Description

Technical Field

[0001] This utility model relates to the field of cable testing, and in particular to a device for detecting cracks on the surface of cables. Background Technology

[0002] A cable surface crack detection device is a specialized device used for automatic or semi-automatic detection of cable sheath cracks, damage, or other surface defects. It typically combines optical, image processing, or sensor technologies to scan the cable surface in real time, identify anomalies, and mark or record the location of defects.

[0003] Existing cable surface crack detection devices typically use a single marker to mark the outer surface of the cable. However, they cannot be customized with different colored markers depending on the color of the cable's outer sheath. Furthermore, when the marker color is similar to the cable's outer surface color, the marking location becomes difficult to observe.

[0004] Therefore, given that existing cable surface crack detection devices use single-color markers for marking and cannot switch markers according to the cable sheath color, there is an urgent need to design a new type of cable surface crack detection device. Utility Model Content

[0005] To overcome the problem that existing cable surface crack detection devices use single-color markers for marking and cannot switch markers according to the color of the cable sheath.

[0006] The technical solution of this utility model is as follows: a cable surface crack detection device, including a workbench; it also includes a U-shaped mounting base, a fixing block, a damping sleeve, a marker pen, a transmission shaft, a first driven gear, a second drive motor, and a first driving gear. The detection instrument body is installed in the middle of the upper surface of the workbench. A drive assembly is set on the left side of the front surface of the detection instrument body. A U-shaped mounting base is installed at the rear end of the drive assembly. The fixing block is rotatably connected to the left and right sides of the inner surface of the U-shaped mounting base. Damping sleeves are set on all four sides of the outer surface of the fixing block. A marker pen is inserted into the inside of the damping sleeve. A transmission shaft is installed on the right side surface of the fixing block. The right end of the transmission shaft passes through the right side wall of the U-shaped mounting base and is connected to the first driven gear. A second drive motor is set on the right side surface of the U-shaped mounting base in front of the transmission shaft. The output end of the second drive motor is connected to the first driving gear. The first driving gear meshes with the first driven gear.

[0007] Preferably, by setting a second drive motor, its output end will drive the first drive gear to rotate during operation. When the first drive gear rotates, it can drive the first driven gear meshing with it to rotate synchronously, thereby causing the transmission shaft to drive the fixed block to rotate. This allows for switching between different colored markers, avoiding the problem that the marker color is similar to the cable's outer surface color, making it difficult to observe the marked points. This solves the problem that existing cable surface crack detection devices typically use a single marker to mark the cable's outer surface, making it impossible to change to different colored markers according to the different colors of the cable's outer sheath. When the marker color is similar to the cable's outer surface color, the marked position becomes difficult to observe.

[0008] Preferably, the drive assembly includes a mounting frame, a first drive motor, a lead screw, and a movable seat; the mounting frame is located on the left side of the front surface of the detector body, the first drive motor is mounted on the top surface of the mounting frame, the output end of the first drive motor passes through the top of the mounting frame and is connected to one end of the lead screw, the other end of the lead screw is rotatably connected to the bottom of the inner surface of the mounting frame, and the movable seat is threaded through the outer surface of the lead screw.

[0009] Preferably, the drive assembly also includes an electric push rod; the electric push rod is connected to the rear surface of the movable seat, and the telescopic end of the electric push rod is connected to the U-shaped mounting base.

[0010] Preferably, a bearing is embedded in the middle of the right side surface of the detector body, and an installation tube is connected to the inner surface of the bearing, with a sponge adhered to the inner surface of the installation tube.

[0011] Preferably, a second driven gear is installed on the right side of the outer surface of the mounting tube, and a third drive motor is installed on the right side of the detector body located behind the mounting tube. The output end of the third drive motor is connected to a second driving gear, and the second driving gear meshes with the second driven gear.

[0012] Preferably, the bottom surface of the workbench is equipped with an equipment cabinet, and the bottom corners of the equipment cabinet are equipped with casters.

[0013] Preferably, the top surface of the detector body is provided with a top cover, and the upper surface of the top cover is provided with a heat dissipation fan.

[0014] The beneficial effects of this utility model are:

[0015] 1. By configuring a second drive motor, during the marking operation, its output shaft will drive the first drive gear to rotate. The first drive gear, through meshing with the first driven gear, drives the first driven gear to rotate synchronously, thereby causing the transmission shaft to drive the fixed block to rotate. This rotation mechanism enables the rapid switching of different colored markers, avoiding the problem that the marking points are difficult to identify when the marker color is similar to the cable sheath color. This solves the problem that existing cable surface crack detection devices usually use one marker to mark the outer surface of the cable, and cannot change to different colored markers according to the different colors of the cable sheath. When the color of the marker is similar to the color of the cable outer surface, the marking position becomes difficult to observe. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a cable surface crack detection device, including a workbench 1; it also includes a U-shaped mounting base 4, a fixing block 5, a damping sleeve 6, a marker pen 7, a transmission shaft 8, a first driven gear 9, a second drive motor 10, and a first driving gear 11. The detection instrument body 2 is mounted in the middle of the upper surface of the workbench 1. A drive assembly is located on the left side of the front surface of the detection instrument body 2. The U-shaped mounting base 4 is mounted at the rear end of the drive assembly. The fixing blocks 5 are rotatably connected to the left and right sides of the inner surface of the U-shaped mounting base 4. Damping sleeves 6 are provided on all four sides of the outer surface of the fixing block 5. A marker pen 7 is inserted into the inside of the damping sleeve 6. The transmission shaft 8 is mounted on the right side surface of the fixing block 5, and the right end of the transmission shaft 8 passes through the U-shaped mounting base 4. The right side wall of the mounting base 4 is connected to a first driven gear 9. The right side surface of the U-shaped mounting base 4, located in front of the transmission shaft 8, is provided with a second drive motor 10. The output end of the second drive motor 10 is connected to a first driving gear 11. The first driving gear 11 meshes with the first driven gear 9. By setting the second drive motor 10, its output end will drive the first driving gear 11 to rotate during operation. When the first driving gear 11 rotates, it can drive the first driven gear 9, which meshes with it, to rotate synchronously. This causes the transmission shaft 8 to drive the fixed block 5 to rotate, thereby switching between different colored marker pens 7. This avoids the problem that the color of the marker pen 7 is similar to the color of the outer surface of the cable when marking, making it difficult to observe the marked points.

[0023] Please see Figures 1-4In this embodiment, the drive assembly includes a mounting frame 31, a first drive motor 32, a lead screw 33, and a movable seat 34. The mounting frame 31 is located on the left side of the front surface of the detector body 2. The first drive motor 32 is mounted on the top surface of the mounting frame 31. The output end of the first drive motor 32 passes through the top of the mounting frame 31 and is connected to one end of the lead screw 33. The other end of the lead screw 33 is rotatably connected to the bottom of the inner surface of the mounting frame 31. The movable seat 34 is threadedly connected to the outer surface of the lead screw 33. By setting the first drive motor 32, its output end will drive the lead screw 33 to rotate during operation. When the lead screw 33 rotates, it can drive the movable seat 34, which is threadedly engaged with it, to move up and down, thereby driving the marker pen 7 on the rear side to move upwards. The downward movement and drive assembly also include an electric push rod 35; the rear surface of the moving base 34 is connected to the electric push rod 35, and the telescopic end of the electric push rod 35 is connected to the U-shaped mounting base 4. By setting the electric push rod 35, during operation, its telescopic end can drive the tip of the marker pen 7 to contact the outer surface of the cable, thereby completing the marking of the cable under the cooperation of the lead screw 33. A bearing 12 is embedded in the middle of the right side surface of the detector body 2. The inner surface of the bearing 12 is connected to the mounting tube 13, and the inner surface of the mounting tube 13 is adhered with a sponge 14. By setting the bearing 12, the mounting tube 13 can rotate. When the mounting tube 13 rotates, it can drive the sponge 14 to wipe the outer surface of the cable, reducing the impact of dust on the detection accuracy.

[0024] Please see Figures 1-4 In this embodiment, a second driven gear 15 is installed on the right side of the outer surface of the mounting tube 13. A third drive motor 16 is installed on the right side of the detector body 2, located behind the mounting tube 13. The output end of the third drive motor 16 is connected to a second drive gear 17, which meshes with the second driven gear 15. By setting the third drive motor 16, its output end will drive the second drive gear 17 to rotate during operation. When the second drive gear 17 rotates, it can drive the second driven gear 15, which meshes with it, to rotate, thereby driving the mounting tube 13 to rotate automatically. An equipment cabinet 18 is set on the bottom surface of the workbench 1. Universal wheels 19 are set at the corners of the bottom surface of the equipment cabinet 18. By setting the universal wheels 19, the device can be moved easily, improving flexibility. A top cover 20 is set on the top surface of the detector body 2. A cooling fan 21 is set on the upper surface of the top cover 20. By setting the cooling fan 21, the detector body 2 can be cooled, avoiding the problem of overheating and aging of the equipment due to long-term operation.

[0025] During operation, the first drive motor 32 drives the lead screw 33 to rotate. The rotation of the lead screw 33 causes the threaded movable seat 34 to move up and down, thereby moving the marker pen 7 at the rear. An electric push rod 35 extends and retracts during operation, causing the tip of the marker pen 7 to contact the outer surface of the cable. With the assistance of the lead screw 33, the cable is marked. A bearing 12 allows the mounting tube 13 to rotate, and this rotation causes the lead screw 34 to move up and down. The cotton 14 wipes the outer surface of the cable to reduce the impact of dust on the detection accuracy. By setting a third drive motor 16, its output end will drive the second drive gear 17 to rotate during operation. When the second drive gear 17 rotates, it can drive the second driven gear 15 meshing with it to rotate, thereby driving the mounting tube 13 to rotate automatically. By setting universal wheels 19, the entire device can be moved easily, improving flexibility. By setting a cooling fan 21, the detector body 2 can be cooled to avoid the problem of overheating and aging of the equipment due to long-term operation.

[0026] Through the above steps, by configuring the second drive motor 10, during the marking operation, its output shaft will drive the first drive gear 11 to rotate. The first drive gear 11, through meshing with the first driven gear 9, drives the first driven gear 9 to rotate synchronously, thereby causing the transmission shaft 8 to drive the fixed block 5 to rotate. This rotation mechanism realizes the rapid switching of different colored marker pens 7, avoiding the problem that the marking points are difficult to identify when the color of the marker pen 7 is similar to the color of the cable sheath. This solves the problem that existing cable surface crack detection devices usually use one marker pen 7 to mark the outer surface of the cable, and cannot change to different colored marker pens 7 according to the different colors of the cable sheath. When the color of the marker pen 7 is similar to the color of the cable outer surface, the marking position becomes difficult to observe.
