Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a UAV-based spacer bar electrified mounting device. Background Technology

[0002] With the continuous expansion of my country's overhead power distribution lines and technological upgrades, the mass per unit length of conductors, the mass of fittings, and the diameter of conductors have increased significantly, leading to a substantial increase in the risk of line galloping. Conductor galloping easily causes phase-to-phase cross contact, resulting in serious accidents such as conductor wear, fitting damage, and even line breakage, severely threatening the safe and stable operation of the power grid. To effectively prevent conductor cross contact, spacers are typically used to fix the distance between conductors. Due to their excellent insulation performance and mechanical strength, spacers can effectively support and constrain different phase conductors, demonstrating significant effectiveness in suppressing conductor galloping and becoming a standard anti-galloping measure for power companies.

[0003] In the installation of anti-galling devices for overhead power distribution lines, the installation of spacers has long relied on manual labor at height. However, manual installation suffers from significant problems such as low efficiency and high safety risks. In recent years, with the rapid development of drone technology, using drones to hoist spacers between two conductors for installation has become a promising alternative. Drone operations can effectively avoid personnel working at height with live conductors, improving construction safety.

[0004] However, in actual operating environments, due to factors such as high-altitude wind disturbances and changes in conductor direction and sag, it is difficult for drones to achieve precise positioning between the two conductors during flight, making it difficult to align and install spacers between the two conductors, and the installation accuracy and success rate cannot meet the requirements of engineering applications.

[0005] Therefore, this application proposes a live mounting device for spacers based on unmanned aerial vehicles (UAVs) that facilitates precise positioning of spacers and cable conductors. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a spacer bar electrified mounting device based on a drone.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A drone-based spacer bar electrified mounting device, comprising a drone; The drone is equipped with a mounting assembly for deploying spacer bars. The mounting assembly includes a positioning component for determining the cable position and a mounting frame for placing the spacer bars. The mounting frame is used to accurately place the spacer bar onto the cable surface. The mounting frame includes a vertically arranged guide rail and two limiting rods for limiting the height of the spacer bar. A groove for installing the spacer bar is provided on one side of the guide rail.

[0008] In some embodiments, the positioning assembly includes two clamping rods hinged to the bottom of a first housing and a push plate for actuating the two clamping rods to perform a clamping action, the two clamping rods being scissor-hinged.

[0009] In some embodiments, the two positioning components are respectively positioned below the drone via two first traction ropes, and the two first traction ropes are respectively wound and unwound via a winding component.

[0010] In some embodiments, the spacer is installed inside the groove of the guide rail by a traction frame. The traction frame includes a retaining ring sleeved on the end of the spacer and a limiting ball rod that slides vertically inside the groove of the guide rail. The limiting ball rod is fixed to the surface of the retaining ring by a connecting rod, which is obliquely arranged.

[0011] In some embodiments, the limiting ball rod is spherical at one end of the groove, and the groove cross-section of the guide rail is an arc shape that matches the limiting ball rod.

[0012] In some embodiments, multiple speed reduction plates are fixed on both sides of the inner wall of the guide rail groove, and the multiple speed reduction plates are all located at the opening of the groove.

[0013] In some embodiments, the guide rail is height-adjusted by a lifting assembly. There are multiple lifting assemblies, which are located on both sides of the two first housings. Each lifting assembly includes a fixed plate and a guide rope fixed to the surface of the first traction rope. The fixed plate slides vertically on the surface of the guide rope through multiple guide slip rings. A mounting frame is provided on the side of each of the multiple fixed plates that is far apart from each other.

[0014] In some embodiments, the two first traction ropes are width-adjustable via a support assembly to accommodate spacers of different lengths. The support assembly includes a sleeve and a threaded rod inserted inside the sleeve. The sleeve has a nut rotatably connected to one end of the threaded rod, and the nut is threaded onto the surface of the threaded rod.

[0015] In some embodiments, clamping assemblies are provided at both ends of the spacer bar. Each clamping assembly includes a hook fixed to the end of the spacer bar and a top ring that slides horizontally inside the hook. The top ring is driven to slide horizontally by a ball screw, and a tension spring is sleeved on the surface of the ball screw to drive the top ring to perform a clamping action with the hook.

[0016] In some embodiments, the top ring is kept separated from the bent end of the hook by a first limiting component. The first limiting component includes a top rod for abutting the top ring and a top plate for abutting the side of the guide rail facing the spacer bar. The top rod is located between the top ring and the bent end of the hook, and the top plate slides elastically on the side of the hook facing the guide rail. The other end of the top plate corresponds to the guide rail.

[0017] Compared with the prior art, the present invention provides a spacer bar electrified mounting device based on a drone, which has the following beneficial effects.

[0018] 1. This invention uses two sets of positioning components. In the normal state, the bottom of the two clamping rods are open and set in an inverted V shape, which makes it easy to move the two clamping rods from above the cable and fit them onto the cable surface. By clamping the cable with the two clamping rods, the positioning components and the mounting frame are bound to the cable. This can reduce cable galloping and prevent the mounting components from shaking, which would affect the relative positioning of the spacer and the cable. This allows the two ends of the spacer to be quickly positioned above the cable.

[0019] 2. This invention, by setting up multiple mounting frames, can simultaneously mount multiple spacer bars under the drone, reducing the number of times the drone needs to be transported back and forth, shortening the overall mounting operation time, and effectively improving the efficiency of replacing spacer bars while the power is on.

[0020] 3. In this invention, by fitting the limiting ball rod in a spherical shape with the guide rail groove, the limiting ball rod can roll within the guide rail groove, thereby allowing the spacer bar to be installed obliquely inside the guide rail, adapting to cables of different horizontal heights.

[0021] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Reference Figure 1-16 A spacer bar electrified mounting device based on a drone includes a drone 1 and a mounting component 2 for deploying spacer bars 6, the mounting component 2 being located below the drone 1. The mounting assembly 2 includes a positioning assembly 201 for determining the position of the cable and a mounting frame 202 for placing the spacer bar 6. There are two sets of positioning assemblies 201, which are used to simultaneously position the two cables. The positioning assembly 201 includes two clamping rods 2011 hinged to the bottom of the first housing 2012 and a push plate 2013 for driving the two clamping rods 2011 to perform clamping actions. The two clamping rods 2011 are scissor-hinged. The two push plates 2013 are threaded to the surface of the positive and negative threaded columns 2014 respectively. The upper end of the push plate 2013 abuts against the top of the first housing 2012. The positive and negative threaded columns 2014 rotate laterally inside the first housing 2012. The upper ends of the two clamping rods 2011 are located between the two push plates 2013. The upper ends of the two clamping rods 2011 are separated from each other by springs. The positive and negative threaded columns 2014 are driven to rotate by a drive motor. Both clamps 2011 are curved.

[0041] Understandably, due to the wind's influence at high altitudes, the cable vibrates, and the mounting component 2 also sways during the flight of the UAV 1. This makes it difficult for the UAV 1, carrying the spacer 6, to align the two ends of the spacer 6 with the cable, typically requiring a significant amount of time to deploy the spacer 6 onto the cable. Therefore, to quickly align the two ends of the spacer 6 with the cable, two sets of positioning components 201 are installed. In the normal state, the bottoms of the two clamping rods 2011 are open, forming an inverted V shape, facilitating the placement of the two clamping rods 2011 from... The upper part of the cable moves and fits onto the cable surface. Then, the drive motor drives the positive and negative threaded column 2014 to rotate, causing the two push plates 2013 to move closer to each other. The two push plates 2013 press the upper ends of the two clamping rods 2011 closer to each other, and the lower ends of the two clamping rods 2011 retract synchronously to clamp the cable. This binds the positioning component 201 and the hanger 202 to the cable, which can reduce cable running and prevent the hanger component 2 from shaking, affecting the relative positioning of the spacer 6 and the cable. This allows the two ends of the spacer 6 to be quickly positioned above the cable. Meanwhile, the clamping rod 2011 is set to an arc shape. After the clamping rod 2011 clamps the cable, it can form a hoop shape to prevent the cable from sliding laterally between the two clamping rods 2011 when it shakes, thus preventing it from being unable to achieve stable clamping and detaching from the clamping rods 2011.

[0042] Specifically, the two positioning components 201 are respectively set below the drone 1 by two first traction ropes 3. The two first traction ropes 3 are respectively wound and unwound by a winding component 4. The winding component 4 includes a winding wheel 401 that rotates inside the second housing 402. The second housing 402 is fixed to the bottom of the drone 1. The winding wheel 401 is driven to rotate by a drive motor. The lower end of the first traction rope 3 is fixed to the top of the first housing 2012, and the upper end of the first traction rope 3 is wrapped around the surface of the winding wheel 401.

[0043] Understandably, by driving the winding wheel 401 to rotate via the drive motor, the extension length of the first traction rope 3 can be adjusted accordingly. This allows for adjustment of the lowering height of the mounting component 2 based on on-site operational requirements, adapting to cable operation scenarios at different heights. By winding the two traction ropes with two sets of winding components 4 respectively, the height of both ends of the spacer 6 can be adjusted. This allows for the adaptation to cables of the same height as well as cables with height differences, enabling the spacer 6 to be installed at an angle. This ensures that the mounting operation can match different line conditions and expands the applicability of the device.

[0044] Specifically, the mounting bracket 202 is used to accurately place the spacer 6 onto the cable surface. The two mounting brackets 202 are respectively installed on the surfaces of the two first traction ropes 3 through two lifting components 203, and the two mounting brackets 202 are arranged opposite to each other. The mounting bracket 202 includes a vertically arranged guide rail 2021 and a limiting rod 2022 for limiting the height of the spacer 6. A groove for installing the spacer 6 is provided on one side of the guide rail 2021. The limiting rod 2022 slides laterally inside the guide rail 2021. The limiting rod 2022 is driven to slide by a linear motor, which is fixed to the side of the guide rail 2021. There are two limit rods 2022, and the two limit rods 2022 are set at different heights of the guide rail 2021, so as to simultaneously install the two spacer bars 6 inside the guide rail 2021; The spacer 6 is installed inside the groove of the guide rail 2021 via the traction frame 204. The traction frame 204 includes a retaining ring 2041 sleeved on the end of the spacer 6 and a limiting ball rod 2043 that slides vertically inside the groove of the guide rail 2021. The retaining ring 2041 is C-shaped and is fixed to the end of the spacer 6 by locking bolts. The limiting ball rod 2043 is fixed to the surface of the retaining ring 2041 via a connecting rod 2042. The connecting rod 2042 is obliquely arranged, and a balance rod 2044 is fixed to the surface of the connecting rod 2042. The balance rod 2044 abuts against the surface of the guide rail 2021, and the balance rod 2044 and the limiting ball rod 2043 are at the same horizontal height.

[0045] Understandably, when installing the spacer 6, the traction frame 204 is first fixed to the end of the spacer 6. The retaining ring 2041 is then fitted onto the end of the spacer 6 and secured to the surface of the spacer 6 with locking bolts. The limiting ball rod 2043 is inserted into the groove of the guide rail 2021. Simultaneously, the balance rod 2044 abuts against the surface of the guide rail 2021. The limiting rod 2022 limits the height of the spacer 6, preventing it from falling. This allows the spacer to be positioned within the spacer. The spacer 6 is stably placed on the surfaces of the two mounting brackets 202. After the positioning component 201 clamps the cable, the two ends of the spacer 6 correspond to the two cables respectively. At this time, the linear motor drives the limiting rod 2022 to slide out of the groove of the guide rail 2021, losing the support of the limiting ball rod 2043. Under the action of gravity, the spacer 6 slides down into the groove of the guide rail 2021 to the cable surface through the limiting ball rod 2043, thereby accurately and quickly placing the spacer 6 onto the cable surface.

[0046] Specifically, the limiting ball rod 2043 is spherical at one end of the groove, and the groove cross section of the guide rail 2021 is an arc shape that matches the limiting ball rod 2043.

[0047] It is understandable that by mates the limiting ball 2043 with the groove of the guide rail 2021 in a spherical shape, the limiting ball 2043 can roll within the groove of the guide rail 2021, thereby allowing the spacer 6 to be installed obliquely inside the guide rail 2021 to accommodate cables at different horizontal heights.

[0048] Specifically, multiple speed reduction plates 2023 are fixed on both sides of the inner wall of the groove of the guide rail 2021. All speed reduction plates 2023 are located at the opening of the groove. The speed reduction plates 2023 are elastic plates set at an angle downward. The distance between speed reduction plates 2023 at the same height is less than the diameter of the limiting ball rod 2043.

[0049] Understandably, the upper spacer 6 is far from the cable. When the upper spacer 6 falls downwards, to avoid excessive descent speed and collision with the cable causing damage, an elastic deceleration plate 2023 is installed. When the spacer 6 slides downwards through the limiting ball rod 2043, the limiting ball rod 2043 compresses the elastic deceleration plate 2023. The deceleration plate 2023 deforms into a vertical position after being compressed, reducing the falling speed of the limiting ball rod 2043. As the spacer 6 gradually falls, the deceleration plate 2023 decelerates the limiting ball rod 2043 one by one, finally allowing the spacer 6 to land smoothly on the cable surface. This ensures the accuracy of the landing and avoids excessive impact force that could damage the cable and the spacer 6.

[0050] Specifically, the guide rail 2021 has its height adjusted by lifting components 203. Multiple lifting components 203 are located on either side of the two first housings 2012. Each lifting component 203 includes a fixing plate 2031 and a guide rope 2032 fixed to the surface of the first traction rope 3. Multiple guide rings 2034 are fixed to the side of the fixing plate 2031 away from the guide rail 2021. The fixing plate 2031 slides vertically on the surface of the guide rope 2032 via the guide rings 2034. Both ends of the guide rope 2032 are fixed to the first traction rope 3. On the surface, two support rods 2033 are fixed between the guide rope 2032 and the first traction rope 3. The two support rods 2033 are located at the top and bottom of the guide rope 2032, respectively. Multiple guide slip rings 2034 are located between the two support rods 2033. The guide rail 2021 is fixed on the surface of the fixing plate 2031. The bottom of the fixing plate 2031 is in contact with the side of the first housing 2012 to prevent the fixing plate 2031 from rotating on the surface of the guide rope 2032. Hanging frames 202 are respectively provided on the side of the multiple fixing plates 2031 that are far apart from each other.

[0051] Understandably, since the spacer 6 slides down along the guide rail 2021 to the cable surface, the limiting ball rod 2043 is still in the groove of the guide rail 2021. Therefore, by sliding the fixing plate 2031 upward on the surface of the guide rope 2032, the guide rail 2021 actively disengages from the limiting ball rod 2043, allowing the UAV 1 to carry the mounting component 2 smoothly to the next position. At the same time, the fixing plate 2031 can drive the spacer 6 to adjust its initial height, which can adapt to the mounting requirements of different cables and improve the adaptability of the device. By setting up multiple mounting brackets 202, multiple spacer bars 6 can be mounted under the UAV 1 at the same time, reducing the number of times the UAV 1 needs to be transported back and forth, shortening the overall mounting operation time, and effectively improving the efficiency of replacing spacer bars 6 while the power is on.

[0052] Specifically, a telescopic rod 205 is provided between two fixed plates 2031 on the same side of the first housing 2012. The two ends of the telescopic rod 205 are respectively hinged to the surfaces of the two fixed plates 2031. A second traction rope 206 is fixed to the surfaces of the two telescopic rods 205. The second traction rope 206 is wound and released by another set of winding components 4. The other set of winding components 4 is set at the bottom of the UAV 1.

[0053] It is understandable that the second traction rope 206 is wound and unwound by another set of winding components 4, thereby driving multiple spacer bars 6 to adjust their height through the fixed plate 2031, adjusting the height difference between the spacer bars 6 and the positioning component 201, and improving the flexibility of adjustment; the telescopic rod 205 can be freely adjusted in length to accommodate spacer bars 6 of different lengths. The telescopic rod 205 is hinged to the surface of the fixed plate 2031 at both ends, so that when the spacer bars 6 need to be tilted, the fixed plate 2031 at both ends can be raised and lowered at different heights.

[0054] Specifically, the width of the two first traction ropes 3 is adjusted by the support assembly 5 to accommodate spacer bars 6 of different lengths. The support assembly 5 includes a sleeve 501 and a threaded rod 502 inserted inside the sleeve 501. A nut 503 is rotatably attached to one end of the sleeve 501 facing the threaded rod 502. The nut 503 is threaded onto the surface of the threaded rod 502. The ends of the sleeve 501 and the threaded rod 502 that are far apart from each other are respectively fixed to the surfaces of the two first traction ropes 3 by a fixing ring 504. A locking bolt is provided on the surface of the fixing ring 504, and the fixing ring 504 is fixed to the surface of the first traction rope 3 by the locking bolt.

[0055] It is understandable that by setting up the support component 5, after fixing the support component 5 to the middle of the first traction rope 3 with the locking bolt, rotating the nut 503 causes the threaded rod 502 to extend or retract from the sleeve 501, changing the overall length of the support component 5, thereby adjusting the distance between the two first traction ropes 3, adapting to spacer bars 6 of different lengths, so that the first traction ropes 3 located below the support component 5 are parallel, making it easier for the fixing plate 2031 to slide up and down on the surface of the guide rope 2032, and avoiding the sliding jamming of the fixing plate 2031 caused by the non-parallel first traction ropes 3.

[0056] Specifically, clamping components 7 are provided at both ends of the spacer 6. The spacer 6 is automatically fixed to the cable surface by the clamping components 7. The clamping components 7 include a hook 701 fixed to the end of the spacer 6 and a top ring 702 that slides horizontally inside the hook 701. The opening of the hook 701 faces downward. The top ring 702 is driven to slide horizontally by a ball screw 703. The ball screw 703 is threadedly connected to a ball nut. The ball nut is rotatably connected inside the hook 701. The upper surface of the top ring 702 abuts against the inner top wall of the hook 701. A tension spring is sleeved on the surface of the ball screw 703 to drive the top ring 702 and the hook 701 to perform clamping action. Insulating pads are provided on opposite sides of the hook 701 and the top ring 702.

[0057] Understandably, since this device can carry multiple spacer bars 6 simultaneously, and all spacer bars 6 move within the guide rail 2021, it is difficult to provide power to the spacer bars 6, making it unsuitable for existing electrically driven spacer bars 6 that can be automatically fixed to the cable surface. Therefore, by setting up a clamping assembly 7, when the spacer bar 6 slides down to the cable surface, the tension spring stores the force, driving the ball screw 703 and the top ring 702 to generate a thrust towards the bent end of the hook 701. Since the friction between the ball screw 703 and the ball nut is small, the ball screw 703 can drive the ball nut to rotate, thereby allowing the ball screw 703 to drive the top ring 702 to move. With the cooperation of the top ring 702 and the end of the hook 701, the cable is clamped, thus automatically fixing the spacer bar 6 to the cable surface without relying on external power.

[0058] Specifically, the top ring 702 is kept separated from the bent end of the hook 701 by the first limiting component 704; refer to Figure 10 or Figure 15 The first limiting component 704 includes a push rod 7041 for abutting against the top ring 702 and a top plate 7042 for abutting against the side of the guide rail 2021 facing the spacer bar 6. The push rod 7041 is located between the top ring 702 and the bent end of the hook 701. The push rod 7041 is fixed to the end of the top plate 7042. The top plate 7042 slides elastically on the side of the hook 701 facing the guide rail 2021. The other end of the top plate 7042 corresponds to the guide rail 2021.

[0059] It is understandable that by setting the first limiting component 704, the top ring 702 is kept separated from the end of the hook 701. After the spacer 6 is placed inside the guide rail 2021 by the limiting ball 2043, the hook 701 drives the top plate 7042 to abut against the surface of the guide rail 2021, thereby pushing the top plate 7042 and causing the top rod 7041 to move between the top ring 702 and the bent end of the hook 701, keeping the top ring 702 separated from the end of the hook 701. When the hook 701 is attached to the surface of the cable, the limiting ball 2043 is at the bottom of the guide rail 2021, and the top plate 7042 is separated from the guide rail 2021. This causes the spring inside the hook 701 to push the top plate 7042 away from the hook 701. At the same time, the top rod 7041 disengages from the top ring 702, allowing the top ring 702 to approach the end of the hook 701 for clamping. Since the hook 701 has not yet been attached to the cable surface when the top plate 7042 just leaves the guide rail 2021, if the top ring 702 is driven to approach the end of the hook 701 by using a tension spring and sliding rod, the sliding speed of the top ring 702 will be too fast, which may cause the top ring 702 to complete the clamping prematurely before the hook 701 is aligned with the cable position, resulting in clamping failure. Therefore, by setting a ball screw 703 and a ball nut, the ball screw 703 increases the travel of the top ring 702 and controls the movement speed of the top ring 702, allowing sufficient time for the hook 701 to slide down to the cable surface, avoiding premature clamping and misalignment, and ensuring that the device can accurately hang the spacer 6 on the cable surface.

[0060] Specifically, the top ring 702 is prevented from separating from the cable by the second limiting component 705. The second limiting component 705 includes a rod 7051 that slides elastically inside the hook 701 and a plurality of slots 7052 formed on the surface of the ball nut. The plurality of slots 7052 are arranged in a ring on the surface of the ball nut. The rod 7051 corresponds to the slot 7052. The tail of the ball screw 703 is provided with a protrusion for abutting the rod 7051. The tail end of the rod 7051 is L-shaped and extends to the outside of the hook 701.

[0061] Under normal conditions, the insert rod 7051 is separated from the slot 7052. When the ball screw 703 slides inward to its position, the protrusion at the tail of the ball screw 703 pushes the insert rod 7051 into one of the slots 7052, limiting the rotation of the ball nut. At this time, the ball nut and the ball screw 703 are relatively fixed, thereby limiting the displacement of the ball screw 703 and the top ring 702 and preventing the top ring 702 from loosening. When it is necessary to remove the spacer bar 6, the insert rod 7051 is moved to separate it from the slot 7052, thereby releasing the limitation on the ball nut.

[0062] In this invention, before installing the spacer 6, the distance between the two first traction ropes 3 is first adjusted. If cables of different heights are being installed, the release length of the two first traction ropes 3 also needs to be adjusted so that the mounting components 2 on both sides are at different heights. The distance between the first traction ropes 3 is adjusted according to the vertical distance between the two cables using the support component 5. When installing the spacer 6, the traction frame 204 is first fixed to the end of the spacer 6. The retaining ring 2041 is sleeved on the end of the spacer 6 and fixed to the surface of the spacer 6 using locking bolts. The limiting ball rod 2043 is then inserted into the guide rail 2021. Within the groove, the balance bar 2044 abuts against the guide bar surface, and the height of the spacer bar 6 is limited by the limiting rod 2022 to prevent the spacer bar 6 from falling. After multiple spacer bars 6 are installed, the drone 1 takes off and moves above the cable. The cable is positioned by the positioning component 201, and the two open clamping rods 2011 are fitted onto the cable surface. The push plate 2013 is driven by the positive and negative threaded column 2014 to clamp the upper end of the clamping rods 2011, so that the lower ends of the two clamping rods 2011 are simultaneously closed to clamp the cable. The positioning component 201 and the mounting frame 202 are bound to the cable, which can reduce cable swaying and prevent the mounting component 2 from shaking. The movement proceeds, and then the spacer 6 at the bottom of one side becomes the first object to be installed. A linear motor drives the limit rod 2022 to slide out of the groove of the guide rail 2021, losing support from the limit ball rod 2043. Under gravity, the spacer 6 slides downwards through the limit ball rod 2043 into the groove of the guide rail 2021 to the cable surface. At this point, the limit ball rod 2043 is at the bottom of the guide rail 2021, while the top plate 7042 is separated from the guide rail 2021. This causes the spring inside the hook 701 to push the top plate 7042 away from the hook 701. Simultaneously, the top rod 7041 disengages from the top ring 702, and the tension spring and ball screw 7... Under the action of 03, the top ring 702 can approach the end of the hook 701 to perform a clamping action. When the ball screw 703 slides inward into place, the protrusion at the tail of the ball screw 703 pushes the insertion rod 7051 to insert into one of the slots 7052, limiting the rotation of the ball nut and completing the fixed installation of the spacer 6. Through another set of winding components 4, the telescopic rod 205 and the fixing plate 2031 slide upward on the surface of the guide rope 2032, so that the guide rail 2021 actively disengages from the limiting ball rod 2043, allowing the UAV 1 to carry the mounting component 2 smoothly to the next position for continuous installation of the spacer 6.
