[0002] Insulating covers are insulating covers placed over connection points to prevent short circuits or leakage at the connection points of wires or cables. Existing insulating cover installation devices have poor structural stability, and a better-performing live-line installation device for insulating covers needs to be designed.

[0003] In the prior art, patent publication number CN119813011A discloses a live-line working adaptive clamp insulation cover replacement and installation device, which relates to the field of live-line working equipment technology. It includes a fixing mechanism comprising a left fixing plate and a right fixing plate spaced apart; and a closing mechanism comprising an upper left contoured aluminum plate, a lower left contoured aluminum plate, an upper right contoured aluminum plate, and a lower right contoured aluminum plate. A pair of upper left contoured aluminum plates are disposed on the upper inner wall of the left fixing plate, and a pair of lower left contoured aluminum plates are disposed on the lower inner wall of the left fixing plate; a pair of upper right contoured aluminum plates are disposed on the upper inner wall of the right fixing plate. On the wall, a pair of lower right contoured aluminum plates are set on the lower inner side of the right fixed plate; the upper left contoured aluminum plate matches the upper right contoured aluminum plate, and the lower left contoured aluminum plate matches the lower right contoured aluminum plate; the rotating fixing mechanism includes two connecting rods fixed to the left fixed plate and the right fixed plate, and a connecting seat. The other end of the connecting rod is rotatably connected to the connecting seat. The connecting seat is provided with a driving mechanism to drive the two connecting rods to rotate away from each other or close to each other. An insulating rod is connected to the bottom of the connecting seat. The installation device of the comparative patent has an unstable overall structure and cannot achieve parallel clamping when the insulating cover is installed. The clamping is not stable enough. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing installation devices cannot achieve parallel clamping and have poor clamping effect. This invention is equipped with a driving unit, which drives the side rod to achieve parallel clamping and has a good clamping effect.

[0005] Another objective of this invention is to address the issue of the heavy structure of existing installation devices. This invention features a hollow section and can be operated via a sliding rope, eliminating the need for a motor and resulting in a lighter overall weight.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an insulating cover live installation device, including a clamping part, one end of the clamping part is connected to a driving part, one side of the driving part is connected to a hand-held part, the clamping part is provided with symmetrical positioning plates, the positioning plates are connected to the cover, and the driving part drives the cover on both sides to close in parallel.

[0007] Preferably, the drive unit includes a connecting plate, a fixing plate is provided at the bottom of the connecting plate, the fixing plate is connected to a sliding plate by a spring, the two sides of the sliding plate are engaged in the sliding grooves provided on the connecting plate, and the sliding plate is provided with holes for connecting sliding ropes.

[0008] Preferably, a support rod is provided at the lower position of the connecting plate. Two parallel side rods are provided on one side of the support rod, and two parallel side rods are also provided on the other side. The sliding plate is rotatably connected to the two inner side rods by the support rod. The two side rods are respectively connected to the inclined support block at one end of the clamping part. The inclined support block is connected to the positioning plate by the limiting groove.

[0009] Preferably, the hand-held part includes an upper positioning block, a lower positioning block, and a wrench positioning block. The upper positioning block is provided with an upper pulley, the lower positioning block is provided with a lower pulley, and a wrench is rotatably connected to one side of the wrench positioning block. The wrench is provided with a hole for connecting a sliding rope.

[0010] Preferably, one end of the sliding rope is connected to a hole in the sliding plate, and the other end passes through the upper pulley and lower pulley and is fixed to a hole in the wrench.

[0011] Preferably, when the wrench is pulled down, the sliding rope drives the sliding plate downward, which in turn drives the support rods on both sides, and then drives the side rods on both sides, so that the diagonal support block drives the positioning plate to move in parallel. After the wrench is pulled back, the spring is also released, and the sliding plate is reset.

[0012] Preferably, the handle is also provided with a tension adjustment seat, which has an adjustment knob.

[0013] As a preferred option, the positioning plate has a hollowed-out section.

[0014] Preferably, the clamp is provided with a connecting seat, and the positioning plate is fixed to the connecting seat by the connecting post on its side.

[0015] Preferably, the inside of the jacket is also provided with a first fixing position and a second fixing position, which together fix the insulating cover.

[0016] Compared with existing technologies, the advantages of this invention are as follows: By incorporating a driving unit that can actuate the side rod, parallel clamping is achieved. This parallel clamping method significantly improves the accuracy and stability of clamping compared to existing installation devices, ensuring uniform force on the clamped object and effectively avoiding problems such as slippage and damage caused by non-parallel clamping. This guarantees efficient and reliable clamping operations and significantly improves the quality of the clamping process.

[0017] This invention features a hollowed-out section, which, while ensuring the structural strength of the installation device meets usage requirements, removes some redundant materials, thus reducing its weight. Simultaneously, the use of a sliding rope for operation avoids the need for bulky power equipment such as motors, further reducing the overall weight of the installation device. This makes the installation device lighter and more flexible, facilitating installation in various scenarios and reducing the requirements for the installation environment and the labor intensity during installation.

[0024] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example 1: Refer to Figures 1 to 5 An insulating cover live-line mounting device is disclosed, comprising a clamping part 1, one end of which is connected to a driving part 4. The operation of the driving part can control the movement of the clamping part, thereby achieving precise control of the insulating cover. On the other side of the driving part, a handheld part 2 is carefully connected, a design that allows the operator to conveniently and stably hold the entire device, providing a solid foundation for its flexible operation.

[0026] The positioning plate ensures the accuracy of the insulating cover's position during installation, preventing misalignment. The positioning plate is cleverly connected to the clamping cover 14, which is the component that directly contacts and clamps the insulating cover. The drive unit is designed to drive the clamping covers on both sides in a parallel closing motion. This parallel closing method ensures a uniform distribution of clamping force on the insulating cover, preventing damage due to uneven clamping. It also ensures the stability and reliability of the installation process, providing strong support for the rapid and safe installation of the insulating cover in live-line working environments.

[0027] The drive unit is mainly composed of a connecting plate 42, which plays a crucial role in connecting and supporting the entire drive unit. At the bottom of the connecting plate, a fixing plate 41 is provided, which provides stable support and fixation for the entire drive structure, ensuring that the drive unit will not experience any instability such as shaking or loosening during operation.

[0028] The fixed plate and the sliding plate 45 are cleverly connected by a spring 43. The spring provides the sliding plate with flexible extension and contraction within a certain range. This elastic connection effectively adapts to various minor changes during installation, such as differences in the size of the insulating cover or slight fluctuations in the installation environment, enhancing the adaptability and flexibility of the device. Simultaneously, the two sides of the sliding plate precisely engage with specially designed grooves on the connecting plate. This matching design of the grooves and the sliding plate ensures that the sliding plate can only slide smoothly in a predetermined direction, avoiding skewing or jamming during sliding, thus improving the reliability and operational accuracy of the device.

[0029] The sliding plate is also provided with holes for connecting the sliding rope 3. This hole design is like building a sturdy "bridge" between the sliding rope and the sliding plate, so that the sliding rope can be firmly connected to the sliding plate. This allows the pulling force applied by the operator through the hand to be accurately transmitted to the sliding plate, thereby driving the coordinated operation of the entire drive structure, achieving precise control of the clamp, and ensuring that the live installation of the insulating cover can be carried out smoothly.

[0030] A support rod 44 is carefully installed at the lower part of the connecting plate. This support rod acts as a sturdy "pillar" between the drive unit and the clamping unit, playing a crucial supporting and connecting role during device operation. Two parallel side rods 47 are cleverly arranged on one side of the support rod, while two more parallel side rods are similarly carefully arranged on the other side. This symmetrical and parallel side rod arrangement provides a reliable guarantee for the stable movement of the clamping unit, ensuring uniform force transmission and smooth movement.

[0031] The sliding plate is flexibly rotatably connected to the inner side rods on both sides via the support rod 46. This rotatable connection between the support rod and the side rods gives the sliding plate the ability to flexibly adjust its angle when under force, allowing the entire structure to adapt more smoothly to various movement changes during operation. The side rods on both sides are connected to the inclined support block 11 at one end of the clamping part. As a key component connecting the side rod and the positioning plate 13, the inclined support block is provided with a limit groove 12, which restricts the movement direction and range of the positioning plate, ensuring that the positioning plate can move parallel along a predetermined path. When the drive unit operates, the sliding plate slides up and down, and through the coordinated action of a series of components such as the support rod, side rod, inclined support block, and limit groove, the positioning plate is ultimately driven to achieve parallel movement. This allows the clamp to accurately perform a parallel closing clamping operation on the insulating cover, greatly improving the accuracy and reliability of the live installation of the insulating cover, and ensuring the safety and efficiency of the operation.

[0032] The design of the handgrip fully considers the ease of use and operational precision for the operator. The handgrip mainly includes an upper positioning block 21, a lower positioning block 22, and a wrench positioning block 24. The upper and lower positioning blocks are located at the upper and lower ends of the handgrip, respectively. Together, they provide a stable structural foundation for the handgrip, ensuring that the operator can feel the stability of the device during gripping and avoiding operational errors caused by instability in the handgrip structure.

[0033] An upper pulley 211 is carefully installed on the upper positioning block, while a lower pulley 221 is correspondingly provided on the lower positioning block. As a key transmission component connecting the handheld part and the drive part, the sliding rope can significantly reduce frictional resistance by sliding on the pulley, ensuring that the pulling force applied by the operator can be efficiently and accurately transmitted to the drive part, thereby achieving precise control of the clamp.

[0034] The wrench positioning block is located on one side of the handgrip, with the wrench 241 rotatably connected to it. The wrench design provides the operator with a convenient point of leverage, allowing them to easily control the entire device's operation through wrench movements. A hole is specifically provided on the wrench for connecting the sliding rope 3. This design ensures that one end of the sliding rope is securely connected to the wrench. When the operator pulls the wrench, the sliding rope drives the entire drive structure to move synchronously, achieving the closing operation of the clamp and completing the installation of the insulating cover. When the operator releases the wrench, the spring in the drive unit automatically resets, driving the sliding plate and other related components back to their initial positions, preparing for the next operation. The entire process is simple and smooth, greatly improving the efficiency and safety of live-line installation of the insulating cover.

[0035] The sliding rope 3 plays a crucial connecting and transmission role in the operation of the entire device. One end of the sliding rope is firmly connected to a specially designed hole in the sliding plate 45, ensuring the reliability of the connection between the sliding rope and the sliding plate and being able to withstand the tension generated during operation. The other end of the sliding rope cleverly passes through the upper pulley 211 and the lower pulley 221. This double pulley guiding design not only effectively changes the direction of force on the sliding rope, reducing the difficulty for the operator to apply tension, but also ensures the stability of the sliding rope during the sliding process, preventing the sliding rope from becoming skewed, knotted, or otherwise affecting the normal operation of the device.

[0036] Finally, one end of the sliding rope is fixed in the hole on the wrench 241. This connection method precisely translates the operator's manipulation of the hand-held wrench into the up-and-down sliding motion of the sliding plate, thereby driving the operation of the entire clamping unit and enabling the installation and removal of the insulating cover. The ingenious connection of the sliding rope allows the operator to easily control the movement of the driving and clamping units from the hand-held part, greatly improving the ease of operation and flexibility of the device, and providing significant convenience for live-line installation of the insulating cover.

[0037] When the operator needs to install the insulation cover, simply pull down the wrench 241. The sliding rope 3 moves downwards under the wrench's influence. The downward pull of the sliding rope causes the sliding plate 45 to move downwards synchronously. The downward movement of the sliding plate, through the support rod 46, causes corresponding movements in the side rods 47 on both sides. The side rods on both sides are respectively connected to the inclined support block 11 at one end of the clamping part. Driven by the side rods, the inclined support block, through the connection between the limiting groove 12 and the positioning plate 13, causes the positioning plate to move parallel. Finally, the positioning plate causes the clamping cover 14 to close parallel, thus firmly clamping the insulation cover in the target position and completing the installation operation.

[0038] When the operator releases the wrench 241, the spring 43 in the drive unit 4 automatically extends and retracts, causing the sliding plate 45 to return to its initial position. The entire drive structure then resets, preparing for the next installation operation. This process is simple and smooth, requiring no complicated operating steps, greatly improving the efficiency of live-line installation work. It also reduces the difficulty and labor intensity for operators, ensuring the safety and reliability of the work. It is an ideal tool for live-line work scenarios such as power maintenance.

[0039] The handheld unit also features a tension adjustment seat 23, providing operators with a more personalized operating experience. The tension adjustment seat is equipped with an adjustment knob, allowing operators to adjust the tension of the sliding rope 3 according to their own operating habits and actual needs. This adjustment function ensures that the sliding rope maintains appropriate tension during operation, preventing issues such as insensitive operation or unstable clamping due to an overly loose rope, and avoiding increased operating difficulty or unnecessary damage to the device components due to an overly tight rope.

[0040] Example 2: Refer to Figures 1 to 5 An electrical installation device for an insulating cover includes a clamping part 1, one end of which is connected to a driving part 4, and the other side of the driving part is a handheld part 2. Symmetrically distributed positioning plates 13 are provided on the clamping part. During installation, the device can position the insulating cover with extremely high precision, effectively preventing any deviation and ensuring that the insulating cover accurately reaches the predetermined installation position. The positioning plates are tightly connected to the clamping cover 14 through a clever mechanical connection, with the clamping cover directly contacting and clamping the insulating cover. The driving part can drive the clamping covers on both sides to perform a parallel closing action like a high-precision instrument, ensuring a uniform distribution of clamping force on the insulating cover. This ensures that the insulating cover is not damaged during installation and provides a stable and reliable guarantee for the entire installation process, greatly improving the efficiency and safety of insulating cover installation in live-line working environments.

[0041] A support rod 44 is installed at the lower position of the connecting plate to smoothly and reliably transmit the power of the drive unit to the clamping unit, ensuring the smooth and continuous operation of the entire device. Two parallel side rods 47 are arranged on one side of the support rod, and two more parallel side rods are arranged on the other side, forming a symmetrical and stable layout. The sliding plate is connected to the inner side rods on both sides through a support rod 46. The side rods on both sides are connected to the inclined support block 11 at one end of the clamping unit. The inclined support block, as a key component connecting the side rods and the positioning plate 13, is provided with a precision-machined limiting groove 12. When the drive unit starts to operate, the sliding plate slides up and down under the action of the drive component. This action, through the precise coordination of a series of components such as the support rod, side rods, inclined support block, and limiting groove, ultimately drives the positioning plate to achieve precise parallel movement, thereby enabling the clamp to accurately perform parallel closing clamping operation on the insulating cover.

[0042] The handgrip mainly consists of an upper positioning block 21, a lower positioning block 22, and a wrench positioning block 24. These three parts work together to form a stable and reliable handgrip structure. The upper and lower positioning blocks are located at the upper and lower ends of the handgrip, respectively. They act like the "stabilizing anchors" of the handgrip, providing a rock-solid structural foundation and ensuring that the operator can feel the stability of the device during gripping. Even in bumpy or narrow working environments, the operator can hold the device firmly, avoiding operational errors caused by instability in the handgrip structure. This provides reliable operational assurance for the smooth progress of the entire installation operation.

[0043] An upper pulley 211 is installed on the upper positioning block, while a lower pulley 221 is correspondingly installed on the lower positioning block, which greatly reduces the frictional resistance of the sliding rope during the sliding process. As a key transmission component connecting the handheld part and the drive part, the sliding of the sliding rope on the pulley ensures that the small pulling force applied by the operator can be efficiently and accurately transmitted to the drive part, thereby achieving precise control of the clamp. This allows the operator to complete the precise installation of the insulating cover with less force, effectively reducing the operator's labor intensity.

[0044] A wrench positioning block is located on one side of the handgrip, on which a cleverly designed wrench 241 is rotatably connected. The wrench design provides the operator with a comfortable and convenient point of leverage, allowing for easy control of the entire device's operation through the wrench's back-and-forth swing motion. A sturdy hole is specifically designed in the wrench for connecting the sliding rope 3. This design ensures that one end of the sliding rope is securely connected to the wrench. When the operator pulls the wrench, the sliding rope drives the entire drive structure synchronously, achieving the closing operation of the clamp and firmly holding the insulating cover in the target position, completing the installation task. When the operator releases the wrench, the spring in the drive unit automatically resets, causing the sliding plate and other related components to quickly return to their initial position, preparing for the next operation. This greatly improves the efficiency and safety of live-line installation of the insulating cover, enabling operators to handle complex live-line work tasks with greater ease.

[0045] The other end of the sliding rope passes through the upper pulley 211 and the lower pulley 221. This double pulley guide design can not only effectively change the direction of force on the sliding rope and reduce the difficulty for operators to apply pulling force, but also ensure the stability of the sliding rope during the sliding process. It can also prevent the sliding rope from becoming skewed or knotted, which may affect the normal operation of the device, thus ensuring the accuracy and smoothness of the transmission process and improving the reliability and service life of the device.

[0046] When operators need to install insulation covers on live equipment, they simply pull the wrench 241 lightly. The sliding rope 3, driven by the wrench, moves downwards along the pulley guide. The downward pull of the sliding rope causes the sliding plate 45 to move downwards simultaneously. The downward movement of the sliding plate, in turn, drives the side rods 47 on both sides to move accordingly via the support rod 46, creating a series of intricate mechanical transmission chains.

[0047] After receiving the instruction from the sliding plate, the side rods on both sides drive the inclined support block 11 at one end of the clamping part to move. Under the push of the side rods, the inclined support block, with the help of the tight connection between the limiting groove 12 and the positioning plate 13, causes the positioning plate to move parallel along the predetermined path. The positioning plate drives the clamping cover 14 to achieve precise parallel closure, firmly clamping the insulating cover on the target equipment and completing the installation operation.

[0048] After installation, when the operator releases the wrench 241, the spring 43 in the drive unit 4 automatically extends and retracts, causing the sliding plate 45 to easily return to its initial position. The entire drive structure then precisely resets, quickly preparing for the next installation operation. A tension adjustment seat 23 is provided on the handheld part, offering the operator a better operating experience. The tension adjustment seat is equipped with an adjustment knob, allowing the operator to easily adjust the tension of the sliding rope 3 according to their operating habits, hand strength, and actual usage needs, ensuring that the sliding rope maintains appropriate tension throughout the operation.

[0049] When the sliding rope is in the appropriate tension, it can avoid situations such as insensitive operation and unstable clamping due to excessively loose sliding rope, which would affect the installation quality and efficiency. At the same time, it can also avoid increasing the difficulty of operation or causing unnecessary wear and damage to the internal components of the device due to excessively tight sliding rope, thereby extending the service life of the device. Through the design of the tension adjustment seat, the entire device can better adapt to different operating environments. Whether it is a narrow space or a complex equipment layout, or the difference in operating force between different operators, it can easily cope with it, further improving the versatility and flexibility of the device.

[0050] The positioning plate features a perforated section 131. This innovative design not only effectively reduces the weight of the positioning plate itself and lowers the operational burden of the entire device, but also significantly reduces the amount of material used, achieving both lightweight and economic efficiency. The perforated section was carefully calculated and tested to ensure that, without weakening the structural strength of the positioning plate, it can more flexibly adapt to the shape of the insulating cover during installation, improving positioning accuracy. It also helps reduce air resistance during operation, enhancing the smoothness of movement.

[0051] A connecting seat 17 is provided on the clamp, and the positioning plate is fixed to the connecting seat via a connecting post 18 on its side. This connection method greatly enhances the stability of the connection between the positioning plate and the clamp. The cooperative design of the connecting post and the connecting seat can not only withstand various forces generated during installation, but also allows for fine adjustment of the position of the positioning plate within a certain range to accommodate insulating covers of different sizes and shapes. This flexible connection mechanism enables the device to quickly respond to the diverse needs of on-site operations, improves the versatility and adaptability of the device, and ensures efficient and accurate installation of insulating covers in various complex environments.

[0052] Inside the clamp, there are also first fixing positions 15 and second fixing positions 16. These two fixing positions work together to secure the insulating cover. The first and second fixing positions are rationally distributed at key locations inside the clamp, and the clamping force is evenly distributed through multi-point contact. This ensures that the insulating cover will not be damaged due to excessive local force, nor will it loosen or shift due to uneven force during installation. This multi-point fixing mechanism greatly improves the installation stability of the insulating cover, enabling it to maintain good electrical insulation performance in the complex electromagnetic environment of live-line work, effectively ensuring the safety and reliability of the operation.

[0053] For those skilled in the art, the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
