Description

Technical Field

[0001] This invention relates to the field of line maintenance technology, specifically to a rapid splicing device and method for live-line work on short poles. Background Technology

[0002] During live-line maintenance of distribution networks, when equipment on important lines fails, it is often necessary to disconnect the faulty equipment as soon as possible to avoid causing a larger accident. Operators usually use a bypass method to connect the faulty equipment in parallel before disconnecting it. In production practice, the bypass lines are usually insulated lead-in wires or flexible bypass cables, which are installed using the insulated glove method.

[0003] In practical applications, insulated drain wires and bypass cables typically consist of two copper connectors and a section of flexible cable. During use, two operators hold both ends of the drain wire and place the connecting wire between the stationary and moving modules of the copper connectors. By rotating the rotating body of the drain wire connector, the moving module of the copper connector moves upward along the rotating thread. As the moving module continues to rise, the wire is securely fixed between the stationary and moving modules, thus establishing the bypass.

[0004] Traditional insulated drain wire installation is a near-potential operation, requiring extensive insulation shielding of live parts around the operator. This is difficult and inefficient. During the operation, the operator must hold and rotate the drain wire clamp to secure the wire. If the insulation shielding is not tight enough, it can easily lead to electric shock accidents, posing a high safety risk and failing to meet the actual operational requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid splicing device and method based on short pole live-line work, which solves the technical problem of high safety risks in the installation of existing drain clamps.

Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Example 1 refer to Figure 1 This invention provides a quick-connection device for live-line work using a short pole, comprising a clamp portion 100, an insulating rod portion 200, an anti-detachment hook portion 300, a drive portion 400, and a transmission portion 500. The clamp portion 100 is used to clamp the conductor and connect the lead wire. To ensure reliable connection between the conductor and the clamp portion 100 and for ease of operation, an insulating rod portion 200 with an anti-detachment hook portion 300 is preferably used. The anti-detachment hook portion 300 engages with the clamp portion 100 to lock the clamped conductor. To improve operational efficiency, the drive portion 400 is mounted on the insulating rod portion 200 and drives the anti-detachment hook portion 300 to rotate via the transmission portion 500. Therefore, the anti-detachment hook portion 300 is movably connected to the insulating rod portion 200. Simultaneously, when the drive portion 400 drives the anti-detachment hook portion 300 to clamp the conductor via the transmission portion 500, it locks with the clamp portion 100 to prevent detachment.

[0024] refer to Figure 2 To further explain, the wire clamp 100 includes a fixed wire clamp frame 110, a movable wire clamp 120, a lifting eye screw 130, and a guide anti-detachment rod 150.

[0025] The fixed wire clamp frame 110 has a C-shaped structure. One side of the fixed wire clamp frame 110 has a clamping opening 112 to facilitate the insertion of wires. The other side of the fixed wire clamp frame 110 has a lead wire connecting block 111 for connecting with the lead wire.

[0026] A lifting eye 131 is provided at the bottom of the lifting eye screw 130. The lifting eye 131 is located below the fixed wire clamp frame 110. The top of the lifting eye screw 130 extends through the bottom of the fixed wire clamp frame 110 and into the fixed wire clamp frame 110. The lifting eye screw 130 is threadedly connected to the fixed wire clamp frame 110. At this time, the movable wire clamp 120 is movably connected to the top of the lifting eye screw 130. In use, the wire is placed on the movable wire clamp 120. By rotating the lifting eye screw 130 through the lifting eye 131, the lifting eye screw 130 drives the wire on the movable wire clamp 120 to approach the top of the fixed wire clamp frame 110 and clamp the wire.

[0027] Preferably, the top of the fixed wire clamp frame 110 is provided with an installation groove 113, which is opposite to the movable wire clamp 120. The installation groove 113 is connected to the clamping port 112. At this time, the guide anti-detachment rod 150 is located in the installation groove 113 and is rotatably connected to the fixed wire clamp frame 110. The guide anti-detachment rod 150 has an L-shaped structure. The corner of the guide anti-detachment rod 150 is rotatably connected to the fixed wire clamp frame 110, so that the abutting end 151 of the guide anti-detachment rod 150 cooperates with the installation groove 113, and the sealing end 152 of the guide anti-detachment rod 150 cooperates with the clamping port 112. When clamping the wire, the wire pushes the abutting end 151 upward and deflects upward. At this time, the sealing end 152 deflects and approaches the clamping port 112 to seal the clamping port 112 and prevent the wire from falling off.

[0028] Preferably, in order to facilitate the insertion of the wire and improve the clamping effect on the wire, the guide anti-disengagement rod 150 is rotatably connected to the fixed wire clamp frame 110 through the first torsion spring, so that in the initial state, the blocking end 152 deflects away from the clamping port 112, and the contact end 151 deflects downward and approaches the movable wire clamp 120.

[0029] At this time, the anti-detachment hook 300 and the lifting ring 131 cooperate to clamp the wire by rotating.

[0030] refer to Figure 3 To further explain, the anti-detachment hook part 300 includes an anti-detachment hook 310 and a rotating platform 320. The anti-detachment hook 310 is rotatably connected to the rotating platform 320 around the radial direction of the insulating rod part 200, which facilitates the storage and erection of the anti-detachment hook 310. The rotating platform 320 is rotatably connected to the insulating rod part 200 around the axial direction of the insulating rod part 200, so that the rotation of the rotating platform 320 relative to the insulating rod part 200 drives the lifting eye screw 130 to rotate and clamp the wire. At this time, the drive part 400 is connected to the anti-detachment hook 310 and the rotating platform 320 respectively through the transmission part 500, and is used to drive the anti-detachment hook 310 and the rotating platform 320 to rotate for operation.

[0031] refer to Figure 3 and Figure 4Specifically, the anti-disengagement hook 310 is provided with a horizontal rotating rod 311, which is close to the bottom end of the anti-disengagement hook 310. The rotating table 320 is provided with a support block 330 and a limit block 340.

[0032] Two support blocks 330 are selected, and the two support blocks 330 are set on opposite sides of the anti-disengagement hook 310. The support blocks 330 are vertically embedded in the side wall of the rotating table 320 for easy disassembly and assembly. The horizontal rotating rod 311 is set vertically to the anti-disengagement hook 310, and the ends of the horizontal rotating rod 311 are rotatably connected to the corresponding support blocks 330.

[0033] The support block 330 has a rotating hole 331 and a sliding groove 332. The sliding groove 332 is vertically oriented and located below the rotating hole 331. The sliding groove 332 is connected to the rotating hole 331. Both ends of the horizontal rotating rod 311 are provided with arc-shaped blocks 312, so that the horizontal rotating rod 311 can rotate in the rotating hole 331. At the same time, after rotating a certain angle, the bottom of the anti-detachment hook 310 is pulled down, and the anti-detachment hook 310 can move downward along the sliding groove 332 through the horizontal rotating rod 311. At this time, the horizontal rotating rod 311 is limited by the sliding groove 332 to prevent the anti-detachment hook 310 from rotating, which is convenient for operation. When the anti-detachment hook 310 needs to be stored, the reverse drive can be used, which is simple and convenient to operate. Preferably, when the anti-detachment hook 310 is rotated to the vertical position, it can slide downward until the arc-shaped block 312 contacts the bottom of the sliding groove 332.

[0034] Correspondingly, the limiting block 340 and the anti-disengagement hook 310 are positioned opposite each other. One end of the limiting block 340 is provided with a receiving platform 341, and the other end of the limiting block 340 is provided with a limiting groove 342. The receiving platform 341 is close to the anti-disengagement hook 310, so that when the anti-disengagement hook 310 is flipped from the horizontal state to the vertical state, the hook end of the anti-disengagement hook 310 is located above the receiving platform 341 and opposite to the limiting groove 342. When the anti-disengagement hook 310 moves downward, the anti-disengagement hook 310 cooperates with the limiting groove 342, and the limiting block 340 blocks the opening of the anti-disengagement hook 310. At this time, a lifting ring 131 is fitted between the receiving platform 341 and the anti-disengagement hook 310. During operation, the lifting ring 131 is locked to prevent the lifting ring 131 from falling off.

[0035] Among them, the anti-disengagement hook 310 rotates and slides downwards, driven by the drive unit 400 through the transmission unit 500.

[0036] refer to Figure 5 and Figure 6 To further explain, the transmission unit 500 includes a hinge rod 510, a guide member 511, an L-link 512, a ball head 513, a ball head seat 514, a vertical tie rod 515, and a sliding rotation mechanism.

[0037] The guide member 511 is slidably connected to the inner wall of the rotating table 320 in the vertical direction. One end of the hinge rod 510 is rotatably connected to the bottom end of the anti-disengagement hook 310. The other end of the hinge rod 510 is connected to the ball head 513 through the L-connector 512. The vertical rod of the L-connector 512 is connected to the guide member 511, so that the anti-disengagement hook 310 can rotate synchronously when the rotating table 320 rotates.

[0038] When the L-link 512 moves downward, it drives the guide 511 to move downward. The hinge rod 510 first drives the anti-disengagement hook 310 to rotate around the horizontal rotating rod 311 to a vertical state. Then, it drives the anti-disengagement hook 310 to move downward along the slide groove 332 to cooperate with the limit block 340.

[0039] The ball head 513 mates with the ball head seat 514, with the center of the ball head 513 located on the axis of the rotating table 320. The vertical tie rod 515 connects the ball head seat 514 and the drive unit 400. The drive unit 400 drives the vertical tie rod 515 to move up and down to control the anti-disengagement hook 310 for storage. The vertical tie rod 515 can drive the hinge rod 510 and the guide member 511 to move up and down through the ball head 513 and the ball head seat 514. Since the rotating table 320 needs to rotate during operation, when the vertical tie rod 515 is not coaxial with the rotating table 320, the L-link 512 drives the ball head 513 to rotate around its center on the ball head seat 514, and at the same time can drive the L-link 512 to move up and down, ensuring stable and reliable operation.

[0040] The drive unit 400 drives the rotating table 320 to rotate via a sliding rotation mechanism.

[0041] To further explain, the sliding rotation mechanism includes a gear 520, a vertical rotating rod 521, and a ratchet 522.

[0042] refer to Figure 5 Specifically, a gear ring 523 is provided at the bottom of the inner wall of the rotating platform 320. The gear 520 meshes with the gear ring 523. The vertical rotating rod 521 is connected between the gear 520 and the ratchet 522. The vertical rotating rod 521 is connected to the inner wall of the insulating rod part 200 through the rotating support block 524. The vertical rotating rod 521 is located on one side of the vertical pull rod 515 and is arranged in the same direction as the vertical pull rod 515. The driving unit 400 drives the vertical rotating rod 521 to rotate around its axis, which can drive the rotating platform 320 to rotate on the insulating rod part 200 through the meshing of the gear 520 and the gear ring 523. The wire is clamped by the anti-disengagement hook 310 connected to the lifting ring 131.

[0043] Correspondingly, refer to Figure 1 and Figure 7 The drive unit 400 includes a drive handle 410 and a ratchet drive mechanism 420. The drive handle 410 is sleeved on the outside of the insulating rod 200 and is slidably connected to the insulating rod 200 along its axial direction.

[0044] Among them, reference Figure 6 and Figure 7 The drive handle 410 is connected to the bottom end of the vertical pull rod 515; the ratchet drive mechanism 420 is mounted on the insulating rod 200 and is slidably connected to the insulating rod 200 in the radial direction, and the output end of the ratchet drive mechanism 420 is connected to the ratchet 522 for transmission.

[0045] To further explain, the drive handle 410 includes a sliding sleeve 411, a pressing handle 412, a return spring 413, a pressing member 414, a guide post 415, and a guide sleeve 416.

[0046] Both the guide post 415 and the guide sleeve 416 are located inside the insulating rod portion 200. The bottom end of the guide post 415 is connected to the bottom end of the insulating rod portion 200. The guide sleeve 416 is sleeved on the outside of the top of the guide post 415 and is slidably connected to the guide post 415. The top end of the guide sleeve 416 is connected to the bottom end of the vertical tie rod 515.

[0047] The sliding sleeve 411 is fitted onto the outside of the insulating rod portion 200. A vertical adjustment groove is provided on the insulating rod portion 200. The sliding sleeve 411 is located outside the vertical adjustment groove. One end of the pressing member 414 is connected to the inner wall of the sliding sleeve 411. The other end of the pressing member 414 passes through the vertical adjustment groove and is connected to the bottom end of the vertical pull rod 515 and / or the top end of the guide sleeve 416, so that the downward movement of the sliding sleeve 411 can drive the vertical pull rod 515 and the guide sleeve 416 to move downward through the pressing member 414. Preferably, a stop is provided at the bottom of the vertical pull rod 515, the top end of the guide sleeve 416 is connected to the vertical pull rod 515 through the stop, and the other end of the pressing member 414 is connected to the stop.

[0048] To facilitate the downward sliding of the sliding sleeve 411 and save physical effort, the return spring 413 is sleeved on the outside of the guide sleeve 416. At this time, the return spring 413 is located between the stop block and the bottom of the insulating rod 200. In the initial state, the return spring 413 drives the sliding sleeve 411 to slide downward through the stop block and the pressing part 414. The corresponding anti-disengagement hook 310 flips up and slides down to cooperate with the limit block 340.

[0049] refer to Figure 1 and Figure 8 The top of the pressing handle 412 is rotatably connected to the side wall of the sliding sleeve 411. The sliding sleeve 411 slides downward so that the bottom of the pressing handle 412 contacts the input end of the ratchet drive mechanism 420. This enables the anti-disengagement hook 310 to cooperate with the lifting ring 131, and the ratchet drive mechanism 420 to drive the rotating table 320 through the pressing handle 412.

[0050] Preferred, Reference Figure 8To facilitate storage and prevent the anti-dislodgement hook 310 from flipping over during storage, a locking mechanism 600 is provided on the insulating rod 200. The locking mechanism 600 includes a locking tongue 610, a locking spring 620, and a locking block 630.

[0051] The insulating rod 200 is provided with a vertical locking groove. Taking two locking blocks 630 as an example, the two locking blocks 630 are arranged opposite each other in the radial direction of the insulating rod 200. The back side of the locking block 630 extends into the vertical locking groove, and the front side of the locking block 630 extends through the vertical locking groove to the outside of the insulating rod 200.

[0052] The locking tongue 610 is located below the locking block 630, and the locking spring 620 is located between the two oppositely arranged locking blocks 630. Preferably, the fixed end of the locking spring 620 is connected to the inner wall of the insulating rod portion 200. The locking spring 620 is arranged along the radial direction of the insulating rod portion 200, so that pressing the locking block 630 can drive the locking tongue 610 to move into the vertical locking groove.

[0053] The top of the sliding sleeve 411 is provided with a locking lug 417 that cooperates with the locking tongue 610. When stored, the locking lug 417 is fitted onto the locking tongue 610. When in use, after the anti-detachment hook 310 is connected to the lifting ring 131, the locking block 630 is pressed to disengage the locking tongue 610 from the locking lug 417. At this time, the sliding sleeve 411 automatically moves downward under the drive of the return spring 413, completing the cooperation between the anti-detachment hook 310 and the lifting ring 131.

[0054] Once the operation is complete, slide the sliding sleeve 411 upwards to engage the locking tongue 610 with the locking lug 417. The outer side of the locking tongue 610 is beveled to facilitate the engagement of the sliding sleeve 411.

[0055] Preferably, a second torsion spring is provided on the transverse rotating rod 311, and the second torsion spring is connected to the rotating table 320, so that in the initial state, the anti-disengagement hook 310 remains horizontal under the action of the second torsion spring, and when the sliding sleeve 411 slides down, it tightens the second torsion spring.

[0056] For further explanation, please refer to Figure 1 and Figure 7 The ratchet drive mechanism 420 includes a sliding seat 421, a sliding guide rod 422, a sliding spring 423, a sliding connecting block 424, a ratchet paddle 425, a sliding push rod 426, and a push block 427.

[0057] The sliding seat 421 is located inside the insulating rod part 200 and is connected to the inner wall of the insulating rod part 200 through an auxiliary connecting rod. The sliding seat 421 is horizontally set. Both ends of the sliding guide rod 422 are set on the sliding seat 421 through connecting seats. The sliding spring 423 is sleeved on the outside of the sliding guide rod 422. One end of the sliding connecting block 424 is sleeved on the sliding guide rod 422 and connected to one end of the sliding spring 423. The other end of the sliding spring 423 is connected to the corresponding connecting seat. The other end of the sliding connecting block 424 is connected to the ratchet 522 through the ratchet pawl 425.

[0058] When the sliding connecting block 424 slides on the sliding guide rod 422, the sliding connecting block 424 drives the ratchet 522 to rotate through the ratchet paddle 425, while the sliding spring 423 is compressed. Then, the sliding connecting block 424 slides in the opposite direction under the action of the sliding spring 423, and the ratchet paddle 425 moves to the initial position through the ratchet 522 to wait for the next sliding drive of the ratchet 522. A spring is provided between the ratchet paddle 425 and the sliding connecting block 424.

[0059] For ease of operation, a vertical push groove is provided on the insulating rod 200. One end of the push block 427 is located on the outside of the insulating rod 200, and the other end of the push block 427 passes through the vertical push groove and is connected to one end of the sliding push rod 426. The other end of the sliding push rod 426 is connected to the sliding connecting block 424. The sliding push rod 426 and the sliding seat 421 are arranged in the same direction. Thus, during operation, by repeatedly pushing the push block 427, the sliding connecting block 424 can be moved to slide through the sliding push rod 426.

[0060] Specifically, when the sliding sleeve 411 slides to the bottom of the pressing handle 412 and is opposite to the push block 427, the ratchet 522 is driven by holding the pressing handle 412, which further drives the rotating table 320 to rotate; preferably, a third torsion spring is provided between the top of the pressing handle 412 and the sliding sleeve 411, so that the pressing handle 412 returns to its original position after being pressed, which makes it easy for the operator to hold and operate with one hand, and facilitates operation.

[0061] Preferably, a limiting ring 210 is provided on the insulating rod 200. The limiting ring 210 is located below the vertical push groove. The limiting ring 210 cooperates with the bottom of the sliding sleeve 411, so that the sliding sleeve 411 can slide down until it contacts the limiting ring 210 and then stop. At the same time, the bottom end of the handle 412 is pressed against the push block 427, which further facilitates operation.

[0062] Among them, an anti-slip handle 220 is provided at the bottom of the insulating rod 200. The anti-slip handle 220, the insulating rod 200, the anti-detachment hook 300, the drive part 400 and the transmission part 500 are all made of insulating material, such as epoxy resin material.

[0063] During operation, there is no need for operators to work near the electrical potential, reducing the risk of electric shock. The entire device has no electronic components and can automatically swing and lock the anti-disengagement hook 310. It is also easy for operators to operate with one hand, freeing up the operators' hands and improving the convenience of operation.

The operation drive unit 400 drives the anti-detachment hook part 300 to rotate through the transmission part 500, so that the wire clamp part 100 clamps the wire. The operation drive unit 400 drives the anti-detachment hook part 300 to disengage from the line clamp part 100 via the transmission unit 500.
