Spiral elevating ground wire drill device

Abstract

The invention provides a spiral elevating ground wire drill device, which comprises a transverse plate, a hollow circular pipe, a clamping device and a water storage tank, wherein an external thread is arranged in the outer circumferential side wall of the hollow circular pipe; a threaded through hole matched with the external thread is arranged in the middle part of the transverse plate; a pair of support legs is symmetrically arranged at two ends of the lower bottom surface of the transverse plate; a pair of thrust levers is symmetrically arranged at the upper end of the hollow circular pipe; and the water storage tank is arranged at the outer side of one support leg. When a ground wire drill is extracted by using the device, the ground wire drill is located at the center position of the whole device, so that the phenomenon of deflection of the whole device in the extraction process is avoided. Meanwhile, the ground wire drill is extracted by the device in a manner of elevating while rotating, so that the friction force of the ground wire drill in the vertical direction is effectively decomposed in the rotating process, the ground wire drill is more easily extracted and the extraction working strength is further reduced.

Description

technical field [0001] The invention relates to an auxiliary tool for electric power construction operations, in particular to a spiral lifting ground wire brazing device. Background technique [0002] At the electric power construction site, in order to ensure the safety of electric power construction, it is necessary to temporarily ground the wires that may be touched during the construction process. Temporary grounding of wires is generally to connect the wires with the ground wire nailed into the ground. The ground wire generally consists of a drill cap and a straight rod set under the drill cap. To ensure reliable grounding, the straight rod part of the ground wire needs to be It is nailed into a deep position below the ground, because the straight rod part of the ground wire is nailed deeply, which makes it very difficult to pull out the ground wire. [0003] The Chinese patent with the notification number CN 102447231B discloses a ground wire brazing puller, although...

The ground wire generally consists of a drill cap and a straight rod set under the drill cap. To ensure reliable grounding, the straight rod part of the ground wire needs to be It is nailed to a deep position below the ground, because the straight rod of the ground wire is nailed deeply, which makes it very difficult to pull out the ground wire

[0003] The Chinese patent with the notification number CN 102447231B discloses a ground wire brazing puller, although the puller can successfully pull out the ground wire brazing, but during the pulling process, since the ground wire brazing is located on the side of the whole device , so that the shell is subjected to a large moment, it is easy to cause the whole device to be skewed to the position of the ground wire, and at the same time, due to the long ground wire, the height of the entire device is also large, making the device inconvenient to carry
