The cable is clamped and fixed by the fixing assembly, and the cable end is clamped between the two conductive plates by the pressure roller assembly and the pressure plate assembly, and the pressure is measured by the pressure tester.

[0003] Charging pile cables are usually scattered on the ground and may be run over by vehicles. Therefore, it is necessary to test the voltage resistance of the cables to avoid the risk of cable damage. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a charging pile cable withstand voltage testing device that can detect the withstand voltage of cables, allowing staff to observe the withstand voltage of cables and ensure the production quality of cables.

[0005] This utility model discloses a charging pile cable withstand voltage testing device, comprising a testing platform, two support plates, two base plates, multiple support ribs, a conveying assembly, a testing assembly, and a support assembly. Support plates are connected to the left and right ends of the bottom of the testing platform, and base plates are connected to the bottom of the support plates. Multiple support ribs are installed between the base plates and the side walls of the support plates. A positioning groove is provided on the top of the testing platform, and conveying assemblies are installed at the left and right ends of the positioning groove. The testing assembly is installed on the top of the testing platform, and the support assembly is installed on the side walls of the left and right ends of the testing platform. The support plates and base plates support the bottom of the device to ensure stability during use. The conveying assembly moves the sampled cable within the positioning groove on the top of the testing platform, and the testing assembly tests the withstand voltage of the cable. Operators can observe the withstand voltage of the cable to ensure the production quality of the cable.

[0006] Preferably, the conveying assembly includes two conveying shafts, two conveying wheels, two reducers, a dual-output motor, and a pressing component. Conveying grooves are provided at both ends of the testing platform. The two conveying shafts are rotatably mounted within these grooves, with conveying wheels installed on them. The input ends of the conveying shafts pass through the rear wall of the testing platform and connect to the input ends of the reducers. The dual-output motors are installed in the middle of the rear side wall of the testing platform, with their left and right output ends connected to the input ends of the reducers. Starting the dual-output motors drives the conveying shafts to rotate via the reducers, which in turn drives the conveying wheels to rotate, allowing the sampled cable to move within the positioning groove at the top of the testing platform, facilitating comprehensive testing of the cable.

[0007] Preferably, the pressing and conveying component includes two mounting frames, two T-shaped slide bars, two clamping frames, two pressing wheels, two springs, and two sets of limiting slide bars. The mounting frames are fixedly installed on the left and right ends of the top of the testing table. T-shaped slide bars are slidably installed on the top of the mounting frames, and clamping frames are installed at the bottom of the T-shaped slide bars. Pressing wheels are rotatably installed on the lower part of the clamping frames, and the pressing wheels are located above the conveying wheels. The pressing wheels are fitted onto the top of the T-shaped slide bars. The bottom of the springs is connected to the top of the mounting frames. Limiting slide bars are symmetrically installed at the front and rear ends of the clamping frames, and the limiting slide bars are slidably installed on the top of the mounting frames. By pulling the T-shaped slide bars on the mounting frames with the springs, the pressing wheels are pressed against the cable, preventing the cable from slipping between the cable and the conveying wheels during conveying. When the clamping frames move, they drive the limiting slide bars to slide on the mounting frames, increasing structural strength and ensuring stability.

[0008] Preferably, the testing assembly includes two sets of first cylinders, two sets of pressure blocks, a fixed arm, a second cylinder, and an upper pressure block. The two sets of first cylinders are located on the left and right sides of the top of the testing platform, respectively. The first cylinders are symmetrically arranged about the positioning groove. The extension end of the first cylinder is equipped with a pressure block. The fixed arm is installed in the middle of the top of the testing platform. The top of the fixed arm is equipped with a second cylinder, and the extension end of the bottom of the second cylinder is equipped with an upper pressure block. When the first cylinder is activated, it pushes the two pressure blocks closer together to squeeze the front and rear sides of the cable. At the same time, the second cylinder is activated to move the upper pressure block downward to fully press the cable and test its withstand voltage. The operator can observe the withstand voltage of the cable to ensure the production quality of the cable.

[0009] Preferably, it also includes two sets of fixed plates, two sets of guide rods, two connecting plates, and two sliding rods. A fixed plate is fixedly installed on the first cylinder, and the bottom of the fixed plate is connected to the top of the testing platform. Guide rods are slidably installed on the left and right ends of the fixed plate and are connected to the outer wall of the pressure block. Connecting plates are bolted to the front and rear ends of the upper pressure block, and sliding rods are connected to the outer wall of the connecting plates. The sliding rods are slidably installed on the fixed arm. When the first cylinder pushes the pressure block to move, the pressure block drives the guide rods to slide on the fixed plate to support and guide it. At the same time, when the second cylinder pushes the upper pressure block downward, it drives the sliding rods to slide on the fixed arm to enhance the connection strength and ensure stability.

[0010] Preferably, the support assembly includes two conveying brackets and two conveying rollers. The two conveying brackets are respectively installed in the conveying trough, and the conveying rollers are rotatably mounted on the conveying brackets. When the cable moves, it is supported by the conveying brackets and the conveying rollers. At the same time, when the cable moves, it drives the conveying rollers to rotate on the conveying brackets to prevent wear.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the bottom of the equipment is supported by the support plate and the base plate to ensure stability during use; the sampling cable is moved in the positioning groove on the top of the testing table by the conveying component; the cable's pressure resistance is tested by the testing component; and the staff can observe the cable's pressure resistance to ensure the production quality of the cable.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5As shown, support plates 2 are connected to the left and right ends of the bottom of the testing platform 1. A base plate 3 is connected to the bottom of the support plate 2. Multiple support ribs 4 are installed between the base plate 3 and the side wall of the support plate 2. A positioning groove is opened on the top of the testing platform 1. Conveying grooves are opened on the left and right ends of the testing platform 1. Two conveying shafts 5 are rotatably installed in the conveying grooves. Conveying wheels 6 are installed on the conveying shafts 5. The input end of the conveying shaft 5 passes through the rear wall of the testing platform 1 and is connected to the input end of the reducer 7. A dual-output motor 8 is installed in the middle of the rear side wall of the testing platform 1. The left and right output ends of the dual-output motor 8 are connected to the input ends of the reducer 7. The mounting frame 9 is fixedly installed on the left and right ends of the top of the testing platform 1. A T-shaped slide rod 10 is slidably installed on the top of the mounting frame 9. A clamping frame 11 is installed at the bottom of the T-shaped slide rod 10. A pressure feeding wheel 12 is rotatably installed on the lower part of the clamping frame 11. The pressure feeding wheel 12 is located above the conveying wheel 6 and is fitted on the top of the T-shaped slide rod 10. The bottom of the spring 13 is connected to the top of the mounting frame 9. Limiting slide rods 14 are symmetrically installed at the front and rear ends of the 11. The limiting slide rods 14 are slidably installed on the top of the mounting frame 9. Two sets of first cylinders 15 are located on the left and right sides of the top of the testing table 1 respectively. The first cylinders 15 are symmetrically arranged about the positioning groove. A pressure block 17 is installed on the telescopic end of the first cylinder 15. A fixed arm 19 is installed in the middle of the top of the testing table 1. A second cylinder 21 is installed on the top of the fixed arm 19. An upper pressure block 22 is installed on the telescopic end of the bottom of the second cylinder 21. A fixed plate 16 is fixedly installed on the first cylinder 15. The bottom of the fixed plate 16 is connected to the top of the testing table 1. Guide rods 18 are slidably installed on the left and right ends of the fixed plate 16. The guide rods 18 are connected to the outer wall of the pressure block 17. A connecting plate 23 is installed on the front and rear ends of the upper pressure block 22 by bolts. A sliding rod 24 is connected to the outer wall of the connecting plate 23. The sliding rod 24 is slidably installed on the fixed arm 19. Two conveying brackets 25 are installed in the conveying groove respectively. A conveying roller 26 is rotatably installed on the conveying bracket 25.

[0020] The dual-output motor 8, driven by the reducer 7, rotates the conveyor shaft 5, which in turn rotates the conveyor wheel 6. This causes the sampled cable to move within the positioning slot at the top of the testing platform 1, facilitating comprehensive cable testing. A spring 13 pulls the T-shaped slide bar 10 to slide on the mounting frame 9, pressing the pressure roller 12 against the cable to prevent slippage between the cable and the conveyor wheel 6 during transport. As the pressing frame 11 moves, it causes the limiting slide bar 14 to slide on the mounting frame 9, increasing structural strength and ensuring stability. The cable is supported by the conveyor bracket 25 and the conveyor roller 26 as it moves, simultaneously causing the conveyor roller 26 to move on the conveyor bracket. Rotating the upper cylinder 25 prevents wear. The first cylinder 15 is activated to push the two pressure blocks 17 closer together to squeeze the front and rear sides of the cable. At the same time, the second cylinder 21 is activated to move the upper pressure block 22 downward to fully press the cable and test its pressure resistance. The staff can observe the pressure resistance of the cable to ensure the production quality of the cable. When the first cylinder 15 pushes the pressure block 17 to move, the pressure block 17 drives the guide rod 18 to slide on the fixed plate 16 to support and guide it. At the same time, when the second cylinder 21 pushes the upper pressure block 22 downward, it drives the sliding rod 24 to slide on the fixed arm 19 to enhance the connection strength and ensure stability.

[0021] like Figures 1 to 5 As shown, this utility model discloses a charging pile cable withstand voltage testing device. During operation, a dual-output motor 8 is started, which drives a conveyor shaft 5 to rotate via a reducer 7. The conveyor shaft 5 drives a conveyor wheel 6 to rotate, causing the sampled cable to move within the positioning groove on the top of the testing platform 1. As the cable moves, it is supported by a conveyor bracket 25 and a conveyor roller 26. Simultaneously, the cable's movement causes the conveyor roller 26 to rotate on the conveyor bracket 25, preventing wear. A spring 13 pulls a T-shaped sliding rod 10 to slide on a mounting frame 9, causing the pressure roller 12 to press firmly against the cable, preventing slippage between the cable and the conveyor wheel 6 during transport. The first cylinder 15 is activated to push two pressure blocks 17 closer together to compress the front and rear sides of the cable. Simultaneously, the second cylinder 21 is activated to move the upper pressure block 22 downwards, providing comprehensive pressure on the cable and testing its withstand voltage. Operators can observe the cable's withstand voltage level.
