Description

TECHNICAL FIELD

[0001] The present application relates to an aircraft jacking system, in particular to an aircraft jacking air bag and a manufacturing method thereof. BACKGROUND

[0002] In the prior art, the aircraft jacking rescue device includes a hydraulic rescue jack and a hoisting device.

[0003] The hydraulic rescue jack is safe and reliable, and is suitable for vertical jacking, but the initial height is too high, and only the pre-jacking point of the aircraft can be jacked, and the lateral displacement of the jacking point of the aircraft due to the change of the attitude during the jacking process cannot be compensated.

[0004] The hoisting device has a low initial rescue height, can jack any jacking position of the aircraft body, and can compensate the lateral displacement of the jacking point of the aircraft due to the change of the attitude during the jacking process, but only a limited part of the aircraft body can be jacked, and a heavy crane must be provided during use, which is not convenient in actual use. SUMMARY

[0005] In view of the deficiencies in the prior art, the present application provides an aircraft jacking air bag and a manufacturing method thereof, which can avoid secondary damage to the aircraft body during rescue, has strong practicability, is convenient to operate, saves time and effort, and greatly improves work efficiency.

[0006] The technical scheme for achieving the present application is as follows:

[0007] An aircraft jacking air bag, which is different from the prior art, comprises an air bag body, wherein the air bag body is composed of an air bag corner, an air bag edge, an air bag handle and an inflation valve, two arc-shaped edges of the air bag corner are overlapped with each other, the straight edge of the air bag corner is overlapped with the long edge of the air bag edge, a tape is attached to the inside and outside of the overlapping part to fix the tape, the inflation valve is fixedly installed, and the air bag handle is fixedly attached to the air bag through an air bag handle base.

[0008] The inflation valve is a POM valve with a diameter of 63 mm, a height of 51 mm and a pressure of 15 psi.

[0009] The air bag handle is a high-altitude safety rope with a diameter of 16 mm.

[0010] The manufacturing method of the aircraft jacking air bag comprises the following steps:

[0011] (1) The straight edge of the air bag corner piece is overlapped on the second long edge of the air bag edge piece, and after the adhesive is dried, 3 sewing lines are sewn, and a total of 8 sewing lines are sewn;

[0012] (2) Lap the arc edges of the airbag corner pieces on two adjacent sides. After the adhesive dries, sew 3 sewing threads to complete one corner of the airbag. Repeat this step to lap and sew in sequence to complete the other three corners of the airbag; paste and fix the patch strips and pure rubber strips inside and outside the lap joints;

[0013] (3) Lap the first long sides of the airbag side pieces on two adjacent sides. After the adhesive dries, sew 3 sewing lines. Repeat this step to lap and sew in sequence to complete the lap joints of the other two sides of the airbag, leaving one side un-lapped; paste and fix the patch strips and pure rubber strips inside and outside the lap joints, and fix the inflation valve at the corresponding position at the same time;

[0014] (4) Lap the two short sides of the adjacent airbag side pieces with each other. After the adhesive dries, sew 3 sewing lines, and paste and fix the patch strips and pure rubber strips inside the lap joint;

[0015] (5) Paste a patch strip on the inner side of the airbag side that is not lapped in step (3) to make the overall airbag form a "hui" - shaped structure. After forming, paste and fix the patch strips and pure rubber strips at each sewing line;

[0016] (6) Paste and fix the patch strips and pure rubber strips at the inner lap joint of the "hui" - shaped airbag;

[0017] (7) Bond the two ends of the airbag handle to the airbag handle base. The middle of the airbag handle passes through the middle through - hole of another airbag handle base and is fixed to the airbag handle base with a patch strip. The airbag handle base is fixedly pasted on the airbag.

[0018] The width of the patch strip is 5 - 8 cm; the width of the pure rubber strip is 8 - 14 cm.

[0019] During the forming process, the lap width of all patch strips is 40 mm ± 2 mm.

[0020] The jacking airbag manufactured by the present invention is applicable to aircraft of different models, enabling rescue personnel and maintenance personnel to better carry out rescue and maintenance work. The greatest function of this aircraft jacking airbag is to ensure the avoidance of secondary damage to the aircraft body during rescue, with strong practicability, convenient operation, time - saving and labor - saving, and greatly improving work efficiency.

[0030] The content of the present application is further explained below by examples and drawings, but is not limited to the present application. EXAMPLE

[0031] An aircraft jacking airbag is composed of airbag corners, airbag sides, tapes, airbag handle bases, airbag handles, inflation valves, etc., wherein:

[0032] 1) The straight edges of the airbag corner pieces 1 are lap jointed on the second long edges of the airbag side pieces 2, and after the adhesive is dried, 3 lines of sewing thread are sewn, and a total of 8 lines are sewn;

[0033] 2) The arc edges of two of the airbag corner pieces 1 are lap jointed, and after the adhesive is dried, 3 lines of sewing thread are sewn, and one of the corners of the airbag is completed. The remaining three corners are lap jointed and sewn in the same way. 8 cm wide main cloth tapes 3 are first pasted inside and outside the lap joint, and then 14 cm wide pure glue strips are pasted;

[0034] 3) The first long edges of two of the airbag side pieces 2 are lap jointed, and after the adhesive is dried, 3 lines of sewing thread are sewn. The lap joints on the remaining two edges are lap jointed and sewn in the same way, and the lap joint on the remaining edge is not operated. 5 cm wide main cloth tapes 3 are first pasted inside and outside the lap joint, and then 8 cm wide pure glue strips are pasted, and the inflation valve 6 is fixed at the corresponding position;
