[0012] Further, the traction mechanism includes a rope protection block II, which includes a bottom plate II, with a shaft hole VIII on the bottom plate II, and a rope protection frame II connected to the edge of the bottom plate II. The rope protection frame II is arc-shaped. The shaft hole VIII is connected to connecting shaft II. Pulley II is connected inside the rope protection frame II.
[0013] Further, it also includes a support column, a grounding wire fixing block, and a fixing block. The support column, the grounding wire fixing block, and the fixing block are all connected between two protection plates. The support column, the grounding wire fixing block, and the fixing block are all connected to the edge of the protection plate. The support column, the grounding wire fixing block, and the fixing block are all connected to the protection plate by screws, and corresponding holes for the bolts to pass through are provided on the protection plate.
[0014] Further, a grounding wire fixing hole is provided on the side surface of the grounding wire fixing block, and the grounding wire fixing hole is a threaded hole.
[0015] Further, the protection plate, the grounding wire fixing block, clamp I, clamp II, pull rod, connecting shaft I, trigger plate, connecting shaft III, and connecting shaft IV are made of stainless steel.
[0016] The two connecting shafts III are respectively the rotation shafts of clamp I and clamp II. The up and down movement of connecting shaft I causes the two pull rods to move with connecting shaft I as the axis. The two pull rods then cause clamp I and clamp II to rotate relative to each other through connecting shaft IV. The settings of gear part I and gear part II make the rotation of clamp I and clamp II synchronous. The setting of the spring enables clamp I and clamp II to achieve automatic closing.
[0017] During actual use, when the trigger plate is pushed upward, clamp I and clamp II open. When the trigger plate is pulled downward, clamp I and clamp II close. The settings of the waist-shaped hole I and connecting shaft II provide limits for the up and down movement of the trigger plate, improving the stability of use.
[0018] The two side rod parts are connected by a trigger handle, and when in use, the two trigger plates can be synchronously operated through the trigger handle.
[0019] The connecting columns on the two pull rods are connected to different left and right positions on the top edge of the lower connecting seat, so that the two pull rods interfere with each other.
[0020] The setting of the safety mechanism improves the practical convenience. When the trigger plate is pushed upward to open the clamp I and the clamp II, the hook part slides along the hypotenuse and enters the locking angle. Due to the setting of the safety spring, the hook part will be clamped in the locking angle to realize the positioning of the trigger plate, so as to ensure that the clamp I and the clamp II are in the open state. When the top end of the lock tongue plate touches the wire, the lock tongue plate is pushed downward by the wire. At this time, the lower end of the long side is connected to the safety buckle. As the long side moves downward, the safety buckle is pushed open, and the hook part disengages from the locking angle to release the limit on the trigger plate. Due to the action of the spring, the clamp I and the clamp II are closed. Repeat the above actions when using again; the setting of the small pillar I provides a guiding function for the up and down movement of the safety buckle to prevent the safety buckle from being misaligned during the up and down movement, and the setting of the torsion spring enables the safety buckle to automatically return when there is no external force to push it down.
[0021] The setting of the traction mechanism enables the opening of the clamp I and the clamp II to be remotely operated by using a traction rope. After the clamp I and the clamp II are closed, by pulling the traction rope, the connecting shaft I can be moved downward, so as to realize the opening of the clamp I and the clamp II. The setting of the rope protection block I and the rope protection block II provides protection for the traction rope to prevent the traction rope from falling off or interfering and winding with other components.
[0022] The support column, the grounding wire fixing block and the fixing block provide support between the two guard plates, so that the space between the two guard plates can be used to install the clamp transmission mechanism and the traction mechanism.
[0023] When the present invention is in use, it is hung on the wire through the clamp I and the clamp II, and the grounding wire is connected to the grounding wire fixing block to realize the hanging of the grounding wire. After the work is completed, the clamp I and the clamp II can be opened through the trigger handle or the traction mechanism to remove the device from the wire.
[0024] A method for using a quick-install grounding wire clamp for a transmission line that is convenient to use includes the following steps:
[0025] S1. Pull down the trigger plate through the trigger handle to open the clamp I and the clamp II, check the safety mechanism to ensure that the hook part is clamped in the locking angle, and keep the clamp I and the clamp II in the open state;
[0026] S2. Connect the grounding wire to the grounding wire fixing block through the grounding wire fixing hole;
[0027] S3. Connect the insulating rope to the traction rope, and hoist the quick-install grounding wire clamp for the transmission line to the cross arm directly above the conductor at the operation point through the insulating rope and pulley, ensuring that the jaws of clamp Ⅰ and clamp Ⅱ face downward towards the conductor;
[0028] S4. Loosen the insulating rope to let the quick-install grounding wire clamp for the transmission line freely fall on the conductor. Due to the action of gravity and impact, the conductor knocks down the tongue plate, and the long side pushes out the safety buckle. Under the action of the spring, clamp Ⅰ and clamp Ⅱ close to complete the clamping of the conductor;
[0029] S5. According to the work requirements, hang the grounding wires on other phases of the power-off maintenance line also according to steps S1 - S4. Both sides of the line should be grounded;
[0030] S6. After the work is completed, pull the insulating rope to open clamp Ⅰ and clamp Ⅱ, so that the quick-install grounding wire clamp for the transmission line falls off the conductor. The maintenance personnel retrieve the quick-install grounding wire clamp for the transmission line and remove the grounding wire.
[0031] The beneficial effects of the present invention are as follows:
[0032] 1. It is provided with a clamp transmission mechanism. Clamp Ⅰ and clamp Ⅱ realize the clamping of the conductor. The setting of the spring enables clamp Ⅰ and clamp Ⅱ to automatically close, and the setting of the trigger plate and trigger handle makes it convenient to open clamp Ⅰ and clamp Ⅱ;
[0033] 2. It is provided with a safety mechanism, which realizes the automatic closing of clamp Ⅰ and clamp Ⅱ and the positioning when clamp Ⅰ and clamp Ⅱ are opened. At the same time, it has the function of repeated operation. No complex operation is required for repeated use, greatly improving the convenience of use;
[0034] 3. The setting of the small support Ⅰ and the waist-shaped hole Ⅱ provides a limit for the movement of the tongue plate, preventing the tongue plate from being misaligned and improving the stability of equipment use;
[0035] 4. The setting of the torsion spring enables the tongue plate to automatically return to its position, improving the convenience of equipment use;
[0036] 5. The setting of the traction mechanism enables clamp Ⅰ and clamp Ⅱ to be remotely opened through the traction rope, further improving the convenience of use;
[0037] 6. The present invention has strong applicability, is convenient and rapid, and meets the requirements of the maximum grounding short-circuit current capacity. Description of the Drawings

[0063] Further, it further includes a support column 2, a grounding wire fixing block 3 and a fixing block 4. The support column 2, the grounding wire fixing block 3 and the fixing block 4 are all connected between two protective plates 1. The support column 2, the grounding wire fixing block 3 and the fixing block 4 are all connected to the edge of the protective plate 1. The support column 2, the grounding wire fixing block 3 and the fixing block 4 are all connected to the protective plate 1 by screws. Corresponding holes for the bolts to pass through are provided on the protective plate 1.
[0064] Further, a grounding wire fixing hole 301 is provided on the side of the grounding wire fixing block 3. The grounding wire fixing hole 301 is a threaded hole.
[0065] Further, the protective plate 1, the grounding wire fixing block 3, the first clamp 6, the second clamp 7, the pull rod 9, the first connecting shaft 10, the trigger plate 13, the third connecting shaft 19 and the fourth connecting shaft 20 are made of stainless steel.
[0066] The two third connecting shafts 19 are respectively the rotation shafts of the first clamp 6 and the second clamp 7. The up and down movement of the first connecting shaft 10 causes the two pull rods 9 to move with the first connecting shaft 10 as the axis. The two pull rods 9 in turn cause the first clamp 6 and the second clamp 7 to rotate relative to each other through the fourth connecting shaft 20. The settings of the first gear part 603 and the second gear part 703 make the rotation of the first clamp 6 and the second clamp 7 synchronous. The setting of the spring 8 enables the first clamp 6 and the second clamp 7 to achieve automatic closing.
[0067] During actual use, when the trigger plate 13 is pushed upward, the first clamp 6 and the second clamp 7 open. When the trigger plate 13 is pulled downward, the first clamp 6 and the second clamp 7 close. The settings of the first waist-shaped hole 1304 and the second connecting shaft 15 provide limits for the up and down movement of the trigger plate 13, improving the use stability.
[0068] The two side rod parts 1302 are connected by a trigger handle 14. During use, the two trigger plates 13 can be synchronously operated through the trigger handle 14.
[0069] The connecting columns 901 on the two pull rods 9 are connected to the left and right positions on the top edge of the lower connecting seat 902 with different positions, so that the two pull rods 9 do not interfere with each other.
[0070] The setting of the insurance mechanism 21 improves the practical convenience. When the trigger plate 13 is pushed upward to open the clamp I 6 and the clamp II 7, the hook part 2401 slides along the hypotenuse 1307 and enters the locking angle 1308. Due to the setting of the insurance spring 26, the hook part 2401 will be clamped within the locking angle 1308 to position the trigger plate 13, thus ensuring that the clamp I 6 and the clamp II 7 are in the open state. When the top end of the locking tongue plate 22 touches the wire, the locking tongue plate 22 is pushed downward by the wire. At this time, the lower end of the long side 2201 is connected to the insurance buckle 24. As the long side 2201 moves downward, the insurance buckle 24 is pushed open, and the hook part 2401 disengages from the locking angle 1308 to release the limit on the trigger plate 13. Due to the action of the spring 8, the clamp I 6 and the clamp II 7 close. When using it again, just repeat the above actions; the setting of the small support pillar I 101 provides a guiding function for the up and down movement of the insurance buckle 24 to prevent the insurance buckle 24 from being misaligned during the up and down movement, and the setting of the torsion spring 27 enables the insurance buckle 24 to automatically return when there is no external force to push it down.
[0071] The setting of the traction mechanism enables the opening of the clamp I 6 and the clamp II 7 to be remotely operated using a traction rope. After the clamp I 6 and the clamp II 7 are closed, by pulling the traction rope, the connecting shaft I 10 can be moved downward, thereby realizing the opening of the clamp I 6 and the clamp II 7. The setting of the rope protection block I 12 and the rope protection block II 17 provides protection for the traction rope to prevent the traction rope from falling off or interfering and winding with other components.
[0072] The support column 2, the grounding wire fixing block 3, and the fixing block 4 provide support between the two guard plates 1, so that the space between the two guard plates 1 can be used to install the clamp transmission mechanism 5 and the traction mechanism.
[0073] When the present invention is in use, it is suspended on the wire through the clamp I 6 and the clamp II 7, and the grounding wire is connected to the grounding wire fixing block 3 to realize the hanging of the grounding wire. After the work is completed, the clamp I 6 or the clamp II 7 can be opened through the trigger handle 14 and the traction mechanism to remove the device from the wire.
[0074] A method for using a convenient-to-use quick-install grounding wire clamp for transmission lines includes the following steps:
[0075] S1. Pull down the trigger plate 13 through the trigger handle 14 to open the clamp I 6 and the clamp II 7, check the insurance mechanism 21 to ensure that the hook part 2401 is clamped within the locking angle 1308, and keep the clamp I 6 and the clamp II 7 in the open-mouth state;
[0076] S2. Connect the grounding wire to the grounding wire fixing block 3 through the grounding wire fixing hole 301;
[0077] S3. Connect the insulating rope to the towing rope, and hoist the quick-install grounding wire clamp for the transmission line to the cross arm directly above the working point conductor through the insulating rope and pulley, ensuring that the jaws of clamp Ⅰ6 and clamp Ⅱ7 face downward towards the conductor;
[0078] S4. Loosen the insulating rope to allow the quick-install grounding wire clamp for the transmission line to freely fall onto the conductor. Due to the action of gravity and impact, the conductor will knock down the locking tongue plate 22, and the long side 2201 will push out the safety buckle 24. Under the action of the spring 8, clamp Ⅰ6 and clamp Ⅱ7 will close to complete the clamping of the conductor;
[0079] S5. According to the work requirements, hang the grounding wires on other phases of the power outage maintenance line also according to steps S1 - S4. Both sides of the line should be grounded;
[0080] S6. After the work is completed, pull the insulating rope to open clamp Ⅰ6 and clamp Ⅱ7, so that the quick-install grounding wire clamp for the transmission line falls off the conductor. The maintenance personnel retrieve the quick-install grounding wire clamp for the transmission line and remove the grounding wire.
