Description
Technical Field
[0001] This utility model relates to the technical field of tower climbing auxiliary equipment, specifically to a tower climbing fall protection device. Background Technology
[0002] Currently, regulations stipulate that fall protection measures must be provided for high-altitude operations, especially in high-risk scenarios such as power poles and towers. Pole and tower heights of 30 meters and above must be equipped with fall protection devices.
[0003] Power grid workers frequently climb power transmission towers during routine maintenance. Initially, manual pre-climbing is required, but the first worker ascends without a fall arrest 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 off, and the bolts may deform or break due to impact, compromising reliability. Additionally, traditional methods require manual alternation of fall arrest hooks, which is physically demanding and increases the risk of falls.
[0004] 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.
[0005] However, due to the significant differences in the width of the angle steel at the top of transmission towers under different tower types and voltage levels, the existing mounting devices cannot be adapted to angle steels of different widths. Furthermore, 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 personnel accidentally fall and cause a momentary and continuous impact on the mounting devices, the mounting devices are prone to tilting or even falling, thus posing a risk of personnel falling. Utility Model Content
[0006] This utility model provides a tower climbing fall protection device, which aims to prevent people from falling and ensure the safety of personnel during operation.
[0007] This utility model is achieved through the following technical solution:
[0008] A tower fall protection mounting device includes a mounting bracket docking unit and a mounting bracket, wherein the mounting bracket docking unit is connected to the mounting bracket;
[0009] 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.
[0010] The hanger is equipped with a locking unit for restricting the retraction of the retractable slider.
[0011] Furthermore, the hanging bracket docking unit is vertically slidably engaged with the hanging bracket. The driving component includes a connector, 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.
[0012] One end of the connector is connected to the hanger docking unit, and the other end of the connector is connected to the retractable slider.
[0013] Furthermore, the locking 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 bracket. The locking device and the locking bar can lock together.
[0014] When the hanging bracket docking unit slides upward, the connector drives the locking device to unlock from the locking bar, and at this time the connector can drive the retractable slider to move to the starting position;
[0015] When the hanging bracket docking unit slides down to reset, the connector drives the locking device to lock with the locking bar. At this time, the driving device can drive the retractable slider to move towards the end position. During the movement of the retractable slider towards the end position, it can drive the locking device to move unidirectionally along the locking bar.
[0016] Furthermore, the locking device includes a fixed block, a push rod, and an anti-reverse locking block. The fixed block is fixedly connected to the retractable slider, the push rod passes horizontally through the fixed block, the anti-reverse locking block is rotatably connected to the fixed block, and the anti-reverse locking block has a slot, which is inclined.
[0017] One end of the push rod is connected to a push block, and the other end of the push rod is connected to the connector. A return spring is sleeved on the outside of the push rod. The two ends of the return spring abut against or connect to the fixed block and the push block, respectively. A drive block is connected to the bottom of the push block, and the drive block is located in the slot.
[0018] When the reset spring is in the reset state, the driving block drives the anti-reverse block to expand outward and lock with the locking bar; when the connecting member pulls the push rod towards the starting position, the reset spring is compressed, and the driving block slides in the slot and drives the anti-reverse block to retract inward and unlock with the locking bar.
[0019] Furthermore, there are two locking bars, which are respectively connected to the two side walls of the bracket. There are two anti-reverse blocks, which are rotatably connected to the fixing block. The slots on the two anti-reverse blocks are inclined to each other to form a figure-eight structure. There are two driving blocks at the bottom of the push block, which are respectively located in the slots of the two anti-reverse blocks.
[0020] Furthermore, both the locking bar and the anti-reverse block have multiple interlocking locking teeth on their opposite sides, and the anti-reverse block can be engaged with the locking bar to lock when it unfolds outward.
[0021] 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.
[0022] 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.
[0023] Furthermore, the fixed section is detachably connected to the lower fork plate.
[0024] Furthermore, a connecting seat is connected between the fixed section and the lower fork plate. The connecting seat includes an upper quick-release box and a lower quick-release box. The lower fork plate is fixedly connected to the upper quick-release box, the fixed section is fixedly connected to the lower quick-release box, and the upper quick-release box and the lower quick-release box are detachably connected.
[0025] The bottom of the upper quick-release box has a notch for the fixed section to pass through, and both sides of the lower quick-release box are fixedly connected with locking blocks, each of which has a locking hole.
[0026] The upper quick-release box has a spring seat fixedly connected inside. Both sides of the upper quick-release box are laterally slidably fitted with quick-release buckles. One end of the quick-release buckle protrudes from the upper quick-release box, and the other end of the quick-release buckle is connected to the spring seat with a compression spring. The inner side of the quick-release buckle is vertically connected with a hook. The hook is L-shaped and can be locked in the locking hole of the buckle block. Pressing the two quick-release buckles inward can move the two hooks away from the two locking holes.
[0027] Furthermore, the hanger 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 hanger docking unit is vertically slidably engaged with the sliding block.
[0028] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0029] 1. The tower climbing fall arrestor mounting device of this application includes a mounting bracket docking unit and a mounting bracket. The mounting bracket docking unit can be connected to a docking device on a drone, 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.
[0030] Furthermore, this application includes a retractable slider that slides horizontally on the hanger, as well as a drive component that drives the retractable slider to move. When the hanger is hung on the tower, the retractable slider is driven to move towards the end position of the hanger, thereby engaging and locking the retractable slider with one side of the hanger to secure it to the tower, ensuring the stability of the entire tower fall protection device of this application after installation.
[0031] In addition, this application also includes a locking device and a locking bar. The locking and unlocking states of the locking device and the locking bar are achieved by the up-and-down sliding movement of the hanger docking unit. Since the connector is connected to the hanger docking unit, the movement of the connector can drive the locking device and the locking bar to unlock or lock each other. Specifically: Since the hanger docking unit is vertically sliding with the hanger, the up-and-down sliding movement of the hanger docking unit is driven by the drone to move the docking device and the tower fall protection mounting device of this application connected to the docking device upward. During this process, the hanger will slide downward with the hanger docking unit under its own gravity. At this time, the hanger docking unit is in an upward sliding state relative to the hanger. At this time, it will tighten the connector connected to it. At this time, the connector will drive the locking device and the locking bar to unlock. The connector can pull the retractable slider to move to the starting position. At this time, the retractable slider opens to a large extent, which makes it easy to hang on towers of different sizes.
[0032] After the drone moves the entire device to the anchor point on the tower, it is slowly lowered until the bracket lands on the angle steel of the tower. At this point, the bracket docking unit slides downwards to reset, the connector loosens, and the connector drives the locking device and locking strip to re-lock. The drive mechanism then pulls the retractable slider towards the end point to clamp the angle steel of the tower, thus fixing the bracket to the tower angle steel. After the bracket is fixed to the tower angle steel, the drone and docking device will leave the tower fall protection device of this application. At this time, the bracket docking unit is in the reset state, the connector is not tightened, and the locking device and locking strip are locked. As the retractable slider moves towards the end point, it drives the locking device to move unidirectionally along the locking strip. Once the retractable slider reaches the end point and clamps the tower angle steel, the retractable slider stops moving. The locking device also stops moving. Since the locking device moves unidirectionally along the locking bar, when the retractable slider clamps the tower, the locking device and the locking bar create a locking effect. At this time, the locking device will not move in the opposite direction, ensuring that the retractable slider will not retract, thereby strengthening the stability of the connection between the retractable slider and the tower. This prevents the entire device from tilting, loosening, and falling due to a sudden and continuous impact on the support structure if a person falls during operation, thus preventing the device from tilting, loosening, and falling. The tower climbing fall protection device of this application can be stably fixed to the angle steel of the tower. In the event of a person falling, it ensures the stability of the device and prevents the device from shaking, tilting, or the retractable slider from retracting due to a sudden and continuous force on the device during operation, thereby preventing personnel from falling and improving operational safety.
[0033] 2. The cooperation between the locking device and the locking bar in this application can improve the stability of the entire tower fall arrest device installed on the tower, avoid the phenomenon of retracting slider and shaking of the entire device, and make it safer to use.
[0034] 3. The installation process in this application is simple. A drone can be used to move the tower fall arrestor of this application to the tower anchoring point. The vertical displacement of the bracket docking unit causes the connector to drive the locking device and locking strip to unlock or lock. In addition, the drive component drives the retractable slider to move, so that the entire tower fall arrestor is fixedly installed on the tower. The whole operation is simple and does not require manual installation, which effectively improves the installation efficiency and operational safety. When climbing the tower, the worker only needs to connect the fall arrestor on the safety belt to the fall arrestor rope hanging on the bracket to climb the tower. There is no need to use the fall arrestor hook when climbing the tower. Using the device in this application makes the tower climbing process much simpler.
[0035] 4. The distance between the shrinkage slider and the endpoint in this application can be adjusted according to different tower sizes, making it applicable to angle steel of different tower types and more versatile.
[0036] 5. In the locking device of this application, when the return spring is in the reset state, the anti-reverse block expands outward and locks with the locking bar, thus preventing the retracting slider from retracting. When the connecting member pulls the push rod towards 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-reverse block, driving the anti-reverse block to retract inward and unlock from the locking bar. This facilitates the connecting member to pull the retracting slider towards the starting position and away from the angle steel of the tower. At this time, it is convenient to remove the tower climbing fall protection device of this application from the angle steel of the tower after the tower climbing operation is no longer required.
[0037] 6. The driving component for moving the retractable slider in this application includes a coil spring and a coil spring shaft. The coil spring, the connecting piece, and the hanger docking unit achieve a linkage effect. When the hanger docking unit slides upward and causes the connecting piece to tighten and pull the retractable slider to move towards the starting position, the coil spring is stretched. When the hanger docking unit slides downward and causes the connecting piece to loosen and unfold, the coil spring will pull the retractable slider to move towards the end position and clamp it to the pole angle steel.
[0038] 7. In this application, the lower fork plate and the fixed section of the hanging bracket docking unit are detachably connected through the upper quick-release box and the lower quick-release box, which makes it easier to reduce the overall volume and thus facilitate storage and transportation.

[0054] 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.
[0055] As an embodiment of this application, a tower climbing fall protection mounting device is provided. This device 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 tower climbing fall protection mounting device of this application. Then, the drone is used to hang the tower climbing fall protection mounting device of this application and the fall protection rope fixed on the device together onto the angle steel at the top of the tower and lock it in place. This allows the fall protection rope to act as a flexible guide rail, making it convenient for later workers to climb the tower along the fall protection rope.
[0056] like Figure 1 As shown, a tower fall arrest device includes a hanger docking unit 6 and a hanger 7. The hanger docking unit 6 is connected to the hanger. In one embodiment, the hanger docking unit 6 and the hanger 7 are vertically slidably engaged. In another embodiment, the hanger 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.
[0057] In one embodiment, two baffle 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 baffle plates 700. The mounting ring 75 is figure-eight shaped and is used to connect the fall arresting rope. One of the rings of the mounting ring 75 is suspended below the baffle plate 700, and the other ring of the mounting ring 75 is fixed to the lower part of the two baffle plates 700 by a shaft.
[0058] like Figure 1 , Figure 2 and Figure 3As 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.
[0059] 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.
[0060] 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 100 when it is hung 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 100, so that the bracket 7 can be hung more accurately on the tower angle steel 100.
[0061] Combination Figure 2 and Figure 3 As shown, a retractable slider 76 for locking the tower is horizontally slidably fitted on the bracket 7. When the retractable slider 76 slides to its end position, it can engage with one side of the bracket 7 to lock the tower. Specifically: combined with Figure 4 As shown, 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 locked onto the angle steel 100 of the tower and, together with the abutment plate 700 on one side of the bracket 7, achieve the purpose of stably locking and fixing it onto the angle steel 100 of the tower.
[0062] like Figure 4 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.
[0063] 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 3 , Figure 4 , Figure 5 and Figure 6 As shown, the driving component includes a connector 79, 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 hanger 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 hanger 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.
[0064] like Figure 2 As shown, the locking retraction unit includes a locking device 900 and a locking bar 90. The locking device 900 is fixed on the retractable slider 76, and the locking bar 90 is fixed on the bracket 7. The locking device 900 and the locking bar 90 can lock each other. One end of the connector 79 is connected to the bracket docking unit 6, and 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. The movement of the connector 79 can drive the locking device 900 and the locking bar 90 to unlock or lock each other.
[0065] When the hanger docking unit 6 slides upward, the connector 79 drives the lock to unlock from the locking bar 90, 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 lock 900 to lock from the locking bar 90, and at this time the drive can drive the retractable slider 76 to move to the ending position. During the process of the retractable slider 76 moving to the ending position, it can drive the lock 900 to move unidirectionally along the locking bar 90.
[0066] Specifically: In one embodiment, combined with Figure 2 , Figure 5 and Figure 6As shown, the locking device 900 includes a fixing block 91, a push rod 92, and an anti-reverse block 96. The fixing block 91 is fixedly connected to the retractable slider 76. Specifically, the fixing block 91 is fixed to the top of the retractable slider 76 by screws. The fixing block 91 is L-shaped. The push rod 92 passes horizontally through the upper part of the fixing block 91, allowing the push rod 92 to slide horizontally on the fixing block 91. The anti-reverse block 96 is rotatably connected to the lower part of the fixing block 91. The anti-reverse block 96 has a slot 97, which is inclined. The distance between the end of the slot 97 away from the fixing block 91 and the inner side of the anti-reverse block 96 is less than the distance between the end of the slot 97 closer to the fixing block 91 and the inner side of the anti-reverse block 96. The inner side of the anti-reverse block 96 refers to the side away from the locking bar 90.
[0067] In another embodiment, two locking strips 90 are provided, and the two locking strips 90 are respectively connected to the two side walls of the bracket 7. Specifically, the two locking strips 90 are located inside the first side plate 70 and the second side plate 71 of the bracket 7, and the two locking strips 90 are arranged along the length direction of the first side plate 70 and the second side plate 71. The two locking strips 90 are respectively fixed to the first side plate 70 and the second side plate 71 by screws. Two anti-reverse blocks 96 are provided, and the two anti-reverse blocks 96 are symmetrically arranged. Both anti-reverse blocks 96 are rotatably connected to the fixing block 91, and the slots 97 on the two anti-reverse blocks 96 are inclined to each other in a figure-eight shape.
[0068] In one embodiment, one end of the push rod 92 is connected to the push block 94, and the other end of the push rod 92 is connected to the connector 79. In another embodiment, the end of the push rod 92 away from the push block 94 is fixedly connected to the connector 93. A fixing groove is provided on one side of the connector 93. One end of the connector 79 is inserted into the fixing groove, and the connector 79 is fixed in the fixing groove by screws.
[0069] A return spring 95 is sleeved on the outside of the push rod 92. The two ends of the return spring 95 abut or connect to the fixed block 91 and the push block 94 respectively. A drive block (not shown in the figure) is connected to the bottom of the push block 94. The drive block is located in the slot 97. There are two drive blocks at the bottom of the push block 94. The two drive blocks are located in the slots 97 of the two anti-reverse blocks 96 respectively.
[0070] When the reset spring 95 is in the reset state (i.e., when the UAV drives the hanger docking unit 6 downwards onto the tower angle steel 100, the hanger docking unit 6 slides downwards to the reset state, the hanger docking unit 6 does not tighten the connector 79, the connector 79 is in a loose state, and the push rod 92 is not subjected to the tension of the connector 79, so the reset spring 95 will reset), the drive block slides along the slot 97 away from the fixed block 91 under the action of the reset spring 95, thereby driving the anti-reverse block 96 to expand outwards and lock with the locking strip 90 to prevent retraction, thus facilitating the stable fixing of the entire mounting device on the tower angle steel 100.
[0071] Since the connector 79 is in a loose state, the coil spring 8 can pull the retractable slider 76 to slide. Therefore, when the connector 79 is in a loose state, the anti-reverse block 96 expands outward and locks with the locking strip 90, while the coil spring 8 pulls the retractable slider 76 to the end position until the retractable slider 76 stops sliding when it abuts against the angle steel 100 on the tower. During the process of the coil spring 8 driving the retractable slider 76 to slide, the anti-reverse block 96 will retract inward, allowing the retractable slider 76 to move smoothly. When the retractable slider 76 stops moving, the anti-reverse block 96 expands outward under the action of the return spring 95 and locks with the locking strip 90 again, thereby preventing the retractable slider 76 from retracting, improving the stable installation of the entire mounting device, and avoiding the risk of falling for the operators during operation.
[0072] When the hanger docking unit 6 slides upward (i.e., the drone lifts it upward), the connector 79 on the hanger docking unit 6 will tighten. At this time, the connector 79 pulls the push rod 92 towards the starting point. The return spring 95 is compressed, and the drive block slides in the slot 97, driving the anti-reverse block 96 to retract inward and unlock from the locking strip 90. Since the locking device and the locking strip 90 are unlocked, as the connector 79 is gradually pulled upward by the hanger docking unit 6, it will drive the retractable slider 76 to move towards the starting point and away from the ending point. This makes it easier to maintain the maximum distance between the retractable slider 76 and the ending point when installing the tower fall protection device of this application, so as to adapt to different sizes and specifications of tower angle steel 100, and to facilitate the loosening of the angle steel 100 and easy removal when disassembling the tower fall protection device of this application.
[0073] In one embodiment, an anti-slip rubber strip is connected to the inner side of the anti-reverse block 96 and / or locking strip 90. When the anti-reverse block 96 opens outward and abuts against the locking strip 90, the anti-reverse block 96 and the locking strip 90 are locked by friction; while in another embodiment, such as Figure 6 As shown, the locking bar 90 and the anti-reverse block 96 each have multiple interlocking locking teeth on their opposite sides. The locking teeth on the two locking bars 90 are unidirectional helical teeth, similar to ratchet teeth. The locking teeth on the anti-reverse block 96 match the locking teeth on the locking bars 90. When the anti-reverse block 96 unfolds outward, it can engage with the locking bar 90 to lock. In this embodiment, the anti-reverse block 96 and the locking bar 90 are locked together by the engagement of the locking teeth, which can improve the locking effect of both. Moreover, the locking teeth are unidirectional helical teeth, so after the anti-reverse block 96 and the locking bar 90 engage with each other, they can only move in one direction.
[0074] In this embodiment, the anti-reverse block 96 can only move along the locking bar 90 towards the abutment plate 700 of the bracket 7. When the anti-reverse block 96 moves along the locking bar 90 towards the abutment plate 700, the anti-reverse block 96 is in an inward retracted state, which facilitates the smooth movement and engagement of the anti-reverse block 96 on the locking teeth of the locking bar 90. However, when the retracting slider 76 abuts against the angle steel 100 and no longer slides, the anti-reverse block 96 stops engaging with the locking bar 90. At this time, the anti-reverse block 96 expands outward under the action of the return spring 95 and engages with the locking teeth on the locking bar 90. Limited by the locking teeth on the locking bar 90, it cannot retract backward, that is, it cannot retract towards the starting position, thus enabling the entire mounting device to be stably fixed on the tower angle steel 100.
[0075] In one embodiment, such as Figure 2 and Figure 3 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.
[0076] 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 connected to the connector 93 at one end of the push rod 92 on the lock.
[0077] In one embodiment, combined Figure 1 , Figure 3 and Figure 5 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 unmanned control system to quickly identify and find the docking position when the lower fork plate 60 docks with the docking device.
[0078] The fixed section 64 and the bracket 7 slide vertically together. One end of the connector 79 is connected to the fixed section 64. The end of the connector 79 is fixedly connected to the mounting head. The lower part of the fixed section 64 and the mounting head are provided with round holes. After the round hole of the mounting head 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.
[0079] 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.
[0080] 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.
[0081] In one embodiment, the fixed section 64 is fixedly connected to the lower fork plate 60, and the top end of the fixed section 64 is integrally connected to the lower fork plate 60 or fixed by screws or other means; in another embodiment, the fixed section 64 and the lower fork plate 60 are detachably connected, combined with Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, a connecting seat 63 connects the fixed section 64 and the lower fork plate 60. The connecting seat 63 includes an upper quick-release box 631 and a lower quick-release box 635, as shown. Figure 8 and Figure 9 As shown, the lower fork plate 60 is fixedly connected to the upper quick-release box 631, and the lower part of the lower fork plate 60 passes into the upper quick-release box 631 and is fixedly connected to the upper quick-release box 631 by screws.
[0082] like Figure 7 As shown, the fixing section 64 is fixedly connected to the lower quick-release box 635. The fixing section 64 has a T-shaped structure, and the top of the fixing section 64 is fixedly connected to the bottom of the lower quick-release box 635 by screws.
[0083] The upper quick-release box 631 and the lower quick-release box 635 are detachably connected, specifically as follows: Figure 8 and Figure 9 As shown, the bottom of the upper quick-release box 631 has a notch for the fixing section 64 to pass through. When the upper quick-release box 631 and the lower quick-release box 635 are engaged and connected, the top of the fixing section 64 can be inserted into the upper quick-release box 631 through the notch.
[0084] like Figure 7 As shown, both sides of the lower quick-release box 635 are fixedly connected with a locking block 636. The locking block 636 is located above the fixing section 64, and each locking block 636 is provided with a locking hole.
[0085] like Figure 8 and Figure 9 As shown, a spring seat 632 is fixedly connected inside 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 methods. Quick-release latches 633 are laterally slidably fitted on both sides of the upper quick-release box 631. One end of the quick-release latch 633 protrudes from the upper quick-release box 631, and the other end of the quick-release latch 633 is connected to a compression spring 634 between itself and the spring seat 632. A hook 6331 is vertically connected to the inner side of the quick-release latch 633. The hook 6331 is integrally formed with the quick-release latch 633 and is L-shaped. The hooks 6331 on both sides are symmetrical. The two quick-release blocks 636 on the lower quick-release box 635 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 engaged with each other, 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 move the two hooks 6331 away from the two locking holes. At this time, the hooks 6331 are not locked with the locking blocks 636, which makes it easy to separate and disassemble the lower quick-release box 635 and the upper quick-release box 631.
[0086] When connecting the lower fork plate 60 and the fixed section 64, by pressing the two quick-release clips 633 inward, the quick-release clips 633 are prevented from obstructing the locking 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 stored. Then, the lower quick-release box 635 is fastened to the upper quick-release box 631, and the two quick-release clips 633 are released. At this time, the quick-release clips 633 are reset under the action of the compression spring 634, and the hooks 6331 on the quick-release clips 633 engage with the locking holes on the locking block 636 to achieve locking, thereby completing the quick connection between the lower fork plate 60 and the fixed section 64.
[0087] In this embodiment, the lower fork plate 60 and the fixed section 64 are detachably connected, which makes it easy to disassemble them during transportation or storage, reducing the overall volume and making them easier to sell. They are also convenient and quick to assemble and easy to operate.
[0088] The specific implementation process is as follows:
[0089] 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.
[0090] Then, the pilot controls the drone to take off. As the drone moves the docking device and the tower fall protection 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 drives the locking device and locking strip 90 to unlock, so that the connecting piece 79 can 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, which makes it easier to hang on towers of different sizes later.
[0091] The drone transports the entire device to the top of the transmission tower's mounting point. By capturing images, it adjusts its position and orientation, aligning itself with the angle steel 100 at the tower's mounting point, and descends vertically, gradually approaching the angle steel 100. Using the guide plate 72 on the mounting bracket 7, the angle steel 100 slides into the locking range between the stop plate 700 and the guide plate 72. The guide rope 74 then guides the angle steel 100 to one side of the stop plate 700. At this point, the mounting bracket docking unit 6 slides downwards to reset, the connector 79 loosens, and the connector 79 drives the locking device and locking bar 90 to re-lock. In the stopped state, the coil spring 8 will pull the retractable slider 76 towards the end position to clamp the angle steel 100 of the tower, thereby fixing the bracket 7 to the angle steel 100 of the tower. As the retractable slider 76 moves towards the end position, it can drive the anti-reverse block 96 to move unidirectionally along the locking strip 90. When the retractable slider 76 moves to the end position and clamps the angle steel 100 of the tower together with the baffle plate 700, the retractable slider 76 will no longer move. At this time, the anti-reverse block 96 will also no longer move. Therefore, when the retractable slider 76 clamps the tower, the anti-reverse block 96 and the locking strip 90 will produce a locking effect.
[0092] 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, under the action of the return spring 95, the locking device causes the two anti-reverse blocks 96 to expand outward and lock with the locking strip 90. At this time, the anti-reverse blocks 96 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 prevents the entire hanger from shaking and tilting or the retractable slider from retracting due to sudden and continuous force caused by personnel falling during operation, thus avoiding personnel falling and improving work safety.
[0093] 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.
[0094] The drone is then brought back, allowing staff to climb the tower using safety ropes.
[0095] 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.
[0096] 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 push rod 92 towards the starting position, thereby unlocking the anti-reverse block 96 and the locking strip 90. As the fixed section 64 continues to slide upward, it will drive the entire retractable slider 76 to move towards the starting position and away from the released angle steel 100. In this way, the drone can take the entire docking device and mounting device away and remove the mounting device from the angle steel 100. Finally, the drone flies back and brings the mounting device back to the ground.
