Detailed implementation mode

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] Embodiment: As Figure 1-3 and Figure 7-8 shown, an anti-falling device assembly for a drone of the present invention includes a hoisting controller 1 installed at the bottom of the drone cabin, which is composed of a hoisting seat 11, a sealing plate 12 installed at the opening of the hoisting seat 11, and a hoisting mechanism arranged in the hoisting seat 11;

[0040] A hook component 7 arranged on the outer side of the hoisting seat 11, which is composed of a suspension 71 controlled by the hoisting mechanism, a hook 73 installed at the bottom of the suspension 71, and a locking abutment plate 72 rotatably connected to the hook 73 through a rotating shaft, and the locking abutment plate 72 is also controlled by the hoisting mechanism;

[0041] A hanger 2 cooperating with the hook component 7, which is suspended on the tower by the drone. The hanger 2 is composed of a suspension frame 21, a U-shaped hanging plate 25 slidably arranged in the suspension frame 21, a triple-fork fastener 24 rotatably arranged on one side of the suspension frame 21, and a double-fork fastener 23 rotatably arranged on the other side of the suspension frame 21. Interlocking components 29 are arranged on both sides of the U-shaped hanging plate 25;

[0042] A hanging rod 6 installed on one side of the suspension frame 21 and a hanging buckle 3 hung on the hanging rod 6, and a safety rope 4 is connected to the hanging buckle 3.

[0043] Specifically, an installation groove for installing the locking abutment plate 72 is opened on the hook 73, and the arranged installation groove is also beneficial to the movement of the locking abutment plate 72.

[0044] Among them, as Figure 2-6 shown, the lifting mechanism includes an electric push rod 16 installed in the lifting seat 11, a two-way transmission frame 15 pushed by the electric push rod 16, and a rotating rod 17 arranged inside the two-way transmission frame 15 and used to connect the suspension 71. Both ends of the rotating rod 17 penetrate through the lifting seat 11 and are rotatably connected to the lifting seat 11 through bearings. A transmission gear 19 is sleeved and fixed in the middle of the rotating rod 17. A winding rod 18 is arranged on one side of the rotating rod 17. A connecting rope 13 is wound around the winding rod 18. The free end of the connecting rope 13 is connected to the locking abutting plate 72;

[0045] The two-way transmission frame 15 is composed of a transmission tooth plate 151 meshing with the transmission gear 19 and a U-shaped transmission tooth rail 153. Two U-shaped connecting pieces 152 arranged face to face are installed between the transmission tooth plate 151 and the U-shaped transmission tooth rail 153. One side of the U-shaped connecting piece 152 is connected to the inner wall of the lifting seat 11 through a buffer spring 14, and the piston rod of the electric push rod 16 is connected to the U-shaped transmission tooth rail 153 through an L-shaped connecting piece.

[0046] By extending the electric push rod 16 to control the movement of the two-way transmission frame 15, and using the meshing transmission between the transmission tooth plate 151 and the transmission gear 19, and the meshing transmission between the U-shaped transmission tooth rail 153 and the transmission tooth ring 183, the transmission gear 19 and the transmission tooth ring 183 drive the rotating rod 17 and the winding rod 18 respectively, and the rotating directions of the rotating rod 17 and the winding rod 18 are opposite. The rotating rod 17 drives the hook 73 to rotate through the suspension 71. The winding rod 18 winds up the connecting rope 13. The connecting rope 13 pulls the locking abutting plate 72 to make it rotate, so that an opening is formed between the hook 73 and the locking abutting plate 72, thereby facilitating the drone to hang the hook 73 on the hanging ring 271. When the hook 73 passes through the hanging ring 271, the electric push rod 16 retracts. While the hook 73 resets to complete the hanging connection, the locking abutting plate 72 will rotate into the inner side of the hook 73 and abut tightly against the hanging ring 271 to complete the connection between the hook member 7 and the hanger 2.

[0047] Specifically, a plurality of connection holes are provided on the U-shaped transmission tooth rail 153, which not only facilitates the installation of the U-shaped connecting piece 152, but also facilitates the connection with the electric push rod 16. A through hole through which the connecting rope 13 can pass is provided on the sealing plate 12. The existence of the through hole enables the connecting rope 13 to pass through the lifting seat 11, facilitating the connection between the connecting rope 13 and the locking abutting plate 72.

[0048] Among them, as Figure 3 and Figure 6 shown, the winding rod 18 includes a main rod 181 rotatably connected to the lifting seat 11. Two transmission baffles 182 are sleeved outside the main rod 181. A receiving space 184 capable of accommodating the connecting rope 13 is formed between the two transmission baffles 182. A transmission tooth ring 183 meshing with the U-shaped transmission tooth rail 153 is arranged on one side of the transmission baffle 182.

[0049] The main rod 181 is driven to rotate by the transmission gear ring 183 to realize the retraction and release of the connecting rope 13. The transmission gear ring 183 and the connecting rope 13 are separated by the transmission baffle 182, which can effectively prevent the connecting rope 13 from being entangled on the transmission gear ring 183, thereby making the operation of the lifting mechanism more stable.

[0050] Among them, Figure 3 and Figure 4 As shown, the transmission gear plate 151 is provided with an avoidance hole 154 , and the avoidance hole 154 is used to avoid the connecting rope 13 .

The sliding cooperation between the transmission part 251 and the limiting slide groove 212 is utilized to improve the stability of the U-shaped hanging plate 25 during movement, so that the operation of the mechanism is more stable.

[0052] Among them, Figure 8 and Fig. 9 As shown, a movable rod 26 that slides with the connecting hole is installed on the top of the U-shaped hanging plate 25, and a connecting spring 28 is sleeved on the outer wall of the movable rod 26. The two ends of the connecting spring 28 are respectively connected to the U-shaped hanging plate 25 and the suspension plate 22. A hanging plate 27 that can be inserted into the rectangular receiving groove is fixed to the upper end of the movable rod 26. A hanging ring 271 that cooperates with the hook 73 is provided on the top of the hanging plate 27, and two transmission parts 251 that are symmetrically distributed and slide with the limiting slide groove 212 are provided on both sides of the U-shaped hanging plate 25.

[0053] The UAV (the camera on which should be able to take real-time photos of the hanging operation) lifts the hanging plate 27 with the help of the hook component 7, and uses the movable rod 26 to move the U-shaped hanging plate 25 upward in the suspension frame 21, and squeezes the connecting spring 28 through the U-shaped hanging plate 25. At the same time, the meshing transmission of the transmission part 251 and the annular meshing part 293 is used to make the interlocking assembly 29 control the double-pronged fastener 23 and the three-pronged fastener 24 to open. After the UAV flies above the tower with the hanger 2, the suspension frame 21 is placed on the tower from top to bottom, and then the UAV flies vertically downward, and the hanging plate 27 moves downward with the help of the movable rod 26 with the U-shaped hanging plate 25.

[0054] Among them, Figure 7-9 As shown, the interlocking assembly 29 includes a short transmission rod 292 rotatably arranged in the installation groove 211 and a long transmission rod 291 for connecting the double-pronged fastener 23 or the three-pronged fastener 24, and the long transmission rod 291 is transmission-connected to the short transmission rod 292 through a transmission belt, and both ends of the long transmission rod 291 pass through the suspension frame 21 and are rotationally connected thereto, and an annular meshing portion 293 meshing with the transmission portion 251 is provided on the outer wall of the short transmission rod 292.

[0055] The short transmission rod 292 is rotated by the meshing transmission between the transmission part 251 and the annular meshing part 293 , and the short transmission rod 292 drives the long transmission rod 291 with the help of the transmission belt, so that the two-pronged fastener 23 and the three-pronged fastener 24 are opened or crossed together.

[0056] Among them, Figure 7 As shown, the hanging rod 6 is provided with a plurality of hanging holes 61, and the hanging rod 6 is divided into a plurality of hanging points through the hanging holes 61. The hook 3 can be hung on any hanging point, but in actual use, it is best to hang it on the top hanging point. If the current hanging point breaks, the hanging point below can be used as a buffer to prevent construction workers from falling, which is safer.

[0057] The drone fall arrester includes a self-locking fall arrester body 5 and the above-mentioned drone fall arrester assembly. The self-locking fall arrester body 5 is arranged on the outside of the safety rope 4.

After the UAV flies above the tower with the hanger 2, the hanger 21 is placed on the tower from top to bottom, and then The drone flies vertically downward, and the hanging plate 27 moves downward with the U-shaped hanging plate 25 by means of the movable rod 26. The double-pronged fastener 23 and the three-pronged fastener 24 are clamped on the tower under the drive of the long transmission rod 291, and cooperate with the U-shaped hanging plate 25 to enable the hanger 2 to be buckled on the tower. Then the drone cooperates with the lifting controller 1 to control the hook member 7 to release the lifting ring 271, and the drone flies back to the ground with the lifting controller 1 and the hook member 7. After the construction personnel connect the self-locking fall arrester body 5 with the high-altitude work safety belt worn on their bodies, they can climb up to perform corresponding operations;

[0059] When the hanger 2 needs to be removed, the drone flies above the hanger 2 with the hook component 7 and the lifting controller 1. With the cooperation of the drone and the lifting controller 1, the hook 73 is hooked with the lifting ring 271. Then the drone flies upward, lifts the hanging plate 27, opens the double-pronged fastener 23 and the three-pronged fastener 24, and the hanger 2 can be removed.
