Description

Technical Field

[0001] This invention relates to the field of cable simulation testing technology, and in particular to a method and system for simulating cable laying tests. Background Technology

[0002] Cable: A cable is typically a rope-like structure made up of several or more strands of conductors twisted together. Each strand of conductor is insulated from the others and is often twisted around a central conductor, with the entire structure covered by a highly insulating outer layer. Cables are characterized by internal conductivity and external insulation. Types of cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single or multiple strands of conductors and an insulation layer, used to connect circuits and electrical appliances.

[0003] Existing cable laying simulation tests, when simulating the soil pressure experienced by cables buried underground, often only conduct simulated pressure tests in a single direction, failing to perform multi-directional pressure tests, which affects the accuracy and effectiveness of the simulation test results. Summary of the Invention

[0004] This invention discloses a method and system for simulating cable laying tests, aiming to solve the technical problem that existing cable laying simulation test systems in the background art cannot complete multi-directional compression tests on cables.

[0005] This invention proposes a system for simulating cable laying tests, comprising a test bench with a base fixedly connected to its bottom. A cable is placed on the test bench, and a multi-directional pressure test module is installed outside the cable. The multi-directional pressure test module includes an adjustment frame, a mounting base movably connected to one side of the adjustment frame, and four circumferentially equidistant movable grooves on the side of the mounting base away from the adjustment frame. Each movable groove contains a pressing block slidably connected to it, all located outside the cable. A sliding groove is formed on the inner wall of each movable groove near the adjustment frame, and a shaft is slidably connected to each sliding groove. The four shafts are fixedly connected to the sides opposite the four pressing blocks. The adjustment frame has four circumferentially equidistant curved grooves, and the outer sides of the shafts are slidably connected to the inner walls of the curved grooves. A shear strength test module is installed outside the multi-directional pressure test module, and a tensile strength test module is installed outside the cable. The tensile strength test module is located on the test bench.

[0006] Equipped with a test bench, base, multi-directional pressure test module, shear force test module, tensile test module, and cable, the device can apply pressure to the cable in multiple directions during the simulated cable compressive strength test using the multi-directional pressure test module. This allows the device to help testers simulate the pressure state of the cable under actual laying conditions to the greatest extent possible, ensuring the simulation test closely matches reality and improving the accuracy of the simulation test.

[0007] In a preferred embodiment, a mounting plate is fixedly connected to the outside of the mounting base. The mounting plate has a circular groove, the inner wall of which is fixedly connected to the outside of the mounting base. A connector is fixedly connected to the outside of the mounting plate. A second motor is fixedly connected to the side of the connector near the adjusting frame. The output end of the second motor is connected to a first gear via a coupling. A gear ring is fixedly connected to the outside of the adjusting frame, and the gear ring meshes with the first gear. An arc-shaped rack is fixedly connected to the outside of the adjusting frame. A short shaft is fixedly connected to the side of the mounting plate near the adjusting frame. A locking element is provided on the outside of the short shaft. The locking element and the arc-shaped rack are connected to each other. The short shaft is engaged, and a torsion spring surrounds its outer side. One end of the torsion spring is fixedly connected to the outside of the short shaft, and the other end is fixedly connected to the inner wall of the locking member. A strip groove is provided on the test platform, and the inner wall of the strip groove is slidably connected to the outside of the connecting member. Two symmetrical fixing blocks are fixedly connected to the side of the test platform away from the mounting plate. The same lead screw is movably connected to the two fixing blocks. A movable block is provided on the outside of the lead screw, and the movable block is fixedly connected to the side opposite to the mounting plate. A motor is fixedly connected to one side of one of the fixing blocks. The output end of the motor is connected to one side of the lead screw through a coupling.

[0008] By incorporating a multi-directional pressure test module, which utilizes movable blocks, movable grooves, and compression blocks, the cable can withstand pressure from multiple directions simultaneously during testing. Furthermore, the locking mechanism and arc-shaped rack allow the pressure to be maintained for an extended period. This enables the device to quickly detect the cable's stress limit, significantly shortening the testing process and improving the efficiency of the simulation test while ensuring the test results.

[0009] In a preferred embodiment, the shear force testing module includes two symmetrical connecting seats, both of which are fixedly connected to the outside of the mounting base. The connecting seats are located on the side of the mounting plate away from the adjustment frame. Each of the two connecting seats has a storage slot 1 and a storage slot 2, which are symmetrically offset. Shear blocks are slidably connected within each of the storage slots. A stabilizing frame is fixedly connected to the outside of each of the two connecting seats. Each stabilizing frame has a circular opening, within which a sleeve is fixedly connected. A hydraulic rod is fixedly connected within each sleeve, and the output end of each hydraulic rod is fixedly connected to the outside of a shear block on the same connecting seat.

[0010] By incorporating a shear force testing module, which utilizes two intersecting shear blocks, the device can apply sufficient shear force to the cable. This allows the device to test the cable's shear resistance while simultaneously performing a compression test, increasing the number of installation scenarios that can be simulated and improving the device's applicability.

[0011] In a preferred embodiment, the tensile testing module includes a protrusion, the upper side of which is fixedly connected to the bottom of the test bench. A bidirectional threaded rod is movably connected to the protrusion, and two symmetrical support plates are provided on the outside of the bidirectional threaded rod. A notch is provided on the protrusion, and a gear two is fixedly connected to the outside of the protrusion. The outside of the gear two is slidably connected to the inner wall of the notch. A motor three is fixedly connected to the bottom of the test bench, and the output end of the motor three is connected to the gear three via a coupling. The gear three meshes with the gear two. Two symmetrical rectangular grooves are provided on the inner wall of the bottom of the test bench, and the inner walls of the two rectangular grooves are respectively connected to... The two support plates are externally slidably connected, and the bottom inner wall of the test bench is provided with two symmetrical scale grooves. A pointer is fixedly connected to the side of the support plate that is cut into the scale groove, and the two pointers are respectively located above the two scale grooves. The support plates are all provided with slots, and the inner walls of the slots are fixedly connected with external connectors. The inner walls of the external connectors are slidably connected to the outside of the cable, and the outside of the external connectors are provided with threaded grooves. The outside of the external connectors is provided with rotating rings, and the inner walls of the rotating rings are rotatably connected to the threaded grooves through external threads. The external connectors are provided with multiple circumferentially distributed grooves.

[0012] By incorporating a tensile testing module, the device can improve the fixation of the cable during the test by using an external connector and a rotating ring, ensuring that the cable will not shift during the simulation test and thus affect the test process. The movable support plate also expands the test content of the device's simulation test and improves the diversity of the test.

[0013] A method for simulating cable laying tests, using a system for simulating cable laying tests as described above, includes the following steps:

[0014] Step 1: After placing the cable into the test bench, use the tensile testing module to fix the cable and conduct a tensile test;

[0015] Step 2: After the tensile test is completed, use the multi-directional compressive testing module to conduct multi-directional compressive tests on the cable;

[0016] Step 3: After the compression test is completed, use the shear force test module to conduct a shear force test on the cable. After completion, remove the cable and place the next cable into the test bench to start the next simulation test.

[0017] As can be seen from the above, the system for simulating cable laying test provided by the present invention can apply pressure to the cable in multiple directions when simulating the cable's compressive strength test, so that the device can help the test personnel to simulate the pressure state received by the cable under the display laying state to the greatest extent, ensure the closeness of the simulation test to reality, and improve the accuracy of the simulation test.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The system for simulating cable laying tests disclosed in this invention is mainly applied to scenarios where existing cable laying simulation test systems cannot perform multi-directional compression tests on cables.

[0028] Reference Figure 1-7 A system for simulating cable laying tests includes a test bench 1, with a base 2 bolted to the bottom of the test bench 1. A cable 6 is placed on the test bench 1, and a multi-directional pressure test module 3 is installed outside the cable 6. The multi-directional pressure test module 3 includes an adjustment frame 308, and a mounting base 309 is rotatably connected to one side of the adjustment frame 308 via a bearing. Four circumferentially spaced movable grooves 310 are opened on the side of the mounting base 309 away from the adjustment frame 308. Each movable groove 310 has a slidably connected compression block 311, and the compression blocks 311 are all located outside the cable 6. Furthermore, the inner wall of the movable groove 310 near the adjustment frame 308 is provided with a sliding groove 312, and a shaft 313 is slidably connected in the sliding groove 312. The four shafts 313 are respectively connected to the opposite side of the four extrusion blocks 311 by bolts. The adjustment frame 308 is provided with four circumferentially distributed curved grooves 314. The outer side of the shafts 313 is slidably connected to the inner wall of the curved grooves 314. The multi-directional pressure test module 3 is provided with a shear force test module 4 on its outside, and the cable 6 is provided with a tensile test module 5 on its outside. The tensile test module 5 is located on the test bench 1.

[0029] Specifically, after placing cable 6 into test bench 1, tensile test module 5 is used to fix cable 6 and perform tensile test. After the tensile test is completed, multi-directional pressure test module 3 is used to perform multi-directional pressure test on cable 6. After the pressure test is completed, shear force test module 4 is used to perform shear force test on cable 6. After completion, cable 6 is removed, and the next cable 6 is placed into test bench 1 to start the next simulation test. The device uses multi-directional pressure test module 3 to apply pressure to the cable in multiple directions when simulating the cable's compressive strength test, so that the device can help the test personnel to simulate the pressure state received by the cable under the display laying state to the greatest extent, ensuring the closeness of the simulation test to reality and improving the accuracy of the simulation test.

[0030] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, a mounting plate 307 is bolted to the outside of the mounting base 309. The mounting plate 307 has a circular groove 315, the inner wall of which is bolted to the outside of the mounting base 309. A connector 306 is bolted to the outside of the mounting plate 307. A second motor 317 is bolted to the side of the connector 306 near the adjusting frame 308. The output end of the second motor 317 is connected to a first gear 318 via a coupling. A gear ring 316 is bolted to the outside of the adjusting frame 308, and the gear ring 316 meshes with the first gear 318. An arc-shaped rack 322 is bolted to the outside of the adjusting frame 308. A short shaft 319 is bolted to the side of the mounting plate 307 near the adjusting frame 308. A locking element 320 is provided on the outside of the short shaft 319. 0 meshes with the arc-shaped rack 322, and a torsion spring 321 surrounds the outside of the short shaft 319. One end of the torsion spring 321 is bolted to the outside of the short shaft 319, and the other end is bolted to the inner wall of the locking member 320. A strip groove 305 is provided on the test bench 1. The inner wall of the strip groove 305 is slidably connected to the outside of the connecting member 306. Two symmetrical fixing blocks 301 are bolted to the side of the test bench 1 away from the mounting plate 307. The same lead screw 302 is rotatably connected to the two fixing blocks 301 through bearings. A movable block 304 is provided on the outside of the lead screw 302. The movable block 304 is bolted to the side opposite to the mounting plate 307. A motor 303 is bolted to one side of one of the fixing blocks 301. The output end of the motor 303 is connected to one side of the lead screw 302 through a coupling.

[0031] Specifically, after the device fixes both ends of the cable 6 and inserts the cable 6 into the adjusting frame 308, the first motor 303 is started. The first motor 303 drives the lead screw 302 to rotate, thereby causing the movable block 304 on the lead screw 302 to move the mounting plate 307 connected to the connector 306 laterally. This allows the adjusting frame 308 to select a test position on the cable 6. The second motor 317 is then started, driving the gear ring 316 meshing with the gear 318 to rotate. This causes the adjusting frame 308 connected to the gear ring 316 to rotate. The rotating adjusting frame 308 drives the curved groove 314 to rotate, causing the curved groove 314 to push the pressing block 311 connected to the shaft 313 to move towards the cable 6 on the movable groove 310. As the adjusting frame 308 continues to rotate, the gradually tightening compression block 311 will apply increasing pressure to the cable 6. At the same time, under the torque of the torsion spring 321, the locking member 320 will lock the position of the adjusting frame 308 connected to the arc-shaped rack 322, so that the adjusting frame 308 will not rotate under the action of reaction force. After observing and recording the changes of the cable 6 under pressure, the locking member 320 is moved to release the lock on the adjusting frame 308. The second motor 317 reverses, causing the compression block 311 to leave the cable 6. The first motor 303 is started again, causing the movable block 304 to move the adjusting frame 308 to the next position on the cable 6, and the next test is started. The above operation is repeated many times and the data is recorded.

[0032] In specific application scenarios, the multi-directional pressure test module 3 is mainly suitable for the multi-directional pressure test stage in the multi-directional pressure test process. That is, the multi-directional pressure test module 3 uses the movable block 304, the movable groove 310 and the compression block 311 to enable the cable 6 to bear pressure in multiple directions at the same time during the test, and uses the locking part 320 and the arc-shaped rack 322 to maintain the pressure for a long time. In this way, the device can quickly detect the stress limit of the cable 6, which greatly shortens the test process and improves the efficiency of simulation test while ensuring the test effect.

[0033] Reference Figure 5In a preferred embodiment, the shear force test module 4 includes two symmetrical connecting seats 401. Both connecting seats 401 are bolted to the outside of the mounting base 309. The connecting seats 401 are located on the side of the mounting plate 307 away from the adjustment frame 308. The two connecting seats 401 are respectively provided with a first storage groove 402 and a second storage groove 403. The positions of the first storage groove 402 and the second storage groove 403 are staggered and symmetrical. Shear blocks 404 are slidably connected in both the first storage groove 402 and the second storage groove 403. Stabilizers 405 are bolted to the outside of both connecting seats 401. Each stabilizer 405 has a round opening. A sleeve 406 is bolted to the round opening. A hydraulic rod 407 is bolted to the sleeve 406. The output end of the hydraulic rod 407 is bolted to the outside of the shear block 404 on the same connecting seat 401.

[0034] Specifically, after the compression test is completed, the hydraulic rod 407 is activated. The hydraulic rod 407 drives the connected shearing blocks 404 to move from the first storage slot 402 and the second storage slot 403 toward the cable 6. When the shearing blocks 404 come into contact with the cable 6 and continue to advance, the two horizontally staggered shearing blocks 404 will generate shearing force on the cable 6 in the direction of force on the cable 6. As the hydraulic rod 407 continues to push, the cable 6 will eventually break under the action of shearing force. The data of the shear test is recorded and multi-point tests are carried out.

[0035] In specific application scenarios, the shear force test module 4 is mainly suitable for the shear force test stage in the shear force test process. That is, the shear force test module 4 uses two shear blocks 404 with intersecting positions to enable the device to exert sufficient shear force on the cable 6, so that the device can test the shear resistance of the cable 6 at the same time as performing the compression test on the cable 6, increasing the number of laying scenarios simulated by the device and improving the applicability of the device.

[0036] Reference Figure 6 and Figure 7In a preferred embodiment, the tensile testing module 5 includes a protrusion 501. The upper side of the protrusion 501 is bolted to the bottom of the test bench 1. A bidirectional threaded rod 502 is rotatably connected to the protrusion 501 via a bearing. Two symmetrical support plates 503 are provided on the outside of the bidirectional threaded rod 502. A notch is provided on the protrusion 501. A gear 511 is bolted to the outside of the protrusion 501. The outside of the gear 511 is slidably connected to the inner wall of the notch. A motor 512 is bolted to the bottom of the test bench 1. The output end of the motor 512 is connected to a gear 513 via a coupling. The gear 513 meshes with the gear 511. Two symmetrical rectangular grooves 504 are provided on the inner wall of the bottom of the test bench 1. The test bench 1 is slidably connected to the outside of two support plates 503, and the bottom inner wall of the test bench 1 is provided with two symmetrical scale grooves 505. The support plates 503 are bolted to the side of the scale grooves 505, and the two pointers 506 are located above the two scale grooves 505 respectively. The support plates 503 are provided with slots, and the inner walls of the slots are bolted to the outer wall of the outer wall connectors 507. The inner walls of the outer wall connectors 507 are slidably connected to the outside of the cable 6, and the outer wall connectors 507 are provided with threaded grooves 508. The outer wall connectors 507 are provided with rotating rings 510. The inner walls of the rotating rings 510 are rotatably connected to the threaded grooves 508 through external threads. The outer wall connectors 507 are provided with multiple circumferentially distributed grooves 509.

[0037] Specifically, after passing both ends of cable 6 through the outer connector 507, the rotating ring 510 is rotated. As the rotating ring 510 moves toward cable 6, its inner wall pushes the outer connector 507 inward to tighten, thus fixing cable 6. Motor 3 512 is then started, driving gear 2 511, which meshes with gear 3 513, to rotate. This causes the bidirectional threaded rod 502, connected to gear 2 511, to move the two support plates 503 away from gear 2 511. With the outer connector 507 fixed on the support plates 503, the gears 3 513, moving away from each other, pull on cable 6, forcing it to stretch. As cable 6 stretches, the pointer 506 connected to the support plates 503 indicates the stretching distance of cable 6 on the scale groove 505, recording the data.

[0038] In specific application scenarios, the tensile test module 5 is mainly suitable for the tensile test stage in the tensile test process. That is, the tensile test module 5 can improve the fixation of the cable 6 during the test by using the outer connector 507 and the rotating ring 510, ensuring that the cable 6 will not deviate during the simulation test and thus affect the test process. The movable support plate 503 also expands the test content of the device simulation test and improves the diversity of the test.

[0039] A method for simulating cable laying tests, using a system for simulating cable laying tests as described above, includes the following steps:

[0040] Step 1: After placing the cable 6 into the test bench 1, use the tensile test module 5 to fix the cable 6 and conduct a tensile test (after passing both ends of the cable 6 through the outer connector 507, rotate the rotating ring 510. As the rotating ring 510 moves toward the cable 6, the inner wall of the rotating ring 510 will push the outer connector 507 inward to tighten, thereby fixing the cable 6. Start the motor 3 512. The motor 3 512 drives the gear 2 511, which meshes with the gear 3 513, to rotate. This causes the bidirectional threaded rod 502 connected to the gear 2 511 to drive the two support plates 503 to move away from the gear 2 511. Under the fixation of the outer connector 507 on the support plate 503, the gear 3 513, which moves away from each other, will pull the cable 6 during the movement, forcing the cable 6 to stretch under force. As the cable 6 stretches, the pointer 506 connected to the support plate 503 will indicate the stretching distance of the cable 6 on the scale groove 505. Record the data).

[0041] Step 2: After the tensile test is completed, the multi-directional pressure test module 3 is used to conduct a multi-directional pressure test on the cable 6 (start motor 1 303, motor 1 303 drives the lead screw 302 to rotate, thereby causing the movable block 304 on the lead screw 302 to drive the mounting plate 307 connected to the connector 306 to move laterally, so that the adjusting frame 308 can select the test position on the cable 6; start motor 2 317, motor 2 317 drives the gear ring 316 meshing with gear 1 318 to rotate, thereby causing the adjusting frame 308 connected to the gear ring 316 to rotate, the rotating adjusting frame 308 drives the curved groove 314 to rotate, so that the curved groove 314 pushes the extrusion block 311 connected to the shaft 313 on the movable groove 310 towards the cable). As cable 6 moves, the gradually tightening compression block 311 applies increasing pressure to cable 6 as the adjusting frame 308 continues to rotate. Simultaneously, under the torque of the torsion spring 321, the locking member 320 locks the position of the adjusting frame 308 connected to the arc-shaped rack 322, preventing the adjusting frame 308 from rotating due to the reaction force. After observing and recording the changes in cable 6 under pressure, the locking member 320 is moved to release the locking of the adjusting frame 308. Motor 2 317 reverses, causing the compression block 311 to leave cable 6. Motor 1 303 is restarted, causing the movable block 304 to move the adjusting frame 308 to the next position on cable 6, and the next test is started. The above operation is repeated multiple times and the data is recorded.

[0042] Step 3: After the compression test is completed, use the shear force test module 4 to conduct a shear force test on cable 6. After completion, remove cable 6 and place the next cable 6 into test bench 1 to start the next simulation test. (After the compression test is completed, start the hydraulic rod 407. The hydraulic rod 407 drives the connected shear block 404 to move from the storage slot 1 402 and storage slot 2 403 towards cable 6. When the shear block 404 contacts cable 6 and continues to advance, the two horizontally staggered shear blocks 404 will generate shear force on cable 6 in the direction of force on cable 6. As the hydraulic rod 407 continues to push, cable 6 will eventually break under the action of shear force. Record the data of the shear test and conduct multi-point tests.)
