Description

Technical Field

[0001] This utility model relates to a grounding grid for equipment, and more particularly to a special mechanism for nailing round steel grounding electrodes onto the grounding grid for equipment during civil construction. Background Technology

[0002] Various electrical equipment is installed in power transmission and transformation generator rooms, all of which are equipped with grounding grids. The main function of the grounding grid is to reliably ground the equipment in the generator room, prevent the equipment from being struck by lightning, and ensure the safe operation of the equipment. Round steel grounding electrodes are installed on the grounding grid. These electrodes need to be vertically driven into the ground to the designed depth so that the grounding grid can function properly. The length of the round steel grounding electrodes is generally 2.5-5 meters. During on-site installation, due to their length, the round steel grounding electrodes are prone to bending during the driving process, requiring repeated correction of their posture. Using a drilling machine for pre-drilling has the disadvantage of high construction costs. How to implement manual driving more economically and overcome the defect of the round steel grounding electrodes being prone to bending during driving has become a problem that needs to be solved in on-site construction. Summary of the Invention

[0003] This utility model provides a special mechanism for nailing round steel grounding electrodes on a grounding grid, which solves the technical problem of how to implement manual nailing in a more economical way and overcomes the problem of round steel grounding electrodes being easily bent during nailing.

[0004] This utility model solves the above technical problems through the following technical solution:

[0005] A specialized mechanism for installing round steel grounding electrodes on a grounding grid includes a soil reference surface. A round steel grounding electrode is vertically inserted into the soil reference surface, with its lower end embedded in the soil reference surface. A first steel pipe is movably sleeved onto the upper end of the round steel grounding electrode. A first rectangular counterweight block is welded to the top end of the first steel pipe. The top end of the first steel pipe is fixedly connected to the center of the bottom surface of the first rectangular counterweight block via a circumferential weld. A second steel pipe is connected to the lower end of the first steel pipe. The lower end of one section of steel pipe is connected to the upper end of the second section of steel pipe by the first thread; the lower end of the second section of steel pipe is connected to the third section of steel pipe by the second thread; the lower end of the third section of steel pipe is connected to the fourth section of steel pipe by the third thread; the upper end of the round steel grounding electrode passes through the fourth section of steel pipe, the third section of steel pipe, and the second section of steel pipe in sequence from bottom to top, and is then movably installed in the first section of steel pipe.

[0006] A conical groove is provided on the top surface of the first rectangular counterweight block, and a second rectangular counterweight block is provided on the top surface of the first rectangular counterweight block. A conical protrusion is provided on the bottom surface of the second rectangular counterweight block, and the conical protrusion is inserted into the conical groove.

[0007] This invention utilizes multi-segment connected steel pipes as movable guide sleeves to guide and constrain the round steel grounding electrode during its downward driving, overcoming the defect that the round steel grounding electrode is prone to bending during the driving process. The round steel grounding electrode is first inserted into the sleeve of the special tool of this invention. The special tool is then manually raised and lowered vertically, and the counterweight at the top is used to hammer the top of the round steel grounding electrode, causing it to penetrate into the soil. After the round steel grounding electrode is driven to a certain depth, the steel pipes connected to the lower end are disassembled in sequence, so that the bottom end of the steel pipe always maintains a certain distance from the soil, ensuring that the special hammer tool has space to be raised and lowered vertically until the round steel grounding electrode is completely driven into the soil.
