Description

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

[0002] Nowadays, every household cannot do without electrical equipment, and cables for transmitting electrical energy can often be seen outdoors. Cables are a device used for power or signal transmission. They are usually made up of several or several groups of wires twisted together, and the wires are insulated from each other. The outer surface of the cable is also covered with a highly insulating covering layer. In order to facilitate accurate control of the quality of the produced cables and ensure that the cables can be used normally in high-voltage rings such as underground, high in the air, and underwater, it is usually necessary to conduct quality inspections on the cables. Existing inspection equipment can usually only detect one quality indicator of the cable alone, thereby reducing the efficiency of cable quality inspection.

[0003] In the prior art, the invention patent with publication number CN115127921A discloses a new type of transmission cable detection equipment, including a cable body, two sets of power mechanisms and a laser rangefinder. The cable body passes through the two sets of power mechanisms, and the part of the cable body between the two sets of power mechanisms is bent. The power mechanism is used to drive the cable body to be continuously transported horizontally and drive the bent part of the cable body to swing in a circular motion. By detecting the continuously transported cable body, the purpose of comprehensive detection of the cable body at the production site can be achieved, the comprehensiveness of the detection can be effectively improved, the quality of the cable body can be accurately controlled, the detection accuracy can be improved, and the cable body itself can generate a pulling force and deform by swinging centrifugally, thereby realizing the dynamic tensile strength detection of the cable body, effectively simplifying the detection method, reducing the detection difficulty, and realizing the simultaneous detection and transportation work.

The swing plate 409 is rotatably connected to the third rotating shaft 412, and the third rotating shaft 412 is fixedly connected to one end of the support block 406. The function of the support mechanism 4 is: when the connecting plate 401 slides in the groove of the third support plate 402, the fourth gear 403 engages with the second rack plate 404 to assist in sliding, and the second motor 405 drives the first waist plate 407 to rotate, and the first waist plate 407 drives the slider 408 to slide in the sliding groove of the swing plate 409, driving the swing plate 409 to swing left and right, and the swing plate 409 rotates on the third rotating shaft 412.

[0037] like Figure 5-Figure 8 As shown, the swing mechanism 5 includes a second waist plate 501, a fifth gear 502, a sixth gear 503, a fixed shaft 504, a first swing block 505, a rack belt 506, a seventh gear 507, a first clamping rod 508, a second clamping rod 509, a first fixed column 510, a first groove block 511, a second fixed column 512, a second groove block 513, a first fixing pin 514, a second fixing pin 515, a stop block 516, an arc block 517, a connecting column 518, and a second swing block 519.

[0038] The swing mechanism 5 is as follows: the third rotating shaft 412 is rotationally connected to one end of the second waist plate 501, the third rotating shaft 412 is rotationally connected to the fifth gear 502, the fifth gear 502 is fixedly connected to the sixth gear 503, and a fixed shaft 504 is fixedly installed on the second end of the second waist plate 501, the fixed shaft 504 is rotationally connected to the first swing block 505, and the first swing block 505 is in contact with the stop column 410. When the swing plate 409 swings, the stop column 410 pushes the first swing block 505 to swing, and the first swing block 505 pushes the fifth gear 502 to rotate slightly. Then, when the swing plate 409 swings in the opposite direction, the first swing block 505 disengages from the fifth gear 502 and then contacts the first swing block 505. Another tooth surface on the fifth gear 502 contacts, driving the fifth gear 502 to rotate slightly in one direction, the sixth gear 503 is meshed with one end of the rack belt 506, the second end of the rack belt 506 is meshed with the seventh gear 507, the seventh gear 507 is rotatably connected to the cylinder 411, and the rotation of the sixth gear 503 will drive the seventh gear 507 to rotate together, and the first clamping rod 508 and the second clamping rod 509 are rotatably installed on the cylinder 411, the first clamping rod 508 and the second clamping rod 509 are fitted and connected, one end of the first clamping rod 508 is in contact with the first groove block 511, the first groove block 511 is rotatably connected to the first fixing column 510, and the first fixing column 510 is fixed. The first clamping rod 508 and the second clamping rod 509 are fixedly installed on the seventh gear 507. When the first clamping rod 508 and the second clamping rod 509 are opened, the first groove block 511 and the second groove block 513 are driven to swing, thereby clamping the first clamping rod 508 and the second clamping rod 509. One end of the second clamping rod 509 is in contact with the second groove block 513, and the second groove block 513 is rotatably connected to the second fixing column 512. The second fixing column 512 is fixedly installed on the seventh gear 507. A first fixing nail 514 is fixedly installed on the inner side of the second end of the first clamping rod 508, and a second fixing nail 515 is fixedly installed on the inner side of the second end of the second clamping rod 509. The second ends of the first clamping rod 508 and the second clamping rod 509 slide with the arc surface on the arc block 517. Contact, the arc block 517 is fixedly installed on the base 1, and both ends of the arc block 517 are in contact with the inner side of the stop block 516. The stop block 516 is fixedly installed on the base 1. When the swing mechanism 5 moves downward, the second ends of the first clamping rod 508 and the second clamping rod 509 will contact the arc surface of the arc block 517 and be stretched apart, and the stop block 516 ensures that when the swing mechanism 5 moves upward, the first clamping rod 508 and the second clamping rod 509 are closed inward, and the connecting column 518 is rotatably connected to the slider 408. The support mechanism 4 and the swing mechanism 5 are symmetrically installed, and the second swing block 519 is rotatably installed on one of the fixed shafts 504. The second swing block 519 has the same appearance as the first swing block 505, but the swing direction is opposite.

[0039] The function of the swing mechanism 5 is as follows: when the pull rod 301 is pulled and the swing mechanism 5 moves upward, the first clamping rod 508 and the second clamping rod 509 are squeezed inward and closed by the stop block 516, and the first fixing nail 514 and the second fixing nail 515 on the inner side of the second end of the first clamping rod 508 and the second clamping rod 509 are nailed into the inside of the cable to fix the cable. The first clamping rod 508 and the second clamping rod 509 are closed to drive the first groove block 511 and the second groove block 513 to swing, and the first clamping rod 508 and the second clamping rod 509 are clamped by the groove to prevent the cable from detaching. The swing plate 409 swings to drive the first swing block 505 to swing, and one end of the first swing block 505 contacts and is stuck with the tooth surface of the fifth gear 502. When the first swing block 505 swings, it first pushes the fifth gear 502 to rotate slightly in one direction, then disengages from the fifth gear 502, swings to another angle, and re-jams the other tooth surface of the fifth gear 502. The surface is pushed and continues to be pushed, so that the fifth gear 502 rotates in only one direction, and the fifth gear 502 drives the sixth gear 503 to rotate, and the sixth gear 503 drives the seventh gear 507 to rotate, so that the first clamping rod 508 and the second clamping rod 509 drive the cable to rotate, and the swing mechanism 5 is installed symmetrically. The second swing block 519 is installed on the swing mechanism 5 on the other side. The second swing block 519 has the same shape as the first swing block 505, but the swing direction is opposite, so that the two ends of the cable are twisted in opposite directions to perform a torsion test. After the test is completed, the swing mechanism 5 moves downward, and the second ends of the first clamping rod 508 and the second clamping rod 509 will contact and slide with the arc surface on the arc block 517, so that the closed first clamping rod 508 and the second clamping rod 509 are stretched open, and the first fixing nail 514 and the second fixing nail 515 are separated from the cable, and the cable is placed on the placement plate 2 for manual direct removal.

[0043] Step 3: Start the second motor 405, and the swing mechanism 5 swings left and right. The swing mechanism 5 is symmetrically installed and connected together through the connecting column 518. One of the swing mechanisms 5 swings in the opposite direction to the other swing mechanism 5, and a tensile test is performed on the cable. One of the seventh gears 507 drives the first clamping rod 508 and the second clamping rod 509 to rotate in one direction, and the other seventh gear 507 drives the first clamping rod 508 and the second clamping rod 509 to rotate in the opposite direction, and a torsion test is performed on the cable.
