Description

Grounding pole striker {Apparatus for ramming a grounding pole}

The present invention relates to a ground electrode striking device, and more particularly, to a ground electrode striking device to improve the work efficiency by allowing the ground electrode to be buried more quickly and easily.

In general, in order to supply electric power that has undergone several stages of transformation in a substation to consumers such as homes or buildings, overhead distribution lines supported by electric poles installed at regular intervals on the ground are used.

In order to protect the power distribution equipment from abnormal currents (brain, ground fault, surge, etc.), a ground electrode is connected to the distribution line to prevent various electrical disasters caused by a short circuit.

A buried construction of the ground electrode for this purpose will be described with reference to FIG. 1.

First, after excavating the pit of a certain depth to bury the bottom of the pole (P) on the ground (E) with equipment or manpower, and then erect the pole and dig up the excavated soil so that the pole (P) does not fall. To refill.

Next, the ground pole G is excavated using a shovel or the like in a hexahedron shape of 0.5 m long and 0.75 m deep from the pole pole P, and then grounded at a position 0.5 m away from the pole pole P. The hammer is hit on the ground (E) using a hammer, etc. and then connected to the distribution line is connected to the ground line (L) passing through the pole.

At this time, the excavation of the ground (E) to reach 0.5m horizontally in the pole (P) to hit the ground electrode (G) at a position 0.5m away from the pole (P) and a person directly using a shovel, etc. This is to secure the minimum working space required when digging the ground E to reach depth of 0.75m.

Next, if the ground resistance of the buried ground electrode G is measured using a known ground resistance measuring instrument, and if it falls below the prescribed value, the ground electrode G is additionally buried in the same manner as mentioned above. Buried at 2m or more away from (G), and connect with ground wire (L).

If the ground resistance value is less than the prescribed value even when the ground resistance value is measured again while the ground electrode G is additionally embedded as described above, the ground electrode is located at a position 2 m or more away from the ground electrode G already buried by the above-mentioned method. Further embed (G) or apply a grounding resistance reducer.

Here, the ground electrode G and the ground resistance reducing agent are further embedded or applied until the measured ground resistance value reaches a prescribed value.

Then, when the measured ground resistance reaches the specified value, the work is completed by filling the excavated pit with the excavated soil.

However, as described above, since the manpower is used for the work of embedding the ground electrode G on the ground E, labor costs and work time are increased, resulting in a decrease in work efficiency.

That is, since a person directly hits the ground electrode G using a hammer or the like on the ground E excavated using a hand-made shovel, there is a limit in embedding the ground electrode with a lot of force and a depth of 2 m or more.

Therefore, the worker is heavy and can not beat more than 2m.

In addition, when the phenomenon that the ground (E) is hardened due to the temperature during the winter, there is a problem that can not hit the ground electrode (G) with human force.

In other words, the ground (E) in the state of hitting a part of the ground electrode (G) is hard to be driven by human force anymore, there is a hassle to pull the ground electrode (G) and put again in another position.

In addition, when moving to another site in order to bury the ground electrode, such as a tool for embedding the ground electrode (G) to be placed on the vehicle by hand one by one, there is a problem not only troublesome but also mobility is reduced.

The present invention has been made to solve the above problems of the prior art, to minimize the use of manpower required to bury the ground electrode to save labor costs and to provide a ground pole striking device that maximizes the work efficiency by reducing the work time The purpose is.

Another object of the present invention is to provide a grounding pole striking device that can easily beat the grounding electrode even where the grounding electrode cannot be buried in the ground by human power.

Another object of the present invention is to provide a ground pole striking device that significantly improves the mobility to the site for embedding the ground electrode.

Referring to Figure 6, the present invention, first, when the hydraulic pressure of the hydraulic supply source 6 flows through P _I , the pressure to be used in the ram 80 is adjusted to about 30 kg / cm 2 by a relief valve 22. This adjusted pressure is filled in the actuator 70 through the check valve 23a, and the remaining pressure is stored in the accumulator 8a.

At this time, since the pressure is transmitted to the PP line when electricity is supplied to the solenoid valve 24, the pressure of the P line rapidly flows into the output chamber 73 of the actuator 70, and the piston 72 reverses. The ram 80 is raised together with the piston 72.

In this state, when the electricity supplied to the solenoid valve 24 is stopped, the pressure in the P line stops and the pressure in the output chamber 73 rapidly goes to the T line, so that some of the hydraulic pressure flows into the input chamber 74. 72 advances, and with this advanced piston 72 the ram 80 is lowered.

At this time, since the oil pressure is discharged into the input chamber 74 while the oil pressure in the output chamber 73 is discharged, the forward force of the piston 72 is further increased. Of course, this is also the impact force of the ram 80 is increased.

Then, the remaining hydraulic pressure is returned to the hydraulic supply source 6 through P _O , and the remaining hydraulic pressure above the cracking pressure of the check valve 23b is accumulated in the accumulator 8b.

Therefore, the actuator 70 and the ram 80 repeatedly perform the above process and hit the ground electrode on the ground.

At this time, the ram 80 is disposed so that the distance between the ram 80 and the ground rod embedding jig 38 is shorter than within the stroke of the ram 80, which is a distance reciprocated by the piston 72 of the actuator 70. .

Next, when the striking device 50 is operated through the electric control unit (not shown), the hydraulic pressure flows into the output chamber 73 of the actuator 70 and the ram 72 is raised by reversing the piston 72. While the hydraulic pressure in the output chamber 73 is discharged in the raised state, the hydraulic pressure flows into the input chamber 74 of the actuator 70 to advance the piston 72 so that the ram 80 is lowered.

At this time, since the hydraulic pressure is discharged and introduced from the actuator 70, the stainless steel grounding rod 36 is embedded in the ground by the ram 80 having increased impact force.

Next, as the stainless steel ground rod 36 is slowly embedded in the ground, the distance between the ram 80 and the ground rod embedding jig 38 is increased so that the ram 80 can accurately strike the ground rod embedding jig 38. None by operating the winch 15 to proceed with the work while adjusting the distance between the two.
