Description

Technical Field

[0001] This utility model relates to the technical field of tower climbing auxiliary equipment, specifically to an anti-backward mounting device. Background Technology

[0002] Currently, power grid workers frequently need to climb power transmission towers during routine maintenance. Initially, this requires manual pre-climbing, but the first worker ascends without a safety rope. Due to factors such as the climbing environment and the worker's psychological state, both the worker and their tools are at risk of falling, making the climb extremely dangerous. Furthermore, traditional methods rely on rope loops and hooks with foot spikes as anchor points. However, the open design of these foot spikes can cause the rope loops to slip out, and the bolts may deform or break due to impact, compromising reliability. Additionally, the traditional method requires manual alternation of safety hooks, which is physically demanding and increases the risk of falls.

[0003] To address the aforementioned issues, existing technologies typically employ drones to connect to docking devices. These devices are then docked and locked to the mounting device, with the fall arrestor rope pre-fixed to the mounting device. The drone then transports the mounting device and fall arrestor rope to the angle steel at the top of the tower. This eliminates the need for manual pre-climbing, reducing initial operational risks. Furthermore, the fall arrestor rope acts as a flexible guide rail, allowing workers to climb the tower simply by wearing safety harnesses and attaching fall arrestors to the rope. This method also significantly improves climbing efficiency.

[0004] The existing mounting devices have poor fall protection performance. After being mounted on the angle steel at the top of the tower, the existing mounting devices are prone to swaying, tilting, and backing. When a person accidentally falls and causes a momentary and continuous impact on the mounting device, it is easy for the mounting device to tilt or even fall, thus causing the risk of people falling. Utility Model Content

[0005] This utility model provides an anti-reverse mounting device, which aims to prevent the mounting device from accidentally falling off the angle steel of the tower and ensure the safety of personnel during operation.

[0006] This utility model is achieved through the following technical solution: an anti-reverse mounting device, comprising a mounting bracket docking unit and a mounting bracket, wherein the mounting bracket docking unit is vertically slidingly engaged with the mounting bracket;

[0007] The two ends of the bracket are the end point for clamping the tower and the starting point away from the tower, respectively. A retractable slider is horizontally slidable on the bracket. When the retractable slider slides to the end point, it can engage with one side of the bracket to lock the tower. The bracket is provided with a drive component for driving the retractable slider to slide.

[0008] The hanger is equipped with a locking and retraction unit for restricting the retraction of the retractable slider; the locking and retraction unit includes a locking device and a locking bar, the locking device is fixed on the retractable slider, and the locking bar is fixed on the hanger, the locking device and the locking bar can lock together; a connector is connected to the hanger docking unit, and the end of the connector away from the hanger docking unit is connected to the locking device; the movement of the connector can cause the locking device and the locking bar to unlock or lock each other.

[0009] One type of anti-reverse mounting device in this solution includes a mounting docking unit and a mounting bracket. The mounting docking unit can connect to the docking device on the UAV, while the mounting bracket is used to hang on the tower and fix it to the tower. By connecting the fall arrestor rope to the mounting bracket, the fall arrestor rope can be installed on the tower after the mounting bracket is fixed to the tower. This makes it convenient for workers to connect the fall arrestor on their safety belt to the fall arrestor rope for tower climbing operations.

[0010] In this application, a retractable slider slides horizontally on the bracket, and a drive component drives the retractable slider to move. After the bracket is hung on the tower, the retractable slider is driven to move to the end position of the bracket, so that the retractable slider and one side of the bracket are engaged and locked onto the tower, ensuring the stability of the anti-backward mounting device of this application after installation.

[0011] This application also includes a locking and retraction unit on the hanger. The locking and retraction unit includes a locking device and a locking bar that lock together. Since the hanger docking unit slides vertically with the hanger, and a connector is connected to the hanger docking unit, the connector will be tightened or loosened as the hanger docking unit slides vertically back and forth. Therefore, the connector will cause the locking device and the locking bar connected to it to be unlocked or locked. The locking device is fixed on the retraction slider. Therefore, after the connector drives the locking device and the locking bar to unlock, it can drive the retraction slider to move together. Specifically: when the hanger docking unit slides upward, the connector drives the locking device and the locking bar to unlock, and at this time the connector can drive the retraction slider to move to the starting position; when the hanger docking unit slides downward to reset, the connector drives the locking device and the locking bar to lock. Under the action of the driving component, the driving component can drive the retraction slider to move to the end position, thereby realizing that the retraction slider is away from or close to the end position, which is convenient for cooperating with one side of the hanger to clamp the tower angle steel or move away from the tower angle steel.

[0012] This solution incorporates a locking and retraction unit. By locking the device and locking bar, the stability of the connection between the retractable slider and the tower is enhanced, preventing the mounting device from accidentally falling off the tower angle steel and ensuring the safety of personnel during operation.

[0013] Furthermore, the driving component includes a coil spring and a coil spring shaft. The two ends of the coil spring shaft are rotatably connected to the two sides of the hanging bracket, respectively. The coil spring is wound around the coil spring shaft, one end of the coil spring is fixed to the coil spring shaft, and the other end of the coil spring is fixedly connected to the retractable slider.

[0014] In this design, the driving component uses a coil spring to pull the retractable slider towards the clamping angle steel, thereby engaging with one side of the bracket to secure the angle steel. The driving component has a simple structure, with the coil spring, connecting component, and bracket docking unit working in tandem. When the bracket docking unit slides upward, causing the connecting component to tighten and pull the retractable slider towards the starting position, the coil spring is stretched. Conversely, when the bracket docking unit slides downward, causing the connecting component to loosen and unfold, the coil spring pulls the retractable slider towards the end position, clamping and fixing it onto the tower angle steel.

[0015] Furthermore, the locking device includes a mounting component and a pawl. The mounting component is fixedly connected to the retractable slider. Rotating plates are fixedly connected to both sides of the pawl, and the two rotating plates are rotatably connected to both sides of the mounting component. An elastic element is provided between the pawl and the mounting component. One end of the connecting component is fixedly connected to the pawl, and the pawl and the locking bar can engage or disengage with each other.

[0016] The locking device in this design includes a mounting component and a pawl. The mounting component facilitates connection with the retractable slider, while the pawl is rotatably connected to the mounting component via a rotating plate. An elastic element is provided between the pawl and the mounting component. When the connecting component connected to the pawl is tightened or loosened during the vertical movement of the hanger docking unit, it will pull the pawl away from the locking bar to achieve the unlocked state. Alternatively, during the loosening and resetting of the connecting component, the pawl will reset under the action of the elastic element and re-engage with the locking bar to lock. In this design, the pawl and the locking bar are engaged by teeth, resulting in a good locking effect.

[0017] Furthermore, the elastic element is a torsion spring, and a connecting shaft is provided between the rotating plate and the mounting component. The rotating plate and the mounting component are rotatably connected through the connecting shaft. The torsion spring is sleeved on the connecting shaft, and both ends of the torsion spring are fixed to the mounting component and the pawl, respectively.

[0018] The elastic element in this solution is a torsion spring. Under the pulling action of the connecting part, the pawl can move away from the locking bar to unlock or reset under the action of the torsion spring to re-engage with the locking bar. The torsion spring can ensure the normal engagement state between the pawl and the locking bar.

[0019] Furthermore, the top of the locking bar is provided with multiple locking teeth, and the bottom of the pawl is provided with multiple ratchet teeth that mesh with the locking teeth of the locking bar. The inclination direction of the locking teeth on the locking bar is consistent with the inclination direction of the ratchet teeth on the pawl.

[0020] In this design, the locking teeth of the locking bar are located at its top, and the ratchet teeth on the pawl are located at its bottom. This ensures a smooth locking engagement between the pawl and the locking bar. Furthermore, since the tilt direction of the locking teeth on the locking bar is the same as that of the ratchet teeth on the pawl, it ensures a one-way engagement between the pawl and the locking bar. The pawl can only move unidirectionally along the locking bar and cannot move backward, thus further ensuring that the retractable slider will not retract and further ensuring the stability of the entire device.

[0021] Furthermore, one end of the connector is fixedly connected to a fixed joint, which is connected to the ratchet, and the other end of the connector is fixedly connected to a connecting plate, which is connected to the hanger docking unit.

[0022] In this solution, the connector is connected to the pawl via a fixed joint and to the hanger docking unit via a connecting plate. The fixed joint and connecting plate provide connection points for the connector to connect to the pawl and hanger docking unit, making it easier to connect and fix.

[0023] Furthermore, the two ends of the bracket are respectively connected to a first roller and a second roller, one end of the connector is connected to the bracket docking unit, the connector passes around the first roller and the second roller in sequence, and the other end of the connector is connected to the locking device.

[0024] In this design, the first and second rollers provide support points for the connector, making the connector move more stably.

[0025] Furthermore, a tensioning wheel is provided between the first roller and the second roller, and both ends of the tensioning wheel are connected to the bracket. The connecting member passes around the first roller, the tensioning wheel and the second roller in sequence.

[0026] The tensioning wheel in this design further prevents the connector from slipping or becoming excessively loose, ensuring that the connector moves smoothly with the hanger docking unit.

[0027] Furthermore, the hanger docking unit includes a lower fork plate and a fixed section, the fixed section being connected to the lower fork plate; the fixed section is vertically slidably engaged with the hanger, one end of the connector is connected to the fixed section, and a docking hole is provided on the lower fork plate.

[0028] The hanger docking unit in this solution includes a lower fork plate and a fixed section. The docking holes on the lower fork plate facilitate connection and cooperation with existing docking devices in the future, while the fixed section facilitates vertical sliding cooperation with the hanger.

[0029] Furthermore, the bracket includes a sliding block, a first side plate, a second side plate, and two abutment plates. The first side plate and the second side plate are connected to each other. The two abutment plates are perpendicularly connected to the first side plate and the second side plate, respectively. The sliding block is perpendicularly connected between the first side plate and the second side plate and is located above the abutment plates. The fixing section is vertically slidingly engaged with the sliding block.

[0030] The baffle plate of this design can cooperate with the retractable slider to clamp the angle steel. The first side plate and the second side plate form an installation channel to facilitate the installation of the retractable slider and the locking and retraction unit. The fixed section and the sliding block achieve vertical sliding cooperation, thereby realizing the vertical sliding cooperation between the hanger docking unit and the hanger.

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0048] As an embodiment of this application, an anti-reverse mounting device is provided, which is used to dock with a docking device in the prior art. Specifically, after the docking device is connected to a drone, the docking device docks with the anti-reverse mounting device of this application. Then, the drone is used to hang the anti-reverse mounting device of this application and the fall arresting rope fixed on the device together on the angle steel at the top of the tower and lock them in place. This allows the fall arresting rope to act as a flexible guide rail, making it convenient for workers to climb the tower along the fall arresting rope later.

[0049] like Figures 1-2As shown in the figure, as an embodiment of this application, an anti-reverse mounting device is provided, including a mounting bracket docking unit 6 and a mounting bracket 7. The mounting bracket docking unit 6 and the mounting bracket 7 are vertically slidably engaged. In one embodiment, the mounting bracket 7 includes a sliding block 73, a first side plate 70, a second side plate 71, and two abutment plates 700. The first side plate 70 and the second side plate 71 are symmetrically arranged. The two abutment plates 700 are vertically fixedly connected to one end of the first side plate 70 and the second side plate 71, respectively. There is a gap between the first side plate 70 and the second side plate 71 to form a moving channel. The first side plate 70 and the second side plate 71 are fixedly connected by a shaft and screws. For example, a shaft is provided between the first side plate 70 and the second side plate 71. The two ends of the shaft are fixed to the first side plate 70 and the second side plate 71 by screws, thereby realizing the connection between the first side plate and the second side plate.

[0050] In one embodiment, two abutment plates 700 are integrally formed with the first side plate 70 and the second side plate 71, respectively, and an mounting ring 75 is connected between the two abutment plates 700. The mounting ring 75 is figure-eight shaped and is used to connect a fall arresting rope. One of the rings of the mounting ring 75 is suspended below the abutment plate 700, and the other ring of the mounting ring 75 is fixed to the lower part of the two abutment plates 700 by a shaft.

[0051] like Figure 1 , Figure 2 As shown, the two ends of the bracket 7 are the end point of clamping the tower and the starting point away from the tower, respectively. That is, the side closer to the stop plate 700 is the end point, and the side away from the stop plate 700 is the starting point.

[0052] One end of the sliding block 73 is located between the first side plate 70 and the second side plate 71 and is vertically fixedly connected to the first side plate 70 and the second side plate 71. The sliding block 73 can be fixedly connected to the first side plate 70 and the second side plate 71 by screws. The sliding block 73 and the abutment plate 700 are located on the same side, and the sliding block 73 is located above the abutment plate 700. The sliding block 73 and the abutment plate 700 are located on the end point side, that is, on the side close to the tower angle steel. The bracket docking unit 6 is vertically slidingly engaged with the sliding block 73.

[0053] In one embodiment, a guide plate 72 is fixedly connected to the side of the first side plate 70 and the second side plate 71 away from the abutment plate 700 by rivets, screws, or bolts. The guide plate 72 is inclined towards the side away from the abutment plate 700. Guide ropes 74 are respectively connected to the two sides of the guide plate 72 and the first side plate 70 and the second side plate 71 by rivets. The guide ropes 74 are inclined and are made of spring ropes or elastic ropes, which can deform to avoid interference with the angle steel when hanging on the tower. In this embodiment, the guide plate 72 and the guide ropes 74 can guide the bracket 7 when it is hung on the angle steel, so that the bracket 7 can be hung more accurately on the tower angle steel.

[0054] Combination Figure 2 and Figure 3 As shown, a retractable slider 76 for clamping the tower is horizontally slidably fitted on the bracket 7. When the retractable slider 76 slides to its end position, it can cooperate with one side of the bracket 7 to lock the tower. Specifically, the retractable slider 76 is U-shaped, and the U-shaped opening of the retractable slider 76 is set towards the abutment plate 700. In this way, the retractable slider 76 can be clamped on the angle steel of the tower and cooperate with the abutment plate 700 on one side of the bracket 7 to achieve the purpose of stably clamping and fixing it on the angle steel of the tower.

[0055] Combination Figure 4 and Figure 5 As shown, both the inner sides of the first side plate 70 and the second side plate 71 are horizontally provided with sliding grooves 762, which are combined with 5 and Figure 6 As shown, both sides of the retractable slider 76 are rotatably connected to sliding wheels 761. The sliding wheels 761 on both sides of the retractable slider 76 are located in the sliding grooves 762 of the first side plate 70 and the second side plate 71 respectively and slide in cooperation with the sliding grooves 762.

[0056] The hanger 7 is equipped with a drive member for driving the retractable slider 76 to slide, and a drive member for moving to the end position. The hanger 7 is also equipped with a locking retraction unit for limiting the retraction of the slider 76. In one embodiment, such as... Figure 7 and Figure 8 As shown, the driving component includes a coil spring 8 and a coil spring shaft 81. The two ends of the coil spring shaft 81 are rotatably connected to the two sides of the bracket 7, respectively. The coil spring shaft 81 is located on the side near the abutment plate 700, and the two ends of the coil spring shaft 81 are rotatably connected to the first side plate 70 and the second side plate 71 of the bracket 7, respectively. The connection method between the coil spring shaft 81 and the first side plate 70 and the second side plate 71 is existing technology, such as using a rotating shaft or bearing connection, which will not be described in detail here. The coil spring 8 is wound on the coil spring shaft 81, one end of the coil spring 8 is fixed on the coil spring shaft 81, and the other end of the coil spring 8 is fixedly connected to the retractable slider 76 by screws.

[0057] In one embodiment, such as Figure 2 and Figure 3 As shown, the locking and retraction unit includes a locking device 900 and a locking strip 90. The locking device 900 is fixed to the retractable slider 76, and the locking strip 90 is fixed to the bracket 7. The locking device 900 and the locking strip 90 can lock together. A connector 79 is connected to the bracket docking unit 6. The other end of the connector 79 is connected to the retractable slider 76. Specifically, in this embodiment, the end of the connector 79 away from the bracket docking unit 6 is connected to the locking device 900. Since the locking device 900 is fixed to the retractable slider 76, connecting one end of the connector 79 to the locking device 900 indirectly achieves connection with the retractable slider 76. The movement of the connector 79 can cause the locking device 900 and the locking strip 90 to unlock or lock together.

[0058] When the hanger docking unit 6 slides upward, the connector 79 drives the locking device and locking bar 90 to unlock, and at this time the connector 79 can drive the retractable slider 76 to move to the starting position; when the hanger docking unit 6 slides downward to reset, the connector 79 drives the locking device 900 to lock with the locking bar 90, and at this time the drive can drive the retractable slider 76 to move to the end position. During the process of the retractable slider 76 moving to the end position, it can drive the locking device 900 to move unidirectionally along the locking bar 90.

[0059] In one embodiment, combined Figure 2 and Figure 3 As shown, the locking device 900 includes a mounting part 901 and a pawl 902. The mounting part 901 is fixedly connected to the retractable slider 76 by screws. Rotating plates 903 are fixedly connected to both sides of the pawl 902. In this embodiment, the rotating plates 903 are integrally formed with one side of the pawl 902. The two rotating plates 903 are rotatably connected to both sides of the mounting part 901 respectively. An elastic element is provided between the pawl 902 and the mounting part 901. One end of the connecting part 79 is fixedly connected to the pawl 902. The pawl 902 and the locking bar 90 can engage or disengage with each other, combining... Figure 3 and Figure 6 As shown, in this embodiment, one end of the connector 79 is fixedly connected to a fixed connector 906, which is fixed to the pawl 902 by screws or welding, thereby realizing the connection between the connector 79 and the pawl 902. The other end of the connector 79 is fixedly connected to a connecting plate 791, which is connected to the hanger docking unit 6.

[0060] In one embodiment, combined Figure 4 and Figure 5 As shown, the elastic element is a torsion spring 905. A connecting shaft 904 is provided between the rotating plate 903 and the mounting part 901. The rotating plate 903 and the mounting part 901 are rotatably connected through the connecting shaft 904. The torsion spring 905 is sleeved on the connecting shaft 904, and both ends of the torsion spring 905 are fixed to the mounting part 901 and the pawl 902, respectively. Specifically, in one embodiment, the torsion spring 905 is installed between one of the rotating plates 903 and the mounting part 901. A torsion spring mounting hole is provided on the side of the pawl 902 facing the mounting part 901, and a torsion spring limiting groove is provided on the side of the mounting part 901. The torsion spring 905 passes through the connecting shaft 904 between the rotating plate 903 and the mounting part 901, with one end of the torsion spring 905 inserted into the torsion spring mounting hole on the pawl 902, and the other end of the torsion spring 905 located in the torsion spring limiting groove on the side of the mounting part 901, thereby realizing the installation limiting of the torsion spring 905.

[0061] like Figure 3 , Figure 9 and Figure 10As shown, the locking teeth of both locking bars 90 are located at their tops. The bottom end of the pawl 902 is provided with multiple ratchet teeth that mesh with the locking teeth on the locking bars 90. The tilt direction of the locking teeth on the locking bars 90 is consistent with the tilt direction of the ratchet teeth on the pawl 902, so that the pawl can only slide unidirectionally along the locking bars 90. In this application, the pawl 902 can only move unidirectionally along the locking bars 90 towards the stop plate 700, and cannot move in the opposite direction on the locking bars 90 away from the stop plate 700, thereby preventing backward movement.

[0062] When the hanger docking unit 6 slides upward, the connector 79 pulls the pawl 902 away from the locking bar 90, thus separating the pawl 902 from the locking bar 90. At this time, the locking device 900 and the locking bar 90 are unlocked, allowing the connector 79 to pull the retractable slider 76 to the starting position as the hanger docking unit 6 continues to move upward. At this time, the retractable slider 76 opens to a large extent, facilitating the subsequent mounting of pole angle steel of different sizes. When the hanger docking unit 6 slides downward to reset, the connector... When component 79 loosens and resets, the pawl 902 engages with the locking bar 90, thus returning to the locked state. Simultaneously, the coil spring 8 pulls the retractable slider 76 towards the end point, engaging with the abutment plate 700 to lock it onto the tower angle steel. During the process of the coil spring 8 pulling the retractable slider 76, the pawl 902, under the action of the torsion spring 905, can move along the locking bar 90 towards the abutment plate 700. After locking the tower angle steel, the pawl 902 can lock with the locking bar 90 and cannot move backward, thereby effectively improving safety.

[0063] In one embodiment, such as Figure 2 and Figure 6 As shown, the two ends of the hanger 7 are respectively connected to a first roller 77 and a second roller 78. The two ends of the first roller 77 and the second roller 78 are rotatably connected to the first side plate 70 and the second side plate 71 of the hanger 7, respectively. The first roller 77 and the second roller 78 are located at the end point and the start point of the hanger 7, respectively. In this embodiment, the connector 79 is a pull rope, and in another embodiment, the connector 79 is a stainless steel cable.

[0064] One end of the connector 79 is connected to the bracket docking unit 6. The connector 79 passes sequentially around the first roller 77 and the second roller 78, and the other end of the connector 79 is connected to the locking device. Figure 6 As shown, the other end of the connector 79 is fixed to the pawl 902 on the lock by screws via the fastener 906.

[0065] In another embodiment, such as Figure 2 and Figure 6As shown, a tensioning wheel 771 is provided between the first roller 77 and the second roller 78. The two ends of the tensioning wheel 771 are rotatably connected to the bracket 7. The connecting piece 79 passes around the first roller 77, the tensioning wheel 771 and the second roller 78 in sequence.

[0066] In one embodiment, combined Figure 1 , Figure 2 As shown, the hanger docking unit 6 includes a lower fork plate 60 and a fixing section 64. The fixing section 64 is connected to the lower fork plate 60. The lower fork plate 60 has an inverted V-shaped structure, which gives it two symmetrical forked rods. The tops of the two forked rods of the lower fork plate 60 are connected to multi-colored visual recognition balls 65 by screws, such as foam balls in combinations of yellow, red, blue and orange. These balls are eye-catching and help the UAV control system quickly identify and find the docking position when the lower fork plate 60 docks with the docking device.

[0067] Fixed section 64 and bracket 7 slide vertically together, such as Figure 6 As shown, one end of the connector 79 is connected to the fixed section 64, and a connecting plate 791 is fixedly connected to the end of the connector 79. The lower part of the fixed section 64 and the connecting plate 791 are provided with round holes. After the round hole of the connecting plate 791 at the end of the connector 79 overlaps with the round hole of the fixed section 64, it is fixed by bolts or screws, thereby achieving the purpose of fixing the connector 79 to the fixed section 64.

[0068] The sliding block 73 on the hanger 7 has a vertical through groove inside. The fixing section 64 is inserted into the through groove inside the sliding block 73 on the hanger 7 and can slide vertically along the sliding block 73. So when the docking device docks with the lower fork plate 60 and is lifted upward, the entire hanger docking unit 6 will slide upward. Since the fixing section 64 of the hanger docking unit 6 is connected to the connector 79, the upward sliding distance of the entire hanger docking unit 6 will be limited by the connector 79 and the retractable slider 76, and will not detach from the hanger 7.

[0069] like Figure 1 As shown, a docking hole 62 is provided on the lower fork plate 60. The docking hole 62 is located at the lower part of the lower fork plate 60 and is a horizontally arranged waist-shaped hole. A docking opening 61 is provided at the top of the intersection of the lower parts of the two forks of the lower fork plate 60. The docking opening 61 is U-shaped. The setting of the docking opening 61 facilitates the docking and cooperation with the docking device in the later stage.

[0070] In one embodiment, the fixing section 64 is fixedly connected to the lower fork plate 60, and the top end of the fixing section 64 is integrally connected to the lower fork plate 60 or fixed by screws or other means; in another embodiment, the fixing section 64 and the lower fork plate 60 are detachably connected, such as by a snap-fit ​​connection.

[0071] In use, first connect the docking device and the drone on the ground, and then connect the hanger docking unit 6 to the docking device.

[0072] Then, the pilot controls the drone to take off. As the drone moves the docking device and the anti-reverse mounting device connected to the docking device upward, the hanger 7 will slide downward relative to the hanger docking unit 6 under its own gravity. At this time, the hanger docking unit 6 is in an upward sliding state relative to the hanger 7, which will tighten the connecting piece 79 connected to it. At the same time, the connecting piece 79 will drive the pawl 902 to rotate upward, thereby unlocking the pawl 902 from the locking bar 90. As the hanger docking unit 6 continues to move upward, the connecting piece 79 can pull the retractable slider 76 to the starting position. At this time, the retractable slider 76 opens to a large extent, which makes it easier to hang on poles of different sizes later.

[0073] The drone transports the entire device to the top of the transmission tower's mounting point. By capturing images and adjusting its position and orientation, it aligns with the angle steel at the tower's mounting point and descends vertically, gradually approaching the angle steel. The guide plate 72 on the mounting bracket 7 allows the angle steel to slide into the locking range between the stop plate 700 and the guide plate 72. The guide rope 74 then allows the angle steel to slide into one side of the stop plate 700. At this point, the mounting bracket docking unit 6 slides downwards to reset, causing the connector 79 to loosen. The connector 79 then releases its tension on the pawl 902, which resets under the action of the torsion spring 905 and re-locks with the locking strip 90. Simultaneously, the coil spring 8 pulls the retractable slider 76 towards the end position to clamp the angle steel of the tower, thus fixing the mounting bracket 7 to the tower's angle steel. Because the retractable slider 76 can slide to both the end and start positions, it can accommodate angle steels of different widths, making it more versatile.

[0074] like Figure 10 As shown, during the movement of the retractable slider 76 toward the end position, it can drive the pawl 902 to move unidirectionally along the locking bar 90. When the retractable slider 76 moves to the end position and clamps the tower angle steel together with the baffle plate 700, the retractable slider 76 stops moving. At this time, the pawl 902 also stops moving. Therefore, when the retractable slider 76 clamps the tower, the pawl 902 and the locking bar 90 produce a locking effect.

[0075] Since the connecting unit 6 of the hanger is not tightened at this time, the connecting part 79 is in a loose state. At this time, the pawl 902 is locked with the locking strip 90 under the action of the torsion spring 905. At this time, the pawl 902 will not move in the opposite direction, ensuring that the retractable slider 76 will not retract, thereby strengthening the stability of the connection between the retractable slider 76 and the tower. This avoids the entire hanger device from shaking and tilting or the retractable slider from retracting due to sudden and continuous force caused by personnel falling during operation, thus preventing personnel from falling and improving work safety.

[0076] After the pilot confirms the mounting device is in place by capturing footage, the pilot controls the separation of the docking device from the mounting device of this application.

[0077] The drone is then brought back, allowing staff to climb the tower using safety ropes.

[0078] When the tower climbing operation is completed and the mounting device needs to be removed, a drone is used to carry the docking device to the top of the mounting device, and the docking device is docked with the mounting device in the air.

[0079] Then, the drone is controlled to fly upward, which causes the fixed section 64 in the mounting docking unit 6 to slide upward, thereby causing the connector 79 to tighten. At this time, the connector 79 will pull the pawl 902 to rotate away from the locking bar 90, thus unlocking the pawl 902 from the locking bar 90. As the fixed section 64 continues to slide upward, it can drive the entire retractable slider 76 to move towards the starting position and away from the loose angle steel. In this way, the drone can take the entire docking device and mounting device away and remove the mounting device from the angle steel. Finally, the drone flies back and brings the mounting device back to the ground.
