Description

Technical Field

[0001] This invention relates to the field of insulation testing technology, and in particular to an insulation testing device for wear-resistant cables. Background Technology

[0002] Cables typically consist of cable cores and an insulating sheath. The conductivity and insulation of cables are crucial for their safe use. During production and use, the cable insulation layer requires rigorous testing to ensure compliance with standards. Before insulation testing, each of the three phases of the cable must be fully discharged using a discharge clamp. Testing requires phase-by-phase operation, with one phase designated as the test phase and the other two grounded. After the test phase is completed, it is fully discharged again using the discharge clamp, and then the next phase is tested, repeating the process for each phase. Therefore, insulation testing requires frequent plugging and unplugging of the three-phase connectors for grounding and discharge, a cumbersome and time-consuming process. Furthermore, the megohmmeter needs to be placed horizontally, requiring leveling adjustments. This process suffers from low automation, low testing efficiency, and potential safety hazards. Summary of the Invention

The wall is equipped with a driving airbag 2062, and a second connecting pipe 2063 is provided between the driving airbag 2062 and the horizontal tube 2051. When the first frame 3031 moves downward, it will drive the pressure plate 2064 to move downward. When the pressure plate 2064 continues to move, it will enter the placement frame 2061 and squeeze the driving airbag 2062. The gas in the driving airbag 2062 will enter the second connecting pipe 2063 under the influence of pressure. The gas will then enter the horizontal tube 2051 and the first connecting pipe 2052 in sequence, and finally enter the reinforcing frame 2053. The gas will push the reinforcing rod 2055 to move outward. The reinforcing rod 2055 will drive the reinforcing plate 2056 to move towards the clamping ring 2042 and finally contact the clamping ring 2042 to achieve the clamping and limiting operation of the clamping ring 2042. When excessive movement occurs, the cooperation of the third spring 2066 and the moving plate 2065 can prevent the joint from being damaged by excessive gas pressure.The guiding component 207 includes a guiding ring 2071 fixedly connected to the top of the platform 1. Multiple fourth springs 2072 are fixedly connected to both sides of the inner wall of the guiding ring 2071. The other end of the fourth spring 2072 is fixedly connected to a limiting plate 2073, which can press the cable down from inside the guiding ring 2071, so that the cable enters into the two limiting plates 2073. Under the action of the fourth spring 2072, the cable is limited. The limiting mechanism 2 can effectively guide the cable to be tested, so that the conductors in the cable are arranged in an orderly manner. During the test, it can be driven by the moving testing mechanism 3 to automatically reinforce the joint, so that the joint will not move during the test, avoiding the instability of the traditional manual connection joint, which can improve the accuracy and efficiency of the test.

[0020] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the moving assembly 303 includes a first frame 3031 fixedly connected to the bottom end of the cylinder 302. A first lead screw 3032 is rotatably connected to the inner wall of the first frame 3031. A first limiting rod 3034 is fixedly connected to the inner wall of the first frame 3031. A first moving block 3035 is threadedly connected to the surface of the first lead screw 3032. A first motor 3033 is fixedly connected to one end of the first frame 3031. One end of the first lead screw 3032 passes through the first frame 3031 and is fixedly connected to the output shaft of the first motor 3033. A second frame 3036 is fixedly connected to the front end of the first moving block 3035. A second lead screw 3037 is rotatably connected to the inner wall of the second frame 3036. A second moving block 3035 is threadedly connected to the surface of the second lead screw 3037. The moving block 30310 has a second motor 3038 fixedly connected to one end of the second frame 3036. The other end of the second lead screw 3037 passes through the second frame 3036 and is fixedly connected to the output shaft of the second motor 3038. A second limiting rod 3039, which is slidably connected to the second moving block 30310, is fixedly connected to the inner wall of the second frame 3036. Two telescopic detection components 304 are respectively disposed at the front end of the second moving block 30310 and the other end of the second frame 3036. The upper end of the pressure plate 2064 is fixedly connected to the first frame 3031. The telescopic detection component 304 includes a fixed cylinder 3041. A fifth spring 3042 is fixedly connected to the inner top wall of the fixed cylinder 3041. A telescopic rod 304 is fixedly connected to the bottom end of the fifth spring 3042. 3. A detection block is provided at the bottom of the telescopic rod 3043. A connecting line 3044 is provided on the surface of the detection block. When detecting adjacent joints, the cylinder 302 is activated, which directly pushes the first frame 3031 and the second frame 3036 downward as a whole. The detection block will contact the joint first. As the cylinder 302 continues to descend, the height of the telescopic rod 3043 remains unchanged, the fifth spring 3042 bends, and the fixed cylinder 3041 continues to move downward, increasing the contact force between the detection block and the joint. When it is necessary to detect adjacent joints at different positions, the first motor 3033 is activated. The first motor 3033 drives the first lead screw 3032 to rotate. Under the action of the first limit rod 3034, the first moving block 3035 will drive the second frame. 3036 moves as a whole, thus moving the two detection blocks together. When non-adjacent joint positions need to be detected, the second motor 3038 is activated, driving the second lead screw 3037 to rotate. Under the action of the second limit rod 3039, the position of the second moving block 30310 changes. At this time, one of the detection blocks and the second frame 3036 are fixedly installed and will not move, thus adjusting the distance between the two detection blocks. After adjustment, the cylinder 302 is used to raise and lower the block to complete the detection operation. The moving detection mechanism 3 can automatically adjust the vertical and horizontal positions of the detection blocks and effectively adjust the distance between the two detection blocks, making it more convenient to detect different joints.No manual operation is required, saving debugging time and improving testing efficiency. The 304 telescopic testing component also possesses a certain degree of flexibility, ensuring better contact between the testing block and the connector, achieving thorough testing without damaging the connector, and improving testing accuracy.

[0021] like Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the horizontal placement mechanism 4 includes a square plate 401 fixedly connected to one side of the platform 1. A liquid storage cylinder 402 is provided at each of the four corners of the top of the square plate 401. A third connecting pipe 403 is provided between adjacent liquid storage cylinders 402. A fixing component 404 is provided at the top of each liquid storage cylinder 402. The interior of each liquid storage cylinder 402 is filled with a medium liquid component. A limit component 405 is provided on the fixing component 404. The fixing component 404 includes a round rod fixedly connected to the inner bottom wall of the liquid storage cylinder 402. Multiple liquid storage cylinders 402... An I-shaped plate 4041 is fixedly connected between 02 and 02. An air pump 4042 is installed at the top of the I-shaped plate 4041. An I-shaped tube 4043 is installed on the air pump 4042. A suspension ring 4044 is sleeved on the surface of the round rod. An installation ring 4045 is fixedly connected to the top of the suspension ring 4044. The top of the installation ring 4045 passes through the liquid storage cylinder 402 and is fixedly connected to a horizontal plate 40411. A placement pad 40412 is installed at the top of the horizontal plate 40411. A circular tube is installed on the surface of the installation ring 4045. A fourth connecting pipe 4047 is provided between the annular pipe 4046 and the I-beam pipe 4043. A ring-shaped cylindrical tube 4048 is fixedly connected to the surface of the mounting ring 4045. The cylindrical tube 4048 and the annular pipe 4046 are connected. A sixth spring 4049 is fixedly connected to one end of the inner wall of the cylindrical tube 4048. A fixing rod 40410 is fixedly connected to the other end of the sixth spring 4049. The other end of the fixing rod 40410 passes through the cylindrical tube 4048. The liquid medium inside the storage cylinder 402... Under the action of the third connecting pipe 403, the liquid level will be at the same height, and the suspension ring 4044 will always be on the liquid surface due to buoyancy. When the suspension ring 4044 is stable, the air pump 4042 will be started. The air pump 4042 will first deliver gas into the I-beam pipe 4043, and then enter the cylinder 4048 through the fourth connecting pipe 4047. The gas pushes the fixing rod 40410 to move outward. The spherical part at the other end of the fixing rod 40410 contacts the inner wall of the liquid storage cylinder 402 to achieve the fixing operation.The limiting assembly 405 includes a limiting frame 4051 fixedly connected to the I-shaped plate 4041. A seventh spring 4052 is fixedly connected to the inner top wall of the limiting frame 4051. A horizontal plate 4053 is fixedly connected to the bottom end of the seventh spring 4052. Contact plates 4054 are fixedly connected to both ends of the horizontal plate 4053. A pull rod 4055 is fixedly connected to the top end of the horizontal plate 4053. The top end of the pull rod 4055 extends through the limiting frame 4051. By pulling the pull rod 4055 upward, the seventh spring 4052 bends, and the horizontal plate 4053 moves upward. A megohmmeter is placed between the horizontal plate 4053 and the horizontal plate 40411. After placement, the assembly is released. The pull rod 4055, using the elastic force of the seventh spring 4052, drives the horizontal plate 4053 and the contact plate 4054 to move downwards, limiting the megohmmeter. The horizontal placement mechanism 4 can quickly adjust the horizontal state, so that the horizontal plate 40411 can be in a horizontal state, making the megohmmeter more accurate during testing, thereby improving the accuracy of the test. The required adjustment time is short, saving the time of adjusting the horizontal state. Moreover, the limiting component 405 can effectively limit the megohmmeter, so that the megohmmeter is stably placed on the fixed component 404, reducing the shaking of the megohmmeter during use. The automatic limiting eliminates the need for excessive operation, reducing the difficulty of operating the megohmmeter.

[0022] In use, the present invention selects the appropriate megohmmeter for the cable to be tested, and adjusts the horizontal placement mechanism 4. Under the action of the third connecting pipe 403, the liquid level inside the storage cylinder 402 will be at the same height. The suspension ring 4044 will remain on the liquid surface due to buoyancy. When the suspension ring 4044 is stable, the air pump 4042 is started. The air pump 4042 first delivers gas to the I-beam pipe 4043, then through the fourth connecting pipe 4047 into the cylinder 4048. The gas pushes the fixing rod 40410 outward. The spherical part at the other end of the fixing rod 40410 contacts the inner wall of the storage cylinder 402 to achieve fixation. Pulling upward with the pull rod 4055 causes the seventh spring 4052 to bend, and the horizontal plate 4053... Move upwards to place the megohmmeter between the horizontal plate 4053 and the horizontal plate 40411. After placement, release the pull rod 4055. Using the elastic force of the seventh spring 4052, move the horizontal plate 4053 and the contact plate 4054 downwards to limit the megohmmeter. After limiting, press the cable downwards from the guide ring 2071, so that the cable enters the two limiting plates 2073. Under the action of the fourth spring 2072, the cable is limited. Use the plastic clip 202 to initially limit the cable branch. After limiting, place the cable joint above the placement plate 2044. Push the cable into the placement groove 203. Under the action of the guide plate 2043, the cable will enter between the two clamping rings 2042. Under the action of spring 2041, the cable itself is clamped and limited. When detecting adjacent joints, cylinder 302 is activated, which directly pushes the first frame 3031 and the second frame 3036 downwards as a whole. The detection block will contact the joint first. As cylinder 302 continues to descend, the height of telescopic rod 3043 remains unchanged, the fifth spring 3042 bends, and the fixed cylinder 3041 continues to move downwards, increasing the contact force between the detection block and the joint. During this process, the downward movement of the first frame 3031 will drive the pressure plate 2064 downwards. As the pressure plate 2064 continues to move, it will enter the placement frame 2061 and compress the driving airbag 2062. The gas in the driving airbag 2062 will enter the placement frame 2061 under pressure. Gas enters the second connecting pipe 2063 sequentially into the horizontal pipe 2051 and the first connecting pipe 2052, finally entering the reinforcing frame 2053. The gas pushes the reinforcing rod 2055 outward, which in turn moves the reinforcing plate 2056 towards the clamping ring 2042, eventually contacting it to achieve clamping and limiting of the clamping ring 2042. In case of excessive movement, the cooperation of the third spring 2066 and the moving plate 2065 prevents excessive gas pressure from damaging the connector. After the detection block contacts the connector, a rotating megohmmeter is used for testing. When testing adjacent connectors at different positions is required, the first motor 3033 is started, driving the first lead screw 3032 to rotate. Under the action of the first limiting rod 3034...The first moving block 3035 drives the second frame 3036 to move as a whole, thus realizing the overall movement of the two detection blocks. When it is necessary to detect the position of non-adjacent joints, the second motor 3038 is started. The second motor 3038 drives the second lead screw 3037 to rotate. Under the action of the second limit rod 3039, the position of the second moving block 30310 will change. At this time, one of the detection blocks and the second frame 3036 are fixedly installed and will not move, thus realizing the adjustment of the distance between the two detection blocks.
