Abstract
The invention relates to a manual grounding round steel bending tool and a bending method thereof, and belongs to the technical field of power construction tools and construction processes. The tool comprises upper angle steel, lower angle steel and an operating rod with one end hinged between the upper angle steel and the lower angle steel, wherein two first bolts are arranged at intervals in the length direction of the horizontal plane of the angle steel, and the tops of the two first bolts are sleeved with steel pipes, one end of the operating rod is provided with an outer side connecting hole for allowing one first bolt to penetrating and an inner side connecting hole for allowing a second bolt to be installed, the second bolt is sleeved with a bearing, a bolt hole is formed in the middle of the vertical face of the lower angle steel, and a third bolt used for fastening the lower angle steel to a joint of an iron tower grounding lead is inserted into the bolt hole. According to the tool, before a round steel grounding body is connected with an iron tower, a round steel downlead can be regularly bent according to the field foundation and the size of a tower body, the problem that the grounding round steel construction technology is not standard is solved, and potential safety hazards can be greatly reduced.
Description
technical field [0001] The invention relates to a manual grounded round steel bending tool and a bending method thereof, belonging to the technical field of electric power construction tools and construction techniques. Background technique [0002] Every base tower of the power line needs to be connected with a grounding device, and the existing grounding device is basically a round steel grounding body. During the foundation construction, the round steel grounding body needs to be pre-buried and laid around the foundation, and the round steel lead wire and the round steel down lead wire are reserved for welding, and the grounding channel is formed by connecting the ground connecting plate with the tower. When the angle steel tower and steel pipe pole are connected with the round steel down conductor, the round steel down conductor cannot be close to the tower body and the foundation due to the influence of the outer edge of the tower foundation, see the attached figure 1 ...
