Embodiment 1

[0022] Such as figure 1 As shown, a power grounding device includes a base 19 provided with a walking mechanism, a transmission shaft 1, a ratchet wheel 6, a supporting frame body 2 provided on the base, and a pawl 8 installed on the supporting frame body. The pawl 8 can Mounted on the support frame body 2 through the rotating shaft 10, the transmission shaft is connected to the support frame body 2 through the seat sleeve 3, the ratchet is movably connected to the transmission shaft, and the transmission shaft 1 is installed and connected to the bearing housing through the thrust bearing 11, The transmission shaft 1 is provided with a limiting structure 1-1 and a friction component, which play a limiting role when the transmission shaft moves to the right, wherein the limiting structure 1-1 is provided on the load side of the seat cover 3, so The transmission shaft is provided with a limiting structure and a friction component, one end of the transmission shaft is provided wit...

Embodiment 2

[0034] The grounding post is provided with a steel brazing guide sleeve 17 to prevent it from being skewed, and more importantly, it can prevent the counterweight from landing and hurting others. The surrounding side of the grounding column is provided with a movable cover plate 18 to prevent the counterweight from landing and hurting others.

Embodiment 3

[0036] The longitudinal section of the steel drill is triangular, which is convenient for ejecting the stopper.

Abstract

The invention discloses an electric grounding device. The electric grounding device comprises a base provided with a walking mechanism, a transmission shaft, a ratchet wheel, a supporting frame arranged on the base and a pawl installed on the supporting frame; the transmission shaft is connected with the supporting frame through a base sleeve, the ratchet wheel is movably connected with the transmission shaft, a limiting structure and a friction assembly are arranged on the transmission shaft, a rope winding roller is arranged at one end of the transmission shaft, a fixed pulley for a rope to penetrating through is arranged on a cross arm of the supporting frame, a balancing weight is arranged at the free end of the rope on the rope winding roller, and a grounding column guide sleeve movably connected with the base is arranged at one side of the base. By means of the device, the grounding column can be accurately installed, installing time is short, installing efficiency is high, and the device is convenient to operate, safe and reliable.

Description

Technical field [0001] The invention relates to the technical field of power equipment grounding, in particular to a power grounding device. Background technique [0002] Power transmission lines and related equipment are mostly outdoors and are prone to lightning strikes. Line tripping due to lightning strikes often occurs. In order to prevent lightning strikes, it is necessary to install a grounding device on the transmission line to guide the current generated by the lightning strike to the earth to prevent the wire or the transmission equipment from being damaged by the lightning voltage. The grounding device needs to be reliably grounded, and metal grounding stakes are usually used. The grounding pile is driven into the ground by external hammering, but due to the capacity of the grounding pile being pulled out, the grounding pile is often stolen, unsafe factors caused by the operation of the line and the line, and the stolen grounding pile needs to be repaired by maintenan...
