Anti-falling device for high-altitude overhaul of single-phase column head type switch blade

Abstract

The invention relates to the field of power supply, in particular to an anti-falling device for high-altitude overhaul of a single-phase column head type switch blade. The anti-falling device for high-altitude overhaul of the single-phase column head type switch blade is convenient to disassemble and assemble, better in safety and higher in overhaul efficiency. A platform, a porcelain column insulator and a switch blade are sequentially arranged on the top of a support column. The anti-falling device comprises a supporting cylinder and an anti-falling rod. The anti-falling rod is detachably connected in the supporting cylinder. The supporting cylinder is connected to the support column through a fixing connecting structure. A hanging ring used for being connected with a safety belt bucklering is arranged at the top of the anti-falling rod. The anti-falling device is convenient to disassemble and assemble, capable of protecting high-altitude overhaul operators, and better in overhaul efficiency.

Description

technical field [0001] The invention relates to the field of power supply, in particular to an anti-falling device for high-altitude maintenance of a single-phase column head switch knife. Background technique [0002] Knife maintenance is a high-altitude maintenance operation. In order to ensure the safety of the maintenance personnel during the maintenance of the knife, safety belts must be used. However, the porcelain bottle of the knife support is not a solid component. The seat belt is attached to a non-solid structure, and other companies have had accidents in which the seat belt was directly hung on the pillar porcelain bottle and the pillar porcelain bottle was broken, so other devices must be borrowed for the maintenance of the switch knife. For the rotary arm type switch knife with channel steel structure, the corresponding channel steel anti-fall bar can be used, but the switch knife with single-phase column head structure currently lacks corresponding auxiliary d...

[0002] Knife maintenance is a high-altitude maintenance operation. In order to ensure the safety of the maintenance personnel during the maintenance of the knife, safety belts must be used. However, the porcelain bottle of the knife support is not a solid component. The seat belt is attached to a non-solid structure, and other companies have had accidents in which the seat belt was directly hung on the pillar porcelain bottle and the pillar porcelain bottle was broken, so the maintenance of the switch knife must use other devices

For the rotary arm type switch knife with channel steel structure, the corresponding channel steel anti-fall bar can be used, but the switch knife with single-phase column head structure currently lacks corresponding auxiliary devices, and when it exceeds 2 meters, it can only be used to build scaffolding Or use the method of high-altitude bucket truck

Building scaffolding is time-consuming and labor-intensive. It often takes longer to build scaffolding than to repair the switch blades, and renting high-altitude bucket trucks requires additional capital costs (the market price is 800 yuan / time), and bucket truck drivers may not have enough electricity. Knowledge, and it is difficult to enter and exit with the maintenance personnel, which is likely to become a major safety hazard
