Portable grounding rod installation power machine device

Abstract

The invention discloses a portable grounding rod installation power machine device, and the device comprises a steel cylinder with the lower end being opened, a spring at the top of an inner cavity of the steel cylinder, an iron core which can move up and down in the cavity of the steel cylinder and has the width being greater than the diameter of a lower opening of the steel cylinder, and an iron hammer which is fixedly connected with the bottom end of the iron core, wherein the width of the iron hammer is less than the diameter of the lower opening of the steel cylinder. The left and right sides of the inner wall of the steel cylinder are provided with a guide rail pair, and an inner side of the guide rail pair is provided with a rolling ball parallel to an axis. The outer layer of the guide rail pair is provided with a coil in an axis direction in a winding manner. Hall sensors are arranged at intervals from the bottom end of the inner cavity at an inner side of the guide rail pair at one side and at a gap between the iron core and the inner wall of the steel cylinder. The device can give an enough impact force to the iron hammer in a limited height range, thereby achieving the mechanical automatic installation of the grounding rod. The device is simple in operation, saves a large amount of labor force and a large-size excavator, is light in overall weight, is portable, and can be conveniently used in various construction environments.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance equipment, in particular to a portable ground rod installation power mechanical device. Background technique [0002] The grounding device occupies an extremely important position in the grounding protection of the power equipment line of the distribution network. When the power equipment is subjected to induced overvoltage, short-circuit overvoltage, and induced lightning strike, the grounding current generated instantaneously is very large, and the grounding electrode can quickly spread the grounding current. into the ground, avoiding the breakdown damage of power equipment and maintaining the normal operation of power line equipment. Generally, the grounding resistance of power line equipment is less than 10 ohms. The smaller the grounding resistance, the stricter the requirements for the material of the grounding electrode and the quality of construction and installation....

AI Technical Summary

Problems solved by technology

When the ground electrode is driven into the ground to a depth of less than 3 meters, manual installation is generally used. This method cannot ensure that the ground rod is vertically pressed into the ground, and because the ground rod will swing when held by hand, there are certain slits around the ground rod. The reason for the increase in the resistance value is often a problem here. It is necessary to repeatedly beat the surrounding soil or fill the resistance reducing agent several times to reduce the resistance value, resulting in slow installation speed and low efficiency.

[0003] In addition, when the grounding rod needs to be driven into the ground to a depth greater than 3 meters, especially when the installation depth is required to be 6-10 meters, the construction workers are very laborious and cannot drive the grounding rod into the ground.

In this case, the construction unit must first use the excavator to dig out the required vertical deep pit with the help of large-scale excavation equipment, then put the grounding electrode into the excavated deep pit, and use soil backfill to compact the excavated area. This construction method is very It is not economical, plus large machinery generally has a large power, large volume, and is relatively heavy. It requires trained and qualified professional and skilled workers to operate and use it. The cost of running such equipment is also very high.

On the other hand, the roads in many construction sites are narrow, and it is difficult for excavation machinery to enter and cannot be used for construction. Even in places with small working spaces, remote mountainous areas and the wild, large machinery and equipment cannot be used for construction.

[0004] At the present stage, there is no mature mechanical equipment that is convenient to operate, safe and reliable in the installation and use of grounding rods, which can directly drive the grounding rods into the ground
