Description

Technical Field

[0001] This application belongs to the technical field of cross - pipe fixing design, and particularly relates to a clamp structure for fixing cross - pipes. Background Art

[0002] Aerospace engines use clamp structures to achieve the connection and fixation between pipelines. There are usually two spatial structures between pipelines: parallel and cross - shaped. Parallel pipelines can be fixed using double - link clamps, while cross - shaped pipelines usually cannot be directly fixed with a single structure.

[0003] Currently, in most cases, two single - link clamps are used back - to - back at a 90 - degree angle to fix one pipeline each, so as to fix the cross - shaped pipeline. Bolts and nuts are used to connect the two single - link clamps. In order to ensure the distance between pipelines, a spacer sleeve also needs to be set between the two single - link clamps. As Figure 1 shown, this technical solution has the following defects:

[0004] 1) Both of the two single - link clamps are cantilever structures. During transportation and testing, they are prone to deformation under external forces.

[0005] 2) During installation, the angle between the two single - link clamps needs to be manually ensured, resulting in poor installation and maintainability.

[0006] 3) There are many types and quantities of parts, which are not convenient for management during the parts collection and assembly stages.

[0007] In view of the existence of the above - mentioned technical defects, this application is proposed. Summary of the Invention

[0008] The purpose of this application is to provide a clamp structure for fixing cross - pipes, so as to overcome or mitigate at least one aspect of the known technical defects.

[0009] The technical solution of this application is as follows:

[0011] The semi - clamp for X - direction fixation is semi - circular in shape, and there are two, which are arranged oppositely and used to clamp the pipeline in the X - direction.

[0012] The roots of the two semi - clamps for X - direction fixation successively have a first positioning block, a second positioning block, and a third positioning block. The second positioning block protrudes outward from the first positioning block and the third positioning block, and the two second positioning blocks form a central hole.

[0013] The semi-clamps for fixing in the Y direction are semi-circular in shape, and there are two of them, which are arranged oppositely to clamp the pipeline in the Y direction. Among them, the X direction and the Y direction are perpendicular to each other, and the pipelines in the X direction and the Y direction are cross pipelines.

[0014] The roots of the two semi-clamps for fixing in the Y direction sequentially have a first positioning groove, a second positioning groove, and a third positioning groove. Among them, the two first positioning grooves, the second positioning groove, and the third positioning groove are clamped on the outer sides of the first positioning block, the second positioning block, and the third positioning block along the X direction from both ends, clamping the two semi-clamps for fixing in the X direction, and there are installation holes at the bottoms of the two second positioning grooves.

[0015] The fastening bolt is arranged through the two installation holes and its central hole.

[0016] The fastening nut is threadedly connected to the fastening bolt and cooperates with the fastening bolt to fasten the two semi-clamps for fixing in the Y direction along the X direction.

[0017] According to at least one embodiment of the present application, in the above-mentioned clamp structure for fixing the cross pipeline, the two first positioning blocks are trapezoidal in shape and are inclined at both ends along the X direction.

[0018] The bottoms of the two first positioning grooves are trapezoidal in shape and are in mating contact with the inclined surfaces between the two ends of the two first positioning blocks.

[0019] According to at least one embodiment of the present application, in the above-mentioned clamp structure for fixing the cross pipeline, the two third positioning blocks are trapezoidal in shape and are inclined at both ends along the X direction.

[0020] The bottoms of the two third positioning grooves are trapezoidal in shape and are in mating contact with the inclined surfaces between the two ends of the two first positioning blocks.

[0021] According to at least one embodiment of the present application, in the above-mentioned clamp structure for fixing the cross pipeline, the two second positioning blocks are semi-circular in shape;

[0022] The two third positioning grooves are circular in shape and envelop the outer sides of the two second positioning blocks from both ends.

[0023] According to at least one embodiment of the present application, in the above-mentioned clamp structure for fixing the cross pipeline, the fastening nut uses a self-locking nut.

[0024] The present application has at least the following beneficial technical effects:

[0025] A clamp structure for fixing a cross pipeline is provided to fix the cross pipeline. The cantilever structure design is cancelled, and it has strong rigidity in all directions. It is not easily deformed by external forces after installation. Moreover, during installation, the angle is determined by the inherent structure and does not require manual guarantee, and the installation and maintenance are good. In addition, the physical state is a single component with fewer parts, which can reduce the steps and manpower in the parts collection and assembly stages and is convenient for management.

[0042] The roots of the two semi-clamps 1 for fixing in the X direction successively have a first positioning block 11, a second positioning block 12, and a third positioning block 13. The second positioning block 12 protrudes outward from the first positioning block 11 and the third positioning block 13, and the two second positioning blocks 12 form a central hole, as Figure 4 shown.

[0043] The two first positioning blocks 11 and the third positioning block 13 can be designed in a trapezoidal shape, inclined at both ends in the X direction, and the second positioning block 12 can be designed in a semi-circular shape.
