Description

Technical Field

[0001] This invention relates to the field of live-line working technology, specifically a lightweight live-line working control rod for power distribution networks. Background Technology

[0002] In live-line work on power distribution networks, the insulated operating rod (manipulation rod) is the most essential and commonly used basic tool. Workers use the insulated operating rod to perform operations such as disconnecting leads or pulling switches on energized equipment at ground or intermediate potentials. Its mechanical and insulation properties directly determine the safety and efficiency of the work.

[0003] A search revealed that Chinese Patent Publication No. CN221177107U discloses a novel insulating operating rod for live-line work, comprising a main sleeve rod, an adjusting hole, a secondary support rod, and a fixing hole. The main sleeve rod has an adjusting hole on its outer wall, and a secondary support rod is installed through one end of the main sleeve rod. The secondary support rod has a fixing hole on its outer wall, and a T-shaped fixing pin is installed through the fixing hole. The T-shaped fixing pin has a storage groove inside, and a T-shaped stop is installed through the outer wall of the storage groove. A first spring is installed on the outer wall of the T-shaped stop.

[0004] Current operating levers, such as those described above, are typically independent rod-shaped structures with a total length exceeding three meters. During operation, even slight hand tremors of the operator are amplified by the long lever, causing significant displacement at the operating head. This makes precise alignment between the operating head and the socket difficult during switch-off operations, resulting in inconvenience and room for improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight live-line working lever for power distribution networks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lightweight live-line working lever for power distribution networks, comprising a working part, an insulating part, and a gripping part. The insulating part is located between the working part and the gripping part. A connecting component is fixedly connected between the insulating part and both the working part and the gripping part. A fixing component is fixedly connected to the top of the working part. An attachment component is fixedly connected to the bottom of the gripping part. The attachment component includes a mounting head and an attachment plate. The mounting head is fixedly connected to the bottom outer wall of the gripping part. A guide groove is fixedly connected to the top of one side outer wall of the attachment plate. The mounting head is rotatably connected to a hinge seat 1 via a bearing. The hinge seat 1 is slidably connected inside the guide groove. Several equally spaced hinge seats 2 are fixedly connected to the other side outer wall of the attachment plate. Several equally spaced rollers are rotatably connected inside each of the hinge seats 2. A horizontally arranged handle is fixedly connected to the middle of one side outer wall of the attachment plate. An anti-slip structure is provided at the bottom of one side outer wall of the attachment plate to limit the position of the attachment plate.

[0007] This design allows the operating lever to be attached to the outside of the reinforced concrete pole, making position adjustment more convenient and improving work efficiency. The attachment plate covers the outside of the reinforced concrete pole. Because the hinge seat two fixed inside the attachment plate is rotatably connected to rollers, the vertical position adjustment of the attachment plate can be easily performed. Furthermore, under the action of friction, the attachment plate cannot move radially. Then, pushing the gripping part causes the mounting head at its bottom to rotate inside the hinge seat one, enabling horizontal position adjustment of the working head. When the end of the working head is aligned with the knife switch socket, pushing the hinge seat one allows it to slide inside the guide groove, quickly completing the docking. The position adjustment process has high precision and is less affected by the muscle tremors of the operator.

[0008] As a further preferred embodiment of this technical solution, the anti-slip structure includes a plurality of mounting holes formed on the outer wall of one side of the attachment plate, the plurality of mounting holes being slidably connected to the same anti-slip frame, and two outer strips being fixedly connected to the bottom of the outer wall of one side of the attachment plate, and a slot being formed on the top of the two outer strips and the anti-slip frame, with the same spring being slidably connected to the two slots.

[0009] As a further preferred embodiment of this technical solution, the connecting assembly includes a plug tube coaxially fixed to the bottom outer wall of the working part and adapted to the insulating part. A mounting ring one is fixedly connected to the bottom of the circumferential outer wall of the working part. Two vertically arranged extension strips are fixedly connected to the bottom of the mounting ring one. Two horizontally arranged snap-fit ​​strips are rotatably connected to the bottom of one of the extension strips. A mounting ring two is fixedly connected to the top of the circumferential outer wall of the insulating part. Two clearance grooves adapted to the two snap-fit ​​strips are opened on the circumferential outer wall of the mounting ring two. An annular groove adapted to the snap-fit ​​strips is opened on the bottom of the circumferential outer wall of the mounting ring two. A snap-fit ​​head is fixedly connected to one end of the two snap-fit ​​strips that are close to each other. A limiting sleeve is fixedly connected to the bottom of the other extension strip. A T-shaped hole groove adapted to the snap-fit ​​head is opened inside the limiting sleeve.

[0010] Insert the connector at the bottom of the working part into the socket at the top of the insulating part. Under the restriction of the connector, the working part cannot move horizontally. During this process, the two extension strips on the outside of the mounting ring move downward along the corresponding clearance groove. After the working part and the insulating part are connected, move the two locking strips towards each other. Then, the two will lock into the ring groove, forming a tight fit. Then, insert the locking head at the end of the locking strip into the T-shaped hole groove of the limiting sleeve. The locking head will first shrink and deform and then return to its original shape, so that the locking head is locked into the T-shaped hole groove. Under the restriction of the locking strip, the position of the working part will be firmly fixed and will not move during use.

[0011] As a further preferred embodiment of this technical solution, a rubber sheet is fixedly connected to the top and bottom inner walls of the portion of the T-shaped groove away from the extension strip, and two rubber sheets are fixedly connected to a pressing plate by glue, with the pressing plate facing the two snap-fit ​​parts of the clip heads.

[0012] As a further preferred embodiment of this technical solution, the fixing component includes a mounting arm fixedly connected to the top outer wall of the working part. The top of the mounting arm has a plurality of limiting holes arranged in a ring. The plurality of limiting holes are slidably connected to the same connector. The connector has a locking structure fixedly connected inside to lock the connector to the outside of the mounting arm.

[0013] As a further preferred embodiment of this technical solution, the locking structure includes a threaded sleeve fixedly connected to the middle position of the connector, and the mounting arm has an insertion hole adapted to the threaded sleeve. A bolt is threadedly connected inside the threaded sleeve, and the bolt contacts the mounting arm.

[0014] As a further preferred embodiment of this technical solution, the handle is externally rotatably connected to a grip tube.

[0015] As a further preferred embodiment of this technical solution, the bearing at the connection between the mounting head and the hinge seat is a damping bearing.

[0016] As a further preferred embodiment of this technical solution, the working part, the insulating part, and the gripping part are all made of a combination of epoxy resin and glass fiber, and are all coated with an insulating coating on the outside.

[0017] This invention provides a lightweight live-line working lever for power distribution networks, which has the following advantages:

[0018] (1) By setting up an attachment component, the present invention enables the operating rod to be attached to the outside of the reinforced concrete pole, thereby making the position adjustment process of the operating rod more convenient and improving work efficiency. The attachment plate is covered on the outside of the reinforced concrete pole. Since the hinge seat two fixed on the inner side of the attachment plate is rotatably connected to the roller, the vertical position adjustment of the attachment plate can be easily carried out. Under the action of friction, the attachment plate cannot move radially. Then, push the gripping part to make the mounting head at the bottom rotate inside the hinge seat one, which can realize the horizontal position adjustment of the working head. When the end of the working head is aligned with the knife switch insertion hole, push the hinge seat one to make it slide inside the guide groove, and the docking can be completed quickly. The position adjustment process has high precision and is less affected by the muscle tremors of the workers.

[0019] (2) By setting a connecting component, the bottom of the working part is inserted into the top hole of the insulating part. Under the restriction of the connecting component, the working part cannot move in the horizontal direction. During this time, the two extension strips outside the mounting ring move downward along the corresponding clearance groove. After the working part and the insulating part are docked, the two snap-fit ​​strips are moved towards each other. Then the two will be locked inside the ring groove to form a tight fit. Then the snap-fit ​​head at the end of the snap-fit ​​strip is inserted into the T-shaped hole groove of the limiting sleeve. The snap-fit ​​head will first shrink and deform and then return to its original shape, so that the snap-fit ​​head is locked inside the T-shaped hole groove. Under the restriction of the snap-fit ​​strip, the position of the working part will be firmly fixed and will not move during use. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] This invention provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, the lightweight live-line working lever for power distribution networks includes a working part 1, an insulating part 2, and a gripping part 3. The insulating part 2 is located between the working part 1 and the gripping part 3. A connecting component 5 is fixedly connected between the insulating part 2 and both the working part 1 and the gripping part 3. A fixing component 6 is fixedly connected to the top of the working part 1, and an attachment component 4 is fixedly connected to the bottom of the gripping part 3. The attachment component 4 includes a mounting head 401 and an attachment plate 402. The mounting head 401 is fixedly connected to the bottom outer wall of the gripping part 3, and the top of one side of the outer wall of the attachment plate 402 is fixedly connected to the mounting head 401. The mounting head 401 is rotatably connected to a hinge seat 404 via a bearing, and the hinge seat 404 is slidably connected inside the guide groove 403. Several hinge seats 405 are fixedly connected to the outer wall of the other side of the mounting plate 402. Several rollers 406 are rotatably connected inside each hinge seat 405. A horizontally arranged handle 407 is fixedly connected to the middle of the outer wall of one side of the mounting plate 402. An anti-slip structure is provided at the bottom of the outer wall of one side of the mounting plate 402 to limit the position of the mounting plate 402.

[0028] The anti-slip structure includes several mounting holes on one side of the outer wall of the attachment plate 402. The same anti-slip frame 408 is slidably connected to the mounting holes. Two external strips 409 are fixedly connected to the bottom of one side of the outer wall of the attachment plate 402. A slot is provided on the top of the two external strips 409 and the anti-slip frame 408. The same spring 410 is slidably connected to the two slots. After the height is adjusted, the hand holding the handle 407 is rotated so that the palm part contacts the outer wall of the anti-slip frame 408. Then the elastic stress of the spring 410 is overcome, and the anti-slip frame 408 will be pressed against the outer wall of the reinforced concrete pole. Under the action of friction, the attachment plate 402 can be prevented from moving when adjusting to other directions.

[0029] When performing switch-off work, the attachment plate 402 is placed over the outside of the reinforced concrete pole. Since the hinge seat 405 fixed inside the attachment plate 402 is rotatably connected to the roller 406, the vertical position of the attachment plate 402 can be easily adjusted. Under the action of friction, the attachment plate 402 cannot move radially. Then, the gripping part 3 is pushed so that the mounting head 401 at its bottom rotates inside the hinge seat 404, which can realize the horizontal position adjustment of the working head. When the end of the working head is aligned with the switch insertion hole, the hinge seat 404 is pushed so that it slides inside the guide groove 403, and the docking can be completed quickly. The position adjustment process has high precision and is less affected by the muscle tremors of the workers, which helps to improve work efficiency.

[0030] like Figure 1 and Figure 4As shown, the connecting assembly 5 includes a plug tube 501 coaxially fixed to the bottom outer wall of the working part 1 and adapted to the insulating part 2. A mounting ring 1 502 is fixedly connected to the bottom of the circumferential outer wall of the working part 1. Two vertically arranged extension strips 503 are fixedly connected to the bottom of the mounting ring 1 502. Two horizontally arranged snap-fit ​​strips 504 are rotatably connected to the bottom of one of the extension strips 503. A mounting ring 2 507 is fixedly connected to the top of the circumferential outer wall of the insulating part 2. Two clearance grooves 508 adapted to the two snap-fit ​​strips 504 are opened on the circumferential outer wall of the mounting ring 2 507. An annular groove 509 adapted to the snap-fit ​​strips 504 is opened on the bottom of the circumferential outer wall of the mounting ring 2 507. A snap-fit ​​head 506 is fixedly connected to one end of the two snap-fit ​​strips 504 that are close to each other. A limiting sleeve 505 is fixedly connected to the bottom of the other extension strip 503. A T-shaped hole groove adapted to the snap-fit ​​head 506 is opened inside the limiting sleeve 505.

[0031] A rubber sheet is fixedly connected to the top and bottom inner walls of the T-shaped slot away from the extension strip 503. The two rubber sheets are fixedly connected to a pressing plate 510 by glue. The pressing plate 510 is directly opposite the two clip heads 506 snap-fitting parts.

[0032] Insert the insertion tube 501 at the bottom of the working part 1 into the insertion hole at the top of the insulating part 2. Restricted by the insertion tube 501, the working part 1 cannot move horizontally. Meanwhile, the two extension strips 503 outside the mounting ring 502 move downwards along the corresponding clearance grooves 508. After the working part 1 and the insulating part 2 are properly aligned, move the two locking strips 504 towards each other. They will then lock into the ring groove 509, forming a tight fit. Next, the locking head 506 at the end of the locking strip 504 is inserted into the T-shaped slot of the limiting sleeve 505. 06 will first shrink and deform and then return to its original shape, so that the clip head 506 is locked inside the T-shaped slot. Under the restriction of the snap-fit ​​strip 504, the position of the working part 1 will be firmly fixed and will not move during use. When disassembly is required, pressure is applied to the pressing plate 510, and the snap-fit ​​part of the clip head 506 is compressed under force. When the snap-fit ​​strip 504 can be disengaged from the T-shaped slot, the extension pieces on the outside of the two snap-fit ​​strips 504 are pressed, and the two snap-fit ​​strips 504 will unfold. Then, the working part 1 is pulled upward, thereby completing the disassembly. Disassembly and assembly are convenient and the structure is stable.

[0033] like Figure 1 and Figure 5 As shown, the fixing component 6 includes a mounting arm 601 fixedly connected to the top outer wall of the working part 1. The top of the mounting arm 601 has a plurality of limit holes 602 arranged in a ring. The plurality of limit holes 602 are slidably connected to the same connector 603. The connector 603 has a locking structure fixedly connected inside to lock the connector 603 to the outside of the mounting arm 601.

[0034] The locking structure includes a threaded sleeve 604 fixedly connected to the middle position of the connector 603. The mounting arm 601 has an insertion hole that matches the threaded sleeve 604. A bolt 605 is threadedly connected inside the threaded sleeve 604, and the bolt 605 contacts the mounting arm 601.

[0035] Insert the connector 603 at the bottom of the working head into several limiting holes 602 in the mounting arm 601. Since the limiting holes 602 are arranged in a ring, the limiting holes 602 can still meet the fixing requirements when the connector 603 is rotated to different angles, which is beneficial to improving the adaptability of the operating rod. After the connector 603 is connected, the threaded sleeve 604 in the middle position will also pass through the corresponding through hole of the mounting arm 601. Finally, the bolt 605 is screwed into the threaded sleeve 604 to complete the quick fixing of the connector 603.

[0036] like Figure 3 As shown, a grip tube 411 is rotatably connected to the outside of the handle 407, making it easier for the operator to twist their hand while gripping the outside of the handle 407.

[0037] like Figure 3 As shown, the bearing at the connection between the mounting head 401 and the hinge seat 404 is a damping bearing, which prevents the mounting head 401 and the gripping part 3 from easily deflecting due to slight shaking of the operator's arm, thereby further improving the adjustment accuracy of the operating lever.

[0038] like Figure 1 and Figure 2 As shown, the working part 1, the insulating part 2 and the gripping part 3 are all made of epoxy resin and glass fiber (this is the core insulating material, which is mechanically pultruded, resulting in high strength and low density, making the operating rod lightweight), and all are coated with an insulating coating.

[0039] This invention provides a lightweight live-line working rod for power distribution networks, the specific working principle of which is as follows:

[0040] When using the device, the working part 1, the insulating part 2, and the gripping part 3 are assembled into a whole using the connecting component 5. For example, the connection process between the working part 1 and the insulating part 2 is as follows: the insertion tube 501 at the bottom of the working part 1 is inserted into the insertion hole at the top of the insulating part 2. Under the restriction of the insertion tube 501, the working part 1 cannot move horizontally. During this process, the two extension strips 503 outside the mounting ring 502 move downward along the corresponding relief grooves 508. After the working part 1 and the insulating part 2 are connected, the two locking strips 504 are moved towards each other. Then, the two will be locked inside the ring groove 509, forming a tight fit. Then the locking strips 504... The end clip 506 is inserted into the T-shaped slot of the limiting sleeve 505. The clip 506 will first shrink and deform and then return to its original shape, so that the clip 506 is locked inside the T-shaped slot. Under the restriction of the snap-fit ​​strip 504, the position of the working part 1 will be firmly fixed and will not move during use. When disassembly is required, pressure is applied to the pressing plate 510, and the snap-fit ​​part of the clip 506 is compressed under force. When the snap-fit ​​strip 504 can be disengaged from the T-shaped slot, the extension pieces on the outside of the two snap-fit ​​strips 504 are pressed, and the two snap-fit ​​strips 504 will unfold. Then, the working part 1 is pulled upward, thereby completing the disassembly. The disassembly and assembly are convenient and the structure is stable.

[0041] Then, select a suitable working head according to the work requirements, insert the connector 603 at the bottom of the working head into several limiting holes 602 in the mounting arm 601. Since the limiting holes 602 are distributed in a ring, the limiting holes 602 can still meet the fixing requirements when the connector 603 is rotated to different angles, which is beneficial to improving the adaptability of the operating rod. After the connector 603 is connected, the threaded sleeve 604 in the middle position will also pass through the corresponding through hole of the mounting arm 601. Finally, use the bolt 605 to screw into the threaded sleeve 604 to complete the quick fixing of the connector 603.

[0042] When performing switch-off work, the attachment plate 402 is placed over the outside of the reinforced concrete pole. Since the hinge seat 405 fixed inside the attachment plate 402 is rotatably connected to the roller 406, the vertical position of the attachment plate 402 can be easily adjusted. Under the action of friction, the attachment plate 402 cannot move radially. Then, the gripping part 3 is pushed so that the mounting head 401 at its bottom rotates inside the hinge seat 404, which can realize the horizontal position adjustment of the working head. When the end of the working head is aligned with the switch insertion hole, the hinge seat 404 is pushed so that it slides inside the guide groove 403, and the docking can be completed quickly. The position adjustment process has high precision and is less affected by the muscle tremors of the workers, which helps to improve work efficiency.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
