Description

Technical Field

[0001] The invention relates to the technical field of live working on power transmission lines, and in particular to a special tool for processing ground potential defects of a jumper tube bowl head on a power transmission line. Background Art

[0002] In the transmission lines from 35kV to 2200kV, the connection between the jumper tube and the bowl head of the tension tower is an important link to ensure the safe and stable operation of the power system. However, due to long-term operation and various influencing factors, this part may have some defects, bringing serious safety hazards. The following is a detailed analysis and description of several major defects:

[0003] 1. The connecting bolts and nuts between the jumper tube and the bowl head are missing or loose:

[0004] During long-term power operation, the connecting bolts and nuts between the jumper tube and the bowl head may loosen or fall off due to vibration, temperature changes or other mechanical factors. If this situation is not handled in time, it will cause the connection between the jumper tube and the bowl head to be unstable, and may even cause the jumper to detach, resulting in the risk of the jumper being directly grounded. Once this risk occurs, it will not only have a serious impact on the power system, but may also cause equipment damage or safety accidents.

[0005] 2. The connecting bolt between the jumper tube and the bowl head is missing the cotter pin:

[0006] The screw of the jumper tube connecting the cup head is usually equipped with a split pin to prevent the nut from loosening or falling off. However, during long-term operation, the split pin may be lost due to material fatigue or improper operation. In this case, the stability of the nut cannot be guaranteed, which may cause it to loosen, further leading to the problem of loose connection, and ultimately increasing the risk of jumper grounding. Therefore, regular inspection and replacement of missing split pins is an important measure to ensure safety.

[0007] 3. The jumper tube and the bowl head connection do not match:

[0008] During the construction process, if an inappropriate connection component is selected, the jumper tube and the bowl head connection may not match. For example, the design requires the use of a double bowl head, but a single bowl head is mistakenly used during construction, which will cause uneven force on the jumper tube. Long-term operation and external forces may cause the nut to loosen or be missing, thereby increasing the risk of accidental grounding of the jumper.

[0009] At present, the treatment of the above defects mainly relies on power outages, which brings great challenges and inconveniences in actual operations. Although live working is technically feasible, the risks and complexity involved are greatly increased. Therefore, it is urgent to develop tools for handling ground potential defects in jumper bowls of transmission lines to carry out effective maintenance and repair work under live conditions to ensure the safe and stable operation of the power system.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0051] In order to eliminate the defect of the jumper bowl of the transmission line, this embodiment provides a special tool for processing the ground potential of the jumper bowl of the transmission line; Figure 1 As shown, the special tools for processing the defective ground potential of the jumper tube bowl head of the transmission line include a suspension wire clamp holding tool 1, a jumper tube bowl head assembly and disassembly tool 2, a cotter pin assembly and disassembly tool 3, and an M-pin assembly and disassembly tool 4. The above tools are all connected to an insulating operating rod 5 through a universal joint.

[0052] The following is a detailed description of the structure and function of the above tools:

[0053] like Figure 2 As shown, the function of the suspension wire clamp holding tool 1 is that an operator at ground potential can clamp and fix the connecting piece 6 of the suspension wire clamp through the suspension wire clamp holding tool 1 .

[0054] like Figure 2 As shown, the suspension wire clamp holding tool 1 is F-shaped as a whole, and includes a universal joint female head 13, a first fixing plate 14, a second fixing plate 15, a fixed clamping rod 16, a movable clamping rod 17 and a clamping spring 18.

The second fixing plate 15 is connected to the first fixing plate 14, and the second fixing plate 15 is arranged parallel to the first fixing plate 14, and a space gap is formed between the first fixing plate 14 and the first fixing plate 14. The clamping spring 18 is installed in the space gap to control the movable clamping rod 17; the length of the movable clamping rod 17 is greater than that of the fixed clamping rod 16, and the movable clamping rod 17 is located between the first fixed plate 14 and the second fixed plate 15 and is slidably connected to the first fixed plate 14; preferably, in this embodiment, a long waist-shaped hole 19 is provided on the first fixed plate 14, and one end of the movable clamping rod 17 is inserted into the space gap through the long waist-shaped hole 19 to achieve a slidable connection with the first fixed plate 14. In addition, since the connecting piece 6 of the suspension clamp is a metal sheet, considering the problem of holding stability, teeth are provided on the opposite sides of the movable clamping rod 17 and the fixed clamping rod 16 in this embodiment.

[0055] When using, Figure 2 and Figure 3 As shown, the end of the movable clamping rod 17 away from the first fixed plate 14 first touches the connecting piece 6 of the suspension wire clamp; then it is pushed horizontally, and the movable clamping rod 17 moves toward the side of the universal joint female head 13, and the clamping spring 18 is compressed at the same time; when the spacing between the movable clamping rod 17 and the fixed clamping rod 16 is sufficient for the connecting piece to enter, the connecting piece 6 of the suspension wire clamp enters between the movable clamping rod 17 and the fixed clamping rod 16, and is clamped by the fixed clamping rod 16 and the movable clamping rod 17, thereby ensuring that the position of the connecting piece 6 of the suspension wire clamp is fixed.

[0056] like Figure 3 and Figure 4 As shown, the function of the jumper tube bowl head assembly and disassembly tool 2 is that the operator is at ground potential and can use the jumper tube bowl head assembly and disassembly tool 2 to assemble and disassemble the connecting bolts 8 between the connecting piece 6 of the suspension wire clamp and the jumper tube bowl head 7, thereby replacing the jumper tube bowl head 7 and tightening the connecting bolts 8 between the connecting piece 6 of the suspension wire clamp and the jumper tube bowl head 7.

A battery 30 connected to the driving motor 27 by wire is also mounted on the C-shaped mounting plate 23.

[0060] It should be noted that the electric wrench 22 and the drive motor 27 in this embodiment are equipped with a remote controller 31 for remote control; in addition, the guide rod 24 and the lead screw 28 are vertically coaxial.

[0061] If it is necessary to tighten the connecting bolt 8 between the clip connecting piece 6 of the suspension line and the jumper tube bowl head 7, as shown in 3, the operator is at ground potential and operates through the nut disassembly component 21 of the jumper tube bowl head assembly and disassembly tool 2; first, the first magnetic sleeve 25 is put on the nut of the bolt, and then the driving motor 27 is controlled to lower the height of the screw rod 28, so that the third magnetic sleeve 29 is put on the nut; finally, the operator is at ground potential and operates through the bolt disassembly component 20 of the jumper tube bowl head assembly and disassembly tool 2, so that the hexagonal plug at the output end of the electric wrench 22 is inserted into the second magnetic sleeve 26, and the electric wrench 22 is started to drive the second magnetic sleeve 26, the guide rod 24 and the first magnetic sleeve 25 to rotate synchronously, and the connecting bolt 8 is tightened.

[0062] If the jumper tube bowl 7 needs to be replaced, the electric wrench 22 of the bolt disassembly assembly 20 and the drive motor 27 of the nut disassembly assembly 21 need to be operated at the same time. Figure 4 As shown, after the bolt and the nut are separated, the nut is adsorbed in the third magnetic sleeve 29, and the jumper tube bowl head 7 can be disassembled relative to the suspension clamp.

[0063] like Figure 5 and Figure 6As shown, the function of the cotter pin assembly and disassembly tool 3 is that the operator is at ground potential and can install and disassemble the cotter pin 9 on the connecting bolt 8 through the cotter pin assembly and disassembly tool 3; the function of the M-pin assembly and disassembly tool 4 is that the operator is at ground potential and can install and disassemble the M-pin 10 in the jumper tube bowl head 7 through the M-pin assembly and disassembly tool 4.
