Description

Technical Field

[0001] This utility model relates to the field of insulating operating rod technology, and in particular to a modular insulating operating rod for power distribution lines. Background Technology

[0002] Insulated operating rods are indispensable safety tools in power systems, widely used in routine maintenance, repair, and installation of power distribution lines. Operators use these rods to remotely control the switching on and off of power lines, enabling them to perform tasks such as hooking and rigging while maintaining a safe distance from live equipment, thus effectively ensuring their personal safety.

[0003] Traditional insulated operating rods are typically long, straight rods made of insulating material with a fixed length. This makes it difficult for operators to adjust them flexibly according to the actual height of the power distribution line and the working position, causing inconvenience. Furthermore, the insufficient or excessive length of the operating rod forces operators to adopt uncomfortable postures, increasing labor intensity and safety hazards. Long, straight insulated operating rods cannot be angled, making it difficult to adapt to different angle operating needs. Especially when facing complex spatial layouts or power distribution lines with special angles, the flexibility of operation is greatly limited. Utility Model Content

[0037] Reference Figures 1-10 A modular insulating operating rod for power distribution lines, comprising:

[0038] The grip rod 1 has a first connecting hole 12 at its top for handheld operation;

[0039] Connector 2 has first connecting bolts 22 at both ends of the connecting axis that can be threaded into the first connecting hole 12 for expanding the connection;

[0040] Extension rod 3, with second connecting holes 31 at both axial ends, can be threaded to the first connecting bolt 22, and there are multiple second connecting holes 31, which are used to flexibly extend the length of the insulating operating rod 5 according to the actual use environment;

[0041] Angle adjustment component 4 includes a first joint 41 and a second joint 42 that are rotatably hinged to each other. The other end of the first joint 41 is provided with a second connecting bolt 411, and the other end of the second joint 42 is provided with a third connecting bolt 421. Both the second connecting bolt 411 and the third connecting bolt 421 can be threadedly connected to the first connecting hole 12 or the second connecting hole 31.

[0042] The operating lever 5 has an operating head 53 at its top and a third connecting hole 51 at its bottom that is fixedly connected to the operating head 53. The third connecting hole 51 can be threadedly connected to the first connecting bolt 22, the second connecting bolt 411, or the third connecting bolt 421. In use, the second connecting bolt 411 and the third connecting bolt 421 can be connected to the gripping lever 1, the extension rod 3, or the operating lever 5, so that the gripping lever 1, the extension rod 3, the angle adjustment component 4, and the operating lever 5 can be modularly assembled as required.

[0043] In use, the grip rod 1 and the extension rod 3 are connected by the connector 2. Multiple extension rods 3 can be provided as needed. Multiple extension rods 3 are connected to each other by the connector 2. The extension rods 3 and the operating rod 5 are connected by the angle adjustment component 4, so that the angle of the operating rod 5 can be adjusted according to the actual use scenario to extend the overall length and adjust the angle, thereby facilitating operation.

[0044] Furthermore, such as Figure 3 , Figure 5 As shown, a hinge block 414 is provided at one bottom end of the first joint 41, and a through first pin hole 415 is provided on the hinge block 414. A hinge seat 423 is provided at the top end of the second joint 42, and a through second pin hole 425 is provided on the hinge seat 423. The hinge block 414 is rotatably disposed in the hinge seat 423. The first pin hole 415 and the second pin hole 425 are coaxial. A rotating shaft 45 passes between the first pin hole 415 and the second pin hole 425. In use, the first joint 41 and the second joint 42 are hinged together and rotate around the rotating shaft 45, thereby having a pitch angle adjustment function.

[0045] Furthermore, such as Figure 6 , Figure 7 As shown, a first ring body 412 is provided between the hinge block 414 and the second connecting bolt 411. The hinge block 414 and the first ring body 412 are rotatably connected. A rotating shaft passes through the top of the hinge block 414. The rotating shaft passes through the first ring body 412 and is fixedly connected to a limit block 416. In use, the second connecting bolt 411 can drive the first ring body 412 to rotate relative to the hinge block 414 around the axis of the second connecting bolt 411, thereby realizing the adjustment of the horizontal angle.

[0046] like Figure 8As shown, a second ring 422 is provided between the hinge seat 423 and the third connecting bolt 421. The hinge seat 423 and the second ring 422 are fixedly connected to provide stable support.

[0047] Furthermore, such as Figure 3 , Figure 5 , Figure 6 , Figure 9 , Figure 10 As shown, the bottom end face of the first ring body 412 is provided with several actuating teeth 413 surrounding the hinge block 414. Damping adjustment blocks 424 are fixed on the outer walls of both sides of the hinge seat 423. The two damping adjustment blocks 424 are connected to rotatable driven rings 44. Several driven teeth 441 are provided around the outer periphery of the driven ring 44 on the end face of the driven ring 44 near the second ring body 422. The actuating teeth 413 mesh with the driven teeth 441. In use, the first joint 41 rotates around the rotating shaft 45, and the first ring body 412 moves accordingly. The meshing of the actuating teeth 413 with the driven teeth 441 drives the driven teeth 441 to rotate around the damping adjustment block 424, thereby providing a damping effect during the rotation adjustment process and improving the structural strength of the connection between the first joint 41 and the second joint 42, ensuring that the first joint 41 and the second joint 42 can remain in the corresponding position after adjustment; the second connecting bolt When the first ring body 412 rotates around the axis of the second connecting bolt 411 to adjust the horizontal angle, the actuating teeth 413 of the first ring body 412 rotate horizontally and mesh with the driven teeth 441 of the driven rings 44 at both ends, pushing the driven rings 44 at both ends to rotate around their corresponding damping adjustment blocks 424. The driven rings 44 at both ends rotate in opposite directions, so that the driven rings 44 at both ends can be adjusted synchronously and in a coordinated manner when adjusting the horizontal angle. This ensures the overall balance and coordination of the operating lever 5 during the adjustment process, further improves the stability and reliability of the connection structure between the first joint 41 and the second joint 42, makes the connection between the components more robust, and can withstand greater torque and operating load. The horizontal angle adjustment and the pitch angle adjustment do not interfere with each other, so that the operating lever 5 can be adjusted to a wider range of angles, thereby adapting to the operating needs under complex conditions.

[0048] Furthermore, such as Figure 8 , Figure 9 , Figure 10As shown, the damping adjustment block 424 has several recessed slots 426 around its outer periphery. The driven ring 44 has multiple elastic pieces 443 at equal intervals in its inner ring that can elastically abut against the slots 426. The two ends of the inner ring of the elastic pieces 443 have protrusions that can be movably engaged with the slots 426. In use, the first joint 41 rotates around the pivot 45 and drives the driven ring 44 to rotate through the actuating teeth 413, thereby causing the driven ring 44 to drive the elastic pieces 443 to rotate. After the first joint 41 is adjusted to the correct position, the protrusions at both ends of the elastic pieces 443 elastically engage with the slots 426 provided at the corresponding positions of the damping adjustment block 424, thereby forming a limit and maintaining the stable state of the first joint 41 and the second joint 42 after the angle is adjusted.

[0049] Furthermore, such as Figure 9 , Figure 10 As shown, there is a gap between the elastic plate 443 and the inner ring of the driven ring 44, and the elastic plate 443 and the inner ring of the driven ring 44 are connected by a support block 442. The support block 442 is located on the side of the driven ring 44 near the damping adjustment block 424. The inner ring of the other side of the driven ring 44 has an internal thread 444, and a filler ring 43 is connected through the internal thread 444 to fill the gap between the elastic plate 443 and the inner ring of the driven ring 44. This prevents the elastic plate 443 from rotating and generating elastic deformation to disengage from the slot 426, thus fixing the relative connection between the first joint 41 and the second link. The plate 443 cannot rotate, thus preventing the driven ring 44 from rotating. This restricts the rotation of the first ring 412 driven by the second connecting bolt 411, thereby fixing the joint of the angle adjustment component 4. This ensures that the angle adjustment component 4 remains stable after being adjusted to a suitable angle and will not shift due to external force or vibration. The outer ring of the filling ring 43 is connected to the internal thread 444, and the inner ring is rotatably connected to the outer ring of the elastic plate 443. The other end of the filling ring 43 is fixedly connected to a screwing ring 431. In use, by rotating the screwing ring 431, the filling ring 43 is screwed into the gap between the elastic plate 443 and the inner ring of the driven ring 44.

[0050] Furthermore, such as Figure 1 , Figure 2 As shown, a rubber ring 11 is fitted on the outer periphery of one bottom end of the grip rod 1. During use, it is used to increase the friction when the hand grips the rod, and at the same time, it serves as a protective insulation function.

[0051] Furthermore, such as Figure 1 , Figure 2 As shown, the connector 2 also includes a first limiting ring 21. The first connecting bolts 22 are fixed on the two axial ends of the first limiting ring 21 respectively. In use, the first limiting ring 21 is used to connect the two ends of the first connecting bolts 22 and plays a limiting role, restricting the depth of the gripping rod 1, extension rod 3 and operating rod 5 into the first connecting bolts 22.

[0052] Furthermore, such as Figure 1 , Figure 4 As shown, the operating lever 5 also includes a second limiting ring 52, the operating head 53 is fixedly installed on the top of the second limiting ring 52, and the third connecting hole 51 is fixedly installed at the bottom of the second limiting ring 52. In use, the operating lever 5 is used to contact the power distribution line for hooking and retrieval operations, and the second limiting ring 52 is used to connect the operating head 53 and the third connecting hole 51.

[0053] Furthermore, such as Figure 4 As shown, the operating head 53 is a U-shaped rod. One end of the U-shaped rod is fixedly connected to the top wall of the second limiting ring 52, and the other end is bent inward from the opening to form a hook 54, which is used to perform operations such as hanging and hooking the power distribution line.

[0054] Working principle: The operator first selects an appropriate number of extension rods 3 according to the specific location and height of the power distribution line and the operational requirements. Then, the holding rod 1 is connected to multiple extension rods 3 sequentially via the connector 2. To ensure structural stability, the angle adjustment component 4 is preferably connected between the operating rod 5 and the extension rods 3, or between the operating rod 5 and the holding rod 1. When the angle of the operating rod 5 needs to be adjusted to adapt to different operating scenarios, the operator can use the angle adjustment component 4 to achieve horizontal and vertical angle adjustments. After the angle is adjusted to the correct position, the protrusions at both ends of the elastic plate 443 will elastically engage with the slots 426 on the damping adjustment block 424, forming a limit and maintaining a stable state after angle adjustment. To ensure that the angle adjustment has a certain stability... With higher strength and stability, the filling ring 43 can be screwed into the gap between the elastic plate 443 and the inner ring of the driven ring 44 by rotating the screwing ring 431, so that the elastic plate 443 cannot rotate, thereby restricting the rotation of the driven ring 44 and keeping the positions of the first joint 41 and the second joint 42 relatively fixed, ensuring that the operating rod 5 will not be angularly offset due to external force or vibration during use. After the length and angle are adjusted, the operator can use the operating head 53 at the top of the operating rod 5 to perform operations such as hooking and hooking the power distribution line. The operating head 53 is a U-shaped rod with a hook head 54 at the open end of the U-shaped rod, which can effectively grab the component structure on the power distribution line, thereby driving the component to connect or disconnect from the power distribution line.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
