mounting means pocket
Dress, its principle is to be arranged on inside pivoted arm by hanging basket, utilizes pivoted arm end crossbeam carrying major part hanging basket load,
Concrete structure is as in figure 2 it is shown, the pocket that is respectively arranged at two ends with of pivoted arm fills inner chamber 4, and the arm 2 of hanging basket 1 fills with pocket
The cavity wall of inner chamber 4 uses hinge or bearing pin to be rotatably connected.
Pocket dress mode is used can preferably to solve the problem that in high speed geotechnical centrifuge, hanging basket stress is harsh, pocket
The key technology of dress mode is how before hanging basket gets rid of and puts down, it is ensured that have enough with pivoted arm end bottom hanging basket
Gap, makes hanging basket get rid of smoothly flat, eliminates when reaching certain rotating speed postscript bottom hanging basket and between pivoted arm crossbeam
Gap, when enabling centrifuge to work, hanging basket contacts with pivoted arm crossbeam so that pivoted arm can effectively carry
The load of hanging basket, thus ensure effectiveness and the safety of centrifuge that pocket fills.
Making a general survey of geotechnical centrifuge both domestic and external, the centrifuge using pocket dress mode is less, and main cause is centrifugal
The centrifugal acceleration of machine is not the highest, and lifting just can meet use requirement.Data shows, Japan is once at it
Centrifuge have employed pocket dress form, its structure as shown in Figure 3 and Figure 4, arm 2 He of its hanging basket 1
Bent axle 6 is used to connect between pivoted arm 3, the long section axle location of bent axle 6, control armed lever (unmarked in figure)
Connect firmly with bent axle 6, carry out push-and-pull respectively by a pair oil cylinder 5 and carry out band dynamic crankshaft 6 and rotate, it is achieved hanging basket 1
Outside contact internal walls with pocket dress inner chamber 4, it is achieved the gap that disappears function, wherein, bent axle 6, control armed lever and oil cylinder
5 collectively constitute hanging basket driving means.
Above-mentioned gap-eliminating structure uses eight oil cylinders 5, and its weak point is that structure is the most complicated, and cost is high, and wants
Realizing the control of the coordination to all oil cylinders 5 can be relatively difficult, controls difficulty big, and numerous and diverse structure is at height
Under centrifugal field system self will be by bigger centrifugal forces affect, no matter from installing safety and activity is the most reliable
Property, all may not adapt to the running environment of high centrifugal field.
Utility model content
The purpose of this utility model be that provide to solve the problems referred to above one be easy to application and cost relatively
Low high rotating speed geotechnical centrifuge hanging basket pocket dress backlash eliminating equipment.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of high rotating speed geotechnical centrifuge hanging basket pocket dress backlash eliminating equipment, is installed on the pivoted arm of geotechnical centrifuge,
The outer end of the described pivoted arm of horizontal direction is provided with pocket dress inner chamber, and the arm of hanging basket is rotatably connected in institute by bearing pin
Stating in the cavity wall of pocket dress inner chamber, the cavity wall of described pocket dress inner chamber is provided with " u "-shaped mouth and its outer end opening, institute
Stating bearing pin and pass described " u "-shaped mouth, the outer end of described " u "-shaped mouth is provided with vertical leaf spring, described plate
The upper/lower terminal of spring is respectively arranged in the cavity wall of described pocket dress inner chamber.
In said structure, the structure of " u "-shaped mouth and leaf spring is most important innovation structure, when hanging basket is in quiet
Only during the i.e. plumbness of state, to bear hanging basket weight in the bearing pin of installation hanging basket is placed in " u "-shaped mouth and by pivoted arm
Power, leaf spring plays the effect spacing to bearing pin；After pivoted arm rotates, start to rotate at hanging basket and do not rotate to water
During Ping, the centrifugal action being subject to of basket is in leaf spring, and now leaf spring generation elastic deformation also makes hanging basket
Microspur moves outward；Hanging basket is rotated in place and during basic horizontal, and hanging basket moves into place outward and fills with pocket
The outside cavity wall of inner chamber completely attaches to, thus eliminates outside hanging basket and pocket dress inner chamber the gap between cavity wall, makes
Most of centrifugal force of hanging basket is born by pivoted arm, i.e. utilizes pivoted arm crossbeam carrying major part hanging basket load,
Realize the purpose of safe operation.
As preferably, the upper end of described leaf spring is provided with circular port, and the lower end of described leaf spring is provided with waist-shaped hole, many
Individual installation screw is each passed through after the circular port of described leaf spring and waist-shaped hole with the cavity wall of described pocket dress inner chamber even
Connect.The effect of waist-shaped hole is to make leaf spring have certain deformation space when oppressed, is located at by waist-shaped hole
It is from bottom to top that lower end is because the rotation of hanging basket, and it is also trend from bottom to top to the pressure of leaf spring,
So the lower end of leaf spring can firstly there are Deformation Demands.
Specifically, the cavity wall of described pocket dress inner chamber is provided with installation cavity, and a described hanging basket includes that two are hung
Arm, each described arm is installed in a described installation cavity body, on the cavity wall of described installation cavity both sides
Being equipped with described " u "-shaped mouth, the two ends of described bearing pin are each passed through two described " u "-shaped mouths of correspondence,
Outer end all correspondences of each described " u "-shaped mouth are provided with a described leaf spring.
The beneficial effects of the utility model are:
This utility model uses the structure that the " u "-shaped mouth on pivoted arm and leaf spring coordinate, and utilizes the deflection of leaf spring
Eliminating the gap bottom hanging basket and between pivoted arm in hanging basket pocket packing technique, structure compares traditional oils cylinder structure more
Add simple, and carry out manual control without offseting gap process, prior art need only be utilized the parameter of leaf spring and
Installation site carries out careful design can realize the gap purpose that disappears, easy to use and cost is relatively low, it is simple to promote.
