Description

Technical Field

[0001] The present invention relates to the field of cable structure detection, and in particular to a cable structure strength detection device and a detection method. Background Art

[0002] Cables are an indispensable infrastructure in modern life. They are widely used in various fields such as power transmission, communication networks, and equipment connections. When in use, cables are usually installed on poles or laid on the ground. Their working environment is relatively harsh. Therefore, after the cable is produced, in order to ensure its safety and reliability, the structural strength of the cable needs to be tested to ensure that it can be used normally.

[0003] The Chinese patent application number CN202111251909.0 discloses an apparatus and method for detecting the tensile strength of a cable, the apparatus includes a mounting frame, a clamping mechanism and a detection mechanism; there are at least two clamping mechanisms, and each clamping gap is adjustable and the displacement of the central axis will not change with the adjustment change, so that it can well meet the test of cables of various diameters and sizes, and improve the versatility. Furthermore, the clamping mechanism is adjustable along the central axis direction of its own clamping gap, which improves the detection accuracy. The detection head, trigger and alarm are used in combination. During the detection, the detection head moves around the outer peripheral surface of the cable to be tested by driving the sliding seat to move, and when the tensile strength of the cable to be tested is insufficient, the movable column changes in displacement, triggering the switch so that the alarm sends an alarm signal, prompting the operator that the tensile strength of the cable to be tested is insufficient. However, in the clamping process of this patent, the friction force is insufficient or too large, which can easily cause the cable to fall off or damage the surface of the cable insulation, causing the insulation to fall off from the cable core, affecting the detection results.

[0004] The existing strength detection device can usually only perform tensile and torsion tests on the cable. The tensile test and torsion test cannot be performed simultaneously, and the daily use of the cable cannot be simulated. In addition, during the detection process, the existing strength detection device can only judge whether the cable is broken during the test by the naked eye, and the slight changes in the cable cannot be known. Therefore, the detection accuracy of the cable strength by the existing detection device is low. However, when the strength of the cable is detected by the above-mentioned existing technology, the following problems still exist: the above-mentioned detection can only perform tensile tests on the cable, but cannot perform torsion or other tests on the cable, so the applicability is low. When clamping the cable, the staff still needs to clamp the cable by turning multiple bolts. Tightening the bolts cannot ensure whether the clamping uniformity of the outside of the cable is consistent. The cable is stretched. When testing some thicker cables, the torque of the motor is too small, and the pulling force on the cable cannot produce a test effect on it, which can easily cause the motor to fail.

[0005] Therefore, a cable structure strength detection device and detection method are invented to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a cable structure strength detection device, which aims to solve the problem that insufficient or excessive friction during the clamping process may easily cause the cable to fall off or damage the surface of the cable insulation, causing the insulation and the cable core to fall off, affecting the detection results.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] like Figure 1 As shown, it includes a base plate 1, and several support members 10 are arranged on the upper end of the base plate 1. A main board 11 is arranged on the upper end of each support member 10. Side panels 12 are symmetrically arranged on both sides of the main board 11. The support members 10 are used to support the main board 11, and the main board 11 can support the side panels 12. The side panels 12 are rotatably connected with a screw rod 13, and the screw rod 13 can rotate under the limit of the side panels 12 on both sides.

[0044] like Figures 2 to 4As shown, the clamping assembly 2 is arranged on the screw rod 13, and the clamping assembly 2 can clamp the cable. When the screw rod 13 rotates, it can drive the clamping assembly 2 to move. When the clamping assembly 2 moves, the cable can be tensile tested. The clamping assembly 2 for clamping the cable includes two thread grooves 20 symmetrically arranged on the screw rod 13. The two thread grooves 20 are symmetrically arranged on the outside of the screw rod 13, and the extension directions of the two thread grooves 20 are opposite. The outside of the screw rod 13 is symmetrically provided with thread grooves 20 corresponding to the thread grooves 20. The driven ring 21 is threadedly connected, and a driving member 22 is arranged on the outside of the driven ring 21. A rotating plate 23 is arranged on the driving member 22. The rotating plate 23 is arranged in a circular shape. A limiting groove 24 is arranged in the middle of the main board 11. A limiting plate 25 located in the limiting groove 24 is arranged on the outside of the driven ring 21. The limiting plate 25 can limit the driven ring 21 through the limiting groove 24, so that when the screw rod 13 rotates, the driving ring 34 can be driven to move horizontally through the thread groove 20, that is, the extension direction of the thread groove 20 is opposite, so the two driven The moving directions of the ring 21 are opposite, and when the driven ring 21 moves, it can drive the driving member 22 and the rotating plate 23 to move synchronously. A rotating cavity 26 is opened in the rotating plate 23, and the inner wall of one side of the rotating cavity 26 is rotatably connected to a limiting shaft 27. A threaded disk 28 located in the rotating cavity 26 is arranged outside the limiting shaft 27. The limiting shaft 27 can rotate on the inner wall of the rotating cavity 26, and at the same time, the threaded disk 28 is limited so that the threaded disk 28 can rotate along its axis in the rotating cavity 26. The opposite ends of the two rotating plates 23 are opened. There is a fixed groove 29 that intersects with the corresponding rotating cavity 26, and one end of the rotating plate 23 is also provided with a plurality of strip grooves 210 that are evenly distributed along its axis and intersect with the corresponding fixed groove 29 and the rotating cavity 26. A sliding plate 211 that is threadedly connected to the corresponding threaded disk 28 is slidably arranged in the strip groove 210. The sliding plate 211 can move toward or away from the axis of the fixed groove 29 under the limitation of the corresponding strip groove 210. When the threaded disk 28 rotates, it can drive the sliding plate 211 to move synchronously.

[0045] like Figures 2 to 6As shown, a clamping plate 212 is provided at one end of each sliding plate 211 close to the fixed groove 29. The clamping plate 212 is arranged in an arc shape to adapt to the cable surface. A first airbag 213 is fixedly connected to the outer wall of each clamping plate 212. The first airbag 213 has elasticity to adapt to different cable shapes. Two second airbags 219 are fixedly connected to the inner wall of the limiting groove 24. The opposite ends of the second airbags 219 are both in contact with the outer wall of the limiting plate 25 in the initial state. The second airbag 219 is connected to the first airbag 213 through a connecting pipe. The end of the connecting pipe away from the second airbag 219 is connected to the first airbag 213 through a tap. When the second airbag 219 is connected to the first airbag 213, the first airbag 213 is connected to the first airbag 213 through a tap. When the limiting plate 25 moves and squeezes 219, the internal gas of the second airbag 219 enters the first airbag 213 evenly through the connecting tube. The sliding plate 211 can drive the clamping plate 212 to move in the fixed groove 29 when moving. When several clamping plates 212 are driven together by the sliding plate 211, they can be combined into a small circle. The first airbag 213 fits tightly against the cable surface, and the pressure inside the first airbag 213 is increased to apply pressure to the cable surface. The greater the pressure, the greater the friction, which can prevent the cable from falling off. At the same time, the clamping of the first airbag 213 can ensure that the cable surface is not damaged, thereby improving the accuracy of the cable detection results.

[0046] When clamping the cable, first place one end of the cable in the fixed groove 29 on the rotating plate 23 on one side. The sliding plate 211 can drive the clamping plate 212 to move in the fixed groove 29 when moving. When several clamping plates 212 are driven together by the sliding plate 211, they can be combined into a small circle. The first air bag 213 fits tightly with the surface of the cable. Then, place the other end of the cable in the fixed groove 29 in the middle of another rotating plate 23. Repeat the above steps. The first air bag 213 can increase the clamping friction of the cable, making it difficult for the cable to fall off the clamping plate 212. After the cable is clamped, the rotating plate 23 moves in the opposite direction again so that when the screw rod 13 rotates, it can drive the drive ring 34 to move horizontally through the thread groove 20, that is, the extension direction of the thread groove 20 is opposite, so the two The moving directions of the driven rings 21 are opposite, and when the driven rings 21 move, they can drive the driving member 22 and the rotating plate 23 to move synchronously. The driven ring 21 drives the limiting plate 25 to move in the opposite direction. The limiting plate 25 moves to squeeze the internal gas of the second airbag 219. The internal gas of the second airbag 219 enters the first airbag 213 evenly through the connecting pipe. The internal gas of the first airbag 213 increases, and the internal air pressure of the first airbag 213 increases to apply pressure to the cable surface. During the stretching process of the cable, the greater the stretching distance, the greater the pressure on the cable surface, and the greater the friction, thereby preventing the cable from falling off. At the same time, the clamping of the first airbag 213 can ensure that the cable surface is not damaged, thereby improving the accuracy of the cable detection results. The cable is indirectly pulled by the clamping plate 212, so that the cable is stretched, thereby performing a stretching test.

[0047] like Figures 2 to 4 As shown, an outer gear ring 214 is provided on the outer side of the threaded disk 28, and the outer gear ring 214 can drive the threaded disk 28 to rotate. A T-shaped ring groove 215 is also provided on the rotating plate 23, and one end of the T-shaped ring groove 215 penetrates to the outer side of the rotating plate 23. A driving rod 216 is rotatably connected in the T-shaped groove 41. A clamping gear 217 located in the T-shaped ring groove 215 and meshing with the outer gear ring 214 is provided on the outer side of the driving rod 216. A hexagonal groove 218 is provided on one end of the driving rod 216 located outside the rotating plate 23. When the staff indirectly controls the clamping plate 212 to clamp the cable, a hexagonal wrench is inserted into the hexagonal groove 218, and then the hexagonal wrench is inserted into the hexagonal groove 218. The hexagonal groove 218 drives the driving rod 216 to rotate in the T-shaped ring groove 215. When the driving rod 216 rotates, it can drive the clamping gear 217 to rotate synchronously, so that the clamping gear 217 can drive the outer gear ring 214 to rotate, so that the outer gear ring 214 drives the threaded disk 28 to rotate. When the threaded disk 28 rotates, it can drive the sliding plate 211 to move synchronously. When the sliding plate 211 moves, it can drive the clamping plate 212 to move in the fixed groove 29. When several clamping plates 212 are driven together by the sliding plate 211, they can be combined into a small circle, and the clamping plate 212 fits tightly against the outer surface of the cable.

[0048] like Figures 5 to 7As shown, the driving assembly 3 is arranged between the supporting members 10, and the driving assembly 3 includes two movable grooves 30 opened on the main board 11 and located at the front and rear sides of the limiting groove 24, which are used to drive the rotating plate 23 to rotate, and the rotating plate 23 is rotatably connected with the driving member 22, and a supporting plate 31 with one end passing through the movable groove 30 and located between the supporting members 10 is arranged on the front and rear sides of the driving member 22, and a rectangular frame 32 is arranged between the supporting plates 31. When the driving member 22 moves, it can drive the supporting plates 31 to move synchronously, and the movable groove 30 is used to enable the supporting plates 31 to pass through the lower end of the main board 11 and will not be limited by the main board 11. When the support plate 31 moves, it can drive the rectangular frame 32 to move synchronously, and an inner gear ring 33 is rotatably connected in the rectangular frame 32, and a driving ring 34 is arranged on one side of the rotating plate 23. The driving ring 34 and the inner gear ring 33 are connected by belt transmission, and the inner gear ring 33 can rotate in the rectangular frame 32. When rotating, the corresponding rotating plate 23 can be driven to rotate synchronously through the belt transmission and the driving ring 34. The rotating plate 23 indirectly drives the cable to twist through the clamping plate 212 to realize the torsion test of the cable. A rectangular plate 35 is arranged between the support members 10, and support blocks 36 are symmetrically arranged on both sides of the rectangular plate 35. A rotating shaft 37 passing through the inner gear ring 33 is rotatably connected between the support blocks 36. A bar gear 38 meshing with the inner gear ring 33 is sleeved on the outer side of the rotating shaft 37. The support member 10 can support the rectangular plate 35, and the rectangular plate 35 can support the support block 36, so that the support block 36 can limit the rotating shaft 37, that is, the rotating shaft 37 can rotate under the limit of the support block 36, and when the rotating shaft 37 rotates, it can drive the bar gear 38 to rotate synchronously, and when the bar gear 38 rotates, it can drive the inner gear ring 33 to rotate, thereby indirectly driving the rotating plate 23 to rotate.

[0049] like Figure 8 and Fig. 9As shown, the monitoring assembly 4 is arranged between the two side plates 12, and the monitoring assembly 4 includes a strip plate 40, which is arranged between the two side plates 12 and is used to detect the cable status. A T-shaped slot 41 is opened in the strip plate 40 and one end of the strip plate 40 passes through its lower end. A T-shaped plate 42 is slidably arranged in the T-shaped slot 41. The T-shaped plate 42 can slide in the T-shaped slot 41. An elastic member 43 is connected between the T-shaped plate 42 and the inner wall of the T-shaped slot 41. In the initial state, the elastic member 43 will give a driving force to the corresponding T-shaped plate 42, so that the distance between the two T-shaped plates 42 is close. A top extension cylinder 44 is arranged at the lower end of the T-shaped plate 42, and the telescopic end of the top extension cylinder 44 is hinged with a monitoring The measuring column 45 and the extension cylinder 44 can drive the monitoring column 45 to move in the up and down directions through the telescopic end, and the hinge direction of the monitoring column 45 is from front to back, so it can swing in the front and back directions. An arc-shaped plate 46 is provided at the lower end of the monitoring column 45, and the inner diameter of the arc-shaped plate 46 is provided with rolling balls 47 symmetrically distributed front and back. Distance sensors 48 are provided at the opposite ends of the two T-shaped plates 42, and a photoelectric sensor for detecting the rotation amplitude of the rolling ball 47 is also provided on the arc-shaped plate 46. The distance sensor 48 and the photoelectric sensor are both well-known technologies, and their uses are respectively used to detect the distance and the number of rotations of the rolling ball 47, so they will not be repeated in this implementation process.

[0050] The arc-shaped plate 46 can be pressed against the outer side of the cable. When the cable is stretched, the arc-shaped plate 46 is indirectly driven to be pressed against the outer side of the cable by the top extension cylinder 44. After the cable is stretched, its outer side will also be elongated. At this time, the stretched outer side of the cable will indirectly drive the T-shaped plate 42 to move toward the direction of the corresponding elastic member 43 through the arc-shaped plate 46 to compress the elastic member 43. At this time, the distance sensor 48 monitors the distance moved between the other T-shaped plate 42 and the T-shaped plate 42 to judge the tensile performance of the cable; when the cable is subjected to a torsion test, its outer side surface will also be synchronously twisted, and the twisting of the outer side of the cable will drive the rolling ball 47 on the inner wall of the arc-shaped plate 46 to rotate. At this time, the photoelectric sensor detects the change of the ball, that is, whether the ball rotates, and the rotation amplitude of the ball, to record the torsion of the outer side of the cable, so that the staff can know the test data of the cable in detail. Similarly, the arc-shaped plate 46 can also be driven by the top extension cylinder 44 to push the cable to bend, and detect whether the bending degree of the cable meets the standard, which further improves the applicability of the present invention.

[0051] Through the cooperation between the limiting plate 25 and the second airbag 219, the internal gas of the second airbag 219 enters the first airbag 213 evenly through the connecting tube. The sliding plate 211 can drive the clamping plate 212 to move in the fixed groove 29 when moving. When several clamping plates 212 are driven together by the sliding plate 211, they can be combined into a small circle. The first airbag 213 fits tightly against the cable surface. The internal air pressure of the first airbag 213 increases and pressure is applied to the cable surface. The greater the pressure, the greater the friction, which can prevent the cable from falling off. At the same time, the clamping of the first airbag 213 can ensure that the cable surface is not damaged, thereby improving the accuracy of the cable detection results. The clamping plate 212 indirectly applies a pulling force to the cable, so that the cable is stretched, thereby performing a tensile test.

[0052] Embodiment 2

[0053] like Fig.10 and Fig.11 As shown, on the basis of the above embodiment, in order to provide sufficient torque for the screw rod 13 to rotate, so that the clamping assembly 2 can have sufficient power to stretch and torsion test the cable, and realize that the stretching and torsion tests can be carried out simultaneously, the pushing assembly 5 is arranged on the outer wall of the side plate 12, and the pushing assembly 5 includes a pushing cylinder 50. The bottom of the pushing cylinder 50 is fixedly connected to the top of the base plate 1 through a cylinder seat, which is used to drive the cable to move. The telescopic end of the pushing cylinder 50 is provided with a driving rack 51. One end of the screw rod 13 passes through the corresponding side plate 12 and is provided with a driving gear 52 meshing with the driving rack 51 on the outside. The pushing cylinder 50 can drive the driving rack 51 to move in the up and down directions through the pushing end. When the driving rack 51 moves, it can be driven by the driving gear 5 2 drives the screw rod 13 to rotate, so that the screw rod 13 can drive the clamping assembly 2 to move, and at the same time avoids the situation that the existing technical solution is directly connected to the motor, resulting in insufficient torque and inability to stretch the cable. The other end of the screw rod 13 and one end of the rotating shaft 37 also pass through the corresponding side plate 12 and the support block 36 and are sleeved with mutually meshing transmission gears 53 on the outside thereof. When the screw rod 13 rotates, it can drive the corresponding transmission gear 53 to rotate. Since the two transmission gears 53 are in a meshing state with each other, the transmission gear 53 at the lower end will also be driven and drive the corresponding rotating shaft 37 to rotate, so that the rotating shaft 37 can indirectly drive the rotating plate 23 to rotate, so that when the clamping assembly 2 stretches the cable, the cable can also be subjected to a torsion test synchronously.

[0054] like Fig.10 and Fig.11As shown, the transmission gear 53 at the lower end is slidably connected with the rotating shaft 37. In order to be able to adjust whether the tensile test and the torsion test are performed simultaneously or not, an adjustment component 6 for driving the transmission gear 53 to slide is provided on the transmission gear 53. The adjustment component 6 includes a driving groove 60, which is provided on the transmission gear 53. A driving key 61 located in the driving groove 60 is provided on the outer side of the rotating shaft 37. The transmission gear 53 can slide on the outer side of the rotating shaft 37. When the rotating shaft 37 rotates, the corresponding transmission gear 53 can be driven to rotate through the driving key 61 and the driving groove 60, so that the screw rod 13 can indirectly drive the rotating shaft 37 to rotate, that is, at this time, the clamping component 2 can synchronously drive the cable to stretch and twist. The side plate 12 is provided with a locking plate 62 corresponding to the teeth on the outer side of the transmission gear 53, and the lower transmission gear 53 is also provided with an adjusting handle 63. If there is no need to perform a twisting test on the cable, the corresponding transmission gear 53 can be pushed toward the side plate 12 so that the two transmission gears 53 are no longer meshed. When the transmission gear 53 at the lower end is pushed to be in contact with the side plate 12, the locking plate 62 can now contact with the teeth on the transmission gear 53, and the transmission gear 53 is limited by the teeth on the transmission gear 53 to prevent it from rotating accidentally, thereby indirectly limiting the rotating plate 23. When a twisting test is desired, the corresponding transmission gear 53 can be pulled to the initial position by adjusting the handle 63 to continue to mesh with the transmission gear 53 at the upper end.

[0055] like Figure 1 As shown, in order to prevent the broken cable from splashing onto the workers and endangering their safety when the cable is tested, a protection component 7 is provided between the side panels 12 at both ends. The protection component 7 includes an arc frame plate 70, which is provided between the side panels 12 on both sides. The two side panels 12 can support and limit the arc frame plate 70. An arc slide plate 71 is also slidably provided in the arc frame plate 70. The arc slide plate 71 can slide in the arc frame plate 70. The arc slide plate 71 and the outer side of the arc frame plate 70 are provided with rubber strips to increase friction. The rubber strips can This allows the curved slide 71 to slide slowly inside the curved frame plate 70 to prevent the curved frame plate 70 from suddenly covering and injuring the staff, and when no external force is applied to the curved slide 71, the curved slide 71 can be limited on the curved frame plate 70 by the rubber strip. A pulling handle 72 is also provided at one end of the curved slide 71 located outside the curved frame plate 70. When the cable needs to be tested after being clamped by the clamping assembly 2, the curved slide 71 is pulled down by pulling the handle 72 to cover the clamping assembly 2 and the cable clamped therein, to prevent the cable from breaking during testing and splashing onto the staff.

[0056] By means of the monitoring component 4, the tensile and torsion degrees of the cable can be monitored in real time when the cable is subjected to tensile and torsion tests, so that the staff can obtain detailed data of the cable test. At the same time, the monitoring component 4 can also be used to resist the cable to implement a bending test of the cable, further increasing the applicability of the present invention.

[0057] Embodiment 3

[0058] Based on the above embodiments, the present invention further provides a cable structure strength detection method, comprising the following steps:

[0059] S1, cable clamping: the cable to be tested is placed between the rotating plates 23, and then the two ends of the cable are clamped by the clamping assembly 2 respectively, and the cable is kept in a taut state.

[0060] S2, tensile test: after the cable is clamped by the clamping assembly 2, the screw rod 13 drives the clamping assembly 2 to operate, and the two rotating plates 23 in the clamping assembly 2 can move in opposite directions to stretch the cable. At this time, the stretching degree of the cable is recorded by the monitoring assembly 4.

[0061] S3, twisting test: when the cable is stretched, the driving component 3 drives the rotating plate 23 on one side to rotate, that is, the clamping component 2 on one side is rotated, and the rotating clamping component 2 on one side can drive the cable to twist, thereby achieving the twisting test effect. When the cable is twisted, the monitoring component 4 records the twisting degree of the cable.

[0062] S4, tight test: the monitoring component 4 contacts the outside of the cable, pushing the outer side of the cable to bend, and testing the bending resistance of the cable.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
