Description

Technical Field

[0001] This application belongs to the technical field of aircraft multi-pipeline support structure design, specifically to an aircraft multi-pipeline large span Background Art

[0002] Pipes are everywhere on the aircraft, used to transmit gases and liquids such as air, fuel, and hydraulics, and are an important part of the aircraft.

[0003] In order to enhance the rigidity of pipelines on aircraft, the pipelines are often fixed to the aircraft structure along the way through fixing structures such as brackets and clamps.

[0004] Currently, the fixed support structures for aircraft pipelines are mostly composed of scattered small parts, which provide fixed support for individual pipelines along the way. This makes disassembly and assembly inconvenient. In addition, some locations on the aircraft have limited space and complex internal structures, such as the interior of the tail, making it even more difficult to use scattered small parts to fix and support the pipelines along the way. Therefore, the fixed support positions for the pipelines are usually reduced. This practice will reduce the degree of reinforcement of the pipeline stiffness, which may cause deformation of the spatial pipeline stiffness due to the movement of the control surface.

[0005] This application is proposed in view of the above-mentioned technical defects. Utility Model Content

[0027] A multi-pipeline large-span detachable bracket for aircraft, such as Figure 1 As shown, it includes a fixing plate 1, a supporting plate 2, and a mounting clamp 3.

[0028] Multiple fixing plates 1 are arranged in a circular pattern, with gaps between adjacent fixing plates 1. Each fixing plate 1 has mounting edges at both ends, which are bolted to the aircraft structure, which can be a load-bearing structure such as a beam, frame, or box segment. Each fixing plate 1 can be designed to have an arcuate shape to enhance torsional resistance, and the mounting edge at one end can be designed to be an inward-facing flange, while the mounting edge at the other end can be an outward-facing flange.

[0029] There are multiple support plates 2, and one side edge of each support plate 2 is connected to the inner side of a fixed plate 1; the other side edges of each support plate 2 are connected to each other, and the overall shape can be cross-distributed or cross-shaped to enhance the overall rigidity of the structure.

[0030] There are multiple groups of mounting clamps 3. One or more groups of mounting clamps 3 can be distributed on one support plate 2, and mounting clamps 3 can be distributed on both side walls of each support plate 2. The support plate 2 and the mounting clamps 3 are welded together.

[0031] Each group of mounting clamps 3 is distributed along the axial direction of the support plate 2 to fix the pipeline along the way.

[0032] The aircraft multi-pipe large-span detachable bracket disclosed in the above embodiment can, in specific applications, first clamp the corresponding pipelines along the way through each set of mounting clamps 3, and then connect the mounting edges at both ends of each fixing plate 1 to the aircraft structure with bolts for fixed support. The fixed positions of each fixing plate 1 on the aircraft structure are concentrated, which is convenient for overall disassembly and assembly. It is easy to apply in situations where space is limited and the internal structure is complex. In addition, through the design of multiple support plates 2 and multiple sets of mounting clamps 3, fixed support for multiple pipelines at the same position can be achieved, and the distribution position of the mounting clamps 3 can be designed according to the need to enhance the rigidity of the pipeline. It is not restricted by the limited space and complex structure on the aircraft, and can ensure the enhancement effect of pipeline rigidity within a large span.

[0036] The shapes of the mounting edges at both ends of the fixing plate 1 and the number and position distribution of the bolt holes thereon are determined according to the requirements of the connection strength and the limitations of the aircraft structure.
