Description
Technical Field
[0001] This utility model relates to the field of power transmission and maintenance technology, and in particular to a clamp-type insulated wire clamp rod to prevent cross-current. Background Technology
[0002] In the current field of power maintenance and emergency repair, live-line working is an important means to ensure the continuity and stability of power supply, and its technological development and application are receiving increasing attention. Live-line working is a common and efficient operating method, especially in the application of live-line connection projects. Through the direct operation of professionals, it is possible to maintain, repair, or handle faults in power lines without affecting the overall operation of the power grid, or to temporarily connect power lines from the grid to meet special power needs. With the increasing frequency of live-line work, the safety risks to workers also increase, which places more stringent requirements on the professional skills, safety protection, and work efficiency of live-line work teams.
[0003] To effectively maintain the stability of the wiring cables and reduce the risk of current ingress during operation, an anti-current-ingress insulated cable clamp rod is now available on the market. The core design feature of this clamp rod is an insulated hook at the top for suspension or positioning, while a cable clamping device is installed below it. This device consists of two semi-circular clamping plates that clamp the cables through mechanical linkage or manual operation, achieving separation and fixation of the two cables. This maintains the necessary safe distance between the two cables during operation, eliminating the need for workers to hold the cables continuously during wiring and ensuring worker safety.
[0004] However, while existing anti-current-entry insulated cable clamps meet the basic requirements of live-line work to a certain extent, they still exhibit certain limitations in practical applications. This is particularly true for cables that are too small or too large; due to the fixed shape of the clamping device, its adaptability is limited, making it difficult to effectively clamp cables of different specifications. Furthermore, when adjusting the distance between two cables, the screws used to adjust the tightness are positioned very close to the cables. This not only increases the difficulty of operation but also introduces potential safety hazards, such as accidental contact or loose screws leading to unstable clamping, further exacerbating the risks of live-line work. Utility Model Content
[0005] To overcome the shortcomings of poor adaptability and inconvenient operation, this utility model provides a clamp-type anti-current insulated wire clamp rod with good adaptability and easy operation.
[0006] A clamp-type anti-current-entry insulating cable clamp includes a handheld rod with a connecting rod connected to its upper end and a hook connected to the top of the connecting rod. An adjustment assembly is provided on the handheld rod, with a clamping clamp connected to its upper end. The adjustment assembly is used to adjust the distance between the clamping clamp and the hook. A mounting bracket is connected to the side of the clamping clamp. An adjustment rod is rotatably connected to the left end of the mounting bracket, and a guide rod is connected to the right end of the mounting bracket. A movable plate is slidably connected to the mounting bracket. The left end of the movable plate is threadedly connected to the adjustment rod, and the right end of the movable plate is slidably connected to the guide rod. A fixing assembly for clamping cables is provided at the bottom of the movable plate.
[0007] As a preferred embodiment of this utility model, the fixing component includes a sleeve rod, the top of which is connected to the bottom of the movable plate, and a contact rod slidably connected to the lower end of the sleeve rod. A buffer spring is provided inside the sleeve rod, with one end of the buffer spring connected to the sleeve rod and the other end connected to the contact rod.
[0008] As a preferred embodiment of this utility model, the adjusting assembly includes an adjusting nut, which is rotatably connected to the hand handle. Annular slide rails are provided on the upper and lower sides of the adjusting nut. A fixing ring is fitted onto the bottom of the connecting rod, and a screw is connected to the bottom of the fixing ring. The screw is rotatably connected to the hand handle and threadedly connected to the adjusting nut. The fixing ring is rotatably connected to the top of the hand handle. A clamping clamp is fitted onto the fixing ring. The outer ring of the adjusting nut has several grooves.
[0009] As a preferred embodiment of this invention, a limiting ring is connected to the connecting rod.
[0010] As a preferred embodiment of this invention, a sponge pad is connected to the bottom of the contact rod.
[0011] As a preferred embodiment of this utility model, a fastening rubber ring is fitted on the sleeve rod, and the clamping clamp is fitted on the fastening rubber ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. Through the threaded connection between the adjusting rod and the moving plate, and the sliding guiding action of the guide rod, combined with the elastic design of the sleeve rod and the buffer spring, flexible clamping and stable fixing of cables of different diameters are achieved, making this device adaptable to various specifications of cables and improving the versatility and flexibility of operation.
[0014] 2. By adjusting the threaded connection between the nut and the screw, and ensuring the stability of the annular slide rail, the distance between the clamping clamp and the hook can be precisely adjusted. This not only facilitates the adaptation to the bending radius of the cable during operation, but also solves the problem of inconvenient spacing adjustment of the original equipment, thus improving work efficiency and safety.

Detailed Implementation
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0021] Example: A clamp-type insulated wire clamp rod to prevent cross-current, such as... Figures 1-4 As shown, the assembly includes a handheld lever 1, a clamping clamp 2, a hook 3, a connecting rod 301, a mounting bracket 4, an adjusting rod 5, a movable plate 6, a guide rod 7, a fixing component 8, and an adjusting component. The upper end of the handheld lever 1 is connected to the connecting rod 301, and the top of the connecting rod 301 is connected to the hook 3. The handheld lever 1 is equipped with an adjusting component, the upper end of which is connected to the clamping clamp 2. The adjusting component is used to adjust the distance between the clamping clamp 2 and the hook 3. The side of the clamping clamp 2 is connected to the mounting bracket 4. The left end of the mounting bracket 4 is rotatably connected to the adjusting rod 5. The bottom of the adjusting rod 5 passes through the mounting bracket 4 and is connected to a swivel handle for easy rotation. The right end of the mounting bracket 4 is connected to the guide rod 7. The movable plate 6 is slidably connected to the mounting bracket 4. The left end of the movable plate 6 is threadedly connected to the adjusting rod 5, and the right end of the movable plate 6 is slidably connected to the guide rod 7. The bottom of the movable plate 6 is equipped with a fixing component 8 for clamping cables.
[0022] like Figure 2 and Figure 3 As shown, the fixing component 8 includes a sleeve rod 81, a buffer spring 82, and a contact rod 83. The top of the sleeve rod 81 is connected to the bottom of the movable plate 6, and the lower end of the sleeve rod 81 is slidably connected to the contact rod 83. The buffer spring 82 is installed inside the sleeve rod 81, with one end connected to the sleeve rod 81 and the other end connected to the contact rod 83.
[0023] like Figure 1 and Figure 4 As shown, the adjustment assembly includes a fixed ring 9, an adjusting nut 10, an annular slide rail 11, and a screw 12. The adjusting nut 10 is rotatably connected to the hand handle 1. The annular slide rail 11 is provided on the upper and lower sides of the adjusting nut 10. The hand handle 1 is provided with a sliding groove. The bottom of the connecting rod 301 is fitted with a fixed ring 9. The bottom of the fixed ring 9 is connected to the screw 12. The screw 12 is rotatably connected to the hand handle 1. The screw 12 is threadedly connected to the adjusting nut 10. The fixed ring 9 is rotatably connected to the top of the hand handle 1. The clamping clamp 2 is fitted on the fixed ring 9. The outer ring of the adjusting nut 10 is provided with several grooves 15.
[0024] When workers perform electrical connection work, to maintain cable stability during the operation, the diameter of the connecting cable is selected according to maintenance or wiring requirements. The cable is then passed through the mounting bracket 4, with one end extending beyond it. The adjusting rod 5 is then turned. As the adjusting rod 5 rotates, the threadedly connected movable plate 6 moves downwards. The movable plate 6 slides on the guide rod 7, and the fixing component 8 presses the cable downwards, thus securing it. Furthermore, the distance between the cable and the hook 3 is adjusted according to the cable's bending radius to ensure smooth cable connection. After adjustment, the worker holds the holding rod 1. After standing at a suitable height, raise the hand lever 1 and hang the hook 3 on the power transmission cable. After the clamped cable is raised, the staff need to take the splicing tools and the end of the cable extending from the mounting bracket 4 to complete the splicing of the two cables. There is no need to hold the splicing cable by hand. Moreover, the fixing component 8 and the mounting bracket 4 hold the cable stably, and the cable remains stable during the splicing process, which is conducive to the safety of the splicing process and solves the instability and danger of the staff holding the cable. Afterwards, maintenance or inspection can be carried out, or even temporary power supply can be used. After use, disconnect the connection of the two cables, and then hold the hand lever 1 to remove the hook 3 from the power transmission cable.
[0025] During the cable fixing process, multiple sleeve rods 81 move downwards with the moving plate 6. After the contact rod 83 contacts the cable downwards, it compresses the buffer spring 82. Meanwhile, the sleeve rods 81 that are not in contact with the cable continue to drive the contact rods 83 downwards. Finally, the top of the cable is squeezed by the contact rods 83, the sides are held by the sleeve rods 81 and the contact rods 83, and the bottom is squeezed by the mounting frame 4, thus completing the cable fixing. This device can clamp and fix cables of different diameters, optimizing the applicability of the device. When the cable fixing is released, the adjusting rod 5 is rotated in the opposite direction, the moving plate 6 moves upwards, the buffer spring 82 rebounds, and the contact rods 83 disengage from the cable, thereby separating from the top and sides of the cable. The cable can then be removed from the mounting frame 4.
[0026] Since the two cables need to be connected, the connecting cables may need to be bent. Thicker cables are more difficult to bend, so the position of the mounting bracket 4 needs to be adjusted downwards. This requires adjusting the position of the clamping clamp 2. At this time, the adjusting nut 10 is rotated. The adjusting nut 10 is threadedly connected to the screw 12. The screw 12 slides up and down in the handle 1, causing the fixing ring 9 to slide on the connecting rod 301. This causes the clamping clamp 2 to move up and down, changing the distance between the mounting bracket 4 and the hook 3. Even during the wiring process, the adjusting nut 10 can be rotated for adjustment to meet the wiring requirements of cables of different diameters. The groove 15 on the adjusting nut 10 provides greater friction, making it easier to rotate the adjusting nut 10. The annular slide rails 11 on the top and bottom sides of the adjusting nut 10 can maintain the stability of the adjusting nut 10 during rotation.
[0027] like Figure 2 As shown, it also includes a limiting ring 13. The connecting rod 301 is connected to the limiting ring 13. The limiting ring 13 is used to limit the adjustment position of the clamping clamp 2 to prevent the mounting bracket 4 from getting too close to the hook 3. The limiting ring 13 ensures a safe distance between the mounting bracket 4 and the hook 3, and prevents the operator from making a mistake when turning the adjusting nut 10, causing the mounting bracket 4 at the top to continue to approach the hook 3.
[0028] like Figure 3 As shown, it also includes a sponge pad 14. The bottom of the contact rod 83 is connected to the sponge pad 14. The sponge pad 14 can prevent the contact rod 83 from squeezing the cable, and the contact between the sponge pad 14 and the cable can generate greater friction, which helps to stabilize the cable.
[0029] like Figure 1 As shown, it also includes a fastening rubber ring 16. The fastening rubber ring 16 is fitted on the sleeve rod 81, and the clamping clamp 2 is fitted on the fastening rubber ring 16. The tightened clamping clamp 2 is connected to the fastening rubber ring 16. The surface of the fastening rubber ring 16 is provided with vertical uneven stripes. During the tightening process of the clamping clamp 2, the fastening rubber ring 16 is squeezed, thereby enhancing the connection stability between the clamping clamp 2 and the sleeve rod 81.
[0030] When performing electrical connection work, the worker first selects the appropriate cable diameter according to the maintenance or wiring requirements and passes it through the mounting bracket 4, leaving an appropriate length. Then, by turning the adjusting rod 5, the threaded connection drives the moving plate 6 to slide downwards on the guide rod 7, causing the sleeve rod 81 and contact rod 83 in the fixing assembly 8 to press the cable downwards. The contact rod 83, while compressing the buffer spring 82, makes close contact with the cable, while the sleeve rod 81, which is not in contact with the cable, continues to drive the contact rod 83 downwards. Finally, the top of the cable is pressed by the contact rod 83, the sides are held abutted by the sleeve rod 81 and contact rod 83, and the bottom is supported by the mounting bracket 4, thus achieving stable clamping and fixing of the cable, accommodating cables of different diameters. Next, according to the required cable bending radius, the position of the clamping clamp 2 on the handrail 1 is adjusted by turning the threaded connection between the adjusting nut 10 and the screw 12. After confirming the position is correct, the distance between the mounting bracket 4 and the hook 3 is adjusted to ensure smooth wiring. The groove 15 on the adjusting nut 10 facilitates rotation, while the annular slide rail 11 ensures stability during adjustment. After adjustment, the hook 3 is hung on the power transmission cable, and the clamped cable is lifted, allowing workers to easily perform wiring operations without holding the cable, thus improving safety and stability. During cable fixing, the elasticity of the buffer spring 82 and the protection of the sponge pad 14 ensure that the cable is not damaged and enhance the stability of the clamping. In addition, the limit ring 13 effectively prevents excessive proximity between the mounting bracket 4 and the hook 3, ensuring operational safety. Finally, after use, the cable fixing can be easily released and the hook 3 removed from the power transmission cable by reversing the adjusting rod 5 and the adjusting nut 10. Throughout the process, the fastening rubber ring 16 ensures the connection stability between the clamping clamp 2 and the sleeve rod 81, improving overall reliability and durability.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
