Description
Technical Field
The invention relates to the field of installation of pipelines of aircraft equipment, in particular to an anti-interference structure of a pipeline and a rotating shaft.
Background
In order to improve the fighting capacity of modern fighter planes, electronic products are usually arranged in some rotating parts, the electronic products move along with the rotating parts, the rotating parts usually rotate around a certain shaft, cables/pipes connected with the electronic products also rotate around the shaft, and therefore the cables/pipes are usually flexible cables/pipes capable of being bent back and forth. For some places with narrow space of the airplane, because the flexible cable/pipeline has no regular deformation when rotating around the shaft, if the clearance between the flexible cable/pipeline and the rotating shaft is small, the cable/pipeline is easy to interfere with the structure/mechanism in the moving process, and the cable/pipeline is easy to wear. According to the design requirements of the airplane, a certain gap must be kept between the motion envelope of the moving part and other objects on the periphery, and interference can not occur, so that the motion path of the flexible cable/pipeline needs to be restrained, and interference between the cable/pipeline and the rotating shaft in the motion process is prevented.
The invention provides an installation scheme of a flexible cable/pipeline over-movement rotating shaft, which can restrict the deformation path of the cable/pipeline and ensure that the cable/pipeline does not interfere with the rotating shaft in the movement process.
Disclosure of Invention
The purpose of the invention is as follows: the installation scheme of the over-movement rotating shaft of the flexible cable/pipeline is provided, the installation scheme can ensure that the cable/pipeline does not interfere with the rotating shaft in the movement process, and the problem of abrasion of the cable/pipeline is solved.
The technical scheme of the invention is as follows:
the anti-interference structure for the pipeline and the rotating shaft comprises a rotating part 1, the rotating shaft 2, a fixing part 3, a flexible cable/pipeline 4, first equipment 5, a baffle 6, a clamp 7 and second equipment 8;
the rotating part is rotatably connected with the fixed part through a rotating shaft, the rotating part 1 is a movable part and can rotate around the rotating shaft 2, the first equipment 5 is installed inside the rotating part 1, and the first equipment 5 and the rotating part 1 rotate integrally; the baffle 6 is fixed on the rotating part, the baffle forms an isolation cover, the baffle is isolated between the flexible cable or pipeline 4 and the rotating shaft, an opening 9 is formed in the isolation cover, the opening corresponds to the opening of the rotating part, the first equipment 5 is arranged in the opening of the rotating part, and the flexible cable or pipeline 4 penetrates through the opening of the isolation cover and the opening of the rotating part to be connected with the first equipment;
a clamp 7 is arranged on the baffle 6 and used for limiting the movement range of the flexible cable or the pipeline, so that the flexible cable or the pipeline cannot leave the area covered by the isolation cover.
Further, the baffle 6 is mounted on the rotating part through a fixing bracket.
Further, the clamp 7 fixes the flexible cable/pipe 4 on the baffle 6, so that the cable/pipe fixed by the clamp 7 has no relative movement with the baffle 6 during the rotation of the rotating part, thereby preventing the cable/pipe and the baffle 6 from being worn.
Furthermore, the flexible cable/pipeline can be bent or twisted in the rotating process, the clamp 7 fixes the flexible cable/pipeline 4 on the baffle 6, and a certain margin is reserved between the clamp 7 and the first device 5 for compensation in the rotating process.
The invention has the beneficial effects that: (1) the deformation path of the flexible cable/pipeline passing through the rotating shaft in the rotating process can be restrained; (2) the gap between the flexible cable/pipeline and the rotating shaft in the rotating process can be ensured; (3) the flexible cable/pipe is only subjected to bending movement, reducing the wear caused by back-and-forth friction between the flexible cable/pipe and the structure.
