Description

Technical Field

[0001] The invention relates to the technical field of live working tools and apparatus, and in particular to a safety fixing device for overhead line leads. Background Art

[0002] In the practice of live working in distribution networks, live disconnection and connection of lead wires is a routine task, but in the past, the removed lead wires were often left hanging in the air. This practice poses potential safety risks that cannot be ignored. First, it is very easy to cause phase-to-phase short circuit problems. Especially under the action of wind, the lead wires in the air are prone to contact with the lead wires of adjacent phases, directly leading to short circuit accidents. Secondly, the lead wires that have been connected to the line may also generate induced electricity to the unconnected phases, which will not only interfere with the subsequent work of the operators, but also pose a safety hazard of touching the wires. Furthermore, for operators who use insulating gloves to disconnect and connect live lead wires, they need to always pay attention to avoid the lead wires hanging in the air, which increases the difficulty and complexity of the operation.

[0003] In the existing method, the operator uses an insulating lock rod to lock the drainage wire near one end of the line, and the ground electrician uses an insulating rope to pass the insulating wire cutter and three-tooth pick to the pole, and fixes the lowered drainage wire on the crossarm or pole to prevent it from swinging or affecting the operation. The operation of winding the drainage wire at high altitude remains unchanged and has a greater safety hazard. It is not suitable to wind the drainage wire on the pole if it is too long or too short. Summary of the invention

[0031] The working principle of this embodiment:

[0032] Each set of lead wire safety fixing device consists of a first insulating rod and a second insulating rod. Both ends of the first insulating rod have clamping structures, one of which can rotate 360° with the insulating rod as the center (loosen the screw on the sleeve during rotation, and rotate the sleeve so that the clamping structure is in the required position). A sleeve is installed at one end of the second insulating rod, and a clamping structure is installed at the other end. When in use, the clamping structure on the second insulating rod is installed on the main line so that the first insulating rod is installed vertically below the line conductor. At the same time, the position of the second insulating rod on the first insulating rod and the clamping structure on the second insulating rod are adjusted so that the clamping structure can clamp the lead wire in a suitable orientation. A device specifically used for the safe fixing of overhead line leads is provided, which can flexibly adjust the clamping position to adapt to different line layouts. It can effectively fix the lead wire, reduce safety hazards, and is relatively convenient to operate, reducing labor intensity.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the wire clamping assembly includes a wire clamping block, a pressing tongue, a connecting rod and a sleeve; a pressing tongue is provided at the left end of the wire clamping block, and a connecting rod is provided on the bottom surface; sleeves are provided at one end of the first insulating rod for mounting the wire clamping assembly and at both ends of the second insulating rod; one end of the connecting rod is connected to the bottom surface of the wire clamping block, and the other end is connected to the sleeve.

[0035] By loosening the fixing screw, the pressing tongue is pressed toward the inside of the wire clamping block, and the pressing tongue is loosened after the lead is placed, and the screw is tightened to clamp the lead. A sleeve and a connecting rod are provided on the first insulating rod and the second insulating rod to connect the wire clamping assembly. Loosen the fixing screw 2, press the pressing tongue 11 toward the inside of the wire clamping block 12, place the lead in the wire holding hole formed by the pressing tongue 11 and the wire clamping block 12, loosen the pressing tongue 11, and the pressing tongue 11 rebounds to its original position, and tighten the screw 2 to achieve the purpose of clamping the lead.

[0036] The working principle of this embodiment is the same as that of Embodiment 1.

[0037] Example 3

[0038] This embodiment is different from the second embodiment in that it further comprises a fixing screw; a threaded hole is formed at the lower end of the wire pressing block, and a through hole is formed at the lower end of the pressing tongue; the fixing screw passes through the through hole at the lower end of the pressing tongue and the threaded hole at the lower end of the wire pressing block to fix the pressing tongue to the wire pressing block. By adding a fixing screw to fix the pressing tongue to the wire pressing block, the stability of the pressing tongue when clamping the lead is ensured, the firmness of the wire clamping structure is further enhanced, the lead is prevented from slipping off, and the safety of the device is improved.

[0039] The working principle of this embodiment is the same as that of Embodiment 1.

[0040] Example 4

[0041] This embodiment differs from the third embodiment in that it further comprises a connecting screw; a through hole is formed in the middle of the connecting rod and the sleeve; the connecting screw passes through the through hole in the middle of the connecting rod and the sleeve to connect the connecting rod and the sleeve together. The connecting rod and the sleeve are connected together by the connecting screw, so that the clamping assembly is more firmly connected to the insulating rod, ensuring that the clamping assembly will not be separated from the insulating rod during use, thereby improving the overall reliability of the device.

[0042] The working principle of this embodiment is the same as that of Embodiment 1.

[0043] Example 5

[0044] This embodiment differs from Embodiment 4 in that it further includes a sliding sleeve; the sliding sleeve is installed at the other end of the first insulating rod; the sliding sleeve is sleeved on the rod body of the second insulating rod. The sliding sleeve is installed on the first insulating rod, and the sliding sleeve is sleeved on the rod body of the second insulating rod, and the position can be adjusted, which increases the flexibility of the device. The position of the second insulating rod can be adjusted according to actual needs to better adapt to different working scenarios.

[0045] The working principle of this embodiment is the same as that of Embodiment 1.

[0046] Example 6

[0047] The difference between this embodiment and embodiment 5 is that a fixing threaded hole is provided in the middle of the sliding sleeve. The fixing threaded hole is provided in the middle of the sliding sleeve, and the sliding sleeve can be fixed to a specific position on the second insulating rod by a fixing member, ensuring that the device will not move due to external force after the position is adjusted, thereby improving the stability of the fixed lead.

[0048] The working principle of this embodiment is the same as that of Embodiment 1.

[0049] Example 7

[0050] The difference between this embodiment and embodiment 6 is that the upper ends of the pressing tongue and the wire pressing block are respectively provided with arc-shaped grooves. The arc-shaped grooves are respectively provided at the upper ends of the pressing tongue and the wire pressing block to better fit the shape of the lead and clamp the lead. The arc-shaped grooves increase the contact area with the lead, reduce damage to the lead, and improve the firmness of the clamping.
