Description

Technical Field

[0001] This invention relates to the field of special operation robot technology, and in particular to a tool for installing surge arresters on power distribution networks without power interruption. Background Technology

[0002] In traditional surge arrester installation operations, operators need to use climbing equipment to climb to the crossarm position for construction. Due to the narrow working space at the crossarm and the fact that the surge arrester itself has a certain weight and volume, the on-site installation operation is quite difficult and there are safety risks such as falls from heights. In addition, the electrical connection between the surge arrester and the overhead power line must be completed simultaneously during the installation process, which further increases the complexity and risk of the operation.

[0003] Therefore, it is necessary to propose tools for installing surge arresters on power distribution networks without power interruption to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a tool for installing surge arresters on power distribution networks without power interruption, so as to solve the problems of high difficulty in on-site installation and operation, as well as safety risks such as falls from heights.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a surge arrester installation tool for power distribution networks without power interruption, comprising a working robot, a fixing mechanism, a clamping mechanism, and an installation mechanism, wherein the working robot carries the fixing mechanism, the clamping mechanism, and the installation mechanism to install the surge arrester body; The fixing mechanism includes a chuck and a pressure plate. A rotating component is rotatably mounted on the chuck, and a screw is internally threaded onto the rotating component. The pressure plate is movably mounted at the bottom end of the screw. The clamp mechanism includes a clamp and a lifting eye bolt. The clamp is engaged with the top of the surge arrester body, and the lifting eye bolt is threaded to the bottom of the clamp. The mounting mechanism includes a housing, which is fixed to the execution end of the robot. A drive component is installed inside the housing, and the drive component is connected to the rotating component and the lifting eye bolt. During installation, the claws are detachably installed on the housing, and the bottom of the surge arrester body is positioned on the top of the claws. When the claws are engaged with the crossarm and the clamps are attached to the wire, the drive unit drives the rotating part and the lifting eye bolt to rotate. The pressure plate moves and abuts against the inner corner of the crossarm, and the lifting eye bolt moves upward to cooperate with the clamps to clamp and fix the wire.

[0006] Preferably, a connecting plate is fixedly installed on the side wall of the housing. The connecting plate is L-shaped, and the bottom end of the connecting plate has a limiting part for supporting the bottom end of the surge arrester body. The limiting part is U-shaped. A collar is fixedly installed at the bottom of the limiting part, and there is a gap between the top of the collar and the bottom of the limiting part for the insertion of the claw. An insulating rod is installed at the bottom of the collar and is fixed to the execution end of the working robot.

[0007] Preferably, a bracket is rotatably provided at the top of the collar, a rotating rod is provided above the pawl, the rotating rod is fixed on the bracket, a secondary rack is fixedly connected to the end of the rotating rod away from the bracket, a secondary gear is fixedly connected to the rotating part, and the secondary gear meshes with the secondary rack. The main rack is fixedly connected to one end of the bracket near the housing. One output shaft of the drive unit extends from the bottom of the housing and is fixedly mounted with a main gear. The main rack is meshed with the main gear.

[0008] Preferably, one output shaft of the drive unit extends from the top of the housing and is fixedly mounted with a rotating cylinder, the top of which is provided with a slot for the lifting eye portion of the lifting eye bolt to be inserted.

[0009] Preferably, the housing is provided with a gripping assembly, which includes two gripping arms. The gripping arms are rotatably mounted on the housing via a pin. Both gripping arms are fixedly provided with transmission teeth, and the two transmission teeth are meshed together. A drive motor is fixedly installed on the side wall of the housing, and one of the pins is fixedly connected to the drive shaft of the drive motor.

[0010] Preferably, the pressure plate has sliding channels distributed along its length, the bottom end of the screw passes through the sliding channels and is fixed with a support plate, the support plate abuts against the bottom of the pressure plate, and a guide rod is fixedly installed at the top of the support plate. The guide rod passes through the sliding channels and is slidably mounted on the claw.

[0011] Preferably, a guide frame is fixedly installed on the side wall of the claw, the guide frame is inclined, and the bottom end of the guide frame is inclined away from the crossbeam. A protrusion is slidably arranged inside the guide frame, and the protrusion is fixed to the side of the pressure plate.

[0012] Preferably, a synchronization component is provided on the top of the housing. The synchronization component includes a threaded column, which is slidably disposed on the output shaft of the drive member extending from the top of the housing. Limit seats are hinged on both sides of the top of the threaded column, and a torsion spring is provided at the hinge connection. An insertion channel for the lifting eye bolt to be inserted is formed between the two limit seats. The insertion channel has two switchable states: rectangular and V-shaped; When it is V-shaped, it allows the eye bolt to quickly extend into the slot; When it is rectangular, the two limit seats clamp the eye bolt.

[0013] Preferably, the side of the limiting seat facing away from the threaded column axis is configured from bottom to top as an inclined section, a vertical section and a flange section, and the bottom end of the inclined section is inclined towards the threaded column axis. The threaded column has an external threaded connection to a threaded sleeve, on which a support rod is fixedly installed. The bottom end of the support rod is fixed to the top of the housing, and the top end of the threaded sleeve is fixedly connected to a fixing rod. The top end of the fixing rod is fixedly connected to a ring, which surrounds the outside of the two limiting seats.

[0014] Preferably, the gripper is hinged with a vertical plate that abuts against the lifting eye bolt, the bottom end of the vertical plate is provided with a bent section, a spring is provided between the vertical plate and the gripper, and the ring abuts against the bent section. The outer side of the ring is movably connected to a side rod that abuts against the vertical plate.

[0015] The technical effects and advantages of this invention are as follows: Specialized robot operations eliminate safety risks at heights: By using a work robot in conjunction with a load-bearing work tool, there is no need for operators to climb to heights, thus avoiding safety hazards such as falls from heights and electric shocks at the source; at the same time, it is adapted to automatic alignment and installation in narrow crossarm spaces, reducing the difficulty of manual operation and realizing unmanned and intelligent power distribution network uninterrupted work; Dual-axis linkage drive enables timing synchronization of locking and clamping: A single power source enables the synchronous and coordinated operation of the fixing mechanism and the clamping mechanism, avoiding the shaking and positional displacement of the mechanism caused by step-by-step operation, and ensuring the stability and reliability of high-altitude operations. Quick-connect and quick-disconnect automatic clutch simplifies the installation and disassembly process. The inclined section, vertical section, and flange section of the drive limit seat interact with the ring in sequence to realize the three-stage action of V-shaped opening, vertical clamping, and downward support and lifting of the insertion channel. This enables toolless docking and disengagement between the tool and the clamp mechanism in high-altitude operations, reducing operational complexity. The flexible anti-loosening mechanism is linked to the power unlocking mechanism, ensuring both operational reliability and wire protection. The vertical plate, under the action of the spring, presses the eye bolt of the lifting eye bolt, forming a mechanical friction anti-loosening lock to prevent the lifting eye bolt from loosening due to the swaying and pulling of the wire; at the same time, the side rod limits the vertical plate in a circumferential manner to avoid twisting and squeezing the wire during rotation, effectively reducing damage to the wire; it also realizes automatic unlocking of the same power source, and the anti-loosening and limiting states can be released without additional operation, which not only ensures the connection reliability of the surge arrester in long-term operation, but also improves the continuity of the operation process and the adaptability of flexible wires.

[0034] Example 1, the present invention provides as follows Figures 1-10 The power distribution network uninterrupted installation of surge arresters shown includes a work robot 38 mounted on an aerial lift vehicle 39, which works in conjunction with the aerial lift vehicle 39 to perform special operations.

[0035] In traditional surge arrester installation operations, operators need to use climbing equipment to climb to the crossarm position for construction. Due to the narrow working space at the crossarm and the fact that the surge arrester itself has a certain weight and volume, the on-site installation operation is quite difficult and there are safety risks such as falls from heights. In addition, the electrical connection between the surge arrester and the overhead power line must be completed simultaneously during the installation process, which further increases the complexity and risk of the operation.

[0036] Therefore, the present invention provides a fixing mechanism, a wire clamp mechanism, and an installation mechanism on the control end of the work robot 38; wherein, the fixing mechanism is used to dock and fix with the crossarm 1, the wire clamp mechanism is used to dock and fix with the wire, and the installation mechanism is used to simultaneously support the fixing mechanism and the wire clamp mechanism and complete the installation of the fixing mechanism and the wire clamp mechanism. By using the work robot 38 to carry the fixing mechanism, the wire clamp mechanism, and the installation mechanism, for the special operation of installing surge arresters without power supply to the distribution network, the present invention achieves the goals of unmanned high-altitude operation, integrated installation process, synchronized wiring and locking, and safe operation process.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9As shown, the fixing mechanism includes a pressure plate 15 and a claw 16. The claw 16 has a horizontal part and a vertical part. A fixing post 201 for insertion into the bottom groove of the surge arrester body 2 is fixedly installed at the top of the horizontal part. The pressure plate 15 is located below the horizontal part of the claw 16, and a sliding channel distributed along its length is opened on the pressure plate 15. A rotating member 13 is rotatably arranged on the horizontal part. A screw 12 is axially threaded in the rotating member 13. The horizontal part of the claw 16 has a through hole for the screw 12 to pass through. At the same time, the bottom end of the screw 12 passes through the sliding channel and is fixed with a support plate 24. The support plate 24 abuts against the bottom of the pressure plate 15. At the same time, a guide rod is fixedly installed at the top of the support plate 24. The guide rod passes through the sliding channel, and a through hole for the guide rod to slide is opened on the horizontal part of the claw 16. The guide rod is configured to cooperate with the horizontal part so that the pressure plate 15 will not rotate.

[0038] Reference Figure 3 and Figure 9 As shown, a guide frame 11 is fixedly installed on the side wall of the horizontal part of the claw 16. The guide frame 11 is inclined, and the bottom end of the guide frame 11 is inclined away from the vertical part of the claw 16. A protrusion 1501 is slidably arranged inside the guide frame 11, and the protrusion 1501 is fixedly connected to the side of the pressure plate 15.

[0039] Specifically, the vertical part of the chuck 16 is engaged with the vertical section of the crossarm 1, and the rotating part 13 is controlled to rotate forward. Due to the threaded engagement between the screw 12 and the rotating part 13, and the limiting effect of the guide rod, as well as the guiding effect of the guide frame 11 and the protrusion 1501, the pressure plate 15 moves upward at an angle and abuts against the inner corner of the crossarm 1, thereby locking the pressure plate 15 and the chuck 16 onto the crossarm 1. If the rotating part 13 is controlled to rotate in reverse, the pressure plate 15 moves downward at an angle, releasing the lock. In actual use, the coefficient of friction between the screw 12 and the rotating part 13 is appropriate, which can prevent them from rotating arbitrarily and ensure that the locked state does not loosen.

[0040] Reference Figure 1 , Figure 2 and Figure 5 As shown, the clamp mechanism includes a clamp 3, which is inverted J-shaped. The clamp 3 is connected to the top of the surge arrester body 2 via a lead wire. The bottom end of the side wall of the clamp 3 has a boss 301, and a lifting eye bolt 18 is threaded onto the boss 301. The bottom end of the lifting eye bolt 18 has a lifting eye portion, and the top end of the lifting eye bolt 18 is rotatably connected to a movable clamp 17. The movable clamp 17 fits against the side wall of the clamp 3, and the top end of the movable clamp 17 is V-shaped. The movable clamp 17 and the top end of the clamp 3 cooperate to clamp and fix the wire. Specifically, the lifting eye bolt 18 is rotated by controlling the lifting eye portion. Since the lifting eye bolt 18 and the boss 301 are threadedly engaged, and the clamp 3 is hooked on the wire and is limited by the wire and will not rotate arbitrarily, the lifting eye bolt 18 moves up and down, which in turn drives the movable clamp 17 to move up and down.

[0041] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the installation mechanism includes a housing 4, on which a connecting plate 23 is fixedly installed. The connecting plate 23 is L-shaped, and the bottom end of the connecting plate 23 has a limiting part 2301 for supporting the bottom end of the surge arrester body 2. The limiting part 2301 is U-shaped and has a U-shaped groove for the fixing post 201 to pass through. A collar 5 is fixedly installed at the bottom of the limiting part 2301, and there is a gap between the top end of the collar 5 and the bottom end of the limiting part 2301 for the horizontal part of the claw 16 to be inserted. A sleeve 6 is detachably connected to the bottom of the collar 5 through a locking pin 25. An insulating rod 7 is inserted into the bottom end of the sleeve 6. The bottom end of the insulating rod 7 is fixed to the execution end of the working robot 38, and the working robot 38 controls the movement of the installation mechanism, etc.

[0042] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, a bracket 26 is rotatably mounted on the top of the collar 5, and a rotating rod 19 is mounted above the pawl 16 and fixed to the bracket 26. A secondary rack 1901 is fixedly connected to the end of the rotating rod 19 away from the bracket 26. A secondary gear 14 is axially fixedly sleeved on the rotating part 13 and meshes with the secondary rack 1901. A main rack 9 is fixedly connected to the end of the bracket 26 near the housing 4. A driving component is installed inside the housing 4. The driving component is a dual-output shaft servo motor 27. The dual-output shaft servo motor 27 is fixedly installed inside the housing 4. One output shaft of the dual-output shaft servo motor 27 extends from the bottom of the housing 4 and is fixedly mounted with a main gear 10. The main rack 9 meshes with the main gear 10. The other output shaft of the dual-output shaft servo motor 27 extends from the top of the housing 4 and is fixedly mounted with a rotating cylinder 8. The top of the rotating cylinder 8 is provided with a slot for the lifting eye portion of the lifting eye bolt 18 to be inserted.

[0043] When the dual-axis servo motor 27 is running, it drives the rotating drum 8 to rotate, which in turn drives the lifting eye bolt 18 to rotate, thereby adjusting the position of the moving clamp 17. At the same time, since the main rack 9 is meshed with the main gear 10, the main gear 10 drives the main rack 9 to rotate, and the rotating rod 19 and the auxiliary rack 1901 rotate synchronously, which causes the auxiliary gear 14 to drive the rotating part 13 to rotate, thereby adjusting the position of the pressure plate 15.

[0044] Reference Figure 3 , Figure 4 and Figure 6As shown, to improve the installation stability of the surge arrester body 2, a gripping assembly is provided on the housing 4. The gripping assembly includes two gripping arms 22, which are rotatably mounted on the housing 4 via pins 20. Both gripping arms 22 are fixedly provided with transmission teeth 2201, which mesh with each other. A drive motor 21 is fixedly installed on the side wall of the housing 4, and one of the pins 20 is fixedly connected to the drive shaft of the drive motor 21. The drive motor 21 drives the pin 20 and the corresponding gripping arm 22 to rotate. Under the action of the meshing transmission teeth 2201, the other gripping arm 22 rotates synchronously in the opposite direction, thereby realizing the clamping and releasing of the two gripping arms 22 on the outer side wall of the surge arrester body 2. During the lifting and installation process, the surge arrester body 2 is assisted in being fixed, preventing it from shaking or shifting, and further improving the installation stability and operational reliability.

[0045] Meanwhile, when the clamping assembly holds the surge arrester body 2 tightly, the fixing post 201 is inserted into the bottom groove of the surge arrester body 2, and the claw 16 and other structures also ensure the stability of the installation.

[0046] The actual working conditions are as follows: During the ground preparation phase, the horizontal part of the claw 16 is inserted into the gap between the collar 5 and the limiting part 2301. Then, the operator aligns the bottom groove of the surge arrester body 2 with the fixing post 201 and inserts it, so that the bottom end of the surge arrester body 2 is supported and positioned by the U-shaped limiting part 2301 of the connecting plate 23. At the same time, the lifting eye part of the lifting eye bolt 18 is inserted into the slot at the top of the rotating cylinder 8, and the gripping assembly holds the surge arrester body 2 tightly, completing the pre-installation check of the surge arrester body 2 and ensuring that all components are properly fitted and without loosening or displacement.

[0047] With the cooperation of the aerial work platform 39 and the work robot 38, the entire work tool and the lightning arrester body 2 are lifted to the installation position of the crossarm 1. First, the vertical part of the chuck 16 is initially engaged with the vertical section of the crossarm 1, and the gripper 3 is attached to the power line. Then, the dual-axis servo motor 27 is started. Through the transmission of the main gear 10, the main rack 9, the rotating rod 19, the auxiliary rack 1901 and the auxiliary gear 14, the rotating part 13 is driven to rotate in the forward direction. Under the coordinated guidance and limiting of the screw 12, the guide rod, the guide frame 11 and the protrusion 1501, the pressure plate 15 moves upward and presses against the inner corner of the crossarm 1, so as to realize the reliable locking of the fixing mechanism and the crossarm 1.

[0048] The dual-axis servo motor 27 synchronously drives the rotating drum 8 to rotate. The rotating drum 8 drives the lifting eye bolt 18 to rotate through the slot, causing the moving clamp 17 to move upward and cooperate with the gripper 3 to clamp the wire. Then, the installation mechanism is controlled to separate from the fixing mechanism and the wire clamp mechanism. Finally, the aerial lift vehicle 39 and the working robot 38 drive the installation mechanism to descend and reset, completing the entire uninterrupted power supply installation process.

[0049] Reference Figure 10As shown, when the insulating rod 7 is set long enough, it can also be held by the operator for lifting and installation operations.

[0050] Example 2, the present invention provides as follows Figures 12-17 The power distribution network uninterrupted installation tool for surge arresters shown has a synchronization component on the top of the housing 4 to facilitate the disassembly of the surge arrester body 2. The synchronization component includes a threaded post 28, which is slidably mounted on the output shaft of the dual-output shaft servo motor 27 extending from the top of the housing 4. The output shaft and the threaded post 28 are fitted with a rectangular slot and a rectangular block, meaning that the threaded post 28 can rotate synchronously with the output shaft or slide on the output shaft. Both sides of the top of the threaded post 28 are hinged to limit seats 30 via hinge shafts. A channel 31 is formed between the two limit seats 30 for the lifting eye bolt 18 to extend into. A torsion spring 29 is mounted on the hinge shaft. One end of the torsion spring 29 is fixedly connected to the limit seat 30, and the other end of the torsion spring 29 is fixedly connected to the threaded post 28. When not affected by other external forces, under the elastic support force of the torsion spring 29, the top of the limit seat 30 swings away from the axis of the threaded post 28.

[0051] The limiting seat 30, facing away from the axis of the threaded column 28, is configured from bottom to top as an inclined section 3001, a vertical section 3002, and a flange section 3003. The bottom end of the inclined section 3001 is inclined towards the axis of the threaded column 28, and the height of the vertical section 3002 is appropriate. The threaded column 28 is externally threaded with a threaded sleeve 33, and a support rod 32 is fixedly installed on the threaded sleeve 33. The bottom end of the support rod 32 is fixed to the top of the housing 4, so that the position of the threaded sleeve 33 is fixed. At the same time, a fixing rod 35 is fixedly connected to the top of the threaded sleeve 33, and a ring 34 is fixedly connected to the top of the fixing rod 35. The ring 34 surrounds the outside of the two limiting seats 30. When the flange section 3003 abuts against the top of the ring 34, the limiting effect is achieved.

[0052] Specifically, when the inclined section 3001 corresponds to the ring 34, under the restoring force of the torsion spring 29, the top of the limiting seat 30 swings away from the axis of the threaded column 28, and the two limiting seats 30 open in a V shape; when the vertical section 3002 corresponds to the ring 34, the insertion channel 31 is rectangular, and its width is adapted to the width of the lifting ring. After the lifting ring is inserted into the insertion channel 31, the lifting ring bolt 18 can be driven to rotate when the two limiting seats 30 rotate with the threaded column 28; and the limiting seat 30 rotates inside the ring 34, and the inner ring of the ring 34 is movably inlaid with balls (not shown in the figure), which reduces the wear between the limiting seat 30 and the ring 34 during the rotation.

[0053] During installation: the vertical section 3002 corresponds to the circular ring 34, and the width of the insertion channel 31 is adapted to the width of the lifting ring part; during the ground preparation stage, the lifting ring part of the lifting ring bolt 18 is inserted into the insertion channel 31 to ensure that the wire clamp mechanism is stably supported.

[0054] When connecting to the wire, the dual-axis servo motor 27 drives the threaded column 28 to rotate, and the two limit seats 30 rotate synchronously with the threaded column 28 and drive the eye bolt 18 to rotate, thereby causing the moving clamp 17 to move upward and clamp and fix the wire; and because the height of the vertical section 3002 is set appropriately, the insertion channel 31 is kept in a suitable position to match the width of the eye part for an appropriate period of time, and the eye bolt 18 rotates stably.

[0055] When the inclined section 3001 aligns with the ring 34, under the restoring force of the torsion spring 29, the top of the limiting seat 30 swings away from the axis of the threaded column 28, and the two limiting seats 30 open in a V shape, realizing the rapid separation of the limiting seat 30 and other structures from the eye bolt 18.

[0056] During disassembly: the inclined section 3001 corresponds to the ring 34. Under the action of the return spring force of the torsion spring 29, the top of the limit seat 30 swings away from the axis of the threaded column 28. The two limit seats 30 open in a V shape, lifting the entire working tool to the installation position of the crossbeam 1. The lifting eye part of the lifting eye bolt 18 can quickly extend into the V-shaped insertion channel 31, shortening the docking time and reducing the complexity of operation.

[0057] The dual-axis servo motor 27 drives the threaded column 28 to rotate, and the two limit seats 30 rotate synchronously with the threaded column 28 inside the ring 34. At the same time, since the threaded column 28 and the threaded sleeve 33 are threadedly engaged, the threaded column 28 will also move downward. The two limit seats 30 are gradually squeezed and guided by the ring 34 until the vertical section 3002 corresponds to the ring 34. At this time, the width of the insertion channel 31 is matched with the width of the lifting ring. The two limit seats 30 drive the lifting ring bolt 18 to rotate, thereby causing the moving clamp 17 to move downward and release the clamping and fixing of the wire. The lifting ring bolt 18 is stably inserted into the insertion channel 31 to ensure the lifting and fixing of the wire clamp mechanism.

[0058] Reference Figure 16 As shown, considering that the clamp 3 is prone to shaking due to the swaying and pulling of the wire during actual use, which may cause the eye bolt 18 to loosen, in order to improve the stability of the eye bolt 18, a vertical plate 36 is hinged to the bottom of the boss 301. The bottom end of the vertical plate 36 is provided with a bend 3601, and the bottom end of the bend 3601 is inclined away from the eye bolt 18. The top end of the bend 3601 corresponds to the middle section of the eye bolt 18. The bend 3601 abuts against the ring 34. A spring 37 is fixedly connected to the top end of the vertical plate 36 on the side away from the eye bolt 18. The end of the spring 37 away from the vertical plate 36 is fixedly connected to the bottom of the boss 301, and the elastic support force of the spring 37 is large.

[0059] Reference Figure 16As shown, after the movable clamp 17 and the clamping claw 3 clamp and fix the wire, the vertical plate 36 is pressed against the eye bolt 18 by the elastic support force of the spring 37, so that the eye bolt 18 will not rotate at will; when installing or disassembling, the ring 34 abuts against the bend 3601, so that the bottom end of the vertical plate 36 swings away from the eye bolt 18, and the vertical plate 36 separates from the eye bolt 18 without affecting the rotation of the eye bolt 18.

[0060] Reference Figure 17 As shown, to reduce the pressure on the wires, before installation, side rods 40 are movably inserted into the outer ring of the ring 34. Multiple side rods 40 are provided, and the multiple side rods 40 are evenly distributed around the axis of the ring 34. The side rods 40 are of appropriate length to ensure stable contact with the vertical plate 36. Specifically, during installation or disassembly, the ring 34 abuts against the bend 3601, causing the bottom end of the vertical plate 36 to swing away from the lifting eye bolt 18, separating the vertical plate 36 from the lifting eye bolt 18. At the same time, the vertical plate 36 is limited between the corresponding two side rods 40, so that the clamping claws 3 and other structures will not rotate arbitrarily, thereby ensuring that the lifting eye bolt 18 rotates stably on the boss 301 and reducing the squeezing and pulling of the wires by the clamping claws 3 during rotation.
