AI Technical Summary
In the prior art, when the non-metallic material protective layer of the cable passes through the detection area of the detection probe, the conveying element of the conveying device cannot perform a complete search inspection, resulting in an increase in the detection process and a longer time. At the same time, the conveying element is only transmitted by contact, making it difficult to avoid unnecessary axial rotation of the cable, resulting in inaccurate detection results.
A surface detection device applied to non-metallic materials is designed, including an intermediate frame plate, four intermediate limit rotors, two sets of limit detection mechanisms and detection probes. By setting the installation angle of the side long frame plate to deflect 90 degrees, switching between the detection position and the limit guide position is achieved, ensuring that the cable does not rotate unnecessarily during transmission, so that surface defect detection at all positions is completed in one inspection process.
It effectively avoids unnecessary axial rotation of the cable during transmission, reduces detection processes and time, improves detection efficiency and accuracy, and ensures that the surface defects of the non-metallic material protective layer can be completely detected in one inspection.

Description
Technical Field
[0001] The utility model relates to the technical field of defect detection of non-metallic material protective layers on the outer surface of cables, and in particular to a surface detection device applied to non-metallic materials. Background Art
[0002] Cable is a main transmission element in an electric energy or signal transmission device, usually composed of several or several groups of wires. Most cables are installed outdoors through brackets. Due to the harsh outdoor environment, cables are easily blown by strong winds and caused wear or scratches by external forces, affecting the transmission of electric energy or signals. Therefore, the outer surface of the cable is generally covered with an insulating protective layer. The outer material of the insulating protective layer is generally made of non-metallic material, which needs to have the characteristics of corrosion resistance, strong heat conductivity and anti-penetration, so as to protect the internal cable through the external non-metallic material protective layer.
[0003] After the cable is coated with a non-metallic material protective layer, it needs to undergo surface defect detection again before it can be put into use to ensure that there are no surface defects such as cracks or fissures on the surface of the non-metallic material protective layer. The main detection device is a surface detection device used for the non-metallic material protective layer. The cable is continuously conveyed by a conveying device, and surface flaw detection and subsequent surface defect analysis are completed under the detection of the detection probe. However, due to the existence of the conveying device, when the non-metallic material protective layer of the cable passes through the detection area of the detection probe, there is a part that cannot be detected due to the obstruction of the conveying element of the conveying device. It is necessary to adjust the contact position between the clamping conveying element and the non-metallic material protective layer again, and then pass the part that was not detected last time through the detection area of the detection probe to completely complete the surface defect detection of the non-metallic material protective layer on the outer surface of the cable, which increases the overall detection process, that is, increases the detection time. On the other hand, the conveying element only relies on contact to transmit the cable, and it is difficult to avoid unnecessary axial rotation of the cable, so that some cracks or cracks are squeezed due to rotation, thereby causing surface obstruction and unable to complete accurate detection, and ultimately leading to inaccurate detection results.
[0004] Therefore, it is necessary to invent a surface detection device for non-metallic materials to solve the above problems. Utility Model Content

It is necessary to adjust the contact position between the clamping conveying element and the non-metallic material protective layer again, and then pass the part that was not detected last time through the detection area of the detection probe to completely complete the surface defect detection of the non-metallic material protective layer on the outer surface of the cable, which increases the overall detection process, that is, increases the detection time. On the other hand, the conveying element only relies on contact to transmit the cable, and it is difficult to avoid unnecessary axial rotation of the cable, so that some cracks or cracks are squeezed due to rotation, thereby causing surface obstruction and unable to complete accurate detection, and ultimately leading to inaccurate detection results.

[0009] As a preferred solution of the utility model, a side wall of the mounting plate located on the side long frame plate is provided with multiple second mounting columns, and a second socket is provided at the other end of the second mounting column. The multiple side limiting wheels can be removably and rotatably installed in the corresponding second sockets.
[0010] As a preferred solution of the utility model, mounting seats are installed at both ends of a side wall of the plug plate located in the side long frame plate, and the multiple detection probes are detachably installed in the corresponding mounting seats.
[0011] As a preferred solution of the utility model, a U-shaped card plate can be detachably installed at one end of the two side long frame plates away from each other, and a limiting sleeve is detachably embedded in the center of the U-shaped card plate, and the non-metallic material protective layer on the outer surface of the cable is inserted into the limiting sleeve.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0014] In the utility model, when the cable with a non-metallic material protective layer passes through the detection device, it enters from the side long frame plate on one side, passes through the middle frame plate, and then passes out through the side long frame plate on the other side. Since all the components in the two sets of limit detection mechanisms are the same, only the installation positions of the two side long frame plates on both sides of the middle frame plate are deflected 90 degrees, that is, the positions of the side limit rotating wheel and the detection probe in the left side long frame plate are swapped with the positions of the side limit rotating wheel and the detection probe in the right side long frame plate, so that the detection position in the left side long frame plate is in the limit guide position in the right side long frame plate, and the limit guide position in the left side long frame plate is in the detection position in the right side long frame plate, thereby completing the detection of non-metallic materials in all positions in the detection process from entry to transmission once. Surface defect detection of the material protective layer can effectively avoid re-inspection, reduce the inspection process and shorten the inspection time. At the same time, in the inspection process from one entry to transmission, multiple rotating side limit wheels on both sides contact the surface of the non-metallic protective layer to limit it to prevent rotation, and when the inspection position and the limit guide position are switched through the middle frame plate, the middle limit wheels rotating in multiple positions will also contact the surface of the non-metallic protective layer to limit it to prevent rotation. Finally, under the multi-position limit guide of the side limit wheels and the middle limit wheels, unnecessary axial rotation of the cable during the transmission process is effectively avoided, ensuring that the limit detection mechanism on the left and the limit detection mechanism on the right can complete surface defect detection at all positions at one time, thereby improving inspection efficiency and inspection accuracy.

[0023] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.
[0024] The utility model provides Figure 1-Figure 6 A surface detection device for non-metallic materials shown in the figure comprises an internally hollow middle frame plate 1 and four middle limit rotating wheels 5 rotatably arranged on the four side walls inside the middle frame plate 1.

[0025] A first mounting column 3 is provided in the middle of the four side walls inside the middle frame plate 1, and a first clamping seat 4 is provided at the other end of the first mounting column 3. Multiple intermediate limiting rotating wheels 5 can be removably and rotatably installed in the corresponding first clamping seats 4. The first mounting column 3 and the first clamping seat 4 can limit the position of the intermediate limiting rotating wheels 5 in the middle frame plate 1, ensuring that the four intermediate limiting rotating wheels 5 are in contact with the non-metallic material protective layer and are limited to prevent rotation.
[0026] A plurality of second mounting columns 13 are provided on one side wall of the mounting plate 10 located on the side long frame plate 6, a second clamping seat 14 is provided at the other end of the second mounting column 13, and a plurality of side limiting rotating wheels 15 are respectively detachably and rotatably mounted in the corresponding second clamping seats 14. The second mounting columns 13 and the second clamping seat 14 can limit the position of the side limiting rotating wheels 15 in the side long frame plate 6, ensuring that the plurality of side limiting rotating wheels 15 are in contact with the non-metallic material protective layer and are limited to prevent rotation.
[0027] Mounting seats 8 are installed at both ends of a side wall of the plug board 7 located in the side long frame plate 6. Multiple detection probes 9 can be detachably installed in the corresponding mounting seats 8. The mounting seats 8 can provide installation positions for the detection probes 9 on the plug board 7 and are distributed at both ends of the plug board 7, so as to perform double detection at the entry end and the exit end respectively, thereby improving the detection contrast.
[0028] A U-shaped card plate 16 is detachably installed at one end of the two side long frame plates 6 that are away from each other. A limiting sleeve 17 is detachably embedded in the center of the U-shaped card plate 16. The non-metallic material protective layer on the outer surface of the cable is passed through the limiting sleeve 17. The two limiting sleeves 17 on both sides can respectively serve as the entry end and the exit end of the whole. From the entry end to the exit end, it is a detection process.
[0029] The four corners of the left and right side walls of the middle frame plate 1 are provided with first mounting studs 2, and the symmetrical ends of the side long frame plate 6 are connected with first mounting seats 11 that can be detachably connected to the first mounting studs 2. The first mounting stud 2 is threadedly sleeved with a first nut 19 that can lock the position of the first mounting seat 11 and the first mounting stud 2. The symmetrical side walls of the side long frame plate 6 are provided with mounting grooves, and the two mounting plates 10 can be detachably installed in the corresponding mounting grooves respectively. The outside of the symmetrical side walls of the side long frame plate 6 is provided with second mounting studs 12, and the two ends of the mounting plate 10 are adapted to the positions Both are connected with a second mounting socket 18 which can be detachably clamped to the second mounting stud 12. The second mounting stud 12 is threadedly sleeved with a second nut 20 which can lock the position of the second mounting socket 18 and the second mounting stud 12. The first mounting sockets 11 are respectively located at the diagonals of the side long frame plates 6. In the actual installation process, the two side long frame plates 6 on both sides are only installed and connected with the first mounting sockets 11 and the first mounting studs 2 at different positions, so that the two side long frame plates 6 are deflected 90 degrees, thereby completing the switching of the detection position and the limit guide position.
[0030] In the utility model, when the cable with a non-metallic material protective layer passes through the detection device, it enters from the side long frame plate 6 on one side, passes through the middle frame plate 1, and then passes out through the side long frame plate 6 on the other side. Since all the components in the two sets of limit detection mechanisms are the same, only the installation positions of the two side long frame plates 6 on both sides of the middle frame plate 1 are deflected 90 degrees, that is, the positions of the side limit rotating wheel 15 and the detection probe 9 in the left side long frame plate 6 are swapped with the positions of the side limit rotating wheel 15 and the detection probe 9 in the right side long frame plate 6, so that the detection position in the left side long frame plate 6 is in the limit guide position in the right side long frame plate 6, and the limit guide position in the left side long frame plate 6 is in the detection position in the right side long frame plate 6, so that all positions are completed in the detection process from entry to transmission once. Surface defect detection of the non-metallic material protective layer can effectively avoid re-inspection, reduce the inspection process and shorten the inspection time. At the same time, in the inspection process from one entry to transmission, multiple rotating side limit wheels 15 on both sides contact the surface of the non-metallic protective layer to limit it to prevent rotation, and when the inspection position and the limit guide position are switched through the middle frame plate 1, the middle limit wheel 5 rotating in multiple positions will also contact the surface of the non-metallic protective layer to limit it to prevent rotation. Finally, under the multi-position limit guidance of the side limit wheel 15 and the middle limit wheel 5, unnecessary axial rotation of the cable during the transmission process is effectively avoided, ensuring that the limit detection mechanism on the left and the limit detection mechanism on the right can complete the surface defect detection of all positions at one time, thereby improving the inspection efficiency and inspection accuracy.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
