Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and more specifically, to an electrically operated insulation device for installing and removing grounding rings. Background Technology

[0002] Grounding rings serve as protective devices to prevent overhead insulated conductors from being broken by lightning strikes, and are also used for maintenance, construction, and temporary grounding.

[0003] In the power industry, grounding wires need to be installed during the maintenance of power distribution lines or equipment to ensure the safety of maintenance personnel. The conventional method for installing grounding wires is for personnel to climb to the conductor, wear insulated gloves, lift the grounding ring until the conductor is inserted into the grounding ring, and tighten the nut on the grounding ring with an electric wrench. However, even with insulated gloves, this operation poses safety risks and threats to workers. Therefore, some have proposed using robots to install grounding rings, and the robot installation technology is already quite mature. However, the robot installation process involves first gripping the conductor and simultaneously stripping the grounding ring, then lowering the conductor, and then gripping the stripped section of the conductor again to install the grounding ring. This process requires gripping the conductor twice, and the conductor can wobble, affecting the accuracy of the grounding ring installation. Furthermore, the installation or removal of the grounding ring requires installing or removing bolts, which have a certain weight. Currently, the bolts may fall during the installation or removal of the equipment, endangering the safety of workers on the ground. Summary of the Invention

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of this invention are:

[0020] 1) When using this electric grounding ring installation and removal insulation device, the conductor is fixed by the support column, and then the outer sheath of the conductor is removed by the cutting component. Then, the first electric telescopic rod drives the first movable block to move upward so that the grounding ring is connected to the conductor. After that, the bolt is installed on the grounding ring by the bolt installation and removal component, thus completing the installation of the grounding ring. Throughout the process, the conductor is limited and will not shake. The conductor, the cutting component, and the grounding ring are on the same vertical tangent line. During the process of conductor shearing, grounding ring installation, and bolt installation, the installation of the grounding ring is more accurate only by the movement of the first electric telescopic rod, avoiding instability caused by conductor shaking during installation. The connection between the grounding ring and the conductor shearing position is also more accurate.

[0021] 2) When using this electric installation and removal insulation device for the grounding ring, a hexagonal bolt is simultaneously installed into the bolt placement hole while the grounding ring is being installed. The spring compresses the compression block, limiting the hexagonal bolt. After the cutting assembly cuts the outer sheath of the conductor, the bolt installation and removal assembly on the rotating plate is rotated 90 degrees via the rotating shaft. After the grounding ring is connected to the conductor, the second electric telescopic rod drives the support frame to approach the grounding ring, aligning the bolt with the screw hole on the grounding ring. The second motor inside the bolt installation and removal assembly drives the bolt column to rotate, connecting the bolt with the screw hole and fixing the grounding ring. This fixes the bolt to the grounding ring and prevents the bolt from falling off during movement.

[0022] 3) When this electric installation and removal insulation device for grounding ring is in use, when the wire enters the wire groove, the first motor drives the screw to rotate, so that the second movable block drives the first blade to engage with the first blade in the first fixed block and the second fixed block to cut the outer sheath of the wire. Then, the second blade cuts the outer sheath of the wire laterally to complete the cutting of the wire. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Example 1:

[0036] In the power industry, grounding wires need to be installed during the maintenance of power distribution lines or equipment to ensure the safety of maintenance personnel. The conventional method for installing grounding wires is for personnel to climb to the conductor, wear insulated gloves, lift the grounding ring until the conductor is inserted into the grounding ring, and tighten the nut on the grounding ring with an electric wrench. However, this operation still poses safety risks even when wearing insulated gloves, posing a dangerous threat to the workers. Therefore, some have proposed using robots to install grounding rings, and the robot installation technology is already quite mature. However, the robot installation steps involve first grabbing the conductor, simultaneously stripping the grounding ring, then lowering the conductor, and then grabbing the stripped section of the conductor again to install the grounding ring. This process requires grabbing the conductor twice, and the conductor will sway, affecting the accuracy of the grounding ring installation. The following solution addresses this problem.

[0037] Please see Figures 1 to 8An electrically operated grounding ring mounting and dismounting insulation device includes a base plate 1, a telescopic column 2, and a support column 3. The telescopic column 2 is disposed between the support column 3 and the base plate 1. The telescopic column 2 is a conventional telescopic device in the prior art. A support hole 4 is provided at the top of the support column 3. A first movable block 6 is movably connected to the side surface of the support column 3. Two corresponding limiting plates 9 are movably connected to the surface of the first movable block 6. The limiting plates 9 are used to limit the grounding ring. A rotating plate 14 is rotatably connected to the top of the side surface of each limiting plate 9. A support frame 15 is movably connected to the surface of each rotating plate 14. A bolt disassembly and assembly assembly is installed inside each support frame 15 to disassemble the bolts. A cutting component is provided at the end of each rotating plate 14. The cutting assembly can remove the insulation from the wire. The wire is fixed by the support column 3. Then, the wire insulation is removed by the cutting assembly. The first electric telescopic rod 8 drives the first movable block 6 to move upward, so that the grounding ring is connected to the wire. Then, the bolt installation assembly installs the bolt on the grounding ring, thus completing the installation of the grounding ring. Throughout the process, the wire is limited and will not shake. The wire, the cutting assembly, and the grounding ring are on the same vertical cutting line. During the wire insulation removal, grounding ring installation, and bolt installation, the first electric telescopic rod 8 alone drives the grounding ring to make the installation more accurate, avoiding instability caused by wire shaking during installation. The connection between the grounding ring and the wire insulation removal position is also more accurate.

[0038] As a further aspect of the present invention: a first slider 7 is provided on the side surface of the first movable block 6, and a first groove 5 matching the first slider 7 is provided on the surface of the support column 3. The first movable block 6 is slidably connected to the support column 3 through the first slider 7 provided in the first groove 5, thereby realizing the mobility of the first movable block 6. A first electric telescopic rod 8 connected to the first movable block 6 is installed on the top of the telescopic column 2. The first electric telescopic rod 8 is a conventional electric telescopic device in the prior art. The first electric telescopic rod 8 can drive the first movable block 6 to move up and down, thereby realizing the up and down movement of the grounding ring, bolt disassembly and assembly, and cutting assembly installed on the first movable block 6.

[0039] As a further aspect of the present invention: a second sliding groove 11 is provided on the front side of the first movable block 6, and a second slider 13 matching the second sliding groove 11 is provided on the surface of the limiting plate 9. The limiting plate 9 is slidably connected to the first movable block 6 through the second slider 13 provided in the second sliding groove 11, thereby realizing the movable nature of the limiting plate 9 on the first movable block 6, and thus realizing the clamping of the grounding ring.

[0040] As a further aspect of the present invention: the inner wall of the second slide groove 11 is rotatably connected to a first bidirectional screw 12 connected to the second slider 13, and the interior of the first movable block 6 on one side of the second slide groove 11 is equipped with a first motor connected to the first bidirectional screw 12. The inner side of the limiting plate 9 is provided with a slot 10. The first motor is a conventional forward and reverse reversible motor in the prior art. The first motor can drive the first bidirectional screw 12 to rotate forward and reverse, thereby realizing the reciprocating motion of the second slider 13 on the first bidirectional screw 12, and finally realizing the movement of the limiting plate 9 towards or away from each other.

[0041] As a further aspect of the present invention: a rotating shaft 32 connected to a rotating plate 14 is provided on the top of the side surface of the limiting plate 9. The rotating plate 14 is rotatably connected to the limiting plate 9 through the rotating shaft 32, thereby realizing the rotatability of the rotating plate 14. A third sliding groove 16 matching the support frame 15 is provided on the surface of the rotating plate 14. The support frame 15 is slidably connected to the rotating plate 14 through the third sliding groove 16, thereby realizing the sliding of the support frame 15 on the rotating plate 14. A second electric telescopic rod 17 connected to the support frame 15 is installed on the inner wall of the third sliding groove 16. The rotating plate 14 and the second electric telescopic rod 17 are conventional electric motor telescopic devices in the prior art. The second electric telescopic rod 17 can drive the support frame 15 to move.

[0042] The steps for using this invention are as follows: First, the operator places the grounding ring between the limiting plates 9. Then, the device is placed in a suitable position. The telescopic column 2 drives the support column 3 upward, causing the support hole 4 to lift the wire. Next, the first electric telescopic rod 8 drives the first movable block 6 upward, allowing the wire to enter the conductor groove 31. Then, the cutting device cuts the outer sheath of the wire. Next, the rotating plate 14 is rotated so that it is perpendicular to the first movable block 6 by 90 degrees. Then, the first electric telescopic rod 8 drives the first movable block 6 upward, connecting the grounding ring to the conductor. Finally, the bolt is installed on the grounding ring using the bolt assembly, thus fixing the grounding ring and completing the installation. When it is necessary to remove the grounding ring, the rotating plate 14 is rotated 90 degrees, and then the telescopic column 2... The bolt assembly is aligned with the bolt, and the bolt is then removed using the bolt assembly to disassemble the grounding ring. The grounding ring is then clamped by the limiting plate 9 and removed. This solution uses the support column 3 to fix the conductor, and then the cutting assembly removes the conductor's outer sheath. The first electric telescopic rod 8 drives the first movable block 6 upwards to connect the grounding ring to the conductor. Finally, the bolt assembly installs the bolt onto the grounding ring, completing the grounding ring installation. Throughout the process, the conductor is limited and will not shake. The conductor, cutting assembly, and grounding ring are all on the same vertical tangent line. The installation of the grounding ring is more accurate, relying solely on the first electric telescopic rod 8 during conductor sheath removal, grounding ring installation, and bolt installation. This avoids instability caused by conductor vibration during installation and ensures more accurate alignment between the grounding ring and the conductor's sheathed position.

[0043] Example 2:

[0044] When installing or removing the grounding ring, bolts need to be installed or removed. Bolts have a certain weight, and currently, bolts may fall off during the installation or removal of equipment, affecting the safety of ground personnel. The following solutions are proposed to address this issue.

[0045] Please see Figures 1 to 8The difference from Embodiment 1 lies in that the bolt assembly includes a second motor 18 and a bolt post 19. The second motor 18 is a conventional forward and reverse reversible motor, capable of driving the bolt post 19 to rotate in both directions. Forward rotation of the second motor 18 allows for bolt installation, while reverse rotation allows for bolt removal. The second motor 18 is mounted on one side of the support frame 15, and the bolt post 19, connected to the second motor 18, is rotatably connected to the other side of the support frame 15. The bolt post 19 has a bolt placement hole 20 inside for placing bolts. The inner wall of the bolt placement hole 20 has a second movable groove 33, and a spring 35 is provided on the inner wall of the second movable groove 33. A pressing block 34 is provided at the end of the spring 35, and the pressing block 34 is elastically connected to the second movable groove 33 via the spring 35. A third slider 37 is provided on the side surface of the pressing block 34. The inner wall of the second movable groove 33 is provided with a fourth sliding groove 36 that matches the third slider 37. The pressing block 34 is slidably connected to the second movable groove 33 through the third slider 37 set in the fourth sliding groove 36. When installing the grounding ring, the hexagonal bolt is installed into the bolt placement hole 20 at the same time. The spring 38 presses the pressing block 34 to limit the hexagonal bolt. After the cutting assembly cuts the outer sheath of the wire, the bolt disassembly and assembly assembly on the rotating plate 14 is rotated 90 degrees by the rotating shaft 32. After the grounding ring is connected to the wire, the second electric telescopic rod 17 drives the support frame 15 to approach the grounding ring, so that the bolt is aligned with the screw hole on the grounding ring. The second motor 18 in the bolt disassembly and assembly assembly drives the bolt column 19 to rotate so that the bolt is connected with the screw hole, thereby fixing the grounding ring. This fixes the bolt to the grounding ring and avoids the possibility of the bolt falling off during movement.

[0046] The steps of using this invention are as follows: When using this electric installation and removal insulation device for grounding rings, a hexagonal bolt is simultaneously installed into the bolt placement hole 20 while the grounding ring is being installed. The spring 38 presses against the compression block 34, limiting the hexagonal bolt. After the cutting assembly cuts the outer sheath of the conductor, the bolt installation and removal assembly on the rotating plate 14 is rotated 90 degrees by the rotating shaft 32. After the grounding ring is connected to the conductor, the second electric telescopic rod 17 drives the support frame 15 to approach the grounding ring, aligning the bolt with the screw hole on the grounding ring. The second motor 18 in the bolt installation and removal assembly drives the bolt post 19 to rotate, connecting the bolt with the screw hole and fixing the grounding ring. This solution achieves the fixing of the bolt to the grounding ring and avoids the possibility of the bolt falling off during movement.

[0047] Example 3:

[0048] As mentioned in Examples 1 and 2, the installation of the grounding ring requires stripping the wire insulation. Currently, the wire insulation stripping devices have poor stripping effect, which may cause the wire insulation to stick to the wire. The following solution is used to solve this problem.

[0049] Please see Figures 1 to 8 The difference between this embodiment and embodiments 1 and 2 lies in that the cutting assembly includes a first fixed block 21, a second fixed block 26, a second movable block 22, a first blade 25, a fixed plate 27, a wire groove 31, and a second blade 29. The first fixed block 21 and the second fixed block 26 are respectively disposed at the ends of the two rotating plates 14. The second movable block 22 is movably connected above both the first fixed block 21 and the second fixed block 26. Wire grooves 31 are provided on the surfaces of the first fixed block 21, the second fixed block 26, and the second movable block 22. The first blade 25 is disposed inside the wire groove 31. The surfaces of the first fixed block 21 and the second movable block 22 above it are both provided with fixed plates 27. The second blade 29 is movably connected inside the fixed plate 27. The interior of the second movable block 22 above the second fixed block 26 is provided with a first movable groove 30 that matches the fixed plate 27. The first motor 23 drives the screw 24 to rotate, so that the second movable block 22 drives the first blade 25 to engage with the first blade 25 in the first fixed block 21 and the second fixed block 26 to cut the outer sheath of the wire. Then, the second blade 29 is used to cut the outer sheath of the wire laterally to complete the cutting of the wire.

[0050] As a further aspect of the present invention: a first motor 23 is provided on the top of both the first fixing block 21 and the second fixing block 26. The first motor 23 is a conventional reversible motor in the prior art. The first motor 23 can drive the screw 24 to rotate in both directions. The output end of the first motor 23 is provided with the screw 24. The first fixing block 21 and the second fixing block 26 are respectively threadedly connected to the two screws 24. The inside of the fixing plate 27 is provided with a mounting groove that matches the second blade 29. The inner wall of the mounting groove is provided with a second motor. The output end of the second motor is provided with a second bidirectional screw 28 connected to the second blade 29. The second blade 29 is a conventional reversible motor in the prior art. The second motor can drive the second bidirectional screw 28 to rotate in both directions, thereby realizing the reciprocating motion of the second blade 29.

[0051] The steps of using this invention are as follows: When the electric grounding ring installation and removal insulation device is in use, when the wire enters the wire groove 31, the first motor 23 drives the screw 24 to rotate, so that the second movable block 22 drives the first blade 25 to combine with the first blade 25 in the first fixed block 21 and the second fixed block 26 to cut the wire sheath. Then, by making the second blade 29 cut the wire sheath laterally, the lateral and longitudinal cooperation makes the wire sheath removal more thorough.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
