Abstract
Description
Technical Field
[0001] This invention belongs to the field of live-line working technology, and particularly relates to a method for connecting and disconnecting live-line working lines based on a hoisting platform. Background Technology
[0002] Live-line work is gradually shifting from conventional manual labor to a combination of robotic and human methods. A significant portion of live-line work involves splicing live conductors. When performing this work, personnel must conduct site surveys, confirm the work plan, and determine whether to use a boom lift or personnel climbing the pole, based on the site conditions. This is primarily due to the limitations imposed by varying work environments. Because the initial power grid construction did not consider the limitations of live-line work, some work areas are too small for insulated boom lifts to access. Furthermore, the high cost of boom lifts and the limited availability in some areas mean that pole climbing is often the only option. This places higher demands on personnel, hindering the development and application of live-line work, significantly impacting maintenance work, and reducing power supply reliability.
[0003] Therefore, there is an urgent need for a live-line operation method based on a hoisting platform to connect the diversion line in order to solve the above problems. Summary of the Invention

[0031] 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.
[0032] Please see Figure 1-7 This invention provides a technical solution: a method for live-line splicing of a guide wire based on a hoisting platform. The method is applied to a hoisting and connecting device, which completes the installation of the guide wire on the conductor. The hoisting and connecting device includes a lifting boom, a working module, a gripper mechanism, a telescopic robotic arm 12, a control terminal, and a guide wire clamp 13. The lifting boom is connected to an external hoisting device, and the working module and gripper mechanism are connected to the lifting boom. A clamping device 5 is installed at the lower part of the lifting boom. The lifting boom includes a lifting rod 6 and a lifting module 7, with the lifting module 7 enclosing the lifting rod 6. The working module includes a working platform, a stripper 8, a wire clamp installation tool 9, and a guide wire traction device 11. The stripper 8 and the wire clamp installation tool 9 are respectively installed on both sides of the working platform.
[0033] Specifically, the clamping device 5 is mainly used to fix the lifting rod 6 to the conductor to prevent the lifting rod 6 from swaying in the air, thereby causing a phase-to-phase short circuit.
[0034] Specifically, the hoisting device mainly includes a crane or other aerial work platform vehicle with hoisting function, which can lift the lifting boom and work module to the work area. Its main function is to move the device to the work area, and there is no requirement for insulation.
[0035] The lifting pole comprises bakelite 1 and rack 2, which are arranged in a sandwich structure, with bakelite 1 located on the outside of rack 2 and the two components staggered. The use of bakelite 1 as the main material gives the lifting pole high insulation performance, and its length is controlled by a modular splicing method, making it suitable for various overhead line conditions.
[0036] Specifically, the lifting rod is mainly used to connect the work platform and the hoisting device. It is mainly made of epoxy resin insulating tube and nylon rack, and a nylon clamp is installed below for fixing the work platform and the guide wire.
[0037] Specifically, the control terminal is mainly used to control the electric stripper 8 and the wire clamp installation tool 9 to perform stripping and wire clamp installation operations.
[0038] Specifically, the peeler 8 and the wire clamp installation tool 9 are installed in the rotating turntable of the work platform. The work platform can move up and down in the lifting rod through the rack 2 in the lifting rod. The rotating turntable has gears, and the tools can be selected and operated by rotating the turntable.
[0039] The lifting module includes nylon, gear 3 and motor 4. Motor 4 is fixed to one side of the lifting module and is connected to gear 3. Gear 3 meshes with rack 2 in the lifting rod. Starting motor 4 can drive gear 3 to rotate, so that it can move up and down along the lifting rod.
[0040] Specifically, in use, the working module is installed on the lifting module 7, so that the peeler 8 and the wire clamp installation tool 9 can move up and down along the lifting rod as the lifting module 7 moves.
[0041] Specifically, such as Figure 5 As shown, the work platform is equipped with a rotary module, which allows for the selection of different types of installation tools at the same location to perform the work according to the project.
[0042] The operation method of the present invention is applied to the conductor. When using it, an insulating shield 10 needs to be placed on the conductor in the area to be operated and on the porcelain insulator of the conductor.
[0043] Specifically, the gripper mechanism is used for gripping and installing the insulating shield 10 during operation.
[0044] The drain line traction device 11 is located at the lower end of the lifting rod 6. In use, the drain line traction device 11 is located below the conductor. The drain line traction device 11 mainly consists of a motor, a take-up device, a traction rope, and a line clamp limiter. It is mainly supported by nylon material, and the traction rope is made of insulated silk rope.
[0045] The telescopic robotic arm 12 is connected to the bottom end of the lifting rod 6. The telescopic robotic arm 12 is composed of a motor, an epoxy resin insulating rod, and nylon. It is used to transport the insulated silk rope and hook to the drainage line, so that the end of the telescopic robotic arm 12 hooks onto the drainage line clamp 13 in the drainage line.
[0046] The drain clamp 13 can automatically install the drain wire.
[0047] The aforementioned work platform and each work device are all powered independently and are remotely controlled by the main control computer, thus avoiding potential hazards to the power grid caused by communication lines between devices.
[0048] A method for live-line work of splicing a power supply line based on a hoisting platform includes the following steps:
[0049] S1, Install the lifting guide device onto the external lifting device; send the lifting guide device in the hook of the external lifting device to the work area and fix the boom;
[0050] S2, using the control terminal, control the winch mechanism in the hoisting device to place the hoisting connection device on the ground above the conductor and across the conductor; wherein, the cable in the winch mechanism is an insulated silk rope;
[0051] S3. Determine if the shielding environment is complex. If the environment is complex, use an insulated operating rod to complete the installation of the insulation shielding by climbing a pole. If the environment is not complex, place the hoisting and guiding device on the ground, install the insulation shielding cover 10 into the gripper mechanism of the device, and then the winch mechanism in the hoisting device will work to retrieve the insulated silk rope and lift the hoisting and guiding device to the waiting area. Then, the insulation shielding cover 10 will be placed at the conductor and porcelain insulator through the winch mechanism.
[0052] S4, control the clamping device 5 to fix the wire to prevent shaking during operation;
[0053] S5, the working platform is lowered by the lifting module 7, so that the stripper 8 on it is engaged in the main line, the stripper 8 clamps the wire, automatically cuts down and adaptively peels off the insulation layer.
[0054] S6, the drain clamp 13 is pre-installed onto the drain line. When the stripper 8 is working, the telescopic insulated manipulator is controlled so that the insulated hook at the end of the manipulator is attached to the hanging ring in the drain clamp at the end of the drain line. Then the drain line traction device 11 pulls the drain clamp 13 and the wire into the groove of the drain line traction device 11. After the stripper 8 removes the insulation layer of the wire, the working platform rotates 180 degrees and rotates the clamp installation tool 9 above the drain clamp 13.
[0055] S7, the work platform is lowered so that the wire clamp installation tool 9 is aligned with the fastening bolt of the wire clamp 13 in the groove of the wire traction device 11. Then the wire clamp installation tool 9 begins to work and the wire installation is completed.
[0056] S8. After completing the single-phase operation, move the hoisting device boom to the other phase conductor and repeat steps S4 to S7 until the installation of the three-phase conductor lead wire is completed and the live hoisting connection operation is finished.
[0057] Before the operation of the method of the present invention begins, preparatory work is required. For example... Figure 2 As shown, the first step is to explore the work site, select the appropriate work method based on the situation, and assess whether the site conditions meet the requirements for bucket truck operation. If the conditions are met, a bucket truck can be used. If not, the work environment must be surveyed to determine if a conventional crane can be used for lifting operations. If lifting conditions are not met, a conventional pole-climbing method can be used. If lifting conditions are met, a lifting method can be employed. Due to the high cost of bucket trucks and the limited availability in some areas, pole-climbing operations are often the only option. This invention addresses situations where bucket trucks are not feasible by using vehicles or devices equipped with lifting devices. Furthermore, the operation is conducted remotely by personnel, reducing personnel safety risks and the cost of using insulated bucket trucks, thus extending beyond the limitations of pole-climbing methods.
[0058] In this embodiment, the preparatory work is completed, namely, the crane mechanism is prepared; the lifting and guiding device is installed on the crane mechanism; the crane sends the lifting and guiding device in the hook to the work area and fixes the boom.
[0059] In this embodiment, the clamping device 5 is configured as an electric clamp. The electric clamp is used to secure the wire, preventing it from vibrating and detaching from the conductor during operation.
[0060] Specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
