Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude operations, and in particular to an automatic unhooking type unmanned aerial vehicle anti-fall rope installation tool. Background Art

[0002] At present, as the main artery of power transmission, overhead transmission lines need to be climbed to eliminate overhead transmission line faults in order to ensure extremely high operational reliability. However, during the tower climbing operation, there are problems such as low coverage of the existing transmission line anti-falling rails, uneven supplier quality, and time-consuming and labor-intensive alternating use of safety belts, which seriously affect the safety of tower climbers. In the prior art, when inspecting or repairing overhead transmission lines, the tower anti-falling device used includes foot nails, safety belts and anti-falling hooks. During use, tower climbers use the anti-falling safety belts alternately to climb the tower step by step.

[0003] The inventor has found that the existing anti-falling devices for high-altitude operations have at least the following disadvantages:

[0004] Workers are required to perform high-altitude operations, and in the process of reaching the high-altitude working position, they need to carry a safety rope and use an anti-fall hook to climb step by step. This process is labor-intensive, time-consuming and labor-intensive, with a slow climbing speed, and consumes a lot of physical strength of the workers, seriously affecting work safety and work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic unhooking type UAV anti-fall rope installation tool, which can reduce labor intensity and improve installation efficiency. At the same time, it is not easy for the tool to fall and be damaged due to missing hanging or misoperation, or hit people or objects, thereby reducing the probability of safety accidents.

[0006] The embodiment of the utility model is achieved as follows:

[0007] In a first aspect, the utility model provides an automatic unhooking type anti-fall rope installation tool for unmanned aerial vehicle, which is used to hang the anti-fall rope on a support, comprising:

[0008] A safety lock mechanism, the safety lock mechanism comprising a lock seat and a first lock core assembly, the lock seat being provided with a lock hole having an opening, the first lock core assembly being mounted on the lock seat, the first lock core assembly being used to descend after the lock seat is supported by the support and the position is restricted, so as to automatically lock the opening;

[0009] And a suspension unhooking mechanism, which includes a lock box, a second lock core assembly and an installation buckle, the lock box and the lock seat are slidably matched, the second lock core assembly is installed in the lock box and locks the installation buckle, and the installation buckle is used to connect with the drone; the second lock core assembly is used to trigger unlocking after the support enters the lock hole, so that the installation buckle automatically detaches from the second lock core assembly.

[0010] In an optional embodiment, the first lock core assembly includes a force transmission rod, a linkage rod and a locking rod, the force transmission rod is slidably connected to the lock seat in a preset direction; the locking rod is movably connected to the lock seat, and the force transmission rod and the locking rod are transmission-connected through the linkage rod; when the force transmission rod slides relative to the lock seat, the force transmission rod drives the locking rod to switch between the first position and the second position through the linkage rod; when in the first position, the locking rod closes the opening, and when in the second position, the locking rod opens the opening;

[0011] The force transmission rod is fixedly connected to the lock box.

[0012] Based on the above scheme, after the drone is lifted and the lifting buckle is installed, the safety lock mechanism can be raised together with the drone under the drive of the force transmission rod. The lock seat descends relative to the force transmission rod under the action of gravity, and the locking rod is automatically in the second position of opening the opening on the lock seat. When the drone moves with the safety lock mechanism to the top of the support, such as the pole tower cross bar, by fine-tuning the position of the drone, the opening is directly above the pole tower cross bar, the drone descends, the pole tower cross bar enters the lock hole of the lock seat from the opening, and contacts the lock seat, the drone continues to descend, and after the lock seat overlaps the pole tower cross bar, the pole tower cross bar restricts the lock seat from descending. At this time, the lock box descends with the force transmission rod, and the force transmission rod drives the locking rod to move through the linkage rod, and the locking rod switches from the second position to the first position. In this way, the locking rod closes the opening on the lock seat, realizing the coordination between the safety lock mechanism and the pole tower cross bar.

[0013] In an optional embodiment, the first lock core assembly further includes an anti-rotation component, which is movably connected to the lock seat so that the anti-rotation component has a locking position and an unlocking position that can be switched between each other; when in the locking position, the anti-rotation component can limit the locking rod from moving from the first position to the second position; when in the unlocking position, the locking rod can move from the first position to the second position.

[0014] Based on the above scheme, when the drone controls the safety lock mechanism to be suspended on the pole tower cross bar, the anti-rotation part moves with the movement of the locking rod. When the locking rod is in the first position, that is, the locking rod locks the opening of the lock hole, the anti-rotation part is just in the locked position. In this state, if the force transmission rod does not move upward, the locking rod cannot automatically open the opening, preventing the lock seat from automatically falling off the pole tower cross bar, thereby improving safety. When the lock seat needs to be removed from the pole tower cross bar, the drone drives the lock box to rise, thereby pulling the force transmission rod to rise, and the external force is transmitted to the locking rod through the linkage rod, driving the locking rod to move relative to the lock seat, and the locking rod switches from the second position to the second position, opening the opening, and the drone can continue to rise and separate the lock seat from the pole tower cross bar from the top of the pole tower cross bar.

[0015] In an optional embodiment, the anti-rotation component is installed on the force transmission rod, and the force transmission rod can drive the locking rod to switch from the first position to the second position after driving the anti-rotation component to switch from the locked position to the unlocked position.

[0016] Based on the above solution, the anti-rotation component and the force transmission rod are closely matched, and the movement of the anti-rotation component is synchronized with the force transmission rod, which is conducive to control.

[0017] In an optional embodiment, the locking rod is rotatably connected to the lock seat, the force transmission rod is rotatably connected to the linkage rod, and the force transmission rod is rotatably connected to the locking rod, and the force transmission rod is used to drive the locking rod to rotate when sliding along the preset direction relative to the lock seat, so that the locking rod can switch between the first position and the second position.

[0018] Based on the above solution, when the force transmission rod is raised or lowered relative to the lock seat, the force transmission rod can drive the locking rod to rotate through the linkage rod, so that the locking rod switches between the first position and the second position, which is convenient and flexible to operate.

[0019] In an optional embodiment, a limiting slot is provided on the locking rod, and the limiting slot has a limiting slot wall; when in the locked position, the anti-rotation component is inserted into the limiting slot, and the anti-rotation component and the limiting slot wall have an avoidance space in the rotation direction of the locking rod, and the anti-rotation component is used to abut against the limiting slot wall to limit the locking rod from switching from the first position to the second position; when in the unlocked position, the anti-rotation component leaves the limiting slot; in the process of the force transmission rod driving the anti-rotation component to switch from the locked position to the unlocked position, the limiting slot wall can rotate in a direction close to the anti-rotation component.

[0020] Based on the above scheme, the anti-rotation part and the locking rod have a tight matching structure. When the locking rod is in the first position to close the opening, the anti-rotation part is inserted into the limit slot and contacts the limit slot wall of the limit slot. If the force transmission rod is not subjected to an upward pulling force, the locking rod rotates from the first position to the second position. The limit slot wall on the locking rod will contact the anti-rotation part. The anti-rotation part limits the rotation of the locking rod, thereby preventing the locking rod from automatically opening the opening of the lock hole. The limiting effect is good and the structure is stable and reliable.

[0021] In an optional embodiment, the second lock core assembly includes a lock body, an unlocking member and a trigger member, the lock body is installed in the lock box, the mounting buckle is detachably connected to the lock body; the unlocking member is connected to the lock body; the trigger member is slidably engaged with the lock seat and extends into the lock hole, the trigger member is used to approach the unlocking member under the abutment of a support entering the lock hole, so as to trigger the lock body to unlock when the trigger member contacts the unlocking member, so that the mounting buckle automatically detaches from the lock body.

[0022] Based on the above scheme, when the drone is suspended on a supporting object such as a tower cross bar with a safety lock mechanism, if the lock seat drops when the opening below the lock seat is not aligned with the tower cross bar, the lock seat will also be blocked by the tower cross bar and will not continue to drop, but the lock box and the force transmission rod will drop relative to the lock seat together, and the force transmission rod drives the linkage part to move, thereby driving the locking rod to rotate, so that the locking rod closes the lock hole, but the tower cross bar does not enter the lock hole, the tower cross bar will not drive the trigger part to move, and the trigger part will not contact the unlocking part. In this way, the unlocking action of the lock body will not be realized, the installation buckle will not be separated from the lock body, and the drone will continue to carry the entire anti-fall rope installation tooling. Therefore, the operator can know that the suspension operation needs to be re-performed, and the drone will not be separated from the safety lock mechanism, causing the safety lock mechanism to fall and be damaged, or hit people or objects. When re-hanging, the drone first drives the tooling to rise, so that the bottom of the lock seat leaves the pole tower cross bar, and readjusts the relative position of the opening at the bottom of the lock seat and the pole tower cross bar, so that the pole tower cross bar can smoothly fall into the lock hole. After that, the drone descends, the pole tower cross bar and the trigger member contacting the two positions remain unchanged, and the lock seat continues to descend until the trigger member contacts the lock seat so that the trigger member and the lock seat can no longer descend, and then the drone continues to descend, the force transmission rod and the lock box descend, and the lock body located in the lock box descends. When the locking rod closes the opening, the trigger member contacts the unlocking member on the lock body, so that the lock body unlocks the installation buckle, and the installation buckle is separated from the lock body. The drone drives the installation buckle to leave the lock body, completing the operation of hanging the lock seat on the pole tower cross bar. The lock seat is not hung on the pole tower cross bar, but the lock body releases the lock of the installation buckle, which is highly safe.

[0023] In an optional embodiment, the trigger member has a working position and a non-working position that can be switched relative to the lock seat. When in the working position, the lock body is close to the lock seat so that the first lock core assembly locks the opening, and the trigger member contacts the unlocking member, thereby unlocking the lock body; when in the non-working position, the lock body is close to the lock seat so that the first lock core assembly locks the opening, and there is a distance between the trigger member and the unlocking member.

[0024] Based on the above scheme, the trigger member can be switched from the non-working position to the working position only after the support enters the lock hole, and can cooperate with the unlocking member to unlock the installation buckle, which has high safety.

[0025] In an optional embodiment, the automatic detachable UAV anti-fall rope installation tool further includes an installation ring, and the installation ring is used to connect to the UAV when the anti-fall rope is removed.

[0026] Based on the above scheme, when the lock seat needs to be removed from the support, a drone with a hook is used to hang it together with the installation lifting ring. The drone drives the entire tooling to rise, and the force transmission rod, lock box and second lock core assembly rise together first. The force transmission rod drives the locking rod to rotate through the linkage rod, and the locking rod opens the opening. The drone continues to rise and can bring the lock seat up with it, so that the lock seat leaves the pole tower cross bar through the opening on it and completes the separation.

[0027] In an optional embodiment, the automatic unhooking type UAV anti-fall rope installation tool further includes an image collector, which is installed on the installation buckle and is used to obtain the relative position of the opening and the support.

[0028] Based on the above solution, during the operation of the drone, the position of the opening relative to the support is observed through an image collector such as a wireless camera installed on the installation buckle, thereby improving the operation accuracy, reducing the operation difficulty, improving the efficiency, and reducing the suspension cost. In addition, the image collector is installed on the installation buckle, and there is no need to install an additional camera on the drone, which reduces the weight of the drone and makes the drone last longer.

[0029] The beneficial effects of the embodiments of the utility model are:

[0030] In summary, the automatic unhooking type anti-fall rope installation tool provided in this embodiment, by setting a hanging unhooking mechanism, when using an aircraft such as a drone to drive the entire tool to be suspended from a high support through the installation buckle, when the support enters the lock hole from the opening and the first lock assembly locks the opening, since the support is in the lock hole, the support can trigger the second lock core assembly to unlock, the second lock core assembly releases the lock on the installation buckle, the installation buckle is separated from the second lock core assembly, that is, the drone is separated from the lock seat, and the lock seat can be suspended on the support, and the suspension operation is completed safely and reliably. During the suspension process, if the opening on the lock seat is not aligned with the support, and during the operation, after the first lock core assembly closes the opening, since there is no support in the lock hole, that is, the suspension operation fails, the support will not trigger the second lock core assembly to unlock, the installation buckle will not leave the second lock core assembly, and the entire tool is still hoisted by the drone, and the entire tool will not fall off from the drone, that is, there will be no high-altitude falling objects caused by misoperation, reducing the probability of safety accidents.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0042] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the prior art, the drone lifts the lifting ring on the main safety lock through the lifting hook, flies above the pole tower cross bar, and descends. When trying to hang the main safety lock on the pole tower cross bar, the drone is affected by the environment in the air and the shaking of the pilot controlling the drone. If the opening 112 below the main safety lock is not just stuck on the cross bar, but one of the feet falls on the cross bar, and then the drone continues to land, because the combination of the hook and the lifting ring is an open design without a locking structure, the main safety lock may accidentally fall off the hook when it is not properly installed, fall down, and hit people or objects, causing a safety accident.

[0044] In view of this, the designer provides an automatic decoupling type UAV anti-fall rope installation tool. The UAV can be separated from the main safety lock only after the main safety lock and the cross bar are correctly hung, which reduces the probability of safety accidents and improves the safety and reliability of operations.

[0045] Please combine Figure 1In this embodiment, the automatic unhooking type UAV anti-fall rope installation tool is mainly used to use an aircraft such as a UAV to hang the anti-fall rope on a support 001, and the support 001 can be but is not limited to a pole tower crossbar. The automatic unhooking type UAV anti-fall rope installation tool includes a safety lock mechanism 100 and a hanging unhooking mechanism 200. The safety lock mechanism 100 includes a lock seat 110 and a first lock core assembly 120. The lock seat 110 is provided with a lock hole 111 with an opening 112. The first lock core assembly 120 is installed on the lock seat 110. The first lock core assembly 120 is used to descend after the lock seat 110 is supported by the support 001 and the position is restricted to automatically lock the opening 112; the suspension unhooking mechanism 200 includes a lock box 210, a second lock core assembly 220 and an installation buckle 230. The lock box 210 and the lock seat 110 are slidably matched. The second lock core assembly 220 is installed on the lock box 210 and locks the installation buckle 230. The installation buckle 230 is used to connect with the drone; the second lock core assembly 220 is used to trigger unlocking after the support 001 enters the lock hole 111, so that the installation buckle 230 automatically disengages from the second lock core assembly 220.

[0046] Based on the above, the working principle of the automatic unhooking type anti-falling rope installation tool provided in this embodiment is as follows:

[0047] Please combine Figure 3 When using an aircraft such as a drone to drive the entire tooling through the installation hook 230 to make it hang from a support 001 at a high place, when the support 001 enters the lock hole 111 from the opening 112 and the first lock assembly locks the opening 112, since the support 001 is in the lock hole 111, the support 001 can trigger the second lock core assembly 220 to unlock, and the second lock core assembly 220 releases the lock on the installation hook 230. The installation hook 230 is separated from the second lock core assembly 220, that is, the drone is separated from the lock seat 110, and the lock seat 110 can be hung on the support 001, completing the hanging operation safely and reliably. During the hanging process, if the opening 112 on the lock seat 110 is not aligned with the support 001, and during the operation, after the first lock core assembly 120 closes the opening 112, since there is no support 001 in the lock hole 111, that is, the hanging operation fails, the support 001 will not trigger the second lock core assembly 220 to unlock, and the installation buckle 230 will not leave the second lock core assembly 220. The entire workpiece is still hoisted by the drone, and the entire workpiece will not be separated from the drone and fall, that is, there will be no falling objects from high altitude due to misoperation, thereby reducing the probability of safety accidents.

[0048] The following embodiments illustrate the detailed structure of the automatic unhooking type UAV anti-fall rope installation tool provided in the present application by way of example.

[0049] Please combine Figure 1 and Figure 2In this embodiment, optionally, the first lock core assembly 120 includes a force transmission rod 121, a linkage rod 122 and a locking rod 123. The force transmission rod 121 is slidably connected to the lock seat 110 in a preset direction; the locking rod 123 is movably connected to the lock seat 110, and the force transmission rod 121 and the locking rod 123 are transmission-connected through the linkage rod 122; when the force transmission rod 121 slides relative to the lock seat 110, the force transmission rod 121 drives the locking rod 123 to switch between the first position and the second position through the linkage rod 122; when in the first position, the locking rod 123 closes the opening 112, and when in the second position, the locking rod 123 opens the opening 112; the force transmission rod 121 is fixedly connected to the lock box 210.

[0050] It should be understood that when the drone is hoisted and the hanging buckle 230 is installed, the safety lock mechanism 100 can be lifted together with the drone under the drive of the force transmission rod 121. The lock seat 110 descends relative to the force transmission rod 121 under the action of gravity, and the locking rod 123 is automatically in the second position of opening the opening 112 on the lock seat 110. When the drone moves with the safety lock mechanism 100 to the top of the support 001, such as the pole tower cross bar, by fine-tuning the position of the drone so that the opening 112 is directly opposite the top of the pole tower cross bar, the drone descends, and the pole tower cross bar enters the lock hole 111 of the lock seat 110 from the opening 112 and contacts the lock seat 110. The drone continues to descend. After the lock seat 110 overlaps with the pole tower cross bar, the pole tower cross bar restricts the lock seat 110 from descending. At this time, the lock box 210 descends with the force transmission rod 121. The force transmission rod 121 drives the locking rod 123 to move through the linkage rod 122, and the locking rod 123 switches from the second position to the first position. In this way, the locking rod 123 closes the opening 112 on the lock seat 110, thereby realizing the cooperation between the safety lock mechanism 100 and the pole tower cross bar.

[0051] In this embodiment, optionally, the first lock core assembly 120 also includes an anti-rotation component 124, which is movably connected to the lock seat 110 so that the anti-rotation component 124 has a locking position and an unlocking position that can be switched with each other; when in the locking position, the anti-rotation component 124 can limit the locking rod 123 from moving from the first position to the second position; when in the unlocking position, the locking rod 123 can move from the first position to the second position.

[0052] With such a design, when the drone controls the safety lock mechanism 100 to be suspended on the pole tower crossbar, the anti-rotation part 124 moves with the movement of the locking rod 123. When the locking rod 123 is in the first position, i.e., the locking rod 123 locks the opening 112 of the lock hole 111, the anti-rotation part 124 is just in the locked position. In this state, if the force transmission rod 121 does not move upward, the locking rod 123 cannot automatically open the opening 112, thereby preventing the lock seat 110 from automatically falling off the pole tower crossbar, thereby improving safety. When the lock seat 110 needs to be removed from the pole tower crossbar, the drone drives the lock box 210 to rise, thereby pulling the force transmission rod 121 to rise, and the external force is transmitted to the locking rod 123 through the linkage rod 122, driving the locking rod 123 to move relative to the lock seat 110, and the locking rod 123 switches from the second position to the second position, opening the opening 112, and the drone can continue to rise and separate the lock seat 110 from the pole tower crossbar from the top of the pole tower crossbar.

[0053] In this embodiment, the anti-rotation member 124 is optionally installed on the force transmission rod 121, and the force transmission rod 121 can drive the anti-rotation member 124 to switch from the locked position to the unlocked position, and then drive the locking rod 123 to switch from the first position to the second position.

[0054] It should be noted that the anti-rotation member 124 and the force transmission rod 121 are closely matched, and the movement of the anti-rotation member 124 is synchronized with the force transmission rod 121, which is convenient for control. For example, the anti-rotation member 124 can be fixedly connected to the force transmission rod 121 by means of a structural member such as a screw. In addition, the force transmission rod 121 can be a cylindrical rod, and a sliding hole is provided on the lock seat 110. The force transmission rod 121 can be slidably inserted into the sliding hole, and the sliding hole is used to guide the force transmission rod 121 to slide. During normal operation, the entire device is arranged vertically, the force transmission rod 121 is extended vertically, and when the locking rod 123 closes the opening 112, the locking rod 123 is basically extended horizontally.

[0055] In this embodiment, optionally, the locking rod 123 is rotatably connected to the lock base 110, the force transmission rod 121 is rotatably connected to the linkage rod 122, and the force transmission rod 121 is rotatably connected to the locking rod 123. The force transmission rod 121 is used to drive the locking rod 123 to rotate when sliding along a preset direction relative to the lock base 110, so that the locking rod 123 switches between the first position and the second position. When the force transmission rod 121 is raised or lowered relative to the lock base 110, the force transmission rod 121 can drive the locking rod 123 to rotate through the linkage rod 122, so that the locking rod 123 switches between the first position and the second position, and the operation is convenient and flexible.

[0056] Optionally, a limiting slot 1231 is provided on the locking rod 123, and the limiting slot 1231 has a limiting slot wall 1232; when in the locked position, the anti-rotation component 124 is inserted into the limiting slot 1231, and the anti-rotation component 124 and the limiting slot wall 1232 have an avoidance space in the rotation direction of the locking rod 123, and the anti-rotation component 124 is used to abut against the limiting slot wall 1232 to limit the locking rod 123 from switching from the first position to the second position; when in the unlocked position, the anti-rotation component 124 leaves the limiting slot 1231; in the process of the force transmission rod 121 driving the anti-rotation component 124 to switch from the locked position to the unlocked position, the limiting slot wall 1232 can rotate in the direction close to the anti-rotation component 124.

[0057] With such a design, the anti-rotation component 124 and the locking rod 123 cooperate closely. When the locking rod 123 is in the first position to close the opening 112, the anti-rotation component 124 is inserted into the limiting slot 1231 and contacts the limiting slot wall 1232 of the limiting slot 1231. If the force transmission rod 121 is not subjected to the upward pulling force, the locking rod 123 rotates from the first position to the second position. The limiting slot wall 1232 on the locking rod 123 will contact the anti-rotation component 124. The anti-rotation component 124 limits the rotation of the locking rod 123, thereby preventing the locking rod 123 from automatically opening the opening 112 of the lock hole 111. The limiting effect is good and the structure is stable and reliable.

[0058] Please combine Figure 1-Figure 3 In this embodiment, optionally, the second lock core assembly 220 includes a lock body 221, an unlocking member 222 and a trigger member 223. The lock body 221 is installed on the lock box 210, and the mounting buckle 230 is detachably connected to the lock body 221; the unlocking member 222 is connected to the lock body 221; the trigger member 223 is slidably matched with the lock seat 110 and extends into the lock hole 111. The trigger member 223 is used to approach the unlocking member 222 under the abutment of the support 001 entering the lock hole 111, so as to trigger the lock body 221 to unlock when the trigger member 223 contacts the unlocking member 222, so that the mounting buckle 230 automatically detaches from the lock body 221.

[0059] It is worth noting that when the drone is suspended on a support 001 such as a pole tower crossbar with the safety lock mechanism 100, if the lock seat 110 descends without the opening 112 below the lock seat 110 being aligned with the pole tower crossbar, the lock seat 110 will also be blocked by the pole tower crossbar and will not continue to descend. However, the lock box 210 and the force transmission rod 121 will descend relative to the lock seat 110, and the force transmission rod 121 will drive the linkage to move, thereby driving the locking rod 123 to rotate, so that the locking rod 123 closes the lock hole 111, but the pole tower crossbar If the UAV does not enter the lock hole 111, the pole tower cross bar will not drive the trigger member 223 to move, and the trigger member 223 will not contact the unlocking member 222. In this way, the unlocking action of the lock body 221 will not be realized, and the installation hook 230 will not be separated from the lock body 221. The UAV will continue to carry the entire anti-fall rope installation tooling. Therefore, the operator can know that the suspension operation needs to be performed again, and the UAV will not be separated from the safety lock mechanism 100, causing the safety lock mechanism 100 to fall and be damaged, or hit people or objects. When re-suspending, the UAV first drives the tooling to rise, so that the bottom of the lock seat 110 leaves the pole tower cross bar, and readjusts the relative position of the opening 112 at the bottom of the lock seat 110 and the pole tower cross bar, so that the pole tower cross bar can smoothly fall into the lock hole 111. After that, the drone descends, the pole tower cross bar and the trigger member 223 contact the position where the two remain stationary, and the lock seat 110 continues to descend until the trigger member 223 contacts the lock seat 110 so that the trigger member 223 and the lock seat 110 can no longer descend. Then, the drone continues to descend, the force transmission rod 121 and the lock box 210 descend, and the lock body 221 located in the lock box 210 descends. When the locking rod 123 closes the opening 112, the trigger member 223 contacts the unlocking member 222 on the lock body 221, so that the lock body 221 is unlocked, and the lock body 221 releases the lock on the installation buckle 230. The installation buckle 230 is separated from the lock body 221, and the drone drives the installation buckle 230 to leave the lock body 221, completing the operation of hanging the lock seat 110 on the pole tower cross bar. There will be no situation where the lock seat 110 is not hung on the pole tower cross bar but the lock body 221 releases the lock on the installation buckle 230, which has high safety.

[0060] Furthermore, a lock slot 2211 is provided on the lock body 221, and the installation buckle 230 can be inserted into the lock slot 2211 and locked with the lock body 221. The direction of the notch of the lock slot 2211 is set as required. For example, in this embodiment, the notch of the lock slot 2211 faces the side of the lock box 210. In other embodiments, the notch of the lock slot 2211 can also face the top of the lock box 210. In addition, the lock column 224 can be secured at the notch of the lock slot 2211. When the lock column 224 is in a position to close the notch, the installation buckle 230 is inserted into the lock slot 2211 and will not fall out of the lock slot 2211. At the same time, a spring 225 is installed in the lock body 221. The spring 225 is in a compressed state, and the elastic force provided by the spring 225 can pop the installation buckle 230 out of the notch. When the trigger member 223 contacts the unlocking member 222 , the lock column 224 moves relative to the lock body 221 and opens the slot, and the elastic force of the spring 225 is released to push the installation buckle 230 out of the lock slot 2211 , thereby achieving automatic decoupling of the installation buckle 230 from the lock body 221 .

[0061] In addition, the lock column 224 can be controlled by a telescopic device such as an electric push rod, a cylinder or a hydraulic cylinder. When the unlocking member 222 contacts the trigger member 223, the telescopic device is activated, driving the lock column 224 to move and open the slot. The structure of the lock column 224 telescopic switch slot can also refer to other existing structures, which are not exhaustive in this embodiment.

[0062] In this embodiment, optionally, the trigger member 223 has a working position and a non-working position that can be switched with respect to the lock seat 110. When in the working position, the lock body 221 is close to the lock seat 110 so that the first lock core assembly 120 locks the opening 112, and the trigger member 223 contacts the unlocking member 222, thereby unlocking the lock body 221; when in the non-working position, the lock body 221 is close to the lock seat 110 so that the first lock core assembly 120 locks the opening 112, and there is a distance between the trigger member 223 and the unlocking member 222.

[0063] With such a design, the trigger member 223 can be switched from the non-working position to the working position only after the support 001 enters the lock hole 111, and can cooperate with the unlocking member 222 to unlock the installation buckle 230, which has high safety.

[0064] Optionally, the lock box 210 is provided with a guide hole 211, and when the lock box 210 moves close to the lock seat 110, the trigger member 223 can extend into the guide hole 211 to contact the unlocking member 222. In addition, during the hanging process, the trigger member 223 has a tendency to slide toward the opening 112 under its own gravity to leave the lock seat 110, and a step is provided on the trigger member 223 to prevent it from leaving the lock seat 110. In addition, in order to ensure that the support 001 can contact the trigger member 223 after entering the lock hole 111, the portion of the trigger member 223 located in the lock hole 111 is long and extends in the opening direction of the opening 112, that is, the portion of the trigger member 223 located in the lock hole 111 can cover the entire area where the opening 112 is located. In this way, no matter what posture the support 001 enters the lock hole 111 relative to the lock seat 110, when the trigger member 223 descends and approaches the support 001, the portion of the trigger member 223 located in the lock hole 111 can contact the support 001, and the trigger member 223 can always be supported by the support 001, thereby ensuring that the position of the trigger member 223 relative to the lock box 210 remains unchanged. When the lock box 210 and the lock body 221 descend, the trigger member 223 can be inserted into the guide hole 211, so that the trigger member 223 can contact the unlocking member 222.

[0065] In this embodiment, optionally, the automatic unhooking type UAV anti-fall rope installation tool further includes an installation ring 300, and the installation ring 300 is used to connect with the UAV when the anti-fall rope is disassembled.

[0066] When it is necessary to remove the lock seat 110 from the support 001, a drone is used with a hook to be hung together with the installation lifting ring 300. The drone drives the entire tooling to rise, and the force transmission rod 121, the lock box 210 and the second lock core assembly 220 rise together first. The force transmission rod 121 drives the locking rod 123 to rotate through the linkage rod 122, and the locking rod 123 opens the opening 112. The drone continues to rise and can bring the lock seat 110 up, so that the lock seat 110 leaves the pole tower cross bar through the opening 112 thereon, completing the separation.

[0067] In this embodiment, optionally, the automatic unhooking type UAV anti-fall rope installation tool also includes an image collector 400, and the image collector 400 is installed on the installation buckle 230 to obtain the relative position of the opening 112 and the support 001.

[0068] During the operation of the drone, the position of the opening 112 relative to the support 001 is observed by using the image collector 400, such as a wireless camera, disposed on the mounting hook 230, thereby improving the accuracy of the operation, reducing the difficulty of the operation, improving the efficiency, and reducing the hanging cost. In addition, the image collector 400 is disposed on the mounting hook 230, so there is no need to set up an additional camera on the drone, which reduces the weight of the drone and makes the drone last longer.

[0069] It should be understood that the mounting hook 230 may include a rod body 231 and a closed ring 232 connected to each other, the rod body 231 is connected to the drone, and the image collector 400 may be disposed on the rod body 231. The closed ring 232 is snapped into the locking groove 2211.

[0070] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
