Embodiment 1

[0023] Such as figure 1 , 2 As shown, a power grounding column for electric power engineering includes a base 19 provided with a traveling mechanism, a transmission shaft 1, a ratchet 6, a support frame body 2 arranged on the base and a pawl 8 installed on the support frame body, The ratchet 8 can be installed on the support frame body 2 through the rotating shaft 10, the transmission shaft is connected with the support frame body 2 through the seat cover 3, the ratchet is movably connected with the transmission shaft, and the transmission shaft 1 is connected with the bearing seat through the thrust bearing 11 Wear-through connection, the drive shaft 1 is provided with a limit structure 1-1 and a friction assembly, which play a limit role when the drive shaft moves to the right, wherein the limit structure 1-1 is set on the seat cover 3 On the load side, the transmission shaft is provided with a limit structure and a friction assembly, one end of the transmission shaft is pr...

Embodiment 2

[0035] The grounding column is provided with a steel drill guide sleeve 17 to prevent the deviation from being smashed, and more importantly, it can prevent the counterweight from falling to the ground and hurting others. Movable cover plate 18 is provided on the grounding post circumference side, prevents counterweight from falling to the ground, and hurts other people.

Embodiment 3

[0037] The longitudinal section of the steel drill is triangular, which is convenient for pushing out the stopper.

Abstract

The invention discloses an electric power grounding column used for electric power engineering. The electric power grounding column comprises a base equipped with a walking mechanism, a transmission shaft, a ratchet wheel, a supporting frame body arranged on the base, and a pallet arranged on the supporting frame body, wherein the transmission shaft is connected with the supporting frame body through a seat sleeve; the ratchet wheel is movably connected with the transmission shaft; the transmission shaft is provided with a limiting structure and a friction assembly; a rope winding roller is arranged at one end of the transmission shaft; a fixed pulley for allowing a rope to pass through is arranged on a transverse arm of the supporting frame body; a weighing block is arranged at the rope free end on the rope winding roller; and a grounding column guiding sleeve movably connected with the base is arranged on one side of the base. By adoption of the electric power grounding column, accurate installation of the grounding column can be realized rapidly; the installation time is short and the installation efficiency is high; and in addition, the electric power grounding column is convenient to operate, and safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electric equipment grounding, in particular to an electric grounding column for electric power engineering. Background technique [0002] Power transmission lines and related equipment are mostly located outdoors and are prone to lightning strikes, and line trips due to lightning strikes often occur. In order to prevent lightning strikes, it is necessary to install a grounding device for the transmission line to guide the current generated by the lightning strike to the earth, so as to prevent the wires or transmission equipment from being damaged by the lightning voltage. The grounding device requires reliable grounding, and usually uses metal grounding piles. Grounding stakes are hammered into the ground by external force, but because the capacity of grounding stakes is pulled out, grounding stakes are often stolen, and the operation of the line brings unsafe factors, and the stolen grounding stakes ne...
