In figure: 1. pedestal, 2. gusset plate, 3. double-screw bolt, 4. nut, 5. connecting stud, 6. locating slot, 7. via hole, 8. vertical sheet, 9. threaded hole, 10. threaded hole, 11. jacking type aircraft weighting breakout boxs, 12. load transducers, 13. wheel shaft screw jacks, 14. connecting thread holes, 15. push rod cups.
Embodiment
With reference to Figure of description 2, the push rod 15 of wheel shaft screw jack 13 is for being connected with load transducer 12, wherein load transducer 12, and as Fig. 2 top, its basic structure is cylindrical, with screwed hole of centre, referred to here as connecting thread hole 14.
As shown in Figure 2, its upper end has one section of screw thread to the push rod (piston rod) of wheel shaft screw jack 13, also has one section of push rod cup in the upper end of thread segment, is socket cap, and diameter is greater than the large footpath of thread segment.
Under this structural condition, load transducer 12 can be poor with the combination stability of wheel shaft screw jack 13, and the bottom surface of load transducer 12 can not obtain effective support.
A kind of jacking type aircraft weighting breakout box as shown in Figure 1, comprising:
Pedestal 1, for cylinder or frustum cone structure, it in figure, is column structure, main body is solid of revolution, upper bottom surface can support loads sensor 12, form composition surface and supporting surface, and center, the end is provided with the connecting stud 5 for connecting load transducer 12 thereon, avoids coming off of load transducer 12 that unstability causes.
The center of going to the bottom of pedestal 1 has the blind hole for being held into wheel shaft screw jack 13 upper push-rod heads 15, and this blind hole and push rod cup 15 can leave tolerance clearance, with convenient for assembly, also can adopt friction tight mode.
Pedestal 1, for switching basic components, adopts stainless steel part, and processibility is relatively good, also can adopt ironcasting or Al-alloy parts.
For meeting assembled condition stability inferior, this pedestal side is circumferentially all equipped with multiple radial screw bore, and threaded hole 9 and threaded hole 10 is as shown in Figure 1 distributed in the surrounding of pedestal 1, and its assembling acting body now in the following areas.
First aspect is to coordinate gusset plate 2, the parts of the similar unequal angle shown in Fig. 1, it has one and has a plain film, as the horizontal component of gusset plate in figure 2, and then also have one vertical with this plain film and have a vertical sheet 2 of via hole 7, thereby, via hole 7 is for assembling, while coaxially assembling with radial screw bore, plain film is fitted and extends to the lower edge of push rod cup 15 and form the constraint to push rod cup 15 with going to the bottom, plain film by with the coordinating of pedestal 1 bottom surface, and by the constraint of via hole 7, form stable syndeton.
And then, use bolt to connect gusset plate 2, as shown in Figure 1, the assembling of mating with radial screw bore via hole 7 by bolt is via hole 7 in figure and the mating of threaded hole 10.
Said structure relates to the problem of first aspect, can meet stability to a certain extent, relies on plain film part to prop up the lower to realizing constraint of push rod cup 15.
In further selecting, in second aspect, the quantity of radial screw bore is the twice of gusset plate quantity in other words, as shown in Figure 1, thereby, be spaced apart apolegamy for the radial screw bore of assembling gusset plate 2, can be expected that accordingly, gusset plate 2 is uniformly distributed in pedestal surrounding.
So remaining radial screw bore penetrates into described blind hole, thereby is furnished with puller bolt in this remaining radial screw bore, for holding out against in the side of push rod cup 15, formation holds, thereby makes formation between described blind hole and described push rod cup 15 be analogous to the structure of interference fit.
By the synergy of aforementioned two aspects, pedestal 1 can be fixed on push rod cup 15 reliably, unstability is had to better adaptability.
Preferably, the distribution of described radial screw bore on pedestal 1 can adopt Central Symmetry or rotational symmetry configuration, and preferably, the quantity of radial screw bore is six.The threaded hole 10 connecting for gusset plate 2 so has 3, and one of every 120 degree, forms stable three-legged structure.
For simplified structure, described puller bolt is double-screw bolt 3, hexagonal in bolt head part forms, and one-piece construction size is little.
For further simplified structure, be equipped with the counterbore that is formed with vertical sheet 8 shapes of coupling of the radial screw bore of gusset plate, this structure more easily oppose sheet 8 form spacing, thereby can make the stability of structure better.
For the plain film part of gusset plate 2, also can be at the bottom surface structure groove of pedestal 1, thus can form better spacingly, form stable structure.
Preferably, described counterbore is square or rectangle counterbore, more easily forms constraint reliably, the counterbore that the counterbore in figure is semi open model, the shape of coupling gusset plate 2.
Preferably, as shown in Figure 1, described bolt is double-screw bolt 2, coordinates this double-screw bolt, is also provided with nut 4.
As Figure 1-3, breakout box is made up of the pedestal 1 of a stainless steel, three L shaped gusset plates 2, six external thread double-screw bolts, three nuts 4 on the whole.
Installation step (Fig. 1):
1. first wheel shaft screw jack 13 is positioned on the level ground of aircraft weighting relevant position.
2. regulate wheel shaft screw jack 13 to suitable height.
3. the pedestal of breakout box 1 is positioned over to wheel shaft screw jack 13 head ends, namely on the end face of push rod cup 15.
4. with sexangle instrument, three places are not needed to install the double-screw bolt Peripheric locking lifting jack top head end (push rod cup 15) of gusset plate.
5. respectively three L shaped gusset plates 2 are positioned in the groove of pedestal 1, and with remaining three double-screw bolts locking wheel shaft screw jack top head end, have hooked lifting jack head end (push rod cup 15) lower limb so simultaneously.
6. lock respectively three gusset plates 2 with three nuts.
7. last, load transducer, by the double-screw bolt on connector base top, is screwed and is fixed on pedestal.
