Axis is rotatably arranged on driving box, and swing handle is connected on driving shaft.
It is provided with two adjacent driving gears on the driving shaft, two sliding teeth are arranged at intervals in driven shaft
Wheel is provided with the shift fork for stirring shifting slide gear movement on driving box.
The good effect of the utility model is：The utility model simultaneously acts on supporting plate by two jack, will
Supporting plate lifts, and is lifted airframe using mop, reliable and stable, can improve safety coefficient, while having felt on supporting plate,
On the one hand it on the other hand can prevent supporting plate from generating scuffing to fuselage surface with damping.The utility model passes through one group of driving
Device drives two jack effects, two jack to rise or fall simultaneously simultaneously, and synchronism is very good.It is very heavy using spiral
Top, it is simple in structure, it can be achieved that self-locking, effectively prevent falling after rise when propping up weight.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the left jack structure schematic diagram of the utility model；
Fig. 3 is the utility model inner sleeve structure schematic diagram；
Fig. 4 is the utility model driving device structure schematic diagram.
Specific implementation mode
As shown in Fig. 1, the utility model include A-frame 1, the stull 11 that is arranged between two A-frames 1,
The supporting plate 4 that jacking apparatus on two A-frames 1 is set and is arranged on jacking apparatus, 4 top surface of the supporting plate
Shape is adapted with the bottom shape of aircraft, and felt is equipped on supporting plate 4.The jacking apparatus includes being separately positioned on two
Left jack 3 on the A-frame 1 and right jack 6.
As shown in Fig. 2 to 4, the left jack 3 is identical with 6 structure of right jack and is oppositely arranged on two described three
In angle support 1, driving device is provided between left jack 3 and right jack 6.The left jack 3 include cylinder 301,
The inner sleeve 302 and be arranged outside that the outer sleeve 304 being arranged in cylinder 301 is connected through a screw thread with 304 upper end of outer sleeve
The bevel gear 306 of 304 lower end of sleeve is provided with annular snap-gauge 305, in the cylinder 301 in the lateral wall of the outer sleeve 304
Inside it is provided with annular slot compatible with the annular snap version 305；It is provided in an axial direction in the lateral wall of the inner sleeve 302
The card slot 307 of setting is provided with bayonet lock 303 compatible with the card slot 307, the bevel gear 306 in the cylinder 301
It is sequentially connected with driving device.Outer sleeve 304 is erected at by annular snap version 305 in cylinder 301, under the action of driving device
It rotation, inner sleeve 302 can be spirally connected by screw thread with outer sleeve 304 in cylinder 301, and inner sleeve 302 is in card slot 307 and card
Under the action of pin 303, inner sleeve 302 can only be carried out vertically mobile and cannot be rotated, then when outer sleeve 304 rotates
When, inner sleeve 302 can only upper and lower translation, realization weight is moved up and down.Two-half structure may be used in cylinder 301,
Inner sleeve 302 and outer sleeve 301 are fastened inside it.Simple, the reasonable design using the jack structure of this structure, and tie up
It repaiies conveniently.
The driving device includes driving box 14, is rotatably arranged in driving box 14 driving shaft 7 is driven with driving shaft 7
The driven shaft 10 of connection and driving bevel gear 11 at 10 both ends of driven shaft is set, the driving bevel gear 11 and bevel gear
306 are meshed, and the driven shaft is rotatably arranged on driving box 14, and swing handle 13 is connected on driving shaft 7.In the master
It is provided with two adjacent driving gears 8 on moving axis 7, two shifting slide gears 9 are arranged at intervals in driven shaft 10, in driving box 14
On be provided with for stir shifting slide gear 9 movement shift fork.By the way that shifting slide gear 9 is arranged, can adjust driving shaft and driven shaft it
Between rotating ratio, realize that different jack is regulated the speed, when supporting plate 4 apart from airframe farther out when may be used faster from
Moving axis velocity of rotation makes supporting plate 4 quickly close to fuselage.And when supporting plate 4 is closer apart from fuselage, it is changed to slower velocity of rotation,
Keep supporting plate 4 slowly close, the reduction supporting plate 4 of maximum possible of damage can be with to(for) fuselage.
