Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and in particular to a cable detection device. Background Art

[0002] Cable is an important part of my country's power system and a transmission material mainly used for communication and electricity. During the production process, cables and wires are affected by factors such as extrusion temperature, extrusion speed and cross-linking speed, which can easily lead to the phenomenon of raw rubber, making the surface of the cable insulation layer uneven, and then bulging. The bulging position of the cable is very easy to be damaged and aged, and the cables and wires may also be damaged during the production process. The damaged position will cause leakage. Therefore, the cable needs to be inspected for quality after production, so as to check the bulging and damaged positions on the cable, screen out defective cables, and improve the factory quality of the cable.

[0003] After searching, the patent publication number CN116429774B discloses "a cable detection device and detection method for cable production", including a mounting frame, side mounting frames are fixedly installed at the middle positions of the left and right sides of the mounting frame, the inner front end of the side mounting frame is installed with a clamping and fixing mechanism for fixing the cable, and a marking mechanism for marking the damaged position of the cable is arranged at the middle position of the side mounting frame, a shooting mechanism is arranged at the rear end of the marking mechanism on the inner side of the side mounting frame, and an auxiliary mechanism is arranged at the inner rear end of the side mounting frame. The device is provided with a marking mechanism, when there is a depression on the surface of the cable, the spraying mechanism will spray the paint from the end of the first spraying chamber to mark the depressed position, and when there is a protrusion on the surface of the cable, the spraying mechanism will spray the paint from the end of the second spraying chamber to mark the protrusion, so as to facilitate the subsequent picture recognition of the damaged position on the cable surface.

According to the transmitted pictures, it is judged whether there are bulges or damages on the cable surface. However, the surface color of the cable is darker, and it is difficult to compare the position of the bulges or damages only by camera shooting, which leads to low detection accuracy and missed detection and misjudgment. The detection accuracy is poor. At the same time, there are certain requirements for the number of cameras, resulting in higher overall cost of the equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a cable detection device, which not only reduces the requirement on the number of cameras and cuts the equipment cost, but also improves the detection accuracy, greatly reduces the risk of missed detection and misjudgment, and improves the accuracy of detection.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a cable detection device, comprising: a base, a wire supply roller and a wire take-up roller rotatably mounted on the top of the base, and a box with a wire inlet and a wire outlet disposed between the wire supply roller and the wire take-up roller; A limiting cylinder is rotatably installed on one side of the box body and close to the inlet and outlet, and the two limiting cylinders are connected with the inlet and outlet. An ink storage box is fixedly connected to one side of the two limiting cylinders through a connecting rod, and a camera, a distance sensor and an inkjet gun connected to the ink storage box are arranged on the side of the ink storage box opposite to the inner wall of the box body; A first driven shaft and a second driven shaft are symmetrically arranged on the inner wall of the box and about the ink storage box, and the first driven shaft and the second driven shaft are connected by a belt drive. A transmission mechanism for driving the limiting cylinder to rotate is arranged between the first driven shaft, the second driven shaft and the corresponding limiting cylinder, and a driving mechanism for driving the first driven shaft to rotate is arranged outside the box.

[0008] 2. In the above scheme, the driving mechanism includes: a rotating motor installed on the outer wall of the box body, a half gear installed on the output shaft of the rotating motor, and one end of the first driven shaft can extend through the box body and is fixedly connected to a first driven gear meshing with the half gear.

[0009] 3. In the above solution, the wire supply roller is rotatably installed between two first fixed plates, and the wire take-up roller is rotatably installed between two second fixed plates.

[0010] 4. In the above scheme, the take-up roller and the second fixed plate are rotatably connected via a rotating shaft, and a second driven gear meshing with a half gear is installed at the end of the rotating shaft away from the take-up roller, and the half gear is located between the first driven gear and the second driven gear.

[0013] 7. In the above scheme, a pulley is respectively installed on the circumferential outer wall of the first driven shaft and the second driven shaft, and the belt is sleeved between the two pulleys.

[0014] 8. In the above solution, a plurality of balls are arranged inside the limiting cylinder and along its circumference.

[0015] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: 1. The cable detection device of the present invention is located on one side of two limit cylinders and is fixedly connected to an ink storage box through a connecting rod. A camera, a distance sensor and an inkjet gun connected to the ink storage box are arranged on the side of the ink storage box opposite to the inner wall of the box body. A processor with a preset value is connected to the camera, the distance sensor and the inkjet gun. The first driven shaft and the second driven shaft drive the two limit cylinders to rotate through a transmission mechanism respectively. The ink storage box located between the two limit cylinders makes a circular motion around the cable between the two limit cylinders, so that the circumference of the cable between the two limit cylinders can be photographed.

The two limit cylinders are driven to move synchronously by the first driven shaft and the second driven shaft, which is beneficial to improving the rotation stability of the camera and the distance sensor, ensuring the position accuracy between the camera, the distance sensor and the cable, further improving the detection accuracy, and helping to improve the accuracy of detection.

[0016] 2. The cable detection device of the present invention has a wire supply roller rotatably installed between two first fixed plates, and a wire take-up roller rotatably installed between two second fixed plates; the wire take-up roller and the second fixed plate are rotatably connected via a rotating shaft, and a second driven gear meshing with a half gear is installed at the end of the rotating shaft away from the wire take-up roller, and the half gear is located between the first driven gear and the second driven gear. The wire take-up roller and the limit cylinder are driven to rotate by a rotating motor, and the half gear is meshed with the first driven gear on the first driven shaft and the second driven gear on the rotating shaft. The wire take-up roller can be prevented from rotating while the limit cylinder is driven to rotate, and the limit cylinder stops rotating when the wire take-up roller rotates to take up the wire, thereby realizing intermittent movement of the cable. While reducing the requirements for camera shooting, the risk of missed detection is further reduced, thereby improving the reliability of detection. BRIEF DESCRIPTION OF THE DRAWINGS

An ink storage box 12 is located on one side of the two limiting cylinders 19 and is fixedly connected through a connecting rod 15. A camera 14, a distance sensor 13 and an inkjet gun 20 connected to the ink storage box 12 are arranged on the side of the ink storage box 12 opposite to the inner wall of the box 1. A processor with a preset value is connected to the camera 14, the distance sensor 13 and the inkjet gun 20; By using a camera to rotate around the cable to take pictures, the number of cameras required is reduced, and the equipment cost is cut. In addition, images and distance information can be collected during the rotation process as a basis for judgment, and the corresponding positions can be marked according to the judgment results, which is convenient for subsequent inspections by personnel, greatly reducing the risk of missed detection and misjudgment, and improving the accuracy of detection; A first driven shaft 2 and a second driven shaft 25 are symmetrically arranged on the inner wall of the box body 1 and about the ink storage box 12, and the first driven shaft 2 and the second driven shaft 25 are connected by a belt 26, and a transmission mechanism for driving the limiting cylinder 19 to rotate is arranged between the first driven shaft 2, the second driven shaft 25 and the corresponding limiting cylinder 19, and a driving mechanism for driving the first driven shaft 2 to rotate is arranged outside the box body 1; During the detection process, the rotating motor is started to drive the half gear to rotate. The half gear first meshes with the first driven gear to drive it to rotate one circle. The first driven gear drives the first driven shaft to rotate. The first driven shaft drives the second driven shaft to rotate through the pulley and the belt. The first driven shaft and the second driven shaft drive the supporting shaft to rotate through the meshing of the driving bevel gear and the driven bevel gear. The supporting shaft drives the linkage gear to rotate. The linkage gear drives the two limit cylinders to rotate one circle through a plurality of convex teeth. The two limit cylinders drive the ink storage box to rotate one circle around the cable passing through the middle of the box through the connecting rod.

[0021] The transmission mechanism includes: a convex tooth 16 sleeved on the limiting cylinder 19, a support shaft 22 rotatably mounted on one side of the convex tooth 16, a linkage gear 23 meshing with the convex tooth 16 and a driven bevel gear 21 are mounted on the support shaft 22, and an active bevel gear 24 cooperating with the driven bevel gear 21 is respectively mounted on the end of the first driven shaft 2 and the second driven shaft 25.

[0022] The driving mechanism comprises a rotating motor 5 mounted on the outer wall of the housing 1 and a half gear 4 mounted on the output shaft of the rotating motor 5. One end of the first driven shaft 2 can extend through the housing 1 and is fixedly connected to a first driven gear 3 meshing with the half gear 4.

[0023] The wire supply roller 10 is rotatably mounted between two first fixed plates 29 , and the wire take-up roller 9 is rotatably mounted between two second fixed plates 30 .

[0024] The take-up roller 9 is rotatably connected to the second fixed plate 30 via a rotating shaft 7, and a second driven gear 6 meshing with the half gear 4 is installed at one end of the rotating shaft 7 away from the take-up roller 9, and the half gear 4 is located between the first driven gear 3 and the second driven gear 6; After the detection is completed, the half gear meshes with the second driven gear to drive it to rotate one circle.

This reciprocating process can complete the continuous detection of the cable without manual operation, saving time and effort. Moreover, the all-round detection and reeling of the cable are completed by only one driving motor and the cooperation mechanism, and the mechanism has higher linkage.

[0025] The above-mentioned limiting cylinder 19 is rotatably installed inside a supporting ring 17, and the supporting ring and the limiting cylinder 19 are arranged concentrically.

[0026] A support rod 18 is provided between the inner bottom wall of the box body 1 and the support ring 17 .

[0027] A pulley 31 is respectively installed on the circumferential outer wall of the first driven shaft 2 and the second driven shaft 25 , and the belt 26 is sleeved between the two pulleys 31 .

[0028] Embodiment 2: A cable detection device, comprising: a base 28, a wire supply roller 10 and a wire take-up roller 9 rotatably mounted on the top of the base 28, and a box 1 with a wire inlet 11 and a wire outlet 8 disposed between the wire supply roller 10 and the wire take-up roller 9; A limiting cylinder 19 is rotatably installed inside the box 1 and on one side close to the wire inlet 11 and the wire outlet 8, and the two limiting cylinders 19 are connected with the wire inlet 11 and the wire outlet 8. An ink storage box 12 is located on one side of the two limiting cylinders 19 and is fixedly connected through a connecting rod 15. A camera 14, a distance sensor 13 and an inkjet gun 20 connected to the ink storage box 12 are arranged on the side of the ink storage box 12 opposite to the inner wall of the box 1. A processor with a preset value is connected to the camera 14, the distance sensor 13 and the inkjet gun 20; During the rotation of the ink storage box, the camera at the bottom of the ink storage box first takes a picture of the cable, and then uses the distance sensor to measure the distance from the cable. The taken pictures and distance data are transmitted to the background for comparison and detection. Once the pictures and distance data are abnormal, the inkjet gun is started to spray ink on the abnormal part of the cable to facilitate the staff to check. The cable is detected by using both picture and distance detection methods, which has higher detection accuracy, avoids missing or misjudging the position of protrusions or damage, and reduces the workload of the staff. At the same time, when the ink storage box rotates, the camera, distance sensor and inkjet gun at the bottom of the ink storage box are driven to rotate around the cable, so as to detect the cable in all directions without dead angles, without the need for multiple sets of detection equipment, and reducing equipment costs; A first driven shaft 2 and a second driven shaft 25 are symmetrically arranged on the inner wall of the box body 1 and about the ink storage box 12, and the first driven shaft 2 and the second driven shaft 25 are connected by a belt 26, and a transmission mechanism for driving the limiting cylinder 19 to rotate is arranged between the first driven shaft 2, the second driven shaft 25 and the corresponding limiting cylinder 19, and a driving mechanism for driving the first driven shaft 2 to rotate is arranged outside the box body 1; The two limit cylinders are driven to move synchronously by the first driven shaft and the second driven shaft, which is beneficial to improving the rotation stability of the camera and the distance sensor and improving the position accuracy between the camera, the distance sensor and the cable.

[0029] The transmission mechanism includes: a convex tooth 16 sleeved on the limiting cylinder 19, a support shaft 22 rotatably mounted on one side of the convex tooth 16, a linkage gear 23 meshing with the convex tooth 16 and a driven bevel gear 21 are mounted on the support shaft 22, and an active bevel gear 24 cooperating with the driven bevel gear 21 is respectively mounted on the end of the first driven shaft 2 and the second driven shaft 25.

[0030] The driving mechanism comprises: a rotating motor 5 mounted on the outer wall of the housing 1, a half gear 4 mounted on the output shaft of the rotating motor 5, one end of the first driven shaft 2 can extend through the housing 1 and is fixedly connected with a first driven gear 3 meshing with the half gear 4; The limit cylinder can be driven to rotate while the take-up roller is prevented from rotating. When the take-up roller rotates to take up the wire, the limit cylinder stops rotating, thereby realizing intermittent movement of the cable. While reducing the requirements for camera shooting, it further reduces the risk of missed detection and improves the reliability of detection.

[0031] The take-up roller 9 is rotationally connected to the second fixed plate 30 via a rotating shaft 7, and a second driven gear 6 meshing with the half gear 4 is installed at the end of the rotating shaft 7 away from the take-up roller 9, and the half gear 4 is located between the first driven gear 3 and the second driven gear 6.

[0032] The above-mentioned limiting cylinder 19 is rotatably installed inside a supporting ring 17, and the supporting ring and the limiting cylinder 19 are arranged concentrically.

[0033] A support rod 18 is provided between the inner bottom wall of the box body 1 and the support ring 17 .

[0034] A pulley 31 is respectively installed on the circumferential outer wall of the first driven shaft 2 and the second driven shaft 25 , and the belt 26 is sleeved between the two pulleys 31 .

[0035] A plurality of balls 27 are disposed inside the limiting cylinder 19 and along its circumference.

[0036] The working principle is: When in use, the supply roller provides the cable to enter the box from the cable inlet, the cable passes through the two limiting cylinders in turn, then is discharged from the cable outlet and then reeled on the take-up roller, and the cable between the two limiting cylinders is kept in a straight state; During the detection process, the rotating motor is started to drive the half gear to rotate, the half gear first meshes with the first driven gear to drive it to rotate one circle, the first driven gear drives the first driven shaft to rotate, the first driven shaft drives the second driven shaft to rotate through the pulley and the belt, the first driven shaft and the second driven shaft drive the support shaft to rotate through the meshing of the driving bevel gear and the driven bevel gear, the support shaft drives the linkage gear to rotate, the linkage gear drives the two limit cylinders to rotate one circle through a plurality of convex teeth, the two limit cylinders drive the ink storage box to rotate one circle around the cable passing through the middle of the box body through the connecting rod; During the rotation of the ink storage box, the camera at the bottom of the ink storage box first takes a picture of the cable, and then uses the distance sensor to measure the distance from the cable. The taken pictures and distance data are transmitted to the background for comparison and detection. Once the pictures and distance data are abnormal, the inkjet gun is started to spray ink on the abnormal part of the cable to facilitate the staff to check. The cable is detected by using both picture and distance detection methods, which has higher detection accuracy, avoids missing or misjudging the position of protrusions or damage, and reduces the workload of the staff. At the same time, when the ink storage box rotates, the camera, distance sensor and inkjet gun at the bottom of the ink storage box are driven to rotate around the cable, so as to detect the cable in all directions without dead angles, without the need for multiple sets of detection equipment, and reducing equipment costs; After the detection is completed, the half gear meshes with the second driven gear to drive it to rotate one circle. The second driven gear drives the take-up roller to rotate one circle through the rotating shaft to reel up the cable one circle, thereby moving the undetected cable to the bottom of the detection equipment. This reciprocating process can complete the continuous detection of the cable without manual operation, saving time and effort. Moreover, the all-round detection and reeling of the cable are completed by only one driving motor and the cooperation mechanism, and the mechanism has higher linkage.

[0037] When the above-mentioned cable detection device is used, the ink storage box located between the two limit cylinders moves in a circular motion around the cable between the two limit cylinders, so that the circumference of the cable between the two limit cylinders can be photographed. At the same time, the distance sensor measures the distance between the circumferential outer wall of the cable and the sensor during the rotation process. By rotating one camera around the cable to take pictures, the number of cameras required is reduced, and the equipment cost is reduced. It is also possible to collect images and distance information as a basis for judgment during the rotation process, and mark the corresponding position according to the judgment result, which is convenient for personnel to conduct subsequent inspections, greatly reducing the risk of missed detection and misjudgment, and improving the accuracy of detection; further, it drives the two limit cylinders to move synchronously through the first driven shaft and the second driven shaft, which is conducive to improving the stability of the rotation of the camera and the distance sensor, ensuring the position accuracy between the camera, the distance sensor and the cable, thereby improving the detection accuracy, greatly reducing the risk of missed detection and misjudgment, and helping to improve the accuracy of detection; Furthermore, it can prevent the take-up roller from rotating while driving the limit cylinder to rotate, and when the take-up roller rotates to take up the wire, the limit cylinder stops rotating, thereby realizing intermittent movement of the cable. While reducing the requirements for camera shooting, it further reduces the risk of missed detection and improves the reliability of detection.
