Description

Technical Field

[0001] The invention relates to the technical field of aviation equipment, and in particular to a cleaning rod penetration traction device and a traction method for an aircraft canopy frame. Background Art

[0002] The aircraft canopy is an important part of the aircraft life-saving system. During flight, the canopy glass not only bears the ever-changing external aerodynamic pressure, but also bears the internal load of the cabin. All loads act on the canopy frame cleaning rod. Therefore, whether the cleaning rod can effectively penetrate the canopy frame hole is a key technical requirement for canopy repair. Penetration deviation can easily lead to damage to the canopy glass, metal frame, and polyester ribbon, causing problems such as cabin loss and leakage. In severe cases, it can lead to serious consequences such as cockpit glass explosion, endangering flight and life safety.

[0003] The connection between the canopy cleaning rod and the frame is shown in Figure 1 .

[0004] like Figure 1 As shown in the cross-sectional view, the cockpit cover glass is bonded with a polyester ribbon. When repairing, the cleaning rod needs to be inserted into the polyester ribbon and connected to the cockpit cover glass through the polyester ribbon. Now the aircraft needs to be directly installed by inserting the cleaning rod into the polyester ribbon, applying grease on the cleaning rod, and multiple people cooperate to force it through.

[0005] First, the polyester ribbon is a soft material, and its shape is not fixed when it is placed in the frame. There is a lot of resistance when the cleaning rod is inserted, and it is difficult to insert it directly;

[0006] Secondly, the cleaning rod is made of aluminum alloy, with a length of about 1m and a diameter of about 7.5mm. It has poor deformation resistance and is prone to deformation during penetration, making it difficult to penetrate or deviate.

[0007] The front end of the cleaning rod is conical, and it is easy to damage the metal frame and polyester belt if it is worn off-center. Moreover, this part is invisible and the damage is difficult to find, which poses a safety hazard to the aircraft flight and may cause flight accidents.

[0008] Therefore, a kind of device that can play transition, guiding, traction effect when the canopy cleaning bar penetrates is urgently needed at present, is convenient to the penetration of the canopy cleaning bar. Summary of the invention

[0009] In view of this, the present invention provides a traction device and a traction method for inserting a cleaning rod into a canopy frame of an aircraft.

[0012] The conical head is arranged at one end of the straight rod, and the conical socket is arranged at the other end of the straight rod.

[0013] The conical head is conical, and the center line of the conical head is colinear with the center line of the straight rod.

[0014] A safety wire hole is formed on the surface of the conical head, and the safety wire hole transitions from the middle of the conical head to the straight rod, and a center line of the safety wire hole forms an angle of 30 degrees with a center line of the straight rod.

[0015] The conical socket is located inside the straight rod, and the centerline of the conical socket is colinear with the centerline of the straight rod.

[0016] Furthermore, the total length of the traction device is 1200 mm.

[0017] Further, the conical head is 5 mm long.

[0018] Furthermore, the conical socket is located 5 mm deep inside the straight rod.

[0019] Furthermore, the surface of the conical head is made Fuse hole.

[0020] Another embodiment of the present invention also provides a method for inserting a cleaning rod of an aircraft canopy frame into a traction device. The aircraft canopy frame needs to be installed and inserted into the traction device. When cleaning the rod, the following steps are included:

[0021] First, use a 0.8mm fuse to penetrate the conical head fuse hole of the 3mm traction tool, and then insert both ends of the fuse into the holes of the canopy frame. Use the fuse to pull until the 3mm traction tool is completely inserted into the hole of the canopy frame.

[0022] Push the conical head of the 4mm traction tool into the conical socket of the 3mm traction tool to push out the 3mm traction tool.

[0023] Push the conical head of the 5mm traction tool into the conical socket of the 4mm traction tool to push out the 4mm traction tool.

[0024] Push the conical head of the 6mm traction tool into the conical socket of the 5mm traction tool to push out the 6mm traction tool;

[0025] Push the conical head of the 7mm traction tool into the conical socket of the 6mm traction tool to push out the 6mm traction tool.

[0026] The machine will be used The tip of the cleaning rod is pushed into the conical socket of the 7mm traction tool, and the 7mm traction tool is pushed out. The cleaning rod is inserted into the hole of the cockpit cover frame.
