Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable performance detection, in particular to a drag chain cable performance detection device and method. BACKGROUND

[0002] The drag chain cable needs to withstand repeated bending, friction, stretching and other influences for a long time, and its core requirement is to resist repeated bending. Therefore, mechanical performance detection needs to simulate the use environment and the dynamic stress in actual use to detect the mechanical performance and service life, thereby ensuring electrical safety.

[0003] CN119064164A discloses a tensile resistance detection device for a high-flexibility drag chain cable. The detection device applies an extreme tensile force to the drag chain cable under heating, vibration and bending environments, simulates the detection environment, and detects whether the conductor and the insulating outer skin of the drag chain cable are damaged under the corresponding scene.

[0004] However, in a dusty environment, the surface of the drag chain cable is sticky with dust after being left for a certain period of time, which has a certain impact on the structure when starting. When detecting the impact of the drag chain cable on the cable when starting in different concentrations of dusty environments, the cable needs to be left for a long time, which seriously affects the detection efficiency.

[0019] To better achieve the objectives of this invention, this invention also provides a method for testing the performance of drag chain cables, comprising the following steps:

[0020] Step 1: Place multiple cable chains in a natural dusty environment and let them stand for two hours and six hours respectively, and observe the dust adhering to the surface of the cable chains; then create dusty environments of different concentrations, and let the cable chains stand for one minute in the dusty environments of different concentrations, and select a dust concentration that is consistent with the dust adhering to the cable chains after standing in the natural dusty environment for two hours and six hours.

[0021] Step 2: Install the cable chain on the operating simulation mechanism inside the sealed chamber. Connect the fixed end of the cable chain to the testing mechanism, but do not connect the moving end of the cable chain to the testing mechanism. Create dusty environments of different concentrations inside the sealed chamber using different dusty environment creation components and air supply components. Make the amount of dust adhering to the cable chain after one minute of standing still consistent with the amount of dust adhering to the cable chain after two hours and six hours of standing still in a natural dusty environment.

[0022] Step 3: Two sets of operating simulation mechanisms drive the drag chain cable inside the sealed chamber to alternately remain stationary and move; during this process, the appearance of the drag chain cable is detected by a high-definition camera inside the sealed chamber;

[0023] Step 4: After wear appears on the drag chain cable, record the number of times the drag chain cable is stationary and the number of times it is moved. After the drag chain cable has been moved a certain number of times, inspect the appearance of the drag chain cable again with a high-definition camera. At the same time, connect the moving end of the drag chain cable through a testing mechanism and test the electrical performance of the drag chain cable.

[0024] Compared with the prior art, the advantages of this invention are as follows: 1. The drag chain cable is installed on the running simulation mechanism in the sealed chamber, and the fixed end of the drag chain cable is electrically connected to the testing mechanism, while the moving end of the drag chain cable is not electrically connected to the testing mechanism; thereby facilitating the testing of the electrical performance of the drag chain cable after the test, and avoiding interference from moving lines other than the drag chain cable to the test results.

[0025] 2. By using different dusty environment manufacturing components and air supply components to create dusty environments of varying concentrations within the sealed chamber, the amount of dust adhering to the top of the cable chain after one minute of rest is consistent with the dust adhering conditions after two and six hours of rest in a natural dusty environment. This allows for a short-term simulation of the state of the cable chain under natural dusty conditions after a certain period of rest, facilitating subsequent testing of the impact of resting time on the mechanical properties of the cable chain in a dusty environment and improving overall testing efficiency. Two sets of operating simulation mechanisms alternately move and rest the cable chain within the sealed chamber, ensuring sufficient resting time for the cable chain and further enhancing testing efficiency.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The terms "left," "right," "front," "rear," "up," and "down" mentioned in the following description are oriented according to the perspective of a front view.

[0039] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A drag chain cable performance testing device includes a test chamber 1, a running simulation mechanism 3, and a testing mechanism 4;

[0040] The door 11 of the test chamber 1 is located on the front and rear sides of the test chamber 1, and a dusty environment simulation mechanism 2 is installed on the test chamber 1;

[0041] like Figure 2 and Figure 3 As shown, the dusty environment simulation mechanism 2 includes a sealed partition plate 21, a dusty environment manufacturing component 22, an air supply component 23, a reversing structure 24, and a self-cleaning filter component 25. The sealed partition plate 21 is fixedly installed in the middle of the test chamber 1, and the interior of the test chamber 1 is divided into two sealed chambers 211 by the sealed partition plate 21. Two sets of dusty environment manufacturing components 22 and air supply components 23 are installed on the test chamber 1. The reversing structure 24 is installed on the air supply component 23. The self-cleaning filter component 25 is installed on the dusty environment manufacturing component 22.

[0042] The sealed chamber 211 is equipped with two sets of operation simulation mechanisms 3 for moving the drag chain cable 5; the operation simulation mechanisms 3 in the same sealed chamber 211 are not connected.

[0043] Multiple high-definition cameras for inspecting the appearance of the drag chain cable 5 are fixedly installed inside the sealed chamber 211, and a testing mechanism 4 for inspecting the performance of the drag chain cable 5 is installed inside the sealed chamber 211.

[0044] In this embodiment, when the drag chain cable performance testing equipment is working normally, multiple drag chain cables 5 are placed in a natural dusty environment and left to stand for two hours and six hours respectively, and the dust adhering to the surface of the drag chain cables 5 is observed; then, dusty environments of different concentrations are created, and the drag chain cables 5 are left to stand for one minute in the dusty environments of different concentrations, and the dust concentrations that are consistent with the dust adhering conditions on the drag chain cables 5 and the dust adhering conditions of the drag chain cables 5 after standing in the natural dusty environment for two hours and six hours are selected respectively.

[0045] The cable chain 5 is installed on the operating simulation mechanism 3 inside the sealed chamber 211. The fixed end of the cable chain 5 is electrically connected to the testing mechanism 4, while the moving end of the cable chain 5 is not electrically connected to the testing mechanism 4. This facilitates the testing of the electrical performance of the cable chain 5 after the test and avoids interference from moving lines other than the cable chain 5 with the test results. Then, different dusty environments are created in the sealed chamber 211 by different dusty environment creation components 22 and air supply components 23, so that the amount of dust adhering to the upper side of the cable chain 5 after one minute of standing is consistent with the dust adhering condition after two hours and six hours of standing in a natural dusty environment. This facilitates subsequent testing of the impact of the standing time of the cable chain 5 in a dusty environment on its mechanical performance and improves the overall testing efficiency.

[0046] After the drag chain cable 5 has been stationary for one minute, a set of operation simulation mechanisms 3 is started. The set of operation simulation mechanisms 3 drives the drag chain cable 5 located in different sealed chambers 211 to move back and forth. After moving for one minute, the operation simulation mechanism 3 is stopped, and another set of operation simulation mechanisms 3 is started to drive another set of drag chain cables 5 located in different sealed chambers 211 to move back and forth. In this way, the drag chain cables 5 in the sealed chambers 211 are alternately stationary and moved by the two sets of operation simulation mechanisms 3, so as to ensure the stationary time of the drag chain cable 5 and improve the detection efficiency.

[0047] During this process, the appearance of the drag chain cable 5 is detected by a high-definition camera inside the sealed chamber 211. After wear appears on the appearance of the drag chain cable 5, the number of times the drag chain cable 5 is stationary and the number of times it is moved are recorded. Then, after the drag chain cable 5 has been moved a certain number of times, the appearance of the drag chain cable 5 is detected again by a high-definition camera. At the same time, the moving end of the drag chain cable 5 is connected by the detection mechanism 4, and the electrical performance of the drag chain cable 5 is detected.

[0048] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figures 4-6 As shown, the dusty environment manufacturing component 22 includes a first storage tank 221, a second storage tank 222, a stirring motor 223, and a stirring paddle 224. The first storage tank 221 is fixedly installed on the left side of the test chamber 1, and the second storage tank 222 is fixedly installed on the right side of the test chamber 1. A stirring motor 223 is fixedly installed on both the first storage tank 221 and the second storage tank 222, and a stirring paddle 224 is rotatably installed inside both the first storage tank 221 and the second storage tank 222. The output end of the stirring motor 223 passes through the first storage tank 221 and is fixedly connected to the stirring paddle 224.

[0049] The air supply assembly 23 includes a blower 231, a first conveying pipe 232, a first connecting pipe 233, and an air inlet pipe 234. The blower 231 is fixedly installed on the test chamber 1. The air inlet and outlet of the blower 231 are respectively fixedly connected to one end of a first conveying pipe 232. The other end of the first conveying pipe 232 is installed on a reversing structure 24. One end of the first connecting pipe 233 is connected to the reversing structure 24. The other end of the left connecting pipe 233 is fixedly connected to a first storage bin 221, and the other end of the right connecting pipe 233 is fixedly connected to a second storage bin 222. The air inlet pipes 234 are symmetrically distributed on both sides of the test chamber 1. One end of the left air inlet pipe 234 is fixedly connected to a first storage bin 221, and one end of the right air inlet pipe 234 is fixedly connected to a second storage bin 222. The other end of the air inlet pipe 234 is fixedly connected to the test chamber 1. An air inlet 235 is provided on the test chamber 1 aligned with the air inlet pipe 234.

[0050] The interior of the test chamber 1 is connected to the air inlet duct 234 through the air inlet 235; the air inlet duct 234 is connected to the connecting duct 1 233, the conveying duct 1 232, the blower 231, the storage bin 1 221, the storage bin 222 and the reversing structure 24;

[0051] The reversing structure 24 includes a reversing chamber 241, a reversing core 242, a reversing motor 244, a first reversing pipe 245, and a second reversing pipe 246. The reversing chamber 241 is fixedly connected to the first conveying pipe 232 and the first connecting pipe 233. The reversing core 242 is rotatably installed inside the reversing chamber 241, and a central through groove 243 is opened in the middle of the reversing core 242. The reversing motor 244 is fixedly installed at the bottom of the reversing chamber 241, and the output end of the reversing motor 244 is fixedly connected to the reversing core 242. The two ends of the first reversing pipe 245 are fixedly connected to the reversing chambers 241 on both sides respectively. The two ends of the second reversing pipe 246 are fixedly connected to the reversing chambers 241 on both sides respectively. The first reversing pipe 245 and the second reversing pipe 246 are symmetrically distributed.

[0052] The self-cleaning filter assembly 25 includes a mounting block 251, a frame 252, a filter screen 253, guide rods 254, and a vibration assembly. One mounting block 251 is fixedly installed on the side of the storage bin 221 near the connecting pipe 233, and the other mounting block 251 is fixedly installed on the side of the storage bin 222 near the connecting pipe 233. The filter screen 253 is fixedly installed inside the frame 252. Guide rods 254 are evenly fixedly installed in a circumferential array on the frame 252. The guide rods 254 are slidably connected to the mounting block 251. The vibration assembly is installed on the mounting block 251 and the frame 252.

[0053] The vibration assembly includes a spring 255, a magnetic block 256, and an electromagnet 257. The spring 255 is sleeved on the guide rod 254. One end of the spring 255 is fixedly connected to the mounting block 251, and the other end of the spring 255 is fixedly connected to the frame 252. The magnetic blocks 256 are evenly fixedly installed in a circumferential array on the frame 252, and the electromagnets 257 are evenly installed in a circumferential array on the mounting block 251.

[0054] A certain weight of dust is filled into storage bin 1 221 and storage bin 222 respectively, with the amount of dust in storage bin 222 being greater than that in storage bin 1 221. Initially, the two ends of the central through-slot 243 on the reversing core 242 are aligned with conveying pipe 1 232 and connecting pipe 1 233 respectively, and the conveying pipe 1 232 and connecting pipe 1 233 are connected through the central through-slot 243. At this time, the stirring motor 223 on storage bin 222 is started, driving the stirring paddle 224 to rotate. The blower 231 drives the airflow through the right-side conveying pipe 1 232, central through-slot 243, and connecting pipe 1 233 to storage bin 2. After entering 222, the airflow carries dust through the right-side air inlet duct 234 and air inlet 235 into the sealed chamber 211, thereby increasing the concentration of particulate matter in the sealed chamber 211 and creating a dusty environment. The airflow in the sealed chamber 211 carries dust through the left-side air inlet 235 and air inlet duct 234 and flows into the storage bin 221. The dust is then blocked by the filter screen 253 between the storage bin 221 and the left-side connecting duct 233, causing the dust to fall into the storage bin 221. After passing through the filter screen 253, the airflow flows through the connecting duct 233, the central channel 243, and the conveying duct 232 into the blower 231.

[0055] Dust filtered by filter 253 remains in storage bin 221. When filter 253 becomes clogged, electromagnet 257 is activated. Electromagnet 257 attracts magnetic block 256, causing frame 252 and guide rod 254 to move, and spring 255 is compressed. Then electromagnet 257 is deactivated, spring 255 returns to its original position, causing frame 252 to vibrate, thereby shaking off the dust from filter 253 and achieving self-cleaning of filter 253. This effectively prevents dust from entering reversing chamber 241, central channel 243, and blower 231.

[0056] After a certain amount of dust accumulates in storage bin 221, the reversing motor 244 drives the reversing core 242 to rotate 45 degrees. The central through-slot 243 is no longer connected to the conveying pipe 232 and the connecting pipe 233. At this point, gas enters the reversing chamber 241 from the left connecting pipe 233, flows through the reversing pipe 245 to the right reversing chamber 241, then flows through the right conveying pipe 232 to the blower 231; then flows through the left conveying pipe 232 to the left reversing chamber 241, and finally flows through the reversing pipe 246 to the right reversing chamber 241. Inside, the dust flows to the right through the connecting pipe 233 on the right side; at this time, the stirring motor 223 on the right side is turned off, and the stirring motor 223 on the left side is started. The stirring motor 223 drives the stirring paddle 224, which in turn stirs up the dust in the storage bin 221; at this time, the blower 231 drives the airflow through the conveying pipe 232 on the right side, the reversing chamber 241, and the reversing pipe 246 to the reversing chamber 241 on the left side, and then enters the storage bin 221 through the connecting pipe 233 on the left side; thus, the dust in the storage bin 221 enters the test chamber 1 through the air inlet pipe 234 and the air inlet 235 on the left side.

One end of the drag chain cable 5 is electrically connected to the fixed connector 41, and the other end of the drag chain cable 5 is electrically connected to the movable connector 42. The drive motor 36 is started to drive the synchronous transmission shaft 37 to rotate. The synchronous transmission shaft 37 drives the transmission components 35 located in different sealed chambers 211 to rotate, thereby driving the movable mounting plate 33 located in different sealed chambers 211 to move. The movable mounting plate 33 drives one end of the drag chain cable 5 to move, simulating the use state of the drag chain cable 5. During the movement, the movable connector 42 and the connecting connector 47 are not connected, so there is no need to set up a reciprocating movement line other than the drag chain cable 5. During this process, the dust baffle 2 48 blocks the connecting block of the connecting connector 47, and the dust baffle 1 43 blocks the connection port of the movable connector 42. Thus, the connection port of the movable connector 42 and the connecting connector 47 is protected.

[0063] After the drag chain cable 5 is simulated, the connecting cylinder 46 drives the connecting joint 47 to move horizontally. The connecting joint 47 pushes the dustproof baffle 48 to flip, and the torsion spring twists. At the same time, the electromagnet 45 is activated. The electromagnet 45 attracts the magnetic block 44, thereby driving the dustproof baffle 43 to move horizontally, so that the dustproof baffle 43 is disengaged from the interface of the movable joint 42. The connecting cylinder 46 drives the connecting joint 47 to insert into the movable joint 42, so that the drag chain cable 5 is electrically connected to the connecting joint 47 through the movable joint 42. Thus, the drag chain cable 5 is tested by external electrical testing equipment.

[0064] Example 3: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, a method for testing the performance of a drag chain cable includes the following steps:

[0065] Step 1: Place multiple cable chains 5 in a natural dusty environment and leave them for two hours and six hours respectively, and observe the dust adhering to the surface of the cable chains 5; then create dusty environments of different concentrations, and leave the cable chains 5 in the dusty environments of different concentrations for one minute, and select a dust concentration that is consistent with the dust adhering on the cable chains 5 and the dust adhering on the cable chains 5 after leaving them in the natural dusty environment for two hours and six hours respectively.

[0066] Step 2: Install the drag chain cable 5 on the operation simulation mechanism 3 inside the sealed chamber 211. Connect the fixed end of the drag chain cable 5 to the detection mechanism 4, and do not connect the moving end of the drag chain cable 5 to the detection mechanism 4. Create different concentrations of dusty environments in the sealed chamber 211 by using different dusty environment creation components 22 and air supply components 23, so that the amount of dust adhering to the upper side of the drag chain cable 5 after standing for one minute is consistent with the dust adhering situation after standing in a natural dusty environment for two hours and six hours.

[0067] Step 3: The drag chain cable 5 inside the sealed chamber 211 is alternately stationary and moved by two sets of operating simulation mechanisms 3; during this process, the appearance of the drag chain cable 5 is detected by a high-definition camera inside the sealed chamber 211.

[0068] Step 4: After wear appears on the surface of the drag chain cable 5, record the number of times the drag chain cable 5 is stationary and the number of times it is moved. After the drag chain cable 5 has been moved a certain number of times, check the appearance of the drag chain cable 5 again with a high-definition camera. At the same time, connect the moving end of the drag chain cable 5 through the detection mechanism 4 and test the electrical performance of the drag chain cable 5.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
