Description

Technical Field

[0001] This utility model relates to the technical field of ground wire insulating rods, and in particular to a multifunctional ground wire insulating rod hook. Background Technology

[0002] Grounding rods, also known as grounding bars or grounding operating rods, are key tools for ensuring personal safety during power outage maintenance work in power systems. These long rods, made of high-strength insulating materials, are mainly used to safely connect and disconnect temporary grounding wires on high-voltage lines or equipment that have been confirmed to be de-energized.

[0003] In the early days of power work, although the safety principle that power lines must be grounded before being de-energized was established, the use of simple hooks for tying the wires made them very easy to come loose due to wind, line vibration, or accidental contact. This not only caused the safety grounding to fail, but could also lead to electric shock to people on the other end of the grounding wire, creating a serious safety hazard.

[0004] Currently available grounding wire insulating rod hooks consist of a hook, jaws, and a connecting interface. In use, the hook is connected to the insulating rod via the connecting interface. By holding the insulating rod, the hook is raised to the target conductor position, and the jaws engage with the conductor to complete the grounding process. However, since the hook only engages with the cable via the jaws, it can loosen under external force, causing the insulating rod to detach. To address this issue, existing technology uses a locking mechanism to secure the hook to the cable. However, this design requires manual operation, necessitating close proximity and climbing, which reduces the practicality of the insulating rod hook. Utility Model Content

The driven bevel gear meshes with the driving bevel gear. Slider blocks are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod. A conductive plate is provided at the bottom of the adjacent side of the two sliders.

[0008] As a further description of the above technical solution:

[0009] The connecting mechanism includes a plug-in block, which is fixedly connected to the top of the conductive rod. The plug-in block has slots on all four sides of its outer perimeter. A hollow column extends through the top of the plug-in block. A rotating rod is rotatably connected to the top inner side of the hollow column. A support plate is fixedly connected to the bottom of the rotating rod. Curved grooves are formed on all four sides of the support plate. A plug-in post is slidably connected to the inner side of the curved grooves. A locking block is fixedly connected to the bottom of the plug-in post, engaging with the slots. A reset component is located in the upper middle part of the inner side of the hollow column, and a control component is located on the top outer side of the rotating rod.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes a fixing ring, which is fixedly connected to the upper inner part of the hollow column. A torsion spring is provided on the lower outer part of the rotating rod, and the upper and lower ends of the torsion spring are fixedly connected to the fixing ring and the support plate, respectively.

[0012] As a further description of the above technical solution:

[0013] The control component includes a connecting rod, which is fixedly connected to the top outer side of the rotating rod. A groove is provided on the top outer side of the hollow column, and a lever is fixedly connected to the outer side of the connecting rod through the groove.

[0014] As a further description of the above technical solution:

[0015] The outer side of the slider is slidably connected to the inside of the hollow plate, and the top of the outer side of the support block is rotatably connected to the hollow tube.

[0016] As a further description of the above technical solution:

[0017] The fixing mechanism also includes screws, two of which are threadedly connected to adjacent sides of the two conductive plates, and the two screws pass through the corresponding conductive plates and are threadedly connected to the slider.

[0018] As a further description of the above technical solution:

[0019] The fixing mechanism also includes a fixing block, which is fixedly connected to the top of the hollow tube, and a placement hook is fixedly connected to the top of the fixing block.

[0027] 1. In this utility model, by placing a hollow plate on the cable and rotating the conductive rod, the conductive rod drives the support block to rotate through the hollow column. The transmission rod then drives the active bevel gear to rotate. Through the meshing transmission of the active bevel gear and the driven bevel gear, the bidirectional threaded rod is driven to rotate, which drives the sliders on both sides to move towards the middle at the same time, so that the conductive plates on both sides are tightly attached to the cable. This makes the hook fixed to the cable, making the fixing work more convenient and improving the practicality of the insulating rod hook.

[0028] 2. In this utility model, the paddle drives the rotating rod to rotate through the connecting rod, which in turn drives the support plate to rotate. The support plate pushes the plug-in column to move through the curved groove, which in turn drives the locking block to move, causing the locking block to disengage from the locking groove, thereby pulling the plug-in block out of the hollow column. This allows the hook to be easily removed from the top of the conductive rod for storage, improving the convenience of the insulating rod hook. Attached Figure Description

[0037] 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.

[0038] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a multifunctional ground wire insulating rod hook, including a hollow column 1, a conductive rod 4 is provided on the lower side of the hollow column 1, a fixing mechanism 2 is provided on the top of the hollow column 1, the fixing mechanism 2 is used to facilitate the connection of the hook to the cable, and a connecting mechanism 3 is provided on the inner side of the hollow column 1, the connecting mechanism 3 is used to facilitate the disassembly and installation of the hook.

[0039] The fixing mechanism 2 includes a support block 21, which is fixedly connected to the top of the hollow column 1. A hollow tube 22 is provided on the upper side of the support block 21. A transmission rod 23 is rotatably connected to the top of the support block 21. When the support block 21 is rotated by the conductive rod 4, it will further drive the transmission rod 23 to rotate. A drive bevel gear 24 is fixedly connected to the top of the transmission rod 23, which will drive the drive bevel gear 24 to rotate. A hollow plate 25 is fixedly connected to the left side of the hollow tube 22. A bidirectional threaded rod 26 is rotatably connected to the top of the inner side of the hollow plate 25. The right end of the bidirectional threaded rod 26 passes through the hollow plate 25 and the hollow tube 22 in sequence and is fixedly connected. A driven bevel gear 27 is connected to a driving bevel gear 24. When the driving bevel gear 24 rotates, the driven bevel gear 27 will drive the bidirectional threaded rod 26 to rotate. The outer wall of the bidirectional threaded rod 26 is threaded with sliders 28 on both the left and right sides. The bottom of the adjacent side of the two sliders 28 is provided with conductive plates 29. When the bidirectional threaded rod 26 rotates, the sliders 28 will drive the conductive plates 29 to move. The outer side of the sliders 28 is slidably connected to the inside of the hollow plate 25. The sliders 28 can only slide on the inside of the hollow plate 25, so that the sliders 28 will not deflect. The top of the outer side of the support block 21 is rotatably connected to the hollow tube 22.

[0040] Specifically, in use, the hollow plate 25 is first placed on the cable that needs to be grounded. Then, the conductive rod 4 is rotated. The rotation of the conductive rod 4 will drive the support block 21 to rotate through the hollow column 1. When the support block 21 rotates, it will drive the active bevel gear 24 to rotate through the transmission rod 23. Since the active bevel gear 24 and the driven bevel gear 27 mesh with each other, the rotation of the active bevel gear 24 will drive the driven bevel gear 27 to rotate, which in turn drives the bidirectional threaded rod 26 to rotate. As the bidirectional threaded rod 26 rotates, the sliders 28 on both sides will move towards the center at the same time, which will push the conductive plates 29 on both sides to retract inward and clamp the cable. By rotating the conductive rod 4 alone, the hook and the cable can be fixed. And by fixing the conductive plates 29 on both sides, the hook and the cable can be firmly fixed and there will be no poor contact.

[0041] Reference Figure 3 , Figure 5 and Figure 6The connecting mechanism 3 includes a plug-in block 31, which is fixedly connected to the top of the conductive rod 4. The plug-in block 31 has slots 32 on all four sides of its outer perimeter. The top of the plug-in block 31 passes through the hollow column 1. A rotating rod 33 is rotatably connected to the top of the inner side of the hollow column 1. A support plate 34 is fixedly connected to the bottom of the rotating rod 33. Curved grooves 35 are formed on all four sides of the outer perimeter of the support plate 34. A plug-in post 36 is slidably connected to the inner side of the curved grooves 35. A locking block 37 is fixedly connected to the bottom of the plug-in post 36, engaging with the slots 32. A reset assembly 38 is provided in the upper middle part of the inner side of the hollow column 1. A control assembly 39 is provided in the top of the outer side of the rotating rod 33. The reset assembly 38 includes a fixing ring 381. Ring 381 is fixedly connected to the upper middle part of the inner side of hollow column 1. Torsion spring 382 is provided on the lower middle part of the outer side of rotating rod 33. The upper and lower ends of torsion spring 382 are fixedly connected to fixed ring 381 and support plate 34 respectively. Control component 39 includes connecting rod 391, which is fixedly connected to the top outer side of rotating rod 33. A sliding groove 392 is provided on the top outer side of hollow column 1. The outer side of connecting rod 391 passes through sliding groove 392 and is fixedly connected to paddle 393. Connecting mechanism 3 also includes guide rod 310. Multiple guide rods 310 are fixedly connected to the inner periphery of hollow column 1. The outer side of guide rod 310 is slidably connected to block 37. One end of guide rod 310 is fixedly connected to limit piece 311.

[0042] Specifically, when the hook and conductive rod 4 need to be stored separately, the lever 393 is turned, which drives the rotating rod 33 to rotate via the connecting rod 391. The rotation of the rotating rod 33 drives the support plate 34 to rotate. When the support plate 34 rotates, the curved groove 35 pushes the insertion post 36 to move. The insertion post 36 then drives the locking block 37 to move, causing the locking block 37 to disengage from the locking state of the slot 32. This allows the insertion block 31 to be pulled out of the hollow column 1, thus separating the hook from the top of the conductive rod 4 for storage. When it is necessary to reassemble, the insertion block 31 is simply inserted back into the hollow column 1. The torsion spring 382 will push the support plate 34 to rotate in the opposite direction, causing the locking block 37 to re-engage with the slot 32, thereby locking the insertion block 31.

[0043] Reference Figure 3 and Figure 4 The fixing mechanism 2 also includes screws 210. Two screws 210 are threadedly connected to adjacent sides of two conductive plates 29 respectively. The two screws 210 pass through the corresponding conductive plates 29 and are threadedly connected to the slider 28. The fixing mechanism 2 also includes a fixing block 211. The fixing block 211 is fixedly connected to the top of the hollow tube 22. A placement hook 212 is fixedly connected to the top of the fixing block 211. The hook can be hung up when storing.

[0044] Specifically, the conductive plate 29 can be replaced by removing screw 210, so that the hook can be adapted to cables of different sizes. When storing, the hook 212 can be used to hang the hook for easy storage.

[0045] Reference Figure 1 and Figure 2 An insulating layer 5 is fixedly connected to the outer side of the conductive rod 4. A rubber layer 6 is fixedly connected to the lower middle part of the outer side of the insulating layer 5. A fixing plate 7 is fixedly connected to the bottom of the conductive rod 4. A grounding nail 8 is fixedly connected to the bottom of the fixing plate 7. The grounding nail 8 is used to facilitate the grounding of the conductive rod 4.

[0046] Specifically, the insulation layer 5 prevents workers from touching the conductive rod 4 during grounding, and the rubber layer 6 prevents workers from slipping when picking up the insulation rod. By inserting the grounding nail 8 into the soil, the grounding of the conductive rod 4 can be easily completed.

[0047] Working principle: When using the insulating rod hook, first place the hollow plate 25 on the cable that needs to be grounded, and at the same time rotate the conductive rod 4. The conductive rod 4 will drive the support block 21 to rotate through the hollow column 1. When the support block 21 rotates, it will drive the active bevel gear 24 to rotate through the transmission rod 23. Since the driven bevel gear 27 meshes with the active bevel gear 24, when the active bevel gear 24 rotates, the driven bevel gear 27 will drive the bidirectional threaded rod 26 to rotate. When the bidirectional threaded rod 26 rotates, it will drive the sliders 28 on both sides to move towards the middle at the same time, thereby driving the conductive plates 29 on both sides to fit tightly with the cable. The hook can be fixed by simply rotating the conductive rod 4, making the fixing work more convenient. And by fixing the conductive plates 29 on both sides, the hook can be firmly fixed to the cable.

[0048] Furthermore, when it is necessary to store the hook and the conductive rod 4 separately, the lever 393 is turned. The lever 393 can drive the rotating rod 33 to rotate through the connecting rod 391. The rotating rod 33 will then drive the support plate 34 to rotate. When the support plate 34 rotates, it can push the plug-in post 36 to move through the curved groove 35. The plug-in post 36 will then drive the locking block 37 to move, so that the locking block 37 is disengaged from the locking groove 32. The plug-in block 31 can then be pulled out from the hollow column 1, and the hook can be removed from the top of the conductive rod 4 for storage. When it is necessary to splice, the plug-in block 31 is inserted into the hollow column 1. The torsion spring 382 will push the support plate 34 to rotate in the opposite direction, so that the locking block 37 is engaged with the locking groove 32, thus locking the plug-in block 31.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
