Specific embodiment
The adjustable wheel holding frame of helicopter tractor of the present invention is described in further detail with reference to Fig. 1 to Fig. 5.
As depicted in figs. 1 and 2, the adjustable wheel holding frame of helicopter tractor of the present invention, including framework A1, framework
B2, fixing axle 3, limited block 5, bearing pin 6, spring catch 8, disk roller 9.
Wherein, framework A1 and framework B2 include two side walls and by two reinforcing plates of side walls connection respectively, side wall and plus
It is welded between strong plate；The distance of two sides wall outer face of framework A1 is less than two distances of side wall inner face of framework B2,
Outside the end of framework A1, the two is in close contact the end sleeve of framework B2；Fixing axle 3 overlaps portion through framework A1 and framework B2
The side wall for dividing, framework B2 is provided with axle sleeve, is rotated around fixing axle 3 by axle sleeve, and framework A1 is enclosed within outside the axle sleeve, so that framework A1
Can be rotated around framework BA2.
The opposite end of framework A1 and framework B2 laps is provided with the bearing pin 6 through frame side wall, bearing pin 6 be provided with around
The disk roller 9 of its rotation.
As shown in figure 1, mono- side wall of framework A1 is provided with spring catch 8.Spring catch 8 includes alignment pin 11, spring 12, determines
Position set 13, handball 10, as shown in Figure 4 and Figure 5, positioning sleeve 13 is fixed by screws on the wall inner face of framework A1 sides, positioning sleeve
13 tops are provided with centre bore, and alignment pin 11 is arranged in positioning sleeve 13 through the centre bore, and the top of alignment pin 11 passes through
Screw thread is connected with handball 10, side wall of the bottom through framework A1 and framework B2；Handball 10 with diameter greater than the top of positioning sleeve 13
Centre bore, handball 10 is outside positioning sleeve 13；Alignment pin 11 is being close at the wall inner face of framework A1 sides circumferentially arranged with boss, bullet
Spring 12 is arranged in positioning sleeve 13 and is enclosed within alignment pin 11, and the two ends of spring 12 compress the top surface of positioning sleeve 13 and alignment pin respectively
The boss of axle 11；Some pin-and-holes are circumferentially with along fixing axle 3 with the corresponding position of alignment pin 11 on the wall of framework B2 sides, as framework A1
When being relatively rotated with framework B2, alignment pin 11 can coordinate with each pin-and-hole.
As shown in Fig. 2 the end of fixing axle 3 is provided with limited block 5 being close to framework B2 side-walls, limited block 5 and fixing axle 3
It is rigidly connected, the two is relatively fixed, the other end of fixing axle 3 is provided with big nut 4, be arranged on for framework A1 and framework B2 by big nut 4
In fixing axle 3；Limited block 5 is circumferentially with deep-slotted chip breaker, the end of alignment pin 11 with framework B2 side wall pins hole corresponding position along fixing axle 3
Stretch into deep-slotted chip breaker.
When manual pull-up handball 10, when 1 alignment pin leaves 6 bottom plate location hole completely, 5 can be freely adjusted
The relative position of upper holder and 6 lower fixed frames, it is solid on 5 after the relative position of 5 upper holders and 6 lower fixed frames is regulated
The location hole for determining frame and 6 lower fixed frames is concentric, and this unclamps handball, and 1 alignment pin is rebounded automatically in the presence of 2 bearing pin springs,
Fix 5 upper holders and 6 lower fixed frame relative positions.
Under normal condition, the compressing positioning pin axle 11 of spring 12 is, it is necessary to when being clamped to different size wheel, first pull hand
Ball 10, you can the relative position of the framework A1 of quick regulation two and framework B2, when alignment pin 11 and coaxial pin-and-hole, decontrols handball
10, during alignment pin 11 bounces back into pin-and-hole automatically in the presence of spring 12, so as to fix the relative of framework A1 and framework B2
Position, realizes quick regulation and the fixation of two frameworks, so that the different helicopter front-wheel of Rapid matching.
As shown in figure 3, after regulating latter two framework, during aircraft is clamped, disk roller 9 is used for clamping wheel 7, works as roller
When wheel 9 moves closer to wheel, alignment pin 11 is adjusted and blocked to extreme position in the deep-slotted chip breaker of limited block 5, and it is right to be finally completed
The clamping of wheel 7.Disk roller 9 clamps the pusher motivation wheel 7 of wheel 7 and moves, and disk roller 9 is rotated simultaneously with the rolling of wheel 7.
The adjustable wheel holding frame of helicopter tractor of the present invention, by adjusting spring catch, disk roller 9 may be at various
It is different directly various types that rigging position, i.e. helicopter tractor can draw wheel, so that helicopter traction appliance
There is more preferable versatility.
As described above, plan content given in conjunction with the accompanying drawings and embodiments, can derive similar technical scheme.But
Every content without departing from inventive technique scheme, any simply repaiies according to what technical spirit of the invention was made to above example
Change, equivalent variations and modification, still fall within the range of technical solution of the present invention.
