In traditional operations, workers need to use anti-fall devices to assist in climbing the tower to perform high-altitude operations. For example, the existing anti-fall devices, such as the typical traditional tower anti-fall devices, are usually composed of foot spikes, safety belts, and anti-fall hooks. In actual use, they have obvious defects: First, the installation process is complicated and requires manual installation step by step, which limits the climbing speed and takes a long time to install; second, the anti-fall device structure has the phenomenon of retreat and shaking, which affects the stability of use; third, the installation of the anti-fall device itself carries the risk of falling from a high altitude; fourth, it can only be applied to a single tower type and cannot adapt to composite tower types, such as towers with insulator string structures, so it lacks versatility; fifth, the operation process is cumbersome, and the anti-fall safety belt and anti-fall hook need to be used alternately during the tower climbing process.

[0017] Furthermore, the vehicle mounting unit includes a mounting plate and a connecting block, the mounting plate is connected to the body of the drone, the connecting block is connected to the connecting unit, and the connecting block is detachably connected to the mounting plate.

[0018] Compared with the prior art, this application has the following advantages and beneficial effects: 1. The docking assembly and the mounting assembly in this application are detachably connected, so that after the drone is connected to the docking assembly, the mounting assembly can be moved to the position of the pole tower to be hung for inspection. After the mounting assembly is successfully installed at the pole tower hanging point, the docking assembly and the mounting assembly can be separated to remove the docking assembly from the mounting assembly. When the mounting assembly needs to be removed from the pole tower, the docking assembly and the mounting assembly are connected again, and the mounting assembly can be removed by the drone. The mounting assembly in this application includes a rack docking unit and a rack. The rack docking unit can be connected to the docking assembly, and the rack is used to hang on the pole tower and fix it to the pole tower. By connecting the anti-fall rope to the rack, the anti-fall rope can be installed on the pole tower after the rack is fixed on the pole tower, which makes it convenient for the later operators to connect the anti-fall device on the safety belt to the anti-fall rope to perform tower climbing operations.

[0019] In the present application, a retractable slider slides horizontally on the bracket, and a driving member drives the retractable slider to move. When the bracket is hung on the pole tower, the retractable slider is driven to move toward the end position of the bracket so that the retractable slider is clamped and fixed on the pole tower, ensuring the stability of the entire mounting assembly after installation.

[0020] The locking mechanism is configured to lock the cam and release the latch, and the latch is configured to lock the cam and release the latch, so that the cam is locked and released, and the cam is released when the cam is unlocked. When the drone moves the entire device to the hanging point position of the pole tower, it slowly lowers the entire device until the bracket in the mounting assembly falls on the angle steel of the pole tower. At this time, the bracket docking unit slides downward and resets. At this time, the connecting piece is loose, and the connecting piece drives the lock and the locking strip to be locked again. The retractable slider can be pulled to the end position by the driving piece to clamp the angle steel of the pole tower, thereby fixing the bracket and the angle steel of the pole tower. After the bracket and the angle steel of the pole tower are fixed, the drone and the docking assembly will leave the mounting assembly. At this time, the bracket docking unit in the mounting assembly is in the reset state, and the bracket docking unit does not tighten the connecting piece. At this time, the lock and the locking strip are in the locked state, and the retractable slider can be pulled to the end position to clamp the angle steel of the pole tower, thereby fixing the bracket and the angle steel of the pole tower. During the movement of the point, the lock can be driven to move unidirectionally along the locking strip. When the retracting slider moves to the end position and clamps the pole tower angle steel, the retracting slider no longer moves, and the lock also no longer moves at this time. Since the lock moves unidirectionally along the locking strip, when the retracting slider clamps the pole tower, the lock and the locking strip produce a locking effect, and at this time the lock will not move in the opposite direction, ensuring that the retracting slider will not retreat, thereby strengthening the stability of the connection between the retracting slider and the pole tower, and avoiding the entire mounting assembly from shaking and falling due to sudden and continuous force caused by personnel falling during operation, and the retracting slider retreating, thereby avoiding situations where personnel fall, thereby improving operation safety.

[0021] When the entire mounting assembly needs to be removed, the drone drives the docking assembly to connect with the rack docking unit and then lifts the rack docking unit upward. At this time, the connecting piece on the rack docking unit will be tightened, and the locker and the locking bar will be driven to unlock. At this time, the connecting piece will pull the retracting slider to the starting position, thereby releasing the retracting slider from the pole tower, making it easier for the drone to remove the entire device from the pole tower.

[0022] The installation process in this application is simple. The mounting assembly can be moved to the pole tower hanging point position by a drone. The vertical displacement of the bracket docking unit in the mounting assembly is used to drive the locking device and the locking strip to unlock or lock the connecting member, and the driving member drives the retracting slider to move to fix the entire mounting assembly on the pole tower. The entire operation is simple and does not require manual installation, which effectively improves the installation efficiency and safety of the operation. When climbing the tower, it is only necessary to connect the anti-fall device on the worker's safety belt with the anti-fall rope hanging on the mounting assembly to climb the tower. There is no need to use an anti-fall hook when climbing the tower. The use of the device in this application makes the tower climbing process simpler. In addition, the cooperation of the locker and the locking strip in this application can improve the stability of the installation of the entire mounting assembly on the pole tower, avoid the retraction of the retracting slider and the shaking of the entire mounting device, and make it safer to use.

[0023] 2. The distance between the retractable slider and the end position in this application can be adjusted according to the size of different tower types, and can be applied to tower angle steels of different tower types, with greater versatility.

[0024] 3. In the lock device of the present application, when the return spring is in the reset state, the anti-return block expands outward and locks with the locking bar, thereby preventing the retraction slider from retreating; and when the connecting member pulls the push rod toward the starting position and compresses the return spring, the driving block at the bottom of the push block on the connecting rod will slide in the inclined slot of the anti-return block and drive the anti-return block to retract inward and unlock with the locking bar, thereby making it easier for the connecting member to pull the retraction slider toward the starting position and away from the angle steel of the pole tower. At this time, it is convenient to remove the mounting assembly from the angle steel of the pole tower after the tower climbing operation is no longer required; the present application also provides another lock structure, that is, the cooperation of the pawl and the lock rack, which can also achieve the unlocking and locking state with the locking bar, thereby achieving the function of locking or loosening the angle steel.

[0025] 4. The anti-retraction block or pawl in the locker of this application is engaged with the locking strip through the locking teeth, which can improve the locking effect between the anti-retraction block and the locking strip, and further prevent the retracted slider from retreating.

[0026] 5. The driving part that drives the retraction slider to move in this application includes a coil spring and a coil spring shaft. The coil spring realizes a linkage effect with the connecting part and the bracket docking unit. When the bracket docking unit slides upward and drives the connecting part to tighten and pull the retraction slider to move toward the starting position, the coil spring is stretched; and when the bracket docking unit slides downward and causes the connecting part to loosen and expand, the coil spring will pull the retraction slider to move to the end position and clamp it on the pole tower angle steel.

[0027] 6. In the rack docking unit of the present application, the lower fork plate and the fixed section are detachably connected via an upper quick-release box and a lower quick-release box, thereby reducing the overall volume and facilitating storage and transportation.

[0028] 7. The connection unit in the docking assembly in this application is connected to the drone through a vehicle mounting unit, and the vehicle mounting unit includes a mounting plate and a connecting block that are detachably connected to each other, which facilitates the detachable connection between the entire docking assembly and the drone, making installation and use more convenient and quick.

In one embodiment, the end of the push rod 92 away from the push block 94 is fixedly connected to a connector 93, and a fixing groove is formed on one side of the connector 93. One end of the connecting member 79 is inserted into the fixing groove and fixed in the fixing groove by a screw. A return spring 95 is sleeved on the outer side of the push rod 92. The two ends of the return spring 95 are respectively abutted or connected to the fixed block 91 and the push block 94. The bottom of the push block 94 is connected to a driving block (not shown in the figure). The driving block is located in a slot 97. There are two driving blocks at the bottom of the push block 94. The two driving blocks are respectively located in the slots 97 of the two anti-retraction blocks 96. When the reset spring 95 is in the reset state (that is, when the drone drives the bracket docking unit 6 downward to rest on the pole tower angle steel 100, the bracket docking unit 6 slides downward to the reset state. At this time, the bracket docking unit 6 has not tightened the connecting piece 79, and the connecting piece 79 is in a loose state. The push rod 92 is not subjected to the tension of the connecting piece 79, and the reset spring 95 will reset). Under the action of the reset spring 95, the driving block slides along the slot 97 away from the fixed block 91 and drives the anti-retraction block 96 to expand outward and lock with the locking bar 90 to prevent the retreat phenomenon, thereby facilitating the stable fixation of the entire mounting assembly on the pole tower angle steel 100.

[0041] When the retracting slider 76 stops moving, the anti-retraction block 96 expands outward under the action of the return spring 95 and locks with the locking bar 90 again, thereby preventing the retracting slider 76 from retreating, thereby improving the stable installation of the entire mounting assembly and avoiding the risk of falling of the operator during operation.

[0042] When the rack docking unit 6 slides upward (that is, the drone drives it to lift up), the connecting piece 79 on the rack docking unit 6 will be tightened. At this time, the connecting piece 79 pulls the push rod 92 toward the starting position. At this time, the return spring 95 is compressed, and the drive block slides in the slot 97 to drive the anti-retraction block 96 to retract inward and unlock the locking strip 90. At this time, as the connecting piece 79 is gradually tightened by the rack docking unit 6, it will drive the retraction slider 76 to move toward the starting position and away from the end position, so that the retraction slider 76 can maintain the maximum distance from the end position when installing the mounting component, so as to adapt to pole tower angle steels 100 of different sizes and specifications, and to facilitate loosening the angle steel 100 and removing it smoothly when disassembling the mounting component.

[0043] In one embodiment, the anti-retraction block 96 and / or the locking strip 90 are connected to the inner side of a non-slip rubber strip. When the anti-retraction block 96 is opened outward and abuts against the locking strip 90, the anti-retraction block 96 and the locking strip 90 are locked by friction. In another embodiment, Figure 7 As shown, the locking bar 90 and the anti-retreat block 96 are provided with a plurality of mutually meshing locking teeth on the side facing each other. The locking teeth on the two locking bars 90 are one-way bevel teeth, similar to the ratchet teeth. The locking teeth on the anti-retreat block 96 match the locking teeth on the locking bar 90. The anti-retreat block 96 can be engaged and locked with the locking bar 90 when expanded outward. In this embodiment, the anti-retreat block 96 and the locking bar 90 are engaged and clamped by the locking teeth, which can improve the locking effect of the two. Moreover, the locking teeth are one-way bevel teeth, and the anti-retreat block 96 and the locking bar 90 can only move in one direction after being engaged with each other.

[0044] When the locking cam 96 is in the state of being compressed, the locking cam 96 is in a state of being compressed, and the locking cam 96 is in a state of being compressed, so that the locking cam 96 can be compressed and the locking cam 96 is in a state of being compressed.

[0045] In one embodiment, Figure 3 and Figure 4As shown, the two ends of the hanger 7 are respectively connected to the first roller 77 and the second roller 78, and the two ends of the first roller 77 and the second roller 78 are respectively rotatably connected to the first side plate 70 and the second side plate 71 of the hanger 7, and the first roller 77 and the second roller 78 are respectively located at the end position and the starting position of the hanger 7. In this embodiment, the connecting member 79 is a pull rope, and in another embodiment, the connecting member 79 is a stainless steel cable.

[0046] One end of the connecting member 79 is connected to the rack docking unit 6, the connecting member 79 passes around the first roller 77 and the second roller 78 in sequence, and the other end of the connecting member 79 is connected to the locker, as shown in FIG. Figure 7 As shown, the other end of the connecting member 79 is connected to the connecting head 93 at one end of the push rod 92 on the lock 900.

[0047] In another embodiment, Figure 8 and Figure 9 As shown, the lock 100 includes a mounting member 901 and a pawl 902, and the mounting member 901 is fixedly connected to the retracting slider 76 by screws; rotating plates 903 are fixedly connected to both sides of the pawl 902. In this embodiment, the rotating plate 903 and one side of the pawl 902 are integrally formed, and the two rotating plates 903 are respectively rotatably connected to the two sides of the mounting member 901, and an elastic member is provided between the pawl 902 and the mounting member 901; one end of the connecting member 79 is fixedly connected to the pawl 902, and the pawl 902 and the locking strip 90 can engage with or separate from each other. In this embodiment, one end of the connecting member 79 is fixedly connected to a fixing joint 906, and the fixing joint 906 is fixed to the pawl 902 by screws or welding, thereby realizing the connection between the connecting member 79 and the pawl 902.

[0048] In one embodiment, combined Figure 10 and Figure 11 As shown, the elastic member is a torsion spring 905, and a connecting shaft 904 is provided between the rotating plate 903 and the mounting member 901. The rotating plate 903 and the mounting member 901 are rotatably connected through the connecting shaft 904. The torsion spring 905 is sleeved on the connecting shaft 904 and the two ends of the torsion spring 905 are respectively fixed to the mounting member 901 and the pawl 902. Specifically: in one embodiment, the torsion spring 905 is installed between one of the rotating plates 903 and the mounting member 901, a torsion spring mounting hole is provided on the side of the pawl 902 facing the mounting member 901, and a torsion spring limiting groove is provided on one side of the mounting member 901. The torsion spring 905 is passed through the connecting shaft 904 between the rotating plate 903 and the mounting member 901, and one end of the torsion spring 905 is inserted into the torsion spring mounting hole on the pawl 902, and the other end of the torsion spring 905 is located in the torsion spring limiting groove on one side of the mounting member 901, thereby realizing the installation limitation of the torsion spring 905.

[0049] like Figure 9As shown, the lock teeth of the two locking bars 90 are both located at the top thereof, and the bottom end of the pawl 902 is provided with a plurality of ratchets that engage with the lock teeth on the locking bar 90. The inclination direction of the lock teeth on the locking bar 90 is consistent with the inclination direction of the ratchet teeth on the pawl 902, so that the pawl can only slide unidirectionally along the locking bar 90. In this application, the pawl 902 can only move unidirectionally along the locking bar 90 toward the stop plate 700, and cannot move in the opposite direction on the locking bar 90 away from the stop plate 700, thereby preventing retreat.

[0050] When the bracket docking unit 6 slides upward, the connecting piece 79 can pull the pawl 902 away from the locking bar 90, thereby separating the pawl 902 from the locking bar 90. At this time, the lock 900 and the locking bar 90 are unlocked, so that the connecting piece 79 can pull the retracting slider 76 to the starting position during the continuous upward movement of the bracket docking unit 6. At this time, the retracting slider 76 is opened to a large extent, which is convenient for later mounting on pole tower angle steels of different sizes; and when the bracket docking unit 6 slides downward to reset, the connecting piece 79 can be Component 79 is loosened and reset, and the pawl 902 is engaged with the locking bar 90 and is in the locked state again. At the same time, the coil spring 8 will pull the retracting slider 76 to the end point and cooperate with the abutment plate 700 to lock it on the pole tower angle steel. In the process of the coil spring 8 pulling the retracting slider 76, the pawl 902 can move along the locking bar 90 toward the abutment plate 700 under the action of the torsion spring 905. After locking the pole tower angle steel, the pawl 902 can be locked with the locking bar 90 and cannot move backward, thereby effectively improving the safety effect.

[0051] In one embodiment, combined Figure 2 、 Figure 4 and Figure 6 As shown, the hanger docking unit 6 includes a lower fork plate 60 and a fixed section 64, the fixed section 64 is connected to the lower fork plate 60, and the lower fork plate 60 is detachably connected to the docking assembly. The lower fork plate 60 is in an inverted eight-shaped structure, so that the lower fork plate 60 has two symmetrical forked rods, and the tops of the two forked rods of the lower fork plate 60 are connected by screws with multi-color visual identification balls 65, such as foam balls in a combination of yellow, red, blue and orange, which are more eye-catching and are conducive to the UAV control system to quickly identify and find the docking position when the lower fork plate 60 and the docking assembly are docked later.

[0052] The fixing section 64 is vertically slidably matched with the hanger 7, one end of the connecting piece 79 is connected to the fixing section 64, and the end of the connecting piece 79 is fixedly connected to a mounting head. Circular holes are provided on the lower part of the fixing section 64 and the mounting head. After the circular hole of the mounting head at the end of the connecting piece 79 overlaps with the circular hole of the fixing section 64, it is fixed by bolts, thereby achieving the purpose of fixing the connecting piece 79 on the fixing section 64.

[0053] A through slot is vertically provided inside the sliding block 73 on the hanger 7, and the fixed section 64 is inserted into the through slot inside the sliding block 73 on the hanger 7 and can slide vertically along the sliding block 73. In this way, when the docking assembly is docked with the lower fork plate 60 and lifted upward, the entire hanger docking unit 6 will slide upward. Since the fixed section 64 of the hanger docking unit 6 is connected to the connecting piece 79, the overall upward sliding distance of the hanger docking unit 6 will be limited by the connecting piece 79 and the retracting slider 76, and will not detach from the hanger 7.

[0054] like Figure 2 As shown, a docking hole 62 is provided on the lower fork plate 60, and the docking hole 62 is located at the lower part of the lower fork plate 60, and the docking hole 62 is a waist-shaped hole set horizontally. A docking opening 61 is provided at the top where the lower part of the two forked rods of the lower fork plate 60 intersects, and the docking opening 61 is U-shaped. The setting of the docking opening 61 facilitates docking with the docking assembly.

[0055] In one embodiment, the fixing section 64 is fixedly connected to the lower fork plate 60, and the top 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 is detachably connected to the lower fork plate 60, and the fixing section 64 is detachably connected to the lower fork plate 60. Figure 6 、 Figure 12 、 Figure 13 and Figure 14 As shown, a connecting seat 63 is connected between the fixing section 64 and the lower fork plate 60, and the connecting seat 63 includes an upper quick-release box 631 and a lower quick-release box 635. Figure 13 and Figure 14 As shown, the lower fork plate 60 is fixedly connected to the upper quick release box 631, and the lower portion of the lower fork plate 60 penetrates into the upper quick release box 631 and is fixedly connected to the upper quick release box 631 by screws; like Figure 12 As shown, the fixing section 64 is fixedly connected to the lower quick-release box 635. The fixing section 64 is T-shaped, and the top of the fixing section 64 is fixedly connected to the bottom of the lower quick-release box 635 by screws. The upper quick release box 631 and the lower quick release box 635 are detachably connected. Figure 13 and Figure 14 As shown, a notch is provided at the bottom of the upper quick release box 631 for the fixing section 64 to pass through. When the upper quick release box 631 and the lower quick release box 635 are engaged with each other, the top of the fixing section 64 can be inserted into the upper quick release box 631 through the notch.

[0056] like Figure 12 As shown, both sides of the lower quick-release box 635 are fixedly connected with a clamping block 636, the clamping block 636 is located above the fixed section 64, and the clamping block 636 is provided with a clamping hole; like Figure 13 and Figure 14As shown, a spring seat 632 is fixedly connected to the interior of the upper quick release box 631. The spring seat 632 is centrally located and is integrally formed with the upper quick release box 631 or fixed with screws or other means. Quick release buckles 633 are fitted on both sides of the upper quick release box 631 for horizontal sliding engagement. One end of the quick release buckle 633 passes through the upper quick release box 631, and a compression spring 634 is connected between the other end of the quick release buckle 633 and the spring seat 632. A hook 6331 is vertically connected to the inside of the quick release buckle 633. The hook 6331 is integrally formed with the quick release buckle 633 and is L-shaped. The hooks 6331 on both sides are symmetrical to each other. The two quick-release buckles 633 can be locked in the locking holes of the locking blocks 636 on the lower quick-release box 635. After the upper quick-release box 631 and the lower quick-release box 635 are buckled together, the two locking blocks 636 on the lower quick-release box 635 are located inside the upper quick-release box 631. Pressing the two quick-release buckles 633 inward can make the two hooks 6331 move away from the two locking holes. At this time, the hooks 6331 are not locked with the locking blocks 636, making it easy to separate and disassemble the lower quick-release box 635 and the upper quick-release box 631.

[0057] When connecting the lower fork plate 60 and the fixed joint 64, the two quick-release buckles 633 are pressed inward to prevent the quick-release buckles 633 from obstructing the block 636 on the lower quick-release box 635 from entering the upper quick-release box 631. At this time, the compression spring 634 is compressed and energy is stored; then the lower quick-release box 635 is fastened to the upper quick-release box 631, and then the two quick-release buckles 633 are released. At this time, the quick-release buckle 633 is reset under the action of the compression spring 634, and the hook 6331 on the quick-release buckle 633 is locked into the hole on the block 636 to achieve locking, thereby completing the quick connection of the lower fork plate 60 and the fixed joint 64.

[0058] The lower fork plate 60 and the fixing section 64 are detachably connected, so that they can be disassembled during transportation or storage, reducing the overall volume and making it easier to sell. The assembly is also quick and easy, and the operation is convenient.

[0059] In one embodiment, combined Figure 1 and Figure 15 As shown, the docking assembly includes a connecting unit 4 and a lock body docking unit 5. The bottom end of the connecting unit 4 is connected to the lock body docking unit 5, and the top end of the connecting unit 4 is connected to the vehicle mounting unit 2 connected to the body of the drone 1; In one embodiment, the connecting unit 4 includes multiple sections of flexible connecting pipes 41, Figure 16As shown, two adjacent sections of flexible connecting tubes 41 are connected by an articulated joint 43, and the articulated joint 43 is a universal joint. In this way, when the drone 1 drives the docking assembly to move, the multiple flexible connecting tubes 41 are flexibly connected to each other, which is convenient for adjusting the posture and facilitating smooth docking with the mounting assembly. At the same time, the multiple sections of flexible connecting tubes 41 can determine whether the lock body docking unit 5 in the docking assembly is docked with the mounting assembly. When the two are docked, the drone continues to descend. Since the docked lock body docking unit 5 and the mounting assembly will not descend with it, obvious bending will occur between the multiple sections of flexible connecting tubes, thereby producing a prompt effect of successful docking.

[0060] In one embodiment, the connecting unit 4 is coaxially fixedly connected to the lock body docking unit 5, such as Figure 15 As shown, in another embodiment, the connecting unit 4 is detachably connected to the lock body docking unit 5, and the top of the lock body docking unit 5 is connected to a quick-release connecting tube 42 by screws. The quick-release connecting tube 42 is detachably connected to the flexible connecting tube 41 at the bottom. Specifically, a quick-release joint 44 is connected between the quick-release connecting tube 42 and the flexible connecting tube 41 at the bottom. Figure 17 As shown, the quick-release joint 44 includes an upper joint 441, a lower joint 442 and a nut ring 443. The upper joint 441 is fixed to the lower part of the flexible connecting tube 41 by rivets, and the lower joint 442 is fixed to the upper part of the quick-release connecting tube 42 by rivets. The nut ring 443 is located on the outside of the upper joint 441 and is threadedly connected to the upper joint 441; a protrusion is provided at the bottom of the upper joint 441, and a groove is provided at the top of the lower joint 442. When the flexible connecting tube 41 and the quick-release connecting tube 42 are aligned and connected, the protrusion of the upper joint 441 is inserted into the groove of the lower joint 442, and the nut ring 443 is threadedly connected to the lower joint 442 by screwing the nut ring 443. In this way, the nut ring 443 threadably connects the lower joint 442 and the upper joint 441 together, realizing a detachable connection between the quick-release connecting tube 42 and the flexible connecting tube 41.

[0061] In this embodiment, the quick-release connecting tube 42 and the flexible connecting tube 41 are detachably connected, so that the connecting unit 4 and the lock body docking unit 5 form two independent parts, so that the two can be disassembled during transportation and storage to reduce the volume.

[0062] In one embodiment, combined Figure 18 、 Figure 19 and Figure 20 As shown, the vehicle mounting unit 2 includes a mounting plate 21 and a connecting block 26.

The mounting plate 21 is connected to the body of the drone 1 by screws through the four connecting columns 22. The other side of the mounting plate 21 is fixedly connected to two mounting blocks 23. The two mounting blocks 23 are symmetrically arranged, and a slot 24 is provided on the side of the two mounting blocks 23 facing each other. The two sides of the connecting block 26 can be respectively inserted into the two slots 24; one end of the slot 24 passes through the mounting block 23, and the other end of the slot 24 does not pass through the mounting block 23, that is, the other end of the slot 24 is a closed end, which facilitates the positioning of the connecting block 26 inserted into the slot 24.

[0063] A limiting post 25 is vertically connected to one side of the mounting block 23, and the limiting post 25 is threadedly connected to the mounting block 23. Figure 20 As shown, there are bayonet holes on both sides of the connecting block 26 corresponding to the positions of the limit columns 25. When the two sides of the connecting block 26 are respectively inserted into the slots 24 of the two mounting blocks 23, the limit columns 25 are tightened so that the limit columns 25 are inserted into the bayonet holes on both sides of the connecting block 26, thereby further locking and fixing the connecting block 26, thereby facilitating improving the stable connection between the entire docking assembly and the body of the drone 1.

[0064] In one embodiment, Figure 21 、 Figure 22 As shown, the lock body docking unit 5 includes a box body 50 and an upper fork plate 51. The upper fork plate 51 is connected to the box body 50 and has an "eight"-shaped structure, so that the upper fork plate 51 has two symmetrical bifurcated rods. A cylindrical counterweight column 53 is installed at the bottom of the two bifurcated rods of the upper fork plate 51. The counterweight column 53 helps maintain balance when the "eight"-shaped upper fork plate 51 and the lower fork plate 60 are docked. A docking groove 52 is defined in the center of the upper fork plate 51, and the lower fork plate 60 can be inserted into the docking groove 52.

[0065] The box body 50 is connected to the connecting unit 4, and the top of the box body 50 is connected to the quick-release connecting tube 42 through screws, and is connected to the flexible connecting tube 41 through the quick-release connecting tube 42. Figure 22As shown, the box body 50 includes a left locking box 501 and a right locking box 502. The left locking box 501 and the right locking box 502 are fastened to each other and fixed by screws. The upper fork plate 51 includes a first guide fork plate 510 and a second guide fork plate 511. The first guide fork plate 510 and the second guide plug plate are respectively fixed to the two sides of the box body 50 by screws. The intersection of the two forked rods of the first guide fork plate 510 and the second guide fork plate 511 and the box body 50 are provided with grooves that penetrate each other to form a docking groove 52.

[0066] The first guide fork plate 510 and the second guide fork plate 511 are both connected to the upper sealing plate 512 and the lower sealing plate 513 on both sides. The upper sealing plate 512 and the lower sealing plate 513 are mutually snap-connected or screwed to the first guide fork plate 510 and the second guide fork plate 511. The first guide fork plate 510 and the second guide fork plate 511 form a closed and complete structure on both sides through the upper sealing plate 512 and the lower sealing plate 513, and the upper fork plate 51 forms a hollow structure, which is lighter than the solid structure and is easier to move.

[0067] like Figure 22 、 Figure 23 and Figure 24 As shown, a telescopic mechanism 54 is provided in the box body 50, and the telescopic mechanism 54 includes a telescopic rod 548 and a telescopic power member that drives the telescopic rod 548 to move back and forth. The telescopic power member can drive the telescopic rod 548 to insert into or withdraw from the docking groove 52, so that the telescopic rod 548 can be inserted into or withdrawn from the docking hole 62 of the lower fork plate 60 inserted into the docking groove 52, thereby realizing the connection or removal of the upper fork plate 51 and the lower fork plate 60.

[0068] Specifically: a lock body 550 and a motor telescopic mounting bracket 544 are fixedly installed in the box body 50 by screws, wherein the lock body 550 is located in the middle position of the box body 50, and a docking slot 52 is provided on the lock body 550, and the motor telescopic mounting bracket 544 is located on one side of the lock body 550; the telescopic power part includes a motor 545, a telescopic rack 546 and a gear 547, the motor 545 is fixedly mounted on the motor telescopic mounting bracket 544, and the output end of the motor 545 is coaxially fixed with the gear 547, the telescopic rack 546 is horizontally slidably matched with the motor telescopic mounting bracket 544, the gear 547 is meshed with the telescopic rack 546, the telescopic rod 548 is fixedly connected to one end of the telescopic rack 546, and through holes are provided on both sides of the lock body 550, and the telescopic rod 548 can move in the through hole to insert into or exit the docking slot 52.

[0069] When the lower fork plate 60 is inserted into the docking slot 52 of the lock body 550, the control motor 545 is started, which will drive the gear 547 to rotate, thereby driving the telescopic rack 546 engaged with the gear 547 to move horizontally, and then drive the telescopic rod 548 to move horizontally in the through hole of the lock body 550 and insert into the docking hole 62 of the lower fork plate 60 or retract from the docking hole 62 of the lower fork plate 60, thereby realizing the disassembly or connection of the lock body docking unit 5 and the hanger docking unit 6.

[0070] Combine Figure 1 and Figure 15 As shown, a controller 3 is installed on the drone 1. The controller 3 is inserted into the power supply port of the drone 1 through a conductive wire 32 and is powered by a power module inside the drone 1. The controller 3 is connected to the motor 545 in the box body 50 through a power supply line 31. The power supply line 31 passes through multiple flexible connecting tubes 41 and enters the box body 50 to be connected to the motor 545 in the box body 50.

[0071] In another embodiment, Figure 23 As shown, a detection sensor 549 is installed in the box body 50, and the detection sensor 549 is electrically connected to the controller 3. The detection end of the detection sensor 549 extends into the inner side of the lock body 550. When the lower fork plate 60 is inserted into the docking slot 52 of the lock body 550, the detection end of the detection sensor 549 will be triggered. After the detection sensor 549 detects the lower fork plate 60, it will send a signal to the controller 3. The controller 3 controls the motor 545 to start, and drives the telescopic rod 548 to be inserted into the docking hole 62 of the lower fork plate 60 to complete the connection. The detection sensor 549 can detect whether the lower fork plate 60 is inserted into the docking slot 52, so that the controller 3 can easily control the start of the motor 545.

[0072] In another embodiment, a locking-in-place switch 542 is installed on the right side of the lock body 550, and the contact end of the locking-in-place switch 542 is located at the through hole on the right side of the lock body 550. An unlocking-in-place switch 541 is installed on the motor telescopic mounting bracket 544, and the unlocking-in-place switch 541 is located on the left side of the telescopic rack 546 and is arranged opposite to the left end of the telescopic rack 546. The locking-in-place switch 542 and the unlocking-in-place switch 541 are both electrically connected to the controller 3.

[0073] When the telescopic rod 548 is extended and inserted into the docking hole 62 of the lower fork plate 60 and contacts the locking position switch 542, the locking position switch 542 receives a signal that the telescopic rod 548 is connected and locked with the lower fork plate 60, and sends a locking position signal to the controller 3. The controller 3 controls the motor 545 to stop forward rotation. At this time, the lock body docking unit 5 and the hanger docking unit 6 are connected and locked. As the telescopic rod 548 retracts away from the lower fork plate 60, when the left end of the telescopic rack 546 contacts the unlock position switch 541, the unlock position switch 541 sends a signal to the controller 3, which controls the motor 545 to stop reverse rotation. At this time, the lock body docking unit 5 and the hanger docking unit 6 are separated and unlocked. The unlock position switch 541 and the lock position switch 542 can control the extension and retraction travel of the telescopic rod 548 to prevent damage caused by overtravel collision or insufficient travel that may result in the docking assembly and the mounting assembly failing to dock and lock.

[0074] In another embodiment, a button switch 543 is further installed on the box body 50. The button switch 543 is connected to the motor 545. The button switch 543 can serve as an emergency stop. By pressing the button switch 543, the motor 545 can be started and shut down. This makes it convenient to press the button switch 543 to stop the motor 545 when a control system failure occurs.

[0075] During use, the docking assembly's connection unit 4 is first connected to the drone 1 on the ground. The mount assembly's docking unit 6 is then connected to the lock body docking unit 5. The lower fork plate 60 of the docking unit 6 is inserted into the docking slot 52 of the upper fork plate 51 of the lock body docking unit 5. The motor 545 is then driven to insert the telescopic rod 548 into the docking hole 62 of the lower fork plate 60, completing the locking connection. The anti-fall rope is secured to the mounting ring 75 of the pylon 7.

[0076] Then the pilot controls the drone 1 to take off. In the process of driving the docking assembly and the mounting assembly connected to the docking assembly to move upward, the hanger 7 in the mounting assembly will slide downward with the hanger docking unit 6 under the action of its gravity. At this time, the hanger docking unit 6 is in an upward sliding state relative to the hanger 7, which will produce a tightening effect on the connecting piece 79 connected to it. At the same time, the connecting piece 79 drives the locker and the locking bar 90 to unlock, so that the connecting piece 79 can pull the retracting slider 76 to the starting position while the hanger docking unit 6 continues to move upward. At this time, the retracting slider 76 is opened to a large extent, which is convenient for hanging on poles of different sizes in the later stage.

[0077] The drone 1 transports the entire device to the top of the mounting point on the transmission tower, adjusts its position and direction by shooting the picture, and then drops vertically to the angle steel 100 at the mounting point of the tower, gradually approaching the angle steel 100. The angle steel 100 is slid into the locking range between the stop plate 700 and the guide plate 72 by relying on the guide rope 74, and the angle steel 100 is slid into the side of the stop plate 700 by relying on the guide rope 74. At this time, the docking unit 6 of the rack is in a state of sliding downward and resetting. At this time, the connector 79 is loose, and the connector 79 drives the locker and the locking bar 90 to be in a locked state again. When the cam 76 is in the closed position, the spring 8 will pull the retracted slider 76 toward the end position to clamp the angle steel 100 of the pole tower, thereby fixing the pylon 7 and the pole tower angle steel 100. In the process of the retracted slider 76 moving toward the end position, the anti-retraction block 96 can be driven to move unidirectionally along the locking strip 90. When the retracted slider 76 moves to the end position and clamps the pole tower angle steel 100 together with the stop plate 700 on one side of the pylon, the retracted slider 76 no longer moves, and the anti-retraction block 96 also no longer moves. Therefore, when the retracted slider 76 clamps the pole tower, the anti-retraction block 96 and the locking strip 90 produce a locking effect. Since the bracket docking unit 6 has not tightened the connecting piece 79 at this time, the connecting piece 79 is in a loose state. At this time, the locker, under the action of the return spring 95, causes the two anti-retraction blocks 96 to expand outward and be in a locked state with the locking strip 90. At this time, the anti-retraction blocks 96 will not move in the opposite direction, ensuring that the retracting slider 76 will not retreat, thereby strengthening the stability of the connection between the retracting slider 76 and the pole tower, avoiding the entire mounting device from shaking and the retracting slider from retreating when a person slips and is subjected to sudden and continuous force during the operation, thereby avoiding the situation where people fall and the operation safety is improved.

[0078] After the pilot confirms that the mounting assembly is mounted in place by shooting the picture, the controller 3 controls the motor 545 to reverse and drive the telescopic rod 548 to retract and exit the docking hole 62 on the lower fork plate 60, thereby separating the docking assembly and the mounting assembly.

[0079] Control the drone 1 to return, and the staff can now climb the tower using the anti-fall rope.

[0080] When the tower climbing operation is completed and the mounting assembly needs to be removed, the drone 1 drives the docking assembly to fly above the mounting assembly, and the upper fork plate 51 in the lock body docking unit 5 is docked with the lower fork plate 60 in the hanger docking unit 6 in the air, and the motor 545 drives the telescopic rod 548 to pass through the docking hole 62 of the lower fork plate 60, so that the upper fork plate 51 and the lower fork plate 60 are docked.

[0081] Then the drone 1 is controlled to fly upward, and the fixed section 64 in the mount docking unit 6 is driven to slide upward, thereby driving the connecting piece 79 to tighten. At this time, the connecting piece 79 will pull the push rod 92 toward the starting position, and the anti-return block 96 and the locking strip 90 are unlocked. At this time, as the fixed section 64 continues to slide upward, the entire retractable slider 76 can be driven to move toward the starting position, thereby moving away from the loosened angle steel 100. In this way, the drone 1 can take the entire device away and remove the mounting assembly from the angle steel 100. Finally, the drone 1 flies back and brings the entire device back to the ground.
