Embodiment
Invention is described in detail below in conjunction with the accompanying drawings.
The structure of servicing unit provided by the invention suitable for geotechnical centrifuge model dress sample as shown in Figure 1, Figure 2, Fig. 3 and Fig. 4
Shown, the servicing unit includes slide plate 1, slide rail 2 and support 3 and limiter.
Slide plate 1 includes the panel 22 and four pulleys 20 of square, and the center of panel 22 is provided with circular hole 21, the axis of circular hole 21
Being overlapped with the axis of the vertical direction of panel 22, four pulleys 20 are respectively arranged on four angles of the bottom surface of panel 22, and four
Pulley 20 is centrally located on same four square angles, and the square is centrally located at the axis of panel vertical direction
On, as shown in Figure 5.It should be noted that the diameter of circular hole is more than the diameter of the lifting platform of triaxial apparatus 5 and is less than the straight of balancing gate pit 4
Footpath.In the present embodiment, the length of side of plate face is 720mm, thick 30mm, a diameter of 300mm of circular hole, a diameter of 50mm of pulley, is slided
The distance of the center of wheel to plate face bottom surface is that the distance between 75mm, adjacent pulleys is 660mm.
Slide rail 2 has two, and the both ends of each slide rail 2 are sealed, and the cross section of the groove in each slide rail 2 is in inverted trapezoidal shape,
The width of bottom portion of groove is equal to the thickness of pulley, it should be noted that groove will have enough bottom width and gradient, Neng Gourong
Perhaps pulley slides in groove.In the present embodiment, the length of slide rail is 1490mm, width 60mm, is highly 30mm, groove
Length is 1430mm, and the long 40mm in upper bottom of groove cross section, go to the bottom long 20mm, upper 60 degree of base angle, lower 120 degree of base angle.
Support include column A6, column B7, column C8, column D9, column E10, column F11, crossbeam A12, crossbeam B13,
Crossbeam C14, crossbeam D15, crossbeam E16, crossbeam F17, web beam A18 and web beam B19.Column A6, column B7, column
C8, column D9, column E10, column F11 shape and size are identical, crossbeam A12, crossbeam B13, crossbeam C14, crossbeam
D15, crossbeam E16, crossbeam F17 shape and size are identical, and web beam A18, web beam B19 shape and size are complete
It is exactly the same.Column A6 and column B7 is welded in the both ends of one of slide rail bottom, and column C8 and column D9 are welded in another
The both ends of slide rail bottom, crossbeam A12 are fixed on two slide rails and are located between the one end of the same side, and crossbeam B13 is fixed on two slide rails
Between the other end of the same side, so not only ensure that two slide rails 2 are horizontally disposed and are parallel to each other, and can ensure that two
The opening of slide rail 2 is upward.Further to reinforce two slide rails 2, following measures are taken：By column E10 and column F11 respectively symmetrically
Ground is welded on the centre position of two slide rails, and crossbeam C14 is added between two slide rail middle parts, column 6A's and column D9
Crossbeam D15 is added between bottom, crossbeam E16 is added between column E10 and column F11 bottom, in column B7 and column C8
Bottom between add crossbeam F17, web beam A19 is added between column A6 and column E10 bottom, in column F11 and
Web beam B18 is added between column D9 bottom, while ensures web beam A19, web beam B18, crossbeam D15 and crossbeam
E16 forms quadra, and crossbeam C14, crossbeam E16, column E10 and column F11 form quadra；Take these measures it
Afterwards, two slide rails just become to consolidate very much under the support of support.Due to also to place the lifting platform of triaxial apparatus below two slide rails, and
And the position of triaxial apparatus lifting platform can not be located at immediately below slide plate, otherwise it is not easy to fill sample, therefore column E must be made to column A's
Distance is greater than column E to column B distance, so that column E and column B distance is more than the width of triaxial apparatus lifting platform,
And then the lifting platform of triaxial apparatus is very easily positioned over below two slide rails (between column E and column B), it is wrong with the position of slide plate
Open.In the present embodiment, column A, column B, column C, column D, column E, column F length are 600mm, the length of its cross section
For 60mm, width 30mm, crossbeam A, crossbeam B, crossbeam C, crossbeam D, crossbeam E, crossbeam F length are 600mm, its cross section
Length is that 30mm, width 30mm, web beam A and web beam B length are 600mm, and the length of its cross section is 60mm,
Width is 30mm.
Two of which pulley 20 is located in one of in slide rail 2, and two other pulley 20 is located in another slide rail, four
Pulley can be slidably in the slide rail where respective.
Limiter has two, and limiter includes limiter body 23, the bolt 26 of neck 24 and two, and limiter body 23 is in length
Cube shape, is provided with the neck 24 to match with slide rail on limiter body 23 in the width direction, the shape of the cross section of neck 24 with
The shape of the cross section of slide rail 2 it is mutually disorderly and, symmetrically offer screwed hole A25 on the two side of neck 24, two bolts 26 are respectively with two
Screwed hole A25 is threadedly coupled, and corresponding opening position symmetrically offers screwed hole B27 on each two side of slide rail 2.The present embodiment
In, limiter body length is 70mm, width 30mm, is highly 40mm.
The material of panel 22, slide rail 2 and support 3 is made using steel panel, and whole device is not only cheap,
And resistance to compression, wear-resisting and damage tolerant ability are strong.
The application method of servicing unit provided by the invention suitable for geotechnical centrifuge model dress sample is as follows：
1) before sample is filled, slide plate is slided into the opening position contacted with crossbeam A, the lifting platform of triaxial apparatus is positioned over two slide rails
Lower section (i.e. between column E and column B and between column C and column F), the lifting platform of slide plate and triaxial apparatus is set to stagger placement；
2) adjust the relative position of servicing unit and triaxial apparatus, it is ensured that when slide plate slides to ensure when slide plate slides to
During the position of crossbeam B interior side contacts, the axis of triaxial apparatus lifting platform and the axis of slide plate are on the vertical straight line of same；
3) base of balancing gate pit is moved on slide plate, adjusts the relative position for increasing base and slide plate, make the axis of balancing gate pit
It is located at the axis of slide plate on the vertical straight line of same, uses mould sample preparation on base top, balancing gate pit top is placed on
Through making excellent pressure chamber base over-assemble into complete balancing gate pit, then promote slide plate slides to crossbeam B interior side contacts
Opening position, now the axle center of balancing gate pit and the axle center of triaxial apparatus lifting platform are on the vertical straight line of same；
4) two limiters are stuck on two slide rails, position of two limiters of adjustment on two slide rails, make panel card
Between crossbeam B and two limiters, then two bolts are screwed into two screwed hole B respectively (position of screwed hole can be according to panel
The position of the length of side and screwed hole on the stopper is determined) in, two limiters are separately fixed on two slide rails, so that will
Panel is fixed, and avoids panel from back sliding and (slided toward the direction towards crossbeam A)；
5) starting triaxial apparatus makes lifting platform slowly rise, and lifts to rise to by balancing gate pit behind contact room and is popped one's head in pressurization
Joint, so far entirely dress sample step is completed.
