Description

Technical Field

[0001] This utility model relates to a semi-automatic grounding rod, belonging to the field of power tool technology. Background Technology

[0002] Grounding wires are a safety barrier for maintenance personnel and a lifeline for power workers, preventing injury from sudden power surges. Installing grounding pins is a crucial part of the grounding process. However, with rapid urban development and a surge in paved road coverage, many existing dirt roads in urban areas are now covered with concrete or asphalt, and some sections are frozen in winter. Therefore, when encountering power poles without grounding down conductors during power outages, manual installation of grounding pins is necessary.

[0003] In existing technologies, grounding rods are typically driven into the soil manually with a hammer or using a simple pile driver. While manual methods are low-cost, they are time-consuming, labor-intensive, and difficult to maintain verticality, which can easily increase grounding resistance. Commercially available pile drivers are mostly large, bulky equipment with poor guidance, making them unsuitable for operation in confined or irregular spaces. Furthermore, their impact and drilling functions are separate, requiring multiple machines to work together, resulting in a cumbersome construction process and complex equipment scheduling.

[0004] Therefore, it is necessary to design a semi-automatic grounding rod that can solve the problems of unstable grounding rod support, unstable guidance, and low efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a semi-automatic grounding rod, which solves the problems of unstable grounding rod support, unstable guidance, and low efficiency.

[0020] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0021] like Figures 1-3 As shown, a semi-automatic grounding rod includes a support column 1, an electric hammer 2, a grounding rod 3, and a drill bit 4. The electric hammer 2 can be fixed on the support column 1, the electric hammer 2 is provided at the top of the grounding rod 3, and the drill bit 4 is provided at the bottom of the grounding rod 3.

[0022] The support column 1 provides overall support and guidance for the device. The electric hammer 2 is connected to the support column 1 through the guide sleeve 23 to ensure that the electric hammer moves stably along the vertical direction of the support column 1. The electric hammer 2 can provide impact and torque to the grounding rod 3. The grounding rod 3 can withstand the impact of the electric hammer and transmit it to the drill bit. The drill bit 4 can drill through the layer to ensure the overall grounding effect of the grounding rod 3.

[0023] Reference Figure 1 The support column 1 is a longitudinally arranged cylindrical column made of steel pipe or aluminum alloy. The support column 1 can serve as a guide shaft for the electric hammer 2 and the grounding rod 3, ensuring that the impact and rotational force of the electric hammer 2 can act in the predetermined direction without deviation.

[0024] At least three support columns 11 are provided at the bottom of the support column 1, extending outwards and located on the same horizontal plane. In this embodiment, three support columns 11 are provided at the bottom of the support column 1, with a spacing of 120° between them. The support columns 11 are straight rods with a cylindrical cross-section. When the support column 1 is placed on the ground, the support columns 11 can form a stable three-legged support structure, capable of withstanding the power of the electric hammer 2 and preventing the device from tipping over. The support columns 11 are connected and fixed to the support column 1 by welding, ensuring that the angle between adjacent support columns 11 is consistent.

[0025] The electric hammer 2 has an output end with a groove, and a bolt is installed on the side of the groove. The output end can be connected to the grounding rod 3 via the bolt. A guide sleeve 23 is provided on the side of the electric hammer 2, which can be fixed to the outside of the support column 1. A handle 22 is provided at the end of the electric hammer 2 away from the support column 1, and the electric hammer 2 can be controlled by controlling the handle 22. The electric hammer 2 can provide sufficient impact force and torque to press the grounding rod 3 into the ground and can drive the drill bit 4 to rotate.

[0026] The electric hammer 2 can rotate forward or backward, and can be used to install and remove the grounding rod 3.

[0027] A battery 21 is installed on the upper part of the electric hammer 2. In this embodiment, the battery 21 is fixed to the electric hammer 2 by a clip. The battery 21 can provide power to the electric hammer 2, ensuring that the device can work even without an external power source. By replacing the battery 21, the electric hammer 2 can work continuously.

[0028] The handle 22 is located on the side of the electric hammer 2 away from the support column 1, and is in a ring shape perpendicular to the support column 1. This makes it easy for the operator to hold and increases stability, and also makes it easier for the operator to adjust the motor 2.

[0029] The electric hammer 2 is connected to the support column 1 through a guide sleeve 23. The guide sleeve 23 is provided with a ring structure around the outside of the support column 1 at the connection between the guide sleeve 23 and the support column 1. The inner hole of the guide sleeve 23 matches the outer diameter of the support column 1. The guide sleeve 23 and the electric hammer 2 are connected by a snap fastener.

[0030] The guide sleeve 23 guides the electric hammer 2 to move linearly up and down on the support column 1, ensuring that the direction of impact force transmission is perpendicular to the ground, and can also position the electric hammer 2 relative to the support column 1. When installing the guide sleeve 23 onto the support column 1, it only needs to be slipped onto the support column 1.

[0031] A grounding rod 3 is provided at the bottom of the electric hammer 2. The grounding rod 3 is a long rod-shaped structure with a circular cross-section. In this embodiment, both ends of the grounding rod 3 are provided with protrusions 31. The grounding rod 3 can make contact with the ground to form a good grounding effect; during drilling, it can withstand the impact force of the electric hammer 2 and transmit it to the drill bit 4.

[0032] The two ends of the grounding rod 3 have identical protrusions 31. In this embodiment, the protrusions 31 are cuboids, coaxial with the grounding rod 3, and have screw holes on their sides. The diagonal length of the protrusions 31 is less than the diameter of the grounding rod 3. The upper protrusion 31 of the grounding rod 3 can be connected to the groove at the output end of the electric hammer 2 and locked with bolts. The lower protrusion 31 of the grounding rod 3 is connected to the drill bit 4 through the connecting ring 5 and fixed with bolts.

[0033] Drill bit 4 is a conical drill bit with a spiral thread along its circumference on its surface. Drill bit 4 can drill into the soil, and a connecting platform 41 is provided at the bottom of the drill bit. The impact of the electric hammer 2 can be transmitted to drill bit 4 through grounding rod 3. Drill bit 4 can drill, loosen soil, and form a threaded channel that matches the size of grounding rod 3, thereby improving the stability of grounding resistance.

[0034] The connecting platform 41 is a cuboid with screw holes on its side. The connecting platform 41 can connect the drill bit 4 and the grounding rod 3, and is fixed by bolts to ensure that the drill bit 4 and the grounding rod 3 remain concentric and coaxial during rotation and impact.

[0035] The connecting ring 5 is a tubular ring. The inner cavity of the connecting ring 5 has the same shape as the boss 31 and the connecting platform 41. Two screw holes are provided on the outer wall 1 of the connecting ring 5 for fixing the boss 31 and the connecting platform 41. The connecting ring 5 enables a precise coaxial connection between the grounding rod 3 and the drill bit 4. The grounding rod 3 and the drill bit 4 are locked by bolts to ensure that the connection between the grounding rod 3 and the drill bit 4 does not loosen or fall off under the impact force generated by the electric hammer 2 and during rotation.

[0036] First, fix the connecting ring 5 to the bottom boss 31 of the grounding rod 3, and connect the connecting platform 41 on the top of the drill bit 4 to the bottom of the connecting ring 5. Connect the connecting ring 5 with bolts in sequence, and connect the boss 31 and the connecting platform 41 with screw holes. During disassembly and assembly, simply loosen the bolts on both sides to separate the grounding rod 3 from the drill bit 4.

[0037] In this embodiment, during installation: the bottom support column 11 of the support column 1 is fixed to the ground. The three support columns 11 ensure the stability of the support column 1. The guide sleeve 23 of the electric hammer 2 is inserted into the support column 1 and adjusted to a suitable height. The boss 31 at the upper end of the grounding rod 3 is inserted into the output end of the electric hammer 2. The boss 31 at the lower end is connected in the order of connecting ring 5 and drill bit 4, and then locked with bolts.

[0038] During construction, the electric hammer 2 is started. The impact generated by the electric hammer 2 can press the grounding rod 3 and the drill bit 4 into the ground, so that the grounding rod 3 is grounded.

[0039] By setting up support columns 11, the support column 1 can be kept balanced under different ground conditions, preventing the equipment from tipping over. The guide sleeve 23 can guide along the support column 1 to ensure that the grounding rod 3 enters the ground at a vertical angle and does not tilt. All components are connected by bolts, making them easy to carry and quick to assemble and disassemble on site.

[0040] In another embodiment, four support columns 11 are provided at the bottom of the support column 1, and the angle between the support columns 11 is 90°.
