Description

Technical Field

[0001] The utility model belongs to the technical field of electric wires and cables, and in particular relates to a cable surface cleaning and defect detection device. Background Art

[0002] In the field of railway transportation, rolling stock, as a vital means of transportation, has a safety and reliability that is directly linked to the proper functioning of the entire transportation system. Cables, as core components of the electrical system, carry out crucial functions such as signal transmission and power supply. Their proper functioning is directly linked to the safety and reliability of the electrical system. Over time and with the use of rolling stock, the insulation material on the cable surface will naturally age, cracking, discoloring, and other phenomena. Regular inspections can identify cable defects and potential hazards, preventing electrical system failures and ensuring the safe operation of rolling stock.

[0003] In existing cable detection systems, detection units typically rely on industrial cameras, image recognition algorithms, and other technical means to identify cables. However, during the operation of locomotives and vehicles, dust, oil, and other pollutants in the atmosphere will also adhere to the surface of the cables. Various stains often adhere to the surface of the cables, obscuring the surface features of the cables and making it difficult for the detection unit to accurately capture and identify relevant information about the cables, such as size, shape, and markings. Traditional cable cleaning equipment focuses primarily on basic cleaning of ordinary cable surfaces and does not incorporate cable defect detection into its design to reduce unnecessary damage to the cables caused by excessive cleaning. However, after long-term use of the cables, this may also result in some stubborn stains that cannot be completely removed. In this case, the stains have a serious impact on the surface defect detection of the cables, greatly reducing the recognition accuracy and efficiency of the detection system, and may even lead to misjudgments and missed detections, posing a hidden danger to the quality inspection and use safety of locomotive and vehicle cables.

[0036] Example

[0037] The utility model provides a cable surface cleaning and defect detection device, which is used to solve the technical problem that stains attached to the cable surface easily affect the detection of cable surface defects during current cable surface defect detection. The cable surface cleaning and defect detection device includes a frame 1, a transmission mechanism 4, a first cleaning mechanism 2, a second cleaning mechanism 3 and a detection unit 8, wherein:

[0038] like Figure 1-2 As shown, the rack 1 is used to support other components, and the cables to be cleaned are transported along the extension direction of the rack 1 . When the cables are being cleaned, they are located above the rack 1 .

[0039] like Figure 1As shown, the transmission mechanism 4 is arranged on the frame 1. Specifically, the transmission mechanism 4 is located at one end of the frame 1. The transmission mechanism 4 is used to drive the cable to move so as to transport the cable from the end of the bracket away from the frame 1 to the transmission mechanism 4. The transmission mechanism 4 can be a winding machine, a traction machine, etc. The cable is covered with an insulating layer to protect the internal wire.

[0040] like Figure 1-2 As shown, the first cleaning mechanism 2 is installed on the bracket by bolting or the like. The first cleaning mechanism 2 is used to clean the insulation layer of the cable. Optionally, the first cleaning mechanism 2 can be a scraper, which abuts against the outer wall of the peripheral side of the insulation layer of the cable, and the cable and the scraper move relative to each other, thereby scraping off the stains on the surface of the cable. The first cleaning mechanism 2 can also be a cleaning brush, which abuts against the cable, and the cleaning brush moves relative to the cable, thereby cleaning the stains on the surface of the cable, thereby completing the cleaning of the stains on the surface of the cable, thereby reducing the stains attached to the cable. The first cleaning mechanism 2 can also be other components that can clean the cable.

[0041] like Figure 1-2 As shown, the second cleaning mechanism 3 is installed on the bracket by bolting or the like. The second cleaning mechanism 3 is located downstream along the cable transmission direction. The second cleaning mechanism 3 is used for the cable insulation layer after being cleaned by the first cleaning mechanism 2, that is, after the first cleaning mechanism 2 completes the cleaning of the cable insulation layer, the second cleaning mechanism 3 cleans the cable insulation layer again, further reducing the stains attached to the cable, thereby improving the cleaning effect of the cable. The second cleaning mechanism 3 can be a sponge 6, which abuts against the insulation layer of the cable, and the sponge 6 and the cable move relative to each other, so that the sponge 6 cleans the cable insulation layer. The second cleaning mechanism 3 can also be an air gun, which sprays high-pressure gas and uses high-pressure gas such as compressed air to blow away dust and dirt on the surface of the cable. The second cleaning mechanism 3 can also be other components that can clean the cable. It is worth noting that the use of the first cleaning mechanism 2 and the second cleaning mechanism 3 should avoid damaging the cable and affecting the normal use of the cable. The first cleaning structure 2 and the second cleaning mechanism 3 further reduce the stains attached to the cable through multi-stage cleaning of the locomotive vehicle cables.

[0042] The detection unit 8 is installed on the bracket and is located downstream of the second cleaning mechanism 3. The detection unit 8 is used to detect the outer peripheral surface of the insulation layer and record the defect position of the insulation layer, so as to determine the defect position of the insulation layer, so as to facilitate the inspection and maintenance of the defect position. Preferably, an alarm can be installed on the detection unit 8. When the detection unit 8 detects the defect position of the insulation layer, the alarm emits an audible and visual alarm to remind the maintenance personnel that a defect position appears on the cable, thereby facilitating the maintenance personnel to perform maintenance. The detection unit can be a camera, an ultrasonic detector or a vision-based surface defect detection system, etc.

[0043] Through the above structure, the cable surface cleaning and defect detection device provided by the present invention, when inspecting the cables of a locomotive vehicle, the transmission mechanism 4 drives the cable to move. Under the transmission of the transmission mechanism 4, the cable first passes through the first cleaning mechanism 2, which cleans the surface of the cable insulation layer. Then, the cable passes through the second cleaning mechanism 3, which cleans the surface of the cable again, thereby reducing the stains attached to the cable. As the transmission mechanism 4 continues to transport, the cable moves to the detection unit 8, which inspects the insulation layer of the cable and records the defect location of the insulation layer. Therefore, the cable surface cleaning and defect detection device further reduces the stains attached to the cable by cleaning the cable multiple times, thereby reducing the impact of the stains on the recognition of the detection unit 8, thereby making the detection unit 8 better at identifying the cable surface, improving the detection unit 8's recognition effect of cable surface defects, reducing the detection unit 8's misjudgment or omission of the cable defect location, and further improving the operating safety of the locomotive vehicle.

[0044] An optional implementation of this embodiment is as follows: the first cleaning mechanism 2 includes a plurality of first cleaning rollers 21, such as Figure 1-2 As shown, multiple first cleaning rollers 21 are mounted on a bracket, and multiple first cleaning rollers 21 are arranged on both sides of the cable along the radial direction of the cable, that is, the axial direction of the first cleaning roller 21 is perpendicular to the extension direction of the cable, and the axial direction of the first cleaning roller 21 is perpendicular to the radial direction of the cable. Multiple first cleaning rollers 21 perpendicular to the radial directions of different cables can increase the contact area between the first cleaning roller 21 and the insulation layer of the cable, so that the first cleaning roller 21 can better clean the stains on the insulation layer; Figure 2 、 Figure 6 as well as Figure 7 As shown, in this embodiment, at least two first cleaning rollers 21 are provided perpendicular to the same radial direction of the cable, that is, the two first cleaning rollers 21 are arranged on both sides of the cable, and the two first cleaning rollers 21 are perpendicular to the same radial direction of the cable, so that when the first cleaning rollers 21 clean the cable, two first cleaning rollers 21 can be installed in the same circumferential direction of the cable to reduce the mutual interference of the first cleaning rollers 21 in the same circumferential direction; further, the distance between the two first cleaning rollers 21 perpendicular to the same radial direction of the cable is adjustable, so as to be suitable for cables of different sizes, or to adjust the pressure between the first cleaning rollers 21 and the cable, thereby changing the cleaning effect of the cable; as shown in FIG. Figure 2As shown, there can be multiple first cleaning rollers 21 perpendicular to the same radial direction of the cable, and the multiple first cleaning rollers 21 are arranged along the extension direction of the cable; more preferably, the distances between the multiple first cleaning rollers 21 perpendicular to the same radial direction of the cable are different, so that the pressures of different first cleaning rollers 21 on the cable are different, thereby improving the cleaning effect of the first cleaning roller 21 on the cable; more preferably, multiple first cleaning rollers 21 are provided along the extension direction of the cable, and the multiple first cleaning rollers 21 have different angles with the cable, so that as the cable moves, the multiple first cleaning rollers 21 increase the contact area with the cable in the same circumferential direction, thereby improving the cleaning effect of the cable.

[0045] An optional implementation of this embodiment is as follows: Figure 6-7 As shown, a brush 5 is provided on the roller wall surface of the first cleaning roller 21. The brush 5 is used to brush the surface of the cable. The brush 5 is in contact with the cable and moves relatively to the cable to loosen the stains on the insulating layer and clean the outer peripheral surface of the insulating layer. Specifically, the brush 5 can move along the extension direction of the cable to brush the cable, or the brush 5 is stationary and the cable is in contact with the brush 5. As the cable moves, the stains on the cable are cleaned by the brush 5.

[0046] An optional implementation of this embodiment is as follows: the first cleaning roller 21 can be rotatably arranged on the bracket, and the linear speed of the outer surface of the first cleaning roller 21 is different from the transmission speed of the cable. Specifically, the tangential direction of the brush 5 on the first cleaning roller 21 and the cable should be opposite to the rotation direction of the first cleaning roller 21, so as to improve the cleaning effect of the cable.

[0047] An optional implementation of this embodiment is as follows: the second cleaning mechanism 3 includes a plurality of second cleaning rollers 31, such as Figure 1-2 As shown, multiple second cleaning rollers 31 are mounted on a bracket, and multiple second cleaning rollers 31 are arranged on both sides of the cable along the radial direction of the cable, that is, the axial direction of the second cleaning roller 31 is perpendicular to the extension direction of the cable, and the radial direction of the cable is perpendicular to the axial direction of the second cleaning roller 31. Multiple second cleaning rollers 31 perpendicular to the radial directions of different cables can increase the contact area between the second cleaning roller 31 and the insulation layer of the cable, so that the second cleaning roller 31 can better clean the stains on the insulation layer; Figure 2 、 Figure 4-5As shown, in this embodiment, at least two second cleaning rollers 31 are provided perpendicular to the same radial direction of the cable, that is, the two second cleaning rollers 31 are arranged on both sides of the cable, and the two second cleaning rollers 31 are perpendicular to the same radial direction of the cable, so that when the second cleaning rollers 31 clean the cable, two second cleaning rollers 31 can be installed in the same circumferential direction of the cable to reduce the mutual interference of the second cleaning rollers 31 in the same circumferential direction; further, the distance between the two second cleaning rollers 31 perpendicular to the same radial direction of the cable is adjustable, so as to be suitable for cables of different sizes, or to adjust the pressure between the second cleaning rollers 31 and the cable, thereby changing the cleaning effect of the cable; as shown in FIG. Figure 2 As shown, there can be multiple second cleaning rollers 31 perpendicular to the same radial direction of the cable, and the multiple second cleaning rollers 31 are arranged along the extension direction of the cable; more preferably, the distances between the multiple second cleaning rollers 31 perpendicular to the same radial direction of the cable are different, so that the pressures of different second cleaning rollers 31 on the cable are different, thereby improving the cleaning effect of the second cleaning roller 31 on the cable; more preferably, multiple second cleaning rollers 31 are provided along the extension direction of the cable, and the angles between the multiple second cleaning rollers 31 and the cable are different. In this way, as the cable moves, the multiple second cleaning rollers 31 increase the contact area with the cable in the same circumferential direction, thereby improving the cleaning effect of the cable; the first cleaning roller 21 and the second cleaning roller 31 are both connected to the drive motor, and the drive motor rotates to drive the first cleaning roller 21 and the second cleaning roller 31 to rotate. Specifically, the drive motor can be connected to the first cleaning roller 21 and the second cleaning roller 31 through a chain drive, a belt drive or a gear drive, as shown in FIG. Figure 2 As shown, the first cleaning rollers 21 in the embodiment of the present invention are connected by a chain or gear transmission, and the second cleaning rollers 31 are connected by a chain or gear transmission, and the drive motor is respectively connected to any one of the first cleaning rollers 21 and the second cleaning rollers 31 through a chain transmission.

[0048] An optional implementation of this embodiment is as follows: sponges 6 are provided on the roller wall surfaces of multiple second cleaning rollers 31. When the cable abuts the sponge 6, the sponge 6 can clean the surface of the insulation layer of the cable, and the dust or oil stains on the insulation layer of the cable can be adsorbed by the sponge 6 in the holes of the sponge 6, thereby cleaning the cable. The sponge 6 can also be made of cotton, cloth, etc. The second cleaning roller 31 is rotatably mounted on the bracket, and the linear speed of the outer wall of the sponge 6 is different from the transmission speed of the cable. Specifically, the tangential direction of the sponge 6 on the second cleaning roller 31 at the point where the cable abuts should be opposite to the rotation direction of the second cleaning roller 31, that is, the linear speed direction of the sponge 6 at the point where the cable abuts is opposite to the moving direction of the cable. In this way, the relative movement speed of the sponge 6 and the cable is increased, which helps to clean the stains on the surface of the cable more thoroughly, making the stains easier to clean, thereby improving the cleaning effect of the cable.

[0049] An optional implementation of this embodiment is as follows: the graphics processing mechanism includes a plurality of industrial cameras, and the plurality of industrial cameras are evenly distributed around the extension direction of the cable to facilitate circumferential detection of the cable. Optionally, when the industrial camera detects defects in the cable, the industrial camera first photographs the cable to obtain a graphic of the cable, and then pre-processes the captured image to improve the accuracy of subsequent analysis, and then extracts features related to the defect, such as color, shape, texture, etc., and then uses image processing and analysis algorithms to perform defect detection on the product image based on the extracted features, classify and judge the detected defects, and determine whether they meet the product quality standards. Finally, the detection results are output and the defects of the cable are recorded. The specific steps and methods for detecting defects using industrial cameras are common knowledge of those skilled in the art, so they will not be described in further detail.

[0050] An optional implementation of this embodiment is as follows: Figure 10-11 As shown, the transmission mechanism 4 includes a winder 41 and a winding wheel 42, wherein the winder 41 is located downstream of the image processing mechanism, and the winder 41 is used to collect the cable and drive the cable to move to transmit the cable; the winding wheel 42 is installed on the winder 41 and is connected to the winder 41 by transmission. Optionally, the winder 41 is provided with a drive motor, and the drive motor and the winder 41 are connected to the winding wheel 42 by gears or chain transmission. The drive motor rotates, thereby driving the winding wheel 42 to rotate, and the winder 41 drives the winding wheel 42 to rotate, so as to wind the cable around the winding wheel 42, so as to collect the cleaned cable; as shown Figure 11 As shown, a fixing seat 9 is provided on the winding wheel 42 , and the fixing seat 9 is used to press one end of the cable between the fixing seat 9 and the winding wheel 42 to fix one end of the cable, thereby making it easier to wind the cable onto the winding wheel 42 .

[0051] An optional implementation of this embodiment is as follows: Figure 11 As shown, the diameter of the winding wheel 42 gradually decreases from one end to the other end. When the cable is wound, the cable is wound around the winding wheel 42 close to the side with a larger diameter of the winding wheel 42, so that the cable can be pushed from the end with a larger diameter of the winding wheel 42 to the other end, thereby making it easier to separate the cable from the winding wheel 42.

[0052] An optional implementation of this embodiment is as follows: In order to facilitate the guidance of the cable, the cable surface cleaning and defect detection device further includes a guide member 7, such as Figure 1-2As shown in Figure 8, the guide member 7 is installed on the bracket. Specifically, the guide member 7 includes a guide column 71, a guide wheel 72 and a guide rod 73, wherein there are two guide columns 71, which are installed on the bracket and are located on the side of the first cleaning roller 21 away from the second cleaning roller 31. The axial directions of the two guide columns 71 are perpendicular to the transmission direction of the cable, and the cable moves toward the first cleaning roller 21 through the two guide columns 71. The guide column 71 is used to guide the cable to the brush 5 and the sponge 6 to reduce the movement of the cable outside the brush 5, thereby reducing the cleaning effect of the cable. In order to facilitate the adjustment of the cleaning position of the cable at the brush 5 and the sponge 6, the guide column 71 can be moved horizontally in a direction perpendicular to the cable transmission direction; there are two guide wheels 72, which are both installed on the bracket and located at the industrial Between the camera and the transmission mechanism 4, the axes of the two guide wheels 72 are perpendicular to the transmission direction of the cable and are arranged in the horizontal direction. The circumferential outer walls of the two guide wheels 72 are provided with grooves. A channel for passing the cable is formed between the grooves of the two guide wheels 72. The guide wheels 72 are used to guide the cleaned cable to the winding wheel 42. In order to reduce the friction between the cable and the guide wheel 72, the guide wheel 72 is rotatably installed on the bracket. In order to facilitate the adjustment of the guide position of the guide wheel 72, the guide wheel 72 can be moved axially; the guide rod 73 is installed on the bracket and is located below the cable. The cross-section of the guide rod 73 is circular, and the diameter of the guide rod 73 gradually increases from the middle of the guide rod 73 to both ends. The guide rod 73 is used to receive the cable and guide the cable to the middle of the guide rod 73, thereby reducing the movement of the cable to the outside of the two sides of the bracket.

[0053] In summary, the cable surface cleaning and defect detection device provided by the present invention uses a fixing seat 9 to press one end of the cable between the fixing seat 9 and the winding wheel 42 when inspecting the cables of locomotive vehicles. The winding wheel 42 rotates, thereby driving the cable to move, and at the same time, the cable is wound on the winding wheel 42. Under the transmission of the transmission mechanism 4, the cable first passes through, and the guide column 71 is used to guide the cable to the brush 5 and the sponge 6 to reduce the cable from moving outside the brush 5. Then, it passes through multiple first cleaning rollers 21. The brush 5 on the first cleaning roller 21 abuts against the cable and moves relatively to loosen the stains on the insulating layer and clean the outer peripheral surface of the insulating layer. Then, the cable passes through multiple second cleaning rollers 31 The sponge 6 on the second cleaning roller 31 contacts and moves relative to the cable, and the dust or oil stains on the cable insulation layer can be absorbed by the sponge 6 in the holes of the sponge 6, thereby cleaning the cable again. As the transmission mechanism 4 continues to transport, the cable moves to the industrial camera, and the industrial camera takes pictures of the cable for detection and records the defect position of the insulation layer. Then, it is guided by the guide wheel 72 and wound on the winding wheel 42. The guide rod 73 is used to receive the cable and guide the cable to the middle of the guide rod 73, thereby reducing the movement of the cable to the outside of the two sides of the bracket. When the cable needs to be separated from the winding wheel 42, the cable is pushed from the end with a larger diameter of the winding wheel 42 to the other end, so as to loosen the cable. Therefore, the cable surface cleaning and defect detection device further reduces the stains attached to the cable by cleaning the cable multiple times, thereby reducing the impact of the stains on the recognition of the detection unit 8, thereby making the detection unit 8 better at recognizing the surface of the cable, improving the recognition effect of the detection unit 8 on cable surface defects, reducing the detection unit 8's misjudgment or missed judgment of the cable defect position, and further improving the operation safety of locomotive vehicles.
