Description

Technical Field

[0001] This utility model belongs to the field of cable production technology, specifically a wear resistance testing device for low-voltage cable production. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. These conductors are generally made of metals with good conductivity, such as copper or aluminum. Taking a common power cable as an example, its basic structure includes a conductor, an insulation layer, a shielding layer, and a protective layer. The protective layer is the outermost layer of the cable and mainly serves a mechanical protection function, preventing the cable from being damaged by external physical forces, such as friction, compression, and corrosion. Protective layer materials include polyethylene (PE) and rubber. PE protective layers have good wear resistance and corrosion resistance, while rubber protective layers have good elasticity and flexibility, which can buffer external impacts to a certain extent.

[0003] Cable abrasion resistance testing is an important step in ensuring that cable products have good abrasion resistance in practical applications. Abrasion resistance refers to the cable's ability to resist friction and wear, which is crucial to the cable's service life and reliability.

[0004] Existing abrasion resistance testing devices for cable production can typically only clamp and fix cables of the same model. When fixing and testing cables of different models and sizes, parts need to be replaced, which leads to cumbersome operation. Utility Model Content

A motor is fixedly connected to the top of each of the first fixed blocks; the output end of the motor is fixedly connected to one end of one of the multiple rotating shafts; a fixed ring is fixedly connected to the side wall of the second gear; multiple sets of spring telescopic rods are fixedly connected to the inner side wall of the fixed ring; a detection head is fixedly connected to the end of the spring telescopic rod; multiple second fixed blocks are fixedly connected to the top of the detection platform; by setting multiple first gears and second gears to operate in coordination, the fixed ring can be rotated at high speed to quickly rub the surface of the cable to be tested inside, and detect the degree of wear on its sheath. At the same time, the setting of the spring telescopic rods can freely adjust the size of the space on the side wall of the fixed ring to adapt to different models and sizes of cables, reduce the time for changing equipment, and improve its usage efficiency.

[0009] Preferably, the testing platform has multiple tracks inside; a collection box is connected to the side wall of the track; the collection box and the track are slidably connected; by setting up the collection box, it can collect the debris that falls off the upper part of the testing platform during testing when testing the cable, and can also collect excess water mist from the upper part, avoiding excessive water mist remaining on the surface of the testing platform, which may cause equipment failure. At the same time, the debris and water mist collected in the collection box can be emptied when needed for subsequent use.

[0010] Preferably, a plurality of third fixing blocks are fixedly connected to the top of the testing platform; rubber blocks are fixedly connected to the side walls of the third fixing blocks; by setting rubber blocks, not only can the friction between the rubber blocks and the cable surface be utilized to prevent the cable from twisting, but the cable surface can also be protected from damage when fixing the cable.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 2As shown in the embodiment of this utility model, a wear-resistant testing device for low-voltage cable production includes a testing platform 1; multiple sets of first connecting rods 15 are fixedly connected to the top of the testing platform 1; the multiple sets of first connecting rods 15 are symmetrically arranged; a pair of second connecting rods 16 are fixedly connected to the middle of each set of first connecting rods 15; ball bearings 14 are fixedly connected to the ends of the second connecting rods 16; a rotating shaft 13 is fixedly connected inside the ball bearing 14; multiple transmission components are provided between the multiple rotating shafts 13; the transmission components include multiple first gears 17 fixedly connected to the rotating shafts 13; and second gears 18 are provided between the multiple first gears 17; The second gear 18 and the first gear 17 are meshed together; a pair of first fixing blocks 11 are fixedly connected to the top of the testing platform 1; a motor 12 is fixedly connected to the top of each pair of first fixing blocks 11; the output end of the motor 12 is fixedly connected to one end of one of the plurality of rotating shafts 13; a fixing ring 19 is fixedly connected to the side wall of the second gear 18; a plurality of spring telescopic rods 110 are fixedly connected to the inner side wall of the fixing ring 19; a detection head 111 is fixedly connected to the end of the spring telescopic rod 110; a plurality of second fixing blocks 112 are fixedly connected to the top of the testing platform 1; in use, first open the latch of the second fixing block 112, and insert the electrical device to be tested. The cable is passed through multiple fixing rings 19, causing the cable's volume to compress multiple detection heads 111 outwards. This compresses multiple spring telescopic rods 110, and the elasticity of the spring telescopic rods 110 causes the detection heads 111 to exert a compressive force on the cable surface, thus securing the cable. After securing the cable, the motor 12 is switched on to start operation. The motor 12 drives the rotating shaft 13 to rotate, and the first gear 17 also rotates with the shaft 13. Since the first gear 17 and the second gear 18 are meshed, the multiple first gears 17... The meshing structure of the first gear 17 and the second gear 18 will rotate together, causing the fixed ring 19 to start rotating. The rotation of the fixed ring 19 will cause the detection head 111 on the side wall to rotate together. The detection head 111 contacts the surface of the cable. By setting multiple first gears 17 and second gears 18 to work together, the fixed ring 19 can rotate at high speed, quickly rubbing the surface of the cable to be tested inside, and detecting the degree of wear on its sheath. At the same time, the setting of the spring telescopic rod 110 can freely adjust the size of the space on the side wall of the fixed ring 19 to adapt to different models and sizes of cables, reducing the time for changing equipment and improving its efficiency.

[0024] like Figure 1As shown, a first pipe 2 is fixedly connected to the top of the first connecting rod 15; an inlet 21 is fixedly connected to the side wall of the first pipe 2; multiple second pipes 22 are fixedly connected to the side wall of the first pipe 2; multiple outlet holes 23 are opened at the ends of the second pipes 22; the first pipe 2 is internally connected to the inlet 21 and the second pipes 22; in use, a water pump is connected to the end of the inlet 21, so that a large amount of water enters the interior of the first pipe 2 through the inlet 21. At this time, a large amount of water will flow along the inner wall of the first pipe 2 into the interior of the multiple second pipes 22, and then be sprayed outward through the outlet holes 23. By setting multiple second pipes 22 and outlet holes 23, water mist can be sprayed onto the surface of the cable when testing its abrasion resistance, simulating the humid environment of the cable in actual application, making the test results closer to reality, thereby indirectly placing higher quality requirements on cable manufacturers and improving product quality.

[0025] like Figure 3 As shown, a third pipe 3 is fixedly connected to the top of the first connecting rod 15; an air inlet 31 is fixedly connected to the side wall of the third pipe 3; multiple fourth pipes 32 are fixedly connected to the side wall of the third pipe 3; multiple air outlets 33 are opened at the ends of the fourth pipes 32; the third pipe 3 is internally connected to the air inlet 31 and the fourth pipes 32; in use, a hot air pump is connected to the end of the air inlet 31, so that a large amount of air enters the interior of the third pipe 3 through the air inlet 31. At this time, a large amount of air will flow along the inner wall of the third pipe 3 into the interior of the multiple fourth pipes 32, and then blow out through the air outlets 33. By setting multiple fourth pipes 32 and air outlets 33, air can be blown onto the surface of the cable when testing its abrasion resistance, simulating the wind environment of the cable in actual application, and detecting the effect of weathering on its surface protective layer, making the test results closer to reality.

[0026] like Figure 4 As shown, the testing platform 1 has multiple tracks 4 inside; a collection box 41 is connected to the side wall of the track 4; the collection box 41 and the track 4 are slidably connected; in use, the collection box 41 is installed on the side wall of the track 4 so that it can move smoothly along the side wall of the track 4. By setting the collection box 41, it can collect the debris that falls off the upper part of the testing platform 1 during the testing of the cable, and can also collect the excess water mist on the upper part, so as to avoid too much water mist remaining on the surface of the testing platform 1 and causing equipment failure. At the same time, the debris and water mist collected in the collection box 41 can be emptied when needed for subsequent use.

[0027] like Figure 5As shown, multiple third fixing blocks 5 are fixedly connected to the top of the testing platform 1; rubber blocks 51 are fixedly connected to the side walls of the third fixing blocks 5; in use, the rubber blocks 51 are fixed on the top of the third fixing blocks 5, and the cable is placed on the surface of the rubber blocks 51 to prevent it from falling off. By setting the rubber blocks 51, not only can the friction between the rubber blocks 51 and the surface of the cable be utilized to prevent it from twisting, but the surface of the cable can also be protected from damage when fixing the cable. At the same time, it can also reduce the torsional deformation caused by high-speed rotation during the testing process, making the test results more accurate.

[0028] like Figure 5 As shown, an elastic rope 6 is fixed to the top of the third fixing block 5; the elastic rope 6 is arc-shaped; in use, the elastic rope 6 is pulled so that the space enclosed by the elastic rope 6 and the top of the third fixing block 5 can pass through the cable, and then the cable is placed on the surface of the rubber block 51. By setting the elastic rope 6, the size of the space enclosed by the elastic rope 6 and the top of the third fixing block 5 can be adjusted to adapt to different types of cables. At the same time, the cable can better fit the surface of the rubber block 51, making it firmly fixed to the top of the third fixing block 5, reducing torsional deformation caused by high-speed rotation during the testing process.

[0029] Working principle: In use, first open the slot of the second fixing block 112, insert the cable to be tested, and let the cable pass through the multiple fixing rings 19. The volume of the cable itself squeezes the multiple detection heads 111 outward, thereby compressing the multiple spring telescopic rods 110. Under the elasticity of the spring telescopic rods 110, the detection heads 111 exert a squeezing force on the cable surface, achieving the cable fixing effect. After fixing the cable, turn on the switch of the motor 12 to start working. The motor 12 will drive the rotating shaft 13 to rotate together, and the first gear 17 will also rotate with the rotating shaft 13. Since the first gear 17 and the second gear 18 are meshed, the meshing structure of multiple first gears 17 and second gears 18 will rotate together, driving the fixing rings 19 to start rotating. The rotation of the fixing rings 19 will drive the detection heads 111 on the side wall to rotate together. The detection heads 111 and the motor... The surface of the cable is in contact with a water pump connected to the end of the inlet 21, allowing a large amount of water to enter the interior of the first pipe 2 through the inlet 21. At this time, a large amount of water will flow along the inner wall of the first pipe 2 into the interior of multiple second pipes 22, and then be sprayed outward through the outlet 23. A hot air pump is connected to the end of the air inlet 31, allowing a large amount of air to enter the interior of the third pipe 3 through the air inlet 31. At this time, a large amount of air will flow along the inner wall of the third pipe 3 into the interior of multiple fourth pipes 32, and then be blown outward through the outlet 33. A collection box 41 is installed on the side wall of the track 4, allowing it to move smoothly along the side wall of the track 4. A rubber block 51 is fixed on the top of the third fixing block 5, and the cable is placed on the surface of the rubber block 51 to prevent it from falling off. The elastic rope 6 is pulled so that the space enclosed by the elastic rope 6 and the top of the third fixing block 5 can pass through the cable, and then the cable is placed on the surface of the rubber block 51.
