Description

Technical Field

[0001] This invention relates to the field of overhead ground wire lifting technology, and in particular to an overhead ground wire lifting structure and method. Background Technology

[0002] An overhead ground wire, also known as a lightning protection wire, refers to a conductor directly connected to the ground on high-voltage and ultra-high-voltage power lines. Due to the shielding effect of the overhead ground wire on the conductor and the coupling effect between the conductor and the overhead ground wire, the chance of lightning striking the conductor directly is reduced. When lightning strikes a tower, a portion of the lightning current can be diverted through the overhead ground wire, thereby lowering the tower top potential and improving the lightning withstand level. During the installation of overhead ground wires, a lifting structure is used to assist workers in the process. This structure allows the overhead ground wire to be hoisted and adjusted to the required position during installation, greatly increasing the convenience and efficiency of the operation while also enhancing safety. It solves the problems of low efficiency, difficulty in applying force, and high risk associated with manual lifting, providing effective protection for worker safety.

[0003] A search revealed Chinese patent application number 201410324818.9, which discloses an overhead ground wire lifting device. The device features a spool on a stranded wire reel, a spool wrench connected to the spool, a rope wound around the spool, and a lifting hook at the rope's lead-out end. One end of a telescopic rod is movably connected to the stranded wire reel, and the other end of the telescopic rod is connected to a locking seat with an adjustment mechanism. The overhead ground wire lifting device in this patent has the following shortcomings: It lacks an effective adjustment and fixing device at the fixed point, making it impossible to adapt to the width of the power tower installation location during installation. This can lead to problems where the installation location is too wide to be properly secured, severely impacting normal use and installation efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution: An overhead ground wire lifting structure includes a fixing component. The fixing component includes a fixing frame. A spring is arranged on the inner wall of one side of the fixing frame, with several groups of springs arranged sequentially. A first mounting seat is installed at one end of each spring, through which a connecting shaft is rotatably mounted. Several groups of connecting shafts are arranged sequentially, and movable wheels are mounted on the connecting shafts.

One end of the guide rod is fixed to the first mounting seat, and the diameter of the guide rod end is larger than the diameter of the guide hole. An electric telescopic cylinder is installed on one side of the fixing frame, and the telescopic end of the electric telescopic cylinder is slidably mounted. The device features a fixed frame with a second mounting base at the end of an electric telescopic cylinder. A motor compartment is mounted on top of the second mounting base, and a drive shaft is connected to the output end of the motor compartment. Several sets of drive shafts are arranged sequentially, with one end of each drive shaft rotatably passing through the second mounting base. A drive wheel is mounted on the drive shaft. Several sets of limiting holes are provided on one side of the fixed frame, through which a limiting rod is slidably mounted. One end of the limiting rod is fixed to the second mounting base, and a limiting block is provided at the end of the limiting rod. The diameter of the limiting block is larger than the diameter of the limiting hole. A connecting frame is mounted on one side of the fixed frame, and a lifting assembly for lifting the line is provided on one side of the connecting frame.

[0005] As a further embodiment of the present invention: the lifting component includes a fixing plate, which is installed at the bottom of the connecting frame. A winding motor is installed on one side of the fixing plate, and an installation shaft is connected to the output end of the winding motor. One end of the installation shaft is rotatably disposed through the fixing plate. A winch is installed on the installation shaft, and a connecting cable is wound up by the winch. A protective cover is provided on one side of the fixing plate. The size and position of the protective cover are adapted to the winch. An opening is provided at the bottom of the protective cover. The position and size of the opening are adapted to the connecting cable. A connecting component for fixing the overhead ground wire is provided at one end of the connecting cable.

[0006] As a further embodiment of the present invention: the connecting component includes a support plate, which is installed at the end of the connecting cable. A fixing seat is provided at the bottom of the support plate. Two sets of fixing seats are arranged in parallel. A clamp is rotatably installed through the fixing seat. The clamp is a left and right split design. A wear-resistant pad is provided on the inner wall of the clamp. A limiting component for limiting the position is provided on one side of the clamp.

[0007] As a further embodiment of the present invention: the limiting component includes a fixing pin, the fixing pin being U-shaped, the fixing pin having a screw hole, through which a fixing bolt can be detachably installed, and two sets of positioning holes being provided on one side of the clamp, the fixing pin being detachably installed at the positioning holes of the clamp.

[0008] As a further embodiment of the present invention: a power compartment is provided on one side of the fixed plate, a cover plate is detachably provided on one side of the power compartment, a solar charging panel is provided on one side of the power compartment, and two sets of solar charging panels are arranged in sequence.

[0009] As a further embodiment of the present invention: a hanging ring is installed on the top of the fixing frame, and several sets of hanging rings are arranged in sequence.

[0010] As a further embodiment of the present invention: a support frame is provided at one end of the connecting cable, and the bottom end of the support frame is fixed to the support plate.

[0011] As a further embodiment of the present invention: a reinforcing beam is provided on one side of the fixing frame, and several sets of reinforcing beams are arranged in sequence. The other end of the reinforcing beam is fixed to the connecting frame, and a reinforcing rib is provided on one side of the reinforcing beam.

[0012] As a further aspect of the present invention: a grounding bar is provided on the top of the fixing frame, and the grounding bar is made of aluminum.

[0013] A method for lifting overhead ground wires, applied to an overhead ground wire lifting structure as described in any of the foregoing technical solutions, includes the following steps: S1: Align the mounting bracket with the fixed position on the power tower and snap it in. After snapping in, the movement of the second mounting base can be controlled by the electric telescopic cylinder. The movement of the second mounting base and the cooperation of the moving wheels can complete the pressure fixation. After fixation, the installation is complete. When the position needs to be adjusted after installation, the motor in the motor compartment can be started to control the rotation of the drive shaft and drive wheel. The drive wheel can be rotated to fit the fixed position on the power tower for convenient displacement. During fixation, the spring can play a buffer protection role. The guide rod and limit rod can guide to ensure that the movement trajectory will not deviate. After fixation, the grounding wire is connected through the grounding busbar. Connecting the other end of the grounding wire to the grounding equipment of the power tower can increase safety.

[0014] S2: After installation, the fixing bolts can be removed and the fixing pins pulled out, allowing the clamps to rotate and separate. After separation, the overhead ground wire can be moved to the clamp. After movement, the clamps can be reassembled. Once reassembled, the fixing pins can be inserted into the positioning holes of the clamps. After insertion, tightening the fixing bolts onto the fixing pins completes the limiting fixation, preventing the clamps from separating and causing the overhead ground wire to fall. This completes the connection of the overhead ground wire. After connection, the winch can be rotated by starting the winding motor to wind up or extend the connecting cable. The overhead ground wire can be lifted to the required height for installation as needed. The support frame can be used for reinforcement to prevent the clamps from shifting or falling during lifting.

[0015] As an improvement to the above technical solution, an overhead ground wire lifting structure and method are proposed.

[0016] The beneficial effects of this invention are: 1. By setting up a fixing component, the moving wheels and drive wheels cooperate to hold the power tower at the installation position, which can be easily installed and fixed. The position of the drive wheel can be adjusted according to the width of the power tower fixing position through the electric telescopic cylinder, which can be used to fix the power tower at fixing positions of different widths to complete the fixing installation. This avoids the situation where the width cannot be affected and the fixing cannot be effective, and can ensure normal use. When pressure is applied during the fixing, the spring can buffer the pressure and protect the power tower from deformation caused by excessive pressure, while making the installation and fixing more secure. When the drive wheel moves, the movement trajectory can be restricted by the limit rod sliding in the limit hole of the fixing frame, so as to avoid damage to the electric telescopic cylinder caused by lateral force during movement.

[0017] 2. By setting a fixing pin and fixing bolt, the clamp can be limited and fixed, which can prevent the clamp from accidentally opening during the lifting process and causing the overhead ground wire to fall, thus increasing the safety of lifting the line.

[0018] 3. By using horizontally arranged reinforcing ribs, multiple sets of reinforcing beams can be connected together for reinforcement, which can effectively increase the load-bearing capacity. The connection between the fixed frame and the connecting frame can be reinforced by the reinforcing beams and reinforcing ribs, thereby avoiding the problem of deformation and falling of the connecting frame during use.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example 1

[0022] An overhead ground wire lifting structure, such as Figure 1-8 As shown, the device includes a fixing assembly, which includes a fixing frame 1. A spring 30 is arranged on the inner wall of one side of the fixing frame 1. Several sets of springs 30 are arranged sequentially. A first mounting base 4 is installed at one end of each spring 30. A connecting shaft 29 is rotatably mounted through the first mounting base 4. Several sets of connecting shafts 29 are arranged sequentially. A movable wheel 5 is mounted on the connecting shaft 29. Two sets of guide holes are opened on one side of the fixing frame 1. A guide rod 24 is slidably mounted through the guide holes. One end of the guide rod 24 is fixed to the first mounting base 4. The diameter of the guide rod 24 end is larger than the diameter of the guide hole. An electric telescopic cylinder 22 is installed on one side of the fixing frame 1. The telescopic end of the electric telescopic cylinder 22 slidably passes through the fixing frame 1. The electric telescopic cylinder 22 is equipped with a second mounting base 26 at its end. A motor compartment 25 is mounted on the top of the second mounting base 26. A drive shaft 33 is connected to the output end of the motor compartment 25. Several sets of drive shafts 33 are arranged in sequence. One end of the drive shaft 33 can rotatably pass through the second mounting base 26. A drive wheel 27 is mounted on the drive shaft 33. Several sets of limiting holes are opened on one side of the fixed frame 1. Limiting rods 21 are slidably installed through the limiting holes. One end of the limiting rod 21 is fixed to the second mounting base 26. A limiting block is provided at the end of the limiting rod 21. The diameter of the limiting block is larger than the diameter of the limiting hole. A connecting frame 6 is installed on one side of the fixed frame 1. A lifting component for lifting the line is provided on one side of the connecting frame 6. In use, the mounting bracket 1 can be carried up the power tower. The mounting bracket 1 can be aligned with the installation position on the power tower and inserted. After insertion, the electric telescopic cylinder 22 can be activated to control the movement of the second mounting base 26 and the drive wheel 27. By controlling the movement of the drive wheel 27, it is brought into contact with the fixed position on the power tower for pressure fixation. The electric telescopic cylinder 22 can adaptively adjust the position of the drive wheel 27 according to the width of the fixed position on the power tower, adapting to fixed positions of different widths to complete the fixing installation, avoiding situations where width changes prevent effective fixing. When pressure is applied for pressure fixation, the moving wheel 5 contacts the other side of the fixed position on the power tower. The spring 30 provides cushioning during pressure fixation, protecting the power tower from excessive pressure and deformation, while also making the installation more secure. When the first mounting base 4 moves due to the influence of the spring 30, the guide rod 24 slides within the guide hole of the mounting bracket 1 to limit the movement trajectory of the first mounting base 4, preventing deviation during movement. The larger diameter at the end of the guide rod 24 prevents it from detaching from the guide hole. In this configuration, the moving wheel 5 and the drive wheel 27 work together to hold the power tower in place, ensuring a secure installation and connection. After installation, the lifting assembly allows for wire lifting, raising the overhead ground wire to the required height for installation. Once installed, the motor in the motor compartment 25 starts, controlling the drive shaft 33 to rotate. This rotation of the drive shaft 33 synchronously controls the drive wheel 27. The drive wheel 27 rotates in contact with the power tower's fixed position, moving the mounting frame 1 to the fixed position for easy adjustment. This makes the installation more convenient and allows for easy movement to the desired location. The motor in the motor compartment 25 has a self-locking function, preventing unnecessary rotation of the drive wheel 27 and displacement of the mounting frame 1 when the drive stops. When the second mounting base 26 moves, the limit rod 21 slides through the limit hole of the mounting frame 1, restricting the movement trajectory and preventing lateral force from damaging the electric telescopic cylinder 22. The limit block at the end of the limit rod 21 prevents it from dislodging from the limit hole. The lifting assembly includes a fixing plate 23, which is installed at the bottom of the connecting frame 6. A winding motor 17 is installed on one side of the fixing plate 23. An output end of the winding motor 17 is connected to a mounting shaft 32. One end of the mounting shaft 32 is rotatably installed through the fixing plate 23. A winch 31 is installed on the mounting shaft 32. A connecting cable 9 is wound up through the winch 31. A protective cover 8 is provided on one side of the fixing plate 23. The size and position of the protective cover 8 are adapted to the winch 31. An opening is provided at the bottom of the protective cover 8. The position and size of the opening are adapted to the connecting cable 9. A connecting component for fixing the overhead ground wire is provided at one end of the connecting cable 9. During use, the connecting cable 9 can be wound up by the winch 31, and the protective cover 8 can wrap and protect the winch 31 and the wound connecting cable 9 to prevent the winch 31 and the connecting cable 9 from being affected by weathering and aging faster, thus increasing their service life. The forward and reverse rotation of the winding motor 17 can control the synchronous rotation of the installation shaft 32 and the winch 31. The forward and reverse rotation of the winch 31 can control the winding or extension of the connecting cable 9. The overhead ground wire can be fixed by the connecting component. After fixing, the overhead ground wire can be lifted by extending or winding the connecting cable 9, thus facilitating its installation. The connecting assembly includes a support plate 12, which is installed at the end of the connecting cable 9. A fixing seat 10 is provided at the bottom of the support plate 12. Two sets of fixing seats 10 are arranged in parallel. A clamp 11 is rotatably installed through the fixing seat 10. The clamp 11 is a left and right split design. A wear-resistant pad 15 is provided on the inner wall of the clamp 11. A limiting component for limiting is provided on one side of the clamp 11. In use, the left and right semi-rings of the clamp 11 can be controlled to rotate and open to both sides. After opening, the overhead ground wire that needs to be lifted can be moved to the clamp 11. After the movement is completed, the two sets of split left and right semi-rings can be controlled to rotate and merge. After merging, the clamp 11 can be combined into a whole to limit and fix the overhead ground wire, which facilitates the lifting of the overhead ground wire and prevents it from falling during lifting. The limiting component can limit and fix the clamp 11 after it is assembled. The wear-resistant pad 15 can protect the overhead ground wire, thereby preventing the overhead ground wire from being worn and damaged during lifting. The limiting component includes a fixing pin 14, which is U-shaped and has a screw hole. A fixing bolt 13 can be detachably installed through the screw hole. Two sets of positioning holes are provided on one side of the clamp 11. The fixing pin 14 can be detachably installed at the positioning holes of the clamp 11. When in use, after the clamp 11 is assembled, the two ends of the U-shaped fixing pin 14 can be aligned with the positioning holes of the clamp 11 and inserted. After insertion, the fixing bolt 13 can be tightened into the screw hole of the fixing pin 14, thereby completing the limiting and fixing of the clamp 11. This prevents the clamp 11 from accidentally opening during the lifting process, which could cause the overhead ground wire to fall and increase the safety during lifting. For ease of energy supply, such as Figure 3 , 5 As shown, a power compartment 19 is provided on one side of the fixed plate 23, a cover plate 28 is detachably provided on one side of the power compartment 19, a solar charging panel 18 is provided on one side of the power compartment 19, and two sets of solar charging panels 18 are arranged in sequence. When in use, the power compartment 19 is connected to various components of the device through wiring. The cover 28 can be opened to install the battery in the power compartment 19. After installation, it can provide power and maintain the normal operation of various components. When the power is low, the cover 28 can be removed to replace the battery. During use, the battery can receive sunlight through the solar charging panel 18 to supplement power, thereby increasing the range. To facilitate staff carrying and climbing, such as Figure 1 , 2 As shown, a hanging ring 3 is installed on the top of the fixing frame 1, and several sets of hanging rings 3 are arranged in sequence. When in use, a hanging rope can be connected via the hanging ring 3, and the other end of the hanging rope can be hung on the staff, making it easier for the staff to carry and climb, and making it easier to exert force during the climbing process; For reinforcement, such as Figure 2 , 7 As shown in Figures 8 and 9, a support frame 16 is provided at one end of the connecting cable 9, and the bottom end of the support frame 16 is fixed to the support plate 12. During use, the support frame 16 installed on the support plate 12 can reinforce the connection between the support plate 12 and the connecting cable 9, preventing the support plate 12 from falling off when lifting the line, and also preventing the support plate 12 from shifting when lifting the line. To prevent deformation or falling, such as Figure 1 , 4 As shown in Figure 5, a reinforcing beam 7 is provided on one side of the fixed frame 1. Several sets of reinforcing beams 7 are arranged in sequence. The other end of the reinforcing beam 7 is fixed to the connecting frame 6. A reinforcing rib 20 is provided on one side of the reinforcing beam 7. In use, the horizontally arranged reinforcing ribs 20 can connect multiple sets of reinforcing beams 7 together for reinforcement, which can effectively increase the load-bearing capacity. The reinforcing beams 7 and the reinforcing ribs 20 can reinforce the connection between the fixed frame 1 and the connecting frame 6, thereby avoiding the problem of deformation and falling of the connecting frame 6 during use.

[0023] To increase safety, refer to Figure 2 An overhead ground wire lifting structure is provided. Compared with embodiment 1, this embodiment makes the following improvements: a grounding bar 2 is provided on the top of the fixing frame 1, and the grounding bar 2 is made of aluminum. When in use, the grounding busbar 2 made of aluminum can be connected to the connection device after the fixed frame 1 is installed on the power tower, so as to avoid the increase of safety hazards due to conductivity during use. The grounding busbar 2 made of aluminum can reduce weight while ensuring conductivity. Example 2

[0024] To complement Embodiment 1, an overhead ground wire lifting method is provided, applied to an overhead ground wire lifting structure as described in any of Embodiment 1, comprising the following steps: S1: Align the fixing bracket 1 with the fixed position of the power tower and snap it in. After snapping in, the second mounting base 26 can be moved by the electric telescopic cylinder 22. The movement of the second mounting base 26 and the movement wheel 5 can be used to press and fix it. After fixing, the installation is complete. When the position needs to be adjusted after installation, the motor in the motor compartment 25 can be started to control the rotation of the drive shaft 33 and the drive wheel 27. The drive wheel 27 can be rotated in contact with the fixed position of the power tower for convenient displacement. During fixing, the spring 30 can play a buffer protection role. The guide rod 24 and the limit rod 21 can guide the movement to ensure that the movement trajectory will not deviate. After fixing, the grounding wire is connected through the grounding busbar 2. Connecting the other end of the grounding wire to the grounding equipment of the power tower can increase safety.

[0025] S2: After installation, the fixing bolt 13 can be removed and the fixing pin 14 can be pulled out, thereby controlling the clamp 11 to rotate and separate. After rotation and separation, the overhead ground wire can be moved to the clamp 11. After the movement is completed, the clamp 11 can be reassembled. After reassembly, the fixing pin 14 can be inserted into the positioning hole of the clamp 11. After insertion, the fixing bolt 13 can be tightened to the fixing pin 14 to complete the limit fixation and prevent the clamp 11 from separating and causing the overhead ground wire to fall. The connection of the overhead ground wire can be completed. After the connection is completed, the winch 31 can be rotated by starting the winding motor 17 to wind up or extend the connecting cable 9. The overhead ground wire can be lifted to the required height for installation as needed. The support frame 16 can be used for reinforcement to prevent the clamp 11 from shifting or falling during lifting.

9. An overhead ground wire lifting structure according to any one of claims 4 to 8, characterized in that, The top of the fixing frame (1) is provided with a grounding bar (2), which is made of aluminum.

10. A method for lifting an overhead ground wire, applied to an overhead ground wire lifting structure as described in claim 9, characterized in that, Includes the following steps: S1: Align the fixing bracket (1) with the fixed position of the power tower and insert it. After insertion, the second mounting base (26) and the second mounting base (26) can be moved by the electric telescopic cylinder (22). The movement of the second mounting base (26) and the movement wheel (5) can be used to complete the pressure fixing. After fixing, the installation can be completed. When the position needs to be adjusted after installation, the motor in the motor compartment (25) can be started to control the rotation of the transmission shaft (33) and the drive wheel (27). The drive wheel (27) can be rotated in contact with the fixed position of the power tower for convenient displacement. When fixing, the spring (30) can play a buffer protection role. The guide rod (24) and the limit rod (21) can guide the movement to ensure that the movement trajectory will not deviate. After fixing, the grounding wire is connected through the grounding bar (2). Connecting the other end of the grounding wire to the grounding equipment of the power tower can increase safety. S2: After installation, the fixing bolt (13) can be removed and the fixing pin (14) can be pulled out, so that the clamp (11) can be controlled to rotate and separate. After rotation and separation, the overhead ground wire can be moved to the clamp (11). After the movement is completed, the clamp (11) can be combined. After the combination is completed, the fixing pin (14) can be inserted into the positioning hole of the clamp (11). After insertion, the fixing bolt (13) can be tightened to the fixing pin (14) to complete the limit fixation and prevent the clamp (11) from separating and causing the overhead ground wire to fall. The connection of the overhead ground wire can be completed. After the connection is completed, the winch (31) can be started by the winding motor (17) to rotate and the connecting cable (9) can be wound or extended. The overhead ground wire can be lifted to the required height for installation as needed. The support frame (16) can be used to reinforce and prevent the clamp (11) from shifting or falling during lifting.
