Description

Technical Field

[0001] The utility model relates to the technical field of aviation cables, and in particular to a device for in-situ detection of aviation cables. Background Art

[0002] Aviation cables are used for signal transmission and power transmission inside aircraft. They are mainly divided into four categories: control cables, signal transmission cables, power cables and special cables. Due to the specific working environment of aviation work, the requirements for aviation cables are getting higher and higher. Therefore, in order to prevent bulging when using aviation cables, they need to be inspected and processed to ensure their safe use.

[0003] When detecting bulges on existing aviation cables, only two sides of the cable can be inspected, but bulges will appear all around the cable. This method will lead to incomplete inspection, thereby reducing the inspection quality and work efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a device for in-situ detection of aviation cables to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

The detection device body includes a bearing base plate, a detection frame is fixedly installed on the top right side of the bearing base plate, and a support vertical plate is fixedly installed on the rear end of the top left side of the bearing base plate.

[0007] A detection unit is arranged inside the detection frame, and a winding unit is arranged at the front end of the supporting vertical plate.

[0008] A further improvement of the technical solution of the utility model lies in that: the detection unit includes detection blocks arranged on the four sides of the interior of the detection frame, a detection hole is opened in the middle position of the detection block, sleeves are fixedly installed at the four corners of the interior of the detection frame, a piston rod is movably inserted inside the sleeve, a fixed block is fixedly installed on the other end of the piston rod, the inner side of the fixed block is welded to the outer surface of the detection block, four groups of detection blocks are arranged, which are completely fitted on the outer surface of the linear body, so that the detection is more comprehensive.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1-5As shown, the utility model provides a device for in-situ detection of aviation cables, including a detection device body 1, which is suitable for use in aviation cable detection. The detection device body 1 includes a bearing base plate 2, a detection frame 3 is fixedly installed on the top right side of the bearing base plate 2, a support vertical plate 4 is fixedly installed on the top left rear end of the bearing base plate 2, a detection unit is arranged inside the detection frame 3, and a winding unit is arranged at the front end of the support vertical plate 4. The detection unit includes a detection block 31 arranged on the inner periphery of the detection frame 3, a detection hole 32 is opened in the middle position of the detection block 31, sleeves 33 are fixedly installed at the inner periphery corners of the detection frame 3, and the inner movable plug of the sleeve 33 There is a piston rod 34, and a fixed block 35 is fixedly installed on the other end of the piston rod 34. The inner side of the fixed block 35 is welded to the outer surface of the detection block 31. The bottom end of the piston rod 34 is located inside the sleeve 33 and a moving plate 36 is fixedly installed. Limiting slide bars 37 are movably inserted on all sides of the moving plate 36. The outer surface of the limiting slide bar 37 is located below the moving plate 36 and is movably sleeved with a return spring 38. An extrusion spring 310 is fixedly installed on the bottom end of the moving plate 36, and an extrusion sensor 39 is fixedly installed on the other end of the extrusion spring 310. The extrusion sensor 39 is fixedly installed on the inner bottom end of the sleeve 33, and the extrusion sensor 39 is connected to the external receiver signal.

[0027] Furthermore, during the winding process, the cable continuously moves inside the detection hole 32. When a bulge appears on the wire, the bulge will squeeze the detection block 31. At this time, the movement of the detection block 31 causes the piston rod 34 to shrink inside the sleeve 33, thereby causing the moving plate 36 to move down and slide on the outer surface of the limiting slide bar 37. At this time, the reset spring 38 and the extrusion spring 310 are both in a contracted state. When the extrusion spring 310 shrinks, the extrusion sensor 39 receives a signal and transmits it to a receiver (not shown in the figure), thereby facilitating the processing of the bulging wire. When the wire continues to move forward, the limiting plate 21 is located at the front end of the detection frame 3 to prevent the pulling caused by the winding of the wire from affecting the bulge detection.

[0028] Example 2

[0029] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the winding unit includes a limit plate 21 fixedly installed in the middle position of the top of the bearing bottom plate 2, a rotating disk 41 is rotatably installed inside the supporting vertical plate 4, a winding roller 42 is fixedly installed on the front side of the rotating disk 41, a locking groove 43 is opened on the outer surface of the rotating disk 41, a locking convex strip 44 is fixedly installed on the inner wall of the groove of the supporting vertical plate 4, a driven gear 45 is fixedly installed on the rear side of the rotating disk 41, a driving gear 46 is meshed and connected on the left side of the driven gear 45, and a rotating handle 47 is fixedly installed on the middle position of the driving gear 46.

[0030] Furthermore, the aviation cable to be tested is inserted into the detection hole 32 and the limit plate 21, and then wound on the outer surface of the winding roller 42. At this time, the driving gear 46 is driven by rotating the handle 47 to cause the driven gear 45 to rotate, so that the winding roller drives the cable to be wound up.

[0031] The following is a detailed description of the working principle of the device for in-situ detection of aviation cables.

[0032] like Figure 1-5 As shown, when in use, the aviation cable to be detected is inserted into the detection hole 32 and the limit plate 21, and then wound on the outer surface of the winding roller 42. At this time, the driving gear 46 is driven by rotating the handle 47 to cause the driven gear 45 to rotate, so that the winding roller drives the cable to be wound. During the winding process, the cable continuously moves inside the detection hole 32. When the line body bulges, the bulge will squeeze the detection block 31. At this time, the movement of the detection block 31 causes the piston rod 34 to shrink inside the sleeve 33, so that the moving plate 36 moves down and slides on the outer surface of the limit slide bar 37. At this time, the reset spring 38 and the extrusion spring 310 are both in a contracted state. When the extrusion spring 310 shrinks, the extrusion sensor 39 receives the signal and transmits it to the receiver (not shown in the figure), so as to facilitate the processing of the bulging line body. When the line body continues to move forward, the limit plate 21 is located at the front end of the detection frame 3 to prevent the pulling caused by the winding of the line body from affecting the bulge detection.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
