Description

Technical Field

[0001] This utility model relates to the technical field of safety equipment for power transmission lines, specifically an adjustable grounding wire hook device. Background Technology

[0002] During the construction of transmission line towers, ensuring the personal safety of workers and ensuring the proper installation of grounding wire devices are crucial safety measures. Transmission line towers come in various types and structures; however, the currently commonly used grounding wire devices employ a fixed hook design. The fixed angle of the grounding wire hook makes it difficult to adapt to the installation requirements of different towers, leading to unreliable connections in some cases. Taking straight-line towers as an example, when connecting the grounding wires to the two side phases, the fixed hook of a standard grounding wire can only be hung downwards. Due to the weight of the grounding wire itself, the hook is prone to loosening under gravity, increasing safety risks. For tension towers, the problem is even more pronounced. Due to structural limitations, the grounding wire hook can often only be temporarily attached to an adjusting plate, rather than being directly and securely fixed to the conductor. This indirect connection method has poor stability, and given the inevitable swaying and vibration of the conductor during transmission line operation, the hook is highly susceptible to accidental detachment. Such an incident not only interrupts the construction process but can also cause serious personal injury to on-site workers and even trigger a major safety accident.

[0003] Therefore, developing a grounding device that can adjust the angle of the grounding hook has become an urgent problem to be solved. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] This utility model provides embodiments: Please refer to Figures 1 to 4 An adjustable grounding wire hook device includes a double-tongue tensioning metal hook 1, a male connector 2, a female connector 3, an insulated operating rod 4, and a grounding copper wire 5. The double-tongue tensioning metal hook 1 and the male connector 2 are fastened together by a first screw 7 to form a first detachable assembly. The tail of the double-tongue tensioning metal hook 1 is engaged with the male connector 2. Figure 3 and Figure 4 As shown, the tail of the double-tongue tensioning metal hook 1 is provided with a first slot 9. The tip of the male head 2 is adapted to the first slot 9. When the tip of the male head 2 is inserted into the first slot 9, the tip of the male head 2 and the first slot 9 are connected by a first screw 7. A grounding copper wire 5 is bolted to the side of the tail of the double-tongue tensioning metal hook 1.

[0024] The female head 3 and the insulating operating rod 4 are fastened together by the second screw 8 to form a second detachable assembly, such as Figure 3 and Figure 4 As shown, the bottom of the female head 3 is provided with a first slot 14. The head of the insulating operating rod 4 is adapted to the first slot 14. Through the first slot 14, the insulating operating rod 4 and the female head 3 are snapped together. After the insulating operating rod 4 and the female head 3 are snapped together, the female head 3 and the insulating operating rod 4 are connected by a second screw 8. The tail of the insulating operating rod 4 is provided with anti-slip texture to increase the friction of the insulating operating rod 4 during use and make it easier for the user to hold. The insulating operating rod 4 can be an epoxy resin insulating operating rod.

[0025] The first detachable assembly and the second detachable assembly are detachably connected via a male connector 2 and a female connector 3. Several slots 15 are distributed on one side of the female connector 3, and angle markings 12 are provided on the female connector 3. The angle markings 12 and slots 15 are in a one-to-one correspondence. A corresponding locking post 13 is provided on one side of the male connector 2, which can be axially inserted into the slot 15 to form a pre-position. Several locking posts 13 are circumferentially distributed on the male connector 2. The top locking post 13 has a positioning mark (such as an arrow, color ring, or number) on its surface to distinguish it from other locking posts 13. Through the orientation mark of the top locking post 13, the user can quickly identify the assembly reference direction, ensuring that the male connector 2 and the female connector 3 are accurately connected within a preset angle range, thus achieving accurate adjustment of the adjustable grounding hook angle.

[0026] Both the male head 2 and the female head 3 have threaded holes 16 in the middle. The butterfly connecting screw 6 is adapted to the threaded holes 16. After the female head 3 and the male head 2 are radially limited by the engagement of the locking post 13 and the locking groove 15, they are tightened by the butterfly connecting screw 6.

[0027] Example 2

[0028] like Figure 5 As shown, the difference between Embodiment 2 and Embodiment 1 is that the male head 2 is provided with a first locking structure. The first locking structure is used to lock the male head 2 and the double-tongue tensioning metal hook 1, so that when the first screw 7 is loose, the male head 2 and the double-tongue tensioning metal hook 1 can still be reliably connected, ensuring the reliability of this application. The first locking structure includes a Z-shaped locking rod 11 movably connected to the male head 2. The top of the male head 2 is provided with a movable cavity 20 adapted to the locking rod 11. The locking rod 11 is movably connected to the inner cavity of the movable cavity 20. The locking rod 11 is connected to the male head 2 through a first spring 21. Under the action of the rebound force of the first spring 21, the bottom end of the locking rod 11 can extend to the outside of the male head 2. When the male head 2 and the female head 3 are engaged, the female head 3 can squeeze the bottom end of the locking rod 11, so that the locking rod 11 can move within the movable cavity 20. The inner wall of the first slot 14 is provided with a locking groove 10 adapted to the top end of the locking rod 11. When the male head 2 is engaged with the double-tongue tensioning metal hook 1, when the bottom end of the locking rod 11 moves under the pressure of the female head 3, the top end of the locking rod 11 can move into the locking groove 10, thereby realizing the automatic locking of the male head 2 and the double-tongue tensioning metal hook 1.

[0029] Example 3

[0030] like Figure 5As shown, the difference between Embodiment 3 and Embodiment 1 is that the top of the female head 3 is provided with a second locking structure. The second locking structure is used to lock the female head 3 and the insulating operating rod 4, thereby improving the reliability of the connection between the female head 3 and the insulating operating rod 4. The second locking structure includes an L-shaped locking block 18. The top of the female head 3 is provided with a second movable cavity 22. The locking block 18 is movably connected to the inner cavity of the second movable cavity 22. The top of the locking block 18 extends to the outside of the second movable cavity 22. The locking block 18 is connected to the female head 3 through a second spring 17. The top of the insulating operating rod 4 is provided with a second slot 19 that matches the horizontal end of the locking block 18. When the female head 3 and the insulating operating rod 4 are engaged, the horizontal end of the locking block 18 is aligned with the second slot 19. When the male head 2 and the female head 3 are engaged, the bottom end of the male head 2 can press the top of the locking block 18, allowing the locking block 18 to move. The horizontal end of the locking block 18 can move into the second slot 19, achieving automatic locking between the female head 3 and the insulating operating rod 4. When the pressure on the locking block 18 is released, the locking block 18 can automatically reset under the action of the rebound force of the second spring 17, releasing the lock between the female head 3 and the insulating operating rod 4.

[0031] As can be seen from the above description, this application has the following beneficial effects: 1. It is easy to operate and flexible to use, which greatly reduces the operational risks for high-altitude workers and improves the safety of working on towers.

[0032] 2. Highly adaptable: With an adjustable device, the grounding wire can adapt to various tower types, and the angle can be adjusted for different locations for installation.

[0033] 3. Easy to carry and simple to install, installation is completed by tightening the mounting screws.

[0034] 4. Facilitates warehousing and storage. The grounding wire hook and the insulating rod can be stored separately, which is conducive to the standardized and qualified storage and placement of tools and equipment.

[0035] In summary: Before using this adjustable grounding wire hook device, before attaching the grounding wire, combine the double-tongue tensioning metal hook 1 with the epoxy resin insulated operating rod 4. That is, combine the male head 2 at the tail of the double-tongue tensioning metal hook 1 with the female head 3 at the head of the epoxy resin insulated operating rod 4, and connect them with the butterfly connecting screw 6 to form an adjustable grounding wire hook device. The operator can adjust the angle between the double-tongue tensioning metal hook 1 and the insulated operating rod 4 according to the actual situation and by observing the on-site transmission line conductor erection method. The specific operation is as follows: after unscrewing the butterfly connecting screw 6 and disconnecting the male head 2 and the female head 3, the operator separates the male head 2 and the female head 3, aligns the locking post 13 with the corresponding angle locking slot 15, and then locks the locking post 13 with the locking slot 15. Finally, use the butterfly connecting screw 6 to connect the male head 2 and the female head 3.

[0036] In use, the double-tongue tensioning metal hook 1 is tightly secured to the conductor. The grounding copper wire 5, which is installed on the outer side of the double-tongue tensioning metal hook 1, is connected according to the principle of connecting the grounding end first and then the conductor end. The specific steps are as follows: the upper end of the grounding copper wire 5 is connected to the grounding copper wire 5 connecting bolt. Before hanging the metal grounding hook on the transmission line, the lower end of the grounding copper wire 5 must first be connected to the transmission tower for grounding.
