Description

Technical Field

[0001] This invention relates to the field of spacer technology, and more specifically to a device for installing and removing spacers for curved lines. Background Technology

[0002] With the expansion of my country's power distribution network overhead lines and technological upgrades, the unit length mass of conductors, the mass of fittings, and the diameter have increased significantly, leading to a substantial increase in the risk of line galloping. This can cause conductor cross-contact, resulting in serious accidents such as conductor wear, fitting damage, and even line breakage. To prevent cross-contact, spacers are needed to fix the distance between conductors, and drones are used for the rapid hoisting and fixing of spacers.

[0003] However, during the installation process using drones, the drones cannot directly observe the relative positions of the wires and spacers due to the obstruction of the installation components, making it difficult to position the installation on the horizontal plane. Furthermore, the high-voltage lines naturally bend due to gravity, causing the center point of the high-voltage line and the fixing point of the spacers to differ by a certain distance in the vertical direction. This results in the spacers not being able to be accurately installed on the wires, posing a risk of slippage. Additionally, during disassembly, the bending of the wires can make it impossible to position the spacers, preventing the clamps from being disassembled. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the relative positions of the conductor and the spacer cannot be directly observed when using a drone for installation, and the high-voltage line is bent due to gravity in its natural state, making it difficult to position the conductor and the spacer during the installation and disassembly process. The purpose is to design a spacer installation and disassembly device for bent lines to solve the above-mentioned technical problems.

[0005] The present invention provides the following apparatus:

[0006] A device for installing and removing spacer bars for curved wires includes a connector disposed at the end of the spacer bar for connecting to a wire, and the connector bar has a recessed connection port for hanging the spacer bar on the wire installation section.

[0007] The connector is equipped with a positioning component for fixing the wire relative to the connector. The positioning component includes a fixing plate, a segment plate for cutting the wire installation section during installation, and a limiting component for limiting the position. Two segment plates are vertically set at both ends of the fixing plate, and during installation, the two segment plates are set at both ends of the cut wire installation section. The segment plates are aligned with the connection port and have a bayonet on both sides. The bayonet extends to the side to the bottom of the segment plate to form a wire inlet hole. The bayonet extends away from the wire inlet hole to form a movable space, in which the wire can move vertically. The positioning component is coaxially provided with a limiting component on the side of the connector, and the limiting component is recessed with a limiting opening on the side closer to the wire. On the horizontal plane, the bayonet, connection port and / or limiting opening are all located on the same line.

[0008] Furthermore, the connector includes an arc-shaped bracket with a connection port located at the bottom end of the arc-shaped bracket to fit the side of the wire.

[0009] Furthermore, the limiting member is vertically downward below the fixing plate, and the bottom end of the limiting member is recessed with a limiting opening for limiting the alignment of the wire installation section with the connection port.

[0010] Furthermore, a movable plate is movably provided on the side of the positioning component and slides left and right along the axis of the connector; a limiting component is fixedly provided at the bottom of the movable plate; both the front and rear ends of the limiting component are provided with fixing holes that penetrate the upper and lower sides, and fixing bolts are provided in the fixing holes; the bottom of the movable plate is provided with a corresponding fixing hole and a threaded hole, and the threaded section of the fixing bolt passes through the fixing hole and is screwed into the threaded hole for fixation.

[0011] Furthermore, the segment plate is vertically mounted on the side of the fixed plate; adapter blocks are fixedly mounted at both ends of the fixed plate, and threaded holes are provided on the side of the adapter block near the segment plate, with limit bolts screwed into the threaded holes; the segment plate is connected to the adapter block through the limit bolts.

[0012] Furthermore, there are four segment plates, two of which are set as a group and set at the same end of the fixed plate, and two groups of segment plates are set at both ends of the fixed plate respectively; the two segment plates in the same group are rotatably set at one end of the fixed plate along the axis of the limiting bolt. The latches at the bottom of the two segment plates are rotated inward and brought closer to each other until the two latches are aligned with each other. At this time, the two latches are aligned with the connection port.

[0013] Furthermore, a gap is provided between the head of the limiting bolt and the side of the adapter block; a rotating hole is provided on the top of the segment plate, and the segment plate is fitted into the gap through the rotating hole; the adapter block of the fixing plate has two horizontal rotating holes corresponding to the two segment plates in the same group, and the two segment plates are respectively fitted onto the corresponding limiting bolts through the rotating holes.

[0014] Furthermore, a sliding joint for connection is provided between the two segment plates; both segment plates are provided with straight sliding strip holes, and the two ends of the sliding joint pass through the sliding strip holes respectively, and the sliding joint moves along the sliding strip holes.

[0015] Furthermore, the middle part of the segment plate has a hollow structure as a lightweighting measure to reduce the overall weight of the device.

[0016] Furthermore, the bottom of the segment plate is provided with guide slopes at both ends of the bayonet. The guide slopes extend obliquely from the bottom of the segment plate toward the bayonet at the top, so that the wire is always guided into the bayonet for limiting connection.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. This invention enables the installation of conductors that sag due to gravity. The conductor installation section is cut out using segment plates at both ends, and then the control device moves further downwards. At this point, the conductor within the bayonet is fixed to the segment plate, allowing the limiting components at both ends to contact the sagding conductor through the limiting ports. Since the limiting ports and the connecting ports are on the same horizontal line, the connecting components and the sagding conductor can contact and fit together. This completes the positioning process of the spacer bar for the curved conductor, thus solving the problems of difficult positioning, alignment, and disassembly between two conductors.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example 1:

[0028] Reference Figure 1 and Figure 2 A device for installing and removing spacer bars 1 for curved wires includes a connector 2 for fixing the spacer bar 1 to the conductor. The connector 2 is the core load-bearing component for achieving a stable connection between the spacer bar 1 and the conductor. It is fixedly connected to the end of the spacer bar 1. The connection method can be a rigid connection such as welding or bolt fastening to ensure that no relative displacement occurs during installation, disassembly and long-term use. The connector 2 has a recessed connection port 3 for hanging the spacer bar 1 on the conductor installation section. The shape of the connection port 3 is adapted to the cross-sectional contour of the conductor. It is usually an arc-shaped recessed structure. Its curvature is designed according to the diameter specifications of common conductors to ensure that the conductor can fit tightly against the inner wall of the connection port 3 to achieve initial positioning and load bearing.

[0029] The connector 2 is equipped with a positioning component 4 for adjusting the wire to be parallel to the connector 3. The positioning component 4 includes a fixing plate 5, a segment plate 6 for cutting the wire installation section during installation, and a limiting component 7. The whole assembly is mounted on the fixing plate 5 and maintains a relatively fixed position with the connector 2. The two segment plates 6 are respectively vertically set at both ends of the fixing plate 5. The vertical setting can ensure that the segment plates 6 fix the wire in the vertical direction. During installation, the two segment plates 6 are correspondingly set at both ends of the wire installation section. Through the joint action of the segment plates 6 at both ends, a specific length of wire installation section is cut out from the overall extension direction of the wire, avoiding interference with the positioning accuracy caused by the bending state of other non-installation sections of the wire.

[0030] The segment plate 6 is aligned with the connection port 3 and has bayonets 8 on both sides. The opening direction of the bayonets 8 is consistent with the extension direction of the connection port 3, and the internal contour is adapted to the shape of the wire to ensure that the wire can be stably inserted. The bayonets 8 extend to the side to the bottom of the segment plate 6 to form a wire inlet hole 9. The width of the wire inlet hole 9 is slightly larger than the diameter of the wire, and it extends downward in an open shape to provide a guide channel for the wire to enter the bayonets 8, so that the wire can slide smoothly into the wire inlet hole 9 and finally enter the bayonets 8 during the device lowering process. The bayonets 8 extend to the side away from the wire inlet hole 9 to form an active space. The height of the active space is designed according to the possible bending and sag of the wire. The wire can move vertically in the active space to allow the wire to have a certain vertical displacement in the initial positioning stage, and to reserve adjustment margin for subsequent precise correction by the limiting member 7.

[0031] The positioning component 4 is coaxially provided with a limiting component 7 on the side of the connector 2. The coaxial arrangement means that the central axis of the limiting component 7 is on the same straight line as the central axis of the connector 2. The limiting component 7 is recessed with a limiting opening 11 on the side near the wire. The limiting opening 11 is semi-circular in shape, and its curvature is consistent with the curvature of the connector 3 and the bayonet 8, ensuring that the wire can simultaneously fit against the inner walls of the three. The bayonet 8, the limiting opening 11, and the connector 3 are on the same horizontal axis. When the wire is simultaneously inserted into the bayonet 8 and the limiting opening 11 and fits against the connector 3, the horizontal axes of the three coincide, which can forcibly adjust the originally bent and drooping wire installation section to be aligned with the connector. The parallel state completely solves the positioning deviation problem caused by the bending of the wire. During the disassembly process, the device is lowered to the vicinity of the wire by a drone or other hoisting equipment. The wire enters the bayonet 8 of the segment plate 6 through the wire inlet hole 9. At this time, the wire can maintain a natural bending state in the movable space. Then the device continues to move downward, and the limiting member 7 gradually approaches the wire until the wire is locked into the limiting port 11. Since the bayonet 8, the limiting port 11, and the connecting port 3 are coaxial, the wire is forced to be adjusted to a horizontal state on the same line under the joint constraint of the three. The subsequent disassembly process can make the positioning component 4 aligned with the connecting member 2. Finally, the connecting member 2 is separated from the wire, and then the spacer 1 is removed.

[0032] Specifically, connector 2 includes an arc-shaped bracket 12. The overall structure of the arc-shaped bracket 12 is semi-circular or slightly curved. Its curvature is precisely designed according to the outer circle contour of the conductor, ensuring that the inner wall of the arc-shaped bracket 12 can fit against the outer surface of the conductor over a large area, improving the stability and load-bearing capacity of the connection. Connecting port 3 is located at the bottom of the arc-shaped bracket 12. The arc shape of the connecting port 3 is consistent with the overall arc shape of the arc-shaped bracket 12, forming a continuous concave structure to fit the side of the conductor. The setting of the arc-shaped bracket 12 changes the contact method between connector 2 and conductor from point contact or line contact to surface contact, effectively dispersing the pressure on the conductor and avoiding conductor wear due to local stress concentration during long-term use. At the same time, the surface contact structure can improve the stability of the connection and prevent the spacer 1 from slipping under the action of external forces such as wind and line vibration. During installation, when the conductor is adjusted by the positioning component 4 to be parallel to the connecting port 3, the connecting port 3 at the bottom of the arc-shaped bracket 12 can tightly wrap the side of the conductor, forming a stable load-bearing structure.

[0033] Specifically, the limiting member 7 is vertically downwardly positioned below the fixing plate 5. This vertical downward installation direction ensures that the limiting opening 11 of the limiting member 7 can form a precise vertical correspondence with the wire below, preventing poor contact or positioning deviation caused by the limiting member 7 being tilted. The bottom end of the limiting member 7 is recessed and has a limiting opening 11 for aligning the wire installation section with the connection port 3. The position of the limiting opening 11 is fixed relative to the fixing plate 5, and its opening direction is horizontally towards the wire installation section, consistent with the orientation of the connection port 3. Through its vertical downward layout, the limiting member 7 can gradually approach the wire from above during the device's lowering process. When the wire enters the locking slot… After step 8, the limiting member 7 continues to move downward until the inner wall of the limiting port 11 contacts the outer surface of the wire. Since the limiting port 11 and the connecting port 3 are coaxial, the wire can no longer deviate in the horizontal direction under the constraint of the limiting port 11. It can only adjust its position in the vertical direction within the movable space, and finally achieve the alignment and positioning of the wire installation section and the connecting port 3. The structure of the limiting port 11 at the bottom of the limiting member 7 allows the limiting effect to be directly applied to the installation section of the wire, avoiding interference with the non-installation section of the wire. At the same time, the position design of the bottom end can shorten the distance between the limiting member 7 and the wire, improve the positioning response speed, and ensure that the limiting alignment of the wire can be completed quickly during the lowering of the device.

[0034] Specifically, a movable plate is movably mounted on the side of the positioning component 2, and the movable plate slides left and right along the axis of the connecting component 2; a limiting component 7 is fixedly mounted on the bottom of the movable plate; both the front and rear ends of the limiting component 7 are provided with fixing holes 13 penetrating the upper and lower sides, and fixing bolts 14 are installed in the fixing holes 13. The fixing bolts 14 are standard threaded bolts, and their length is determined according to the sum of the thickness of the limiting component 7 and the thickness of the fixing plate 5, ensuring that the threaded section is screwed into the threaded hole at the bottom of the movable plate; the bottom of the movable plate is provided with threaded holes corresponding to the fixing holes 13. The threaded section of the fixing bolt 14 passes through the fixing hole 13 and is screwed into the threaded hole for fixation. The inner diameter and pitch of the threaded hole are perfectly matched with the threaded section of the fixing bolt 14. A rigid connection is made using a bolt connection structure. The limiting member 7 is fastened to the movable plate in the vertical direction through the fixing bolt 14. The limiting member 7 is movably set below the fixed plate 5 through the movable plate to ensure that the position between the limiting member 7 and the fixed plate 5 always remains coaxial, avoiding the limiting member 7 from shifting due to external force during the positioning process, thereby ensuring the coaxiality of the limiting port 11 and the connecting port 3.

[0035] Preferably, the segment plate 6 is vertically disposed on the side of the fixed plate 5. This vertical arrangement ensures that the length of the segment plate 6 extends vertically, allowing the wire inlet hole 9 to extend upwards from the bottom to the bayonet 8, providing a smooth path for the wire. Adapter blocks 16 are fixedly disposed at both ends of the fixed plate 5, and are connected to the fixed plate 5 by screws, ensuring a rigid connection between the two. The adapter blocks 16 provide a transition structure for the connection between the segment plate 6 and the fixed plate 5, avoiding the impact on the structural strength of the fixed plate 5 caused by directly machining threaded holes on it. A threaded hole is provided on the side of the adapter block 16 near the segment plate 6. The threaded hole is horizontally opened, with its axis perpendicular to the side of the segment plate 6. The specifications of the threaded hole match the threaded section of the limit bolt 15. A screw thread is then threaded into the threaded hole. A limiting bolt 15 is connected, with its threaded section screwed into the threaded hole of the adapter block 16. The head of the limiting bolt 15 is located on the side away from the adapter block 16, opposite to the side of the segment plate 6. The segment plate 6 is connected to the adapter block 16 via the limiting bolt 15. Specifically, the segment plate 6 is fitted between the threaded section and the head of the limiting bolt 15, and the head of the limiting bolt 15 provides axial restraint to the segment plate 6, preventing it from falling off. The adapter block 16 is fixed to both ends of the fixing plate 5, and the limiting bolt 15 is horizontally screwed onto the adapter block 16. The segment plate 6 is vertically positioned between the adapter block 16 and the head of the limiting bolt 15, achieving axial fixation through the limiting bolt 15. This provides a stable installation base for the segment plate 6 and a support point for its rotational movement.

[0036] Reference Figure 3 and Figure 4In some embodiments, the segment plate 6 can rotate around the axis of the limiting bolt 15 to open and close the bayonet 8, facilitating the entry and positioning of the wire. The screwed structure of the limiting bolt 15 ensures that the segment plate 6 can rotate flexibly and prevents the segment plate 6 from rotating on its own due to vibration during the positioning process. Preferably, four segment plates 6 are provided, and the four segment plates 6 have completely identical structural dimensions. Two segment plates 6 are combined as a group and set at the same end of the fixed plate 5, and two groups of segment plates 6 are respectively set at both ends of the fixed plate 5. A set of segment plates 6 is provided on the left end of the fixing plate 5, and another set of segment plates 6 is provided on the right end. The two segment plates 6 in the same set are rotatably mounted on one end of the fixing plate 5 along the axis of the limiting bolt 15. The rotation axis allows the two segment plates 6 to rotate towards or away from each other about the axis of the limiting bolt 15, thereby opening and closing the two latches 8. The latches 8 at the bottom of the two segment plates 6 are brought closer together by rotating inward until the two latches 8 are aligned. At this time, the two latches 8 are aligned with the connecting port 3, forming a connection. The positioning channel consists of two segment plates 6 symmetrically distributed on both sides of the limiting bolt 15 at the same end. The top of each segment plate 6 is fitted onto the limiting bolt 15, and the bottom extends downwards. The locking slots 8 are located on opposite inner sides of the bottom end. By rotating the two segment plates 6 in opposite directions, the two locking slots 8 are closed, constraining both sides of the wire and improving positioning stability, preventing the wire from slipping off one side of a single locking slot 8. During operation, before installation, the two segment plates 6 in the same group are in a reverse rotation state, and the locking slots 8 are separated, allowing the wire to enter through the hole. 9 is in the open state; when the device is lowered to the wire position, the wire enters between the two segment plates 6 through the wire inlet hole 9, and then the wire abuts against the inner side of the wire inlet hole 9 of the segment plate 6. The wire moves upward relative to the segment plate 6, causing the two segment plates 6 to rotate inward until the two bayonets 8 are aligned with each other. At this time, the wire is locked into the two aligned bayonets 8, forming a double-sided limit; since the two bayonets 8 are aligned with the connection port 3, the wire can be accurately aligned with the connection port 3 under the constraint of the bayonets 8, providing a basis for the subsequent positioning of the limit component 7.

[0037] Reference Figure 3Specifically, the segment plate 6 is rotatably mounted on the side of the fixed plate 5, and the rotatable connection is achieved through the cooperation of the limiting bolt 15 and the adapter block 16. A gap is provided between the head of the limiting bolt 15 and the side of the adapter block 16. The width of this gap is slightly larger than the thickness of the segment plate 6, ensuring that the segment plate 6 can rotate flexibly within the gap without jamming or excessive shaking. A rotating hole 17 is provided on the top of the segment plate 6. The rotating hole 17 is a circular through hole, and its inner diameter is slightly larger than the diameter of the threaded section of the limiting bolt 15, ensuring that the segment plate 6 can be fitted into the gap through the rotating hole 17. Furthermore, the rotating hole 17 and the limiting bolt 15 are clearance-fitted to reduce friction between the segment plate 6 and the side of the transition block 16 during rotation; a shim with the same thickness as the segment plate 6 is fitted into the clearance at one end to prevent the two segment plates 6 from coming into contact and getting stuck when rotating relative to each other; the transition block 16 of the fixing plate 5 has two horizontally formed rotating holes 17 corresponding to the two segment plates 6 in the same group. The axes of the two rotating holes 17 coincide with the axis of the limiting bolt 15, and the spacing between the two rotating holes 17 matches the spacing between the two segment plates 6 in the same group. The two segment plates 6 are respectively connected through... The rotating hole 17 is fitted onto the corresponding limiting bolt 15; the two rotating holes 17 on the adapter block 16 are horizontally coaxially arranged, and the limiting bolt 15 passes through the two rotating holes 17 and is screwed into the threaded hole of the adapter block 16. The two segment plates 6 are respectively fitted onto the two threaded sections of the limiting bolt 15, located in the gap between the adapter block 16 and the head of the limiting bolt 15; providing independent and coaxial rotational support for the two segment plates 6 in the same group, ensuring that the two segment plates 6 can rotate synchronously, and that the locking jaws 8 approach each other until they are aligned during rotation; during installation, when it is necessary to adjust the segment plates At angle 6, the two segment plates 6 can rotate independently around the axis of the limiting bolt 15. Since the rotating hole 17 is coaxial with the limiting bolt 15, the rotation trajectory of the two segment plates 6 is consistent, which can accurately achieve the alignment or separation of the bayonet 8. The gap setting not only ensures the rotational freedom of the segment plates 6, but also restricts the axial displacement of the segment plates 6 by the shim so that the head of the limiting bolt 15 and the side of the adapter block 16 do not move. This ensures that the segment plates 6 always remain within the preset position range during rotation and will not shift axially, thus avoiding the misalignment of the bayonet 8 caused by the two segment plates 6 abutting against each other.

[0038] Specifically, a sliding joint 19 for linkage is provided on one side of the two segment plates 6 that are close to each other. The sliding joint 19 is a cylindrical or square rigid component, and its length is slightly greater than the sum of the thicknesses of the two segment plates 6, ensuring that it can pass through the sliding strip holes 18 of the two segment plates 6 simultaneously. Each segment plate 6 is provided with a sliding strip hole 18, which is an elongated through hole. Its length extends along the height direction of the segment plate 6, and its width is slightly greater than the diameter or side length of the sliding joint 19, ensuring that the sliding joint 19 can move back and forth along the sliding strip hole 18 without jamming during the movement. The two ends of the sliding joint 19 are respectively inserted into the sliding strip holes 18 of the two segment plates 6, and the sliding joint 19 and the sliding strip hole 18 are clearance fit to reduce frictional resistance during relative movement. The sliding joint 19 is located between the two segment plates 6, with its axis perpendicular to the side of the two segment plates 6, and its two ends are respectively embedded in the sliding strip holes 18 of the two segment plates 6, and can move along the length direction of the sliding strip hole 18. The sliding joint 19 and the sliding bar hole 18 are used to realize the linkage of the two segment plates 6 in the same group, ensuring that the two segment plates 6 can rotate synchronously. During installation, when one segment plate 6 is pushed to rotate around the limit bolt 15, the sliding bar hole 18 on the segment plate 6 will generate a vertical upward thrust on the sliding joint 19. Under the action of the thrust, the sliding joint 19 moves along the sliding bar hole 18 of the other segment plate 6, and at the same time drives the other segment plate 6 to rotate synchronously, finally realizing the alignment of the bayonet 8 of the two segment plates 6 and locking the two ends of the wire. Conversely, when one segment plate 6 is pulled to rotate outward, the other segment plate 6 will also rotate outward synchronously under the linkage of the sliding joint 19, causing the bayonet 8 to separate. The linkage structure of the two segment plates 6 does not require separate control of the movement of the two segment plates 6. It automatically clamps and fixes the wire during the installation process, simplifies the operation process, and ensures the synchronous movement of the two segment plates 6, improving the accuracy and efficiency of the bayonet 8 alignment.

[0039] Reference Figure 1 and Figure 2Specifically, the middle section of segment plate 6 features a hollow structure, which is a through hole penetrating the front and rear sides of segment plate 6. Its shape can be rectangular, circular, or other irregular. The area of ​​the hollow region is designed according to the structural strength requirements of segment plate 6, maximizing the hollow area while ensuring the load-bearing capacity of segment plate 6. The hollow structure is located in the middle section of segment plate 6, avoiding the rotating hole 17 at the top, the bayonet 8 and the lead wire hole 9 at the bottom, and the sliding strip hole 18 on the side, ensuring that it does not affect the connection structure and positioning function of segment plate 6. This reduces the overall weight of the installation device, achieving a lightweight design and reducing the need for drones or other lifting equipment. The lightweight segment plate 6 reduces the load pressure and improves the flexibility and stability of the device during hoisting. During installation, the lightweight segment plate 6 reduces the overall inertia of the device, making it easier for the UAV to adjust the device position and reducing the decrease in positioning accuracy caused by excessive weight. At the same time, the hollow structure does not affect the structural strength of the segment plate 6. Key structures such as the top rotation hole 17 and the bottom latch 8 can still withstand the pressure of the wires and the force during rotation, ensuring that the positioning function of the segment plate 6 is not affected. In addition, the hollow structure can reduce air resistance, making the device less affected by wind in high-altitude environments, further improving the stability of the installation and disassembly process.

[0040] Specifically, the bottom of the segment plate 6, corresponding to the left and right ends of the bayonet 8, is configured with guide ramps 10. The guide ramps 10 are inclined planar structures, extending obliquely from the bottom of the segment plate 6 towards the bayonet 8 at the top. That is, the bottom of the guide ramps 10 opens outwards, and the top converges towards the bayonet 8, forming a trumpet-shaped guide structure. The inclination angle of the guide ramps 10 is designed according to the wire guide requirements, typically between 30 and 60 degrees, ensuring that the wire can smoothly slide along the guide ramps 10 towards the bayonet 8 under the influence of gravity and the downward force of the device. The two guide ramps 10 are located symmetrically on the left and right sides of the bayonet 8, with their bottom ends flush with the bottom of the segment plate 6 and their top ends smoothly transitioning to the edge of the bayonet 8, forming a continuous guide channel for the wire to enter. The bayonet 8 provides a guiding function, ensuring that the wire can accurately and smoothly enter the bayonet 8 during the device's lowering process, avoiding inaccurate or non-adjustable insertion due to wire misalignment. During installation, when the device is lowered near the wire, the wire may be offset from directly below the bayonet 8 due to bending, wind, or other factors. In this case, the guide ramp 10 at the bottom of the segment plate 6 will first contact the wire. Due to the inclined structure of the guide ramp 10, the wire will be subjected to a lateral force from the guide ramp 10 as the device continues to lower. This force guides the wire towards the bayonet 8, causing it to gradually slide along the guide ramp 10 towards the bayonet 8. When the wire reaches the top of the guide ramp 10, it will smoothly enter the bayonet 8, completing the initial positioning of the wire. The guide ramp 10 improves the error tolerance of wire insertion. Even if the initial position of the wire has a certain deviation, it can accurately enter the bayonet 8 through the guiding function, improving the efficiency of the installation process.

[0041] Reference Figure 1 and Figure 2 The installation process of the above-mentioned device is as follows: First, when installing the spacer bar 1 of the curved line, the assembly preparation of the device is carried out by assembling each structure according to the preset connection relationship; the connector 2 is fixedly connected to the end of the spacer bar 1 by welding or bolt fastening to ensure that there is no relative displacement between the two; the adapter block 16 is fixed to both ends of the fixing plate 5, so that the threaded hole of the adapter block 16 is horizontally facing outward; the limiting bolt 15 is screwed into the threaded hole of the adapter block 16, and a gap is reserved between the head of the limiting bolt 15 and the side of the adapter block 16, the width of which is adapted to the thickness of the segment plate 6; the segment plate 6 is fixed to the adapter block 16 by the corresponding limiting bolt 15, and the device preparation before installation is completed.

[0042] The second step is to use a drone or other hoisting equipment to lift the device and spacer 1 together, adjust the position of the hoisting equipment, and slowly bring the device close to the preset wire installation position. When the device is lowered above the wire, adjust the horizontal position of the device so that the wire is located in the area directly below the wire inlet hole 9 at the bottom of the segment plate 6.

[0043] The third step involves continuing to control the lowering device of the hoisting equipment, gradually bringing the conductor closer to the bottom of the segment plate 6. When the conductor contacts the guide ramp 10 at the bottom of the segment plate 6, due to the downward force generated by the continuous lowering of the device, the conductor slides towards the bayonet 8 under the guidance of the guide ramp 10. The guide ramp 10 generates a lateral guiding force on the conductor through its inclined structure. Even if there is a slight deviation in the initial position of the conductor, it can gradually approach the bayonet 8 along the guide ramp 10 under the action of this guiding force. As the device continues to lower, the conductor slides to the top of the guide ramp 10 and smoothly enters the bayonet 8 of the segment plate 6, completing the initial introduction of the conductor. At this time, the conductor is located in the bayonet 8 and can move vertically in the activity space formed by the extension of the bayonet 8 away from the inlet hole 9. Since the conductor is in a natural curved state, it will droop in the activity space. The segment plates 6 at both ends work together through the bayonet 8 to cut out a specific length of conductor installation section.

[0044] The fourth step involves continuing to control the lowering device of the hoisting equipment. Since the conductor is fixed by the latches 8 of the segment plate 6, the downward movement of the device will cause the limiting component 7 to move downwards synchronously, gradually approaching the conductor installation section. When the limiting port 11 of the limiting component 7 contacts the conductor, because the limiting port 11, the connecting port 3, and the latches 8 are on the same horizontal axis, the conductor, constrained by the limiting port 11, can no longer hang freely in the vertical direction and can only be gradually adjusted to a horizontal state within the movement space. As the device is further lowered, the conductor is forced to be parallel to the connecting port 3 under the combined constraint of the latches 8 and the limiting port 11. At this time, the connecting port 3 of the connector 2 is tightly fitted to the outer surface of the conductor, completing the precise positioning of the spacer 1 and the conductor.

[0045] Finally, the connector 2 is fastened to the wire by the pre-set fixing structure of the connector 2, ensuring that the spacer 1 can be stably fixed on the wire, completing the entire installation process. During the fixing process, since the wire has been accurately positioned, the fixing structure can smoothly act on the contact part between the connector 3 and the wire, avoiding fixing failure due to positioning deviation.

[0046] The process of disassembling spacer 1 is as follows:

[0047] The first step is to connect the dismantling tools to the device using hoisting equipment, or to directly use a drone to move the entire device close to the installation position of the spacer bar 1. Adjust the position of the device so that the segment plates 6 at both ends are located at the two ends of the wire installation section. Move it further downward so that the wire enters the bayonet 8 through the wire inlet hole 9. Secure the wire through the bayonet 8 and initially position the wire section of the dismantling device.

[0048] The second step is to further lower the device and adjust it to be parallel to the connection port 3 to ensure that the relative position of the connector 2 and the wire is fixed, so as to avoid the wire shifting during disassembly and causing disassembly difficulties.

[0049] The third step is to unlock the fixing structure of connector 2 and disconnect connector 2 from the wire.

[0050] The fourth step involves using hoisting equipment or a drone to lift the device upwards, completely separating the connector 2 from the wire, and simultaneously releasing the wire from the constraint of the clamp 8, until the spacer 1 is lifted from its original position and returned to the ground, completing the disassembly process.

[0051] Throughout the installation and disassembly process, the positioning component 4 cuts the wire installation section through the slot 8 of the segment plate 6, and improves the accuracy of wire insertion through the guide slope 10. The limiting port 11 of the limiting component 7 adjusts the bent wire to a state parallel to the connection port 3 during installation. The connecting component 2 achieves precise fitting and fixation with the wire through the connection port 3 of the arc-shaped hanger 12. The positional relationship, connection structure and operation process of each structure are closely coordinated, effectively solving the positioning problem of the spacer 1 during installation and disassembly in the bent wire state, and improving the efficiency and reliability of installation and disassembly.
