[0002] Distribution network lines are characterized by complex lines, dense equipment, and large coverage. They are prone to failures under the influence of various external factors, and the maintenance work is relatively heavy. Therefore, the development of live-line work in distribution networks is particularly important. Live-line work in distribution networks can not only eliminate equipment defects in a timely manner, but also play a positive role in ensuring the safe operation of the power grid, reducing power outage time for users, thereby improving the reliability of power supply. Therefore, improving live-line working technology and improving live-line working tools are inevitable requirements for adapting to economic development.

[0031] To solve the above problems, see Figures 1 to 6 The present invention provides a single-phase conductor lifting device, including two clamping assemblies 1, a lifting assembly 2 and a remote control structure. A support rod 3 is arranged between the two clamping assemblies 1, and the support rod 3 is used to adjust the spacing between the two clamping assemblies 1 to be consistent with the spacing between the two cross arms 4; the lifting assembly 2 is movably connected to the support rod 3 and moves along the length direction of the support rod 3. The lifting assembly 2 is located between the two clamping assemblies 1 and is arranged parallel to the pole 6. The end of the lifting assembly 2 away from the support rod 3 has a conductor placement cavity 241. The clamping assembly 1 is used to clamp the cross arm 4 of the pole 6, and the lifting assembly 2 is used to lift the conductor away from the cross arm 4; the remote control structure is connected to the lifting assembly 2 by electrical signals to control the operation of the lifting assembly 2. Among them, the movable base 21, the conductor lifting clamp, the clamping base 11 and the clamping block 13 are all made of insulating materials, which improves the insulation performance of the device and protects the personal safety of the staff.

[0032] In an optional embodiment, if Figure 1 and Figure 2As shown, the lifting assembly 2 includes a movable base 21, a telescopic body 22 and a driving motor 23. The movable base 21 is provided with a slide slot, the support rod 3 is inserted in the slide slot, and the movable base 21 moves along the length direction of the support rod 3; one end of the telescopic body 22 is provided with a wire lifting clamp, and the other end is inserted in the movable base 21 and is connected to the driving motor 23 by driving. The wire lifting clamp is provided with the guide placement cavity, and the remote control structure is connected with the driving motor 23 by electrical signals to control the driving motor 23 to drive the telescopic body 22 to lift or lower the wire. Specifically, the telescopic body 22 is composed of a first rod body 221 and a second rod body 222. The first rod body 221 is sleeved on the circumference of the second rod body 222. The driving motor 23 is connected to the second rod body 222 by driving, so that the second rod body 222 extends or retracts the first rod body 221. The driving motor 23 is a forward and reverse motor to lift or lower the wire, thereby improving the lifting stability, work efficiency and work safety.

[0033] In an optional embodiment, if Figure 1 As shown, the movable base 21 includes two mounting blocks, which are arranged opposite to each other and form the slide groove, and the two mounting blocks are closed and clamped to install the support rod 3 through a quick-locking bolt 211. Specifically, a gap is formed between the two mounting blocks to facilitate the installation of the support rod 3. After the lifting assembly 2 is moved to a desired position along the length direction of the support rod 3, the quick-locking bolt 211 is used to close and clamp the support rod 3 to prevent the lifting assembly 2 from shifting and improve the lifting stability of the lifting assembly 2.

[0034] In an optional embodiment, if Figure 3 and Figure 4 As shown, the wire lifting clamp includes a clamp body 24 and a V-shaped self-locking member 25. A U-shaped groove 242 is provided on one side of the clamp body 24, and a limiting groove 243 is provided on the other end. One end of the V-shaped self-locking member 25 is protruding from the clamp body 24, and the other end is abutted against the groove wall of the limiting groove 243. The V-shaped self-locking member 25 is movably connected to the U-shaped groove 242 through a rotating shaft, and the V-shaped self-locking member 25 is located to rotate around the rotating shaft to open or close the opening of the guide placement cavity. Specifically, the weight of one end of the V-shaped self-locking member 25 protruding from the clamp body 24 is greater than the other end of the V-shaped self-locking member 25, so that after the V-shaped self-locking member 25 is pushed away and enters the guide placement cavity during the wire lifting process, the V-shaped self-locking member 25 can automatically return to its original position, and the design of the limiting groove 243 can limit the rotation range of the V-shaped self-locking member 25.

[0035] In an optional embodiment, if Figure 4As shown, the part of the V-shaped self-locking member 25 protruding from the clamp body 24 is provided with a hanging hole 251 for connecting the unlocking rod to open the opening of the guide placement cavity. Specifically, when the worker needs to take out the wire after completing the live work, the worker cannot touch the wire, so the worker is at a certain distance from the wire. The unlocking rod is hung on the hanging hole 251 and the part of the V-shaped self-locking member 25 protruding from the clamp body 24 is pushed, so that the V-shaped self-locking member 25 rotates around the rotation axis, and the other part of the V-shaped self-locking member 25 rotates toward the direction of the U-shaped groove 242, so that the opening of the guide placement cavity is opened, and the wire is separated from the guide placement cavity during the process of lowering the lifting assembly 2.

[0036] In an optional embodiment, if Figure 1 and Figure 2 As shown, the clamping assembly 1 includes a clamping base 11, a connecting rod 12 and a clamping block 13. The clamping base 11 has an active cavity 111. One end of the connecting rod 12 is movably inserted into one end of the active cavity 111 and is connected to the clamping block 13. A locking crank 14 is provided at the other end. The clamping block 13 is driven to move along the length direction of the clamping base 11 by the locking crank 14 and the connecting rod 12, and is enclosed with the cavity wall of the active cavity 111 on the opposite side to form a clamping space 15 to clamp the cross arm 4. Specifically, a threaded groove 112 is provided at one end of the clamping base 11, and the connecting rod 12 is threadedly connected to the threaded groove 112. A bearing is provided between the connecting rod 12 and the clamping block 13. The staff drives the connecting rod 12 to rotate by rotating the locking crank 14, and drives the clamping block 13 to move in the direction close to or away from the other end of the clamping base 11 through the bearing, thereby achieving the purpose of adjusting the size of the clamping space 15, thereby making it convenient for the staff to install the clamping assembly 1 on the cross arm 4.

[0037] In an optional embodiment, if Figure 2 As shown, a connection piece 5 is provided on the surface of the clamping base 11 away from the active cavity 111, and the connection piece 5 is provided with a mounting groove 51, and the mounting groove 51 is used to install the support rod 3. Specifically, the arrangement of the connection piece 5 facilitates the installation of the support rod 3, and the mounting groove 51 is a through structure, and one end of the support rod 3 passes through two connection pieces 5 in sequence, and a sealing ring is provided on the groove wall of the mounting groove 51, which can prevent the support rod 3 from rotating and improve the installation stability of the lifting assembly 2; further, the clamping base 11 and the connection piece 5 can be a powder structure or an integrally formed structure. In this embodiment, the clamping base 11 and the connection piece 5 are a split structure.

[0038] In an optional embodiment, if Figure 2As shown, the surface of the connector 5 facing the clamping base 11 is provided with a groove 52, and the connector 5 is tightly mounted with the clamping base 11 through the groove 52. Specifically, the groove 52 and the clamping base 11 cooperate with each other to improve the connection strength between the two, ensuring that the lifting assembly 2 is stably lifted or lowered during the process of lifting the wire, and the clamping base 11 and the connector 5 are detachably connected by screws, which is convenient for disassembly and storage, replacement of components, etc., and reduces the storage space.

[0039] In an optional embodiment, two support rods 3 are provided, and two mounting grooves 51 are correspondingly provided. Specifically, the two support rods 3 are arranged in parallel, and the movable base 21 also has two slide grooves. After the two support rods 3 are respectively inserted into the slide grooves, the two clamping bases 11 are symmetrically installed at both ends of the support rods 3 to provide a stable and sufficient supporting force for the lifting assembly 2; further, the support rods 3 are made of insulating materials, such as insulating plastics such as polyethylene or polyvinyl chloride, which have good insulation properties and can ensure the personal safety of the staff.

[0040] The clamping base 11 of the device can be installed on the same crossarm 4, or between two crossarms 4; the remote control structure includes a remote control and a display screen, and the lifting component 2 also includes a high-definition camera, which is connected to the display screen signal and feeds back the lifting situation to the display screen. The staff controls the lifting height of the wire according to the lifting situation, and the remote control is connected to the drive motor 23 signal. The cooperation of the remote control and the display screen can facilitate the remote operating staff to accurately lift the wire to the required height.

[0041] After the device is assembled on the ground in advance, when it is used, the staff climbs up to install the device to the position where the wire needs to be lifted, such as Figure 6 As shown, the L-shaped cross arm 4 passes through the active cavity 111 of the clamping base 11. At this time, the clamping space 15 is the largest. The rotating locking crank handle 14 drives the clamping block 13 and the clamping base 11 to clamp the cross arm 4, and the wire is placed in the wire lifting clamp. The remote control is remotely controlled to make the drive motor 23 rotate forward and reverse to achieve lifting or lowering of the wire.

[0042] To sum up, the device can be widely used in live replacement of linear rod insulators, replacement of crossarm 4 and other conductor lifting operation scenarios to achieve the lifting and fixation of the conductors and ensure the safety of workers and equipment. The device can be remotely controlled by a remote control structure, and the conductor lifting status can be monitored in real time with a high-definition camera, which is convenient for operators to remotely observe the conductor lifting situation, thereby improving the intelligence level of the bypass operation without power outages in the distribution network, ensuring the safe and reliable operation of the power grid, and having good promotion and application value. The device adopts electric point control technology, and the lifting distance of the overhead conductor can be flexibly adjusted. The V-shaped self-locking member 25 of the device is suitable for conductors of different wire diameters and has a locking and anti-falling function.
