Description

Technical Field

[0001] This invention relates to the field of operating lever technology, specifically a clampable electrically insulated operating lever. Background Technology

[0002] Electrically insulating operating rods are mainly used for the installation, dismantling, inspection, and maintenance of high-voltage transmission lines, power distribution equipment, and related electrical devices while maintaining a safe distance. The rationality of their structure and the reliability of their operation directly affect the safety factor and work efficiency of live-line work.

[0003] Existing telescopic adjustment mechanisms for clampable power-insulated operating rods mostly employ a single-stage telescopic design with simple threaded tightening or snap-locking. This locking structure is prone to loosening or even failure under vibration, torsion, or large loads during operation, leading to unexpected extension or retraction of the rod. This not only affects the accuracy of operation but may also result in insufficient safe distance between the operator and live parts, potentially causing accidents. Furthermore, existing operating rods often use a fixed rigid connection between the handle and the linkage rod, limiting the maximum telescopic length of the operating rod to the fixed length of the linkage rod, thus preventing a wider range of length adjustments. Some sliding connection transmission structures suffer from slippage, failing to stably transmit clamping force after adjusting the rod length, resulting in uncontrollable clamping action and easy detachment of the clamped electrical components, hindering smooth operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a clampable electrically insulated operating rod to solve the problems mentioned in the background art, such as the accidental extension and retraction of telescopic rods, which not only affect the accuracy of operation but may also result in insufficient safe distance between the operator and live parts, leading to safety accidents; the maximum extension and retraction length of the operating rod is limited by the fixed length of the linkage rod, making it impossible to achieve a wider range of length adjustment; the clamping action is uncontrollable; and the clamped electrical devices are prone to falling off, affecting the smooth progress of the operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clampable power-insulated operating rod, comprising: An insulating operating rod housing has a telescopic rod inserted into its inner cavity, a locking ring installed at the tail end of the insulating operating rod housing, an adjusting rod screwed onto the surface of the locking ring, and a clamp installed at the output end of the adjusting rod via a rotating shaft. A first clamping block is disposed at the top of the insulating operating rod housing. A second clamping block is mounted on the surface of the first clamping block via a rotating shaft. A linkage rod is inserted into the inner cavity of the telescopic rod. An extension rod is inserted into the inner cavity of the linkage rod. The top of the linkage rod is movably connected to one side of the second clamping block. An elastic element is mounted on the other side of the second clamping block. The other end of the elastic element is connected to the surface of the insulating operating rod housing. An installation rod is mounted on the tail end of the telescopic rod. A handle is provided on the surface of the mounting rod. The handle is mounted on the surface of the mounting rod via a rotating shaft. A slide rail is installed on the surface of the handle. A slider is embedded in the inner cavity of the slide rail. A connecting block is installed on the surface of the slider. A fixing plate is installed on the end face of the connecting block. A first positioning hoop is provided on the surface of the fixing plate. A second positioning hoop is provided on the surface of the first positioning hoop. The first positioning hoop and the second positioning hoop are clamped to the outer ring of the linkage rod.

[0006] Preferably, a positioning cylinder is installed on the end face of the linkage rod, the positioning cylinder is in close contact with the surface of the extension rod, and a positioning ring is provided on the surface of the positioning cylinder. The positioning cylinder is used to axially limit the extension rod to prevent axial displacement of the extension rod during operation. The positioning ring is used to fix the positioning cylinder to ensure the connection stability between the positioning cylinder and the linkage rod. At the same time, the positioning ring can be finely adjusted along the axial direction of the positioning cylinder to adapt to the installation requirements of extension rods of different lengths.

[0007] Preferably, the surface of the positioning cylinder is uniformly grooved, the positioning cylinder is inclined, and the surface of the positioning cylinder is threaded. The positioning ring is screwed onto the surface of the positioning cylinder. The grooved design makes the positioning cylinder have a segmented design, and the inclined design leaves a gap between the tail end of the positioning cylinder and the extension rod. The threaded groove and the positioning ring cooperate to achieve tightening and fixing, which can compress the positioning cylinder and thus fix the extension rod, making it convenient to control the extension length of the extension rod under different working conditions.

[0008] Preferably, guide rods are installed at all four corners of the surface of the second positioning hoop. The guide rods pass through the surface of the first positioning hoop and are connected to the fixed plate. The guide rods play a dual role of guiding and limiting, ensuring that the first positioning hoop and the second positioning hoop move along the same axis when clamping or releasing the linkage rod, avoiding uneven clamping force caused by skew. At the same time, the design of the guide rods passing through the fixed plate makes the entire positioning hoop assembly and the handle form a rigid connection, so that no shaking occurs during operation.

[0009] Preferably, a threaded rod is screwed onto the surface of the fixing plate, and the output end of the threaded rod is connected to the surface of the first positioning hoop through a rotating shaft. When the threaded rod rotates, it drives the first positioning hoop to move axially, thereby clamping or releasing the linkage rod. The rotating shaft ensures that the first positioning hoop will not rotate during movement, thus ensuring the consistency of the clamping direction. The entire adjustment process is achieved through threaded transmission, with small operating torque and accurate positioning.

[0010] Preferably, a connector is installed at the top of the linkage rod, and a connecting frame is provided at the top of the connector. A mating joint is installed on the surface of the connecting frame. The connector is connected to the mating joint through a rotating shaft. The rotating shaft connection between the connector and the mating joint allows the second clamping block to have a certain degree of angular freedom during the opening and closing process, which can adapt to clamping objects of different sizes. The connecting frame, as an intermediate transition component, converts the linear motion of the linkage rod into the rotational motion of the second clamping block, realizing the transmission of force and the conversion of motion form.

[0011] Preferably, a guide block is installed on the surface of the connecting frame, and a guide rail is installed on the surface of the second clamping block. The guide block is installed inside the guide rail. The cooperation between the guide block and the guide rail strictly limits the movement trajectory of the second clamping block when it opens and closes, avoiding the clamping block from deviating or jamming during operation. At the same time, the length design of the guide rail determines the maximum opening and closing angle of the second clamping block, which plays a mechanical limiting role and ensures that the clamping force is within a safe range.

[0012] Preferably, a limiting clamp is installed on the inner wall of the locking ring, with the opening of the limiting clamp facing the opening of the clamp. The limiting clamp is used to limit the opening degree of the clamp, preventing the clamp from opening excessively and escaping the control range of the locking ring during operation. The opening orientation design allows the limiting clamp and the clamp to form a clamping fit. When the clamp attempts to expand outward, the inner wall of the limiting clamp generates a reverse restraining force on it, ensuring that the clamp is always in a controllable state.

[0013] Preferably, the operating end of the adjusting rod is equipped with a knob, and the surface of the knob is provided with anti-slip grooves. The knob increases the force application area for the operator and reduces the hand grip required during operation. The anti-slip grooves are used to increase the friction coefficient between the fingers and the knob, so that stable operation can be achieved even when the hands are wet or when wearing insulating gloves. The knob and the adjusting rod are fixedly connected, so there will be no relative slippage when rotating, thus ensuring the adjustment accuracy.

[0014] Preferably, the limiting clamp is of elastic design. The clamp is located inside the locking ring, and the side of the clamp contacts the end face of the insulating operating rod housing. The elastic design ensures that the limiting clamp does not interfere when the clamp is working normally, and only generates elastic resistance when the clamp expands abnormally. This achieves the effect of no interference under normal conditions and automatic limiting under abnormal conditions. The contact surface between the side of the clamp and the end face of the insulating operating rod housing acts as a fulcrum, allowing the adjusting rod to tighten the clamp evenly when tightened, avoiding the problem of uneven clamping caused by unilateral force.

[0015] Compared with the prior art, the present invention provides a clampable power-insulated operating rod, which has the following advantages: This clampable, electrically insulated operating rod allows for flexible adjustment of its overall working length through the insertion and engagement of the insulating operating rod housing and the telescopic rod, adapting to different height requirements for electrical work. The locking ring, adjusting rod, and clamping mechanism reliably lock the telescopic rod, preventing accidental extension or retraction during operation and ensuring operational stability. When the first and second positioning clamps are not clamped to the linkage rod, they move along the surface of the linkage rod with the handle. Pulling out the extension rod increases its length, further expanding the overall extension range of the operating rod. When the first and second positioning clamps are engaged with the surface of the linkage rod, the handle continuously operates the linkage rod. This clamping connection method prevents slippage and loosening of the linkage rod, improving transmission reliability. It allows for stable remote control of clamping actions at any adjusted working length, enabling clamping operations on electrical devices without approaching live parts, effectively improving the safety of live-line work. The elastic element provides continuous preload, causing the second clamping block to automatically close, making the clamping state more stable and preventing accidental detachment of the clamped electrical devices, thus improving reliability during operation.

[0018] This invention provides a technical solution: a clampable power-insulated operating rod. (See also...) Figure 1 It includes an insulating operating rod housing 1, a telescopic rod 2 inserted into the inner cavity of the insulating operating rod housing 1, and a locking ring 3 installed at the tail end of the insulating operating rod housing 1. Please refer to [link / reference]. Figure 4 An adjusting rod 4 is screwed onto the surface of the locking ring 3, and a clamp 5 is installed at the output end of the adjusting rod 4 via a rotating shaft; Please see Figure 1 The first clamping block 6 is located at the top of the insulating operating rod housing 1. A second clamping block 7 is mounted on the surface of the first clamping block 6 via a rotating shaft. (See also...) Figure 2 The inner cavity of the telescopic rod 2 is fitted with a linkage rod 8. Please refer to [link / reference]. Figure 3 An extension rod 18 is inserted into the inner cavity of the linkage rod 8, and the top end of the linkage rod 8 is movably connected to one side of the second clamping block 7. Please refer to [link / reference]. Figure 6 An elastic element 17 is installed on the other side of the second clamping block 7. The other end of the elastic element 17 is connected to the surface of the insulating operating rod housing 1. Please refer to [link / reference]. Figure 1 An installation rod 9 is installed at the tail end of the telescopic rod 2; Please see Figure 5 A handle 10 is disposed on the surface of the mounting rod 9. The handle 10 is mounted on the surface of the mounting rod 9 via a rotating shaft. A slide rail 11 is mounted on the surface of the handle 10. A slider 13 is embedded in the inner cavity of the slide rail 11. A connecting block 12 is mounted on the surface of the slider 13. A fixing plate 14 is mounted on the end face of the connecting block 12. A first positioning clamp 15 is provided on the surface of the fixing plate 14. A second positioning clamp 16 is provided on the surface of the first positioning clamp 15. The first positioning clamp 15 and the second positioning clamp 16 are clamped to the outer ring of the linkage rod 8.

[0019] The insulating operating rod housing 1, telescopic rod 2, linkage rod 8, extension rod 18 and mounting rod 9 are all made of epoxy resin glass fiber reinforced composite material, which has excellent electrical insulation performance, high mechanical strength and weather resistance; The overall working length of the operating rod can be flexibly adjusted by inserting the insulating operating rod housing 1 into the telescopic rod 2, adapting to the power operation needs at different heights. The locking ring 3, adjusting rod 4, and clamp 5 work together to reliably lock the telescopic rod 2, preventing accidental extension or retraction during operation and ensuring operational stability. When the first positioning clamp 15 and the second positioning clamp 16 are not clamped to the linkage rod 8, they can move along the surface of the linkage rod 8 with the handle 10. Pulling out the extension rod 18 increases the length of the linkage rod 8, further expanding the overall extension range of the operating rod. When the first positioning clamp 15 and the second positioning clamp 16 are engaged with the surface of the linkage rod 8, the handle 10 can continuously operate the linkage rod 8, and its clamping... The connection method avoids slippage and loosening of the linkage rod 8, improving transmission reliability. It enables stable remote control of the clamping action at any adjusted working length, allowing clamping of electrical devices without approaching the live conductor, effectively improving the safety of live-line work. At the same time, the transmission cooperation between the slide rail 11 and the slider 13 smoothly converts the rotational motion of the handle 10 into the linear motion of the linkage rod 8, ensuring the accuracy and continuity of the clamping action. By setting an elastic element 17 between the second clamping block 7 and the insulating operating rod housing 1, a continuous preload can be provided to drive the second clamping block 7 to close automatically, making the clamping state more stable, preventing the clamped electrical devices from accidentally falling off, and improving the reliability during operation.

[0020] Please see Figure 3 and Figure 7 A positioning cylinder 19 is installed on the end face of the linkage rod 8. The positioning cylinder 19 is in close contact with the surface of the extension rod 18. A positioning ring 20 is provided on the surface of the positioning cylinder 19. The positioning cylinder 19 is used to axially limit the extension rod 18 to prevent the extension rod 18 from axially displacing during operation. The positioning ring 20 is used to fix the positioning cylinder 19 to ensure the connection stability between the positioning cylinder 19 and the linkage rod 8. At the same time, the positioning ring 20 can be finely adjusted along the axial direction of the positioning cylinder 19 to adapt to the installation requirements of extension rods 18 of different lengths.

[0021] The surface of the positioning cylinder 19 is uniformly grooved. The positioning cylinder 19 is inclined and has a threaded groove. The positioning ring 20 is screwed onto the surface of the positioning cylinder 19. The grooved design makes the positioning cylinder 19 have a segmented design. The inclined design leaves a gap between the tail end of the positioning cylinder 19 and the extension rod 18. The threaded groove and the positioning ring 20 cooperate to tighten and fix the positioning cylinder 19, thereby squeezing the extension rod 18 and fixing it. This makes it convenient to control the extension length of the extension rod 18 under different working conditions.

[0022] Please see Figure 5Guide rods 21 are installed at all four corners of the surface of the second positioning hoop 16. The guide rods 21 all pass through the surface of the first positioning hoop 15 and the fixed plate 14 and are connected. The guide rods 21 play a dual role of guiding and limiting, ensuring that the first positioning hoop 15 and the second positioning hoop 16 move along the same axis when clamping or releasing the linkage rod 8, avoiding uneven clamping force caused by skew. At the same time, the design of the guide rods 21 passing through the fixed plate 14 makes the entire positioning hoop assembly and the handle 10 form a rigid connection, so that there will be no shaking during operation.

[0023] A threaded rod 22 is screwed onto the surface of the fixed plate 14. The output end of the threaded rod 22 is connected to the surface of the first positioning hoop 15 through a rotating shaft. When the threaded rod 22 rotates, it drives the first positioning hoop 15 to move axially, thereby clamping or releasing the linkage rod 8. The rotating shaft ensures that the first positioning hoop 15 will not rotate during movement, thus ensuring the consistency of the clamping direction. The entire adjustment process is achieved through threaded transmission, with small operating torque and accurate positioning.

[0024] Please see Figure 6 A connector 23 is installed at the top of the linkage rod 8, and a connecting frame 24 is provided at the top of the connector 23. A mating head 25 is installed on the surface of the connecting frame 24. The connector 23 is connected to the mating head 25 through a rotating shaft. The rotating shaft connection between the connector 23 and the mating head 25 allows the second clamping block 7 to have a certain degree of angular freedom during the opening and closing process, which can adapt to clamping objects of different sizes. The connecting frame 24 serves as an intermediate transition component, converting the linear motion of the linkage rod 8 into the rotational motion of the second clamping block 7, thus realizing the transmission of force and the conversion of motion form.

[0025] Guide blocks 26 are mounted on the surface of the connecting frame 24, and guide rails 27 are mounted on the surface of the second clamping block 7. The guide blocks 26 are installed inside the guide rails 27. The cooperation between the guide blocks 26 and the guide rails 27 strictly limits the movement trajectory of the second clamping block 7 when it opens and closes, avoiding the clamping block from deviating or jamming during operation. At the same time, the length design of the guide rails 27 determines the maximum opening and closing angle of the second clamping block 7, which plays a mechanical limiting role and ensures that the clamping force is within a safe range.

[0026] Please see Figure 4 A limiting clamp 28 is installed on the inner wall of the locking ring 3. The opening of the limiting clamp 28 faces the opening of the clamp 5. The limiting clamp 28 is used to limit the opening degree of the clamp 5 to prevent the clamp 5 from opening excessively and escaping the control range of the locking ring 3 during operation. The opening orientation design makes the limiting clamp 28 and the clamp 5 form a clamping fit. When the clamp 5 attempts to expand outward, the inner wall of the limiting clamp 28 generates a reverse restraining force on it to ensure that the clamp 5 is always in a controllable state.

[0027] The operating end of the adjusting rod 4 is equipped with a knob 29. The surface of the knob 29 is provided with anti-slip grooves. The knob 29 increases the force application area for the operator and reduces the hand grip required during operation. The anti-slip grooves are used to increase the coefficient of friction between the fingers and the knob 29, so that stable operation can be achieved even when the hands are wet or when wearing insulating gloves. The knob 29 and the adjusting rod 4 are fixedly connected, so there will be no relative slippage when rotating, which ensures the adjustment accuracy.

[0028] The limiting clamp 28 is elastically designed. The clamp 5 is located inside the locking ring 3. The side of the clamp 5 contacts the end face of the insulating operating rod housing 1. The elastic design ensures that the limiting clamp 28 does not interfere with the clamp 5 when it is working normally. It only generates elastic resistance when the clamp 5 expands abnormally, achieving the effect of no interference under normal conditions and automatic limiting under abnormal conditions. The contact surface between the side of the clamp 5 and the end face of the insulating operating rod housing 1 acts as a fulcrum, so that the adjusting rod 4 can tighten the clamp 5 evenly when tightening, avoiding the problem of uneven clamping caused by unilateral force.

[0029] This solution: During operation, first rotate knob 29 to drive adjustment rod 4 to rotate, which in turn drives clamp 5 to tighten or loosen. This, combined with the elastic clamping action of limit clamp 28, locks telescopic rod 2 in the target position within the insulating operating rod housing 1 to determine the working length. Then, rotate threaded rod 22, which, via the rotating shaft, drives first positioning clamp 15 to move axially along guide rod 21, causing first positioning clamp 15 and second positioning clamp 16 to clamp or release linkage rod 8. After clamping, guide rod 21 passes through first positioning clamp 15 and fixed plate 14, ensuring the entire set of positioning clamps moves along the same axis without deviation. Next, rotate handle 10; the cooperation of slide rail 11 and slider 13 converts rotational motion into linear motion, which is transmitted to fixed plate 14 via connecting block 12, pushing linkage rod 8 forward. Linkage rod 8 drives extension rod 18 and the top connector 23 to push forward simultaneously. In the process, the connecting frame 24 converts linear motion into rotational motion and pushes the second clamping block 7 to open around the rotation axis on the first clamping block 6 through the connector 25. During this process, the guide block 26 slides along the guide rail 27 to strictly limit the movement trajectory and maximum opening angle of the second clamping block 7. After clamping in place, the elastic element 17 continuously provides pre-tightening force to drive the second clamping block 7 to automatically close and hold the power device. If it is necessary to further extend the transmission range, the extension rod 18 is pulled out and the positioning ring 20 is tightened. The split structure of the positioning cylinder 19 is squeezed and tightened by the threaded groove to form an axial limit on the extension rod 18. When releasing, the threaded rod 22 is operated in the opposite direction to loosen the positioning clamp. The linkage rod 8 is reset under the restoring force of the elastic element 17 and the rotation of the handle 10. The second clamping block 7 then opens. The entire clamping and releasing process is completed remotely by the handle 10 without having to approach the live part.
