Description

Technical Field

[0001] The present application relates to the field of cable production, and in particular to a device for detecting damage to a wire casing. Background Art

[0002] After the cable is coated with the insulation layer, a leakage test is usually required. By applying a high voltage, the cable is tested for insulation defects or leakage problems. This test helps to find defects that may cause current leakage, such as holes, cracks or other damage, to ensure that the cable can safely and reliably transmit power, signals or data in actual operation, while preventing safety hazards caused by leakage. Leakage testing is an important quality control measure that helps improve the reliability and stability of cables.

[0003] The existing testing method usually uses an industrial frequency spark machine to test the cable coated with insulation. A high voltage is applied to the cable. If the cable insulation is good, the current will flow in the insulation layer of the cable. If the insulation of the power line is damaged or defective, the high voltage will cause arc discharge, i.e. spark discharge, at the damaged place to achieve the test of the cable.

[0004] However, in the process of testing the cable with the existing power frequency spark machine, when the cable is transmitted from the entrance to the exit of the power frequency spark machine, the wire in the detection area of ​​the power frequency spark machine is in an unrestrained state, so that the wire is in a shaking state when passing through the conductor of the power frequency spark machine, resulting in a detection blind area in the process of the conductor detecting the cable, thereby reducing the detection result, and further improvement is needed. Utility Model Content

[0005] In order to reduce shaking during wire detection, the present application provides a wire casing damage detection device.

[0006] The present application provides a wire housing damage detection device that adopts the following technical solution:

[0007] A wire casing damage detection device comprises a box, a limit assembly and an adjustment assembly, wherein the box is used to install the detection assembly, and the box is provided with through holes at both ends along its length direction, and the through holes are used for cables to pass through the box, and the limit assembly and the adjustment assembly are arranged on the box at the through holes, and the limit assembly comprises a positioning roller and an adjustment roller, and the positioning roller and the adjustment roller are rotatably carried on the box at the through holes, and the adjustment assembly is used to adjust the adjustment roller to be close to or away from the positioning roller.

[0008] By adopting the above technical scheme, the cable moving out along the through-hole is limited by the positioning roller and the adjusting roller, so that the cable can only pass between the positioning roller and the adjusting roller. When the detection component detects the cable, the moving paths of the two ends of the cable in the box are limited by the adjusting roller and the positioning roller, thereby reducing the swing of the cable during the cable detection process of the detection component, which plays a positive guiding role in improving the accuracy of the cable detection result of the detection component; at the same time, the spacing between the adjusting roller and the positioning roller can be adjusted by the adjusting component to meet the limiting requirements of cables with different wire diameters, which is highly practical. When the cable to be detected reaches the detection component in the box along the through-hole, the detection component starts to detect the cable, which reduces the shaking of the wire during the detection process to a certain extent.

[0009] Preferably, the adjustment assembly includes a sliding plate and an adjusting screw, the adjusting roller is carried on the sliding plate and rotates in a vertical direction, the sliding plate is slidably arranged on the box body, the adjusting screw is movably arranged on the box body, and the adjusting screw is fixedly connected to the sliding plate; when the adjusting screw rotates along the box body, the sliding plate carries the adjusting roller to move closer to or away from the positioning roller.

[0010] By adopting the above technical scheme, the sliding plate can carry the adjusting roller to slide along the box body, so that the adjustment of the distance between the adjusting roller and the positioning roller can be relatively smooth. At the same time, because the adjusting screw is fixedly connected to the sliding plate, when the adjusting screw is rotated clockwise or counterclockwise, the adjusting roller on the sliding plate synchronously follows the adjusting screw to approach or move away from the positioning roller along the box body, and the adjustment mechanical structure is simple and highly practical.

[0011] Preferably, it also includes a transmission assembly, which includes a transmission shaft, a first bevel gear and a second bevel gear, the transmission shaft is rotatably supported on the box body, the first bevel gear is coaxially fixed with the transmission shaft, the second bevel gear is coaxially fixed with the positioning roller, and the second bevel gear is meshed with the third bevel gear.

[0012] By adopting the above technical solution, the transmission shaft can be externally connected to a driving member, and the driving member drives the transmission shaft to rotate, so that the first bevel gear coaxially fixed with the transmission shaft drives the second bevel gear meshing with it to rotate, thereby rotating the positioning roller coaxially fixed with the second bevel gear, and when the cable passes between the positioning roller and the adjusting roller, the positioning roller is in a rotating state, providing power for the cable to pass through the through hole, thereby reducing the resistance encountered by the cable when passing between the positioning roller and the adjusting roller, so that the cable can be smoothly discharged between the adjusting roller and the positioning roller.

[0013] Preferably, the transmission assembly also includes a third bevel gear and a fourth bevel gear, the fourth bevel gear is coaxially fixed with the adjusting roller, the third bevel gear is meshed with the fourth bevel gear, the third bevel gear is keyed to the transmission shaft, and the third bevel gear is transitionally matched with the transmission shaft.

[0014] By adopting the above technical solution, the first bevel gear and the third bevel gear are in a coaxial fixed state with the transmission shaft. Therefore, when the transmission shaft rotates, the first bevel gear and the third bevel gear rotate synchronously with the transmission shaft, thereby driving the second bevel gear and the fourth bevel gear to rotate synchronously, so that the second bevel gear and the fourth bevel gear rotate synchronously, further reducing the resistance encountered by the cable when passing between the positioning roller and the adjusting roller. At the same time, because the third bevel gear and the transmission shaft pin key cooperate, and the third bevel gear and the transmission shaft transition cooperate, it is convenient to adjust the spacing between the first bevel gear and the third bevel gear.

[0015] Preferably, a sliding seat is provided on the transmission shaft, the third bevel gear is rotationally connected to the sliding seat, and the sliding seat is fixedly connected to the sliding plate.

[0016] By adopting the above technical solution, since the sliding seat is fixedly connected to the sliding plate, when the sliding plate is adjusted, the sliding seat moves synchronously with the sliding plate. Since the sliding seat is rotationally connected to the third bevel gear, the spacing between the positioning roller and the adjusting roller can be adjusted by adjusting the sliding plate, and the spacing between the first bevel gear and the third bevel gear can be synchronously adjusted. The operation is simple and the stability is high.

[0017] Preferably, the limiting assembly further comprises a transverse auxiliary roller, and the auxiliary roller is rotatably carried on the box body at the penetration hole in a horizontal direction.

[0018] By adopting the above technical solution, the cable removed along the through-hole is supported by the transverse auxiliary roller. At the same time, because the transverse auxiliary roller is rotatably supported on the box body, the friction force encountered by the cable during the transverse transportation along the through-hole is reduced by the transverse auxiliary roller, so that the cable can slide smoothly along the space formed by the transverse auxiliary roller, the positioning roller and the adjustment roller.

[0019] Preferably, an adjustment seat is provided on the box body at the through hole, and the adjustment seat is provided with an adjustment groove along its vertical direction, and the transverse auxiliary roller can be adjusted upward or downward along the adjustment groove.

[0020] By adopting the above technical solution, the height of the lateral auxiliary roller in the vertical direction is adjusted through the adjustment groove to meet the cable supporting requirements of different wire diameters.

[0021] Preferably, the box body comprises an upper shell and a lower shell, the upper shell is hinged to the lower shell, an electromagnetic attractor is provided on one end of the lower shell away from the hinge between the upper shell and the lower shell, and the electromagnetic attractor is electrically connected to the detection component.

[0022] By adopting the above technical solution, since the inside of the box is in a high voltage state when the detection component is detecting the cable, the electromagnetic attractor is electrically connected to the detection component. When the detection component is detecting the cable, the electromagnetic attractor is always energized, tightly attracting the upper shell and the lower shell. At this time, the operator cannot open the upper shell along the lower shell, reducing the probability of the operator accidentally touching and getting an electric shock, which plays a positive guiding role in improving overall safety.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The cable is limited by the positioning roller and the adjusting roller so that it can only pass between the two. This design effectively reduces the shaking of the cable during the detection process and improves the accuracy of the detection. The adjustment component allows the spacing to be adjusted according to the cables of different wire diameters, which improves practicality;

[0025] 2. The sliding seat is fixedly connected to the sliding plate. By adjusting the sliding plate, the spacing between the positioning roller and the regulating roller can be adjusted at the same time, so that the distance between the first bevel gear and the third bevel gear can be adjusted synchronously. This design is simple and easy to operate with high stability;

[0026] 3. The electromagnetic attractor is electrically connected to the detection component to ensure that the upper and lower shells are always in the attracted state during cable detection to prevent accidental opening, reduce the risk of electric shock, and improve equipment safety.

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a wire housing damage detection device. Figure 1 and Figure 2 A wire housing damage detection device includes a box body 1, a limit assembly 2 and an adjustment assembly 3. The box body 1 is provided with through holes 4 at both ends along its length direction. The through holes 4 are used for cables to pass through. The limit assembly 2 includes a positioning roller 21 and an adjustment roller 22. The positioning roller 21 and the adjustment roller 22 are rotatably carried on the box body 1 at the through holes 4. The adjustment assembly 3 is used to adjust the adjustment roller 22 to be close to or away from the positioning roller 21. The box body 1 is used to install the detection assembly.

[0032] Furthermore, the box body 1 includes an upper shell 11 and a lower shell 12, the upper shell 11 is hinged to the lower shell 12, and two through holes 4 are provided, and the two through holes 4 are respectively opened at both ends of the lower shell 12 along its length direction. At the same time, a supporting tray 121 is installed along the length direction of the lower shell 12, and the outer contour of the supporting tray 121 is set in an arc shape. The cable can be inserted through one of the through holes 4 and pass through the supporting tray 121 and out from the other through hole 4.

[0033] Among them, the detection component is installed in the upper shell 11 and the lower shell 12. The detection component is composed of components such as a discharge electrode, a control unit, a high-voltage generator and a detection circuit. It is a component of a conventional industrial frequency spark machine. Each of them works together to detect whether the cable casing is damaged. It is a prior art. Its working principle and installation method in the upper shell 11 and the lower shell 12 are not described in detail here.

[0034] Meanwhile, in the present embodiment, two groups of the limit assembly 2 and the adjustment assembly 3 are respectively provided, and are respectively installed on the lower shell 12 at the two penetration holes 4 .

[0035] Therefore, the distance between the adjusting roller 22 and the positioning roller 21 is adjusted by adjusting the component 3, so as to limit the cable passing through the through hole 4, so that the two ends of the cable between the two through holes 4 are in a restrained state, thereby reducing the swing of the cable when the cable passes along the detection component, and playing a positive guiding role in improving the detection result of the detection component.

[0036] Reference Figure 1 An electromagnetic attractor 13 is provided on one end of the lower shell 12 which is away from the upper shell 11 and hinged with the lower shell 12 , and the electromagnetic attractor 13 is electrically connected to the detection component.

[0037] Specifically, the electromagnetic attractor 13 is composed of an electromagnetic coil, an attracting iron core and a control circuit. When current passes through the electromagnetic coil, the magnetic field generated makes the attracting iron core magnetic and adsorbed on the upper shell 11, thereby achieving a firm connection between the upper shell 11 and the lower shell 12. The control circuit is used to adjust the current and control the working state of the attractor. The electromagnetic attractor 13 uses this principle to achieve tight adsorption of parts when powered on, thereby improving the safety and stability of the equipment. It is a prior art and its working principle will not be described in detail here.

[0038] Correspondingly, when the detection component is detecting the cable, the electromagnetic attractor 13 is always in a powered state. During this process, the upper shell 11 and the lower shell 12 are always attracted to each other through the electromagnetic attractor 13. Therefore, when the detection component is working normally, the operator cannot open the upper shell 11, which plays a positive guiding role in reducing the probability of the operator accidentally opening the upper shell 11 and causing electric shock.

[0039] It should be noted that since there are two groups of limit components 2, adjustment components 3 and through holes 4, and each group has the same components and installation method, the following content takes one group to describe its installation method and components in detail.

[0040] Reference Figure 2 The adjusting assembly 3 includes a sliding plate 31 and an adjusting screw 32. The adjusting roller 22 is carried on the sliding plate 31 and rotates in the vertical direction. The sliding plate 31 is slidably set on the box body 1. The adjusting screw 32 is movably set on the box body 1. The adjusting screw 32 is fixedly connected to the sliding plate 31. When the adjusting screw 32 rotates along the box body 1, the sliding plate 31 carries the adjusting roller 22 to move closer to or away from the positioning roller 21.

[0041] Specifically, a mounting seat 7 is installed on the lower shell 12 at the penetration hole 4. The outer contour of the mounting seat 7 is set in the shape of a rectangular parallelepiped. The mounting seat 7 is provided with a through hole with the same outer contour as the penetration hole 4 from its geometric center to its edge. When the mounting seat 7 is installed on the lower shell 12, the through hole and the penetration hole 4 are arranged in opposition, and the cable can pass freely along the through hole and the penetration hole 4.

[0042] Furthermore, a first bearing seat 71 is installed on one side of the mounting seat 7 close to the through hole, and the positioning roller 21 is rotatably connected to the first bearing seat 71 along the vertical direction.

[0043] Correspondingly, a sliding groove is opened along the length direction of the mounting seat 7 which is symmetrical about the bearing seat with the geometric center of the through hole as the boundary, and the sliding plate 31 is slidingly set in the mounting seat 7. At the same time, a second bearing seat 72 is installed on the sliding plate 31, and the adjusting roller 22 is rotatably supported on the second bearing seat 72.

[0044] Meanwhile, the adjusting screw 32 comprises a screw body 321 and a hand wheel 322 . The screw body 321 and the hand wheel 322 are coaxially fixed, and the screw body 321 is threadedly connected to the mounting seat 7 and faces the sliding plate 31 , and is fixedly connected to the sliding plate 31 at the same time.

[0045] Therefore, the operator only needs to rotate the hand wheel 322 clockwise or counterclockwise to adjust the roller 22 to move closer to or away from the positioning roller 21, so that it can meet the positioning requirements of cables with different wire diameters.

[0046] Reference Figure 2 , and also includes a transmission assembly 5, which includes a transmission shaft 51, a first bevel gear 52 and a second bevel gear 53. The transmission shaft 51 is rotatably carried on the box body 1, the first bevel gear 52 is coaxially fixed with the transmission shaft 51, the second bevel gear 53 is coaxially fixed with the positioning roller 21, and the second bevel gear 53 is meshed with the third bevel gear 54.

[0047] Specifically, the transmission shaft 51 is rotatably supported on the mounting seat 7 and is vertically arranged in spatial relationship with the positioning roller 21 and the adjusting roller 22 , because the first bevel gear 52 and the second bevel gear 53 are in a meshing state.

[0048] Therefore, if power (such as a driving motor) is applied to the transmission shaft 51 to drive the transmission shaft 51 to rotate, the first bevel gear 52 coaxially fixed with the transmission shaft 51 rotates synchronously with the transmission shaft 51, and drives the second bevel gear 53 meshing with the first bevel gear 52 to rotate, thereby driving the positioning roller 21 to rotate along the first bearing seat 71. When the cable passes between the positioning roller 21 and the adjusting roller 22, the positioning roller 21 is in a rotating state, thereby reducing the resistance encountered by the cable when passing between the positioning roller 21 and the adjusting roller 22, so that the cable can pass smoothly between the positioning roller 21 and the adjusting roller 22.

[0049] Reference Figure 2The transmission assembly 5 also includes a third bevel gear 54 and a fourth bevel gear 55. The fourth bevel gear 55 is coaxially fixed with the adjusting roller 22. The third bevel gear 54 is meshed with the fourth bevel gear 55. The third bevel gear 54 is keyed with the transmission shaft 51, and the third bevel gear 54 is transitionally matched with the transmission shaft 51. A sliding seat 512 is provided on the transmission shaft 51. The third bevel gear 54 is rotatably connected to the sliding seat 512, and the sliding seat 512 is fixedly connected to the sliding plate 31.

[0050] Specifically, a connecting shaft 8 is coaxially fixedly connected to the third bevel gear 54. In order to improve the stability of the cooperation between the third bevel gear 54 and the connecting shaft 8, the third bevel gear 54 and the connecting shaft 8 are integrally formed, and a pin groove is provided on the inner diameter of the connecting shaft 8. Correspondingly, a pin groove is also provided on the transmission shaft 51. The inner diameter of the connecting shaft 8 is larger than the inner diameter of the transmission shaft 51. The pin groove of the connecting shaft 8 and the pin groove on the transmission shaft 51 are connected by a pin key, and the third bevel gear 54 and the first bevel gear 52 are symmetrically arranged about the midpoint of the distance between the two. Therefore, when the transmission shaft 51 rotates, the power of the transmission shaft 51 is transmitted to the third bevel gear 54 by relying on the cooperation of the pin groove and the pin key. When the transmission shaft 51 rotates, the first bevel gear 52 and the third bevel gear 54 coaxial with the transmission shaft 51 rotate synchronously with the transmission shaft 51.

[0051] Therefore, when the transmission shaft 51 drives the first bevel gear 52 and the third bevel gear 54 to rotate, the first bevel gear 52 and the third bevel gear 54 respectively drive the second bevel gear 53 and the fourth bevel gear 55 meshing therewith to rotate, thereby driving the positioning roller 21 and the adjusting roller 22 to rotate. When the cable passes between the positioning roller 21 and the adjusting roller 22, since the positioning roller 21 and the adjusting roller 22 are both in a rotating state, the cable can be limited when passing between the adjusting roller 22 and the positioning roller 21, and a thrust can be provided to enable the cable to move smoothly.

[0052] Furthermore, a bearing is installed in the inner hole of the sliding seat 512, and the connecting shaft 8 is transitionally fitted with the inner ring of the bearing. The sliding seat 512 is fixedly connected to the sliding plate 31. When the operator turns the hand wheel 322 to make the screw body 321 carry the sliding plate 31 to slide along the mounting seat 7, because the connecting shaft 8 and the transmission shaft 51 are in a transitional fit state, and the third bevel gear 54 and the fourth bevel gear 55 are meshed with each other, when adjusting the distance between the adjusting roller 22 and the positioning roller 21, the third bevel gear 54 and the fourth bevel gear 55 are always in a meshing state, so that the third bevel gear 54 moves synchronously with the sliding plate 31 without the need to adjust the third bevel gear 54 separately, which improves the convenience of overall adjustment to a certain extent.

[0053] Reference Figure 2The limiting assembly 2 also includes a transverse auxiliary roller 23, which is rotatable in the horizontal direction and is carried on the box body 1 at the penetration hole 4. An adjustment seat 6 is provided on the box body 1 at the penetration hole 4. The adjustment seat 6 has an adjustment groove 61 along its vertical direction. The transverse auxiliary roller 23 can be adjusted upward or downward along the adjustment groove 61.

[0054] Specifically, the lateral auxiliary roller 23 includes a roller shaft 232 and a roller body 231 . The roller body 231 is rotatably supported on the roller shaft 232 , and threads are respectively provided at both ends of the roller shaft 232 .

[0055] Furthermore, the adjustment seat 6 is installed on the mounting plate, and two adjustment slots 61 are provided. The two adjustment slots 61 are respectively opened on the two side walls of the adjustment seat 6 along the vertical direction, and the two adjustment slots 61 are symmetrically arranged about the geometric center of the adjustment seat 6 along its width direction.

[0056] Therefore, when both ends of the roller shaft 232 are placed in the two adjustment grooves 61, since both ends of the roller shaft 232 are respectively provided with threads, the roller shaft 232 can be fixed to the adjustment plate through nuts, so that the roller shaft 232 can carry the roller body 231 to stably rotate along the adjustment seat 6.

[0057] Through the above process, when the cable moves along the transverse auxiliary roller 23, since the transverse auxiliary roller 23 is in a rotating state, the friction of the cable when moving along the transverse auxiliary roller 23 is reduced, so that the cable can slide smoothly along the transverse auxiliary roller 23, and at the same time, it can reduce the scratches or scratches on the cable during the movement, and play a positive guiding role in improving the appearance quality of the cable.

[0058] The implementation principle of a wire sheath damage detection device in an embodiment of the present application is as follows: when it is necessary to detect cables with different wire diameters, the operator can rotate the hand wheel 322 to make the sliding plate 31 carrying the adjusting roller 22 slide along the mounting seat 7, so that the adjusting roller 22 approaches or moves away from the positioning roller 21, so that the positioning roller 21 and the specific cable in the bracket of the adjusting roller 22 can pass smoothly; for some cables with larger wire diameters, a driving device (such as a driving motor, etc.) can be applied to the transmission shaft 51, so that the first bevel gear 52 coaxially fixed with the transmission shaft 51 rotates synchronously with the transmission shaft 51, and the power of the transmission shaft 51 is transmitted to the positioning roller 21 through the second bevel gear 53. , so that the positioning roller 21 rotates, providing power for the cable to pass through. At the same time, for cables with relatively small wire diameters, when the cable passes between the positioning roller 21 and the adjusting roller 22, due to the rolling friction between the cable and the contact surfaces of the positioning roller 21 and the adjusting roller 22, and the third bevel gear 54 is coaxially fixed with the transmission shaft 51, the positioning roller 21 and the adjusting roller 22 are rotated synchronously through the second bevel gear 53 and the fourth bevel gear 55, so that the cable can move stably between the adjusting roller 22 and the positioning roller 21. Through the coordinated cooperation of the positioning roller 21 and the adjusting roller 22, the shaking of the cable during detection is greatly reduced, which plays a positive guiding role in improving the accuracy of the detection results of the detection component.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
