Portable grounding down lead reset mounting apparatus and method

Abstract

Disclosed is a portable grounding down lead reset mounting apparatus used for being matched with a lifting mechanism to reset and mount the grounding down lead to a tower angle iron. The portable grounding down lead reset mounting apparatus comprises a locking mechanism for tightly holding the tower angle iron detachably, wherein the locking mechanism comprises a main beam used for fixing the lifting mechanism, a first tightening assembly which is arranged at one end of the main beam and can buckle one side edge of the tower angle iron, and a second tightening assembly which is arranged at the other end of the main beam and can buckle the other side edge of the tower angle iron; the second tightening assembly comprises a tightening seat which can be hinged at the other end of the main beam in a swinging manner in a locking position and a releasing position, a pull rod which can be hinged on the tightening seat in a swinging manner, and a second buckling part which is arranged on the pull rod and can buckle the other side edge of the tower angle iron; and it is set that when the tightening seat swings from the releasing position to the locking position, the pull rod can be driven to retract backwardly so as to enable the second buckling part to tightly buckle the edge of the tower angle iron.

Description

technical field [0001] The invention relates to a portable grounding down conductor reset installation device and method. Background technique [0002] According to the operation and maintenance requirements of the transmission line, the grounding resistance measurement of the transmission line is carried out every year. If a lightning trip occurs on the line, it is also necessary to measure the grounding resistance of the faulty line section. During the measurement process, in the previous construction, Since the landfill soil is mostly loose soil, after a long period of accumulation, the landfill soil will compact the grounding grid layer by layer, and the original enough grounding down conductors will be under the pressure of the upper soil, and will continue to be forced downward, resulting in a shorter active length. , When the fastening nut is untied, it shrinks down instantly, which affects the recovery work. In severe cases, it is difficult to reset the grounding dow...

[0002] According to the operation and maintenance requirements of the transmission line, the grounding resistance measurement of the transmission line is carried out every year. If a lightning trip occurs on the line, it is also necessary to measure the grounding resistance of the faulty line section. During the measurement process, in the previous construction, Since the landfill soil is mostly loose soil, after a long period of accumulation, the landfill soil will compact the grounding grid layer by layer, and the original enough grounding down conductors will be under the pressure of the upper soil, and will continue to be forced downward, resulting in a shorter active length. , When the fastening nut is unfastened, it shrinks down instantly, which affects the recovery work. In serious cases, it is difficult to reset the grounding down conductor by hand or other tools.

This method requires the staff to spend a lot of energy and time, resulting in sore arms, red and swollen palms, and the hands are easily scratched by the grounding conductor while exerting force, causing safety hazards
