Description
Technical Field
[0001] The utility model relates to the technical field of live working, in particular to an overhead line grounding device. Background Art
[0002] According to the provisions of the State Grid Corporation's power safety work regulations, after the line is verified to have no voltage, a grounding wire should be installed immediately and the three phases should be short-circuited. During live work, the work sections of each work shift and the branch lines that may supply power to the work sections of the power outage lines should be tested for power and installed with working grounding wires. Installing a grounding wire is one of the five technical measures to ensure safety, which is used to prevent the line from supplying power backwards during power outage maintenance work, causing serious consequences.
[0003] When overhead lines are under maintenance, grounding wires need to be installed. Grounding wires used in normal work all have temporary grounding bodies. Before installation, grounding rods need to be driven into the ground. Then workers climb the poles to test the electricity. After that, the grounding wires are installed on the grounding rods. Currently, when driving the grounding rods, additional tools are needed to drive them into the ground. They need to be driven into the ground to a certain depth, which is time-consuming. Once the grounding rods are driven deep into the ground, although they have good stability, it is difficult to remove the grounding rods at a later stage. If the grounding rods are driven shallowly into the ground, their stability is poor and there are certain safety hazards. Therefore, an overhead line grounding device is proposed to address the above problems. Utility Model Content

[0009] Pedals are fixedly connected to both sides of the bottom of the hollow cylinder.
[0010] During the maintenance of overhead lines, it is necessary to hang ground wires. The ground wires used in normal work all have temporary grounding bodies. Before hanging, the ground rod needs to be driven into the ground, and then the staff climbs the pole to test the electricity, and then hangs the ground wire on the ground rod, and finally the staff goes down the pole. At present, when driving the ground rod, it needs additional tools to drive it into the ground, and it needs to be driven into the ground to a certain depth, which is time-consuming.

The handle drives the first threaded rod to rotate, and the first threaded rod drives the second threaded rod to rotate, so that the second threaded rod can drive the drill bit to move downward, and the second threaded rod is drilled into the soil through the drill bit. This setting can easily drill it into the soil and has good stability. When disassembling, the second threaded rod and the drill bit can be driven out of the soil by reversing the handle. Installation and disassembly are very simple, and the equipment is easy to use.

[0012] As an optional solution of the overhead line grounding device described in the utility model, the support plates are staggered in distribution up and down, and the rejection block on one side of the support plate is inclined.
[0013] When the second threaded rod is reversed and reset, the support plate and the rejecting block are provided, and the rejecting block rejects the soil in the thread groove of the second threaded rod, thereby ensuring that the inside of the hollow cylinder is clean and the equipment can be recycled.
[0014] As an optional solution of the overhead line grounding device described in the utility model, wherein: a lower pressure ring is provided on the outer side of the second threaded rod, a connecting rod is fixedly connected to the top of the lower pressure ring, the outer side of the connecting rod is slidably connected to the hollow cylinder, and an extrusion ring is fixedly connected to the top of the connecting rod.

[0016] When removing soil, the squeezing ring is pressed down, and the squeezing ring can drive the connecting rod to move, and the connecting rod drives the pressing ring to move on the outside of the second threaded rod. At this time, the soil that has not fallen off can be squeezed downward to ensure the normal use of the equipment, and the set spring can ensure that the squeezing ring is reset to ensure the next extrusion use.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] When the utility model is used, it is placed in a suitable position, the foot steps on the pedal, and the handle is turned, so that the handle drives the first threaded rod to rotate, and the first threaded rod drives the second threaded rod to rotate, so that the second threaded rod drives the drill bit to move downward, and the drill bit makes the second threaded rod drill into the soil. This arrangement can easily drill into the soil and has good stability. When disassembling, the second threaded rod and the drill bit can be driven to separate from the soil by reversing the handle. The installation and disassembly are very simple, and the equipment is convenient to use.
[0019] When the second threaded rod is reversed and reset, the support plate and the rejecting block are provided, and the rejecting block removes the soil in the thread groove of the second threaded rod, so that the inside of the hollow cylinder can be kept clean and the equipment can be recycled;
[0020] When removing the soil, the squeezing ring is pressed down, and the squeezing ring can drive the connecting rod to move, and the connecting rod drives the pressing ring to move outside the second threaded rod. At this time, the soil that has not fallen off can be squeezed downward to ensure the normal use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
