Description

Technical Field

[0001] The present invention relates to the field of helicopter support equipment, and in particular to a disassembly and assembly device suitable for an airborne dipping sonar and a working method thereof. Background Art

[0002] Dipping sonars are core equipment for helicopters performing underwater target detection, positioning, and anti-submarine warfare missions. Their ability to be quickly disassembled and assembled directly impacts mission response efficiency and equipment maintenance reliability. As performance requirements for dipping sonars continue to rise, they are also growing larger and heavier. Even the latest models require more than two or three people to lift. Aircraft space is limited, and lifting them through the helicopter's speaker opening into the cabin is difficult. If urgent replacement or repair of a dipping sonar is required, manual disassembly is inefficient, unsafe, and prone to damage, making it difficult to meet the demands of helicopter dipping sonar systems.

[0003] However, in the existing technology, the disassembly and assembly of the dipping sonar relies on the collaboration of multiple people. The dipping sonar is moved in and out of the cabin by pulling and tugging. Manual handling is prone to mechanical damage and manual disassembly and assembly rely on experience and judgment. There is a lack of standardized positioning and lifting devices, which leads to problems such as insufficient positioning accuracy of the dipping sonar and unstable lifting process that can easily damage the sonar. In addition, the staff need to work inside the narrow space of the cabin. The limited cabin space leads to too long installation and disassembly time, which cannot meet the needs of handling emergency tasks. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes a disassembly and assembly device suitable for airborne dipping sonar and a working method thereof, so as to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To this end, the specific technical solutions adopted in the present invention are as follows:

The vertical reinforcement support rod outside the cabin is connected with a buffer block to prevent the dipping sonar from being damaged by collision during transportation. Several triangular support frames are respectively connected between the first support rod outside the cabin and the second support rod outside the cabin, and between the third support rod outside the cabin and the fourth support rod outside the cabin. Limit blocks are connected to the first support rod outside the cabin and the fourth support rod outside the cabin to limit the descending distance of the dipping sonar and prevent the dipping sonar from colliding with the support plate and damaging the dipping sonar.

[0014] Furthermore, the fixing assembly includes a second support frame and an outer limit plate. The outer limit plate is connected to the top of the second support frame. The outer limit plate has fixing holes on both sides below. When stored, the fixing holes are connected to the inner fixing rods of the inner disassembly and assembly device, fixing the inner disassembly and assembly device. The hanging sonar clamp is placed in the V-shaped structure of the inner disassembly and assembly device to form an assembly.
