Description

Technical Field

[0001] This utility model relates to the field of crimping technology, specifically to a crimping device for grounding electrode and grounding down conductor. Background Technology

[0002] In recent years, the promulgation of relevant laws, regulations, and safety management provisions, such as the "Fire Protection Law of the People's Republic of China" and local safety production regulations, has put forward clear requirements for hot work operations. Relevant approval procedures must be completed and corresponding fire safety measures must be taken before hot work construction activities can be carried out in sensitive areas. The selection of tower sites and lines for power transmission lines mostly requires entering hot work sensitive areas. Grounding devices are an essential part of lightning protection grounding for power transmission lines. Currently, most grounding devices require hot work construction, which not only involves cumbersome procedures but also increases on-site construction risks.

[0003] Therefore, to reduce construction time and costs and ensure a safe construction environment, the grounding down conductor and flat steel connection in the grounding device are first welded in the factory and then transported to the site. Upon arrival, they are connected to the horizontal grounding body via hydraulic crimping, thus eliminating the need for hot work. Existing hydraulic crimping devices generally use hydraulic clamps to squeeze the grounding body with a certain opening, thereby crimping and connecting the grounding down conductor placed inside. This method usually requires two people to perform the crimping operation: one person holds the hydraulic clamps, and the other inserts the grounding down conductor into the opening of the grounding body and places the opening in the crimping position of the hydraulic clamps. However, this two-person operation requires twice the manpower, which undoubtedly increases the operational burden on enterprises in the context of rising labor costs. Utility Model Content

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Example: Please refer to Figure 1-4A crimping device for grounding electrodes and grounding down conductors includes a hydraulic body 10, a beam plate 6 fixed to the hydraulic body 10, a first crimping block 7 installed at the end of the beam plate 6, and a second crimping block 11 installed on the output end of the hydraulic body 10. It also includes a support rod 3 installed at the bottom of the beam plate 6, with an elastic clamping assembly detachably connected to the support rod 3 for clamping the non-crimped portion of the grounding electrode 1. When the grounding electrode 1 is clamped, the crimped portion of the grounding electrode 1 is located between the first crimping block 7 and the second crimping block 11, with the opening of the crimped portion facing the second crimping block 11. The arc plate 5 at the crimped portion of the grounding electrode 1 abuts against the first crimping block 7 to prevent rotation of the grounding electrode 1 during the crimping process. The hydraulic body 10 can be in the form of common hydraulic clamps; and the grounding electrode 1 can be cross-shaped, straight, or... One type of T-shape facilitates connection with multiple grounding leads 9. In this embodiment, the crimping of the cross-shaped grounding body 1 is taken as an example. When it is necessary to crimp the grounding body 1 and the grounding lead 9, the operator only needs to clamp the grounding body 1 with the elastic clamping component first. Then, one hand can insert the grounding lead 9 into the opening of the grounding body 1 and make it fit tightly against the arc plate 5. Then, the other hand can start the hydraulic clamp. Therefore, the crimping device in this utility model only requires one person to start, eliminating the disadvantages of requiring two people to operate in the past and reducing costs. In this embodiment, the opening size of the grounding body 1 and the cavity size of the first crimping block 7 and the second crimping block 11 used to compress the opening into an arc are not specifically limited. Users can choose according to the actual situation.

[0024] In this embodiment, the elastic clamping assembly includes a support block 4 detachably connected to the support rod 3, a square rod 12 slidably connected to and passing through the support block 4, and a movable block 8 fixed to the top of the square rod 12. A support plate 14 is provided at the bottom of the square rod 12. A spring 13 is sleeved on the square rod 12 between the support plate 14 and the support block 4. The support block 4 and the movable block 8 are provided with cavities for restricting the movement of the grounding body 1. The movable block 8 and the support block 4 clamp the grounding body 1 under the action of the spring 13. The sliding connection adopts a transition fit. When it is necessary to clamp the grounding body 1, the movable block 8 is first pulled up, at which point the spring 13 is compressed, and then the grounding body 1 can be clamped. The grounding body 1 is placed in the cavity of the support block 4. Then, the moving block 8 is released, and the spring 13 returns to its original position, thus clamping the grounding body 1. In addition, the top of the moving block 8 is provided with a pull ring 2, which is convenient for the user to operate the moving block 8. The bottom of the support block 4 is fixed with a vertical rod into which the support rod 3 is inserted. The vertical rod and the support rod 3 are provided with aligned through holes. A V-shaped spring piece 19 is installed on the inner hole 21 of the vertical rod. The tip of the V-shaped spring piece 19 passes through the aligned through hole, which is convenient for the replacement of the elastic clamping component and enables the crimping of more models of grounding bodies 1. When replacing, simply press the tip to push the tip away from the through hole on the support rod 3, and then the elastic clamping component can be pulled out for replacement.

[0025] Besides the possible differences in the approximate dimensions of the grounding electrode 1, the length of the crimped joint also varies, as does the distance from the crimped joint to the center of the grounding electrode 1. Therefore, in this embodiment, the support rod 3 is provided with a dovetail groove 20, and the bottom of the beam plate 6 is provided with a boss that mates with the dovetail groove 20. This ensures the stability of the support rod 3 during lateral adjustment, thus adapting to crimping joints of different lengths and different distances from the crimped joint to the center of the grounding electrode 1. The bottom of the support rod 3 is provided with three threaded holes 18. When the wing bolt 17 is tightened, its end is pressed against the boss, preventing the support rod 3 from moving during use. The distance between two adjacent threaded holes 18 is less than the width of the beam plate 6, thereby increasing the adjustment range of the support rod 3 while ensuring that the support rod 3 can be fixed.

[0026] In this embodiment, the support rod 3 is provided with a fin plate 16, and the bottom of the beam plate 6 is provided with a limiting protrusion 15 aligned with the fin plate 16 to prevent the support rod 3 from slipping out; the first pressing block 7 is detachably connected to the beam plate 6, and the second pressing block 11 is detachably connected to the output end of the hydraulic body 10. The detachable connection is made by bolt connection. Users can replace the pressing blocks with different cavities as needed to achieve different pressing methods or to press grounding bodies 1 and grounding leads 9 of different sizes; the bottom of the second pressing block 11 is provided with two support seats, which are slidably connected to the beam plate 6. The slidable connection can be in the form of a transition fit.

[0027] Working principle: When it is necessary to crimp the grounding body 1 and the grounding down conductor 9, the operator only needs to pull up the moving block 8 through the pull ring 2. At this time, the spring 13 is compressed. Then, the grounding body 1 is placed in the cavity of the support block 4. Then, the moving block 8 is released, and the spring 13 returns to its original position while clamping the grounding body 1. Then, the operator can insert the grounding down conductor 9 into the opening of the grounding body 1 with one hand and make it close to the arc plate 5. Then, the operator can activate the hydraulic clamp with the other hand to achieve the crimping of the grounding body 1 and the grounding down conductor 9. Therefore, the crimping device in this application only requires one person to use, eliminating the disadvantages of requiring two people to operate in the past and reducing costs.
