Description

Technical Field

[0001] This invention belongs to the field of wire rope flaw detection technology, and in particular relates to a wire rope testing device for power transmission lines. Background Technology

[0002] Anti-torsion wire ropes play a crucial role as a "stabilizing core carrier" in power traction (primarily referring to conductor / optical cable traction, equipment hoisting, and tensioning during power transmission line construction and maintenance). Their core value lies in addressing the rotational hazards associated with ordinary wire rope traction through their anti-torsion properties, ensuring the safety, accuracy, and efficiency of power line construction. Typical applications of anti-torsion wire ropes in power traction include: power transmission line stringing (conductor / ground wire / optical cable traction), tensioning, wire tightening operations, substation equipment hoisting, and high-altitude maintenance traction.

[0003] Existing equipment for flaw detection of anti-torsion wire ropes is ineffective in the initial cleaning process, failing to thoroughly clean the ropes and thus affecting the accuracy of flaw detection. Therefore, it is essential to find a way to effectively and thoroughly clean anti-torsion wire ropes.

[0004] Existing flaw detection equipment mostly uses dynamic scanning flaw detection when inspecting cleaned anti-torsion wire ropes, where the wire rope moves while the detector remains stationary. However, dynamic scanning detection has lower accuracy or precision than static scanning. Therefore, it is necessary to realize static scanning detection of moving anti-torsion wire ropes.

[0005] In addition, existing flaw detection equipment is not effective for grease coating of anti-torsion wire ropes and consumes a lot of grease, resulting in high maintenance costs.

[0006] This invention designs a steel wire rope detection device for power transmission lines to solve the above problems. Summary of the Invention

[0007] Therefore, it is necessary to address the problems existing in the current equipment used for anti-torsion wire rope flaw detection and provide a wire rope detection device for power transmission lines. This device achieves the purpose of effective internal and external cleaning, accurate static flaw detection, and uniform grease coating and maintenance of the anti-torsion wire rope through cleaning components, detection components, first maintenance components, and second maintenance components.

[0008] The above objectives are achieved through the following technical solutions: A wire rope testing device for power transmission lines, used for flaw detection and grease coating maintenance of anti-torsion wire ropes, comprising: A cleaning assembly is used to effectively clean dirt from the surface and crevices of an anti-torsion wire rope.

The cleaning assembly also has a structural feature that allows the anti-torsion wire rope to be laterally inserted along its radial direction.

[0009] The detection component is used to perform flaw detection on anti-torsion wire rope by means of magnetic flux leakage detection. The detection component has the structural feature of static scanning detection of anti-torsion wire rope with axial movement.

[0010] The first maintenance component is used for applying a low-cost, single-line grease along the axial direction to the surface of the anti-torsion wire rope.

[0025] 4. The cleaning component, guiding component, detection component, first maintenance component and second maintenance component in this invention can enable the anti-torsion wire rope to be inserted laterally along its radial direction, thereby improving the installation efficiency of the anti-torsion wire rope.

[0026] 5. The first maintenance component in this invention uses the movement of the anti-twist steel wire rope to continuously squeeze and apply grease onto the anti-twist steel wire rope, which consumes less energy. Attached Figure Description

[0045] The cleaning component 400 of this invention can sequentially clean the anti-torsion wire rope 801 three times through the first cleaning structure 409, the second cleaning structure 436, and the third cleaning structure 460, thereby effectively cleaning both the exterior and interior of the anti-torsion wire rope 801. The detection component 500 of this invention utilizes the movement of the anti-torsion wire rope 801 to drive two detection wheels 513 distributed circumferentially at 180 degrees to move at the same linear velocity as the anti-torsion wire rope 801. This allows the Hall sensors 514 on the two detection wheels 513 to perform static flaw detection on the moving anti-torsion wire rope 801. Simultaneously, the staggered distribution of the Hall sensors 514 on the two detection wheels 513 avoids missed detections of the anti-torsion wire rope 801, thereby improving the accuracy and efficiency of flaw detection. The first maintenance component 600 and the second maintenance component 700 in this invention can achieve all-round grease coating and maintenance of the anti-torsion wire rope 801, and can make the grease applied to the anti-torsion wire rope 801 uniform and thin, saving grease and reducing maintenance costs. The cleaning component 400, guiding component 200, detection component 500, first maintenance component 600 and second maintenance component 700 in this invention can enable the anti-torsion wire rope 801 to be inserted laterally along its radial direction, thereby improving the installation efficiency of the anti-torsion wire rope 801.

[0046] The operation flow of this invention is as follows: In the initial state, there is a large gap between the upper clamping wheel 207 and the lower clamping wheel 203 in the guide assembly 200. The three first cleaning wheels 421 in each first cleaning structure 409 abut against each other under the action of the corresponding first spring 419. Two of the first cleaning wheels 421 in the first cleaning structure 409 are located on both sides of the notch in the cylinder 401, and the notch of the first toothed ring 411 and the first toothed rack 413 are opposite to the notch in the cylinder 401. The notch of the fourth ring 468 in the third cleaning structure 460 is opposite to the notch of the third ring 461. The two magnets 503 in the detection assembly 500 press against each other to form a circular receiving groove 504 that facilitates the passage of the anti-twist steel wire rope 801. The two second positioning wheels 511 press against each other, and the third spring 505 and the fourth spring 507 are in a compressed state. The edge of the third positioning wheel 617 in the first maintenance assembly 600 is tangent to the axis of the cylinder 401. The two scrapers 717 in the second maintenance component 700 press against each other under the action of the second spiral spring 722, and the notch of the sixth ring 704 is opposite to the notch of the fifth ring 702.

[0047] When the anti-torsion wire rope 801 needs to be inspected, the delivery reel 101 with the anti-torsion wire rope 801 wound on it and the empty winding reel 301 are installed on the first support 102 and the third support 302 respectively by a crane. During the process of pulling the anti-torsion wire rope 801 from the delivery reel 101 to the winding reel 301, the anti-torsion wire rope 801 is placed from the side into the cleaning component 400, the guiding component 200, the detection component 500, the first maintenance component 600 and the second maintenance component 700.

[0048] After the anti-twist wire rope 801 is placed sideways between the upper clamping wheel 207 and the lower clamping wheel 203 of the guide assembly 200, the first crank 206 is cranked. The first crank 206 drives the upper clamping wheel 207 to press and clamp the anti-twist wire rope 801 against the lower clamping wheel 203 through the screw 205 and the slide 204. The entire guide assembly 200 straightens and guides the anti-twist wire rope 801.

[0049] When the anti-twist wire rope 801 is placed into the first cleaning structure 409 of the cleaning assembly 400, the first rack 413 of the first cleaning structure 409 swings outward to open the notch of the first gear ring 411. After the anti-twist wire rope 801 is placed into the first gear ring 411, the first rack 413 swings back to close the notch of the first gear ring 411 under the action of the first spiral spring 415. The two first cleaning wheels 421 distributed on both sides of the notch of the cylinder 401 overcome the compression of the anti-twist wire rope 801 and move along the corresponding first spring 419. The cylinder 401 moves radially away from the axis of the cylinder 401 and does not obstruct the entry of the anti-twist wire rope 801. When the anti-twist wire rope 801 enters between the three first cleaning wheels 421, the two first cleaning wheels 421 distributed on both sides of the notch of the cylinder 401 are reset under the action of the corresponding first spring 419. Under the action of the anti-twist wire rope 801, the three first cleaning wheels 421 will all generate a certain displacement in the radial direction away from the axis of the cylinder 401 and form a radial pressure state on the anti-twist wire rope 801.

[0050] When the anti-torsion wire rope 801 is placed into the second cleaning structure 436 of the cleaning assembly 400, the second crank 459 is cranked. The second crank 459, through the eleventh gear 458, tenth gear 457, fifth shaft 456, ninth gear 455, third rack 453, eighth gear 452, fourth shaft 451, and seventh gear 450, drives the four second racks 437 in the two second cleaning structures 436 to move radially away from the axis of the cylinder 401 by a certain amount, compressing the second spring 438. Each second cleaning structure 436... The two second racks 437 in 6 drive the two first positioning wheels 441 and the two second cleaning wheels 443 to move in opposite directions and separate. After the anti-twist wire rope 801 is radially inserted from the notch of the cylinder 401 between the two first positioning wheels 441 and the two second cleaning wheels 443 in the second cleaning structure 436, the first positioning wheels 441 and the second cleaning wheels 443 in the two second cleaning structures 436 clamp the anti-twist wire rope 801 under the action of the second spring 438, and the cleaning wire 446 on the second cleaning wheel 443 is inserted into the gap of the anti-twist wire rope 801.

[0051] When the anti-twist wire rope 801 is placed into the third cleaning structure 460 of the cleaning assembly 400, the first baffle 464 and the second baffle 472 are moved to open the notch on the third ring 461 and the notch on the fourth ring 468. After the anti-twist wire rope 801 is inserted through the rings on the third ring 461 and the fourth ring 468, the first baffle 464 and the second baffle 472 close the notch on the third ring 461 and the fourth ring 468 under the action of the first leaf spring 465 and the second leaf spring 473, respectively.

[0052] When the anti-torsion wire rope 801 is placed into the detection assembly 500, the third crank 522 is cranked. The third crank 522, through the sixteenth gear 521, fifteenth gear 520, seventh shaft 519, fourteenth gear 518, thirteenth gear 517, sixth shaft 516, twelfth gear 515 and fourth rack 502, drives the two magnets 503 to separate and simultaneously drives the two second positioning wheels 511 to separate, and the third spring 505 is further compressed. After the anti-torsion wire rope 801 is placed in, the two magnets 503 press against each other again under the action of the third spring 505, and the anti-torsion wire rope 801 is located in the receiving groove 504 formed by the two magnets 503. The two second positioning wheels 511 form a radial clamp on the anti-torsion wire rope 801, and there is a gap between the Hall sensor 514 on the detection wheel 513 and the anti-torsion wire rope 801.

[0053] When the anti-torsion wire rope 801 is placed in the first maintenance component 600, the crossbar 616 is pushed upwards, causing the second guide rod 615 to retract into the fourth guide sleeve 613 and compress the fifth spring 614. The crossbar 616 drives the third positioning wheel 617 and the grease tube 605 to move synchronously, and the tenth rotating shaft 621 slides into the rotating sleeve 622 to retract. After the anti-torsion wire rope 801 is placed, the third positioning wheel 617 radially presses the anti-torsion wire rope 801 under the action of the fifth spring 614. The grease tube 605 has a small gap between its opening and the anti-torsion wire rope 801 to facilitate the application of grease to the anti-torsion wire rope 801.

[0054] When the anti-twist wire rope 801 is placed into the second maintenance component 700, the lever 720 is activated. The lever 720 drives the two scraper plates 717 to swing back and forth a certain distance through the thirteenth rotating shaft 721, the twenty-ninth gear 723, the thirtieth gear 724, the fourteenth rotating shaft 725, the thirty-first gear 726, the thirty-second gear 727, and the fifteenth rotating shaft 728, and compresses the second spiral spring 722 so that the steel wire rope can be placed between the two scraper plates 717. After the anti-twist wire rope 801 is placed between the two scraper plates 717 through the gaps of the fifth ring 702 and the sixth ring 704, the two scraper plates 717 clamp the anti-twist wire rope 801 under the action of the second spiral spring 722.

[0055] After the end of the anti-twist wire rope 801 is wound and fixed on the winding wheel, the first motor 303 is started to drive the winding disc 301 to rotate and to wind and pull the anti-twist wire rope 801.

[0056] During the axial movement of the anti-torsion wire rope 801, the second motor 435 is activated. The second motor 435 drives the first cleaning wheels 421 in the two first cleaning structures 409 to revolve around the anti-torsion wire rope 801. Simultaneously, the first gear 422 on the first wheel shaft 420 of each first cleaning wheel 421 drives the first cleaning wheel 421 to rotate under the action of the first gear ring 411 or the first rack 413. The first cleaning wheels 421, which revolve and rotate simultaneously, perform circumferential cleaning on the surface of the anti-torsion wire rope 801. The revolution and rotation of the first cleaning wheels 421 in the two first cleaning structures 409 are opposite, thereby preventing the anti-torsion wire rope 801 from twisting under the action of a single first cleaning structure 409. This ensures that the anti-torsion wire rope 801 does not twist after being separated from the first cleaning structure 409, thus preventing the cleaning wire 446 inserted into the gap of the anti-torsion wire rope 801 in the second cleaning structure 436 from getting stuck in the gap.

[0057] The four first positioning wheels 441 in the two second cleaning structures 436 rotate under the action of the anti-torsion wire rope 801. The first positioning wheels 441 drive the four second cleaning wheels 443 to rotate through the second wheel shaft 440, the fourth pulley 449, the second synchronous belt 448, the third pulley 447, and the third wheel shaft 442. The second cleaning wheels 443 drive the cleaning wires 446 on the wheel ring 445 to rotate in the same direction as the anti-torsion wire rope 801 through the ultrasonic vibrator 444. The linear velocity of the rotation of the cleaning wires 446 driven by the wheel ring 445 is equal to the speed of the anti-torsion wire rope 801, thereby avoiding relative motion between the cleaning wires 446 and the anti-torsion wire rope 801. This also prevents the cleaning wires 446 from getting stuck after being inserted into the gaps in the anti-torsion wire rope 801. The cleaning wires 446 inserted into the gaps in the anti-torsion wire rope 801 can separate the dirt in the gaps. The dirt cleaned off the surface and crevices of the anti-twist steel wire rope 801 falls to the bottom of the cylinder 401 and is discharged through the slag discharge trough 403.

[0058] The air pump 467 in the third cleaning structure 460 delivers air to the first annular cavity 462 of the third ring 461 via the air delivery pipe 466. The air entering the first annular cavity 462 enters the second annular cavity 469 of the fourth ring 468 via the connecting groove 463 and drives the fourth ring 468 to rotate under the action of the blade 470. The air entering the second annular cavity 469 blows and cleans the dirt remaining in the gaps and surface of the anti-twist steel wire rope 801 through the air nozzle 471 on the inner wall of the fourth ring 468.

[0059] Two magnets 503 in the detection assembly 500 energize the incoming anti-torsion wire rope 801. Two second positioning wheels 511 rotate under the action of the anti-torsion wire rope 801. These wheels, via corresponding fourth wheel shaft 510, sixth pulley 525, third synchronous belt 524, fifth pulley 523, and fifth wheel shaft 512, drive two detection wheels 513 to rotate. This ensures that the monitoring point of the cleaning wheel on the line connecting the centers of the two cleaning wheels remains stationary relative to the moving anti-torsion wire rope 801, thereby achieving static scanning detection of the moving anti-torsion wire rope 801 by the Hall sensors 514 on the two detection wheels 513, improving detection accuracy. Simultaneously, the gaps between the Hall sensors 514 on the lower detection wheel 513 and the corresponding two Hall sensors 514 on the upper detection wheel 513 are aligned, ensuring accurate and complete flaw detection of the anti-torsion wire rope 801.

[0060] The third positioning wheel 617 in the first maintenance component 600 rotates under the action of the anti-torsion wire rope 801. The third positioning wheel 617 drives the spiral blade 607 to apply grease from the hopper 608 into the extrusion cylinder 602 through the extrusion pipe 603, the corrugated pipe 604 and the grease application pipe 605 to the surface of the moving anti-torsion wire rope 801.

[0061] The two scrapers 717 in the second maintenance component 700 clamp the moving anti-twist wire rope 801 under the action of the second spiral spring 722, and rotate relative to the anti-twist wire rope 801 under the drive of the third motor 715. The two scrapers 717 axially and evenly apply the grease applied to the surface of the anti-twist wire rope 801. As the scrapers 717 apply the grease, excess grease will accumulate on the scrapers 717. The accumulated grease will return to the surface of the anti-twist wire rope 801 under the guidance of the corresponding recovery arc plate 719 and be evenly applied by the rotating scrapers 717.
