Specific embodiment
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is carried out clearly
Chu, it is fully described by.
See also Fig. 1 and Fig. 2, a kind of fixing device of ballast that the specific embodiment of the invention provides.Need
Illustrate, the direction all around mentioned in the present invention is all fixed with residing direction all around during ballast working condition
Justice, that is, under normal circumstances, the one side that ballast fixing device is close to installed surface (metope) is below, on the other side for above,
So that it is determined that the direction all around of ballast and its fixing device.
As shown in figure 1, ballast fixing device includes: box body of ballast 12, it is provided with use in its inner cylindrical cavity
In placing the square groove component 13 with fixed-ballast 8, in cylindrical cavity, ballast 8 each side arranges buffering dress
Put, voussoir fixed component is set in the back or front of ballast 8.
Described voussoir fixed component and square groove component 13 are for fixed-ballast in the longitudinal direction, tight using voussoir
Solid principle make ballast fore-and-aft direction fasten.Specifically, voussoir fixed component includes voussoir 9, lower wedge block 10 and lock
Tight screw 11.As illustrated in fig. 1 and 2, voussoir fixed component is arranged at ballast rear, and upper voussoir 9 becomes " 7 " font, described hyposphene
Block 10 top, near upper voussoir 9 one STH, is inserted for lock-screw 11, square groove component 13 include the first end wall, second
End wall and bottom, specifically the first end wall is antetheca, and the second end wall is rear wall, and its antetheca and ballast 8 front end are against bottom
Contact with ballast 8 bottom, in bottom, hollow cylinder 14 is set with rear wall intersection, when ballast assembles, upper voussoir 9 is set
It is placed in the rear portion of ballast 8, the top of upper voussoir 9 is abutted with ballast 8 upper surface, after the side wall of upper voussoir 9 and ballast
End is arranged on voussoir 9 rear against, lower wedge block 10, and its antetheca and upper voussoir 9 side wall are against, its rear wall and square groove component 13
Rear wall is against because the presence of hollow cylinder 14, the bottom of lower wedge block 10 and hollow cylinder 14 end are arranged at square groove component 13 bottom
Portion contacts, and the equal inwall of perforate of hollow cylinder 14 and lower wedge block 10 has threaded screw, passes through lower wedge block by lock-screw 11
Perforate on 10 penetrates in hollow cylinder 14 always, then tightens lock-screw 11, you can by voussoir fixed component and side
Ballast is fixed by shape groove component 13 in the longitudinal direction.
For clearly describing the surface of ballast all directions, the surface of fore-and-aft direction is referred to as holding, as one end is front end,
Other end rear end, left and right directions is referred to as side, and that is, side is left side, and opposite side is right side.In the fixing device of ballast,
The left and right sides of ballast is respectively provided with a buffer unit.As illustrated in fig. 1 and 2, schematically illustrate and set on the right side of ballast 8
The structure of the buffer unit put, equally can arrange an identical buffer unit in the left side of ballast.
The structure of specific buffer unit refers to Fig. 3 and Fig. 4 in the lump, and described buffer unit includes: top board 1, elastomeric element 2
With fixed plate 4, wherein elastomeric element 2 one end is fixed on top board 1, and this end is resisted against on top board 1, and the other end is resisted against fixed plate
On 4.Top board 1 passes through stop screw 7 and nut is connected with fixed plate 4, and fixed plate 4 is fixed on box body of ballast 12, specifically,
It is provided with floor on fixed plate 4 side wall, by connector, described floor is fixedly connected with described casing, specifically, passes through
Buffer unit is fixed on box body of ballast 12 for fixing screws 5 and packing ring 6.
As shown in 3 and Fig. 4, top board 1 is made up of side wall, antetheca, rear wall, and its side wall offers rectangular through-hole and ballast 8
Adjacent, its antetheca and rear wall offer the spacing screw 15 of two ellipses, the specifically enlarged drawing of spacing screw such as Fig. 5 respectively
Shown.Fixed plate 4 is made up of side wall, antetheca, rear wall, its antetheca and rear wall offer respectively two with top board 1 on ellipse
The oval spacing screw of the spacing screw of shape 15 identical, stop screw 7 passes through top board 1 upper limit screw 15 and corresponding solid
Spacing screw in fixed board 4 simultaneously nut 3 is fixed on stop screw 7, thus top board 1 is connected with fixed plate 4.Wherein nut
3 are unable to overtorquing, to allow stop screw 7 can carry out a range of displacement in oval spacing screw 15, concrete and
Speech is it is allowed to stop screw 7 can be displaced to the other end from one end of oval spacing screw 15 major axis.
When ballast and its fixing device fall, for example, turn right when falling, ballast 8 is subject to impulsive force to the right
To be subjected to displacement to the right, ballast 8 by extrude its on the right side of buffer unit top board 1, due to spacing in top board 1 front and back walls
Screw 15 is ellipse, and this oval long axis direction is left and right directions, and fixed plate 4 can occur moving to right of certain displacement amount, should
In the mobile range that ballast allows, then, top board 1 extrudes elastomeric element 2 to displacement, and elastomeric element 2 deforms, and makes
Impulse force suffered by ballast 8 drastically reduces, and stops further displacement to the right, thus the Bit andits control of ballast is being allowed
Smaller range in.
On ballast 8 left side, same buffer unit is also installed, thus equally can be hard to bear when ballast falls to the left
To the effect of buffer unit, absorb the impulsive force to the left that ballast 8 is subject to, stop ballast from producing do not allow larger to the left
Displacement.
Elastomeric element 2 preferably employs spring, it would however also be possible to employ other elastomeric elements such as resilient rubbber cushion.
Fixed plate 4 can also adopt other conventional fixed forms of this area, such as bolt with the fixed form of casing 12
Fixing etc., will not be described here.
It should be noted that for the profile of rectangle protrusion in two sides about common ballast, top board side wall arranges and is somebody's turn to do
Protrude the rectangular channel of coupling, so that the projecting surface of ballast enters in the cavity being surrounded by top board 1 and fixed plate 4, save volume.
For various sizes of ballast it is only necessary to design various sizes of top board.If ballast employs some distinctive appearances,
Only need to change the profile of top board accordingly.For the ballast that weight is larger, in order to ensure enough cushion effects it is only necessary to
Change elastomeric element.
By arranging buffer unit, the fixing reliability of fixing device of the present invention, structure are simple.Easy to operate, energy
Enough control the left and right displacement distance of ballast, make the movement of ballast in allowed limits, it is to avoid destroy left and right top board, effectively
Ensure that the security of ballast.
The above is the preferred embodiment of the present invention it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
