Description

Technical Field

[0001] The utility model relates to a field, in particular to a high-efficiency ground network laying auxiliary tool. Background Art

[0002] The outdoor grounding grid of traditional substations (including railway substations such as substations, AT substations, etc.) adopts a composite grounding body with horizontal grounding body as the main body. The buried depth of the grounding grid is not less than 0.8m (1.9m deep at the cable trench), and the cross-section is 150mm 2 Copper stranded wire is used as horizontal grounding body. A single pure copper rod is used as vertical grounding body of the grounding grid. The length of the vertical grounding body is 3.5 meters, the joints are welded firmly, and the distance between grounding strips is not less than 5m.

[0003] In the past, the method of laying vertical grounding bodies mainly relied on manual use of sledgehammers to hammer pure copper grounding rods into the ground. Not only was the efficiency low, but the grounding electrodes also needed to be held by hand during the hammering process, which was not very safe. During the hammering process, the grounding electrodes were easily damaged due to uneven force, resulting in weak subsequent welding. The damaged parts needed to be cut off and re-welded. The traditional method was greatly affected by the soil quality, and the construction efficiency was greatly constrained by the soil quality. Therefore, the traditional process still has many shortcomings and needs to be improved. Utility Model Content

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] like Figures 1 to 5 As shown, it includes a pneumatic pick device 1, a fixed cylinder 2 is fixedly connected to the bottom of the output end of the pneumatic pick device 1, and a grounding electrode 6 is arranged in the fixed cylinder 2. The grounding electrode 6 is continuously reciprocated by the impact mechanism in the pneumatic pick device 11, so that the grounding electrode 6 is struck and hammered into the ground, thereby avoiding the situation where workers are easily injured when hammering the grounding electrode 6 with a sledgehammer. A limiting structure 3 is provided in the fixed cylinder 2, and limiting grooves 7 are provided on both sides of the grounding electrode 6 located in the fixed cylinder 2. The limiting structure 3 is used in combination with the limiting grooves 7 so that the pneumatic pick device 1 can be used in During the hammering of the grounding electrode 6, the grounding electrode 6 is limited to avoid the grounding electrode 6 from being separated from the fixed tube 2 at the bottom of the pneumatic pick device 1 during the hammering process. The fixed tube 2 is fixedly connected with threaded tubes 4 on both sides, and a guide structure 5 is arranged inside the threaded tube 4. The pneumatic pick device 1 is subjected to uniform force during the hammering and descending process of the grounding electrode 6 through the guide structure 5, so as to avoid the pneumatic pick device 1 from tilting and causing the grounding electrode 6 to deflect into the ground and affect the construction. Handles 8 are fixedly connected with both sides of the top of the pneumatic pick device 1, and the handles 8 are convenient for the staff to grasp the pneumatic pick device 1;

[0021] The limiting structure 3 includes a movable groove 301, in which a bidirectional threaded rod 302 is rotatably connected, and one end of the movable groove 301 extends out of the movable groove 301, and movable blocks 303 are provided at both ends of the movable groove 301, and the movable block 303 is connected to the bidirectional threaded rod 302 by a threaded structure, and the movable block 303 is fixedly connected to an arc plate 304 at one end away from the movable groove 301, and the two arc plates 304 are fixedly connected to the limiting block 305 on the opposite side, and the limiting block 305 is clamped in the limiting groove 7. After the grounding electrode 6 is inserted into the fixed tube 2, the bidirectional threaded rod is rotated 302 extends out of one end of the movable groove 301, drives the two movable blocks 303 to move in the movable groove 301, and then drives the arc plate 304 to approach the outside of the grounding electrode 6, thereby driving the limit block 305 to be clamped into the limit groove 7, and then clamping and limiting the grounding electrode 6. At the same time, a limit pin structure is provided at one end of the two-way threaded rod 302 extending out of the movable groove 301 to limit the two-way threaded rod 302, so as to prevent the vibration generated during the hammering of the grounding electrode 6 from causing the two-way threaded rod 302 to loosen, causing the grounding electrode 6 to shake and fall off;

[0022] The guide structure 5 includes a threaded column 501, and the threaded structure of the threaded column 501 is connected to the threaded tube 4. The opposite ends of the two threaded columns 501 are fixedly connected with polygonal fixed blocks 502. The two polygonal fixed blocks 502 are provided with rotating beads 503. The opposite sides of the two rotating beads 503 are fixedly connected with a guide ring 504. A guide rod 505 is inserted in the guide ring 504. The guide rod 505 is fixed to the ground. The threaded column 501 is installed through the threaded tube 4. The rotating beads 503 are used to correct the guide ring 504 so that the ring hole of the guide ring 504 is perpendicular to the ground. The guide rod 505 is inserted in the guide ring 504. When the pneumatic pick device 1 is hammered down to the grounding electrode 6, it is lowered along the guide rod 505 through the guide ring 504, thereby driving the pneumatic pick device 1 to move in a straight line, so as to avoid the pneumatic pick device 1 from being skewed during the striking process, resulting in the deviation of the grounding electrode. At the same time, the downward pressure formed by the impact mechanism of the pneumatic pick device 1 can be completely transmitted to the grounding electrode 6 to avoid the loss of kinetic energy.

[0023] The bottom of the grounding electrode 6 and the guide rod 505 are both ground plug structures, through which the grounding electrode 6 and the guide rod 505 can be conveniently plugged into the ground. The ground plug structure at the bottom of the guide rod 505 and the rod body of the guide rod 505 are fixedly connected by a limiting plate 9. The limiting plate 9 can prevent the working process of the pneumatic pick device 1 from causing the guide rod 505 to move underground, and at the same time has a certain degree of support.
