Description

Technical Field

[0001] This invention relates to the field of power testing equipment technology, and in particular to an X-ray inspection device and method for the crimping area of ​​tension clamps in transmission lines. Background Technology

[0002] During the operation of overhead transmission lines, crimped tension clamps serve the dual function of conducting current and bearing the full tension of the conductor. Substandard crimping quality is a significant contributing factor to line breakage faults; therefore, quality inspection of the crimped area of ​​tension clamps is crucial for ensuring reliable line operation. Currently, mainstream inspection methods mainly include post-crimping dimensional inspection, grip strength testing, and X-ray inspection, each with its own limitations. External dimension inspection can only reflect the external shape of the crimping area and cannot reveal the actual crimping state inside the crimping tube; Grip strength testing is a destructive test that can only be used to sample and predict the quality of products in the same batch before installation. It cannot be used to conduct a comprehensive and accurate qualitative assessment of the quality of untested products and products in operation. X-ray inspection, as a non-destructive testing technology, has advantages such as intuitive inspection, accurate results, and no damage to conductors and fittings. However, this method has problems such as complex system structure, large equipment size and weight, poor convenience of tower operation, and radiation hazards to inspection personnel.

[0003] In recent years, with the development of UAV (Unmanned Aerial Vehicle) maintenance technology for power transmission lines, the application of UAVs equipped with X-ray inspection devices in the inspection of tension clamp crimping quality has gradually expanded, but it is still currently limited to single-conductor scenarios. In actual operation and maintenance, tension clamps for four- or more split conductors often suffer from obstruction by equipotential rings, adjacent sub-conductors, etc., which significantly restricts the installation position and space of the X-ray imaging board. For example, the "X-ray Flaw Detection Imaging Board End Mechanism for Single-Split Lines" disclosed in Chinese Patent CN222439425U improves the stability of single-split line inspection by optimizing the imaging board structure and has protection capabilities in complex environments, but it is only suitable for single cable inspection, and the inspection process relies excessively on manual adjustment, resulting in low work efficiency.

[0004] In summary, there is still a technological gap in the development of simple and efficient testing equipment for tension clamps in four-split and more split conductors. Summary of the Invention

The present invention provides an X-ray inspection device and method for the tension clamp crimping area of ​​a transmission line. An X-ray transmitter is driven to rotate via a rotating mechanism, allowing adjustment of its orientation. A first linear drive mechanism drives the inspection plate to move to the inside or outside of a sub-conductor. A second linear mechanism drives the inspection plate to rotate, adjusting its alignment with the X-ray transmitter to be parallel or perpendicular. This allows the X-ray transmitter to irradiate the tension clamp crimping area on any sub-conductor of a multi-split conductor with X-rays. The inspection plate can be moved to the outside of any sub-conductor to receive X-rays, enabling X-ray inspection of any sub-conductor. It allows for continuous inspection of the tension clamp crimping areas on each sub-conductor of a multi-split conductor, thus fully utilizing the space at the center of the multi-split conductor, solving the problem of limited X-ray inspection space, reducing inspection time, and improving equipment inspection efficiency.

[0017] 2. The present invention provides an X-ray inspection device and method for the crimping area of ​​a tension clamp in a transmission line. By cooperating with an auxiliary support mechanism and a traveling mechanism, the traveling mechanism can travel along one sub-conductor of a multi-split conductor while the auxiliary support mechanism can adaptively adjust and slide on another sub-conductor of the multi-split conductor. This improves the stability of the traveling mechanism during its movement, thereby enhancing the inspection stability of the equipment and improving the inspection accuracy.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Please refer to Figure 1 and 2 The present invention provides an X-ray inspection device for the crimping area of ​​tension clamps in transmission lines, which is applied to the inspection of the crimping area of ​​tension clamps in multi-split conductors such as four-split, six-split, and eight-split conductors. It mainly includes a housing 1, a traveling mechanism 2, a rotating mechanism 3, and an inspection component 4.

[0026] The housing 1 can be lifted by a drone to transport the X-ray inspection device for the tension clamp crimping area of ​​the transmission line above the multi-split conductor. In this embodiment, the housing 1 has a handle on its top, allowing the drone to lift it. The shape of the housing 1 can be flexibly set according to the actual application scenario, generally set to a symmetrical shape, such as the approximately rectangular shape of the housing 1 in this embodiment.

[0027] Please refer to Figure 3The housing 1 is equipped with a power supply 101 and a signal transmitter 102. The power supply 101 can be a rechargeable battery, used to power the walking mechanism 2, the rotating mechanism 3, and the detection component 4. The signal transmitter 102 connects the walking mechanism 2, the rotating mechanism 3, and the detection component 4, and is used for wireless communication with the UAV. The UAV can transmit control commands to the signal transmitter 102 to control the operation of the walking mechanism 2, the rotating mechanism 3, and the detection component 4, and obtain X-ray images detected by the detection component 4 through the signal transmitter 102. Considering the ventilation and heat dissipation of the electronic components inside the housing 1, a ventilation hole 103 can be provided on one side of the housing 1.

[0028] Please continue to refer to this. Figure 3 The walking mechanism 2 is located at the bottom of the housing 1, allowing the housing 1 to move along one of the sub-conductors of the multi-split conductor. The walking mechanism 2 is supported on the sub-conductor and can drive the housing 1 to move along the sub-conductor, so that the detection component 4 reaches the target position corresponding to the tension clamp to be tested.

[0029] Specifically, the walking mechanism 2 includes at least two drive wheels and at least two movable clamping members. Each drive wheel is located at the bottom of the housing 1 and is on the same straight line. The number of movable clamping members is the same as the number of drive wheels, and the specific number can be flexibly set according to the specifications and dimensions of the housing 1. For example, in this embodiment, the number of movable clamping members and the number of drive wheels are both two.

[0030] Each drive wheel includes a third motor 201 and a roller 202 connected to the third motor 201. The third motor 201 is mounted on the bottom of the housing 1 via a motor bracket 203. The output shaft of the third motor 201 is horizontally positioned, extends outward, and connects to the roller 202. Thus, the third motor 201 can drive the roller 202 to rotate.

[0031] Each movable clamping member is correspondingly disposed on the periphery of a corresponding drive wheel. Each movable clamping member includes a third linear drive mechanism 204, a first connecting rod 205, a second connecting rod 206, and a clamping wheel 207. The first connecting rod 205 is arc-shaped, with one end rotatably connected to the housing 1 and the other end connected to the clamping wheel 207, which is located below the drive wheel. One end of the second connecting rod 206 is rotatably connected to the third linear drive mechanism 204, and the other end is rotatably connected to the middle of the first connecting rod 205. The third linear drive mechanism 204 is rotatably connected to the housing 1. Here, the third linear drive mechanism 204 can be an electric push rod, with its upper end rotatably connected to the bottom of the housing 1 and its lower end rotatably connected to one end of the second connecting rod 206. The first connecting rod 205 has a through groove in its middle, and the other end of the second connecting rod 206 is inserted into the through groove and rotatably connected to the first connecting rod 205. The third linear drive mechanism 204 can drive the second connecting rod 206 to move, thereby driving the first connecting rod 205 to move, so that the clamping wheel 207 and the roller 202 clamp the sub-wire. In order to make the clamping wheel 207 and the roller 202 clamp the sub-wire more stably, the surfaces of the clamping wheel 207 and the roller 202 can be provided with V-shaped grooves for the surface of the sub-wire to be engaged.

[0032] The rotating mechanism 3 is mounted below the housing 1 via a column 307, and is generally located on the side of the housing 1 away from the drive wheel. Specifically, the column 307 is vertically arranged, with its upper end connected to the housing 1 and its lower end connected to the rotating mechanism 3.

[0033] Please refer to Figure 4 The detection component 4 includes an X-ray emitter 401, a detection plate 403, a cam 404, a support 402, a first linear drive mechanism 405, and a second linear drive mechanism 406. The rotation mechanism 3 is connected to the X-ray emitter 401. The first linear drive mechanism 405 is fixedly provided on one side of the X-ray emitter 401. The output end of the first linear drive mechanism 405 is connected to the support 402. The detection plate 403 is rotatably mounted on the support 402 and connected to the cam 404. The output end of the second linear drive mechanism 406 is connected to the cam 404.

[0034] Both the first linear drive mechanism 405 and the second linear drive mechanism 406 can be selected as electric push rods. The output end of the first linear drive mechanism 405 is vertically upward. The support 402 is elongated and horizontally positioned. The output end of the first linear drive mechanism 405 is fixedly connected to one end of the support 402. The detection plate 403 is approximately rectangular in shape. One end of a horizontal side of the detection plate 403 is rotatably connected to one end of the support 402 and fixedly connected to the wider end of the cam 404. One end of the second linear drive mechanism 406 is rotatably fixed to the other end of the support 402. The other end of the second linear drive mechanism 406 is the output end and is rotatably connected to the narrower end of the cam 404. Thus, the first linear drive mechanism 405 can drive the support 402 to move vertically along the sub-guide wire, thereby causing the detection plate 403 to move vertically along the sub-guide wire. The second linear motion can drive the cam 404 to rotate, thereby causing the detection plate 403 to rotate, so that the detection plate 403 is perpendicular or parallel to the X-ray emitter 401.

[0035] The rotating mechanism 3 is used to drive the X-ray emitter 401 to rotate about an axis parallel to the sub-conductor. Specifically, as shown... Figure 4 As shown, the rotating mechanism 3 includes a first motor 301, a base 302, and a first gear set. The base 302 is fixedly mounted on the lower end of the column 307. The first motor 301 is mounted on one end of the base 302, and the first gear set is mounted on the other end of the base 302. The output shaft of the first motor 301 is connected to the first gear set. The X-ray emitter 401 and the first linear drive mechanism 405 are mounted on the mounting plate 407, and the first gear set is connected to the mounting plate 407. The first motor 301 can drive the first driving gear 303 to rotate. The first driven gear 304 meshes with the first driving gear 303 to drive the mounting plate 407 to rotate, which in turn drives the X-ray emitter 401 to rotate, thereby realizing the rotation of the driven X-ray emitter 401 around an axis parallel to the sub-guide wire.

[0036] In some embodiments, the rotating mechanism 3 further includes an insert plate 305. The first gear set includes a first driving gear 303 and a first driven gear 304. The output shaft of the first motor 301 passes through the base 302 and is connected to the first driving gear 303. The base 302 has a slot near the end of the first driving gear 303. The insert plate 305 has an insert rod 306, which is slidably inserted into the slot. The axle of the first driven gear 304 passes through the insert plate 305 and is connected to the mounting plate 407. The first driving gear 303 meshes with the first driven gear 304. The detection component 4 is detachably mounted on the rotating mechanism 3 through the cooperation of the insert rod 306 and the slot.

[0037] like Figure 5 As shown, in some embodiments, the X-ray inspection device for the crimping area of ​​a transmission line tension clamp according to the present invention further includes a transverse movement mechanism 5. The transverse movement mechanism 5 includes a second motor 502, a second gear, a rack 504, and a moving block 501. The moving block 501 is slidably disposed on the housing 1 and connected to the upper end of the column 307. The rack 504 is disposed on the housing 1. The second gear is rotatably mounted on the moving base and meshes with the rack 504. The second motor 502 is connected to the second gear and is used to drive the moving block 501 to move the column 307 along the length direction of the sub-conductor.

[0038] More specifically, the bottom of the housing 1 is provided with a sliding seat 507, the bottom of the sliding seat 507 is provided with a slide rail 506, the moving block 501 is disposed around the sliding seat 507, the bottom of the sliding seat 507 is provided with a groove, the groove is fitted with the slide rail 506 and can slide, the other side of the sliding seat 507 is provided with a mounting groove 505, the rack 504 is disposed in the mounting groove 505, and the second gear is inserted into the mounting groove 505 and meshes with the rack 504.

[0039] Thus, the transverse mechanism 5 drives the second gear to roll along the rack 504 via the second motor 502, causing the moving block 501 to move along the length of the sub-conductor, thereby adjusting the position of the detection component 4 along the length of the sub-conductor, that is, adjusting the detection position of the X-ray emitter 401 and the detection plate 403.

[0040] like Figure 6As shown, in some embodiments, the X-ray inspection device for the crimping area of ​​a transmission line tension clamp according to the present invention further includes an auxiliary support mechanism 6. The auxiliary support mechanism 6 is disposed on the side of the housing 1 away from the wheel. The auxiliary support mechanism 6 includes a rotating seat 601, a fourth motor 605, a third gear 503 group, a third connecting rod 602, a crank rod 603, and a support wheel 604. The rotating seat 601 is rotatably disposed on the housing 1. The fourth motor 605 is connected to the third gear 503 group. The third gear 503 group is connected to the rotating seat 601 to drive the rotating seat 601 to rotate. One end of the third connecting rod 602 is slidably disposed on the rotating seat 601, and the other end is rotatably connected to the middle part of the crank rod 603. One end of the crank rod 603 is rotatably connected to the rotating seat 601, and the other end is connected to the support wheel 604, so that the support wheel 604 can be supported on another sub-conductor. Of the two sub-wires at the top of the multiple split wires, one sub-wire is supported by the roller 202 and the other is supported by the support wheel 604.

[0041] The third gear set 503 described here includes a meshing third driving gear 606 and a third driven gear 607. The third driving gear 606 is connected to the output end of the fourth motor 605, and the third driven gear 607 is connected to the rotating base 601. A V-groove can be provided on the surface of the support wheel 604 to allow it to be more stably supported on the sub-conductor. Rotation of the rotating base 601 can drive the support wheel 604 to deflect upwards or downwards, adjusting its height. When there is a height difference between the two sub-conductors at the top of the multi-split conductor, this satisfies the requirement for stable movement of the traveling mechanism 2.

[0042] Furthermore, a horizontally arranged groove 608 can be provided on the rotating seat 601, and one end of the third connecting rod 602 is rotatably connected to a slider 609, which is slidably disposed within the groove 608. A locking bolt 610 can also be provided on the slider 609, which passes through the slider 609 and abuts against the groove 608, thereby locking the third connecting rod 602. In this way, by adjusting the position of the slider 609, the third connecting rod 602 can push and pull the crank 603, causing the support wheel 604 to move closer to or further away from the roller 202, thus adjusting the distance between the support wheel 604 and the roller 202. This ensures stable movement of the traveling mechanism 2 when the horizontal distance between the two sub-conductors at the top of the multi-split conductor changes.

[0043] Furthermore, embodiments of the present invention also provide an X-ray inspection method for the crimped area of ​​a tension clamp in a transmission line, using the aforementioned X-ray inspection device for the crimped area of ​​a tension clamp in a transmission line, and including the following steps: S1. The X-ray inspection device for the crimping area of ​​the tension clamp of the transmission line is transported by a drone, and the traveling mechanism 2 is supported on a sub-conductor at the top of the multi-split conductor. The traveling mechanism 2 drives the X-ray inspection device for the crimping area of ​​the tension clamp of the transmission line to travel on a sub-conductor at the top of the multi-split conductor to the target position corresponding to the tension clamp to be inspected. The inspection component 4 extends between the sub-conductors of the multi-split conductor.

[0044] In this embodiment, the tension clamp crimping area on the six-split conductor is inspected. The six-split conductor consists of six sub-conductors arranged in a regular hexagon, and each sub-conductor is equipped with a tension clamp to be inspected. The UAV pulls the top of the housing 1 and lifts the housing 1 above the six-split conductor, so that each of the drive wheels is supported on one of the top sub-conductors. The clamping wheel 207 is driven by the third linear drive mechanism 204 to fit against the bottom of the sub-conductor and clamp the sub-conductor in cooperation with the drive wheel. The support wheel 604 is supported on another sub-conductor at the top, and the detection component 4 extends into the interior of the six-split conductor. The support wheel 604 can be driven to deflect upward or downward by the fourth motor 605, or the position of the support wheel 604 can be adjusted by adjusting the position of the slider 609, so that the support wheel 604 can be stably supported on the sub-conductor.

[0045] Then, the walking mechanism 2 drives the housing 1 to walk on the sub-conductor, and the detection component 4 moves forward in the space between each sub-conductor of the six-split conductor. When the detection component 4 approaches the tension clamp to be tested, it reaches the target position.

[0046] S2. The X-ray emitter 401 is driven to rotate towards the tension clamp to be tested on a sub-conductor by the rotating mechanism 3; the detection plate 403 is driven to move outward along the vertical direction of the sub-conductor by the first linear drive mechanism 405, so that the detection plate 403 moves to the outside of the sub-conductor; the detection plate 403 is driven to rotate to be perpendicular to the X-ray emitter 401 by the second linear drive mechanism 406; the detection plate 403 is driven to move inward along the vertical direction of the sub-conductor by the first linear drive mechanism 405, so that the detection plate 403 is in contact with the sub-conductor; the tension clamp to be tested is X-ray tested by the X-ray emitter 401.

[0047] S3. Drive the detection plate 403 to rotate parallel to the X-ray emitter 401 by the second linear drive mechanism 406, and drive the detection plate 403 to move inward along the vertical direction of the sub-conductor by the first linear drive mechanism 405, so that the detection plate 403 retracts between the sub-conductors of the multi-split conductor. At this time, the detection plate 403 and the detection assembly 4 return to the sub-conductors of the six-split conductor. S4. Repeat steps S2 and S3 multiple times to perform X-ray inspection on the tension clamps to be inspected on the other sub-conductors of the multi-split conductor.

[0048] Steps S2 and S3 are repeated five times. The X-ray emitter 401 is driven to rotate sequentially towards the tension clamps to be tested on the other sub-conductors via the rotating mechanism 3. For each tension clamp to be tested on the sub-conductor, X-ray inspection is performed on the tension clamp to be tested according to the method in step S2. In this way, X-ray inspection is performed on the tension clamps on the other five sub-conductors of the six-split conductor, and finally X-ray images of the crimping areas of the tension clamps of the six sub-conductors of the six-split conductor are obtained. The X-ray images are processed to identify whether there are defects in the crimping areas of the tension clamps on each sub-conductor.
