Description

Technical Field

[0001] The present invention relates to the technical field of high-altitude tension clamp X-ray detection, and in particular to a high-altitude tension clamp X-ray detection device, system and method. Background Art

[0002] The tension clamp is an important hardware used in the fields of overhead power transmission conductors, overhead communication sub-conductors, etc. Its main function is to fix the conductor (such as steel core aluminum stranded wire and other power transmission conductors or communication cables) on the tension insulator string, or to fix the split conductor on the tension transposition hardware. The internal sub-conductor detection of the tension clamp: using the method of ray detection, the distribution, shape and other characteristics of different grayscale areas in the collected image are used to determine whether there are defects in the internal sub-conductor, observe whether the image of the conductor part is continuous, whether there is a sudden thinning or interruption to determine whether there is a broken strand phenomenon, and check whether there is a gap or uneven grayscale distribution in the image inside the crimping tube to determine whether the connection is good.

[0003] However, since high-altitude tension clamps are usually installed at high places on power transmission conductors, inspectors need to work at high altitudes, which poses a risk of falling. In addition, since the detection equipment carries radiation risks, inspectors need to dodge after a single adjustment. When detecting multiple split lines, users need to make multiple reciprocating adjustments, which makes the operation difficult. In addition, the spacing between different numbers of split lines may not meet the penetration requirements of the imaging plate, resulting in the inability to perform X-ray detection on a large number of split lines.

[0039] See also Figures 1 to 8 The embodiment of the present invention also provides a high-altitude tension clamp X-ray detection system, including a drone and the above-mentioned device, wherein the body has a hoisting end connected to the drone.

In addition, the drone can be a separate unmanned drone, or the drone can be directly designed with wings to fly to high altitude for autonomous operation. Both methods are possible, and this embodiment does not limit this.

[0040] See also Figures 1 to 8, an embodiment of the present invention provides an X-ray detection method for a high-altitude tension clamp, which is used for the above-mentioned device, and includes the following steps: S1, using a drone to lift the body to the sub-conductor of the high-altitude tension clamp; S2, placing the walking component on the sub-conductor; S3, the walking component moves the X-ray detection component to a designated detection position; S4, using the locking component to lock the walking component on the sub-conductor to lock the position of the body; S5, after adjusting the detection posture of the X-ray detection component, the X-ray detection component is used to perform ray detection on the split line in the tension clamp. In this embodiment, a ground-to-air unmanned detection method is adopted to remotely detect the split line in the tension clamp, and at the same time, the detection requirements for multiple split lines are realized through flexible walking and locking components, and the convenience and stability of the detection process are improved.

[0041] Preferably, in step S5, the X-ray detection component can be adjusted to an accurate radiation imaging angle and position by using a positioning component and a calibration component in combination.

[0042] The following is the detailed detection method:

[0043] Step 1: The detection device is first hoisted on the surface of the split line using a large load-bearing drone, so that the surfaces of the four hanging wheels 62 are in contact with the surface of the split line, and then the fourth stepper motor 65 is turned on. Under the meshing transmission of the two bevel gears 66, the fourth stepper motor 65 drives the driving rod 64 to rotate. During the rotation of the driving rod 64, the hanging wheels 62 at the front and rear ends thereof are driven to rotate. During the rotation of the hanging wheels 62, the carbon fiber base 1 and the carbon fiber hanging plate 2 are driven to move toward the tension clamp until they reach the detection position. Then, the second electric telescopic rod 73 opens and pulls the lifting plate 74 downward. The lifting plate 74 drives the two racks 75 to slide downward during the downward movement. Due to the meshing transmission of the racks 75 and the flip gear 76, the two flip gears 76 rotate, thereby causing the flip arm 71 to rotate. During the rotation of the flip arm 71, the extrusion block 72 is flipped, so that the top of the extrusion block 72 is pressed against the surface of the tension clamp, so that the extrusion block 72 and the hanging wheel 62 clamp and position the tension clamp, thereby ensuring the accuracy of the detection device during the detection process or the detection position;

[0044] Step 2, then detect the internal split lines of different tension clamps in turn. During the detection, the second stepper motor 501 is turned on and drives the screw rod 502 to rotate. During the rotation, the screw rod 502 pushes the encoder 503 through its surface thread, so that the encoder 503 drives the lifting frame 32 to slide downward in the inner cavity of the fixed frame 31, so that the lifting frame 32 drives the X-ray imaging plate 35 to move downward, and at the same time, the X-ray machine 33 moves downward. The height adjustment algorithm is used here: define the pitch unit: mmP=5, define the number of rotations n=10, calculate the screw advancement distance unit: mmL=P*n, take eight split lines as an example: the required advancement value is at least the spacing value L=600mm between two adjacent split lines, P=5, then the screw rod 502 rotates n=600 / 5=120, until the X-ray imaging plate 35 reaches the bottom of the tension clamp, the first electric telescopic rod 4 1. Turn on and push the oblique push piece 42, so that the oblique push piece 42 rotates and drives the x-ray imaging plate 35 and the x-ray imaging plate 35 to flip. Here, the angle adjustment algorithm is adopted: the number of encoder pulses / circle n=1000, the number of counted pulses m, the rotation angle Θ, Θ=m / n*360: take the eight-split line as an example: the distance angle between the two lines of the eight-split line is 45°, considering that the x-ray imaging plate 35 has a certain width, the rotation angle should be ≦45°, take 45° as an example: the number of encoder 503 counted pulses m=360 / 1000*45=125, and the number of encoder 503 counted pulses is 125 pulse signals. At this time, the x-ray machine 33 is turned on, and with the cooperation of the x-ray imaging plate 35, the tension clamp is radiographed, and the shooting content is transmitted to the ground, and the content is presented as an image through the PC end, so that the detection personnel can check the connection status of the split line in the tension clamp;

[0045] Step 3: When the user detects the separation lines at different positions, the third stepper motor 505 is turned on and drives the second rotating rod 506 to rotate. During the rotation process, the second rotating rod 506 drives the worm 507 to rotate through the strip insert 512 and the synchronous slide groove 513. During the rotation process, the worm 507 drives the worm wheel 508 meshing with it to rotate in the inner cavity of the protective shell 504. During the rotation process, the worm wheel 508 drives the third rotating rod 509 to rotate, so that the transmission gear 510 rotates, and drives the force gear 511 meshing with it to rotate. Driven by the force gear 511, The lifting frame 32 rotates in the inner cavity of the fixed frame 31, and the lifting frame 32 drives the X-ray imaging plate 35 to rotate during the rotation process. The lifting frame 32 drives the output end of the encoder 503 to rotate and generate a pulse signal. At the same time, the number of pulses obtained is counted by its internal counting chip. After reaching the set value, an in-position signal is issued, and the third stepping motor 505 is controlled to stop running through the motor controller, so that the X-ray imaging plate 35 reaches the other side of the tension clamp that needs to be detected. Through the cooperation of the X-ray machine 33 and the X-ray imaging plate 35, the split line in the tension clamp is subjected to X-ray detection;

[0046] Step 4. According to the detection requirements for tension clamps at different positions, after the x-ray imaging plate 35 is in place, the first stepper motor 46 is turned on and drives the first rotating rod 45 to rotate. During the rotation, the first rotating rod 45 drives the two driving gears 47 to rotate. Due to the meshing transmission of the driving gear 47 and the rack 48, the x-ray imaging plate 35 slides back and forth. During the displacement of the x-ray imaging plate 35 back and forth, the limiting slide groove 44 slides on the surface of the limiting guide rail 43, providing a sufficient presentation area for the x-ray machine 33. At the same time, the two adjacent tension clamps can be imaged in sequence by moving the x-ray imaging plate 35, avoiding the need to adjust the imaging position through the lifting frame 32 multiple times.

[0047] To sum up: the high-altitude tension clamp X-ray detection device, system and method, through the coordinated use of the carbon fiber hanging plate 2 and the walking component 6, moves the carbon fiber base 1 to the specified detection position, and then locks and fixes the detection position through the locking component 7, and then adjusts to the accurate X-ray imaging angle and position through the coordinated use of the adjustment component 4 and the calibration component 5, and finally, under the action of the detection component 3, the split line in the tension clamp is subjected to X-ray detection, which can achieve the purpose of unmanned remote detection at high altitude, flexible adaptation to the detection needs of multiple split lines and convenient and stable detection process.
