[0024] The utility model will be further described in detail below in combination with embodiments.

[0025] The specific embodiment of the grounding wire construction device in the power engineering provided by the utility model:

[0026] Please refer to Figs. 1-3 , the grounding wire construction device in the power engineering, including cylinder 1, cylinder 1 upper end has opening, lower end is closed, the lower end wall of cylinder 1 is vertically slidably connected with hammer 3 in the middle part, hammer 3 passes through the lower end wall of cylinder 1, the lower end wall of cylinder 1 has the through hole matched with hammer 3, in some embodiments, sealing ring can be arranged in the through hole, to ensure sealing property, the vertical section of hammer 3 across the centre line is I-shaped.

[0027] Cylinder 1 is provided with piston 2, piston 2 upper side is connected with the drive assembly of driving piston 2 reciprocating movement, piston 2 reciprocating movement compresses air in cylinder 1, and the periodic change of air pressure in cylinder 1 drives hammer 3 reciprocating movement, and its principle is similar to the opening impact mode of electric hammer.

[0028] The driving assembly comprises a reduction motor 6, a bevel gear set 7, a rotating disc 8 and a connecting rod 9, the connecting rod 9 is hinged between the edge of the rotating disc 8 and the upper side of the piston 2, and the reduction motor 6 is connected with the rotating disc 8 through the bevel gear set 7. The upper side of the cylinder 1 is provided with a transmission box 10, and the bevel gear set 7 and the rotating disc 8 are both rotatably installed in the transmission box 10; the reduction motor 6 is installed on the upper side of the transmission box 10.

[0029] The output shaft of the reduction motor 6 is connected with the bevel gear set 7 through the upper wall of the transmission box 10, the bevel gear set 7 comprises two bevel gears whose center lines are perpendicular, the bevel gear set 7 changes the direction of the output torque of the reduction motor 6 and transmits it to the rotating disc 8. The rotating disc 8, the connecting rod 9 and the piston 2 constitute a slider-crank mechanism, and the reciprocating movement of the piston 2 is realized.

[0030] The cylinder 1 is connected with a rectangular frame-shaped handle 11 on the outside of the middle part, the lower part of the rectangular frame-shaped structure of the handle 11 has a gap, and the cylinder 1 corresponds to the position of the gap. A horizontal U-shaped reinforcing rod 12 is connected to one side of the middle part of the handle 11, and the reinforcing rod 12 is supported on the lower side of the reduction motor 6. The height of the handle 11 is higher than the upper end of the reduction motor 6, which plays a certain protective role for the device, and a rubber sleeve is arranged on the outside of the vertical part of the handle 11 to improve the comfort of holding.
