Description

Technical Field

[0001] The invention relates to the technical field of cable detection, in particular to a conductor device used for an industrial frequency spark machine. Background Art

[0002] The power frequency spark machine is mainly used to detect the poor insulation points of bare copper, broken skin, pinholes, etc. of various cables, and mark the poor points at the same time to achieve better quality results. It is suitable for the detection of insulation performance of wires and cables in online production. It has the characteristics of stable output high voltage, high detection sensitivity, no error in breakdown counting, strong anti-interference, and obvious breakdown points. A wire device will be used at the end of the detection channel of the power frequency spark machine to pull the cable to be tested.

[0003] In the prior art, guide wheels are directly installed at both ends of the industrial frequency spark machine to support and guide the cable. However, due to the influence of factors such as cable surface deformation, wear, slippage or external force interference, the cable part inside the threading channel of the industrial frequency spark machine often appears too tight or loose, making it impossible for the subsequent cable to be in the middle position of the detection electrode sheet, reducing the accuracy of the detection. On the other hand, since the cable moves in a straight line and the position of the electrode sheet is fixed, when the broken skin position on the cable is straight and parallel to the cable, there is a certain probability that the broken skin position passes through the gap between the electrode sheets and cannot be detected. Therefore, there is a certain detection blind spot in the traction process of the wire device. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6The present invention provides the following technical solutions: a wire guide device for an industrial frequency spark machine, comprising a wire threading channel 2, a machine platform 1 and a wire guide device body, the wire guide device body comprising an introduction mechanism 3, an export mechanism 4, a slack detection component 5 and a clamping adjustment mechanism 6, the wire threading channel 2 is fixedly mounted on the top of the machine platform 1, and the two ends of the machine platform 1 are respectively provided with an introduction mechanism 3 and an export mechanism 4, side plates 8 are installed on both sides of the export mechanism 4, a driving shaft 10 is installed on the inner side of the side plate 8, a clamping adjustment mechanism 6 is installed in the middle of the wire threading channel 2, the slack detection component 5 is installed on one side of the clamping adjustment mechanism 6, and a conductive detection element 7 is arranged on the other side of the clamping adjustment mechanism 6, a linkage shaft 15 is connected to the top of the conductive detection element 7, the end of the linkage shaft 15 passes outward from the end of the wire threading channel 2, and the end of the linkage shaft 15 is connected to the export mechanism 4 part. When the wire device for the industrial frequency spark machine is used, the cable to be tested is inserted from one end of the introduction mechanism 3 into the interior of the threading channel 2, and then passes through the slack detection component 5, the clamping adjustment mechanism 6, and the conductive detection element 7 in the interior of the threading channel 2 in turn, and finally passes out from the external lead-out mechanism 4. In this process, with the help of the slack detection component 5 and the clamping adjustment mechanism 6, timely adjustment and correction can be made for the phenomenon that the cable is too tight or loose during transportation, and the lead-out mechanism 4 can directly link the conductive detection element 7 to rotate with the help of multiple sets of gear transmission structures. Therefore, when the wire passes through the interior of the conductive detection element 7, the electrode sheet 26 used for detection will rotate, so the path of the end of the electrode sheet 26 on the insulating layer on the surface of the cable will be spiral, ensuring that the straight-line broken skin area on the cable can also be accurately detected with the help of the spiral detection path.

[0028] In this embodiment, the output mechanism 4 includes an output clamping guide roller 12 and a drive shaft 10, one end of the drive shaft 10 is equipped with a motor 9, two output clamping guide rollers 12 are provided, and one end of the upper output clamping guide roller 12 and the surface of the drive shaft 10 are equipped with a first gear 13, a first toothed belt 14 is connected between the two first gears 13, a first bevel gear 11 is installed in the middle of the drive shaft 10, a second bevel gear 16 is installed at the end of the linkage shaft 15, and the first bevel gear 11 and the second bevel gear 16 are meshed, the housing part of the motor 9 is fixed to the outer side of the side plate 8 with screws, and the ends of the output clamping guide rollers 12 are embedded in the inner side of the side plate 8 through bearings.

[0029] Specifically, when the cable to be tested is to be led out, the motor 9 is started, and the motor 9 drives the driving shaft 10 to rotate. After the driving shaft 10 rotates, the output clamping guide roller 12 at the bottom can be driven to rotate through the first gear 13 and the first toothed belt 14 on the surface. Since the cable to be tested is clamped and conveyed by the output clamping guide roller 12, power can be provided at this position to lead out the cable to be tested. At the same time, the first bevel gear 11 on the driving shaft 10 is meshed with the second bevel gear 16 on the linkage shaft 15. Therefore, after the driving shaft 10 rotates, it can also drive the linkage shaft 15 to rotate synchronously with the meshing structure of the above-mentioned bevel gears, and finally drive the conductive detection element 7 to rotate with the help of the linkage shaft 15.

[0030] In this embodiment, the conductive detection element 7 includes a conductive sleeve 25 and an electrode sheet 26, the electrode sheet 26 is installed inside the conductive sleeve 25, and the surface of the conductive sleeve 25 is sleeved with a bottom support bearing 27, and the conductive sleeve 25 area between the two bottom support bearings 27 is provided with a gear ring 29, one end of the surface of the conductive sleeve 25 is installed with a brush 28, the bottom of the outer ring of the bottom support bearing 27 is fixed to the bottom end of the threading channel 2 through a rod, the surface of the linkage shaft 15 is installed with a second gear 23, the linkage shaft 15 on both sides of the second gear 23 is sleeved with a top support bearing 22, and the outer ring part of the top support bearing 22 is fixedly connected to the top of the inner wall of the threading channel 2, the surface of the second gear 23 is sleeved with a second toothed belt 24, the other end of the second toothed belt 24 is sleeved on the gear ring 29, and a plurality of electrode sheets 26 are provided, and the end of each electrode sheet 26 contacts the surface of the cable to be tested. The cable is pulled out and transported by the lead-out mechanism 4, and at the same time, the driving shaft 10 and the bevel gear at the top can also be linked to the conductive detection element 7 for synchronous movement, so that each electrode sheet 26 rotates, and the detection path of the electrode sheet 26 on the surface of the wire is spiral, eliminating the problem of blind angles in detection.

[0031] Specifically, after the linkage shaft 15 is driven to rotate by the above-mentioned drive, the second gear 23 on the linkage shaft 15 cooperates with the second toothed belt 24 to drive the gear ring 29 to rotate. The conductive sleeve 25 on the gear ring 29 is supported by the bottom support bearing 27 on the surface. Therefore, it can rotate after the transmission of the gear ring 29. After the conductive sleeve 25 rotates, each electrode sheet 26 on the inside can be driven to rotate. The cable to be tested passing through the inside in the rotating state can form a spiral detection path on the surface, and after detecting the broken skin area, the electrical signal is transmitted to the outside through the brush 28 at one end, so as to achieve the effect of detecting the broken skin area.

[0032] In this embodiment, the clamping and adjusting mechanism 6 includes an electric telescopic rod 19 and a fixed seat 17. A pressure monitoring module 18 is installed inside the fixed seat 17. The electric telescopic rod 19 is installed at the bottom of the fixed seat 17. A movable strut 20 is installed at the end of the electric telescopic rod 19. A fixed strut 21 is installed on the inner wall of the threading channel 2. Two fixed struts 21 are provided, and the two fixed struts 21 are symmetrically arranged on both sides of the electric telescopic rod 19. The top of the fixed seat 17 is fixedly connected to the top of the inner wall of the threading channel 2. If the cable inside the threading channel 2 is too tight or loose, it can be automatically corrected. When the cable is too tight, the pressure monitoring module 18 can be used to control the compression and adjusting mechanism 6 to shrink, so as to avoid the situation where the tension causes damage to the cable surface. When the cable is too loose, it can also be detected by the loose detection component 5 to ensure that it can be tightened in time.

[0033] Specifically, when the internal cable to be tested is too tensioned, the tension of the cable to be tested itself will act on the bottom of the movable support rod 20 and exert an upward thrust, and then the pressure change can be detected by the pressure monitoring module 18 on the top. Therefore, when the pressure is too high, the electric telescopic rod 19 can be controlled to contract and shorten the length of the cable to be tested inside the threading channel 2. This process can relieve the tension state and avoid deformation or even breakage of the cable to be tested due to excessive tension.

[0034] In this embodiment, the slack detection component 5 includes a pressure rod 30 and a conductive sheet 33, spring rods 31 are inserted at both ends of the pressure rod 30, and one end of the pressure rod 30 is connected to a conductive column 32, an insulating plate 36 is arranged on the top of the conductive sheet 33, a lifting groove 35 is opened inside the conductive sheet 33, a screw rod 34 is inserted on the top of the insulating plate 36, the top end of the screw rod 34 extends outward from the top of the threading channel 2, the end of the conductive column 32 is embedded in the lifting groove 35, and the surface of the conductive column 32 is in contact with the surface of the conductive sheet 33, the bottom end of the spring rod 31 is installed on the bottom end of the inner wall of the threading channel 2, threaded holes are opened at both ends of the top of the insulating plate 36, and the screw rod 34 passes through the threaded holes on the insulating plate 36. The slack detection component 5 can control the height of the conductive sheet 33 from the outside, and thereby control the degree of slack required for the internal cable to be reached when triggering the clamping adjustment mechanism 6 to perform the tensioning process. With the help of this structure, the triggering range of the clamping adjustment mechanism 6 can be controlled according to the length of the electrode sheet 26 in the conductive detection element 7 and the diameter of the cable, thereby further improving the stability and flexibility of continuous cable monitoring.

[0035] Specifically, when the cable to be tested is too loose, it will fall, which will cause the pressure on the pressure rod 30 to increase, the spring rod 31 to contract, and the conductive column 32 at the end to move downward until the conductive column 32 is out of the lifting groove 35. At this time, the disconnection between the conductive column 32 and the conductive sheet 33 can trigger the extension of the electric telescopic rod 19 through the disconnection of the electrical signal, thereby extending the length of the cable to be tested in the threading channel 2, thereby alleviating the relaxation problem, so that the conductive column 32 moves up and finally contacts the conductive sheet 33 again, and the position of the lifting groove 35 can be controlled by rotating the control screw 34. After the lifting groove 35 is adjusted to move downward, the conductive column 32 can be moved down to a lower position to trigger the relaxation control signal.
