Description

Technical Field

[0001] This invention belongs to the technical field of cable clamping tools, and relates to an impact-triggered self-locking grounding clamp device, as well as an operation method of the impact-triggered self-locking grounding clamp device. Background Technology

[0002] In the maintenance of high-voltage transmission lines, installing reliable temporary grounding wires at both ends of the work section is a crucial safety measure to ensure that workers are protected from sudden power surges, induced voltages, or residual charges. Currently, most grounding operations use hook-type insulated operating rods, but this method is highly susceptible to adverse weather conditions and complex terrain. Therefore, auxiliary hooking tools or semi-automatic devices have emerged, and the corresponding grounding clamps have evolved from hook-type structures to automatically triggered duckbill-type structures. However, this duckbill-type structure still has certain drawbacks: the triggering or unlocking mechanism is too simple and lacks an effective anti-accidental contact protection structure. During tool transportation, transfer, or installation, accidental collisions or vibrations can easily trigger the unlocking, causing the grounding clamp to open or detach unexpectedly. This can not only damage equipment but also potentially render the safety protection function useless before installation, posing a serious safety hazard. Summary of the Invention

[0003] The present invention aims to provide an impact-triggered self-locking grounding clamp device to prevent accidental triggering and improve operational safety.

[0004] The present invention also provides an operation method for an impact-triggered self-locking grounding clamp device to improve operational safety.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An impact-triggered self-locking grounding clamp device includes a housing, a clamping mechanism, a release mechanism, an interlocking mechanism, an insulating rope connecting ring, a grounding mechanism, and a guide plate; The clamping mechanism includes: a trigger rod, rotatably mounted on the housing via a first rotating shaft, the trigger rod having a slot; a first torsion spring, sleeved on the first rotating shaft, causing the trigger rod to have a clockwise rotation tendency; a clamping block, rotatably mounted on the housing via a second rotating shaft, the clamping block having a locking pin fixed thereon; a torsion spring release block, sleeved on the second rotating shaft, the torsion spring release block having a limiting groove; and a second torsion spring, sleeved on the second rotating shaft, with two torsion arms respectively fixed on the clamping block and the torsion spring release block, causing the clamping block to have a counterclockwise rotation tendency and the torsion spring release block to have a clockwise rotation tendency. In the initial state, the locking pin on the clamping block is locked in the slot of the trigger rod, and the clamping block is in the open state. When the wire hits and pushes the trigger rod to rotate, the locking pin disengages from the slot, and the clamping block rotates counterclockwise under the action of the second torsion spring to clamp the wire. The release mechanism includes: a slide rod, which is vertically slidably mounted on the housing and has one end fixedly connected to an insulating rope connecting ring; and a release claw, which is rotatably mounted on the housing and hinged to the other end of the slide rod, with a roller rotatably mounted on the release claw. After the clamping block clamps the wire, the roller of the release claw engages in the limiting groove of the torsion spring release block. Pulling the insulating rope connecting ring causes the release claw, which is hinged to the slide rod, to rotate. The roller disengages from the limiting groove of the torsion spring release block, thereby releasing the second torsion spring and causing the clamping block to loosen the wire. The interlocking mechanism includes an interlocking pin fixed to the clamping block. In the initial state, the interlocking pin prevents the release pawl from rotating counterclockwise. After the clamping block clamps the wire, the interlocking pin moves to a position away from the release pawl, releasing the obstruction to the release pawl.

[0006] As a limitation of the present invention, the grounding mechanism includes at least one conductor contact copper plate that contacts the conductor, a grounding connection copper plate that is connected to the grounding wire, and a flexible cable connecting the two; the clamping block is made of conductive material or has a copper plate that contacts the conductor on its inner side.

[0007] As a further limitation of the present invention, it also includes an intelligent detection module for electrical connection and a limit switch. The limit switch is linked with a trigger rod or clamping block, or with a copper contact plate of the wire. The intelligent detection module senses the state of the limit switch to determine whether the wire is clamped, and feeds back the status information to the operator through an indicator light, a buzzer or a wireless transmission module.

[0008] As another limitation of the present invention, a spring is sleeved on the slide rod, one end of the spring abuts against the inner wall of the housing, and the other end is fixedly connected to the slide rod.

[0009] As a limitation of the present invention, a tension spring is fixedly provided at one end of the release claw that is hinged to the slide bar, and the other end of the tension spring is fixedly connected to the housing.

[0010] As a third limitation of the present invention, there are two guide plates, which are respectively fixed on both sides of the housing and open in a trumpet shape to guide the wire into and impact the trigger rod.

[0011] As a limitation of the present invention, the position of the housing for clamping the wire is arc-shaped.

[0012] As a fourth limitation of the present invention, the copper contact sheet of the conductor is an inverted V-shape, and two are provided along the extension direction of the conductor.

[0013] An operating method for an impact-triggered self-locking grounding clamp device, comprising the following steps: S1. Lock the clamping block's locking pin in the trigger rod's slot, so that the clamping block is in the open state. The interlocking pin blocks the release pawl. At the same time, lower the slide rod so that the release pawl abuts against the interlocking pin on the clamping block. Then rotate the torsion spring release block counterclockwise so that the roller on the release pawl is locked in the limiting groove of the torsion spring release block to form a limit. Stor the second torsion spring and put the entire device in the initial state. S2. The grounding clamp device is lowered through the insulating rope so that the wire contacts the guide plate, slides into the housing, and then hits the trigger rod. S3. The trigger rod rotates counterclockwise, the locking pin falls out of the trigger rod's slot, releasing the clamping block. The clamping block clamps the wire under the action of the second torsion spring, and at the same time the interlocking pin separates from the release claw. S4. The grounding wire forms an electrical connection with the conductor through the clamping block and the grounding mechanism, and the charge is grounded through the grounding wire; S5. When releasing the grounding clamp device, pull the insulating rope upwards, the release claw rotates counterclockwise, the roller disengages from the limit groove of the torsion spring release block, the torsion spring release block rotates clockwise under the action of the second torsion spring, the second torsion spring releases energy after resetting, and the clamping block releases the wire. S6. Retrieve the grounding clamp device via an insulating rope.

[0014] By adopting the above-described technical solution, the beneficial effects achieved by this invention compared to the prior art are as follows: (1) The present invention is provided with an interlocking structure. In the initial state, the interlocking pin and the release claw abut against each other to form a physical block, so that the release claw cannot rotate counterclockwise. This causes the torsion spring release block and the release claw to engage with each other, ensuring that the clamping block is in the open state. This prevents the device from being released from the interlocking state when the trigger rod is not struck by a wire. Even when there is vibration or the insulating rope ring is accidentally pulled, the release mechanism cannot be activated. At the same time, the trigger rod is protected inside the housing and is not easily touched by accident. Therefore, the safety hazards caused by accidental unlocking during transportation or preparation are fundamentally eliminated, and the safety of use is improved. (2) The present invention ensures good electrical connection. The clamping block itself is made of a material with good conductivity. A low-resistance grounding path is formed by grounding connection copper sheet and wire contact copper sheet, and the conductivity is good. (3) The limit switch of the present invention can be linked with the wire, clamping block or trigger rod. The intelligent detection module judges whether the device is in a reliable clamping state through the signal of the limit switch and provides visual information feedback to the operator to realize remote monitoring of the operation status and improve intelligence. (4) The entire device of the present invention is based on a mechanical structure and relies on the basic principles of torsion spring energy storage and release, lever rotation, etc. to realize its functions. It has few parts, a compact and robust structure, and is easy to operate in complex outdoor environments. It is highly practical.

[0015] In summary, this invention integrates the advantages of automatic triggering, mechanical interlocking to prevent accidental contact, and simple and reliable structure, significantly improving the safety of high-voltage transmission line maintenance operations. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and understanding purposes only and are not intended to limit the scope of the invention. Example 1

[0020] like Figure 1As shown, this embodiment includes a housing 1. An insulating rope connecting ring 2 is provided on the top of the housing 1 for connecting and pulling the insulating operating rope. Guide plates 3, flared in shape, are symmetrically fixed to both sides of the bottom of the housing 1 to guide the wire 25 to slide smoothly in. A grounding wire connection port is provided on the side of the housing 1. The core functional components of this embodiment are all integrated inside the housing 1, mainly including a clamping mechanism, a release mechanism, an interlocking mechanism, and a grounding mechanism.

[0021] The housing 1 has an inverted V-shaped structure, including a top plate, front and rear support plates, a side plate fixed on one side, and an opening at the bottom, where a guide plate 3 is installed. The front and rear support plates have arc-shaped through holes for the passage of the conductor 25. The clamping mechanism, release mechanism, interlocking mechanism, and grounding mechanism are all located in the space between the two support plates.

[0022] I. Clamping Mechanism The clamping mechanism is the key to achieving automatic clamping, such as Figure 2 As shown, it includes: Trigger rod 4: Trigger rod 4 is rotatably mounted inside housing 1 via first pivot 5. Specifically, as shown... Figure 3 As shown, a trigger rod mounting base is fixed on the side of the housing 1 without a side plate. A first rotating shaft 5 is fixed to the trigger rod mounting base, and a trigger rod 4 is rotatably mounted on the first rotating shaft 5. One end of the trigger rod 4 extends to the position of an arc-shaped through hole on the housing 1, serving as the force-bearing end for trigger clamping. Figure 4 As shown, the trigger rod has a slot 6.

[0023] First torsion spring 7: It is sleeved on the first rotating shaft 5, with one end fixed to the housing 1 and the other end acting on the trigger rod 4, so that the trigger rod 4 has a tendency to rotate clockwise around the first rotating shaft 5 (taking the direction shown in the figure as an example, the same below), that is, ensuring that the force-bearing end of the trigger rod 4 extends downward, so that the wire 25 pushes the trigger rod 4 upward.

[0024] Clamping block 8: is a V-shaped component, such as... Figure 5 As shown, the device includes a snap-fit ​​arm and a clamping arm, the connection between which is rotatably mounted on the housing 1 via a second rotating shaft 9. The two ends of the second rotating shaft 9 are respectively fixed to the front and rear support plates of the housing 1, and the bent portion of the clamping block 8 is rotatably mounted on the second rotating shaft 9. The end of the clamping block 8 used to clamp the wire 25 is an arc-shaped surface that matches the wire 25. A snap-fit ​​pin 10 is fixed on the snap-fit ​​arm of the clamping block 8, which cooperates with the slot 6 of the trigger rod 4 to form a locking structure.

[0025] Torsion spring release block 11: also sleeved on the second rotating shaft 9, as shown Figure 6 As shown, the torsion spring release block 11 has a U-shaped plate structure with a space in the middle for accommodating the clamping block 8. Limiting grooves 12 are provided on both sides of the torsion spring release block 11. The lower end of the limiting groove 12 has an arc-shaped structure.

[0026] The second torsion spring 13 is sleeved on the second rotating shaft 9, and its two torsion arms are fixedly connected to the clamping block 8 and the torsion spring release block 11, respectively. The second torsion spring 13 is pre-tightened, and its force causes the clamping block 8 to tend to rotate counterclockwise around the second rotating shaft 9 (i.e., clamp inward), while simultaneously causing the torsion spring release block 11 to tend to rotate clockwise around the second rotating shaft 9. There are two second torsion springs 13, located on both sides of the clamping block 8.

[0027] like Figure 7 As shown, in the initial state of the device (ready to be attached), the trigger rod 4 is in the locked position under the action of the first torsion spring 7, and the locking pin 10 on the clamping block 8 is firmly locked into the locking groove 6 of the trigger rod 4. This locking structure overcomes the clamping torque of the second torsion spring 13 acting on the clamping block 8 to rotate counterclockwise, forcing the clamping block 8 to remain in the open state (away from the wire 25), and the entire mechanism is in the energy storage and ready-to-fire state.

[0028] like Figure 8 As shown, when the operator lowers the device via an insulated rope, the wire 25 slides along the guide plate 3 into the housing 1, impacting the force-bearing end of the trigger rod 4. The impact force drives the trigger rod 4 to overcome the force of the first torsion spring 7 and rotate counterclockwise around the first rotating shaft 5. As the trigger rod 4 rotates, its slot 6 quickly disengages from the locking pin 10 of the clamping block 8, releasing the locked clamping block 8. Driven by the elastic potential energy stored in the second torsion spring 13, it immediately rotates rapidly and forcefully counterclockwise around the second rotating shaft 9, firmly clamping the wire 25 onto the arc surface of the clamping block 8, completing the automatic clamping action.

[0029] II. Release Mechanism The release mechanism is used to remotely release the clamping state after maintenance is completed. For example... Figure 8 , Figure 10 As shown, it includes: Slide rod 14: Vertically inserted into the guide hole at the top of housing 1, it can slide up and down. Its upper end is fixedly connected to the insulating rope connecting ring 2. To optimize the operating feel and ensure reset, in this embodiment, a spring 18 is sleeved on slide rod 14. The upper end of spring 18 abuts against the inner wall of housing 1, and the lower end is fixedly connected to slide rod 14. When the insulating rope is released after being pulled, slide rod 14 can automatically return to its original position under the action of spring 18.

[0030] The release claw 16 is rotatably connected to the housing 1 via a pin 15. The release claw 16 is L-shaped. It is rotatably connected to the pin 15 at the bend. There are two release claws 16, which are rotatably mounted on the front and rear support plates of the housing 1, respectively, and cooperate with the two sides of the torsion spring release block 1. The front ends of the two release claws 16 ( Figure 8 Rollers 17 are mounted on the left side of the release claw 16 via small shafts. Figure 8The right side of the slide bar 16 is hinged to the lower end of the slide bar 14 via another pin. In this embodiment, a tension spring 19 may be provided between the release claw 16 and the housing 1, so that the release claw 16 and its roller 17 have a force to keep it falling downward.

[0031] In the initial state, rotating the torsion spring release block 11 causes the roller 17 at the front end of the release claw 16 to engage within the limiting groove 12 of the torsion spring release block 11 (e.g., Figure 9 As shown), a locking structure is formed, which fixes the torsion spring release block 11, thereby preventing the second torsion spring 13 from being released further, so that the clamping block 8 can be maintained in a stable clamping state.

[0032] When the grounding wire needs to be removed, the operator pulls the insulating rope upwards. The insulating rope moves the slide bar 14 upwards, and the slide bar 14 pulls the rear end of the release claw 16 through the hinge point, forcing the release claw 16 to rotate counterclockwise around the pin 15, causing the roller 17 at its front end to lift and disengage from the limiting groove 12 of the torsion spring release block 11. Once the roller 17 disengages, the torsion spring release block 11 is unlocked and then rapidly rotates clockwise under the elastic potential energy of the second torsion spring 13 until the second torsion spring 13 is completely relaxed and its stored energy is completely released. At this time, the clamping block 8 loses the clamping torque from the second torsion spring 13 and can open under the action of gravity or slight shaking, and the device falls off the wire 25, completing the remote release.

[0033] III. Interlocking Mechanism The interlocking mechanism is the core of this device's safety function in preventing accidental release. For example... Figure 5 As shown, it includes two interlocking pins 20, which are vertically fixed to both sides of the clamping block 8. Figure 7 As shown, in the initial state of the device (clamping block 8 open), the interlocking pin 20 is precisely positioned on the swing path of the release claw 16 and abuts against the front end of the release claw 16, forming a solid physical barrier. At this time, regardless of whether the insulating rope is unintentionally pulled due to transportation bumps, accidental contact, or any other reason, attempting to drive the release claw 16 to rotate, the side of the release claw 16 will be rigidly blocked by the interlocking pin 20 and cannot rotate. Therefore, the roller 17 of the release mechanism cannot disengage from the torsion spring release block 11, and the device has no possibility of accidental unlocking. Figure 8 As shown, only when the wire 25 strikes the trigger rod 4 and the clamping block 8 rotates to the clamping position, the interlocking pin 20 fixed to the clamping block 8 also rotates synchronously, completely moving out of the swing area of ​​the release claw 16. At this time, the obstruction to the release claw 16 is released, and the release function enters the enabled state. This achieves an interlocking structure that prevents release if the clamping is not reliable, fundamentally eliminating safety hazards.

[0034] IV. Grounding Structure The grounding system is responsible for establishing a reliable electrical connection path, such as Figure 8As shown, the grounding mechanism includes a conductor contact copper plate 21, a grounding connection copper plate 22, and a flexible cable (not shown in the figure). The conductor contact copper plate 21 consists of two inverted V-shaped copper plates, which are fixed at the arc-shaped through holes of the housing 1 to ensure a large-area, low-resistance good contact with the surface of the conductor 25. The grounding connection copper plate 22 is fixed at the wiring port at the top of the housing 1 and contacts the lug of the grounding wire. The flexible cable connects the two conductor contact copper plates 21 and the grounding connection copper plate 22 to form a low-impedance electrical circuit. The clamping block 8 itself can also be made of a highly conductive aluminum alloy to assist in conductivity, or a copper plate that contacts the conductor 25 can be provided inside the clamping block 8. This embodiment adopts the first method.

[0035] IV. Intelligent Detection Module To further enhance the intelligence and safety of the operation, an intelligent detection module 23 is integrated into the housing 1. This module is electrically connected to a limit switch 24. The trigger of the limit switch 24 is linked to the trigger rod 4 or the clamping block 8, or to the copper contact piece 21 of the wire. This embodiment adopts the third method, linking with the copper contact piece 21 of the wire. Located below the copper contact piece 21 of the wire, when the device reliably clamps the wire 25, the wire 25 abuts against the trigger piece of the limit switch 24, and the state of the limit switch 24 changes. The intelligent detection module 23 receives the signal and can then issue a local prompt through its built-in indicator light and buzzer, or remotely send the clamped status signal to the handheld terminal of the ground monitoring personnel (the method adopted in this embodiment) through a wireless transmission module, realizing real-time monitoring of the operation status. Example 2

[0036] The operation method of the device based on Embodiment 1 includes the following steps: S1. Reliably connect the grounding wire to the grounding connection copper plate 22, and manually open the clamping block 8 so that the locking pin 10 on it is locked in the slot 6 of the trigger rod 4. At this time, the interlocking pin 20 is in the position blocking the release claw 16. Push the slide rod 14 down to the low position so that the side of the release claw 16 abuts against the interlocking pin 20. Then, rotate the torsion spring release block 11 counterclockwise (overcoming the force of the second torsion spring 13) until the roller 17 at the front end of the release claw 16 is engaged in the limiting groove 12 of the torsion spring release block 11. At this time, the second torsion spring 13 is further pre-tightened and stored, and the entire device is in a stable initial ready-to-trigger state.

[0037] S2. Smoothly lower the device to the vicinity of the target wire 25, and use the guide plate 3 to guide the wire 25 to slide into the device and hit the trigger rod 4.

[0038] S3, the trigger lever 4 is struck and rotates counterclockwise, causing the locking pin 10 to disengage from the locking slot 6. Under the strong force of the second torsion spring 13, the clamping block 8 rotates counterclockwise instantly, firmly clamping the wire 25. At the same time, the rotation of the clamping block 8 causes the interlocking pin 20 to move away, releasing the obstruction to the release claw 16.

[0039] S4. The grounding wire forms an electrical connection with the copper contact plate 21 and the conductor 25 through a flexible cable and conductor, and the charge is reliably conducted to the ground. The intelligent detection module issues a clamping indication signal.

[0040] S5. After the maintenance work is completed, pull the insulating rope upward. The pulling force is transmitted through the slide bar 14, causing the release claw 16 to rotate counterclockwise, and the roller 17 to disengage from the limit groove 12. The torsion spring release block 11 then rotates clockwise, the second torsion spring 13 releases energy, and the clamping block 8 loses its clamping force and releases the wire 25.

[0041] S6. After the wire 25 is released, the device is safely brought back to the ground using an insulated rope, completing the entire operation process.

[0042] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
