Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a live-line connection device and its usage method. Background Technology

[0002] In power distribution network operations, insulating piercing clamps, insulating parallel groove clamps, and insulating grounding clamps are commonly used clamps. Among them, the insulating piercing clamp (or simply piercing clamp) is a common hardware fitting suitable for insulated conductors. It consists of a piercing blade, a torque nut, a fixing screw, and an insulating shell. Electrical connection is achieved by the piercing blade piercing the insulation layer of the conductor, and the torque nut controls the piercing depth. The insulating parallel groove clamp (or simply parallel groove clamp) is used for connecting small-to-medium cross-section aluminum stranded wire or steel-cored aluminum stranded wire, as well as steel stranded wire of overhead lightning protection wires, in positions where they are not under tension. It is also used for jumper connections on non-straight towers. Power engineering materials (fittings) for connecting conductors are mainly used in power line engineering. The insulating grounding clamp (or simply grounding clamp) is a safety tool used for temporarily short-circuiting and grounding de-energized equipment. Its function is to prevent harm to personnel from sudden power restoration and induced voltage from nearby high-voltage equipment during de-energized maintenance or other work, while also discharging residual charge from the de-energized equipment.

[0003] In power distribution network operations, live-line contact devices are used to operate insulating piercing clamps, insulating parallel groove clamps, and insulating grounding clamps, enabling the clamps to clamp the conductors faster and with less effort.

[0004] Current live-line contact devices all use the insulated rod method. As live-line workers use these devices, problems often arise such as difficulty in securing the wires or insecure fixing. Additionally, the openings on both sides of the clamps may shrink during movement, affecting the installation of the main line. Summary of the Invention

[0005] To address the above shortcomings, this invention provides a live-line contact device and its usage method, thereby solving problems such as poor wire fixing and unreliable fixing that often occur with live-line contact devices.

[0010] Furthermore, the fixing plate is U-shaped, and two inclined guide plates are provided at the upper end of the fixing plate, and the two guide plates are arranged in an inverted V-shape.

[0011] Furthermore, a speaker guide platform is provided on one side of the mounting platform, and the middle part of the speaker guide platform corresponds to the middle part of the fixing plate.

[0012] Furthermore, the drive mechanism includes a large motor, a drive disk, a driving gear, a first driven gear, a second driven gear, and a drive mounting housing. The drive disk is rotatably connected inside the drive mounting housing and is connected to the output end of the large motor. The drive disk is provided with a first conical tooth. The driving gear is rotatably connected inside the drive mounting housing via a first rotating rod. The first rotating rod is provided with a second conical tooth, which is parallel to the driving gear. The second conical tooth meshes with the first conical tooth. The first driven gear is rotatably connected inside the drive mounting housing via a second rotating rod.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on this invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Example: Reference Figures 1-2 As shown, a live-line connection device includes a base plate 1, on which two symmetrical fixing blocks 2 are provided. Each fixing block 2 has a fixing plate 3, which is U-shaped. The upper end of each fixing plate 3 has two inclined guide plates 32 arranged in an inverted V-shape to facilitate guiding the main wire into the fixing plate 3, increasing operational accuracy. The base plate 1 has a wire clamp 6 and a driving mechanism 4. The output end of the driving mechanism 4 has two sleeves 40 for driving the wire clamp 6. Each of the two fixing plates 3 has a clamping mechanism 5 for clamping the slave wire. Each of the three fixing blocks 3 is equipped with a clamping rod 31 for fixing the wire clamp 6. Both fixing blocks 2 are equipped with a positioning mechanism 7 for positioning the upper shell 61 and for positioning the wire clamp 6. The base plate 1 is equipped with a toggle mechanism 8. The output end of the toggle mechanism 8 is connected to the input end of the positioning mechanism 7 for unlocking the positioning mechanism 7. Through the above scheme, the wire clamp 6 is fixed to prevent changes in the opening distance of the wire clamp 6 from affecting the installation of the main line. Both sides are equipped with electric slave wire clamping mechanisms 5. The clamping mechanism 5 clamps and releases the slave wire under the control of the motor, so the clamping of the slave wire is more secure, thereby improving the accuracy and efficiency of the live connection.

[0025] Reference Figures 3-4As shown, the clamping mechanism 5 includes a large slider 51, a small slider 52, a small motor 53, a lead screw 54, a first spring 55, and a mounting platform 56. The mounting platform 56 is mounted on the fixed plate 3. A limiting slide rod 561 is provided inside the mounting platform 56. The large slider 51 and the small slider 52 are slidably connected to the limiting slide rod 561 and are located at opposite ends of the mounting platform 56. One end of the lead screw 54 is mounted on the large slider 51 via a bearing. The small slider 52 has a through hole 521, and a nut 522 is provided inside the through hole 521. The other end of the lead screw 54 passes through the through hole 521. The small motor 53 is mounted on the large slider 51 and threadedly connected to the nut 522. A driven tooth 541 is provided on the lead screw 54 near the large slider 51. A reduction gearbox 531 is provided on the output end of the small motor 53, and a driving tooth 532 is provided on the output shaft of the reduction gearbox 531. The driving tooth 532 meshes with the driven tooth 541. One end of the first spring 55 is mounted on the bottom of the mounting platform 56 near the small slider 52, and the other end is mounted on the bottom of the small slider 52. A slot 562 is provided on the mounting platform 56 near the small slider 52. The slot 562 corresponds to the position of the lead screw 54, placing the wire between the small slider 52 and the large slider 51. The small motor 53 drives the driving gear 532 to rotate clockwise via the reduction gearbox 531. The driving gear 532 drives the driven gear 541 to rotate, and the driven gear 541 drives the lead screw 54 to rotate. The small slider 52 moves towards the large slider 51 on the lead screw 54 via the nut 522. During the movement, the elastic force of the first spring 55 gradually increases. The elastic force of the first spring 55 pulls the small slider 52, the large slider 51, the lead screw 54, and the small motor 53 together on the limiting slide bar 561 in a direction away from the large slider 51. When the lead screw 54 is inserted into the slot 562, the small motor 53 continues to rotate until it clamps the slave wire 6. At this time, both the small slider 52 and the large slider 51 are located in the middle of the mounting platform 56. The slave wire clamping can be completed by a single person through electric power, and the operation is simple and convenient. In contrast, the manually operated clamping mechanism 5 is only provided on one side and only clamps the end of the slave wire. The accuracy of the slave wire clamping 6 is relatively low. After the slave wire and the main wire are installed, a little force is required to pull it to make the end of the slave wire detach from the clamping mechanism 5. Compared with manual operation, electric power improves the clamping efficiency and accuracy and makes it easier to release the slave wire.

[0026] Among them, a stop bar is provided on the fixed platform between the small slider 52 and the large slider 51 to prevent the large slider 51 from moving excessively towards the small slider 52, thereby limiting the position of the large slider 51 and ensuring that the position of the wire is in the preset position after the wire is finally clamped.

[0027] The mounting platform 56 is equipped with a photoelectric sensor 563 at its bottom, and the large slider 51 is equipped with a sensing protrusion 511 at its bottom. The position of the sensing protrusion 511 corresponds to the position of the photoelectric sensor 563. When it is necessary to loosen the clamp on the slave wire, the small motor 53 drives the active gear 532 to rotate counterclockwise through the reduction gearbox 531. The active gear 532 drives the driven gear 541 to rotate, and the driven gear 541 drives the lead screw 54 to rotate. The small slider 52 moves away from the large slider 51 on the lead screw 54 through the nut 522. When it moves to the end of the mounting platform 56, the lead screw 54 moves relative to the small slider 52, so that the large slider 51 and the small motor 53 slide together with the lead screw 54 on the limit slide bar 561 away from the small slider 52. When the sensing protrusion 511 at the bottom of the large slider 51 moves to the position of the photoelectric sensor 563, the small motor 53 stops running, completing the loosening of the slave wire.

[0028] The large slider 51 has two large rollers 512 rotatably connected to its upper end, and the two large rollers 512 are arranged side by side vertically. The small slider 52 has two small rollers 523 rotatably connected to its upper end, and the two small rollers 523 are arranged side by side vertically. The middle of the two large rollers 512 and the middle of the two small rollers 523 are located on the same plane. The two small rollers 523 cooperate with the two large rollers 512 to clamp the wire 6, which can be used for different specifications of wires and ensures a tight clamping. The fact that the middle of the two large rollers 512 and the middle of the two small rollers 523 are located on the same plane ensures that both the two large rollers 512 and the two small rollers 523 can abut against the outer surface of the wire, thereby firmly clamping the wire.

[0029] The mounting platform 56 located on one side is provided with a horn guide platform 564. The middle part of the horn guide platform 564 corresponds to the middle part of the fixing plate 3, which can better guide the wire into the space between the large slider 51 and the small slider 52.

[0030] Reference Figure 1 and Figure 5As shown, the drive mechanism 4 includes a large motor 41, a drive disk 42, a driving gear 43, a first driven gear 44, a second driven gear 45, and a drive mounting housing. The drive disk 42 is rotatably connected inside the drive mounting housing and is connected to the output end of the large motor 41. The drive disk 42 is provided with a first conical tooth 421. The driving gear 43 is rotatably connected inside the drive mounting housing via a first rotating rod 431. The first rotating rod 431 is provided with a second conical tooth 432, which is parallel to the driving gear 43. The second conical tooth 432 meshes with the first conical tooth 421. The first driven gear 44 is rotatably connected inside the drive mounting housing via a second rotating rod 441. The second driven tooth 45 is rotatably connected inside the drive mounting housing via the third rotating rod 451. Both the first driven tooth 44 and the second driven tooth 45 are meshed with the driving tooth 43. One end of the second rotating rod 441 and the third rotating rod 451 respectively passes through the drive mounting housing and connects to the sleeve 40. The large motor 41 drives the drive disk 42 to rotate, the drive disk 42 drives the first conical tooth 421 to rotate, the first conical tooth drives the second conical tooth 432 to rotate, thereby driving the first rotating rod 431 to rotate, the first rotating rod 431 drives the driving tooth 43 to rotate, and the driving tooth 43 simultaneously drives the first driven tooth 44 and the second driven tooth 45 to rotate, thereby driving the two sleeves 40 to rotate simultaneously.

[0031] Reference Figures 5-6 As shown, the positioning mechanism 7 includes a locking tongue 71 and a second spring 72. The fixing block 2 has a groove 21 with an opening on one side. The locking tongue 71 is slidably connected within the groove 21. A ramp 711 is provided at the outer end of the locking tongue 71. One end of the second spring 72 is connected to the locking tongue 71 at its inner end within the groove 21, and the other end is connected to the bottom of the groove 21. A long groove 211 is provided on one side of the groove 21, extending through the fixing block 2 to the outside. On one side of the locking tongue 71, there is a protruding rod 712. The protruding rod 712 is slidably connected in the long groove 211. When the locking tongue 71 moves into the groove 21 until it enters the groove 21, it compresses the second spring 72. When the force that drives the locking tongue 71 to move into the groove 21 is released, the locking tongue 71 moves outward by the elastic force of the second spring 72, thus protruding outside the fixing block 2. The protruding rod 712 in the long groove 211 can prevent the locking tongue 71 from falling out of the groove 21.

[0032] Reference Figures 6-7As shown, the actuation mechanism 8 includes a servo motor 81, a connecting arm 82, a connecting rod 83, and an actuating lever 84. A mounting base is provided on the lower side of the base plate 1, and the servo motor 81 is mounted on the mounting base. One end of the connecting arm 82 is connected to the output shaft of the servo motor 81, and the other end is connected to one end of the connecting rod 83. The actuating lever 84 is L-shaped, and its corner is rotatably connected to the fixed block 2 by bolts. The other end of the connecting rod 83 is connected to the actuating lever 84. One end is connected, the protruding rod 712 extends outward, and the other end of the actuating rod 84 is located next to the protruding rod 712 and abuts against the protruding rod 712. The servo motor 81 is activated, and the servo motor 81 drives the connecting arm 82 to rotate around the output shaft of the servo motor 81. The connecting arm 82 drives one end of the actuating rod 84 to move downward through the connecting rod 83, and the other end of the actuating rod 84 moves to the left or right. The actuating rod 84 moves the protruding rod 712 within the long groove 211, causing the locking tongue 71 to retract into the groove 21.

[0033] Among them, the connecting rod 83 is an adjustable telescopic rod. By adjusting the length of the connecting rod 83, the initial position of the actuating rod 84 against the end of the protruding rod 712 can be adjusted, thereby ensuring that the distance of the actuation of the protruding rod 712 reaches the point where the locking tongue 71 retracts into the groove 21.

[0034] Reference Figure 1 , Figure 8 and Figure 9 As shown, the wire clamp 6 includes an upper shell 61, a lower shell 62, and a fixing member 63. The fixing member 63 includes two screws 631 and a clamping plate 632. One end of each screw 631 is provided with a hexagonal screw head 6311. The clamping plate 632 is provided with two screw holes. The other ends of the two screws 631 pass through the upper shell 61 and the lower shell 62 respectively and are threaded into the two screw holes. When the screws 631 rotate, the screws 631 do not move, but the clamping plate 632 moves relative to them. The clamping plate 632 pushes the lower shell 62 closer to the upper shell 61, thereby making the lower shell 62 and the upper shell 61 fit tightly together, clamping the secondary wire and the main wire in between.

[0035] The hexagonal screw head 6311 is fitted with a copper cap 6312. One end of the copper cap 6312 is provided with a hexagonal copper head 6313. The copper cap 6312 is provided with a hexagonal groove in the middle. The hexagonal groove is adapted to the hexagonal screw head 6311. The hexagonal copper head 6313 is fitted into the sleeve 40. By fitting the hexagonal copper head 6313 into the sleeve 40, the sleeve 40 can rotate to drive the hexagonal copper head 6313 to rotate, thereby causing the screw 631 to rotate.

[0036] It should be noted that the connection between the hexagonal copper head 6313 and the copper cap 6312 is hollow. When the force of twisting the hexagonal copper head 6313 reaches a certain level, the connection between the hexagonal copper head 6313 and the copper cap 6312 will break. The hardness of copper is relatively moderate. Before the connection between the hexagonal copper head 6313 and the copper cap 6312 breaks, ensure that the upper shell 61 and the lower shell 62 are clamped together. After the connection between the hexagonal copper head 6313 and the copper cap 6312 breaks, the screw 631 will disengage from the sleeve 40.

[0037] The screw 631 is fitted with a butterfly spring washer 6314, which is located between the hexagonal screw head 6311 and the upper shell 61. The butterfly spring washer 6314 has excellent elastic energy storage capacity and provides axial elastic force after the screw 631 is pre-tightened, which counteracts the tendency of the screw 631 to loosen due to vibration, thermal expansion and contraction or mechanical impact. The washer is located between the hexagonal screw head 6311 and the upper shell 61, which can disperse the concentrated stress when the screw 631 is locked into a uniform surface pressure, and prevent the upper shell 61 from cracking or deforming due to excessive local stress.

[0038] The upper shell 61 is located between the two fixing blocks 2. The upper shell 61 has a slot 611 on both sides. Pushing the upper shell 61 between the fixing blocks 2 until the locking tongue 71 is engaged in the slot 611 completes the positioning and fixing of the upper shell 61. At the same time, it squeezes the hexagonal copper head 6313 to prevent the upper shell 61 from moving and affecting the connection between the sleeve 40 and the hexagonal copper head 6313.

[0039] The lower shell 62 is located between the two clamping rods 31. The two clamping rods 31 clamp the lower shell 62 to prevent it from moving or shaking, which would affect the change in the opening distance of the wire clamp 6 and thus affect the installation of the main line.

[0040] It should be noted that the clamping rod 31 is threaded and is threaded to the fixing plate 3. By manually twisting the clamping rod 31, the lower shell 62 is clamped. The end of the clamping rod 31 facing the lower shell 62 is rounded. When the lower shell 62 is clamped, the lower shell 62 can be moved by a large external force, thus preventing the clamping rod 31 from affecting the movement of the lower shell 62 under the push of the clamping plate 632.

[0041] The upper shell 61 has two guide rods on the side facing the lower shell 62 in the middle. Each guide rod has a through hole 521. One end of the through hole 521 passes through one end of the guide rod, and the other end passes through the other end of the guide rod and extends through the upper shell 61. The lower shell 62 has two through slots in the middle, and the positions of the two through slots correspond to the positions of the two guide rods. The guide rods are slidably connected in the through slots. The guide rods and through slots form a sliding fit guide structure, providing precise movement trajectory guidance during the closing process of the upper shell 61 and the lower shell 62, effectively preventing misalignment and skew. The two guide rods are symmetrically arranged in the middle to form a stable double guide post support structure, preventing the lower shell 62 from rotating during movement and ensuring the stability of the lower shell 62 during movement. One end of each of the two screws 631 passes through the two through holes 521 of the upper shell 61 and the two through slots of the lower shell 62, and is threaded into the two screw holes of the clamping plate 632.

[0042] It should be noted that the vertical cross-section of the through slot is fan-shaped, with the end closer to the upper shell 61 being smaller and the end farther from the upper shell 61 being larger. When the lower shell 62 is placed freely, the lower shell 62 is in an inclined state, making the space between the lower shell 62 and the upper shell 61 fan-shaped, with the upper part being larger than the lower part. The lower part of the space is pre-positioned manually with the slave wire, which is clamped by two clamping mechanisms 5. The upper part of the space is used for remote placement of the main wire. The space is relatively large, which facilitates remote placement and increases the accuracy of placement.

[0043] The upper shell 61 has two vertically distributed first arc-shaped grooves 612 on the side facing the lower shell 62. The two first arc-shaped grooves 612 are located on the upper and lower sides of the guide rod, respectively. Each of the two first arc-shaped grooves 612 contains a first arc-shaped conductive plate. The two first arc-shaped conductive plates are connected by a first connecting plate to form a first conductive group. The lower shell 62 has two vertically distributed second arc-shaped grooves 621 on the side facing the upper shell 61. The two second arc-shaped grooves 621 are located on the upper and lower sides of the through groove, respectively. Each of the two second arc-shaped grooves 621 contains a second arc-shaped conductive plate. The two second arc-shaped conductive plates are connected by a second connecting plate to form a second conductive group. The first and second arc-shaped conductive plates have an arc-shaped structure, which can achieve surface contact or near-surface contact with the surface of the circular wire, significantly increasing the effective conductive area. The second arc-shaped conductive plates on the lower shell 62 and the first arc-shaped conductive plates on the upper shell 61 can simultaneously clamp the slave wire and the main wire in the middle, so that the slave wire and the main wire are electrically connected.

[0044] Further explanation of this embodiment: the space between the upper shell 61 and the lower shell 62 and the space in the middle of the fixing plate 3 form a channel with an upper opening, allowing the main wire to enter the channel through the upper opening, located between the upper shell 61 and the lower shell 62, and between the upper first arc groove 612 and the second arc groove 621. The secondary wire directly enters from one side of the channel, enters between the upper shell 61 and the lower shell 62, and is located between the lower first arc groove 612 and the second arc groove 621. The secondary wire is clamped by the clamping mechanism 5.

[0045] The upper shell 61 and the lower shell 62 are both made of insulating material, and the first conductive group and the second conductive group are both made of conductive material.

[0046] Further explanation of this embodiment can be found in the following reference: Figure 1 As shown, a battery 9 is installed on one side of the base plate 1. The battery 9 is electrically connected to the small motor 53, the large motor 41 and the servo motor 81.

[0047] Further explanation of this embodiment can be found in the following reference: Figure 1 As shown, a support rod 11 is provided at the bottom of the base plate 1, and the end of the support rod 11 away from the base plate 1 is used to connect with the insulating rod.

[0048] Instructions for using live electrical contact devices: S1. Place the wire clip 6 on the base plate 1; S2. Move screw 631 and engage the hexagonal copper head 6313 at one end of screw 631 into sleeve 40; S3. Move the upper shell 61 between the two fixed blocks 2 until the locking tongue 71 is engaged in the slot 611. At the same time, the upper shell 61 presses the hexagonal copper head 6313 to fix the connection between the hexagonal copper head 6313 and the sleeve 40. S4. Move the lower shell 62 between the two clamping rods 31, manually twist the two clamping rods 31, and the two clamping rods 31 clamp and fix the lower shell 62. S5. The wire will pass through the channel from the side with the speaker guide 564, enter between the upper shell 61 and the lower shell 62, and be located between the first arc groove 612 and the second arc groove 621 in the lower part. S6. Start the small motors 53 on both sides. The small motors 53 drive the active gear 532 to rotate clockwise through the reduction gearbox 531. The active gear 532 drives the driven gear 541 to rotate. The driven gear 541 drives the lead screw 54 to rotate. The small slider 52 moves towards the large slider 51 on the lead screw 54 through the nut 522. During the movement, the elastic force of the first spring 55 gradually increases. The elastic force of the first spring 55 pulls the small slider 52, the large slider 51, the lead screw 54, and the small motor 53 together to slide away from the large slider 51 on the limit slide bar 561. At this time, the small motor 53 continues to rotate until it clamps the slave wire 6, completing the fixation of the slave wire at both points. S7. Lift the live contact device to the vicinity of the main line using the insulating rod, so that the main line enters the channel through the upper opening, located between the upper shell 61 and the lower shell 62, and between the first arc groove 612 and the second arc groove 621 in the upper part. S8. Start the large motor 41. The large motor 41 drives the drive disk 42 to rotate. The drive disk 42 drives the first conical tooth 421 to rotate. The first conical tooth drives the second conical tooth 432 to rotate, thereby driving the first rotating rod 431 to rotate. The first rotating rod 431 drives the driving tooth 43 to rotate. The driving tooth 43 simultaneously drives the first driven tooth 44 and the second driven tooth 45 to rotate, thereby driving the two sleeves 40 to rotate simultaneously. S9. The sleeve 40 drives the screw 631 to rotate through the hexagonal copper head 6313. Since the fixing screw 631 of the upper shell 61 does not move, the clamping plate 632 will move relative to it. The clamping plate 632 pushes the lower shell 62 closer to the upper shell 61, so that the lower shell 62 is released from the clamping rod 31 until the lower shell 62 is tightly attached to the upper shell 61, clamping the main wire and the secondary wire in the middle. The main wire and the secondary wire are clamped in the upper shell 61 and the lower shell 62, completing the connection of the main wire and the secondary wire. At this time, the sleeve 40 rotates. When the force of twisting the hexagonal copper head 6313 reaches a certain level, the connection between the hexagonal copper head 6313 and the copper cap 6312 breaks, so that the screw 631 is released from the connection with the sleeve 40. S10. Start the small motors 53 on both sides. The small motors 53 drive the active gear 532 to rotate counterclockwise through the reduction gearbox 531. The active gear 532 drives the driven gear 541 to rotate. The driven gear 541 drives the lead screw 54 to rotate. The small slider 52 moves away from the large slider 51 on the lead screw 54 through the nut 522. When it moves to the end of the mounting platform 56, the lead screw 54 moves relative to the small slider 52, so that the large slider 51 and the small motor 53 slide away from the small slider 52 together with the lead screw 54 on the limit slide bar 561. When the sensing convex plate 511 at the bottom of the large slider 51 moves to the position of the photoelectric sensor 563, the small motor 53 stops running, completing the release of the slave wire. S11. Activate the servo motors 81 on both sides. The servo motors 81 drive the connecting arm 82 to rotate around the output shaft of the servo motor 81. The connecting arm 82 drives one end of the lever 84 to move downward through the connecting rod 83. The other end of the lever 84 moves to the left or right (describing the levers 84 on both sides). The lever 84 moves the protruding rod 712 in the long groove 211, so that the locking tongue 71 moves out of the slot 611 and retracts into the groove 21, releasing the positioning of the upper shell 61. S12. Pull the live connection device down by the insulating rod to disengage the live connection device from the clamp 6, thus completing the live connection.
