[0002] Due to the increasingly severe contradiction between electricity supply and demand, customers have an increasing demand for electricity and a stronger desire for continuous power supply. As an indispensable part of the power system, disconnectors are generally used at line branches. As electricity supply and demand gradually increase, power equipment is worn out due to continuous use and needs to be replaced. However, some disconnectors are not located on flat terrain. At this time, the insulated boom truck cannot be stably set on the ground for rapid replacement of disconnectors. At the same time, the remaining existing operating equipment cannot operate under power. Therefore, the use of existing demolition equipment has certain limitations.

[0003] After searching, the patent document with announcement number CN206908166U discloses a hydraulic installation device for high-voltage disconnectors. This installation device avoids the large number of personnel and machinery required for the heavy 110kV horizontal opening disconnectors in substations using traditional large-scale lifting equipment; it is suitable for construction in live environments such as expansion, demolition, etc., when large-scale mechanical equipment cannot meet the live safety distance; it improves installation efficiency, reduces construction safety risks and construction costs; it realizes lifting and rotating operations in narrow and complex installation spaces, and performs horizontal position movement, vertical lifting and 360° rotation operations of the entire equipment; it meets the requirements of interlaced installation under the condition that the distance between the switch columns is not fixed; it is small in size, easy to move, runs smoothly, and is safe and reliable.

[0004] However, the above equipment cannot guarantee stable installation on mountain roads and live removal of the isolating switch. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-5 An operating rod for live removal of an isolating switch based on insulating rod technology, comprising a clamping operating rod 1 and a bolt removal operating rod 2, wherein the clamping operating rod 1 comprises a lower insulating tube 3, and a base 4 is arranged on the outer side of the lower insulating tube 3 through a clamp assembly;

[0052] When the clamping operating rod 1 is assembled, the support tube 5 is fixed to the top of the lower insulating tube 3, and then the clamp ring 25 is sleeved on the outside of the support tube 5, so that the base 4 is in contact with the support tube 5, and then the base 4 and the support tube 5 are connected through the first threaded hole 26 and the bolt assembly to connect the clamping operating rod 1;

[0053] A clamping mechanism is provided inside the base 4, and the clamping mechanism includes a fixed block 27 and a movable clamping block 28. A slide groove 29 is provided on the top and side of the base 4. The fixed block 27 is fixed inside the slide groove 29, and the movable clamping block 28 is slidably provided in the slide groove 29. A rotating driving mechanism for driving the movable clamping block 28 to move is provided between the movable clamping block 28 and the lower buckle 7;

[0054] When it is necessary to clamp and install a new device, the new device is placed on the top of the base 4, and then the movable clamping block 28 is driven to move close to the fixed block 27. The new device can be effectively fixed by the stable clamping of the movable clamping block 28 and the fixed block 27. At this time, the contact clamping operating rod can be used to push the new device to the specified installation height, and the new device can be quickly installed.

[0055] A support tube 5 is fixedly provided at the upper end of the lower insulating tube 3, and an upper buckle 6 and a lower buckle 7 are rotatably provided at the upper and lower ends of the support tube 5, respectively. A rotating rod 8 is slidably penetrated inside the lower insulating tube 3, and a connecting female buckle 9 is fixedly provided on the top of the rotating rod 8. The rotating drive mechanism includes an adjusting screw 30, which is rotatably matched with the side of the fixed block 27 and is threadedly penetrated inside the movable clamping block 28. The end of the adjusting screw 30 passes through the base 4 and is fixedly provided with a transmission bevel gear 31. A driving bevel gear 32 is fixedly provided at the bottom of the lower buckle 7, and the driving bevel gear 32 is matched with the transmission bevel gear 31. The longitudinal sections of the fixed block 27, the movable clamping block 28 and the slide groove 29 are all T-shaped.

[0056] In order to stably drive the movable clamping block 27, the operator can hold the lower insulating tube 3 and pull down the rotating rod 8, so that the top of the rotating rod 8 is connected to the female buckle 9 and the lower sub-buckle 7 for plug-in combination, and then rotate the rotating rod 8, so that the rotating rod 8 drives the lower sub-buckle 7 to rotate, and the driving bevel gear 32 starts to rotate;

[0057] Through the cooperation of the driving bevel gear 32 and the transmission bevel gear 31, the adjusting screw 30 begins to be stably supported by the fixed block 28, so that under the sliding limit of the slide groove 29, the movable clamping block 28 moves horizontally to stably clamp and fix the device;

[0058] A first moving groove 10 is provided at the top of the support tube 5, a first slide plate 11 is slidably inserted in the first moving groove 10, a clamping block 12 is fixedly provided at the upper end of the side of the first slide plate 11, a plurality of clamping slots 33 are provided at the bottom of the clamping block 12 close to the base 4, a driving screw 13 is rotatably provided at the top of the upper buckle 6, and the upper end of the driving screw 13 is threadedly inserted into the interior of the first slide plate 11;

[0059] When the old equipment needs to be dismantled, the rotating rod 8 can be pushed up to make the connecting female buckle 9 and the upper sub-buckle 6 be plugged and combined. At this time, the rotating rod 8 is rotated, and the upper sub-buckle 6 drives the driving screw 13 to rotate through the connection between the connecting female buckle 9 and the upper sub-buckle 6. At this time, under the sliding cooperation of the first movable groove 10 and the first slide plate 11, the first slide plate 11 is driven to move longitudinally, and the height position of the clamping block 12 can be adjusted so that the clamping block 12 is located at the top of the equipment to be dismantled, and the multiple clamping slots 33 are matched with the top of the old equipment, so that the old equipment can be stably disassembled, thereby improving the overall operation convenience of the operating rod equipment.

[0060] In order to be able to disassemble the equipment bolts, such as Figure 1 , Figure 3 and Figure 5 As shown, the bolt removal operating rod 2 includes a first side insulating tube 14 and a second side insulating tube 15, a connecting plate 16 is fixedly sleeved between the first side insulating tube 14 and the second side insulating tube 15, a rotating rod 17 is slidably penetrated inside the first side insulating tube 14, a thread is provided on the upper end of the rotating rod 17, and a second slide plate 18 is threadedly sleeved, a limiting tube 19 is fixedly provided on the top of the first side insulating tube 14, a second moving groove 20 is provided on the top of the limiting tube 19, the second slide plate 18 is slidably penetrated in the second moving groove 20, a reflective lens 21 is fixedly provided on the top of the second slide plate 18, the upper end of the rotating rod 17 is threadedly penetrated inside the second slide plate 18, a fixing fixture 22 is fixedly provided on the upper end of the outer wall of the second slide plate 18, two symmetrically arranged second threaded holes 34 are provided on the side of the fixing fixture 22 close to the limiting tube 19, the second threaded hole 34 is connected to the limiting tube 19 by a bolt assembly, and a bolt clamping groove 35 is provided on the end of the fixing fixture 22 away from the limiting tube 19;

[0061] When it is necessary to fix the upper die bolt, the rotating rod 17 can be rotated first, so that the rotating rod 17 rotates and cooperates with the second slide plate 18 thread through its upper end thread. At this time, under the sliding limit of the limiting tube 19 and the second movable groove 20, the second slide plate 18 stably moves longitudinally and drives the reflective lens 21 to move upward. The position of the upper bolt can be determined by the reflective lens 21, and then the position of the upper die nut can be fixed by the bolt clamping groove 35 on the side of the fixing clamp 22. At the same time, the viewing angle of the reflective lens 21 can be adjusted, which is convenient for further effective observation of the upper nut, and further improves the convenience of bolt removal.

[0062] A vertical rod 23 is slidably inserted into the interior of the second side insulating tube 15, and a jacket 24 is fixedly installed on the top of the vertical rod 23. A tightening bolt 36 is threadedly inserted into the side of the jacket 24, and a rotating block 37 is fixedly installed at one end of the tightening bolt 36 away from the jacket 24. A plurality of anti-slip grooves 38 are arranged symmetrically around the outer wall of the rotating block 37.

[0063] After the position of the upper die nut is determined, different types of bolt sleeves can be selected according to the specifications of the bolt, and the bolt sleeves can be inserted into the jacket 24. Then, the rotating block 37 is pushed to rotate and move the tightening bolt 36 horizontally and effectively tighten the bolt sleeve inside the jacket 24 to fix the position of the bolt sleeve. Then, the vertical rod 23 can be driven upward to cooperate with the bolt, and then the vertical rod 23 is rotated to make the bolt sleeve inside the jacket 24 drive the bolt to rotate rapidly, thereby completing the stable removal of the bolt.

[0064] In summary, when using the operating rod for live removal of the isolating switch based on the insulating rod technology, the old equipment needs to be removed first, and the rotating rod 8 can be pushed up to make the connecting female buckle 9 and the upper sub buckle 6 plug and combine. At this time, the rotating rod 8 is rotated, and the upper sub buckle 6 drives the driving screw 13 to rotate through the connection between the connecting female buckle 9 and the upper sub buckle 6;

[0065] At this time, under the sliding cooperation of the first moving groove 10 and the first slide plate 11, the first slide plate 11 is driven to move longitudinally, and the height position of the clamping block 12 can be adjusted so that the clamping block 12 is located at the top of the device to be removed, and the multiple clamping slots 33 are matched with the top of the old device. Then, the first slide plate 11 is rotated clockwise or counterclockwise, so that the old device can be separated from the original installation position and away from the whole live device, so that the old device can be stably disassembled;

[0066] When dismantling the new equipment, the corresponding threads need to be dismantled, and the rotating rod 17 can be rotated first, so that the rotating rod 17 rotates and the threads of the second slide plate 18 are matched through the threads of the upper end thereof. At this time, under the sliding limit of the limiting tube 19 and the second moving groove 20, the second slide plate 18 stably moves longitudinally and drives the reflective lens 21 to move upward. The position of the upper bolt can be determined by the reflective lens 21. At the same time, before the reflective lens 21 is moved upward, the rotation angle of the reflective lens 21 can be adjusted according to the position of the bolt to be removed, so that when the reflective lens 21 moves to the specified position, the nut position of the upper end of the bolt to be removed can be effectively viewed, and then the position of the upper die nut can be fixed by the bolt clamping groove 35 on the side of the fixing clamp 22;

[0067] After the position of the upper die nut is determined, different types of bolt sleeves can be selected according to the specifications of the bolt, and the bolt sleeves can be inserted into the jacket 24, and then the rotating block 37 can be pushed to make the tightening bolt 36 rotate and move laterally and effectively tighten the bolt sleeve inside the jacket 24 to fix the position of the bolt sleeve. Since the tightening bolt 36 can move laterally during continuous rotation, the side wall of the bolt sleeve is squeezed and positioned by the extrusion friction caused by the rotation of the thread, ensuring the stable setting of the bolt sleeve and facilitating the cooperation between the bolt sleeve and the bolt. Then, the vertical rod 23 can be driven to move upward and cooperate with the bolt, and then the bolt sleeve inside the jacket 24 can be driven to rotate rapidly by rotating the vertical rod 23, thereby completing the stable removal of the bolt.

[0068] Finally, the new device is clamped and installed. At this time, the new device is placed on the top of the base 4. Then the operator can hold the lower insulating tube 3 and pull down the rotating rod 8, so that the female buckle 9 connected to the top of the rotating rod 8 is plugged into the lower sub-buckle 7;

[0069] Then, the rotating rod 8 is rotated, so that the rotating rod 8 drives the lower buckle 7 to rotate. At this time, the driving bevel gear 32 starts to rotate, and through the cooperation of the driving bevel gear 32 and the transmission bevel gear 31, the adjusting screw 30 begins to be stably supported under the support of the fixed block 28, so that under the sliding limit of the slide groove 29, the mobile clamping block 28 moves horizontally to stably clamp the equipment and facilitate quick installation.
