KR970059465A - Grounding rod striker - Google Patents

Abstract

1) Striking device Invention Purpose To invent a striking device for easily grounding a ground rod using a current primitive manpower using a machine tool and a fork brake. 2) Machine tools, equipment and invented striking devices in areas with high rock mass and high ground resistance (difficult to secure ground resistance) during grounding works such as pole grounding (equipments, transformer, lightning arrester, grounding ground) It is used in grounding construction field to extend the service life of electric appliances and to prevent line fault in lightning by ensuring perfect grounding resistance by grounding. 3) How to use a. Use of the striking device when grounding the ground rod in soft rock and normal soil - Generator + Electric hammer drill + Striking device + Grounding rod for grounding rod - Grounding rod Use of striking device for grounding rods in light rocks and rocky soils - Forklift breta + Striking device + Grounding rods for grounding rods - Grounding rope in workshop room 4) Metal material of shredder device - Material: SM45C (KSD 3752 Carbon steel for mechanical structure) → Less wear due to impact when hit. 5) Advantages of striking device ① Prevention of worker injuries that may occur when putting the grounding rod with a hammer. → Safety work, mechanized drawing. ② It is necessary to dig a ground immediately after digging the ground without having to change the channel bucket of the fork- Improvement of workability ③ Up to 6 units in the rock area can be serially grounded so that it can be easily grounded. ④ It is easy to detect failure of power system protection device because of perfect grounding resistance. ⑤ Groundwork due to serial construction. ⑥ Decrease of grounding work to 1/10 (25 Ω resistance 150 minutes → 15 minutes ago) ⑦ Reduction of line and equipment failure due to lightning ⑧ Facilitation of permission of building related to ground excavation and civilian civil complaint prevention.

Description

Grounding rod striker

Since this is a trivial issue, I did not include the contents of the text.

FIG. 1 is a scene photograph (present and past) in which a ground rod is crushed with a hammer (hammer) without a striking device,

Figure 2 shows the striking device drawing the grounding rod on the soft rock and the ordinary soil of the grounding rod striking device - top view and bonding diagram with the grounding rod.

Claims (3)

Grounding rod Striker The material of the metal is SM45C (KSD 3752 carbon steel for mechanical structure). Striking device which is combined with electric hammer drill (28 @ for) to crush the grounding rod for the grounding. - Clause 6. The following items of the striking device for grounding the grounding rods for grounding after joining with the fork-lift brakes - In the manufacturing drawings of the striking device of Clause 6, 6-2 and 6-2-1, a. A first step of cutting a blade (blade) of a fork brake by 700 mm from a connecting portion and then a 26 mm diameter hole (hole) to a depth of 50 mm at the center, and a heat treatment step b. (2) a second step of machining the striking part striking hole (hole) by heat-treating the machining part after machining the hole (hole) of 20 mm in diameter up to the depth of 65 mm exactly in the center after the hole machining; c. A third step of processing two wings (300 in width × 200 in length × 20 in thickness) which can serve as a forklake bucket in the striking device having completed the first and second processes, and d. When the striking device is connected to the fork-lift brakes, the wing moving in the 3rd step in the direction in which the ground can be sold (Section 6-2, SECTION BB) is moved from the hole machining portion to the upper portion at an angle of 70 degrees from the center, F) After combining the striking device with the retaining stopper, connect the hole (hole) at the end of the striking device (hole machining part) at 20 mm to the striking device and the earthed stopper in the same way.
