Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive testing and quality testing of hardware crimping of power transmission line, in particular to an auxiliary tool suitable for wire hanging testing of digital ray flat panel detectors. Background Art

[0002] In recent years, there have been many line operation accidents such as line tripping, power outages, and tower collapses caused by quality problems in the crimping of tension clamps. According to post-processing analysis, most accidents are caused by crimping quality problems such as the conductor and ground wire not being properly inserted into the crimping tube or the crimping position not complying with relevant regulations. When the line is under heavy load operation, tension clamps that do not meet the crimping requirements can easily cause local heating and excessive temperatures to damage the conductors, resulting in reduced connection strength, or cause disconnection due to insufficient crimping grip, especially when the conductors are covered with ice or dancing, which is very likely to cause disconnection accidents due to crimping quality problems. Therefore, it is necessary to accurately and efficiently detect the crimping quality of tension clamps and deal with the corresponding defects in a timely manner.

[0003] In view of the importance of quality inspection and evaluation of transmission line tension clamp crimping, technicians in this field have proposed a variety of inspection methods. At present, the most commonly used is the drone digital radiographic nondestructive testing technology, which is gradually widely used because it can avoid manual tower inspection, reduce the safety risks of manual operations, obtain digital radiographic images in real time on site, and judge the internal crimping quality of hardware clamps in real time. It can also perform live detection and has high detection efficiency. However, the following technical problems were found in the study: In the process of drone digital radiographic nondestructive testing, there is a lack of effective auxiliary tooling to protect the safety of the digital radiographic flat-panel detector and the wire itself, and to assist in improving the hanging efficiency. Inappropriate auxiliary tooling may damage the transmission line conductor and affect the reliability of the detection equipment hanging line, and ultimately affect the effect of drone digital radiographic nondestructive testing.

[0029] Embodiment 1

[0030] like Figure 1 As shown, the utility model provides an auxiliary tooling suitable for hanging line detection of digital X-ray flat-panel detectors, comprising: a counterweight hook 1, a flat-panel detector protection frame 2, a flat-panel detector front protection plate 8, a flat-panel detector rear protection plate 9 and a plurality of insulating guide legs 3, wherein the flat-panel detector front protection plate 8 and the flat-panel detector rear protection plate 9 are used to cover the flat-panel detector protection frame 2.

[0031] The flat panel detector protection frame 2 is made of an aluminum alloy profile that matches the length, width and thickness of the digital ray flat panel detector. The flat panel detector protection frame 2 is in a rectangular shape and its size matches that of the flat panel detector, which is convenient for embedding the digital ray flat panel detector. Figure 3 As shown, according to the actual button positions on the digital ray flat panel detector, a digital ray flat panel detector button hole 4 is reserved on the upper frame of the flat panel detector protection frame. In this embodiment, the digital ray flat panel detector can be selected from existing technologies.

[0032] like Figure 1 As shown, the two side frames of the flat panel detector protection frame 2 are fixedly mounted with counterweight hooks 1 by detachable screws. Figure 2 As shown, the inner side of the counterweight hook 1 adopts a structure in which a semicircular arc is introduced by an inclined straight surface. The semicircular arc matches the hanging wire to be detected, and the overall shape of the counterweight hook 1 is a curved hook protruding outward from the front protective plate of the flat-panel detector. In this embodiment, the thickness of the counterweight hook 1 is 20mm to 50mm, and its material is a forged aluminum plate. The inner semicircular arc and the edge of the protruding side of the curved hook are cut in a straight line. The inner side of the counterweight hook 1 adopts a structure in which a semicircular arc is introduced by an inclined straight surface, which helps the hook to slide smoothly into the conductor hardware during the process of hoisting and hanging wires. The weight of the counterweight hook itself reduces the slipping and circling of the flat-panel detector during the hanging process, and increases the stability and convenience of the detection equipment hanging wires. The wide hook structure of the counterweight hook reduces the hidden danger that the tooling may scratch the transmission line conductors.

[0033] like Figure 1As shown, a plurality of insulating guide legs 3 are fixedly mounted on the lower frame of the flat-panel detector protection frame 2. Specifically, a plurality of insulating guide legs 3 are fixed on the lower frame of the flat-panel detector protection frame by detachable screws and extend downward. The insulating guide legs are made of insulating resin material that matches the thickness of the flat-panel detector protection frame. In this embodiment, the length of the insulating guide legs 3 extending downward is 300 to 500 mm, and the width of the insulating guide legs 3 themselves is 30 to 70 mm. The insulating guide legs 3 play a role in guiding the digital ray flat-panel detector to slide into the position of the wire fittings in advance, avoiding direct collision with the wire during the hanging process of the digital ray flat-panel detector. The insulating guide legs 3 themselves adopt an insulating design to avoid close connection with other lines during the live hanging process, thereby realizing safe distance control of the equipment.

[0034] In this embodiment, the flat panel detector front protection plate 8 and the flat panel detector rear protection plate 9 are made of aluminum alloy thin plates that match the flat panel detector protection frame 2, and are covered and installed on the flat panel detector protection frame 2 by detachable screws. Figure 1 As shown, an imaging area matching the imaging area of ​​the flat-panel detector is reserved on the front protection plate 8 of the flat-panel detector, thereby ensuring an effective radiation imaging area; a wireless transmitter reserved exposed area 6 and a battery removal reserved exposed area 7 matching the wireless transmitter and the battery on the flat-panel detector are reserved on the rear protection plate 9 of the flat-panel detector, respectively, thereby ensuring that the external signal of the wireless transmitter is not shielded by the aluminum alloy sheet, and that the protection plate does not need to be removed for battery replacement, thereby improving detection efficiency; the planar structure formed by other non-imaging areas and non-exposed areas ensures the strength of the front and rear protection of the flat-panel detector, while achieving the equipotential conductivity requirement when the flat-panel detector is used for live detection.

[0035] In this embodiment, the auxiliary tooling also includes a lifting hole 5, which is a forged aluminum plate that matches the thickness of the flat-panel detector protection frame, and the lifting hole 5 is in the shape of a lifting ear. Two lifting holes 5 are provided, and the two lifting holes are respectively fixed to the two ends of the upper frame of the flat-panel detector protection frame by detachable screws.
