Description

Technical Field

[0001] The present application relates to the technical field of cable detection, and in particular to a non-destructive flaw detection device for cables. Background Art

[0002] Cables are an important industry in my country. They are a large category of electrical products used in the fields of power transmission, information transmission, and lighting. They are essential basic equipment for manufacturing various motors, electrical appliances, instruments, and other fields to achieve electromagnetic energy conversion. Among them, it is very important to perform flaw detection on cables before use.

[0003] The nondestructive testing device for flaw detection of power cables mentioned in the existing Chinese public patent (authorization announcement number: CN219391961U) can facilitate the sliding connection between the support plate and the placement groove through the cooperation of the sliding groove and the sliding block, so as to facilitate the installation of the detection device. The support plate is limited by the cooperation of the movable card plate and the card plate groove to avoid the shaking of the support plate as much as possible, which affects the detection result and improves the connection stability. The cooperation of the hydraulic cylinder and the hydraulic rod is convenient to adjust the height of the detector, which is suitable for the detection of cables of different diameters. The protective cover is provided to facilitate the protection of the control panel and has a dustproof effect. The corrugated pipe is used to protect the hydraulic column and improve the service life. The wire roller is provided to guide and support the transmission of the cable. The wire roller is easy to install and disassemble through the cooperation of the mounting plate and the No. 1 bolt, which is convenient for replacement according to the cable diameter and enhances the practicality. The cover plate is cooperated with the No. 2 bolt to facilitate the removal and replacement of the unwinding roller and improve the detection efficiency.

[0004] In the existing practice of flaw detection on cables, the cables are usually placed on a reel, and then one end of the cable is moved to the bottom of the detection device for detection. After the detection is completed, the cable is reeled up again for collection and use. However, in actual use, the length of the cable is generally long, so the detection time is long. After placing the cable on the reel, the staff may do other work, which may result in the cable being completed without paying attention to the completion of the detection work in time, thereby interrupting the processing and reducing work efficiency. Utility Model Content

[0005] The purpose of this application is to solve the problem that after placing the cable on the reel, the staff may do other work, which may lead to failure to pay attention to the completion of the inspection work in time after the cable is completed. This application provides a non-destructive flaw detection device for cables.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A nondestructive flaw detection device for cables comprises a workbench, wherein the top four corners of the workbench are fixedly connected with supporting legs, the two sides of the top of the workbench are fixedly connected with mounting plates, one side of the mounting plate is rotatably connected with a roller, the top of the workbench is fixedly connected with a detection platform, one side of the detection platform is fixedly connected with a control panel, the top of the detection platform is fixedly connected with a hydraulic cylinder, the output end of the hydraulic cylinder passes through the detection platform and is fixedly connected with a detection device, the control panel is electrically connected to the detection device, an interference mechanism is provided at the bottom of the roller, a cross block is fixedly connected with one side of the mounting plate, the bottom of the cross block is fixedly connected with a sensor, the sensor is electrically connected to the control panel, a connecting block is provided above the workbench, the connecting block is slidably connected to the mounting plate, the top of the connecting block is fixedly connected with a sensing block, the sensing block is adapted to the sensor, a buzzer is fixedly connected with the top of the workbench, and the buzzer is electrically connected to the control panel.

Next, the motor is started to allow the cable on the roller to slowly pass through the detection device for detection. When the cable gradually becomes thinner, the connecting block moves upward to drive the sensing block upward. When the cable detection is completed, the sensing block moves to the bottom of the sensor, and the sensor transmits a signal to the control panel, which stops the transportation of the cable and then starts the buzzer to alarm, thereby reminding the staff to take out and replace the cable, thereby improving the continuity of the production line and reminding the staff to make replacements.

[0016] By adopting the above technical solution, the position of the cable is limited by the conductor roller, so that the cable can be accurately detected by the detection device, thereby improving the accuracy of the detection.

[0019] Furthermore, an auxiliary rod is fixedly connected to the top of the detection device, the top end of the auxiliary rod passes through the detection platform and is fixedly connected to a limit block, and the auxiliary rod is slidably connected to the detection platform.

[0020] By adopting the above technical solution, the auxiliary rod is slidably connected to the detection platform, and the auxiliary rod provides an additional support point for the detection device, so that the detection device is more stable when moving.

[0021] In summary, the present application includes at least one of the following beneficial effects:

[0022] 1. In this application, when the cable gradually becomes thinner, the contact table moves upward, and the contact table drives the connecting block upward, and the upward movement of the connecting block drives the sensing block upward. When the cable detection is completed, the sensing block moves to the bottom of the sensor, and the sensor transmits the signal to the control panel, and the control panel stops the transportation of the cable, and then starts the buzzer to alarm, thereby reminding the staff to take out and replace the cable, thereby improving the continuity of the production line and ensuring the continuous operation of the production line.

[0023] 2. In the present application, when testing the cable, the cable will contact the contact roller, causing the telescopic rod to contract. When the cable on the roller gradually becomes less, the elastic potential energy of the spring begins to be slowly released. As the pressure decreases, the spring begins to gradually return to its original state and releases the stored elastic potential energy, causing the contact roller to be subjected to a reverse force. When the cable slowly becomes thinner, the contact roller can still firmly contact the cable, thereby achieving stable contact with the cable and smooth testing process.

[0030] The following is combined with Figures 1 to 4 This application is described in further detail.

[0031] The embodiment of the present application discloses a nondestructive flaw detection device for cables.

[0032] Reference Figure 1 , Figure 2and Figure 4 A nondestructive flaw detection device for a cable comprises a workbench 1, wherein the four corners of the top of the workbench 1 are fixedly connected with supporting legs 2, the two sides of the top of the workbench 1 are fixedly connected with mounting plates 3, one side of the mounting plate 3 is rotatably connected with a reel 4, the top of the workbench 1 is fixedly connected with a detection table 7, one side of the detection table 7 is fixedly connected with a control panel 10, the top of the detection table 7 is fixedly connected with a hydraulic cylinder 8, the output end of the hydraulic cylinder 8 passes through the detection table 7 and is fixedly connected with a detection device 9, the control panel 10 is electrically connected with the detection device 9, a resistance mechanism is arranged at the bottom of the reel 4, a horizontal block 16 is fixedly connected with one side of the mounting plate 3, a sensor 17 is fixedly connected with the bottom of the horizontal block 16, and the sensor 17 is electrically connected with the control panel 10, a connecting block 18 is arranged above the workbench 1, the connecting block 18 is slidably connected with the mounting plate 3, a sensor block 19 is fixedly connected with the top of the connecting block 18, and the sensor block 19 is adapted to the sensor 17, a buzzer 21 is fixedly connected with the top of the workbench 1, and the buzzer 21 is electrically connected with the control panel 10.

[0033] When performing cable flaw detection, the rolled cable must first be placed on the reel 4 on one side, and then the staff will pass the end of the cable through the bottom of the detection device 9 and place it on the reel 4 on the other side. Next, start the motor so that the cable on the reel 4 slowly passes through the detection device 9 for detection. During this process, the detection device 9 will monitor the cable throughout the entire process and collect various information inside the cable in real time. If a problematic cable is encountered, the detection device 9 will send a signal to the control panel 10, and the control panel 10 will immediately stop the transportation of the cable, and then work through the resistance mechanism to sound an alarm. When the cable is being tested, the resistance mechanism will resist the bottom of the cable, which can ensure that the cable remains stable during the detection process and reduce inaccurate detection results caused by cable sliding. When the cable gradually becomes thinner, the resistance platform 11 moves upward, and the resistance platform 11 will drive the connecting block 18 upward, and the upward movement of the connecting block 18 drives the sensing block 19 upward. When the cable detection is completed, the sensing block 19 moves to the bottom of the sensor 17, and the sensor 17 transmits a signal to the control panel 10, and the control panel 10 stops the transportation of the cable, and then starts the buzzer 21 to sound an alarm, thereby reminding the staff to take out and replace the cable, thereby improving the continuity of the production line and ensuring the continuity of the production line.

[0034] Reference Figure 2 and Figure 3The conflict mechanism includes a conflict platform 11 arranged at the bottom of the unwinding roller 4, the conflict platform 11 is fixedly connected to the connecting block 18, a telescopic rod 14 is fixedly connected to the bottom of the conflict platform 11, and the bottom end of the telescopic rod 14 is fixedly connected to the workbench 1, and rotating blocks 12 are fixedly connected to the top of the conflict platform 11 on both sides, and a conflict roller 13 is rotatably connected between the rotating blocks 12 on both sides, and the conflict roller 13 conflicts with the cable on the winding roller 4, and an alarm component is arranged on one side of the mounting plate 3.

[0035] The outer surface of the telescopic rod 14 is sleeved with a spring 15 , the top of the spring 15 is fixedly connected to the bottom of the abutment platform 11 , and the bottom end of the spring 15 is fixedly connected to the bottom end of the abutment platform 11 .

[0036] When the cable is tested, the cable will hit the resistance roller 13, and the resistance roller 13 will transfer the pressure to the rotating block 12, and the rotating block 12 will transfer the pressure to the resistance platform 11. After the resistance platform 11 is subjected to the force, the telescopic rod 14 will be contracted, and after the telescopic rod 14 is contracted, the spring 15 will be contracted. After the spring 15 is contracted, elastic potential energy is generated. When the cable on the winding roller 4 gradually becomes less, the elastic potential energy of the spring 15 begins to be slowly released. As the pressure decreases, the spring 15 begins to gradually return to its original state and releases the stored elastic potential energy, so that the resistance roller 13 will be subjected to a reverse force. When the cable gradually becomes thinner, the resistance roller 13 can still firmly contact the cable, so as to achieve stable contact with the cable and smooth detection process.

[0037] Reference Figure 2 and Figure 4 A slide groove 20 is provided on one side of the mounting plate 3 close to the connecting block 18 , and a slider is fixedly connected to one end of the connecting block 18 . The slider is adapted to the slide groove 20 , and the slider is slidably connected to the slide groove 20 .

[0038] When the connecting block 18 moves, it is slidably connected with the sliding groove 20 through the slider, thereby providing a guiding function for the connecting block 18, so that the connecting block 18 is guaranteed to be on the correct track when moving.

[0039] Reference Figure 3 A conductor block 25 is fixedly connected to both sides of the top of the workbench 1. An empty slot is opened inside the conductor block 25. A conductor roller 26 is arranged inside the empty slot. The conductor roller 26 is rotatably connected to the inner wall of the empty slot.

[0040] When the cable moves to below the detection device 9, the position of the cable is limited by the wire roller 26, so that the cable can be accurately detected by the detection device 9, thereby improving the accuracy of the detection.

[0041] Reference Figure 1 , Figure 2 and Figure 4The top of the workbench 1 is fixedly connected to an electric push rod 22, which is electrically connected to the control panel 10. The top of the electric push rod 22 is fixedly connected to a rotating seat 23, which is rotatably connected to the roller 4.

[0042] When the cable needs to be removed, the electric push rod 22 is started through the control panel 10, so that the electric push rod 22 drives the rotating seat 23 to separate from the winding roller 4. At this time, the cable can be removed and a new cable is placed on the winding roller 4. At this time, the electric push rod 22 is continued to be started, so that the rotating seat 23 is firmly against the winding roller 4.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The top of the detection device 9 is fixedly connected with an auxiliary rod 24, the top of the auxiliary rod 24 passes through the detection platform 7 and is fixedly connected to the limiting block, and the auxiliary rod 24 is slidably connected to the detection platform 7.

[0044] When the detection device 9 moves, the detection device 9 drives the auxiliary rod 24 to slide inside the detection platform 7. The auxiliary rod 24 is slidably connected to the detection platform 7. The auxiliary rod 24 provides an additional support point for the detection device 9, making the detection device 9 more stable when moving.

[0045] Working principle: When conducting cable flaw detection, first, the rolled cable needs to be placed on the reel 4 on one side, and then the staff passes the end of the cable through the bottom of the detection device 9 and places it on the reel 4 on the other side. Next, the motor is started so that the cable on the reel 4 slowly passes through the detection device 9 for detection. When the detection device 9 moves downward for detection, the detection device 9 drives the auxiliary rod 24 to slide inside the detection table 7, and is slidably connected to the detection table 7 through the auxiliary rod 24. The auxiliary rod 24 provides an additional support point for the detection device 9, making the detection device 9 more stable when moving. When the cable is detected, the cable will contact the contact roller 13. As the cable gradually becomes less, the spring 15 begins to gradually return to its original state and releases the stored elastic potential energy, so that the contact roller 13 will be subjected to a reverse force, so that when the cable slowly becomes thinner, the contact roller 13 can still firmly contact the cable, which can achieve stable contact with the cable and smooth progress of the detection process.

[0046] When the cable gradually becomes thinner, the abutment table 11 moves upward, and the abutment table 11 drives the connecting block 18 upward, and the connecting block 18 moves upward to drive the sensing block 19 upward. When the cable detection is completed, the sensing block 19 moves to the bottom of the sensor 17, and the sensor 17 transmits the signal to the control panel 10. The control panel 10 stops the transportation of the cable and then starts the buzzer 21 to alarm, thereby reminding the staff to take out and replace the cable, thereby improving the continuity of the production line and ensuring the continuous operation of the production line. When the cable needs to be removed, the electric push rod 22 is started through the control panel 10, so that the electric push rod 22 drives the rotating seat 23 to disengage from the winding roller 4, and the cable can be removed at this time.
