Description

Technical Field

[0001] This invention relates to the field of insulating cover installation technology, specifically to a remote-controlled insulating cover installation tool for live-line work. Background Technology

[0002] In the operation and maintenance of power systems, live-line work is a key means to ensure the continuous and stable operation of the power grid, which can avoid economic losses and impacts on people's livelihoods caused by power outages for maintenance. However, the live-line work environment is complex, and workers need to directly or indirectly contact high-voltage live components, facing safety risks such as electric shock and arc burns. Therefore, stringent requirements are placed on the reliability, safety and convenience of insulation protection equipment and remote operation tools. At present, the insulation protection devices used in live-line work are mostly traditional insulation covers, and their materials are mostly ordinary rubber or resin materials.

[0003] Publication No. CN103730871B discloses a bird-proof insulating cover assembly that can be installed under power. It mainly consists of a cover made of insulating material that can be fitted over two in-phase porcelain insulators and a matching insulating operating rod. The cover has wire conduits at both ends of the two in-phase porcelain insulators, with the conduit holes communicating with the inner cavity of the cover. Each of the wire conduits has a protruding operating hook hole. The insulating operating rod consists of a straight rod and two forked rods at the ends of the straight rod. The distance is the same as the distance between the two operating hook holes, and the ends of the two forks are inserted into the corresponding two operating hook holes; it has the characteristics of simple structure, convenient use, good safety and reliability, and can effectively prevent bird damage. However, the installation and disassembly of traditional insulating covers mostly rely on manual close-range operation. Operators need to complete a series of actions such as positioning and fixing in a high-pressure environment. Not only is the labor intensity high, but it is also very easy to cause safety accidents due to accidental contact or improper operation during the operation. The work efficiency is also difficult to improve, the installation efficiency is low, and it is not safe and reliable enough. Summary of the Invention

[0004] The purpose of this invention is to provide a remote-controlled insulating cover installation tool for live-line work, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote-controlled insulating cover installation tool for live-line work, comprising an operating rod, a remote control module fixedly connected to the top of the operating rod, and two symmetrically arranged connecting frames connected to the side wall of the remote control module via a moving mechanism, two symmetrically arranged clamps fixedly connected to the side wall of the connecting frame, and multiple sets of fasteners fixedly inserted into the opposite side wall of the two clamps, with each set of fasteners consisting of two fasteners.

[0006] Preferably, the moving mechanism includes a U-shaped plate fixedly connected to the side wall of the remote control module, and a double-ended lead screw is rotatably connected to the side wall of the U-shaped plate. The threaded part of the double-ended lead screw is threadedly connected to two sliders, and the sliders slide on the side wall of the U-shaped plate. The connecting frame is fixed to the side wall of the sliders, and the rotation of the double-ended lead screw is driven by a driving component.

[0007] Preferably, the driving component includes a precision motor, and the output end of the precision motor is fixed to the lower end of the double-ended lead screw.

[0008] Preferably, the opposite sidewalls of the buckle are all fixedly connected to a semi-circular cover, and a limiting mechanism is provided on the opposite sidewalls of one group of the semi-circular covers. The limiting mechanism includes a fixing block fixedly connected to the bottom of the semi-circular cover. The sidewall of the fixing block is connected to a first limiting block through a first spring telescopic rod, and the first limiting block includes a first inclined surface. The movement of the first limiting block is pushed by a pushing mechanism.

[0009] Preferably, the pushing mechanism includes a strip-shaped opening at the bottom of the semi-circular cover, and a movable block is slidably connected inside the strip-shaped opening. The bottom of the movable block is fixed to the top of the first limiting block, and a pushing plate is fixedly connected to the top of the movable block. The side wall of the pushing plate is provided with a sliding groove, and the sliding groove includes an inclined groove and a vertical groove that are adjacent to each other. The movement of the pushing plate is driven by the pushing assembly.

[0010] Preferably, the pushing assembly includes a fixed tube fixedly connected to the top of the semi-circular cover, and a movable rod is inserted into the fixed tube. The movable rod is fixed to the top of the fixed tube by a first spring. The lower end of the movable rod passes through the bottom of the semi-circular cover, and a connecting plate is fixedly connected to the side wall of the movable rod. A pushing pin is fixedly connected to the side wall of the connecting plate, and the pushing pin is inserted into a sliding groove. A limiting assembly for limiting the connecting plate is provided inside the semi-circular cover.

[0011] Preferably, the limiting component includes a rectangular cover fixedly connected to the bottom of the semi-circular cover, and a movable plate is slidably connected inside the rectangular cover via a reset member. The side wall of the movable plate is fixedly connected to a plurality of arrayed second limiting blocks, and the second limiting blocks include a second inclined surface. The side wall of the connecting plate is fixedly connected to a limiting rod, and the movement of the movable plate is driven by a pusher.

[0012] Preferably, the reset element includes a second spring fixedly connected between the movable plate and the rectangular cover.

[0013] Preferably, the pushing member includes a pushing rod fixedly connected to the side wall of the movable plate, and the pushing rod is disposed through the side wall of the semi-circular cover.

[0014] Preferably, the side wall of the clamp is provided with two sets of centering mechanisms, and each set of centering mechanisms includes two V-shaped plates. The side wall of each V-shaped plate is connected to a mounting bracket through a second spring telescopic rod, and the mounting bracket is fixed to the side wall of the clamp.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This remote-controlled insulating cover installation tool for live-line work, through the inclusion of a moving mechanism, allows for the following steps: The insulating cover is placed in a semi-open state, and silicone rubber pressure-sensitive sealant is applied to the mating surfaces. Next, the positioning holes of the insulating cover are aligned with the fasteners for positioning. Then, the operating lever is held, and the insulating cover is placed over the live-line installation component. The precision motor is then activated, causing the double-ended lead screw to rotate, which in turn moves the two sliders closer together. Simultaneously, the connecting bracket moves the two clamps closer together, closing the insulating cover and securing it to the live-line installation component with silicone rubber pressure-sensitive sealant. Finally, the moving mechanism moves the two clamps away from each other, allowing the fasteners to be removed from the positioning holes. This method facilitates the installation of the insulating cover, making it more convenient, faster, safer, and more reliable.

[0016] This remote-controlled insulating cover installation tool for live-line work, through the setting of a limiting mechanism, allows for installation by fitting the positioning hole of the insulating cover onto the side wall of the semi-circular cover. During fitting, the push rod is manually pushed, causing the moving plate to move into the rectangular cover. The second spring is compressed, and the second limiting block no longer limits the limiting rod. At this time, the inner wall of the positioning hole slides along the first inclined surface, pushing the first limiting block towards the fixed block. Simultaneously, the first spring telescopic rod is compressed. When the positioning hole passes the first limiting block, the first limiting block can move away from the fixed block under the action of the first spring telescopic rod. The first limiting block and the clamps can limit the insulating cover, providing stability and reliability before the insulating cover is closed, preventing loosening or even falling off. When the two clamps move closer to each other, and when the two moving rods abut, the moving rods move into the fixed tube, and the first spring... The insulation cover is compressed, and simultaneously, the connecting plate drives the push pin to slide along the inclined groove to the vertical groove, thereby pushing the push plate to move. The moving block drives the first limiting block to move closer to the fixed block. At this time, the first limiting block no longer limits the insulation cover. When the connecting plate moves upward, it can drive the limiting rod to move upward synchronously, and the limiting rod slides upward along the second inclined surface, which can push the moving plate to move into the rectangular cover. The second spring is compressed. When the limiting rod passes the second limiting block, the second limiting block can limit the limiting rod, ensuring that the first limiting block is in the retracted state. When the two clamps continue to move closer, the insulation cover can be closed, and the silicone rubber pressure-sensitive sealant can be pressed against each other to achieve a seal. Then, the moving mechanism drives the two clamps to move closer to each other, which facilitates the separation of the semi-circular cover from the insulation cover, avoids lifting the installed insulation cover, and ensures the installation effect.

[0017] This remote-controlled insulating cover installation tool for live-line work, by setting up a centering mechanism, allows the V-shaped plate to move closer together during installation by means of a second spring telescopic rod. This causes the V-shaped plate to abut against the insulating part of the live-line installation component, thus centering the insulating cover and ensuring the installation effect. After the centering adjustment is completed, the second spring telescopic rod can be gradually compressed as the two clamps continue to move closer together. Attached Figure Description

[0020] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10 This invention provides a remote-controlled insulating cover installation tool for live-line work, including an operating lever 1. A remote control module 11 is fixedly connected to the top of the operating lever 1, and two symmetrically arranged connecting frames 12 are connected to the side wall of the remote control module 11 through a moving mechanism. Two symmetrically arranged clamps 13 are fixedly connected to the side wall of the connecting frame 12, and multiple sets of fasteners 14 are fixedly inserted into the opposite side wall of the two clamps 13. Each set of fasteners 14 has two fasteners, which facilitates the installation of the insulating cover 16, making it more convenient, faster, safer and more reliable.

[0022] Please see Figures 1-3 The moving mechanism includes a U-shaped plate 201 fixedly connected to the side wall of the remote control module 11, and a double-ended lead screw 202 rotatably connected to the side wall of the U-shaped plate 201. Two sliders 203 are threadedly connected to the threaded part of the double-ended lead screw 202, and the sliders 203 slide on the side wall of the U-shaped plate 201. The connecting frame 12 is fixed to the side wall of the sliders 203, and the rotation of the double-ended lead screw 202 is driven by a driving component. The driving component drives the double-ended lead screw 202 to rotate, thereby causing the two sliders 203 to move away from or towards each other, and the connecting frame 12 drives the two clamps 13 to move.

[0023] Please see Figure 3 The driving component includes a precision motor 10, and the output end of the precision motor 10 is fixed to the lower end of the double-ended lead screw 202. When the precision motor 10 is started, the rotation of the precision motor 10 drives the rotation of the double-ended lead screw 202.

[0024] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8 Each of the opposite sidewalls of the buckle 14 is fixedly connected to a semicircular cover 301. One set of opposite sidewalls of the semicircular covers 301 is provided with a limiting mechanism. The limiting mechanism includes a fixing block 302 fixedly connected to the bottom of the semicircular cover 301. The sidewall of the fixing block 302 is connected to a first limiting block 304 via a first spring telescopic rod 303. The first limiting block 304 includes a first inclined surface 305. The movement of the first limiting block 304 is achieved by a pushing mechanism. During installation, the positioning hole 1601 of the insulating cover 16 is fitted onto the sidewall of the semicircular cover 301. At this time, the inner wall of the positioning hole 1601 slides along the first inclined surface 305, allowing the cover to be pushed... The first limiting block 304 moves towards the fixed block 302, and at the same time, the first spring telescopic rod 303 is compressed. When the positioning hole 1601 passes the first limiting block 304, the first limiting block 304 can move away from the fixed block 302 under the action of the first spring telescopic rod 303. The first limiting block 304 and the clamp 13 can limit the insulating cover 16. It can limit the insulating cover 16 before it closes, making it more stable and reliable, and preventing loosening or even falling off. When the two clamps 13 move closer to each other, the pushing mechanism pushes the first limiting block 304 towards the fixed block 302.

[0025] Please see Figure 5The pushing mechanism includes a strip-shaped opening 401 at the bottom of the semi-circular cover 301, and a movable block 402 is slidably connected inside the strip-shaped opening 401. The bottom of the movable block 402 is fixed to the top of the first limiting block 304, and a pushing plate 403 is fixedly connected to the top of the movable block 402. The side wall of the pushing plate 403 is provided with a sliding groove, and the sliding groove includes an inclined groove 404 and a vertical groove 405 that are adjacent to each other. The movement of the pushing plate 403 is driven by the pushing component, which pushes the pushing plate 403 to move, and drives the first limiting block 304 to move through the movable block 402.

[0026] Please see Figure 4 and Figure 5 The pushing assembly includes a fixed tube 501 fixedly connected to the top of the semi-circular cover 301, and a moving rod 502 inserted inside the fixed tube 501. The moving rod 502 is fixed to the top of the fixed tube 501 by a first spring. The lower end of the moving rod 502 passes through the bottom of the semi-circular cover 301, and a connecting plate 503 is fixedly connected to the side wall of the moving rod 502. A pushing pin 504 is fixedly connected to the side wall of the connecting plate 503, and the pushing pin 504 is inserted into a groove. The semi-circular cover 301 is provided with a mechanism for moving the connecting plate 503. When the two clamps 13 move closer to each other, and the two moving rods 502 abut against each other, the moving rods 502 move into the fixed tube 501, and the first spring is compressed. At the same time, the connecting plate 503 drives the push pin 504 to slide along the inclined groove 404 to the vertical groove 405, thereby pushing the push plate 403 to move. The moving block 402 drives the first limiting block 304 to move closer to the fixed block 302. At this time, the first limiting block 304 no longer limits the insulating cover 16.

[0027] Please see Figure 9 The limiting component includes a rectangular cover 601 fixedly connected to the bottom of the semi-circular cover 301, and a movable plate 602 is slidably connected inside the rectangular cover 601 via a reset member. A plurality of arrayed second limiting blocks 603 are fixedly connected to the side wall of the movable plate 602, and the second limiting block 603 includes a second inclined surface 604. A limiting rod 605 is fixedly connected to the side wall of the connecting plate 503, and the movement of the movable plate 602 is pushed by a pusher. When the connecting plate 503 moves upward, it can drive the limiting rod 605 to move upward synchronously, and make the limiting rod 605 slide upward along the second inclined surface 604, which can push the movable plate 602 into the rectangular cover 601. The second spring 7 is compressed. When the limiting rod 605 passes the second limiting block 603, the second limiting block 603 can limit the limiting rod 605, ensuring that the first limiting block 304 is in the retracted state.

[0028] Please see Figure 9The reset component includes a second spring 7 fixedly connected between the movable plate 602 and the rectangular cover 601, which plays a reset role in the movement of the movable plate 602.

[0029] Please see Figure 4 , Figure 5 and Figure 9 The pushing component includes a pushing rod 8 fixedly connected to the side wall of the moving plate 602, and the pushing rod 8 is disposed through the side wall of the semi-circular cover 301. By pushing the pushing rod 8 by hand, the moving plate 602 moves into the rectangular cover 601, the second spring 7 is compressed, and the second limiting block 603 no longer limits the limiting rod 605, ensuring that the first limiting block 304 can move and reset.

[0030] Please see Figure 2 and Figure 3 The side wall of the clamp 13 is provided with two sets of centering mechanisms, and each set of centering mechanisms includes two V-shaped plates 901. The side wall of each V-shaped plate 901 is connected to a mounting bracket 903 through a second spring telescopic rod 902, and the mounting bracket 903 is fixed to the side wall of the clamp 13. During installation, when the two clamps 13 move closer to each other, the second spring telescopic rod 902 drives the V-shaped plates 901 to move closer to each other, so that the V-shaped plates 901 abut against the insulating part of the live installation component 15, which can center the insulating cover 16 and ensure the installation effect. After the centering adjustment is completed, when the two clamps 13 continue to move closer to each other, the second spring telescopic rod 902 can be gradually compressed.

[0031] Working principle: In use, the insulating cover 16 is in a semi-open state, and silicone rubber pressure-sensitive sealant 17 is adhered to the mating surface. Then, the positioning hole 1601 of the insulating cover 16 is fitted onto the side wall of the semi-circular cover 301. During fitting, the push rod 8 is pushed by hand, causing the moving plate 602 to move into the rectangular cover 601. The second spring 7 is compressed, and the second limiting block 603 no longer limits the limiting rod 605. At this time, the inner wall of the positioning hole 1601 slides along the first inclined surface 305. The first limiting block 304 can be pushed to move closer to the fixed block 302. At the same time, the first spring telescopic rod 303 is compressed. When the positioning hole 1601 passes the first limiting block 304, the first limiting block 304 can move away from the fixed block 302 under the action of the first spring telescopic rod 303. The first limiting block 304 and the clamp 13 can limit the insulating cover 16. The insulating cover 16 can be limited before it is closed, which is more stable and reliable and avoids loosening or even falling off.

[0032] Next, hold the operating lever 1 and place the insulating cover 16 on the outside of the live installation component 15. Then, start the precision motor 10. The rotation of the precision motor 10 drives the rotation of the double-ended lead screw 202, thereby causing the two sliders 203 to move closer to each other. At the same time, the connecting frame 12 drives the two clamps 13 to move closer to each other. When the two clamps 13 move closer to each other, the second spring telescopic rod 902 drives the V-shaped plate 901 to move closer to each other, so that the V-shaped plate 901 abuts against the insulating part of the live installation component 15, which can center the insulating cover 16 and ensure the installation effect. After the centering adjustment is completed, when the two clamps 13 continue to move closer to each other, the second spring telescopic rod 902 can be gradually compressed.

[0033] When the two clamps 13 move closer to each other, and the two moving rods 502 abut against each other, the moving rods 502 move into the fixed tube 501, compressing the first spring. Simultaneously, the connecting plate 503 drives the push pin 504 to slide along the inclined groove 404 to the vertical groove 405, thus pushing the push plate 403 to move. The moving block 402 then drives the first limiting block 304 to move closer to the fixed block 302. At this point, the first limiting block 304 no longer limits the insulating cover 16. Furthermore, when the connecting plate 503 moves upward, it drives the limiting rod 605 to move upward synchronously, causing the limiting rod 605 to move along the second inclined surface. Sliding 604 upwards pushes the moving plate 602 into the rectangular cover 601, compressing the second spring 7. When the limiting rod 605 passes the second limiting block 603, the second limiting block 603 limits the limiting rod 605, ensuring that the first limiting block 304 is in the retracted state. When the two clamps 13 continue to move closer, the insulating cover 16 closes, and the silicone rubber pressure-sensitive sealant 17 abuts against each other, achieving a sealed fixation. Then, the moving mechanism drives the two clamps 13 to move closer to each other, facilitating the separation of the semi-circular cover 301 from the insulating cover 16, preventing the installed insulating cover 16 from being lifted, and ensuring the installation effect.
