Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cable testing, and in particular to a cable insulation testing device. Background Art
[0002] Cables are used to transmit electrical energy or signals. When transmitting electrical energy, cables are divided into high-voltage cables and low-voltage cables. Regardless of whether it is a high-voltage cable or a low-voltage cable, the electrical energy transmitted in it will cause harm to the human body. Therefore, during the processing and production of cables, a layer of insulating sheath will be put on the outer surface of the cable. On the one hand, it can prevent electric shock caused by human or animal contact, and on the other hand, it can protect the core wire inside the cable. In order to ensure the insulation effect of the cable, after the cable is produced, it needs to be tested for insulation to verify whether the cable can be put into use. The current cable insulation test mainly measures the insulation resistance of the cable;
[0003] With respect to the above-mentioned related technologies, the inventor believes that in cable testing, insulation testing is a key step to ensure the normal operation of the cable. Traditional cable insulation testing devices usually perform tests at fixed positions and cannot adjust the test height and angle according to actual needs.
[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content
[0005] In order to solve the problem that insulation testing is a key step to ensure the normal operation of the cable during cable testing, traditional cable insulation testing devices usually perform testing in a fixed position and are unable to adjust the test height and angle according to actual needs, the present application provides a cable insulation testing device.
[0006] The present application provides a cable insulation test device that adopts the following technical solution:
[0007] A cable insulation testing device comprises a base plate, the upper end of which is fixedly connected to a vertical plate, a rectangular cavity is formed in the vertical plate, an opening is provided on the vertical plate, two threaded rods are rotatably connected between the upper and lower inner walls of the rectangular cavity, the lower ends of the two threaded rods are fixedly connected to transmission wheels, the two transmission wheels are connected by transmission belts, a first motor is installed on the upper end of the vertical plate, and an adjustment mechanism for the cable insulation testing device is provided on the vertical plate.
[0008] Preferably, the adjustment mechanism includes a movable plate threadedly connected to two threaded rods, the output shaft end of the first motor extends into the rectangular cavity and is fixedly connected to the upper end of the threaded rod on the left, and a horizontal plate is provided on the front side of the movable plate.
[0009] Preferably, two fixed plates are fixedly connected to the front side of the horizontal plate, a second motor is installed on the upper end of the upper fixed plate, a bidirectional threaded rod is rotatably connected between the two fixed plates, and the output shaft end of the second motor extends to the lower end of the upper fixed plate and is fixedly connected to the upper end of the bidirectional threaded rod.
[0010] Preferably, two limit plates are symmetrically threadedly connected on the bidirectional threaded rod, two guide rods are symmetrically fixedly connected between the two fixed plates, and the two guide rods both pass through the two limit plates and are slidably connected to the two limit plates.
[0011] Preferably, a third motor is installed on the rear side of the movable plate, and the output shaft end of the third motor extends to the front side of the movable plate and is fixedly connected to the rear side of the transverse plate.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. After the first motor is started, the threaded rod on the left side rotates. Since the two threaded rods are connected by a transmission belt, the two threaded rods rotate synchronously, so that the movable plate drives the fixed cable to move up or down to adjust the height. It is worth mentioning here that the third motor can be started according to the actual situation, so that the entire movable plate drives the fixed cable to rotate with the output shaft of the third motor as the axis to achieve angle adjustment. The overall adjustment method is more flexible;
[0014] 2. After the second motor is started, the bidirectional threaded rod will rotate. When the bidirectional threaded rod rotates, the two limit plates will move relative to each other to fix the cable. The staff can then test the cable, so that the device can adapt to more cables of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The following is combined with Figure 1-3 This application is described in further detail.
[0020] The present application embodiment discloses a cable insulation testing device. Figure 1 A cable insulation testing device comprises a bottom plate 8, a vertical plate 1 is fixedly connected to the upper end of the bottom plate 8, a rectangular cavity 2 is opened in the vertical plate 1, an opening 3 is arranged on the vertical plate 1, two threaded rods 4 are rotatably connected between the upper and lower inner walls of the rectangular cavity 2, the lower ends of the two threaded rods 4 are fixedly connected to transmission wheels, the two transmission wheels are connected through a transmission belt 7, a first motor 5 is installed on the upper end of the vertical plate 1, and an adjustment mechanism for the cable insulation testing device is arranged on the vertical plate 1.
[0021] Reference Figure 1 The adjustment mechanism includes a movable plate 6 threadedly connected to two threaded rods 4. The end of the output shaft of the first motor 5 extends into the rectangular cavity 2 and is fixedly connected to the upper end of the threaded rod 4 on the left. A horizontal plate 9 is arranged on the front side of the movable plate 6.
[0022] After the first motor 5 is started, the threaded rod 4 on the left side rotates. Since the two threaded rods 4 are connected by the transmission belt 7, the two threaded rods 4 rotate synchronously, so that the movable plate 6 drives the fixed cable to move up or down for height adjustment.
[0023] Reference Figure 1-3 Two fixing plates 11 are fixedly connected to the front side of the horizontal plate 9, and a second motor 10 is installed on the upper end of the fixing plate 11 above. A bidirectional threaded rod 12 is rotatably connected between the two fixing plates 11. The output shaft end of the second motor 10 extends to the lower end of the fixing plate 11 above and is fixedly connected to the upper end of the bidirectional threaded rod 12. Two limit plates 13 are symmetrically threadedly connected on the bidirectional threaded rod 12. Two guide rods 14 are symmetrically fixedly connected between the two fixing plates 11. The two guide rods 14 both penetrate the two limit plates 13 and are slidably connected to the two limit plates 13.
[0024] When the second motor 10 is started, the bidirectional threaded rod 12 will rotate. When the bidirectional threaded rod 12 rotates, the two limit plates 13 will move relative to each other to fix the cable. The staff can then test the cable, so that the device can adapt to more cables of different sizes.
[0025] Reference Figure 1-2 A third motor 15 is installed on the rear side of the movable plate 6 , and the output shaft end of the third motor 15 extends to the front side of the movable plate 6 and is fixedly connected to the rear side of the transverse plate 9 .
[0026] The third motor 15 is started, so that the entire movable plate 6 drives the fixed cable to rotate around the output shaft of the third motor 15 to achieve angle adjustment.
[0027] The implementation principle of a cable insulation test device in the embodiment of the present application is as follows: when in use, the cable to be tested is placed between the two limit plates 13, and then the second motor 10 is started. After the second motor 10 is started, the bidirectional threaded rod 12 is rotated. When the bidirectional threaded rod 12 rotates, the two limit plates 13 are relatively moved to fix the cable. Then the staff can test the cable, so that the device can adapt to more cables of different sizes.
[0028] During the test, the first motor 5 can be started. After the first motor 5 is started, the threaded rod 4 on the left side rotates. Since the two threaded rods 4 are connected by the transmission belt 7, the two threaded rods 4 rotate synchronously, so that the movable plate 6 drives the fixed cable to move up or down for height adjustment. It is worth mentioning here that the third motor 15 can be started according to actual conditions, so that the entire horizontal plate 9 drives the fixed cable to rotate around the output shaft of the third motor 15 to achieve angle adjustment. The overall adjustment method is more flexible.
